Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipe processing, in particular to a mobile component used for welded pipe production. Background Art

[0002] During the processing of welded pipes, the steel plates or steel strips are first curled into round or square tubular structures, and then the adjacent welded pipe parts are connected by welding equipment to form a complete steel pipe. Due to the heavy weight of the welded pipe, the labor workload of the workers in the processing and production of the welded pipe will increase. In order to solve the above problem, a moving component for moving the welded pipe is set on the welded pipe processing table.

[0003] After searching, a patent document with patent announcement number CN211277110U discloses a mobile device for welding pipe processing, including a base, a groove is provided on the base, a plurality of support wheels are fixedly provided at the bottom of the groove, a plurality of rolling wheels are provided on the side of the base away from the groove, a rotating shaft is provided at the bottom of the rolling wheel, a first pulley is fixedly provided at the end of the rotating shaft away from the rolling wheel, a plurality of sliding grooves are provided on the base, a sliding member is provided in the sliding groove, a screw hole is provided in the middle of the sliding member, a sliding seat is movably provided at the end of the base away from the sliding groove, a motor is fixedly provided on the sliding seat, a second pulley is provided at the output end of the motor, the first pulley is connected to the second pulley through a belt, and a rotating handle is provided on the end of the lead screw away from the base. A lead screw is provided in the screw hole, and the rolling wheel can be moved by the action of the lead screw to adapt to the size change of the welding pipe.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing mobile device for processing welded pipes, during use, the rolling wheel is driven to rotate by controlling the motor to drive the welded pipe to move inside the groove. However, since the rolling wheels are all arranged on the same side of the groove, there is no rolling wheel limit on the other side of the welded pipe, which will cause the other side of the welded pipe to contact and rub against the inner wall of the groove, which will affect the smooth effect of the welded pipe when moving inside the groove, and even cause the welded pipe to wear, thereby reducing the processing quality of the welded pipe;

[0006] 2. In the existing mobile device for processing welded pipes, during use, the welded pipe is supported by a support wheel arranged inside the groove, which effectively avoids the contact friction between the welded pipe and the inside of the groove, and is conducive to the movement of the welded pipe. However, the height of the support wheel inside the groove is not easy to adjust, which will cause the welded pipe with a smaller diameter to completely enter the groove, and the rolling wheel will be unable to drive the welded pipe. Alternatively, the welded pipe with a larger diameter will protrude more from the groove, causing the welded pipe to detach from the inside of the groove during movement, which will affect the movement effect of the welded pipe, reduce the scope of application of the existing mobile device for processing welded pipes, and reduce practicality.

[0007] To this end, we provide a mobile assembly for welded pipe production to solve the above problems. Utility Model Content
