In order to ensure the normal progress of subsequent test operations, the operator needs to manually clean the paint film. The operation is cumbersome and manpower-consuming, and the test device needs to be shut down for a long time to complete the cleaning operation, which has a great impact on the continuous testing efficiency of the test device.

[0021] The present invention also discloses a method for testing the drying time of a steel bar preservative for autoclaved aerated concrete, which is implemented using the above-mentioned steel bar preservative drying time testing device. The method specifically comprises the following steps:

[0022] S1. Apply the preservative to be tested in the positioning groove to form a paint film, then place the qualitative filter paper on the top of the paint film, close the sealing door and energize the heating resistor inside the shell, so that the temperature inside the shell rises to a preset temperature;

[0023] S2, when the hydraulic cylinder rotates, it drives the lifting frame A to move downward, when the lifting frame A moves downward, it drives the lifting frame B to move downward through the reset spring A, drives the guide pressure rod to move downward through the extension plate, when the lifting frame B moves downward, it drives the drying tester to move downward through the end plate;

[0024] S3. As the drying tester continues to move downward, the drying tester is pressed on the top of the qualitative filter paper, and the end plate is pressed on the top of the two L-shaped support plates. At this time, due to the obstruction of the L-shaped support plates, the end plate and the drying tester cannot continue to move downward. Subsequently, as the lifting frame A continues to move downward, the reset spring A is compressed, and the lifting frame A continues to drive the guide pressure rod to move downward through the extension plate;

[0025] S4. The bottom end of the guide pressure rod is attached to the top of the lifting block. The lifting block then moves down synchronously along the guide column and compresses the reset spring B during the downward movement. When the lifting block moves down, the metal plate is driven to move down synchronously through the rotating shaft. When the metal plate moves down, the qualitative filter paper is driven to detach from the bottom of the drying tester.

[0026] S5. The gear is driven by the rotating shaft to mesh with the adjacent rack. Subsequently, as the rotating shaft continues to move downward, the rack drives the gear to rotate. When the gear rotates, the metal plate is driven to rotate through the rotating shaft. During the rotation of the rotating shaft, the plurality of first magnets are driven to rotate through the fixed collar. The plurality of first magnets are repeatedly demagnetized and re-magnetized with the plurality of second magnets in succession.

[0027] S6, the gear and the rack stop meshing and disengage, and the metal plate is flipped over. If the paint film has dried within the preset time, the qualitative filter paper falls on the top of the guide plate during the flipping of the metal plate and is output to the inside of the collection tray. If the paint film has not dried within the preset time, the qualitative filter paper adheres to the bottom of the paint film and cannot fall.

[0028] S7, the continuously rotating grinding wheel is driven by the second motor to enter the inner side of the positioning groove, and the continuously rotating grinding wheel removes the tested paint film and the qualitative filter paper that has not fallen inside the positioning groove;

[0029] S8. After the paint film on the inner side of the positioning groove is cleaned, the hydraulic cylinder drives the lifting frame A to move upward and reset. During the upward movement of the lifting frame A, the preservative bearing mechanism and the testing mechanism are reset synchronously;

[0030] S9. After the lifting frame A reaches the initial position, the hydraulic cylinder stops running and then the sealing door is opened.

[0031] Technical effects and advantages of the present invention:

[0032] The present invention is provided with a shell assembly, a power assembly, a test mechanism, a preservative carrying mechanism, a driving and cleaning mechanism and a positioning mechanism, so that the power assembly can be used to drive the test mechanism to move downward, and then the test mechanism is pressed on the top of the qualitative filter paper. Then the shell assembly blocks the test mechanism, and the subsequent power assembly drives the preservative carrying mechanism to continue to move downward. During the downward movement of the preservative carrying mechanism, the driving and cleaning mechanism drives the preservative carrying mechanism to flip it, so as to judge whether the paint film formed by the preservative to be tested is dry according to whether the qualitative filter paper falls. In addition, during the flipping of the preservative carrying mechanism, the positioning mechanism positions the flipped preservative carrying mechanism, so that the subsequent driving and cleaning mechanism can polish and clean the flipped preservative carrying mechanism. Compared with the same type of device in the prior art, the present invention can automatically clean the paint film after the test is completed, which saves manpower and improves the convenience of use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention provides Figure 1-Figure 5 A steel bar preservative drying time testing device shown in the figure comprises a shell component 1, a power component 2 is provided on the top and inside of the shell component 1, a testing mechanism 3 is provided at the bottom of the power component 2, an antiseptic bearing mechanism 4 is provided in the middle of the inner cavity of the shell component 1, a driving cleaning mechanism 5 is provided at the bottom of the inner cavity of the shell component 1, and two groups of positioning mechanisms 6 are provided on the antiseptic bearing mechanism 4;

[0041] The power component 2 drives the test mechanism 3 to move downward, so that the test mechanism 3 is pressed on the top of the qualitative filter paper, and the shell component 1 blocks the test mechanism 3. The power component 2 drives the preservative carrying mechanism 4 to move downward, and the driving and cleaning mechanism 5 drives the downward moving preservative carrying mechanism 4 to flip it over. The positioning mechanism 6 positions the flipped preservative carrying mechanism 4, and the driving and cleaning mechanism 5 polishes and cleans the flipped preservative carrying mechanism 4.

[0042] like Figure 2As shown, the shell assembly 1 includes an outer shell 11, a sealing door 12, a collection tray 13, an intermediate plate 14, an L-shaped support plate 15 and a guide plate 16, wherein a heating resistor is arranged inside the outer shell 11 and a transparent window is arranged at the bottom of the front face, two sealing doors 12 and two L-shaped support plates 15 are arranged, and the two sealing doors 12 are movably connected to the top of the front face of the outer shell 11 through hinges, the collection tray 13 is fixedly arranged at the bottom of the front face of the outer shell 11, the intermediate plate 14 is fixedly arranged in the middle of the inner cavity of the outer shell 11, the two L-shaped support plates 15 are respectively fixedly arranged on both sides of the top of the outer shell 11, and the guide plate 16 is fixedly arranged on the front side of the bottom of the inner cavity of the outer shell 11 and extends to the inner side of the collection tray 13.

[0043] By setting the above structure, after the qualitative filter paper is placed, the sealing door 12 is closed and the heating resistor inside the shell 11 is energized, so that the inside of the shell 11 is heated to a preset temperature to simulate the actual use environment. The setting of the transparent window allows the operator to intuitively see whether the qualitative filter paper has fallen. The setting of the guide plate 16 and the collection tray 13 can guide and collect the fallen qualitative filter paper, thereby facilitating the operator to clean up later.

[0044] like Figure 3 As shown, the power assembly 2 includes a hydraulic cylinder 21, a lifting frame A23, a return spring A24, a lifting frame B25, an extension plate 26 and a guide pressure rod 27, wherein the hydraulic cylinder 21 is fixedly arranged on the top of the outer shell 11, the lifting frame A23 is fixedly connected to the output shaft of the hydraulic cylinder 21, the return spring A24 is fixedly connected between the lifting frame A23 and the lifting frame B25, the lifting frame B25 is slidably penetrated at the bottom of the lifting frame A23, the extension plate 26 is fixedly arranged at the bottom of the side of the lifting frame A23, and the guide pressure rod 27 slides along the vertical direction through the L-shaped support plate 15 and is fixedly connected to the bottom of the extension plate 26.

[0045] like Figure 3 As shown, the testing mechanism 3 includes an end plate 31 and a drying tester 32 , wherein the end plate 31 is fixedly disposed at the bottom end of the lifting frame B25 , and the drying tester 32 is fixedly disposed at the bottom of the end plate 31 .

[0046] By setting the above-mentioned power component 2 and testing mechanism 3, the hydraulic cylinder 21 can drive the lifting frame A23 to move downward when it rotates. When the lifting frame A23 moves downward, the lifting frame B25 is driven downward by the reset spring A24, and the guide pressure rod 27 is driven downward by the extension plate 26. When the lifting frame B25 moves downward, the drying tester 32 is driven downward by the end plate 31 until the drying tester 32 is pressed on the top of the qualitative filter paper, and the end plate 31 is pressed on the top of the two L-shaped support plates 15. At this time, due to the obstruction of the L-shaped support plate 15, the end plate 31 and the drying tester 32 cannot continue to move downward. Subsequently, as the lifting frame A23 continues to move downward, the lifting frame B25 compresses the reset spring A24, and at the same time, the lifting frame A23 continues to drive the guide pressure rod 27 to move downward through the extension plate 26.

[0047] like Figure 4 As shown, the preservative carrying mechanism 4 includes a metal plate 41, a positioning groove 42, a rotating shaft 43, a lifting block 44, a gear 45, a guide column 46 and a reset spring B47, wherein the metal plate 41 is located on the inner side of the middle plate 14, the positioning groove 42 is opened at the top of the metal plate 41, the rotating shaft 43 is fixedly arranged on the side of the metal plate 41, the lifting block 44 and the gear 45 are sequentially sleeved from the inside to the outside on the outside of the rotating shaft 43, the lifting block 44 is rotatably connected to the rotating shaft 43 through a bearing, the gear 45 is fixedly connected to the rotating shaft 43, the guide column 46 slides in the vertical direction through the lifting block 44 and is fixedly connected to the bottom of the inner cavity of the shell 11, and the reset spring B47 is sleeved on the outside of the guide column 46 and is fixedly connected between the inner wall of the shell 11 and the bottom of the lifting block 44.

[0048] By setting the above structure, it is convenient to brush the preservative to be tested in the positioning groove 42 to form a paint film, and then place the qualitative filter paper on the top of the paint film. When the subsequent guide pressure rod 27 descends and fits on the top of the lifting block 44, as the guide pressure rod 27 continues to move downward, the lifting block 44 moves downward synchronously along the guide column 46 and compresses the reset spring B47 during the downward movement. When the lifting block 44 moves downward, it drives the metal plate 41 to move downward synchronously through the rotating shaft 43. When the metal plate 41 moves downward, it drives the qualitative filter paper to detach from the bottom of the drying tester 32.

[0049] like Figure 4 As shown, the driving cleaning mechanism 5 includes a back plate 51, a rack 52, a second motor 53 and a grinding wheel 54, wherein two back plates 51 and two racks 52 are provided, the two back plates 51 are respectively fixedly provided on both sides of the bottom of the inner cavity of the shell 11, the two racks 52 are respectively fixedly provided on the front sides of the two back plates 51, the second motor 53 is fixedly provided at the center of the bottom of the inner cavity of the shell 11, and the grinding wheel 54 is fixedly provided at the top end of the output shaft of the second motor 53.

[0050] By setting the above structure, after the gear 45 is driven by the rotating shaft 43 to mesh with the adjacent rack 52, as the rotating shaft 43 continues to move downward, the rack 52 drives the gear 45 to rotate, and when the gear 45 rotates, it drives the metal plate 41 to rotate through the rotating shaft 43 until the gear 45 is disengaged from the rack 52, and the metal plate 41 is turned over. If the paint film has dried within the preset time, the qualitative filter paper falls on the top of the guide plate 16 during the turning process of the metal plate 41 and is output to the inside of the collecting tray 13. If the paint film has not dried within the preset time, the qualitative filter paper adheres to the bottom of the paint film and cannot fall.

[0051] When the metal plate 41 continues to descend after subsequent flipping, the grinding wheel 54 that continuously rotates under the drive of the second motor 53 gradually enters the inner side of the positioning groove 42. At this time, the continuously rotating grinding wheel 54 grinds and removes the tested paint film inside the positioning groove 42 and the qualitative filter paper that has not fallen.

[0052] like Figure 5 As shown, the positioning mechanism 6 includes a fixed ring 61, a first magnet 62 and a second magnet 63, wherein the fixed ring 61 is fixedly sleeved and arranged on the outside of an adjacent rotating shaft 43, and a plurality of the first magnets 62 and the second magnets 63 are arranged, and a plurality of the first magnets 62 are evenly fixedly nested and arranged on the side of the fixed ring 61, and a plurality of the second magnets 63 are evenly fixedly nested and arranged on the side of the lifting block 44 close to the fixed ring 61, and any one of the first magnets 62 is magnetically connected to the adjacent second magnet 63.

[0053] By setting the above structure, during the rotation of the rotating shaft 43, the fixed ring 61 drives the multiple first magnets 62 to rotate, and the multiple first magnets 62 repeat the process of demagnetizing and re-magnetizing with the multiple second magnets 63, and then the rotating shaft 43 is positioned through the fixed ring 61, and the metal plate 41 is positioned through the rotating shaft 43, providing a prerequisite for the subsequent grinding wheel 54 to accurately enter the inner side of the positioning groove 42.

[0054] The present invention also discloses a method for testing the drying time of a steel bar preservative for autoclaved aerated concrete, which is implemented using the above-mentioned steel bar preservative drying time testing device. The method specifically comprises the following steps:

[0055] S1, brush the preservative to be tested in the positioning groove 42 to form a paint film, then place the qualitative filter paper on the top of the paint film, close the sealing door 12 and energize the heating resistor inside the housing 11, so that the temperature inside the housing 11 rises to a preset temperature;

[0057] S3, as the drying tester 32 continues to move downward, the drying tester 32 is pressed on the top of the qualitative filter paper, and the end plate 31 is pressed on the top of the two L-shaped support plates 15. At this time, due to the obstruction of the L-shaped support plates 15, the end plate 31 and the drying tester 32 cannot continue to move downward. Subsequently, as the lifting frame A23 continues to move downward, the reset spring A24 is compressed, and the lifting frame A23 continues to drive the guide pressure rod 27 to move downward through the extension plate 26;

[0058] S4, the bottom end of the guide pressure rod 27 is attached to the top of the lifting block 44, and the lifting block 44 is subsequently moved down synchronously along the guide column 46 and compresses the reset spring B47 during the downward movement. When the lifting block 44 moves down, the metal plate 41 is driven to move down synchronously through the rotating shaft 43, and when the metal plate 41 moves down, the qualitative filter paper is driven to detach from the bottom of the drying tester 32;

[0059] S5, the gear 45 is driven by the rotating shaft 43 to mesh with the adjacent rack 52. Subsequently, as the rotating shaft 43 continues to move downward, the rack 52 drives the gear 45 to rotate. When the gear 45 rotates, the metal plate 41 is driven to rotate through the rotating shaft 43. During the rotation of the rotating shaft 43, the plurality of first magnets 62 are driven to rotate through the fixed collar 61. The plurality of first magnets 62 and the plurality of second magnets 63 repeat the process of releasing and re-attracting the magnets.

[0060] S6, the gear 45 and the rack 52 end the meshing and disengage, and the metal plate 41 is turned over. If the paint film has dried within the preset time, the qualitative filter paper falls on the top of the guide plate 16 during the turning of the metal plate 41 and is output to the inside of the collection tray 13. If the paint film has not dried within the preset time, the qualitative filter paper adheres to the bottom of the paint film and cannot fall.

[0061] S7, the continuously rotating grinding wheel 54 is driven by the second motor 53 to enter the inner side of the positioning groove 42, and the continuously rotating grinding wheel 54 removes the tested paint film and the qualitative filter paper that has not fallen inside the positioning groove 42;

[0062] S8, the paint film inside the positioning groove 42 is cleaned, so that the hydraulic cylinder 21 drives the lifting frame A23 to move up and reset. During the upward movement of the lifting frame A23, the preservative bearing mechanism 4 and the testing mechanism 3 are reset synchronously;

[0063] S9. After the lifting frame A23 reaches the initial position, the hydraulic cylinder 21 stops running, and then the sealing door 12 is opened.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.

6. A method for testing the drying time of a steel bar preservative for autoclaved aerated concrete, characterized in that: The method is implemented using the steel bar preservative drying time testing device as claimed in claim 5, and the method specifically comprises the following steps: S1. Apply the preservative to be tested in the positioning groove to form a paint film, then place the qualitative filter paper on the top of the paint film, close the sealing door and energize the heating resistor inside the shell, so that the temperature inside the shell rises to a preset temperature; S2, when the hydraulic cylinder rotates, it drives the lifting frame A to move downward, when the lifting frame A moves downward, it drives the lifting frame B to move downward through the reset spring A, drives the guide pressure rod to move downward through the extension plate, when the lifting frame B moves downward, it drives the drying tester to move downward through the end plate; S3. As the drying tester continues to move downward, the drying tester is pressed on the top of the qualitative filter paper, and the end plate is pressed on the top of the two L-shaped support plates. At this time, due to the obstruction of the L-shaped support plates, the end plate and the drying tester cannot continue to move downward. Subsequently, as the lifting frame A continues to move downward, the reset spring A is compressed, and the lifting frame A continues to drive the guide pressure rod to move downward through the extension plate; S4. The bottom end of the guide pressure rod is attached to the top of the lifting block. The lifting block then moves down synchronously along the guide column and compresses the reset spring B during the downward movement. When the lifting block moves down, the metal plate is driven to move down synchronously through the rotating shaft. When the metal plate moves down, the qualitative filter paper is driven to detach from the bottom of the drying tester. S5. The gear is driven by the rotating shaft to mesh with the adjacent rack. Subsequently, as the rotating shaft continues to move downward, the rack drives the gear to rotate. When the gear rotates, the metal plate is driven to rotate through the rotating shaft. During the rotation of the rotating shaft, the plurality of first magnets are driven to rotate through the fixed collar. The plurality of first magnets are repeatedly demagnetized and re-magnetized with the plurality of second magnets in succession. S6, the gear and the rack stop meshing and disengage, and the metal plate is flipped over. If the paint film has dried within the preset time, the qualitative filter paper falls on the top of the guide plate during the flipping of the metal plate and is output to the inside of the collection tray. If the paint film has not dried within the preset time, the qualitative filter paper adheres to the bottom of the paint film and cannot fall. S7, the continuously rotating grinding wheel is driven by the second motor to enter the inner side of the positioning groove, and the continuously rotating grinding wheel removes the tested paint film and the qualitative filter paper that has not fallen inside the positioning groove; S8. After the paint film on the inner side of the positioning groove is cleaned, the hydraulic cylinder drives the lifting frame A to move upward and reset. During the upward movement of the lifting frame A, the preservative bearing mechanism and the testing mechanism are reset synchronously; S9. After the lifting frame A reaches the initial position, the hydraulic cylinder stops running and then the sealing door is opened.
