Description
Technical field
The utility model relates to a kind of spacer block device, particularly about a kind of spacer block device that is applicable to the tower standpipe in deep-sea.
Background technology
As one of the most key technology of deep water hydrocarbon exploitation, the deep water standpipe is the unique structure that connects between hydrocarbon sub-marine field and the marine float, also is one of important foundation facility of deep water hydrocarbon exploitation.As a kind of standpipe form that is widely used in the deep-sea, the vertical standpipe of Free Station is with the vertical body part of rigid riser as standpipe, provide required tension force by its top buoyancy tube, make in its water of being kept upright, and the jumper connection flexible pipe by the top couples together the floating structure on itself and the water surface, and the top is by the outlet of U type and expand and curvedly is connected with submerged pipeline.
On form of structure, the vertical standpipe of Free Station comprises tower standpipe and single hybrid standpipe.Both differences are tower standpipe with several standpipe boundlings together, and comprising production, water filling, gaslift, and cable etc., assembling on the bank is built in together then, drag it to the position of offshore oilfield by the towage mode, install.The rigid riser part of tower standpipe, based on a division center pipe, link to each other with the top buoyancy tube with the seabed, bearing axial pulling force, other productions, water filling, gaslift, and cable etc. adhere to standpipe and be attached to around the division center pipe by spacer block, with guarantee its installation and on the throne after requirement.
In the manufacturing process of tower standpipe, it is a crucial process that central tube and each attached tube that processes installed and fixed together, all realizes this installation process by spacer block at present.In the tower standpipe that has come into operation at present, all according to the central tube of tower standpipe and the size and the position of each attached tube, the form that spacer block is designed to fix, be similar to and opened a lot of holes on the steel plate, time processing moulding during production, in use, central tube and each attached tube are passed from corresponding hole, thereby reach the purpose of fixing each pipeline.
Owing to adopted the mounting means that passes through spacer block, need central tube and each attached tube etc. to pass successively, therefore when passing through, had relatively high expectations in place, construction technology etc., be unfavorable for operation, and the duration is longer, and manufacturing tolerance requires very high.Because transmission is different liquid in the attached tube, therefore also each is different for the expansion of each attached tube, contraction change scope, and in order to prevent slippage, spacer block and central tube, attached tube etc. often weld together, slippage not only bad for single pipeline changes like this, thereby makes pipeline produce local buckling, the concentrated phenomenon of stress, also can be owing to expansions different between the different pipelines, contraction change, cause standpipe totally to produce distortion, unstable phenomenon, thereby structural deterioration occurs.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides and a kind ofly can satisfy tower standpipe central tube in deep-sea and the requirement of attached tube beam function, the spacer block device of being convenient to production and processing again and installing and using.
For achieving the above object, the utility model is taked following technical scheme: a kind of spacer block device that is applicable to the tower standpipe in deep-sea, it is characterized in that: it is made of with the guiding tube consistent with the attached tube number at least two gripper shoes that be arranged in parallel, the central tube of tower standpipe passes from described gripper shoe, and attached tube is passed from described guiding tube; The middle part of described gripper shoe offers the diameter centre bore identical with the central tube external diameter, and is axle with certain diameter of described centre bore, and described gripper shoe is divided into two parts, and reserves the installation site of described guiding tube on the described gripper shoe of every half block; Described guiding tube internal diameter is identical with the attached tube external diameter, and is two parts that axle is divided into symmetry with the diameter; The two ends of per half described guiding tube are provided with installing plate, and each evenly is furnished with 3～4 bolts on the described installing plate of every side; Half guiding tube in each described guiding tube is welded on the installation site of guiding tube on the described gripper shoe, and the line in the centre bore center of circle is perpendicular on the diameter of half described guiding tube incision and the described guiding tube center of circle and the gripper shoe.
Described centre bore is 50mm～100mm apart from the beeline of described support plate edge, and the thickness of described gripper shoe is 25mm～30mm.
Add rubber pad in described guiding tube, this moment, described guiding tube internal diameter was attached tube external diameter and rubber pad thickness sum, and the wall thickness of described guiding tube is 15mm～20mm, and described guiding tube axial length is 500mm～700mm.
The utility model is owing to take above technical scheme, it has the following advantages: 1, gripper shoe of the present utility model is designed to left and right sides two parts, gripper shoe is installed around the central tube butt joint during installation, and be welded on the central tube, need not central tube and from spacer block, pass, thereby reduced the technological requirement of installation.2, the utility model at first is arranged in corresponding guiding tube reserved location on the spacer block when attached tube is installed, and uses outer buckle, is installed together by bolt and spacer block, thereby has reduced difficulty of construction, has shortened the duration, and the place is not had specific (special) requirements.3, gripper shoe of the present utility model and central tube weld together, other adhere to pipeline and are installed together by the guiding tube on bolt and the spacer block, the axially-movable that allows attached tube to cause owing to expansion, contraction etc., thus avoided because the structural deterioration that the local buckling of single pipeline causes.4, different attached tube and spacer blocks all are to pass through guiding tube, the use bolt is installed together, therefore all attached tube can axially move, and it is separate, noiseless, thus avoided because structural deterioration phenomenons such as the standpipe structural strain's that different change in displacement causes between the different pipelines, unstabilitys.5, structural deteriorations such as crackle occur when one or more attached tube, when maybe needing to be replaced with the attached tube of other functions, can pass through the underwater robot execute-in-place, and need not unload whole tower standpipe, be dragged to construction on the bank again, made things convenient for replacing, the installation process of attached tube, shortened the duration.
