b. according to the detection requirement, a second servo motor (35) of the lifting mechanism (3) works to drive the main gear (34) and the pinion (33) to rotate, so that a second wire wheel (32) on the main shaft (31) can receive and release a second rope (36), and the height position of the detector is adjusted;
c. meanwhile, when the detection instrument needs to be adjusted on two sides during detection, the first servo motors (24) on the two sides independently work to drive the first wire wheels (23) on the supporting shafts (22) to rotate, so that the first ropes (28) pull the rollers (25) to rotate, the frame (26) moves transversely, and the detection instrument is adjusted transversely.
