Abstract

The invention relates to a longitudinal and circumferential seam welding device for a large pressure container barrel, and belongs to the technical field of welding. The stability of a cantilever is improved, the starting resistance of a lifting platform is reduced, and fine adjustment of a welding gun is facilitated, so that the welding positioning is accurate. An automatic wire feeding welding machine comprises a wire feeding mechanism and a welding gun fixing mechanism; a sliding lifting platform comprises a sliding platform, a cantilever support frame, the lifting platform and a transversedriving mechanism, wherein the sliding platform is fixedly connected to the cantilever support frame, one side of the cantilever support frame is connected to the lifting platform, the transverse driving mechanism is fixed on the lifting platform, and the transverse driving mechanism is fixedly connected to the welding gun fixing mechanism; a roller frame is fixed below the lifting platform; anda first guide mechanism is arranged between the cantilever support frame and the lifting platform, the first guide mechanism comprises guide rods and guide wheels, the guide wheels are fixed on the two sides of the lifting platform, and the guide rods matching the guide wheels are fixed on the cantilever support frame.

Description

technical field [0001] The invention relates to a longitudinal and circumferential seam welding device for a cylinder body of a large pressure vessel, belonging to the technical field of welding. Background technique [0002] When welding the longitudinal and circumferential seams of the current relatively large pressure vessel cylinder, due to the large volume of the cylinder, the movement and handling remain unchanged, and it is generally impossible to use the leaping welding platform to weld the cylinder. , often encounter problems such as cantilever instability, large lifting resistance, inaccurate positioning, and inability to fill the weld seam, which can easily lead to welding failure. Contents of the invention [0003] The object of the present invention is to propose a welding device for the longitudinal and circumferential seams of large pressure vessel cylinders, which can improve the stability of the cantilever, reduce the lifting resistance of the lifting plat...
