[0003] After retrieval, a patent with the Chinese patent application number 202221909110.6 discloses a ship sectional rapid welding device, which includes a welding machine and a base detachably connected to the bottom end of the welding machine. A bracket is provided on one side of the base away from the welding machine, and brake rollers are installed at the four corners of the bottom end of the bracket; both sides of the bracket are fixed with supports, and two hydraulic cylinders are fixed to the bottom ends of the two supports. The piston rods of the two hydraulic cylinders on one side of the bracket are connected to a support plate provided on one side of the bracket, and the piston rods of the other two hydraulic cylinders are connected to a support plate provided on the other side of the bracket. A plurality of suction cups are fixed to the bottom ends of the two support plates; a box body is provided on one side of the base, and a handrail is fixed to the side wall of the bracket; two insertion blocks are fixed to the bottom end of the base, two baffles are fixed inside the bracket, the bottom ends of the two insertion blocks penetrate through the bracket, and through holes for guide rods to pass through are opened in the two baffles; springs I are sleeved on the two guide rods, limit blocks are fixed to the opposite ends of the two guide rods, and slots adapted to the limit blocks are opened on the opposite side walls of the two insertion blocks.

[0004] The ship sectional rapid welding device in the above patent has the following deficiencies: By setting hydraulic cylinders, support plates and suction cups, the piston rods of the hydraulic cylinders drive the support plates and suction cups to move downwards, and the suction cups are adsorbed on the ship, improving the overall stability and welding efficiency; however, in the actual welding process, the multi-section hulls of the ship are fixed on the shipbuilding berth through fixing devices and do not shake by themselves. For the hulls that need to be welded section by section, their volumes are very large and the welding seams are very long. For the fixed-form welding device, the welding wires between the welding torch and the welding box will be very long, which is not conducive to the use of the overall device.
