Description

Technical Field

[0001] The utility model relates to the field of production equipment for wind power towers, in particular to a tower support structure for a wind power generator set. Background Art

[0002] The tower used to support the wind turbine generator set is conical. Due to its huge size, in order to facilitate production and transportation, the tower is usually divided into several sections for production. After the sections are transported to the construction site, welding and assembly operations are carried out. The section is welded by multiple sections using roller frames as supporting tools. Before welding, the axes of the two adjacent sections must be aligned to prevent the wall from tilting, otherwise it will affect the load-bearing capacity of the tower and cause the sections to be scrapped. Therefore, how to ensure the coaxiality between the sections is crucial. At present, when welding conical sections, it is necessary to repeatedly adjust the height of the external support parts, which is a cumbersome process and takes a long time. Utility Model Content
