Line bracing tool

Abstract

The invention relates to a line bracing tool used for climbing overhead line during power maintenance. The line bracing tool is a lever mechanism mainly consisting of a main arm, a force bearing arm and a bracing rod, wherein a chute is formed on the side surface of the force bearing arm; the upper end of the force bearing arm is movably connected with the middle part of the main arm; a line slot is formed in one end of the main arm; a force arm adjusting ring is sheathed on the main arm; the lower end of the force arm adjusting ring is movably connected with the bracing rod; the other end of the bracing rod is embedded in the chute and can slide up and down in the chute. According to the technical scheme, the line bracing tool provided by the invention can be fixed on the top operation surface of an electric pole, and can hang a conductive wire stably in the air based on effort saving effect of the lever principle, thereby providing convenience for operators in winding aluminum armour tape and placing the wire in an insulator groove, reducing labor intensity, reducing operation risk, and improving work efficiency.

Description

technical field [0001] The invention relates to a wire support tool used for climbing high-altitude lines during electric power maintenance. Background technique [0002] With the continuous development of distribution network automation construction, companies have put forward higher and stricter requirements for power supply reliability. No power outages and less power outages have become a development trend. Our bureau has not yet carried out live distribution network operations. Therefore, innovations are being made to improve operating methods in order to make breakthroughs. Replacing insulators is a compulsory course in the daily distribution network maintenance work. The workload of replacing insulators is heavy, and the maintenance work takes a long time. Including the early survey site, pre-operation safety tools, personal protective equipment, labor tools, material preparation time, etc., It consumes a lot of manpower and material resources. Moreover, the replace...

Problems solved by technology

Analysis of the steps of replacing insulators shows that the most difficult steps in the whole process are the two steps of "carrying the wire on the shoulder and wrapping the aluminum tape" and "putting the wire into the insulator slot". Conductors and overhead insulated conductors (partially 120mm2, 185mm2, 240mm2), the diameter of the wire is thick and the weight is heavy. When the conductor is carried on the shoulder, the pressure on the shoulder is great. In addition, the operator must stick out the body when working at heights, and the safety belt is long. Offset, the foot buckle is relatively easy to slip, and the staff consumes a lot of physical strength. At this time, the risk factor is high and the work efficiency is also seriously affected.
