Abstract

The invention discloses a device and a method for monitoring tensioning states of scraper conveyor chains and relates to the device and method for monitoring the tensioning states of scraper conveyor chains in coal mines. The device is characterized in that the device comprises scraper conveyor head and scraper conveyor tail motor power converters, chain suspension quantity transducers, scraper conveyor tail telescopic cylinder pressure sensors, signal conditioning units, primary fusion centers and a chain state display controller; the scraper conveyer head and tail are provided with the power converters respectively; the two telescopic cylinders disposed on the scraper conveyer tail in a parallel manner are provided with the pressure transducers respectively; and separation points of scraper conveyor head chain wheels and two chains are provided with the suspension quantity transducers. The signal conditioning units completes the preprocessing, such as amplification and filtering of the output signals of the transducers, the primary fusion centers perform primary processing of the transducer data of same types, the chain state display controller completes a second-step fusion of the chain tension characteristic information of different types and indicator lights show the chain tensioning states. The device and method improve accuracy and reliability of the monitoring, protect safety of the chains and accordingly prolong the service lifetimes of the chains.

Description

technical field [0001] The invention relates to a chain state monitoring device and method of an underground scraper conveyor in a coal mine, in particular to a chain tension state monitoring device and method of a scraper conveyor chain. Background technique [0002] The scraper conveyor is one of the key equipment in fully mechanized mining face. During the working process of the scraper conveyor, the chain tension will continue to change due to reasons such as unstable load and hydraulic support, resulting in the chain being either too loose or too tight. If the chain is too loose, the engagement between the sprocket and the chain will be destroyed, causing the chain to accumulate and kink; if the chain is too tight, it will increase power loss and cause excessive wear of components. Once the expansion and contraction of the chain exceeds the allowable range, it will seriously affect the life of the chain and the normal operation of the scraper conveyor. Therefore, the ...
