Fall-proof device for electric power test climbing and application method thereof

Abstract

The invention discloses a fall-proof device for electric power test climbing and an application method thereof. The fall-proof device comprises a box body, wherein the top side of the box body is provided with a groove; two positioning plates are welded in the groove; screw rods are welded at the tops of the positioning plates; the outer sides of two screw rods are movably sleeved with one same cover plate; onesame limiting rod iswelded between the bottom of one of the two positioning plates and the bottom inner wall of the groove; the outer side of the limiting rod is movably sleeved with a sliding plate; two brackets are welded at the bottom of the sliding plate; the bottoms of the brackets are rotatably provided with rotating shafts; onesame winding wheel is welded at theends, close toeach other, of the rotating shafts; and one end of a traction rope is wound and fixedly arranged on the winding wheel. The fall-proof device for electric power test climbing and the application methodthereof have reasonable design, can increase elastic force of a first spring, a second spring and a third spring, conveniently adjust the length of the traction rope, can buffer a hook and the traction rope, avoid the hookbreakage caused by the excessive instantaneous force, and are conducive to use.

Description

technical field [0001] The invention relates to the technical field of anti-fall equipment, in particular to an anti-fall equipment used for power test climbing and a method for using the same. Background technique [0002] In the maintenance of high-altitude power equipment, in order to improve safety, a fall arrester is usually used and connected to the staff to prevent the maintenance personnel from falling. For example, the application number is [0003] The patent document of 201611127367.5 discloses an anti-falling device for electric power test climbing, including an upper support plate and a lower support plate, a hanging ring is arranged at the lower end of the lower support plate, and at least two connecting rods are arranged on the lower supporting plate, and the upper ends of the connecting rods penetrate The upper support plate is fixed by nuts, and an arc-shaped strip hole is arranged on the lower support plate. The lower end of the connecting rod passes throu...

AI Technical Summary

Problems solved by technology

[0004] Because when the staff falls, the anti-fall device will be subjected to instantaneous force. The existing anti-fall device is directly hung on the power pole or cable. When the staff suddenly falls, it is prone to decoupling or due to the instantaneous force And breakage will cause casualties, which is not conducive to use, so we propose a fall prevention device for electric power test climbing to solve the above problems
