Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion coating detection, and particularly relates to an anti-corrosion coating detection device for steel structures. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are prone to corrosion. Generally, steel structures need to be derusted, galvanized or painted, and need to be maintained regularly. In order to ensure the uniformity of the coating thickness of the anti-corrosion coating layer, an anti-corrosion coating thickness detection device for steel structures is usually required to detect the thickness of the anti-corrosion coating layer, and then add anti-corrosion coating in time at places where the anti-corrosion coating is less.

[0003] At present, in the steel structure detection project, the detection of the anti-corrosion coating thickness is a very important detection item. According to the relevant industry standards, the requirement for measuring points is to detect five points for each component, and the value of each point is the average of the dry film thicknesses of three measuring points 50 mm apart. However, this method, on the one hand, cannot accurately measure the specific thickness situation, and at the same time, the detection is not convenient enough, and frequent detections are required, which reduces the detection efficiency and brings certain adverse effects to the use process.

[0026] Embodiment 2, as Figures 1 - 5 and Figure 7 shown, an anti-corrosion coating detection device for a steel structure. The adjusting device 3 includes a moving motor 31 and a meter counter 36. The output end of the moving motor 31 is fixedly installed with an advancing and retreating screw 32. A moving block 33 is threadedly installed on the outer surface of the advancing and retreating screw 32. The top of the moving block 33 is fixedly installed with a moving base 34. The top of the moving base 34 is fixedly installed with a fixed box 35. Side boxes 38 are fixedly installed on both sides of the fixed box 35. Lifting grooves 311 are formed at both ends on the side where the two side boxes 38 face each other. An elevating motor 39 is fixedly installed at the upper end inside the side box 38. The output end of the elevating motor 39 is fixedly installed with an elevating screw 310. The elevating screw 310 is rotatably installed inside the side box 38. A moving box 41 is movably installed between the two side boxes 38 at both ends. An elevating frame 42 is threadedly installed on the outer surface of the elevating screw 310. The elevating frame 42 is movably sleeved inside the lifting grooves 311.

[0027] Among them, the moving motor 31 is fixedly installed at one end of the top of the detection box 21, the advancing and retreating screw rod 32 is rotatably installed at the upper end inside the detection box 21, the moving block 33 is slidably installed inside the sliding groove 24, the moving base 34 is slidably installed on the outer surface of the fixed track 23, a bracket is fixedly installed on the right side of the fixed box 35, and a counter 36 is fixedly installed inside the bracket. The output end of the counter 36 is fixedly installed with a rubber single wheel 37. Both the rubber single wheel 37 and the rubber pad 15 are made of rubber, which increases the friction between the two and improves the accuracy of detecting the moving distance of the moving body 2. The lifting motor 39 controls the rotation of the lifting screw rod 310, and then the lifting frame 42 is lifted and lowered inside the fixed box 35, so that the ball 417 moves up and down through the lifting of the lifting frame 42, facilitating the detection of different positions of the steel structure.

[0028] Embodiment 3, as Figures 1 - 7 shown, for an anti-corrosion coating detection device for a steel structure, cavities are opened on both sides inside the moving box 41. Ink boxes 401 are fixedly installed on the right sides of the cavities on both sides of the moving box 41. Absorbent cotton 402 is placed inside the ink boxes 401. An activity groove is opened at the upper end on the right side of the ink box 401. Fixed frames 403 are fixedly installed at both ends on the right side of the moving box 41. Connecting ropes 46 are fixedly connected to both ends at the bottom on the right side of the moving box 41. One end of the connecting rope 46 is fixedly connected to a sleeve cover 47, and the sleeve cover 47 is sleeved on the outer surface of the fixed frame 403.

[0029] As Figure 6 shown, seals 404 are movably sleeved inside both ends on the right side of the moving box 41. Fixed racks 405 are fixedly installed at the bottoms of the seals 404. Telescopic motors 406 are fixedly installed at both ends on the right side of the moving box 41. The output ends of the telescopic motors 406 are fixedly installed with driving gears 408. The driving gears 408 are rotatably installed inside the moving box 41. The outer surfaces of the driving gears 408 are meshed with the tops of the fixed racks 405.

[0030] Among them, absorbent strips 407 are fixedly installed at the upper ends on the left side of the seals 404. The absorbent strips 407 are inserted and installed inside the activity grooves at the upper ends on the right side of the ink boxes 401. Ink is filled inside both ink boxes 401, and the colors of the ink inside both ink boxes 401 are different. The seals 404 at both ends are of different patterns, and the pattern can be an arrow. The arrow indicates the position with uneven thickness, facilitating the operator to quickly identify the position where the coating thickness of the steel material changes.

[0031] Since the absorbent strip 407 is a hydrophilic material, when the absorbent strip 407 is inserted inside the absorbent cotton 402, the seal 404 is kept in a wet state through the inside of the absorbent strip 407, facilitating the marking of the steel material. It should be noted that the present invention is an anti-corrosion coating detection device for steel structures. When in use, the steel material is placed on the top of the table board 14, with one end of the steel material leaning against the side of the positioning bar 16. By rotating the rotating handle 110, the position of the side positioning plate 19 is adjusted so that the side of the steel material is closely attached to the side of the side positioning plate 19. The cover 47 is opened to expose the seals 404 at both ends of the moving box 41. The moving motor 31 controls the rotation of the advancing and retreating screw 32, and the moving base 34 approaches the steel material on the top of the fixed track 23. The ball 417 presses against the side of the steel material, compressing the movable spring 411. The moving frame 413 moves to the left inside the moving slot 49. When the photoelectric sensor receiver 415 moves to the bottom of the photoelectric sensor transmitter 45, the photoelectric sensor transmitter 45 controls the moving motor 31 and the advancing and retreating screw 32 to stop rotating through an electrical signal, and the moving base 34 stops moving. At this time, the distance measuring sensor 412 detects that the distance to the marking plate 414 is zero, and the movable spring 411 is in a semi-compressed state. The rubber single wheel 37 is closely attached to the side of the rubber pad 15; The electric slide rail 12 controls the connecting block 25 to move from one side to the other side on the side of the support base 11. The ball 417 moves on the surface of the steel structure. When the thickness of the coating is relatively thin, due to the reaction force of the movable spring 411, the marking plate 414 moves to the right inside the moving slot 49, and the distance detected by the distance measuring sensor 412 increases. When the set distance is reached, the distance measuring sensor 412 controls the driving gear 408 to rotate through an electrical signal by the telescopic motor 406 at the right end. The seal 404 at the right end extends out inside the moving box 41, so that the seal 404 at the right end presses against the side of the steel structure to mark the steel structure. When the thickness of the encountered coating is relatively thick, the movable spring 411 will continue to compress, and the distance measuring sensor 412 detects that the distance to the marking plate 414 decreases. At this time, the telescopic motor 406 at the left end controls the driving gear 408 to rotate, and the seal 404 at the left end extends out inside the moving box 41, so that the seal 404 at the left end presses against the side of the steel structure to mark the steel structure, and by the different ink colors on the left and right sides, it is judged whether the anti-corrosion coating of the steel structure at this place is relatively thin or thick; While the detection box 21 moves on the side of the support base 11, the fixed rod 416 moves and expands and contracts along with the side of the steel structure. The distance measuring sensor 412 detects the change in the distance from the marking plate 414 and stores the changed data, and uses the counter 36 and the rubber single wheel 37 to detect and store the information on the moving distance of the fixed rod 416. The operator directly judges the position of the steel structure and the thickness of the anti-corrosion coating at this position according to the moving distance of the fixed rod 416, making the detection of the steel structure more comprehensive.

[0032] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
