Description

Technical Field

[0001] The utility model belongs to the technical field of cable winding and unwinding equipment, and in particular relates to a cable drum anti-tangling wire mechanism. Background Art

[0002] The main function of the cable reel is to provide power output for the electric shovel during coal mining. One end of the cable reel is connected to the electric shovel, and the other end is connected to the high-voltage power supply point. The cable reel is equipped with two large rollers for winding high-voltage cables. The cable reel is a crawler chassis that relies on motor drive to meet the overall forward, backward and steering. During the movement of the electric shovel for coal mining, the cable reel can automatically retract and release the cable through the rotation of the rollers according to the actual needs of the electric shovel to ensure the normal power demand of the electric shovel.

[0003] In the past, when the cable reel was automatically unwinding, the cable's own weight and hardness caused a certain amount of resistance when dragged on the ground. The cable that had not been unwound on the drum would become loose or jump out of the drum, becoming entangled with other parts of the equipment, making it impossible to unwind the cable in time. In addition, the cable itself carried high voltage electricity, which posed a great safety hazard to equipment and personnel. Utility Model Content
