Description

Technical Field

[0001] The utility model relates to the technical field of welding aids, and more particularly to a hanging bracket for ship welding. Background Art

[0002] During the processing of a ship hull, it is necessary to weld some equipment and structures on the ship hull. However, since the volume and weight of ship welding workpieces are usually large, during the welding process, a hanging bracket and a supporting device are required to limit and support the welding main body and the workpiece to be welded.

[0003] For example, a welding hanging bracket structure with the patent publication number CN220679803U includes a hanging bracket. One side of the hanging bracket is fixedly connected with a driving motor. The output shaft of the driving motor is fixedly connected with an installation lead screw through a coupling. The surface of the installation lead screw is threadedly sleeved with an adjusting nut sleeve. One side of the adjusting nut sleeve is fixedly connected with an electric push rod. A connecting component is arranged at the bottom end of the electric push rod. One end of the connecting component is fixedly connected with an upper pressing plate, and a lower pressing plate is arranged at the bottom of the upper pressing plate. The utility model can drive the electric push rod, the upper pressing plate, the lower pressing plate and the clamped workpiece to move in position, and is more convenient for welding the clamped workpiece on the welding hanging bracket.

[0004] In the welding hanging bracket structure proposed in the above patent document, during the actual limiting process of the workpiece by the upper pressing plate and the lower pressing plate of the limiting mechanism, the welding workpiece main body cannot be stably supported and limited, and the workpiece is prone to unstable positioning. Moreover, the arc-shaped structure cannot be applied to limit workpieces with different diameters, resulting in a small application range of the limiting mechanism. Therefore, it is necessary to improve the limiting mechanism. Summary of the Utility Model
