DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with specific embodiments and with reference to the drawings.

[0034] It should be noted that the technical terms or scientific terms used in the embodiments of the present application should be understood as the general meaning understood by those skilled in the art to which the embodiments of the present application belong, unless otherwise defined. The terms "first", "second", and similar terms used in the embodiments of the present application do not represent any order, quantity, or importance, but are only used to distinguish different components. The terms "include", "contain", and similar terms mean that the elements or objects before the terms cover the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right", and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0035] In some design processes of the hoisting beam, in order to adapt to different types of cargo specifications, the hoisting beam is designed as a multi-section structure to realize the function of adjustable length. The flange type sealing plates are used to connect these multi-section hoisting beams, and high-strength bolts are used for fastening. However, manual operation is required during each adjustment process, and after the adjustment is completed, the bolts also need to be treated with torque to ensure their fastening and safety. The torque treatment of the adjusted bolts requires professional skills and tools, which may be difficult for ordinary operators, resulting in complex adjustment operation and low efficiency. In addition, frequent adjustment and fastening of the bolts may also cause damage or loosening, thereby affecting the stability and safety of the hoisting beam.

[0036] Based on this, the present application provides a hoisting beam to solve the above technical problems, which can be referred to the following embodiments.

[0037] Referring to Figures 1 to 5 An embodiment of the present application provides a hoisting beam 100, which comprises a main body part 1 and a hoisting structure 2. The main body part 1 comprises two opposite mounting surfaces 101, and a plurality of hoisting structures 2 are arranged on each of the two mounting surfaces 101. The hoisting structure 2 comprises a rope winding part 21 and a blocking part 22, and the rope winding part 21 is arranged between the mounting surface 101 and the blocking part 22. At least in the length direction of the main body part 1, the size of the blocking part 22 is greater than the size of the rope winding part 21. The rope winding part 21 is used for connecting the hoisting rope, and the blocking part 22 is used for preventing the hoisting rope on the rope winding part 21 from slipping off.

[0038] The lifting beam 100 provided in this embodiment of the application, by setting the rope winding part 21 and the blocking part 22 on two opposite mounting surfaces 101, allows the sling (such as a wire rope) to be directly looped onto the rope winding part 21 during the lifting process, while the blocking part 22 prevents the sling from slipping outward. The sling can be connected to lifting equipment or goods, forming a basket-type lifting suspension, without the need for shackles to connect to the lifting beam 100. This connection method avoids complex bolt connections and adjustment operations; at the same time, the sling can be directly looped onto the rope winding part 21 without shackles, reducing wear and safety hazards caused by connecting parts, resulting in more even force distribution, improving the overall efficiency, economy, and safety of the operation, and ensuring the stability of the lifting process.

[0039] Specifically, when lifting goods, two symmetrically sized lifting structures 2 from among multiple lifting structures 2 can be selected based on the specific length of the goods to suspend the slings connected to the goods. Furthermore, the combined center of gravity of the goods and the lifting beam 100 can be calculated to determine the most suitable lifting structure 2 to be selected on the lifting beam, ensuring that the combined center of gravity is collinear with the lifting point. This guarantees a uniform distribution of force at each lifting point (where the lifting structure 2 is located) during the lifting process, ensuring stability and safety under high-intensity operating conditions.

[0040] In some embodiments, the main body 1 includes two side plates 11, which are spaced apart, and a mounting surface 101 is located on the side plates 11. Specifically, the mounting surface 101 is formed on the surfaces of the opposite sides of the two side plates 11.

[0041] Furthermore, the hoisting structure 2 includes a load-bearing shaft 20, which passes through two spaced-apart side plates 11. The portion of the load-bearing shaft 20 extending toward the opposite sides of the two side plates 11 forms a rope winding portion 21.

[0042] Furthermore, the blocking part 22 is a tubular structure, and the axis of the blocking part 22 is perpendicular to the axis of the support shaft 20. The length of the blocking part 22 is greater than the outer diameter of the support shaft 20 to form an anti-detachment structure.

[0043] The load-bearing shaft 20 is inserted into the two side plates 11 of the main body 1, which can transfer the force to the main body 1. In this way, it can be ensured that the hoisting structure 2 of the lifting beam 100 is mainly subjected to vertical force, reducing the oblique force conditions.

[0044] Furthermore, the cross-sectional shape of the load-bearing shaft 20 is circular, and the cross-sectional shape of the blocking part 22 is square.

[0045] Specifically, the load-bearing shaft 20 is a tubular fitting, specifically a seamless round tube. The blocking part 22 is a square tube. The square tube design of the blocking part 22 facilitates connection and fixation with the load-bearing shaft 20, and one side plane of the blocking part 22 is welded to the end of the load-bearing shaft 20. The round tube design of the load-bearing shaft 20 reduces wear on the wire rope on the rope winding part 21, helps extend the service life of the wire rope, reduces the frequency of maintenance and replacement, and provides higher reliability for lifting operations.

[0046] Of course, in addition to round tubes, the load-bearing shaft 20 can also be other closed structures enclosed by smooth curved surfaces.

[0047] Optionally, the load-bearing shaft 20 is welded to the side plate 11. Alternatively, after the load-bearing shaft 20 passes through the side plate 11, a locating pin is used to radially insert the load-bearing shaft 20 on the opposite sides of the two side plates 11. The locating pin engages with the corresponding side plate 11 to stop the load-bearing shaft 20, so that the load-bearing shaft 20 is detachably fixed on the side plate 11.

[0048] In some embodiments, the main body 1 includes a top plate 12 and a bottom plate 13, which are spaced apart from each other. The main body 1 is a box-shaped beam formed by the top plate 12, the bottom plate 13, and two side plates 11.

[0049] Specifically, the top plate 12, bottom plate 13, and two side plates 11 are connected to each other according to the corresponding assembly relationship and welding sequence, forming the overall structure of the box girder to meet the hoisting requirements. The box girder also has a good cooperation with the load-bearing shaft 20. The load-bearing shaft 20 is inserted into the two side plates 11 of the main body 1 to transfer the force to the box girder, ensuring the structural stability and load-bearing capacity of the hoisting beam, and ensuring the safety and reliability of the hoisting operation.

[0050] Optionally, the main body 1 includes lifting lugs 16, which are disposed on the top of the main body 1. Specifically, four lifting lugs 16 are symmetrically disposed on the upper side of the two side plates 11. The four lifting lugs 16 form two groups along the length of the main body 1, and the two lifting lugs 16 in each group are aligned in a direction perpendicular to the side plates 11. In use, slings can be connected to the lifting lugs 16 to connect the lifting beam 100 to the lifting equipment.

[0051] Furthermore, a box girder is formed by welding the top plate 12, the bottom plate 13, and the two side plates 11 together. Welded pipes 15 are installed at the corner welds of the box girder, extending along the length of the main body 1. The welded pipes 15, together with the side plates 11, top plate 12, bottom plate 13, and other related components, constitute a stable overall structure. By welding the pipes 15, the connection strength and stability of the entire lifting beam structure are enhanced, ensuring that it can withstand the corresponding loads during hoisting.

[0052] Optionally, the main body 1 includes multiple partitions 17, which are perpendicular to the side plates 11, and are spaced apart along the length inside the box girder. The partitions 17 serve to enhance the structural stability.

[0053] Optionally, the main body 1 includes sealing plates 18 at both ends. The sealing plates 18 enclose the local structure of the box girder, forming a relatively enclosed space together with other components such as side plates, partitions, bottom plates, and top plates, allowing forces to be better transmitted within the structure. At the same time, they strengthen the connection between the components, ensuring that the entire box girder structure can withstand the corresponding loads during hoisting, thus guaranteeing the safety and stability of the hoisting operation.

[0054] For example, the manufacturing process of the main body 1 includes the following steps: first, after the panels are assembled, two side plates 11 and the load-bearing shaft 20 are assembled and welded for flaw detection; then, the partition 17 is assembled and welded; then, the side plates 11 are welded to the top plate 12; the side plates 11 are welded to the bottom plate 13; the sealing plate 18 is welded to the sub-components; the blocking part 22 is welded to the load-bearing shaft 20; and finally, the lifting lug plate 16 and the welded pipe 15 are welded to the sub-components.

[0055] In some embodiments, multiple hoisting structures 2 are staggered on the mounting surface 101 along a first direction (X direction in the figure) and a second direction (Z direction in the figure), where the first direction is the length direction of the mounting surface 101 and the second direction is the width direction of the mounting surface 101.

[0056] Specifically, taking a horizontally placed lifting beam 100 as an example, the first direction can correspond to the left-right direction, and the second direction can correspond to the up-down direction. At least two rows of lifting structures 2 are installed on the same mounting surface 101, with the upper and lower rows staggered left and right. This avoids interference when both rows of lifting structures 2 are connected to slings.

[0057] In some embodiments, the lifting structure 2 is divided into a first type of lifting structure 201 and a second type of lifting structure 202. The first type of lifting structure 201 is used to connect with the lifting equipment via slings, and the second type of lifting structure 202 is used to connect with the cargo via slings.

[0058] Furthermore, the blocking part 22 in the first type of lifting structure 201 is inclined. The blocking part 22 in the second type of lifting structure 202 is horizontal.

[0059] The lifting beam 100 of this application can be used to lift marine engineering modules with a length between 3.3 meters and 14.24 meters and a weight not exceeding 474 tons. For example, the lifting beam 100 is equipped with twenty-two sets of lifting structures 2 to facilitate connection between slings and lifting equipment or cargo. Each set of lifting structures 2 is arranged symmetrically about a first plane, which is parallel to the mounting surface 101 and located in the middle of the two side plates 11. All the lifting structures 2 are arranged symmetrically left and right in the first direction. In use, an appropriate lifting structure 2 can be selected according to the specific length of the cargo, and then the slings can be used to connect it to the marine engineering module to ensure stability during the lifting process.

[0060] The lifting beam 100 of this application significantly improves the actual lifting capacity of the crane. The unique sling suspension method not only effectively reduces wear on the wire rope but also ensures uniform stress distribution at each lifting point during hoisting, thereby optimizing the stress state of the wire rope and greatly extending its service life. Simultaneously, the reasonable force transmission of the load-bearing shaft 20 helps determine the position of the lifting beam and select suitable lifting points, ensuring that the combined center of gravity is collinear with the lifting points, reducing the risk of hoisting accidents caused by eccentricity, and providing stronger safety assurance.

[0061] Reference Figures 6 to 9 As shown, another embodiment of this application provides a lifting device, which includes the lifting beam 100 in the above embodiment, and also includes a plurality of slings 3, which are wound around the rope portion 21 of the lifting beam 100.

[0062] Furthermore, the sling 3 includes a first type of sling 301 and a second type of sling 302. The first type of sling 301 is connected between the lifting equipment 4 and the corresponding first type of lifting structure 201, and the second type of sling 302 is connected between the second type of lifting structure 202 and the cargo.

[0063] For example, depending on the height, the second type of hoisting structure 202 has at least two rows.

[0064] Optionally, the first type of sling 301 and the second type of sling 302 are respectively connected to the hoisting structure 2 at the same height. That is, one end of the second type of sling 302 is suspended on the hoisting structure 2 at the same height as the first type of hoisting structure 201 in the second type of hoisting structure 202.

[0065] Optionally, the first type of sling 301 and the second type of sling 302 are respectively connected to the hoisting structure 2 at different heights. That is, one end of the second type of sling 302 is suspended on the hoisting structure 2 at a different height from the first type of hoisting structure 201 in the second type of hoisting structure 202.

[0066] Optionally, the two ends of the second type of sling 302 are suspended on the lifting structure 2 at different heights, and the cargo is connected to the middle part of the second type of sling 302.

[0067] In the lifting device provided in this embodiment, the lifting beam 100 has a rope winding part 21 and a blocking part 22 arranged on two opposite mounting surfaces 101. During the lifting process, the sling (such as a wire rope) can be directly looped onto the rope winding part 21, and the blocking part 22 prevents the sling from slipping outward. The sling can connect to the lifting equipment or goods, forming a basket-type lifting suspension. This connection method avoids complex bolt connections and adjustment operations. At the same time, the sling can be directly looped onto the rope winding part 21, reducing wear and safety hazards caused by connecting parts, resulting in more even force distribution, improving the overall efficiency, economy, and safety of the operation, and ensuring the stability of the lifting process.
