Abstract

The invention discloses an automatic rust removing method for a large splicing seam of a ship hull plate. The method comprises following steps: step one, measuring shape, length and width of a splicing welding seam to be subjected to sand blasting; step two, mounting a wall-climbing robot and a sand blasting gun, and mounting a visual camera on the wall-climbing robot; step three, arranging chaincircuits along two sides of the splicing welding seam of the ship hull plate, and realizing meshed connection between chain wheels on two sides of the wall-climbing robot with the chain circuits; stepfour, connecting the visual camera to an intelligent control system; and step five, enabling the sand blasting gun to perform reciprocating swing in a certain angle range during climbing of the wall-climbing robot so as to perform sand-blasting rust removal on the splicing seam. A visual feedback mode is adopted to replace a traditional overhead working truck to cooperatively regulate and controltechnological parameters and correct a motion path of the robot, labor cost is greatly reduced, efficiency, safety and convenience in operation and accessibility are improved, convenience and accuracy of remote accurate regulation and control of the technological parameters and the motion path are improved.

Description

technical field [0001] The invention belongs to the technical field of ship painting and manufacturing, and in particular relates to an automatic derusting method for large splicing seams of hull panels. Background technique [0002] The painting work of the hull sections can be carried out in the workshop, but after the tailor welding of the hull sections, it can only be painted at the dock site due to its large size. The second is to make the surface reach a certain roughness. Nowadays, artificial sandblasting is usually used for surface cleaning treatment, but the weld seam of the hull subsection assembly is very long, the sandblasting workload is large, the efficiency is low, the labor intensity is high, the working conditions are harsh, and the dust and noise are harmful to people. significant health impact. In addition, the dust after manual grinding is not recycled, and it will directly fall into the dock and be discharged into the sea, which will also cause serious...
