Problems solved by technology

[0005] After on-site investigation, the defects of loose fitting bolts in the live parts are mainly the second type of bolts. The nuts of this type of bolts basically do not need to be strengthened, and the anti-loosening depends on the closed pin. The nuts will also loosen quickly, and individual hardware bolts will also fall off

Abstract

The invention provides a fitting bolt ground potential assembling and disassembling combination tool. The tool comprises an insulating bar and an installation head. The insulating bar comprises an installation seat. The installation seat is located at the front end of the insulating bar and is of a disc structure, the circumferential side of one plane of the installation seat is provided with gear teeth and grooves, the gear teeth and the grooves are arranged at intervals and are identical in shape, and an installation hole is formed in the middle of the installation seat. The installation head comprises a connecting part, the connecting part and the installation seat are identical in structure, and the connecting part and the installation seat can be meshed. By the adoption of the scheme, maintenance and overhauls can be conducted under the condition that a line is electrified.

Description

[0001] technical field [0002] The invention relates to the field of electric power maintenance, in particular to a combination tool for loading and unloading ground potential of metal bolts. [0003] Background technique [0004] In high-voltage transmission line equipment, bolts are one of the most common materials. They have multiple functions such as connection, fixation, and load bearing. Once there is a problem with the bolts, it will directly affect the overall safety level of transmission line equipment. The bolts of live parts fittings are mainly divided into two categories: one is fastening bolts, which are mostly used for the flow connections of various clamps; the other is connection bolts, which are mostly used for connection and steering of various fittings. These two types of bolts. The first type of bolts are mainly used in conjunction with nuts. The nut and the screw are tightly connected and spring washers are used as a measure to prevent the nut from loo...
