Abstract

The invention provides a local dry-method underwater welding robot based on an ROV. The local dry-method underwater welding robot comprises the ROV and a welding mechanical arm installed on the ROV. The ROV comprises a frame, a vertical auxiliary thruster, a vertical main thruster and a horizontal thruster, wherein the vertical auxiliary thruster, the vertical main thruster and the horizontal thruster are installed on the frame, the upper portion of the frame is provided with buoyancy materials, the middle portion of the frame is provided with an electronic device sealed cabin and a welding device sealed cabin, the front of the frame is provided with an imaging sonar and an underwater lighting device, the two sides of the frame are provided with camera systems, and the bottom of the frame is provided with a pipeline fixing claw, a hydraulic pile leg and an underground hydraulic pump. The ROV is connected with a water surface control system on a mother ship through a funicle cable. The front portion of the welding mechanical arm is provided with a local dry-method arc welding gun and a weld tracker. The local dry-method underwater welding robot is high in working efficiency, large in working depth, good in underground welding flexibility and especially suitable for being used in the nuclear radiation or poisonous and harmful underwater, the atmospheric environment or in the site where workers cannot arrive at.

Description

technical field [0001] The invention relates to an underwater welding device, in particular to an ROV-based underwater welding robot. Background technique [0002] In recent years, with the increase in the construction of marine structures, the assembly and maintenance of underwater related facilities have put forward higher requirements for underwater welding technology. At present, the quality, efficiency and automation of underwater welding are far from meeting people's requirements. A large part of underwater welding is still completed by divers, which is not only inefficient but also dangerous. In order to ensure the quality of underwater welding, reduce production costs, improve production efficiency, and break through the depth limit of underwater welding, it is necessary to develop and develop underwater welding robots. [0003] The underwater welding robot is a special robot, which is produced by the combination of underwater welding technology and underwater robot...
