Description

A kind of insulator R type pin replaceable special pin puller

technical field

The utility model relates to the field of electric power maintenance tools, in particular to a special pin-pulling pliers for replaceable R-shaped pins of insulators.

Background technique

At present, new type R pins are commonly used in the cross-arm side bowls of composite insulators for high-voltage transmission lines. However, during the operation of transmission lines, insulators are often damaged due to external force damage or other reasons. Unqualified insulators must be replaced in time. , To replace the insulator, it is necessary to pull out the R-shaped pin in the bowl head of the insulator cross arm, but this R-shaped pin has the advantages of not easy to deform and stable performance, so it is not easy to take out after installation.

Due to different application occasions, the R-type pins also have different sizes during use. We generally use hand pliers or common pliers to pull out the R-type pins when replacing insulators. This method is very troublesome, time-consuming and laborious. And it is more difficult to pull out some larger or smaller R-type pins, seriously affecting work efficiency.

Utility model content

The technical problem to be solved by this utility model is to provide a kind of insulator R-type pin replaceable special pin puller. The utility model can replace different pin-removing heads according to the size of the R-type pin. It is easy to use and utilizes the principle of mechanics. The R-shaped pin can be pulled out quickly, saving working time.

The technical scheme that the utility model adopts is:

A special pin-removing pliers for R-type pins of insulators, including a pin-removing rod and a pin-removing head. The pin-removing rod includes a handle, a support rod and a support block. There is a connection hole with internal thread on the support rod, the connection hole is close to the support block and perpendicular to the direction of the handle, the pin removal head is composed of a hook and a screw rod, and is connected to the support rod through the screw rod and the connection hole .

The crotch hooks on the pin-removing head have different sizes, and different pin-removing heads can be replaced according to the size of different R-type pins.

An anti-skid pad is provided on the support block to prevent the support block from slipping when positioning the support.

The crotch of the pin-removing head is provided with barbs, which can effectively prevent the pin-removing head from slipping when the R-shaped pin is pulled out.

The tool for pulling out R-shaped pins pioneered by the utility model can replace different pin-removing heads according to the size of the R-shaped pins, so that the pulling out of the R-shaped pins is more time-saving and labor-saving, and the work efficiency is improved; the principle of mechanics is cleverly used , Novel design, easy to use, good reliability, wide application range can be used for 110--220 kV transmission lines.

Detailed ways

The technical solution of the present invention will be further specifically described below in conjunction with the accompanying drawings.

A kind of insulator R type pin replaceable special pin puller, as shown in Figure 1, includes a pin removal rod and a pin removal head, and the pin removal rod includes a handle, a support rod and a support block, wherein one end of the support rod is connected with the handle, and the other end is connected with the The support blocks are connected, and a connecting hole 4 with an internal thread is provided on the support rod. The connecting hole is close to the support block and is perpendicular to the direction of the handle. Constitute with screw rod 6, be provided with barb 8 on its crotch, get pin head and be connected on the support rod by screw rod and connecting hole.

In practical application, because the size of the insulator is different, the size of the R-type pin used for fixing is also different. The type and size of the R-type pin are also specified in the machinery industry standard. The utility model is based on different R-type pins. The pin is designed with hooks of different sizes. When using it, select the appropriate pin removal head according to the size of the R-shaped pin, and connect it to the support rod through the screw rod and the connecting hole. Hold the handle, insert the hook of the pin-removing head into the pin hole of the R-type pin, and use the support block to locate the support point, then the R-type pin can be pulled out quickly by using the lever principle of mechanics.
