Description

Technical Field

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

[0002] As a clean and renewable energy source, wind power generation has developed rapidly around the world in recent years. In order to improve the efficiency of wind energy utilization, wind turbines are constantly developing in the direction of large-scale, and the size of wind turbine blades is constantly increasing. As the core component of wind turbines to capture wind energy, the design, manufacturing and quality control of wind turbine blades are crucial to the performance and life of wind turbines.

[0003] Wind turbine blades are mainly composed of main beams, webs, shells and other components. The main beam is the load-bearing skeleton of the blade and plays a vital role in the strength, rigidity and stability of the blade. The main beam is usually made by prefabrication, and its manufacturing process involves multiple links such as material cutting, laying, molding, and curing. Problems in any link may lead to defects in the main beam, such as internal cracks, bubbles, and delamination, which will seriously affect the quality and service life of the blade.

[0004] In order to ensure the quality and reliability of wind turbine blades and avoid defective main beams being used to assemble blades, it is usually necessary to perform non-destructive testing on the main beams before use. Non-destructive testing refers to a technical means of detecting internal defects of materials without destroying the material structure and performance. Common non-destructive testing methods for main beams include ultrasonic testing (UT), radiographic testing (RT), infrared thermal imaging testing (IRT), etc. Different testing methods have different principles and scopes of application. For example, UT testing is suitable for detecting defects such as cracks and bubbles inside the main beam, while RT testing is more suitable for detecting density changes and foreign matter inclusions inside the main beam.

[0005] When performing UT testing on the main beam, it is usually necessary to adjust the main beam to a vertical state to facilitate the movement of the ultrasonic probe and the acquisition of signals. However, the current device for storing the main beam of wind turbine blades mainly adopts a horizontal 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, including a support frame, on which are arranged multiple layers of horizontal plates for placing the main beams, the multiple layers of horizontal plates are arranged at intervals in the vertical direction, and each layer of the horizontal plates is rotated and assembled on the support frame in the horizontal direction, so that when the main beam on each layer of horizontal plates except the uppermost horizontal plate needs to be taken out, the adjacent upper horizontal plates can be rotated in the horizontal direction to make room for the main beam to be taken out.

[0006] Although this type of storage device with a horizontal plate structure is convenient for storing and accessing the main beam, it cannot flip the main beam from a horizontal storage state to a vertical state, resulting in the inability to perform UT testing on the main beam in the storage state, which requires a vertical state. In order to complete the test, the main beam needs to be taken out of the storage device first, and then flipped to a vertical state using a lifting device before the test can be performed. This operation process is cumbersome and complicated, not only inefficient, but also increases operating costs and safety risks.

[0007] Therefore, there is an urgent need for a flipping tool that can flip the main beam from a horizontal storage state to a vertical state, so as to facilitate UT testing of the main beam and other testing that requires a vertical state, thereby improving testing efficiency, reducing operating costs, and ensuring operational safety. Utility Model Content

[0008] In order to overcome the defects in the prior art, the utility model provides a rotatable main beam storage tooling, which can improve the detection efficiency and reduce the operation cost.

[0009] The utility model solves the above technical problems through the following technical solutions:

[0010] A rotatable main beam storage tooling includes a tooling bracket, on which a circular arc groove is provided; a first holding mechanism, which is arranged on the tooling bracket and is used to support one side of the main beam; a movable pressure plate, which is arranged on the tooling bracket and is used to press the other side of the main beam; and a sliding drive block fixedly connected to the first holding mechanism and the movable pressure plate, wherein the sliding drive block is slidably arranged in the circular arc groove, and the sliding drive block is arranged in the circular arc groove and driven by the driving mechanism to slide in the circular arc groove, so that the sliding drive block drives the first holding mechanism and the movable pressure plate to move relative to each other along the circular arc groove, thereby driving the main beam clamped by the first holding mechanism and the movable pressure plate to flip. The utility model realizes the rotation of the main beam through the coordinated action of the driving mechanism, the sliding drive block, the first holding mechanism and the movable pressure plate, and solves the problem in the prior art that the main beam storage device cannot flip the main beam, resulting in difficulty in detecting certain specific angles of the main beam.

[0011] Preferably, the driving mechanism includes a friction wheel disposed on the tooling bracket and located in the arc groove, and the sliding driving block is adapted to the friction wheel. The friction wheel is used to drive the sliding driving block, which has a simple and compact structure, a short transmission chain, and low energy loss, thereby improving the transmission efficiency.

[0012] Preferably, the friction wheel is in driving connection with the driving motor. By driving the friction wheel with the driving motor, the turning speed and angle of the main beam can be accurately controlled, thus avoiding the errors and safety risks that may be caused by manual operation, and the turning process is stable and controllable, and the positioning is accurate.

[0013] Preferably, the movable pressure plate includes a pressure plate and a hydraulic rod connected to the pressure plate, and the hydraulic rod is used to drive the pressure plate to rotate to control the pressure plate to clamp or release the main beam. The hydraulic rod is used to control the opening and closing of the movable pressure plate, which can conveniently and quickly clamp and release the main beam, and the hydraulic system can provide a large clamping force to ensure that the main beam will not loosen or slip during the flipping process, which is easy to operate and reliable to clamp.

[0014] Preferably, the arc groove and the sliding drive block are both set to be arc-shaped, and the curvature of the arc groove matches the curvature of the sliding drive block. The shape matching of the arc groove and the sliding drive block ensures that the sliding drive block slides smoothly in the arc groove, avoiding jamming or deviation, thereby improving the stability of the main beam flipping process. At the same time, this design also enhances the structural strength of the tooling, improves operational safety, and improves the stability and safety of the main beam flipping.

[0015] Preferably, the sliding drive block is provided with a driving connection part connected to the driving mechanism, one end of the sliding drive block is fixedly connected to the first holding mechanism, and the sliding drive block is hinged to the movable pressure plate at a position close to the one end. This design makes the sliding drive block drive the movable pressure plate with a smaller torque, and the main beam flipping process is smoother. At the same time, the clamping force of the movable pressure plate on the main beam is more uniform, avoiding local stress concentration, and the flipping is smooth and the force is uniform. Compared with the method of setting connections at both ends of the sliding drive block, this design makes the sliding drive block more compact, saves the space occupied by the tooling, and has a compact structure and saves space.

[0016] To sum up, the utility model solves the problem that the existing main beam storage device cannot flip the main beam by setting a rotatable structure, so that the main beam can be easily subjected to UT testing and other testing that requires a vertical state when stored, thereby improving the testing efficiency, reducing the operating cost, and ensuring the safety of operation.

[0020] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] Figure 1 This is a schematic structural diagram of a rotatable main beam storage tooling according to an embodiment of the utility model. Figure 2 This is a schematic structural diagram of a wind-rotatable main beam storage tooling after the sliding drive block is rotated 90° in one embodiment of the utility model. Figure 3 This is a schematic diagram of the structure of the wind rotatable main beam storage tooling when the movable pressure plate is opened in one embodiment of the utility model. Figures 1 to 3 As shown, the utility model provides a rotatable main beam storage tooling, including a tooling bracket 1, on which a circular arc groove is arranged; a first holding mechanism 5, which is arranged on the tooling bracket 1 and is used to support one side of the main beam; a movable pressure plate 2, which is arranged on the tooling bracket 1 and is used to press the other side of the main beam; and a sliding drive block 4 fixedly connected to the first holding mechanism 5 and the movable pressure plate 2, the sliding drive block 4 being slidably arranged in the circular arc groove, and the sliding drive block 4 is arranged in the circular arc groove and driven by a driving mechanism to slide in the circular arc groove, so that the sliding drive block 4 drives the first holding mechanism 5 and the movable pressure plate 2 to move relative to each other along the circular arc groove, thereby driving the main beam clamped by the first holding mechanism 5 and the movable pressure plate 2 to flip.

[0022] Specifically, the tooling bracket 1 can be set to a "U"-shaped structure, and the arc grooves are set on both sides of the top of the tooling bracket 1, and the shape of the arc groove is an arc with a radius of 10 meters. The curvature and shape of the arc groove can be adjusted according to actual needs. For example, the curvature and shape of the arc groove can be designed according to factors such as the length and weight of the main beam and the angle at which it needs to be flipped.

[0023] The first holding mechanism 5 is arranged on one side of the tooling support 1 to support one side of the main beam. The first holding mechanism 5 can be a support block fixedly arranged on the tooling support 1, or a support frame with adjustable height and angle to adapt to main beams of different sizes.

[0024] The movable pressure plate 2 is arranged on the other side of the tooling support 1 to press the other side of the main beam. Figure 3 As shown, the movable platen 2 includes a platen and a hydraulic rod 6 connected to the platen, the hydraulic rod 6 is used to drive the platen to rotate to control the platen to clamp or release the main beam. By controlling the extension and retraction of the hydraulic rod 6, the movable platen 2 can be opened and closed, thereby facilitating the loading and unloading of the main beam.

[0025] The sliding drive block 4 is located between the first holding mechanism 5 and the movable pressure plate 2, one end of which is fixedly connected to the first holding mechanism 5 and is hinged to the movable pressure plate 2 at a position close to the one end. The sliding drive block 4 is slidably arranged in the circular arc groove, and the shape of the sliding drive block 4 matches the curvature of the circular arc groove, both of which are arcs with a radius of 10 meters. This design ensures that the sliding drive block 4 slides smoothly in the circular arc groove, avoids jamming or deviation, and thus improves the stability of the main beam flipping process.

[0026] The sliding drive block 4 is also provided with a driving connection part connected to the driving mechanism, and the driving mechanism includes a friction wheel 3 arranged on the tooling bracket 1 and located in the arc groove, and the sliding drive block 4 is adapted to the friction wheel 3. The friction wheel 3 is drivingly connected to the driving motor (not shown in the figure).

[0027] The working principle of the utility model is as follows:

[0028] First, the hydraulic rod 6 is extended to rotate the movable platen 2 to the open state. Figure 3 Then, the main beam to be inspected is placed on the fixture bracket 1 , so that one side of the main beam is against the first holding mechanism 5 , and the other side is located below the movable pressure plate 2 .

[0029] Next, the hydraulic rod 6 is controlled to retract, so that the movable pressure plate 2 is rotated to a clamping state, and the main beam is firmly fixed on the tooling bracket 1.

[0030] Then, the driving motor is started, and the driving motor drives the friction wheel 3 to rotate, and the friction wheel 3 drives the sliding driving block 4 to slide along the circular arc groove. Since one end of the sliding driving block 4 is fixedly connected to the first holding mechanism 5, and is hinged to the movable pressure plate 2 at a position close to the one end, the sliding of the sliding driving block 4 will drive the first holding mechanism 5 and the movable pressure plate 2 to move relative to each other along the circular arc groove, thereby driving the main beam clamped between the first holding mechanism 5 and the movable pressure plate 2 to flip.

[0031] By controlling the rotation direction and angle of the drive motor, the flipping angle of the main beam can be accurately controlled. For example, the main beam can be flipped from a horizontal state to a vertical state to facilitate UT testing and other tests that require a vertical state.

[0032] The utility model solves the problem that the existing main beam storage device cannot flip the main beam by providing a rotatable structure, so that the main beam can be conveniently subjected to UT testing and other testing that requires a vertical state when stored, thereby improving testing efficiency, reducing operating costs, and ensuring operational safety.

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.
