The alignment motor and the fixed electromagnet drive multiple groups of correction convex frames and combined alignment strips to be mutually clamped and connected. The clamping electric slide rail drives the lifting alignment frame, and the linkage motor drives the connecting electromagnet block and the I-shaped clamping block to rotate and commute. And through the switching processing of the connecting electromagnet block, when detecting and processing civil structures with different shapes, the position of the detection equipment can be corrected.

[0031] The correction transmission box and the correction motor drive the processing electric push rod and the processing inner hole block to rotate. The rotation motor drives the rotation processing frame to rotate. The access electric slide rail drives the extrusion fitting frame, the multi-groove elastic plate and the brushing processing pad to move. The retracting and releasing motor, the wire winding drum and the retracting and releasing rope are used to pull the multi-groove elastic plate to retract and release. Multiple-position synchronous brushing processing is used, and it is synchronously linked with the detection equipment to avoid impurities accumulating in the gap and causing errors in detection.

At the same time, multiple groups of internal and external detections are used in combination with cleaning components to clean and detect the civil structure, improving the accuracy of data and the efficiency of detection.

[0033] 2. A positioning support component is provided. The adjustment electric push rod drives the integrated positioning frame and the combined positioning frame to separate from and lift the load-bearing inner hollow column, adjusting the positions of the integrated positioning frame and the combined positioning frame. The inlet and outlet hydraulic cylinders drive the rotation cooperation frame and the transposition fixed roller to move, and the transposition fixed roller is used to drive the load-bearing inner hollow column, the special-shaped bearing frame, the integrated positioning frame and the combined positioning frame to move, so as to sleeved the integrated positioning frame and the combined positioning frame on the side end of the detection component, and sleevedly connect the detection component and the detection device.

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 onto the side end of the inspection component, realizing the alignment and fixation of the integrated positioning frame 1 and the combined positioning frame 202.

[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 with 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 respectively 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. 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 onto the side end of the inspection component, realizing stable alignment. And by adjusting the position of the combined alignment strip 209, the switching between horizontal and vertical inspections 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 onto 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 connecting electromagnet block 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 during the inspection, the curved surface and the special-shaped surface can be adjusted and inspected, 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 and cooperation of multiple measuring instruments, stable measurement processing is 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 rise and fall. 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 fitting frame 229 to move along the rotating processing frame 227, so that the side ends of the multi-slot elastic plate 230 and the scrubbing processing pad 231 are fitted to the side ends of the civil structure, and the engaging electric slide rail 211 is used to drive the scrubbing processing pad 231 to rise and fall to scrub the surface, and the barrel retracting and retracting motor 232 drives the take-up drum 233 to rotate, and the take-up drum 233 is used to drive the retracting and releasing rope 234 for retraction and release. 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 and scrubbing effect can be guaranteed during cleaning;

[0071] The linkage motor 214 drives the connecting electromagnetic block 215 and the I-type clamping block 216 to rotate and change position, and the two sets of connecting electromagnetic blocks 215 switch the magnetic attraction to adjust the position and angle of the I-type clamping block 216. The alignment electric slide rail 217 drives the linkage processing frame 235 to move along the I-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, thereby achieving steady measurement and processing and ensuring the accuracy of the data.
