See fig. 1 and 5.
As shown in fig. 1, the present invention provides an offshore wind turbine installation apparatus, which includes an installation platform 1, where the installation platform 1 may be a conventional offshore wind turbine installation platform, such as: a bottom-sitting offshore wind power installation platform, an inserted pile offshore installation platform, and the like. Be provided with the installation tower on this mounting platform 1, this installation tower is including controlling two body of the tower 2, and the installation position is located between two body of the tower 2, is provided with bearing platform 3 in this installation position, and this bearing platform 3 is used for bearing tower section of thick bamboo 4, and this bearing platform 3 can come in and go out in this installation position to can remove on the upper and lower direction of installation position, seted up notch 11 on the mounting platform 1 of installation position bottom, during this notch 11 entering installation positions of fan basis accessible.
The two tower bodies 2 are respectively provided with a limiting device for keeping the tower barrel 4 in the installation position vertical and fixing the tower barrel 4 in the up-down direction. The tower 4 may be a segmented tower 4 or an integral tower 4.
In specific implementation, when the fan is installed, the bearing platform 3 in the installation position is moved out of the installation position, so that the tower barrel 4 is placed on the bearing platform 3, then the tower barrel 4 is erected on the bearing platform 3 through the hoisting device, and then the bearing platform 3 drives the tower barrel 4 to move to the installation position.
When the tower drum 4 is an integral tower drum 4, the tower drum 4 entering the installation position is limited by the limiting device, so that the tower drum 4 is ensured not to deflect, and the tower drum 4 is fixed on the installation platform 1.
When the tower 4 is a sectional tower 4, the tower 4 entering the installation position moves upward under the driving of the bearing platform 3 until the height of the tower 4 is higher than that of one tower 4. Then, the limiting device limits the tower barrel 4, and the tower barrel 4 is fixed in the vertical direction while the tower barrel 4 is ensured not to be inclined, so that the tower barrel 4 does not fall down. Then, the supporting platform 3 is reset, then the supporting platform 3 is moved out of the installation position again, the other tower barrel 4 is erected on the supporting platform 3 by the hoisting device, and then the supporting platform 3 drives the tower barrel 4 to move towards the installation position. The other tower barrel 4 entering the installation position is driven by the supporting platform 3 to move upwards and is aligned with the first tower barrel 4, and then the two tower barrels 4 are spliced together by utilizing manpower. After the two tower drums 4 are spliced together, the limiting device releases the tower drums 4 for limiting. Then the bearing platform 3 drives the spliced tower barrels 4 to move upwards together until the height of the tower barrels 4 is higher than that of one tower barrel.
