The working principle is as follows: the user assembles the first ring piece 9 and the second ring piece 12 through the matching of the handle screw 27, the connecting arm 13 and the special-shaped self-locking nut 34 according to the diameter of a detected pile foundation, in the assembling process, the balls 29 and the detection piece 33 on the inner sides of the first ring piece 9 and the second ring piece 12 are tightly attached to the pile foundation, then the first ring piece 9 and the second ring piece 12 which are arranged in a circumferentially staggered array are locked and fixed through the meshing of the handle screw 27 and the special-shaped self-locking nut 34, the user penetrates through the transmission threaded rod 8 through the meshing of the first ring piece 9 and the limiting ring 10 and the transmission threaded rod 8, the user adjusts the positions of the first fixing frame 4 and the second fixing frame 36 according to the position of the transmission threaded rod 8, after the adjustment is completed, the user enables the lower end of the transmission threaded rod 8 to be correspondingly embedded on the inner sides of the first coupler 7 and the second coupler 37, the transmission threaded rod 8, the first coupler 7 and the second coupler 37 are locked and fixed, a user starts the motor 5 through the operation plate 2, the transmission threaded rod 8 is driven under the matching of the transmission belt 6 and the guide wheel 14, the detection annular structure is attached to and rises from the bottom to the top on the surface of the pile foundation under the meshing of the transmission threaded rod 8 and the first ring piece 9, the limiting ring 10 is limited through the optical axis 19 and the limiting ball 22 in the rising process of the first ring piece 9 and the second ring piece 12, the limiting ring 10 drives the cleaning brush 21 to rotate, dust in the area of the surface of the pile foundation is swept, the detection precision of the detection piece 33 is ensured, the limiting ring 10 pushes the push rod 23 upwards when the detection annular structure is detected to be completed, the piston 24 extrudes the protection liquid in the material barrel 11, and the protection liquid enters the fan-shaped spraying piece 26 through the communicating pipe 25, finally, the spraying is carried out on the pile foundation through the fan-shaped spraying piece 26, and the protection treatment is carried out on the pile foundation.

To sum up, the nondestructive testing method and the nondestructive testing device for the bridge pile foundation have the advantages that through the matching of the handle screw 27, the special-shaped self-locking nut 34 and the first ring piece 9 and the second ring piece 12, a user can assemble and fix the first ring piece 9 and the second ring piece 12 according to the diameter of the pile foundation, the balls 29 and the testing pieces 33 in the first ring piece 9 and the second ring piece 12 are enabled to be attached to the surface of the pile foundation to move upwards through the driving of the motor 5 to the transmission belt 6, the testing pieces 33 can test multiple parts of the pile foundation in the moving process, and then testing signals are transmitted to the device main body 1, so that the testing precision of the device main body 1 is ensured; through the matching of the optical axis 19, the limiting ball 22, the cleaning rod 20 and the cleaning brush 21, when the first ring piece 9 moves upwards, the limiting ring 10 is limited through the optical axis 19 and the limiting ball 22, so that the limiting ring 10 is meshed and rotates on the surface of the transmission threaded rod 8, the cleaning rod 20 and the cleaning brush 21 which are arranged in a circumferential array are driven to rotate rapidly when the first ring piece rotates, the cleaning brush 21 can brush dust on part of the surface of the pile foundation, and the cleaning brush 21 can clean the detection path of the detection piece 33 because the limiting ring 10 and the detection piece 33 are positioned on the same vertical plane; through the cooperation of storage bucket 11 and piston 24 and push rod 23 and fan-shaped spraying piece 26, the user is before starter motor 5, add storage bucket 11's inside with protective liquid in advance, when ring 9 and No. two rings 12 rose gradually, spacing ring 10 can upwards promote push rod 23, push rod 23 rebound can make piston 24 extrude the inside protective liquid of storage bucket 11, make protective liquid pass through the inside that communicating pipe 25 got into fan-shaped spraying piece 26, spray protective liquid on the pile foundation by fan-shaped spraying piece 26 at last, protect the pile foundation and handle.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
