Problems solved by technology
The crack will slowly develop in depth under the action of stress, and when it exceeds its limit value, it will expand rapidly and break, which will bring hidden dangers to the safe production of the enterprise, and in serious cases will lead to major accidents
[0003] Therefore, to eliminate the hidden dangers of stainless steel bolts in service, the most effective way is to carry out online safety inspection of stainless steel bolts. At present, the online inspection methods of stainless steel bolts include ultrasonic testing and ultrasonic phased array testing. Because ultrasonic testing is difficult to determine the location of defects, the testing results cannot be used. For the evaluation of defects, ultrasonic phased array detection is mostly used at present, but there is currently no relevant research and equipment development in China

The invention discloses a phased array testing scanner of in-service stainless steel bolts. The phased array testing scanner comprises three parts, namely a fixed seat assembly, a scanning seat assembly and an encoder assembly. The fixed seat assembly comprises a fixed seat and fixed seat fastening screws. The scanning seat assembly comprises a scanning seat, a phased array probe, a probe fastening handle, a limit ball, a limit spring and limit spring adjusting screws. The encoder assembly comprises an encoder fixed seat, an encoder, an encoder roller, an encoder locking ring, two encoder locking ring mounts, an encoder tension spring, encoder tension spring adjusting screws and encoder fixed seat fastening screws. The phased array testing scanner is easy to operate; the probe can move to be adjusted and is convenient for allocation and alignment of a test piece; and the encoder assembly can rotate 360 degrees for scanning record to realize phased array repeatable testing of in-service stainless steel bolts.
Description
technical field [0001] The invention relates to a phased array detection device, in particular to a phased array detection and scanning device and a detection and scanning method for in-service stainless steel bolts. Background technique [0002] Stainless steel bolts are important fastening parts between equipment components. Due to the large pre-tightening force applied during installation, the fatigue load of some stainless steel bolt connections, and environmental corrosion, stainless steel bolts may be damaged during use. Defects such as cracks occur. Cracks will slowly develop in depth under the action of stress, and when they exceed their limit values, they will rapidly expand and break, which will bring hidden dangers to the safe production of enterprises, and in severe cases will lead to major accidents. [0003] Therefore, to eliminate the hidden dangers of stainless steel bolts in service, the most effective way is to carry out online safety inspection of stainle...
