Abstract

The invention discloses a traction system for an elevator. The traction system comprises a traction machine mounted in an elevator shaft, a traction steel wire rope and a counterweight filler weight arranged below the traction machine; the traction system is characterized in that one end of the traction steel wire rope is fixed to the inner wall of the elevator shaft, and the other end of the traction steel wire rope is fixed to the counterweight filler weight, a surface treatment mechanism is arranged between the counterweight filler weight and a driving wheel, and a surface treatment mechanism is arranged between a guide wheel of a lift car and the driving wheel; each surface treatment mechanism comprises a spraying mechanism used for spraying a wax layer on the surface of the traction steel wire rope and a wax removal mechanism used for removing the wax layer on the surface of the traction steel wire rope; the wax removal mechanisms and the spraying mechanisms are sequentially arranged in the length direction of the traction steel wire rope, and each wax removal mechanism is arranged between the corresponding spraying mechanism and the driving wheel; and according to the traction system for the elevator, on the basis of not affecting friction force between the traction steel wire rope and the driving wheel, the surface layer protection performance of the traction steel wire rope is improved.

Description

technical field

[0001] The invention relates to the technical field of elevators, in particular to a traction system for elevators. Background technique

[0002] The lifting process of the elevator is to wind the driving wheel of the traction machine, the guide wheel of the car and the counterweight wheel of the counterweight in sequence through the traction wire rope, so as to drive the movement of the car through the friction between the driving wheel and the traction wire rope. lift. As a special equipment, the safety of the elevator is directly related to the life safety of passengers. Therefore, the requirements for elevator repair and maintenance are high, that is, the frequency of maintenance is high, the service life of parts is short, and the replacement of vulnerable parts High frequency. And the elevator needs to lock the car and the counterweight during the maintenance process, so as to facilitate the loosening of the traction wire rope, and realize the inspect...

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] The invention provides a traction system for an elevator, which includes a traction machine 1 installed in the elevator shaft, a traction wire rope 2 and a counterweight 3 arranged under the traction machine 1, and is characterized in that: the traction wire rope One end of 2 is fixed to the inner wall of the elevator shaft, the other end of the traction wire rope 2 is fixed to the counterweight 3, and the middle part of the traction wire rope 2 is wound around the guide wheel 4.1 at the bottom of the car 4 and the center of the traction machine 1 in turn. On the driving wheel 1.1, surface treatment mechanisms for treating the surface of the traction wire rope 2 are provided between the counterweight 3 and the driving wheel 1.1 and between the guide wheel 4.1 of the car 4 and the driving wheel 1.1;
