[0026] Working principle: When batch defect discrimination detection is carried out on the scraping plate body 5, a plurality of scraping plate bodies 5 are installed on the bottom side of the bent frame 39. Then, the second motor 25 is controlled to rotate, and the rotary stand 31 will move downward until the support bottom rod 37 is connected to the semi-circular groove 14. Then, the third motor 351 is controlled to rotate to move the rotary eccentric wheel 33 to the outside of the first telescopic rod 38. Then, the fourth motor 353 is controlled to rotate. Driven by the second tooth piece 352, the rotary eccentric wheel 33 will rotate 180 degrees. During the rotation process, the corresponding telescopic rod 38 will be pressed downward, and the scraping plate body 5 on the bottom side will be inserted into the fine sand layer. Then, the first motor 21 is controlled to rotate, and the first tooth piece 22 will drive the rotary seat 2 to rotate 180 degrees. During the rotation process, the scraping plate body 5 will scrape on the fine sand layer, and the scraping plate body 5 will leave contact imprints and movement trajectories on the fine sand layer. After rotating 180 degrees, according to the fine sand residue, imprints and movement trajectories on the fine sand layer, the damage degree of the scraping plate body 5 can be divided into three categories: First, there is almost no fine sand residue on the movement path, and the movement imprints are uniform and flat without unevenness. In this case, the scraping plate body 5 can still be used without further detection; Second, there are multiple traces of fine sand residue on the movement path, the residual sand amount is too much, and the imprints are wavy and uneven, showing unevenness. In this case, the scraping plate body 5 cannot be used without further detection; Third, there are multiple traces of fine sand residue on the movement path, the residual sand amount is small, and the unevenness of the sand marks is not obvious, making it difficult to visually distinguish, and further detection is required; Intuitively analyze the situation of the just-mentioned sand-marked silica gel, distinguish which situation the scraping plate body 5 belongs to, then control the reverse rotation of the rotating eccentric wheel 33 to restore to the initial state, retract the extended telescopic rod 38, then control the rotation of the second motor 25 to move the adjusting member 3 upward, and then control the rotating base 2 to rotate circumferentially multiple times again. The scraping plate 26 will restore the fine sand layer to be flat. After complete restoration, control the rotation of the third motor 351 to move the rotating eccentric wheel 33 to the position of the next telescopic rod 38, repeat the above operations, then distinguish the categories of the sand mark areas and record them, and then repeat the operations again to detect and distinguish the next scraping plate body 5 and record it.

[0029] A linkage rod 421 is also rotatably connected to the limit plate 41. A plurality of support plates 422 are fixedly installed on the outer surface of the linkage rod 421. Two inclined induction pressure rods 42 are installed on each of the support plates 422. The induction pressure rods 42 are parallel to the scraping plate body 5 to ensure that the contact rope 45 is connected to the scraping plate body 5. The induction pressure rods 42 are connected to the top surface of the contact rope 45, and their height positions are adapted to those of the scraping plate body 5. A driving gear is installed at one end of the linkage rod 421. A second air cylinder 423 is also installed on the limit plate 41. The output end of the second air cylinder 423 is provided with a movable toothed plate 424. The movable toothed plate 424 meshes with the driving gear to act on the angle rotation of the induction pressure rod 42. The induction pressure rod 42 is an induction rod when in contact. An array of thin film pressure sensors is arranged therein, which can detect the contact position between the contact rope 45 and it. The vibration characteristics of the contact rope 45 during the moving process are collected through an accelerometer.

[0030] Working principle: After the detections in Embodiment 1 are completed, control the second motor 25 to rotate, raise the adjusting member 3 to the specified height, and then control the rotating base 2 to rotate again. During the rotation, the rolling ball 361 will first be connected in the arc groove 121 to support the rotating gantry 31. At this time, control the first cylinder 341 to retract backward. When the helical gear 36 contacts the helical ring 122, they will mesh with each other, and the rotating gantry 31 will start to flip. During the flipping process, the spring block 343 will retract backward. When the rotating gantry 31 flips 180 degrees, it will be snapped into the tail rod 311 again. At this time, control the first cylinder 341 to extend so that its telescopic end is connected in the outer shell 342, and the positioning of the rotating gantry 31 is completed again. Then continue to rotate the rotating base 2 to move the rotating gantry 31 to the detection position under the bottom side of the rotation detection member 4; Then, according to the detection situation in Embodiment 1, test the scraping plate body 5 that needs further detection; Control the third motor 351 to rotate. The positioning screw rod 35 will move the rotating eccentric wheel 33 to the outside of the corresponding telescopic rod 38 at the corresponding position. Then control the fourth motor 353 to rotate, and push the corresponding telescopic rod 38 outwards. The corresponding scraping plate body 5 will extend upwards. After extending to the specified height, stop. Then control the fifth motor 43 to rotate. First, rotate the thickest contact rope 45 to the horizontal position on the right side. At this time, the convex block 453 at the end of the contact rope 45 will rotate between the moving blocks 464. Then control the sixth motor 471 to rotate. Under the rotation of the outer rotating rod 47, the displacement screw rod 463 will start to rotate. The moving block 464 drives the contact rope 45 to move to one end of the scraping plate body 5 and then stop. Then control the second cylinder 423 to retract upwards. During the upward movement of the movable tooth plate 424, it will drive the support plate 422 to flip, and the induction pressure rod 42 will press on the top surface of the contact rope 45. At this time, the induction pressure rod 42 will sense the contact position with the contact rope 45. At this time, the contact positions of all the induction pressure rods 42 and the contact rope 45 are on the same horizontal line. Then continue to control the sixth motor 471 to rotate, and the contact rope 45 will be movably connected to the scraping plate body 5. When moving to the defective area, if the opening at the defective part is larger than the diameter of the contact rope 45, when the contact rope 45 passes through, the contact rope 45 will sink into it. At this time, the two ends of the contact rope 45 are still moving at a constant speed. At this time, there is a large difference between the contact positions of the multiple induction pressure rods 42 and the contact rope 45. After the controller receives the signal with a large difference, it will stop the movement of the contact rope 45, and it is concluded that under the detection movement of the thickest contact rope 45, a defect with a larger diameter is detected on the scraping plate body 5 and it cannot be used anymore, and the size of the defect of the scraping plate body 5 is classified; If the opening at the defect is smaller than the diameter of the contact rope 45, when the contact rope 45 passes through, the contact rope 45 will get stuck. After getting stuck, it will quickly resume and continue with the subsequent detection. When getting stuck, the induction lever 42 will sense the vibration generated by the contact rope 45, and the signal will be sent back to the controller and recorded. Then, the position of this contact rope 45 will be restored to the rotary adjusting piece 44, and the fifth motor 43 will be controlled to rotate to switch to the next contact rope 45 with a slightly smaller diameter to detect the scraping plate body 5 again. The detection results are again divided into the above two situations: one is that the defect completely jams the contact rope 45 and it can no longer be used, and the other is that there is a jamming situation during the movement. Then, a slightly thinner contact rope 45 is replaced for testing; until all the contact ropes 45 with different thicknesses on the rotary adjusting piece 44 are detected once. If there is no jamming situation, it means that the scraping plate body 5 can still continue to be used. Then, the scraping plate bodies 5 jammed by the contact ropes 45 with different thicknesses are classified for subsequent unified maintenance and other operations; After the detection of the scraping plate body 5 on the rotary mounting table 31 is completed, control the rotary eccentric wheel 33 to resume, lower the scraping plate body 5, and then adjust the height of the adjusting member 3. After adjusting to the specified position, control the rotary seat 2 to rotate again. The helical gear 36 will contact the helical ring 122 on the other side. Repeat the above operation to rotate the rotary mounting table 31 by 180 degrees to restore it to its original position, and then disassemble the detected scraping plate body 5 and replace it with the next batch for testing again.
