Abstract
The special arc pin pulling pliers for electrified maintenance of the power transmission line are characterized in that an arc hook with a forward bow back is arranged on a lower operating handle after a jaw of the existing pin pulling pliers. The beneficial effects of the utility model are that, only need the arc to collude when getting to take off the ann commentaries on classics and block the insulator bowl head and remove, the arc colludes and just in time agrees with the bowl head and stabilizes, and personnel also need not adjust the station position to reduce time and risk improve work efficiency.
Description
Technical Field
The utility model discloses special arc of transmission line electrified maintenance pulls out round pin pincers.
Background
The existing tool is a pin pulling clamp for an operating rod of live-line operation of a power transmission line, and the pin pulling clamp is arranged on an insulating operating rod in the process of replacing a 110-plus-220 kV power transmission line linear tower insulator in live-line mode and is used for taking out an insulator M pin in a linear tower ground potential operation mode, and the tool plays an auxiliary role in restoring the connection of an installed insulator string. But the efficiency is low and the stability is poor. In the process of replacing the 110-plus-220 kV transmission line linear pole tower insulator in an electrified way, the existing pin pulling pliers cannot meet the fixing and stabilizing effect when the insulator string connection is restored to be installed, the efficiency is low in use, and the stability is poor.
Disclosure of Invention
The special arc pin pulling pliers for electrified maintenance of the power transmission line are characterized in that an arc hook with a forward bow back is arranged on a lower operating handle after a jaw of the existing pin pulling pliers.
The arc colludes the welding and colludes the department of 30mm behind the operating handle apart from the pincers mouth under, and the arc colludes for circular reinforcing bar, and the diameter is established to 80 mm.
The arc hook of the utility model is arc-shaped.
Arc colludes circular arc length and is 250 mm.
The beneficial effects of the utility model are that, only need the arc to collude when getting to take off the ann commentaries on classics and block the insulator bowl head and remove, the arc colludes and just in time agrees with the bowl head and stabilizes, and personnel also need not adjust the station position to reduce time and risk improve work efficiency.

Detailed Description
According to the special arc-shaped pin pulling pliers for electrified maintenance of the power transmission line, an arc-shaped hook with a forward bow back is arranged on the lower operating handle after the mouth of the existing pin pulling pliers.
The arc colludes the welding and colludes the department of 30mm behind the operating handle apart from the pincers mouth under, and the arc colludes for circular reinforcing bar, and the diameter is established to 80 mm.
The arc hook of the utility model is arc-shaped.
Arc colludes circular arc length and is 250 mm.
Insulator chain is in the form of dangling, there is certain skew angle wire and insulator chain in the actual line, when changing the operation of transmission line insulator with electricity, need extract insulator M round pin through the pin pulling pincers on the insulating bar, then need swing insulator chain and just can get and take off insulator chain and be connected with the wire (bowl head and bulb), former get take off or install insulator chain and wire connection need use current pin pulling pincers, original pin pulling pincers are difficult to block the insulator and remove, because of pin pulling pincers itself is movable, the pin pulling pincers itself can not fix the insulator bowl head, often slide. The personnel station position on the tower needs to be adjusted at multiple angles to be fixed, so that certain risks are increased when the personnel transfer the position. According to the size and the model of the insulator, an arc hook is arranged on the original pin pulling pliers according to the structure of the pin pulling pliers, and the arc radian and the length of the arc are finally determined to be 250mm through field use.
