[0002] In power system operation and maintenance work, climbing maintenance operation is a very common operation scene, for example, the operations such as maintenance, replacement of parts, line connection and the like of overhead lines, distribution boxes, transformers and the like power equipment all need the operation personnel to reach a certain height to be completed.

[0003] At present, in the power climbing maintenance operation, ladders (such as bamboo ladders, aluminum alloy ladders, telescopic ladders and the like) are generally used as the main climbing auxiliary tool in the industry. The ladder has simple structure, low cost and strong initial carrying convenience, and is widely used in various small and medium-sized power maintenance operation scenes.

[0004] However, when the existing ladder is used for power climbing maintenance operation, there are obvious technical defects, which are specifically as follows: when the maintenance operation needs to change the operation position, since the support range of the ladder is fixed, the operation personnel cannot directly move to the new operation position in the air, and must first safely evacuate from the ladder to the ground, then manually carry the ladder to the new target operation position and re-erect it, and then can climb to the corresponding height again to continue the operation.

[0005] The above operation process is not only cumbersome, but also greatly increases the labor intensity of the operation personnel, and also seriously prolongs the overall maintenance operation time and reduces the maintenance efficiency; at the same time, the process of climbing, evacuating the ladder and carrying the ladder multiple times also increases the safety risks such as falling and knocking of the operation personnel, especially in the outdoor uneven ground or the environment with large wind power in the air, the safety hazard is more prominent.
