[0031] Refer to Figure 1-6 , a tank container welding platform, which is applied to the welding of the tank body and the tank cover. In order to facilitate the tight combination of the tank body and the tank cover and improve the welding quality between the tank body and the tank cover.

[0032] The welding platform of the tank container mainly includes a bottom plate 1, a plurality of tank support mechanisms and an end cover support mechanism. Each tank support mechanism is arranged on the bottom plate 1 and located on the same straight line. Each support mechanism includes a first support frame 2, a hydraulic rod 3 and a hub motor 4;

[0033] The first support frame 2 is fixedly arranged on the bottom plate 1. An arc-shaped opening is provided at the top of the first support frame 2 for placing and supporting the tank 5. A placing groove is provided at the bottom of the arc-shaped opening. A rotating seat 15 is rotatably connected to the inner wall of the bottom end of the placing groove. The hydraulic rod 3 is fixedly arranged on the rotating seat 15. A servo drive motor 12 is provided on one side of the first support frame 2. Pulley wheels are provided on the output shaft of the servo drive motor 12 and on the rotating seat 15. A belt 13 is provided outside the two pulley wheels. The servo drive motor 12 can drive the rotating seat 15 to rotate through the belt 13, so that the hydraulic rod 3 rotates. Hub motors 4 are provided on both sides of the upper end of the hydraulic rod 3. The two hub motors 4 are located below the tank 5. Thus, the rotation of the hub motors 4 can drive the tank 5 to rotate (as Figure 5 shown), which is convenient for welding between the tank 5 and the end cover 11. When the hydraulic rod 3 rotates 90°, the hub motors 4 rotate accordingly. At this time, the operation of the hub motors 4 will drive the tank 5 to move horizontally (as Figure 6 shown), so as to facilitate the horizontal movement of the tank 5 close to the end cover 11, making the tank 5 and the end cover 11 fit tightly together, thus facilitating the welding between the tank 5 and the end cover 11. The first support frame 2 is provided with an arc-shaped groove on the inner wall of the arc-shaped opening. A plurality of balls 17 are provided inside the arc-shaped groove. A cage 16 is provided at the arc-shaped opening of the first support frame 2. A plurality of circular through holes are provided on the cage 16. Each ball 17 exposes the cage 16 through a circular through hole. The outer wall of the tank 5 is in contact with each ball 17. The balls 17 can roll, so as to facilitate the rotation or horizontal movement of the tank 5 on the first support frame 2. The cage 16 can fix the positions of the balls 17, so as to facilitate the balls 17 to support the tank 5 and facilitate its movement.

[0034] The end cover support mechanism includes a second support frame 6. The second support frame 6 is fixedly arranged on the bottom plate 1. A circular opening is provided in the middle of the second support frame 6. The axis of the circular opening coincides with the axis of the arc-shaped opening, which can ensure that the end to be welded of the tank 5 and the end to be welded of the end cover 11 are inserted into the circular opening for positioning, alignment and close fitting. A welding joint is provided on one side of the circular opening. At the welding joint, the parts of the tank 5 and the end cover 11 that are positioned, aligned and closely fitted together can be welded. A plurality of fixing components are annularly and equidistantly arranged on one side of the second support frame 6. Each fixing component includes a rotating rod 8, an electric push rod 7 and a fixing wheel 9;

[0035] The rotating rod 8 is rotatably arranged on one side of the second support frame 6. The fixed wheel 9 is arranged at one end of the rotating rod 8. One end of the electric push rod 7 is connected to the second support frame 6, and the other end is rotatably connected to the rotating rod 8. The electric push rod 7 pushes the rotating rod 8 to rotate, so that the fixed wheel 9 rotates accordingly and approaches the end cover 11, thereby supporting the end cover 11 and making the end cover 11 receive force towards the tank body 5 side, so that it is closely attached to the tank body 5, facilitating the welding between the tank body 5 and the end cover 11. Moreover, an annular groove 14 is opened on the inner wall of the circular opening of the second support frame 6. A plurality of cylindrical support wheels 10 are arranged inside the annular groove 14. The cylindrical support wheels 10 can support the connection part between the tank body 5 and the end cover 11, facilitating the positioning connection between the tank body 5 and the end cover 11. At the same time, a rubber sleeve is arranged outside the support wheel 10. When the support wheel 10 supports the connection part between the tank body 5 and the end cover 11, it can prevent the tank body 5 and the end cover 11 from deforming under pressure, improving the welding quality of the tank body 5 and the end cover 11.

[0036] The working principle of this welding platform for the tank container: First, place the tank body 5 at the arc-shaped opening of a plurality of first support frames 2 through a transportation device (such as a lifting device). Subsequently, the hydraulic rod 3 rises, driving the hub motor 4 to contact the bottom of the tank body 5 (as Figure 5 shown). Subsequently, the hub motor 4 rotates, driving the tank body 5 to move horizontally, so that the end of the tank body 5 to be welded enters the circular opening of the second support frame 2. Then, place the end cover 11 at the circular opening of the second support frame 2 through a transportation device (such as a lifting device). Subsequently, each electric push rod 7 pushes the rotating rod 8 to rotate, causing the fixed wheel 9 to move accordingly, contact one side of the end cover 11, and apply force to the end cover 11 towards the inside of the circular opening. At the same time, the hub motor 4 moves the tank body 5 closer to the end cover 11, so that the tank body 5 and the end cover 11 are closely attached. At this time, welding can be carried out between the tank body 5 and the end cover 11 at the welding joint of the second support frame 2. After the connection part between the tank body 5 and the end cover 11 at the welding joint is welded, lower the hydraulic rod 3 to make the hub motor 4 leave the tank body 5. Subsequently, drive the rotating seat 15 to rotate 90° through the servo drive motor 12, so that the hydraulic rod 3 rotates accordingly. Then, raise the hydraulic rod 3 again, and the hub motor 4 contacts the bottom of the tank body 5 (as Figure 4 shown). At this time, when the hub motor 4 rotates, it will drive the tank body 5 to rotate, so that the tank body 5 and the end cover 11 rotate, facilitating the welder to perform all-round welding on the welding part between the tank body 5 and the end cover 11.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
