Problems solved by technology

This detection method is very harmful to the operators. The nuclear radiation site has a great impact on the personal safety of the operators, high labor intensity, and low detection efficiency. It may be different, and the quality of the test cannot be guaranteed
PS-Scan4 produced by Force Company of Denmark is a plug-in weld detection system, which is an expensive, remote-controlled ultrasonic detection system, which can detect welds formed by plug-in intersecting pipes. However, its robot installation adopts a fixed-diameter clamp ring to adapt to online and in-service pipeline installation, and its adaptability to the detection of variable-diameter pipelines is poor, which greatly limits the application of this insertion weld detection system.

Embodiment Construction

[0014] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 figure 2 As shown, the split circular rotation mechanism is mainly composed of motor 11, planetary pinion 10, upper and lower connecting plates 4, large gear ring 6, quick positioning connecting device 8, connecting bolts 5 and other main components; the robot arm is mainly composed of six free It consists of main components such as robot arm 3 and ultrasonic transducer 2. The six-degree-of-freedom robot arm 3 realizes the position control and attitude control of the ultrasonic transducer.

[0016] The structural connection relationship of each part is as follows: the split fixed support 9 and the large gear ring 6 are connected as a whole by bolts 7, the upper and lower connecting plates 4 are connected as a whole by bolts 5, and the flanges of the motor 11 are fixed on the upper and lower connecting plates 4, the ...

Abstract

The robot automatic detection system for extra-long pipeline welding seam includes three portions of partial type fixing support seat, partial type periphery-directional rotating mechanism and robot arm. The partial type fixing support seat adopts movable slide block structure, the partial type periphery-directional rotating mechanism is formed from motor, planetary pinion, large teeth ring and upper and lower connecting plates. The partial type fixing support seat is fixed on the detected branch pipe by means of fast positioning connecting device so as to form mounting platform of said detection system and location reference, and the partial type periphery-directional rotating mechanism is mounted on the platform.

Description

Technical field: [0001] The invention relates to a robot automatic detection system for welding seams of intersecting pipelines, which is suitable for industries such as nuclear energy, chemical industry, oil, gas and water transportation. It can be installed on the pipeline to be inspected, and in a safe environment far away from the inspection site, the robot system can be operated and controlled by remote control technology to complete the automatic inspection of vertically intersecting pipe welds, eliminating the labor-intensive and labor-intensive inspections caused by the manual inspection process. Problems such as low efficiency, difficulty in guaranteeing detection quality, and damage to operators caused by nuclear radiation environment. It belongs to the field of electromechanical technology. Background technique: [0002] Nuclear energy, chemical industry, oil, gas and water transportation and other industries have a large number of plug-in intersecting pipelines....
