The invention relates to the technical field of tunnel engineering equipment, in particular to an electric traction device of a rail transport vehicle, which comprises a friction wheel electric driving device and a brake unit, and the friction wheel electric driving device and the brake unit are separately arranged; the friction wheel electric driving device comprises a main machine frame, a left driving frame and a right driving frame are hinged to the two sides of the main machine frame respectively, and motor speed reducers are installed on the left driving frame and the right driving frame. The friction wheel is connected with an output shaft of the motor speed reducer; the pre-tightening oil cylinder is installed on the main rack, and the two ends of the pre-tightening oil cylinder are hinged to the left driving frame and the right driving frame respectively; the guide wheel is mounted on the bottom side of the main rack; and the bearing wheels are mounted on two sides of the main frame. The motor speed reducer is adopted to drive the friction wheel, the rail transport vehicle is driven through the friction reaction force, and the higher energy utilization rate is achieved; meanwhile, a large number of hydraulic pipelines are avoided; modular design can be realized, and transportation tasks under different conditions can be completed through flexible combination; and the maintenance is convenient.
