Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a steel structure transportation device for offshore wind turbine foundation construction. Background Technology

[0002] Amid the global push for clean energy transition, offshore wind power, with its enormous energy potential, has become a key area for sustainable energy development. Offshore wind turbine foundation construction is a crucial step in offshore wind power project construction, and the safety, stability, and precision of steel structure transportation, as the core component of the offshore wind turbine foundation, directly affect the success or failure of the entire project. The marine environment is extremely complex, with strong winds, giant waves, tides, and the corrosive effects of seawater posing numerous severe challenges to steel structure transportation. Traditional transportation equipment has gradually revealed various shortcomings in the face of these complex conditions and can no longer meet the increasingly high standards required for steel structure transportation in modern offshore wind turbine foundation construction. Therefore, developing a steel structure transportation device for offshore wind turbine foundation construction with advanced clamping and buffering functions is of paramount practical significance for promoting the efficient development of the offshore wind power industry, reducing construction risks, and improving construction quality.

[0003] Currently, in the construction of offshore wind turbine foundations, the transportation of steel structures typically employs relatively conventional methods. The transport carriers are generally ordinary cargo ships or simply modified vessels, whose power systems are mostly based on traditional diesel engines. These engines drive the propeller by burning diesel fuel, generating thrust to propel the ship at sea. For securing the steel structures, simple rope binding or simple clamps are commonly used. Rope binding involves wrapping high-strength ropes around the steel structure, using the friction generated by tightening the ropes to fix the steel structure to the ship's deck. Simple clamps connect the steel structure to the deck through mechanical clamping. These fixing methods rely primarily on physical friction and mechanical fastening force to resist the forces exerted on the steel structure by the ship's swaying during navigation. When lifting the steel structure, cantilever cranes mounted on the ship are commonly used. A cantilever crane consists of a boom, a slewing mechanism, a hoisting mechanism, and a support structure. The hoisting mechanism drives the drum to rotate via a motor, winding and unwinding the wire rope. It uses pulley blocks to change the direction of force, thus lifting the steel structure. The slewing mechanism enables the boom to rotate around the central axis, allowing the steel structure to be transported to the designated location. The support structure provides the necessary stability for the entire crane during lifting operations.

[0004] Existing steel structure transport devices for offshore wind turbine foundation construction cannot guarantee the stable clamping of steel structures under complex sea conditions. When encountering large waves, the ship will sway violently. The existing fixing methods rely only on the friction of ropes or the fastening force of simple clamps. Most existing transport devices use simple passive cushioning materials and cannot actively adjust according to changes in actual sea conditions. Utility Model Content

[0026] Reference Figures 1-3 An embodiment of this utility model is provided: a steel structure transportation device for offshore wind turbine foundation construction, including a connecting steel plate seat 6, a clamping assembly provided below the connecting steel plate seat 6, and a buffer assembly provided inside the connecting steel plate seat 6;

[0027] The clamping assembly includes a movable plate 16, which moves along a slide under the push of a push roller 14, driving the connecting module 15 to ensure smooth and accurate movement. The push roller 14 is fixedly connected to the upper surface of the movable plate 16. The push roller 14 moves under the push of a cylinder 8, transmitting the thrust of the cylinder 8 to the movable plate 16; it is an intermediate link in power transmission. One end of the push roller 14 is fixedly connected to the output end of the cylinder 8. A clamping upper seat 7 is provided on the outer wall of the push roller 14.

A rotating roller 9 is rotatably connected to the inner wall of the clamping upper seat 7. A clamping arm 10 is fixedly connected to the outer wall of the rotating roller 9. The clamping arm 10 directly performs the action of clamping the object, moving under the drive of the rotating roller 12 to achieve the clamping of the object. A rotating roller 12 is rotatably connected to the inner wall of the arm 10. The rotation of the rotating roller 12 provides power for the movement of the clamping arm 10 and is the power source for the movement of the clamping arm 10. A connecting rod 13 is fixedly connected to the outer wall of the rotating roller 12. The connecting rod 13 connects the rotating roller 3 17 and the component rotating roller 12, transmitting motion and causing the component rotating roller 12 to rotate. The rotating roller 3 17 is rotatably connected to the inner wall of the connecting rod 13.

One end of the spring damper 19 is fixedly connected to the clamping upper seat 7. One end of a spring 23 is fixedly connected to the outer wall of the clamping upper seat 7. A guide post 22 is fixedly connected to the inner wall of the connecting steel plate seat 6. The guide post 22 provides precise guidance for the movement of the guide ring 21, ensuring accurate buffering action. The guide ring 21 is slidably connected to the outer wall of the guide post 22. The guide post 22 slides, compressing the spring 20 to buffer the swaying energy of the clamping upper seat 7. The outer wall of the guide ring 21 is fixedly connected to the spring 20, which absorbs and buffers the impact force transmitted by the guide ring 21, reducing the swaying of the clamping upper seat 7. The inner wall of the guide ring 21 is rotatably connected to the shaft 24, and the outer wall of the shaft 24 is fixedly connected to the connecting rod 25. The connecting rod 25 transmits the force transmitted by the connecting module 27 to the guide ring 21, acting as an intermediate bridge for force transmission in the buffer system. The inner wall of the connecting rod 25 is rotatably connected to the shaft 26, allowing the connecting module 27 and the connecting rod 25 to rotate relative to each other. The second shaft 26 is fixedly connected to the outer wall of the connecting module 27, which senses and transmits the swaying force of the clamping upper seat 7. It is the starting point for the power transmission of the buffer system. A steel rope 5 is fixedly connected to the upper seat 6 on the connecting steel plate. A rope winding device 3 is rotatably connected to the outer wall of the steel rope 5. A crane base 1 is fixedly connected to the lower surface of the rope winding device 3. A transport crane 2 is rotatably connected to the outer wall of the crane base 1. A movable boom 4 is set on the outer wall of the crane base 1. A spring 23 is set on the outer wall of the spring damper 19. The spring 23 further enhances the buffering effect based on the spring damper 19 and ensures the stability of the clamping mechanism. The other end of the spring 23 The upper seat 6 is fixedly connected to the inner wall of the connecting steel plate seat 6. The connecting steel plate seat 6 is connected to the clamping upper seat 7 through the spring damper 19 to help buffer the shaking of the clamping upper seat 7. The outer wall of the clamping upper seat 7 is fixedly connected to the outer wall of the connecting module 27. One side of the outer wall of the nut 18 is attached to the outer wall of the connecting steel plate seat 6. The upper surface of the connecting steel plate seat 6 is fixedly connected to the outer wall of the cylinder 8. The outer wall of the pushing roller 14 is provided with the connecting steel plate seat 6. The outer wall of the moving plate 16 is fixedly connected to the outer wall of the connecting module 15. The clamping arm 10 is set on the outer wall of the moving plate 16. The moving plate 16 is set above the clamping module 11 and below the cylinder 8.

[0029] Working principle: When using a steel structure transportation device for offshore wind turbine foundation construction for clamping, firstly, cylinder 8 is activated. Cylinder 8 outputs to push the push roller 14. The push roller 14 moves, pushing the moving plate 16 to move. The moving plate 16 moves, driving the connecting module 15 to move. The moving connecting module 15 moves, driving the rotating roller 17 to rotate. The connecting rod 13 moves through the rotating roller 17. The moving connecting rod 13 moves the rotating roller 12 to rotate. The moving rotating roller 12 moves, driving the clamping arm 10 to move. The moving clamping arm 10 moves, driving the clamping module 11 to clamp the object. The clamping arm 10 is guided to rotate through the rotating roller 9. The rotating roller 9 is fixed and rotated within the clamping upper seat 7.

[0030] Furthermore, when encountering strong winds or waves, the clamping upper seat 7 shakes, causing the connecting module 27 to move. The connecting module 27 is connected to the connecting rod 25 via the rotating shaft 26, and the connecting rod 25 is connected to the guide ring 21 via the rotating shaft 24. Thus, the shaking of the clamping upper seat 7 transmits force to the guide ring 21. The guide ring 21 then compresses the spring 20 by guiding and sliding through the guide post 22, thereby reducing the shaking. At the same time, the clamping upper seat 7 is connected to the connecting steel plate seat 6 via the spring damper 19. The spring damper 19 is equipped with a spring 23 on its outside to further reduce the shaking and achieve a buffering effect.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
