7. A bridge pile foundation nondestructive testing device according to claim 6, characterized in that: A support frame (184) is fixedly mounted on the surface of the semicircular plate (6), a rotating plate (185) is rotatably mounted on the inner wall of the support frame (184), a long plate (186) is fixedly mounted on the top of the rotating plate (185), and a limiting plate (187) is fixedly mounted on the surface of the long plate (186).

8. A bridge pile foundation nondestructive testing device according to claim 7, characterized in that: The limit block (182) is arranged at the bottom of the barb (11), and a first torsion spring is arranged between the support frame (184) and the rotating plate (185).

9. A method for using a bridge pile foundation nondestructive testing device, using the bridge pile foundation nondestructive testing device according to claim 8, characterized in that: The following steps are involved: Step 1: The hook lock rope (10) is lowered by rotating the lifting device (3) so that the hook lock rope (10) hooks the barb (11), and then the semicircular plates (6) are docked. During the docking process, the fixing block (13) is inserted into the hollow frame (12) to achieve guidance, and the docking efficiency can be improved by the guidance; Step 2: When the fixed block (13) is inserted into the hollow frame (12), the elastic telescopic block (14) and the trapezoidal block (15) are driven to move into the hollow frame (12). When the trapezoidal block (15) moves into the hollow frame (12), it contacts the surface of the hollow frame (12). The trapezoidal block (15) is squeezed by the hollow frame (12) and shrinks inward. At the same time, when the trapezoidal block (15) overlaps with the slot, the elastic telescopic block (14) drives the trapezoidal block (15) to move upward to clamp the hollow frame (12), thereby preventing the fixed plates (7) from separating and affecting the docking effect. Step 3: By rotating the bolt (8), the two fixing plates (7) are fixed together by using the bolt (8) and the nut (9) to prevent the semicircular plate (6) from being disconnected during the lifting process, thereby affecting the detection effect. At the same time, the lifting device (3) is started to rotate to drive the hook lock rope (10) to reel in, and the hook lock rope (10) reeling in drives the barb (11) to move upward, and the barb (11) moves upward to drive the semicircular plate (6) to move upward; Step 4: The semicircular plate (6) is moved upward to drive the vibration detection device (61) to move upward, and the vibration detection device (61) is moved upward to detect the surface of the bridge pile basic body (1), so as to detect hidden dangers on the bridge pile basic body (1), so that the bridge pile basic body (1) can be repaired in time, thereby improving the service life of the bridge pile basic body (1).
