The invention belongs to the field of special tools for lightning conductors and relates to a special tool is used for repairing the overhead lightning conductor of a power transmission line. When a single wire of an existing lightning conductor is disconnected, the maintenance of the lightning conductor is inconvenient, and a plurality of electricians are required to perform fixing operation; a disconnected position is hoisted manually or through hoisting equipment, so that the disconnected position is not stressed and can be repaired, and as a result, the problem of complex operation is brought about. The invention aims to solve the above problem. The special tool comprises a fixing seat; a fixing groove is formed in the bottom end of the fixing seat; fixing brackets are symmetrically and movably arranged in the fixing groove; the fixing brackets extend out of the fixing seat; fixing though holes are formed in the fixing brackets; full-thread double-screw bolts are movably arranged in the fixing though holes. The special tool has the advantages of reasonable structure, low production cost and convenient operation. With the special tool adopted, the lightning conductor can be clamped and stretched at the same time; convenience is brought to electricians to replace and maintain a disconnected position, and working efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of special tools for lightning protection wires, in particular to a special tool for repairing overhead lightning protection wires of power transmission lines. Background technique [0002] Lightning conductors refer to conductors installed to lead lightning into the ground in order to protect equipment and avoid lightning strikes. Also known as lightning protection line. The lightning conductor is made of iron, the lightning conductor is copper (or silver), the top of the lightning conductor faces the sky, the lightning conductor is connected to the lightning net and buried in the ground, and the lightning conductor is connected to the lightning conductor. The buried lightning protection net is a facility to eliminate lightning strikes and protect buildings or instruments. After installation, the lightning protection line may be damaged due to its own gravity or the influence of the wind, resulting in an o...
