Description

Technical Field

[0001] The utility model relates to the technical field of coating detection, in particular to a device for detecting the thickness of an anti-corrosion coating of a bridge component. Background Art

[0002] Coating is a solid continuous film obtained by applying the paint once. It is a thin layer of plastic applied to metal, fabric, plastic and other substrates for the purpose of protection, insulation, decoration, etc. The paint can be gaseous, liquid or solid. The type and state of the paint are usually determined by the substrate to be sprayed. After coating the plate, thickness testing is required to ensure its stability in use.

[0003] A coating thickness detection device is disclosed in a Chinese utility model patent with announcement number CN219244580U. Through a threaded rod, the threaded rod drives an extension plate connected to a fixed plate to squeeze a spring, so that the two extension plates drive a detector connected to a reciprocating screw A to be lifted, so that the detector contacts the coating surface of the object to be detected, and then the motor A drives the flat gear B to engage with the flat gear A, so that the flat gear A drives the reciprocating screw A to rotate, so that the mounting block drives the detector to make linear reciprocating motion in the horizontal direction on the reciprocating screw A under the limit of the fixed rod, and then the moving mechanism is used to achieve the technical effect of comprehensive coating thickness detection of the coating surface of the object to be detected with different heights.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the device is used to detect the coating thickness of bridge components, it is necessary to first place the detection body on the surface of the placement plate, and then conduct a full-scale detection of the detection body. However, the detection body is prone to displacement or tilt during the placement process, which affects the detection of the coating thickness. At the same time, some impurities are easily attached to the surface of the detection body, which affects the detection of the coating thickness. The surface of the detection body needs to be brushed before detection, which is very troublesome. Utility Model Content

The bottom of the sliding plate is fixedly connected to the top of the extrusion rod 17, which is convenient for the lifting plate 5 to move forward and backward. The lifting plate 5 is installed inside with two gears 15 meshing with the toothed plate 4. The lifting plate 5 is a hollow plate, and grooves for the toothed plate 4 to pass through are provided on both sides of the lifting plate 5, which is convenient for the toothed plate 4 to drive the gear 15 to rotate. The bottom end of the intermediate shaft of the gear 15 is fixedly connected with a brush sweeping member 14, and the brush sweeping member 14 includes a cross plate, and the bottom of the cross plate is fixedly connected with bristles at equal intervals, which is convenient for cleaning impurities attached to the surface of the detection body 8. The bottom of the lifting plate 5 is fixedly connected with a detector 13 through a long rod.

[0029] The correction component is used to automatically correct the detection body 8 so that the horizontal direction of the detection body 8 is consistent with the horizontal direction of the placement plate 1. The correction component includes two symmetrical mounting plates 7 fixedly connected to the top of the placement plate 1, and extrusion pieces 9 are installed at equal intervals inside the mounting plate 7.

[0030] The implementation principle of a bridge component anti-corrosion coating thickness detection device in the embodiment of the present application is as follows: after the detection body 8 is placed on the placement plate 1, the small screw 19 is rotated according to the distance from the detector 13 and the brush sweeping member 14 to the top of the detection body 8 and the distance from the abutment plate 10 to the detection body 8. The small screw 19 drives the pressure block 18 to move in the vertical direction, so that the distance from the extrusion rod 17 to the pressure block 18 changes. In the process that the brush sweeping member 14 gradually abuts against the top of the detection body 8, the extrusion rod 17 drives the pressure block 18 to descend, so that the mounting frame 11 drives the pressure plate 16 to descend. The pressure plate 16 descends, so that the piston rod at the top of the extrusion member 9 moves downward, and the air inside the extrusion member 9 pushes the piston rod at the bottom, and moves toward the detection body 8 against the abutment plate 10 until the abutment plate 10 abuts against the surface of the detection body 8, thereby realizing the automatic correction of the detection body 8 by the electric telescopic rod in the process of controlling the descent of the lifting plate 5, which facilitates the subsequent all-round detection of the detection body 8.

[0031] After the height adjustment is completed, start motor A, which drives screw A to rotate, so that the moving block and the slider move forward and backward, so that screw B6 drives the detector 13 to move forward and backward through the moving seat 3, which facilitates the adjustment of the front and rear positions of the detector 13. After adjusting the front and rear positions of the detector 13, start motor B, and motor B drives the moving seat 3 to move left and right through screw B6. In the process of moving left and right, the two gears 15 in the lifting plate 5 are acted upon by the toothed plate 4, driving the brush sweeper 14 to rotate, thereby sweeping away impurities attached to the surface of the detection body 8, avoiding the influence of impurities on the detection results of the coating thickness, and providing the accuracy of the detection results.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
