Abstract
A frictional force monitoring system for middle troughs of a scraper conveyor, comprising a scraper conveyor system and a sensing detection system. The scraper conveyor system consists of a machine body, middle troughs, thrust lugs, scrapers, a double chain, a sprocket, a speed reducer, an electric motor and a frequency converter. The sensing monitoring system consists of force receiving modules, a three-dimensional force sensor, and a pre-embedded temperature sensor. The frictional force monitoring system is able to monitor impact loads, frictional forces, friction coefficients, temperature, etc. between an annular chain, coal bulk, and middle troughs of the scraper conveyor under complex and severe operating conditions, and to provide the technical means for the design, safety early-warning and health evaluation of the scraper conveyor, and can provide a data basis for studying friction wear and fatigue breaking mechanism of middle troughs of a scraper machine.
