Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade transportation, specifically relating to a connector for a wind turbine blade root end stacking support. Background Technology

[0002] With the development of the wind power industry, offshore wind turbines are becoming increasingly larger, with wind turbine blades becoming larger and longer. This poses a significant challenge to the maritime transport of these blades. Currently, transport supports are commonly used to secure wind turbine blades to the deck of cargo ships. These transport supports consist of root supports and tip supports. The root supports are used to support and secure the root portion of the wind turbine blade, while the tip supports are typically located at the tip third of the blade to support and secure the other end.

[0003] Since wind turbine blades occupy a large deck space, in some cases it is necessary to stack two wind turbine blades to save space. In addition to manufacturing new blade root end supports, this utility model provides another solution, which can increase the height and add layers to the original blade root end supports to save manufacturing costs. Utility Model Content

[0004] In response to the above, this utility model provides a connector for a wind turbine blade root end stacking support, which can achieve stable and reliable docking and connection between the upper and lower root end supports to form a double-layer wind turbine blade root end stacking support.

[0005] The publicly disclosed connector of the wind turbine blade root end stacking support includes a main frame, a first connecting plate, a second connecting plate, a first extension square tube, a docking block, and a docking sleeve.

[0006] A first connecting plate is fixed at each of the four corners of one side of the main frame. The first connecting plate is perpendicular to the main frame and has pin holes. The first connecting plate is used to connect with the connecting plate of the upper root end support through a pin shaft.

[0007] A second connecting plate is fixed at each of the four corners on the other side of the main frame. The second connecting plate is perpendicular to the main frame and also has pin holes. The second connecting plate is used to connect with the connecting plate of the lower root end support through a pin shaft.

[0008] Two first extended square tubes are fixedly connected to one side of the main frame. The two first extended square tubes are arranged opposite each other and are located on the same horizontal plane as the main frame. A docking block is fixedly connected to one side of the first extended square tube. The docking block is used to dock with the hollow tube of the upper root end support. A docking sleeve is fixedly connected to the other side of the first extended square tube. The docking sleeve is used to dock with the docking column of the lower root end support. The above-mentioned connecting parts are first docked and positioned with the lower root end support and the upper root end support respectively through the docking sleeve and the docking block, and then connected to them through the first connecting plate and the second connecting plate, which makes the connection more precise and convenient.

[0009] Furthermore, the connecting components of the aforementioned wind turbine blade root stacking support also include a reinforcing support column, a second extension square tube, and a limiting support column;

[0010] Two reinforcing support columns are fixedly connected to the side of the main frame away from the first extended square tube. The two reinforcing support columns are arranged opposite to each other and perpendicular to the main frame.

[0011] The main frame is fixedly connected to two sides of a second extended square tube. The second extended square tube is located on the same horizontal plane as the main frame. A limiting support column is fixedly connected to one side of the second extended square tube. The limiting support column is perpendicular to the second extended square tube. A docking block is also fixedly connected to the other side of the limiting support column and the second extended square tube. The docking block is also used to dock with the hollow tube of the upper root end support, so as to make the docking positioning more accurate. After the above-mentioned reinforcing support column and limiting support column come into contact with the plane of the lower root end support, they can play a supporting and reinforcing role, preventing twisting and collapse due to load.

[0012] Preferably, the limiting support column is composed of two right-angled backing plates connected in one piece, and multiple reinforcing ribs are fixedly connected between the two backing plates. Such a limiting support column can cooperate with the cross positioning component of the lower root end support. The two backing plates of the limiting support column are closely positioned with the positioning surfaces of the cross positioning component, which can further enhance the docking and positioning effect with the lower root end support.

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

[0014] The connecting component of the wind turbine blade root end stacking support described in this application, through the cooperative design of structural components such as the main frame, the first connecting plate, the second connecting plate, the first extended square tube, the docking block, and the docking sleeve, enables the upper and lower root end supports to be stably and reliably docked and connected through the connecting component of this application to form a double-layer wind turbine blade root end stacking support. It can increase the height and add layers on the basis of the original blade root end support to save manufacturing costs.

[0015] Further design improvements include strengthening the coordination between the support column and the limiting support column, which can provide support and reinforcement, preventing the connector from twisting and collapsing under load. Attached Figure Description

[0023] A first connecting plate 2 is fixed at each of the four corners of one side of the main frame 1. The first connecting plate 2 is perpendicular to the main frame 1. The first connecting plate 2 has pin holes and is used to connect with the connecting plate of the upper root end bracket 20 through a pin shaft.

[0024] The main frame 1 has four corners fixed with second connecting plates 3 respectively. The second connecting plates 3 are perpendicular to the main frame 1. The second connecting plates 3 also have pin holes. The second connecting plates 3 are used to connect with the connecting plates of the lower root end bracket 30 through pins.

[0025] Two first extension square tubes 4 are fixedly connected to one side of the main frame 1. The two first extension square tubes 4 are arranged opposite each other and are located on the same horizontal plane as the main frame 1. A docking block 5 is fixedly connected to one side of the first extension square tube 4. The docking block 5 is used to dock with the hollow tube 21 of the upper root end support 20. A docking sleeve 6 is fixedly connected to the other side of the first extension square tube 4. The docking sleeve 6 is used to dock with the docking column 32 of the lower root end support 30.

[0026] The connecting components of the aforementioned wind turbine blade root stacking support also include a reinforcing support column 7, a second extension square tube 8, and a limiting support column 9;

[0027] Two reinforcing support columns 7 are fixedly connected to the side of the main frame 1 away from the first extended square tube 4. The two reinforcing support columns 7 are arranged opposite to each other and perpendicular to the main frame 1.
