Description

Technical Field

[0001] The utility model belongs to the technical field of flaw detectors, and in particular relates to a walking mechanism of an X-ray flaw detector. Background Art

[0002] X-ray flaw detectors are devices that use the properties of X-rays that penetrate and attenuate materials to detect defects. The images on the X-ray film directly and accurately reflect the presence, location, shape, and size of defects in the inspected object. They can perform internal inspections on objects that appear intact and are widely used in industries such as machinery, chemicals, shipbuilding, automobiles, and refractory materials.

[0003] X-ray flaw detector is one of the important equipment for non-destructive testing. It can be used to detect internal defects of metal and non-metal materials and their products, such as pores, slag inclusions and incomplete penetration in welds. However, the X-ray flaw detector is large in size and weight, and the same point of the inspected object needs to be circumferentially transilluminated several times. Currently, most of the X-ray flaw detectors are stabilized by temporary positioning. After the transillumination is completed, the X-ray flaw detector is positioned on the other side of the inspected object, which requires the staff to repeatedly position the X-ray flaw detector, resulting in low work efficiency. In view of this, the utility model is proposed to provide an X-ray flaw detector walking mechanism to solve the above problems. Utility Model Content
