Abstract
A self-elevating marine drilling platform mainly solves the problems that a lifting mode of an existing drilling platform is low in work efficiency, and a deck is prone to being damaged by impact of high-altitude falling objects. The self-elevating marine drilling platform is characterized in that the two sides of a spud leg (3) are symmetrically and fixedly provided with racks (4), a platform body (2) is fixedly provided with gears (5), and the racks (4) are matched with the gears (5); the upper portion of the platform body (2) is connected with multiple trough-type supporting frames (8) arranged side by side through bolts (12), cushion plates (9) are disposed between the trough-type supporting frames (8) and the platform body (2), the longitudinal section of each trough-type supporting frame (8) is of a U shape, slabs (10) are welded to the upper portions of the trough-type supporting frames (8) in a one-to-one correspondence mode, and a deck (7) is connected with the upper portions of the slabs (10). The self-elevating marine drilling platform has the advantages of being convenient to ascend and descend and high in work efficiency, and the deck is resistant to impact and is not prone to being damaged.
Description
Technical field
The utility model belongs to Offshore Engineering technical field, specifically a kind of self-lifting type marine drilling platform.
Background technology
At present, what domestic and international existing well drilling of shallow sea platform generally adopted is hydraulic lifting mode and the drilling well of well head slot type, and inefficiency, has increased operating cost, is not suitable for shallow-water oilfield operation.Simultaneously; current offshore boring island is all generally that deck is directly connected with main platform body; although this structure is easily manufactured; but shock resistance is poor; while impacting deck when there is falling object from high altitude in the course of the work, usually can cause damage to deck, when serious, even can damage platform; and deck is keeped in repair inconvenient after damaging, affect the progress of operation on the sea.
Summary of the invention
For the problem that overcomes the up-down mode inefficiency of existing offshore boring island, impact that deck is vulnerable to falling object from high altitude and damage, the utility model provides a kind of self-lifting type marine drilling platform, this self-lifting type marine drilling platform has the advantages that lifting is convenient, operating efficiency is high, and deck shock resistance, not fragile.
The technical solution of the utility model is: a kind of self-lifting type marine drilling platform, comprise spud leg, main platform body, and described spud leg bilateral symmetry is fixed with tooth bar, is fixed with gear in main platform body, and described rack and pinion matches; Described main platform body top is bolted several grooved bracing frames arranged side by side, and be equipped with backing plate between grooved bracing frame and main platform body, the vertical section of described grooved bracing frame is U-shaped, grooved bracing frame top is welded with flat board, and the corresponding grooved bracing frame of one flat plate, dull and stereotyped top is connected with deck.
Described gear is 2 that are arranged above and below.
Described dull and stereotyped soffit is connected with some reinforcing ribs.
The utlity model has following beneficial effect: owing to taking such scheme, there is tooth bar described spud leg both sides, and tooth bar coordinates with the gear being placed in main platform body, after spud leg is fixing, gear rotates along gear rack elevating under the control of motor, thereby drives main platform body lifting.This up-down mode efficiency is high, flexible movements, and lifting is convenient, is especially applicable to shallow-water oilfield oil drilling operation.Meanwhile, main platform body upper surface has backing plate, and backing plate can adopt wooden or composite material, has so certain elasticity, can play certain cushioning effect; Main platform body top is connected with grooved bracing frame, and grooved bracing frame, due to inner hollow, when having falling object from high altitude, plays again certain cushioning effect; And each grooved bracing frame top is fixing one flat plate respectively, this structure, makes it on deck and during dull and stereotyped damage, can among a small circle, change, keep in repair, and can not affect operation on the sea.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at I place in Fig. 1.
1-shoe in figure, 2-main platform body, 3-spud leg, 4-tooth bar, 5-gear, 6-motor, 7-deck, 8-grooved bracing frame, 9-backing plate, 10-is dull and stereotyped, 11-reinforcing rib, 12-bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of self-lifting type marine drilling platform, comprises spud leg 3, main platform body 2, and spud leg 3 bottoms are connected with shoe 1, and during operation, main platform body 2 is fixed on seabed by shoe 1, and during towage, shoe 1 is completely retracted in main platform body 2.Described spud leg 3 bilateral symmetry are fixed with tooth bar 4, are fixed with gear 5 in main platform body 2, and described tooth bar 4 matches with gear 5, and the gear 5 of each tooth bar 4 correspondence is 2 that are arranged above and below.When platform towage arrives behind operating area, first spud leg 3 is dropped to seabed, shoe 1 is fixed on sea bed, then starter receiver is controlled motor 6, and lifting platform, can start operation.Described main platform body 2 tops are connected with several grooved bracing frames 8 arranged side by side by bolt 12, and be equipped with backing plate 9 between grooved bracing frame 8 and main platform body 2, backing plate 9 can be plank, also can be other composite material, there is certain elasticity, when having falling object from high altitude, can play certain cushioning effect.The vertical section of described grooved bracing frame 8 is U-shaped, grooved bracing frame 8 tops are welded with dull and stereotyped 10, the soffit of described flat board 10 is connected with some reinforcing ribs 11, and the corresponding grooved bracing frame 8 of one flat plate 10, the edge joint weld of every flat board 10 is connected on the U-shaped edge of grooved bracing frame 8, and dull and stereotyped 10 tops are connected with deck 7.When deck 7 and dull and stereotyped 10 is damaged by falling object from high altitude, can only change the one flat plate 10 damaging like this, easy to maintenance.
This self-lifting type marine drilling platform, up-down mode is flexibly, convenient, efficiency is high, is applicable to shallow sea operation; And because the cushioning effect of platform makes deck be difficult for being damaged by falling object from high altitude, meanwhile, just in case deck convenient maintenance and replacement after damage.
