Description

Technical Field

[0001] The utility model belongs to the technical field of probe brackets, and in particular relates to a rotary flaw detector probe bracket. Background Art

[0002] Rail flaw detectors are instruments that detect hidden flaws inside rails or small cracks on the surface, especially those that are partially covered by plywood. According to the working principle of flaw detection, there are two categories: electromagnetic flaw detection and ultrasonic flaw detection. Ultrasonic flaw detectors are widely used in China's railways. Ultrasonic waves can propagate at different speeds in solids and liquids, but can hardly propagate in the air. When ultrasonic waves are emitted into rails with core flaws, cracks or other damage, they are blocked at the contact section between the solid and the air, generating reflected waves.

[0003] Most of the flaw detector probe brackets in the prior art cannot adjust the angle well, resulting in a relatively fixed detection angle of the flaw detector probe, which is inconvenient to adjust. Utility Model Content
