DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0041] S1. Crawler Crane Assembly and Positioning: At the dockyard behind the wharf, the auxiliary crawler crane 102 is assembled using a truck crane 101. Subsequently, the auxiliary crawler crane 102 and truck crane 101 work together to assemble the main crawler crane 103. After the crawler cranes are assembled, the main crawler crane 103 and auxiliary crawler crane 102 are moved to a position 2 meters from the gantry crane track at the wharf's front edge, using a roadbed box, according to the wharf's production schedule and the berthing plan for the floating foundation 201.

[0042] S2. Unloading of wind turbine components: The transport vessel 301 carrying wind turbine components is moored to the crawler crane's position. The tower 202, nacelle 203, blades 204, and containers are barged to the pre-planned location on the dock using the main crawler crane 103, auxiliary crawler crane 102, and truck crane 101. The position of the transport vessel 301 is adjusted as needed during the process. After all barges are completed, the transport vessel 301 is unmoored and departs.

[0043] S3. Berthing of the floating foundation 201: After the transport vessel 301 unties and leaves the dock, the floating foundation 201 slowly berths to the dock with the cooperation of three tugboats. During this process, the center position of the wind turbine installation column must be controlled to be aligned with the center of the main crawler crane 103;

[0044] S4. Tower 202 Installation: The floating foundation 201 is docked. The main crawler crane 103 is connected to the upper flange lifting device of the tower 202, and the auxiliary crawler crane 102 is connected to the lower flange lifting device of the tower 202. The tower 202 is then turned over by lifting. After the turning is complete, the lower flange lifting device of the tower 202 is released, and the main crawler crane 103 slowly lifts the tower 202 and installs it on the wind turbine column of the floating foundation 201.

[0045] S5. Level adjustment: After the tower 202 is installed, the flange lifting device on the tower 202 is removed, and the ballast water of the floating foundation 201 is adjusted to ensure that its level meets the requirements of the next stage of lifting;

[0046] S6. Nacelle 203 Installation: After the top tower 202 is loaded, the main crawler crane 103 lifts the nacelle 203 lifting rigging to the top of the nacelle 203, connects the nacelle 203 lifting rigging shackle to the nacelle 203, and installs the guy rope. The main crawler crane 103 lifts the nacelle 203 to the top of the tower 202 to complete the installation;

[0047] S7. Leveling adjustment: After the nacelle 203 is hoisted, slowly unload the force and adjust the ballast water of the floating foundation 201 to ensure that its levelness meets the requirements for hoisting the wind rotor;

[0048] S8. Wind rotor assembly: After the blades 204 are in place, the auxiliary crawler crane 102 and three truck cranes 101 are used to assemble the blades 204 to the hub 205. The first and second blades 204 are assembled using the same method, using two truck cranes 101 to lift them. After assembly, the lifting points at the blade root are released, while the truck cranes 101 maintain the load on the blade tip. The third blade 204 is assembled using the auxiliary crawler crane 102 and the truck crane 101. After assembly, all crane lifting points are released.

[0049] S9. Wind rotor hoisting: The main crawler crane 103 and the mobile crane 101 work together to lift the rotor horizontally. When the rotor is 2 meters above the ground, the main crawler crane 103 continues to lift, while the mobile crane 101 controls the distance between the blade tip and the ground until the rotor is turned over. After the turning is completed, the auxiliary lifting points of the rotor are released, and the boom of the main crawler crane 103 is rotated to complete the alignment of the rotor and the main shaft.

[0050] S10. Leveling adjustment: After the wind rotor is hoisted, slowly unload the force and adjust the ballast water of the floating foundation 201 to ensure that its loading condition meets the towing requirements of the next stage;

[0051] The present invention utilizes a main crawler crane 103, an auxiliary crawler crane 102, and a truck crane 101 to coordinately complete the assembly of a wind turbine unit and a floating platform at a coastal wharf, thereby alleviating the pressure on the scarce resources of self-elevating wind turbine installation vessels in deepwater areas and effectively reducing cost investment. In addition, the floating foundation 201 is less affected by wind speed, waves, and current speed in the harbor, greatly reducing the difficulty of aligning and installing the wind turbine unit and providing high safety. Furthermore, the advantage of the wharf yard area is fully utilized, and the truck crane 101 is used in advance to complete the assembly of the wind rotor, thereby significantly shortening the construction period and reducing costs.
