Description

Technical Field

[0001] The utility model relates to the field of wind power equipment, in particular to an assembled supporting structure of a wind power tower flange. Background Art

[0002] Wind turbine tower is one of the key components in wind power generation. It is usually welded by multiple sections and flanges are welded at both ends to form a semi-finished section. After the welding of the sections is completed, the sections are sandblasted, painted and assembled with related accessories to form a finished section. The finished sections are transported to the wind power generation installation site and the sections are connected by flanges. Therefore, whether it is a semi-finished section or a finished section, the flange may be deformed due to its own weight or external force during the production, transportation and storage process. In this way, the quality of the finished section cannot be achieved at the wind turbine installation site, resulting in the inability to smoothly install the high-strength bolts of the flange connection during hoisting. Therefore, end supports are generally used during storage and transportation to ensure that the flange does not deform.

[0003] Patent technology CN201822131495.8 provides a tower support device, which is provided with radially arranged struts in the support base body, and the struts are provided with mounting plates for connecting with the tower. Therefore, when actually used, the support base body is placed on the roller frame to avoid direct contact between the tower and the roller frame and damage to the zinc layer or paint layer of the tower. However, the tower support device has a complex structure, cumbersome installation, inconvenient use, and does not protect the flange at the end of the tower. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembled support structure of a wind power tower flange which can effectively support the cylinder flanges at both ends of the tower.

[0006] Furthermore, two second supporting devices are included, and the second supporting devices are respectively arranged on both sides of the first supporting device.

[0007] Furthermore, the first supporting device and the second supporting device are rod-shaped structures, the two second supporting devices are coaxially arranged, and the first supporting device and the second supporting device are arranged perpendicular to each other.

[0008] Furthermore, the first supporting device includes at least two longitudinal beams, and a cross beam for connecting the longitudinal beams is arranged between the longitudinal beams.

[0009] Furthermore, the first supporting device includes a supporting device connecting seat arranged on the side wall, and the supporting device connecting plate of the second supporting device is detachably connected to the side wall of the first supporting device through the supporting device connecting seat.

[0010] Furthermore, the supporting device connecting plate and the supporting device connecting seat are connected by fastening bolts.

[0011] Furthermore, a gasket is included, and the cylinder flange is arranged between the connecting plate and the gasket, and the gasket is fixedly connected to the cylinder flange by fastening bolts in the connecting plate holes.

[0012] The beneficial effects of the utility model are as follows: first, a system is provided to support the cylinder flange through the first support device and the second support device. When constructing the above support system, the second support device is detachably connected to the first support device through the support device connecting plate of the second support device and the side wall of the first support device, thereby greatly improving the difficulty of the support system during construction and disassembly, allowing the support system to be applied to occasions where the cylinder flange is blocked or inconvenient to be directly fixed, greatly improving the convenience of the support system during use.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1 to 5 Shown is an embodiment of an assembled support structure for a wind turbine tower flange.

[0021] The tower 13 is an existing wind power tower, and the two ends of the tower 13 are welded with the cylinder flange 14 to form a semi-finished cylinder section. The first support device 11 and the second support device 12 on the upper and lower sides of the first support device 11 are mutually perpendicular structures, and the intersection between the first support device 11 and the second support device 12 is arranged in line with the axis of the cylinder flange 14. The two ends of the first support device 11 and one end of the second support device 12 are fixedly provided with a connecting plate 3, and a connecting plate hole 5 is arranged on the connecting plate 3. The size and position of the connecting plate hole 5 and the flange hole of the cylinder flange 14 match each other, so that the connecting plate 3 can be fixedly connected with the cylinder flange 14 through the fastening bolts arranged in the connecting plate hole 5 and the flange hole, thereby realizing stable support for the cylinder flange 14. The other end of the second support device 12 is detachably connected to the support device connection seat 6 of the side wall of the first support device 11 through the support device connection plate 7, so as to facilitate the installation and disassembly between the second support device 12 and the first support device 11. The second support device 12 and the first support device 11 can be disassembled independently, and when disassembly and installation are inconvenient, an installation and disassembly method can be added. For example, when the second support device 12 or the first support device 11 is deformed and thus difficult to disassemble, the above-mentioned independent disassembly method can conveniently realize the disassembly of the second support device 12 and the first support device 11.

[0022] like Figure 2 As shown, the first support device 11 is formed by the intersection of two mutually parallel longitudinal beams 1 and three mutually parallel transverse beams 2, the longitudinal beams 1 and the transverse beams 2 are arranged perpendicular to each other, and the connecting plates 3 are arranged at both ends of the longitudinal beams 1. The middle sections of the longitudinal beams 1 on both sides of the first support device 11 are provided with support device connecting seats 6, which are respectively used to connect with the support device connecting plates 7 of the second support devices 12 on the upper and lower sides. Specifically, fastening bolts can be arranged in the support device connecting plate mounting holes 71 of the support device connecting plates 7 to achieve the above connection.

[0023] like Figure 3As shown, the second supporting device 12 is formed by the intersection of two mutually parallel longitudinal beams 1 and two mutually parallel cross beams 2. The longitudinal beams 1 and cross beams 2 are arranged perpendicular to each other, the connecting plate 3 is arranged at the upper end of the longitudinal beam 1, and the supporting device connecting plate 7 is arranged at the lower end of the longitudinal beam 1.

[0024] Figure 4 and Figure 5 The connection relationship between the longitudinal beam 1 of the first supporting device 11 and the longitudinal beam 1 of the second supporting device 12 and their respective connecting plates 3 is shown, as well as the connection relationship between their respective connecting plates 3 and the cylinder flange 14. The connecting plate 3 is arranged on the cylinder flange 14, and the pad 4 is arranged below the cylinder flange 14. The connecting plate 3, the cylinder flange 14 and the pad 4 are connected by bolts arranged in the connecting plate holes 5, thereby ensuring the stability of the connected structure and preventing the fastening bolts from falling off during transportation.
