Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power installation, and in particular to a transport tool for offshore wind power long tube components and a transport method thereof. Background Art

[0002] In recent years, with the rapid development of marine new energy development, as one of the most large-scale development and commercial development prospects of new energy, the scope of offshore wind power development has gradually expanded from shallow offshore to deep sea. As the water depth of the application sea area continues to deepen, floating wind turbines have replaced traditional fixed wind turbines and become the key equipment for deep-sea wind power development. Traditional deep-sea floating wind turbines generally adopt the method of whole machine towing, that is, the floating foundation is manufactured in the shipyard, the wind turbine is assembled at the shore dock, and then the floating wind turbine foundation is placed in the designated operating sea area by transport ships; then the tower, nacelle, blades and other modules are spliced ​​on the wind turbine foundation by the crane of the offshore installation ship. In this way, the overall towing distance is too far, and there are many sea conditions to deal with, and the towing cost remains high. Therefore, in order to reduce the difficulty and cost of transportation, the current floating wind turbines are also assembled and placed in offshore docks. The floating wind turbines are divided into multiple modules, transported to the designated deployment sea area by transport ships, and the modules are spliced ​​and placed at sea by the crane of the operating ship.

[0003] After the wind turbine modules are disassembled, they are usually laid out in sections in a flat manner for stacking in the offshore dock, and the lifting equipment grabs and lifts them for assembly as needed; this results in the use of available space on the dock deck, increasing the overall cost of the offshore dock. At the same time, the buoys, connecting aisles and wind turbine towers of the wind turbine foundation are all long cylindrical components, which are prone to rolling and other problems during storage, making stacking more difficult and prone to safety hazards. If the fixing device for stacking is increased, it will undoubtedly further increase the cost of the offshore installation ship, and it will be difficult to achieve low-altitude lifting operations of the lifting equipment and miniaturization of the equipment.

[0004] Therefore, how to better stack and transport long cylindrical components such as wind turbine foundation buoys, connecting aisles and wind turbine towers, reduce the area occupied by offshore docks, and reduce the limitations of lifting equipment has become the focus of research and development.

[0034] Compared with the prior art, the present invention has at least the following beneficial effects:

[0035] 1. The wind power long tube transport tooling of the present invention realizes the stacking and assembly transportation of long tube components such as the basic buoy, the basic aisle, and the segmented tower in the vertical direction by setting up a movable transfer component, and utilizes the storage space in the vertical direction to save the available space of the offshore wind power installation platform, reduce the lifting height of the long tube components, and thus reduce the center of gravity height of the lifting equipment; in addition, it can solve the limitation of component stacking and storage in the prior art. Through the linkage cooperation of the transfer component and the placing component, it can complete the operation of stacking the long tube components on the transport rack in sequence, and can also complete the transfer of the long tube components on the transport rack to the assembly station of the transport bottom plate in sequence, which is convenient for the lifting equipment to be lifted;

The overall intelligent transportation method of the transport tooling of the present invention is highly intelligent, and the transportation is flexible, efficient, stable and reliable; specifically, when it is necessary to stack the long-tube components and store them on the transport rack, the empty transfer plate and the receiving plate can be moved to the pick-up and placement station, and then the long-tube components can be placed on the receiving plate in turn by the lifting equipment, and the transfer plate can be driven to move along the transfer slide rail to the lifting bottom plate, and then the lifting bottom plate drives the transfer plate and the receiving plate to transport the long-tube components to the target position;

[0039] When long cylindrical components need to be assembled, the placing plate carrying the long cylindrical components is first driven to move horizontally to the transfer plate of the transfer assembly, and the transfer plate is driven to move downward along the transport back plate by driving the lifting base plate. When it moves to the lifting position of the transport base plate, the transfer plate is driven to move forward along the transfer slide rail to the pick-up and place position for lifting by lifting equipment, making the assembly process more convenient and improving operational efficiency and work safety.
