Fig. 2 is a schematic diagram of a motion compensation platform of the offshore rig self-levelling systems of Fig. 1.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is further described.
Refer to Fig. 1, The embodiment provides a kind of offshore rig self-levelling systems, be positioned at a sea for leveling
Rig 30 on upper drilling platforms or drill ship 10, this rig 30 includes boring tower 31 and a drilling rod 32, this offshore rig self-regulated
Flat system includes motion compensation platform 50, hydraulic power system 60 and some sensors 90.
Seeing also Fig. 1 and Fig. 2, this motion compensation platform 50 includes base 51, motion compensation plate 52 and connects
Some motion compensation parts 53 between base 51 and motion compensation plate 52, in one embodiment, motion compensation part 53 is a liquid
Cylinder pressure or electric cylinder, it includes cylinder body 531 and a piston 532, piston 532 can slide in cylinder body 531 and with cylinder body 531
Inner wall sealing, the top of piston 532 stretches out cylinder body 531 and is connected on the downside of motion compensation plate 52 by hinge arrangement, piston 532
Top be connected with motion compensation plate 52 also by spherical hinge structure, then piston 532 can be movable relatively compensating plate 52 at three-dimensional space
In do and rotate at any angle.
The outside of cylinder body 531 bottom is connected to the top of base 51 by hinge arrangement or spherical hinge structure, then cylinder body 531 can
Respect thereto 51 does in three dimensions and rotates at any angle.
In the present embodiment, six motion compensation parts 53, and these six it are connected between motion compensation plate 52 and base 51
Motion compensation part 53 head and the tail are adjacent to be inclined between motion compensation plate 52 and base 51, i.e. first motion compensation part 53
The top of piston 532 be disposed adjacent on motion compensation plate 52 with the top of the piston 532 of second motion compensation part 53,
The bottom of the cylinder body 531 of two motion compensation parts 53 is disposed adjacent with the bottom of the cylinder body 531 of the 3rd motion compensation part 53
On base 51, the top of the piston 532 of the top of the piston 532 of the 3rd motion compensation part 53 and the 4th motion compensation part 53
It is disposed adjacent on motion compensation plate 52, the bottom of the cylinder body 531 of the 4th motion compensation part 53 and the 5th motion compensation part
The bottom of the cylinder body 531 of 53 is disposed adjacent on base 51, the top of the piston 532 of the 5th motion compensation part 53 and the 6th
The top of the piston 532 of motion compensation part 53 is disposed adjacent on motion compensation plate 52, the cylinder body of the 6th motion compensation part 53
The bottom of 531 is disposed adjacent on base 51 with the bottom of the cylinder body 531 of first motion compensation part 53；Then in original state
Time, the edge of two adjacent motion compensation parts 53 and base 51 constitutes a stable triangle, two adjacent motions
