[0038] In a specific application scenario, when detecting the coating thickness of the building steel structure body 3, first place the building steel structure body 3 above the conveying belt 12, and convey the building steel structure body 3 through the conveying belt 12. During the conveying process, the upper laser detector 10 and the lower laser detector 11 located on the tool horizontal rod 802 detect the coating thickness on the upper and lower surfaces of the building steel structure body 3. At the same time, the electric drive rod 810 is started to drive the laser detector 835 on the detection frame 811 to move to the center position of the side edge of the building steel structure body 3. Then, the lead screw motor 808 is started, and the bidirectional lead screw 806 is rotated to drive the counter sliding seat 804 to move in opposite directions, so that the laser detector 835 on the detection frame 811 moves to the inside of the side edge of the building steel structure body 3. The reset spring 816 between the rotating shaft two 814 and the fixed circular frame 817 makes the laser detector 835 initially in a horizontal state. Then, the servo motor 824 is started, and the servo motor 824 drives the linkage gear 821 to rotate, so that the angle adjustment tooth plate one 822 on one of the linkage gears 821 drives the bidirectional adjustment gear 819 to rotate forward, so that the laser detector 835 on one side of the angle adjustment tool plate 825 on the rotating shaft two 814 rotates forward by ninety degrees. At this time, the reset spring 816 is compressed. The servo motor 824 is intermittently stopped. The angle adjustment tooth plate one 822 and the bidirectional adjustment gear 819 are not separated. At this time, the laser detector 835 detects the bottom surface of the side edge of the building steel structure body 3. After the detection is completed, the servo motor 824 is started. At this time, the angle adjustment tooth plate one 822 and the bidirectional adjustment gear 819 are separated. The reset spring 816 rebounds, so that the laser detector 835 is in the initial state. Subsequently, the angle adjustment tooth plate two 823 on the linkage gear 821 drives the bidirectional adjustment gear 819 to rotate reversely, so that the laser detector 835 on one side of the angle adjustment tool plate 825 on the rotating shaft two 814 rotates reversely by ninety degrees. At this time, the reset spring 816 is stretched. The servo motor 824 is intermittently stopped. The angle adjustment tooth plate two 823 and the bidirectional adjustment gear 819 are not separated. At this time, the laser detector 835 detects the upper surface of the side edge of the building steel structure body 3. After the detection is completed, the servo motor 824 is started. At this time, the angle adjustment tooth plate two 823 and the bidirectional adjustment gear 819 are separated. The reset spring 816 rebounds, so that the laser detector 835 is in the initial state. During the rotation of the angle adjustment tool plate 825, the stretching spring one 828 extrudes the extrusion roller 831, so that the anti-deviation block 833 makes the self-adaptive center seat 834 always in a horizontal state, avoiding deviation of the laser detector 835 from the building steel structure body 3 horizontally. Through the detection module 8, the thickness of the special-shaped building steel structure fireproof coating is detected, and the applicability of the detection device is improved.

[0039] Referring to Figure 1 , Figure 9 and Figure 10The detection auxiliary module 9 comprises a plurality of conveying limiting plates 906, and the conveying limiting plates 906 are located on both sides of the building steel structure body 3. The detection auxiliary module 9 is used for limiting and guiding the building steel structure body 3, so as to avoid the deviation of the moving track of the building steel structure body 3 in the conveying and detection process and affect the detection effect.

[0040] The detection auxiliary module 9 further comprises guide cylinders 901, and one end of the two guide cylinders 901 located on the same side is fixedly connected with a same horizontal moving plate 902. The side of the plurality of horizontal moving plates 902 is provided with two through holes, and the inside of the plurality of through holes is fixedly connected with guide round pipes 903.

[0041] Referring to Figure 1 , Figure 9 and Figure 10 , the inside of the plurality of guide round pipes 903 is slidably connected with telescopic columns 904, and the telescopic column 904 is fixedly connected with a same telescopic spring two 905 opposite to the guide round pipe 903. The telescopic spring two 905 is located outside the telescopic column 904, and the side of the telescopic column 904 is fixedly connected with the side of the conveying limiting plate 906.

[0042] Referring to Figure 1 , Figure 9 and Figure 10 , the side of the plurality of conveying limiting plates 906 is fixedly connected with two mounting horizontal plates 907, and the side of the plurality of mounting horizontal plates 907 is provided with a round hole seven. The inside of the opposite two round holes seven is connected with a same guide roller 908 through a bearing. The side of the two tool supporting plates 2 is fixedly connected with two electric telescopic rods 909, and the driving end of the electric telescopic rod 909 is fixedly connected with the side of the horizontal moving plate 902.

[0043] In a specific application scenario, when the building steel structure body 3 is conveyed and detected, the electric telescopic rod 909 is started, the electric telescopic rod 909 drives the horizontal moving plate 902 to move the conveying limiting plate 906 to both sides of the building steel structure body 3, so that the guide roller 908 on the conveying limiting plate 906 limits and guides the building steel structure body 3, so as to avoid the deviation of the moving track of the building steel structure body 3 in the conveying and detection process and affect the detection effect.

[0044] Referring to Figure 1 and Figure 3 , the side of one of the tool supporting plates 2 is fixedly connected with a mounting seat one 4, and the side of the mounting seat one 4 is fixedly connected with a driving motor 5. The driving end of the driving motor 5 is connected with one end of one of the rotating shafts 7 through a shaft coupling.

[0045] Working principle: when detecting the coating thickness of the building steel structure body 3, first place the building steel structure body 3 above the conveying belt 12, and convey the building steel structure body 3 through the conveying belt 12. When conveying, start the electric telescopic rod 909, and drive the horizontal moving plate 902 to move the conveying limiting plate 906 to both sides of the building steel structure body 3, so that the guide rollers 908 on the conveying limiting plate 906 limit and guide the building steel structure body 3. In the conveying process, the upper and lower laser detectors 10 and 11 on the tool horizontal rod 802 detect the coating thickness on the upper and lower surfaces of the building steel structure body 3, and at the same time, start the electric drive rod 810 to drive the laser detector 835 on the detection frame 811 to move to the center position of the side of the building steel structure body 3. Then start the lead screw motor 808, and drive the counter sliding seat 804 to move in opposite directions through the rotation of the bidirectional lead screw 806, so that the laser detector 835 on the detection frame 811 moves to the inside of the side of the building steel structure body 3. The reset spring 816 between the rotating shaft two 814 and the fixed circular frame 817 makes the laser detector 835 initially in a horizontal state. Then start the servo motor 824, and drive the linkage gear 821 to rotate through the servo motor 824, so that the laser detector 835 on one side of the angle adjustment tool plate 825 on the rotating shaft two 814 rotates ninety degrees, and the reset spring 816 is compressed at this time. At this time, stop the servo motor 824 intermittently, and the angle adjustment tooth plate one 822 and the bidirectional adjustment gear 819 are not separated. At this time, detect the bottom surface of the side of the building steel structure body 3 through the laser detector 835. After detection is completed, start the servo motor 824, and at this time, the angle adjustment tooth plate one 822 and the bidirectional adjustment gear 819 are separated, and the reset spring 816 rebounds to make the laser detector 835 in the initial state. Subsequently, the angle adjustment tooth plate two 823 on the linkage gear 821 drives the bidirectional adjustment gear 819 to reverse, so that the laser detector 835 on one side of the angle adjustment tool plate 825 on the rotating shaft two 814 reverses ninety degrees, and the reset spring 816 is stretched at this time. At this time, stop the servo motor 824 intermittently, and the angle adjustment tooth plate two 823 and the bidirectional adjustment gear 819 are not separated. At this time, detect the upper surface of the side of the building steel structure body 3 through the laser detector 835. After detection is completed, start the servo motor 824, and at this time, the angle adjustment tooth plate two 823 and the bidirectional adjustment gear 819 are separated, and the reset spring 816 rebounds to make the laser detector 835 in the initial state. In the rotating process of the angle adjustment tool plate 825, the stretching spring one 828 extrudes the extrusion roller 831, so that the anti-deviation block 833 makes the self-adaptive center seat 834 always in a horizontal state, avoiding deviation of the laser detector 835 from the building steel structure body 3 horizontally.
