Wall-climbing grinding robot for steel large container

Abstract

The invention relates to the field of mechanical automatic engineering, and aims to provide a wall-climbing grinding robot for a steel large container. The wall-climbing grinding robot can automatically grind a workpiece, reduces manual operation labor amount, can be adsorbed onto curved surfaces such as a wall surface, a spherical surface and a pipeline to perform climbing grinding operation, andperforms perpendicular across-welding-seam back-and-forth grinding according to practical grinding requirements of a welding seam, and a grinding process cannot meet requirements, on grinding, of nondestructive testing related standards. According to the technical scheme adopted by the invention, the wall-climbing grinding robot for the steel large container is characterized in that the grindingrobot comprises a travelling vehicle body for climbing on the wall part of the container, a grinding platform which is hinged onto the travelling vehicle body through a connecting rod group and is parallel to the travelling vehicle body, a grinding mechanism which is mounted onto the grinding platform, a correcting and front video detecting system which is mounted at the front end of the grindingplatform, a control box and rear video detecting system which is mounted on the travelling vehicle body, and an operating table which is electrically connected to the control box through a cable, andis positioned outside.

Description

technical field [0001] The invention relates to the field of mechanical automation engineering, in particular to a wall-climbing and grinding robot for large steel containers. Background technique [0002] Large steel vessels usually work in harsh environments such as high pressure and corrosion, and their safety and reliability are of paramount importance. Due to the internal pressure of the tank and the erosion of rainwater and oil, the tank wall may have pits, cracks, holes and other defects. These defects will not only cause storage leakage, but may even cause explosions and fires. Therefore, regular inspections must be carried out. At present, most of the detection of large containers is done manually, and scaffolding needs to be built inside and outside the tank, which has the disadvantages of high cost, high labor intensity for operators, dangerous operation and low efficiency. The wall-climbing robot organically combines the ground mobile robot technology with the a...

Problems solved by technology

[0004] However, the existing wall-climbing grinding robot has the following disadvantages: it is not designed according to the actual grinding requirements of the weld, the grinding process does not meet the requirements of the relevant non-destructive testing standards for grinding, and does not consider factors such as weld shape characteristics, different service conditions, etc.
