Its shape is similar to a cylinder, but it emphasizes its function as a shell. In the fields of engineering and manufacturing, cylindrical shells are often used to make containers, pipes, columns and other structures.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when welding the cylindrical steel shell, usually the two cylindrical steel shells are just fixed together and then welded. This makes it difficult for the workers to rotate the cylindrical steel shell during welding, which affects the workers' welding of the cylindrical steel shell.

[0007] The effect achieved by the mutual balancing of the above components is that the angle of the cylindrical steel shell can be adjusted when the cylindrical steel shell is welded, thereby making it convenient for workers to weld the cylindrical steel shell.

[0008] Preferably, an adjustment plate is fixedly installed at one end of the two limit rods that are away from each other, and a plurality of positioning holes are evenly opened on the surface of the adjustment plate.

A connecting plate is fixedly installed at one end of the two push rods that are close to each other.

[0009] The effect achieved by the above components is that after the push rod is inserted into the positioning hole of the adjustment plate, the adjustment plate cannot rotate, and the cylindrical shell cannot rotate either, thereby achieving the effect of limiting the rotation of the cylindrical shell.

[0010] Preferably, the arc surfaces of the two push rods are both sleeved with springs, and the two ends of the springs are respectively fixedly connected to the support frame and the connecting plate.

[0018] In summary:

[0019] In the utility model, when it is necessary to weld the cylindrical steel shell, first rotate the rotating block, and the rotating block moves upward with the help of the thread. The rotating block drives the lifting cylinder to move while the rotating block moves, and the lifting cylinder drives the mounting frame to move while the mounting frame moves. After the mounting frame moves to the required height, adjust and rotate the rotating block, and then place the cylindrical shell on the mounting frame, and then slide the top plate. After the top plate slides a certain distance in the direction close to the cylindrical shell, rotate the push cylinder, and the push cylinder moves in the direction of the limit rod. The push cylinder drives the top plate to move while the push cylinder moves. After the top plate moves a certain distance, the surface of the top plate squeezes the cylindrical shell. At this time, the two cylindrical shells are fixed together. At this time, the cylindrical shell can be welded. When it is necessary to weld the lower part of the cylindrical shell, slide the connecting plate in the direction close to the cylindrical shell. The connecting plate slides while the top rod slides. After the top rod slides a certain distance, the top rod slides out of the adjustment When the adjusting plate rotates, the limiting rod is driven to rotate, and the limiting rod is driven to rotate, and the threaded rod is driven to rotate, and the top plate is driven to rotate, and the cylindrical shell is driven to rotate. After the cylindrical shell rotates to the required angle, the cylindrical rotating frame is released, and then the connecting plate is released. The connecting plate moves away from the threaded rod under the action of the spring tension, and the connecting plate drives the top rod to move. After the top rod moves a certain distance, the top rod is inserted into the inner wall of the positioning hole corresponding to the adjusting plate. At this time, the adjusting plate cannot rotate, and the cylindrical shell cannot rotate. At this time, the cylindrical shell can continue to be welded. The effect achieved by the mutual balance of the above components is that the angle of the cylindrical steel shell can be adjusted when welding the cylindrical steel shell, so as to facilitate the staff to weld the cylindrical steel shell.

The ends of the two limit rods 3 that are far from each other are fixedly installed with an adjustment plate 10. The surface of the adjustment plate 10 is evenly provided with a number of positioning holes 12. The insides of the two support frames 2 are slidably inserted with a push rod 13. The size of the push rod 13 matches the size of the positioning hole 12. The ends of the two push rods 13 that are close to each other are fixedly installed with a connecting plate 15. After the push rod 13 is inserted into the positioning hole 12 of the adjustment plate 10, the adjustment plate 10 cannot rotate, and the cylindrical shell 4 cannot rotate either, thereby achieving the effect of limiting the rotation of the cylindrical shell 4. The arc surfaces of the two push rods 13 are both covered with springs 14. The two ends of the spring 14 are respectively fixedly connected to the support frame 2 and the connecting plate 15. The spring 14 can drive the connecting plate 15 to slide under its own tension, thereby achieving the effect of assisting the sliding of the connecting plate 15. Two rotating frames 11 are fixedly installed on the surfaces of the two adjustment plates 10. The cross section of the rotating frame 11 is "L" shaped. When the rotating frame 11 is rotated, the adjusting plate 10 is driven to rotate while the rotating frame 11 rotates, thereby achieving the effect of driving the adjusting plate 10 to rotate. Anti-deviation frames 9 are fixedly mounted on the surfaces of the two threaded rods 8. The surfaces of the anti-deviation frames 9 are slidably connected to the top plate 7. The top plate 7 can slide with the assistance of the anti-deviation frames 9, so that the top plate 7 will not deviate when sliding up and down. Two baffles 5 are rotatably connected to the surface of the bracket 1. Two bottom rods 21 are fixedly inserted inside the baffles 5. Four limit pads 20 are fixedly mounted on the surface of the bracket 1. The limit pads 20 are elastic pads. The baffles 5 can block the debris generated during the welding process so that the debris will not fall on the ground.

[0026] Working principle: when it is necessary to weld the cylindrical steel shell, first rotate the rotating block 18, and the rotating block 18 moves upward with the help of the thread. When the rotating block 18 moves, it drives the lifting cylinder 17 to move, and when the lifting cylinder 17 moves, it drives the mounting frame 16 to move. After the mounting frame 16 moves to the required height, adjust and rotate the rotating block 18, and then place the cylindrical shell 4 on the mounting frame 16, and then slide the top plate 7. After the top plate 7 slides a certain distance in the direction close to the cylindrical shell 4, rotate the push cylinder 6, and the push cylinder 6 moves in the direction of the limit rod 3. When the push cylinder 6 moves, it drives the top plate 7 to move. After the top plate 7 moves a certain distance, the surface of the top plate 7 squeezes the cylindrical shell 4. At this time, the two cylindrical shells 4 are fixed together. At this time, the cylindrical shell 4 can be welded. When it is necessary to weld the bottom of the cylindrical shell 4, slide the connecting plate 15 in the direction close to the cylindrical shell 4. When the connecting plate 15 slides, it drives the top rod 13 to slide. After the top rod 13 slides a certain distance, the top rod 13 slides out of the adjustment plate When the cylindrical shell 4 is rotated to the required angle, the cylindrical rotating frame 11 is rotated, and then the connecting plate 15 is loosened, and the connecting plate 15 moves in the direction away from the threaded rod 8 under the pulling force of the spring 14. When the connecting plate 15 moves, the top rod 13 is driven to move. After the top rod 13 moves a certain distance, the top rod 13 is inserted into the inner wall of the positioning hole 12 corresponding to the adjusting plate 10. At this time, the adjusting plate 10 cannot be rotated, and the cylindrical shell 4 cannot be rotated. At this time, the cylindrical shell 4 can continue to be welded. The effect achieved by the mutual balance of the above components is: the angle of the cylindrical steel shell can be adjusted when welding the cylindrical steel shell, so as to facilitate the staff to weld the cylindrical steel shell.
