Background

When prefabricating and welding barrel products, a welding roller carrier is needed to rotate the barrel so as to facilitate assembly and welding. The traditional welding roller frame is divided into five types, namely a basic type, an exchange type, a self-adjusting type, an adjustable center height type and a deflectable axis type, the basic type and the adjustable roller frame are the most common, and the equipment is widely applied to the construction and production of barrel products.

However, when a conical cylinder and a reducing cylinder are encountered in production, the central axis of the cylinder is deviated due to the fact that the cylinder contacts with the roller and inclines to a section with a small diameter, axial movement gradually occurs due to unequal diameters of the cylinder contacting with the roller when the cylinder rotates, and for example, the conical cylinder and the reducing cylinder with phi 1500 mm/phi 1000mm L =6000mm, two roller frames are located at the positions 3m away from the center of the cylinder. On average one revolution, axial play of around 170mm and 185mm occurs on conventional rollers. The axial movement can cause the change of the alignment precision and the size during the automatic welding of the submerged arc welding, and particularly, the automatic welding of the submerged arc welding needs an operator to continuously adjust the position of a welding gun, thereby causing great construction obstacles for construction and production. At the moment, the phenomenon of clamping the cylinder can occur when the angle of a connecting line between the two rollers and the diameter center of the small-opening cylinder is too large, the cylinder can be clamped flatly, and quality accidents are caused.
