Device and method for monitoring wear degree of traction sheave

Abstract

The invention relates to the technical field of elevators, in particular to a device for monitoring the degree of wear of a traction wheel and a method thereof; for the device for monitoring the degree of wear of the traction wheel, the detection device is arranged below the traction wheel; the detection device includes a housing, a photoelectric device, and a light source With the convex lens, grooves and arc-shaped grooves are arranged alternately in the housing. The grooves correspond to the positions of the rope grooves respectively. There are two upper and lower chambers, and a light source is provided on one side of each group of shells; the present invention arranges a light source at one end of the traction wheel groove, and the light from the light source passes through the traction wheel rope groove to the other end, and a convex lens is arranged at the other end to transmit the light to the other end. After the light is focused, the light hits the photoelectric device. The electrical signal output by the photoelectric device changes with the intensity of the light. The wear of the traction wheel groove is determined by determining the electrical signal output by the photoelectric device in the upper and lower chambers of the housing. This arrangement has simple structure and strong applicability, and is suitable for further popularization and application.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a device and method for monitoring wear degree of a traction sheave. Background technique [0002] With the improvement of living standards, elevators have become an indispensable means of transportation for people to travel. During the use of the elevator, the steel wire rope is driven by the traction wheel to generate tension to drive the car to run. Due to prolonged use, the traction sheave grooves are subject to wear. The wear of the traction sheave groove will lead to insufficient traction force, causing failures such as sliding ladders and out of control, and in severe cases, it will lead to injury accidents such as topping, squatting and shearing. At present, the detection of elevator traction sheave grooves is judged by visual inspection, and real-time and long-term monitoring cannot be carried out. Contents of the invention [0003] The invention provides a device...
