Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing wind turbine blades, in particular to a glass fiber cloth laying and compacting hanger for wind turbine blades which can avoid ply interference. Background Art
[0002] Wind turbine blades are key components of wind turbine equipment. Their structure usually includes inner skin, outer skin, beam, etc. The beam is the main skeleton structure. The quality of the beam directly affects the overall quality of the wind turbine blade. The beam plays a major role in bearing the load during the operation of the blade. To ensure the structural strength of the beam, multiple layers of fiberglass cloth need to be repeatedly laid on the beam during its production process. During the manufacturing process of the wind turbine blade beam, dozens of layers of fiberglass cloth need to be laid in the mold. Usually, the glass fiber is laid manually by operators or with the help of laying equipment. The specific laying operation steps are: 1. Clean the inner surface of the mold and lay the demoulding cloth on the inner surface of the mold; 2. Lay the outer skin fiberglass cloth; 3. Apply glue, use special epoxy resin glue to evenly apply it on the surface of the laid outer skin fiberglass cloth; 4. Lay the prepared laying fiberglass cloth on the surface of the outer skin fiberglass cloth coated with glue; 5. Use special laying and compacting tools to compact the laid layer; 6. Complete the laying and compaction of multiple layers of fiberglass cloth in sequence.
[0003] Among them, the laying and compaction of the glass fiber cloth layer is the key to the entire laying process. During the laying and compaction process inside the cavity of wind turbine blades, especially blades with large pitch circles of 100 meters, the workers cannot stand stably in the cavity, resulting in a time-consuming and labor-intensive laying and compaction process. The current problems are: 1. When laying, workers standing inside the cavity for compaction will cause interference, and it is easy to collapse the laid cloth layer, resulting in wrinkles and rework; 2. When laying large blades, workers' arms cannot reach the edge of the cloth layer, making it difficult to lay the cloth layer on the side wall of the cavity. Utility Model Content

[0025] See also Figure 1 and Figure 2 As shown in the figure, the embodiment of the utility model proposes a fiberglass cloth laying and compacting hanger for wind turbine blades, which includes a mobile base 1 arranged on the side of the wind turbine blade mold platform and can move along its length direction, a gantry 2 is arranged on the mobile base 1, and a horizontal displacement driving device 3 across the wind turbine blade mold platform is arranged on the gantry 2, and a driving end of the horizontal displacement driving device 3 is connected to a suspension 4 located above the wind turbine blade mold platform, and a paving operation hanging basket 5 is fixed at the end of the suspension 4.

At this time, the guide rod electric cylinder 443 can provide a stable triangular support point for the horizontal cantilever 42 tilted to the right, thereby enhancing the stability of the ply laying operation basket 5 in the tilted state. Similarly, when the ply laying operation basket 5 needs to be tilted toward the left at an angle, the guide rod electric cylinder 443 and the rotating electric cylinder 441 act synchronously, and the rotating electric cylinder 441 outputs a corresponding angular displacement counterclockwise to adjust the horizontal cantilever 42 to the horizontal plane. At the same time, the guide rod of the guide rod electric cylinder 443 retracts a corresponding length and is locked, thereby providing a stable triangular support point for the horizontal cantilever 42 tilted to the left.

As a preferred embodiment of the present invention, the angle limit threshold of the angle sensor is 15°, and the angle sensor is connected to the industrial computer. When the tilt angle of the laying operation hanging basket 5 reaches 15°, the industrial computer sends a warning signal to the alarm, and sends an alarm to the construction worker through the alarm. At the same time, the industrial computer locks the angular displacement output of the rotary electric cylinder 441 until the current construction operation is completed and the construction worker manually releases it.
