[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 conveyor belt 12, and convey the building steel structure body 3 through the conveyor belt 12. During the conveying process, detect the coating thickness of the upper and lower surfaces of the building steel structure body 3 by the upper laser detector 10 and the lower laser detector 11 located on the tooling cross bar 802. 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 opposing slide seats 804 to move towards each other by 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 second rotating shaft 814 and the fixed circular frame 817 makes the laser detector 835 in a horizontal state initially. Then start the servo motor 824, and the servo motor 824 drives the linkage gear 821 to rotate. Thus, the angle adjustment tooth plate 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 tooling plate 825 on the second rotating shaft 814 rotates forward by ninety degrees. At this time, the reset spring 816 is compressed. Intermittently stop the servo motor 824 at this time, and the angle adjustment tooth plate 822 and the bidirectional adjustment gear 819 have not separated yet. At this time, detect the side bottom surface of the building steel structure body 3 by the laser detector 835. After the detection is completed, start the servo motor 824. At this time, the angle adjustment tooth plate 822 and the bidirectional adjustment gear 819 separate, and the reset spring 816 rebounds, making the laser detector 835 return to the initial state. Subsequently, the angle adjustment tooth plate 823 on the linkage gear 821 drives the bidirectional adjustment gear 819 to rotate in reverse, so that the laser detector 835 on one side of the angle adjustment tooling plate 825 on the second rotating shaft 814 rotates in reverse by ninety degrees. At this time, the reset spring 816 is stretched. Intermittently stop the servo motor 824 at this time, and the angle adjustment tooth plate 823 and the bidirectional adjustment gear 819 have not separated yet. At this time, detect the side upper surface of the building steel structure body 3 by the laser detector 835. After the detection is completed, start the servo motor 824. At this time, the angle adjustment tooth plate 823 and the bidirectional adjustment gear 819 separate, and the reset spring 816 rebounds, making the laser detector 835 return to the initial state. During the rotation of the angle adjustment tooling plate 825, the extrusion roller 831 is extruded through the first telescopic spring 828, so that the anti-deviation block 833 makes the adaptive center seat 834 always in a horizontal state, avoiding the horizontal deviation of the laser detector 835 from the building steel structure body 3. Through the detection module 8, it is beneficial to detect the thickness of the fireproof coating of the special-shaped building steel structure and improve the applicability of the detection device.

[0039] Refer to Figure 1 、 Figure 9 and Figure 10, the detection auxiliary module 9 includes a plurality of conveying limit plates 906, and the conveying limit plates 906 are located on both sides of the building steel structure body 3. The detection auxiliary module 9 is used to limit and guide the building steel structure body 3 to prevent the movement track of the building steel structure body 3 from shifting during the conveying and detection process, which affects the detection effect;

[0040] The detection auxiliary module 9 further includes a guiding cylinder 901. One end of two guiding cylinders 901 located on the same side is fixedly connected to the same horizontal moving plate 902. Two through holes are opened on one side of the plurality of horizontal moving plates 902, and guiding circular tubes 903 are fixedly connected inside the plurality of through holes.

[0041] Refer to Figure 1 , Figure 9 and Figure 10 , a telescopic column 904 is slidably connected inside the plurality of guiding circular tubes 903, and a same second telescopic spring 905 is fixedly connected to the opposite sides of the telescopic column 904 and the guiding circular tube 903. The second telescopic spring 905 is located outside the telescopic column 904, and one side of the telescopic column 904 is fixedly connected to one side of the conveying limit plate 906.

[0042] Refer to Figure 1 , Figure 9 and Figure 10 , two mounting cross plates 907 are fixedly connected to one side of the plurality of conveying limit plates 906, and circular holes seven are opened on one side of the plurality of mounting cross plates 907. A same guiding roller 908 is connected through bearings inside the opposite two circular holes seven. Two electric telescopic rods 909 are fixedly connected to one side of the two tooling support plates 2, and the driving end of the electric telescopic rod 909 is fixedly connected to one side of the horizontal moving plate 902.

[0043] In a specific application scenario, when the building steel structure body 3 is being conveyed and detected, by starting the electric telescopic rod 909, the electric telescopic rod 909 drives the horizontal moving plate 902 to move the conveying limit plate 906 towards both sides of the building steel structure body 3, so that the guiding roller 908 on the conveying limit plate 906 limits and guides the building steel structure body 3 to prevent the movement track of the building steel structure body 3 from shifting during the conveying and detection process, which affects the detection effect.

[0044] Refer to Figure 1 and Figure 3 , a first mounting seat 4 is fixedly connected to one side of one of the tooling support plates 2, and a driving motor 5 is fixedly connected to one side of the first mounting seat 4. The driving end of the driving motor 5 is connected to one end of one of the rotating shafts 7 through a 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 conveyor belt 12, and convey the building steel structure body 3 through the conveyor belt 12. During the conveying process, start the electric telescopic rod 909, and the electric telescopic rod 909 drives the horizontal moving plate 902 to move the conveying limiting plate 906 towards 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. During the conveying process, detect the coating thickness of the upper and lower surfaces of the building steel structure body 3 through the upper laser detector 10 and the lower laser detector 11 located on the tooling cross bar 802. 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 the rotation of the bidirectional lead screw 806 drives the opposing sliding seats 804 to move towards each other, 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 second rotating shaft 814 and the fixed circular frame 817 makes the laser detector 835 in a horizontal state initially. Then start the servo motor 824, and the servo motor 824 drives the linkage gear 821 to rotate. Thus, the angle adjustment tooth plate 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 tooling plate 825 on the second rotating shaft 814 rotates forward by 90 degrees. At this time, the reset spring 816 is compressed. Intermittently stop the servo motor 824 at this time, and the angle adjustment tooth plate 822 and the bidirectional adjustment gear 819 have not separated yet. At this time, detect the side bottom surface of the building steel structure body 3 through the laser detector 835. After the detection is completed, start the servo motor 824. At this time, the angle adjustment tooth plate 822 and the bidirectional adjustment gear 819 separate, and the reset spring 816 rebounds, making the laser detector 835 return to the initial state. Subsequently, the angle adjustment tooth plate 823 on the linkage gear 821 drives the bidirectional adjustment gear 819 to rotate in reverse, so that the laser detector 835 on one side of the angle adjustment tooling plate 825 on the second rotating shaft 814 rotates in reverse by 90 degrees. At this time, the reset spring 816 is stretched. Intermittently stop the servo motor 824 at this time, and the angle adjustment tooth plate 823 and the bidirectional adjustment gear 819 have not separated yet. At this time, detect the side upper surface of the building steel structure body 3 through the laser detector 835. After the detection is completed, start the servo motor 824. At this time, the angle adjustment tooth plate 823 and the bidirectional adjustment gear 819 separate, and the reset spring 816 rebounds, making the laser detector 835 return to the initial state. During the rotation of the angle adjustment tooling plate 825, the extrusion roller 831 is extruded through the first telescopic spring 828, so that the anti-deviation block 833 makes the adaptive center seat 834 always in a horizontal state, avoiding the horizontal deviation of the laser detector 835 from the building steel structure body 3.
