Description

Technical Field

[0001] This application belongs to the technical field of grouting operation equipment, and particularly relates to a material loading structure for offshore wind power jacket and a grouting operation device. Background Technology

[0002] Offshore wind turbine jacket foundation grouting equipment is a specialized device used during the installation of offshore wind turbine jacket foundations to inject grout into the gap between the jacket foundation and the pile foundation. Its core function is to inject grouting material into the gap through pumping or other methods, forming a strong connection and ensuring the overall stability of the jacket foundation. This equipment typically includes a grouting pump, a mixing system, delivery pipelines, and a control system. Due to the need to adapt to the complex offshore operating environment, such equipment often features high automation and strong corrosion resistance to ensure the accuracy and reliability of the grouting operation.

[0003] Existing grouting equipment typically includes a support platform, and a mixing system, a water supply system, a control system, and a grouting system installed on the platform. During operation, crawler cranes or cranes are usually used to lift ton bags of grouting material to the top of the dustproof cylinder of the mixer. The bags are then opened using a bag breaker inside the dustproof cylinder, allowing the material to fall into the mixer. The discarded bags are then removed manually, and the water supply, mixing, and unloading operations are completed through the control system.

[0004] The technology involved in this application is applied to the offshore operating environment. The offshore construction window is subject to considerable uncertainty, and the increasingly stringent safety management of offshore construction imposes stricter restrictions on lifting operations, further hindering the progress of offshore grouting operations.

[0005] Specifically, the construction vessel is prone to swaying due to water currents and sea breezes, especially during the rupture of ton bags, where the crane's swaying is more pronounced, increasing the safety risks for workers. Current rupture methods rely on the bag falling under its own weight to a rupture device at a designated location, which then punctures the bag and releases the material. In practice, some bags experience poor rupture results due to misalignment during descent, resulting in small openings and slow material discharge. Even after normal rupture, the initial tear is difficult to expand further, limiting the material discharge speed. Manual assistance from workers is often required to shake or adjust the bag to improve efficiency, making the entire grouting operation inconvenient.

[0006] Therefore, there is an urgent need to develop a material loading structure with low lifting requirements to overcome the safety issues caused by current crane loading, improve the packing structure, and achieve a continuous and stable supply of materials, thereby reducing the adverse effects of complex offshore working conditions on construction. Summary of the Invention

[0007] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this application is to provide a bulging structure for offshore wind power jackets and a grouting operation device.

[0008] To solve the above-mentioned technical problems, this application provides the following technical solution: This application proposes a material loading structure for offshore wind turbine jackets, comprising: a loading bin with multiple limiting plates, a first lifting assembly, and at least two slide rails with deburring blades. The limiting plates are rotatably connected to the loading bin, and the ends of the two slide rails are disposed opposite each other within the loading bin. The first lifting assembly is connected to the slide rails. When the limiting plates are in the initial position, the multiple limiting plates form a material guide opening, and the deburring blades are located at adjacent ends of the two slide rails.

[0009] Optionally, in the above-mentioned offshore wind turbine jacket loading structure, when the limiting plate rotates relative to the inner wall of the loading bin from its initial position, the packing cutter slides relative to the slide rail, and the first lifting assembly moves downward relative to the loading bin.

[0010] Optionally, in the above-mentioned offshore wind turbine jacket loading structure, the packing cutter is a right-angled triangle, with one right-angled side of the two packing cutters facing away from each other, and the other right-angled side connected to the slide rail, and the hypotenuse has a cutting edge.

[0011] Optionally, in the above-mentioned offshore wind turbine jacket loading structure, the limiting plate and the loading bin are fixed in relative positions by rods, and the inner wall of the loading bin is provided with a sliding groove that cooperates with the movement of the rods.

[0012] Optionally, the above-mentioned offshore wind turbine jacket loading structure further includes a vibrator, which is installed on the loading hopper.

[0013] Optionally, the above-mentioned offshore wind turbine jacket loading structure further includes: a grid plate and a second lifting assembly, the second lifting assembly being connected to the grid plate, the grid plate being disposed above the slide rail, and the grid plate having a clearance portion for avoiding the packing knife.

[0014] Optionally, the above-mentioned offshore wind turbine jacket loading structure further includes: a baffle plate, which is disposed below the slide rail and is inclinedly disposed in the loading bin, with the lower end of the baffle plate connected to the discharge port of the loading bin.

[0015] This application also proposes a grouting operation device, including the aforementioned offshore wind turbine jacket loading structure.

[0016] Optionally, the above-mentioned grouting device further includes a forklift that transports ton bags to the top of the loading structure.

[0017] Optionally, the above-mentioned grouting operation device further includes: a conveyor frame and a mixing chamber, wherein the feeding structure is connected to the mixing chamber via the conveyor frame.

[0018] Compared with the prior art, this application has the following technical effects: In the initial position, i.e. before the bag breaks, the feeding structure of this application forms a guiding channel through the guide opening, and uses the weight of the ton bag to achieve automatic centering, effectively overcoming the problem of landing point deviation caused by swaying during offshore operations, ensuring accurate bag breakage position, and significantly suppressing ton bag swaying, thus improving operational safety. The feeding structure of this application uses a rotating limit plate, a sliding bag-breaking knife, a first lifting component and a vibrator to work together to make the material in the ton bag fall efficiently and improve the operation efficiency. This application adopts a low lifting height loading structure design, which effectively reduces the overall height of the lifting operation, reduces the positioning difficulties and safety risks caused by the height and sway of traditional crawler cranes / cranes, reduces the stringent requirements on sea conditions, and thus extends the effective working time window.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 4 As shown, one embodiment of this application proposes a material loading structure for offshore wind turbine jackets, comprising: a loading bin 9 with multiple limiting plates 953, a first lifting assembly 91, and at least two slide rails 933 with deburring blades 932. The limiting plates 953 are rotatably connected to the loading bin 9, and the ends of the two slide rails 933 are disposed opposite each other within the loading bin 9. The first lifting assembly 91 is connected to the slide rails 933. When the limiting plates 953 are in the initial position, the multiple limiting plates 953 form a material guide opening, and the deburring blades 932 are located at adjacent ends of the two slide rails 933.

[0022] In this embodiment, the number of limiting plates 953, slide rails 933, and bag-breaking knives 932 are all set to four. Those skilled in the art will have the motivation to adapt the quantities of the above structures. The limiting plates 953 are trapezoidal in shape, with their bottom edges hinged to the edge of the feeding hopper 9. The top edges of the four limiting plates 953 form a rectangular guide opening to guide the ton bag into the feeding hopper 9. Those skilled in the art will have the motivation to change the shape of the guide opening, such as adjusting it to a circle. In the initial position, the limiting plates 953 are distributed at approximately a 90° angle to the wall of the feeding hopper 9. The slide rails 933 and the number of bag-breaking knives 932 are correspondingly arranged, with the bag-breaking knives 932 mounted on the slide rails 933. The four slide rails 933 are arranged in a cross shape. In the initial position, the bag-breaking knives 932 are concentrated at the ends of the slide rails 933, i.e., in the middle of the cross-shaped structure, below the guide opening. With the above settings, in the initial position, i.e. the unbroken stage, the guide port forms a guiding channel, and the weight of the ton bag is used to achieve automatic centering, which effectively overcomes the problem of landing point deviation caused by swaying during offshore operations, ensures accurate bag breaking position, and significantly suppresses ton bag swing, thereby improving operational safety.

[0023] Specifically, the limiting plate 953 and the feeding bin 9 are hinged together by a hinge 954; the packing cutter 932 moves on the slide rail 933 via a push-pull rod 934. Optionally, the push-pull rod 934 is a hydraulic push-pull rod 934.

[0024] Furthermore, when the limiting plate 953 rotates relative to the inner wall of the feeding bin 9 from its initial position, the packing knife 932 slides relative to the slide rail 933, and the first lifting assembly 91 moves downward relative to the feeding bin 9.

[0025] In this embodiment, the ton bag is positioned on the limiting plate 953, and the ton bag is punctured by the bag-breaking knife 932, avoiding the inaccurate positioning caused by relying on hanging and impact to puncture the bag in the prior art. After the initial puncture, the limiting plate 953 continues to rotate upward to the inner wall of the hopper 9, while the four bag-breaking knives 932 move from one end of the slide rail 933 to the other end, making the puncture area of ​​the ton bag larger. At the same time, the first lifting component 91 drives the slide rail 933 to move slowly downward to facilitate the material in the ton bag to scatter.

[0026] Optionally, the limiting plate 953 and the feeding bin 9 are fixed in relative position by a rod 952, and the inner wall of the feeding bin 9 is provided with a sliding groove 951 that moves in coordination with the rod 952.

[0027] In this embodiment, each limiting plate 953 is connected to the feeding bin 9 by a hydraulic rod. The inner wall of the feeding bin 9 is also provided with a sliding groove 951 that cooperates with the hydraulic rod, so that the hydraulic rod can provide strong support in real time as the limiting plate 953 rotates.

[0028] Specifically, the package-breaking knife 932 is a right-angled triangle with two right-angled sides facing away from each other, and the other right-angled side is connected to the slide rail 933. The hypotenuse has a blade to facilitate the movement of the package-breaking knife 932 on the slide rail 933 and to expand the breaking area.

[0029] Optionally, the feeding structure further includes a vibrator, which is disposed on the feeding hopper 9.

[0030] In this embodiment, a vibrator is provided on the outer wall of the feeding hopper 9, so that the limiting plate 953 has a patting function during rotation, which can help shake off the material in the ton bag and avoid obstruction when the material falls.

[0031] Optionally, the feeding structure further includes: a grid plate 94 and a second lifting component 92, the second lifting component 92 being connected to the grid plate 94, the grid plate 94 being disposed above the slide rail 933, and the grid plate 94 being provided with a clearance portion for avoiding the pack breaking knife 932.

[0032] In this embodiment, the grid plate 94 is disposed above the slide rail 933 to prevent clumped material from falling. After all the material in the ton bag has fallen, the grid plate 94 rises under the drive of the second lifting component 92, pushing the empty ton bag and clumped material to the top of the feeding hopper 9 for easy picking up by the staff.

[0033] Optionally, the first lifting assembly 91 includes: a first power element 911, a first hydraulic base 912, a first hydraulic cylinder 913 and a first hydraulic rod 914 connected in sequence, wherein the first hydraulic rod 914 is connected to the bottom of the slide rail 933 through a connecting plate 931.

[0034] Optionally, the second lifting assembly 92 includes: a second power element 922, a second hydraulic base 921, a second hydraulic cylinder 923, and a second hydraulic rod 924 connected in sequence. Optionally, the feeding structure further includes a baffle plate 8, which is disposed below the slide rail 933 and is inclinedly disposed inside the feeding bin 9. The lower end of the baffle plate 8 is connected to the discharge port of the feeding bin 9.

[0035] In this embodiment, the baffle plate 8 is located below the slide rail 933 and has a clearance portion for the first lifting component 91 and the second lifting component 92, so that the material falling through the grid plate 94 is difficult to clean and hinders the normal operation of the feeding hopper 9. The baffle plate 8 is inclinedly set inside the feeding hopper 9, and its lower end is connected to the discharge port of the feeding hopper 9 to facilitate the discharge of residual material.

[0036] Another embodiment of this application also proposes a grouting operation device, including the aforementioned offshore wind turbine jacket material loading structure.

[0037] In this embodiment, the grouting device utilizes the aforementioned loading structure, avoiding the use of cranes to suspend and drop ton bags as in existing technologies. This reduces the impact of sea winds during offshore operations, lowers the probability of safety accidents, and aligns with the industry trend of avoiding crawler cranes on operating vessels. In existing technologies, the boom height of a crawler crane is approximately 3 meters when horizontal, and the operating height is 8-10 meters, with a maximum operating height exceeding 20 meters, making it prone to tipping and displacement. While crawler cranes are safer than crawler cranes because their base can be fixed to the ship's side, their lifting height is still relatively high, making them a type of equipment to be avoided in grouting devices. In this embodiment, a forklift is used to transport the ton bags to the loading structure. The forklift's operating height is 2-4 meters, a trend that aligns with the new requirements of offshore operations.

[0038] In this embodiment, the grouting device further includes a conveyor frame 7 and a mixing chamber 42, wherein the feeding structure is connected to the mixing chamber 42 via the conveyor frame 7.

[0039] In this embodiment, the material in the feeding structure is transferred to the mixing chamber 42 via the conveyor frame 7. The bottom of the mixing chamber 42 is equipped with a water storage tank 52 for storing fresh water required for grouting operations. A water storage tank 51 is connected to the water storage tank 52, and the water storage tank 51 is equipped with a weighing unit for weighing the water volume.

[0040] Specifically, the mixing chamber 42 is equipped with a mixing motor 44 for mixing materials, and the mixing chamber 42 is also equipped with a discharge motor 41 to control the opening and closing of the discharge gate 43 of the mixing chamber 42 to control the discharge.

[0041] Furthermore, the grouting operation device also includes a control component 6, which is electrically connected to the water storage tank 51, the mixing chamber 42, and the feeding structure, and is used to control the water supply, mixing, and unloading operations, thereby completing the electrical and hydraulic execution of the grouting operation device.

[0042] like Figure 5 As shown, in this embodiment, the number of grouting devices is set to two sets, and they are arranged symmetrically to improve work efficiency. The grouting device is set inside the support frame 1, and is equipped with a ladder 3 for workers to work on, and a guardrail 2 for the safety of workers.

[0043] The grouting device proposed in this embodiment significantly improves the efficiency and safety of grouting operations and extends the offshore operation window through its low lifting height design and automated process.

[0044] The working process for this application is as follows: 1. Preparation and Positioning: The ton bag is lifted by a forklift to the top of the loading structure. At this time, the control lever 952 extends, causing the four limiting plates 953 to be in a closed state, forming a guide channel that gradually narrows from top to bottom. Under the action of gravity, the ton bag slides down along this channel and is automatically guided to the center position of the loading bin 9, effectively overcoming the positioning deviation caused by the hull swaying.

[0045] 2. Active Bag Breaking: The initial position of the limiting plate 953 is at an angle of approximately 90° with the wall of the feeding hopper 9. After the ton bag is stably centered, the limiting plate 953 is controlled to rotate. When the limiting plate 953 rotates to an angle of 45° with the inner wall of the feeding hopper 9, the first lifting component 91 is activated. The first hydraulic rod 914 pushes the bag-breaking knife 932 upward from bottom to top, and the bag-breaking knife 932 pierces into the ton bag, completing the initial piercing. When the limiting plate 953 continues to rotate to an angle of 30°, the push-pull rod 934 is controlled to push outward along the slide rail 933, causing the four bag-breaking knife 932-shaped structures to expand radially. At the same time, the first lifting component 91 descends in coordination, thereby tearing and expanding the rupture, accelerating the falling of the powder. In addition, the limiting plate 953 vibrates with the vibration motor 96, and the limiting plate 953 acts as a patting action on the ton bag, further accelerating the falling of the powder.

[0046] 3. Waste handling and cleaning: After all the powder has fallen into the feeding hopper 9, empty waste bags or any clumps will remain on the grid plate 94. At this time, the second lifting component 92 is activated, and the second hydraulic rod 924 lifts the grid plate 94 and the waste on it to the top of the material cylinder, making it convenient for operators to collect and clean up, thus maintaining the cleanliness of the work area.

[0047] 4. Powder conveying: The powder is stored in the feeding hopper 9. The feeding hopper 9 is controlled by the control component 6 to move upward along the conveyor frame 7. After reaching the predetermined position, the powder enters the mixing chamber 42 from the discharge gate 43.

[0048] 5. Mixing and grouting: The powder and water precisely injected from the water storage tank 51 are mixed into a uniform slurry by the mixing motor 44 in the mixing chamber 42, and finally pumped to the guide frame for grouting operation through the discharge gate 43 controlled by the discharge motor 41.
