Novel porcelain stick suspension string lifting tool for power transmission line

Abstract

The invention relates to a lifting tool,and discloses a novel porcelain stick suspension string lifting tool for a power transmission line. The lifting tool comprises an assembling frame upper cover and an assembling frame lower cover,the assembling frame upper cover and the assembling frame lower cover jointly form an assembling frame,and the assembling frame upper cover and the assembling framelower cover are connected through a detachable connecting component; the ends of the assembling frame upper cover and the assembling frame lower cover in the length direction are each fixedly providedwith a bearing plate,and the two bearing plates jointly form a bottom end plate of the assembling frame; the four inner side faces of the assembling frame are each fixedly provided with a linear wooden plate with one end abutting against the bearing plate,and the linear wooden plates are detachably fixed to the inner side face of the assembling frame. The whole string porcelain stick can form a whole,meanwhile,porcelain stick transfers stress is eliminated,the porcelain stick is prevented from being broken during tension line erection and accessory installation construction,and then personalsafety accidents are avoided.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a novel hoisting tool for hanging strings of porcelain rods used in power transmission lines. Background technique [0002] At present, AC long rod-shaped porcelain insulators are widely used in power transmission and transformation lines. Uncertain factors exist in the product quality and transportation process, which makes the AC long rod-shaped porcelain insulators have damage that cannot be discerned in appearance. The whole hoisting is connected with the hanging fittings and the pulley. When the tensioned wire runs over the pulley, the horizontal stress will cause the whole string to tilt. After rebounding, there will be a risk of porcelain rod breakage. At present, it is necessary to do a good job of secondary protection or the later attachment before hanging The construction method is mainly used, and risk factors exist. Contents of the invention [0003] The invention aims at the pro...

Problems solved by technology

[0002] At present, AC long rod-shaped porcelain insulators are widely used in power transmission and transformation lines. Uncertain factors exist in product quality and transportation, which makes AC long rod-shaped porcelain insulators have unrecognizable damage.

The whole hoisting is connected with the hanging fittings and the block. When the tensioned wire passes the block, the horizontal stress will cause the whole string to tilt. After the rebound, there will be a risk of the porcelain rod breaking. At present, the secondary protection or the later attachments are used for hanging. The main method of construction is construction, and there are risk factors
