Maintenance of high voltage circuit ladder

Abstract

The invention relates to a high-voltage circuit overhauling ladder. According to the high-voltage circuit overhauling ladder, a lug seat is fixed on a supporting seat, a rotating pin is connected with the lug seat and a rotating seat, an angle between the supporting seat and the rotating seat is locked by a locking screw, an outer conical face of one supporting body is matched with an inner conical hole of the rotating seat or an inner conical face of an inner conical hole of a next supporting body so as to be fixed, and the corresponding inner conical face and the corresponding outer conical face, which are in fit, are automatically locked through enabling an annular locking groove in the corresponding inner conical face and a locking end of a corresponding right-angled rotator to be matched with each other after the corresponding inner conical hole and the corresponding outer conical face are fixed in a matched manner; folded type pedals which can be folded towards the connector end of each supporting body are fixed at the two sides of the surface of a columnar body of the corresponding supporting body, and an anti-slip adhesive is adhered to the bottom of the supporting seat. The high-voltage circuit overhauling ladder is simple in structure, very convenient to assemble and use and convenient to carry; during use, no tool is required during assembly and disassembly, and the difficult problems of upright climbing and standing for high-voltage line maintenance personnel during the maintenance of high-voltage lines are solved; during climbing, ladder assembling is high in speed and is safe and reliable, and the climbing is convenient; after use, disassembling, packaging and transporting are convenient.

Description

technical field [0001] The invention relates to an inspection and maintenance high-voltage circuit ladder used for upright climbing by maintenance personnel of high-voltage lines when maintaining high-voltage lines. Background technique [0002] Trees are planted near the transmission lines of high-voltage electricity. As the trees grow, their branches are very close to the high-voltage lines, sometimes even in contact with the high-voltage lines. It is necessary to manually trim the branches of the trees to protect the high-voltage lines; because there is no upright climbing to The height of the branches is a tool, and the way of high-voltage line maintenance personnel is to cut down the whole tree, which damages the green environment and is not conducive to environmental protection. When overhauling the high-voltage line, the maintenance personnel first climb up the utility pole, then climb up the high-voltage line, and stand or lie on the high-voltage line to check and fa...

Problems solved by technology

[0002] Trees are planted near the transmission lines of high-voltage electricity. As the trees grow, their branches are very close to the high-voltage lines, sometimes even in contact with the high-voltage lines. It is necessary to manually trim the branches of the trees to protect the high-voltage lines; because there is no upright climbing to The tool for the height of the branches, the practice of high-voltage line maintenance personnel is to cut down the whole tree, which damages the green environment and is not conducive to environmental protection

During the maintenance of high-voltage lines, the maintenance personnel first climb up the electric pole, then climb up the high-voltage line, stand or lie on the high-voltage line to check and fasten the connecting nuts, but the high-voltage line is unstable, often causing maintenance accidents
