Abstract: In order to improve the stability and synchronization of the left and right tracks of the mining EBZ220 roadheader, this paper expounds the working principle and load characteristics of the roadheader driving control system, analyzes the influencing factors of the roadheader driving deviation and the theoretical calculation of the deviation, designs the key technologies such as the electro-hydraulic synchronous driving control strategy based on the PID control algorithm, the wheel side speed measuring device and the intelligent driving system, and the test results show that, The average angular velocity of the left track of EBZ220 roadheader is 0.554rad/s, and the average angular velocity of the right track is 0.553rad/s. The driving synchronization of the left and right tracks is good, and the deviation meets the coal industry standard of the roadheader, which provides a reliable driving technical scheme for the development of intelligent and unmanned underground rapid tunneling.
