Elevator traction system

Abstract

The invention provides an elevator traction system, and belongs to the technical field of elevators. The elevator traction system comprises a traction wheel, a brake, a traction rope, a diameter detection piece, a pressing block, an oil stain cleaning piece and a controller. According to the elevator traction system, the diameter detection piece detects the real-time diameter of the hoisting rope,the controller controls the brake to stop the traction wheel when the real-time diameter is smaller than the first preset diameter, the controller controls an oil stain dissolving agent injection structure to inject an oil stain dissolving agent into the traction rope located below a first containing groove, ultrasonic waves emitted by a second ultrasonic cleaning machine are used for cleaning oil stains on the traction rope, ultrasonic waves emitted by a first ultrasonic cleaning machine are used for cleaning oil stains on the traction rope, the controller controls the oil stain dissolving agent injection structure to inject the oil stain dissolving agent into the traction rope at a constant speed, and then the first ultrasonic cleaning machine or the second ultrasonic cleaning machine emits the ultrasonic waves to dissolve the oil stains in the oil stain dissolving agent, so that the oil stain cleaning effect is good.

Description

technical field [0001] The invention belongs to the technical field of elevators and relates to an elevator traction system. Background technique [0002] The steel wire rope is easy to be stained with dust during the rotation process. The accumulation of dust will form oil stains on the steel wire rope, which will increase the friction between the steel wire rope and the traction sheave, resulting in increased wear of the steel wire rope and affecting the normal operation of the elevator. [0003] Chinese patent CN 109850728A discloses a new type of elevator traction system, which relates to the field of elevators, including a traction wheel and a traction rope or a traction belt wound on the traction wheel, and also includes a At least one pressure loading assembly above the belt, the pressure loading assembly includes an arc-shaped support frame and an adjustable pressure plate assembly installed on the support frame, the adjustable pressure plate assembly includes an arc...

AI Technical Summary

Problems solved by technology

In the above-mentioned patent, if the steel wire rope is stained with oil, it will increase the friction force between the steel wire rope and the traction sheave. The friction of the pulley makes the friction between the wire rope and the traction sheave increase sharply. If it runs for a long time, it will affect the traction of the car and aggravate the wear of the wire rope.
