Description

A kind of elevator traction sheave wear detection device and detection method

technical field

The invention belongs to the technical field of elevator detection equipment, and relates to an elevator traction sheave wear detection device and a detection method.

Background technique

The elevator is the main vertical transportation tool in the building. Its main structure is the connection between the car and the counterweight device through the traction wire rope. The traction wire rope is driven by the traction machine to control the operation of the elevator. The traction wire rope is wound on the traction sheave. The car is suspended at one end and the counterweight device is suspended at the other end. The friction between the traction wire rope and the traction sheave groove generates the driving force to drive the car to move up and down. With the rotation of the traction sheave, the pressure of the wire rope on the wheel groove is used The friction force generated by the relative movement between the wire rope and the wheel groove drives the elevator to run.

With the increase of the service life of the traction sheave groove, the sheave groove of the traction sheave will wear. With the increase of the amount of wear, the shape of the sheave groove will change, which will reduce the friction between the traction wire rope and the sheave groove and cause slippage. In case of accidents such as car and car accidents, according to relevant requirements, when the wheel grooves of the traction sheave are worn to a certain extent, the traction sheave needs to be repaired or replaced in time. security impact.
