Climbing tool for maintaining power transmission tower pole fork beam

Abstract

The invention discloses a climbing tool for maintaining a power transmission tower pole fork beam. The climbing tool comprises a left hoop and a right left hoop which are symmetrical, and a ladder, wherein an inside liner is arranged on the hoop inner ring of the right hoop, the inside liner is made from a flexible material, a through hole is formed in the lower part of a bolt fastening plate of the right hoop, and the left hoop and the right hoop are symmetrically installed on the power transmission tower pole fork beam through bolts and are in sliding fit with the power transmission tower pole fork beam frictionally; two hooks are arranged on the upper end of the ladder, and the two hooks are suspended in the through holes of the left hoop and the right hoop respectively. The left hoop and the right hoop are symmetrically installed on the power transmission tower pole fork beam, the hooks of the ladder are suspended in the through holes of the two hoops simultaneously, the two hoops naturally glide through the gravity of the ladder, the two hoops are clamped simultaneously through an oblique plane of the power transmission tower pole fork beam, and the ladder is steadily connected with the two hoops.The climbing tool is simple in structure and quick and convenient to assemble and disassemble, and guarantees that the ladder is non-slip, so that the labor efficiency can be improved, the labor intensity is alleviated, and the safety production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of inspection and maintenance of transmission towers, in particular to a climbing tool for inspecting and repairing the forks of transmission towers. Background technique [0002] In the power transmission line, the X-shaped fork beam connection of the cement pole is connected by four fork beam steel caps, each fork beam steel cap is fixed on the end of the cement pole, and the front and rear of the four fork beam steel caps Both sides are clamped with two square steel plates, and eight fastening bolts pass through the steel plates and the steel cap of the fork beam to fix together. Since the steel cap of the fork beam and the fastening bolts are located at high altitude, they are used in the atmosphere for a long time, and the weathering and corrosion are serious. Regular maintenance is required, and work such as painting anti-corrosion materials and fastening bolts must be carried out. In the prior art, t...

AI Technical Summary

Problems solved by technology

In the prior art, there is no special ladder or special platform for maintenance operators to directly lead to the joint of the X-shaped fork beam of the cement tower. During the maintenance operation, the operator needs to climb the X-shaped fork beam with bare hands. After reaching the maintenance position, there is no way to stand. It is very difficult to transport maintenance tools and anti-corrosion materials upwards only by connecting the safety belt to the X-shaped fork beam. The actual operation is very dangerous, which brings a lot of inconvenience to the maintenance work of the X-shaped fork beam on the cement pole.
