    Y Descriptive Report of the Patent of Invention for "DEVICE + FOR ACTIVATION AND RESTORATION OF INTERCEPTOR DEVICE". O
    DESCRIPTION The present invention relates to a device and a process q5 for activating and restoring an interceptor device in an elevator installation, as well as correspondingly equipped elevator installations; corresponding. Elevator facilities are mounted in a building. They substantially consist of an elevator car, which is connected via support cables or support straps with a counterweight. or with a second elevator cabin. By means of a drive, which optionally acts on the support means, directly on the cabin: or the counterweight, the cabin is moved along substantially vertical guide rails. The elevator installation is used to transport people and goods within the building on individual floors or over multiple floors. The elevator installation contains devices to lock the elevator cabin in case of failure of the drive or the means of support and also to protect during a stop on a floor against deviation or fall. For this purpose, in general, intercepting devices are used, which, if necessary, can brake the elevator car on the guide rails. Until today, these intercepting devices were activated by mechanical speed limiters. But increasingly, electronic monitoring devices are now also used, which, if necessary, can activate brake devices or interceptors. In order, despite this, to make use of known and proven intercepting devices, electromechanical activation units are required, which at a corresponding command can activate interceptor devices. A device of this kind is known from document EPO5431154. In this case, an auxiliary gag brake, when needed, is | put into engagement with a guide rail and this auxiliary clamp brake
    — + an existing lever system, with which interceptor devices are activated. This auxiliary gag brake is configured to be able to EE move the lever system and mass parts of the interceptor device. The required electromagnetic units need to be sized A 5 correspondingly large. From US7575009 another device of this kind is known. In this solution, if necessary, intercepting wedges of an interceptor device are activated directly by springs. The springs are under tension and the tensioned springs are released if necessary. The springs can be restored again or tensioned AND by a spindle drive. Also this electromagnet must be dimensioned correspondingly large, since the entire voltage of à. multiple springs need to be directly absorbed and retained. The purpose of the invention is, therefore, to provide at least one alternative solution for activating and restoring an interceptor device in an elevator installation by means of electrical control and its integration in the elevator installation.
    This solution or solutions must be able to be combined with conventional intercepting devices and/or must be secure.
    Other aspects such as quick activation of the interceptor device, low power requirement, simple assembly, behavior of the device in case of power failure or component defects must also be taken into account.
    The solutions defined in the independent patent claims satisfy at least some of these requirements and with their configurations according to the dependent claims, take into account other useful aspects.
    An elevator installation is used to transport goods and people in buildings. The elevator installation contains for this purpose at least one elevator cabin, for receiving people and goods and, in general, a counterweight. The counterweight and the elevator car are connected to each other via a support cable, a lifting strap.
    Y postage or other means of support.
    These support means are guided —————— over a deflection pulley or a drive disc and the counterweight E A 100 therefore fly in opposite directions in the building or in an elevator shaft provided for in the building.
    In order to prevent a fall of the cabin and, if necessary, also of the counterweight, or to prevent other faulty behavior of these moving bodies - for the displacement body both the elevator cabin and the also the counterweight - at least the elevator car, and possibly also the counterweight, are equipped with an intercepting device.
    In this case, the displacement body generally contains two intercepting devices, which are as- ; associated, in each case, with a guide rail.
    Guide rails - usually two guide rails, guide the displacement body along the shaft. elevator and they comprise a rib sore which the interceptor device can engage for the purpose of braking.
    One embodiment of a conventional intercepting device comprises two intercepting wedges.
    The intercepting wedges are mounted and guided vertically displaceable in the interceptor device in the normal operation of the elevator installation, the intercepting wedges are in a lower ready position.
    If necessary, the intercepting wedges are pushed upwards by a device for activating and restoring the interceptor device, along an inclined guideway, until they squeeze the guide rail rib.
    The frictional force formed by the grip now moves - with the interceptor device or displacement body in continued motion - the intercepting wedges further into a housing of the interceptor device, until a wedge abutment.
    By this additional movement, by the wedge effect of the interception wedges, the housing, which is produced in a correspondingly elastic way, is compressed.
    This compression finally determines a compression force of the intercepting wedges on the rib of the guide rails and, therefore, a braking force, which brakes the displacement body.
    According to one aspect of the invention, the device for activating and restoring the interceptor device comprises a single accumulation.
    pressure side, which, if necessary, moves to an "intercept" position the two intercepting wedges of the interceptor device explained above, substantially synchronously, from the ready position to the rib of the guide rail The device further comprises a restoring device, preferably remotely activatable, which is configured to tension the pressure accumulator back into a ready position. This occurs when the displacement cup, after braking and testing has taken place The safety status of the lift installation must be released again.
    The common pressure accumulator enables safe activation of the interceptor device, as the two wedges can be activated simultaneously and free from jamming. The common pressure accumulator can also be simply coupled, for example , through a lever system, in interceptor devices.
    Of course, intercepting devices of other kinds can also be activated correspondingly, such as, for example, a roller blocking interceptor device, in which device interception wedges are activated instead of blocking rollers. - ception or other corresponding interception devices.
    In a variant of configuration, the pressure accumulator comprises a pressure spring, which is tensioned by means of the restoration device and which, if necessary, can release this tension for activating the intercepting wedges. The pressure spring is preferably configured in such a way that, even in the event of a spiral breakage, loss of a winding length and spring extension by the value of this length is present - a sufficient residual force is present to activate - tion of the intercept wedges.
    The use of a pressure spring makes it possible to provide a safe and inexpensive device for activating and restoring the interceptor device. Of course, other pressure accumulators are also possible. Thus, for example, it is also possible to use a pneumatic or hydraulic pressure accumulator.
    In a different or complementary configuration variant, the —————— —-- and intercept are connected with a connection splint on the activator. Because of this, the intercept wedges are guided by the activator. In this way, an intercepting wedge, for example, as a result of oscillations or unilateral contact with the guide rail, is prevented from suddenly activating automatically and thereby leading to undesirable braking. A use of an activator of this kind also enables a space-saving device realization for activating and restoring the interceptor device, since it can be disposed, by e- ; example, lateral to the interceptor device and therefore does not require an additional well height.
    x In a configuration variant, the activator comprises a swivel body, which is pivotally mounted on the horizontal swivel shaft. This swivel body is connected on one side with two lever arms. The two lever arms connect the swivel body with the intercepting wedges. They are advantageously designed in such a way that they can accompany a lateral displacement of the intercepting wedges during activation. This lateral displacement results when the intercepting wedges are pushed upward along their slanted guideway. Advantageously, this lateral compensation is made possible by the fact that the two lever arms are fixed by means of lateral joints on the swivel body or by the fact that the two lever arms have a high lateral elasticity. Naturally, the lever arms are at the same time rigid in the vertical direction to enable quick activation of the intercepting wedges.
    In a modality variant, the activator, in total, and in particular the two lever arms, are made with little mass. This can happen, for example, by arrangement and holes in neutral axes without loaded lever arms. This is advantageous since, in turn, mass inertia can be reduced in turn. Small mass inertia means that rapid activation of the intercept device can be achieved.
    tor.
    F The swivel body is also connected to a control arm. This control arm connects the swivel body with the pressure accumulator or pressure spring and a retaining device. The É 5 holding device retains the activator in the ready position in the normal operation of the ; Elevator installation. As a result, the tension force from the pressure accumulator is guided directly through the control arm to the holding device. The lever arms are therefore freed from this flow of force, they only support the intercepting wedges. Advantageously, the activator arrangement is selected in such a way that the lever arms compress the intercepting wedges from the bottom upwards and the control arm is arranged on the opposite side of the swivel-shaft. In this way, the pressure accumulator can be arranged simply above the control arm, therefore, laterally to the interceptor device. Because of this, the device for activating and restoring the interceptor device does not need additional construction height.
    In another variant of the complementary configuration, the holding device is controlled by an electromagnet. The electromagnet in the normal operation of the elevator installation attracts a retaining latch from the detent device and likewise holds the activator in the ready position against the force of the pressure accumulator. In the event of a decline of the electromagnet, a latch spring opens the retaining latch and the pressure accumulator can compress the intercepting wedges through the activator to their intercepting position. Furthermore, the retaining bar is designed in such a way that it can be moved substantially free of force. This can be achieved by the fact that a curved course, which cooperates with an activator retaining nose, is correspondingly formed. With this, a holding force of the electromagnets can be realized in a small way, since substantially only the holding latch needs to be held in position.
    In a configuration variant, the device for activating and restoring the interceptor device is provided with switches or sensors.
    res for monitoring the status of the device.
    A first + position sensor preferably monitors a working position of the activator and thereby, at the same time, a working position of the intercepting wedges.
    This first position sensor is preferably designed as a safety switch.
    It signals an elevator installation control that the interceptor device is in a braking position so that the control can interrupt or block a travel.
    In general, the signal is guided directly into an elevator installation safety circuit.
    With this, the safety of the elevator installation or the users of the installation can be increased or a requirement of safety standards can thus be met advantageously and safely. fr Preferably, the device for activating and restoring the interceptor device comprises a second position sensor, which monitors a position of the retaining bar of the retaining device.
    This second position sensor is preferably made in the form of a microswitch.
    It can be used, on the one hand, for control of the restoring device and/or, on the other hand, it can also be used for secondary monitoring of the device for activation and restoration of the interceptor device.
    So, for example, in the event of a drop or breakage of the holding bar, this can be quickly identified and a control can also eventually activate other brakes or at least quickly bring the elevator installation to a standstill.
    With this, it is also possible to check the functioning of the first position sensor, since, in general, in the case of the holding latch open, in a short interval this first position sensor also needs to signal an interlocking device. activated receiver.
    In a configuration variant, the retaining device is pivotally mounted by means of a return lever on the swivel shaft of the activator.
    The remotely activatable reset device can move the holding device in a controlled manner from a ready position to a ready position to a reset position.
    AE——]— —— 8/30 tion, and after an engagement of the retaining latch of the retention device ——on the control arm of the swivel body, it may shift. return the holding device, together with the control arm, to the ready position. In this case, together with the movement of the control arm to the ready position, the pressure accumulator or pressure spring is tensioned back into the ready position.
    In a variant with a different or complementary configuration, a third position sensor is provided, preferably also a microswitch. It can monitor the ready position of the restoration device. With this, a device reset can be automated for activating and restoring the intercepting device. In a variant of different or complementary configuration, the : restoration device comprises a spindle drive with a spindle drive and a spindle carriage driven by a spindle of the spindle drive. The spindle carriage is connected with the return lever, whereby the spindle drive can move the return lever. Due to the rotary shaft in common with the activator, the return lever can exactly follow the movement curve of the activator. This allows for exact positioning of the retaining device.
    Alternatively, instead of spindle drive with spindle drive, a hydraulically or pneumatically activated restorative device can be used. In this case, instead of the spindle carriage, a hydraulically or pneumatically activated carriage can be used.
    In total, therefore, by means of the retaining latch, which is controlled by the electromagnet, in such a device for activating and restoring the device, the intercepting wedges can be quickly activated in the event of a release of the latch. of regeneration and the activation performed can be verified quickly. By means of the second position switch, the operation of the first position switch can be monitored and the use of various devices for activating and restoring interceptor devices, in the event of an accidental opening of one of the retaining latches, the others interceptor devices, which work in parallel.
    Unfortunately, they can be quickly put to use.
    This prevents asymmetrical braking Additional safety to prevent asymmetrical braking ac-slits can be obtained by the fact that the electromagnets of interceptor devices are connected in series with their devices for activating and restoring the intercepting devices.
    In the É interruption of the coil of a holding magnet, a current flow over the two holding magnets is thus directly interrupted and the two intercepting devices operating in parallel are activated synchronously or symmetrically. s Furthermore, a device reset for activation and reset can be controlled via the second and third position sensors. ration of the interceptor device.
    As depicted in an example, this course of control can take place as follows.
    A brake was activated by a disconnection of a control circuit of the electromagnets.
    The retaining latch releases the activator and the pressure accumulator pushes the intercept wedges into the intercept position.
    In the interception position, the automatic tightening of the interception wedges on the guide rail rib by friction occurs and the first position switch or the safety switch interrupts the safety circuit of the elevator installation, with which any means of drives are stopped.
    The second position switch, which monitors the position of the detent lock, is also activated.
    By tightening the intercepting wedges, the intercepting device forms a corresponding braking force and stops the displacement body.
    A service technician or a person who has been trained accordingly will clarify the state of the installation and/or the reason for the braking and prepare the lift installation for re-commissioning.
    In general, the service technician will be the first person to get rid of those who may be in the elevator cabin.
    To this end, it moves the elevator car by means of an evacuation control in an upward direction, that is, in opposition to the intercept direction for the next stop.
    The intercepting wedges are in this case moved back by the friction between the intercepting wedges and the guide rail rib, whereby the pressure accumulator is already partially tensioned again.
    The elevator installation is additionally protected, in that case, h 5 against unexpected slippage, since the intercepting wedges continue to be compressed by the pressure accumulator to the intercepting position.
    This means that the interceptor device would immediately brake again, if, for example, the cab were moved down again.
    After casual persons have left the elevator cabin, the service technician initiates, among other things, device reset for activation and reset of the interceptor device.
    The reset device now guides the spindle holder carriage and the return lever connected with the spindle carriage, together with the retaining device to the activator, through a control circuit of the resetting device.
    The third position switch verifies that the restore device has left its rest position.
    As soon as the retaining device reaches the activator, the activator or the retaining nose arranged in the activator presses the retaining latch again back to the electromagnet in the meantime activated.
    It holds the retaining bar fixedly again and the second position switch is retracted.
    This switch position is at the same time the control command for the reset device to retract the spindle carriage, now together with the activator.
    In this case, the pressure accumulator is tensioned.
    As soon as the spindle carriage has reached its rest position, the third position switch is switched on again and the reset process ends.
    In the course of regular resetting, in this case also the first position switch or the safety switch is set back again.
    The interceptor device, together with the device for activating and restoring the interceptor device, is again ready for operation.
    If during this restoration a quick reaction of the intercepting device becomes necessary, regardless of the restoration progress, the intercepting device, by activating the electromagnets, can be quickly activated again.
    A—n—cE—— 11/30 If, on the other hand, the interceptor device in the attempt to reset + is still in the tightening position, the retaining latch would be broken on retraction of the return lever and the restoration would need to be initiates fabeseaaSE: re-started. . 5 In this case, it is visible that the return lever, together with the locking latch, due to the swivel shaft in common with the activator, a- : exactly follow the movement curve of the activator. This allows for exact positioning of the retaining device. In another configuration variant, the restoring device has a force limiting device, which decouples the holding device when a restoring force predetermined by the restoring device is exceeded. This can be appropriate when the displacement body is moved, for example, simultaneously with the activation of the restoration device. Thus, the intercepting wedges, which would then be frictionally pulled back from an intercepting position, would compress through the activator against the restoring device. In order to prevent overloading of the restoring device in this case, when a predetermined restoring force is exceeded, the holding device is uncoupled from the restoring device.
    In a configuration variant, the device has a mechanical lock, which makes it possible to lock the device in the ready position. This is of help since, during the assembly of an elevator installation, the devices of the elevator installation are not electrically connected. Locking allows for easy device mounting for interceptor device activation and restoration. In this case, preferably, when the mechanical lock is fitted, the first position sensor or the safety switch or the second position switch is forcibly stopped. With this, an unintentional start-up of the elevator installation without removing the mechanical lock is prevented. In a configuration variant, the device for activating and restoring an interceptor device is mounted in a housing, or
    Ea aaa Tavares aaa, 12/30 the housing is a component of the device. This housing is formed and - provided with connecting plates in such a way that the device can be attached to an interceptor device. As already mentioned initially, current intercepting devices are generally activated by means of a 5th lever mechanic, which is activated by a limiting cable. These interceptor devices generally comprise a lower connection point, which makes it possible to fasten guide shoes. The present molded house is now advantageously configured so that it can be attached to that connection point. The connecting plate is screwed together between the guide rail and the interceptor device. With that, the device for activation and . Restoration of the interceptor device can be attached to an existing elevator installation, or to an interceptor device. Therefore, it is exceptionally suitable for modernizing elevator installations. The device for activating and restoring the interceptor device interceptor device can be used in conjunction with an appropriate interceptor device in various configurations in elevator installations.
    In a configuration variant, a pair of intercepting devices with respective devices for activating and restoring the interceptor device is arranged above the cab. The devices for activating and restoring the intercepting devices are controlled by an electronic limiter and the restoring device is commanded by a brake control device. The electronic limiter controls, for example, directly or via the corresponding brake control device, the electromagnets of the devices for activating and restoring the intercepting devices. Electromagnets, as already described previously, are preferably connected in series.
    The electronic limiter can be, for example, a speed monitoring device, as used in WO 03004397, or it can be a monitoring device that evaluates a number of rotations of rollers, which roll over the cabin along the guide rails, or it can be a safety surveillance system as shown in EP1602610. The electronic limiter or the device
    corresponding sitivo is advantageously equipped with electric energy accumulators, such as batteries, accumulators, capacitor bank. With the help of these energy accumulators, in the event of a power failure in the building, the safety device is kept active for a predefined time É 5.
    : Naturally, instead of one pair of intercepting devices, several pairs of intercepting devices can also be attached to the cabin, with in each case corresponding devices for activating and restoring the intercepting device.
    In a complementary configuration variant, the counterweight is also equipped with one or several pairs of interceptor devices, with corresponding devices for activating and restoring the interceptor device. This is often necessary, especially in elevator installations with large lift heights. in transport or in elevator installations, j 15 in which other spaces are located below the elevator, such as basement spaces or garages.Electronic limiters, as shown in the cabin, are also possible on these counterweights.
    In a configuration variant, however, the counterweight does not have its own speed limiter, but the counterweight is controlled via a safety system via signal lines, which are integrated, for example, in a compensating cable. .
    In another configuration variant, the counterweight has its own electronic limiter and a brake control device for resetting the device for activating and resetting the interceptor device. The electronic limiter here comprises, for example, rollers, which are arranged on the counterweight and there roll along the guide rails of the counterweight. At least two rollers are equipped with speed sensors. The speed of the counterweight is determined by means of the two speed sensors, and if the speed is too high, the device for activating and restoring the interceptor device is activated, so that the counterweight is safely stopped.
    - AMNINCRNCEE———— 14/30 In this case, the counterweight can be supplied with power via- + the compensation cable and hold signals can be transmitted via a communication bus.
    The communication bus can be 0 - via a powerline connection or via a data line ê 5 of its own.
    A counterweight energy supply can of course also come from accumulators, which are fed, for example, by a generator, which can be integrated into the rollers, or which are recharged, in each case, in a nightly charge cycle.
    A reset command can be, for example, wireless. Likewise, E: also a hold signal from the interceptor device or from the device for activating and restoring the interceptor device can be transmitted wirelessly F.
    In another configuration variant, the counterweight is equipped with an interceptor device, — which is activated only in the event of an absent lifting force, by means of slack cable monitoring.
    In this case, only in the event of a lack of suspension force in the counterweight, which is the case, for example, in the case of a failure of a support means, the interceptor device in the counterweight is activated.
    To prevent an accidental reaction, for example as a result of cable swings, the slack cable monitoring is provided with a damping element such as a pneumatic damper or a reaction delay.
    A reaction delay is, for example, a path to be traversed by a slack cable activation, before an interceptor device is brought into activity.
    Paths of approximately 50 to 150mm are sufficient to sufficiently delay a slack cable activation in elevator installations with a travel speed of up to 1.6 m/s.
    A damping element, for example an oil damper, is advantageously configured to delay a reaction of the interceptor device by up to 0.5 seconds.
    An advantage of this variant is that an electrical connection of the counterweight is not required in the elevator installation and yet the counterweight is efficiently protected against falling.
    One
    NE ent e ee, 15/30 any wrong activation of the interceptor device on the counterweight, can be ————— inspected in-cab-or in the drive, since in the case of an area--= | tion of this interceptor device results in a strong sudden load change TE in the drive.
    In another configuration variant of an e-elevator installation, odi or the device for activating and restoring the interceptor device is additionally activated by a detection device, for checking an undesirable departure of an elevator car. from a stopped state. In a particularly simple embodiment of a detection device of this type, a drag wheel is compressed, if necessary, in a travel path of the elevator car. In normal operation, the drag wheel is distanced from the travel path, it is not F driven. The detection device comprises a sensor, which verifies a rotation of the drag wheel, when in the stationary state it is compressed by a certain rotation angle and which, when the predetermined rotation angle is exceeded, interrupts the circuit. for the device's electromagnets for activating and restoring the interceptor device. With this, the interceptor device is activated and further slipping of the elevator car is prevented.
    Combinations of the configuration variants shown for Counterweight and cab are naturally possible. Counterweights without any fall protection are naturally also possible when intercepting devices are only placed above the cab.
    In the following, the invention is explained by way of example by means of an example of a modality in connection with the figures.

    In the figures for equal operating parts the same reference signs are used over all figures.
    Fig. 1, together with Fig. 2, show a schematic elevator installation 1 in an overview.
    The elevator installation 1 is mounted in a building or in an elevator shaft 6 of the building, and it serves to transport people or goods within the building.
    The elevator installation 1 comprises an elevator car 2, which can move up and down along guide rails 10. The elevator car 2 is accessible from the building through doors.
    A drive 5 serves to drive and stop the elevator car 2. The drive 5 is arranged in the upper region of the elevator shaft 6 and the car 2 is connected with The drive 5 with support means 4, eg support cables or support straps.
    The support means 4 are guided over the drive 5, additionally up to a counterweight 3. The counterweight compensates for a — mass ratio of the elevator car 2, so that the drive mainly needs to compensate only for an imbalance between car 2 and counterweight 3. Drive 5 is arranged in the example in the upper region.
    outside the elevator shaft 6. Naturally, it could also be arranged elsewhere in the building, or in the region of cabin 2 or counterweight $a Drive 5 generally comprises a rotation number meter 51, which measures an actual number of revolutions of the drive machine n 5 and transmits it even to an elevator and drive control 50. The elevator and drive control 50 regulates and monitors the operation of the elevator, À controls the drive 5 and activates any devices of brake 52 of the drive unit 5. The elevator and drive control 50 is generally connected with the remaining control devices of the elevator installation via a communication bus. The lift and drive control 50 is generally connected with the cabin 2 with a suspension cable 48. Through this suspension cable 48 the cabin is supplied with - energy and the suspension cable 48 also comprises the necessary communication lines.
    The elevator and drive control 50 can naturally be realized with a housing. Several function groups of the elevator and drive control 50 can, however, be arranged in their own housings at different locations in the elevator installation.
    The elevator car 2 is equipped with an intercepting device 11, or in the example, with a pair of intercepting devices 11a, 11b, which is suitable for retaining and/or retarding the elevator car 2 in case of a movement unexpected, overspeeding, or at a stop. The interceptor device 11, 11a, 11b is arranged, in the example, below the cabin 2.
    The interceptor device 11 or each of the interceptor devices 11a, 11b is connected, in each case, with a device 14, 14a, 14b for activating and restoring the interceptor device. Devices 14, 14a, 14b for activating and resetting the interceptor device are connected with a brake control 46, which can activate the device 14, — 14a,14b for activating and resetting the interceptor device, for the purpose of activating the device interceptor 11, 11a, 11b and also for restoring the device 14, 14a, 14b. Brake control 46 comprises an electronic limiter or a corresponding speed sensor 57 or is connected and like the same.
    A mechanical speed limiter, as normally used, can be omitted because of this. The electronic limiter or the corresponding speed sensor 57 is realized as already described F 5 in the general part and is not explained here in more detail.
    The electronic limiter or the corresponding speed lord 574 of course, can be arranged directly on the cabin 2 or signals from the elevator control 50 can also be used. The device 14, 14a, 14b for activating and restoring the device interceptor and brake control 46 are connected in the example shown with an energy accumulator 44, with corresponding charging apparatus 45 and voltage transformer 59. Details of this configuration A are described in connection with Fig. 4. In the example shown in accordance with Figs. 1 and 2, also the counterweight 3 is equipped with interceptor devices 11g.
    They, in turn, are suitable for braking and/or slowing down counterweight 3 in the event of unexpected movement or excessive speed.
    The 11g interceptor device is also arranged in the example below counterweight 3. The counterweight is connected by means of a compensating cable 49with the cabin 2. compensating cables 49 are used, especially in larger buildings, to compensate for a weight of the support means 4, which moves during displacement of the cabin 2 and counterweight 3, relative to one another.
    In the present example, this compensation cable 49 comprises electrical lines, which, in turn, supply the necessary electrical energy and signals to the counterweight 3 or a 46g brake control disposed therein, an energy accumulator 449, as well as a device 45g load corresponding with 59b voltage transformer.
    The arrangement and operation of the interceptor device 11g, the device 14g for activating and restoring the interceptor device and corresponding parts substantially correspond to the modality described in cabin 2. Naturally, the interceptor device 11g also comprises in the counterweight 3 , in general, at least one pair of intercept devices.

    This sensor consists substantially in the fact that a rotation speed of rollers, for example of guide rollers, is realized.
    In this arrangement, no further safety-related data is required.
    Consequently, the compensating cable 49 does not need to transmit safety-related data.

    The elevator car or counterweight 3 is suspended on a support means 4 and is guided by means of guide skids 58along guide rails 10. Activation of the interceptor device is initiated by an electronic speed limiter eGB 57 via a brake control 46. In one embodiment, a speed sensor 57 is integrated in each case in at least two rollers.
    The rollers rotate along the guide rails corresponding to a displacement speed of the displacement body.
    An evaluation unit (not shown) compares the signals from the two revolution number sensors 57 to each other and determines the actual travel speed.
    When there is a check of non-conformity between the signals, an alarm is activated and the installation is stopped.
    When one or both signals from the two rotation number sensors 57 show too high a shift speed, the control circuit of the two devices 14 for activating and restoring the intercepting device is interrupted and the intercepting devices 11 are activated.
    Other modalities of the electronic speed limiter eEGB57 are possible, as described in the general part.
    The eGB57 speed limiter can be arranged on the cab or on the counterweight or in the engine room, or it is redundantly arranged in several locations. A power module43 makes available the power, advantageously at the same time, for the brake control, eventually the speed measurement and the operation of the restoration device. In general, it n 5 is supplied with energy through a suspension cable or a compensating cable.
    A Fig. 4 shows an exemplified layout of a wiring diagram of the interceptor device in an elevator installation. In pit 6, advantageously close to the drive, the elevator and drive control 50 is arranged. The elevator and drive control 50 comprises a safety circuit 42. This safety circuit 42 is interrupted when the elevator installation breaks down. finds j in a safety-relevant state, which is not compatible with normal travel. This state exists, for example, when an access door to the cabin is not closed correctly or when an emergency switch is activated, etc. In the event of an interruption of the safety circuit 42, in general, the drive of the elevator installation is stopped and a drive brake 52 is activated. The elevator and drive control 50 also generally has information about the operating speed of the drive, which is usually transmitted by a drive rotation number transmitter 51 to the elevator and drive control. - ment 50. The elevator and drive control50 is additionally connected, preferably via a communication bus 47 with the remaining elevator system and, of course, the elevator installation has an electrical power network 53.
    In cabin 2 there are several other electrical components, which are connected via suspension cable 48, for example via communication bus 47, but also via safety circuit 42 with elevator control and drive 50. These components, in addition to other parts necessary for operation, such as door control, lighting etc., are the brake control 46, in general, an electronic speed limiter 57k, a power module 43 and the device 14 to activate-
    It is tion and restoration of the interceptor device.
    o Device 14 for activating and restoring the > interceptor device is attached to the respective interceptor device and, if necessary, you can activate and restore it again. The device 14 for activating and restoring the interceptor device is activated by the brake control 46, for example, through a control circuit electromagnet 54, to activate the interceptor device 11 and to reset it again, for example. plo, through a reset device and control circuit 55. The device 14 for activating and resetting the interceptor device is preferably incorporated in the safety circuit 42. This causes, : in the case of device 14 for activating and resetting of the interceptor device, forcibly the safety circuit 42 is opened and the drive - of the elevator installation is stopped. Power module 43 supplies brake control 46 and preferably also device 14 for activating and restoring the interceptor device with power. In the example shown, the device 14 for activating and restoring the interceptor device is supplied with a voltage of 12V DC and the brake control 46 is supplied with a voltage of 24V DC. For this purpose, the energy module 43 has an energy accumulator 44, which in the example is connected via a charging device 45 to the energy network 53 and is charged by it. For the generation of different voltages, a 59 voltage transformer is provided in the example. This can be used for restoration, for example, usual products on the market, for example, in automobile construction, as there are 12V components there. are available —very advantageously. The counterweight 3, in the example according to Fig. 4, is also equipped with interceptor devices 119. The interceptor devices 116 are provided, in turn, with 14g devices for activating and restoring the interceptor devices and the counterweight it has its own 46g brake control and 43g power module, which are constructed substantially in the same way as explained in the example of cabin 2. Through a compensation cable 49, the power network 53 and the communication bus 47 are guided to counterweight 3. The safety circuit + 42 is not guided to counterweight 3 in this mode, but the security messages from the interceptor device 11g and from the device 149 for activating and restoring the interceptor device are processed in the control: 5 brake led and transmitted through the communication channel 47 to the E elevator control 50. In addition, in this mode the counterweight 3 has a first and a second speed sensor 57g, which measure a speed of displacement of the counterweight.
    On the counterweight the speed sensors are preferably embedded in rollers.
    The two 57g speed sensors can be monitored for coincidence and a safe speed signal can be + generated from there.
    Due to this safe speed signal, the brake control, upon checking the counterweight too high speed, may activate the 11g intercepting devices.
    Alternative arrangements and combinations are possible.
    Instead of the power grid on the counterweight, a trailed roller generator can charge the counterweight power accumulator 449 and, instead of the wired communication bus, a wireless communication bus can be used. .
    Therefore, the compensating cable 49 could be dispensed with.
    Fig. 5 shows interceptor device 11 with device 14 for activating and restoring the interceptor device.
    In the case of the interceptor device 11, this is, in the example, a simple action sliding interceptor device.
    Intercept wedges 12 are compressed upwards to an intercept position, if necessary, by device 14 for activating and restoring the intercepting device through an activator —17, by means of lever arms 20a, 20b, or until they break apart. touch the guide rail 10. Then, the movement of the mass to be braked or of the cabin 2 or of the counterweight and the friction between the intercepting wedge 12 and the rail 10 take care of the formation of a normal and braking force.
    To reset the interceptor device, the mass to be braked first needs to move upwards, so that the intercepting wedges 12 are released from their clamping position.
    Then, when the friction force between the intercepting wedge and the rail is sufficiently small,
    the intercepting wedge can be brought back down by the ——lever arms 20a, 20b through connecting splints 13, to a ready position.
    The device 14 for activating and restoring the interceptor device is screwed by means of a connection plate 16 with the p 5 sitivointerceptor 11. In the example, the interceptor device is activated from below.
    Alternatively, activation can also take place from above, because the device for activating and restoring the interceptor device pulls the intercept wedges, for activation, from above and then for restoration, compresses the intercept wedges back down.
    In the example, the interceptor device is still used in such fear that it stops a downward movement of the displacement body or the cabin or the counterweight.
    The device, together with the interceptor device, can also be used inversely, the device for activating and restoring the interceptor device maintains intercepting wedges in a superior position and service and, as necessary, moves them downwards , to stop an involuntary upward movement.
    In the example, an intercept device 11 with intercept wedges is shown.
    The device for activating and restoring the interceptor device shown naturally can also cooperate with a roller interceptor device, in which instead of intercepting wedges, intercepting rollers are activated.
    The use of eccentric interceptor devices is also possible, whereupon the eccentric is rotated by means of an activation rod by the device for activation and restoration of the interceptor device. | In Figs. 6 to 9 below, a structure and an operating flow of a device for activating and restoring the interceptor device is explained, in connection with the interceptor device shown in Fig. 5. Fig. 6 shows the activatable interceptor device 11 electrically, together with device 14 for activating and restoring the interceptor device in a ready position or in a normal position such as cutting.
    24/30! responds to the normal operation of the elevator installation. The device 14 for activating and restoring the interceptor device is attached, preferably screwed, by means of a connection plate 16 to the interceptor device 11. In the normal position shown, the intercepting wedges ii 5 12 are entirely underneath and horizontally are several millimeters away from the guide rail, so they cannot touch it at the offset of the displacement body (not shown). Intercepting wedges 12 are retained by activator 17, or by lever arm 20 integrated in activator 17, or by lever arms 20a, 20b integrated in activator 17 (see Fig. 5), by means of the connecting tab(s) 13 The ati- ; The valve 17 is rotatably mounted on the fence 15 about a swivel shaft and further has a control arm 22 which cooperates with a detent 23 and detent 27 with the electromagnet. A pressure accumulator 24, in the example designed as a pressure spring, also acts via a pressure axis 25 on the control arm 22 or on the activator 17 and makes available the necessary activation force, if necessary. sity, i.e., on release of the retaining nose 23, activate the interceptor device.
    The lever arm 20 is also preferably mounted via a vertical pivot 21 on the activator 17. This pivot allows for lateral compensation when the intercepting wedge 12 moves laterally on sliding up to the along a wedge bevel. Instead of the articulation, of course, the lever arm 20 itself can also be designed in a correspondingly elastic way, or the connecting flange 13 can be designed in such a way that lateral displacement is possible.
    In the views according to Figs. 6 to 9 only 1 lever arm 20 is visible in each case. But in connection with Fig. 5 it is clear that in each case two lever arms 20a, 20b are arranged next to each other, which activate the associated intercept wedges. Lever arms 20a, 20b are mounted via a central swivel body 19 to activator 17.
    In the example, the activator 17 is formed from several individual parts, such as swivel bodies 18, lever arms 20, 20a, 20b and control arm 22. Of course, the activator can also be formed in one piece, for example , as a casting in a mold. ã 5 In the example, a lever distance between connecting brace E 13 and swivel shaft 18 is selected large, compared to the control distance between push shaft 25 and swivel shaft 18. This lever ratio makes approximately 5 :1. In this way, the engagement paths on the pressure accumulator and control arm are shortened.
    This is advantageous since, with this, a quick activation of the ; interceptor device.
    In an example carried out, a necessary elevation of the intercepting wedges 12 is approximately 10 mm, until there is a tightening of the intercepting wedges on the guide rail.
    Due to the 5:1 multiplication, the lift on the pressure shaft is only approx. 20mm.
    With a pressure accumulator force of approximately 1000N up to 1400N, the mass of the two intersecting wedges, which in the example amounts to approximately 2 x 1.5 kg, can be moved within less than 0.1 second into position of intercept.
    By measures on the activator, which reduce the activator's mass, such as perforated levers or lever material made of aluminum or other lightweight yet resistant materials, this fast reaction time can be optimized.
    The pressure accumulator force setting, in this case, is selected in such a way that, for example, even when a pressure spring breaks - which equates to a loss of force of a spring turn - there is still sufficient residual force for activating the interceptor device.
    The electromagnet 28 is operated according to the quiescent current principle.
    That is, a holding force exists while the current is running.
    In this case, the electromagnet retains the retaining latch 27, which in turn, via the retaining nose 23, retains the control arm 22 and thereby the pressure accumulator 24. Thereby the activator 17 is fixed and the interception wedges 12 are retained through the lever 10 and the connecting tab

    13. This also prevents accidental activation of the + intercept wedges, eg by accidental contact with the guide rail. Furthermore, the position of the activator 17 is monitored by a first position sensor 38. 15 In one embodiment, the device 14, for activating and resetting the interceptor device, as still visible in Fig. 6, is provided with: a mounting lock 41. The mounting lock can be used for simple mounting to the housing, as shown in the dotted sketch and traced in Fig.6, and then retains the activator, preferably mechanically in position of readiness. With this, the device can be easily 'inserted into the connecting splints and mounted. This is helpful, as during assembly of the interceptor device or the device for activating and restoring the interceptor device, in general, electrical parts are not yet wired. In an advantageous embodiment, this mounting lock is coupled with the position sensor 38 to prevent an elevator installation with inserted mounting lock from being put into operation. After assembly of the device or after electrical connec- tion completed and command of device 14 for activation and restoration of the interceptor device, the assembly lock 41 can be removed and, for example, deposited in the housing with a retaining clip and the device 14 for activating and restoring the interceptor device is then held, as explained above, by the electromagnet 28 in the ready position. When then the flow of current in the electromagnet 28 is interrupted, for example, by the brake control 46 (see Figs. 1 to 4) or another safety device, then the magnetic force of the same disappears. The retaining latch 27 releases, as seen in Fig. 7, the retaining nose 25 of the control arm 22, or the activator, and the activating force of the pressure accumulator 24 now compresses the intercepting wedges 12 to up, to the intercept position. The displacement body or the elevator car or the counterweight is forcibly braked. At the same time with the activation of the intercepting wedges 12, the first position sensor is activated.
    38, whereby the safety circuit 42 of the lift installation (see = jFig4) is interrupted. Advantageously, there is arranged in the electromagnet 28 A second position sensor 39, for example a microswitch, which monitors the lock itself of detent 27. This second position sensor 39 : 5 can be used to early identify an accidental opening of the detent 27 or also to control a reset of the device 14 for activation and reset of the interceptor device, such as ex- applied below. In Figs. 7-9, the restoration or disengagement of the interceptor device is shown as an example. The device 14 for activating and restoring the interceptor device comprises for this purpose a return lever 31, on which the electromagnet 28 is arranged together with the air holding bar 27 and the second position sensor 39. The vise 31 is pivotally mounted on the pivot shaft 18 so that a pivot radius of the retaining nose 23 of the control arm 22 and the retaining latch 27 follow the same pivotal path. The return lever 30 comprises in the example a spindle carriage 35, which is connected with the return lever 31. The spindle carriage 35 is moved back and forth by means of a spindle shaft 35 by a drive of spindle 33. In addition, the reset device 30 comprises a third position sensor 40, again preferably a microswitch, which detects a retracted position of the spindle carriage 35 and thereby of the return lever 31 Before a restoration is then started, the displacement body has generally been moved back, in the opposite direction to the intercept direction. As a result, the intercepting wedges are released from their clamping position and they abut the guide rails substantially loosely, only required by the force of the pressure accumulator.
    24. After a braking of the displacement cup by interceptor device 11 and device 14 has occurred for activation and restoration of the correspondingly activated interceptor device, such as
    As shown in Fig.7, the spindle drive 33 - after an initialization by the FrrrreAAAeareAnn — brake control 46 (Fig. 4) - turns the feedback lever 31 on the spindle EEE shaft 34 and the spindle carrier carriage 35 downwards to the control lever 22, whereby the detent 27 is moved to the detent nose 23, such as 5 as shown in Fig.8. Upon reaching the detent nose 23, the detent nose 23 compresses the detent 27 back to the connected electromagnet 28, which now again retains the detent 27, as seen in Fig.9. This position is verified by the second position sensor 39. This is at the same time a control input to the brake control to reverse the travel direction of the spindle drive 33 and move the S spindle carriage 35 now, together with the control arm, to the ready position, correspondingly represented in Fig. 6. This position of a. readiness is achieved as soon as the third position sensor 40 is activated by the moved spindle carriage carriage, with which the reset is complete and the device 14 for activating and resetting the interceptor device is again in its ready position once that at the same time with the retraction of the control arm 22 naturally also the pressure accumulator 24 was tensioned again.
    It is visible that now, during a device return, in the event of a defective behavior of the displacement body, at any time the interceptor device can be activated again directly, by switching off the electromagnet 28. In addition, it should be noted that instead After spindle reset, of course also other drive types such as a linear motor or another rotary drive can be used.
    A spindle drive is advantageous as these spindle drives are often used for car windows and are correspondingly advantageous to purchase.
    Other advantageous additions are still visible in Figs 6a9. Thus, the spindle carriage 35, in one mode, is connected via a force limiter 36, for example a coupling spring 37 with the return lever.
    With this, an overload of the dis-
    restoration positive 30 when the displacement body itself during | = the restorative movement is moved, whereby through the wedges of MRS RRSRRARs 12 intercept an unexpected pressure force could act on the restorative device. The force limiter 36 limits the pressing force on the restoring device f 5 or the spindle shaft 34 to approximately 100 N. When the maximum value is exceeded, then the clamping lever can : move in idle running. To re-engage the clamping lever, the traction member is moved upwards.
    In addition, a shape of the retaining bar 27 is selected such that the retaining bar is opened again when, for example, the intercepting wedges 12, which remain fixedly tightened, prevent retraction of the same. In that case, by force of the reset device 30, the retaining latch can be opened again. As at this moment the second position sensor 39 also opens again or is activated, the brake control can identify this state and start the restoration again.
    Fig. 10 shows an advantageous connection of the electromagnets 28, in a typical use of two devices for activation and restoration and a pair of intercepting devices. In that case, as explained in Figs. 1 to 4, in each case a device for activating and restoring the interceptor device is connected with an interceptor device. The two electromagnets 28 are in this case connected in series and are supported by brake control 46 with a holding current. With this serial link, the two devices for activating and restoring the interceptor device are exactly electrically synchronized to milliseconds. The two intercepting devices to be activated are therefore activated at the same time.
    Simultaneously, with this, it is also ensured that in the event of an electrical interruption in a coil of the electromagnets 28, the two interceptors are activated and a harmful, unilateral interception cannot occur. Mechanical synchronization with a lever system is no longer necessary. In Fig. 11 a complementary or alternative modality to Fig. 1 or 3 of the safety concept of an elevator installation is represented — vador41. In that case, the elevator car 2 is equipped with devices = Eee interceptors 1 and corresponding devices 14 for activating and resetting the interceptor device with brake control 46, as previously described. Counterweight 3, in contrast to this, is equipped with a substantially known 11g interceptor device, which is activated by It is a slack cable 56 activation. This means that the 11g interceptor device is activated when a suspension force falls below a value previously adjusted for a predetermined period. Therefore, if the support means 4 in the elevator installation were to break, the device: elevator car interceptor would be activated through the brake control 46 and the elevator car would be braked safely and due to the "suddenly absent support force" in the support means, slack cable activation 56 would activate the counterweight interceptor device 11g and protect the counterweight3 against a fall. By means of a delay or damping device in slack cable activation 56, it is achieved that in one process of oscillation for a brief period there is no activation of the interceptor device 119.
    In the knowledge of the present invention, the elevator technician can modify the established forms and arrangements. For example, the brake control 46 and/or the power module 43 and/or the speed sensors 57 can be realized as separate sets or these sets can be brought together in a safety package. This safety package can also be a component of an elevator control. The device for activating and restoring the interceptor device may be attached as an assembly to an interceptor device, or it may also be mounted with an interceptor device, substantially in a housing.
