Technical Field

[0001] The utility model relates to the technical field of offshore wind turbine hoisting, in particular to an integral hoisting frame for a nacelle hub. Background Art

[0002] In offshore wind power foundation construction and installation projects, the nacelle hub of offshore wind turbines needs to be transported and installed by hoisting due to its large size and mass. During the hoisting process of the nacelle hub, a hoisting frame is needed to connect the nacelle hub and the crane. The hoisting frame can achieve the effect of increasing the effective lifting height, expanding the hoisting range and changing the force direction of the sling in the offshore area with limited working surface, so that the nacelle hub will not shake during the transportation process, ensuring the balance and stability of the nacelle hub.

[0003] The existing hoisting frame is an integrated design. Different hoisting frames need to be replaced during hoisting to cope with the hoisting of nacelle hubs of different sizes and models. Replacing the hoisting frame requires re-disassembly and connection of rigging and hoisting ropes, which makes the adaptability and flexibility of the hoisting frame poor, increases the cumbersome hoisting steps, and reduces construction efficiency.

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] Example:

[0035] An integral hoisting frame for a nacelle hub, such as Figure 1 As shown, it includes a hanger 1, a hanging rope 2, a hanging rope 3 and a connecting component 4. Among them, the hanging rope 2 is connected to the top of the hanger 1, and the hanging rope 2 is used to connect with the main hook of the crane, so as to achieve a stable connection between the hanger 1 and the crane. The bottom of the hanger 1 is connected to the nacelle hub through the hanging rope 3 to ensure the stability of the nacelle hub during the lifting process. In addition, the connecting component 4 is located at both ends of the hanger 1. The connecting component 4 not only enhances the structural strength of the hanger 1, but also provides more connection points for the hanging rope 2 and the hanging rope 3, further improves the safety of lifting, and expands the scope of application of the hanger 1.

[0036] like Figure 2 As shown, in this embodiment, the hanger 1 includes a cabin hanging beam 11, a hub hanging beam 12 and a connecting beam 13. The connecting beam 13 is located between the cabin hanging beam 11 and the hub hanging beam 12. Both ends of the connecting beam 13 are detachably connected to the cabin hanging beam 11 and the hub hanging beam 12 through flange joints.

[0037] During hoisting, the construction workers first select the appropriate nacelle hanging beam 11, hub hanging beam 12 and connecting beam 13 according to the specific size and model of the nacelle hub for assembly to form a complete hanger 1. Subsequently, the hanger 1 is connected to the crane main hook through the hanging rope 2, and the nacelle hub is firmly connected to the bottom of the hanger 1 through the hanging rope 3. During the hoisting process, the crane main hook pulls the hanger 1 through the hanging rope 2, thereby driving the lifting and movement of the nacelle hub. Due to the detachable design of the connecting beam 13, the adaptability and flexibility of the hanger 1 are effectively improved, so that the hanger 1 can easily adapt to nacelle hubs of different sizes and models, thereby greatly simplifying the hoisting steps, reducing the time and resource waste caused by replacing the entire hoisting frame, and improving construction efficiency.

[0038] like Figure 1-3As shown, in this embodiment, ears 111 are provided on both sides of the cabin hanging beam 11, and the ears 111 are used to connect the hanging rope 2, providing suitable hanging points for the hanging rope 2 to correspond to the two hanging points of the cabin. When hanging, the hanging rope 2 is wound around the ears 111, and the cabin hanging beam 11 is lifted in a manner of holding the hanging rope 2. In addition, a connecting seat 121 is welded at the end of the hub hanging beam 12, which is used to connect with the connecting assembly 4 to ensure the stability of the overall structure of the hanger 1.

[0039] like Figure 1-3 As shown, in this embodiment, the connection assembly 4 includes an adjustment member 41 and a plurality of lifting rings 42. The adjustment member 41 is connected to the end connection seat 121 of the hub suspension beam 12 and is used to connect the hanging rope 2, so that the connection between the hanging rope 2 and the hanger 1 is more flexible and convenient to adjust according to actual conditions. The lifting ring 42 is respectively connected to the ear 111 on both sides of the end of the cabin suspension beam 11 and the connection seat 121 at the end of the hub suspension beam 12. During hoisting, the lifting rope 3 passes through the lifting ring 42 to connect the cabin hub with the hanger 1, which is convenient for hoisting the cabin hub.

[0040] like Figure 3 As shown, in this embodiment, the adjusting member 41 includes an ear plate 411 and an adapter 412, wherein the ear plate 411 is hinged to the connecting seat 121 at the end of the hub suspension beam 12 through the adapter 412. The ear plate 411 is in an arc shape, and five holes 411a are provided on the ear plate 411. The holes 411a are used to connect the lifting ring 42. By selecting different holes 411a for connection, the position of the lifting ring 42 can be finely adjusted, thereby better adapting to nacelle hubs of different sizes and weights.

[0041] like Figure 1-3 As shown, in order to control the stability of the nacelle hub during the hoisting process, an anti-sway component 5 is provided on the connecting beam 13 to reduce the shaking or tilting of the nacelle hub during the hoisting process. The anti-sway component 5 includes a mounting seat 51 and a cable wind rope 52, wherein the mounting seat 51 is welded to the connecting beam 13, and one end of the cable wind rope 52 is connected to the mounting seat 51, and the other end is manually controlled to exert its tension when the nacelle hub shakes, and the unbalanced force of the nacelle hub is offset or reduced by the pulling force of the cable wind rope 52, thereby achieving a better balance control effect and ensuring the smooth progress of the hoisting process.

[0042] In addition, if Figure 1-3 As shown, in order to stably place the hanger 1, three supporting legs 6 are welded to the bottom of the hanger 1. These supporting legs 6 can provide stable support when the hanger 1 is placed, ensuring that the hanger 1 can be stably placed in various environments.

[0043] Working principle: Before hoisting, the construction personnel first select the appropriate nacelle hanging beam 11, hub hanging beam 12 and connecting beam 13 according to the specific size and model of the nacelle hub for assembly to form a complete hanger 1. Then, open the rain cover above the nacelle hub, and firmly connect the nacelle hub to the bottom of the hanger 1 through three hanging ropes 3 and hanging rings 42. When connecting the hanging ropes 2, the two hanging ropes 2 are respectively hooked on the ears 111 on both sides of the nacelle hanging beam 11, and another hanging rope 2 is connected to the hanging ring 42 of the ear plate 411, and then the other ends of the three hanging ropes 2 are connected to the main hook of the crane, and the nacelle hub can be hoisted.
