Full water immersion type ultrasonic flaw detection equipment for annular workpiece

The utility model relates to full water immersion type ultrasonic flaw detection equipment for an annular workpiece, which automatically positions the annular workpiece through a stop depended wheel assembly and a clamping depended wheel assembly and drives the annular workpiece to rotate through a second hydraulic motor and a stop depended wheel. Due to the fact that the clamping force is adjustable, the annular workpiece rotates more stably and is not prone to slipping. And moreover, the first hydraulic motor and the second hydraulic motor are hydraulic execution elements, are simple to control, have no leakage short circuit risk, and can be immersed in water, so that the flaw detection effect of the ultrasonic probe is improved. And meanwhile, the overall structure is simple, and all main components are standard components, so that the manufacturing and maintenance cost of the equipment is greatly reduced. During detection, the ultrasonic probe can detect the workpiece on the side, close to the stop depend
