Description

Technical Field

[0001] The utility model relates to the field of wind turbine blade manufacturing and processing, in particular to a wind turbine blade main beam storage device. Background Art

[0002] As a clean and renewable energy source, wind power generation has developed rapidly in recent years. With the continuous increase in the power of wind turbines, the size of wind turbine blades has also increased, which has put forward higher requirements for the manufacturing, transportation and storage of wind turbine blades.

[0003] The main beam of a wind turbine blade is an important part of the wind turbine blade. It can be tens of meters long and weigh tens of tons. During the manufacturing process of wind turbine blades, the main beam needs to be hoisted, turned over, and spliced ​​many times. In order to facilitate the storage and use of the main beam, an efficient, safe, and space-saving main beam storage device is needed.

[0004] At present, the device for storing the main beam of wind turbine blades mainly adopts a transverse plate structure. For example, Chinese patent document CN113561149A (hereinafter referred to as "Document 1") discloses a storage device for facilitating the storage and retrieval of the main beam of wind turbine blades, comprising a support frame, on which a plurality of transverse plates for placing the main beams are arranged at intervals in the vertical direction, and each layer of the transverse plates is assembled on the support frame by rotating in the horizontal direction, so that when the main beam on each layer of the transverse plates except the uppermost transverse plate needs to be taken out, the adjacent upper transverse plates can be rotated in the horizontal direction to make room for the main beam to be taken out.

[0005] However, the technical solution disclosed in document 1 has the following technical problems:

[0006] Inconvenient operation: When you need to take the main beam on the non-top horizontal board, you need to rotate the upper horizontal board first to make room for operation. The operation steps are cumbersome and inefficient. Especially when storing multiple layers of main beams, taking the main beam on the lower layer requires rotating the upper horizontal board in turn, which is more time-consuming and labor-intensive.

[0007] Insufficient safety: During the rotation of the horizontal board, due to the large size and weight of the main beam, it is easy to tilt or slide, which poses a great safety hazard. In addition, the rotation of the horizontal board requires a large operating space, which also increases the safety risks of personnel and equipment. Utility Model Content

[0018] Figure 2 This is a schematic structural diagram of a telescopic support rod of a wind turbine blade main beam storage device according to one embodiment of the utility model when it is extended. DETAILED DESCRIPTION

[0019] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic structural diagram of a wind turbine blade main beam storage device according to an embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of the wind turbine blade main beam storage device according to one embodiment of the utility model when the telescopic support rod is extended. Figure 1 and Figure 2 As shown, this embodiment discloses a wind turbine blade main beam storage device, comprising a plurality of vertically arranged support frames 1. Each support frame 1 is provided with a multi-layer support structure for supporting the main beam at different heights (not shown in the figure).

[0021] In order to realize convenient access to the main beam, a set of pneumatic devices 2, 3 is provided on each layer of the supporting structure. Each set of pneumatic devices 2, 3 includes two cylinders 2, 3 respectively arranged on both sides of the telescopic support rod 4, and the two cylinders 2, 3 are linked to synchronously drive the extension or retraction of the telescopic support rod 4 to place the main beam on the telescopic support rod 4 or remove it from the telescopic support rod 4.

[0022] Both ends of each telescopic support rod 4 are connected to the piston rods of a set of pneumatic devices 2 and 3, respectively, and are located between two adjacent support frames 1. Each telescopic support rod 4 is used to support a main beam. This structural design enables each main beam to have an independent support and access mechanism, improves access efficiency, and avoids mutual interference.

[0023] In order to realize the telescopic function, the telescopic support rod 4 in this embodiment includes at least two rod bodies connected in sequence. A sliding connection structure is provided between the rod bodies, which allows the rod bodies to slide relative to each other, thereby realizing the telescopic support rod 4 to be telescopic, so as to facilitate the access of the main beam.

[0024] like Figure 2 As shown, the sliding connection structure includes a sliding sleeve disposed between two adjacent rod sections and slidably sleeved on the two adjacent rod sections. The provision of the sliding sleeve can reduce the friction force when the rods slide, making the telescopic movement more stable.

[0025] In order to limit the movement range of the sliding sleeve, the sliding connection structure also includes a limiting mechanism for limiting the sliding sleeve on two adjacent rods. The setting of the limiting mechanism can prevent the rod 41 from being separated during the extension process, thereby ensuring the safety of the device.

[0026] In this embodiment, the limiting mechanism includes a limiting pin provided on the sliding sleeve and a limiting hole provided on two adjacent rod sections and cooperating with the limiting pin. When the telescopic support rod 4 is extended or retracted, the limiting pin will slide in the limiting hole, thereby limiting the moving range of the sliding sleeve, ensuring that the telescopic support rod 4 is extended and retracted within a preset range. These contents are not shown in the figure, and those skilled in the art can adjust them according to specific needs.

[0027] In order to achieve precise control of the telescopic support rod 4, the pneumatic devices 2 and 3 in this embodiment also include an air circuit control system (not shown in the figure) connected to the cylinders 2 and 3. The air circuit control system is used to control the inflation and exhaust of the cylinders 2 and 3 to control the extension and retraction of the telescopic support rod 4, thereby realizing the automatic storage and retrieval of the main beam.

[0028] In order to further improve the stability and space utilization of the device, the storage device of this embodiment further includes a guide rail (not shown in the figure) arranged on the support frame 1. The telescopic support rod 4 is slidably connected to the guide rail, and the guide rail is used to guide the telescopic direction of the telescopic support rod 4. The provision of the guide rail can effectively prevent the telescopic support rod 4 from getting stuck or deflected during the telescopic process, thereby improving the operational stability and reliability of the device.

[0029] In specific implementation, the guide rail can be a V-shaped guide rail, and a slider (not shown in the figure) that matches the V-shaped guide rail is provided on the telescopic support rod 4. This structural design can effectively limit the lateral movement of the telescopic support rod 4, so that it can only be extended and retracted along the direction of the guide rail, thereby improving the stability of the device and space utilization.

[0030] In summary, the utility model provides a wind turbine blade main beam storage device with a simple structure, convenient operation, safety and reliability. By adopting a pneumatically driven telescopic support rod structure, the main beam can be directly placed at or removed from a designated position without rotating the cross plate as in the prior art, thereby solving the problems of inconvenient operation, insufficient safety and low space utilization in the prior art, and improving the storage and retrieval efficiency and safety of the wind turbine blade main beam.

[0031] This specific implementation method describes in detail a preferred implementation method of the utility model, and describes in detail each technical feature in conjunction with the accompanying drawings. It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solution described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents, so as to implement the technical solution of the utility model.
