[0067] When conducting the inspection of columnar civil structures, when the inspection component enters the middle of the integrated positioning frame 1 and the combined positioning frame 202, the cooperating electric slide rail 301 drives the cooperating electric push rod 302 to rotate and change positions along the bottom ends of the integrated positioning frame 1 and the combined positioning frame 202. The cooperating electric push rod 302 drives the cavity fixing block 303 to move. At the same time, the cooperating motor 304 drives the C-shaped position-changing block 305 and the elastic extrusion strip 306 to rotate and align along the cavity fixing block 303, so that the side end of the elastic extrusion strip 306 is aligned with the side end of the inspection component. The cooperating electric push rod 302 drives the elastic extrusion strip 306 to fit against the side end of the inspection component, realizing the alignment and fixation of the integrated positioning frame 1 and the combined positioning frame 202. Then, the incoming and outgoing electric push rod 201 drives the integrated positioning frame 1 and the combined positioning frame 202 to fit with each other, realizing alignment and clamping, facilitating position correction and improving the accuracy of inspection alignment;

[0068] After the alignment is completed, the alignment motor 210 drives the combined alignment strip 209 to rotate along the correction convex frame 208, so that the top end of the correction convex frame 208 fits against the bottom end of the combined alignment strip 209. Then, the alignment motor 210 drives the combined alignment strip 209 to rotate along another combined alignment strip 209, so that the top ends and the bottom ends of the two groups of combined alignment strips 209 fit together. Through the mutual magnetic attraction and clamping of multiple fixed electromagnets 212, the correction convex frame 208 and the combined alignment strip 209 are magnetically fixed. The two groups of semi-circular electric slide rails 203 drive the two groups of position-changing moving strips 204 to rotate and move along the integrated positioning frame 1 and the combined positioning frame 202 respectively. The alignment electric slide rail 205 drives the T-shaped alignment block 206 to move along the position-changing moving strip 204, so that the T-shaped alignment block 206 fits against the side end of the inspection component, realizing stable alignment. And by adjusting the position of the combined alignment strip 209, the horizontal and vertical inspection switching is realized, so as to operate on civil buildings in different inspection environments and improve the inspection application range;

[0069] When the T-shaped alignment block 206 fits against the side end of the inspection component, the correction electric slide rail 207 drives the correction convex frame 208 to move along the T-shaped alignment block 206. The clamping electric slide rail 211 drives the lifting alignment frame 213 to move up and down along the correction convex frame 208 and the combined alignment strip 209, thereby driving the connection electromagnet 215 and the I-shaped clamping block 216 to move. The alignment electric slide rail 217 drives the correction processing frame 218 to move along the I-shaped clamping block 216, thereby driving the horizontal seam detector 219, the vertical seam detector 220 and the depth detector 221 to move, so that the curved surface and the special-shaped surface can be adjusted and inspected during the inspection, improving the accuracy and efficiency of inspection alignment. By continuously moving, the cracks in the civil structure are measured and processed, and through the linkage cooperation of multiple measuring instruments, stable measurement and processing are realized, ensuring the accuracy and efficiency of crack measurement;

[0070] The correction motor 223 and the correction transmission box 222 drive the processing electric push rod 224 to rotate, and the processing electric push rod 224 drives the processing inner hole block 225 to be lifted and lowered. The rotating motor 226 drives the rotating processing frame 227 to rotate along the processing inner hole block 225, and the in-and-out electric slide rail 228 drives the extrusion and laminating frame 229 to move along the rotating processing frame 227, and the side ends of the multi-slot elastic plate 230 and the scrubbing processing pad 231 are attached to the side ends of the civil structure, and the clamping electric slide rail 211 is used to drive the scrubbing processing pad 231 to be lifted and lowered to scrub the surface, and the barrel retracting and retracting electric motor 232 drives the take-up drum 233 to rotate, and the take-up drum 233 drives the retracting and releasing rope 234 to be retracted and released. At this time, the multi-slot elastic plate 230 is retracted and released, so that the angle of the scrubbing processing pad 231 can be adjusted, so that the best alignment scrubbing effect can be guaranteed during cleaning;

[0071] The linkage motor 214 drives the connection electromagnetic block 215 and the type clamping block 216 to rotate and change position, and the two sets of connection electromagnetic blocks 215 switch the magnetic attraction to adjust the position and angle of the type clamping block 216. The alignment electric slide rail 217 drives the linkage processing frame 235 to move along the type clamping block 216, and the fitting electric push rod 236 drives the ultrasonic detector 237 to fit to the side end of the civil structure. The ultrasonic detector 237 is used to perform ultrasonic detection of cracks in the civil structure, so as to achieve steady measurement and processing and ensure the accuracy of the data.
