In order to achieve efficient inspection of belt conveyor,a belt conveyor inspection system is constructed instead of manual inspection for the problems of long laying distance,poor working environment and small space of belt conveyor.The key sub-systems of the inspection system include the track system,the track support system,the robot body and the wireless communication system,etc.A high-strength aluminium alloy is used as the running track and fixed to the top of the roadway;the robot body is arranged with various types of detecting sensors,wireless communication,video acquisition,temperature acquisition devices,etc.,to realize the collection of environmental parameters along the running line and the running status of the belt conveyor;a wireless base station is arranged at intervals of 150 m inside the roadway,and a wireless base station is set up through the wireless communication system.A wireless base station is arranged in the roadway at intervals of 150 m.The wireless base station receives the inspection data of the robot body in real time and transmits it to the supercomputer to analyse the inspection data,so as to grasp the operation situation of the belt conveyor in real time.After the field application,the inspection system runs smoothly and can replace manual inspection,and the application effect is quite remarkable.
