Description

Technical Field

[0001] The invention relates to the technical field of non-metal composite material processing and forming, and in particular to a wind turbine blade segmented web bonding and docking position control tool and a use method thereof. Background Art

[0002] With the development of larger blades, the length of blade webs is getting longer and longer, and the area of ​​web molds in the workshop is getting larger and larger. In order to reduce the use area of ​​the web workshop, the industry usually divides the webs into sections at about 60m, and the root tip webs are made separately. In this way, the root tip web molds can be arranged reasonably, greatly reducing the area occupied by the web mold workshop. At the same time, the height of the tip web is smaller, and a simple press-down tooling can be used instead of the overall press-down tooling to save tooling costs.

[0003] The current control scheme for segmented web bonding in the industry is:

[0004] 1) After making the apical section webs respectively, see Figure 1 , apply adhesive to the PS surface beam area of ​​the main shell half according to the process requirements, use the integral pressing tool to lift the root web, move it to the root position of the PS surface of the main shell half, and install the integral pressing tool on the base at the corresponding position of the main mold and then fix it and press it down, so that the root web is bonded to the beam area with adhesive to complete the bonding of the root web.

[0005] 2) See Figure 2 , use the lifting beam to lift the tip web and move it to the tip of the PS surface of the main shell half, manually adjust the root of the tip web to align with the tip of the root web, and gradually drop it until the tip web completely falls on the adhesive to complete the docking of the tip web and the root web. Figure 4 Finally, after removing the lifting beam, install the simple pressing tool for the tip web from the root to the tip to complete the tip web bonding. When the lifting beam lifts the tip web, there is an angle between the tip web and the root web. In order to ensure that the tip web can be bonded smoothly, this angle is offset upward from the tip side of the tip web. Figure 3 This angle will cause the tip web to fall down and after bonding is completed, there will be a butt gap H between its root side and the tip side of the root web, see Figure 5The process requirement for the butt gap H is ≤10mm. In actual production, the butt gap H is often 20-30mm, which exceeds the standard requirement. If it is adjusted, it is necessary to use a lifting beam to lift the tip web again and re-apply adhesive for bonding. Moreover, it cannot be completely guaranteed that the butt gap H is adjusted to a qualified level in one go, which greatly affects the molding time. The cost will also increase with the increase in adhesive usage. Therefore, some manufacturers make concessions on the problem of out-of-tolerance butt gap H and do not make adjustments. If the butt gap H is too large, it will affect the stiffness transmission of the web at the butt joint position, which may cause cracks in the butt joint position of the segmented web during subsequent blade operation. In severe cases, it may cause blade damage and breakage, which has a greater impact.

[0006] Therefore, the existing technology suffers from insufficient control accuracy in the bonding position of the segmented webs of wind turbine blades, angle and position deviations during the bonding process of the tip webs, resulting in problems such as out-of-tolerance joints and increased use of adhesive, which greatly affects the molding time, increases production costs, and even causes cracks in the bonding position of the segmented webs during blade operation.

[0061] The overall structure of the first clamping tool 3 is simple and efficient, with high precision, which can effectively improve the bonding efficiency and quality and reduce labor costs and operating difficulties.

[0062] Specifically, the first bracket 4 includes a first branch pipe 401 , a second branch pipe 402 and a first transverse pipe 403 . The first branch pipe 401 and the second branch pipe 402 are arranged in parallel.

[0080] The guide groove 6 is connected to the first branch pipe 401 through the first connecting rod 7, which helps to transfer the load to the first branch pipe 401 and provide support for the guide groove 6 to prevent the guide groove 6 from deflecting when impacted by the load, and unable to maintain a suitable position and angle, affecting the formation of a guide structure with the second clamping tool 11.

The impact force generated by the internal components of the guide structure during the bonding process can be evenly decomposed onto the first clamping fixture 3 and the second clamping fixture 11, avoiding a single component from being subjected to a large torque and extending the service life of the component.
