Abstract

The invention discloses an ultrasonic flaw detection robot for a large spherical tank steel vessel. The ultrasonic flaw detection robot comprises a robot body, an image acquisition device, an adsorption device, a flaw detection device and a control system, the robot body comprises a machine body frame and an elastic connection structure, the adsorption device is arranged at the lower part of a machine body, the flaw detection device is arranged at the front part of the machine body, the control system is arranged inside the machine body, the image acquisition device is used for acquiring weldjoint features and transmitting the acquired images to the control system for processing, and the control system receives the images acquired by the image acquisition device and extracts center linesby identifying weld joints on the wall surface of the vessel so as to achieve the function that the robot moves and performs detection according to the center lines. The robot can move to automatically search the weld joints in the wall surface, can perform flaw detection on the weld joints at the same time and can replace manpower to perform high-position operation, and therefore the risk of manual operation is avoided, the robot is flexible in action on the metal wall surface, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of industrial special robots, and in particular relates to an ultrasonic flaw detection robot for steel containers of large spherical tanks. Background technique [0002] With the development of the industrial level, especially in the petrochemical industry, more and more large steel containers of spherical tanks are used in industrial production, and spherical tanks are used to store various flammable and explosive liquid and gas raw materials. Therefore, the requirements for its safety are getting higher and higher. The production of large spherical tanks is carried out through welding of various parts, and there will be many welds. There are many accidents caused by welds. In order to ensure the safety of the production process In order to ensure the safety, it is necessary to inspect the weld seam of the spherical tank container to check whether there are defects inside it. This kind of inspection has a...
