Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power generation, in particular to a nacelle hub chassis tooling. Background Art

[0002] Against the backdrop of the depletion of global fossil energy and severe climate change, wind energy has become increasingly strategically valuable as a renewable, clean energy with little environmental impact. All countries attach great importance to wind energy, and large offshore wind farms are a new market industry and have become a rapidly emerging member of clean energy.

[0003] The construction of an offshore wind farm requires the installation of wind turbines at sea. There are two ways to install offshore wind turbines: integral and split installation. Due to the influence of ship equipment, wind farm geology, water depth and other conditions, most offshore wind farm construction currently adopts split installation construction technology. Usually, the installation ship is stationed first, and then the transport ship transports the wind turbine components to the site. After the transport ship docks, it starts to barge the wind turbine components and hoist them. Due to the large size and mass of the wind turbine nacelle hub, it is necessary to assemble the remaining parts of the nacelle hub on the installation ship in advance, and the assembly takes a certain amount of time. The transport ship often waits for the installation ship on site, and the continuity of the construction cannot be guaranteed, which affects the overall construction efficiency. Utility Model Content

By welding and fixing the chassis to the deck of the installation ship, the stability of the chassis tooling can be improved. The adapter assembly is detachably installed above the support assembly. Without disassembling the chassis, the chassis tooling can be adapted to different sizes of nacelle hub bases by replacing the adapter assembly, avoiding damage to the deck caused by frequent replacement, protecting the deck, reducing the time spent on welding, and improving construction efficiency.

[0021] The side wall of the support tube is provided with a through hole, and an electric wire is passed through the through hole. A distribution box is provided in the support tube, and the distribution box is connected with the electric wire to pass the power supply into the interior of the support tube.

[0026] By adopting the above device, the first connection hole on the first flange corresponds to the mounting hole on the top of the support tube, and the adapter assembly is installed on the support tube as a whole through fasteners, so that the adapter assembly and the support tube are tightly connected, and different types of cabin hubs can be dealt with by replacing different types of adapter assemblies, which effectively increases the scope of application of the chassis tooling. During construction, the cabin hub is turned upside down on the chassis tooling, and the cabin hub is installed and fixed through the connection between the second flange and the cabin hub base, and then the remaining parts of the cabin hub are assembled. After the remaining parts of the cabin hub are fully assembled, the connection between the cabin hub base and the second flange is released, and the cabin hub can be hoisted.

[0038] The following is combined with Figure 1-3 This application is described in further detail.

[0039] Example:

[0040] A nacelle hub chassis tooling, such as Figure 1 As shown, it includes a chassis 1, a support assembly 2 and an adapter assembly 3. The chassis 1 is welded to the deck of the installation ship, the support assembly 2 is welded above the chassis 1, and the adapter assembly 3 is detachably installed above the support assembly 2. The adapter assembly 3 is used to connect the engine room hub. Among them, the chassis 1 includes a bottom bracket 11 and a connecting frame 12. The bottom bracket 11 is welded to the deck of the installation ship, which effectively reduces the situation where the installation ship is unstable due to changes in the marine environment and affects the chassis tooling. The connecting frame 12 is welded to the bottom support frame, and the connecting frame 12 is welded to the support assembly 2. The stability and load-bearing capacity of the overall structure of the chassis tooling are ensured by the support frame and the bottom bracket 11.

[0041] like Figure 1-3 As shown, in this embodiment, the support assembly 2 includes a support cylinder 21, and the bottom of the support cylinder 21 is welded to the connecting frame 12, so that the support cylinder 21 is stably fixed on the chassis 1 and has a certain distance from the ground. A manhole 22 is provided at the bottom of the support cylinder 21, and the design of the manhole 22 facilitates the entry and exit of construction personnel, so that construction personnel can enter the support cylinder 21 to assemble the nacelle hub.

[0042] In addition, in order to ensure the safety of construction workers, a barrier 24 is provided near the manhole 22. The barrier 24 plays an isolation and protection role, which can reduce the accidental fall of construction workers during construction and effectively ensure the safety of construction workers. In this embodiment, the barrier 24 can be selected as a safety guardrail or a protective net.

[0043] like Figure 2-3 As shown, in this embodiment, the top surface of the support tube 21 is provided with a plurality of mounting holes 23, which are used to connect with the adapter assembly 3, so as to achieve stable support of the nacelle hub. In addition, a through hole 25 is provided on the side wall of the support tube 21 near the bottom, and a wire 26 is provided through the through hole 25 to introduce an external power source into the support tube 21. A distribution box 27 is provided in the support tube 21, and the wire 26 is connected to the distribution box 27 to provide a stable power supply for the electrical equipment during the assembly process.

[0044] like Figure 1-3As shown, the adapter assembly 3 includes a first flange 31, a second flange 32 and a fastener 33. Among them, a plurality of first connection holes 311 are circumferentially arranged on the first flange 31, and a plurality of second connection holes 321 are circumferentially arranged on the second flange 32. During installation, the first connection hole 311 is aligned with the mounting hole 23 on the top surface of the support tube 21, and the second connection hole 321 is aligned with the mounting hole on the base of the cabin hub. The first flange 31 is connected to the mounting hole 23 on the top surface of the support tube 21 through the fastener 33, and the second flange 32 is connected to the mounting hole on the base of the cabin hub through the fastener 33. In this way, the cabin hub can be stably fixed on the support tube 21, which is convenient for subsequent assembly work. The split design of the adapter assembly 3 not only facilitates assembly and disassembly, but also improves the versatility and flexibility of the tooling. Among them, in this embodiment, the fastener 33 is selected as a tooling bolt.

[0045] In addition, if Figure 1-3 As shown, in order to further enhance the structural stability of the adapter assembly 3, a plurality of reinforcing ribs 34 are further arranged between the first flange 31 and the second flange 32. These reinforcing ribs 34 are arranged circumferentially between the first flange 31 and the second flange 32 to form a spoke-like structure, thereby effectively improving the overall structural strength and load-bearing capacity of the adapter assembly 3.

[0046] Working principle: During construction, the nacelle hub is barged from the transport ship to the chassis tooling of the installation ship, and the nacelle hub base is connected to the second flange 32 through the fastener 33 to fix the nacelle hub on the chassis tooling, which is convenient for the subsequent assembly of the remaining parts. After the assembly is completed, the connection between the nacelle hub base and the second flange 32 is released, and the nacelle hub can be hoisted. At the same time, the nacelle hub of the next wind turbine is arranged to be barged, and the assembly of the remaining parts of the nacelle hub is carried out on the deck of the installation ship in advance, which not only improves the continuity of construction, reduces the situation of the transport ship waiting for the installation ship, but also greatly improves the overall construction efficiency.
