Embodiment Construction

[0019] see Figure 1-3 , the present invention provides an automatic ultrasonic scanner for large workpiece welds, comprising a main frame I1 and a main frame II2, the main frame I and the main frame II are arranged left and right, and magnetic wheels 8 are respectively installed below them, and the magnetic wheels The wheels are two groups of left and right, and each group includes two front and rear magnetic wheels. The magnetic wheels of each group are respectively connected under the main frame I and the main frame II through their respective magnetic wheel frames. The main frame I and the main frame The IIs are connected by an adjustable connection that can adjust the mutual longitudinal rotation angle. Thus by changing the longitudinal angle between the main frame I and the main frame II, the inclination angle between the left and right magnetic wheels respectively installed under the main frame I and the main frame II can be changed to adapt to workpieces with different...

Abstract

The invention relates to an automatic ultrasonic scanner for welding lines of large workpieces, which comprises a main frame I and a main frame II which are arranged on the left and right; the lower parts of the main frame I and the main frame II are respectively provided with magnetic wheels; and the main frame I and the main frame II can be connected in an adjustable connection mode capable of adjusting mutual longitudinal rotation angles. The automatic ultrasonic scanner can realize mutual longitudinal rotating adjustment at any angle between the two main frames so as to adapt to the walking and working of the scanner on workpieces to be detected with different surface shapes, and is mainly used for detecting the welding lines of the large workpieces.

Description

technical field [0001] The invention relates to an automatic ultrasonic scanner for welding seams of large workpieces, which is mainly used for detecting the welding seams of large workpieces. Background technique [0002] Welded structures are an integral part of huge industrial wealth. According to the estimation of the United States, the economic loss caused by the failure of welded joints is as high as 5% of the gross national product. Therefore, how to ensure the safe operation of welding workpieces has become a very challenging subject. Non-destructive testing is the main means to find welding defects. At present, the industrial sectors that use non-destructive testing in my country include machinery manufacturing, petrochemical pressure vessels and pipelines, metallurgical enterprises and shipbuilding industries, nuclear energy fields and oil production platforms, and railway transportation departments. [0003] At present, the weld detection of large workpieces is g...
