Technical Field

[0001] The invention relates to the technical field of overhead line construction, in particular to an overhead line live line working insulated wire support frame. Background Art

[0002] In recent years, with the continuous development of live distribution network operation technology, the investment of various new equipment and new technologies has made new breakthroughs in various aspects of non-stop power supply operations, and live pole removal and erection construction is one of them. Due to the shortage of land resources in urban areas, urban distribution networks have adopted a large number of double-circuit or even multi-circuit distribution lines on the same pole. In addition, various communication lines are attached to the poles, resulting in the existing poles no longer having a place to install the down-to-house conductors, which brings great trouble to power construction. Therefore, it is necessary to erect new poles, increase the down-to-house line channels for users, and provide power to users in a timely manner. If the pole erection operation is carried out by power outage, it will have an adverse effect on the normal production and living electricity consumption of users, so it is necessary to implement live pole erection and dismantling operations. At present, the method used for live assembly and dismantling of pole towers is the live assembly and dismantling of straight poles by the insulated bucket truck and insulated gloves. After the operator uses an insulated rope to pull the wires to a safe distance, the pole tower is placed or lifted by an insulated bucket truck. However, there are the following problems when replacing, assembling or removing straight poles live:

[0003] 1. The wires and poles interfere with each other, the space is limited, and the safety distance is insufficient.

[0004] 2. People need to stay close to live wires for a long time to maintain a safe distance, which poses a great safety hazard.

[0005] 3. The current construction efficiency is low and the tower hoisting takes a long time. Summary of the invention
