In this way, not only the cost is high, but also the effect of reducing jamming is not very good. One is to adopt an S-shaped design, and the side guards and cams are in contact with the guide rails, which can reduce jamming, but due to the moving parts, the cost is high. , short life, inconvenient to use, low efficiency

Abstract

The invention relates to the field of electric power engineering equipment, in particular to a falling prevention device. The falling prevention device comprises at least one finger-like bent portion and a rod-like portion. The rod-like portion comprises an arc portion, and the arc portion comprises a through hole. When the falling prevention device is in a sliding state, the contact area between the falling prevention device and a track is small, blocking is not formed, and sliding is convenient; when a person falls, the finger-like bent portion makes contact with the track, the rod-like portion clamps the track under the lever effect, and falling is prevented; and the service life is prolonged, safety is improved, and the purposes that efficiency is improved and the cost is reduced are achieved.

Description

technical field [0001] The invention relates to the field of electric power engineering equipment, in particular to a fall prevention device. Background technique [0002] In electric power operations, overhead lines and maintenance of overhead lines are required, which requires personnel to climb the iron tower, and safety protection facilities, such as fall prevention devices, are required. [0003] Usually, the anti-fall device is designed in a square shape and adopts the design of covering the guide rail. The contact area with the guide rail is relatively large, and it is easy to form jams when sliding. Therefore, methods to reduce jamming are adopted, such as installing Insert steel balls to reduce the contact area, or install copper rollers to reduce the contact area. In this way, not only the cost is high, but also the effect of reducing jamming is not very good. One is to adopt an S-shaped design, and the side guards and cams are in contact with the guide rails, whi...
