Specific implementation manners

[0028] The following combines specific implementation cases and attached Figures 1 to 4 to further illustrate the present utility model, but the present utility model is not limited to these embodiments.

[0029] Refer to Figures 1 to 3 As shown, an emulsified asphalt adhesion tester includes a detector main body 1. The detector main body 1 is provided with a detection end. Both the detector main body 1 and the detection end are existing technologies, and it only needs to meet the requirement of asphalt adhesion detection. Its model, operation method, connection relationship, etc. are not limited here. An asphalt felt 2 is placed on the upper surface of the detector main body 1. A positioning plate 5 is rotatably arranged at the top of the asphalt felt 2. A limiting groove 6 is opened in the middle of the positioning plate 5. The detection end of the detector main body 1 is arranged corresponding to the limiting groove 6 up and down. An annular test mold 7 is placed in the inner cavity of the limiting groove 6. The position of the annular test mold 7 can be guided through the limiting groove 6 to ensure that the annular test mold 7 is placed in a position corresponding to the detection end after being placed. Four connecting rods 4 are respectively vertically and fixedly installed at the four corners of the bottom end of the positioning plate 5. A positioning piece 3 is fixedly installed at the bottom end of each connecting rod 4. The four positioning pieces 3 are positioned at the four corners of the upper surface of the asphalt felt 2, which can ensure that when the annular test mold 7 is placed on the upper surface of the asphalt felt 2, the asphalt felt 2 remains stable and does not shift.

[0030] Specifically refer to Figure 3 As shown, a lifting component is arranged at the top end of the positioning plate 5. The lifting component includes a connecting frame 8 fixedly installed at the rear side of the upper surface of the positioning plate 5, and further includes a cylinder 9 installed in the middle of the top end of the connecting frame 8. The cylinder 9 is used to drive the connecting frame 8 and the positioning plate 5 to move in the vertical direction. By opening the cylinder 9, the connecting frame 8 and the positioning plate 5 are driven to move downward synchronously, so as to realize the synchronous downward movement of the connecting rods 4 and the positioning pieces 3 at the four corners of the bottom end of the positioning plate 5 until the positioning pieces 3 press on the upper surface of the asphalt felt 2 to ensure the stability of the asphalt felt 2.

[0031] Refer to Figure 3As shown, the positioning plate 5 is rotatably arranged relative to the detector body 1 through a rotating unit; the rotating unit includes a first rotating rod 11 rotatably arranged on the surface of the detector body 1, a first gear 12 and a rotating arm 10 are fixedly installed on the first rotating rod 11, and the rotating arm 10 is located above the first gear 12. The air cylinder 9 is installed at the free end of the rotating arm 10. The rotation of the rotating arm 10 realizes the rotation of the air cylinder 9, the connecting frame 8 and the positioning plate 5. The rotation of the first gear 12 causes the rotating rod 11 to drive the rotating arm 10, the air cylinder 9, the connecting frame 8 and the positioning plate 5 to rotate synchronously, so as to realize the adjustment of the position of the positioning plate 5.

[0032] Refer to Figure 2 and Figure 3 As shown, an installation plate 14 is fixedly installed on the surface of the detector body 1. The top of the inner side wall of the installation plate 14 is fixedly installed with an installation seat 15. A motor 16 is installed on the top of the installation seat 15. The output end of the motor 16 is connected with a second rotating rod 17. A second gear 18 is fixedly installed on the second rotating rod 17. The second gear 18 is meshed and connected with the motor 16. By starting the motor 16, the second rotating rod 17 and the second gear 18 are driven to rotate, and then the first gear 12 is driven to rotate clockwise, so that the first rotating rod 11, the rotating arm 10 and the positioning plate 5 rotate clockwise synchronously until the side wall of the rotating arm 10 fits against the first limiting part 19. At this time, the positioning plate 5 completely disengages from the detection end of the detector body 1, ensuring that the positioning plate 5 will not cause interference during the subsequent detection process.

[0033] In addition, refer to Figure 3 As shown, the installation plate 14 is of a semi-enclosed structure. The edge of the side wall of the installation plate 14 is divided into a first limiting part 19 and a second limiting part 20. The side wall of the rotating arm 10 rotates and fits against the first limiting part 19 or the second limiting part 20. The rotating arm 10 is adjusted to the initial position where the side wall fits against the second limiting part 20. At this time, the center of the limiting groove 6 just aligns with the detection end of the detector body 1. Then the annular test mold 7 placed at this time is just located below the detection end of the detector body 1, ensuring the accuracy of the placement of the annular test mold 7 without subsequent adjustment; when the first rotating rod 11, the rotating arm 10 and the positioning plate 5 rotate clockwise synchronously until the side wall of the rotating arm 10 fits against the first limiting part 19, at this time the positioning plate 5 completely disengages from the detection end of the detector body 1, ensuring that the positioning plate 5 will not cause interference during the subsequent detection process.

[0034] In addition, refer to Figure 3As shown in the figure, a rotating shaft 21 is rotatably arranged on the upper surface of the positioning plate 5 through a bearing. A rotating plate 22 is fixedly installed on the rotating shaft 21. A scraping plate 23 is fixedly installed on the lower surface of the rotating plate 22. A handle 24 is fixedly and vertically installed on the upper surface of the rotating plate 22. By driving the handle 24, it is more convenient to drive the rotating plate 22 to rotate. Place the sample in the inner cavity of the annular test mold 7. Drive the handle 24 to drive the rotating plate 22 and the scraping plate 23 to rotate, so as to scrape out the sample overflowing from the annular test mold 7 counterclockwise, ensuring that the upper surface of the sample remaining in the inner cavity of the annular test mold 7 is flat, and waiting for the sample to initially set.

[0035] Specifically, the rotation radius of the scraping plate 23 covers the diameter of the annular test mold 7, so as to ensure that the rotating scraping plate 23 can completely scrape off the sample overflowing from the inner cavity of the annular test mold 7, and avoid the defect that it is difficult to completely scrape off the sample in the inner cavity of the annular test mold 7 due to the small rotation radius of the scraping plate 23.

[0036] It should be noted that the cylinder 9 used in this application is a commonly used self-locking cylinder on the market, and its output end can stay at any position and be locked; the motor 16 is a self-locking motor commonly used on the market with an output end that can be locked. When it stops operating, its output end can be self-locked and will not rotate under external force; there is no need to elaborate on the above existing components here.

[0037] The working principle of the emulsified asphalt adhesion tester in this embodiment is as follows:

[0038] Place the asphalt felt 2 on the upper surface of the detector main body 1, so that the asphalt felt 2 is located below the detection end of the detector main body 1; adjust the rotating arm 10 to the initial position where the side wall fits the second limiting part 20. At this time, the center of the limiting groove 6 just aligns with the detection end of the detector main body 1. Place the annular test mold 7 downward along the limiting groove 6, so that the annular test mold 7 is placed on the upper surface of the asphalt felt 2. Under the limiting action of the limiting groove 6, the placed annular test mold 7 is just located below the detection end of the detector main body 1, ensuring the accuracy of the placement of the annular test mold 7 without subsequent adjustment;

[0039] Drive the connecting frame 8 and the positioning plate 5 to move downward synchronously through the opened cylinder 9, and then realize the synchronous downward movement of the connecting rod 4 and the positioning piece 3 at the four corners of the bottom end of the positioning plate 5 until the positioning piece 3 presses the upper surface of the asphalt felt 2 to ensure the stability of the asphalt felt 2;

[0040] Place the sample in the inner cavity of the annular test mold 7. Drive the handle 24 to drive the rotating plate 22 and the scraping plate 23 to rotate, so as to scrape out the sample overflowing from the annular test mold 7 counterclockwise, ensuring that the upper surface of the sample remaining in the inner cavity of the annular test mold 7 is flat, and waiting for the sample to initially set;

[0041] Drive the connecting frame 8, positioning plate 5, and positioning piece 3 through the cylinder 9 to move upward until they are completely separated from the annular test mold 7 and the felt 2. Drive the second rotating rod 17 and the second gear 18 to rotate through the started motor 16, and then drive the first gear 12 to rotate clockwise, prompting the first rotating rod 11, the rotating arm 10, and the positioning plate 5 to rotate clockwise synchronously until the side wall of the rotating arm 10 fits against the first limiting portion 19. At this time, the positioning plate 5 is completely separated from the detection end of the detector main body 1, ensuring that the positioning plate 5 will not cause interference during the subsequent detection process;

[0042] The utility model can guide the placement of the annular test mold 7 to ensure that the placed annular test mold 7 is directly below the detection end of the detector main body 1. There is no need to repeatedly adjust the placement position of the annular test mold 7, and the placement of the annular test mold 7 and the detection of the asphalt adhesion force can be realized more efficiently. At the same time, while guiding the placement of the annular test mold 7, the felt 2 can also be pressed tightly to ensure that the position of the felt 2 is stable and will not shift. In addition, the rotating position of the positioning plate 5 has a limiting function to ensure that the position of the positioning plate 5 is accurate after rotation adjustment and will not interfere with other components.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
