Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of boiler tube rows, and specifically relate to a 360-degree all-round automatic welding system for boiler tube rows. Background Art

[0002] Currently, the welding of boiler tube rows usually relies on manual or semi-automatic welding equipment. Technologies such as manual arc welding, TIG welding, and MIG / MAG welding are widely used in the welding of boiler tube rows. Although these methods can meet the welding requirements of boiler tube rows to a certain extent, there are still certain limitations in aspects such as the control of welding quality, work efficiency, and the stability of worker operation. Most traditional welding equipment is limited to a certain angle or range and cannot achieve 360-degree all-round automatic welding. Especially in the case of complex boiler tube row layouts, there are problems with high welding difficulty.

[0003] Although the existing boiler tube row welding technologies can complete welding tasks under certain conditions, there are multiple drawbacks in actual operation. First, the traditional welding method requires experienced welders to operate. This manual operation is not only inefficient, but also the welding quality is easily affected by the technical level of the workers and cannot be consistent. Second, the existing welding equipment usually can only weld local areas and cannot achieve 360-degree all-round automatic welding, resulting in some welding positions that cannot be smoothly completed in complex or narrow spaces, and it is difficult to guarantee the welding quality. Summary of the Invention

The lateral adjustment component includes a first push rod 20, and the output end of the first push rod 20 is fixedly connected to a sleeve rod 21.

[0045] Exemplarily, as Figures 1 to 7 shown, a controller 25 is fixedly connected to the upper surface of the second support plate 6.

[0046] Exemplarily, as Figures 1 to 7 shown, hinge joints 17 are provided on the outer walls of one sides of the fixed disk 1, the gear disk 10, and the support disk 12, and snap fasteners 18 are provided on the outer walls of the other sides of the fixed disk 1, the gear disk 10, and the support disk 12.

[0047] Exemplarily, as Figures 1 to 7 shown, a gasket 7 is fixedly connected inside the fixed disk 1, and a boiler tube bank 19 is provided on the inner wall of the gasket 7.

[0048] The following combines Figures 1 to 7 to illustrate the working principle of the 360-degree omnidirectional automatic welding system for the boiler tube bank according to the embodiments of the present invention:

[0049] First, open the buckle 18 so that the fixed disks 1, the toothed disks 10, and the support disks 12 on both the left and right sides are opened around the hinge. Then, close the fixed disk 1 around the boiler tube bank 19 and use the buckle 18 to fix the fixed disk 1 outside the boiler tube bank 19. The fixed disk 1 and the gasket 7 inside it form a composite structure of steel and rubber, enabling the fixed disk 1 to be firmly clamped outside the boiler tube row 19. Then, start the motor 4 through the controller 25. When the motor 4 starts, it drives the gear 13 to rotate. When the gear 13 rotates circumferentially around the toothed disk 10, it drives the motor 4 and the second support plate 6 to rotate. At the same time, the motor 4 drives the third rotating shaft 15 to rotate inside the second sliding groove 16 and drives the first rotating shaft 3 to rotate inside the first sliding groove 2 opened on the lower side of the fixed disk 1. When the second support plate 6 rotates, it drives the lower end of the second rotating shaft 14 to rotate inside the first sliding groove 2 opened on the upper side of the fixed disk 1. And when the motor 4 and the second support plate 6 rotate, they drive the first support plate 5 to rotate. Subsequently, the second support plate 6 drives the welding torch 8 to rotate 360 degrees around the boiler tube bank 19 and automatically welds the upper and lower boiler tube banks 19. During welding, the wire feeding mechanism 9 is used to feed wire to assist the welding torch 8 in welding.

[0050] When it is necessary to adjust the arc length of the welding arc, first control and turn on the first push rod 20 through the controller 25. When the first push rod 20 is turned on, it pushes the sleeve rod 21 to move. When the sleeve rod 21 moves, it drives the slider 22 to slide inside the sliding groove 23, thereby causing the welding torch 8 to slide left and right. When it is necessary to adjust the height of the welding torch 8, first control and turn on the second push rod 24 through the controller 25. When the second push rod 24 is turned on, it directly pushes the welding torch 8 to move up and down.

[0051] When choosing to install two welding torches 8 on the left and right sides of the fixed disk 1, the toothed disk 10, and the support disk 12 at the same time, turn on the motor 4 and the welding torch 8 simultaneously to weld the boiler tube bank 19, and it only takes half of the original time to complete one welding, thus achieving the effect of saving welding time.

[0052] The 360-degree omnidirectional automatic welding system for boiler tube rows according to the embodiments of the present invention can achieve 360-degree omnidirectional automatic welding of boiler tube rows. The welding torch can perform a complete rotational movement around the boiler tube rows, effectively covering complex and narrow welding spaces, ensuring the integrity and uniformity of welding, and avoiding the limitation of only partial welding in the prior art. This system supports the simultaneous operation of two welding torches. Compared with traditional single-welding-torch welding, it can save half of the time, thus significantly improving the overall efficiency of welding operations and reducing the production cycle. By using a motor drive and an automated control system, the welding process is highly automated, reducing the impact of manual operation on welding quality, thereby improving the consistency and stability of welding quality. This system is equipped with a flexible welding arc adjustment function. Users can easily adjust the arc length and height of the welding torch through the control system to ensure precise control of welding parameters, improve welding quality, and adapt to different welding requirements. Due to the full-automatic control, the heat input, welding speed, and weld bead shape can be better controlled during the welding process, which helps to improve the quality and precision of the welded joints and avoid human errors in manual welding.

[0053] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
