The invention particularly relates to a remote control stepless frequency conversion speed regulation traction device. A motor, a reduction gearbox and a roller part are arranged on a base; the motorprovides power for the traction device; the motor is a stepless speed-regulating variable-frequency motor and is connected with a variable-frequency speed regulator; the reduction gearbox comprises ahard tooth surface gear; the reduction gearbox can realize mechanical speed change; the high speed and the low speed can be achieved, and the speed ratio is about two times; the reduction gearbox is connected with an output shaft of the motor through a coupler; the roller part consists of a pinion shaft, a gearwheel, a main shaft, a rope winding drum and a rope lining; the rope winding drum is connected with the coupler through the pinion shaft, the gearwheel and the main shaft; and a braking device comprises an electric hydraulic push rod and a manual belt type braking device. The variable frequency motor is adopted to control the speed of the roller, and the speed of the device is controlled through variable frequency speed regulation control, so that smooth start and stop of the deviceand linear control of the speed of the device can be realized.
