Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to a lifting mechanism for an adjustable monopile transport support. Background Technology

[0002] In large-scale engineering projects such as offshore wind power, bridge engineering, and port infrastructure, monopiles are core load-bearing components. When monopiles are transported from the production site to the construction site, they need to be stably fixed by special transport supports to ensure that the pile body does not deform or get damaged during transportation.

[0003] For example, patent number CN219822371U discloses a single-pile transport support, which includes a support base and a lifting mechanism disposed inside the support base. The lifting mechanism includes a sliding component, a lifting component, and a limiting component.

[0004] While the aforementioned devices have solved the fixing problem, the clamping structures are mostly designed with fixed dimensions, which can only be adapted to single piles of a single diameter. When faced with the transportation needs of single piles of different diameters, it is necessary to customize brackets of corresponding sizes, which not only increases the investment cost of engineering equipment, but also prolongs the construction preparation cycle, making it difficult to meet the needs of large-scale transportation operations of single piles of multiple specifications.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A lifting mechanism for an adjustable monopile transport support includes: a lifting structure, wherein a placement structure is slidably connected to the inner wall of the lifting structure; the placement structure includes a lifting plate, a support plate is fixedly connected to the outer wall of the lifting plate, diagonal bracing plates are symmetrically fixedly connected to the outer wall of the bottom of the support plate, a slider is fixedly connected to the outer wall of the diagonal bracing plates, a ball bearing is rotatably connected to the inner wall of the slider, and adjustment grooves are symmetrically formed on the outer wall of the top of the support plate.

[0007] Preferably, the balls are arranged vertically along the inner wall of the slider, the support plate is L-shaped, the horizontal section of the L-shaped support plate provides bottom support for the single pile, and the inclined brace plate enhances the support rigidity and avoids deformation under stress.

[0008] Preferably, the inner wall of the adjusting groove is rotatably connected to a bidirectional threaded rod, the outer wall of the bidirectional threaded rod is symmetrically threaded to an adjusting block, the outer wall of the top of the adjusting block is fixedly connected to an arc-shaped support block, and the outer wall of the arc-shaped support block is fixedly connected to an anti-slip pad.

[0009] Preferably, the outer wall of the adjusting block is slidably connected to the inner wall of the adjusting groove, and the outer wall of the bottom of the arc-shaped support block is slidably connected to the outer wall of the top of the support plate. When the bidirectional threaded rod is rotated, since the adjusting block and the bidirectional threaded rod are symmetrically threaded and the outer wall of the adjusting block is slidably engaged with the inner wall of the adjusting groove, the bidirectional threaded rod rotates and drives the two adjusting blocks on both sides to move synchronously towards the center along the adjusting groove.

[0010] Preferably, the lifting structure includes a lifting frame, a lifting screw is rotatably connected to the inner wall of the lifting frame, a guide rod is fixedly connected to the inner wall of the lifting frame, and sliding grooves are symmetrically formed on the outer wall of the lifting frame.

The inner wall of the lifting plate is threadedly connected to the lifting screw, and the inner wall of the lifting plate is slidably engaged with the guide rod fixed to the lifting frame. Therefore, when the lifting screw rotates, the lifting plate rises vertically along the direction of the guide rod.

[0012] (III) Beneficial Effects This utility model provides a lifting mechanism for an adjustable monopile transport support. It has the following advantages: (i) The placement structure drives the arc-shaped support blocks on both sides to move synchronously in opposite directions through a bidirectional threaded rod.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-6 This utility model provides a technical solution: an adjustable single-pile transport support lifting mechanism, comprising: a lifting structure 1, with a placement structure 2 slidably connected to the inner wall of the lifting structure 1; the placement structure 2 includes a lifting plate 21, a support plate 22 fixedly connected to the outer wall of the lifting plate 21, a diagonal brace 23 symmetrically fixedly connected to the outer wall of the bottom of the support plate 22, a slider 24 fixedly connected to the outer wall of the diagonal brace 23, a ball bearing 25 rotatably connected to the inner wall of the slider 24, and symmetrical adjustment grooves 26 opened on the outer wall of the top of the support plate 22.

[0017] Preferably, the balls 25 are arranged vertically along the inner wall of the slider 24, the support plate 22 is L-shaped, the horizontal section of the L-shaped support plate 22 provides bottom support for the single pile, and the inclined brace 23 enhances the support rigidity and avoids deformation under stress.

[0018] Preferably, the inner wall of the adjusting groove 26 is rotatably connected to a bidirectional threaded rod 27, the outer wall of the bidirectional threaded rod 27 is symmetrically threaded to an adjusting block 28, the outer wall of the top of the adjusting block 28 is fixedly connected to an arc-shaped support block 29, and the outer wall of the arc-shaped support block 29 is fixedly connected to an anti-slip pad 291.

[0019] The outer wall of the adjusting block 28 is slidably connected to the inner wall of the adjusting groove 26, and the outer wall of the bottom of the arc-shaped support block 29 is slidably connected to the outer wall of the top of the support plate 22. When the bidirectional threaded rod 27 is rotated, since the adjusting block 28 and the bidirectional threaded rod 27 are symmetrically threaded, and the outer wall of the adjusting block 28 is slidably engaged with the inner wall of the adjusting groove 26, the bidirectional threaded rod 27 rotates and drives the two adjusting blocks 28 on both sides to move synchronously towards the center along the adjusting groove 26.

[0020] The lifting structure 1 includes a lifting frame 11, a lifting screw 12 is rotatably connected to the inner wall of the lifting frame 11, a guide rod 13 is fixedly connected to the inner wall of the lifting frame 11, and sliding grooves 14 are symmetrically opened on the outer wall of the lifting frame 11.

[0021] The outer wall of the lifting screw 12 is threadedly connected to the inner wall of the lifting plate 21, the outer wall of the guide rod 13 is slidably connected to the inner wall of the lifting plate 21, and the inner wall of the slide groove 14 is slidably connected to the outer surfaces of the slider 24 and the ball 25. The drive assembly of the lifting structure 1 is activated, driving the lifting screw 12 to rotate on the inner wall of the lifting frame 11. The inner wall of the lifting plate 21 is threadedly connected to the lifting screw 12, and the inner wall of the lifting plate 21 is slidably engaged with the guide rod 13 fixed to the lifting frame 11. Therefore, when the lifting screw 12 rotates, the lifting plate 21 rises vertically along the direction of the guide rod 13.

[0022] In use, the single pile is placed on the placement structure 2, and the placement structure 2 is lifted by the servo motor of the lifting structure 1. When the mechanism is not in operation, the lifting plate 21 is at the lowest position of the lifting frame 11, and the two arc-shaped support blocks 29 are at the outermost side of the adjustment groove 26. The arc-shaped support blocks 29 form the maximum clamping distance, which is convenient for the single pile hoisting and placement. The slider 24 is embedded in the slide groove 14 of the lifting frame 11, and the ball bearing 25 is in contact with the inner wall of the slide groove 14, providing a guiding foundation for subsequent lifting and lowering movements. The anti-slip pad 291 remains in a natural state, waiting to contact the outer wall of the single pile. The monopile to be transported is hoisted onto the support plate 22 using a lifting device and slowly placed between the two arc-shaped support blocks 29. The bottom of the monopile initially contacts the top outer wall of the support plate 22. The horizontal section of the L-shaped support plate 22 provides bottom support for the monopile, and the inclined support plate 23 enhances the support rigidity and prevents deformation under stress. The bidirectional threaded rod 27 is rotated. Since the adjusting block 28 is symmetrically threaded to the bidirectional threaded rod 27, and the outer wall of the adjusting block 28 slides with the inner wall of the adjusting groove 26, the rotation of the bidirectional threaded rod 27 drives the two adjusting blocks 28 to move synchronously towards the center along the adjusting groove 26. The adjusting blocks 28 drive the top arc-shaped support blocks 29 to move closer synchronously until the anti-slip pad 291 on the outer wall of the arc-shaped support block 29 is tightly attached to the outer wall of the monopile. The elasticity and friction of the anti-slip pad 291 limit the lateral displacement of the monopile. When the clamping force reaches the preset requirement, the rotation of the bidirectional threaded rod 27 is stopped, completing the lateral fixation of the monopile and adapting to the clamping requirements of monopile of different diameters. The drive assembly of the lifting structure 1 is activated, driving the lifting screw 12 to rotate on the inner wall of the lifting frame 11. The inner wall of the lifting plate 21 is threadedly connected to the lifting screw 12, and the inner wall of the lifting plate 21 is slidably engaged with the guide rod 13 fixed to the lifting frame 11. Therefore, when the lifting screw 12 rotates, the lifting plate 21 rises vertically along the direction of the guide rod 13. During the rise of the lifting plate 21, the support plate 22 fixed on its outer wall synchronously drives the single pile to move upward. At the same time, the inclined support plate 23 at the bottom of the support plate 22 drives the slider 24 to slide along the slide groove 14 of the lifting frame 11. The ball bearings 25 on the inner wall of the slider 24 roll and contact the inner wall of the slide groove 14, converting sliding friction into rolling friction, reducing lifting resistance and improving smoothness of movement. When a single pile is raised to the target height, the lifting screw 12 is stopped. The lifting structure 1 maintains the lifting height through the self-locking characteristic of the thread, thus avoiding unexpected descent.
