Embodiment

[0032] Embodiment: This embodiment provides a method for installing a fan on a three-legged platform ship, as shown in the attached figure 1 shown, follow the steps below:

[0033] S1. Platform positioning: as attached figure 2 As shown in the figure, the present invention uses a three-legged platform vessel 1 to install the wind turbine. The three-legged platform vessel 1 is provided with a tower hanger 10. When the three-legged platform vessel 1 arrives at the operating wind field, the three-legged platform vessel 1 is moved by a digital positioning system. Preliminary positioning is carried out, and according to the positioning results, the three-legged platform ship 1 is dropped at the anchor position in the downstream direction, and moved to the vicinity of the construction position through the anchor, the construction position is the position of the engineering pile, and the three-legged platform ship The bow and stern of 1 can precisely adjust the position of the thre...

Abstract

The invention discloses a method for installing a fan on a three-legged platform ship, which comprises the following steps: S1, platform positioning: moving and fixing the three-legged platform ship along the downstream direction, adjusting the position of the three-legged platform ship, and positioning the three-legged platform ship; pile legs are lowered, and the three-leg platform ship is jacked; s2, tower drum hoisting, wherein a tower drum and accessory transport ship is carried to the left side or the right side of the three-legged platform ship and is positioned; the connecting bolts are hoisted to an upper platform and fixed, and the tower drums are hoisted to machine positions to be aligned and fastened; s3, hoisting the main engine hub: carrying and positioning the main engine hub transport ship; hoisting the main machine, pre-installing a connecting bolt, and butting and fastening the main machine with the tower drum; the hub is lifted and turned over through the hub mounting lifting appliance, and the hub is rotated to the position near a main machine to be aligned, mounted and fastened; s4, blade hoisting: carrying and positioning a blade transport ship; and the fan blades are hoisted for pre-installation of connecting bolts, single-blade clamps are replaced, the fan blades are hoisted in sequence, the fan blades are rotated to be aligned with a hub, fastening and turning are conducted, and a unit yaws by 180 degrees.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbine installation, in particular to a method for installing a wind turbine on a three-legged platform vessel. Background technique [0002] Split-type fan installation is the main installation method for large-capacity fans in China. It has the characteristics of less resource consumption, high construction efficiency and high safety. [0003] At present, most offshore wind power constructions use four-legged wind turbine installation ships to install wind turbines, but the resources of wind turbine installation ships are scarce and the cost is high. Using a four-legged platform boat to install wind turbines is technically difficult, costly, and not safe enough. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is that the existing four-leg platform installation vessel for fan installation is scarce in resources, and the installation method i...
