Safety net for electric transmission line constructing and tower erecting activities

Abstract

The invention relates to a safety net for electric transmission line tower erecting activities, iron tower materials are assembled outside the iron tower, main ropes are fixed between iron tower materials. The safety net is characterized in that three-jaw blunt end inner hooks are fixedly mounted on the main ropes at equal intervals, the blunt end of each three-jaw blunt end inner hook is an obtuse angle inner hook facing a middle shaft position, other main ropes are connected horizontally or vertically on three-jaw blunt end inner hooks between main ropes in a hanging ring manner so as to form a sealed activity safety net. According to the safety net provided by the invention, safety of a worker conducting horizontal work and vertical tower climbing is realized, when the worker conducts horizontal work, a safety rope is additionally arranged on the three-jaw blunt end inner hooks in conjunction with the safety hanging point of the steel rack; when the worker climbs the tower, in case of accidentally dropping, the three-jaw blunt end inner hook can hook the worker in the vertical direction, so as to avoid tower climbing dropping, at the same time, the three-jaw blunt end inner hook is capable of preventing the worker from being stabbed, resistance of the safety rope in the process of rising can be decreased, and the safety net can be untied to reuse after the operation is accomplished.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to the operation protection of transmission lines, in particular to a safety net for tower activities of transmission lines. Background technique [0002] In the erection of high-voltage power transmission line towers, in order to ensure the safety of the staff, the current application is to use safety ropes for protection. In the process of climbing and assembling the safety rope, due to the split state of the tower assembled by the angle iron, the climbing tower is faster and when working on the tower, the safety rope will have the problem of incoherent protection; although the self-locking device can be used for self-locking lock, but it leads to an increase in the weight of the climbing tower equipment, which is inconvenient to use. [0003] In addition, in the process of staff climbing and walking on the tower, a safety rope alone cannot guarantee the safety of the staff, and a lit...

AI Technical Summary

Problems solved by technology

In the process of climbing and assembling the safety rope, due to the split state of the tower assembled by the angle iron, the climbing tower is faster and when working on the tower, the safety rope will have the problem of incoherent protection; although the self-locking device can be used for self-locking lock, but it leads to an increase in the weight of the climbing tower equipment, which is inconvenient to use

[0003] In addition, in the process of staff climbing and walking on the tower, relying on a safety rope alone cannot guarantee the safety of the staff, and a little carelessness can easily cause casualties

Therefore, the existing safety rope mode cannot realize the safe operation of the staff
