Description

Technical Field

[0001] This application belongs to the field of hoisting and transportation, and specifically relates to a hoisting and flipping auxiliary component that can be used for blade supports. Background Technology

[0002] With the development of the wind power industry, offshore wind turbines are becoming larger and larger, and the size and length of wind turbine blades are also getting bigger and longer. This poses a great challenge to the sea transportation of the blades. Currently, brackets are usually used to fix the wind turbine blades on the deck of cargo ships.

[0003] The support structure used to support multiple wind turbine blades is large in size and long in length after being combined and connected together. When such a blade support structure is hoisted onto the deck of a cargo ship, horizontal hoisting is unstable and poses a high risk. Vertical hoisting is required. After vertical hoisting, the blade support structure needs to be flipped over so that it lies horizontally on the deck. Before this utility model was made, the above-mentioned vertical hoisting and flipping methods were inconvenient. Utility Model Content

[0004] To facilitate the vertical lifting and flipping of long blade supports, this utility model provides a lifting and flipping auxiliary component for blade supports, which includes a frame, a first lifting hole plate, a second lifting hole plate, a third lifting hole plate, a connecting hole plate, a first flipping lug, and a second flipping lug.

[0005] The frame has a first hoisting hole plate fixedly connected to each of the four corners of one side, and a second hoisting hole plate fixedly connected to each of the two opposite sides. A third hoisting hole plate is also provided next to the first hoisting hole plate. The third hoisting hole plate is fixedly connected to the corresponding side of the frame by protrusions. Each hoisting hole plate can be used to connect with the shackle of the sling.

[0006] Connecting hole plates are fixedly connected to the four corners of the other side of the frame, and a first flipping lug is fixedly connected to the middle of one side. A second flipping lug is fixedly connected to the side of the frame near the first flipping lug. There are two second flipping lugs on both sides of the first flipping lug. Each connecting hole plate is used to fix the hoisting flipping auxiliary component and the blade bracket by means of a pin. Each flipping lug is used to connect with the pull rope.

[0007] Furthermore, a binding hole plate is fixedly connected to the side of the frame. There are two binding hole plates arranged opposite each other. Multiple rope holes are opened on the binding hole plate. Because the weight of the entire blade support is very heavy, multiple ropes are passed through the rope holes of the binding hole plate to bind the lifting and turning auxiliary component and the blade support together, which can prevent the column pin from breaking during lifting.

[0008] The working principle of the above-mentioned hoisting and tilting auxiliary components is as follows:

[0009] The hoisting and turning auxiliary component and one end face of the blade support are fixedly connected together by connecting the orifice plate and the pin. Multiple ropes are then passed through the rope holes of the binding orifice plate to bind the hoisting and turning auxiliary component and the blade support together. Because the entire blade support is very heavy, this can prevent the pin from breaking during hoisting.

[0010] The lifting orifice plates of the lifting and turning auxiliary components are used to connect with the shackles of the slings. The first, second, and third lifting orifice plates at different positions allow the slings to be connected according to the center of gravity of the blade support, so as to adjust the center of gravity of the blade support and make it more stable when it is lifted vertically.

[0011] Once the blade support is vertically hoisted onto the deck of the cargo ship, the first and second tilting lugs of the hoisting and tilting auxiliary component are pre-connected with ropes. Workers can then pull the blade support using these ropes, and the slings above will slowly release, eventually tilting it horizontally onto the deck. The first tilting lug and the two second tilting lugs located on one side of the frame can form a triangular point, serving as the force point for the tilting and pulling action. This ensures that the hoisting and tilting auxiliary component is subjected to uniform and stable force, preventing the blade support from tipping over.

[0012] The aforementioned hoisting and flipping auxiliary components facilitate the vertical hoisting and flipping of the blade support.

[0013] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0014] The lifting and turning auxiliary component for blade supports described in this application, through the design of structural components such as a frame, a first lifting perforated plate, a second lifting perforated plate, a third lifting perforated plate, a connecting perforated plate, a first turning lug, and a second turning lug, facilitates the vertical lifting and turning of the blade support. The lifting perforated plates at different positions allow the lifting slings to adjust the center of gravity of the blade support by selectively connecting them, making the vertical lifting more stable. The first turning lug and the two second turning lugs located on one side of the frame can form a triangular point, serving as the force point for the turning and pulling, which can make the lifting and turning auxiliary component bear force evenly and stably, preventing the blade support from tipping over.

[0022] refer to Figure 1 A lifting and turning auxiliary component that can be used for blade support 200 includes a frame 1, a first lifting hole plate 11, a second lifting hole plate 12, a third lifting hole plate 13, a connecting hole plate 4, a first turning lug 21, and a second turning lug 22.

[0023] A first hoisting hole plate 11 is fixedly connected to the four corners of one side of the frame 1, and a second hoisting hole plate 12 is fixedly connected to the two opposite sides. A third hoisting hole plate 13 is also provided next to the first hoisting hole plate 11. The third hoisting hole plate 13 is fixedly connected to the corresponding side of the frame 1 through a protrusion 2. Each hoisting hole plate can be used to connect with the shackle of the sling.

[0024] The four corners of the other side of the frame 1 are fixedly connected with connecting hole plates 4, and the middle of one side is fixedly connected with a first flipping lug 21. The frame 1 is fixedly connected with a second flipping lug 22 on the side near the first flipping lug 21. There are two second flipping lugs 22 respectively located on both sides of the first flipping lug 21. Each connecting hole plate 4 is used to fix the hoisting flipping auxiliary component 100 and the blade support 200 through a pin. Each flipping lug is used to connect with the pull rope.

[0025] The frame 1 is also fixedly connected to a binding hole plate 3. There are two binding hole plates 3 arranged opposite to each other. Multiple rope holes are opened on the binding hole plate 3. Because the entire blade support 200 is very heavy, multiple ropes are passed through the rope holes of the binding hole plate 3 to bind the lifting and turning auxiliary component 100 and the blade support 200 together, which can prevent the column pin from breaking during lifting.

[0026] The working principle of the above-mentioned hoisting and tilting auxiliary components is as follows:

[0027] Reference Figure 3 The hoisting and turning auxiliary component 100 and the blade support 200 are fixedly connected together by connecting the connecting plate 4 and the pin. Multiple ropes are then passed through the rope holes of the binding plate 3 to bind the hoisting and turning auxiliary component 100 and the blade support 200 together. Since the entire blade support 200 is very heavy, this can prevent the pin from breaking during hoisting.

[0028] The lifting orifice plates of the lifting and turning auxiliary component 100 are used to connect with the shackles of the slings. The first lifting orifice plate 11, the second lifting orifice plate 12, and the third lifting orifice plate 13 at different positions allow the slings to be connected according to the center of gravity of the blade support 200, thereby adjusting the center of gravity position of the blade support 200 so that it is as follows: Figure 2 As shown, vertical hoisting can be performed more stably;

[0029] After the blade support 200 is vertically hoisted onto the deck of the cargo ship, because the first and second tilting lugs 21 and 22 of the hoisting tilting auxiliary component 100 are pre-connected with ropes, the workers can pull the blade support 200 through the ropes, and the sling above will slowly release, eventually... Figure 4 The frame 1 is flipped and lies horizontally on the deck. The first flipping lug 21 and the two second flipping lugs 22 set on one side of the frame 1 can form a triangular point, which serves as the force point for flipping and pulling. This can make the lifting and flipping auxiliary component 100 bear force evenly and stably, and prevent the blade support 200 from tipping over.

[0030] Thus, the aforementioned hoisting and flipping auxiliary component 100 facilitates the vertical hoisting and flipping of the blade support 200.
