Description

Technical Field

[0001] The utility model belongs to the technical field of liftable roller mechanisms, in particular to a liftable roller frame. Background Art

[0002] The existing lifting roller frame usually includes a bottom plate arranged on the bottom surface, a lifting mechanism is arranged on the top of the bottom plate, a top plate is arranged on the top of the lifting mechanism, and a roller frame is arranged on the top of the top plate. When in use, the cylinder to be welded is placed on the roller frame, so that the cylinder can be supported and rolled to facilitate welding of the cylinder. In actual use, when the staff welds the cylinder, since there are rollers on the roller frame, when the staff accidentally touches the cylinder during welding, the rollers can easily drive the cylinder to rotate, so that the staff have to stop in the welding state and wait until the size of the cylinder is readjusted before continuing to weld the cylinder. This will affect the convenience of operation and lead to relatively low welding efficiency, which cannot fully meet people's use needs.

[0003] For example, the utility model with announcement number CN221019386U discloses a lifting and adjustable welding roller frame. In the technical solution of this patent, the staff places the cylindrical material to be processed on the support frame, and then the staff adjusts the height adjustment mechanism according to the welding height to weld the cylinder. However, during the welding process, when the staff accidentally touches the cylinder, the cylinder will rotate under the action of the roller, interrupting the staff's welding of the cylinder. The staff needs to adjust the cylinder again before welding the cylinder, which is time-consuming and labor-intensive, and the welding efficiency is low. Therefore, a lifting and lowering roller frame is proposed. Utility Model Content

The cylinder rotates freely under the action of the roller, saving time and effort, and improving welding efficiency to meet people's usage needs.
