Problems solved by technology

[0002] When the pin insulator is installed, the bottom of the screw will be screwed to the fixing nut. Since the insulator is installed at a high position, it will be in the wind blowing state for a long time. During the process of the wind direction changing back and forth, the fixing nut will gradually loosen, which will cause the pin insulator to fall off. drop, affecting line operation
Regarding fastening the fixing nut in the prior art, a sleeve that can twist the fixing nut is installed on the top of the insulating rod, but due to the limited length of the insulating rod, it often happens that the distance between the operating position of the operator and the insulator is slightly It is longer than the length of the insulating rod. If the insulating rod is used for butt joint, the length is too long, which is very inconvenient during the fastening process.
As the length of the insulating rod increases excessively, the alignment between the sleeve and the nut becomes more and more difficult, often causing the set nut to completely disengage from the threaded rod

Embodiment

[0010] Example: such as figure 1 As shown, the live fastening 10 kV pin insulator special tool includes an insulating rod 7, the upper part of the insulating rod is provided with an external thread, and a plug 5 is provided, and the lower end of the connector 6 is open and provided with an internal thread, which is screwed with the upper end of the insulating rod 7. A plug 5 is also arranged at the upper end of the connector 6 . A slot 4 is arranged on the lower end surface of the sleeve 2, a hexagonal screw hole is arranged on the upper end surface, and a nut cover 1 is arranged on the hexagonal screw hole outer cover.

[0011] The nut cover 1 is a hexagonal prism with an open upper end, the upper port of the hexagonal prism is larger than the lower port, and the size of the lower port is the same as the aforementioned hexagonal screw hole. Each side of the lower port is fixedly connected with each side of the hexagonal screw hole.

[0012] The sleeve 2 and the connector 6 ...

Abstract

The invention relates to a special tool for electrification fastening of a 10-kilovolt pin insulator. The tool comprises an insulation rod, external threads are opened in the upper portion of the insulation rod, an insertion head is arranged, the lower end of a connector is open, internal threads are formed in the lower end, and the lower end of the connector is screwed with the upper end of the insulation rod. an insertion head is arranged at the upper end of the connector, an insertion groove is formed in the lower end of a bushing, and a hexagonal screw hole is formed in the upper end and is covered with a nut cap. By means of the special tool, insulation fixation nuts can be fastened smoothly, and the special tool is high in working efficiency, convenient to use and applicable to aerial operation.

Description

technical field [0001] The invention relates to a special tool for fastening 10 kV pin insulators with electricity for fastening the pin insulator fixing nuts. Background technique [0002] When the pin insulator is installed, the bottom of the screw will be screwed to the fixing nut. Since the insulator is installed at a high position, it will be in the wind blowing state for a long time. During the process of the wind direction changing back and forth, the fixing nut will gradually loosen, which will cause the pin insulator to fall off. drop, affecting line operation. Regarding fastening the fixing nut in the prior art, a sleeve that can twist the fixing nut is installed on the top of the insulating rod, but due to the limited length of the insulating rod, it often happens that the distance between the operating position of the operator and the insulator is slightly It is longer than the length of the insulating rod. If the insulating rod is used for butt jointing, the le...
