By receiver bracket 7, the driving force input mechanism 8 installed in the lower surface of receiver bracket 7 rotated.Motor 27 drives worm screw 31
Rotate, and then coordinated using worm screw 31 and driving force input mechanism 8 and realize power transmission, so as to drive receiver bracket 7, you can
Belt track lifting mechanism 3 is driven to rotate.
The driving force input mechanism 8 is worm gear.
On the spring Flat belt 1 the equally distributed 1a with holes of some rows is provided with along the length direction of spring Flat belt 1；
Uniformly be provided with the flute profile spring 2 can occlusion corresponding with 1a with holes tooth 2a.Process of the flute profile spring 2 in rising
In new tooth 2a is bitten on spring Flat belt 1 in new 1a with holes, you can realize the constantly soaring of spiral cylinder.
The belt track lifting mechanism 3 includes lifting cylinder 3a, is set on lifting cylinder 3a along the axis direction of itself
Have for lifting spacing roller 3b that is being oriented to and forming double helical arrangement to flute profile spring 2.Double helical arrangement
On two spacing roller 3b coordinated in pairs between spacing be more than flute profile spring 2 thickness.The flute profile spring 2 exists
Lifting cylinder 3a revolving force is lifted up under driving along the spacing roller 3b of double helical arrangement.Present invention employs double
The guiding that the spacing roller 3b of helical arrangement is lifted to flute profile spring 2, is effectively prevented flute profile spring 2 and is lifting
During rock and misplace, ensure that the accuracy and stability of motion, so can just make tooth 2a it is corresponding with 1a with holes occlusion.
The spring Flat belt 1, flute profile spring 2 are made of stainless steel or two-phase steel material.
Due to using the possibility needed in view of corrosion on naval vessel, therefore shaft coupling of the present invention 25 uses stainless steel
Material is made.
Also, corrosion-inhibiting coating is made on the receiver 6, spring Flat belt 1, the surface of flute profile spring 2, and the anti-corrosion applies
Layer is nano metal coating, and the nano metal coating is nanocrystalline nickel coating, so as to play protective action to itself, is extended
The service life of equipment.
The lifting cylinder 3a is arranged on stress support staving 5 upper end, the spacing roller 3b can around with lifting post
Body 3a junction rotates.
The spacing roller 3b is roller bearing.
The upper end of receiver bracket 7 is circumferentially uniformly provided with several and is used to match somebody with somebody with the bottom of receiver 6
The receiver bottom bearings 14 of conjunction.Several are uniformly disposed with the circumferencial direction of the receiver 6 and is arranged on receiver
The receiver external bearings frame 13 of the upper end of bracket 7.The benefit of such structure design is：Ensure that receiver 6 can be flat with spring
The elastic strength of flat rubber belting 1 arbitrarily rotates.
The rail-guided frame 4 includes distribution coaxial with belt track lifting mechanism 3 and in the outrigger 4c of non-close ring-type, edge
Outrigger 4c madial wall uniform spiral distribution and pitch and several blocks of the pitch identical of spiral cylinder 4d.
Further, the block 4d staggers is engaged position and flat with spring on spring Flat belt 1 with flute profile spring 2
Offseted with 1 lateral surface, can make spring Flat belt 1 progressively close to flute profile spring 2 using block 4d and finally make spring flat
Flat rubber belting 1 is interlocked with flute profile spring 2.
The outrigger 4c is provided with breach 102, during track leading truck 4 rotates, the spring in receiver 6
Flat belt 1 may pass through breach 102 and enter in rail-guided frame 4, and so as to be engaged with flute profile spring 2, structure design is closed
Reason, will not cause to interfere in motion process.
The axis for the cylindricality that the flute profile spring 2 stacks overlaps with the axis of stress support staving 5.The tooth of the present invention
After type spring 2 is stacked together, the tooth of the tooth 2a in each pitch and the same position in adjacent pitch is in vertical direction
