Abstract

The invention discloses a channel steel cross arm insulator screw rod stress application replacement device which comprises a channel steel cross arm clamp and a tractor. The channel steel cross arm clamp comprises a fixed seat and a claw; the fixing seat is provided with an abutting part which movably contacts and abuts against a top of the channel steel cross arm; a first end of the claw is hinged to the first end, close to the abutting part, of the fixing seat, and a second end of the claw is provided with a hook part matched with the first side plate part of the channel steel cross arm; the second end of the fixed seat extends out of the channel steel cross arm in the direction away from the claw; the tractor comprises a screw rod assembly and a pull rod; the screw rod assembly comprises a screw, a nut and a handle; the first end of the screw upwards penetrates through the fixed seat to extend out of the channel steel cross arm, and the second end is connected with the first end ofthe pull rod; the pull rod is connected with a wire through a connecting piece; the nut rotatably sleeves a shaft section, extending out of the channel steel cross arm, of the screw and is in threaded fit with the screw, and a bottom of the nut abuts against the top of the fixing seat; and the handle is connected with the nut and used for driving the nut to rotate. Installation and dismounting are simple and usage is convenient.

Description

technical field [0001] The present application relates to the technical field of electric power operation, and in particular to a device for replacing channel steel cross-arm insulator screw rods with force. Background technique [0002] The replacement of linear insulators occurs frequently in the daily maintenance of transmission lines, and the replacement of insulators needs to be completed through corresponding replacement devices. The existing insulator replacement device mainly includes a fixing jig fixed on the cross arm and a pulling device installed on the fixing jig. In the replacement operation, the fixing fixture is first installed on the cross arm of the pole tower, and then the wire is pulled by the pulling device installed on the fixing fixture, and the insulator string is pulled upward to facilitate the connection between the cross arm and the wire. Replacement of insulator strings. However, the existing replacement device for the channel steel cross-arm is...
