[0030] Refer to Figure 1-2 , a tank body turnover welding rack, which is applied to the welding of the tank body, facilitates the adjustment of the position of the tank body, and improves the welding efficiency.

[0031] The tank body turnover welding rack mainly includes a bottom plate 1 and a plurality of turnover mechanisms. Each turnover mechanism is arranged at intervals on the upper surface of the bottom plate 1 and is located on the same straight line. Each turnover mechanism includes a sliding seat 2, two brackets, a driving wheel 12, a first motor 14 and a second motor 10;

[0032] The driving wheel 12 is rotatably arranged above the sliding seat 2 and between the two brackets;

[0033] The first motor 14 is connected to the driving wheel 12 to drive the driving wheel 12 to rotate;

[0034] The second motor 10 is connected to the two threaded rods 9 to drive the two threaded rods 9 to rotate, thereby driving the two brackets to move, so that the two supporting wheels 5 move inwards or outwards;

[0035] A slide rail 15 is provided at the top of the bottom plate 1, and the sliding seat 2 is slidably connected to the bottom plate 1 through the slide rail 15, so that the sliding seat 2 can be translated above the bottom plate 1, thereby adjusting the distance between the multiple brackets to stably support the tank body 6 for different sizes or welding positions of the tank body 6, facilitating welding. Moreover, fixing holes 17 are provided at the tops of both the bottom plate 1 and the sliding seat 2. A pin 18 is provided inside one fixing hole 17. After the position of the sliding seat 2 is determined, the pin 18 is passed through the sliding seat 2 and inserted into the fixing hole 17 of the bottom plate 1, so that the sliding seat 2 can be fixed above the bottom plate 1, thereby facilitating the brackets to support and fix the tank body 6;

[0036] The two brackets are respectively arranged at both ends of the sliding seat 2. Each bracket includes a connecting rod 3, a support rod 4 and a threaded rod 9. A support wheel 5 is provided at the upper end of the support rod 4, and the lower end is rotatably connected to the sliding seat 2. The two support wheels 5 are located on the left and right sides obliquely below the tank body 6 to support the tank body 6. The threaded rod 9 is horizontally arranged on the sliding seat 2. The upper end of the connecting rod 3 is rotatably connected to the support rod 4. A moving block 8 is rotatably connected to the lower end of the connecting rod 3. A threaded through hole is provided on one side of the moving block 8. The moving block 8 is threadedly connected to the threaded rod 9 through the threaded through hole. One end of the threaded rod 9 passes through the lower end of the support rod 4. Fixed blocks 7 are provided on both sides of the top end of the bottom plate 1. The axes of the two threaded rods 9 are on the same straight line, and the two threaded rods 9 are fixedly connected between them. The two threaded rods 9 are rotatably connected between the two fixed blocks 7, and the thread directions of the two threaded rods 9 are opposite. The second motor 10 is arranged above the bottom plate 1. Gears are provided on the output shaft of the second motor 10 and the outside of the threaded rod 9. The two gears are meshed. The second motor 10 is a servo drive motor. Through the gears, the second motor 10 can drive the two threaded rods 9 to rotate. When the two threaded rods 9 with opposite thread directions rotate, they drive the two moving blocks 8 to approach or move away from each other, so that the lower ends of the two connecting rods 3 approach or move away from each other, so that the upper ends of the two connecting rods 3 respectively drive the lower ends of the two support rods 4 to rotate, so that the two support wheels 5 approach or move away from each other, thus facilitating the support and fixation of the tank body 6 of different sizes;

[0037] Two support plates 11 are fixedly connected to the top of the bottom plate 1. There are two driving wheels 12, and both driving wheels 12 are rotatably connected between the two support plates 11. The tank body 6 is located above the two driving wheels 12 to support the tank body 6. A second pulley is provided on one side of the two driving wheels 12, and a second belt 16 is provided outside the two second pulleys. The two driving wheels 12 can be driven to rotate synchronously through the second belt 16. The first motor 14 is arranged above the sliding seat 2. A first pulley is provided on the output shaft of the first motor 14 and on one side of one of the driving wheels 12, and a first belt 13 is provided outside the two first pulleys. The first motor 14 is a servo drive motor. The first motor 14 drives one of the driving wheels 12 to rotate through the first belt 13, and then drives the two driving wheels 12 to rotate synchronously through the second belt 16, so as to drive the tank body 6 above the two driving wheels 12 to rotate and adjust the position, facilitating the rotation of the welding part above the tank body 6 to the bottom, so as to facilitate the welder to carry out welding. Rubber sleeves are provided outside both the supporting wheels 5 and the driving wheels 12. The rubber sleeves can increase the friction between the driving wheels 12 and the tank body 6, facilitating the driving wheels 12 to drive the tank body 6 to rotate for position adjustment. At the same time, it can prevent the contact parts of the tank body 6 with the supporting wheels 5 and the driving wheels 12 from being deformed due to pressure.

[0038] The working principle of this tank body turnover welding rack: First, slide the sliding seat 2 above the bottom plate 1 to determine the distance between each turnover mechanism for supporting and fixing the tank body of different sizes at multiple positions. After the position of the sliding seat 2 is determined, insert the pin 18 so that the pin 18 passes through the sliding seat 2 and inserts into the fixing hole 17 of the bottom plate 1, thus fixing the sliding seat 2 above the bottom plate 1. Subsequently, place the tank body 6 to be welded on the turnover mechanism through other transportation equipment (such as a lifting device). At this time, the tank body 6 is located above the two driving wheels 12. Then, drive the threaded rod 9 to rotate through the second motor 10. When the two threaded rods 9 with opposite thread directions rotate, drive the two moving blocks 8 to approach each other, so that the lower ends of the two connecting rods 3 approach each other, causing the lower ends of the two support rods 4 to be driven to rotate by the upper ends of the two connecting rods 3 respectively, so that the two supporting wheels 5 approach each other to support the lower left and right sides of the tank body 6 of different sizes obliquely below. At this time, the tank body 6 is supported and fixed by the two supporting wheels 5 and the two driving wheels 12. When the welding position of the tank body 6 needs to be adjusted, the first motor 14 drives one of the driving wheels 12 to rotate through the first belt 13, and the second belt 16 drives the two driving wheels 12 to rotate synchronously, so as to drive the tank body 6 above the two driving wheels 12 to rotate, making the welding part above the tank body 6 rotate and move to the bottom, so as to facilitate the welder to carry out welding.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
