Description
One, technical field:
The utility model relates to a kind of seawater column, particularly relates to the novel seawater column of a kind of self-lifting type marine drilling platform.
Two, background technology:
Drilling well, oil production platform and formation testing job platform generally all have seawater column.What jack up drilling well, oil production platform and formation testing job platform were adopted generally is the liftable seawater column.Its radical function is, when jack-up platform displacement and platform lift away from water surface diverse location, because the relative water surface site of diving pump changes in the seawater column, make that diving pump can not be normally or fine use, so can be by seawater column jacking system adjusting seawater column position.The mounting means that seawater column is traditional is on main deck, because will resist very big sea beat load, what the body of the tower structure design was made is big and heavy, and therefore the jacking system of seawater column also needs bigger hoisting capacity.Under platform air gaps service conditions, the body of the tower height that extends merely, under the wave loading, the body of the tower structure often can not satisfy requirement of strength.Another kind depends on the seawater column of platform leg structure, though the body of the tower structure has intensity to guarantee under platform air gaps service condition, but rely on the lifting platform system during because of knee-action, the latch that operates is repeatedly changed hands, simultaneously because when differing heights, need segmentation to connect aqueduct, so the single job elapsed time is long, also bother very much.
Three, utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, compact conformation, transmitting ratio is big, load-carrying capacity is high, easy installation and removal, the safe and reliable novel seawater column of self-lifting type marine drilling platform.
The technical solution of the utility model is:
The novel seawater column of a kind of self-lifting type marine drilling platform, comprise engine, speed reduction gearing, lifter wheel mechanism, seawater column body of the tower, described seawater column body of the tower contains pillar, in the described pillar aqueduct is installed, described aqueduct lower end is equipped with diving pump, and its upper end is connected by the seawater pipeline standpipe on the deck of flexible pipe and self-elevating ocean platform hull; Described pillar outer wall is provided with tooth bar and positioning guide plate, and described positioning guide plate is arranged in the guide groove plate, can move up and down along guide groove plate, and described guide groove plate is fixed on the footing truss string pipe of described self-elevating ocean platform hull; The drive pinion engagement of described tooth bar and described lifter wheel mechanism, the transmission big gear wheel of described lifter wheel mechanism connects with the output shaft of described speed reduction gearing, the input shaft of described speed reduction gearing connects with the output shaft of described engine, and described lifter wheel mechanism, speed reduction gearing and engine are installed on the deck of described self-elevating ocean platform hull.
Be provided with the catch gear of locking rack in the described lifter wheel mechanism.
Described seawater column body of the tower top is provided with bench board, is convenient to change aqueduct and diving pump.
Described guide groove plate is fixed on the footing string pipe of described self-elevating ocean platform by clip.
Described aqueduct top is provided with elbow, and described elbow is connected with seawater pipeline standpipe on the self-elevating ocean platform deck by flexible pipe.
Described engine is a motor, and described speed reduction gearing is few tooth difference reductor.
The beneficial effects of the utility model are:
1, the utility model seawater column body of the tower is installed and is depended on the platform leg, and it is resisted, and the wave ability is strong also can to realize air gaps work.
2, the utility model simple and light, can be voluntarily lifting, diving pump long working life and can conveniently change continuously.
3, the utility model supporting construction is simple and reliable, and the seawater column locking is convenient, reliable, has good economic benefit after the popularization.
Four, description of drawings:
