(2) background technique
The Shengli Oil Field neritic area is because the particularity of sea situation and ocean current and artificial structure's influence make submarine pipeline unsettled section phenomenon occur near platform.Exposed unsettled section of submarine pipeline because of swung back and forth by ocean current, alluvion.When its local location surpassed fatigue limit, pipeline just might rupture, and oil accident takes place, and caused great economic loss and seawater pollution.This problem must solve as early as possible.Patent documentation and relevant scientific and technological data are not found the patented technology and the effective measures that address this problem by retrieval.
(3) summary of the invention
The purpose of this utility model just is to provide a kind of submarine pipeline fixing device, and exposed unsettled section pressure of submarine pipeline is fixed on the sea bed, prevents to rupture because of swinging repeatedly, guarantees the operation of submarine pipeline long-term safety.
Above-mentioned purpose is realized by following technical proposals:
The submarine pipeline fixing device is made up of U-shaped clamp, cantilever beams, fixing stake pipe, cutting ferrule body, locking nut, revolution support, adjustment plate, attachment pegs, jack and adjustment spanner thereof, supporting baseplate.The U-shaped clamp clamps exposed unsettled section of submarine pipeline, and the clamp two ends are fixed to above the cantilever beams with screw bolt and nut.Cantilever beams is welded on the cutting ferrule body.The cutting ferrule body is enclosed within the fixing stake tube outside, and is locked on the pipe with locking nut.Revolution is supported and also is enclosed within the fixing stake tube outside, and places cutting ferrule body bottom, and the outer shroud that revolution is supported is integrally welded by the lower end of pin and cutting ferrule body.Adjust plate and place fixing stake pipe inside, and support following in revolution.Jack also places fixing stake pipe inside, and is adjusting plate bottom.The upper end of jack is connected with the adjustment plate by attachment pegs.Supporting baseplate also places fixing stake pipe inside, and plays a supportive role in jack bottom.
Cantilever beams in the above-mentioned submarine pipeline fixing device is formed by left beam slab, right beam slab and last beam slab welding assembly.An oblique angle is respectively cut away in the bottom of its left beam slab and right beam slab, to alleviate deadweight.Upper surface of beam slab is processed into rough surface on it, skids under the U-shaped clamp preventing.
Revolution in the above-mentioned submarine pipeline fixing device is supported for toroidal, is made up of bottom plate, bearing and attachment bolt.The outer shroud of bearing is integrally welded by pin and cutting ferrule body lower end.The interior ring of bearing welds together by pin and bottom plate.Bottom plate welds together with the adjustment plate.After submarine pipeline is fixing, cutting ferrule body, revolution support and bottom plate etc. are connected into one with attachment bolt.
The submarine pipeline fixing device that it becomes according to the technique scheme manufacturing, can be fixed to exposed unsettled section of submarine pipeline on the sea bed firmly, no longer swing back and forth because of ocean current, sea beat, also just the pipeline fracture accident can not take place, its economic benefit, environmental benefit and social benefit are conspicuous.
(4) description of drawings
Accompanying drawing 1 is an overall structure plan view of the present utility model.
Accompanying drawing 2 is that the A of Fig. 1 is to left view.
Accompanying drawing 3 is that the B of Fig. 1 is to plan view.
In the accompanying drawing, the 1st, U-shaped clamp, the 2nd, cantilever beams, the 3rd, the attachment bolt that revolution is supported, the 4th, fixing stake pipe, the 5th, the cutting ferrule body, the 6th, locking nut, the 7th, revolution is supported, and the 8th, adjust plate, the 9th, attachment pegs, the 10th, jack, the 11st, jack is adjusted spanner, the 12nd, supporting baseplate.
(5) embodiment
As shown in drawings, this installs by U-shaped clamp 1, cantilever beams 2, and attachment bolt 3, fixing stake pipe 4, cutting ferrule body 5, locking nut 6, revolution supports 7, adjusts plate 8, attachment pegs 9, spanner 11 adjusted by jack 10, jack and supporting baseplate 12 is formed.U type clamp 1 clamps exposed unsettled section of submarine pipeline, and the clamp two ends are fixed to above the cantilever beams 2 with screw bolt and nut.Cantilever beams 2 is welded on the outer surface of cutting ferrule body 5.Cutting ferrule body 5 is enclosed within fixing stake pipe 4 outsides, and is locked on the fixing stake pipe 4 with locking nut 6.Revolution is supported 7 and also is enclosed within fixing stake pipe 4 outsides, and places cutting ferrule body 5 bottoms, and the outer shroud of revolution support 7 is integrally welded by the lower end of pin and cutting ferrule body 5.Adjust plate 8 and place fixing stake pipe 4 inside, and support 7 bottom in revolution.Jack 10 also places fixing stake pipe 4 inside, and in the bottom that adjusts plate 8.The upper end of jack 10 is connected with adjustment plate 8 by attachment pegs 9.Supporting baseplate 12 also places fixing stake pipe 4 inside, and plays a supportive role in the bottom of jack 10.With attachment bolt 3 cutting ferrule body 5, revolution support 7 and adjustment plate 8 etc. are connected into one.
The on-site construction operations process of this device is: earlier this device and fixing stake pipe 4 are assembled into an integral installation shipping to the job site.Be placed in the centralizing bracket again, together sling by the crane barge on the workboat, make fixing stake pipe 4 keep plumbness, its lower end is inserted into the exact position of sea bed, and notices that its cantilever beams 2 is not directly over submarine pipeline.Under the cooperation of centralizing bracket, pile driver is squeezed into fixing stake pipe 4 under the sea bed together with other parts then, until overhang 2 near sea bed and a little less than submarine pipeline.Loosen locking nut 6, rotate revolution and support 7, cantilever beams 2 is forwarded to below the submarine pipeline.Operation jack 10 upwards promotes adjustment plate 8, and plate 8 upwards promotes revolution support 7 and cantilever beams 2 is moved upwards up to appropriate position together by adjusting.With U-shaped clamp 1 submarine pipeline is fixed on the overhang horizontal stroke 2 for unsettled section.Fixing stake pipe 4 and the submarine pipeline distance between the two can be by overhang horizontal stroke 2 the slotted hole of last beam slab finely tune, adjusting finishes promptly tightens the screw bolt and nut at U-shaped clamp 1 two ends.Underwater operation will be assisted to carry out by the diver.
