Abstract：In view of problem of cable and cable traction clamp damaged by tension overloading of cable traction of shearer,a cable traction tension overload protection device of shearer was designed.The device adopts tension sensor to gather traction force signal produced in process of tracting cable by shearer,intelligent control circuit of microcomputer determines traction tension of cable of the shearer whether is overload or not through software analysis.If traction tension of the cable is overload,the microcomputer automatically controls reverse traction of the shearer,and reduces cable traction tension of the shearer to the lowest,and sends out a voice warning.The actual application verifies feasibility of the device.
