Time-of-flight diffraction ultrasonic scanning bracket

The invention discloses a time-of-flight diffraction ultrasonic scanning bracket, which comprises roller modules and probe clamping modules, and also comprises two slide connecting rods and a rotary connector, wherein one end of each slide connecting rod is respectively fixedly connected with the rotary connector, the rotary connector is provided with a locking handle, each sliding connecting rod is provided with the roller modules and the probe clamping modules, and the roller modules and the probe clamping modules can slide along the slide connecting rods and can be locked onto the slide connecting rods. The two slide connecting rods are connected with each other through the rotary connector, so the angle between the two slide connecting rods can be convenient to change and the installation position of each roller module and the installation position of each probe clamping module can be adjusted according to real requirement, so the probe distance can be adjusted at will within a certain range. The application range of the scanning bracket can be enlarged. The time-of-flight diffraction ultrasonic scanning bracket can be widely used for detecting multiple weld seams such as a flat weld seam, a longitudinal weld seam of a straight tube, a weld seam of a reducer tube, an angle weld seam and the like under the situation that the detection space is restricted.
