    1453112 Track levelling and tamping FRANZ PLASSER BAHNBAUMASCHINEN-INDUSTRIE GmbH 18 Jan 1974 [26 April 1973] 02434/74 Heading E1G A railway track is levelled and tamped, by application of vibration and pressure to the ballast on both longitudinal sides of the sleepers by crib tamping tools 8, the track being lifted during and/or before tamping, to the correct position as determined by a reference wire 5 and held under pressure against a stop device (not shown). For small connections the track is lifted solely by tamping but large connections are made by conventional lifting gear 12 either alone or in combination with tamping. A surface consolidator 14 and a sweeper plough for the ballast edges may be mounted to the rear of external tamping tools 9. The operation of the tamping tools 8, 9 lifting gear 12, and stop device (not shown) are controlled automatically by a central unit 18 connected to a detector 6 on the reference wire 5. The lifting gear 12 may be used as the stop device, and the track may be laterally aligned at the same time.

    ti in terms of additional cable chord and control unit
    Fig. 1 shows a tamping machine, a general EID; Fig 2 is the same, top view; FIG. 3 is a view of axonet-pvm tamping tools; Fig. 4 shows the control circuit of the vibro-drive and hydraulic cylinders of ballast compression; in fig. 5 - control unit diagram,
    The tamping machine comprises a frame 1 mounted on the undercarriage telephones 2 mounted on frame 1, system 3 off accounts including measuring trolleys 4 and cable-chord 5 connecting the trolleys 4, as well as tamping tools b and 7 mounted with the possibility of moving in the vertical plane from the hydraulic cylinder ,. The end points of system 3 are fixed with the possibility of permutation in height regardless of frame 1.
    To determine the position of the railway track relative to cable 5, sensors of position 8 in the profile are used, which can be made in the form of electric voltage dividers, or in the form of current dividers, or in the form of rotating coils, or in the form of potentiometers. Tools 6 are located perpendicularly to the longitudinal axis of the machine and are connected to the vibration actuator 9, and tools 7 are located between the tools 6 from the ends of the sleepers parallel to the longitudinal axis of the machine and connected to the vibration actuator 10,
    The transverse movement (ballast reduction) of each tool 6 and 7 is carried out by its own hydraulic cylinder. On frame 1, a track binder 11 is installed, driven by a hydraulic cylinder 12 and plows 13, the installation of which relative to frame 1 is adjustable both in the vertical and horizontal planes. The plows 13 are designed to feed rubble from the edge of the ballast layer to the ends of the sleepers. Sealing plates 14 fixed on the frame 1 are intended to seal the outer part of the ballast layer. The guiding bodies 15 of the track lifter C have their own reference system 16, the TOOR of the torus is connected through the sensor 17 to position the track in plan with the appropriate mechanisms, and also this system is connected with the vibration actuators 9 and 10 and the hydraulic cylinders of the transverse displacement of tools.
    The principle of operation of the machine is as follows.
    If the path is; in the field of tamping tools 6 and 7 directly on the uncorrected section of the error path shown in Figure 1 by dashed lines, the value of the measured value removed from sensor 8 has such an effect, as a result of which the contacts 18 are attracted to each other , in turn, cause the magnet magnet of the electromagnetic valves 19 and 20 to be attracted,
    By appropriately controlling the valve 19, the pipeline connecting the two cavities of the cylinder 12 is blocked, and the track bucket 11 is fixed in the desired position, with the result that it acts as a track position lock. Simultaneously at. help not shown on the valve figures is lowering the tools 6 and 7 and immersing them in the ballast. At the same time, due to the transposition of the valve 20, a pressure head comes in turn to the cylinders of lateral movement of the tools 6 and 7, which in turn comes from the tank 21. This supply of the named medium and, accordingly, the process of lateral movement of tools ends when so that he occupies a calculated position. Such an elevation of the path is advisable because even with a high pressure of ballast compaction under the sleeves, the displacement of the ballast layer in the direction of the slope is sufficiently reduced by installing tools 7. It is thus possible to withstand the desired optimal ballast compaction different states of the ballast layer.
    When the ballast-crushed stone under the sleepers is not yet sufficiently compacted, although the web already occupies the design position, the lateral movement of tools 6 and 7 can be carried out so long as to achieve the necessary degree of compaction. The elevator 11, which is blocked by the valve 19 and used as a fixing mechanism, as well as the movable frame 1, which is appropriately positioned relative to the tools 6 and 7, at the same time prevents the path from rising above the calculated position set by the system 3,.
    To compact the rubble under the sleepers, tools B and 7 are lowered by hydraulic cylinder 22, while tools 6 are immersed in ballast near the side and longitudinal sides of the sleepers, and tools 7 from the ends of the sleepers. Tools 6 and 7 are driven into vibratory motion by vibration actuators 9 and 10, containing, for example, eccentric shafts, as a result of which tools b and 7 vibrate in a vertical plane perpendicular to the longitudinal axis of the path. Ballast compression with tools b and 7 is performed using respectively hydraulic cylinders 23 and 24. As the ballast compressors, instead of hydraulic cylinders 23 and 24, screw mechanisms can be used. Pump 25 supercharges working
    medium (liquid) from tank 21 to vibration actuators 9 and 10 and hydraulic cylinders 23 and 24
    Through one of the respective electromagnetic hydraulic valves 26 or 27, the working medium is supplied to 5 control units 28, 29 and 30. Each of these blocks consists of a pressure reducing valve, a pressure measuring device or, respectively, a measured value sensor, and also a check valve. From the control unit of the working medium block 28, then the hydraulic cylinders 24 are facing into the cavities of the hydraulic cylinders 24, the working medium from the regulating block 29 is fed into both cavities facing the other two of the eight hydraulic cylinders most distant from the rail, and the working medium enters the from each other, the chambers of four immediately adjacent with rel-20 som hydraulic cylinders 23.
    The hydraulic cylinders, located directly at the rail, move the tools b, which are immersed in the area between the two processed cross ties. The hydraulic cylinders furthest from the rail serve as dL transverse movement of the tools b, which are directed towards each other and work in areas 30 located on both sides of the above-mentioned area between the two sleepers. The cavities of the hydraulic cylinders facing each other for the instruments b, which are loaded in the same gap between the sleepers, are connected to the pressure accumulator 31, which in turn, are turned from the rail of the hydraulic cylinders 24 to the pressure accumulator 32. These batteries respectively serve to return the instruments 6 and 7 to their initial resting position after the end of the transverse moving process. Since this can be done at a lower rate than the cross-room process itself, an additional pump 33 is used for this purpose, the capacity of which is less than that of pump 25.
    To operate the hydraulic cylinders 23 rotated from the railcars, 50 are powered by a pump 25, the supply medium of which is reduced by a corresponding degree when passing through the throttle 34. The working medium supplied by the pump 25 is supplied through control blocks 35, 36 to the zibrodrive 9 and 10 additionally .
    Regulatory units 28, 29, 30 and 35, 36 are implemented so that it is possible to carry out both the Q reduction of the amount of medium supplied to the drives and the reduction of its pressure. Each unit 28, 29, 30, and 35, 36 is supplied with a measured value sensor and, in particular, respectively. measuring gauge with an arrow
    device. These sensors can be made on the basis of a differential pressure meter or, respectively, a measuring instrument for the amount of working medium, as well as in the form of a pressure switch and a working medium flow, all of which are connected to switch instruments.
    The control of the pressure and quantity of the supply of the working medium is centralized from the control unit 37. Each of the aforementioned blocks 28, 29, 30, 35, 36, as well as the choke 34, is connected by its own control lines to the control block 37. Each of the respective measurement sensors feedbacks to the control unit 37 the current setting values of the supply quantity and the working medium pressure in order to facilitate the control and management of the operating personnel of the operation of the machine. Additional measuring sensors are also intended for this purpose. A control or accelerating element 38 is placed in the control line of the electromagnetic hydraulic valve 26, which is provided with an installation regulator and an appropriate control scale. Such a center control of all the actuators from block 37 allows for the quickest and most expedient simultaneous sequence of working processes, as well as providing universal binding of transverse displacement pressure or the number of revolutions of vibration drives to current operating conditions, and also, in particular, allows It is necessary to carry out an exposure of a uniform degree of compaction of ballast on extended sections of the path, regardless of the height of its rise.
    The scheme of the control block 37 serves to control the Separate bodies, in particular, tools b and 7 and the track-lift 11 (Fig. 5). The measured value removed from the sensor 8, working together with the reference system, is compared with the calculated value set by the adjustable resistance in the differential amplifier 39. Next, the obtained comparison value is applied to the threshold switch 40, the switching threshold of which can be set by its own control. Torah. According to the state of the switch of the threshold value, the contact 41 is worked out accordingly, which leads to the ready state the hydraulic cylinders 23, 24 or the track-lifter drive 11.

    If contact 41, controlled by a switch (KOMMYTaTOpot) 40, is in the lower position, in which the machine is ready for lifting, the switch is activated accordingly. which controls the connection of the forward additional conductor to the solenoid valve 42 in accordance with the set value of said difference, and mainly to the servo valve, which affects the lifting process mentioned earlier. The lifting process, as well as the transverse movement of the tools, is carried out only when the lowering switch 43 is triggered when lowering the tamping tools, which uses a conductive bus to pull the contacts of the relay 44, If both contacts of the relay are closed, then the corresponding position the switch 40 of contact 41 excites the magnet of the solenoid valve 42 or 45 so that the working medium supplied by the hydraulic pump is supplied to the drive of the track-lifter or and to the transverse displacement tools tools b or 7. If the error is less than the installation switching threshold or the corresponding permissible error, then the 41 after the threshold switch 40, 41, is in the upper extreme position and thus maintains the readiness of the tamping tools. If the error exceeds the set switching threshold, the contact 41 from its upper position goes to the lower one and thus attracts (closes) the contactTdB of the switch and thereby ensures readiness of the lifting operation. Following this, the path is lifted by means of a track lifter for the current difference values which is greater than the setup switching threshold, namely, between the final fixed difference value and the switching threshold, and starting from the threshold and inward s to the calculated value of the difference of the measured values is effected lifting path only through the tamping tools. In the path correction section, the difference value of the measured value is less than the set threshold, and therefore the path is lifted exclusively by tamping tools. With such small path elevations, it is also reasonable if a fixing device 46 for rails is provided in the area for placing the tamping group Hfcjx instruments , due to which it is possible to avoid sufficiently exceeding the path relative to the design position. The device 46 may, for example, be moved in height by means of two Cylinders relative to the movable frame of the machine. It also provides a circuit arrangement which ensures that the fixing device is permanently on the rail or is moving along it. Both chambers of each cylinder are connected by a pipeline through the intermediate connection of interlock assembly 47, which can be electromagnetically controlled. The magnet for triggering the lockout unit 47 is controlled by signals from the contact 41 connected to the threshold switch 40 if the path has reached the estimated position (the average location of the contact 41 is shown by a solid line). Due to this, it is possible to avoid exceeding the track relative to the design position when it is raised to insignificant heights. If the group of tamping tools is lifted, the relay contacts are opened and the lockout node 47 is also turned off. A part of the control unit circuit for ease of maintenance is assembled on a single board (in Fig. 5 it is shown in phantom lines), which can be very easily replaced when a defect is found in it. This board also has a switch with which it is possible to exclude (block) switch 40 and pin 41 from operation, i.e., carry out the previously known compaction process and lift the path, and during this process the path is lifted only by the track lifter, and not using tamping tools. It is also possible to set the controller 40 of the switch so that, if there is a path position violation greater than the threshold value, the path raises the track-lifter 11 to the design position and, with tamping tools, as before, compacted rubble. If the violation of the position of the path is less than the threshold value, then the rise, as has already been explained, is accomplished only by tampering with tools. To achieve a uniform and desired degree of compaction of the ballast and to control this value, a pressure gauge, such as a sensor 48 of measured value, which can work in conjunction with a dial gauge, is built into the central pressure pipe connected to the transverse displacement drives of the instruments. A pressure switch is connected to the pressure sensor 48, which, when the preselected maximum pressure reaches the system, triggers a relay, which in turn interrupts the direct current flow in the drive control circuit, i.e., displacement setters. Such a direct path of the electrical power supply bypasses the threshold switch 40 and the contact 41, as a result of which the compaction of rubble, even if the rails already occupy the design position, can continue until its maximum compaction in the location of the fixing device 46. The above switch in the sensor 48 in the simplest case , as shown, consists of a moving contact, which interacts with an arrow of a pressure gauge (contact pressure gauge). At the end of the tamping process, the tamping tools are lifted, a relay is triggered from the limit switch, as a result of which the movement drives, the track-picker 11 and the locking device 46 are interrupted. The machine then moves forward two sleepers, after which the work cycle is repeated again. In order to fully automate the workflow, in order for the maintenance staff to be freed from adjustment operations and can focus their attention on monitoring the operating current results, it is possible to connect the control unit to a software device or a storage 49 operating in analog or digital circuitry. Thus, it is possible to automatically control the amount of compaction of rubble, the duration and pressure of the transverse feed, as well as the frequency and amplitude of the vibration movement of the tamping tools depending on the measurement data transmitted through the feedback control devices and on the data corresponding to to rubble For the purpose of accumulating (storing) informational data for the aforementioned software device, both punched tapes and magnetic recording tapes or punched cards can be used. The railway line formed by the tamping machine is obtained with a more uniform compaction of the ballast and is more stable. In addition, the time interval between track repairs may increase.
