Description

Reducing type arc tower barrel tool

Technical Field

The utility model relates to the technical field of fan tower construction tools, in particular to a variable-diameter arc tower tool.

Background

In recent years, the development of offshore wind turbines is continuously tending to be large-sized, and extensions of more than 8MW models are gradually favored by more owners, which means that the existing solid tower storage tool cannot meet the development requirement of the large-model tower. For example, the maximum diameter of a tower of the 8.5MW semi-direct-drive type electric fan at sea is 7.5m, and the minimum diameter of the tower is 5m; the maximum diameter of the tower cylinder of the eastern electric 9MW direct-drive fan is 8.5m, and the minimum diameter of the tower cylinder is 5.4m; as can be seen, with the gradual development of the large-sized fans, the diameter maximum difference of the tower is also larger and larger;

The wind turbine tower is generally formed by butt joint of 3-4 sections of segmented towers through flanges, and the service life of the wind turbine tower is influenced by the deviation of ovality of the flanges, so that the wind turbine tower is extremely critical to the safety operation of a subsequent wind turbine generator set. However, due to the influence of the dead weight and the like, the flange ovality inevitably deviates; therefore, compatibility between the tower and the storage/transportation tool becomes a key factor influencing the deformation degree of the tower, and the larger the compatibility of the storage/transportation tool is, the smaller the deformation rate of the tower is. However, most of existing tower storage tools provided by fan installation ships or fan manufacturers are fixed in specification, and are difficult to completely meet the storage/transportation requirements of towers with different specifications, so that the towers are easy to deform in the storage/transportation process, and the economic benefit of the fan installation ships is limited. Therefore, in order to improve the compatibility between the high-power wind turbine tower and the storage/transportation tool, it is necessary to design a storage/transportation tool which is suitable for the high-power wind turbine tower and can be used for reducing and adjusting according to the size of the tower.
