Description

An anti-detachment hook for an electric insulation protective umbrella

technical field

The utility model relates to a protective tool in the live operation of a transmission line, in particular to a detachment-preventing hook under an electric insulation protective umbrella.

Background technique

When working on high-voltage transmission lines, when working on a multi-layer cross-arm pole tower, hanging an insulating umbrella on the upper live wire can effectively protect the safety of the staff, but the hook door of the traditional insulating umbrella hook has no safety and is easy to unhook. , not only reduces the protection of high-voltage protection tools for operators, threatening personal safety, but also causes falling objects, threatening the personal safety of ground workers.

Contents of the invention

Aiming at the deficiencies of the above-mentioned technologies, the utility model provides an anti-detachment hook under the electric insulation protective umbrella, which prevents the wire from falling off from the hook mouth, solves the problem of accidental decoupling, and is easy to install and operate.

The utility model is realized by the following technical scheme: an anti-off hook for an electric insulation protective umbrella, including a hook body, a rotatable anti-off clamping plate is installed at the opening of the lower end of the hook body; Stay rope, a draw ring is installed on the stay rope.

The utility model has the advantages of:

1. Using the pull ring, the operation is safe, reliable, simple and easy, which ensures the safety of live work and prevents

Falling objects.

2. The tension spring is used as the force of the anti-off clamp, and the clamp ring acts as the working fulcrum of the operating rod, which is convenient

Disassembly, safe and reliable.

3. The positioning pin can effectively adjust the position of the clamping plate.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing is the structural representation of the utility model.

Among the figure: 1, clip ring, 2, connecting buckle, 3, stay rope, 4, positioning pin, 5, extension spring, 6, anti-off clip, 7, hook body, 8, wire.

Detailed ways

As shown in the accompanying drawings, a kind of power insulation protective umbrella anti-off hook has a hook body 7, and a rotatable anti-off clamping plate 6 is installed at the lower opening of the hook body 7; a pull cord is installed on the end of the anti-off clamping plate 6 3. A draw ring 1 is installed on the stay rope.

In order to facilitate the installation of the draw ring, a connecting buckle 2 is fixed on the draw ring 1, and the draw ring 1 is connected with the stay rope 3 through the connecting buckle 2. The tail end of the anti-off clamping plate 6 is fixed on the lower end of the opening of the hook body 7 by the positioning pin 4 and the extension spring 5. One end of the extension spring 5 is installed on the anti-off clamping plate 6, and the other end is installed on the hook body 7 at the lower end of the fixed pin. superior.

Working process: The operator uses the insulating operating rod to pick the pull ring 1 on the anti-detachment hook. At this time, the hook mouth is not blocked by the anti-detachment clamp 6. After hanging the insulating umbrella at a suitable position on the outer diameter of the wire 8, when the insulating rod is retracted , under the tension of the extension spring 5, the anti-off clamping plate 6 is put down, and the hook door is sealed to prevent the hook body 7 from decoupling with the wire 8. When dismantling hook, use insulating bar to pick draw ring 1 equally, as long as overcome extension spring 5 pulling force, by stay cord 3 traction, pull away anti-off clamping plate 6, anti-off clamping plate 6 can be taken back, release hook body 7.
