[0002] A wind turbine tower, or simply wind turbine tower, is the tower of a wind turbine generator. It primarily serves a supporting function within the wind turbine generator set, while also absorbing vibrations from the unit. Internal accessories, as the name suggests, are those installed inside the wind turbine tower. These come in various types, such as ladders, cable trays, cable clamps, maintenance platforms, and lifting platforms. The maintenance platform provides standing space for workers and space to operate and maintain equipment. It typically includes a support frame, side rails, and a top plate. During production, multiple I-beam frames are assembled and welded to form the support frame; multiple curved plates are assembled and welded onto the support frame to form the side rails; and multiple support plates are assembled and welded onto the support frame and side rails to form the top plate. The multiple support plates are listed in the instruction manual. Figure 1 As shown in the diagram, in the prior art, the welding of the support plate is usually done manually.

[0036] 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.

[0037] like Figures 1-14 As shown in one embodiment of this application, an automated welding equipment for internal accessories of a wind power generation tower includes:

[0038] A frame 1 has a support frame 2 slidably mounted on it. The support frame 2 slides horizontally. The frame 1 has a loading station, a first welding station, a second welding station, a third welding station, and a unloading station arranged sequentially along the Y-axis. The frame 1 also has a first fixing frame 3, a second fixing frame 4, and a third fixing frame 5 arranged sequentially. The first fixing frame 3, the second fixing frame 4, and the third fixing frame 5 are all fixed on the frame 1. The first fixing frame 3 corresponds to the first welding station, the second fixing frame 4 corresponds to the second welding station, and the third fixing frame 5 corresponds to the third welding station. The support frame 2 is equipped with a clamping mechanism, multiple positioning blocks 6, and multiple electromagnets 7. The clamping mechanism is used to fix or release the edge. In this embodiment, there are two positioning blocks 6, both of which are fixed on the support frame 2. The positioning blocks 6 correspond to the through slots on the support plate. The multiple electromagnets 7 are all fixed on the support frame 2. The electromagnets 7 are used to fix or release the support plate.

[0039] The first welding head 8 and the six second welding heads 9 are all movably mounted on the first fixed frame 3. The first welding head 8 and the six second welding heads 9 move in the horizontal direction. The first fixed frame 3 is provided with a driving component and a driving part. The driving component drives the first welding head 8 to move in a circular motion, and the driving part drives the six second welding heads 9 to move synchronously in the X-axis direction.

[0040] The third welding head 10 is movably mounted on the second fixed frame 4. The third welding head 10 moves horizontally. The second fixed frame 4 is equipped with a driving mechanism, which drives the third welding head 10 to move along a rectangular trajectory.

[0041] The fourth welding head 11 is movably mounted on the third fixed frame 5. The fourth welding head 11 moves in the horizontal direction. The third fixed frame 5 is provided with a driving component, which drives the fourth welding head 11 to move in the Y-axis direction.

[0042] In its initial state, the support frame 2 is located at the loading station. During production, the operation and maintenance platform assembles and welds multiple I-beams into a support frame, assembles and welds multiple curved plates onto the support frame to form a perimeter, and then places the support frame horizontally onto the support frame 2. The perimeter is fixed by a clamping mechanism, and multiple support plates are then... Figure 1As shown, multiple support plates, assembled on the support frame and perimeter, form one circumferential seam, one rectangular seam, one transverse seam, and six longitudinal seams. The first welding head 8 corresponds to the circumferential seam, the six second welding heads 9 correspond to the six longitudinal seams, the third welding head 10 corresponds to the rectangular seam, and the fourth welding head 11 corresponds to the transverse seam. Positioning blocks 6 are aligned with the through slots on the support plates, energizing multiple electromagnets 7 to fix the support plates for subsequent welding. Then, the carrier frame 2 is driven to slide from the loading station to the first welding station. The driving component drives the first welding head 8 to move circumferentially, thereby welding the circumferential seam of the support plate. The driving unit drives the six second welding heads 9 to move synchronously along the X-axis, thereby welding the six longitudinal seams of the support plate. The support frame 2 is driven to slide from the first welding station to the second welding station. The third welding head 10 is driven to move along a rectangular trajectory by the driving mechanism, thereby welding the rectangular seam of the support plate. Then, the support frame 2 is driven to slide from the second welding station to the third welding station. The fourth welding head 11 is driven to move along the Y-axis by the driving component, thereby welding the transverse seam of the support plate. This achieves the welding of the support plate, so that multiple support plates form a top plate, and the support frame, the surrounding edge, and the top plate form an operation and maintenance platform. Finally, the support frame 2 is driven to slide from the third welding station to the unloading station. The surrounding edge is released from the clamping mechanism, the multiple electromagnets 7 are de-energized, the support plate is released from the clamping mechanism, and the operation and maintenance platform is removed from the support frame 2.

[0043] In summary, when using this application, the circumferential and longitudinal seams of the support plate are welded first, then the rectangular seam of the support plate is welded, and finally the transverse seam of the support plate is welded, so as to realize the automated assembly line welding of the support plate, improve the welding efficiency, and thus be more practical.

[0044] like Figures 3-5 As shown, in some embodiments, the clamping mechanism includes a ring plate 12 rotatably mounted on the support frame 2. The ring plate 12 is horizontal and has multiple strip grooves 13. The multiple strip grooves 13 are all horizontal and arranged in a circular array. The strip grooves 13 have relatively distributed initial points and limit points. The support frame 2 is rotatably mounted with multiple arc rods 14 that abut against and overlap with the surrounding edge. The arc rods 14 are horizontal and slide in the horizontal direction. The number of arc rods 14 is the same as the number of strip grooves 13. The arc rods 14 are provided with protrusions 15 that slide with the strip grooves 13. The protrusions 15 are vertical and fixed on the arc rods 14.

[0045] Referring to the above, in the initial state, the multiple arc-shaped rods 14 are all away from the axis of the ring plate 12, and the protrusions 15 are located at the initial point of the strip groove 13. When the support frame is placed horizontally on the bearing frame 2, the ring plate 12 is driven to rotate clockwise, and the multiple protrusions 15 slide from multiple initial points to multiple limit points, thereby driving the multiple arc-shaped rods 14 to slide synchronously to a point close to the axis of the ring plate 12, until the multiple arc-shaped rods 14 all abut against and overlap with the edge, so as to fix the edge. Conversely, the ring plate 12 is driven to rotate counterclockwise, and the multiple protrusions 15 slide from multiple limit points to multiple initial points, thereby driving the multiple arc-shaped rods 14 to slide synchronously to a point away from the axis of the ring plate 12, until the multiple arc-shaped rods 14 all move away from the edge, so as to release the edge from fixation.

[0046] like Figure 5 As shown, in some embodiments, an external gear ring 16 is provided on the ring plate 12. The external gear ring 16 is horizontal and fixed on the ring plate 12. A shaft 17 is rotatably provided on the support frame 2. The shaft 17 is vertical. A fixed gear 18 that meshes with the external gear ring 16 is provided on the shaft 17. The fixed gear 18 is horizontal and fixed on the shaft 17.

[0047] Referring to the above, when in use, the shaft 17 is driven to rotate, which in turn drives the fixed gear 18 to rotate. The external gear ring 16 will rotate due to meshing and drive the ring plate 12 to rotate as well. In actual use, a motor should be installed on the support frame 2 and the output shaft of the motor should be connected to the shaft 17. The shaft 17 is driven to rotate by the operation of the motor, which makes it more convenient to use.

[0048] like Figures 6-9 As shown, in some embodiments, the driving component includes a ring rail 19 disposed on the first fixed frame 3. The ring rail 19 is horizontal and fixed on the first fixed frame 3. An internal gear ring 20 is disposed on the ring rail 19. The internal gear ring 20 is horizontal and fixed on the ring rail 19. A driving frame 21 is movably disposed on the ring rail 19. The driving frame 21 moves in the horizontal direction. A roller and a driving gear 22 are rotatably disposed on the driving frame 21. The driving gear 22 is horizontal. The roller rolls and overlaps with the ring rail 19. The driving gear 22 meshes with the internal gear ring 20. In this embodiment, a motor is fixed on the driving frame 21. The output shaft of the motor is vertical and fixedly connected to the driving gear 22. A first welding head 8 is disposed on the driving frame 21.

[0049] Referring to the above, when in use, the motor works, the output shaft rotates, which drives the drive gear 22 to rotate. The drive gear 22 revolves due to meshing and drives the drive frame 21 to make circular motion on the ring rail 19, so as to drive the first welding head 8 to make circular motion. In this process, the roller component can not only make the movement of the drive frame 21 smoother, but also guide and limit the drive frame 21.

[0050] like Figures 6-9As shown, in some embodiments, two relatively distributed annular grooves 23 are constructed on the ring rail 19. The two annular grooves 23 are both horizontal and are located on the outer and inner sides of the ring rail 19, respectively. An internal toothed ring 20 is disposed in one of the annular grooves 23. The roller component includes a plurality of first rollers 24 and second rollers 25. The first rollers 24 and second rollers 25 are both horizontal. The first rollers 24 roll over the other annular groove 23, and the second rollers 25 roll over the ring rail 19.

[0051] Referring to the above, when the drive frame 21 makes a circular motion on the ring rail 19, multiple first rollers 24 roll together in the annular groove 23, and multiple second rollers 25 abut against and overlap with the ring rail 19 to guide and limit the drive frame 21.

[0052] like Figure 10 As shown, in some embodiments, the drive unit includes two first slide rods 26 and two second slide rods 27 that are slidably disposed on the first fixed frame 3. Both the first slide rods 26 and the second slide rods 27 slide along the X-axis. A first forward / reverse lead screw 28 and a second forward / reverse lead screw 29 are rotatably disposed on the first fixed frame 3 and are connected by a differential gear pair 30. Both the first forward / reverse lead screw 28 and the second forward / reverse lead screw 29 are horizontal. The differential gear pair 30 includes two meshing gears that are both vertical and have different diameters, and are respectively fixed to the first forward / reverse lead screw 28. On the second positive and negative lead screw 29, when the first positive and negative lead screw 28 rotates, the second positive and negative lead screw 29 is driven to rotate synchronously and differentially through the differential gear pair 30. That is, the speed of the first positive and negative lead screw 28 is greater than the speed of the second positive and negative lead screw 29. The two first slide rods 26 are respectively threaded with the positive and negative thread sections of the first positive and negative lead screw 28, and the two second slide rods 27 are respectively threaded with the positive and negative thread sections of the second positive and negative lead screw 29. The two second welding heads 9 are respectively set on the two second slide rods 27, and the remaining four second welding heads 9 are in pairs and are respectively set on the two first slide rods 26.

[0053] Referring to the above, in the initial state, both first slide rods 26 are in their initial positions and are in contact with each other, and both second slide rods 27 are in their initial positions. During use, the first forward and reverse screws 28 are driven to rotate, and the two first slide rods 26 slide synchronously in opposite directions to move away from each other due to the action of the forward and reverse threads, thereby driving the four second welding heads 9 to move synchronously. At the same time, the second forward and reverse screws 29 are driven to rotate synchronously at different speeds through the differential gear pair 30, and the two second slide rods 27 slide synchronously in opposite directions to move away from each other due to the action of the forward and reverse threads, thereby driving the two second welding heads 9 to move synchronously. The sliding stroke of the first slide rod 26 is greater than the sliding stroke of the second slide rod 27, so as to drive the six second welding heads 9 to move synchronously along the X-axis.

[0054] like Figures 11-13As shown, in some embodiments, the driving mechanism includes a fixed rod 31 mounted on a second fixed frame 4. The fixed rod 31 is horizontal and fixed on the second fixed frame 4. A guide rod 32 is slidably mounted on the fixed rod 31. The guide rod 32 is horizontal and slides along the length of the fixed rod 31. A slider 33 is slidably mounted on the guide rod 32. The slider 33 slides along the length of the guide rod 32. A driving block 34 is rotatably mounted on the second fixed frame 4. A limit rod 35 is slidably mounted on the driving block 34, and a return spring 36 is provided between the two. The limit rod 35 slides in the horizontal direction. The return spring 36 is horizontal and its two ends are fixedly connected to the driving block 34 and the limit rod 35, respectively. The free end of the limit rod 35 is hinged to the slider 33. A third welding head 10 is mounted on the slider 33.

[0055] Referring to the above, in the initial state, the guide rod 32 is located at the initial position of the fixed rod 31, the slider 33 is located at the initial position of the guide rod 32, the limiting rod 35 is located at the initial position, and the return spring 36 is in its natural state. During use, the drive block 34 is driven to rotate, causing the limiting rod 35, the slider 33, and the guide rod 32 to move together. During this process, the limiting rod 35 first slides to its limit position, the return spring 36 is compressed, and the guide rod 32 slides to the middle position of the fixed rod 31. Then, the limiting rod 35 slides to its initial position, the return spring 36 returns to its natural state, and the guide rod 32 slides to the limit position of the fixed rod 31. The limit rod 35 and the return spring 36 then repeat the movement state more than three times. In the first process, the slider 33 first slides to the middle position of the guide rod 32, and then slides to the limit position of the guide rod 32. In the second process, the guide rod 32 first slides to the middle position of the fixed rod 31, and then slides to the limit position of the fixed rod 31. In the third process, the slider 33 first slides to the middle position of the guide rod 32, and then slides to the initial position of the guide rod 32. Thus, the slider 33 completes a complete rectangular trajectory movement and drives the third welding head 10 to move together, so as to drive the third welding head 10 to move along the rectangular trajectory.

[0056] like Figure 15 As shown, in some embodiments, the driving component includes a movable block 37 slidably disposed on the third fixed frame 5, the movable block 37 sliding along the Y-axis direction, an adjusting block 38 disposed on the movable block 37, a fourth welding head 11 disposed on the adjusting block 38, and a screw 39 threaded through the movable block 37 rotatably disposed on the third fixed frame 5, the screw 39 being in the horizontal direction.

[0057] Referring to the above, when in use, the screw 39 is driven to rotate, and the moving block 37 will slide along the Y-axis due to the thread action, and drive the fourth welding head 11 to move together, so as to drive the fourth welding head 11 to move along the Y-axis.

[0058] like Figure 15As shown, in some embodiments, the adjusting block 38 is slidably disposed on the moving block 37. The adjusting block 38 slides in the vertical direction. The third fixed frame 5 is provided with a linkage on the adjusting block 38. When the moving block 37 slides, the adjusting block 38 is driven to slide intermittently back and forth through the linkage. The intermittent back and forth sliding here means that the adjusting block 38 first slides along the Y-axis, then slides along the trapezoidal trajectory, then continues to slide along the Y-axis, then slides along the trapezoidal trajectory, and finally continues to slide along the Y-axis.

[0059] Referring to the above, when the moving block 37 slides, the linkage drives the adjusting block 38 to slide intermittently. When the adjusting block 38 slides along the trapezoidal trajectory, the fourth welding head 11 can avoid the rectangular trajectory that has been previously welded, thereby avoiding repeated welding.

[0060] like Figure 15 As shown, in some embodiments, the linkage includes a fixing plate 40 disposed on the third fixing frame 5. The fixing plate 40 is horizontal and fixed on the third fixing frame 5. A guide groove 41 is provided on the fixing plate 40. The guide groove 41 includes a first straight groove, a first trapezoidal groove, a second straight groove, a second trapezoidal groove and a third straight groove that are connected in sequence. A protrusion 42 that slides with the guide groove 41 is provided on the adjusting block 38. The protrusion 42 is horizontal and fixed on the adjusting block 38.

[0061] Referring to the above, in the initial state, the protruding post 42 is located in the first straight groove, and the adjusting block 38 is located in the initial position. When the moving block 37 slides, the protruding post 42 passes through the first straight groove, the first trapezoidal groove, the second straight groove, the second trapezoidal groove and the third straight groove in sequence, thereby driving the adjusting block 38 to slide intermittently back and forth.

[0062] 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.
