Description

Technical Field

[0001] This utility model relates to the field of marine oil and gas transportation technology, and in particular to a clamping device for a flexible hose. Background Technology

[0002] Flexible pipes are key dynamic pipelines used to connect offshore fixed platforms and floating production facilities (such as FPSO floating production storage and offloading units, semi-submersible platforms, tension leg platforms, etc.) to subsea production systems (such as subsea wellheads, subsea pipeline terminals). Subsea flexible pipes are multi-layered composite dynamic pipelines whose core value lies in utilizing their "flexibility" to reliably connect violently swaying floating facilities or offshore fixed platforms to fixed facilities located on the seabed, thereby efficiently and safely transporting fluids such as oil and gas. They are an indispensable key equipment for deepwater oil and gas development.

[0003] During the use of flexible hoses, to prevent the hose from heaving due to environmental conditions, a mooring line is typically connected to the hose, and then the mooring line is connected to a descent control mechanism on the seabed. When connecting the mooring line to the flexible hose, a clamping device is usually fixed to the hose, and then the mooring line is connected to this clamping device. However, because existing conventional clamping devices are fixedly connected to the flexible hose, when the mooring line swings or rotates, it causes the clamping device and the flexible hose to rotate together, resulting in the flexible hose being subjected to torque loads, which reduces the service life of the flexible hose. Utility Model Content

[0006] Furthermore, the rotating connector includes a first connector and a second connector that is detachably and fixedly connected to the first connector. The first connector has a first semi-circular hole, and the second connector has a second semi-circular hole. When the first connector and the second connector are connected, the first semi-circular hole and the second semi-circular hole can be assembled into a circular assembly hole. The diameter of the assembly hole is larger than the diameter of the connecting part. The first connecting hole is provided on the first connector and / or the second connector.

[0007] Furthermore, the first connector is provided with a second connecting hole, and a connecting plate is fixedly provided on the second connector.

[0008] Furthermore, the first connecting member includes a first flange fixedly disposed on the first sub-clamp and a second flange fixedly disposed on the second sub-clamp, the first flange and the second flange being connected by a plurality of first bolts.

[0009] Furthermore, the first sub-clamp has multiple grooves on its side, which are spaced apart along the axial direction of the clamp body. The second sub-clamp has multiple protrusions on its side, which are also spaced apart along the axial direction of the clamp body. When the first sub-clamp and the second sub-clamp are connected, the multiple protrusions are embedded in the multiple grooves one by one.

[0010] Furthermore, the inner walls of both the first and second sub-clamps are provided with a first rubber layer.

[0011] Furthermore, a tethering plate is hinged to the first connecting hole, and the tethering cable is connected to the tethering plate.

[0012] Furthermore, it also includes a first horn segment and a second horn segment, wherein the first horn segment includes a first upper horn segment and a first lower horn segment, the first end of the first upper horn segment is fixedly connected to the first end of the first sub-clamp, the first end of the first lower horn segment is fixedly connected to the first end of the second sub-clamp, and the first upper horn segment and the first lower horn segment are detachably and fixedly connected by a second connector to form the first horn segment; the second horn segment includes a second upper horn segment and a second lower horn segment, the first end of the second upper horn segment is fixedly connected to the second end of the first sub-clamp, the first end of the second lower horn segment is fixedly connected to the second end of the second sub-clamp, and the second upper horn segment and the second lower horn segment are detachably and fixedly connected by a third connector to form the second horn segment; the diameter of the first horn segment gradually increases from its first end to its second end; the diameter of the second horn segment gradually increases from its first end to its second end.

Then, one end of the mooring cable is connected to the first connecting hole on the rotating connector, and the other end of the mooring cable is connected to the seabed descent control system. Since the rotating connector is rotatably mounted on the clamp body, and the first and second limiting baffles on the clamp body can restrict the rotating connector from moving along the axial direction of the clamp body, when the mooring cable swings and rotates back and forth in the sea, the mooring cable will only drive the rotating connector to rotate, thus not affecting the clamp body and the flexible hose. The mooring cable only maintains tension along the axial direction of the flexible hose on the clamp body and the flexible hose, that is, it will not generate torsional load on the flexible hose, thereby greatly improving the service life of the flexible hose.

[0049] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0050] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] Please see Figures 1 to 10 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0053] This utility model provides a clamping device for flexible hoses, such as... Figures 1 to 5 As shown, the clamping device 100 includes a clamping body 10 and a rotating connector 20. The clamping body 10 includes a first sub-clamp 11 and a second sub-clamp 12, which are detachably and fixedly connected by a first connector 13, thereby used to clamp the flexible hose 200 between the first sub-clamp 11 and the second sub-clamp 12. The clamping body 10 is provided with a first limiting baffle 101 and a second limiting baffle 102. The first limiting baffle 101 and the second limiting baffle 102 are spaced apart along the axial direction of the clamp body 10, thus forming a connecting portion 103 between the first limiting baffle 101 and the second limiting baffle 102; the rotating connector 20 is rotatably disposed on the connecting portion 103, and the first limiting baffle 101 and the second limiting baffle 102 can restrict the rotating connector 20 from moving along the axial direction of the clamp body 10, and the rotating connector 20 is provided with a first connecting hole 201 for connecting the tether cable 300.

[0054] The beneficial effects of the flexible hose clamping device of the present invention are: when in use, such as Figure 10As shown, the flexible hose 200 is clamped between the first sub-clamp 11 and the second sub-clamp 12, thereby achieving relative fixation between the flexible hose 200 and the clamp body 10. Then, one end of the mooring cable 300 is connected to the first connection hole 201 on the rotating connector 20, and the other end of the mooring cable 300 is connected to the seabed descent control system 400. Since the rotating connector 20 is rotatably mounted on the clamp body 10, and the first limiting baffle 101 and the second limiting baffle 102 on the clamp body 10 can restrict the rotating connector 20 from moving along the axial direction of the clamp body 10, when the mooring cable 300 swings and rotates back and forth in the sea, the mooring cable 200 will only drive the rotating connector 20 to rotate, thus not affecting the clamp body and the flexible hose. The mooring cable 300 only maintains tension on the clamp body and the flexible hose along the axial direction of the flexible hose 200, that is, it will not generate torsional load on the flexible hose 200, thereby greatly improving the service life of the flexible hose.

[0055] Furthermore, such as Figure 6 and Figure 7 As shown, in this embodiment, the rotating connector 20 includes a first connector 21 and a second connector 22. The first connector 21 and the second connector 22 are detachably and fixedly connected. The first connector 21 is provided with a first semi-circular hole 210, and the second connector 22 is provided with a second semi-circular hole 220. When the first connector 21 and the second connector 22 are connected, the first semi-circular hole 210 and the second semi-circular hole 220 can be assembled into a circular assembly hole 230, and the diameter of the assembly hole 230 is larger than the diameter of the connecting part 103. Specifically, the first connecting hole 201 is provided on the first connector 21. This design allows the rotating connector 20 to be detachably and fixedly connected as a first connector 21 and a second connector 22, facilitating the connection and assembly of the rotating connector 20 with the card holder body 10. By making the diameter of the assembly hole 230 formed by the combination of the first semi-circular hole 210 on the first connector 21 and the second semi-circular hole 220 on the second connector 22 larger than the diameter of the connecting part 103 on the card holder body 10, the rotating connector 20 and the card holder body 10 are fitted with a clearance, enabling the rotating connector 20 to rotate relative to the card holder body 10. This design is simple in structure and low in cost.

[0056] It should be noted that in other optional embodiments, the first connection hole 201 may be provided on the second connector 22; or in other optional embodiments, the first connection hole 201 for connecting the cable 300 may be provided on both the first connector 21 and the second connector 22. When the first connection hole 201 is provided on both the first connector 21 and the second connector 22, the first connection hole 210 of one of them may be used as a spare.

[0057] Specifically, such as Figure 7As shown, the first connecting body 21 has a second connecting hole 211, and the second connecting body 22 has a connecting plate 221 fixedly mounted on it. The connecting plate 221 has a third connecting hole 222. A bolt is inserted through the second connecting hole 211 and the third connecting hole 222 to connect the first connecting body 21 and the second connecting body 22. The structure is simple and easy to assemble and disassemble.

[0058] Furthermore, such as Figure 2 and Figure 9 As shown, the first connecting member 13 includes a first flange 131 fixedly mounted on the first sub-clamp 11 and a second flange 132 fixedly mounted on the second sub-clamp 12. The first flange 131 and the second flange 132 are connected by a plurality of first connecting bolts 133. This configuration is simple in structure, convenient to disassemble and assemble, and has strong connection stability.

[0059] Furthermore, in order to improve the axial stability of both the first sub-clamp 11 and the second sub-clamp 12, preferably, as follows: Figure 5 As shown, the first sub-clamp 11 has multiple grooves 110 on its side, which are spaced apart along the axial direction of the clamp body 10. Correspondingly, the second sub-clamp 12 has multiple protrusions 120 on its side that are adapted to the grooves 110, which are also spaced apart along the axial direction of the clamp body 10. When the first sub-clamp 11 and the second sub-clamp 12 are connected, the multiple protrusions 120 on the second sub-clamp 12 are fitted one-to-one into the multiple grooves 110 on the first sub-clamp 11. With this configuration, when the first sub-clamp 11 and the second sub-clamp 12 are connected and fixed by the first connector 13, the protrusions 120 on the second sub-clamp 12 cooperate with the grooves 110 on the first sub-clamp 11, thereby further ensuring that the first sub-clamp 11 and the second sub-clamp 12 can move relative to each other along the axial direction of the clamp body 10, thus ensuring the stability of the connection between the first sub-clamp 11 and the second sub-clamp 12.

[0060] Furthermore, in order to improve the clamping force of the clamping body 10 on the flexible hose 200, preferably, as follows: Figure 9 As shown, in this embodiment, a first rubber layer 104 is provided on the inner wall of both the first sub-clamp 11 and the second sub-clamp 12. The provision of this first rubber layer 104 increases the frictional force between the flexible hose and the first sub-clamp 11 and the second sub-clamp 12, thereby further enhancing the stability of the connection between the clamp body 10 and the flexible hose 100. Preferably, the surface of the first rubber layer can be made relatively rough, thereby increasing the frictional force between the clamp body 10 and the flexible hose 100.

[0061] Furthermore, to prevent the tether 200 from pulling the flexible hose 100 up and down in the axial direction when it swings back and forth along the axial direction, preferably, as follows: Figure 3 As shown, a cable tether plate 202 is hinged to the first connection hole 201 on the rotating connector 20, and the cable 300 is connected to the cable tether plate 202. With this configuration, when the cable 300 swings along the axial direction of the flexible hose 200, the cable 300 pulls the cable tether plate 202 hinged to the rotating connector 20 to rotate, causing the cable tether plate 202 to rotate relative to the rotating connector 20. This prevents the rotating connector 20, the clamp body 10, and the flexible hose from swinging vertically, thus ensuring the stability of the flexible hose during operation.

[0062] Furthermore, such as Figure 2 and Figure 5 As shown, in this embodiment, the card-holding device 100 further includes a first horn segment 30 and a second horn segment 40. The first horn segment 30 includes a first upper horn segment 31 and a first lower horn segment 32. The first end of the first upper horn segment 31 is fixedly connected to the first end of the first sub-card 11, and the first end of the first lower horn segment 32 is fixedly connected to the first end of the second sub-card 12. The first upper horn segment 31 and the first lower horn segment 32 are detachably and fixedly connected by a second connector 33 to form the first horn segment 30. Similarly, the second horn segment 40 includes a second upper horn segment 41 and a second lower horn segment 42. The first end of the second upper horn segment 41 is fixedly connected to the first end of the first sub-card 11. The second end of the sub-clamp 11 is fixedly connected, and the first end of the second lower horn section 42 is fixedly connected to the second end of the second sub-clamp 12. The second upper horn section 41 and the second lower horn section 42 are detachably and fixedly connected by a third connector 43 to form the second horn section 40. Specifically, the diameter of the first horn section 30 gradually increases from its first end to its second end, that is, from the end connected to the first end of the clamp body to the direction away from the first end of the clamp body; the diameter of the second horn section 40 gradually increases from its first end to its second end, that is, from the end connected to the second end of the clamp body to the direction away from the second end of the clamp body. With this configuration, by setting the first horn section 30 and the second horn section 40 at both ends of the clamp body 10, when the flexible hose is subjected to a large external force and bends, the inner walls of the first horn section 30 and the second horn section 40 can limit the bending deformation of the flexible hose from exceeding its maximum bending radius, thereby further ensuring the service life of the flexible hose.

[0063] Furthermore, to reduce wear and scratches on the flexible hose caused by the inner walls of the first horn segment 30 and the second horn segment 40, preferably, in this embodiment, a second rubber layer 301 is provided on the inner walls of the first horn segment, namely the inner sidewalls of the first upper horn segment 31 and the first lower horn segment 32. Similarly, a second rubber layer 301 is also provided on the inner walls of the second horn segment, namely the inner sidewalls of the second upper horn segment 41 and the second lower horn segment 42. Preferably, the surface of the rubber layer 301 can be made into a smooth surface.

[0064] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the second connecting member 33 includes a first wing plate 331 fixedly disposed on the first upper horn section 31 and a second wing plate 332 fixedly disposed on the first lower horn section 32. The first wing plate 321 and the second wing plate 332 are connected by a plurality of second connecting bolts 333. Similarly, the third connecting member 43 includes a third wing plate 431 fixedly disposed on the second upper horn section 41 and a fourth wing plate 432 fixedly disposed on the second lower horn section 42. The third wing plate 431 and the fourth wing plate 432 are connected by a plurality of third connecting bolts 433.

[0065] Specifically, to facilitate the connection and positioning of the first upper horn segment 31 and the first lower horn segment 32, positioning holes are provided on the first wing plate 331 and the second wing plate 332 in this embodiment. Similarly, to facilitate the connection and positioning of the second upper horn segment 41 and the second lower horn segment 42, positioning holes are also provided on the third wing plate 431 and the fourth wing plate 432. When connecting the first upper horn segment 31 and the first lower horn segment 32, and when connecting the second upper horn segment 41 and the second lower horn segment 42, positioning pins can be inserted into the positioning holes first.

[0066] Specifically, the clamping device 100 is made entirely of high-strength carbon steel, ensuring structural strength while maintaining a relatively light weight. Preferably, to prevent corrosion of the clamping device in seawater, a zinc block 50 is also provided on the clamping body 10 in this embodiment. The zinc block 50, by preventing oxidation-reduction reactions, effectively prevents corrosion of the clamping device and significantly extends its service life.

[0067] In summary, the flexible hose clamping device of this invention effectively solves the problem that existing flexible hose clamping devices easily cause the flexible hose to twist and generate torque, thereby reducing the service life of the flexible hose. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0068] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
