Electric power maintenance ladder

Abstract

An electric power maintenance ladder is disclosed. A connecting base is fixed on a fixed seat of the electric power maintenance ladder. A connecting shaft passes through a pin hole in the connecting base and a pin hole in the lower part of a bearing seat so as to connect the connecting base and the bearing seat together. An inner conical hole matches an outer conical surface, and an inner conical surface and the outer conical surface which fit well with each other are automatically locked through cooperation between a brake slot and a brake head. A gravity cone is installed on the bearing seat. A pedal is fixed on each ladder pillar. The electric power maintenance vertical ladder has a concise structure and is very convenient to manufacture, install and use. Upright climbing and standing problems are solved for high voltage lines maintenance personnel. During climbing, the electric power maintenance ladder is rapid, convenient, safe and reliable to assemble and is convenient to climb. After use of the ladder, the ladder is convenient to dismantle, package and transport. Thus, production cost and use cost are reduced.

Description

technical field [0001] The invention relates to an electric power maintenance ladder used for maintenance of transmission circuits. 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 fasten the connecting nuts. However, the high-voltage line is unstable and often cause...

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
