8. The method of using the adjustable pressure vessel nondestructive inspection device of claim 1, comprising the steps of:
s1, firstly, conveying a pressure container to be detected into a material passing hole (411) through a conveyor belt (6) on one side, simultaneously starting a second motor (404) to enable two screws (405) to rotate simultaneously, sliding a first sliding plate (406) to one side of the material passing hole (411) under the limiting condition of sliding connection with a rotating plate (402), and simultaneously driving a second gear (403) meshed with the first gear to rotate by a first rack (408) to enable a second rack (409) to drive a second sliding plate (407) to synchronously slide to one side of the material passing hole (411), so that four first electric rotating rollers (410) are enabled to position the center of the pressure container;
s2, starting a first motor (303) to drive a first gear (304) to rotate, and under the limit of a sliding frame (302), the first gear (304) meshed with a ring rail (301) can drive a flaw detector body (305) to revolve around a pressure container to perform flaw detection operation on two ends of the pressure container;
s3, synchronously starting the two fourth motors (502) to respectively drive the two folding connecting rods (509) in the two limiting mechanisms (5) to rotate, simultaneously pushing the two bending pieces (505) to translate towards one side far away from the mechanical box (501) through the connecting rods (508) at the top ends of the folding connecting rods (509), and when one pulley (504) reaches the end of one end of the sliding groove (503), the other pulley (504) slides towards the arc groove at one side to the end under the action of the rotating force of the folding connecting rods (509), so that the two limiting plates (506) in the two limiting mechanisms (5) are simultaneously turned for 90 degrees to limit the pressure container;
s4, meanwhile, the third motor (412) drives the rotating plate (402) to rotate 90 degrees clockwise, so that the port of the pressure container faces upwards to be in a vertical state, the four first electric rotating rollers (410) are started to drive the pressure container to be completely arranged in one side opposite to the two limiting plates (506), the second motor (404) close to one side of the pressure container is continuously started, the bottom of the pressure container can be lapped on the two first electric rotating rollers (410) with the reduced distance, the two fourth motors (502) are reversely operated, the two limiting plates (506) can be reset, and under the cooperation of the electric lifting rods (2), the flaw detector body (305) can perform surrounding detection on the outer surface of the pressure container from bottom to top;
and S5, when the detection is finished, limiting the outer wall of the pressure container through the limiting plate (506), enabling the rotating plate (402) to rotate anticlockwise for 90 degrees through the third motor (412) to reset, starting the second electric rotating roller (507), enabling the second electric rotating roller to drive the pressure container to convey to the surface of the other conveyor belt (6), finishing the blanking, and carrying out the next round of flaw detection.
