Easy to use, good reliability, wide application range and can be used for 110--220 kV transmission lines.

Description

A kind of insulator R type pin movable special pin puller

technical field

The utility model relates to the field of electric power maintenance tools, in particular to a special pin puller for movable R-type pins of insulators. the

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. the

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 longer R-type pins, seriously affecting work efficiency. the

Utility model content

The technical problem to be solved by the utility model is to provide a special pin puller for the movable R-type pin of the insulator. The utility model can adjust the position of the pin-taking head according to the length of the R-type pin. Pulling out the R-type pin saves working time. the

The technical scheme that the utility model adopts is:

An insulator R-type pin movable special pin puller, including a handle, a support rod, a support block and a pin removal head; one end of the support rod is connected with the handle, and the other end is connected with the support block, and the support rod is close to the support block The position is provided with a chute, the pin-removing head is slidably arranged in the chute, the pin-removing head is perpendicular to the direction of the handle, and the support rod is provided with a positioning hole on one side of the chute for fixing the pin-removing head, and the positioning hole With internal thread and perpendicular to the direction of the pin removal head.

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

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

The tool for pulling out R-shaped pins pioneered by this utility model can adjust the position of the pin head according to the length 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; It is novel in design, easy to use, good in reliability, wide in application range and can be used in 110--220 kV transmission lines. the

Detailed ways

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

A kind of insulator R-type pin movable special pin puller, as shown in Figure 1 and 2, it includes a handle 1, a support rod 2, a support block 3 and a pin removal head 4; one end of the support rod is connected with the handle, and the other end is connected with the support The blocks are connected, and the support bar is provided with a chute 5 near the position of the support block, the pin removal head is slidably arranged in the chute, and is perpendicular to the direction of the handle, and a barb 8 is provided on the crotch of the pin removal head. The front end of the support block is provided with an anti-slip pad 7, and the support rod is provided with a positioning hole 9 on one side of the chute for fixing the pin removal head, and the positioning hole has internal threads and is perpendicular to the direction of the pin removal head. the

When in use, adjust the position of the pin removal head according to the length of the R-shaped pin so that the support block can have a stable support point, and then use the screw 6 to fix the pin removal head through the threaded connection of the positioning hole, hold the handle, and pull the hook of the pin removal head Penetrate 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. the
