For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of submarine cable continued access armouring wire to lay clamping and fixing device, including: diminished shaft, the most sliding rise block and pinching screw；The center of described diminished shaft is with manhole, and its periphery offers the groove of two row's annular arrangements；Described oblique cunning rise block be surface be the wedge of arc, each oblique cunning rises and is carved with two tapped through holes radially on block, said two tapped through hole coaxial line, described oblique cunning rise block inner surface axial on be carved with arcuate groove respectively along the both sides of said two tapped through hole place axis；Described pinching screw inserts in described tapped through hole, and with the groove fit on described diminished shaft；The rise wedge angle of block and described diminished shaft of described oblique cunning is 2～7 °.
In one preferred embodiment of this utility model, described groove is with the female thread coordinated with described pinching screw.
In one preferred embodiment of this utility model, the distance between described arcuate groove and said two tapped through hole place axis is that described oblique cunning rises the 1/6 of block inner surface width.
In one preferred embodiment of this utility model, the length of described arcuate groove rises the length of block equal to described oblique cunning, and its radius is the 1/3～3/4 of armouring wire radius.
In one preferred embodiment of this utility model, the described oblique cunning block one that rises has three pieces, and described each oblique cunning rises the block axial length length less than or equal to described diminished shaft.
The beneficial effects of the utility model are: this utility model one submarine cable continued access armouring wire lays clamping and fixing device, simple in construction, reasonable in design, it is by diminished shaft, the cooperation of the most sliding rise block and tightening screw, it is achieved that the wedge of armouring wire positions and is fixedly clamped；This utility model can exert a force respectively axially and radially going up, it is achieved that fix the overall clamping of armouring wire and force respectively for different fineness steel wire is fixed, easy to use, good fixing effect.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to Fig. 1 to 4, this utility model embodiment includes:
A kind of submarine cable continued access armouring wire lays clamping and fixing device, including: diminished shaft 1, the most sliding rise block 2 and pinching screw 3.
Described diminished shaft 1 is wedge axle, and its center band has manhole 11, and for running through the cable core of submarine cable, the periphery of diminished shaft 1 offers the groove 12 of two row's annular arrangements, and groove 12 is with female thread.
Described oblique cunning rise block 2 be surface be the wedge of arc, one has three pieces, is evenly distributed on the side face of described diminished shaft 1, and each oblique cunning rises the block axial length length less than or equal to diminished shaft.Each oblique cunning rises and is carved with two tapped through holes 21 radially on block 2, said two tapped through hole 21 coaxial line, on the inner surface axial of the most sliding block that rises, the both sides along two tapped through hole place axis are carved with arcuate groove 22 respectively, distance between arcuate groove and said two tapped through hole place axis is the most sliding the 1/6 of the block inner surface width that rises, the length of arcuate groove is equal to the length of the most sliding block that rises, and its radius is the 1/3～3/4 of armouring wire radius.This arcuate groove is used for laying armouring wire, prevents the superposition of steel wire.
Described pinching screw 3 inserts in the tapped through hole 21 that described oblique cunning rises on block 2, and with groove 12 threaded engagement on diminished shaft 1.
The rise wedge angle of block and described diminished shaft of above-mentioned oblique cunning is 2～7 °, less than the angle of angle of friction, prevents steel wire from pulling or loosens.
nullAbove-mentioned submarine cable continued access armouring wire lays assembling and the use of clamping and fixing device: with pinching screw respectively by the tiltedly sliding movable side face being uniformly connected to diminished shaft of block that rises，Cable core exposed for submarine cable termination is inserted in manhole from one end that diminished shaft diameter is less，The armouring wire of submarine cable is inserted respectively in the most sliding space rising between block and diminished shaft，Symmetrical expression screws the pinching screw near diminished shaft small diameter one end，And armouring wire moved and is fixed in the arcuate groove of the most sliding block that rises，Again screw the pinching screw near diminished shaft small diameter one end，Each armouring wire is made to strain in the axial direction，Symmetrical expression screws the pinching screw near diminished shaft larger diameter one end the most again，Power radially is applied to armouring wire，Make it be fixedly clamped，In the process，Also can screw degree according to what armouring wire diameter different adjusted pinching screws，To apply different bed knifes.Under normal circumstances, the diameter of armouring wire is the least, and the degree that screws of pinching screw more arrives, and the bed knife of applying is the biggest.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
