Life prediction algorithm and life warning system for guide skid shoe of coal mining machine

Abstract

The invention relates to a life prediction algorithm and life warning system for a guide skid shoe of a coal mining machine. The algorithm includes: using a sensor to automatically measure a travelling distance of the coal mining machine, and accumulating the travelling distance to obtain a cumulative travelling distance; when the cumulative travelling distance reaches or exceeds a designed travelling distance of the coal mining machine, determining that the guide skid shoe of the coal mining machine reaches the life limit. The system comprises a rotary angle sensor component, an absolute value positional encoder and a data processing module; signal output ends of the rotary angle sensor component and the absolute value positional encoder are connected to the rocker rocking angle signal input end and travelling distance input end of the data processing module respectively, and connecting the warning signal output end of the data processing module to an electrical system of the coal mining machine. The algorithm and the system have the advantages that the life of a guide skid shoe can be intelligently predicted, the number of manual detections for the guide skid shoe is decreased, labor intensity is reduced, and secondary injury due to excessive wear of the guide skid shoe is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of excavating equipment, and relates to a life prediction method and an early warning system of a guide sliding shoe for a coal mining machine. Background technique [0002] my country has abundant coal reserves, and its coal output ranks first in the world. Coal shearers are increasingly developing towards intelligent and unmanned working faces. The guide shoe is installed in the traction and walking system of the shearer, which plays the role of guiding and fixing the meshing distance between the walking wheel and the pin row of the scraper machine. Due to the harsh working conditions of the shearer, the guide shoe is one of the weakest parts of the shearer’s walking system. At present, the life of the guide shoe is judged by manual inspection, which is difficult to detect and has high work intensity; Excessive wear and tear will greatly deteriorate the normal meshing of the shearer travel wheel and the ...

Due to the harsh working conditions of the shearer, the guide shoe is one of the weakest parts of the shearer’s walking system. At present, the life of the guide shoe is judged by manual inspection, which is difficult to detect and has high work intensity; Excessive wear and tear will greatly deteriorate the normal meshing of the shearer travel wheel and the scraper pin row, reduce the life of the travel wheel and pin row, and affect the reliability of the shearer and the operating rate of the mine
