Description

Technical Field

[0001] This utility model relates to the field of marine lifting technology, specifically to a lifting frame for heavy marine components. Background Technology

[0002] During the construction and maintenance of large offshore structures such as offshore oil platforms and wind power platforms, it is often necessary to lift extremely heavy components (such as large steel structural components and equipment modules). These components are often extremely heavy, vary in size, and have very different lifting point locations on different work platforms.

[0003] Currently, the use of lifting rigs lacks segmented beam structures. Most existing lifting rigs used in offshore lifting are integral frame structures with fixed frame beam lengths and stress point positions. However, the structural dimensions and component installation positions of different offshore platforms vary significantly. When lifting heavy components from different platforms, fixed-size lifting rigs often cannot meet the lifting requirements. Either the frame beam length is insufficient, leading to inaccurate component alignment, or the stress point does not match the component's center of gravity, causing instability during lifting and even posing safety hazards. Therefore, a lifting rig for heavy offshore components is proposed, which allows the frame beams to be designed as segmented beam structures. By adding or removing segments, the frame beam length and stress points can be changed, enabling efficient and stable lifting of heavy components from different platforms. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a lifting frame for heavy-duty marine components, which allows for the efficient and stable lifting of heavy-duty components on different platforms by adding or removing segments to change the length of the frame beam and the stress points, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a lifting frame for marine heavy components, including a lifting platform, a frame beam assembly and an upper beam assembly. The top of the lifting platform is provided with the frame beam assembly, and the top of the frame beam assembly is provided with the upper beam assembly. The frame beam assembly includes a fixed seat, a short section, and a long section. The short section and the long section are connected to the fixed seat by welding. An extension section is welded to one side of the long section. An adjustment section is provided between the short section and the long section. The ends of the short section, the long section, the extension section, and the adjustment section are all welded with splicing perforated plates.

[0006] By adopting the above technical solution, the installation position, i.e. the stress point, of the hoisting lugs can be adjusted according to the size and center of gravity of the heavy components on different platforms.

[0007] Specifically, the upper beam assembly includes a beam body, a third lifting lug is welded to the top of the beam body and penetrates through the beam body, and a fourth lifting lug is welded to the bottom of the third lifting lug.

[0008] Specifically, a first lifting lug is welded to the top of the fixed seat, and a second lifting lug is provided at the bottom of the fixed seat, short section, long section, extension section and adjusting section. Reinforcing ribs are welded at equal intervals between the splicing plate and the short section, long section, extension section and adjusting section.

[0009] Specifically, a second splicing plate is welded to one end of the beam, and a second reinforcing rib is welded at equal intervals between the second splicing plate and the beam.

[0010] Specifically, a ring-eye sling is provided between the hoisting platform and the frame beam assembly, a ring-shaped sling is provided between the frame beam assembly and the upper beam assembly, a hook is provided on the top of the upper beam assembly, and a second ring-shaped sling is provided between the upper beam assembly and the hook.

[0011] The beneficial effects of this utility model are: The lifting frame for heavy-duty offshore components described in this utility model incorporates a segmented beam structure through fixed seats, short sections, long sections, extension sections, adjusting sections, and splicing perforated plates. By adding or removing segment units, the overall length of the frame beam can be flexibly adjusted. The installation position and stress point of the lifting lugs can be adjusted according to the size and center of gravity of heavy-duty components on different platforms, making the lifting frame suitable for lifting operations on various specifications of offshore platforms. This greatly improves the versatility of the lifting frame. Furthermore, the segment units can be disassembled for transportation, reducing transportation size and lowering transportation difficulty and cost. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] To facilitate the efficient and stable hoisting of heavy components on different platforms by adding or removing segments to change the length and stress points of the frame beams, thereby improving usability, such as... Figure 1-3 As shown, the lifting frame for heavy marine components of this utility model includes a lifting platform 1, a frame beam assembly 2, and an upper beam assembly 3. The frame beam assembly 2 is provided on the top of the lifting platform 1, and the upper beam assembly 3 is provided on the top of the frame beam assembly 2. The frame beam assembly 2 includes a fixed base 201, a short section 202, and a long section 203. The short section 202 and the long section 203 are connected to the fixed base 201 by welding. An extension section 204 is welded to one side of the long section 203. An adjustment section 205 is provided between the short section 202 and the long section 203. A splicing perforated plate 206 is welded to the ends of the short section 202, the long section 203, the extension section 204, and the adjustment section 205.

[0016] During use, operators can select an appropriate number of short sections 202, long sections 203, extension sections 204, and adjusting sections 205 based on the size and weight of the heavy components to be lifted and the actual spacing of the lifting points on the offshore platform. Each section is aligned and connected using high-strength bolts or welding through the splicing plate 206 at its end, thereby assembling a complete frame beam of the required length. By adjusting the combination of sections, not only can the overall length of the beam be changed, but the distribution position of the second lifting lug 208 at the bottom can also be precisely adjusted to match the center of gravity of the component, ensuring the stability and safety of the lifting process.

[0017] The hoisting platform 1 includes lifting lugs.

[0018] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes the following: the upper beam assembly 3 includes a beam body 301, a third lifting lug 302 is welded to the top of the beam body 301 and the third lifting lug 302 penetrates the beam body 301, and a fourth lifting lug 303 is welded to the bottom of the third lifting lug 302.

[0019] In use, the third lifting lug 302 is used to connect to the hook 6 or the second ring sling 7 from the crane and is the main force transmission point. The fourth lifting lug 303 is used to connect to the frame beam assembly 2, further increasing the stability and versatility of the lifting system.

[0020] For example, such as Figure 2As shown, the present invention also includes a first lifting lug 207 welded to the top of the fixed base 201, a second lifting lug 208 provided at the bottom of the fixed base 201, the short section 202, the long section 203, the extension section 204 and the adjusting section 205, and reinforcing ribs 209 welded equidistantly between the splicing plate 206 and the short section 202, the long section 203, the extension section 204 and the adjusting section 205.

[0021] In use, the first lifting lug 207 is used to connect with the upper beam assembly 3, and the second lifting lug 208 is used to connect with the lower hoisting platform 1. Their positions can be flexibly selected according to the lifting points on the components. The reinforcing rib 209 can significantly enhance the connection strength between the splicing perforated plate 206 and each segment of the main body, prevent deformation or tearing under heavy load, and ensure the structural integrity at the nodes. The first lifting lug 207, the second lifting lug 208, the third lifting lug 302 and the fourth lifting lug 303 all include a baffle, a pin, a pin retainer and a handle.

[0022] For example, such as Figure 3 , 4 As shown, the present invention also includes a second splicing plate 304 welded to one end of the beam 301, and a second reinforcing rib 305 welded at equal intervals between the second splicing plate 304 and the beam 301.

[0023] In use, the second splicing perforated plate 304 enables the upper beam assembly 3 itself to have modular expansion capability. When a longer upper beam is needed, another beam 301 can be fixedly connected by bolts through the perforated plate. The function of the second reinforcing rib 305 is also to ensure the strength and rigidity of the extended connection node.

[0024] For example, such as Figure 1 As shown, the present invention also includes a ring-eye sling 4 between the hoisting platform 1 and the frame beam assembly 2, an annular sling 5 between the frame beam assembly 2 and the upper beam assembly 3, a hook 6 on the top of the upper beam assembly 3, and a second annular sling 7 between the upper beam assembly 3 and the hook 6.

[0025] When in use, the eyelet sling 4 and the ring sling 5 together form a flexible force transmission system, which can adapt well to different angles and small displacements generated during the hoisting process and reduce the bending moment on the rigid structure.

[0026] In use, this utility model first calculates and determines the required total length of the frame beam and the distribution of lifting points according to the needs of the lifting task. Then, it selects appropriate fixed seats 201, short sections 202, long sections 203, extension sections 204 and adjusting sections 205, and uses splicing plate 206 and high-strength bolts or welding to firmly assemble them into one piece. Next, the annular lifting strap 5 is folded and installed between the upper beam assembly 3 and 2 through the first lifting lug 207 and the fourth lifting lug 303. Subsequently, the annular lifting strap 4 is connected between the lifting platform 1 and the frame beam assembly 2 through the lifting lug 1 and the second lifting lug 208. Finally, the crane hook 6 is connected to the third lifting lug 302 of the upper beam assembly 3 through the second annular lifting strap 7. After a comprehensive safety inspection, it can be lifted smoothly. After the operation is completed, the entire lifting frame can be easily disassembled into modular units for easy transportation and storage.
