The auxiliary line bracket has the advantages of compact structure, small occupation space, light weight and capability of effectively reducing stress concentration and inhibiting vibration of the auxiliary line.
Description
Technical field
The utility model belongs to sea oil drilling and production equipment technology field, relates to a kind of auxiliary line support of Offshore Drilling Riser.
Background technology
Drilling water-separation pipe has insulating sea water, returns mud, supports the functions such as auxiliary line and guiding drilling tool as marine drilling platform (ship) and the crucial connection device between the blowout preventer set under water.Drilling water-separation pipe auxiliary line support is installed on the marine riser body, plays fixing and supports auxiliary line, reduces the effects such as the vibration of auxiliary line and fatigue failure.
Existing drilling water-separation pipe auxiliary line fixed support generally adopts steel split ring type structure, it is outside by bolt the split ring type structure to be fixed on the marine riser supervisor, its ring-like external cylindrical surface of this fixed support is welded with the auxiliary line fixed bearing, mainly has the deficiency of two aspects: the one, and the fixed bearing volume is large so that the whole outer profile size of drilling water-separation pipe is larger; The 2nd, produce easily stress in fixed bearing and auxiliary line contact site and concentrate, for application life and the security feature of auxiliary line adverse effect is arranged.
Existing its contour structure size of marine riser support is bigger than normal, and weight is larger, and at auxiliary line and support junction fatigue failure occurs easily.
Summary of the invention
The purpose of this utility model provides a kind of auxiliary line support of Offshore Drilling Riser, has solved to exist size bigger than normal in the prior art, and weight is larger, and easy problem in auxiliary line and the generation fatigue failure of support junction.
The technical scheme that the utility model adopts is, a kind of auxiliary line support of Offshore Drilling Riser, comprise a plurality of clips, each clip adopts being looped around on the marine riser main pipe cylindrical of split-type structure concentric, the excircle of each clip is provided with corresponding auxiliary line half slot, and each auxiliary line half slot cylindrical one side correspondence is equipped with an other semicircular outer baffle block.
The auxiliary line support of Offshore Drilling Riser of the present utility model is further characterized in that:
The preferred 2-4 of described clip.
Be fastened on the marine riser main pipe cylindrical by clamp bolt and clip nut between the described adjacent clip, and be provided with the installation via hole according to auxiliary line position and size; Adopt block bolt, block nut to be connected between the outer baffle block on clip and its excircle.
The internal layer of described clip and outer baffle block is provided with metallic framework, and the skin of metallic framework is enclosed with one deck polymer material layer.
The beneficial effects of the utility model are,
1) this support clip is formed by metallic framework and the whole sulfuration of polymer material layer, and is simple and compact for structure, effectively alleviated the weight of support.The structure attribute that contains polymer material layer has stronger flexible buffer ability, and the establishment vibration also reduces the damage of external surface metal level.
2) this structure manufacture process is simple, saves raw material, does not need Site Welding, effectively reduces manufacturing cost and has alleviated labour intensity in manufacturing and the installation process.
3) outer baffle block adopts metallic framework and polymer material layer sulfuration to form, and what prevented effectively that block from may occur comes off and sliding phenomenon, has increased the reliability that is fixedly connected with.
4) all preservative treatments of the suitable marine environment of part employing.
Description of drawings
Fig. 1 is the three-dimensional structure schematic diagram of the utility model auxiliary line support;
Fig. 2 is the agent structure sectional view of the utility model auxiliary line support.
Among the figure, 1. clip, 2. outer baffle block, 3. block bolt, 4. block nut, 5. clamp bolt, 6. clip nut, 7. metallic framework, 8. polymer material layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, the auxiliary line supporting structure of Offshore Drilling Riser of the present utility model is, comprise a plurality of clips 1, (preferred 2-4), each clip 1 adopts being looped around on the marine riser main pipe cylindrical of split-type structure concentric, the excircle of each clip 1 is provided with corresponding auxiliary line half slot, and each auxiliary line half slot cylindrical one side correspondence is equipped with an other semicircular outer baffle block 2.
Be fastened on the marine riser main pipe cylindrical by clamp bolt 5 and clip nut 6 between the adjacent clip 1, and be provided with the installation via hole according to auxiliary line position and size; Adopt block bolt 3 between the outer baffle block 2 on clip 1 and its excircle, block nut 4 is connected and clamp the marine riser auxiliary line.
With reference to Fig. 2, the endothecium structure of clip 1 and outer baffle block 2 is metallic framework 7, the skin of metallic framework 7 is enclosed with one deck polymer material layer 8(polymer material layer 8 preferred anti-corrosion vulcanized rubbers), form by the integral body sulfuration, have effect of vibration lightweight and energy establishment auxiliary line, reduce the characteristics of fatigue failure.
In drilling water-separation pipe auxiliary line assembling process, first split-type clip 1 is fixed on the drilling water-separation pipe main body cylindrical with clamp bolt 5, clip nut 6 according to the aligned position of each auxiliary line successively, each auxiliary line is installed subsequently, by block bolt 3, block nut 4 outer baffle block 2 is installed on the clip 1 at last, to reach the purpose of fixing each auxiliary line.
Device of the present utility model, takes up room little, lightweight and can reduce effectively that stress is concentrated and suppress the auxiliary line vibration at compact conformation, has effectively suppressed fatigue failure.
