Climbing anti-falling device applied to power transmission line engineering

Abstract

The invention discloses a climbing anti-falling device applied to power transmission line engineering. The climbing anti-falling device comprises a steel strand, and the steel strand is laid on a main rod or a crawling ladder of a tower and is fixedly connected with the tower through a plurality of anti-swing rings and a double-hook wire fixing device; the anti-swing rings are vertically distributed on the tower and are fixedly connected with the tower; the double-hook wire fixing device is horizontally distributed on a tower and is fixedly connected with the tower; the signboard is arranged on the steel strand and is fixedly connected with the tower; the self-locking type falling protector is arranged on the steel strand in a sliding mode and connected with a worker through a connector and a connecting rope, and a monitor is arranged on the self-locking type falling protector. Compared with the prior art, the self-locking type falling protector has the following advantage that potential safety hazards caused by repeated installation of the self-locking type falling protector are eliminated. And the steel strand is prevented from swinging excessively in the climbing process of a worker. The steel strand in the climbing anti-falling device is processed by adopting a new process and a new material, so that the strength, the toughness and the fatigue strength of the steel strand are improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a climbing and falling prevention device applied to power transmission line engineering. Background technique [0002] When carrying out power transmission line projects, staff are required to climb towers. In order to ensure the safety of staff, it is usually necessary to use climbing anti-fall devices to protect the climbing staff from falling. However, the existing climbing anti-fall device only fixes a plurality of curved fixing rods on the surface of the tower, and then connects the hooks of the safety belts used by the staff with them. [0003] The Chinese patent with publication number CN110639139A discloses a high-voltage transmission line tower anti-fall device and method with differential self-locking device, the device includes: an iron tower; The tower body; an anti-fall device is provided on the iron tower, and the anti-fall device includes: a diffe...

AI Technical Summary

Problems solved by technology

[0004] However, the anti-fall device in the above-mentioned technical solution also has the following deficiencies: 1. The differential self-locking of the anti-fall device needs to fix the fixed end on the The top of the climbing frame or the top of the tower body is cumbersome to operate and is not conducive to fast operation; 2. The staff needs to frequently move on the pole tower when climbing through the climbing frame, and then in the process of moving, the staff needs to go back and forth The hook is removed and installed, but the seat belt is removed back and forth, which greatly reduces the safety of the staff, and there are great potential safety hazards, and the safety guarantee is not high enough.
