Description

Technical Field

[0001] The utility model relates to the field of wind power tower production, in particular to a segmented tower flange assembly platform. Background Art

[0002] The segmented wind power tower is a new branch in ultra-large onshore wind turbines. Compared with traditional steel towers, it has a greater power generation capacity, and can solve the problems of transportation, construction, and factory building transformation faced in the implementation of large tower projects more economically and effectively through segmented transportation and combined installation, and can popularize and develop wind power resources more efficiently.

[0003] After the segmented tower completes the conventional splicing and welding links, it is necessary to cut the segments to solve the problems of large-diameter production and transportation. Before cutting the segmented tower, it is necessary to first assemble the segmented flanges and then weld them to the tower. Therefore, it is necessary to design a segmented tower flange assembly platform for assembling the segmented flanges.

[0004] The existing assembly platform for segmented tower flanges is as follows: The application date is July 13, 2022, and the application number is CN202221797697.6, which discloses a segmented tower assembly tooling. The electric cylinder drives the segmented flange to slide on the sliding component, so that the segmented flanges are abutted in a circle and then connected through the flange connecting plate, improving the splicing efficiency of the segmented flanges, thereby helping the splicing of the segmented tower. This segmented tower assembly tooling has strict requirements for the placement position of each segmented flange. The middle part of each segmented flange must correspond to the electric cylinder. Since this tooling lacks a positioning mechanism, the implementation difficulty is large. If the middle part of the segmented flange does not correspond to the electric cylinder, the center of the segmented flange will be different from the center of the tooling. After the electric cylinder pulls the segmented flange, the segmented flanges will be misaligned and the connection between the segmented flanges cannot be achieved.

[0005] Based on this, the present application provides a segmented tower flange assembly platform with a positioning function, which is convenient for quickly assembling segmented flanges. Summary of the Utility Model

[0026] Embodiment 1

[0027] This embodiment provides a segmented tower barrel flange assembly platform, as shown in the appendix Figure 1 As shown, it includes a platform body 1 and multiple support beams 2 evenly distributed on the outer periphery of the platform body 1. In this embodiment, it is preferably provided with 6 support beams 2 on the outer periphery of the platform body 1. The platform body 1 is a polygonal or circular platform formed by resistance welding of I-beams, channel steels or square steels, and is provided with 3 to 6 legs 1.1 at its bottom.

[0028] In order to realize the positioning and placement of the segmented flange on the assembly platform, as shown in the appendix Figure 1 and the appendix Figure 2 As shown, in this embodiment, an arc-shaped positioning stop 3 is slidably arranged on each of the support beams 2, and a locking handle 4 for locking its position is arranged on the positioning stop 3. Preferably, as shown in the appendix Figure 2 As shown, the support beam 2 is made of square steel, and slide rails 2.1 are arranged on both sides of the support beam 2. Both sides of the bottom of the positioning stop 3 are provided with sliding sleeves 3.1 slidably connected to the two slide rails 2.1, and the locking handle 4 is arranged on the sliding sleeve 3.1. The stud of the locking handle 4 is threadedly connected to the sliding sleeve. During specific use, the position of the positioning stop on the support beam can be adjusted according to the outer diameter of the tower barrel flange, and then the locking handle is rotated. The position of the positioning stop is locked by using the bolt of the locking handle to press against the slide rail. When the segmented flange 10 is hoisted and placed, its outer arc surface is attached to the positioning stop.

[0029] Preferably, in this embodiment, a scale (not shown in the figure) is arranged on the slide rail 2.1 to facilitate the rapid adjustment of the position of the positioning stop.

[0030] Furthermore, as shown in the appendix Figure 1 As shown, this embodiment also further provides three telescopic inserts 5 arranged at 120°. The thickness of the insert 5.1 is equal to the reserved gap between two segmented flanges, and is used to position the ends of the segmented flanges. Specifically, when placing the segmented flanges, its outer arc surface is attached to the positioning stop, and both ends are attached to the lower part of the insert. In this way, the rapid positioning and placement of the segmented flanges are realized. After being placed in place, the adjacent two segmented flanges are bolted together by using a connecting plate 20.

[0031] Preferably, as shown in the appendix Figure 1 As shown, the telescopic insert 5 of this embodiment includes an insert 5.1 and a cylinder 5.2. The insert 5.1 is fixedly installed on the telescopic rod of the cylinder 5.2, and the insert 5.1 is located in the middle of two support beams 2. The cylinder 5.2 is fixed on the platform body 1.

[0032] Preferably, as shown in the appendix Figure 3 As shown, the bottom of the insert 5.1 does not expose the bottom surface of the segmented flange, and this design does not affect the installation of the connecting plate and the segmented flange.

[0033] Preferably, as shown in the appendix Figure 2As shown, a backing plate 2.2 made of polytetrafluoroethylene is also provided on the top of the supporting beam 2. The low friction of the polytetrafluoroethylene material can be utilized to facilitate the movement of the split flange on the assembly platform and also avoid surface scratches caused by the direct contact between the split flange and the supporting beam.

[0034] It should be noted that: the moving scenario in this embodiment can be: when the position of the positioning stop is larger than the outer diameter of the flange, the gap between the two split flanges is relatively large at this time, which is convenient for the lowering of the split flange. After the split flange is placed, the split flange can be pushed forward so that its two ends abut against the positioning stop, and at the same time, the positioning stop is adjusted to make it contact with the split flange.

[0035] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
