Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade technology, specifically to a device for applying adhesive to the joint of wind turbine blades. Background Technology

[0002] Most wind turbine blades are made by bonding sheared webs and semi-skins together. The adhesive plays a crucial role in receiving and transmitting the loads from the various components. Therefore, adhesive is an indispensable structural material in wind turbine blades, and coating devices are typically used when applying adhesive to the webs.

[0003] The existing coating device fixes the web plate on the worktable and coats it with adhesive using a coating brush. However, during the process of flipping the web plate, the operator needs to open the clamp on the fixed table and flip it over, which causes the freshly coated side to easily stick to the clamp.

[0004] The coating device described above has a drawback: because it is difficult for operators to directly flip the coated web, the adhesive tends to stick to the operator's hands or the clamps, thus reducing the effectiveness of the device. Utility Model Content

[0005] This invention proposes a device for applying adhesive to the joint of wind turbine blades, which solves the problem in the prior art that it is difficult for operators to directly flip the coated web, resulting in the adhesive easily sticking to the operator's hands or clamps.

[0006] The technical solution of this utility model is as follows: A device for applying adhesive to the joint of wind turbine blades, including a support plate, and further comprising:

[0007] The connecting rod is mounted on the upper surface of the support plate. A movable tube is slidably connected to the outer surface of the connecting rod. A push rod motor is mounted on the front side of the support plate. The output end of the push rod motor is mounted on the lower surface of the movable tube. The connecting shaft is rotatably connected to the inside of the movable tube. A connecting plate is mounted on the outer surface of the connecting shaft. The connecting plate is mounted on the outer surface of the connecting shaft. A connecting frame is rotatably connected to the rear end of the connecting shaft. The movable block is slidably connected to the connecting frame. A fixing pin passes through the upper surface of the movable block. One end of the fixing pin, which passes through the movable block, is threaded through the connecting frame. A plug rod is mounted on the front side of the movable block. The front end of the plug rod passes through the connecting plate. The movable plate is slidably connected to the connecting frame. A fixing block is mounted on the lower surface of the movable plate. A connecting box is mounted on the lower surface of the fixing block. An auxiliary roller is rotatably connected inside the connecting box.

[0008] As a preferred embodiment of the adhesive coating device for the wind turbine blade connection described in this utility model, in order to better promote the movement of the adhesive, a push plate is slidably connected inside the connection box, and a moving rod is installed on the upper surface of the push plate.

[0009] In a preferred embodiment of the adhesive coating device for the connection of the wind turbine blade described in this utility model, in order to better move the push plate, the outer surface of the moving rod extends through the connection box, and a buffer spring is installed on the upper surface of the connection box.

[0010] In a preferred embodiment of the adhesive coating device for the connection of the wind turbine blade described in this utility model, in order to enable the moving rod to be reset by the buffer spring after it moves, the outer surface of the moving rod passes through the interior of the buffer spring, and a blocking plate is installed at the top of the moving rod and the buffer spring.

[0011] As a preferred embodiment of the adhesive coating device for the connection of wind turbine blades described in this utility model, in order to add adhesive to the connection box, the front of the connection box is hinged to an opening and closing door, and the front of the opening and closing door is fixed to the front of the connection box by bolts.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, by manipulating the connecting frame to rotate along the connecting shaft, and then manipulating the moving block to move forward along the connecting frame, the moving block moves forward and drives the insertion rod to move forward, thereby adjusting the angle of the auxiliary roller. Compared with the prior art of directly flipping the web plate as a whole, this device can coat the back side without flipping the web plate, reducing the number of times the operator's hands get sticky with adhesive.

[0015] In this invention, by manipulating the moving handle to move back and forth, the connecting box moves back and forth, so that the auxiliary roller coats along the surface of the web. Compared with the prior art of directly coating the web, this device can make the auxiliary roller move in the same direction, avoiding the situation where the operator's hands stick to the adhesive during the coating process.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, this embodiment proposes a wind turbine blade joint adhesive coating device, including a support plate 1, a connecting rod 2, a moving tube 3, a push rod motor 4, a connecting shaft 5, a connecting plate 6, a connecting frame 7, a moving block 8, a fixing pin 9, a plug rod 10, a moving plate 11, a fixing block 12, a connecting box 13, and an auxiliary roller 14.

[0025] like Figure 4 and Figure 5As shown, connecting rod 2 is mounted on the upper surface of support plate 1. A moving tube 3 is slidably connected to the outer surface of connecting rod 2. A push rod motor 4 is mounted on the front of support plate 1. The push rod motor 4 is controlled by an external single-control switch and requires an external power supply. The output end of the push rod motor 4 is mounted on the lower surface of the moving tube 3. Connecting shaft 5 is rotatably connected inside the moving tube 3. A connecting plate 6 is mounted on the outer surface of connecting shaft 5. Multiple sets of insertion holes are opened inside the connecting plate 6. The insertion rod 10... Figure 4 The connecting plate 6 is located inside the top insertion hole. The connecting plate 6 is mounted on the outer surface of the connecting shaft 5. A connecting frame 7 is rotatably connected to the rear end of the connecting shaft 5. A movable block 8 is slidably connected within the connecting frame 7. A fixing pin 9 passes through the upper surface of the movable block 8, with one end of the fixing pin 9 threaded through the connecting frame 7. A connecting rod 10 is mounted on the front of the movable block 8, with its front end passing through the connecting plate 6. A movable plate 11 is slidably connected within the connecting frame 7. A fixing block 12 is mounted on the lower surface of the movable plate 11. The lower surface of the fixing block 12... A connecting box 13 is installed, and an opening and closing door 19 is hinged to the front of the connecting box 13. The front of the opening and closing door 19 is fixed to the front of the connecting box 13 with bolts. In order for the operator to add adhesive inside the connecting box 13, a moving handle 20 is installed on the back of the connecting box 13. A support leg is installed on the lower surface of the support plate 1. An auxiliary roller 14 is rotatably connected inside the connecting box 13. An auxiliary groove is opened on the lower surface of the connecting box 13. The size of the auxiliary groove is adapted to the size of the auxiliary roller 14, so that a large amount of adhesive will not be carried out during the rotation of the auxiliary roller 14.

[0026] like Figure 5 As shown, a push plate 15 is slidably connected inside the connecting box 13. A moving rod 16 is installed on the upper surface of the push plate 15. The outer surface of the moving rod 16 passes through the connecting box 13. A buffer spring 17 is installed on the upper surface of the connecting box 13. When the adhesive has been used for a period of time, the blocking plate 18 moves downward to coat the upper surface of the web when the auxiliary roller 14 is coated. When the auxiliary roller 14 coats the lower surface of the web, the blocking plate 18 moves upward to drive the moving rod 16 to move downward. The downward movement of the moving rod 16 drives the push plate 15 to move downward along the connecting box 13. The downward movement of the blocking plate 18 compresses the buffer spring 17. The downward movement of the push plate 15 pushes the adhesive in the connecting box 13 downward to move closer to the auxiliary roller 14, thus accumulating the adhesive. The outer surface of the moving rod 16 passes through the interior of the buffer spring 17. The blocking plate 18 is installed at the top of the moving rod 16 and the buffer spring 17.

[0027] In this embodiment, as Figure 2 and Figure 3As shown, a connecting block 21 is slidably connected inside the support plate 1. A movable frame 22 is mounted on the upper surface of the connecting block 21. The movable frame 22 can move inward without moving along the center of the support plate 1. The connection point is moved to directly below the auxiliary roller 14 based on its position on the web, allowing the operator to coat the connection point using the auxiliary roller 14. The upper surface of the connecting block 21 is fixed inside the support plate 1 by bolts. An auxiliary plate 23 is slidably connected inside the movable frame 22. A mounting pin 24 passes through the outer side of the movable frame 22, with one end of the mounting pin 24 penetrating the movable frame 22 and pressing against the auxiliary plate 23. A connecting groove is formed on the upper surface of the support plate 1. A plate 23 is set in the connecting groove. The auxiliary plate 23 can move upward or inward along the inside of the connecting groove. A fixing plate 25 is installed on the inner side of the auxiliary plate 23. A moving plate 26 is slidably connected inside the auxiliary plate 23. A fixing tube 27 is installed on the upper surface of the auxiliary plate 23. An auxiliary rod 28 passes through the inside of the fixing tube 27. The outer surface of the auxiliary rod 28 passes through the inside of the auxiliary plate 23. The bottom end of the auxiliary rod 28 is installed on the upper surface of the moving plate 26. A plug pin 29 passes through the outer surface of the fixing tube 27. One end of the plug pin 29 that passes through the fixing tube 27 abuts against the auxiliary rod 28. An auxiliary spring 30 is installed on the upper surface of the moving plate 26. The top end of the auxiliary spring 30 is installed inside the auxiliary plate 23.

[0028] In this embodiment, the operating door 19 is flipped upward to open, adhesive is poured into the connecting box 13, the operating door 19 is flipped downward to close and fixed with bolts, the bolts on the connecting block 21 are loosened, the operating moving frame 22 is moved inward along the support plate 1 via the connecting block 21, the moving frame 22 moves inward to drive the auxiliary plate 23 to move inward, the auxiliary plate 23 moves inward to drive the fixing plate 25 to move inward, after the movement is complete, the bolts on the connecting block 21 are tightened to fix the connecting block 21, the operating auxiliary rod 28 is moved upward along the fixing tube 27, the operating auxiliary rod 28 moves upward to drive the moving plate 26 to move upward along the auxiliary plate 23, the moving plate 26 moves upward to compress the auxiliary spring 30, the operating web plate is placed on the fixing plate 25, the operating auxiliary rod 28 is released, the auxiliary spring 30 rebounds to drive the moving plate 26 to move downward, the moving plate 26 moves downward to drive the auxiliary rod 28 to move downward, the moving plate 26 moves downward to contact the web plate, the operating insertion pin 29 passes through the fixing tube 27 to press against the auxiliary rod 28;

[0029] Start the push rod motor 4. The output end of the push rod motor 4 moves upward, causing the moving tube 3 to move upward along the connecting rod 2. The moving tube 3 moves upward, causing the connecting shaft 5 to move upward. The connecting shaft 5 moves upward, causing the connecting frame 7 to move upward. The connecting frame 7 moves upward, causing the moving plate 11 to move upward. The moving plate 11 moves upward, causing the fixing block 12 to move upward. The fixing block 12 moves upward, causing the connecting box 13 to move upward. After the movement is complete, turn off the push rod motor.

[0030] Manipulate the moving handle 20 to move the connecting box 13 back and forth. The back and forth movement of the connecting box 13 causes the fixing block 12 to move back and forth. The back and forth movement of the fixing block 12 causes the moving plate 11 to move back and forth along the inside of the connecting frame 7. The back and forth movement of the connecting box 13 causes the auxiliary roller 14 to move back and forth. The auxiliary roller 14 rolls back and forth along the web, so that the auxiliary roller 14 dips into the adhesive in the connecting box 13 to coat the connection.

[0031] After the upper surface of the web is coated, the movable plate 11 is moved forward along the connecting frame 7 to disengage the auxiliary roller 14 from the connection point. The fixing pin 9 is loosened counterclockwise and pulled out. The movable block 8 is moved backward along the connecting frame 7. The backward movement of the movable block 8 drives the insertion rod 10 to move backward. The insertion rod 10 moves backward and is pulled out from the insertion hole at the top. The connecting frame 7 is rotated along the connecting shaft 5. After rotation, the movable block 8 is moved forward to drive the insertion rod 10 to move forward. The insertion rod 10 moves forward and is inserted into the corresponding insertion hole. The fixing pin 9 is inserted into the connecting frame 7 through the movable block 8. The fixing pin 9 is then rotated clockwise to fix the movable block 8. The above operation is repeated to coat the web connection point.

[0032] When the adhesive on the surface of the auxiliary roller 14 decreases, the manipulator 18 moves upward (at this time, the blocking plate 18 is flipped to the bottom), which drives the moving rod 16 to move upward. The moving rod 16 moves upward, which drives the push plate 15 to move upward. The blocking plate 18 moves upward, compressing the buffer spring 17. The push plate 15 moves upward, which gathers the adhesive in the connecting box 13 toward the auxiliary roller 14.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
