Abstract

The invention provides a straight seam welding and grouping welding method for a large-diameter cylinder, and relates to the technical field of welding equipment. The straight seam welding and grouping welding method for the large-diameter cylinder comprises the following steps that firstly, rolling wheels on a driving welding walking rolling wheel frame, a driven welding walking rolling wheel frame and at least two hydraulic jacking grouping rolling wheel frames are placed on two parallel rails which are arranged on the ground in advance, wherein the hydraulic jacking grouping rolling wheel frames are located between the driving welding walking rolling wheel frame and the driven welding walking rolling wheel frame; and the driving welding walking rolling wheel frame is placed close to the end, needing to be welded, of the cylinder. A hydraulic supporting arm mechanism is adjusted, the cylinder can be jacked from the two side faces of the cylinder, the hydraulic supporting arm mechanism is used for correcting and lifting a workpiece with the large cylinder diameter to prevent the workpiece with the large cylinder diameter from collapsing, the roundness of the workpiece with the large cylinder diameter is corrected, more time and labor can be saved when the workpiece with a large cylinder diameter is welded and assembled, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to the straight seam welding and team welding method of large-diameter cylinders. Background technique [0002] In the prior art, there is equipment for team welding of large-diameter cylinders for offshore wind power. The equipment can not guarantee the roundness of the workpiece with large cylinder diameter and the phenomenon that the workpiece is lowered in the welding group. The spot welding of the roller frame can only be carried out by the traditional high-frequency adjustment hydraulic group. In this way, it is difficult to ensure the concentricity of the two large cylinder workpieces, and it is impossible to realize automatic assembly and rotary welding. Contents of the invention [0003] The purpose of the present invention is to provide a method for straight seam welding and team welding of large-diameter cylinders, aiming to solve the problems of troublesome...
