One side of the contiguous suspension rope of cab described in the portable traction elevator of above-mentioned band symmetry assembly pulley also is provided with wire holder, to guarantee safe in operation.
The adjustable spring device can be adopted in the support end of band shock absorber, the tension side of belt tension device described in the portable traction elevator of above-mentioned band symmetry assembly pulley.
The utility model compared with prior art has following advantage;
1. can realize not having the machine room counterweightless arranges, neither need large-scale machine room and reel to come the rolling steel rope, do not need to dispose counterweight yet and just can realize traction, thereby can more spacious elevator cage be installed in same hoistway area, the arrangement of its gangway and cab moulding are also more flexible and changeable.
2. integral structure is simpler, compact, adapts to high-lift application especially.
3. engine installation and control setup and vehicle are linked to be an integral body, and its preceence is that all control paths are concentrated and need not be stretched out, and are equivalent to machine room at the bottom of sedan-chair top or the sedan-chair, and operation, maintenance and emergency relief are more convenient; Be convenient to realize the batch manufacturing of Detroit automation, thereby reduce production costs; A large amount of quality control work can be finished before dispatching from the factory, to guarantee running quality; Be convenient to realize no frame construction, reduce on-the-spot installation workload and construction time; Propulsion source is followed vehicle and is moved, and can adopt the type of drive of similar automobile or battery-driven car.
4. need not drop-gear box and just can realize high step-down ratio, the convenient lightweight motor of miniwatt that adopts.
5. the situation that up hypervelocity can not occur need only adopt electric or mechanical stop prevents surpassed distance.
6. between suspension rope and the cab relative motion is arranged, adopt wire holder can realize braking and increase safety assurance.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
Embodiment 1
As shown in Figure 1, the portable traction elevator of the symmetrical assembly pulley of band of the present utility model, comprise cab 1, suspension rope 2, be provided with a main traction pulley 4 that drives of band actuating device at cab 1 top, be provided with a pulley 3 in cab 1 bottom relatively symmetrically with the main traction pulley 4 that drives, also be respectively equipped with a corresponding leading sheave 5 in well headroom and bottom; The upper end of described suspension rope 2 is connected with the support end 6 of the band shock absorber that is arranged on well headroom, and suspension rope 2 is walked around the main leading sheave 5 of traction pulley 4, well headroom, the leading sheave 5 of hoistway bottom, pulley 3 backs of cab 1 bottom of driving successively and is connected the tension side 7 of the belt tension device bottom being arranged on hoistway downwards; Be provided with the main control setup 8 that drives 4 runnings of traction pulley and stop of control at cab 1 top; When main traction pulley 4 driving or the glancing impacts that drive, connected cab 1 overcomes gravity by suspension rope 2 and the main friction force that drives between the traction pulley 4, thereby can controllably rise, descends or stop; The support end 6 of band shock absorber, the tension side 7 of belt tension device are the adjustable spring device.
