Description

Technical Field

[0001] This invention relates to the field of anti-corrosion coating testing technology, and in particular to an anti-corrosion coating testing device for steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of steel profiles and plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components are usually connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. To ensure the uniformity of the anti-corrosion coating thickness, a steel structure anti-corrosion coating thickness detection device is usually used to detect the thickness of the anti-corrosion coating layer, and then promptly add anti-corrosion coating to areas with insufficient coating.

[0003] Currently, in steel structure inspection projects, the thickness detection of anti-corrosion coatings is a very important inspection item. According to relevant industry standards, the requirement is to test five points for each component, and the value of each point is the average of the dry film thickness of the coating at three test points 50mm apart. However, this method cannot accurately measure the specific thickness, and it is not convenient enough, requiring frequent testing, which reduces the inspection efficiency and has certain adverse effects on the user experience. In order to overcome the shortcomings of existing technologies, we propose an anti-corrosion coating detection device for steel structures. Summary of the Invention

The distance sensor detects the change in distance from the marking plate and stores the data. A meter counter and a rubber wheel are used to detect and store the information on the distance the fixed rod moves. Based on the distance the fixed rod moves, the operator can directly determine the position of the steel structure and the thickness of the anti-corrosion coating at that position, making the steel structure inspection more comprehensive and providing a more intuitive understanding of the position and changes in the thickness of the anti-corrosion coating.

[0019] 2. In this invention, the lifting motor controls the rotation of the lifting screw, thereby causing the lifting frame to rise and fall inside the fixed box.

[0020] 3. By setting up a movable box and stamps, the stamps at both ends can mark the steel structure according to the thickness of the anti-corrosion coating. The stamps at the left or right end can mark whether the anti-corrosion coating of the steel structure is thin or thick, and the different ink colors on the left and right sides can indicate whether the anti-corrosion coating of the steel structure is thin or thick. This allows operators to see the thickness of the steel structure coating more intuitively, which is convenient for subsequent operations. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1, as Figures 1-5 and Figure 7 As shown, a steel structure anti-corrosion coating testing device includes a workbench 1, a movable body 2, an adjustment device 3, and a testing component 4. The movable body 2 is slidably mounted on the side of the workbench 1, and the adjustment device 3 is slidably mounted on the top of the movable body 2. The top of the adjustment device 3 is fixedly connected to the testing component 4.

[0031] like Figure 4As shown, the detection component 4 includes a movable box 41, a photoelectric sensor transmitter 45, and a photoelectric sensor receiver 415. Lifting frames 42 are fixedly installed on both sides of the bottom of the movable box 41. Sliding chambers 43 are fixedly installed on both sides of the top of the movable box 41. A top frame 44 is fixedly installed on the top of the two sliding chambers 43. The photoelectric sensor transmitter 45 is fixedly installed inside the top frame 44. A movable groove 49 is opened on the top of the movable box 41, located between the two sliding chambers 43. The photoelectric sensor transmitter 45 is located in the middle of the sliding chamber 43. A movable frame 413 is slidably installed inside the movable groove 49. The top of the movable frame 413 is fixedly installed with the photoelectric sensor receiver 415. A fixing rod 416 is fixedly installed on the right side of the movable frame 413. A ball bearing 417 is rotatably installed on the right end of the fixing rod 416. Limiting rods 410 are fixedly installed inside the two sliding chambers 43. A movable spring 411 is movably sleeved on the outer surface of the limiting rod 410. A ranging sensor 412 is fixedly installed on the left side inside the movable groove 49.

[0032] like Figure 5 As shown, the lower end of the movable frame 413 is slidably installed inside the movable groove 49. A marking plate 414 is fixedly installed on the left side of the lower end of the movable frame 413. The two sides of the top of the movable frame 413 are slidably installed inside the two sliding chambers 43. The movable frame 413 is movably sleeved on the outer surface of the limiting rod 410. The movable spring 411 is located between the inner wall of the sliding chamber 43 and the movable frame 413. The fixed rod 416 is movably sleeved on the right side of the movable box 41. The distance to the marking plate 414 is detected by the distance sensor 412. During the movement of the fixed rod 416, the change in the thickness of the anti-corrosion coating of the steel structure is determined by the movement distance of the movable frame 413 inside the movable groove 49.

[0033] like Figure 2 As shown, the mobile body 2 includes a detection box 21. An operation panel 22 is fixedly installed on the left side of the detection box 21. A sliding groove 24 is provided on the top of the detection box 21. Fixed rails 23 are fixedly installed on both sides of the top of the detection box 21. The fixed rails 23 are located on both sides of the sliding groove 24. A connecting block 25 is fixedly installed on the side of the detection box 21. Limit sleeves 26 are fixedly installed at both the upper and lower ends of the side of the detection box 21.

[0034] like Figure 7As shown, the workbench 1 includes a support base 11, a positioning strip 16, and a side positioning plate 19. An electric slide rail 12 is fixedly installed on the side of the support base 11. Track rods 13 are fixedly installed at both the upper and lower ends of the side of the support base 11. A table plate 14 is fixedly installed on the top of the support base 11. Rubber pads 15 are fixedly installed on the side of the table plate 14. One end of the top of the table plate 14 is fixedly connected to the positioning strip 16. A support plate 17 is fixedly installed on the side of the top of the table plate 14 away from the moving body 2. Multiple rotating screws 18 are threaded onto the internal parts of the support plate 17. One end of each of the 8 is fixedly equipped with a rotating handle 110, and the other end of each of the multiple rotating screws 18 is rotatably connected to the side positioning plate 19. The top of the platform 14 is provided with multiple limiting grooves 111, and the bottom of the side positioning plate 19 is slidably installed inside the limiting grooves 111. By rotating the rotating handle 110, the side positioning plate 19 is moved on the top of the platform 14. According to the width of the steel structure, the side of the steel structure is positioned, and the positioning strip 16 is used to mark one end of the steel structure to prevent the steel structure from shifting during the inspection process, which facilitates the inspection of one side of the steel structure.

[0035] The connecting block 25 is slidably installed on the outer surface of the electric slide rail 12, and the limiting sleeve 26 is movably sleeved on the outer surface of the track rod 13. The moving body 2 moves on the side of the support base 11 through the electric slide rail 12, so that the fixed rod 416 can detect the side of the steel structure throughout the detection process, making the detection position more comprehensive and able to completely detect the change in the thickness of the anti-corrosion coating.

[0036] Example 2, as Figures 1-5 and Figure 7 As shown, a steel structure anti-corrosion coating detection device includes an adjustment device 3 comprising a moving motor 31 and a meter counter 36. A forward / backward screw 32 is fixedly installed at the output end of the moving motor 31. A moving block 33 is threaded onto the outer surface of the forward / backward screw 32. A moving base 34 is fixedly installed on the top of the moving block 33. A fixed box 35 is fixedly installed on the top of the moving base 34. Side boxes 38 are fixedly installed on both sides of the fixed box 35. Lifting grooves 311 are opened at both ends of the two side boxes 38 facing each other. A lifting motor 39 is fixedly installed at the upper end inside the side box 38. A lifting screw 310 is fixedly installed at the output end of the lifting motor 39. The lifting screw 310 is rotatably installed inside the side box 38. A moving box 41 is movably installed between the two side boxes 38. A lifting frame 42 is threaded onto the outer surface of the lifting screw 310 and movably sleeved inside the lifting groove 311.

[0037] The mobile motor 31 is fixedly installed at one end of the top of the detection box 21. The forward and backward screw 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 the inside of the bracket is fixedly installed with the meter counter 36. A rubber single wheel 37 is fixedly installed at the output end of the meter counter 36. 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 the moving distance detection of the mobile body 2. The lifting motor 39 controls the lifting screw 310 to rotate, thereby causing the lifting frame 42 to rise and fall inside the fixed box 35. The ball 417 moves up and down through the lifting frame 42, which facilitates the detection of different positions of the steel structure.

[0038] Example 3, as Figures 1-7 As shown, a steel structure anti-corrosion coating testing device has cavities on both sides inside the movable box 41. An ink tank 401 is fixedly installed on the right side of the cavities on both sides of the movable box 41. An absorbent cotton 402 is placed inside the ink tank 401. An movable groove is opened at the upper end of the right side of the ink tank 401. A fixed frame 403 is fixedly installed at both ends of the right side of the movable box 41. A connecting rope 46 is fixedly connected to both ends of the bottom right side of the movable box 41. A cover 47 is fixedly connected to one end of the connecting rope 46. The cover 47 is fitted onto the outer surface of the fixed frame 403.

[0039] like Figure 6 As shown, stamps 404 are movably fitted inside both ends of the right side of the mobile box 41. A fixed rack 405 is fixedly installed at the bottom of the stamp 404. Telescopic motors 406 are fixedly installed at both ends of the right side of the mobile box 41. A drive gear 408 is fixedly installed at the output end of the telescopic motor 406. The drive gear 408 is rotatably installed inside the mobile box 41. The outer surface of the drive gear 408 meshes with the top of the fixed rack 405.

[0040] The upper left side of the stamp 404 is fixedly equipped with a water-absorbing strip 407, which is inserted into the movable groove at the upper right side of the ink tank 401. Both ink tanks 401 are filled with ink, and the ink colors inside the two ink tanks 401 are different. The stamps 404 at both ends have different patterns, such as arrows, which indicate the location of uneven thickness, making it easy for operators to quickly identify the location of changes in the thickness of the steel coating.

[0041] Because the absorbent strip 407 is made of hydrophilic material, when the absorbent strip 407 is inserted into the absorbent cotton 402, the seal 404 remains moist through the interior of the absorbent strip 407, making it easier to mark steel materials.

[0042] It should be noted that this invention is a steel structure anti-corrosion coating testing device. In use, the steel material is placed on top of the platform 14, with one end of the steel material resting against the side of the positioning strip 16. By rotating the handle 110, the position of the side positioning plate 19 is adjusted so that the side of the steel material is tightly against the side of the side positioning plate 19. The cover 47 is opened, exposing the stamps 404 at both ends of the moving box 41. The moving motor 31 controls the forward and backward screw 32 to rotate, and the moving base 34 moves closer to the steel material on top of the fixed track 23. The ball bearings 417... Pressing down on the side of the steel material compresses the movable spring 411, and the moving frame 413 moves to the left inside the moving groove 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 forward and backward screw 32 to stop rotating through the electrical signal, and the moving base 34 stops moving. At this time, the distance sensor 412 detects that the distance of the marker plate 414 is zero, the movable spring 411 is in a semi-compressed state, and the rubber single wheel 37 is in close contact with the side of the rubber pad 15.

[0043] The electric slide rail 12 controls the connecting block 25 to move from one side to the other on the side of the support base 11. The ball bearing 417 moves on the surface of the steel structure. When it encounters a thin coating, the reaction force of the movable spring 411 causes the marking plate 414 to move to the right inside the moving groove 49. The distance detected by the distance measuring sensor 412 increases. When the set distance is reached, the distance measuring sensor 412 uses an electrical signal to cause the telescopic motor 406 at the right end to control the drive gear 408 to rotate. The stamp 404 at the right end extends out inside the moving box 41, making... The stamp 404 on the right end presses against the side of the steel structure to mark it. When the coating thickness is thick, the movable spring 411 will continue to compress, and the distance sensor 412 will detect the decrease in the distance of the marking plate 414. At this time, the telescopic motor 406 on the left end controls the drive gear 408 to rotate, and the stamp 404 on the left end extends out of the moving box 41, so that the stamp 404 on the left end presses against the side of the steel structure to mark it. The difference in ink color between the left and right sides can be used to determine whether the anti-corrosion coating of the steel structure at that location is thin or thick.

[0044] While the inspection box 21 moves along the side of the support base 11, the fixing rod 416 moves and extends along the side of the steel structure. The distance sensor 412 detects the change in distance from the marking plate 414 and stores the data. The meter counter 36 and the rubber wheel 37 are used to detect and store the information of the moving distance of the fixing rod 416. Based on the moving distance of the fixing rod 416, the operator can directly determine the position of the steel structure and the thickness of the anti-corrosion coating at that position, making the inspection of the steel structure more comprehensive.

[0045] 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 to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
