Utility model content
Technical problem to be solved in the utility model is to provide a kind of can mention the lightweight of 800 kilovolts of six-multiple conductors, high-strength carbon fiber extra-high voltage six line thread-lifting hook.
In order to solve above-mentioned technical problem, the carbon fiber extra-high voltage six line thread-lifting hook that this utility model provides, it is made up of through hot-forming secondary thread-lifting hook carbon fiber prepreg through hot-forming main body and two carbon fiber prepreg by one, described main body is by entablature, many between entablature and described sill described in sill and connection are connected pillar composition, the two ends of described entablature and described sill are equipped with thread-lifting hook, one it is provided with for the upper screw being connected with thread-tightening lead screw in the middle and upper part of described entablature, described sill is provided with two for the lower screw being connected with described secondary thread-lifting hook, two described lower screws of the described sill of two described secondary thread-lifting hooks and described main body are connected by bolt.
The distance of two described lower screws is 500mm, and two described lower screw distance end hanging wire midpoint distances are 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 slightly larger than the diameter of the bolt being attached thereto.
The top of described secondary thread-lifting hook carries out designed arc-shaped appearance with the lower section of described sill contact point.
Using the carbon fiber extra-high voltage six line thread-lifting hook of technique scheme, matrix material is high intensity, high modulus carbon fiber, by carbon fiber prepreg through hot-forming.Matrix, in the case of intensity meets requirement, uses all or part of hollow design, and hollow position is filled by high intensity inserts.
This utility model is applicable to operating personnel and uses when changing the operations such as 800 KV transmission line tangent tower suspension insulators, metal yoke plate, fixture.Use said apparatus, on the one hand can significantly alleviate the labor intensity of operating personnel, make operation more convenient；On the one hand the safety of operation can be improved；On the one hand thread-lifting hook uses two-piece unit design, it is simple to thread-lifting hook is sent to tower from ground；On the one hand use designed arc-shaped appearance at the auxiliary hook of thread-lifting hook and body contact, make auxiliary hook have certain pendulum angle；Additionally, the applied temps scope changing thread-lifting hook is wide, corrosion resistance is strong.
In sum, this utility model is a kind of to mention the lightweight of 800 kilovolts of six-multiple conductors, high-strength carbon fiber extra-high voltage six line thread-lifting hook.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it is made up of the secondary thread-lifting hook 7 of a main body 8 and two, main body 8 and two secondary thread-lifting hooks 7 by carbon fiber prepreg through hot-forming, main body 8 is by entablature 1, between sill 2 and connection entablature 1 and sill 2, 4 connection pillars 6 form, the two ends of entablature 1 and sill 2 are equipped with thread-lifting hook 3, one it is provided with for the upper screw 4 being connected with thread-tightening lead screw in the middle and upper part of entablature 1, sill 2 is provided with two for the lower screw 5 being connected with secondary thread-lifting hook 7, two secondary thread-lifting hook 7 screws 5 lower with two of the sill 2 of main body 8 are connected by bolt.
The distance of two lower screws 5 is 500mm, and two lower screws 5 are 250mm apart from end hanging wire midpoint distance.
In order to prevent wire in operation process from being swung by thread-lifting hook, the thread-lifting hook outer ledge of thread-lifting hook 3 and secondary thread-lifting hook 7 wants the height of at least 30mm inside high outlet hook.In order to reduce wire abrasion, main body 8 and secondary thread-lifting hook 7 will carry out chamfered.The diameter of upper screw 4 and lower screw 5 is all slightly larger than the diameter of the bolt being attached thereto.Secondary thread-lifting hook 7 top carries out designed arc-shaped appearance with the lower section of sill 2 contact point, makes the single thread-lifting hook in two, the latter half have certain swing nargin.
