For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0025] Please refer to the attached Figure 1 To Attachment Figure 3 The utility model describes a suction anchor cylinder welding device.

[0026] like Figure 1 and Figure 2As shown, the suction anchor cylinder welding device in the utility model includes a first slide rail 6 and a second slide rail 7 arranged in parallel, a turntable 2 is arranged between the first slide rail 6 and the second slide rail 7, and also includes a welding assembly 1, the welding assembly 1 is mounted on the turntable 2, one end of the welding assembly 1 is slidably arranged on the first slide rail 6, and the other end of the welding assembly 1 is slidably arranged on the second slide rail 7, the first cylinder group 3 and the second cylinder group 4 are horizontally placed on the turntable 2, a welding piece 15 is lifted and lowered on the welding assembly 1, the turntable 2 rotates the first cylinder group 3 and the second cylinder group 4, and the welding piece 15 welds the first cylinder group 3 and the second cylinder group 4.

[0027] By horizontally placing the first cylinder group 3 and the second cylinder group 4 on the rotating tire 2, a welding piece 15 is lifted and lowered on the welding assembly 1, the rotating tire 2 rotates the first cylinder group 3 and the second cylinder group 4, and the welding piece 15 welds the first cylinder group 3 and the second cylinder group 4. The horizontal welding of the first cylinder group 3 and the second cylinder group 4 not only reduces the difficulty and cost of construction, but also improves the accuracy and efficiency of cylinder welding.

[0028] Further, if Figures 1 to 3 As shown, the first cylinder group 3 includes a first cylinder 31, a second cylinder 32, a third cylinder 33, a fourth cylinder 34 and a fifth cylinder 35. The first cylinder 31, the second cylinder 32, the third cylinder 33, the fourth cylinder 34 and the fifth cylinder 35 are placed on the tire 2 in sequence along the length direction of the first slide rail 6 and the second slide rail 7. The welding assembly 1 moves along the first slide rail 6 and the second slide rail 7 so that the welding part 15 welds the first cylinder 31, the second cylinder 32, the third cylinder 33, the fourth cylinder 34 and the fifth cylinder 35 in sequence.

[0029] Further, if Figure 1 and Figure 3 As shown, the second cylinder group 4 includes a sixth cylinder 41 and a seventh cylinder 42. After the sixth cylinder 41 and the seventh cylinder 42 are vertically welded, they are horizontally placed on the rotating tire 2, and the welding assembly 1 moves along the first slide rail 6 and the second slide rail 7 to weld one of the sixth cylinder 41 or the seventh cylinder 42 to the first cylinder group 3.

[0030] Further, if Figure 1 and Figure 3As shown, the third cylinder group 5 is also included, and the third cylinder group 5 includes an eighth cylinder 51, a ninth cylinder 52 and a tenth cylinder 53. When the first cylinder group 3, the second cylinder group 4 and the third cylinder group 5 are connected, the sixth cylinder 41 and the seventh cylinder 42 in the second cylinder group 4 are firstly welded vertically, and then the eighth cylinder 51, the ninth cylinder 52 and the tenth cylinder 53 in the third cylinder group 5 are welded vertically, and then the third cylinder group 5 is overlapped on the second cylinder group 4, and the third cylinder group 5 and the second cylinder group 4 are welded vertically. At the same time, the first cylinder 31, the second cylinder 32, the third cylinder 33, the fourth cylinder 34 and the fifth cylinder 35 are placed on the rotating tire 2 in sequence, and the welding assembly 1 performs horizontal welding on the first cylinder 31, the second cylinder 32, the third cylinder 33, the fourth cylinder 34 and the fifth cylinder 35 on the rotating tire 2. After the vertical welding of the second cylinder group 4 and the third cylinder group 5 is completed, the hoisting equipment places the second cylinder group 4 and the third cylinder group 5 on the rotating tire 2, and the welding assembly 1 performs horizontal welding on the first cylinder group 3 and the second cylinder group 4 to achieve the welding of the first cylinder group 3, the second cylinder group 4 and the third cylinder group 5. In this embodiment, the height of the first cylinder group 3 is 12m, the height of the second cylinder group 4 is 3m, and the height of the third cylinder group 5 is 6m. During the welding process, a cross beam is placed in the first cylinder group 3, the second cylinder group 4 and the third cylinder group 5 for support to prevent the lower cylinder from being deformed by pressure during the horizontal welding process.

[0031] The first cylinder group 3 and the second cylinder group 4 are welded horizontally to reduce high-altitude operations. First, during the vertical welding construction process, as the cylinder construction height continues to increase, up to 22 meters, a lot of scaffolding needs to be set up, and the high-altitude operations gradually increase. After horizontal welding, the highest construction height is only 10 meters, which reduces the number of high-altitude operations and reduces the operation risk. Secondly, after the main construction of the suction anchor is completed, the casting ear needs to be welded. The horizontal method can reduce the number of scaffoldings set up when welding the casting ear, reduce the investment of funds, and reduce the difficulty of welding. Finally, vertical construction is adopted. When the segment is welded, it is difficult to control the precision. When the horizontal construction is adopted, the segment can be limited near the tire 2 when the segment is welded, which greatly improves the control of the precision. After the vertical construction is changed to horizontal, the original 22m high-altitude operation is reduced to 10m, reducing the risk of construction. At the same time, the low-altitude operation enhances the precision control in the assembly process, greatly improving the success rate of assembly.

[0032] Further, if Figure 1As shown, the welding assembly 1 includes a first support assembly 11 and a second support assembly 12. The first support assembly 11 is slidably arranged on the first guide rail, and the second support assembly 12 is slidably arranged on the second guide rail. A support frame 13 is lifted and lowered between the first support assembly 11 and the second support assembly 12, and the welding piece 15 is lifted and lowered on the support frame 13. Specifically, the first support assembly 11 includes a first bracket 111 and a second bracket 112. The first bracket 111 is movably arranged on the first slide rail 6, and the second bracket 112 is lifted and lowered on the first bracket 111. The end of the second bracket 112 away from the first bracket 111 is connected to the support frame 13. The second support assembly 12 includes a third bracket 121 and a fourth bracket 122. The third bracket 121 is movably arranged on the second slide rail 7, and the fourth bracket 122 is lifted and lowered on the third bracket 121. The end of the fourth bracket 122 away from the third bracket 121 is connected to the support frame 13. By providing the first supporting assembly 11 and the second supporting assembly 12 , the position of the welding assembly 1 can be adjusted, and the height of the welding assembly 1 can be adjusted to facilitate welding of the first cylinder group 3 and the second cylinder group 4 .

After placement, the welding assembly 1 moves along the first slide rail 6 and the second slide rail 7 to weld the first cylinder 31, the second cylinder 32, the third cylinder 33, the fourth cylinder 34 and the fifth cylinder 35 in turn. After the first cylinder group 3 is welded, the welding assembly 1 moves along the first slide rail 6 and the second slide rail 7 to make room for placing the second cylinder group 4 and the third cylinder group 5 on the rotating tire 2. After placement, the rotating tire drives the first cylinder group 3, the second cylinder group 4 and the third cylinder group 5 to rotate, and the welding assembly 1 moves along the first slide rail 6 and the second slide rail 7 to the annular seam position of the first cylinder group 3 and the second cylinder group 4, and the welding part 15 is raised and lowered to the welding position for annular seam welding.
