Chain breaking, dislocation and chain falling comprehensive protection device of scraper conveyor

Abstract

The invention relates to an automatic monitoring comprehensive protection device of a scraper conveyor, in particular to a chain breaking, dislocation and chain falling comprehensive protection device of a scraper conveyor, which is applied to the field of coal mine machinery. Parallel chains are arranged on both sides of the scraper conveyor placed in parallel; scraping plates are uniformly and vertically arranged on each chain along the length direction of the chain; the chains are operated to a tail pulley from a head pulley of the scraper conveyor; a first proximity switch and a second proximity switch are arranged above the scraping plates; the first proximity switch and the second proximity switch are respectively connected with a monitoring device in parallel through signal wires in a heat shrinkage pipe. The comprehensive protection device disclosed by the invention has the advantages of high automation degree, little influence to the scraper conveyor and relatively wide application range and is simple and reliable.

Description

technical field [0001] The invention relates to a comprehensive protection device for automatic monitoring of scraper conveyors used in the field of coal mine machinery, in particular to a comprehensive protection device for chain breakage, wrong teeth and chain drop of scraper conveyors. Background technique [0002] The currently used scraper conveyor is mainly composed of cast stone tank, transmission device, head sprocket, scraper and circular chain. When the scraper conveyor is in normal operation, the transmission device provides power through the head sprocket. The scraper and the circular link chain are basically in a vertical state, and the circular link chain is connected in sequence to form an upper chain path, and the scraper runs smoothly on the upper chain path. [0003] Scraper machine is a kind of material conveying equipment commonly used in industrial and mining enterprises; when the conveying distance is not long (below 50 meters), coal preparation plants ...
