Embodiment

[0029] In this embodiment, an elevator traction system, such as image 3 As shown, it includes a car 1, a counterweight 2, a traction machine, a traction wheel 3, a guide wheel and a traction rope 8, the traction wheel is installed on the traction machine shaft, and the traction machine is installed on the top of the hoistway.

[0030] There are two guide wheels, respectively the car guide wheel 4 and the counterweight guide wheel 5, and the car guide wheel and the counterweight guide wheel are respectively symmetrically arranged at lower positions on both sides of the traction sheave. The traction rope is wound on the traction sheave, and one end of the traction rope goes around the guide wheel of the car, then goes down the pulley on the top of the car, and then fixes it upwards on the top of the hoistway. The other end of the traction rope goes around the counterweight guide wheel and then goes down the pulley on the top of the counterweight, and then fixes it upwards on th...

Abstract

The invention relates to an elevator traction system which solves the problem that in the prior art, the diameter of a traction wheel is difficultly further reduced. The elevator traction system comprises a traction machine and guide wheels. A traction wheel is connected to a traction machine shaft. A traction rope winds the traction wheel and the guide wheels, the two ends of the traction rope are connected with an elevator car and a counter weight respectively, the two guide wheels are respectively the elevator car guide wheel and the counter weight guide wheel, the elevator car guide wheel and the counter weight guide wheel are symmetrically arranged below the two sides of the traction wheel, and the traction rope is of a band-shaped structure and composed of multiple rows of steel cores and nonmetal covering materials covering the steel cores. The elevator traction system has the advantages that the size of the traction wheel is reduced, torque is smaller, and therefore the size of the traction machine and the size of a brake device are smaller, the size is reduced, cost is lowered, energy is saved, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator traction system with small size, compact structure and low cost. Background technique [0002] The traction elevator is operated by traction rope, and its direct traction device mainly consists of traction rope, traction machine, guide wheel and other components. The layout of the traction device will not only directly affect the stress and life of the traction rope and the stability of the car operation, but also affect the stress, structural design and service life of the traction machine. [0003] At present, there are two types of layout methods commonly used for elevator traction and roping. One type uses guide wheels, such as figure 1 As shown, it includes car 1', car top wheel 2', suspension rope 3', main machine accessories 4', car rope head 5', traction machine 6', guide wheel 7', counterweight rope head 8', Counterweight wheel 9', counterweight device 10...
