Detailed Implementation

[0030] The attached figure shows a specific embodiment of this utility model. This embodiment includes a left frame 1 and a right frame 2. A pair of lower rollers 3 are provided on the left frame 1 and the right frame 2, and an upper roller 4 is provided above the lower rollers 3. The left frame 1 and the right frame 2 are connected as a whole by a connecting beam 5. The two ends of the lower rollers 3 are respectively installed on the lower roller seats 6, which are installed on the guide rail plate 7. The lower roller seats 6 are connected to the translation cylinder 8. The right end of the upper roller 4 is equipped with a four-wheel drive merging main transmission system. The right side of the right frame 2 is equipped with a balance cylinder 9, which is connected to one end of the balance frame body 10. A support frame 11 is installed on the right frame 2, and a chain 12 is installed on the support frame 11. A cantilever beam 13 is fixed to the side of the chain 12. An error correction frame 14 is installed between the left frame 1 and the right frame 2. Several error correction wheels 15 that contact the plate are installed on the error correction frame 14. Feeding centering roller conveyors 16 are provided on both sides of the left frame 1 and the right frame 2.

[0031] The feeding centering roller conveyor 16 is installed on the feeding frame 18. Several sets of symmetrical centering cylinders 19 are provided on both sides of the feeding frame 18. The feeding centering roller conveyor 16 is driven by the feeding motor 20. The error correction frame 14 is hinged between the left frame 1 and the right frame 2. The lower part of the error correction frame 14 is hinged to the output end of the error correction cylinder 21. The error correction frame 14 consists of a fixed error correction frame 22 and a movable error correction frame 23. The movable error correction frame 23 can slide along the fixed error correction frame 22. A width adjustment cylinder 24 is connected between the movable error correction frame 23 and the fixed error correction frame 22.

[0032] The chain 12 is wound around the lifting cylinder 25. Rollers 26, which are locked to both sides of the support frame 11, are installed on the upper and lower sides of the cantilever beam 13. A support wheel frame 27 is installed at the end of the cantilever beam 13, and several support wheels 28 are installed on the support wheel frame 27.

[0033] The four-wheel drive confluence main transmission system includes a large gear 29 that drives the upper roller 4 to rotate. The large gear 29 meshes with four small gears 30. Each small gear 30 is driven by a planetary reducer 31, and each planetary reducer 31 is driven by a hydraulic motor 32.

[0034] The output end of the balancing cylinder 9 is connected to the push rod 33. The bottom of the push rod 33 is provided with a ball cup 34, which is fixed in the inner cavity of the balancing frame 10. The balancing frame 10 is hinged to one end of the balancing rod 35, and the other end of the balancing rod 35 is hinged to the right frame 2.

[0035] One end of the upper roller 4 is installed in the inner hole of the reversing frame 36, and the other end is installed between the two right frames 2. The reversing frame 36 is hinged to the left frame 1. The side of the reversing frame 36 is hinged to the output end of the reversing frame cylinder 37. The bottom end of the reversing frame cylinder 37 is hinged to the left frame 1. The bottom of the reversing frame 36 is connected to the first main cylinder 38. The reversing frame 36 can move up and down along the left frame 1. The right end of the upper roller 4 is connected to the second main cylinder 39.

[0036] The deep-sea wind turbine tower rolling machine of this invention places the sheet metal on the feeding centering roller conveyor 16 of the feeding rack 18. The feeding motor 20 drives the feeding centering roller conveyor 16 to rotate, transporting the sheet metal forward. During transport, if the sheet metal deviates from its original position, the centering cylinder 19 on the side of the deviation is activated to push the sheet metal to the center position. When the sheet metal enters between the upper roller 4 and the lower roller 3, the four-drive confluence main transmission system is activated. The hydraulic motors 32 rotate under the drive of the hydraulic system. Each of the four hydraulic motors 32 drives the planetary reducer 31 to output different speeds. The planetary reducer 31 drives the pinion 30 to rotate, the pinion 30 drives the large gear 29 to rotate, and finally the large gear 29 outputs power to drive the upper roller 4 to rotate, realizing the rolling action. By confluence of multiple small hydraulic motors 32, a large torque output can be achieved, thus completing the one-time forming rolling process.

[0037] After the rolling begins, the lifting cylinder 25 rises, driving the cantilever beam 13 to move upward along the support frame 11 via the chain 12 until the cantilever beam 13 moves upward to the point where the support wheel 28 contacts the inner wall of the sheet material, thus supporting the rolled sheet material. This makes the rolling of large-diameter and heavy sheets safer and more stable. Rollers 26 are installed on both sides of the support frame 11 to ensure the stability of the cantilever beam 13 as it moves up and down.

[0038] During the rolling process, the correction cylinder 21 is activated to drive the correction frame 14 to rotate until the correction wheel 15 contacts the surface of the sheet material, providing some support to the rolled sheet material from the side. When the workpiece is rolled and joined, the correction cylinder 21 can correct the misalignment, and then welding can be performed. The correction frame 14 consists of a fixed correction frame 22 and a movable correction frame 23. Under the action of the width adjustment cylinder 24, the movable correction frame 23 can slide along the fixed correction frame 22, thereby adjusting the width of the correction frame 14 to adapt to the rolling of sheet materials of different widths.

[0039] After the paper roll is completed, the tilting frame cylinder 37 drives the tilting frame 36 to flip outward, thus pulling out the rolled board. At the same time, the balance cylinder 9 drives the push rod 33 to press against the transmission box of the four-wheel drive confluence main transmission system, causing the upper roller 4 to tilt up and cooperate with the tilting frame 36 to flip over. The push rod 33 presses against the ball cup 34 to transmit force to the inner end of the balance frame 10. Meanwhile, the balance frame 10 is hinged and supported by the balance bar 35, ensuring the stability of the balance frame 10.

[0040] When rolling plates of different thicknesses and diameters, the translation cylinder 8 is activated, which drives the lower roller seat 6 to move along the guide rail plate 7, thereby adjusting the distance between the two lower rollers 3, thus making it suitable for rolling plates of different thicknesses and diameters.
