Description

Technical Field

[0001] The utility model relates to the technical field of single pile cages, in particular to an overall assembly tooling for offshore wind power single pile cages. Background Art

[0002] There are many types of offshore wind turbine foundations. The single pile foundation has the advantages of simple structure, clear force, simple construction and construction process, short construction period, and good economy. It is currently the most widely used wind turbine foundation type in offshore wind farms. The single pile foundation usually needs to be used together with the cage auxiliary components to meet the needs of construction and subsequent maintenance. The cage auxiliary components are mainly composed of outer platform, inner platform, mooring components, cable pipes and sacrificial anode components. They have complete functions and are easy to construct and install on site. After being assembled on land, they can be directly transported to the pile foundation for hoisting and installation.

[0003] The traditional 8-point support tooling is used, in which the bottom ring beam is placed on 8 supporting points, two adjacent supporting points are connected in pairs, and diagonal braces are added on the outside to ensure that the ring beam is evenly stressed. However, this tooling occupies a large area of ​​the site and consumes a lot of materials. In order to ensure the stability of the tooling, diagonal braces are added on the outside to reinforce it, which expands the area occupied by the tooling and occupies a large area of ​​the site. The tooling is arranged on 8 supporting points, the tooling structure is heavy and has not formed a whole, and it is not convenient to use.

[0004] Therefore, we proposed an offshore wind power single pile cage assembly tooling to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. A ring-shaped assembly tool is used for the cage assembly. This tool structure effectively ensures the balanced force of the bottom ring beam and effectively avoids the installation position of the cable pipe bell mouth.

[0013] 2. The bottom plate is connected to the original ground through embedded steel bars, and the tooling is connected to the bottom ring beam through high-strength bolts.

[0015] 4. By setting a hook to connect with external lifting equipment, it is convenient to lift the entire device, and by setting a torsion spring, the hook can be stored in the inner cavity of the storage slot, which can avoid the hook being dragged outside when not in use, affecting the normal use of the subsequent device.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-5 The offshore wind power single pile cage assembly tooling includes a supporting top plate 1, and a plurality of H-shaped steels 2 are provided at the bottom of the supporting top plate 1. The bottom of the H-shaped steel 2 is provided with a T-shaped plate 6, and the T-shaped plate 6 and the H-shaped steel 2 are connected by bolts. The bottom of the T-shaped plate 6 is jointly fixed with a ring beam 5, and the bottom of the H-shaped steel 2 is fixed with a support leg 3, and the bottom of the support leg 3 is fixed with a bottom plate 4. The bottom plate 4 is connected to the original ground through embedded steel bars, and the tooling is connected to the bottom ring beam 5 through high-strength bolts. The entire cage and the original ground are almost integrated, which effectively enhances the wind and impact resistance of the structure. Several support legs 3 are located in the inner cavity of the ring beam 5, and several H-shaped steels 2 and support legs 3 are arranged in a circular array with the top of the supporting top plate 1 as the center. The top surface of the supporting top plate 1 is a circular octagon. The entire structure is arranged in a ring shape with good integrity. There is no need to add diagonal braces on the outside, and the site occupies a small area.

[0024] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 5 ,

[0025] Storage grooves 7 are evenly opened on the front and back sides of the supporting top plate 1, and the opposite sides of the inner cavity of the storage groove 7 are connected to the connecting shaft 8 for rotation. The outer periphery of the connecting shaft 8 is fixedly sleeved with a winding roller 10, and the outer periphery of the winding roller 10 is movably sleeved with a connecting rope 11, and one end of the connecting rope 11 is fixedly installed with a hook 12, and the other end of the connecting rope 11 is fixedly connected to the outer periphery of the winding roller 10. By setting the hook 12 to connect with the external lifting equipment, the overall lifting of the device is convenient.

[0026] A torsion spring 9 is movably provided on the outer periphery of the winding roller 10, and one end of the torsion spring 9 is fixedly connected to the outer periphery of the adjacent winding roller 10, and the other end of the torsion spring 9 is fixedly connected to the inner cavity side wall of the adjacent storage groove 7. By providing the torsion spring 9, the hook 12 can be stored in the inner cavity of the storage groove 7, which can avoid the hook 12 being dragged outside when not in use, affecting the normal use of subsequent devices.

[0027] Working principle: After the annular tooling is completed, first adjust the level of the tooling top surface, and then fix the 8 bottom plates 4 by drilling and planting steel bars to ensure that the tooling is stably connected to the original ground. Place the lower section of the cage on the assembly tooling, weld and make T-shaped plates 6, and make holes in the flanges of the plates. Place the T-shaped plates 6 at the center of each supporting top plate 1, the lower edge of the H-shaped steel 2 and the upper edge of the bottom ring beam 5, and fix them with bolts. After completing the reinforcement of the lower section of the cage, complete the assembly of the upper section of the cage. When the cage needs to be moved away as a whole At this time, pull the hook 12 out of the inner cavity of the storage groove 7, pull out all the connecting ropes 11 wrapped around the winding roller 10, and connect the hook 12 to the external lifting equipment. The operation of the hook 12 on the other side of the supporting top plate 1 is as above and will not be repeated here, which is convenient for transporting the cage. After the lifting is completed, separate the hook 12 from the adjacent lifting equipment, and under the action of the adjacent torsion spring 9, the connecting rope 11 can be wound around the outer periphery of the winding roller 10, which can avoid the hook 12 being dragged outside when not in use, affecting the normal use of subsequent devices.
