Description
Technical field
This utility model relates to a kind of spud leg, particularly relates to the truss framed leg of a kind of jack-up unit.
Background technology
Jack-up unit is marine a kind of movably marine structure, is mainly made up of main platform body, spud leg, elevating mechanism, retaining mechanism and living facilities and equipment.Spud leg is the critical component of jack-up unit, and the total weight of rear support platform is mainly risen in effect at platform, and load is transferred to seabed, and its design quality is directly connected to the safety of platform.The form of spud leg can be divided into case type and truss-like two class, and case type can be divided into pinion and-rack and bolt-type.The major defect of case type spud leg is that steel construction utilization rate is low, compares with truss framed leg, in the case of equal bearing capacity, need more steel, and be only applicable to the shallow water area of less than 60 meters, deeper the most then needs increases spud leg size, causing bigger seaway load, construction weight also increases.The major advantage of case type spud leg is, spud leg comparison is simple, and especially latch cellular type spud leg is without welding tooth bar, reduces difficulty of construction and the manufacturing cost of spud leg.Truss framed leg is made up of string pipe and strut, and conventional spud leg main chord tube is made up of semi-circular plate and tooth bar.Truss framed leg major defect is to make to require height, and especially welding and the installation difficulty of tooth bar is bigger.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide the truss framed leg of a kind of jack-up unit, that eliminates welding and the self-locking locking structure of tooth bar.
For achieving the above object, this utility model provides the truss framed leg of a kind of jack-up unit, it includes the string pipe of circular pipe type, down tube, interior horizontal brace, and latch, wherein, this down tube is that X-type is arranged between this string pipe, this interior horizontal brace is arranged between this down tube, in same level, this string pipe each is provided with two pin-and-holes, the version of this pin-and-hole is oval hole, stagger in the junction of the position of this pin-and-hole and this string pipe and this down tube and one intercept height of this string pipe is the integral multiple of this pin-and-hole pitch of holes, this latch is provided with inserting paragraph and supporting section, the size of this inserting paragraph is corresponding with the size of this pin-and-hole.
The lateral dimension in this inserting paragraph cross section is less than vertical dimension.
The truss framed leg of this utility model jack-up unit, without welding tooth bar, reduces difficulty of construction and the manufacturing cost of spud leg, improves the economy of product, and coordinates, by pin-and-hole and latch, the effect of locking played, it is not necessary to additionally increase independent fastening system.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to be fully understood from the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the truss framed leg of this utility model jack-up unit.
Fig. 2 is the side view of this utility model latch.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further elaborated.
As shown in Figures 1 and 2, this utility model provides the truss framed leg of a kind of jack-up unit, and it includes string pipe 1, down tube 2, interior horizontal brace 3, and latch 4, wherein, this string pipe 1 for circular pipe type and is provided with pin-and-hole 11, this down tube 2 is arranged in X-type between this string pipe 1, and this interior horizontal brace 3 is arranged between this down tube 2, with firm overall structure, this latch 4 is provided with inserting paragraph 41 and supporting section 42, and the size of this inserting paragraph 41 is corresponding with the size of this pin-and-hole 11.
This string pipe 1 is spliced by two halves plectane or directly selects seamless steel pipe, relative rack type string pipe, has at least saved twice weld seam, string pipe for unit intercept, its welding capacity, wlding, artificial, man-hour etc., all reduce 50%, improve the economy of product on the whole.
In same level, this string pipe 1 each is provided with two these pin-and-holes 11, the version of this pin-and-hole 11 is oval hole, the vertical straightway leaving 50mm, with facilitate this inserting paragraph 41 into and out, reduce making, location tolerance requirement, also reduce the making of corollary equipment, location tolerance requirement equally.And, for avoiding the junction at this string pipe 1 and this down tube 2 to occur that stress is concentrated, stagger in the junction of the position of this pin-and-hole 11 and this string pipe 1 and this down tube 2, and 1 one intercept height of this string pipe are the integral multiples of this pin-and-hole 11 pitch of holes.
In order to further facilitate respectively pruning a part, such as 5mm into and out, this inserting paragraph about 41 of this inserting paragraph 41, make the lateral dimension in this inserting paragraph 41 cross section less than vertical dimension.Meanwhile, changes of section for avoiding this latch 4 is excessive causes hard spot, and this inserting paragraph 41 and the join domain of this supporting section 42 use fillet excessive.This supporting section 42 is arranged in the mobile slide block of jack-up unit movable slider unit, when platform needs to rise or fall, this inserting paragraph 41 from this pin-and-hole 11 from extracting, when platform is fixed, this inserting paragraph 41 is inserted in this pin-and-hole 11, now, this latch 4 plays the mobile slide block of locking and the effect of carrying platform part weight.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should be in the protection domain being defined in the patent claims.
