Design and application of frequency conversion automatic tensioning system for mining belt conveyor

The tensioning system is an integral part of the belt conveyor，and its performance will affect the operational reliability of the equipment.Taking the DSJ160/350/3×500 belt conveyor used in the coal mine working face as the research object，an automatic tensioning system was designed based on the advanced frequency conversion technology.The system mainly controls the travel of the tensioning trolley through the motor，tensioning roller，wire rope and pulley block.In the whole process，the tension sensor is used to detect the tension of the wire rope，and the result is transmitted to the controller for analysis in real time.The controller issues instructions to control the output voltage of the frequency converter，thereby controlling the output speed of the motor and achieving closed-loop control.The neural network fuzzy PID control technology is used，which has good performance.Engineering practice has shown that the variable frequency automatic tensioning system has achieved the expected effect and created good safety，social，and economic benefits.
