Description

Technical Field

[0001] This utility model relates to the field of offshore wind power equipment hoisting, specifically an offshore wind power equipment transportation and hoisting device. Background Technology

[0002] Offshore wind power equipment is mainly used for the construction and operation of wind farms at sea, converting offshore wind energy into electrical energy to provide clean power to the grid. It also ensures the stable operation and efficient power generation of wind farms. The development trend of offshore wind power equipment is towards larger scale. With the increase in single-unit capacity, the power of wind turbine units, rotor diameter, tower height and capacity factor of large wind turbines are increased, resulting in increased annual power generation. At the same time, it reduces the investment in foundations, cables, installation and operation, and lowers electricity costs.

[0003] Existing offshore wind power equipment relies on lifting equipment for transportation and installation. This equipment includes various tools and devices used to lift large components such as wind turbines and towers from transport ships to designated locations during offshore wind farm construction, ensuring a smooth installation process. However, existing offshore wind power equipment transportation and lifting equipment still has the following problems in use:

[0004] Existing transport and hoisting equipment requires first attaching a hoisting rope to the offshore wind turbine, and then using a hook to lift the rope. Because offshore wind turbines are prone to swaying at high altitudes, the hoisting rope can easily shift on the hook, causing the hook to come into contact with the wind turbine. Furthermore, when the wind turbine reaches its destination and is supported, it no longer bears the load on the hoisting rope, causing the rope to slacken and the hook to collide with the surface of the wind turbine, resulting in surface damage. Therefore, it is necessary to develop a new transport and hoisting device for offshore wind turbines for use in the current offshore wind turbine lifting field. Utility Model Content

[0005] To address the shortcomings of existing technologies, current offshore wind turbines are prone to swaying when hoisted at high altitudes, causing the hoisting ropes to shift on the hooks and come into contact with the wind turbines. Furthermore, when the wind turbines are delivered to their destination and are supported, they no longer exert force on the hoisting ropes, leading to slack in the ropes and collisions between the hooks and the surface of the wind turbines, causing surface damage. This invention proposes a transport and hoisting device for offshore wind turbines.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a lifting device for transporting offshore wind power equipment, including a lifting machine and a hook. The hook is equipped with a lifting rope, one end of which is fixedly equipped with a hook, and the other end of which is fixedly equipped with a connecting ring. A connecting rope is fixedly equipped on the side of the hook, and one end of the connecting rope is fixedly equipped with an operating block. An operating cavity is provided inside the operating block, and a traction port is provided on the end face of the operating block. The traction port communicates with the operating cavity. Guide rods are symmetrically fixedly equipped on the inner wall of the operating cavity. The guide rods are located on both sides of the traction port, and sliding blocks are movably equipped on the two guide rods.

[0007] Preferably, each guide rod is equipped with a spring, and the two ends of the spring are fixedly assembled with the inner wall of the operating cavity and the sliding block, respectively.

[0008] Preferably, an adjusting rope is fixedly mounted on the sliding block, and the adjusting rope is movably assembled with the traction port. A positioning ring is fixedly mounted on one end of the adjusting rope.

[0009] Preferably, the connecting ring is engaged with the hook, and the positioning ring is engaged with the lifting hook.

[0010] Preferably, the hoist is equipped with multiple lifting lines, and assembly blocks are fixedly mounted on the bottom of the multiple lifting lines.

[0011] Preferably, the bottom of the assembly block is fixedly assembled with the hook.

[0012] The advantages of this utility model are:

[0013] This invention involves installing a lifting rope and a hook, allowing the rope to be fitted onto the offshore wind turbine. A connecting ring is engaged with the hook, and a positioning ring is engaged with the hook. When the hoisting machine is started, the lifting line moves the hook on the assembly block up and down, facilitating the lifting of the offshore wind turbine. Under the weight of the offshore wind turbine, the adjusting rope moves the sliding block on the guide rod, causing the elastic spring to contract. When the offshore wind turbine swings during high-altitude transport, the hook is controlled by the positioning ring, preventing the lifting rope from moving extensively on the hook and preventing the hook from contacting the offshore wind turbine. Simultaneously, when the offshore wind turbine reaches its destination, it is supported, and without the influence of its own weight, the elastic spring causes the hook to move towards the hook, preventing collision and improving the protection of the offshore wind turbine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0026] This application discloses a transport and hoisting device for offshore wind power equipment. (Refer to...) Figure 1 and Figure 3 as well as Figure 4A lifting and hoisting device for transporting offshore wind power equipment includes a hoisting machine 10 and a hook 13. A hoisting rope 20 is mounted on the hook 13. A hook 21 is fixedly mounted at one end of the hoisting rope 20, and a connecting ring 22 is fixedly mounted at the other end of the hoisting rope 20. The connecting ring 22 engages with the hook 21. A connecting rope 30 is fixedly mounted on the side of the hook 21. An operating block 31 is fixedly mounted at one end of the connecting rope 30. An operating cavity 33 is provided inside the operating block 31. A traction port 40 communicating with the operating cavity 33 is provided on the end face of the operating block 31. Guide rods 41 are symmetrically fixedly mounted on the inner wall of the operating cavity 33, located on both sides of the traction port 40. Sliding blocks 42 are movably mounted on the two guide rods 41. A spring spring 43 is fixedly mounted between the inner wall of the operating cavity 33 and the sliding blocks 42. The guide rods 41 are all mounted inside the spring spring 43. An adjusting rope 32 that moves within the traction port 40 is fixedly mounted on the sliding block 42. One end of the adjusting rope 32... A positioning ring 23 is fixedly mounted at the end, and the positioning ring 23 is engaged with the hook 13. The lifting rope 20 is installed with the hook 13 so that the lifting rope 20 is looped onto the offshore wind power equipment. The connecting ring 22 is engaged with the hook 21, and the positioning ring 23 is engaged with the hook 13. During the hoisting operation, under the gravity of the offshore wind power equipment, the adjusting rope 32 drives the sliding block 42 to move on the guide rod 41, and the elastic spring 43 contracts. When the offshore wind power equipment swings during high-altitude hoisting, the hook 21 is affected by the positioning ring 23, and the lifting rope 20 cannot move a wide range on the hook 13. The hook 21 cannot contact the offshore wind power equipment. At the same time, when the offshore wind power equipment is delivered to the destination, the offshore wind power equipment is supported. Without the influence of the gravity of the offshore wind power equipment, under the elastic force of the elastic spring 43, the hook 21 moves towards the hook 13 to avoid collision between the hook 21 and the offshore wind power equipment.

[0027] Reference Figure 1 and Figure 2 The hoisting machine 10 is equipped with multiple lifting lines 11. The bottom of the multiple lifting lines 11 is fixedly equipped with assembly blocks 12. The bottom of the assembly blocks 12 is fixedly assembled with the hooks 13. When the hoisting machine 10 is started, the lifting lines 11 drive the hooks 13 on the assembly blocks 12 to rise and fall, so that the hooks 13 can lift and transport offshore wind power equipment.

[0028] Working principle: The lifting rope 20 is installed on the hook 13, allowing it to be looped onto the offshore wind turbine. The connecting ring 22 is engaged with the hook 21, and the positioning ring 23 is engaged with the hook 13. The hoisting machine 10 is started, causing the lifting line 11 to move the hook 13 on the assembly block 12, facilitating the lifting of the offshore wind turbine. Under the weight of the offshore wind turbine, the adjusting rope 32 moves the sliding block 42 on the guide rod 41, causing the spring spring 43 to contract. When the wind turbine swings during high-altitude hoisting, the hook 21 is supported by the positioning ring 23, preventing the hoisting rope 20 from moving extensively on the hook 13. The hook 21 also cannot contact the offshore wind turbine. Simultaneously, when the offshore wind turbine is delivered to its destination, it is supported and free from the influence of gravity. Under the elastic force of the spring 43, the hook 21 moves towards the hook 13, preventing collision between the hook 21 and the offshore wind turbine and improving its protection.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
