Traction wheel wear monitoring device and method thereof

Abstract

The invention relates to the technical field of an elevator, and in particular relates to a traction wheel wear monitoring device and a method thereof. The traction wheel wear monitoring device is arranged under a traction wheel and comprises shells, photoelectric devices, light sources and a convex lens. Grooves and arc-shaped grooves are alternately formed in the shells, the grooves respectivelycorrespond to the position of rope grooves, and the arc-shaped grooves are matched with an outer ring of the traction wheel. A division plate is transversely arranged in each groove, and the groove is divided into an upper chamber and a lower chamber by the division plate. The light sources are arranged on one side of each group of shells. The light sources are arranged at one end of a traction wheel groove, and the light of the light sources penetrates through the rope grooves of the traction wheel to the other end. The convex lens is arranged at the other end. After the penetrated light isfocused, the light is shined on the photoelectric devices. Electrical signals output by the photoelectric devices vary with the intensity of the light. The wear of the traction wheel groove is determined by determining the Electrical signals output by the photoelectric devices in the upper and lower chambers of the shells. The traction wheel wear monitoring device has a simple structure and strongapplicability 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...
