Description

Technical Field

[0001] This utility model relates to a blade support platform for a wind turbine installation vessel, belonging to the field of auxiliary frame technology. Background Technology

[0002] Currently, the offshore wind power industry is booming in various regions, leading to a surge in demand for wind turbine blade transportation, with transportation distances continuously expanding into deep and far-sea areas. Wind turbine blades are trending towards larger and longer sizes, presenting challenges during transportation such as exceeding size limits, complex road conditions, and significant environmental impact.

[0003] Blade transport fixtures typically need to be customized based on the ship's layout and the number of blades, resulting in poor versatility. Large wind turbine installation vessels have a large deck area and the ability to load wind turbine equipment such as nacelles, tower sections, and blades. However, blade installation occupies a significant amount of space, necessitating efforts to alleviate deck congestion. Utility Model Content

[0004] The purpose of this invention is to provide a blade support platform for a wind turbine installation vessel. It features a modular, detachable structure, allowing for segmented assembly and installation. Major connections are secured with pins, and the lower part is supported on the hull's strong ribs to prevent damage. The assembled platform exhibits excellent strength and meets towing requirements. To accommodate longer blades, the position of the support bracket is flexible and easy to move.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a wind turbine installation vessel blade support platform, including a Bailey bridge, wherein the Bailey bridge includes a frame I, a frame II, an upper crossbeam structure, and a lower crossbeam structure. The frame I, frame II, upper crossbeam structure, and lower crossbeam structure are sequentially connected to form a frame structure. The frame I includes a first layer of strong longitudinal beams, a second layer of strong longitudinal beams, and connecting beams.

[0037] The working principle of one embodiment of this utility model is as follows: This utility model is divided into a left Bailey bridge, a middle Bailey bridge, and a right Bailey bridge, which are composed of two types of frames, namely Frame I 2 and Frame II 3, which are assembled alternately. Frame I 2 includes a single layer of strong longitudinal beams 6 arranged along the width of the ship, a second layer of strong longitudinal beams 7 arranged along the width of the ship, and a connecting beam 8.

There are a total of 4 Frame I 2 frames and a total of 3 Frame II 3 frames.

[0038] The upper transverse beam structure 4 of the Bailey bridge consists of alternating layers of strong transverse beams 11 and 12 at certain intervals, while the lower transverse beam structure 5 consists of two layers of strong transverse beams 13 and 14. Taking the deck connection point as the root, along the ship's beam direction, the upper transverse beam structure 4 is connected at two points near the root by a single layer of strong transverse beams 11, with the remaining connections arranged sequentially in the order of first-layer strong transverse beams 11 and first-layer transverse beams 12. The lower transverse beam structure 5 is furthest from the root by a second-layer transverse beam 14, with the remaining connections being second-layer strong transverse beams 13. All strong transverse beams and strong longitudinal beams form the main structure, with other structures overlapping the main structure.

[0039] The heightening support 15 is located at the top of the Bailey bridge and is divided into left-side heightening support 15, middle heightening support 15, and right-side heightening support 15. Taking the left-side heightening support 15 as an example, each frame structure is similar, consisting of support beams 20, support longitudinal beams 21, and support connecting beams 8.

[0041] The deck connecting lug 22 is located on the side deck, and the Bailey bridge connecting lug 16 is located at the root of the first-layer strong longitudinal beam 6. The two are connected by a pin and serve to fix the Bailey bridge. The Bailey bridge bottom support 17 is located below the root of the Bailey bridge and serves to limit the Bailey bridge. The number of deck connecting lugs 22 and Bailey bridge connecting lugs 16 is the same as that of frame I 2 and frame II 3, and the number of Bailey bridge bottom supports 17 is the same as that of frame I 2.

[0042] The combined blade mounting platform consists of two parts, located on the port and starboard sides of the hull respectively. The port and starboard sides are symmetrically arranged. Each side platform consists of 3 Bailey bridges and 3 additional support brackets, with a total of 19 connection structures on each side.

[0043] To ensure personnel safety and facilitate transportation, the top of the blade placement platform is equipped with removable railings.

[0044] Instructions for installing and using the blade mounting platform: The platform is installed at a strong rib of the hull. First, select a suitable location for the deck connecting lug 22. Then, use a crane to lift the left-side Bailey bridge and assemble it with the hull. Once the top of the Bailey bridge is flush with the deck, insert pins into the lug connections to secure it, ensuring the lower support is flush against the hull plating and strong rib. The middle and right-side Bailey bridges are then assembled and connected sequentially, ensuring proper clearance fit. Repeat the above steps to install the Bailey bridge on the other side of the hull at the same location. Next, install and secure the extension bracket 15 according to the blade transport fixture requirements. Finally, place the transport fixture and blades, and secure them. After assembly, the platform can hold three blades.
