    The mechanism is for use on mobile structures for personnel operating high rise selving systems, to enable them to rescue themselves from the high position cabin in case of emergency. The roping-down mechanism is fitted to the upper edge of the operator's platform and consists of cable drum (22) with coils of cable (11) at the free end of which a suitable harness for the operator's descent is fitted. Inside the cable drum (22) one or two centrifugal force-action brake mechanism (21) are fitted. The drum is fitted to the shaft stub (17) by two hubs. Hub (23) is keyed-on to the shaft stub while a second hub is seated by bearing (18) to the stub. The keyed-on part of the drum has the brake drums (21) bolted to web (23) so that when the drum rotates pinion (25) travels along inside teething (20) of bearing-seated part of the drum. The rotating pinion drives two semi circular flyweights which expand to the action of centrifugal force and produce friction on the inner surface of the brake drum.

    The invention relates to a device for people descending on a rope, especially from the cabins of racking cranes, with which the drivers of such devices can self-descend D accident situations or at low speed to zero height,
    The constant increase in the height of the operation of the manually operated stacker cranes makes it necessary to increase safety equipment 1 and these devices in order to improve the protection of the workforce. With this, service personnel can leave the driver's cab in any position and from each height simply, quickly and reliably, 5 for example, if defects occur or when external hazards are present that directly threaten health or life. service personnel. Such situations may, for example, arise as a result of the pick-up device triggering and the cockpit jamming. in case of breakage of the lifting rope,. in case of defects in the drive of the lifting mechanism or in case of fires, leading to loss of power supply, etc.
    It is known that for emergency descent on rack cranes-stacker, ladders are necessary that go longitudinally along the lifting column and are either directly near the cab from the center point of the load S or can be reached on the back side of the lifting equipment only along special crossbars.
    However, all these forms of execution, proceeding from the width of the aisle of the racks, characterize the limited conditions of the location of the staircase with significant changes in the concept of the device or the most important functional units, for example, require off-center location of the lifting column
    From the rescue service, devices are known which, for example, are provided for lowering persons from the upper floors of a building in case of a fire hazard.
    According to the Federal Republic of Germany patent No. 1172122,. Кб.б1а-8/01, 1965. a similar rescue device has a rope drum 5 supported in a holder with a suspension device and having a braking device with

    bridge unwinding speed limit.
    The brake device consists of a gear pump, in which the circulation of fluid is closed in itself and is regulated externally by means of a throttle valve. Further, the cable drum acts on the friction brake, which is driven in the direction of the drum axis by a winding arrangement of the friction discs using a hydraulic cylinder, which in turn is connected with the circulation of the fluid of the gear pump. Initially, it showed itself from the negative side that with each failure of a gear pump and friction brakes do not function or only manually by means of a mechanical control device is brought into the ready state, as a result of which a valuable time is lost in a dangerous situation. As a drawback, the structure of this rescue device showed itself, on the basis of the friction brake
    and hydraulic brakes, and the need for complex manipulations under limited conditions in the cabins of rack cranes, which makes emergency descent impossible.
    A device for launching people’s rope, mainly from rack stacking cranes, is known, which has a gear rim rigidly connected to a base plate, meshed with at least one small gear wheel mounted by means of bearings on a cable drum with a converging rope and along i at least one centrifugal tor-, a braz, in the case of which an anchor plate with guy brake pads is placed (see German Patent No. 2528410, class A 62 B 1/08, 1977).
    The disadvantages of the known device Vlad Euts with its large size and low reliability.
    The purpose of the invention is to reduce the size of the device and increase its reliability.
    The object of the invention is to develop such a device for rope descent, the area consumed with a purely mechanical
    The construction is mainly determined by the dimensions of the drum collecting the ropes.
    According to the invention, this problem is solved in such a way that the attachment for the descent has one or several inner drum rotors and centrifugal brakes rotating with it. The centrifugal brakes on the housings are located in the already known form of one gear that drives the brake pads located inside the brake housings. All brake housings are fixed at the same distance from the axis of rotation of the cable drum, preferably in the area of the drum shell, in such a way that the gear wheel is located with a joint toothed rim in engagement in the direction of transmission. In this case, the ring gear is connected to the main plate and thus stands still, while the cable drum is located on its side movably on the stationary ring gear and fully or partially covered, the ring gear can have internal or external gearing.
    The brake pads are arranged in the form of semi-circular centrifugal bodies in pairs in the brake housing and, by means of springs, are pre-expanded, and the supporting parts of the FSs, respectively, at each end of the knee of the centrifugal body in the brake housing in the opposite position.
    On the reverse side of the centrifugal body is a brake pad, which operates in conjunction with the inner wall of the brake housing. The ability to adjust the prescribed descent rate on the rope results from the mutual agreement of the mass of the centrifugal bodies by their mass, as well as by the change in gear between the ring gear and the individual gears. At the same time, individual centrifugal brake discs with different gears can be hooked onto a fixed toothed crown.
    The process of descent on the rope begins by putting on the suspension along the descending person and hooking the end of the rope to the suspension along the su. After the person leaves the cabin rope.

    assembled on a drum, is wound51 under the weight of a person descending, and causes the rope drum to rotate. Together with the cable drum, centrifugal brakes rotate, gears running around the fixed ring and the brake shoes are set in motion. The brake pads are moved apart like centrifugal weights outside and lie down with their brake lining to the inner wall of the brake housing, as a result of which the speed of the gears and thus the number of revolutions of the rope drum is adjusted to the constant speed of descent on the rope, The advantage is 1; e- 1.5 m / s.
    Fig. 1 shows a rack crane, which is attached to the cabin of a device for people to descend on a rope; figure 2 - node I 5 figure 1; figure 3 - a device for descent on the rope, the section; FIG. 4 is a section A-A in FIG. 3 (rotated 90); on fig.Z - centrifugal brake; on figb - section BB in figure 5.
    The stacker crane is a floor-standing device and consists of a floor beam 1, a lifting support 2 with a vertically directed lifting trolley 3, which through a lifting rope 4 is connected to a lifting mechanism 5, which is located on the reverse side of the lifting support 2. Cab 6 at the free end of the lifting trolley 3, the staple Q of the lagging crane is attached so that the opening of the cabin is - facing the lifting trolley 3 and the one; from the amyn, the rear wall of the cabin lay with its un-displayed exit door opposite the lifting support 2.
    The descent device 7 is attached to the cab 6 in the area of the cab cover 8 to the side wall 9 so as not to limit the movement space of personnel 10 when operating the stacker edge of the racking edge. The rope 11 of the cable descent device passes through the guide roller 12 located outside the cabin b and is fixed by means of the earring 13 on the attachment point, executed in the form of a hook 14. The device itself has a rope drum 15, which accepts

    rope 11, which is opposite to the base plate 16, which serves to reinforce the adjustment.
    The support points 18 of the trunnion 17 are located on the fixed toothed rim 19, which has an internal engagement 20 and is connected to the base plate 16,
    Two centrifugal brakes 21 are attached approximately coaxially to the drum casing 22 with the drum base 23. In this case, the gears 25 on rolling bearings are located in the brake cases 24 and engage with the internal gear 20 with the gear ring 19. Each gear 25 drives the anchor plate 26, which closes the open side of each brake casing 24 and has supporting sections 27 of two brake pads 28, and these brake pads have a semicircular shape and each of them has a brake lining 29 on its reverse side. The pads 28 are hooked onto the support portions 27, respectively, with their ends of the semicircular knees, with the support portions 27 on the anchor plate 26 being exactly opposite to each other. The holes 30 at the other free ends of the semicircular brake pads 26 receive the spring 31, which is positioned freely and rests on the other brake pads with light preload so that the brake pads 28 in the quiescent state are previously moved apart and the brake lining 29 already is applied to the inner side 32 of the brake body 24. For re-unwinding of the rope 11 after the descent process has been performed on the rope, a shaped mold 33 located in the cab 6 is used, which is screwed in according to Drilling hole on the cable drum 15.
    The described cable rope descent device is not limited to rack cranes in its use. The field of application covers practically all areas of necessary self-rescue or the desired descent of personnel, where stairs, steps or the like are unavailable, or where the corresponding possibilities are not provided at all. It is advisable in this case the transportable design of the whole device for descent on a rope, i.e. the fixed attachment is replaced by a suspension device coaxially covering the rope drum 15 s (base plate).
