Abstract

The invention relates to the technical field of line replacement equipment, and discloses a special tool for replacing an overhead lightning conductor of a power transmission line, which comprises a bracket main body and an iron tower frame, an auxiliary bracket is arranged on one side of the bracket main body, fixing frames are arranged in the bracket main body and the auxiliary bracket, and hinges are arranged between the bracket main body and the auxiliary bracket; and fixing hoops are arranged at the top ends of the bracket main body and the auxiliary bracket, telescopic rods are arrangedbetween the bracket main body, and bases are arranged at the lower ends of the bracket main body and the auxiliary bracket. According to the special tool for replacing the overhead lightning conductorof the power transmission line, the bracket main body and the telescopic rod are assembled for use, so that the bracket main body is convenient to carry and transport and quick and convenient to assemble; and the base is matched with the top seat to stably fix the bracket main body on an iron tower, so that the influence of bolt loosening on the stability of the bracket main body can be effectively reduced, and the friction force borne by the lightning conductor in the traction process is reduced by utilizing the rolling of the ball in the arc-shaped groove.

Description

technical field [0001] The invention relates to the technical field of line replacement equipment, in particular to a special tool for replacing overhead lightning protection lines of power transmission lines. Background technique [0002] The lightning protection wire is also called the overhead ground wire. The lightning protection wire is made of iron. One or two are erected on the top of the tower for lightning protection of the cable on the top of the tower. The lightning protection wire is usually used in conjunction with the lightning protection net and the lightning rod. It is a facility to eliminate lightning strikes to protect buildings or instruments. In order to fully protect the cable at the top of the tower, the lightning protection line is generally erected along the entire line in the 110-220 kV line, so as to prevent lightning. The line is connected across the tower, but once the lightning protection line is damaged, it is necessary to perform a large-scale ...
