[0002] In the prior art, cable winding drums are widely used in fields such as mining and fire fighting that require long-distance power supply. The existing cable winding drums are generally composed of a drum frame, a drum spindle and a cable. The cable on the drum spindle is pulled and the drum spindle is rotated to achieve long-distance cable delivery. With such a structural design, when the pulling end stops, the drum spindle will continue to feed the cable forward due to physical inertia, so that the cable on the cable winding drum is easily scattered or disrupted due to the physical inertia of the drum spindle, and the long-distance and stable cable delivery cannot be achieved, and the practicality is poor.

[0003] Regarding the problem in the related art that when the cable winding reel is used to draw power over a long distance, the cables on the cable winding reel are easily scattered or disrupted due to the physical inertia generated when the main shaft of the cable winding reel rotates, there is still a lack of a better technical solution. Utility Model Content

[0012] In one of the embodiments, a handle is further included, and the handle is installed on the winding rotation shaft on a side close to the brake device.

[0013] The beneficial effect of the utility model is that by adopting the structural design of adding a brake device between the winding drum frame and the winding drum main shaft, it is effectively prevented that after the cable pulling end stops pulling, the cable wound on the winding drum main shaft continues to be fed forward due to the physical inertia of the winding drum main shaft, thereby causing the cable wound on the winding drum main shaft to spread out or be disrupted, thereby realizing the function of long-distance and stable wire feeding. Specifically, the brake part, brake pad and brake wheel cooperate with each other, so that during the rotation of the brake wheel, the brake part controls the brake pad to give the brake wheel a certain resistance, thereby playing a damping and buffering role on the one-way bearing and the winding drum main shaft, so that the winding drum main shaft can rotate smoothly to feed the wire, and the utility model is highly practical.
