Description

Technical Field

[0001] The utility model relates to the field of wind power equipment, in particular to a supporting structure of a cylinder flange of a wind power tower. 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 a support structure for the cylinder flange of a wind power tower which can effectively support the cylinder flanges at both ends of the tower.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the support structure of the cylinder flange of the wind power tower includes a cylindrical tower, and the edges of the two end portions of the tower are provided with cylinder flanges; it includes a tower support device for supporting and protecting the tower, and the tower support device is arranged at the two end portions of the tower, and the tower support device includes a first support device and a second support device arranged in an intersecting manner, and both ends of the first support device and the second support device are fixedly provided with connecting plates, and the connecting plates are provided with connecting plate holes matching the flange holes of the cylinder flange, and the two ends of the first support device and the second support device are fixedly connected to the cylinder flange by fastening bolts in the connecting plate holes.

[0006] Furthermore, the first supporting device and the second supporting device are rod-shaped structures, and the first supporting device and the second supporting device are arranged perpendicular to each other.

[0007] Furthermore, the first supporting device includes at least one longitudinal beam, and the connecting plates at both ends of the first supporting device are arranged on the bottom edge of the longitudinal beam.

[0008] Furthermore, the first supporting device has two longitudinal beams, and a cross beam is arranged between the longitudinal beams to connect the longitudinal beams.

[0009] Furthermore, the second supporting device includes at least one longitudinal beam, the connecting plates at both ends of the second supporting device are arranged on the top edge of the longitudinal beam, and the first supporting device is arranged in the direction of the second supporting device toward the outside of the tower.

[0010] Furthermore, the second supporting device has two longitudinal beams, and a cross beam is arranged between the longitudinal beams to connect the longitudinal beams.

[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] Furthermore, the intersection point between the first supporting device and the second supporting device is arranged colinearly with the axis of the cylinder flange.

[0013] The beneficial effect of the utility model is that in actual use, the connecting plates at both ends of the first supporting device and the second supporting device arranged to intersect are fixedly arranged on the cylinder flange, respectively providing supporting force for the cylinder flange in two straight directions, and the supporting force can provide reverse supporting force when the cylinder flange is subjected to external force, thereby preventing the cylinder flange from being deformed. The utility model is particularly suitable for the transportation of wind power towers. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 5 The figure shows an embodiment of the support structure of the cylinder flange of the wind turbine tower. The tower 13 is an existing wind turbine tower, and cylinder flanges 14 are welded to both ends of the tower 13 to form a semi-finished cylinder section. The first support device 11 and the second support device 12 are mutually perpendicular structures, and the intersection between the first support device 11 and the second support device 12 is arranged colinearly with the axis of the cylinder flange 14. Connecting plates 3 are fixedly arranged at both ends of the first support device 11 and the second support device 12. Connecting plate holes 5 are arranged on the connecting plate 3, and the size and position of the connecting plate holes 5 and the flange holes of the cylinder flange 14 match each other, so that the connecting plate 3 can be fixedly connected to the cylinder flange 14 through the fastening bolts arranged in the connecting plate holes 5 and the flange holes, thereby realizing stable support for the cylinder flange 14.

[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 transverse beams 2 are arranged perpendicular to each other, and the connecting plates 3 are arranged at both ends of the longitudinal beams 1. Figure 3 As shown, the second supporting device 12 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.

[0023] Figure 4 In the embodiment, the connecting plate 3 at the end of the second supporting device 12 is arranged on the top edge of the longitudinal beam 1. Figure 5 In the figure, the connecting plates 3 at both ends of the first support device 11 are arranged on the bottom edge of its longitudinal beam 1. Such a structural design allows the longitudinal beam 1 of the first support device 11 and the longitudinal beam 1 of the second support device 12 to have a spatial misalignment at their intersection when they are arranged in an intersecting manner, thereby ensuring that the two cannot be arranged due to interference. The reason for this design is that all the connecting plates 3 are located in the same plane as the plane where the cylinder flange 14 is located, so it is necessary to perform spatial misalignment processing on the longitudinal beam 1 of the first support device 11 and the longitudinal beam 1 of the second support device 12, which are the overall rod-shaped structures, in order to ensure the realization of the above-mentioned fixed structure. In this embodiment, the first support device 11 is arranged in the direction of the second support device 12 toward the outside of the tower 13, thereby achieving a spatial misalignment arrangement.

[0024] Figure 4 and Figure 5In the embodiment, when the cylinder flange 14 at the end of the tower 13 is fixedly connected to the connecting plate 3, a pad 4 is preferably added. The cylinder flange 14 is arranged between the connecting plate 3 and the pad 4, and the pad 4 is fixedly connected to the cylinder flange 14 by the fastening bolts in the connecting plate holes 5, thereby ensuring the stability of the structure after connection and preventing the fastening bolts from falling off during transportation.
