Portable insulator crawling ladder

Abstract

The invention discloses a portable insulator crawling ladder. The portable insulator crawling ladder is formed by at least three sections of ladder bodies (1) through connection, wherein every two sections of the adjacent ladder bodies are connected through a foldable connecting piece (2); clamping grooves (6) for mounting pedal plates (7) are uniformly formed in each section of the ladder body, and the pedal plates (7) and the clamping grooves (6) are connected through fixed bolts (4) to achieve folding; a Chinese character eight-shaped wire clamping groove (10) is formed in the bottom of the lowest section of the ladder body; a movable transverse rod (8) is connected to the upper part of the highest section of the ladder body through a rotating bolt (3); binding belts (9) for connecting a cross arm of a pole tower are connected to two ends of the movable transverse rod (8) and the top of the highest section of the ladder body. By virtue of the portable insulator crawling ladder, an operator can climb on or down the cross arm and leads without touching and damaging an insulator and has supporting points on hands and feet, so that the operation is safe, and the force is saved; furthermore, the portable insulator crawling ladder is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of tool manufacturing, in particular to a portable insulator ladder applied to hanging (composite) insulators. Background technique [0002] Various insulators appear on the transmission line year by year. During the maintenance process, climbing up and down is by using the insulator ladder, which is easy to damage the insulator itself, especially the synthetic insulator. The shed of the insulator is mostly made of suitable materials, such as Silica gel, etc., can easily damage the umbrella skirt; and there are no reserved positions for the upper and lower insulators on the tower, the upper and lower space restrictions, and the requirements for protecting the umbrella skirt from injury. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable insulator climbing ladder, through which the cross arm and the wire can be moved up and down, without t...

Problems solved by technology

[0002] Various insulators appear on the transmission line year by year. During the maintenance process, climbing up and down is by using the insulator ladder, which is easy to damage the insulator itself, especially the synthetic insulator. The shed of the insulator is mostly made of suitable materials, such as Silicone, etc., are very easy to damage the umbrella skirt; and there is no reserved position for the upper and lower insulators on the tower, the upper and lower space restrictions, and the requirements for protecting the umbrella skirt from injury. There are no favorable support points on the upper and lower insulator feet, which is very laborious and has a high safety risk
