At present, domesticly only preliminary exploration is carried out to UHV transmission line live line working, continued the operating type of extra high voltage network live line working, in Work tool, only improved in the size and structure of instrument.Extra-high voltage electrified operation does not also form perfect operational method and simple and convenient power tool, the bearing tool especially when changing large-tonnage insulator.For 800 kilovolts of transmission pressures, need a kind of thread-lifting hook playing the effect of lifting six-multiple conductor when can be used for 800 KV distribution circuit electrified replacing linear tower suspension insulator monolithic/bunch of insulator, metal yoke plate, jig etc.In order to meet the requirement in intensity, be make of titanium alloy in the market.This instrument weighs 25 kilograms, reached operating personnel can the limit of load.Therefore, develop light and the six line thread-lifting hooks changing large-tonnage insulator requirement of strength can be reached there is higher use value.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly can mention the lightweight of 800 kilovolts of six-multiple conductors, high-strength carbon fiber ultra high voltage six line thread-lifting hook.
In order to solve the problems of the technologies described above, carbon fiber ultra high voltage six line thread-lifting hook provided by the invention, be made up of a main body and two secondary thread-lifting hooks, described main body and the secondary thread-lifting hook described in two by carbon fiber prepreg through hot-forming, described main body is by entablature, sill and connect described in entablature and described sill between many connecting struts form, the two ends of described entablature and described sill are equipped with thread-lifting hook, a upper screw for being connected with thread-tightening lead screw is provided with in the middle and upper part of described entablature, described sill is provided with two lower screws for being connected with described secondary thread-lifting hook, the lower screw described in two of the described sill of the secondary thread-lifting hook described in two and described main body is connected by bolt.
The distance of the lower screw described in two is 500mm, and the lower screw distance end hanging wire mid point distance described in two is 250mm.
The thread-lifting hook outer ledge of described thread-lifting hook and described secondary thread-lifting hook wants the height of at least 30mm inside high outlet hook.
Described main body and described secondary thread-lifting hook carry out chamfered.
The diameter of described upper screw and described lower screw is all a bit larger tham the diameter of the bolt be attached thereto.
Designed arc-shaped appearance is carried out in the top of described secondary thread-lifting hook and the below of described sill contact point.
Adopt the carbon fiber ultra high voltage six line thread-lifting hook of technique scheme, basis material is high strength, high modulus carbon fiber, by carbon fiber prepreg through hot-forming.Matrix, when intensity meets the demands, adopts all or part of hollow design, and hollow position is filled by high strength inserts.
The present invention is applicable to operating personnel and uses when operations such as replacing 800 KV transmission line tangent tower suspension insulator, metal yoke plate, jigs.Adopt said apparatus, greatly can alleviate the labour intensity of operating personnel on the one hand, make operation more convenient; The fail safe of operation can be improved on the one hand; Thread-lifting hook adopts two-piece unit design on the one hand, is convenient to thread-lifting hook and is sent to tower from ground; Auxiliary hook and the body contact place of one side thread-lifting hook adopt designed arc-shaped appearance, make auxiliary hook have certain pendulum angle; In addition, the applied temps scope changing thread-lifting hook is wide, and corrosion resistance is strong.
In sum, the present invention a kind ofly can mention the lightweight of 800 kilovolts of six-multiple conductors, high-strength carbon fiber ultra high voltage six line thread-lifting hook.
