Abstract
The invention discloses a system and a method for detecting a full-length fluctuation state of a scraper conveyor in a fully-mechanized coal mining working face. The detection system consists of a proximity switch trigger module of the hydraulic support base, a displacement detection module of the digital oil cylinder for position and attitude regulation of the single-section scraper conveyor, a calculation module for the fluctuation angle of the middle groove of the single-section scraper conveyor and a full-length fluctuation state output module of the scraper conveyor. Detect the elevation angle α of the push rod of the hydraulic support through the proximity switch trigger module of the hydraulic support base, detect the telescopic amount of the piston rod of the digital oil cylinder for position and attitude regulation of the single-section scraper conveyor through the displacement detection module of the digital oil cylinder for position and attitude regulation of the single-section scraper conveyor, the calculation module for the fluctuation angle of the middle groove of the single-section scraper conveyor calculates a fluctuation angle of the middle groove of the single-section scraper conveyor; and finally, the output module of the full-length fluctuation state of the scraper conveyor draws a full-length fluctuation curve of the scraper conveyor of the entire 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.
