Single-group probe scanning frame for small-diameter pipe ultrasonic diffraction time difference method detection

The utility model relates to a single-group probe scanning frame for small-diameter pipe ultrasonic diffraction time difference method detection; a pair of probe wedge clamping components are arranged on an industrial aluminum profile upper beam, the industrial aluminum profile upper beam is provided with a handle, and the spacing between the wedge clamping components is adjustable; each wedge clamping component comprises a spring, an optical axis, a connection block and a wedge boot; a magnet is arranged in the wedge boot, a wedge which is processed to be matched with the curvature of a detected pipe, both ends of the aluminum profile upper beam are provided with scanning frame fixing components, each scanning frame fixing component comprises two connecting rods with adjustable positions, and the tail end of each connecting rod is provided with a magnetic rolling wheel; and the utility model has the benefits that: (1) the single-group probe scanning frame for small-diameter pipe ultrasonic diffraction time difference method detection has a wide scope of application to the diameters of detected pipes, and is particularly applicable to the ultrasonic diffraction time difference method detection of small-diameter pipes; (2) the coupling between a probe wedge and a work piece is good, and the defects in a detected area can be effectively discovered; and (3) the cost is low.
