The invention belongs to the technical field of mining shuttle car refitting, and aims to solve the problems that an existing electric control box is large in size and not beneficial to whole car arrangement, and high-frequency switching devices in the electric control box are concentrated, not beneficial to electromagnetic compatibility processing and low in reliability. The mining shuttle car frequency conversion traction system is characterized in that an electric signal processing module is arranged in an explosion-proof electric cabinet, three-phase alternating current directly or indirectly introduced by a shuttle car cable drum enters a main cavity through a wiring cavity in the explosion-proof electric cabinet and is connected with a switch, and the switch, an input reactor and a rectifier are sequentially connected; the rectifier is connected with the vehicle-mounted controller through a CAN bus; a direct-current power supply output by the rectifier is respectively introduced into a left traction inverter in the left traction explosion-proof motor box and a right traction inverter in the right traction explosion-proof motor box; and the vehicle-mounted controller is respectively connected with the left traction inverter and the right traction inverter through a CAN (Controller Area Network) bus. The device can reduce the volume of the explosion-proof electric cabinet, avoids the risk of cable extrusion, and improves the reliability of a traction system.
