Title:
SYSTEM AND METHOD FOR DETECTING FULL-LENGTH FLUCTUATION STATE OF SCRAPER CONVEYOR OF FULLY-MECHANIZED COAL MINING WORKING FACE
Document Type and Number:
WIPO Patent Application WO/2022/048215
Kind Code:
A1
Abstract:
A system and a method for detecting a full-length fluctuation state of a scraper conveyor of a fully-mechanized coal mining working face. The detection system consists of a hydraulic support base proximity switch triggering module (1), a single-section scraper conveyor posture control digital hydraulic cylinder displacement measurement module (2), a single-section scraper conveyor middle groove fluctuation angle calculation module (3), and a scraper conveyor full-length fluctuation state output module (4). The base proximity switch triggering module (1) detects an elevation angle of a hydraulic support push rod (501), the single-section scraper conveyor posture control digital hydraulic cylinder displacement measurement module (2) measures the amount of extension or retraction of a push rod of a scraper conveyor posture control hydraulic cylinder (201), the single-section scraper conveyor middle groove fluctuation angle calculation module (3) calculates a fluctuation angle of a single-section scraper conveyor middle groove (502); and finally, the scraper conveyor full-length fluctuation state output module (4) draws a full-length fluctuation curve of a scraper conveyor of a whole working face. The dynamic fluctuation change of a scraper conveyor in the vertical direction of a working face can be effectively monitored, providing a data foundation for subsequent adjustment of a fluctuation degree of the scraper conveyor.
