Abstract

The invention provides a light lifting tool for transmission line hot-line work. The light lifting tool comprises a lifting tool main body and a carbon fiber lifting appliance, wherein the carbon fiber lifting appliance comprises a carbon fiber lifting rod, an upper armor clamp and a lower armor clamp; a lifting hole is formed in the middle position of the upper part of the lifting tool main body,the lifting hole is connected with an insulation lifting rod, conducting wire grooves are symmetrically formed in the upper edges of both sides of the lifting hole, and a preset number of mounting holes are uniformly formed in the lower part of the lifting tool main body; and the mounting holes are connected with the upper armor clamp, the lower armor clamp is arranged just below the upper armorclamp, the lower armor clamp is connected with the upper armor clamp by virtue of the carbon fiber lifting rod, and the lower armor clamp is used for placing bundled conductors. The light lifting toolis provided with the lifting tool main body, the upper armor clamp and the lower armor clamp, by adopting the split structure, the structure is simple, the weight is light, the installation is convenient, and the mechanical strength meets the requirement.

Description

technical field [0001] The invention relates to the technical field of wire lifting tools, in particular to a lightweight wire lifting tool for live work on transmission lines. Background technique [0002] At present, in EHV and UHV transmission lines, wire lifting tools are required to replace string insulators of wire insulators such as six-split or eight-split insulators. The wire lifting tool is connected to the cross arm of the transmission pole through the hydraulic screw and the insulating pull rod, and the weight of the wire is temporarily transferred from the insulator string to the wire lifting tool and the insulating pull rod to realize the replacement of the insulator string. [0003] UHV AC transmission lines constructed in my country adopt 8×630mm 2 , the sub-conductor spacing is generally 400mm or 450mm, and the ±800kV UHV DC transmission line adopts 6×720mm 2 , 6×1250mm 2 , ± 1100kV UHV DC transmission line adopts 8×1250mm 2 , compared with 500kV or 750k...
