Description

Technical Field

[0001] The utility model relates to the field of offshore wind power, in particular to a vertical assembly device for offshore wind power pipe racks. Background Art

[0002] The jacket structure in offshore deepwater areas has become the preferred foundation for offshore wind power. Conventional three-leg jacket structures are constructed horizontally and assembled horizontally.

[0003] However, the existing horizontal construction and splicing method has several major disadvantages. First, the horizontal construction and splicing method occupies a large area and has a complicated assembly process: the horizontal construction and splicing method requires a larger site to accommodate single-piece pre-assembly and final assembly, which increases the site occupation cost and may limit the flexibility of the production line; second, the assembly time is long, and the horizontal construction and splicing method requires a lot of time to set up scaffolding between the conductor racks. The scaffolding is relatively large, and the assembly process is complicated, which wastes a lot of manpower and material resources. At the same time, the horizontal conductor rack needs to be hoisted and turned over, and the hoisting and turning process takes at least two days to complete, further increasing the overall construction time; third, the positioning of the conductor rack is difficult during the assembly process, and it is difficult to achieve precise positioning. The conductor rack needs to be adjusted many times, which prolongs the assembly time. Utility Model Content

[0004] The utility model provides a vertical assembly device for offshore wind power conductor frames, which solves the problems that horizontal construction and assembly occupy a large area; the assembly time is long, and a large number of scaffolds need to be set up, and the conductor frames need to be hoisted and turned over; and the positioning process during the assembly of the conductor frames is difficult, and it is difficult to achieve accurate positioning.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a vertical assembly device for an offshore wind power conductor frame, including a conductor frame, a triangular bracket is provided in the middle of the conductor frame, the triangular bracket includes multiple protruding platforms, and a positioning device is provided on the protruding platforms.

The transverse movement device includes a connecting plate, the lifting device is installed on the connecting plate, and the lifting device includes a second hydraulic cylinder, and one end of the second hydraulic cylinder is connected to the arc guide ring.

[0006] In a preferred embodiment, the catheter rack includes a plurality of catheter segments, each of which includes three rack pipes, and a bottom column is provided at the bottom of the rack pipes.

[0010] In a preferred embodiment, the lifting device includes a guide rod and a first hydraulic cylinder, and the guide rod and the first hydraulic cylinder are both mounted on the connecting plate.

[0011] In a preferred embodiment, a mounting plate is provided on the top of the first hydraulic cylinder, a through hole is provided on the mounting plate, the guide rod rests on the through hole, and the second hydraulic cylinder is provided on the mounting plate.

[0012] In the preferred embodiment, a plurality of deflector wheels are provided on the arc-shaped guide ring, the deflector wheels abut against the frame pipe or the steel pipe, and a ladder cage is provided in the middle of the triangular bracket.

[0015] After the jacket is hoisted, the triangular support eliminates the need for scaffolding during assembly, simplifying the assembly process. The multiple extended platforms decrease in length from bottom to top, maintaining the same height. This ensures the triangular support conforms to the jacket's external structure, preventing collisions during jacket assembly.

[0016] Drive multiple second hydraulic cylinders so that multiple arc-shaped guide rings can slowly rest on the conduit segment, so that the conduit segment swings to adjust the vertical position of the conduit segment. When multiple arc-shaped guide rings rest on the conduit segment, the center of the conduit segment is positioned so that the vertical positioning of the conduit segment is accurate. Drive the steering device to rotate the conduit segment in a circle to adjust the horizontal circumferential position of the conduit segment so that the circumferential position is accurately positioned. When the vertical position and circumferential position of the upper conduit segment are aligned with the bottom conduit segment, the first hydraulic cylinder is retracted while lowering the conduit segment so that the conduit segment and the multiple arc-shaped guide rings move synchronously so that the upper conduit segment is aligned with the bottom conduit segment and connected. The overall structure can achieve precise positioning, avoiding the need for multiple adjustments during the conduit rack hoisting process, thereby extending the assembly time of the overall structure.

DETAILED DESCRIPTION

[0028] Example 1:

[0029] like Figure 1-9In the invention, a vertical assembly device for offshore wind power conductor frames includes a conductor frame 1, a triangular support 2 is provided in the middle of the conductor frame 1, the triangular support 2 includes multiple protruding platforms 201, and a positioning device 5 is provided on the protruding platforms 201. The positioning device 5 includes a steering device 6, a transverse movement device 7, a lifting device 8 and an arc guide ring 9. The transverse movement device 7 includes a connecting plate 705, and the lifting device 8 is installed on the connecting plate 705. The lifting device 8 includes a second hydraulic cylinder 804, and one end of the second hydraulic cylinder 804 is connected to the arc guide ring 9. With this structure, the present device vertically installs the conductor frame 1 through the triangular support 2 and the positioning device 5. Compared with the horizontal construction and horizontal splicing method, the space required at the bottom of the vertical installation is smaller. The present device can save a lot of space. The vertical installation does not require hoisting and turning over. After the splicing is completed, the triangular support 2 can be directly hoisted out for use.

[0030] The triangular bracket 2 and the positioning device 5 left after the triangular bracket 2 is hoisted out can be directly reused, which is highly efficient. The triangular bracket 2 and the positioning device 5 left do not need to be disassembled and reassembled, and can be directly used to assemble other jackets 1, which greatly speeds up the assembly time of multiple jackets 1 and saves a lot of manpower and material resources.

[0031] After the jacket 1 is hoisted, the triangular support 2 simplifies the assembly process by eliminating the need for scaffolding during assembly. The multiple extended platforms 201 decrease in length from bottom to top and maintain the same height, ensuring that the triangular support 2 conforms to the jacket 1's external structure and prevents collisions during assembly.

[0032] The multiple second hydraulic cylinders 804 are driven to allow the multiple curved guide rings 9 to slowly rest against the conduit segment 101, causing the conduit segment 101 to swing and adjust its vertical position. When the multiple curved guide rings 9 all rest against the conduit segment 101, the conduit segment 101 is centered, ensuring precise vertical positioning of the conduit segment 101. The steering device 6 is driven to cause the conduit segment 101 to rotate circumferentially, adjusting the horizontal circumferential position of the conduit segment 101 to ensure precise circumferential positioning. When the upper conduit segment 101 is aligned with the lower conduit segment 101 in both vertical and circumferential positions, the first hydraulic cylinder 802 is retracted while the conduit segment 101 is lowered, causing the conduit segment 101 to move synchronously with the multiple curved guide rings 9, aligning and connecting the upper conduit segment 101 with the lower conduit segment 101. The overall structure can achieve precise positioning, avoiding the need for multiple adjustments during the installation of the conduit rack 1, which would otherwise extend the assembly time of the overall structure.

[0033] In the preferred embodiment, the jacket 1 comprises a plurality of jacket segments 101, each of which comprises three jacket pipes 103, with a base column 102 disposed at the bottom of each jacket pipe 103. Thus, the jacket 1 of the present application is a three-legged structure. The triangular support 2 is a triangular structure.

[0034] In the preferred embodiment, the lengths of the multiple protruding platforms 201 decrease from bottom to top. As a result, the triangular support 2 has a triangular structure, and the lengths of the multiple protruding platforms 201 decrease from bottom to top. The multiple protruding platforms 201 have the same height, so that the triangular support 2 structure can adapt to the outer structure of the jacket 1, and the jacket 1 will not collide with the triangular support 2 during assembly.

[0035] In the preferred embodiment, the steering device 6 includes a base plate 601, on which are mounted a rotating shaft 605 and a first motor 603. The rotating shaft 605 is equipped with a gear ring 602, and the first motor 603 is equipped with a gear 604. The gear 604 meshes with the gear ring 602, and the rotating shaft 605 is rotationally connected to the transverse movement device 7. With this structure, the first motor 603 of the steering device 6 is driven to rotate the gear 604, which in turn rotates the gear ring 602, which in turn rotates the rotating shaft 605, which in turn rotates the conduit segment 101 in a circular manner, thereby adjusting the horizontal circumferential position of the conduit segment 101 and ensuring precise circumferential positioning. This prevents inaccurate alignment between the upper and lower conduit segments 101, which could lead to poor stability and insufficient load-bearing capacity of the conduit frame 1.

[0036] In the preferred embodiment, the transverse movement device 7 includes a second motor 701 and a slide rail 703. The second motor 701 is equipped with a screw rod 702, and the slide rail 703 is equipped with a sliding block 704. The block 704 has a threaded hole and is threadedly connected to the screw rod 702. The block 704 is also equipped with a connecting plate 705. With this structure, the second motor 701 of the transverse movement device 7 is driven to rotate the screw rod 702, which in turn slides the block 704, extending the lifting device 8 and the curved guide ring 9. When the jacket 1 is assembled and needs to be lifted, all transverse movement devices 7 are retracted to prevent the positioning device 5 from colliding with the jacket 1.

[0037] In the preferred embodiment, the lifting device 8 includes a guide rod 801 and a first hydraulic cylinder 802, both of which are mounted on the connecting plate 705. With this structure, the first hydraulic cylinder 802 of the lifting device 8 is driven to raise the mounting plate 803 to its highest point, lowering the conduit segment 101 while simultaneously retracting the first hydraulic cylinder 802. This causes the conduit segment 101 to move synchronously with the multiple arcuate guide rings 9, aligning and connecting the upper conduit segment 101 with the lower conduit segment 101.

[0038] In the preferred embodiment, a mounting plate 803 is provided on the top of the first hydraulic cylinder 802 . A through hole is provided on the mounting plate 803 , and the guide rod 801 rests on the through hole. A second hydraulic cylinder 804 is provided on the mounting plate 803 .

[0039] In the preferred embodiment, the arc-shaped guide ring 9 is equipped with multiple deflector wheels 901, which abut against the frame pipe 103 or the steel pipe 301. A ladder cage 4 is provided in the center of the triangular support 2. With this structure, workers use the ladder cage 4 to climb onto the triangular support 2 to weld between two duct segments 101 or between the extension platform 201 and a duct segment 101, while also climbing onto the triangular support 2 via the ladder cage 4 to install the positioning device 5.

[0040] Example 2: Further described in conjunction with Example 1: A construction method for an outdoor auxiliary assembly device for an offshore wind turbine jacket, characterized in that: a ladder cage 4 is lifted by a crane, and then a triangular support 2 is lifted, the triangular support 2 passes through the ladder cage 4, and the position of the bottom column 102 is measured by the position of the ladder cage 4, and the bottom column 102 at the bottom of the jacket 1 is installed;

[0041] Manually climb up the ladder cage 4 to the extended platform 201 to install the positioning device 5, retract the positioning device 5, and use the crane to lift the bottom conduit segment 101 to the outside of the triangular support 2;

[0042] Rotate the steering devices 6 on the multiple positioning devices 5 to align the arc-shaped guide ring 9 with the frame tube 103, and drive the shifting device 7 to extend the arc-shaped guide ring 9;

[0043] Slowly extend the first hydraulic cylinder 802 and the second hydraulic cylinder 804 of the plurality of positioning devices 5 so that the arc-shaped guide ring 9 abuts against the frame pipe 103 and the center of the pipe segment 101 coincides with the center of the triangular support 2;

[0044] Drive the steering device 6 to rotate the conduit segment 101 until the rack pipe 103 is aligned with the triangular support 2 and the circumferential position of the bottom conduit segment 101 is aligned. The crane lowers the conduit segment 101 and drives the lifting device 8 to synchronously lower the positioning device 5 and the conduit segment 101. The bottom conduit segment 101 is connected to the bottom column 102.

[0045] Repeat the above steps until the installation of the catheter frame 1 and the tripod support 2 is completed.
