An assembly and welding device for a marine engineering jacket.

Abstract

This utility model discloses an assembly and welding device for a marine engineering jacket, relating to the field of jacket welding. It includes a translational support base with an angle adjustment mechanism. A welding mechanism is located on one side of the angle adjustment mechanism. The welding mechanism includes a lower support frame and an upper support frame. Two semi-gear rings are fixed to the front sides of the lower and upper support frames respectively. A sliding frame is slidably connected to the upper semi-gear ring, and a circumferential motor is fixed to the sliding frame. A circumferential gear meshing with the semi-gear ring is fixed to the output end of the circumferential motor. A second telescopic rod is installed at the front end of the sliding frame, and a welding torch assembly is fixed to the output end of the second telescopic rod. The advantages are: the motion trajectory of the welding torch assembly is a combination of circular motion and axial extension. The electrical components controlling the motion trajectory are only the circumferential motor and the second telescopic rod, which greatly simplifies the control cost and difficulty required for the three-dimensional circular curve of the weld and improves the welding processing speed.
