[0002] During the construction of large cylindrical facilities such as deep-water multifunctional cylindrical protective devices, seabed suction anchors, and land storage tanks, due to the large diameter of the cylinder, it is necessary to splice multiple arc plates. In order to reduce the number of splicing and welding of arc plates on the cylinder and improve the construction efficiency of the facilities, plates with a length of 6 to 12 meters are generally used to roll arc plates. During the rolling process of such arc plates, it is necessary to support the suspended plates on the discharge side. At present, the supporting device configured for the existing three-roller plate rolling machine is mainly composed of a supporting wheel, a support arm, a cylinder, etc. The angle of the support arm is changed by the action of the cylinder, so that the steel plate is supported by the supporting wheel to complete the rolling of the steel plate.

[0003] However, this supporting device is only suitable for the rolling support of small and medium diameter cylinders, and cannot effectively support the suspended plate end on the discharge side of the long-specification arc plate rolling. Therefore, the supporting device configured in the existing plate rolling machine is not suitable for the arc plate rolling support of long-specification plates. When the plate is rolled, due to the effect of the plate's own weight, the suspended plate end on the discharge side often falls and causes bending plastic deformation.

[0004] Therefore, it is urgent to design a plate rolling machine supporting device to solve the problem of long-specification arc plate rolling mentioned above. Utility Model Content

[0046] 3. When the arc plate 9 needs to be rolled multiple times to reach the required curvature, the arc radius of the arc plate 9 will change continuously, and the shaft roller 41 also needs to change the height under the continuous action of the cylinder 23 and always maintain contact with the arc plate 9. At the same time, the support rod 51 also needs to adjust the support angle at any time.

The device increases the support length and the applicable range of the support. The support adjustment is simple and quick. It is suitable for the rolling of arc plates 9 of long specifications of plates with various curvatures 9. It can avoid the bending of the arc plate 9 caused by the falling of the suspended plate end on the discharge side, and effectively ensure the rolling quality of the arc plate 9.
