Abstract

The utility model discloses a tool for pulling out R pins, which is used for pulling out R pins on insulators in power grid outdoor operations. It includes a handle, a connecting rod, and a pin hook for hooking R pins. At one end of the connecting rod, the front part of the pin hook is bent toward the connecting rod to form a hook; the other end of the connecting rod is connected with the handle and the axes of the two intersect; the length of the connecting rod is less than the radius of the applicable porcelain bottle. It can easily and quickly pull out the R pin of the insulator to improve the maintenance efficiency, is convenient to use, saves time and labor, has a simple structure, is easy to manufacture, and has low cost.

Description

R pin removal tool

technical field

The utility model relates to a tool for power grid workers to work outdoors, in particular to a tool for pulling out the R pin of an insulator.

Background technique

Because power grid workers are working outdoors, when replacing and installing insulators, it is difficult to remove the R pin, so the efficiency of insulator replacement and installation is often reduced.

Utility model content

In order to overcome the disadvantages of the above-mentioned prior art, the purpose of this utility model is to provide a R-pin removal tool, which can quickly remove the R-pin from the insulator, and is easy to operate, labor-saving, and high in efficiency.

In order to solve the above problems, the utility model adopts the following technical solutions: the R pin removal tool includes a handle, a connecting rod, a pin hook for hooking the R pin, the rear part of the pin hook is fixedly connected to one end of the connecting rod, The front part of the pin hook is bent toward the connecting rod to form a hook; the other end of the connecting rod is connected with the handle and the axes of the two intersect; the length of the connecting rod is less than the radius of the applicable porcelain bottle.

As a further technical solution of the utility model:

In the R pin extraction tool, the pin hook is tapered, and the diameter of the front end of the pin hook is smaller than the diameter of the rear end.

The beneficial effects of the utility model are: it can easily and quickly pull out the R pin of the insulator so as to improve the maintenance efficiency, is convenient to use, saves time and effort, has a simple structure, is easy to manufacture, and has low cost.

Description of drawings

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

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

Fig. 2 is the A-A view of Fig. 1,

Fig. 3 is the B-B view of Fig. 1,

In the figure: 1 handle, 2 pin hooks, 3 connecting rods.

Detailed ways

As shown in FIG. 1 , the R pin extraction tool includes a handle 1 , a connecting rod 3 , and a pin hook 2 for hooking the R pin. Wherein the pin hook 2 is conical, as shown in Figure 3, the diameter of the front end of the pin hook 2 is smaller than the diameter of the rear end. The rear portion of the pin hook 2 is affixed to one end of the connecting rod 3, and the front portion of the pin hook 1 is bent into a hook towards the connecting rod 3 direction. The other end of the connecting rod 2 is connected with the handle 1 and the axes of the two intersect; the length of the connecting rod 3 is less than the radius of the applicable porcelain bottle.

During manufacture, the handle and the connecting rod are integrated and are cylindrical, as shown in Figure 2; the pin hook can be welded on the connecting rod.

When the staff pulls out the R pin of the insulator, the pin hook 2 of the tool can be inserted into the O-ring of the R pin, and the staff only needs to tilt the handle 2 to drive the pin hook to pull out the R pin easily and quickly, and the operation is simple , save time and effort, improve maintenance efficiency, suitable for grid personnel working outdoors. According to the principle of leverage, the longer the handle 1 is, the more labor-saving the operation will be.

The utility model is not limited to the above-mentioned embodiments.

Claims (2)

1, a kind of R pin extraction tool, it is characterized in that: comprise handle, connecting rod, be used to hook the pin hook of R pin, the rear part of described pin hook is fixedly connected to one end of connecting rod, the front part of pin hook faces The direction of the connecting rod is bent into a hook; the other end of the connecting rod is connected with the handle and the axes of the two intersect; the length of the connecting rod is less than the radius of the applicable porcelain bottle. 2. The R pin removal tool according to claim 1, wherein the pin hook is tapered, and the diameter of the front end of the pin hook is smaller than the diameter of the rear end.
