Abstract

The invention discloses an angle steel cross arm insulator screw rod stress application replacement device which comprises an angle steel cross arm clamp and a tractor. The angle steel cross arm clampcomprises a fixed seat, a locking block, a limiting block and a first screw. A hook claw part is arranged at the first end part of the fixed seat; a groove into which the first side plate part of theangle steel cross arm movably extends is formed between the hook claw part and the fixed seat; the first end part of the fixed seat is provided with a through groove towards the second end part; thelocking block is arranged on the first screw rod in a sleeving manner and is provided with a clamping part matched with the angle steel cross arm in a clamping manner; the limiting block is mounted atthe through groove of the fixed seat; the first end of the first screw extends out of the limiting block through the through groove, and a rod head is arranged at the first end, extending out of thelimiting block, of the first screw; the rod head and the locking block are used for clamping and fixing the fixed seat and the angle steel cross arm; the tractor comprises a screw rod assembly and a pull rod; the screw rod assembly comprises a second screw, a first nut and a handle. Installation and dismounting are simple, usage is convenient and insulator replacement efficiency is guaranteed.

Description

technical field [0001] The present application relates to the technical field of electric power operation, and in particular to an angle steel cross-arm insulator threaded mandrel force replacement device. 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 installation and disassembly of the existing replacement device ...
