Description

Technical Field

[0001] The utility model belongs to the technical field of cable winding and unwinding equipment, and in particular relates to an automatic cable arrangement mechanism for an electric shovel. 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. Two large rollers are installed on the cable reel 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. The automatic cable arrangement mechanism of the electric shovel is one of the important parts of the cable reel. If the left and right lateral movement speed of the cable arrangement mechanism cannot match the rotation speed of the cable roller, it will cause the cable to twist and deform and the cable to be tangled, which will directly affect the working efficiency of the electric shovel for coal mining.
