Design and principle analysis of rebound wave detection device of steel wire rope of friction hoist
Friction elevator is a lifting device commonly used in vertical and inclined coal mines.It is the main device for lifting minerals,personnel and some mining machinery.The steel wire rope will be affected by various forces during long-term operation,resulting in complex rebound waves.The time difference of the rebound wave of the first rope can effectively reflect the condition of the steel wire rope.By detecting the time difference of the rebound wave of the first rope,defects in the steel wire rope can be discovered in advance.Eliminate safety hazards promptly.Based on this,developing a device that can accurately detect the rebound wave of the wire rope is of great significance to ensure the safe operation of the hoist.This article analyzes the elastic wave theory and vibration analysis of the friction elevator wire rope rebound wave,explains the design of the wire rope distance adjustment mechanism,self-locking decoupling mechanism and follow-up conversion mechanism,and demonstrates the efficient detection of the wire rope rebound wave by the mechanical structure of the device,aiming to improving the operational safety of friction hoists.
