Tandem type upright ladder for maintaining high-voltage lines

Abstract

The invention discloses a tandem type upright ladder for maintaining high-voltage lines. The ladder is characterized in that a chassis of the ladder is fixed by being matched with an outer conical surface at the lower end of a ladder post body via a middle inner cone hole; the outer conical surface of the ladder post body is fixed by being matched with an inner conical surface of the inner cone hole of the ladder post body; after the inner cone hole is fixed by being matched with the outer conical surface, the inner conical surface and the outer conical surface, which are jointed, are automatically locked by matching a locked groove in the outer conical surface with a shotpin; pedals are fixed on the surface of a post body of the ladder post body; anti-slip glue adheres to the pedals and the bottom of the chassis. The tandem type upright ladder for maintaining high-voltage lines has the beneficial effects that the ladder has a simple structure and is quite convenient to manufacture, assemble and use; tools are not needed in the assembling and dismantling processes during use of the ladder; after the tandem type upright ladder for maintaining high-voltage lines is adopted, the problem that high-voltage line maintenance men climb and stand uprightly is solved; the ladder for maintaining high-voltage lines is fast, convenient, safe and reliable to assemble during climbing and is convenient to climb; after being used, the ladder is convenient to dismantle, package and transport, thus reducing the production cost and the use cost.

Description

Technical field [0001] The invention relates to a series-connected upright high-voltage line maintenance ladder used for upright climbing when the high-voltage line maintenance personnel repair the high-voltage line. Background technique [0002] Trees are planted near high-voltage transmission lines. 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; The height of the branches is a tool for high-voltage line maintenance personnel to cut down the entire tree, which damages the green environment and is not conducive to environmental protection. In the maintenance of high-voltage lines, the maintenance personnel first climbed up the utility poles and then the high-voltage lines, standing or lying on the high-voltage lines to check and tighten the connecting nuts. However, the high-voltage lines are unstable and...

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
