Research on automatic towing cable device control system of thin coal seam shearer

In the operation of the shearer in thin coal seam, because the cable follows the shearer back and forth for many times, it is easy to make the cable bend and superposition, which affects the service life of the cable and the life safety of the staff. The PID algorithm based on particle swarm optimization is adopted, and the PID control based on the speed and position is adopted. Combination of tension and torque parameters adjustment makes towing device control system can automatically adjust the parameters of the towing device, cable always maintain suitable tension state safety, improve the service life of machine cable, ensure the normal operation of the coal mining process, promote the fully mechanized working face less humanization, unmanned process, improve the degree of fully mechanized working face intelligent.
