Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1 , the present invention provides a technical solution: a cable rack for power cable maintenance, comprising a base 1 , a first groove 2 is formed on the right side of the upper surface of the base 1 , and the bottom surface of the first groove 2 is on the left side A stepper motor 3 is fixedly connected, the output end of the stepper motor 3 is fixedly connected with a driving gear 4, the left side of the upper surface of the base 1 is fixedly connected with a fixed seat 5, and the right side of the fixed seat 5 is rotatably connected with a lead screw 6, The left side of the surface of the lead screw 6 is fixedly sleeved with a driven gear 7, and the driven gear 7 is meshed with the driving gear 4. The right end of the surface of the lead screw 6 is screwed with a nut 8, and the upper surface of the nut 8 is hinged with a connecting rod 9. At one end, a fixed rod 10 is fixedly connected to the upper surface of the fixed seat 5 , a sliding ring 11 is slidably sleeved on the surface of the fixed rod 10 , and the lower part of the right side of the sliding ring 11 is hinged with the other end of the connecting rod 9 , the sliding ring 11 A fixing claw 12 is fixedly connected to the right side of the upper surface of the upper surface, the inner side surface of the fixing claw 12 is laterally connected with a first rotating shaft 13, and the surface of the first rotating shaft 13 is fixedly sleeved with a supporting wheel 14.

The stepping motor 4 is electrically connected to an external power source.

The fixing claw 12 is arranged on the right side of the upper surface of the sliding ring 11 to prevent the weight of the cable from tipping the device to the left when the support wheel 14 supports the cable, thereby injuring the user.

Specifically, in order to reduce the frictional force between the sliding ring 11 and the fixing rod 10 when the sliding ring 11 slides on the fixing rod 10 , the left and right sides of the inner ring surface of the sliding ring 11 are provided with second grooves 15 .
