[0032] See also Figure 1 , Figure 1 The schematic diagram of the structure of the pre-embedded blade root demoulding device 100 in one embodiment of the utility model is shown. One embodiment of the utility model provides a pre-embedded blade root demoulding device 100, which is used to demould the blade root of the blade. The end surface of the blade root is provided with a plurality of bolt holes. The pre-embedded blade root demoulding device 100 includes a connecting member 110, a fastener and a hoisting member 120. The connecting member 110 is provided with a plurality of first mounting holes corresponding to the bolt holes; the fastener passes through the first mounting holes and matches with the bolt holes so that the connecting part is connected to the end of the blade root; the hoisting member 120 is connected to the connecting member 110, and the hoisting member 120 is used to connect with the hoisting equipment to hoist the blade root so that the blade root is separated from the tooling.
[0033] The utility model provides a pre-embedded blade root demoulding device 100, which is used to demould the blade root of the blade. Since a plurality of bolt holes are arranged on the end face of the blade root, the present application cleverly utilizes the bolt holes, and by arranging a first mounting hole corresponding to the bolt hole on the connecting member 110, and then passing a fastener through the first mounting hole and threadedly cooperating with the threaded hole on the blade root, the connecting member 110 can be fixedly connected to the blade root. By fixing the hanging member 120 to the connecting member 110, and connecting the hanging member 120 to the hanging device through the hanging device, the hanging of the blade root can be realized, so that the blade root is separated from the tooling. The pre-embedded blade root demoulding device 100 with the above structure cleverly utilizes the structural characteristics of the blade root, and the blade root is demoulded by using the demoulding device, which can prevent the blade root from deformation while facilitating demoulding.
[0034] It should be noted that there is no limitation on the specific structure of the connecting member 110, and the connecting member 110 can be set to a frame form in any shape of a triangle, rectangle, square, trapezoid or polygon. The first mounting hole can be set to a through hole or a threaded hole, and can be set according to specific needs. In this embodiment, the fastener can be a bolt. There is no limitation on the specific structure of the hanging member 120, and it can be of any shape as long as it can be connected to the connecting member 110 and can be connected to the hanging equipment. It should be noted that the hanging member 120 does not contact the blade root, and the hanging member 120 can protrude from the blade root along the radial direction of the blade root, or it can be connected to the side of the connecting member 110 away from the blade root, and protrude in the direction away from the blade root along the axial direction of the blade root.
[0035] like Figure 1 As shown, in one embodiment, the connecting member 110 includes a flange 111, and a plurality of first mounting holes are arranged at intervals along the circumference of the flange 111. By arranging a plurality of first mounting holes at intervals in the circumferential direction of the flange 111, the area where the connecting member 110 is connected to the blade root is increased, so that the force applied to the blade root is more uniform, which is conducive to preventing deformation of the blade root during hoisting.
[0036] like Figure 2 As shown, in one embodiment, the connector 110 further includes a reinforcing rib 112, which is arranged along the radial direction of the flange 111, passes through the center of the flange 111, and both ends of the reinforcing rib 112 are fixedly connected to the flange 111. The reinforcing rib 112 is arranged on the flange 111 to strengthen the strength of the flange 111, so that the flange 111 is prevented from deforming after being stressed, and further, the blade root is prevented from being deformed during hoisting, which is beneficial to improving the demoulding effect of the blade root.
[0037] like Figure 2 As shown, in one embodiment, there are multiple reinforcing ribs 112, and the multiple reinforcing ribs 112 are evenly distributed along the surface where the flange 111 is located. By evenly arranging multiple reinforcing ribs 112 on the flange 111, on the one hand, the force on the flange 111 is made more uniform, and on the other hand, the strength of the flange 111 can be further enhanced, thereby preventing the deformation of the flange 111 during hoisting, and further preventing the deformation of the blade root during hoisting, so as to improve the reliability of demoulding.
[0038] In one embodiment, the two ends of the reinforcing rib 112 are welded and fixed to the flange 111. The two ends of the reinforcing rib 112 are welded and fixed to the flange 111, which has a simple process, reliable fixation and can save costs.
[0039] In one embodiment, at least one pair of first connection holes is provided on the flange 111, and the line connecting the pair of first connection holes passes through the center of the flange 111. Through holes are provided at both ends of the reinforcing rib 112, and bolts pass through the first connection holes and the through holes to fix the reinforcing rib 112 to the flange 111. In this embodiment, the first connection hole can be a threaded hole or a through hole. By providing the first connection holes on the flange 111, and the connection of the first connection holes that appear in pairs passes through the center of the flange 111, and by providing both ends of the reinforcing rib 112, bolts pass through the first connection holes and the second connection holes to fix the reinforcing rib 112 to the flange 111, so that the extension direction of the reinforcing rib 112 passes through the center of the flange 111.
[0040] It is understandable that when the first connection hole is a threaded hole, the bolt and the threaded hole can be threadedly matched to achieve fixed connection between the reinforcing rib 112 and the flange 111; if the first connection hole is a through hole, the bolt is locked by a nut when passing through the first connection hole and the through hole on the flange 111. In this way, installation is convenient, the process is simple, and the flange 111 is not easily deformed.
[0041] It should be noted that there is no limit on the number of the first connection holes, but the first connection holes appear in pairs and are evenly distributed along the circumferential direction of the flange 111 .
[0042] In one embodiment, the hanging member 120 is fixed by welding to the flange 111. By welding the hanging member 120 to the flange 111, the process is simple, the fixing is reliable, and the processing is convenient.
[0043] like Figure 1 and Figure 2As shown, in one embodiment, the hanging member 120 is constructed as an arc-shaped plate-like structure, a plurality of second connection holes are provided on the hanging member 120, and a plurality of second mounting holes are provided on the flange 111, and bolts are passed through the second connection holes and the second mounting holes to fix the hanging member 120 to the flange 111. By constructing the hanging member 120 as an arc-shaped plate-like structure, the structure of the hanging member 120 can adapt to the structure of the flange 111, so that the adaptation area of the hanging member 120 and the flange 111 is larger, thereby increasing the area of connection between the flange 111 and the hanging member 120, thereby improving the reliability of the connection between the two. By providing the second connection hole on the hanging member 120, providing the second mounting hole on the flange 111, and passing the bolts through the first connection hole and the second mounting hole, the hanging member 120 and the flange 111 are fixedly connected, and the structure is simple and easy to install. Among them, the first connection hole is a through hole, and the second mounting hole can be a through hole or a threaded hole. As a preferred solution, the second mounting hole is configured as a threaded hole. With this configuration, the hanging component 120 and the flange 111 can be fixedly connected by simply engaging the bolt with the thread of the second mounting hole.
[0044] like Figure 1 and Figure 2 As shown, in one embodiment, a hoisting hole 121 is provided on the hoisting member 120, and the hoisting hole 121 is used to connect with the hoisting equipment. By providing the hoisting hole 121 on the hoisting member 120, the connection between the hoisting member 120 and the hoisting equipment is realized, thereby realizing the hoisting of the blade root. It should be noted that there is no limitation on the number of hoisting holes 121, which can be one, two, three or even more. It can be set according to actual needs.
[0045] like Figure 1 and Figure 2 As shown, in one embodiment, there are multiple hoisting holes 121, and the multiple hoisting holes 121 are evenly distributed along the extension direction of the hoisting member 120. Two hoisting holes 121 are provided, and the multiple hoisting holes 121 are evenly distributed along the extension direction of the hoisting member 120, which can improve the balance of the blade root hoisting while ensuring the hoisting effect, thereby further preventing the blade root from being deformed.
[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
