Description

High and low voltage grounding wire hook with adjustable direction

technical field

The utility model belongs to the technical field of temporary grounding wire devices, in particular to a hook that can be used for indoor and outdoor lines, equipment maintenance, and grounding wires.

Background technique

At present, most of the grounding wire hooks used for power transmission and distribution lines and equipment are composed of an insulating operating rod, a spring-loaded hook clip and a grounding wire. Very inconvenient. For the maintenance and repair of outdoor power transmission lines, the grounding wire hook with the opening of the wire clip facing downwards is used, and it only needs to be hung and pulled on the wire. For the maintenance and repair of equipment wire clips and aluminum bars in the horizontal direction, use the ground wire hook with the opening of the wire clip facing left or right, and just touch the wire clip or aluminum bar. For the maintenance and repair of the distribution box or transformer, use the grounding wire hook with the opening of the wire clamp upward, and just push it to the connecting row or the high and low voltage pillars. Due to the different line environments, power supply maintenance and repair departments must be equipped with ground wire hooks facing different directions, and they must also carry the ground wire hooks facing different directions during work, which makes storage and carrying very inconvenient and poses a safety hazard.

Contents of the invention

The purpose of this utility model is to provide a high-voltage and low-voltage grounding wire hook with adjustable direction which is very convenient for storage and carrying and has high safety.

The technical solution of the utility model is: a high-voltage and low-voltage grounding wire hook with adjustable direction, including an insulating operating rod, a spring-pressed hook clamp and a grounding wire, and is characterized in that it also includes a U-shaped clamp to fix the frame; the spring-loaded hook clamp is fixed on the U-shaped clamp fixed conductive frame through the clamp fixing screw; the grounding wire is fixed on the U-shaped clamp fixed conductive frame; the U-shaped clamp fixed conductive frame is connected with the insulating operation rod .

The U-shaped wire clip fixing conductive frame described in the technical solution of the utility model is connected with the insulating operation rod through the matched butt joint and the butt joint seat.

The utility model adopts a grounding wire hook composed of an insulating operating rod, a U-shaped wire clip to fix the conductive frame, a spring-pressed hook clip and a grounding wire, wherein the spring-pressed hook clip is fixed on the The U-shaped wire clamp is fixed on the conductive frame, the grounding wire is fixed on the U-shaped wire clamp fixed conductive frame, and the U-shaped wire clamp fixed conductive frame is connected with the insulating operation rod. Therefore, according to the needs of maintenance and repair sites, the wire can be loosened first. Clamp the fixing screw, adjust the orientation of the clamp opening, and then tighten the clamp fixing screw to meet the needs of power transmission and distribution lines, equipment maintenance, and inspection and grounding. Because the utility model adopts the matching butt joint and the butt joint seat to connect between the U-shaped clamp fixed conductive frame and the insulating operation rod, it can meet the needs of 380V to 220KV voltage insulation by replacing the insulating operation handles of different lengths. Compared with the prior art, the utility model has the characteristics of one pole with multiple functions, very convenient storage and carrying, and high safety. The utility model is mainly used for high and low voltage ground wire hooks with adjustable direction of grounding during indoor and outdoor lines, equipment maintenance and overhaul.

Detailed ways

As shown in Figure 1. The utility model is composed of an insulating operating rod 6, a U-shaped wire clip fixing a conductive frame 3, a spring-loaded hook wire clip 1 and a grounding wire 7. Wherein, the insulation operating rod 6, the spring-loaded hook clamp 1 and the ground wire 7 are the same as those of the existing ground wire hook, and the difference is that a U-shaped wire clamp is added to fix the conductive frame 3. The spring-loaded hook clamp 1 is fixed on the U-shaped clamp fixing conductive frame 3 through the clamp fixing screw 2. According to the needs of the maintenance and overhaul site, first loosen the clamp fixing screw and adjust the orientation of the opening of the clamp , and then tighten the wire clip fixing screw to meet the needs of power transmission lines, equipment maintenance, and inspection grounding. The grounding wire 7 is fixed on the U-shaped wire clamp fixed conductive frame 3. The grounding wire 7 is made of multiple strands of high-quality annealed copper wires, and is covered with a soft, high-temperature-resistant transparent insulating sheath, which can prevent the grounding copper from being damaged during use. The wear and tear of the line ensures the safety of the workers in operation. The U-shaped wire clip fixed conductive frame 3 is connected with the insulating operation rod 6 through the matching butt joint 4 and the docking seat 5, and the insulation operation handle of different lengths can be replaced to meet the needs of 380V to 220KV voltage insulation. The insulating operating rod 6 is made of high-grade epoxy resin and glass fiber with excellent insulating performance and mechanical strength. At the same time, a silicone rubber sheath is added to the operating handle to make the insulation safer and more reliable. The spring-loaded hook clamp 1 and the U-shaped clamp fixed conductive frame 3 are made of high-quality aluminum alloy pressure casting, and the metal of the fasteners matched with it are all nickel-plated, so they are durable.
