Method device for detecting diameter of rope groove of hoister

Abstract

The invention provides a method device for detecting diameter of a rope groove of a hoister. The method device comprises a bracket, a pedestal, a battery, a sensor main body, a sensor holder, a laser displacement sensor and the hoister. Through an arch height and chord length method, a position of a measurement device is adjusted, a projection point of the laser sensor at the rope groove is enabled to be at the lowest point of the rope groove, an initial measurement value of each rope groove is collected orderly, then, dynamic data is collected at different positions, shape errors of the rope grooves can be detected through monitoring on the data, the data is processed through matlab, and the processed data is substituted into a computational formula to solve the diameter of the rope groove.

Description

technical field [0001] The invention relates to a method for measuring a mine hoist, in particular to a method and device for detecting the diameter of a rope groove of a hoist. Background technique [0002] Since the sky wheel of the hoist is a large-diameter workpiece and most of the rope grooves are wrapped in the wire rope during operation, there is no good method for measuring the diameter of the rope grooves, and the error of the groove device during installation cannot be repaired by friction lifting. The machine uses multiple steel wire ropes to run at the same time. In order to ensure that multiple steel wire ropes can run synchronously, the difference between the bottom diameters of each rope groove should be as small as possible. If the difference between the bottom diameters of each rope groove is too large, the tension difference of each steel wire rope will become larger. When the hoist is running, the steel wire ropes in one group cannot run synchronously, whi...

[0002] Since the sky wheel of the hoist is a large-diameter workpiece and most of the rope grooves are wrapped in the wire rope during operation, there is no good method for measuring the diameter of the rope grooves, and the error of the groove device during installation cannot be repaired by friction lifting. The machine uses multiple steel wire ropes to run at the same time. In order to ensure that multiple steel wire ropes can run synchronously, the difference between the bottom diameters of each rope groove should be as small as possible.

If the difference between the bottom diameters of each rope groove is too large, the tension difference of each steel wire rope will become larger. When the hoist is running, the steel wire ropes in one group cannot run synchronously, which will cause relative sliding between the steel wire rope and the friction lining. At the same time, with the large vibration of the steel wire rope, the wear of the friction lining increases with use, which affects the service life of the steel wire rope
