Description
Technical field
The present invention relates to ocean engineering and shipbuilding technical field, particularly to the spud leg manufacture method of a kind of meter of font stay tube.
Background technology
In Marine oil and gas resource development process, self-elevating drilling platform is mainly used in Oil/gas Well of prying into, can also be used for playing producing well, workover treatment, also can be as the drilling and producing platform in producing in early days, the realization of these major functions, depends on the application of its particular component such as spud leg, jacking system, locking device and cantilever beam etc..
Being mounted with drilling machinery, power, equipment, accommodation and some liftable spud legs on self-elevating drilling platform, during drilling well, the shoe bottom spud leg at the end, and platform then lifts away from sea certain altitude along spud leg；During displacement, the water surface is down to by platform, and spud leg rises, and platform, just as barge, can be dragged it by tugboat and move on to new well location.Spud leg is the key position of self-elevating drilling platform, when self-elevating drilling platform implements operation when, need to then carry out the pitching pile of spud leg by elevating mechanism by above for platform raising to sea safe altitude, and supported whole platform by shoe.
Truss framed leg be self-elevating drilling platform be to build self-elevating drilling platform to build one of important step, general first carry out prefabricated by land, then, then transport to sea and assemble.
General, self-elevating drilling platform is in spud leg installation process, crane gear is required the highest, especially at harbour pile extension lower limb, 300 feet, 350 feet and 400 feet of platforms often to reach 120～the height of more than 160 meter, the somewhat expensive using large-scale crane crawler crane or sea to hang, causes the expenditure of construction of platform to increase severely.
At present, when domestic truss framed leg makes, domestic and international commonly used lateral plate makes and combines down tube mode in bulk to solve overlap joint problem, the requirement of implementing of this scheme completes, at spud leg segmented volumetric formative stage, the work that down tube is in bulk, but molding moulding bed uses the cycle longer, and welding quality and welding deformation are difficult to control to, amount of high-altitude operation is more.
Especially, truss-like " rice " font bracing tube structure is used for 400 chi drilling platform legs, and stay tube joint is mostly joint form, the most how to optimize the assembling of all kinds of stay tubes in spud leg building course and be always an international difficult problem with welding.
Therefore, it is badly in need of research and development one and can shorten spud leg segmented volumetric molding cycle, it is ensured that the spud leg manufacture method of the rice font municipal administration of welding quality is imperative.Through checking relevant document, do not find technical scheme same or analogous with the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and shortens spud leg segmented volumetric molding cycle, in turn ensure that the spud leg manufacture method of the rice font stay tube of welding quality.
For solving above-mentioned technical problem, the technical scheme is that the spud leg manufacture method of a kind of meter of font stay tube, described spud leg stereo shaping includes down tube stage in bulk and lateral plate production phase, its innovative point is: the described down tube stage in bulk is that down tube in bulk and horizontal brace control are made a meter font stay tube assembly, the welding of inter-module is carried out in the lateral plate production phase, last stereo shaping, described rice font stay tube assembly is made up of the triatic stay of a vertical direction and two hounds of both sides.
Further, the manufacture method of described rice font stay tube concretely comprises the following steps:
(1) welding support prepares: described welding support is made up of some crisscross body of rod A, and it being provided with some for spacing and support the support seat of down tube and horizontal stay tube on support, the position of described support seat is the most corresponding at the two ends of down tube Yu horizontal stay tube；
(2) welding: be first placed on down tube in the support seat that support is corresponding by horizontal stay tube, making down tube and horizontal stay tube is the arrangement of rice font, then by two people welding simultaneously from both sides, down tube is welded on the both sides of horizontal stay tube；During welding, the weld seam that the down tube that freezes passes through mutually with horizontal stay tube, welding 3-4 road, then back gouging, polishing mother metal surface 2-3mm, take out carburized layer.
Further, in described step (2), the outer end of described each hound is all fixed with adjacent triatic stay by a pole, and this pole is made up of the anchor ear of a body of rod B and body of rod B two ends.
It is an advantage of the current invention that:
1. original high-altitude down tube operation in bulk is transformed into ground and carries out by the spud leg manufacture method of the present invention, on ground, down tube in bulk and horizontal brace control are made a meter font stay tube assembly, then at lateral plate production phase welding equipment rice font municipal administration assembly, avoid in high altitude bulk workload, optimize in spud leg building course the assembling of all kinds of stay tubes and weld, save the effect continuing on large-scale superelevation loop wheel machine expense, effectively reduce the difficulty installing spud leg, shorten spud leg segmented volumetric molding cycle, reduce production cost.
2. the rice font municipal administration assembly making method of the present invention is simple, utilizes special welding support, is placed on support with horizontal stay tube by down tube and welds, improves a meter make efficiency for font stay tube assembly, and welding quality.
3. during welding, the outer end of hound is locked with triatic stay by pole so that during welding, down tube locking fixing with horizontal stay tube, it is to avoid during welding, down tube offsets with horizontal stay tube, facilitates welding operation, improves welding quality and welding efficiency.
