Abstract

The application provides a detecting device for a large ring and a ring detecting method, and belongs to the technical field of ultrasonic nondestructive testing. The detecting device comprises the following parts of a water tank equipped with a coupling agent and used for placing a ring; a rotating mechanism rotatably installed in the water tank, wherein the ring is arranged on the rotating mechanism; a bridge, of which both ends are arranged on peripheries of two opposite sides of the water tank and capable of moving along the length direction of the two side walls of the water tank; and an ultrasonic scanning mechanism comprising a sliding trolley and an ultrasonic detecting assembly, wherein the sliding trolley is movably mounted on the bridge in the axial direction of the bridge and located above the water tank, and the ultrasonic detecting assembly is mounted up and down on the sliding trolley for detecting internal defects in the ring. The detecting device can accurately and comprehensively test rings, and can adapt to the detection of the rings of different sizes, thereby improving the detection efficiency of the rings and the accuracy of detecting the data.

Description

technical field [0001] The present application relates to the technical field of ultrasonic nondestructive testing, and in particular to a testing device and a ring testing method for large rings. Background technique [0002] Large-scale rings are widely used in wind power generation, power transmission, ship equipment, engineering machinery, metallurgical machinery and other industries. Ring rolling is one of the main methods of ring processing and production. During the rolling process, rings are prone to Various types of defects, when the defect size exceeds the standard, the performance of the ring will be greatly affected, causing safety hazards. [0003] Ultrasonic flaw detection is the most common method for detecting internal defects of rings. At present, ultrasonic testing of rings is mainly manual hand-held inspection. Manual inspection is easily affected by the operating experience of inspectors, resulting in detection errors and low detection efficiency; large r...
