Description

Technical Field

[0001] This utility model relates to the field of single pile tooling technology, and in particular to a wedge block structure for a large-diameter rolling tooling for single piles. Background Technology

[0002] In recent years, with the development of the offshore wind power industry, wind turbine locations have gradually shifted from shallow sea areas to deep sea areas. The diameter and length of the monopile structure of the foundation of offshore wind turbines are getting larger and larger, and the weight of the entire monopile is also getting heavier. Due to the excessive length and weight of the monopile, moving the entire monopile is very difficult, time-consuming and labor-intensive, requiring the use of roll-on / roll-off equipment to fix it in place for overall transportation.

[0003] Currently, Chinese Patent Publication No. CN214566015U discloses a gantry frame for rolling-on / roll-off loading of wind turbine pipe piles onto ships, comprising support legs, crossbeams, and retaining frames. A crossbeam is detachably connected to the upper ends of two support legs, and retaining frames are symmetrically and detachably connected to the upper ends of the crossbeams. Two crossbeam support legs are symmetrically fixed at the left and right ends of the lower end face of the crossbeams, and support legs are detachably connected to the lower ends of the crossbeam support legs. Support leg elbow plates are provided on the outer sides of the support legs. This utility model has a simple structure, is practical and convenient for lifting, and allows adjustment of the distance between the two retaining frames according to the diameter of the pipe pile to accommodate pipe piles of different sizes. It avoids the problem of the support legs colliding with the dock, strengthens the overall strength of the frame, and ensures stability during use.

[0004] This utility model uses two symmetrical wedge structures at the top to support the surface of a single pile. However, since the diameters of single piles of different sizes are different, the curvature of the surface is also different. Therefore, in order to ensure that the wedge structure fits the surface of the single pile, it is necessary to replace the wedge structure with one of different curvature, which is time-consuming and labor-intensive. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a wedge block structure for a large-diameter roll-on tooling for single piles, which solves the problem of time-consuming and labor-intensive work in the prior art that requires changing the wedge block structure with different degrees of surface curvature according to the different sizes of single piles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single-pile large-diameter roll-on tooling wedge structure includes a base, on which a first support rod and a plurality of second support rods are sequentially arranged.

[0008] The first support rod includes a first crossbar and two first legs fixedly disposed at both ends of the bottom of the first crossbar, with the lower ends of the first legs fixedly connected to the base.

[0009] The second support rod includes a second crossbar and two second legs fixedly disposed at both ends of the bottom of the second crossbar. The base is provided with a plurality of movable slots corresponding to the second legs. The top of the movable slot is provided with a through hole communicating with the outside. The lower end of the second leg passes through the through hole and is movably disposed in the movable slot. The bottom of the second leg is fixedly connected to a limit block, which is slidably disposed in the movable slot. The lower end of the limit block is fixedly connected to a spring, and the lower end of the spring is fixedly connected to the bottom of the movable slot.

[0010] Furthermore, a third support rod is provided at the end of the base away from the first support rod. The third support rod includes a third crossbar and two hydraulic telescopic rods fixedly disposed at both ends of the bottom of the third crossbar. The lower end of the hydraulic telescopic rods is fixedly connected to the base.

[0011] Furthermore, rubber pads are fitted on the outer walls of the first, second, and third crossbars.

[0012] Furthermore, the diameter of the limiting block is larger than the diameter of the through hole.

[0013] Furthermore, the number of the second support rods is 3-7.

[0014] Furthermore, the top surface of the base has a concave arc-shaped structure.

[0015] Furthermore, the second leg is perpendicular to the cross-section where the second leg intersects with the base.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] This utility model has a simple structure and strong practicality. The first support rod positions the monopile, ensuring that large-diameter monopiles are stably supported on top of the wedge structure. The second support rod, when placed on the wedge structure, exerts pressure on the second support rod due to its gravity, causing the second leg to compress the spring inwards into the movable groove. This brings the surface of the second crossbar into contact with the surface of the monopile. Simultaneously, the spring's restoring force acts on the second support rod, generating an upward supporting force on the monopile surface, thus supporting it. The multiple second support rods effectively disperse the pressure generated by the monopile, providing stable support. Furthermore, due to the spring's extensibility, the length of the second leg above the base can be adjusted within a certain range, accommodating monopiles of different sizes, thus improving versatility and work efficiency. The third support rod, after the monopile is stabilized, allows the hydraulic telescopic rod to abut against the monopile, limiting its movement and preventing swaying, thereby improving the stability of the monopile support.

Detailed Implementation

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] refer to Figures 1 to 5 This embodiment provides a single-pile large-diameter roll-on tooling 5 wedge block structure, including a base 1, on which a first support rod 2 and a plurality of second support rods 3 are sequentially arranged, with the first support rod 2 located at the lower end of the base 1.

[0026] The first support rod 2 includes a first crossbar 21 and two first legs 22 fixedly disposed at both ends of the bottom of the first crossbar 21. The lower ends of the first legs 22 are fixedly connected to the base 1. The first support rod 2 serves to position the monopile, ensuring that the monopile can be stably supported on the top of the wedge structure.

[0027] The second support rod 3 includes a second crossbar 31 and two second legs 32 fixedly disposed at both ends of the bottom of the second crossbar 31. The base 1 has multiple movable slots 11 corresponding to the second legs 32. The top of each movable slot 11 has a through hole 12 communicating with the outside. The lower end of each second leg 32 passes through the through hole 12 and is movably disposed within the movable slot 11. A limiting block 33 is fixedly connected to the bottom of each second leg 32 and is slidably disposed within the movable slot 11. A spring 34 is fixedly connected to the lower end of the limiting block 33, and the lower end of the spring 34 is fixedly connected to the bottom of the movable slot 11. When a monopile is placed on the wedge structure, the monopile exerts pressure on the second support rod 3 due to gravity, causing the second legs 32 to press against the spring 34 inwards towards the movable slot 11. This causes the surface of the second crossbar 31 to adhere to the surface of the monopile. Simultaneously, the rebound force of the spring 34 acts back onto the monopile through the second support rod 3, providing support to the surface of the monopile.

[0028] In this specific embodiment, a third support rod 4 is also provided at the end of the base 1 away from the first support rod 2. The third support rod 4 includes a third crossbar 41 and two hydraulic telescopic rods 42 fixedly disposed at both ends of the bottom of the third crossbar 41. The lower ends of the hydraulic telescopic rods 42 are fixedly connected to the base 1. After the monopile is placed stably, the extension and retraction of the hydraulic telescopic rods 42 are adjusted to make the third crossbar 41 contact the surface of the monopile, thereby fixing the monopile and preventing it from shaking, thus improving the placement stability of the monopile.

[0029] In this specific embodiment, rubber pads (not shown in the figure) are fitted on the outer walls of the first crossbar 21, the second crossbar 31, and the third crossbar 41. The rubber pads protect the surface of the single pile.

[0030] In this specific embodiment, the diameter of the limiting block 33 is larger than the diameter of the through hole 12. This ensures that the limiting block 33 is engaged within the movable groove 11, preventing the lower end of the second leg 32 from slipping out of the movable groove 11.

[0031] In this specific embodiment, the number of second support rods 3 is 3-7. Limiting the number of second support rods 3 is to ensure the supporting effect on the single pile. By distributing the stress points on the single pile through the supporting action of multiple second support rods 3, the stability of the single pile is improved.

[0032] In this specific embodiment, the top surface of the base 1 has a concave arc-shaped structure, which is adapted to the surface of the single pile.

[0033] In this specific embodiment, the second leg 32 is perpendicular to the tangential surface at the intersection of the second leg 32 and the base 1, which facilitates the smooth movement of the leg after being subjected to the force of a single pile.

[0034] The working principle of this utility model is as follows:

[0035] This utility model is used for placing large-diameter monopile 6. In use, the wedge structure is symmetrically installed on the large-diameter rolling fixture 5 of the monopile, and then the large-diameter monopile 6 is installed on the wedge structure. The first support rod 2 on the two wedge structures plays a positioning role for the monopile, ensuring that the large-diameter monopile 6 can be stably supported on the top of the wedge structure. At the same time, the monopile will exert pressure on the second support rod 3 due to gravity, causing the second leg 32 to squeeze the spring 34 inward into the movable groove 11, so that the surface of the second crossbar 31 is in contact with the surface of the monopile. At the same time, the rebound force of the spring 34 will act back to the monopile through the second support rod 3, which plays a supporting role for the surface of the monopile. After the monopile is placed stably, the hydraulic telescopic rod 42 is adjusted to make the third crossbar 41 abut against the monopile, which can limit the monopile and prevent the monopile from shaking, thereby improving the support stability of the monopile.

[0036] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
