[0002] The operation of the power grid cannot be separated from the support of cables. As an important part of the power system, cables undertake tasks such as the transportation and distribution of electrical energy, and currently play a very important role in the networking of power cables.

[0003] After long-term operation, cable maintenance often reveals accidents such as damaged or broken outer insulation layers, and cable falls, leading to power outages for repairs. During maintenance, the cable needs to be supported. While existing technologies include cable lifting devices for maintenance, such as patent document CN215071459U, which discloses a temporary cable support device for power maintenance, the device includes a retractable sleeve rod with a tightening component on its outer side, a Y-shaped connecting rod on the retractable sleeve rod, and a clamping component on the outer side of the Y-shaped connecting rod.

The bidirectional telescopic rod 41 is started, and the lifting range is adjusted as needed. Then, the rotary motor 34 is started, which drives the pinion 37 to rotate, which in turn drives the rotating rod 32 to rotate, changing the lifting height. When the lifting height is insufficient, the lifting motor 25 is started, which drives the gear 24 to rotate, pushing the support rod 22 upward, which can further lift the cable, and the lifting height range is greater.
