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

An electric power vertical maintenance ladder is disclosed. A connecting base is fixed on a fixed seat of the electric power vertical maintenance ladder. A connecting shaft connects the connecting base and a bearing seat. A gravity cone is installed on the bearing seat. After an inner conical hole and an outer conical surface match each other to be fixed well, an inner conical surface and the outer conical surface which fit well with each other are automatically locked through cooperation between a ring lock groove and a self-lock pin. A pedal is fixed on each ladder pillar. The electric power vertical maintenance 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 vertical 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 upright maintenance ladder 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 causes m...
