[0003] Ship steel plate welding is a key process in the shipbuilding process. Steel plates are welded together to form a complete hull. The welding devices in the prior art all use welding workers to use welding guns to weld two steel plates. Because the steel plates have a certain thickness, butt filling is required to complete the welding, which requires multiple welding back and forth, increasing the labor force. Secondly, the worker turns his wrist to adjust the nozzle's spray angle and spray height to adjust the welding method, which is prone to welding deviations and affects the quality of steel plate welding. Finally, because the steel plates have a certain length, welding workers are required to weld for a long time, the working environment is poor, and the workers' eyes are greatly damaged. Sparks are easily splashed on the workers, affecting their health. In addition, because the steel plates are large, they need to be welded in an open area, and the welding points cannot be windproof, affecting the welding process. Summary of the invention

[0004] Based on the technical problems that the existing ship steel plate welding requires welders to weld back and forth multiple times, which increases labor, and secondly, the workers need to turn their wrists to adjust the spray angle and spray height of the nozzle to adjust the welding method, which is prone to welding deviations, affecting the quality of steel plate welding and the health of workers.

[0027] The beneficial effects of the present invention are:

[0028] 1. By setting a moving device, the welding gun device can be driven to move in different ways. The moving device is a device located on the outer surface of the base, which is used to drive the welding device and the windproof device to move on the steel plate to be welded. The moving device includes a moving mechanism and a locking mechanism. The moving mechanism drives the base to move in the horizontal direction by lifting the moving support rod.

A variety of different moving modes can be switched as needed, so that automatic welding can be realized, which solves the technical problem that the existing ship steel plate welding requires multiple welding back and forth, affecting the health of workers.

[0029] 2. By setting a welding device, accurate welding can be automatically performed. The welding mechanism includes a welding gun component. The weld between the two steel plates is welded by starting the welding gun component. The adjusting mechanism includes an adjusting connecting rod. The welding gun component is deflected by moving the adjusting connecting rod. One end of the output shaft of the deflection motor drives the welding gun component to deflect through a gear set to adjust the angle of the welding gun component. The welding gun component is adjusted to various angles by adjusting the connecting rod and the deflection motor. The welding mechanism also includes a connecting shell. The welding gun component is hinged to the outer side of the connecting shell through a pin shaft. A wire roller component with welding wire is fixedly installed on the upper surface of the connecting shell. The welding wire on the wire roller is automatically pumped through the welding wire feeding system. Through the above design scheme, the position and angle of the welding gun component during the welding process can be accurately positioned and adjusted, thereby ensuring welding quality and efficiency, and solving the existing ship steel plate welding. The welding method requires welders to rotate their wrists to adjust the spray angle and spray height of the nozzle, which is prone to welding deviations and affects the quality of steel plate welding. Technical problems.

[0030] 3. By setting up a windproof device, windproof work can be performed during the welding process. The lifting of the windshield can protect the welding gun components from wind during welding. One end of the piston rod of the lifting hydraulic cylinder penetrates the lower surface of the lifting plate and is hinged to the outer side of the windshield through a spherical hinge. The windshield is fixedly installed on the lower surface of the lifting plate. The lifting of the lifting hydraulic cylinder can drive the windshield to be lifted and lowered. After the windshield and the lifting hydraulic cylinder are hinged through a spherical hinge, the windshield can be adjusted accordingly with the unevenness of the steel plate, thereby effectively preventing the wind from interfering with the welding process. This solves the technical problem that the existing ship steel plate welding cannot protect the welding point from wind, affecting the welding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Working principle: when it is necessary to weld the steel plates, after the positions of the two steel plates are fixed, the driving motor 27 on the base 1 is started to drive the two rotating shafts 24 to rotate, and the rotation of the rotating shaft 24 drives the push handle 25 to rotate.

The steering motor 31 is started, and after the fixed frame 3 is deflected through the gear set, it can be directly turned to facilitate the movement of the base 1.

[0057] When welding is required, the double-headed screw 61 on the support frame 6 is rotated under the start of the adjustment motor 62, driving the two adjustment sliders 63 to move relative or oppositely, and then the push frame 64 on the adjustment slider 63 moves relative or oppositely, driving the two adjustment connecting rods 65 to push the connecting shell 5 to deflect, so that the welding gun component 51 on the connecting shell 5 can be adjusted to the left and right angles, and the deflection motor 66 in the connecting shell 5 is started, and the front and rear angles of the welding gun component 51 can be driven to be adjusted through the transmission of the gear set;

[0058] After the adjustment is completed, the lifting plate 41 is pushed down by the adjusting hydraulic cylinder 4, which drives the welding gun component 51 to descend, so that the welding gun component 51 is close to the weld to be welded, and then the lifting hydraulic cylinder 7 on the lifting plate 41 is started to drive the wind shield 71 to descend to protect the welding place from wind. The welding gun component 51 is started, and the welding wire on the wire roller is pulled by the internal welding wire feeding system to weld the weld.
