Description

Supporting structure and wind power tower barrel assembly Technical Field The application relates to the technical field of wind power equipment, in particular to a supporting structure and a wind power tower barrel assembly. Background With the change of the energy structure in China, the wind power industry realizes rapid development. Wind towers are an important component in wind power systems for supporting the nacelle and blades of a wind power generator. In order to facilitate transportation and installation, a traditional wind power tower drum generally adopts a multi-section shell ring structure, and flanges are welded at two ends of the shell ring and are used for connection between the shell rings. In order to prevent the flange from deforming, a channel steel is generally selected to support the flange, specifically, two ends of the channel steel are perforated, the channel steel is connected with the flange holes through bolts, and the channel steel is installed at the end part of the flange. However, with the development of wind generating sets to large-scale, the height and diameter of wind power towers are continuously increased, the requirement of flange control deformation cannot be met by traditional channel steel, deformation control position deviation is easy to occur only in a mode of installing the channel steel on the end face of the flange, and the welding seam of the flange and the shell ring is torn. Therefore, a supporting structure is needed to meet the supporting requirement of the large-diameter wind power tower. Disclosure of utility model The embodiment of the application provides a supporting structure and a wind power tower barrel assembly, wherein the supporting structure can support at any position inside the end part of the wind power tower barrel, and the effect of deformation of the end part of the wind power tower barrel is avoided. In a first aspect, an embodiment of the present application provides a support structure applied to a wind power tower, the support structure including: The wind power tower comprises a supporting body, a supporting body and a supporting rod, wherein the supporting body is configured to be arranged in a communication cavity and/or a cylinder section of a communication piece of the wind power tower, and a cavity wall of the communication cavity and an inner wall of the cylinder section form a circumferential inner wall of the wind power tower; The flexible support assembly comprises a first flexible support and a second flexible support, the first flexible support is arranged at the first end of the support main body, and the second flexible support is arranged at the second end of the support main body; When the support main body is arranged in the communication cavity of the communication piece of the wind power tower and/or in the shell ring, the first flexible support piece and the second flexible support piece are both supported on the circumferential inner wall of the wind power tower. According to the support structure provided by the application, the support main body and the flexible support assembly are arranged, and in the length direction of the support main body, the first end of the support main body is connected with the first flexible support piece, and the second end of the support main body is connected with the second flexible support piece. When the support main body is arranged in the wind power tower, the first flexible support piece and the second flexible support piece are supported on the circumferential inner wall of the wind power tower. The diameters of the wind power towers are different, so that the positions of stress concentration in the transportation process are different, and therefore, the positions of the wind power towers, which are required to be subjected to deformation control, are also different. Unlike available support structure capable of acting only on the end of wind power tower, the support structure of the present application has the function of moving the support structure to the inside of the flange, and the support structure is supported in corresponding deformation controlling position based on different diameters of wind power tower and flange, so that the welding seam between the flange and wind power tower is free and the requirement of transporting and supporting wind power tower in great diameter is met. And, through flexible supporting component, bearing structure need not the bolt and can support at the circumference inner wall of wind-powered electricity generation tower section of thick bamboo, and the circumference inner wall flexible contact of support main part and wind-powered electricity generation tower section of thick bamboo to avoid because the support main part and the circumference inner wall rigid contact of wind-powered electricity generation tower section of thick bamboo, the problem that leads to the flange hole to appear mechanical damage, further reduced extra me
