Abstract
The invention discloses a universal joint device for ocean deepwater drilling, comprising an upper supporting plate and a lower supporting plate. A plurality of flexible elements are arranged between one side of the lower supporting plate and the upper supporting plate, a loading plate is arranged on the other side of the lower supporting plate, two ends of the flexible elements are connected with an upper fixing bracket and a lower fixing bracket, the upper fixing bracket is connected with the upper supporting plate, the lower fixing bracket is connected with the lower supporting plate; and all flexible elements are uniformly arranged and surrounded as a circle. The structure of each flexible element is that a plurality of steel rings are arranged in cylindrical synthetic rubber, and two ends of the cylindrical synthetic rubber are both fixed with a supporting pin. The device can realize the compensation or the balance of the deviation caused by the rocking of a platform from wave, ocean currents and the like in the process of transferring and recycling marine risers, thereby ensuring the stability of the marine riser strings in the process of mounting and dismounting.
Description
Technical field
The invention belongs to offshore oil drilling apparatus field technology, relate to a kind of universal joint device for ocean deepwater drilling.
Background technology
At present, design, the manufacturing technology of Offshore Drilling Riser system support equipment are in space state at home, wherein joint arrangement is one of crucial corollary equipment, the design feature of this device is at the connection of marine riser string, compensating offset and cushion load when installing and using, the suspension of marine riser when being applicable to the installation exercise of Offshore Drilling Riser of petroleum-type or non-petroleum-type and non-drilling condition.
Marine drilling platform (or ship) except that roll and pitch takes place, also produces the heave movement up and down with wave period under wave action.These motions will influence the safety of marine riser in installation, unloading process.The marine drilling joint arrangement is one of visual plant that ensures offshore oil drilling riser system normal group process of assembling, be installed in the rotating disk top of platform well drilling system, with the supporting use of drilling water-separation pipe chuck assembly, it mainly acts on is balance and slows down the oscillating motion that marine riser produces in installation process.
Summary of the invention
The purpose of this invention is to provide a kind of universal joint device for ocean deepwater drilling, be used for the connection of ocean deepwater drilling equipment marine riser string, compensating offset and cushion load when installing, balance is also slowed down the oscillating motion that marine riser produces in installation process.
The technical solution adopted in the present invention is, a kind of universal joint device for ocean deepwater drilling, comprise mounting plate and bottom plate, be provided with some flexible members between the one side of bottom plate and the mounting plate, all flexible members evenly are provided with and form a circle, the two ends of each flexible member are connected with upper holder and lower fixed frame, and upper holder is connected with mounting plate, and lower fixed frame is connected with bottom plate.
Universal joint device for ocean deepwater drilling of the present invention, its feature also is:
The circle diameter that described each lower fixed frame constitutes is greater than the circle diameter that each upper holder constituted, and promptly there are an angle in the installation axle center of all flexible members and mounting plate and bottom plate.
Described mounting plate and bottom plate are square configuration.
Described mounting plate and bottom plate are round-shaped.
The structure of described flexible member is, is provided with some steel rings in columniform synthetic rubber, all is fixed with supporting pin at columniform elastomeric two ends.
The invention has the beneficial effects as follows, compact conformation, reliable in function, simple to operate, can be used for compensating riser system transfer, in the removal process since wave to the waving and skew that ocean current etc. causes of platform, with guarantee the marine riser string install, stationarity in the unloading process.

Fig. 1 is the structural representation of joint arrangement of the present invention;
Fig. 2 is the A line of vision structural representation among Fig. 1;
Fig. 3 is the partial cross sectional views of flexible member in the joint arrangement of the present invention.
Among the figure, 1. flexible member, 2. upper holder, 3. lower fixed frame, 4. mounting plate, 5. bottom plate, 6. load plate, 7. connecting pin, 8. bolt, 9. supporting pin, 10. flexible member unit, 11. steel rings, 12. synthetic rubber.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, universal joint device for ocean deepwater drilling of the present invention, its structure is: comprise mounting plate 4 and bottom plate 5, some flexible members 1 are installed between one side of bottom plate 5 (installed surface) and the mounting plate 4, the another side of bottom plate 5 (bearing surface) is equipped with load plate 6, the two ends of each flexible member 1 are equipped with upper holder 2 and lower fixed frame 3, fixedly connected by bolt 8 between upper holder 2 and the mounting plate 4, fixedly connected by another group bolt 8 between lower fixed frame 3 and the bottom plate 5, all flexible members 1 evenly are provided with and form a circle, and the circle diameter that the circle diameter that each lower fixed frame 3 constitutes is constituted greater than each upper holder 2, promptly there are an angle in the installation axle center of all flexible members 1 and mounting plate 4 and bottom plate 5.
As Fig. 3, the structure of flexible member 1 is, in columniform synthetic rubber 12, be provided with some steel rings 11, two ends at columniform synthetic rubber 12 all are fixed with supporting pin 9, steel ring 11 (or reinforcing bar) provides intensity, synthetic rubber 12 provides flexing, the stationary positioned when supporting pin 9 is used for being connected with the two ends mount pad.When flexible member 1 is made, steel ring 11 (or reinforcing bar), high-performance synthetic rubber 12 and the supporting pin 9 of the sphere of many stacks can be formed by sulfuration or other method integral production.By said structure realize compensation (balance) marine riser transfer, in the removal process since wave to the waving and skew that ocean current etc. causes of platform, with guarantee the marine riser string install, stationarity in the unloading process.Supporting pin 9 can be a class or other form.
The advantage of joint arrangement of the present invention is: be made up of the agent structure with universal joint function and flexible member unit. 1), simple in structure, connect reliable. 2), adopt the flexible member syndeton, rotational stiffness is good, the motion of self adaptation all directions, damping and damping are good. 3), the agent structure bearing capacity is strong, operating maintenance is easy. Can be applied to well the drillng operation under various marine sites, the sea conditions, especially adapt to the deep-sea marine environment, have preferably economic performance and good Practical Performance.
