Bearing tool.For 800 kilovolts of transmission pressures, it is necessary to which a kind of can be used for 800 KV distribution circuit electrified replacing linear towers to hang
Play the thread-lifting hook of lifting six-multiple conductor during vertical insulator monolithic/bunch of insulator, metal yoke plate, fixture etc..In order to full
Requirement in sufficient intensity, makes of titanium alloy in the market.The instrument weighs 25 kilograms, has reached operating personnel
Can load the limit.Therefore, develop light and can reach that the six line thread-lifting hooks for changing large-tonnage insulator intensity requirement have
There is higher use value.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of lightweight that can lift 800 kilovolts of six-multiple conductors, high-strength
The line thread-lifting hook of carbon fiber extra-high voltage six.
In order to solve the above-mentioned technical problem, the line thread-lifting hook of carbon fiber extra-high voltage six that provides of the present invention, by a main body and
Two secondary thread-lifting hooks compositions, described main body and secondary thread-lifting hook described in two are by carbon fiber prepreg through hot-forming, institute
Many piece connection pillar groups of the main body stated between entablature, sill and the described entablature of connection and described sill
Into the two ends of described entablature and described sill are equipped with thread-lifting hook, and one is provided with the middle and upper part of described entablature
The individual upper screw for being connected with thread-tightening lead screw, described sill is used for what is be connected with described secondary thread-lifting hook provided with two
Lower screw, the secondary thread-lifting hook described in two is connected with the lower screw described in two of the described sill of described main body by bolt
Connect.
The distance of lower screw described in two is 500mm, and the lower screw described in two is apart from end hanging wire midpoint distance
250mm。
The thread-lifting hook outer ledge of described thread-lifting hook and described secondary thread-lifting hook wants at least 30mm on the inside of high outlet hook
Highly.
Described main body and described secondary thread-lifting hook carry out chamfered.
The diameter of described upper screw and described lower screw is slightly larger than the diameter for the bolt being attached thereto.
The top of described secondary thread-lifting hook and the lower section of described sill contact point carry out designed arc-shaped appearance.
Using the line thread-lifting hook of carbon fiber extra-high voltage six of above-mentioned technical proposal, matrix material is high intensity, high-modulus carbon fibre
Dimension, by carbon fiber prepreg through hot-forming.Matrix is set in the case where intensity meets requirement using completely or partially hollow
Meter, hollow position is filled by high intensity inserts.
The present invention is applied to operating personnel and is changing 800 KV transmission line tangent tower suspension insulators, metal yoke plate, card
Used during the operations such as tool.Using said apparatus, it on the one hand can mitigate the labor intensity of operating personnel significantly, make operation more just
It is prompt；On the one hand the security of operation can be improved；One side thread-lifting hook is designed using two-piece unit, is easy to thread-lifting hook to be passed from ground
Deliver on tower；The auxiliary hook of one side thread-lifting hook makes auxiliary hook have certain swing angle with using designed arc-shaped appearance at body contact；
In addition, the applied temps scope for changing thread-lifting hook is wide, corrosion resistance is strong.
In summary, the present invention is a kind of lightweight that can lift 800 kilovolts of six-multiple conductors, high-strength carbon fiber extra-high voltage
Six line thread-lifting hooks.
