Description

Technical Field

[0001] The invention relates to the technical field of lifting ears, in particular to a cylinder turning lifting ear. Background Art

[0002] The rotor sail barrel is a rotatable lightweight cylinder, usually made of high-strength, corrosion-resistant materials to ensure its long-term stable operation in the harsh offshore environment. It constitutes the main part of the rotor sail and generates power through rotation.

[0003] The rotor sail cylinder uses the "Magnus effect" to propel the ship forward. When the air flows through the rotating cylinder, low pressure is generated on one side of the cylinder and high pressure is generated on the other side, thereby generating a lateral force perpendicular to the direction of the airflow. When this force is projected to the direction of the ship's advance, it becomes the thrust that propels the ship forward. By adjusting the speed and rotation direction of the rotor sail cylinder, the magnitude and direction of the force can be adjusted, thereby providing the required auxiliary thrust for the ship.

[0004] The rotor sail cylinder is usually transported horizontally to the assembly site on a flatbed truck during installation. The cylinder is then turned from a horizontal state to a vertical state and then lifted vertically and inserted into the base for assembly.

[0005] The existing turning lugs are generally welded directly to the outer wall of the cylinder, and after the lifting is completed, the lugs need to be removed by thermal cutting, which damages the paint and may interfere with the electrical structures such as cables in the tower due to careless operation, thereby adding a lot of unnecessary troubles and potential risks. For this purpose, a cylinder turning lug is provided. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a cylinder turning over lifting eye, comprising: a bottom plate 1 and a main connecting plate 2. The bottom plate 1 is the basis of the entire lifting eye structure, and it provides a plane connected to the rotor sail cylinder. A main connecting plate 2 is fixed on one side of the bottom plate 1. The main connecting plate 2 is a key component connecting the bottom plate 1 and the first lifting eye plate 3. It is located on one side of the bottom plate 1 and is fixed to the bottom plate 1 by welding or other connection methods. The main connecting plate 2 not only provides the stability of the lifting eye structure, but also ensures the overall strength of the lifting eye during the lifting process.

[0023] A first lifting lug plate 3 is provided on one side of the main connecting plate 2. The first lifting lug plate 3 is the main force-bearing component during the lifting process. It is usually designed as a plate-like structure with a lifting hole for connecting lifting ropes or lifting equipment. A plurality of through holes are provided in the base plate 1. A main connecting bolt 13 is provided on the through hole located in the middle of the base plate 1. A secondary connecting bolt 12 is provided on the through holes located on both sides of the base plate 1. The plurality of through holes provided on the base plate 1 are used to install the main connecting bolt 13 and the secondary connecting bolt 12. These bolts firmly fix the lifting lug to the rotor sail barrel. The through holes provided on the base plate 1 are used to install the main connecting bolt 13 and the secondary connecting bolt 12. The design of these through holes takes into account the diameter and spacing of the bolts to ensure that the bolts can be firmly fixed to the rotor sail barrel.

[0024] A first clamping plate 10 is provided on one side of the base plate 1, and a second clamping plate 11 is provided on the other side of the first clamping plate 10. The lifting lug is fixed to the cylinder by a main connecting bolt 13 and a secondary connecting bolt 12. The cylinder is located between the first clamping plate 10 and the second clamping plate 11. The first clamping plate 10 and the second clamping plate 11 are used to clamp the rotor sail cylinder to ensure the stability of the lifting lug during the lifting process. They are respectively located on both sides of the base plate 1 and are fixed to the base plate 1 by bolts or other connection methods. The design of the first clamping plate 10 and the second clamping plate 11 takes into account the shape and size of the rotor sail cylinder to ensure a good fit and clamping effect. During the lifting process, they can prevent the shaking and displacement of the rotor sail cylinder and improve the safety and stability of the lifting.

[0025] The first reinforcing plate 5, the second reinforcing plate 6 and the third reinforcing plate 8 are provided on both sides of the main connecting plate 2. The first reinforcing plate 5, the second reinforcing plate 6 and the third reinforcing plate 8 are used to enhance the overall strength and stability of the lifting lug structure. They are respectively located on both sides of the main connecting plate 2 and near the first lifting lug plate 3, and are fixed to the main connecting plate 2 and the bottom plate 1 by welding or other connection methods. The design of these reinforcing plates takes into account the stress conditions of the lifting lug and the load distribution during the lifting process to ensure that the lifting lug will not be deformed or damaged when subjected to heavy loads. By adding reinforcing plates, the load-bearing capacity and service life of the lifting lug are significantly improved.

[0026] The first lug plate 3 is provided with a drum 4, which is rotatably connected to the first lug plate 3, and the two ends of the drum 4 are in an outward-expanding trumpet shape. The drum 4 can be connected to the hoisting wire rope. The rotation of the drum 4 and the smooth inner wall of the drum 4 itself and the lubricating oil can reduce the wear between the hoisting wire rope and the lug, avoid the severe wear of the wire rope and the lifting hole of the lug when the rotor sail cylinder is turned from horizontal to vertical, and improve the durability of the lug. In addition, the drum 4 can be replaced, which further extends the service life of the entire lug; the two ends of the drum 4 are in an outward-expanding trumpet shape design, which not only facilitates the smooth access and output of the hoisting wire rope, but also can disperse the pressure of the wire rope on the drum to a certain extent, reducing wear. The design of the drum 4 also takes into account its replaceability. During long-term use, although the inner wall of the drum 4 has been specially treated and lubricated, it may still gradually lose its smoothness due to wear. At this time, the user can replace the worn drum 4 through simple disassembly and replacement operations, thereby further extending the service life of the entire lug. This replaceable design not only improves the maintenance convenience of the lifting lugs, but also reduces the maintenance cost for users.

[0027] A first reinforcing connecting plate 7 is provided between the first reinforcing plate 5 and the second reinforcing plate 6, and a second reinforcing connecting plate 9 is provided between the second reinforcing plate 6 and the third reinforcing plate 8. The first reinforcing connecting plate 7 is located between the first reinforcing plate 5 and the second reinforcing plate 6, and it plays the role of connecting and reinforcing the two reinforcing plates. Through welding or other reliable connection methods, the first reinforcing connecting plate 7 firmly connects the first reinforcing plate 5 and the second reinforcing plate 6 together to form a more stable triangular support structure. This design not only improves the anti-deformation ability of the lifting ear when bearing heavy loads, but also effectively disperses the stress generated during the lifting process and reduces the force concentration phenomenon of a single component. The function of the second reinforcing connecting plate 9 is similar to that of the first reinforcing connecting plate 7. The second reinforcing connecting plate 9 also plays the role of connection and reinforcement, but it connects the second reinforcing plate 6 and the third reinforcing plate 8. With the addition of the second reinforcing connecting plate 9, the overall strength of the lifting ear structure is further improved. At the same time, the second reinforcing connecting plate 9 also optimizes the force distribution of the lifting ear, so that the lifting ear can bear the load more stably during the lifting process, reducing the risk of structural damage caused by uneven force.

[0028] The outer wall profile of one side of the first splint 10 matches the outer wall profile of the cylinder, and the outer wall profile of one side of the second splint 11 matches the inner wall profile of the cylinder. The outer wall profiles of one side of the first splint 10 and the second splint 11 match the inner and outer contours of the cylinder. This design ensures that the first splint 10 and the second splint 11 can fit tightly on the cylinder, reducing shaking and displacement during the lifting process. Through precise profile matching, the first splint 10 and the second splint 11 can provide sufficient support force to ensure that the lifting lug will not fall off or be damaged when bearing heavy loads.

[0029] An M-shaped elastic sheet 14 is provided on one side of the second clamping plate 11. A through hole is provided in the M-shaped elastic sheet 14 on the outside of the main connecting bolt 13. The nut of the main connecting bolt 13 abuts against one side of the M-shaped elastic sheet 14. When the main connecting bolt 13 is tightened, its nut abuts against one side of the M-shaped elastic sheet 14. Since the M-shaped elastic sheet 14 has good elasticity, it can generate a certain pre-tightening force under the action of the nut, thereby effectively locking the main connecting bolt 13 and preventing it from loosening during vibration or long-term use. This design not only improves the stability of the lifting ear, but also reduces the safety hazards caused by loose bolts.

[0030] The M-shaped elastic sheet 14 is provided with connecting edges at both ends, and screws 15 are provided between the connecting edges and the second clamping plate 11. The M-shaped elastic sheet 14 is provided with connecting edges at both ends. The main purpose of this design is to facilitate the M-shaped elastic sheet 14 to be firmly connected to the second clamping plate 11. The existence of the connecting edges enables the M-shaped elastic sheet 14 to be accurately positioned during the installation process, and forms a good contact surface with the second clamping plate 11, which provides convenience for the subsequent fixation with screws. The screws 15 serve as connecting parts to tightly fix the M-shaped elastic sheet 14 to the second clamping plate 11. By tightening the screws 15, sufficient pre-tightening force can be generated between the M-shaped elastic sheet 14 and the second clamping plate 11, thereby ensuring that the M-shaped elastic sheet 14 will not loosen or shift due to vibration or load changes during the lifting process.

[0031] An elastic rubber sleeve 17 is provided on the outer wall of the main connecting bolt 13, and a gasket 16 is provided at one end of the elastic rubber sleeve 17. One side of the gasket 16 abuts against the second clamping plate 11, and one end of the elastic rubber sleeve 17 abuts against the M-shaped elastic sheet 14. The elastic rubber sleeve 17, with its unique elasticity and flexibility, plays a role in preventing loosening between the main connecting bolt 13 and the nut.

[0042] A second eye plate 18 is provided on one side of the main connection plate 2, and a roller 4 is also rotatably provided in the second eye plate 18; a lifting ring 19 is provided in the roller 4 of the second eye plate 18 and the first eye plate 3, and a steel wire rope 20 is provided between the two lifting rings 19. The first eye plate 3 is used as the starting force point of the lifting system, and the first eye plate 3 is connected to the steel wire rope 20 through the roller 4 and the lifting ring 19 inside it. During the lifting process, the first eye plate 3 first bears the weight of the rotor sail cylinder and guides it to gradually turn from a horizontal state to a vertical state.

[0043] The second eye plate 18 is located on one side of the main connecting plate 2. Its structure is similar to that of the first eye plate 3, and is also provided with a roller 4 and a lifting ring 19. When the rotor sail cylinder is flipped to a nearly vertical state, the second eye plate 18 begins to be gradually stressed, and bears the weight of the rotor sail cylinder together with the first eye plate 3.

[0044] The first lug plate 3 and the second lug plate 18 are arranged on the same plane and at 90 degrees. The first lug plate 3 and the second lug plate 18 are arranged on the same plane and at 90 degrees. This design not only optimizes the spatial layout of the lifting system, but also realizes the reasonable distribution of the force on the lugs. During the lifting process, as the rotor sail cylinder flips, the first lug plate 3 is stressed first, and then as the flip angle increases, the second lug plate 18 begins to be gradually stressed. This alternating force method not only ensures the stability of the lifting process, but also avoids fatigue damage caused by a single lug plate bearing heavy loads for a long time.

[0045] When the cylinder turning over lifting lugs are used, the rotor sail cylinder has a roller connection hole, and the entire lifting lug is fixed to the two ends of the rotor sail cylinder through the main connecting bolts 13 and the auxiliary connecting bolts 12. When hoisting, the rotor sail cylinder can be turned over and hoisted from a horizontal state to a vertical state by lifting the lifting lug at one end, which is convenient for the subsequent installation and fixation of the rotor sail cylinder. At the same time, the bolt connection avoids the influence of welding and thermal cutting after hoisting on the paint; and the bolt connection can be reused, saving the production of the lifting lugs; In addition, during hoisting, the drum 4 can be connected to the hoisting wire rope. The rotation of the drum 4 and the smooth inner wall of the drum 4 and the application of lubricating oil can reduce the wear between the hoisting wire rope and the lifting lug, and avoid severe wear of the wire rope and the lifting hole of the lifting lug when the rotor sail cylinder is turned from horizontal to vertical, thereby improving the durability of the lifting lug. In addition, the drum 4 can be replaced, further extending the service life of the entire lifting lug. Moreover, when the lifting lug is in use, through the 90-degree setting of the first lifting lug plate 3 and the second lifting lug plate 18, when the rotor sail barrel is turned from horizontal to vertical during lifting, the first lifting lug plate 3 is first subjected to force, then the first lifting lug plate 3 and the second lifting lug plate 18, and finally the second lifting lug plate 18 is subjected to force. Through the alternation and sharing of force between the first lifting lug plate 3 and the second lifting lug plate 18, it is possible to ensure that the load requirements are met while improving the service life of the lifting lug.

[0046] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
