Abstract
The invention relates to an insulating hook, which comprises a hook main body, wherein a movable hook safety lock is arranged on the hook main body and a safety unlocking rope is connected with the lower part of the hook. The insulting hook has the beneficial effects that the structure is reasonable; an electrified wire can be directly hitched without repeated expansion and contraction of an insulating arm; the work efficiency and the safety coefficient are improved.
Description
Technical field
The present invention relates to distribution engineering field, especially a kind of hot line work dedicated lifting hook.
Background technology
Distribution network live line work three class-charged group founds straight line pole project, the flexible number of times relating to bucket arm vehicle in the process of wire lifting is frequent, to hot line work produce bring a lot of unfavorable: the first, the frequent flexible time namely extending operation of bucket arm vehicle, have impact on again the state of mind of operating personnel; The second, hot line work is originally exactly high-risk operations, and the frequent flexible of bucket arm vehicle makes operating personnel's continuous print between charged body all shuttle back and forth, and adds the danger coefficient of operation; 3rd, the frequent of bucket arm vehicle stretches, and exacerbates the wearing and tearing of insulation arm, adds the maintenance cost etc. of bucket arm vehicle.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and providing a kind of can directly mount live wire and insulation arm need not be made to repeat the cargo hook gear stretched.
The present invention solves the technical scheme that its technical matters adopts: this insulation suspension hook, comprises main hook part, and main hook part is provided with a mobilizable shackle bolt lock, is connected with one section of insurance unlock rope below shackle bolt lock.
As preferably, be provided with a hollow section below described main hook part, be provided with two fixed pulleys in hollow section, insurance unlock rope walks around this two fixed pulleys respectively.
As preferably, described shackle bolt lock is provided with a torsion spring.
As preferably, described main hook part adopts epoxide resin material.
Inventing useful effect is: the present invention is rational in infrastructure, can directly mount live wire and insulation arm need not be made to repeat to stretch, improve work efficiency, and improve safety factor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Description of reference numerals: main hook part 1, shackle bolt lock 2, insurance unlock rope 3, hollow section 4, fixed pulley 5, torsion spring 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment: as Fig. 1, a kind of insulation suspension hook, comprises main hook part 1, adopts epoxide resin material, bearing when lifting by crane as live wire.Main hook part 1 is provided with a mobilizable shackle bolt lock 2, prevents coming off of live wire in lifting process, is connected with one section of insurance unlock rope 3 below shackle bolt lock 2.Be provided with a hollow section 4 below main hook part 1, be provided with two fixed pulleys 5 in hollow section 4, insurance unlock rope 3 walks around this two fixed pulleys 5 respectively.
In the normal state, shackle bolt lock 2 makes main hook part 1 close, and by pulling insurance unlock rope 3, drives shackle bolt lock 2 to make the open unblock of main hook part 1.Shackle bolt lock 2 is provided with a torsion spring 6, and shackle bolt lock 2 can be made to automatically reset.
During use, insurance unlock rope 3 one end is fixed on shackle bolt lock 2 place, and one end is placed on damp proofing of ground pad, and time below live wire to sag position, ground electrician pulls open insulation shackle bolt lock 2 by insurance unlock rope 3 makes live wire depart from suspension hook.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
