Description

Technical Field

[0001] This utility model relates to the field of marine support components, and in particular to a modular combined support structure for marine transportation. Background Technology

[0002] In recent years, with the continuous maturation of modular design, processes, and construction technologies, the application areas, quantity, scale, and forms of modular construction have undergone significant changes. Modular design, construction, and installation have become the optimal choice for engineering projects across various fields. Modular unit modules are continuously developing towards larger, heavier, and more integrated sizes, with their weights reaching thousands or even tens of thousands of tons. Consequently, the technology and capabilities for land and sea transportation of modules, as well as seamless land-sea connections, have become crucial for modular engineering projects.

[0003] After large modular units are manufactured in the factory, they are typically lifted by a self-propelled modular transporter (SPMT) using its hydraulic lifting function to reach a predetermined position at the bottom of the module, achieving "self-loading." The module is then transported by land to the dock and rolled onto the designated stowage position on the large deck vessel, where it is finally lowered onto the marine support pier for "self-unloading." The load-bearing position of the SPMT module is the stress point during transportation, and the entire plane must be free of obstructions. Similarly, the support positions for the manufactured and marine modules must also be free of obstructions. However, in the module design, numerous pipes, small containers, and positioning columns, ranging in height from tens of centimeters to two or three meters, are arranged below the main bottom beam of the module, creating dense obstacles. This leads to problems such as structural complexity, insufficient space, height restrictions, inconvenient installation, difficulties in determining the structural stress points, and challenges in forming a complete foundation support. To overcome these obstacles, some manufacturers have designed transport frame beams, placed beneath the module's bottom beams to create space for manufacturing, land transport, and sea transport. However, these transport frame beams often weigh over a hundred tons, sometimes reaching several hundred tons, inevitably leading to significant material waste, greatly increasing manufacturing costs, and complicating the securing and reinforcement of the modules during sea transport. Furthermore, once the modules arrive at their destination, the frame beams need to be cut and removed before hoisting and installation, further increasing costs associated with untying and the waiting time for ships and hoisting equipment. Summary of the Invention

[0009] Furthermore, a first reinforcing rib is fixedly installed on the outer side of the side panel of the box, directly opposite the end of the end sealing plate of the box. A third reinforcing rib is fixedly installed on the outer side of the side panel of the box body, at the end opposite to the second reinforcing rib.

[0010] Furthermore, a main pad plate is fixedly installed on the bottom of the bottom panel of the box body, directly opposite the first reinforcing rib plate and / or the second reinforcing rib plate; secondary pad plates are also fixedly installed at both ends of the bottom of the bottom panel of the box body.

[0011] Furthermore, a fourth reinforcing rib is fixedly installed on the outer side of the side panel of the box. The two ends of the first reinforcing rib, the third reinforcing rib, and the fourth reinforcing rib are all fixedly connected between the bottom panel and the top panel of the box.

[0013] Furthermore, the length of the connecting plate is less than the length of the load-bearing wing plate, and the connecting plate is welded above the strong crossbeam of the ship's deck.

[0014] Furthermore, the height of the upper support structure of the module is 100cm greater than the height of the obstacle below the main beam at the bottom of the module, and the upper support structure of the module and the main beam at the bottom of the module are connected by a binding strap.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-11 As one embodiment of this utility model, a modular combined support structure 1 for marine transportation is disclosed. In this embodiment, the structure of a single combined support structure 1 is specifically described. Of course, in actual installation, multiple combined support structures 1 should be used to support the module and the ship deck 7. Specifically, the combined support structure 1 includes an upper support structure 11 for the module, a lower support structure 12 for the module, and a load-bearing structure 13 for the module. The upper support structure 11 of the module is installed below the main beam 3 at the bottom of the module, and the lower support structure 12 of the module is set on the ship deck 7. The lower part of the upper support structure 11 of the module is welded to the upper part of the lower support structure 12 of the module. The load-sharing structure 13 of the module is welded to the lower support structure 12 of the module and the ship deck 7.

[0020] Specifically, this embodiment is mainly used in the application environment of large modules in maritime transportation. The upper support structure 11, the lower support structure 12, and the load-sharing structure 13 of the module are all independent structures. During the design, the height, size, and quantity of each structure can be adjusted according to actual needs. The weight of the module is transferred to the lower support structure 12 through the upper support structure 11. In addition to transferring a part of the weight to the ship deck 7, the lower support structure 12 also transfers a part of the weight to the ship deck 7 through the load-sharing structure 13. Its structure and specifications are designed according to the strength of the ship deck 7 corresponding to the placement position.

[0021] The lower support structure 12 of the module is placed on the strong crossbeam 71 of the corresponding ship deck 7 via its main pad plate 124. The module load-sharing structure 13 is welded to the lower support structure 12 of the module and the ship deck 7 respectively. The upper support structure 11 and the lower support structure 12 of the module are independent structures. The upper support structure 11 and the lower support structure 12 of the module are welded together. The sum of the heights of the upper support structure 11, the lower support structure 12 of the module and the load-sharing structure 13 of the module forms the overall height of the combined support structure 1, which constitutes the support and binding reinforcement structure between the bottom main beam 3 of the large module and the ship deck 7. The large module refers to the modular cargo that needs to be transported.

[0022] Reference Figure 3 In some embodiments, the upper support structure 11 of the module in this utility model includes an upper support body 110, a hanging column 111, a support reinforcing rib plate 112, an upper support plate 113, and a plane adjustment plate 114. The upper support plate 113 is fixed above the upper support body 110 of the module, the support reinforcing rib plate 112 is disposed between the upper support body 110 of the module and the upper support plate 113, the plane adjustment plate 114 is installed above the upper support plate 113, and the hanging column 111 is welded to the outside of the upper support body 110 of the module.

[0023] Furthermore, in this embodiment, the height of the upper support structure 11 of the module is 100cm greater than the height of the obstacle below the main beam 3 at the bottom of the module. The upper support structure 11 of the module and the main beam 3 at the bottom of the module are connected by binding straps 6. That is, in this embodiment, the lifting column 111 is connected by binding straps 6, so that the upper support structure 11 of the module is not welded to the main beam 3 at the bottom of the module. After the module is transported to the destination, the other bindings of the module are removed, and the module can be lifted and unloaded. The structural diagram after the lifting is completed is shown in the figure. Figure 9 As shown, the implementation method is simpler and more efficient.

[0024] like Figure 3 As shown, in this specific embodiment, the upper support structure 11 of the module is made of steel pipe. Its diameter and height are set according to the height of the obstacle below the load-bearing position of the main beam 3 at the bottom of the module, the structure, and the magnitude of the load. Its overall height should be greater than the obstacle height by 100cm. The upper support structure 11 of the module is an independent structure design. The upper support structure 11 of the module is suspended below the load-bearing position of the main beam 3 at the bottom of the module using the binding strap 6 and the hanging column 111. It is rolled onto the ship together with the module. The upper support structure 11 of the module is lowered to a predetermined position above the upper panel of the box of the lower support structure 12 of the module placed on the deck 7 of the ship using the self-loading / self-unloading function of the SPMT transport vehicle group.

[0025] Furthermore, in this embodiment, the upper support plate 113 of the upper support structure 11 of the module is provided with the plane adjustment plate 114. The plane adjustment plate 114 is made of plywood material with a thickness of 10mm to 30mm. In actual operation, since the ship deck 7 may be uneven and the upper support structures 11 of the module are not on the same plane, the plane adjustment plate 114 can be used to adjust the horizontality of each upper support structure 11 of the module to ensure that the bottom main beam 3 of the module is on the opposite plane and to ensure the uniformity of the overall force. The material of the plane adjustment plate 114 is plywood, which increases the friction between the combined support structure 1 and the bottom main beam of the module, which is beneficial to improving the stress situation of the module.

[0026] Reference Figure 4 , Figure 5 Furthermore, the lower support structure 12 of the module described in this utility model includes a box structure composed of a bottom panel 120, a side panel 121, an upper panel 122, and an end sealing plate 126. Of course, in this embodiment, there are two side panels 121 and two end sealing plates 126. The upper support structure 11 of the module is fixed to the upper end of the upper panel 122 of the box body. Thrust plates 8 are fixedly installed at both ends of the bottom panel 120 of the box body. Specifically, the thrust plates 8 are set at both ends of the lower support structure 12 of the combined support structure 1 module and welded to the ship deck 7 to overcome the longitudinal force of the combined support structure 1.

[0027] Specifically, in this embodiment, the lower support structure 12 of the module adopts a welded steel plate box structure, which saves layout space and facilitates combination, arrangement, movement, disassembly, and the setting of reinforcing ribs, etc. The lower support structure 12 of the module is the main structure of the combined support structure 1. The width and length of the bottom panel 120 of the box are equal to the length and width of the upper panel 122 of the box. The length of the side panel 121 of the box is equal to the length of the bottom panel 120 and the upper panel 122 of the box. The height of the side panel 121 of the box depends on the height between the manufacturing site 2 and the bottom main beam 3 of the module in the module manufacturing design. Together with the height of the upper support structure 11 of the module, the thickness of the bottom panel 120 of the box, the thickness of the upper panel 122 of the box, and the main pad plate 124 of the box, the height of the combined support structure 1 is formed.

[0028] In this embodiment, the width and length of the bottom panel 120 of the box and the width of the top panel 122 of the box are greater than the width of the upper support body of the module. The bottom panel 120, the top panel 122, the side panel 121, and the end sealing plate 126 of the box together form the box structure. The box structure is stable and can overcome the vertical force, lateral force, and longitudinal force of the module.

[0029] Reference Figure 5 Based on the above embodiments, in this embodiment, a second reinforcing rib plate 128 is fixedly connected to the box structure, and a plurality of box connecting plates 123 are fixedly installed between the bottom panel 120 of the box and the upper panel 122 of the box. The plurality of box connecting plates 123 are distributed at the ends of the box end sealing plate 126 and the second reinforcing rib plate 128.

[0030] In this embodiment, the lower support structure 12 of the module is equipped with a second reinforcing rib plate, which is specially designed according to the distance of the deck strong beams of different ships, so that the same type of support can meet the usage needs of different deck strong beams and effectively reduce the usage cost of the module.

[0031] Reference Figure 5 Furthermore, in this embodiment, a first reinforcing rib plate 127 is fixedly installed on the outer side of the side panel 121 of the box body, directly opposite the end of the end sealing plate 126 of the box body. A third reinforcing rib 129 is fixedly installed on the outer side of the side panel 121 of the housing, at the end opposite to the second reinforcing rib 128.

[0032] Furthermore, in this embodiment, a main pad plate 124 is fixedly installed on the bottom of the bottom panel 120 of the box body, directly opposite the first reinforcing rib plate 127 and / or the second reinforcing rib plate 128; secondary pad plates 125 are also fixedly installed on both ends of the bottom of the bottom panel 120 of the box body.

[0033] Reference Figure 4 Specifically, in this embodiment, the lower support structure 12 of the module is provided with the main pad plate 124 of the box body below the bottom panel 120 of the box body, the end sealing plate 126 of the box body, or the second reinforcing rib plate 128. Part of the weight of the module is transferred to the ship deck strong beam 71 through the main pad plate 124 of the box body, which can more effectively transfer the weight of the module to the strong structure of the ship, improve the local strength of the ship, and improve the local load capacity of the ship.

[0034] In addition, a relatively large space is provided between the main pads 124 of the box in this embodiment, which effectively avoids the impact of the unevenness of the ship deck 7 on the setting of the bottom panel 120 of the box, reduces the need for large-area deck cleaning, and effectively improves work efficiency.

[0035] Reference Figure 5 Preferably, in this embodiment, a fourth reinforcing rib plate 1201 is also fixedly installed on the outer side of the side panel 121 of the box body. The two ends of the first reinforcing rib plate 127, the third reinforcing rib plate 129 and the fourth reinforcing rib plate 1201 are all fixedly connected between the bottom panel 120 and the top panel 122 of the box body.

[0036] The lower support structure 12 of the module described in this embodiment is provided with a fourth reinforcing rib, which can stably support and effectively transmit the module's gravity, lateral force and longitudinal force, etc., of the upper support structure 11 of the module.

[0037] Reference Figure 6 In some embodiments, the module load-sharing structure 13 of this utility model includes a load-sharing wing plate 130, a load-sharing reinforcing rib plate 131, and a connecting plate 132. The load-sharing wing plate 130 is connected to the box connecting plate 123, the load-sharing reinforcing rib plate 131 is fixed above the load-sharing wing plate 130, and the connecting plate 132 is welded between the load-sharing wing plate 130 and the ship deck 7.

[0038] Specifically, in this embodiment, the length of the connecting plate 132 is less than the length of the load-sharing wing plate 130.

[0039] Preferably, in this embodiment, the connecting plate 132 is welded only after the SPMT transport vehicle group 4 has been removed from the bottom main beam 3 of the module. This effectively avoids situations where the gap between the load-bearing wing plate 130 and the ship deck 7 is too small and needs to be cut, or the gap is too large and needs to be filled, due to the unevenness of the ship deck 7. This effectively improves work efficiency and ensures welding quality.

[0040] Furthermore, welding above the ship's deck strong beam 71 can more effectively transfer the module's gravity and lateral force to the ship's strong structure, improving the ship's local strength and enhancing its local load-bearing capacity.

[0041] In this embodiment, the connecting plate 132 is welded above the strong crossbeam 71 of the ship deck 7, which can more effectively transfer the gravity and lateral force of the module to the strong structure of the ship, improve the local strength of the ship, and increase the local load capacity of the ship. When the combined support structure 1 described in this embodiment is reused, the connecting plate 132 can be cut and replaced with a new plate, which greatly reduces the material and processing costs.

[0042] like Figures 6 to 8 As shown, in this embodiment, the distance between the module load-sharing structure 13 and the SPMT transport vehicle group 4 is greater than 200cm. When the distance between the module load-sharing structure 13 and the SPMT transport vehicle group 4 is greater than 200cm, the load-sharing wing plate 130 can be welded to the corresponding position of the box connecting plate 123 at the manufacturing site 2 to form a lower integral installation on the corresponding position of the ship deck. When the distance between the module load-sharing structure 13 and the SPMT transport vehicle group 4 is less than 200cm, the load-sharing wing plate 130 is welded to the box connecting plate 123 only after the SPMT transport vehicle group 4, together with its top SPMT transport tooling 5, has been removed from the bottom main beam 3 of the module. This effectively solves the problem of the channel between the module gravity load-sharing space and the SPMT transport vehicle group 4.

[0043] In summary, this embodiment, through its independently designed modular support structure, enables rapid installation, assembly, and disassembly. The overall height can be controlled according to actual conditions and requirements, offering advantages such as simple structure, convenient construction, compatibility with different ship types, and reusability. Furthermore, the optimized structural design reduces the difficulty of securing and reinforcing large modules during maritime transport, significantly lowering transportation costs and greatly meeting the requirements for safe securing and efficient installation during project transport. Simultaneously, it effectively reduces the amount of materials and welding work required.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
