The aim was to design a variable frequency tensioning device suitable for long-distance conveyor belt,and analyze its structure,tensioning process,and control methods.This device integrated high-precision tension sensors and advanced frequency conversion regulation technology to achieve real-time and precise control of conveyor belt tension.In the practical application of the 2100 transportation roadway in Shanxi Lanhua Qinyu Coal Mine,the variable frequency tensioning device showed excellent stability,effectively solving the problems of conveyor belt slippage and heavy load starting difficulties during the starting process.At the same time,it maintained the tension force within the optimal range during normal operation,reducing equipment wear and energy consumption.This study improves the operational efficiency and safety of belt conveyors,providing valuable technical references for the intelligent automation level of coal mine conveying systems.
