Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technical field of wind power equipment, especially relates to a foldable tower cylinder Chinese character type support. BACKGROUND

[0002] The wind power tower cylinder is the key equipment in the wind driven generator, the cylinder is spliced by the flange, the cylinder group is welded, and then is sandblasted, painted and matched with the related accessory parts to form the finished cylinder segment, and the finished cylinder segment is transported to the wind driven generator installation site to be connected by the bolt between the flanges to form the whole wind power tower cylinder.

[0003] Therefore, whether it is the semi-finished cylinder segment or the finished cylinder segment, the flange may be deformed due to the self weight or the external force in the manufacturing, transportation and storage process, so that the interconnection of the finished cylinder segment cannot be realized at the wind driven generator installation site, the bolt cannot be smoothly installed, and therefore the Chinese character type support is generally installed at the flanges of the two ends in the storage and transportation process to ensure that the flange is not deformed.

[0004] The patent with the application number CN201621206899.3 discloses a tower cylinder flange round steel Chinese character type support, which comprises a plurality of support flange pull rods, the plurality of pull rods are staggered at the flange center position, and the two ends of the pull rod are fixed with the flange holes at the two ends of the flange through the fixing mechanism.

[0005] The patent with the application number CN202120189163.4 discloses a wind power tower cylinder flange support device, which comprises a center connecting plate, a reinforcing ring and support pieces uniformly arranged around the center connecting plate, the end portion of the support piece abuts against the wind power tower cylinder flange, and the support piece is arranged on the reinforcing ring.

[0006] The patent with the application number CN202122878467.4 discloses a universal flange anti-deformation Chinese character type support tool, which comprises a support plate and a reinforcing piece, six circumferentially distributed support rods are connected to the support plate, the support plate and the six support rods form a Chinese character type mechanism, the reinforcing piece comprises a reinforcing plate and six reinforcing rods, the six reinforcing rods are fixed under the reinforcing plate in a circumferential distribution, the reinforcing rods are opposite to the support rods in direction, and the reinforcing rods and the corresponding support rods are connected together.

[0007] That is, the existing Chinese character type support comprises a center connecting plate and N pull rods uniformly distributed on the upper side of the center connecting plate, the pull rods are arranged along the radial direction of the center connecting plate and the outer ends of the pull rods can be detachably connected with the flange of the tower cylinder.

[0008] The existing rice-shaped support is in the form of integral welding with the maximum size of about 5 meters. After the tower drum is transported to the site, it is difficult to recycle due to the large size, and can only be cut and disassembled on site as scrap steel or removed on site. Patent No. CN201220626391.4 discloses a detachable rice-shaped support device, which comprises an adapter plate, a channel steel I, a channel steel II and a channel steel III. The adapter plate and the channel steel I are fixedly connected by bolts and are fixed on the flange of the tower drum. The channel steel II and the channel steel III are fixedly connected with the flange of the tower drum through corresponding holes by bolts. The channel steel I, the channel steel II and the channel steel III are No. 10 channel steels.

[0009] However, the installation position of the wind tower drum is relatively biased, and the installation position may be poor (such as on a mountain, the installation position is relatively narrow), and the rice-shaped support may not be convenient to disassemble and operate. In addition, the disassembly and installation of the rice-shaped support also consumes time and effort, and may also require special tools. Practical new type content
