Rope climbing device capable of slowly descending in case of power failure

The utility model discloses a rope climbing device capable of slowly descending after power failure, and relates to the field of lifting devices. Under the condition of power failure or failure, an existing rope climbing machine cannot control slow descending of equipment such as a hanging basket, and particularly when a person is hung at the high altitude, potential safety hazards exist. The reduction gearbox is located on the left side of the main power box, the guide wheel box is located on the left side of the reduction gearbox, a rope guide wheel is arranged in the guide wheel box, a motor system and a battery are arranged in the main power box, and the motor system comprises a motor and a two-stage planetary gear reduction device driven by the motor. An output shaft of the secondary planetary gear speed reducer is connected with a driving pinion, the driving pinion is meshed with a driven gear wheel and drives a rope guide wheel through a driven center shaft, the driven center shaft of the driven gear w
