Description

Technical Field

[0001] This utility model relates to the field of marine transportation equipment technology, specifically a vessel transfer and lifting support device for offshore wind power monopile foundations. Background Technology

[0002] Offshore wind turbine monopile foundations are constructed from large-diameter steel pipes, with a weight ranging from 150 to 400 tons. They are suitable for offshore wind farm projects in shallow or medium-water areas with relatively good soil conditions. Monopile foundations have advantages such as simple installation and no need for seabed preparation, but they also have disadvantages such as difficulty in moving them and the need for specialized piling vessels for offshore operations.

[0003] Once the monopile is transported to the piling vessel by a crane, its large size and heavy weight make it difficult to move on the deck by manpower. Existing technology for moving monopiles by crane is not only inconvenient to operate, but also requires the crane to move back and forth, reducing transportation efficiency. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a vessel-sliding lifting support device for offshore wind power monopile foundations, which has the advantage of quickly moving and transporting monopiles on the piling vessel, and solves the problem of low placement efficiency and the need for cranes to move back and forth when using cranes to place monopiles in the existing technology.

[0005] (II) Technical Solution: To achieve the above-mentioned goal of placing each monopile stably and separately, ensuring that the monopiles do not collide with each other and cause damage, this utility model provides the following technical solution: A vessel-to-ship sliding and lifting support device for offshore wind power monopile foundations, used in conjunction with a crane, includes a mobile transport frame and a support frame. The upper end of the support frame is provided with a placement surface for placing monopiles. The support frame is located on the side of the mobile transport frame. The mobile transport frame includes a lifting frame and a mobile base. The lifting frame is located above the mobile base. Lifting mechanisms are provided on both sides of the lifting frame. Under the action of the lifting mechanisms, the lifting frame has a degree of freedom of movement in the vertical direction. A track is provided below the mobile base. A moving mechanism is provided on the lower surface of the mobile base. A slot is opened at the upper end of the mobile transport frame for placing monopiles. When the lifting mechanism is not activated, the vertical height of the slot is lower than the placement surface of the support frame.

[0006] Preferably, the moving mechanism includes pulleys and a rotary motor. The moving base is connected to the track via the pulleys. The rotary motor is installed inside the moving base, and the rotor of the rotary motor is connected to the pulleys. The number of pulleys is not less than two.

[0007] Preferably, the number of the mobile transport frames in the axial direction of a single pile is not less than two, that is, the mobile transport frames are provided at both ends of the single pile.

[0008] Preferably, the lifting mechanism includes a lifting motor, which is fixedly installed on both sides of the movable base. The lifting motor includes a push rod, the top end of which is connected to both sides of the lifting frame. The lifting frame moves vertically through the movement of the push rod.

[0009] Preferably, the slot is arc-shaped, and a support pad is arranged in an array along the circumference of the arc inside the slot. The upper surface of the support pad is provided with an anti-slip pad made of elastic material.

[0010] (III) Beneficial Effects: Compared with the prior art, this utility model provides a vessel-sliding and lifting support device for offshore wind power monopile foundations, which has the following beneficial effects:

[0011] 1. This offshore wind power monopile foundation vessel transfer and lifting support device uses a mobile transport frame to transfer and transport monopiles from fixed supports. When a crane lifts a monopile and places it on the nearest fixed support below, the mobile transport frame moves to the corresponding position on the fixed support via the cooperation of the lower rails, pulleys, and an internal rotary motor. It passes under the monopile, aligning the slot with the monopile. The lifting motor and push rod then raise the lifting frame, bringing the slot into contact with the monopile surface, continuing upwards until the monopile is lifted away from the fixed support. Maintaining this height, it transports the monopile towards the end of the rails. Once stopped, the lifting frame lowers and places the monopile on the selected fixed support surface, completing the transport. This invention significantly improves construction efficiency. Compared to currently widely used traditional technologies, this device significantly reduces reliance on manpower, lowers worker labor intensity, eliminates the need for crane reciprocation, and improves operational accuracy and safety.

[0012] 2. This type of offshore wind power monopile foundation vessel-mounted sliding and lifting support device, through the cooperation of a mobile transport frame and a support frame, transports monopiles one by one, fundamentally avoiding the collision risk that may occur between monopiles in traditional methods, and greatly reducing safety hazards during construction. Furthermore, an arc-shaped slot is provided at the upper end of the mobile transport frame, and an array of support pads are installed inside the slot. The upper surface of the support pads is equipped with an anti-slip pad. While maintaining the same weight of the monopile, the contact area is reduced, thereby increasing friction and effectively preventing the monopile from shaking and sliding during transportation. This avoids collisions between the monopile and the slot during transportation, protects the outer surface of the monopile, and improves stability during transportation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0018] Please see Figures 1-3 A vessel-mounted sliding and lifting support device for offshore wind turbine monopile foundations, used in conjunction with a crane, includes a mobile transport frame 1 and a support frame 2. The upper end of the support frame 2 is provided with a placement surface 21 for placing the monopile. In this embodiment, two support frames 2 are respectively provided at both ends of each monopile to separate and support the monopile, ensuring that they do not collide with each other and avoid damage. The number of mobile transport frames 1 in the axial direction of each monopile is not less than two, that is, mobile transport frames 1 are provided at both ends of the monopile to ensure the stability of the monopile during transportation. The support frame 2 is located on the side of the mobile transport frame 1 to ensure that the mobile transport frame 1 does not collide with the support frame 2 when moving. The mobile transport frame 1 includes a lifting frame 11 and a mobile base 12, with the lifting frame 11 mounted on the mobile base 1. Above the support frame 11, lifting mechanisms 3 are provided on both sides. Under the action of the lifting mechanisms 3, the lifting frame 11 has a degree of freedom of movement in the vertical direction and can lift the single pile above. A track 5 is provided below the movable base 12, and a moving mechanism 4 is provided on the lower surface of the movable base 12. A slot 13 is opened at the upper end of the movable transport frame 1. The slot 13 is used to place the single pile. The slot 13 is arc-shaped. A support pad 131 is arranged in an array along the circumference of the arc inside the slot 13. An anti-slip pad made of elastic material is provided on the upper surface of the support pad 131 to increase the friction between the support pad 131 and the single pile. When the lifting mechanism 3 is not activated, the height of the slot 13 in the vertical direction is lower than the placement surface 21 of the support frame 2, ensuring that the movable transport frame 1 can pass under the support frame 2.

[0019] In this embodiment, please refer to Figures 2-3 The moving mechanism 4 includes pulleys 41 and a rotary motor. The moving base 12 is connected to the track 5 through the pulleys 41. The rotating motor is installed inside the moving base 12. The rotor of the rotating motor is connected to the pulleys 41. There are no fewer than two pulleys 41. The operator can control the movement of the moving base 12 by controlling the rotation of the motor rotor, so that it can drive the single pile above to move along the track 5.

[0020] In this embodiment, please refer to Figures 2-3 The lifting mechanism 3 includes a lifting motor 31, which is fixedly installed on both sides of the movable base 12. The lifting motor 31 includes a push rod 32, the top of which is connected to both sides of the lifting frame 11. When the operator controls the lifting motor 31 to push the push rod 32, the lifting frame 11 moves vertically through the movement of the push rod 32.

[0021] Working principle: When the crane lifts a single pile and places it on the nearest fixed support below, the moving transport frame 1 moves to the corresponding position of the fixed support through the cooperation of the lower track 5, pulley 41 and internal rotary motor, and passes under the single pile, aligning the slot 13 with the single pile. Through the movement of the lifting motor 31 and push rod 32, the lifting frame 11 is lifted, so that the slot 13 contacts the surface of the single pile and continues to rise until the single pile is lifted away from the fixed support. Then, it is transported at this height towards the end of the track 5. After stopping, the lifting frame 11 lowers and places the single pile into the placement surface 21 of the selected fixed support, completing the transportation.

[0022] In summary, this offshore wind power monopile foundation vessel-mounted sliding lifting support device, through the cooperation of the mobile transport frame 1 and the support frame 2, transports monopiles one by one, fundamentally avoiding the collision risk that may occur between monopiles in traditional methods, and greatly reducing safety hazards during construction. Furthermore, an arc-shaped slot 13 is provided at the upper end of the mobile transport frame 1, and an array of support pads 131 are installed inside the slot 13. The upper surface of the support pads 131 is provided with an anti-slip pad, which reduces the contact area while keeping the weight of the monopile constant, thereby increasing friction and effectively preventing the monopile from shaking and sliding during transportation, avoiding collisions between the monopile and the slot 13 during transportation, protecting the outer surface of the monopile, and improving stability during transportation. This utility model not only significantly improves construction efficiency, but also significantly reduces reliance on manpower compared to currently widely used traditional technologies, lowers the labor intensity of workers, eliminates the need for cranes to move back and forth, and improves operational accuracy and safety.
