Description

Technical Field

[0001] The invention relates to the technical field of steel pipe welding supports, in particular to a movable support for a welding roller frame. Background Art

[0002] The welding roller frame is a welding auxiliary equipment, which is commonly used for welding inner and outer circumferential seams and inner and outer longitudinal seams of cylindrical workpieces. The existing roller frame is placed directly on the ground. When the length of the steel pipe changes, the position of the roller frame needs to be adjusted by a crane. During adjustment, the two roller frames are not easy to align with the center. The steel pipe will change during welding, and the workpiece will collide with the roller, causing the workpiece to fall. During adjustment, the steel pipe needs to be lifted by a crane and then adjusted by a crowbar, which is time-consuming and prone to the problem of the roller frame tipping over. At the same time, the welding roller frame is not convenient for limiting steel pipes of different specifications. After welding on one side of the steel pipe is completed, it is not convenient to flip the steel pipe, and manual flipping is required to perform welding operations on other positions of the steel pipe. At the same time, the height of the welding roller frame is not convenient to adjust according to actual needs, and cannot meet the convenience of welding work for staff who are not tall enough.
