Protection device used for electric transmission line tower climbing operation

Abstract

The invention relates to a protection device used for electric transmission line tower climbing operation, is particularly suitable for being used in overhead transmission line construction, interruption maintenance, operation with power uninterrupted and other tower climbing operation and belongs to the technical field of electric transmission line pole and tower field operation tools. The protection device comprises a safety rope with one end being hung on the human body, a plurality of short tying ropes which are arranged at intervals in the height direction of an electric transmission line pole and tower, and a differential speed blocking device which is used for clamping the safety rope which rapidly rotates anticlockwise. The differential speed blocking device is provided with a wire inlet which is used for penetrating the safety rope, a wire outlet and a clamping mechanism. The protection device is simple in structure, convenient to use, safe, reliable, wide in application range and high in operation efficiency.

Description

technical field [0001] The invention relates to a protection device for power transmission line tower climbing operations, which is particularly suitable for use in tower climbing work such as overhead power transmission line construction, power outage maintenance, and non-power outage operations, and belongs to the technical field of power transmission line pole tower on-site operation tools. Background technique [0002] The transmission line tower is used to support the wire and the lightning arrester, and to ensure the distance between the wire and the wire, between the wire and the lightning arrester, between the wire and the tower, as well as between the wire and the ground, buildings, power lines, communication lines, etc. A certain safe distance. Tower climbing operations are required in tower erection, line setting out, power outage maintenance, live detection, etc. Usually, the height of transmission line towers is above 20m, and tower climbing operations are high-...

AI Technical Summary

Problems solved by technology

Tower climbing operations are required in tower erection, line setting out, power outage maintenance, live detection, etc. Usually, the height of transmission line towers is above 20m, and tower climbing operations are high-altitude operations. During the process of climbing towers, staff may slip , slipping, collision and other hazards, which may lead to personal injury and death accidents such as high school falling

[0003] The existing protection devices such as safety belts and backup protection ropes can only be used after the staff climb to the appropriate position, and can only provide protection for the staff during the working process or displacement process on the tower, and cannot provide protection for the staff during the boarding process. Provides effective protection during the tower process

The common track-type fall arrester is only suitable for a very small number of towers with tracks. Most of these towers are used in training venues, and most of the towers in the actual working environment do not have tracks. Therefore, the existing fall arresters Protector protection cannot be used at the job site

[0004] At present, there is no device in the world that can provide reliable safety protection for workers climbing towers. Therefore, it is urgent to develop a new type of protection device to ensure the safety of power transmission line workers during tower climbing operations.
