[0002] In the field of power construction, climbing operations are an indispensable part. Their safety and efficiency directly affect the quality and progress of the project. When performing climbing operations, corresponding power construction climbing ladders are usually used. There are many types of power construction climbing ladders on the market. Most of the power construction climbing ladders are directly used insulating ladders. This type of insulating ladder is generally directly erected on the corresponding pole or wall, and then supported by manpower for workers to perform climbing operations.

[0003] The length of this type of directly used insulating ladder is constant, and there is a defect that the length cannot be adjusted according to needs. The constant length will take up more space when stored.

In addition, when setting up and using this type of insulating ladder, other personnel are needed to support it to ensure stability, which affects work efficiency. In view of this, we proposed an adjustable electric power construction climbing ladder. Utility Model Content
