Abstract
The invention discloses a maintenance block for vertical twin bundled conductors, and solves the problems that the maintenance is difficult and potential safety hazards are caused because a longer distance is kept between upper and lower conductors when conventional maintenance blocks (mostly adopting a single-conductor-hitching-leg structure) suitable for vertical twin bundled conductors are used for conductor maintenance under the action of gravity. The maintenance block comprises support pillars on which pulley hitching leg components and sitting rack components are arranged, wherein the pulley hitching leg components comprise two vertically distributed hitching leg racks; two central shafts are respectively arranged in the two hitching leg racks in a penetrating manner; pulleys are arranged on both of the two central shafts; and a telescopic connection bar is connected between the two hitching leg racks. Owing to the dual-hitching-leg structure, the distance between upper and lower conductors can be stabilized, and the distance between the two hitching legs can be adjusted according to the distance between different conductors.
Description
[technical field]
The present invention relates to the high voltage line maintenance equipment technical field, refer to especially a kind of vertical double bundle conductor maintenance coaster.
[background technology]
Double bundle conductor is widely used in high voltage power transmission and transforming, at present, double bundle conductor mainly be divided into horizontal with rectilinear.Because double bundle conductor is exposed in the outdoor overhead, so need often it to be overhauled, and when carrying out this high-altitude line maintenance, need to use coaster, in the prior art, adopt the coaster that hangs on the single conductor for rectilinear double bundle conductor more, it is the double bundle conductor wire driving that uses in 200920209782.4 the disclosed a kind of transformer station of Chinese patent such as application number, during to the maintenance of vertical double bundle conductor, in order to prevent the staggered interference that causes of upper lower wire and to withdraw difficult problem, the coaster that this single conductor hangs can only hang on the lower wire, but coaster adds that maintainer's weight can be with the drop-down certain distance of lower wire, cause having very large spacing between the lower wire, affect the maintainer to the maintenance of upper conductor.For this reason, it is the disclosed vertical double bundle conductor hook of 200820130619.4 Chinese patent that application number is arranged, when overhauling, above-mentioned hook is carried by the maintainer, hook and coaster can be used, and are suspended on the lower wire to stablize the spacing between the two when overhauling by the maintainer.Although above-mentioned vertical double bundle conductor hook can be stablized the spacing of upper lower wire, and is very inconvenient when using, and needs the maintainer to carry, simultaneously, hook structure exists the possibility that breaks off relations to have potential safety hazard.
[summary of the invention]
