Description

Technical Field

[0001] The present invention relates to the technical field of support structures for marine transportation, and particularly to a support structure for the marine transportation of large modules. Background Art

[0002] During the marine transportation of some large modules, the motion acceleration is relatively large. When the center of gravity height of the column foot reaches a certain level, an uplift force may occur at the column foot. To address this problem, the common practice is to weld the column foot to the pier to restrict the movement trend of the column foot.

[0003] Although the welding method can ensure the overall stability of the module on the hull, this method is not convenient for repeated use. Repeated welding of the column foot is likely to cause thermal cracks and other situations, which are very likely to lead to problems such as insufficient firmness of the welding between the column foot and the hull. Moreover, due to the large number of column feet, if each column foot is welded, the workload is huge and requires a large number of workers and welding machines. Summary of the Invention

[0004] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a support structure for the marine transportation of large modules, which can effectively overcome the uplift force generated during transportation and is convenient for repeated disassembly and reuse.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A support structure for the marine transportation of large modules, comprising a hull, a deck integrally formed with the hull, a support assembly, and bolt fasteners;

[0007] The hull is composed of several chambers, and rib positions are equally spaced in each chamber;

[0008] The support assembly includes an I-beam welded to the deck and a column base plate disposed on the top of the I-beam. A column foot column is fixed to the top of the column base plate. Fixed pads are welded to both sides of the top of the I-beam, and the column base plate is fitted between the two fixed pads;

[0009] A fixed pressing plate is disposed on the top of each fixed pad, and the fixed pressing plate is fixed to the upper surfaces of the fixed pad and the column base plate by bolt fasteners.

[0010] As a preferred solution of the present invention, the I-beam is welded to the tops of two rib positions in the hull.

[0011] Through the above technical solution design, by welding the I-beam to the tops of two rib positions, the structural supporting force of the rib positions can be used to enhance the stability of the I-beam on the hull. At the same time, it can also avoid the problem that the deck is damaged due to the gravity of the support assembly when the I-beam is welded to the bottom of the deck without rib positions.

[0012] As a preferred solution of the present invention, a first threaded through hole is provided on the top of the fixed pressure plate for convenient passage of a bolt fastener, and a second threaded through hole is provided on the top of the fixed pad at a position corresponding to the first threaded through hole.

[0013] Through the above technical solution design, the first threaded through hole and the second threaded through hole can well connect the fixed pad and the fixed pressure plate to form a stable connection structure therebetween, thereby utilizing the fixed pressure plate to achieve the pressing and fixing of the column base plate.

[0014] As a preferred solution of the present invention, at least two groups of bolt fixing members are arranged between each fixed pressure plate and the fixed pad.

[0015] Through the above technical solution design, the fixed pressure plate and the fixed pad are connected by means of bolt fasteners, which, on the one hand, facilitates the later separation of the fixed pressure plate and the fixed pad, and on the other hand, can overcome a certain upward pull force through the bolt fasteners.

[0016] As a preferred embodiment of the present invention, it also includes a filling pad.

[0017] When the upper surface of the column base plate is lower than the upper surface of the fixed pad plate, the filling pad plate is placed on the upper surface of the column base plate and flush with the upper surface of the fixed pad plate;

[0018] When the upper surface of the column base plate is higher than the upper surface of the fixed pad plate, the filling pad plate is placed on the upper surface of the fixed pad plate and is flush with the upper surface of the column base plate.

[0019] As a preferred solution of the present invention, one end of the bolt fixing piece is welded to the I-beam, and the other end is threadedly connected with a nut.

[0020] As a preferred solution of the present invention, a plurality of telescopic sliding holes are opened at the top of the inner cavity of the telescopic cavity, and a telescopic sliding column is slidably connected in each telescopic sliding hole. A fixed plate is fixedly connected to the inner cavity of the telescopic cavity near the middle, and the bottom of the telescopic sliding column movably passes through the fixed plate and is fixedly connected to the top of the extrusion block.

[0021] Through the above technical solution design, the stability of the extrusion block during sliding can be effectively guaranteed.

[0022] As a preferred solution of the present invention, a fixed block is fixedly sleeved on the rod body of the telescopic slide and at a position located on the top of the fixed plate, the top of the fixed block is fixedly connected to a compression spring sleeved on the telescopic slide, and the top of the compression spring is fixedly connected to the top of the inner wall of the telescopic cavity.

[0023] Through the above technical solution design, by means of the designed compression spring, a counterthrust can be effectively generated, thereby pushing the extrusion block and the extrusion gasket to fit more tightly on the top of the filling backing plate.

[0024] As a preferred solution of the present invention, the inner walls of the extrusion block and the telescopic cavity are both smooth mirror structures, and the extrusion block is slidably connected to the inner wall of the telescopic cavity. A layer of extrusion gasket made of rubber is fixedly connected to the bottom of the extrusion block, and the extrusion gasket fits tightly on the top of the filling backing plate.

[0025] Through the above technical solution design, it is convenient for the extrusion block to slide, and at the same time, the extrusion gasket can increase the friction with the filling backing plate to achieve a better fitting effect.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. By welding the support assembly to the tops of two rib positions in the hull, the present invention can utilize the support of the rib positions to ensure the stability of the support assembly on the hull, and at the same time, it can also prevent the gravity of the support assembly from damaging the hull. The bolt fixing parts cooperate with the fixing backing plates, fixing pressing plates and filling backing plates, and can effectively snap and fix the column base plate stably between the two fixing backing plates to form a good positioning structure, thereby overcoming the uplift force generated during transportation and ensuring the stability of the column base plate and the foot column on the hull. It only needs to weld the I-beam welded with the fixing backing plate on the hull in the early stage, and then place the column base plate between the two fixing backing plates when using this structure, without the need for complicated welding work. The binding and unbinding are simple, which can ensure the rapid progress of the binding work, and each component can be recycled to avoid waste of materials, and is suitable for popularization.

[0028] 2. By providing structures such as telescopic sliding columns, compression springs, extrusion blocks and extrusion gaskets in the fixing pressing plate, the present invention can effectively use the return thrust of the extrusion block to make the fixing pressing plate fit more tightly on the fixing backing plate and the filling backing plate when the fixing pressing plate is attached to the filling backing plate, and can push the filling backing plate to fit more tightly with the column base plate, so that the column base plate and the foot column can be more firmly stabilized on the I-beam, and finally the fixing effect of this structure is better.

Detailed implementation manners

[0036] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] Please refer to Figure 1-6 , a support structure for large - module marine transportation of the present invention includes a hull 1, a deck 2 integrally formed with the hull 1, a support assembly 4 and a bolt fixing part 10;

[0038] The hull 1 is composed of several chambers, and rib positions 3 are equidistantly arranged in each chamber;

[0039] The support assembly 4 includes an I - beam 5 welded to the deck 2 and a column base plate 6 arranged on the top of the I - beam 5. A column base vertical column 7 is fixed to the top of the column base plate 6. Fixed backing plates 8 are welded to both sides of the top of the I - beam 5, and the column base plate 6 is fitted between the two fixed backing plates 8;

[0040] A fixed pressing plate 9 is arranged on the top of each fixed backing plate 8, and the fixed pressing plate 9 is fixed to the upper surfaces of the fixed backing plate 8 and the column base plate 6 through the bolt fixing part 10.

[0041] Furthermore, the I-beam 5 is welded to the tops of two rib positions 3 in the hull 1; by welding the I-beam 5 to the tops of the two rib positions 3, the structural support force of the rib positions 3 can be utilized to enhance the stability of the I-beam 5 on the hull 1. At the same time, it can also avoid the problem that the deck 2 is damaged due to the gravity of the support assembly 4 when the I-beam 5 is welded to the bottom of the deck 2 where there is no rib position 3.

[0042] Furthermore, a first threaded through hole 12 for facilitating the passing of the bolt fastener 10 is provided at the top of the fixed pressing plate 9, and a second threaded through hole 13 is provided at the top of the fixed backing plate 8 at a position corresponding to the first threaded through hole 12; the first threaded through hole 12 and the second threaded through hole 13 can well connect the fixed backing plate 8 and the fixed pressing plate 9 to form a stable connection structure therebetween, so as to use the fixed pressing plate 9 to achieve the pressing and fixing of the column base plate 6.

[0043] Furthermore, at least two groups of bolt fasteners 10 are provided between each fixed pressing plate 9 and the fixed backing plate 8; connecting the fixed pressing plate 9 and the fixed backing plate 8 by means of the bolt fasteners 10, on the one hand, facilitates the later separation of the fixed pressing plate 9 and the fixed backing plate 8, and on the other hand, can overcome a certain uplift force through the bolt fasteners 10.

[0044] Furthermore, a filling backing plate 11 is also included.

[0045] When the upper surface of the column base plate 6 is lower than the upper surface of the fixed backing plate 8, the filling backing plate 11 is placed flush with the upper surface of the column base plate 6 and the upper surface of the fixed backing plate 8.

[0046] When the upper surface of the column base plate 6 is higher than the upper surface of the fixed backing plate 8, the filling backing plate 11 is placed flush with the upper surface of the fixed backing plate 8 and the upper surface of the column base plate 6.

[0047] Furthermore, one end of the bolt fastener 10 is welded to the I-beam 5, and the other end is threadedly connected with a nut.

[0048] Furthermore, a plurality of telescopic sliding holes 15 are provided at the top of the inner cavity of the telescopic cavity 14, and a telescopic sliding column 17 is slidably connected in each telescopic sliding hole 15. A fixing plate 16 is fixedly connected at a position close to the middle of the inner cavity of the telescopic cavity 14. The bottom of the telescopic sliding column 17 movably penetrates through the fixing plate 16 and is fixedly connected to the top of the extrusion block 20; through the designed telescopic sliding column 17 and the fixing plate 16, the stability of the extrusion block 20 during sliding can be effectively ensured.

[0049] Further, a fixing block 18 is fixedly sleeved on the rod body of the telescopic sliding column 17 at a position above the fixing plate 16. The top of the fixing block 18 is fixedly connected to a compression spring 19 sleeved on the telescopic sliding column 17, and the top of the compression spring 19 is fixedly connected to the top of the inner wall of the telescopic cavity 14. Through the designed compression spring 19, an effective reaction force can be generated, thereby pushing the extrusion block 20 and the extrusion gasket 21 to fit more closely on the top of the filling cushion plate 11.

[0050] Further, the inner walls of the extrusion block 20 and the telescopic cavity 14 are both smooth mirror structures, and the extrusion block 20 is slidably connected to the inner wall of the telescopic cavity 14. A layer of extrusion gasket 21 made of rubber is also fixedly connected to the bottom of the extrusion block 20, and the extrusion gasket 21 is closely attached to the top of the filling cushion plate 11. The appearance of this design can facilitate the sliding of the extrusion block 20, and at the same time, the extrusion gasket 21 can increase the friction with the filling cushion plate 11 to achieve a better fitting effect.

[0051] It should be noted that since it is difficult to determine the exact value of the thickness of the column base plate 6 or the fixing cushion plate 8 when assembling the support assembly 4, there will be a certain height difference between the upper surface of the column base plate 6 and the upper surface of the fixing cushion plate 8.

[0052] When the thickness of the column base plate 6 is lower than that of the fixing cushion plate 8, the filling cushion plate 11 needs to be placed on the column base plate 6 so that the upper surface of the filling cushion plate 11 is flush with the upper surface of the fixing cushion plate 8, thereby facilitating the lower surface of the fixing pressing plate 9 to fit on the upper surfaces of the fixing cushion plate 8 and the filling cushion plate 11, and facilitating the fixing pressing plate 9 to fasten the column base plate 6 by means of the bolt fixing member 10, as Figure 1 shown;

[0053] When the thickness of the column base plate 6 is higher than that of the fixing cushion plate 8, the filling cushion plate 11 needs to be placed on the fixing cushion plate 8 so that the upper surface of the filling cushion plate 11 is flush with the upper surface of the column base plate 6, thereby facilitating the lower surface of the fixing pressing plate 9 to fit on the upper surfaces of the filling cushion plate 11 and the column base plate 6, and facilitating the fixing pressing plate 9 to fasten the column base plate 6 by means of the bolt fixing member 10. This is not shown in the figure.

[0054] A good stable structure can be formed among the column base plate 6, the column base column 7, the fixing cushion plate 8, the fixing pressing plate 9 and the filling cushion plate 11, so that the stability of the combined assembly can reach the best, which can avoid loosening between components caused by shaking during transportation and ensure transportation safety.

[0055] When using the present invention (working principle), before performing the binding work, first weld the I-beam 5 welded with two fixed backing plates 8 to two rib positions 3 of the hull 1 to achieve the positioning and fixing of the I-beam 5. Place the column base column 7 with the column base plate 6 between the two fixed backing plates 8, and then place the filling backing plate 11 on the top of the column base plate 6 so that the upper surface of the filling backing plate 11 is flush with the upper surface of the fixed backing plate 8. Then, press the fixed pressing plate 9 on the upper surfaces of the fixed backing plate 8 and the filling backing plate 11, and pass through the second threaded perforation 13 on the fixed pressing plate 9 through the screw rod of the bolt fixing member 10 to achieve the fastening of the fixed pressing plate 9 on the upper surface of the fixed backing plate 8, and then screw the nut into the screw rod;

[0056] During the process of screwing in the nut, it will continuously push the fixed pressing plate 9 downward and make the extrusion gasket 21 fit on the top of the filling backing plate 11. Due to the continuous screwing in of the nut, the extrusion block 20 will gradually push the compression spring 19 to deform (compress) through the fixed block 18, and the telescopic sliding column 17 will further slide into the telescopic sliding hole 15 until the bottom of the extrusion gasket 21 is at the same horizontal plane as the bottom of the fixed pressing plate 9. At this time, a part of the fixed pressing plate 9 directly fits tightly on the top of the filling backing plate 11, and the extrusion gasket 21 at the telescopic cavity 14 also fits tightly on the top of the filling backing plate 11. Finally, through the return thrust from the compression spring 19, the extrusion block 20 and the extrusion gasket 21 fit more tightly on the filling backing plate 11 to achieve a better stabilizing effect on the filling backing plate 11. Finally, through the pressing and fastening of the bolt fixing member 10 on the fixed backing plate 8 and the fixed pressing plate 9, the column base plate 6 and the column base column 7 are fastened and stabilized through the fixed pressing plate 9 and the filling backing plate 11.

[0057] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
