[0024] Please see Figure 1-4 This utility model provides a technical solution: a device for detecting the smoothness of micro-surfacing of emulsified asphalt, including a supporting top plate 1, an installation plate 2 fixed to the side wall of the supporting top plate 1, a first bearing 3 opened inside the supporting top plate 1, a threaded post 4 provided inside the first bearing 3, a hand handle 5 fixed to the top of the threaded post 4, a threaded groove 6 threadedly connected to the outer periphery of the threaded post 4, and a support frame 7 provided outside the threaded groove 6.
[0025] A first motor 8 is fixed to the side wall of the support frame 7. A first rotating shaft 9 is provided at the rotating end of the first motor 8. A sector gear 10 is fixed to the other end of the first rotating shaft 9. A ring rack 11 is meshed with the outer side of the sector gear 10. A connecting frame 12 is fixed to the outer wall of the ring rack 11. A first limiting groove 13 is provided on the outer side of the connecting frame 12. A flatness detection module 14 is provided at the other end of the connecting frame 12. A sensing plate 15 is provided on one side of the flatness detection module 14. A second limiting groove 16 is opened inside the other end of the support frame 7. A limiting post 17 is provided on the inner side of the second limiting groove 16.
[0026] Furthermore, a second motor 18 is fixed to the lower surface of the supporting top plate 1. A second rotating shaft 19 is provided at the rotating end of the second motor 18. A first bevel gear 20 is fixed to the other end of the second rotating shaft 19. A second bevel gear 21 is meshed with one side of the first bevel gear 20. A connecting column 22 is fixed inside the second bevel gear 21. A second bearing 23 is provided on the outside of the connecting column 22. A fixing plate 24 is provided on the outside of the second bearing 23.
[0027] Furthermore, a rotating plate 25 is fixed to the top of the connecting column 22, a movable plate 27 is provided on one side of the rotating plate 25, a third rotating shaft 26 is provided at the connection between the rotating plate 25 and the movable plate 27, a cylindrical slider 29 is provided at the other end of the movable plate 27, a fourth rotating shaft 28 is provided at the connection between the movable plate 27 and the cylindrical slider 29, a slide rail 30 is provided on the outer side of the cylindrical slider 29, and a pressing plate 31 is fixed to the side wall of the slide rail 30.
[0028] Furthermore, the threaded column 4 forms a rotating structure with the supporting top plate 1 through the first bearing 3, and the threaded column 4 forms a threaded connection with the support frame 7 through the threaded groove 6. The threaded column 4 and the hand handle 5 form a fixed structure, and the support frame 7 forms a sliding structure with the limiting column 17 through the second limiting groove 16. By rotating the hand handle 5 with external force, the threaded column 4 can be driven to rotate. Through the threaded connection between the threaded column 4 and the threaded groove 6, the rotation of the threaded column 4 can raise and lower the support frame 7, thereby adjusting the height of the sensing device and adjusting the distance between the sensing plate 15 and the road surface as needed.
[0029] Furthermore, the sector gear 10 and the first rotating shaft 9 form a rotating structure through the operation of the first motor 8, and the sector gear 10 and the ring rack 11 form a meshing structure. The ring rack 11 forms a fixed structure with the flatness detection module 14 through the connecting frame 12. When the first motor 8 is turned on, the sector gear 10 can be driven to rotate. Through the meshing structure of the sector gear 10 and the ring rack 11, the rotation of the sector gear 10 can cause the ring rack 11 to reciprocate, thereby causing the flatness detection module 14 to reciprocate and detect. The flatness detection module 14 is usually composed of a sensing plate 15, a data processing unit, and a display interface. The sensing plate 15 is responsible for sensing the microscopic unevenness of the surface being measured, and the data processing unit converts these sensing data into readable flatness indicators, which are finally presented to the user through the display interface.
[0030] Furthermore, the first bevel gear 20 and the second rotating shaft 19 form a rotating structure through the operation of the second motor 18, and the first bevel gear 20 and the second bevel gear 21 form a meshing structure. The second bevel gear 21 forms a fixed structure with the rotating plate 25 through the connecting column 22, and the connecting column 22 forms a rotating structure with the fixed plate 24 through the second bearing 23. When the second motor 18 is turned on, the second rotating shaft 19 and the first bevel gear 20 can be driven to rotate. Through the meshing structure of the first bevel gear 20 and the second bevel gear 21, the rotation of the first bevel gear 20 can cause the second bevel gear 21 to rotate. The rotation of the second bevel gear 21 indirectly drives the connecting column 22 and the rotating plate 25 to rotate.
[0031] Furthermore, the rotating plate 25 forms a rotating structure with the movable plate 27 via the third rotating shaft 26, and the movable plate 27 forms a rotating structure with the cylindrical slider 29 via the fourth rotating shaft 28. The cylindrical slider 29 forms a sliding structure with the slide rail 30. The rotation of the rotating plate 25 can move the movable plate 27, and the movement of the movable plate 27 can cause the cylindrical slider 29 to slide back and forth via the slide rail 30, which can cause the pressing plate 31 to move back and forth, so that the pressing plate 31 can quickly flatten the uneven road surface.
[0032] Working principle: First, the operator needs to rotate the handle 5 by external force, which will drive the threaded column 4 to rotate. The rotation of the threaded column 4 will raise or lower the support frame 7, thereby adjusting the height of the sensing device and adjusting the distance between the sensing plate 15 and the road surface as needed. The activation of the first motor 8 will drive the sector gear 10 to rotate. Through the meshing structure between the sector gear 10 and the ring rack 11, the rotation of the sector gear 10 will cause the ring rack 11 to reciprocate, thus causing the flatness detection module 14 to reciprocate for detection. The activation of the second motor 18 will... The first bevel gear 20 and the second bevel shaft 19 are driven to rotate. Through the meshing structure of the first bevel gear 20 and the second bevel gear 21, the rotation of the first bevel gear 20 can cause the second bevel gear 21 to rotate. The rotation of the second bevel gear 21 indirectly drives the connecting column 22 and the rotating plate 25 to rotate. The rotation of the rotating plate 25 can cause the movable plate 27 to move. The movement of the movable plate 27 can cause the cylindrical slider 29 to slide back and forth through the slide rail 30, which can cause the pressing plate 31 to move back and forth, so that the pressing plate 31 can quickly flatten the uneven road surface.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
