Abstract
The utility model relates to a fixing device of high-pressure riser pipes in oilfields, in particular to a flexible U-shaped clamp for high-pressure riser pipes. The technical scheme includes that the flexible U-shaped clamp comprises two screw rods and a bend, wherein the bend utilizes a steel cable, the screw rods are of telescopic structure, and the steel cable is fixedly connected to the tail ends of the two screw rods through lock plugs. The flexible U-shaped clamp has the advantages of realizing convenient installation because requirements upon mounting positions of all parts are reduced, and reducing local friction because the steel cable and a damping rubber block can tightly cling to a high-pressure riser pipe.
Description
One, technical field:
The utility model relates to a kind of oil field high pressure vertical tube fixing device, the flexible U type of particularly a kind of high pressure vertical tube card.
Two, background technique:
In the work progress of installing, using at high pressure vertical tube, " U " type card is high pressure vertical tube to be fixed on one of main fixed component on the derrick.In the past, in installation process, because " U " type card is the integral rigidity parts, when passing vibration damping blob of viscose and derrick angle steel, fixed connecting plate to mounting hole, operation is effort, time-consuming relatively; Owing to be in high-lift operation, the higher work of intensity has also increased potential safety hazard simultaneously.In use, rigid element directly contacts with high pressure vertical tube, because the vibration of drilling fluid fluid can cause local friction, has shortened the working life of bolt and standpipe.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of easy to operate, the flexible U type of high pressure vertical tube card of reducing handling safety hidden danger is provided.
Its technological scheme is: mainly be made up of two screw rods and bend pipe, described bend pipe adopts wire rope, and screw rod is a shrinking structure, and described wire rope is fixedly connected on the end of two screw rods by lock core.
The end of above-mentioned screw rod is provided with cavity, inserts the wire rope of lock core and fills in the cavity of screw rod end, and the extruding of cavity outer wall is fixing, and outer wall produces plastic deformation, and wire rope produces resiliently deformable, fixedly secures wire rope.
Above-mentioned flexibility " U " type card substitutes wire rope with original " U " type card " U " type position, and wire rope and screw rod end adopt the hydraulic pressure compacting to reach working strength; In the as installed using process, should be used special-purpose vibration damping blob of viscose, just can use to reach the optimum state.
The beneficial effects of the utility model are: reduced status requirement to each assembly, thus easy for installation; Wire rope and vibration damping blob of viscose can be fitted closely with high pressure vertical tube, have reduced local friction.
Four, description of drawings:
Accompanying drawing 1 is a scheme of installation of the present utility model;
Accompanying drawing 2 is connection diagrams of screw rod of the present utility model and wire rope;
Among the last figure: U type card 1, damping blob of viscose 2, connecting plate 3, derrick angle steel 4, drilling fluid 5, high pressure vertical tube 6, wire rope 7, lock core 8, outer wall 9, screw rod 10.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
Its technological scheme is: mainly be made up of two screw rods and bend pipe, described bend pipe adopts wire rope 7, and screw rod 10 is a shrinking structure, and described wire rope 7 is fixedly connected on the end of two screw rods 10 by lock core 8; The end of screw rod 10 is provided with cavity, inserts the wire rope 7 of lock core 8 and fills in the cavity of screw rod end, and 9 extruding of cavity outer wall are fixing, and outer wall 9 produces plastic deformation, makes wire rope produce resiliently deformable, thereby firmly blocks wire rope.
During use, with reference to accompanying drawing 1, high pressure vertical tube 6 adopts the means of fixation of the underlay of hanging oneself, and drilling fluid 5 is arranged in the high pressure vertical tube, and its weight is mainly in base and derrick main body; U type card 1 is fixed on the derrick angle steel 4 by connecting plate 3, is provided with damping blob of viscose 2 between two screw rods of U type card,
U type card 1 suffered power has because derrick vibration, the mud tube that the derrick lift heavy causes promotes weight change, the vibration of drilling fluid fluid that descends and cause, generations such as wind environment factor; In above various factors, the derrick vibration force is its power that mainly is subjected to.
Derrick is in the process of vibration, and derrick and U type cassette tape dynamic high-pressure standpipe vibrate to all directions.
The hydraulic pressure compact technique is adopted in flexible " U " type card wire rope and screw rod end, makes the cavity outer wall produce plastic deformation, and wire rope produces resiliently deformable; Wire rope is clamp-oned in not modified screw cavity inside, makes the end reach usage requirement.The screw strength height because wire rope material compressive strength rate is untreated can not squeeze bad wire rope.Other locks pipe the structure that prevents that wire rope from reversing.
Claims (2)
1, the flexible U type of a kind of high pressure vertical tube card, mainly form by two screw rods and bend pipe, it is characterized in that: described bend pipe adopts wire rope (7), and screw rod (10) is a shrinking structure, and described wire rope (7) is fixedly connected on the end of two screw rods (10) by lock core (8).
2, the flexible U type of high pressure vertical tube according to claim 1 card, it is characterized in that: the end of described screw rod (10) is provided with cavity, inserting the wire rope (7) of lock core (8) fills in the cavity of screw rod end, the extruding of cavity outer wall is fixing, outer wall produces plastic deformation, make wire rope produce resiliently deformable, fixedly secure wire rope.
