Abstract

The invention relates to a movable safety net for towers of transmission lines. Iron tower materials are assembled on the outside of the iron towers, and main ropes are fixed between the iron tower materials. The blunt inner hook, the hook head of the three-claw blunt inner hook is an obtuse angle inner hook facing the central axis, and the three-claw blunt inner hook between the main ropes is connected to other hooks in the vertical or horizontal direction by means of a hanging ring. The main rope thus forms a closed movable safety net. This safety net can realize the safety of the staff when they work horizontally and vertically climb the tower. When climbing the tower, when the staff falls down by accident, the three-claw blunt inner hook will hook the staff in the vertical direction to prevent the tower from falling. At the same time, the three-claw blunt inner hook can prevent the staff from being stabbed. Resistance can also be reduced during the ascent process, and the safety net can be quickly removed and reused after completing the operation.

Description

Transmission line erection tower activity safety net

technical field

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

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.

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 little carelessness can easily cause casualties. Therefore, the existing safety rope mode cannot realize the safe operation of the staff.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a safety net with scientific structure design, convenient use, safety and reliability for the tower activity of transmission lines.

The technical scheme that the present invention solves technical problem adopts is:

A movable safety net for towers of transmission lines, in which iron tower materials are assembled on the outer side of the iron towers, main ropes are fixed between the iron tower materials, and the feature is that the main ropes are evenly spaced and fixed with three-claw blunt inner Hook, the hook head of the three-claw blunt inner hook is an obtuse angle inner hook towards the central axis, and the three-claw blunt inner hook between the main ropes is connected to other main ropes in the vertical or horizontal direction by means of a ring. This forms a closed activity safety net.

Moreover, the fixing method of the three-claw blunt inner hook and the main rope is to adopt a knot on the main rope, that is, knots are formed on the upper and lower main ropes of the three-claw blunt inner hook, The three-claw blunt inner hook is positioned on the main rope between the knots, or the direct fixing method of the fixing sleeve and the main rope is adopted.

Advantage and positive effect of the present invention are:

1. The safety net is equipped with three-claw blunt inner hooks evenly distributed on the main rope between the steel frames, and the safety rope is installed on the adjacent main rope, thus forming a safety net between the steel frames. The layout effectively guarantees the personal safety of the staff.

2. This safety net can realize the safety of the staff when working horizontally and climbing the tower vertically. When working horizontally, a safety rope can be added to the inner hook of the three-claw blunt head, and it can be used together with the safety hanging point of the steel frame; When climbing the tower, when the tower climber falls, the three-claw blunt inner hook will hook the staff in the vertical direction to prevent the tower from falling. At the same time, the three-claw blunt inner hook can prevent the staff from being stabbed. Resistance can also be reduced during the ascent of the safety rope, and the safety net can be untied quickly and reused after completing the operation.

3. The three-claw inner hook used in this safety net can be conveniently and quickly attached to the safety rope, and has a simple structure and a scientific design. The inner hooks of the three-claw blunt head of the protection rope are evenly spaced on the main rope to avoid the "blind spot" problem of the climbing tower without safety rope protection, and improve the safety performance of the tower climbers.

Detailed ways:

In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings. It should be noted that this embodiment is descriptive, not restrictive, and cannot thereby limit the protection scope of the present invention.

A movable safety net for a power transmission line tower, in which iron tower materials 4 are assembled on the outside of an iron tower 1, main ropes 3 are fixed between the iron tower materials, and the iron towers are equipped with cable-stayed wires 2, thereby maintaining the upright state of the iron towers.

The innovation of the present invention is:

1. Three-claw blunt-head inner hooks 5 are evenly distributed on the main rope. The hook head of the three-claw blunt-head inner hook is an obtuse angle inner hook toward the central axis, so that the safety rope entering the hook head cannot take off. The fixing method of the inner hook of the three-claw blunt head and the main rope is to adopt the method of forming a knot 6 on the main rope, that is, there are knots on the main rope at the upper and lower ends of the inner hook of the three-claw blunt head, so that the three-claw blunt head The blunt inner hook is positioned on the main rope between the knots; it is also possible to use the direct fixing method of the fixing sleeve and the main rope.

2. The three-claw blunt inner hook between the main ropes can also be connected to the main rope (safety rope) by means of a hanging ring, which can be mounted vertically or horizontally, thereby forming a closed movable safety net.

3. The inner hook with three-claw blunt head can be made of carbon fiber to ensure strength.

Claims (2)

1. A kind of activity safety net of transmission line group tower, in the outer side of iron tower, iron tower tower material is set up, main rope is fixed between the iron tower tower materials, it is characterized in that: on the main rope, evenly distributed interval is fixedly equipped with three claws blunt The head inner hook, the hook head of the three-claw blunt-head inner hook is an obtuse-angle inner hook facing the central axis, and the three-claw blunt-head inner hook between the main ropes is connected to other main ropes in the vertical or horizontal direction by means of a hanging ring. The rope thus forms a closed movable safety net. 2. The movable safety net for towers of transmission lines according to claim 1, characterized in that: the fixing method of the three-claw blunt inner hook and the main rope is: the main rope at the upper and lower ends of the three-claw blunt inner hook There are knots on the top, so that the inner hook of the three-claw blunt head is positioned on the main rope between the knots.
