Abstract

The utility model relates to a lifting mechanism of an elevator, which consists of a traction machine, a first traction rope, a second traction rope, an elevator car, a counterpoise and a supporting beam. The traction mechanism is arranged on the supporting beam. An output shaft is provided with a traction wheel. One end of the first traction rope and one end of the second traction rope are respectively connected with a rope hitch plate. The two rope hitch plates are fixed on the supporting beam. Four car guiding wheels are connected above the top surface of the elevator car. The four car guiding wheels are distributed in a rectangular way. The counterpoise is provided with two counterpoise guide wheels. A fixing guide wheel is fixed on the supporting beam. The other end starts from the rope hitch plate and is finally connected with the traction wheel after bypassing two adjacent guiding wheels of the elevator car, the fixing guide wheel and the rest two adjacent guide wheels of the elevator car. The other end of the second traction rope starts from the rope hitch plate and is finally connected with the traction wheel after bypassing a counterpoise guide wheel, the fixing guide wheel and the other counterpoise guide wheel. The lifting mechanism of the elevator can be driven with saved effort and eliminate the unbalance caused by the offset load of the elevator car.

Description

The lift system of elevator
Technical field:
The utility model relates to mechanical field, relates in particular to elevating gear, particularly a kind of lift system of elevator.
Background technology:
In the prior art, the car of elevator directly links to each other with hoist ropes one end, drives hoist ropes traction car up-and-down movement by traction motor, at car to be arranged with counterweight.Because car directly links to each other with hoist ropes, existing elevator drive mode is not laborsaving, simultaneously, can not overcome the overbalance that the car unbalance loading causes effectively.
Summary of the invention:
The purpose of this utility model provides a kind of lift system of elevator, and the lift system of described this elevator will solve the technical matters that elevator drive in the prior art is not laborsaving, can not effectively overcome the car unbalance loading.
The lift system of this elevator of the present utility model is by towing machine, first hoist ropes, second hoist ropes, car, counterweight and support beam constitute, described towing machine is arranged on the described support beam, be provided with output shaft in the towing machine, wherein, described output shaft is provided with traction sheave, one end of first hoist ropes is connected with one first rope hitch plate, one end of second hoist ropes is connected with one second rope hitch plate, described first rope hitch plate and second rope hitch plate are fixedly installed on the support beam respectively, the top face of described car is connected with four car track adjusting wheels, described four car track adjusting wheels are rectangular to be distributed on the end face of car, described counterweight is provided with two counterweight track adjusting wheels, be set with stator wheel on the support beam, the other end of first hoist ropes is walked around two adjacent car track adjusting wheels behind rope hitch plate, walk around stator wheel again, walk around remaining two adjacent car track adjusting wheels again, be connected with traction sheave at last, the other end of second hoist ropes is walked around a described counterweight track adjusting wheel behind rope hitch plate, walk around stator wheel again, walk around remaining counterweight track adjusting wheel again, be connected with traction sheave at last.
Further, the both sides of described car are provided with two main guide rails and four secondary guide rails.
Principle of work of the present utility model is: stator wheel is equivalent to fixed pulley; Car track adjusting wheel and counterweight track adjusting wheel are equivalent to movable pulley, form 1: 4 train so respectively.When towing machine drives car, laborsaving compared with conventional winding mode; Simultaneously, because the car track adjusting wheel is symmetrical arranged in car roof, can overcome the overbalance that the unbalance loading of car causes effectively.In addition, the car side is equipped with two main guide rails and four secondary guide rails, can effectively overcome the overbalance that the unbalance loading of car causes.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at the movable pulley wheel train structure in the lift system of elevator, by the winding mode of movable pulley train, can reach laborsaving driving effectively, simultaneously, be symmetrical arranged pulley by multiple spot, make cage operation more steady, the overbalance that the unbalance loading of elimination car causes.
Description of drawings:
Fig. 1 is the structural representation of the lift system of elevator of the present utility model.
Fig. 2 is the structural representation of the car in the lift system of elevator of the present utility model.
Fig. 3 is the structural representation of the counterweight in the lift system of elevator of the present utility model.
The specific embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, the lift system of elevator of the present utility model is by towing machine 2, first hoist ropes 13, second hoist ropes 15, car 6, counterweight 8 and support beam 4 constitute, described towing machine 2 is arranged on the described support beam 4, be provided with output shaft in the towing machine 2, wherein, described output shaft is provided with traction sheave 9, one end of first hoist ropes 13 is connected with one first rope hitch plate 10, one end of second hoist ropes 15 is connected with one second rope hitch plate 11, described first rope hitch plate 10 and second rope hitch plate 11 are fixedly installed on respectively on the support beam 4, the top face of described car 6 is connected with four car track adjusting wheels 7, described four car track adjusting wheels 7 are rectangular to be distributed on the end face of car 6, described counterweight 8 is provided with two counterweight track adjusting wheels 14, be set with stator wheel on the support beam 4, the other end of first hoist ropes 13 is walked around two adjacent car track adjusting wheels 7 behind rope hitch plate, walk around stator wheel again, walk around remaining two adjacent car track adjusting wheels 7 again, be connected with traction sheave 9 at last, the other end of second hoist ropes 15 is walked around a described counterweight track adjusting wheel 14 behind rope hitch plate, walk around stator wheel again, walk around remaining counterweight track adjusting wheel 14 again, be connected with traction sheave 9 at last.
Further, the both sides of described car 6 are provided with six roots of sensation guide rail 12, wherein take rail as the leading factor for two, and all the other four is secondary guide rail.
Concrete, towing machine 2 is connected with a control housing 1 by cable.
Be provided with the layer door 5 that matches with car 6 outlets in the building on the body of wall of every floor.
