Design and Application Research of Defect Detection System for Hoist Steel Wire Rope Based on TRIZ Theory
Aiming at the traditional defect detection method used for the steel wire rope of the downhole hoist in Gaozhuang Coal Industry,which has problems such as low detection efficiency,high labor intensity,easy occurrence of missed detections and so on,a mine hoist steel wire rope defect detection system is designed using TRIZ theory.This defect detection system mainly consists of a steel wire rope non-destructive testing instrument and memory,and a steel wire rope defect detection system management software.The defect recognition algorithm module and EMD in the management software can process the collected data,generate reconstructed LMA and LF waveform diagrams.The peak signal in the LMA diagram can accurately judge the broken wire position of the steel wire rope,and combined with the peak height in the reconstructed spectrum,the number of broken wires can be accurately determined.The practical application of the steel wire rope defect detection system in the hoist of Gaozhuang Coal Industry shows that this system can accurately judge and determine the position and quantity of broken wires in the steel wire rope.The detection time is short,the efficiency is high,and the degree of intelligence is high.It can effectively ensure the safe and stable operation of the hoist,and the economic and safety benefits are significant.
