Description

Technical Field

[0001] The present application relates to the technical field of wind power tower processing equipment, and particularly relates to an efficient segmented welding device for wind power tower cylinders. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind is a pollution-free energy source. Using wind power generation is very environmentally friendly and can generate a large amount of electrical energy. Therefore, more and more countries attach greater importance to wind power generation. A wind power tower mainly supports a tall steel structure used for a wind power generating set. The structure of a wind power tower is generally formed by welding multiple steel plates into a cylinder, with flange plates welded at both ends of the cylinder. Adjacent cylinders are fixedly connected through two flange plates, bolts, and nuts. Therefore, when connecting the flange plates at both ends of a single-section cylinder, welding equipment is required for welding.

[0003] In the existing welding of cylinders, generally, the cylinder is placed on a workbench that can rotate and support it, and then the flange is fitted to the end of the cylinder. First, spot welding is used to preliminarily weld several fixed points to temporarily fix the flange to the cylinder. Then, the cylinder is rotated, and a welding device is used to perform circumferential welding on the connection part between the cylinder and the flange, thereby effectively fixing the cylinder and the flange. Due to the huge size of the wind power tower, the structures of the cylinder and the flange are also relatively large. Therefore, generally, a gantry crane is used to hoist the flange and lap it with the cylinder, and the position of the flange is adjusted by relying on the gantry crane during welding. The hoisting method makes the flange prone to shaking and displacement, resulting in deviations in the welding connection points between the cylinder and the flange during preliminary spot welding. After the final circumferential welding and fixation, the deviation between adjacent cylinders during splicing is relatively large, affecting the overall quality of the power generation tower. Therefore, the present application proposes an efficient segmented welding device for wind power tower cylinders. Summary of the Invention

[0004] The purpose of the present application is to provide an efficient segmented welding device for wind power tower cylinders to solve the problem of poor welding quality of power generation towers in the existing hoisting welding.

Detailed implementation manners

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application.

[0040] As Figures 1 - 9As shown in the figure, an efficient segmented wind power tower barrel welding device proposed by an embodiment of the present application includes: a placement table 1 for rotatably supporting the tower barrel. One end of the placement table 1 is provided with a mounting plate 2. A robotic arm 3 is provided on the mounting plate 2 through a bracket, and a welding machine 4 is provided at the free end of the robotic arm 3; a mounting seat 5 is slidably arranged on the mounting plate 2. A shaft rod 6 is rotatably penetrated through the mounting seat 5, and a driving part 7 for driving the shaft rod 6 to rotate is arranged on the mounting seat 5; a mounting column 8 is coaxially arranged at one end of the shaft rod 6. Two collar rings 9 are slidably arranged on the mounting column 8. A plurality of support rods 10 distributed in a ring are hinged on each of the two collar rings 9. The support rods 10 on the two collar rings 9 are in pairs. The free ends of the corresponding two support rods 10 are hinged with a support plate 11. An adjusting part 12 for adjusting the synchronous reverse movement of the two collar rings 9 is arranged on the mounting column 8; a plurality of clamping blocks 13 are respectively slidably arranged on a plurality of support plates 11. An adjusting part 14 for adjusting the synchronous sliding of the plurality of clamping blocks 13 is arranged on the shaft rod 6. When welding the barrel and the flange, place the barrel on the placement table 1 (it can be lifted by a crane). The placement table 1 rotatably supports the barrel. Then, sleeved the flange on a plurality of support plates 11 (it can be lifted by a crane. After the flange is sleeved on a plurality of support plates 11, immediately release the lifting). Preferably, the support plate 11 is an arc-shaped plate. Then, slide the mounting seat 5, so that the mounting column 8 and a plurality of support plates 11 are coaxially placed inside the barrel. Adjust the two collar rings 9 to move synchronously and reversely through the adjusting part 12. When the two collar rings 9 approach synchronously, the corresponding two support rods 10 abut against the support plate 11 away from the mounting column 8, and a plurality of support plates 11 move away from the mounting column 8 synchronously. A plurality of support plates 11 all abut against the inner wall of the barrel, and use the abutting friction force to fix the mounting column 8 and the barrel. After the barrel is fixed, adjust the plurality of clamping blocks 13 to slide along a plurality of support plates 11 respectively through the adjusting part 14. When the plurality of clamping blocks 13 slide synchronously, the abutting flange slides along a plurality of support plates 11, and slides close to the barrel, and applies a certain abutting force to the flange. Use the abutting friction force to effectively fit the barrel and the flange. When the flange fits the barrel, not only the end faces of the two are effectively overlapped, but also the two are in a coaxial state, effectively aligned. Then, drive the shaft rod 6 to rotate through the driving part 7, so as to drive the mounting column 8 to rotate, so as to drive the barrel and the flange to rotate synchronously. When the barrel and the flange rotate, use the robotic arm 3 to adjust the angular position, so that the welding machine 4 performs circumferential welding on the connection point of the barrel and the flange. The overall structure of the device uses a plurality of support plates 11 to support the flange, and then coaxially places a plurality of support plates 11 inside the barrel. A plurality of support plates 11 expand and abut against the inner wall of the barrel, so as to fix the barrel. At this time, the barrel and the flange are in a coaxial state. Then, use the synchronous same-direction sliding of a plurality of clamping blocks 13 to push the flange and the barrel to overlap, and use the abutting force to effectively and preliminarily fix the barrel and the flange (such as Figure 4As shown in the figure, then perform circumferential welding for fixation. There is no need to perform preliminary spot welding for temporary fixation, and circumferential welding can be directly carried out. At the same time, the alignment connection effect between the two is good, the displacement deviation is small, ensuring the welding quality of the cylinder and the flange, thereby improving the overall quality of the power generation tower.

[0041] As Figure 7 shown, in some embodiments, the adjusting member 12 includes: a bidirectional threaded rod 1201, a cavity is formed in the mounting post 8, and the bidirectional threaded rod 1201 coaxially rotates through the mounting post 8; two movable blocks 1202 are respectively threadedly sleeved at both ends of the bidirectional threaded rod 1201, a through groove 1203 is formed through the mounting post 8, and a connecting rod 1204 that movably penetrates through the through groove 1203 is connected between the two movable blocks 1202 and the two collar rings 9 respectively. Twist the bidirectional threaded rod 1201 to rotate. Under the action of the double thread, and the sliding limit of the connecting rod 1204 and the through groove 1203, the two movable blocks 1202 are driven to move synchronously and in opposite directions. When the two movable blocks 1202 move synchronously and in opposite directions, the connection of the connecting rod 1204 is used to drive the two collar rings 9 to slide synchronously and in opposite directions.

[0042] As Figure 8 shown, in some embodiments, the adjusting part 14 includes: a sleeve 1401, which is movably sleeved on the shaft rod 6, and a plurality of telescopic rods 1402 are arranged in an array on the outer surface of the sleeve 1401, and the end parts of the plurality of telescopic rods 1402 are respectively connected to a plurality of clamping blocks 13; a sleeve 1403, which is coaxially rotatably connected to the sleeve 1401 and threadedly sleeved on the shaft rod 6. Twist the sleeve 1403 to rotate and move, thereby driving the sleeve 1401 to slide. When the sleeve 1401 slides, the plurality of telescopic rods 1402 respectively drive the plurality of clamping blocks 13 to move. It should be noted that an annular groove is formed at one end of the sleeve 1401, and an annular block that is rotationally matched with the annular groove is constructed at one end of the sleeve 1403. The longitudinal sections of the annular groove and the annular block are both constructed as T-shaped, and the longitudinal section of the clamping block 13 is constructed as I-shaped. The clamping block 13 can only slide horizontally on the support plate 11. Due to the axial telescopic characteristic of the telescopic rod 1402, after the position of the support plate 11 changes, the sleeve 1401 can still drive the plurality of clamping blocks 13 to slide synchronously and in the same direction when moving.

[0043] As Figure 5As shown, in some embodiments, the support plate 11 includes a first plate body 1101 and a second plate body 1102 connected to each other. The clamping block 13 is slidably arranged on the second plate body 1102. A plurality of balls 15 are arrayed and rotatably inserted on the outer surface of the second plate body 1102. Preferably, the first plate body 1101 is lapped with the inner wall of the cylinder body, and the flange sleeve is arranged on the second plate body 1102. After the whole support plate 11 moves, the first plate body 1101 is lapped with the inner wall of the cylinder body, and the second plate body 1102 is also lapped with the inner wall of the flange. By arraying and rotatably inserting a plurality of balls 15 on the outer surface of the second plate body 1102, the balls 15 replace the second plate body 1102 to lap with the inner wall of the flange, which can not only ensure effective coaxial alignment between the cylinder body and the flange, but also reduce the frictional resistance of the flange sliding along the second plate body 1102, making the sliding smoother and the adjustment more convenient.

[0044] As Figure 6 shown, in some embodiments, the driving part 7 includes: a driven gear 701 fixedly arranged on the shaft rod 6; a motor 702 arranged on the mounting seat 5, and a transmission gear 703 fixedly arranged on the output shaft of the motor 702 and meshing with the teeth of the driven gear 701. When the motor 702 does work, its output shaft drives the transmission gear 703 to rotate, and by using the meshing of the teeth of the transmission gear 703 and the driven gear 701, the shaft rod 6 can be driven to rotate.

[0045] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, four support seats 16 distributed in a rectangle are arranged on the placing table 1. A supporting wheel 17 is rotatably arranged on the support seat 16. The cylinder body is placed on the four supporting wheels 17. The four supporting wheels 17 support the cylinder body, and at the same time do not affect the normal rotation of the cylinder body, and it is more convenient to hoist and place the cylinder body.

[0046] As Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, a T-shaped slide rail 18 is arranged on the mounting plate 2. A sliding seat 19 is arranged on the T-shaped slide rail 18. The mounting seat 5 is arranged on the sliding seat 19. A first hydraulic cylinder 20 is connected between the mounting plate 2 and the sliding seat 19. When the first hydraulic cylinder 20 does work, its piston end drives the sliding seat 19 to slide along the T-shaped slide rail 18, so as to drive the mounting seat 5 to move.

[0047] As Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, two vertical rods 21 are provided on the sliding seat 19, the mounting seat 5 is slidably sleeved on the two vertical rods 21, and a second hydraulic cylinder 22 is provided between the sliding seat 19 and the mounting seat 5. After cylinders of different sizes are placed on the four supporting wheels 17, the axial center heights of different cylinders are different. The mounting seat 5 is slidably sleeved on the two vertical rods 21, and the second hydraulic cylinder 22 does work, and its piston end extends or contracts, so as to achieve the effect of adjusting the axial center height of the shaft rod 6, so that when processing cylinders of different sizes, the axial center height of the shaft rod 6 can be adjusted to be the same as the axial center height of the cylinder, which is convenient for the coaxial alignment of the cylinder and the flange, thereby improving the versatility and practicability of the whole device.

[0048] As Figure 4 and Figure 9 shown, in some embodiments, slots 23 are opened at both ends of the placing table 1, and one end of the mounting plate 2 is provided with an insertion plate 24 that is inserted and matched with the slots 23. By using the insertion and matching of the insertion plate 24 and the slots 23, the placing table 1 and the mounting plate 2 are detachably connected. After the flange at one end is welded, there is no need to move the cylinder to adjust its orientation, and only the mounting plate 2 needs to be moved to the other end of the cylinder. At the same time, the insertion and matching of the slots 23 and the insertion plate 24 facilitate the alignment of the placing table 1 and the mounting plate 2, and facilitate the coaxial alignment of the axial center of the shaft rod 6 and the axial center of the cylinder.

[0049] As Figure 1 , Figure 2 and Figure 9 shown, in some embodiments, wheels 25 are provided at the four corners of the bottom of the mounting plate 2, threaded holes are penetrated through the insertion plate 24, and screw rods 26 that are threadedly matched with the threaded holes are threadedly penetrated through both ends of the placing table 1. By providing the wheels 25, it is more convenient to move the mounting plate 2. After the position of the mounting plate 2 is adjusted, after the insertion plate 24 is inserted into the slot 23, the screw rod 26 is twisted and threadedly inserted into the threaded hole on the insertion plate 24, so as to achieve the effect of fixing the placing table 1 and the mounting plate 2.

[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
