Underwater grinding and dust removing robot

Abstract

The invention discloses an underwater grinding and dust removing robot. The robot comprises a robot shell, a chassis, a driving mechanism, an attraction mechanism, a grinding lifting mechanism, a grinding mechanism, a dust sucking mechanism, a monitoring system and a control system; the chassis is connected with the driving mechanism, the grinding lifting mechanism and the control system, the attraction mechanism comprises a permanent magnet block and propellers, the permanent magnet block is installed in a crawler belt of the driving mechanism, and the propellers are installed on the upper surface and the rear surface of the robot shell; the grinding mechanism is connected with the grinding lifting mechanism, and the dust sucking mechanism is connected with the grinding mechanism; the robot shell is installed on the chassis; and the monitoring system is installed on the upper surface of the robot shell. According to the robot, grinding pretreatment can be conducted on the surface of a weld joint before welding and after welding underwater, the robot has good attraction capacity and moving capacity and can be reliably attracted to the surface of welded metal, all mechanisms of the robot are matched with one another, it can be guaranteed that the grinding process is stable, and the robot has certain dust removal capacity.

Description

technical field [0001] The invention relates to a robot technology, in particular to an underwater grinding and dust removal robot. Background technique [0002] With the gradual shortage of natural resources on land, the ocean has become an important field of industrial and information development in this era, and ocean development has entered a new stage. In the future, more offshore projects will appear in my country's waters, and the construction and development of marine projects will be in full swing. At the same time, underwater welding technology will gradually be used in large quantities. [0003] Weld grinding is an important task before and after welding. Grinding before welding can remove impurities such as rust, dust, oil, etc., and improve welding quality. Grinding after welding can make the surface of the weld joint smooth and smooth, which can not only eliminate the influence of stress concentration, prevent cracks at the joint, but also serve The process p...

Problems solved by technology

[0004] In the prior art, when performing underwater grinding, the manual grinding task has high work intensity, the grinding environment is harsh, and the quality of manual grinding is easily affected by various factors such as workers' emotions, physical strength, technology, etc., and the production efficiency and product quality cannot be guaranteed.

Secondly, many residues will be produced after manual polishing, which will cause great pollution to water quality.
