The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The oil standpipe expansion joint that the utility model is related, the position during its work as shown in Figure 1, its structure is as shown in Figure 2.Upper flange 1 is fixedlyed connected with inner core 3 by locking sleeve 2, the relative position of inner core 3 assurances and hull is constant, inner core 3 excircles are set with top and connect cylindrical shell 7, top connects cylindrical shell 7 and is connected with the urceolus 8 of expansion joint, inner core 3 stretches in the urceolus 8 simultaneously, and the relative position of urceolus 8 assurances and subsea wellheads is constant.In the time of in working order, upper flange 1 and two flange box cupling are thrown off, hull is along with wave drives inner core 3 beginnings fluctuation up and down, the urceolus 8 of expansion joint 13 then links to each other with subsea wellheads by riser joint, keep motionless, just produce relatively between inner core 3 and the urceolus 8 like this and slide, finally realized the flexible compensation function of expansion joint 13.
Hydraulic pressure Long-distance Control locking device described in the utility model, its work schematic diagram as shown in Figure 1, structure as shown in Figure 3, the circumference that is included in top connection cylindrical shell 7 is provided with 6 hydraulic locking apparatus 12,6 hydraulic locking apparatus 12 are connected with long-range hydraulic control device 11 by hydraulic pressure release pipeline 9, each hydraulic locking apparatus 12 comprises hydraulic locking cylinder 4, be provided with lock pin 5 and spring 6 in hydraulic locking cylinder 4 piston chamber, spring 6 is installed in the radial outer end of lock pin 5, guarantee to move to the axle center of top connecting cylinder body 7 automatically when lock pin 5 is not stressed, one end of piston chamber is connected with hydraulic pressure release pipeline 9, hydraulic pressure release pipeline 9 is with long-range hydraulic control device 11 UNICOMs and accept control, is used in the expansion joint, the locking of urceolus and release.During work, pressurize by 11 pairs of hydraulic locking cylinders of long-range hydraulic control device on the operation drill ship 4, drive lock pin 5 and move, compression contained spring 6 to axis direction withdrawal lock pin 5, is realized the release of expansion joint inner core 3 and urceolus 8; On the contrary, after hydraulic pressure release pipeline 9 passed through 4 pressure releases of hydraulic locking cylinder, compressed spring 6 resetted, and driving lock pin 5 moves outward and stretches out, and lock pin 5 inside end are inserted in the annular groove of top connection cylindrical shell 7, realized the locking of expansion joint inner core 3 and urceolus 8.
The operating mode of locking device described in the utility model is divided into following two kinds: expansion joint transportation or transfer reclaim the operating mode of standpipe, the operating mode that expansion joint realizes position compensation.Transportation, transfer when reclaiming standpipe, the inner core 3 of expansion joint 13, urceolus 8 need locking, hydraulic locking pipeline 9 does not have pressure at this moment, 6 lock pins 5 stretch out under the pressure of spring 6, in the annular groove on the locking sleeve 2 that insertion and inner core 3 link together, realize the inner core 3 of expansion joint 13, the locking purpose of urceolus 8; During work, when promptly realizing the position compensation function of expansion joint 13, need be with inner core 3, the fixedly connected release of urceolus 8, then 9 pairs of hydraulic locking cylinders of hydraulic pressure release pipeline, 4 pressurizations by linking to each other with long-range hydraulic control device 11 on the platform of sea, drive 6 lock pins, 5 compression springs 6, and withdrawal lock pin 5, the final expansion joint inner core 3 of realizing, the release action of urceolus 8, because 6 hydraulic locking cylinders are arranged in parallel, so release is rapid when using hydraulic pressure, synchronism was good when lock pin 5 was regained, while is owing to the reason of overall construction design, after the lock pin release, expansion joint realizes that each hydraulic locking cylinder need not pressurize between the position compensation functional period.
Each hydraulic locking apparatus 12 can be by the form of hydraulic pressure release pipeline 9 to the 4 pressurization releases of hydraulic locking cylinder, pressure release locking, also can be the form of pressurization locking, pressure release release.
Each hydraulic locking apparatus 12 can not be provided with spring 6, and adopt two hydraulic cavities structures, as shown in Figure 4, two hydraulic cavities are connected with long-range hydraulic control device 11 by hydraulic pressure release pipeline 9, hydraulic locking pipeline 10 respectively, the pressurization and the release of hydraulic locking cylinder 4 are carried out in work cooperation according to long-range hydraulic control device 11, realize release and locking operation.
Each hydraulic locking apparatus 12 is made of 6 hydraulic locking apparatus 12, or by 2,3,4 or a plurality ofly constitute, its composing quantity is by the decision of bearing capacity size;
Marine riser expansion joint of the present utility model hydraulic pressure Long-distance Control locking device, when advantage is that expansion joint realizes the operating mode of position compensation, can realize operated from a distance, do not need the workman below the drilling and producing platform moon pool, to carry out release of inside and outside tube and locking by hand, danger when so just having avoided the workman to operate also can be shortened the operating time simultaneously.
