Description

Technical Field

[0002] In the construction of offshore engineering jackets, the cone (conical component) is a key connecting part, and the quality of its longitudinal seam welding directly affects the structural strength. Traditional welding processes have the following problems:

The lifting and adjusting assembly 4 and the drive wheel units 20 are both controlled by the electrical control system.

[0026] By using the roller frame of this application, the distance between the two driving roller units 20 can be adjusted by the first adjusting unit 21, and the distance between the two driven roller units 30 can be adjusted by the second adjusting unit 31. This allows for quick adaptation of the external conical profile of the conical component. Furthermore, by adjusting the height of the two driven roller units 30 by the lifting adjusting component 4, the surface of the conical component placed on the roller frame can be quickly leveled. This method offers high leveling efficiency, high precision, and good stability, and can meet the welding requirements of the conical component.
