The utility model belongs to the technical field of overhead rail type locomotives, and aims to solve the problems that an overhead rail is easy to vibrate and
batch production and standardized use cannot be realized in the existing crane driving process. According to the
monorail hoist driving device, a flexible conveying belt is installed under a hanger rail and laid in the length direction of the hanger rail, a mounting frame is arranged on a transverse frame plate of a hoist frame, and the flexible conveying belt penetrates through the mounting frame; the driving motor is installed on the installation frame, the driving wheel is connected to the driving end of the driving motor, and the wheel face of the driving wheel is in attached transmission with the side face of the flexible conveying belt. The clamping adjusting
assembly is arranged on the mounting frame, the wheel face of the clamping wheel is attached to the side face of the flexible conveying belt, the driving wheel and the clamping wheel are located on the two sides of the flexible conveying belt respectively, and the distance between the wheel face of the clamping wheel and the flexible conveying belt is adjusted through the clamping adjusting
assembly. The lifting rail vibration caused by direct action on the lifting rail is avoided, and the device is suitable for
monorail hoists under different working conditions.
