At the same time, after testing the road surface, the test results can only be obtained through pressure, so the test data will have errors and the whole process has limitations. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 One embodiment provided by this utility model: A hardness testing device for compacted road surfaces is disclosed in this application. The cylinder body 10, auxiliary ball 14, and pressure ring 20 used in this application are all commercially available products, and their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here. The device includes a base 1, with a middle plate 2 fixedly connected to the upper surface of the base 1. A testing component is installed on the top surface of the base 1, and a test component is installed on the right side of the base 1. The detection assembly includes a detection cylinder 3 and a connecting block 7. The detection cylinder 3 is installed on the top surface of the base 1. There are two sets of detection cylinders 3. The inside of the detection cylinder 3 is provided with a slot 4. The inside of the slot 4 is equipped with a moving rod 5. The lower surface of the moving rod 5 is equipped with a contact detection ring 6. The front and rear surfaces of the intermediate plate 2 are fixedly connected with side blocks 9. The top surface of the side block 9 is equipped with a cylinder body 10. The lower end of the cylinder body 10 passes through the inside of the side block 9 and is equipped with a contact block 11. The lower surface of the contact block 11 abuts against the upper surface of the moving rod 5.

[0019] The testing assembly includes a chute 12, which is located on the right side surface of the base 1. A sliding plate 13 is slidably mounted inside the chute 12. Auxiliary balls 14 are mounted on both the upper and lower sides of the sliding plate 13. A detection plate 15 is fixedly connected to the right side of the sliding plate 13. A bottom groove 16 is formed on the lower surface of the detection plate 15. A limiting groove 17 is formed on the inner wall of the detection plate 15. A mounting post 18 is installed inside the limiting groove 17. A moving ball 19 is mounted on the outer surface of the mounting post 18. A pressure ring 20 is mounted on the top surface of the inner wall of the detection plate 15. The pressure ring 20 is mounted above the moving ball 19. A pressure sensor is installed inside the pressure ring 20 and is electrically connected to an external display device. After the road surface hardness is tested, the base 1 and the detection cylinder 3 are moved together to a distance to the left of the testing point. Then, the detection plate 15 is moved inside the chute 12. The design of the sliding plate 13 and the auxiliary balls 14 assists in the movement of the detection plate 15. Then, the detection plate 15 is moved back and forth on the bottom surface that is contacted by the contact detection ring 6. If the moving ball 19 can always contact the ground surface that is contacted by the contact detection ring 6, the road surface hardness is good. If the moving ball 19 does not contact the bottom surface that is contacted by the contact detection ring 6, the moving ball 19 will not apply pressure to the pressure ring 20. As a result, the road surface will have grooves after the hardness test, indicating that the road surface hardness is poor. Therefore, this device can detect the hardness of the road surface after testing through the cooperation between the moving ball 19 and the pressure ring 20, and it is quite convenient to use.

[0020] Connecting block 7 is installed on the inner wall of detection cylinder 3. A limiting sleeve 8 is fixedly connected to the end of connecting block 7 away from detection cylinder 3. The limiting sleeve 8 is fitted onto the outer surface of moving rod 5. Detection cylinder 3 and base 1 are interconnected. First, base 1 is placed on the compacted road surface. When testing the road surface hardness, base 1 remains stable relative to the road surface and will not experience relative displacement. At this time, the cylinder body 10 is activated, causing the contact block 11 to move downwards. Then, contact block 11 drives moving rod 5 downwards within detection cylinder 3 and slot 4. The connection block 7 and limiting sleeve 8 ensure that moving rod 5 moves straight downwards, guaranteeing its stability during road surface hardness testing. Then, contact detection ring 6 passes through the interior of base 1 and contacts the ground to perform road surface hardness testing, resulting in a better overall testing effect and higher accuracy. The pressure of the cylinder body 10 is controlled to achieve the detection intensity of the road surface. Since the detection cylinder 3 and the base 1 are interconnected, the base 1 has a through hole that cooperates with the contact detection ring 6. Thus, the base 1 is in a stable state with the ground during the detection process.

[0021] Working Principle: When using this device, the operator first connects it to an external power source to provide power. The base 1 is then placed on the compacted road surface. When testing the road surface hardness, the cylinder body 10 is activated, causing the contact block 11 to move downwards. The contact block 11 then moves the moving rod 5 downwards within the detection cylinder 3 and slot 4. The connecting block 7 and limiting sleeve 8 ensure the moving rod 5 moves straight downwards, guaranteeing its stability during road surface hardness testing. The contact detection ring 6 then passes through the base 1 and contacts the ground to perform the road surface hardness test. After the hardness test, the base 1 is removed as a whole, and the test plate 15 is moved inside the slide groove 12. The design of the sliding plate 13 and the auxiliary ball 14 can assist the test plate 15 in moving. The test plate 15 is then moved back and forth on the bottom surface that is contacted by the contact test ring 6. If the moving ball 19 can always contact the ground that is contacted by the contact test ring 6, the road surface hardness is good. If the moving ball 19 does not contact the bottom surface that is contacted by the contact test ring 6, the moving ball 19 will not apply pressure to the pressure ring 20. As a result, the road surface will have grooves after the hardness test, and the road surface hardness is poor. The above is the working principle of this utility model.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
