Technical field
The utility model relates to a kind of oil drilling platform boring tower mobile device, and it belongs to the oil drilling platform apparatus field.
Background technology
Self-elevating drilling platform is the basic drilling well facility that carries out the marine oil field drilling operation, is made up of platform main hull, liftable spud leg and the semi girder that can do to move forward and backward on Platform Deck.The semi girder tail end is equipped with boring tower, and when semi girder moves when stretching out outside the offshore boring island stern backward, its boring tower is in outside the stern end, and rig is in the operating position, can carry out drillng operation.When semi girder moves forward, when making boring tower partly be recovered to the hull tail end, rig is in the Platform Deck top, and platform is in non-drillng operation state.Therefore, boring tower need have the vertical and horizontal locomotive function, to realize the adjustment of drilling well position.The method that adopts usually that moves of self-elevating drilling platform boring tower position is now: longitudinally establish intermeshing slideway with the semi girder soffit on Platform Deck, with the cylinder pushes semi girder, whole semi girder can be moved forward and backward, thereby realize vertically moving of boring tower; Plane and boring tower bottom surface with the cylinder pushes boring tower, are realized laterally moving of boring tower along laterally establishing intermeshing slideway on the semi girder tail end.The shortcoming of this move mode is: travel mechanism divides two-layer up and down, complex structure; When boring tower along laterally moving when making boring tower position deviation semi girder longitudinal centre line because semi girder bears eccentric load, its supporting capacity descends, and the boring tower top hook load of sign drilling duty is reduced, drilling depth reduces.
Summary of the invention
For the boring tower that overcomes existing oil drilling platform moves the problem of existence, the utility model provides a kind of oil drilling platform boring tower mobile device, and this boring tower mobile device should simple in structure, reliable operation; Under any circumstance, semi girder can not bear eccentric load, thereby improves the drilling duty of platform.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of oil drilling platform boring tower mobile device, and it mainly comprises offshore boring island, boring tower and a semi girder, semi girder one end that boring tower is housed can reach the outside of offshore boring island.It also comprises a movable support bracket, and movable support bracket is by four bracket bases, two pallet stringers and two quadras that the carriage crossbeam is formed, and bracket base is positioned at four jiaos of quadra.Bottom at bracket base is provided with horizontal concrete chute, and horizontal concrete chute matches with two carriage glide paths that are fixed in the offshore boring island afterbody, respectively is provided with a horizontal mobile device in the carriage crossbeam; Be provided with vertical chute on the top of bracket base, vertically chute matches with two carriage sliding ways that are positioned at the semi girder bottom, respectively is provided with a longitudinal moving device in pallet stringer.In the horizontal concrete chute of bracket base bottom, be provided with liner and lower liner; In vertical chute on bracket base top, be provided with liner and lower liner.Longitudinal moving device is fixed on the pallet stringer through otic placode and ratchet bearing, is provided with ratchet holes on the base plate of carriage sliding way, and ratchet holes matches with ratchet.Horizontal mobile device is fixed on the carriage crossbeam through otic placode and ratchet bearing, is provided with ratchet holes on the panel of carriage glide path, and ratchet holes matches with ratchet.
The guiding theory of technique scheme is: because movable support bracket is a quadra, bracket base is positioned at four jiaos of quadra, is provided with horizontal concrete chute in the bottom of bracket base, and top is provided with vertical chute.Therefore, the semi girder that afterbody is equipped with boring tower can move forward and backward by vertical chute, and the movable support bracket of carrying boring tower and semi girder can be made move left and right by horizontal concrete chute.As seen have only between movable support bracket and platform and the semi girder to have relative displacement, and the position between boring tower and the semi girder is changeless that the force-bearing situation that this has just improved semi girder has improved the supporting capacity of semi girder.
The beneficial effects of the utility model are: this oil drilling platform boring tower mobile device, owing to adopt by four bracket bases, two pallet stringers and two movable support brackets that the carriage crossbeam is formed, the bottom that is positioned at four jiaos bracket base is provided with the chute that makes movable support bracket do transverse movement, top is provided with the chute that semi girder is travelled longitudinally, and boring tower is the tail end that is fixed on semi girder.This movable support bracket can make the position that boring tower correctly is positioned at needs work easily, and simple in structure, reliable operation, especially improved the load situation of semi girder, improved the drilling duty of offshore boring island, increased drilling depth, drilling efficiency and economy are further enhanced.
