Description
Technical field
The present invention relates to a kind of movable bracket of cantilever beam on platform of drilling for oil, it belongs to the oil drilling platform apparatus field.
Background technology
Jack-up drilling unit is the basic drilling well facility that carries out the marine oil field drilling operation, is made up of platform main body, liftable spud leg and the cantilever beam that can do to move forward and backward on platform deck.The cantilever beam tail end is equipped with boring tower, and when cantilever beam moves when stretching out outside the drilling platform stern backward, its boring tower is in outside the aft end, and rig is in control position, can carry out drilling operation.When cantilever beam 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-drilling 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 jack-up drilling unit boring tower position is now: longitudinally establish intermeshing slideway with the cantilever beam lower surface on platform deck, with the cylinder pushes cantilever beam, whole cantilever beam 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 the side travel of boring tower along laterally establishing intermeshing slideway on the cantilever beam tail end.The shortcoming of this move mode is: travel mechanism divides two-layer up and down, complex structure; When boring tower when side travel makes boring tower position deviation cantilever beam longitudinal centerline because cantilever beam bears eccentric load, its load-carrying capacity descends, and the boring tower top hook load of sign drilling capacity is reduced, drilling depth reduces.
Summary of the invention
For the boring tower that overcomes existing oil drilling platform move existence between topic, the invention provides a kind of movable bracket of cantilever beam on platform of drilling for oil, this movable bracket of cantilever beam should simple in structure, reliable operation; Under any circumstance, cantilever beam can not bear eccentric load, thereby improves the flat-bed drilling capacity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of movable bracket of cantilever beam on platform of drilling for oil, and it mainly comprises drilling platform, boring tower and a cantilever beam, cantilever beam one end that boring tower is housed can reach the outside of drilling platform.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 drilling platform 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 bilge logss that are positioned at the cantilever beam 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 first otic placode and the first ratchet bearing, is provided with ratchet holes on the base plate of carriage bilge logs, and ratchet holes matches with first ratchet.Horizontal mobile device is fixed on the carriage crossbeam through second otic placode and the second ratchet bearing, is provided with ratchet holes on the panel of carriage glide path, and ratchet holes matches with second 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 cantilever beam 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 cantilever beam can be made sway by horizontal concrete chute.As seen have only between movable support bracket and platform and the cantilever beam to have relative displacement, and the position between boring tower and the cantilever beam is changeless that the force-bearing situation that this has just improved cantilever beam has improved the load-carrying capacity of cantilever beam.
The invention has the beneficial effects as follows: this movable bracket of cantilever beam on platform of drilling for oil, 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 make cross motion, top is provided with the chute that cantilever beam is travelled longitudinally, and boring tower is the tail end that is fixed on cantilever beam.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 cantilever beam, improved the drilling capacity of drilling platform, increased drilling depth, drilling efficiency and economy are further enhanced.
