Technical Field

[0001] The utility model relates to a coating thickness detector, in particular to an adjustable fire retardant coating thickness detector for steel structure buildings. Background Art

[0002] Fire retardant coatings for steel structures are functional coatings specifically designed to improve the fire resistance of steel structures. They form a thermally insulating protective layer on the surface of the steel structure, slowing the temperature rise of the steel under high-temperature fire conditions, thereby increasing the building's fire resistance and allowing for more time for rescue and evacuation.

[0003] Ordinary detectors are only used to measure thickness and cannot handle defects such as rough, uneven or partial peeling of the coating surface found during the detection process. Additional grinding or repair equipment is required for use. Therefore, an adjustable steel structure building fire retardant coating thickness detector is urgently needed.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0026] The cross frame 5 is connected with the slide 6 through an interlaced connection, and a support frame 9 is fixedly provided on one side of the bottom end of the slide 6, and a turntable 10 is rotatably provided on one side of the support frame 9, and a double-headed bracket 11 is fixed on one side of the turntable 10, and one end of the two double-headed brackets 11 is fixed with a sleeve 12, and the inner walls of the two sleeves 12 are fixed with electric telescopic rods 13, and the telescopic end of one of the electric telescopic rods 13 is fixed with a U-shaped frame 14, and the two sides of the inner wall of the U-shaped frame 14 are rotatably connected to the two ends of the grinding wheel 15, and the telescopic end of the other electric telescopic rod 13 is fixedly connected to the top of the ultrasonic detector 16.

[0027] Specifically, a driving motor 8 is fixedly provided on the other side of the support frame 9 , and an output end of the driving motor 8 passes through the support frame 9 and is fixedly connected to the other side of the turntable 10 .

[0028] Specifically, fixing columns 2 are inserted on both sides of the top of the two fixing frames 1, connecting columns 3 are fixed to the bottom ends of the four fixing columns 2, and suction cups 4 are fixed to the bottom ends of the four connecting columns 3.

[0029] Specifically, one side of the two fixing frames 1 is fixedly connected to the two ends of the lead screw 17 near the horizontal frame 5, and the outer wall of the lead screw 17 is threadedly connected to the slide 6. An organic groove is opened at the top of one of the fixing frames 1, and a servo motor 7 is fixed inside the organic groove. The output end of the servo motor 7 is fixedly connected to one end of the lead screw 17.

[0030] Specifically, a switch panel is fixed on one side of one of the fixing frames 1, and a drive motor switch, a servo motor switch and an electric telescopic rod switch are fixed on the surface of the switch panel respectively.

The drive motor 8 is started to drive the turntable 10 on the support frame 9 to rotate, and the angle of the double-head bracket 11 is adjusted so that the grinding wheel 15 and the ultrasonic detector 16 are in the optimal detection and grinding position. The electric telescopic rod 13 is controlled so that its telescopic end drives the U-shaped frame 14 and the grinding wheel 15 to fit the coating surface.
