The specific embodiment
Be further described below in conjunction with embodiment and accompanying drawing thereof:
Referring to accompanying drawing.Fig. 1,2 is depicted as embodiment of the present utility model.It comprises support 9, braking motor 1, retarder, protector, driving device, control setup, wherein driving device is made up of three tubular rope sheaves with the steel rope interlock, they are the inverted triangle shape, be installed on the support 9, one of the top left-hand is cage rope sheave 7, dextrad be counterweight rope sheave 6, be respectively equipped with the centrifugal governor 5 that safety guard-safeguard is used in the chamber of left and right sides rope sheave, 8, action direction is opposite, steel rope 10 external cage 11 orbiting of cage rope sheave 7, the external clump weight 12 of the steel rope of counterweight rope sheave 6 is along the inner track operation, and track is located on the raising legs; Braking motor 1 drives main horseline wheel 4 through cycloidal reducer 3, then again by the rope sheave work of the steel rope pulling left and right sides.The steel rope position of main horseline wheel hub outer wall is provided with disconnected rope inductor, is electrically connected by the contact and the control setup of wherein micro-switch 16.Disconnected rope inductor is made up of disconnected rope pressure-sensitive plate 13, micro-switch 16 and stage clip 14, and stage clip 14 roof pressures make it to be posted by steel wire rope loop at the back of disconnected rope pressure-sensitive plate 13.
Shown in Figure 2, be fixedly mounted on cage rope sheave 7 and counterweight rope sheave 6 on the support 9, the distance that its axle is 17 is arranged to regulate.By regulating the friction force that can classification changes between steel rope and the rope sheave.Be located at main horseline and take turns the mode of operation that the disconnected rope inductor of 4 belows is used to monitor steel rope on the rope sheave, and then the operation of control brake motor, carry out safety guard-safeguard.The spring at stage clip 14 places is regulated bolt 15 and is used for the elastic force of regulating stage clip.
During work, the support 9 at braking motor 1 place is fixing.Drive cycloidal reducer 3 by plunging joint 2, and work, under the interlock of steel rope 10, make cage 11 carry out descending operation through cage rope sheave 7 by the interlock of the output shaft in the same way main horseline wheel 4 of retarder.Counterweight rope sheave 6 and its clump weight 12 mating reactions simultaneously.Be cage when descending, steel rope is sent from the counterweight rope sheave, and clump weight 12 is up along track, otherwise instead then.Because steel rope is stroke limit up and down, accident of rushing to summit out of control can not take place in this towing machine.With the retarder accident cage to be fallen descending if braking motor takes place, then in the hypervelocity scope in the rope sheave of the left and right sides set centrifugal governor 5,9 act on immediately, its throwing piece will make it self-locking, can guarantee safety.Set steel rope 10 has adopted the mode of many set, all be provided with corresponding disconnected rope inductor on the next door of every steel rope, any steel cable ruptures, and all can cause disconnected rope pressure-sensitive plate 13 or driving lever action, promotes micro-switch, make its closing of contact, in time cut off general supply by control setup, braking motor in time brakes, and is out of service, thereby guarantee safety, wait for trouble-shooting then.
Motor power can adopt the frequency conversion low potential source, more steady, the safety of operation operation.This device is worked under the situation preferably in balance, drives easily, has almost eliminated noise.
Shown in Figure 3 is that this device is installed in scheme drawing on the dual-purpose building hoist pylon of the people's goods upper frame.As shown, pylon is provided with two cages 11, and this device 22 also correspondence has been established two covers, between them with the traction lifting of dangling of many steel ropes.
The single-piece building hoist is spliced by a plurality of standard knots 20, and as support cylinder and track, above ad hoc erecting stage 29 arranged, the cover 28 that climbs, the cover top of climbing are provided with the top that mounting or dismounting standard knot cylinder uses and stretch mechanism 25, rotary table 23, lifting barre 24, small winch 26, barre amplitude transformer 27 and suspension hook 21.This device 22 is placed on the climbing frame 28.Cage 11 is by the cylinder outside lifting of guide wheel 19 along standard knot 20, and the clump weight group is along the inboard operation of the cylinder of standard knot 20.Hang in the many steel ropes of cage, every all is provided with disconnected rope inductor 14.And be equipped with overload limiting device 18 and insurance steel chain 30 to make further safety guard-safeguard.The 31st, operator's compartment, operating personal is operated in operator's compartment.
This device is reaching comparatively ideal Expected Results with whole being equipped with in the trail run of the dual-purpose building hoist pylon of people's goods.
