Description

Technical Field

[0001] This application relates to the field of wind turbine tower body grinding technology, specifically to a circumferential seam grinding device for assembling segmented wind turbine tower bodies. Background Technology

[0002] Wind turbine towers are crucial support structures for wind turbine generators. Their main function is to support the wind turbine and nacelle, bear the load generated by the wind turbine, and transfer it to the foundation. They typically consist of a tower body, flanges, and a foundation. Segmented wind turbine tower bodies are a common tower structure, which involves manufacturing the tower body in multiple segments and then assembling these segments. The assembly method is usually welding, which results in circumferential welds. To ensure the aesthetic appearance of the product, these circumferential welds need to be ground. However, existing grinding equipment has a relatively small contact area between the grinding components and the circumferential welds, resulting in a long grinding time and low efficiency. Therefore, this paper proposes a circumferential weld grinding device for the assembly of segmented wind turbine tower bodies. Summary of the Invention

[0003] The purpose of this application is to address the technical problems of relatively small contact area between the grinding component and the circumferential weld, long grinding time required to complete the grinding of the entire circumferential weld, and low grinding efficiency. This application provides a circumferential weld grinding device for the assembly of segmented wind turbine tower bodies.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0008] The lifting mechanism is installed on one of the two columns of the frame, and the two columns are driven to rise and fall synchronously through the lifting mechanism.

[0009] The drive unit is located on the frame, the mounting bracket, and the shafts, and drives the three shafts to rotate synchronously.

[0010] Furthermore, the driving component includes a driving plate slidably mounted on the movable frame, the adjusting frame is provided with protrusions, and the driving plate has waist holes that are the same number as the protrusions and correspond one-to-one. The protrusions slide in cooperation with the waist holes, and the three waist holes are distributed obliquely from the middle to both sides.

[0011] Furthermore, a drive screw threaded through the drive plate is rotatably mounted on the movable frame, and a drive motor is mounted on the movable frame. The output shaft of the drive motor is connected to the drive screw via a pulley assembly.

[0012] Furthermore, the lifting component includes a lifting plate that is slidably mounted on the frame, the lifting plate having a strip groove, the column rod slidingly engaging with the strip groove, and the column rod having two spaced-apart limiting rings that both abut and overlap with the lifting plate.

[0018] Furthermore, the shaft is provided with ring plates that are spaced apart from the mounting bracket, and the grinding wheel abuts and overlaps with the ring plates.

[0019] The beneficial effects of this application are as follows:

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown, one embodiment of this application discloses a circumferential seam grinding device for assembling segmented wind turbine tower bodies, comprising:

[0030] The structure comprises a top frame 1, a transverse frame 2 slidably mounted on the top frame 1, and a movable frame 3 slidably mounted on the transverse frame 2. The top frame 1 is horizontal and fixedly mounted in a designated position. The transverse frame 2 is horizontal and slides along the horizontal direction. The movable frame 3 slides along the vertical direction. Three adjusting frames 4 are slidably mounted on the movable frame 3. The adjusting frames 4 slide along the horizontal direction. A connecting frame is mounted on the adjusting frame 4. The connecting frame is fixed on the adjusting frame 4. The connecting frame in the middle is frame body 1 5. The other connecting frames are frame body 2 6. A column rod 7 is slidably mounted on frame body 2 6. The column rod 7 is vertical and slides along the vertical direction. Mounting frames 8 are mounted on both column rod 7 and frame body 1 5. A shaft rod 9 is rotatably mounted on the mounting frame 8. The shaft rod 9 is horizontal. A grinding wheel 10 is mounted on the shaft rod 9. The grinding wheel 10 is vertical.

[0031] The driving component is set on the movable frame 3 and the adjusting frame 4, and drives the adjusting frame 4 located on both sides to slide synchronously.

[0032] The lifting mechanism is installed on the frame 5 and the two columns 7, and the two columns 7 are driven to rise and fall synchronously through the lifting mechanism.

[0033] The drive unit is installed on the frame 5, the mounting bracket 8 and the shaft 9, and drives the three shafts 9 to rotate synchronously.

[0034] In the initial state, the three adjusting frames 4 are close to each other, and the three grinding wheels 10 are on the same horizontal plane. When grinding the annular weld, the cylinder is placed horizontally on two spaced rotating trolleys, and the transverse frame 2 and the moving frame 3 are driven to slide until the grinding wheel 10 in the middle contacts and overlaps with the annular weld on the cylinder. The axis of the grinding wheel 10 and the axis of the cylinder are on the same vertical plane. Then, the adjusting frames 4 on both sides are driven to slide synchronously away from each other by the driving component, while the position of the adjusting frame 4 in the middle remains unchanged. Then, the two columns 7 are driven to slide synchronously downward by the lifting component, and the mounting frames 8 on both sides move downward synchronously until the grinding wheels 10 on both sides contact and overlap with the annular weld on the cylinder. At this time, the three grinding wheels 10 are arranged in an arc shape. The cloth and the ring weld seam on the cylinder are all in contact and overlap. Finally, the cylinder is driven to rotate by two rotating trolleys. At the same time, the three shafts 9 are driven to rotate synchronously by the drive unit, that is, the three grinding wheels 10 rotate synchronously and grind the ring weld seam together, increasing the contact area, improving grinding efficiency, and reducing the time required to grind the entire ring weld seam. When the grinding is completed, the three grinding wheels 10 stop rotating. The two column rods 7 are driven to slide upward synchronously by the lifting component until the three grinding wheels 10 are on the same horizontal plane. Then, the adjusting frame 4 on both sides is driven to slide synchronously to get closer to each other by the drive component. The transverse frame 2 and the moving frame 3 are driven to slide until the grinding wheel 10 in the middle is away from the cylinder. Finally, the ground cylinder is removed from the two rotating trolleys.

[0035] In summary, when in use, this application uses three arc-shaped and synchronously rotating grinding wheels 10 to grind the annular weld seam on the cylinder, increasing the contact area, improving grinding efficiency, reducing the time required to grind the entire annular weld seam, and being applicable to annular weld seams of different diameters, thus improving the flexibility and adaptability of use and making it more practical.

[0036] like Figure 2 As shown, in some embodiments, the driving component includes a driving plate 11 slidably disposed on the movable frame 3. The driving plate 11 is vertical and slides in the vertical direction. The adjusting frame 4 is provided with protrusions 12. The protrusions 12 are horizontal and fixed on the adjusting frame 4. The driving plate 11 has waist holes 13 that are the same number as the protrusions 12 and correspond one-to-one. The protrusions 12 and waist holes 13 are slidably engaged. The three waist holes 13 are inclined from the middle to both sides. The waist hole 13 in the middle is vertical, and the waist holes 13 on both sides are inclined and symmetrically distributed.

[0037] Referring to the above, in the initial state, the drive plate 11 is in the initial position, and the protrusion 12 is located at the bottom of the waist hole 13. In use, the drive plate 11 is driven to slide down to the limit position, and the three protrusions 12 slide into the three waist holes 13 respectively. The position of the adjustment bracket 4 in the middle position remains unchanged, and the adjustment brackets 4 on both sides slide synchronously to move away from each other, with the protrusion 12 approaching the top of the waist hole 13. Conversely, the drive plate 11 is driven to slide up to the initial position, and the three protrusions 12 slide into the three waist holes 13 respectively. The position of the adjustment bracket 4 in the middle position remains unchanged, and the adjustment brackets 4 on both sides slide synchronously to move closer to each other, with the protrusion 12 located at the bottom of the waist hole 13.

[0038] like Figure 2 As shown, in some embodiments, a drive screw 14 threaded through the drive plate 11 is rotatably provided on the movable frame 3. The drive screw 14 is in a vertical direction. A drive motor 15 is provided on the movable frame 3. The drive motor 15 is fixed on the movable frame 3. The output shaft of the drive motor 15 is connected to the drive screw 14 through a pulley assembly 16. The pulley assembly 16 includes two pulleys and a connecting belt. The two pulleys are respectively fixed on the output shafts of the drive screw 14 and the drive motor 15. The connecting belt is wound around the two pulleys.

[0039] Referring to the above, when in use, turn on the drive motor 15, the drive motor 15 works, the output shaft rotates forward, and drives the drive screw 14 to rotate together through the pulley assembly 16. The drive plate 11 will slide downward due to the thread action. Conversely, when the output shaft of the drive motor 15 rotates in reverse, it drives the drive screw 14 to rotate together through the pulley assembly 16, and the drive plate 11 will slide upward due to the thread action.

[0040] like Figure 5 As shown, in some embodiments, the lifting component includes a lifting plate 17 slidably disposed on the frame 5. The lifting plate 17 is horizontal and slides in the vertical direction. A strip groove 18 is provided on the lifting plate 17. The strip groove 18 is horizontal. The column rod 7 is slidably engaged with the strip groove 18. Two limiting rings 19 are provided on the column rod 7, which are spaced apart and both abut against and overlap the lifting plate 17. Both limiting rings 19 are horizontal and fixed on the column rod 7.

[0041] Referring to the above, in the initial state, the lifting plate 17 is in the initial position, and the two columns 7 are close to the middle position of the lifting plate 17. When the adjusting frames 4 on both sides slide synchronously to move away from each other, the two columns 7 slide synchronously in opposite directions in the horizontal direction within the strip groove 18 to move away from the middle position of the lifting plate 17, driving the lifting plate 17 to slide downward. The two limiting rings 19 together limit the columns 7, so that the columns 7 slide downward together with the lifting plate 17, thereby driving the two columns 7 to slide downward synchronously. Conversely, the lifting plate 17 is driven to slide upward to the initial position, and the two limiting rings 19 together limit the columns 7, so that the columns 7 slide upward together with the lifting plate 17, thereby driving the two columns 7 to slide upward synchronously. When the adjusting frames 4 on both sides slide synchronously to move closer to each other, the two columns 7 slide synchronously in opposite directions in the horizontal direction within the strip groove 18 to move away from the middle position of the lifting plate 17.

[0042] like Figure 5 As shown, in some embodiments, a lifting screw 20 with a thread passing through the lifting plate 17 is rotatably provided on the frame 5. The lifting screw 20 is in a vertical direction. A lifting motor 21 with an output shaft connected to the lifting screw 20 is provided on the frame 5. The lifting motor 21 is fixed on the frame 5.

[0043] Referring to the above, when in use, turn on the lifting motor 21. When the lifting motor 21 is working, the output shaft rotates forward, driving the lifting screw 20 to rotate together. The lifting plate 17 will slide downward due to the thread action. Conversely, when the output shaft of the lifting motor 21 rotates in reverse, it drives the lifting screw 20 to rotate together, and the lifting plate 17 will slide upward due to the thread action.

[0044] like Figures 3-4As shown, in some embodiments, the drive unit includes a fixed rod 22 rotatably mounted on the frame 5. The fixed rod 22 is horizontal, and two symmetrically distributed crossbars 23 are slidably mounted on the fixed rod 22. The crossbars 23 are horizontal and slide in the horizontal direction. The fixed rod 22 has a receiving groove, and the two crossbars 23 are slidably engaged with the receiving groove. When the fixed rod 22 rotates, it will drive the two crossbars 23 to rotate together. Connecting rods 24 are rotatably mounted on the mounting brackets 8 on both sides. The connecting rods 24 are vertical. A vertical rod 25 is slidably mounted on the 4th shaft, and a receiving cavity is provided on the connecting rod 24. The vertical rod 25 is slidably engaged with the receiving cavity. When the vertical rod 25 rotates, it will drive the connecting rod 24 to rotate together. The horizontal rod 23 is connected to the vertical rod 25 through a universal joint 26. When the horizontal rod 23 rotates, it will drive the vertical rod 25 to rotate together through the universal joint 26. The connecting rod 24 is connected to the shaft 9 through a first bevel gear pair 27. The first bevel gear pair 27 includes two meshing bevel gears, which are respectively fixed on the connecting rod 24 and the shaft 9.

[0045] Referring to the above, in the initial state, the total length of the fixed rod 22 and the two horizontal rods 23 is relatively short, as is the total length of the connecting rod 24 and the vertical rod 25. When the adjusting frames 4 on both sides slide synchronously to move away from each other, the two horizontal rods 23 slide synchronously in opposite directions, increasing the total length of the fixed rod 22 and the two horizontal rods 23. When the two column rods 7 slide synchronously downwards, the two connecting rods 24 slide downwards together, increasing the total length of the connecting rod 24 and the vertical rod 25. This drives the fixed rod 22 and the shaft 9 located on the intermediate mounting frame 8 to rotate synchronously, causing the fixed rod 22 to drive the two horizontal rods. The two rods 23 rotate together, and through the two universal joints 26, they drive the two vertical rods 25 to rotate together. The vertical rods 25 drive the connecting rods 24 to rotate together, and through the first bevel gear pair 27, they drive the shafts 9 to rotate together, so as to drive the three shafts 9 to rotate synchronously. Conversely, when the adjusting brackets 4 on both sides slide synchronously to approach each other, the two horizontal rods 23 slide synchronously in opposite directions, and the total length of the fixed rod 22 and the two horizontal rods 23 is shortened. When the two column rods 7 slide downward synchronously, the two connecting rods 24 slide upward together, and the total length of the connecting rods 24 and the vertical rods 25 is shortened.

[0046] like Figure 4 As shown, in some embodiments, a drive rod 28 is rotatably mounted on the frame 5. The drive rod 28 is vertical. A drive motor 29 with an output shaft connected to the drive rod 28 is mounted on the frame 5. The drive motor 29 is fixed on the frame 5. The two ends of the drive rod 28 are respectively connected to the fixed rod 22 and the shaft 9 through two second bevel gear pairs 30. The second bevel gear pairs 30 include two meshing bevel gears. The two bevel gears of one second bevel gear pair 30 are respectively fixed on the drive rod 28 and the shaft 9. The two bevel gears of the other second bevel gear pair 30 are respectively fixed on the drive rod 28 and the fixed rod 22.

[0047] Referring to the above, when in use, turn on the drive motor 29, the drive motor 29 works, the output shaft rotates, driving the drive rod 28 to rotate together, and through the two second bevel gear pairs 30, drive the fixed rod 22 and the shaft 9 to rotate together, so as to realize the synchronous rotation of the drive fixed rod 22 and the shaft 9 located on the intermediate mounting bracket 8.

[0048] like Figure 6 As shown, in some embodiments, the grinding wheel 10 is detachably mounted on the shaft 9;

[0049] Referring to the above, in actual use, the wear of the grinding wheel 10 will gradually increase over time. The detachable design makes it easy to replace the grinding wheel 10 to ensure the grinding effect.

[0050] like Figure 6 As shown, in some embodiments, the shaft 9 is provided with a groove 31, which is opened in the horizontal direction. The grinding wheel 10 is provided with a protrusion 32 that is inserted into the groove 31 and fixed on the grinding wheel 10. The shaft 9 is threaded with a locking nut 33 that abuts against the grinding wheel 10.

[0051] Referring to the above, in the initial state, the grinding wheel 10 is in the installed state, with the grinding wheel 10 completely located on the shaft 9, the protrusion 32 completely located in the groove 31, and the locking nut 33 in the tightened state, contacting and overlapping with the grinding wheel 10. When the shaft 9 rotates, the grinding wheel 10 is driven to rotate together through the cooperation of the protrusion 32 and the groove 31. When the grinding wheel 10 needs to be replaced, the locking nut 33 is loosened away from the shaft 9, so that the grinding wheel 10 moves horizontally away from the shaft 9, and the protrusion 32 exits the groove 31, thus disassembling the grinding wheel 10. Then, a new grinding wheel 10 is installed, with the protrusion 32 corresponding to and inserted into the groove 31, until the grinding wheel 10 is completely located on the shaft 9. Finally, the locking nut 33 is tightened onto the shaft 9 and contacting and overlapping with the grinding wheel 10, thus realizing the replacement of the grinding wheel 10.

[0052] like Figure 6 As shown, in some embodiments, the shaft 9 is provided with annular plates 34 spaced apart from the mounting bracket 8. The annular plates 34 are vertical and fixed on the shaft 9, and the grinding wheel 10 abuts and overlaps with the annular plates 34.

[0053] Referring to the above, when the grinding wheel 10 is installed, it will abut and overlap with the ring plate 34. The ring plate 34 limits the grinding wheel 10 to prevent it from contacting the mounting bracket 8, thereby avoiding friction damage between the grinding wheel 10 and the mounting bracket 8 when the grinding wheel 10 rotates. It also facilitates the quick positioning of the grinding wheel 10.

[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
