Description

Technical Field

[0001] This utility model relates to the field of tank welding technology, and in particular to a tank welding positioning device. Background Technology

[0002] Tank welding refers to the process of connecting the various parts of a tank into a whole by molten metal. It is mainly used to manufacture sealed metal structures such as storage tanks, pressure vessels, and transport tanks. Its core function is to ensure the sealing, pressure resistance, and durability of the tank. It is widely used in petrochemical, food and pharmaceutical, and energy storage and transportation fields. During welding, the appropriate method, such as electric arc welding or argon arc welding, must be selected according to the material, and process standards must be strictly followed to prevent defects such as weld porosity and cracks. For example, liquefied natural gas storage tanks can withstand temperatures as low as -162°C without leakage through multi-layer welding technology, making it a key manufacturing link in energy infrastructure.

[0003] Traditional tank welding positioning devices cannot adapt to various tank sizes, lack flexibility, and struggle to accurately position welding parts on tanks of different sizes. This leads to increased misalignment of components, potentially causing problems such as rough weld surfaces, uneven width, or abnormal reinforcement height. These issues directly affect the mechanical properties and sealing performance of the weld, significantly reducing the service life of the welded parts and even posing a risk of brittle fracture. Furthermore, unstable supports can cause uneven distribution of thermal stress during welding, leading to structural deformation or residual stress accumulation, affecting the dimensional consistency and long-term durability of the tank.

[0004] Therefore, in view of the problems that the traditional tank welding positioning device cannot adapt to various tank sizes and cannot be flexibly adjusted, resulting in decreased docking accuracy, reduced weld quality, and increased structural deformation and internal stress, a tank welding positioning device that can be flexibly adjusted can be designed to solve the above problems. Utility Model Content

According to the size of the tank, the height adjustment assembly outputs power to the slider 4, so that the slider 4 moves to a suitable height. Then, the rotating sleeve 7 enters the tank. The support assembly outputs power to drive the annular joint 9 to move linearly, so that the multiple first connecting rods 10 on the annular joint 9 rotate. At the same time, the second connecting rod 12 rotates in coordination with the first connecting rod 10, driving the positioning support plate 11 towards one end of the inner wall of the tank until it is in complete contact with the tank. At the same time, the pressure sensor 13 detects the pressure applied to the tank by the positioning support plate 11 to avoid uneven force or excessive pressure, and transmits the control signal to the support assembly in time for timely adjustment. Then, the drive assembly outputs power to the driven turntable 6, so that the driven turntable 6 rotates, driving the rotating sleeve 7 to rotate together, realizing the rotation of the tank for multi-angle welding. The pressure sensor 13 in this device is model CYYZ11.

[0024] Please see Figures 1-5In this embodiment, the height adjustment assembly includes a first motor 301 and threaded rods 302. The first motor 301 is fixedly connected to the side plate 2, and two threaded rods 302 are fixedly connected to the output end of the first motor 301. The first motor 301 drives the threaded rods 302 to rotate. The threaded rods 302 are rotatably connected to the side plate 2, and the threaded rods 302 and slider 4 are threadedly connected. The first motor 301 outputs power to the threaded rods 302, causing them to rotate and drive the slider 4, which is threadedly connected to the threaded rods 302, to move linearly. Simultaneously, the two threaded rods 302 limit the movement of the slider 4. The driving assembly includes a second motor 501, a first rotating shaft 502, an active turntable 503, and a belt 504. The second motor 501 is fixedly connected to the side plate 2, and the first rotating shaft 502 is fixedly connected to the output end of the second motor 501.

The other end of the belt 504 is sleeved on the driven turntable 6. The second motor 501 outputs power to the first rotating shaft 502, causing the first rotating shaft 502 to rotate. The first rotating shaft 502 drives the drive turntable 503 to rotate, causing the outer belt 504 to rotate, thereby driving the driven turntable 6 to rotate. The supporting assembly includes a first hydraulic cylinder 801 and a first hydraulic rod 802. The first hydraulic cylinder 801 is fixedly connected inside the rotating sleeve 7. The output end of the first hydraulic cylinder 801 is fixedly connected to the first hydraulic rod 802. The first hydraulic cylinder 801 is used to push the first hydraulic rod 802 to perform linear motion. The other end of the first hydraulic rod 802 is fixedly connected to the annular joint 9. The first hydraulic cylinder 801 outputs pressure to the first hydraulic rod 802, pushing the first hydraulic rod 802 to perform linear motion, thereby driving the annular joint 9 to perform linear motion.

[0025] Please see Figures 1-2In this embodiment, a fixed support 14 is fixedly connected to the base plate 1, and a width adjustment component is slidably connected to the fixed support 14. Two third connecting rods 16 are rotatably connected to both ends of the width adjustment component, and a sliding support 17 is rotatably connected to the other end of each third connecting rod 16. Power is output from the width adjustment component to the third connecting rods 16 at both ends, causing them to rotate and thus drive the sliding support 17 to slide, adjusting the width of the tank. Simultaneously, the fixed support 14 limits the movement of the width adjustment component. The width adjustment component includes a second hydraulic cylinder 1501, a second hydraulic rod 1502, and a connecting block 1503. The second hydraulic cylinder 1501 is slidably connected to the fixed support 14, and the output end of the second hydraulic cylinder 1501 is fixedly connected to the second hydraulic rod 1502. The second hydraulic cylinder 1501 is used to push the second hydraulic rod 1502 in a linear motion. The second hydraulic cylinder 1501 and the second hydraulic rod 1502... One end is fixedly connected to a connecting block 1503, which is rotatably connected to two third connecting rods 16. The second hydraulic cylinder 1501 outputs pressure to the second hydraulic rod 1502, pushing the second hydraulic rod 1502 to move linearly. At the same time, the output force acts on the second hydraulic cylinder 1501, causing the second hydraulic cylinder 1501 to move linearly in the opposite direction. This enables the two connecting blocks 1503 at both ends to move linearly together, driving the third connecting rods 16 to rotate. The bottom plate 1 has two first sliding grooves 101 on both sides. The first sliding grooves 101 are slidably connected to the sliding support 17. The sliding support 17 is fixedly connected to a second rotating shaft 18. The outer side of the second rotating shaft 18 is rotatably connected to a roller 19. The tank to be welded is placed on the roller 19. The roller 19 is rotatably connected to the second rotating shaft 18, which will not cause motion interference when the tank rotates. At the same time, the sliding support 17 slides on the first sliding groove 101 to adapt to tanks of different sizes.

[0026] During operation, the tank to be welded is placed on roller 19, which is rotatably connected to the second rotating shaft 18, preventing motion interference during tank rotation. Then, based on the tank dimensions, the second hydraulic cylinder 1501 outputs pressure to the second hydraulic rod 1502, pushing it to move linearly. Simultaneously, the output force reacts on the second hydraulic cylinder 1501, causing it to move linearly in the opposite direction. This results in the two connecting blocks 1503 moving linearly together, driving the third connecting rod 16 to rotate, which in turn causes the sliding support 17 to slide, adjusting the width of the tank. Then, the first motor 301 outputs power to the threaded rod 302, causing it to rotate and driving the slider 4 threaded onto the threaded rod 302 to move linearly to a suitable height. Finally, the rotating sleeve 7 enters the tank, and the first hydraulic cylinder... The pressure output by 801 is given to the first hydraulic rod 802, which pushes the first hydraulic rod 802 to move linearly, thereby driving the annular joint 9 to move linearly. This causes the multiple first connecting rods 10 on the annular joint 9 to rotate. At the same time, the second connecting rod 12 rotates in coordination with the first connecting rod 10, driving the positioning support plate 11 towards one end of the inner wall of the tank until it is in complete contact with the tank. Meanwhile, the pressure sensor 13 detects the pressure applied to the tank by the positioning support plate 11 to avoid uneven force or excessive pressure, and transmits the control signal to the support assembly in time for timely adjustment. Then, the second motor 501 outputs power to the first rotating shaft 502, causing the first rotating shaft 502 to rotate. The first rotating shaft 502 drives the active turntable 503 to rotate, causing the outer belt 504 to rotate, thereby driving the driven turntable 6 to rotate. The driven turntable 6 drives the rotating sleeve 7 to rotate together, realizing the rotation of the tank and performing multi-angle welding.

[0027] Through the above steps, by using multiple component drives and multiple connecting parts transmission, the positioning support plate 11 can adapt to tanks of various sizes. The pressure sensor 13 is used for real-time detection, which facilitates flexible adjustment and ensures that the weld position is at the optimal welding angle. This effectively reduces defects such as incomplete penetration and porosity, improves the aesthetics and pass rate of the weld, reduces material waste caused by welding errors, and improves welding quality and precision. This solves the problem that traditional tank welding positioning devices cannot adapt to various tank sizes, cannot be flexibly adjusted, and thus lead to decreased docking accuracy, reduced weld quality, and increased structural deformation and internal stress.
