Wall-climbing welding machine for shell plate of large-scale ship

The invention belongs to the field of marine robots, and particularly relates to a wall-climbing welding machine for a shell plate of a large-scale ship. The wall-climbing welding machine comprises a drive module, a magnetic vibration damping traction module and a carrying platform. The drive module is connected with the carrying platform through the magnetic vibration damping traction module, and the magnetic vibration damping traction module is arranged between the drive module and the carrying platform. The drive module comprises a gear crawler belt, a gear-driven wheel, a central frame and a motor. The carrying platform comprises a carrying holder, a permanent magnet box, and a guide wheel mechanism. The magnetic vibration damping traction module comprises symmetric magnetic fixing and connecting mechanisms which are fixed to two ends of a central connecting rod, and the magnetic fixing and connecting mechanisms are respectively fixed to one end of the central frame and one end of the carrying platform. The wall-climbing welding machine for the shell plate of the large-scale ship is relatively simple in structure, easy to use, easy to popularize to ship manufacturing enterprises, so the wall-climbing welding machine is good in business prospect.
