Line lifting Work tool can be divided into fastening means from top to bottom（U-shaped ring）, load supporting system（Hanging belt, insulating bar), lifting wire dress
Put（Lever Blocks, hydraulic rockshaft）, the eight division elements such as line lifters.The utility model is carried out mainly for eight division line lifters
Design.
During design Work tool, should be tried one's best on the basis of Work tool security is considered and simplify the structural shape of Work tool.This
The division line lifter of extra-high voltage eight that utility model is proposed, is designed as split-type structural on the basis of monolithic construction, is easy to existing
The constructing operation of field, line lifter split-type design includes two parts altogether：1st, force bearing plate：The eight main load portions of division line lifter
Point, it is desirable to possess certain bearing capacity, for the ease of using, force bearing plate may be designed as using triangle or trapezoidal flat board；
2nd, wire support device：Including eight wire lifting pawls, the main enhanced feature for being responsible for wire during maintenance wire, which part
（Such as 2,4 or 6）It is arranged on force bearing plate, another part is used and is releasably connecting at force bearing plate lower section.To be conducive to
Balance, preferably by symmetrical design.Further, four wire lifting pawls are arranged on force bearing plate, on force bearing plate
Side respectively lifts a wire, and four wire lifting pawls are each below force bearing plate using force bearing plate lower section is releasably connecting at
One wire of lifting, it is so more balanced.
Referring to Fig. 1, the utility model is provided at the split conductor line lifter a total of 8 of 1000kV UHV transmission lines eight
