Problems solved by technology

[0003] There is no special tool for pulling out and inserting the R pin in the prior art, and the pull out and insertion of the glass insulator R pin is completely construction. Manual work with pliers at close range requires construction personnel to work in the air, which is time-consuming and laborious, and the work safety is poor, and it is easy to damage the glass insulator again. When the line is live, the construction personnel pull out and insert the R pin at the same potential.

Abstract

The invention discloses a pulling and plugging device of an R pin needle of a glass isolator. The pulling and plugging device comprises an insulating rod (1), a pin puller head (2) or a bolt inserter head (3) connected and arranged on the end part of the insulating rod, or a pin puller head (2) and bolt inserter head (3) respectively arranged on two ends of the insulating rod (1). The pulling and plugging device has the advantages of convenience for manufacture, safety in using, convenience, time and labor saving, no need of suspension operation of constructors, and capability of hot-line work; and the personal can carry out earth potential working without being necessarily close to an electrified body, and stably pulls or plugs the R pin needle out or in.

Description

technical field [0001] The invention relates to an appliance for pulling out or inserting R pins on glass insulators of high-voltage transmission lines on iron towers and poles. Background technique [0002] Once the glass insulators of high-voltage transmission lines on iron towers and poles are damaged, they need to be repaired. To replace the damaged part, it is necessary to pull out the R pin needle on the glass insulator, remove the damaged part, and replace it. Insert the R pin needle. [0003] In the prior art, there is no special tool for pulling out and inserting the R-pin pins. To complete the pull-out and inserting work of the R-pin pins of the glass insulator, it is entirely manual work by the construction personnel with pliers at close range, which requires the construction personnel to work suspended in the air, which is time-consuming It is laborious, the work safety is poor, and it is easy to damage the glass insulator again. When the line is charged, the c...
