Description
Technical field
The utility model relates to the tensioner fluid cylinder, particularly the anti-platform fastening devices of a kind of tensioner fluid cylinder.
Background technology
Along with the development of human marine cause, the marine drilling engineering is more and more used.The ocean engineering operation generally all will relate to well system, and wherein very important a kind of well system is exactly ocean floating type drilling platform.Ocean floating type drilling platform except waving, also will produce up and down heave movement all around under wave action.This motion with heave about the wave period will cause that drill string and riser system periodically move up and down.Riser system periodically moves up and down and will have a strong impact on drillng operation or so that wellhead assembly disengaging shaft bottom.Therefore in order to guarantee that unsteady offshore boring island normally creeps into, improve drilling efficiency, just must adopt heave compensation system, with the relative motion in minimizing drill string and riser system and seabed, and keep constant tensioning load.Usually the ocean floating type drilling platform heave compensation system mainly comprises drill string compensation and two aspects of riser system compensation.
The riser system compensation mainly is comprised of marine riser stretching device and marine riser stretcher.Stretching device overcomes up and down periodic heave compensation function of wave, the stability during with the work of maintenance riser system, and stretcher provides permanent tension force control to riser system.Stretching device and stretcher are used in conjunction with each other, and reach boats and ships purpose to the riser system heave compensation under the ocean operation environment.
Wherein, the tensioner fluid cylinder is the visual plant of marine riser heave compensation system, and its upper end is connected to the stretcher slide device, and the lower end is fixed by the stretcher chuck.This system is used at whole hull up and down during heave movement, and flexible to realize the compensation to the marine riser heave by oil cylinder avoids damaging marine riser.Because the deadweight of stretcher fluid cylinder is larger, length is longer, and is installed in narrow and small moon pool area, before fluid cylinder bottom chuck was installed, single oil cylinder was easy to and moon pool structural collision on every side at the effect lower swing of wind-force, damage oil cylinder, particularly or typhoon Lantus strong at wind-force waited.Be not specifically designed to the device of fixed tensioning device fluid cylinder in the prior art, use general cucurbit to add the easy devices such as suspender belt or rope be fixing and can't guarantee stability and the safety that fluid cylinder is fixing.
The utility model content
The technical problems to be solved in the utility model is in order to overcome in the prior art before stretcher fluid cylinder bottom chuck is installed, there is not to be specifically designed to the device of fixed tensioning device fluid cylinder, so that can swinging when wind-force is stronger, fluid cylinder bumps with moon pool structure on every side, damage oil cylinder, also can't guarantee the safety of fluid cylinder with some Simple fixing devices.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of tensioner fluid cylinder is prevented the platform fastening devices, and its characteristics are, comprising: a support and at least one for the fixing fixed part of fluid cylinder in the horizontal direction, this at least one fixed part is fixedly connected on this support.
Preferably, the shape of this at least one fixed part comprises one section circular arc at least, is used for matching with the circular periphery of fluid cylinder horizontal direction.Match by such shape, can be more stable fix fluid cylinder, and fluid cylinder is when rocking under wind effect, stressed more even on this fixed part.
Preferably, comprise on this support: a pedestal, two crossbeams and a plate, the two ends of these two crossbeams are fixedly connected with this pedestal with this junction plate respectively.Two crossbeams that arrange in the technical program are except playing the effect that is fixedly connected with this junction plate and this pedestal, and the anti-platform fastening devices of this tensioner fluid cylinder can be applicable to from the fluid cylinder of offshore boring island away from.
Preferably, this at least one fixed part is U-bolt, and corresponding to each U-bolt, the relevant position on this support has two through holes, can should be fixed on this support by at least one U-bolt with nut by those through holes.
Preferably, those through holes are arranged on position corresponding with this at least one U-bolt on this junction plate.
In the utility model, but above-mentioned optimum condition any combination on the basis that meets this area general knowledge namely gets each preferred embodiment of the utility model.
Positive progressive effect of the present utility model is: can stablize, the fixing direction position of tensioner fluid cylinder in the horizontal direction safely, avoid causing fluid cylinder to damage because the reasons such as high wind cause fluid cylinder collision moon pool structure, and simultaneously simple in structure, easy for installation.

Fig. 2 is the elevation of a preferred embodiment of the present utility model.
Fig. 3 is the schematic diagram of the support in the preferred embodiment of the present utility model.
The specific embodiment
Embodiment of the present utility model describes with reference to the accompanying drawings.In Figure of description, element or device with similar structures or function will represent with identical component symbol.Accompanying drawing is each embodiment of the present utility model for convenience of explanation just, is not to carry out to the utility model the explanation of exhaustive, neither limit scope of the present invention.
Be a preferred embodiment of the present utility model as Figure 1-3.As shown in Figure 1, 2, in this embodiment, the anti-platform fastening devices of this tensioner fluid cylinder comprises a support 1 and at least one fixed part 2, and this fixed part 2 is fixedly connected on this support 1, is used in the horizontal direction fixedly fluid cylinder.
Fluid cylinder periphery in the horizontal direction is circular, for more firm fixedly fluid cylinder, the shape of this at least one fixed part 2 comprises one section circular arc at least, this section circular arc of these at least one parts can be complementary with the circular periphery shape of fluid cylinder like this, when fluid cylinder is subject to the wind-force effect and rocks, these fixed parts 2 are larger with the fluid cylinder contact area, can not damage because of collision.The quantity that those skilled in the art will appreciate that fixed part 2 can be selected as required, such as fluid cylinder weight heavier or typhoon can arrange a plurality of fixed parts 2 fix fluid cylinder multiple season.
As shown in Figure 3, in order to build the anti-platform fastening devices of this tensioner fluid cylinder at various offshore boring island more easily, this support 1 can be designed to comprise 11, two crossbeams 12 of a pedestal and a plate 13, and the two ends of these two crossbeams 12 are fixedly connected with this pedestal 11 with this junction plate 13 respectively.Preferably, this at least one fixed part 2 is U-bolt 2, and corresponding to each U-bolt 2, position corresponding with U-bolt 2 on this junction plate 13 is provided with through hole 131.For the fluid cylinder of diverse location, the distance to fluid cylinder on the platform is different.Be appreciated that ground, only need to change the length of crossbeam 12, just can make the anti-platform fastening devices of this tensioner fluid cylinder be applicable to various situation.The two ends of U-bolt 2 are directly fixed by through hole 131 usefulness nuts, connect simple and conveniently, and the circular arc portion of U-bolt 2 can be complementary with the circular periphery of fluid cylinder.Understandable, fixed part 2 also can be other shapes such as annular, take into account consider fixed part 2 and support 1 be connected and the shape of fixed part 2 and the circular periphery of fluid cylinder adapt, all applicable.
