The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, hydraulic bearing type marine riser joint arrangement of the present invention is arranged between riser spider and rotating disk, comprise agent structure, pressure restraining element and hydraulic power system three parts, wherein agent structure is comprised of body 7 and connecting bolt 9 thereof, locating piece 8, chuck junction plate 1, fluid cylinder junction plate 2, body 7, locating piece 8, connects securing member 9 and forms base for supporting; Pressure restraining element is comprised of the axis of guide 3, sheath 4, guide holder 5, fluid cylinder 6; Hydraulic power system is comprised of hydraulic line 10, accumulator 11.Pressure restraining element is along the circumferential direction uniform, pressure restraining element and hydraulic power system synergy can effective compensation riser system because offshore boring island heave movement is applied to the axial load on chuck support plate 1, also can effectively slow down riser system release and be applied to the recoil load on chuck support plate 1.
With reference to Fig. 1, Fig. 2, the concrete structure of apparatus of the present invention is, comprises the body 7 of universal joint, at the lower end of body 7 excircle, is provided with a plurality of locating pieces 8, for implementing to be connected with rotating disk; It is six fluid cylinders 6 that the middle part wing plate (base plate) of body 7 is above installed with a plurality of fluid cylinder 6(embodiment along even circumferential), the piston axes of each fluid cylinder 6 is fixed with a guide holder 5, this guide holder 5 is connected with an axis of guide 3, and the exposed parts of each axis of guide 3 is provided with sheath 4 and protects; The upper end of all axis of guides 3 and fluid cylinder junction plate 2 are connected, and fluid cylinder junction plate 2 is fixedly connected with chuck junction plate 1 by bolt; The oil-in of all fluid cylinders 6 is all communicated with accumulator 11 by hydraulic line 10.
The deflection angle of the axis of guide 3 relative guide holders 5 is 0-15 °, and sheath 4 can play dustproof, etch-proof effect, the protection axis of guide 3, the application life of the prolongation axis of guide 3.
The relative universal joint central through hole of each fluid cylinder 6 is symmetrical.According to actual condition, the quantity of hydraulic cylinder can be 6, also can need to carry out quantity adjustment according to carrying.
Universal joint can be split-type structural, also can adopt monolithic construction.The body 7 of universal joint is two halves formula structure, by connecting bolt 9, is connected to one, and there is locating piece in body 7 lower ends outsides, can implement be connected with rotating disk, both guaranteed efficiently, when Fast Installation, has also guaranteed the quick, easy of maintenance, maintenance.
Accumulator 11 is communicated with the oil-in of all fluid cylinders 6, can stored energy, reduce and impact and guarantee the Stability Analysis of Structures under loaded state.Accumulator 11 makes more steadily safety of system operation, when raising the efficiency, also can reduce energy consumption, according to carrying size, accumulator 11 and additional gas cylinder can be coupled together simultaneously, increase the volume of available gas, better realize riser system and occur the compensation in axial load and horizontal deflection situation.
The operating principle of apparatus of the present invention is,
1) when the equipment such as Offshore Drilling Riser system are placed on when action is installed on chuck junction plate 1 etc., axial load is applied on chuck junction plate 1, fluid cylinder 6 piston-retraction now, the compressibility of employing accumulator 11 interior gases reaches the stability of mechanical property, guarantees that composite frame structure is stable under the state of large carrying.
2) when the equipment such as Offshore Drilling Riser system carry out release, can on chuck junction plate 1, apply recoil load, now accumulator 11 compensates pressure-bearing and changes by increasing gas volume, and driving fluid cylinder 6 pistons stretch out to reach the effect of dynamic equilibrium, the recoil load while effectively slowing down riser system release.
3) when riser system is carried out the states such as system installation in mode of suspension or on chuck assembly, by fluid cylinder 6 flexible, can compensate the impact on riser system of heave movement that offshore boring island produces due to ocean wave, and guarantee stability and the safety of riser system can slow down the shock loading that riser system release produces simultaneously.When Offshore Drilling Riser system is subject to the effect of ocean, ocean current and occurs being offset, the axis of guide 3 relatively guide holder 5 is done the deflection action of 0-15 °, can also carry wave force and be applied to outer year on marine riser.
