Description

GW4-110 type isolating switch maintenance special wrench

Technical field:

The utility model relates to a wrench, in particular to a GW4-110 type isolating switch maintenance special wrench, which belongs to the technical field of electrical equipment.

Background technique:

GW4-110 type isolating switch is widely used in the power industry, especially in substations. In order to make it operate safely, it must be overhauled every 4-5 years. The vertical connecting rod bearing cover plate on it is a disc. Due to the long-term contact of the vertical connecting rod bearing cover with air, rainwater will seep into the interior, causing the contact surface of the cover to oxidize and become rusted. It is difficult for maintenance personnel to remove the cover during disassembly and assembly.

Utility model content:

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, and provide a GW4-110 type isolating switch maintenance special wrench with simple structure, convenient use, time-saving and labor-saving.

The technical scheme that the utility model takes for solving the technical problem is:

A GW4-110 type isolating switch maintenance special wrench, including a grip handle, the top of the grip handle is fixed with a U-shaped bracket, and the two sides of the top of the U-shaped bracket are respectively equipped with grabbing heads, and the lower end of the grip handle is It is provided with a grip groove.

The distance between the two gripping heads provided on both sides of the top of the U-shaped bracket is equal to the distance between the two symmetrical holes on the isolating switch cover plate.

The positive and beneficial effects of the utility model are as follows:

The utility model is provided with two grasping heads on both sides of the top of the U-shaped bracket, and the distance between the two grasping heads is equal to the distance between the two symmetrical holes on the isolating switch cover plate. The two grasping heads of the wrench are inserted into the symmetrical small round holes of the cover plate, and the cover plate can be removed by twisting the grip handle, which is simple and convenient to operate and high in efficiency.

The utility model is provided with concave grooves on both sides of the handle, which can enhance the bearing and force-bearing effect of the GW4-110 type isolating switch maintenance special wrench, thereby reducing the work burden of the staff.

The utility model has the advantages of simple structure, novel design and convenient use, which not only solves the problem that the maintenance personnel are not easy to remove the cover plate during disassembly, but also improves the work efficiency of the maintenance personnel.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the right side view of Fig. 1 .

Detailed ways:

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

Referring to Fig. 1 and Fig. 2, a GW4-110 type isolating switch maintenance special wrench includes a grip handle 1, a U-shaped bracket 2 is fixed on the top of the grip handle 1, and the two sides of the top of the U-shaped bracket 2 are respectively equipped with The gripping head 3 is provided with a gripping groove 4 at the lower end of the gripping handle 1, wherein the distance between the two gripping heads 3 provided on both sides of the top of the U-shaped bracket 2 is the same as the distance between the two symmetrical holes on the isolating switch cover plate. The distance between them is equal.

In the utility model, the distance between the two grasping heads 3 is equal to the distance between the two symmetrical holes on the isolating switch cover plate, so that the maintenance personnel only need to insert the two grasping heads 3 of the wrench into the symmetrical holes on the cover plate when using it. In the small round hole, the cover plate can be removed by twisting the handle 1. The structure is simple and easy to use. It not only solves the problem that the maintenance personnel are not easy to remove the cover plate during disassembly, but also improves the work efficiency of the maintenance personnel. , and easy to promote.
