Plate 5 is clamped at the upper end. Because the relative position of the internal clapboard clamping alignment device and the bottom of the internal clapboard to be adjusted has been pre-adjusted, so the upper end of the clamped internal clapboard to be adjusted can be perpendicular to the bottom of the internal clapboard.

6. As shown in Figures 6E to 6G and Figures 17A and 17B, through the driving function of the web pressing claw driving device, the two web pressing claws 2532 drive the webs on both sides of the box girder to move toward each other inward , so that the contact surface between the web 7 to be adjusted and the inner partition 5 maintains an ideal assembly positioning gap.

After the base plate 3 has ensured the relative verticality and fits perfectly with the web plate 7, the external welding mechanical arm can be started to perform positioning welding of the external weld seam.

18. As shown in Figure 28, after the entire top plate is adjusted for verticality and fit and is welded with the web plate, start the control system of the top plate pressing mechanism again to make the pressing wheel mechanism go up. The pressure roller mechanism is locked by the hydraulic locking device set on the fixed frame of the pressure roller bracket so that it cannot go down by itself. Then start the traveling control system of the cart (the traveling speed of the cart is set in advance according to the welding speed of the external weld seam), and cooperate with the external welding robot arm to weld the entire external welding seam (there are four groups of external welding robot arms, which can be Weld the four external welds of the box girder).
