A combined detachable high-voltage line maintenance ladder

Abstract

The invention discloses a novel combined disassembling and assembling type high-voltage line maintenance ladder, and relates to the technical field of power supply stations. The ladder comprises a bottom plate, and the lower end of the bottom plate is evenly provided with four universal wheels at an equal distance in the circumferential direction of the bottom plate; the upper end of the bottom plate is provided with a main-level connector which is mutually welded to the upper end of the bottom plate through a first reinforcing rib plate; the main-level connector is connected with a matched head through fixing bolts which penetrate through the main-level connector and the matched head; the upper end of the matched head is mutually welded to a ladder column; three stepping plates are evenly welded to the side face of the ladder column at equal distance in the vertical direction; the middle of the upper end of the ladder column is provided with a locking hole; the upper end of the ladder column is welded to a secondary-level connector which is welded to the side face of the ladder column through a second reinforcing rib plate; a tapered cavity is formed in the secondary-level connector; the inner wall of the secondary-level connector is provided with a locking groove. The novel combined disassembling and assembling type high-voltage line maintenance ladder is simple in structure, convenient to operate, higher in matching strength and stability, capable of greatly improving the maintenance efficiency and worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of power supply stations, in particular to a combined disassembly type high-voltage line maintenance ladder. Background technique [0002] The power supply requires frequent maintenance and inspection of high-voltage lines, and high-voltage lines are generally placed higher than the ground, so it generally causes greater difficulties for workers to construct, and trees are often planted near high-voltage lines. , its branches are very close to the high-voltage line, sometimes even in contact with the high-voltage line, it is necessary to manually trim the branches of the tree to protect the high-voltage line. Since there is no tool for upright climbing to the height of branches at present, the usual practice of high-voltage line maintenance personnel is to cut off the branches of trees as a whole, which affects the growth of trees and also damages the green environment, which is not conducive to environmenta...

Problems solved by technology

Since there is no tool for upright climbing to the height of branches, the usual practice of high-voltage line maintenance personnel is to cut off the branches of trees as a whole, which affects the growth of trees and also damages the green environment, which 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, because the high-voltage line swings in the air and is unstable, often causing maintenance accidents
