Abstract
The invention discloses a traction device for an elevator. The traction device comprises a tractor, a guide wheel, a counterweight block, a car, a counterweight diversion sheave, a car diversion sheave, a steel wire rope and a rope pressing wheel, wherein the top of the counterweight block is connected with the counterweight diversion sheave through the steel wire rope; one end of the steel wire rope is fixed; after the steel wire rope is vertically downwards threaded through the counterweight diversion sheave, vertically upwards threaded through a traction wheel of the tractor, threaded through the rope pressing wheel and the guide wheel in sequence and vertically downwards threaded through the car diversion sheave, the steel wire rope is fixed; and the top of the car is connected with the car diversion sheave through the steel wire rope. The traction wheel of the tractor is above the horizontal plane of the guide wheel; the added rope pressing wheel enables a traction wrap angle to be increased to 180 degrees; the traction transmission is realized through enough frictional force; and the traction rope is prevented from slipping on the traction wheel when a no-load car upwards moves to an upper limit position and brakes urgently.
Description
Technical field
The present invention relates to a kind of drag device, particularly relate to a kind of drag device for elevator.
Background technology
The radical function of the drag device of elevator exports and transferring power, elevator is run, primarily of towing machine, traction steel-cable, track adjusting wheel and diversion sheave composition, in recent years, development due to Power Electronic Technique grows and raising that is progressive and people's living standard, the requirement of people to elevator is also more and more higher, the comfort level of elevator is also more paid close attention to safety, elevator is operated steadily safety, just need ensure elevator Installation and Debugging with there will not be traction deficiency to beat scooter or guide rail insufficient strength when checking and accepting to produce the problem that car shakes, the traction cornerite of the drag device of traditional elevator is maximum only can reach 160 ° can not ensure that unloaded car goes upward to the operating mode of the urgent stop of upper extreme position under, hoist ropes is non-slip on the traction sheave, also cause and there is no enough friction force to realize traction-driven, namely the load-carrying of elevator is little.
Summary of the invention
Object of the present invention is just to provide a kind of drag device for elevator to solve the problem.
In order to achieve the above object, present invention employs following technical scheme:
A kind of drag device for elevator, comprise towing machine, track adjusting wheel, to pouring weight, car, counterweight diversion sheave, car diversion sheave, steel rope and press rope wheel, described pouring weight top to be connected with described counterweight diversion sheave by described steel rope, one end of described steel rope is fixed, described steel rope is vertically downward after described counterweight diversion sheave, after traction sheave vertically upward past described towing machine, successively after described press rope wheel and described track adjusting wheel, fixing after described car diversion sheave vertically downward, the top of described car is connected with described car diversion sheave by described steel rope.
Particularly, described steel rope is after the traction sheave of described towing machine is downward, on described press rope wheel is backward, the traction sheave of described towing machine is on described track adjusting wheel horizontal surface, traction cornerite is 180 °, and described drag device adopts traction ratio to be the pulley combination of 2:1, and described towing machine is permanent-magnet synchronous toothless traction machine, the traction sheave of described towing machine is oppositely installed, described rearmounted to pouring weight.
Beneficial effect of the present invention is:
The present invention is a kind of drag device for elevator, the traction sheave of towing machine is on track adjusting wheel horizontal surface, the press rope wheel increased, traction cornerite is made to increase to 180 °, there are enough friction force to realize traction-driven, the load-carrying of elevator is increased, because in traction operation, the relative traction sheave of hoist ropes also exists microcosmic slippage, its andfrictional conditions is between static friction and dynamic friction, only be improved hoist ropes traction cornerite on the traction sheave and effectively could improve traction, Gu Yeyinjiao increase to 180 ° ensure that unloaded car goes upward to the operating mode of the urgent stop of upper extreme position under, hoist ropes is non-slip on the traction sheave.
