After the fixed ring 3 drives the movable seat 32 and the welding mechanical arm 31 to move to a certain position, the welding mechanical arm 31 starts to weld the joint of the first precast pile 1 and the second precast pile 2, in the welding process, the first motor 326 is started, the rotating shaft 327 is driven by the rotation of the output shaft of the first motor 326 to rotate, the rotating shaft 327 rotates to drive the gear 328 to rotate, the rotation of the gear 328 moves along the outer surface of the toothed ring 325 through meshing with the toothed ring 325, and meanwhile, the sliding blocks 335 and the clamping blocks 323 on the movable seat 32 are respectively clamped with the inner surfaces of the first annular groove 321 and the second annular groove 322 in a sliding manner, so that the movement of the movable seat 32 is limited, and the movement of the gear 328 drives the movable seat 32 to move on the fixed ring 3 along the outer surface of the fixed ring 3.
The welding mechanical arm 31 is driven to move by the movement of the moving seat 32, so that the welding mechanical arm 31 is driven to comprehensively weld the joint of the first precast pile 1 and the second precast pile 2.
During the moving of the moving seat 32, when the moving seat 32 is about to contact with the arc-shaped clamping plate 44, the piston rod of the hydraulic cylinder 43 contracts to drive the arc-shaped clamping plate 44 to separate from the first precast pile 1 and the second precast pile 2, so as to facilitate the welding of the joint of the first precast pile 1 and the second precast pile 2 by the welding mechanical arm 31.
As shown in the figures 7 and 8, the complete fixing ring is formed by the semi-annular fixing ring, and the welding machine can be carried by a carrying vehicle in the using process, so that the welding machine is very convenient to operate and shift, and the problems of large size, inconvenience in operation and the like of the conventional welding machine are solved.
