Upright serially-connected high-voltage line maintaining ladder

Abstract

The invention discloses an upright serially-connected high-voltage line maintaining ladder. A stabilizing seat of the upright serially-connected high-voltage line maintaining ladder is fixed through being matched with an outer conical surface located at the lower end of an upright column body through a middle inner conical hole, and the outer conical surface of the upright column body is fixed through being matched with the inner conical surface of the inner conical hole of the upright column body; the inner conical surface and the outer conical surface which are fitted are automatically locked through the matching of a braking slot in a locking rod and a brake pin after the inner conical hole is fixed through being matched with the outer conical surface; and the surface of the upright column body is fixedly provided with steps on which antiskid rubber is adhered, and antiskid rubber is also adhered to the bottom of the stabilizing seat. The upright serially-connected high-voltage line maintaining ladder is simple in structure and very convenient to manufacture, assemble and use, and no tools are needed in the assembling and disassembling processes when the ladder is used; after the upright serially-connected high-voltage line maintaining ladder is adopted, the problems on the aspects of uprightly climbing and standing of high-voltage line maintaining personnel are solved, and the high-voltage line maintaining ladder is rapid, convenient, safe and reliable to assemble and convenient to climb when being used for climbing; and after being used, the upright serially-connected high-voltage line maintaining ladder is convenient to disassemble, package and transport, so that the production and use costs are reduced.

Description

technical field [0001] The invention relates to an upright series-connected high-voltage line maintenance 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...

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
