Description

Technical Field

[0001] This utility model relates to the field of marine engineering equipment transportation technology, and in particular to a modular adjustable marine large-scale modular transport support frame system. Background Technology

[0002] Currently, large offshore modules (such as FPSO modules, jacket foundations, and wind turbine foundations) are typically loaded and transported using welded tubular / steel deck support frames (DSF). Typical technical solutions include integral welded tubular truss structures and locally reinforced support frames.

[0003] Currently available modular adjustable large-scale marine transport support frame systems are non-reusable, resulting in significant material waste: the DSF (Diverterless Support Frame) is welded to the deck and modules, requiring flame cutting for dismantling after transport, leading to complete structural destruction and rendering it unusable. For example, in one FPSO module transport project, the DSF consumed approximately 800 tons of steel, and only scrap steel (less than 20% of the value of new material) could be recycled after dismantling. Adaptability is poor, and adjustments are inflexible: once welded, it's difficult to modify the support point position or height. If the module design changes (e.g., adjusting the leg spacing), the entire DSF needs to be remanufactured. Different projects require customized DSFs, making universal use impossible. Repair and partial replacement are difficult: if local deformation or cracking occurs during transport, large-area cutting and repair, or even complete replacement, are required. After cutting, the welded areas need re-corrosion protection, but the quality of on-site spraying is difficult to guarantee. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies, such as reusability, serious material waste, poor adaptability, inflexible adjustment, maintenance, and difficulty in partial replacement, and to propose a modular adjustable marine large-scale modular transport support frame system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular adjustable marine large-scale modular transport support frame system, including a top support frame, in which multiple top load-bearing beams are installed, and upper modular column bases are installed on the outer wall of each top load-bearing beam. Multiple intermediate support frames are installed at the bottom end of the top support frame, and a bottom longitudinal load-bearing beam is fixed on the outer side of each intermediate support frame located below the top support frame. A connecting block is installed at the opposite end of each intermediate support frame and the top support frame, and an internal diagonal brace is installed between two connecting blocks.

[0006] Preferably, each of the intermediate support frames has a bottom mounting plate fixed to its bottom end.

[0007] Preferably, there are multiple upper block column base points, and multiple upper block column base points are installed on the outer side of each top load-bearing beam.

[0008] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0009] In this invention, each component is formed into a unit. The supporting column unit is the main load-bearing component, which adopts a box-section welded structure and has internal stiffening ribs. The lateral stabilizing unit is an H-shaped steel beam connecting the column, which transmits lateral loads. The diagonal bracing unit consists of diagonally arranged internal diagonal braces to improve anti-overturning capacity. The traditional integrally welded DSF is decomposed into several standardized welding units, which are controllably cut and separated at preset positions. The cut surfaces are reserved with repair bevels to support secondary welding and reassembly. Furthermore, the surface of each component is coated with a multi-layer repairable anti-corrosion coating to ensure corrosion resistance after cutting and repair. Through the flexible arrangement and combination of standardized units, this device can dynamically adjust the number and position of support points according to the center of gravity distribution of different blocks, increasing the deck stress points from the traditional 4-6 fixed points to 8-12 adjustable support points. Each modular unit adopts a box-shaped beam and internal diagonal bracing composite structure. Through the stress gradient transmission design inside the welding unit, the concentrated load is gradually dispersed. Actual test data shows that the load diffusion angle has been increased from 45° in the traditional circular tube structure to 60°, which reduces the pressure per unit area of ​​the deck by more than 35% and reduces the overall cost of DSF by more than 60%. It can be customized and modified according to different upper block column foot point structure types, reducing steel consumption and carbon emissions. The strength of secondary welding is guaranteed through standardized cutting-repair process. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1-3 As shown, this utility model provides a modular adjustable marine large-scale modular transport support frame system, including a top support frame 1, multiple top load-bearing beams 7 installed inside the top support frame 1, upper modular column base points 8 installed on the outer wall of each top load-bearing beam 7, multiple intermediate support frames 2 installed at the bottom end of the top support frame 1, and bottom longitudinal load-bearing beams 6 fixed together on the outer side of each intermediate support frame 2 located below the top support frame 1, connecting blocks 5 installed at the opposite ends of the intermediate support frames 2 and the top support frame 1, and internal diagonal braces 4 installed between two connecting blocks 5.

[0017] The overall effect of Embodiment 1 is that the design of multiple top load-bearing beams 7 can, on the one hand, distribute the supporting force, and on the other hand, each top load-bearing beam 7 can be cut and replaced at any time. All components used are standardized steel components with cutting guide grooves and repair bevels, realizing the controllable disassembly and repair of the welded structure. The innovative four-step repair process of "cutting-inspection-welding-corrosion protection" ensures a strength retention rate of ≥95% after repair by precisely controlling the cutting temperature (≤200℃) and welding parameters (150℃ preheating + narrow gap welding). This solution breaks through the limitation of traditional welded structures being used only once, achieving at least 3 cycles of reuse. At the same time, the graded force transmission design greatly improves the uniformity of load distribution and reduces the peak stress on the deck or dock. The modular unit structure, reversible connection interface, special repair process and performance index requirements form a complete protection chain from product to method. By establishing technical barriers through standardized design parameters (such as 30° repair bevel, 50mm transition zone, etc.), it provides an innovative solution for the transportation of heavy equipment at sea that is both economical and reliable.

[0018] Example 2, as Figure 1-3 As shown, each intermediate support frame 2 has a bottom mounting plate 3 fixed at its bottom end; there are multiple upper block column base points 8, and multiple upper block column base points 8 are installed on the outer side of each top support beam 7.

[0019] The overall effect of Embodiment 2 is that each component is formed into a unit. The supporting column unit is the main load-bearing component, which adopts a box-section welded structure and has internal stiffening ribs. The lateral stabilizing unit is an H-shaped steel beam that connects the column and transmits lateral loads. The diagonal bracing unit consists of internal diagonal braces 4 arranged diagonally to improve the anti-overturning capacity. The traditional integral welded DSF is decomposed into several standardized welding units, which are controlled to be cut and separated at preset positions. The cut surface is reserved with a repair bevel to support secondary welding and reassembly. Moreover, the surface of each component is coated with a multi-layer repairable anti-corrosion coating to ensure the anti-corrosion performance after cutting and repair. This device can dynamically adjust the number and position of support points according to the center of gravity distribution of different blocks through the flexible arrangement and combination of standardized units, so that the deck stress points are increased from the traditional 4-6 fixed points to 8-12 adjustable support points. Each modular unit adopts a composite structure of box beams and internal diagonal braces 4. Through the stress gradient transmission design inside the welding unit, the concentrated load is gradually dispersed. Actual test data shows that the load diffusion angle has been increased from 45° in the traditional circular tube structure to 60°, which reduces the pressure per unit area of ​​the deck by more than 35% and reduces the overall cost of DSF by more than 60%. It can be customized according to different upper block column foot point 8 structural types, reducing steel consumption and carbon emissions, and ensuring the strength of secondary welding through standardized cutting-repair process.

[0020] Working Principle: When in use, this device forms individual units from its components. The supporting column unit is the main load-bearing component, using a box-section welded structure with internal stiffening ribs. The lateral stabilizing unit is an H-shaped steel beam connecting the columns, transmitting lateral loads. The diagonal bracing unit consists of four internal diagonal braces arranged diagonally to improve overturning resistance. The traditional integrally welded DSF is decomposed into several standardized welding units, which are then controllably cut and separated at preset positions. The cut surfaces are pre-reserved for repair bevels, supporting secondary welding and reassembly. Furthermore, each component surface is coated with a multi-layer repairable anti-corrosion coating to ensure corrosion resistance after cutting and repair. Through the flexible arrangement and combination of standardized units, the number and position of support points can be dynamically adjusted according to the center of gravity distribution of different blocks, increasing the deck stress points from the traditional 4-6 fixed points to 8-12 adjustable support points. Each modular unit uses a composite structure of box beams and internal diagonal braces, and through the stress gradient transfer design within the welding unit, concentrated loads are gradually dispersed. Actual test data shows that the load diffusion angle has been increased from 45° in the traditional circular tube structure to 60°, which reduces the pressure per unit area of ​​the deck by more than 35% and reduces the overall cost of DSF by more than 60%. It can be customized according to different upper block column foot point 8 structural types, reducing steel consumption and carbon emissions, and ensuring the strength of secondary welding through standardized cutting-repair process.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
