Description

Technical Field

[0001] The utility model relates to the field of offshore wind turbine hoisting tooling, in particular to a high-position supporting tooling for assembling a box transformer in an offshore wind turbine cabin. Background Art

[0002] With the continuous advancement of technology, the capacity of offshore wind turbines has gradually increased, and wind turbine units are also becoming larger. Currently, the nacelle and transformer for wind turbines of 13.6MW, 16MW, and above are externally mounted. After the nacelle and transformer are transported to the installation site, they need to be assembled on-site. Because the transformer is installed at the bottom of the tail, the nacelle must be transferred from the transport tooling to the high-level support tooling to ensure sufficient space for transformer assembly at the installation site.

[0003] Current high-level support fixtures typically utilize a base, large columns, and small columns. The large and small columns are independent of each other, causing misalignment and deformation under the heavy pressure of the cabin. When the cabin and high-level support fixture are connected, the holes in the high-level support fixture and the cabin connection bolts do not align one-to-one. Currently, the small columns are typically pre-assembled. This involves first removing the eight small columns and bolting them to the cabin at regular intervals. The bottom of the small columns is then connected to the large columns. Compared to direct alignment, this pre-assembly method is extremely inefficient and carries the risk of misaligning the small columns. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a high-position support tooling for offshore wind turbine cabin assembly box transformer, which can not only realize the rapid alignment of the cabin and the high-position support tooling, thereby improving construction efficiency, but also avoid the exposure of personnel directly under the cabin during pre-installation of the support, thereby eliminating safety hazards.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A high-position support tooling for an offshore wind turbine cabin assembly box transformer comprises a base, an upper support and a lower support. A foundation plate is installed between the upper and lower supports. The foundation plate is annular and fixed to the upper and lower supports in upper and lower correspondence.

[0007] A Pozidriv support frame is fixed inside the base, and an anti-overturning device is installed outside the base.

[0008] Anti-overturning devices are provided at the front, back, left and right sides of the base. The left and right anti-overturning devices extend outward and are processed into a whole with the base. The front and back anti-overturning devices are detachable brackets, which are connected to the base by bolts.

[0009] A working platform is installed on the upper part of the lower support, and the base plate serves as a guardrail of the working platform; the bottom of the telescopic ladder is fixed on the base, and the top is fixed on the working platform.

[0010] The upper support and the lower support are both composed of multiple columns and are distributed in a ring shape, wherein the columns of the lower support are long and the columns of the upper support are short, and the installation position of the upper support matches the position of the cabin flange.

[0011] The utility model provides a high-position support tooling for offshore wind turbine cabin assembly box transformer, which has the following technical effects:

[0012] 1) By adding a base plate between the large and small columns of the existing high-position support tooling, the stability between the large and small columns can be improved, and the length of the small column can be appropriately shortened to increase its stability and reduce deformation.

[0013] 2) In this application, the small columns and the base plate are a whole during the replacement process to ensure that the relative positions of the small columns remain unchanged, thereby ensuring smooth docking of the small columns with the cabin holes.

[0014] 3) Holes for different machine models are set on the base and base plate, and can be installed at the corresponding holes according to different machine models. This makes it suitable for different machine models and improves adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3As shown, a high-position support tooling for offshore wind turbine cabin assembly box transformer is used on the main deck of the wind power installation platform. This device includes a base 4, a lower support 3, an upper support 1, and a base plate 2 is added between the lower support 3 and the upper support 1. Specifically, the height of the upper support 1 is appropriately shortened, and a circular base plate 2 is added between the lower support 3 and the upper support 1 to enhance the stability between the lower support 3 and the upper support 1. The upper support 1 is fixed to the base plate 2 according to the arrangement position of the cabin connection bolts. When replacing, the base plate 2 and the upper support 1 are disassembled as a whole to ensure that the position of the cabin installation on the upper support 1 remains unchanged.

[0024] Specifically, the lower support 3 is composed of 8 large columns, and the bottoms of the large columns are connected to the base 4.

[0025] The upper support 1 is composed of 8 small columns 1, and the top of the small column 1 is connected to the cabin flange.

[0026] The base plate 2 is a single unit. The top of the base plate 2 secures the upper support 1, while the bottom of the base plate 2 is connected and secured to the lower support 3. Bolts are used to secure the base plate 2 to the upper support 1, the lower support 3, and the upper support 1 to the cabin flange. The base plate 2 has a U-shaped cross-section and incorporates a suitable number of internal ribs to ensure adequate support and enhance stability between the columns.

[0027] In order to solve the problem of inconvenience for personnel after the cabin is docked with the high-position support tooling, a support device 8 is added on the 8 large columns near the top. The support device 8 is a connector made of H-shaped steel. The support device 8 is fixed to the inner wall of the large column and is used to support the work platform 10. The circular work platform 10 is placed on the support device 8. A hole is opened in the center of the work platform 10 for personnel to pass through. The bottom of the telescopic ladder 9 is fixed on the base 4, and the top is fixed on the work platform 10. The telescopic ladder 9 is telescopic and can be extended from the top upward to the inside of the cabin, making it convenient for personnel to enter the cabin.

[0028] After the work platform 10 is installed, the work platform 10 is located at the lower end of the inner circle of the base plate 2, so that the base plate 2 can serve as a guardrail for the high-position support work platform 10 inside the tooling.

[0029] like Figure 4-6 As shown, the telescopic ladder 9 is a pull-out structure, comprising a first ladder 9.1 and a second ladder 9.2. Connecting blocks 9.3 are arranged on the upper and left sides of the second ladder 9.2, and the connecting blocks 9.3 and the second ladder 9.2 are fixed together by bolts. The first ladder 9.1 is slidably mounted on the outside of the connecting blocks 9.3. After the first ladder 9.1 slides up and down relative to the second ladder 9.2, it is fastened by a pin inserted into the side of the connecting block 9.3, and then tightened with a screw on the front of the connecting block 9.3.

[0030] To address the issue of the cabin's center of gravity being too high after docking with the high-level support fixture, anti-tilt devices are installed on the front, rear, left, and right sides of the base 4. Specifically, the left and right anti-tilt devices extend outward and are integrally formed with the base 4. The front and rear anti-tilt devices are detachable brackets 5, which are bolted to the base. These brackets can be added or removed depending on the location of the cabin's center of gravity, thereby increasing the high-level support fixture's anti-tilt capability.

[0031] In addition, if Figure 2 As shown, a 'P' support frame 7 is fixed inside the base 4. The 'P' support frame 7 is used to enhance the stability of the base 4 and increase the contact area between the base 4 and the deck. The bolt holes 6 on the base 4 can adapt to cabins of different sizes.

[0032] like Figure 3 As shown, the working platform 10 is fixed on the supporting device 8 on the top of the lower support 3, the top of the telescopic ladder 9 is fixed to the working platform 10, and the bottom is fixed to the M-shaped support frame 7 for people to go up and down.
