[0023] Example 1
[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a lime-soil pavement structural performance testing device, comprising: a strength testing machine 1, the top of the strength testing machine 1 is provided with a collecting mechanism 2, the collecting mechanism 2 includes two annular sleeves 21, the annular sleeves 21 are sleeved on the outer surface of the strength testing machine 1, one of the annular sleeves 21 is fixedly connected to the top of a protective cover 22, and the other annular sleeve 21 is fixedly connected to the top of a protective cover 23, the interior of the protective cover 22 and the protective cover 23 are provided with... The collection trough 24 has an elastic cloth 25 on the top of the protective cover 22. Both the protective cover 22 and the protective cover 23 have annular grooves 26. An elastic ring 27 is fitted inside the annular groove 26 and is fixedly connected to the elastic cloth 25. An elastic ring 28 is provided on the top of the elastic cloth 25 and is fixedly connected to the elastic cloth 25. The annular sleeve 21 is slidably connected to the strength testing machine 1. The elastic ring 28 is fitted onto the outer surface of the strength testing machine 1 and is slidably connected to the strength testing machine 1.
[0025] In this embodiment, by setting two annular sleeves 21, the two annular sleeves 21 can fit onto the outer surface of the strength testing machine 1 testing component located at the bottom of the test sample, allowing the collection mechanism 2 to operate stably. Protective covers 22 and 23 are provided, and are positioned outside the test sample, thus blocking splashed fragments of the test sample. Both protective covers 22 and 23 are provided with collection grooves 24. The ring-shaped collection groove 24 can collect the debris blocked by the first protective cover 22 and the second protective cover 23. In addition, an elastic cloth 25 is provided, and the elastic cloth 25 is elastic, so even when the pressure component of the strength testing machine 1 moves down, the elastic cloth 25 can be used in conjunction with it and will not affect the normal use of the strength testing machine 1. An elastic ring 27 and an elastic ring 28 are provided, and the elastic ring 27 and the elastic ring 28 can deform. Therefore, the elastic ring 27 and the elastic ring 28 can be easily connected or disconnected from the pressure component of the strength testing machine 1 and the first protective cover 22 and the second protective cover 23.
[0026] Example 2
[0027] like Figures 1-5 As shown, a fixing mechanism 3 is provided on one side of the protective cover 22. The fixing mechanism 3 includes a connecting block 31, which is fixedly connected to the protective cover 22. An insert block 32 is sleeved inside the connecting block 31 and is slidably connected to the connecting block 31. The insert block 32 is fixedly connected to the protective cover 23. An angled block 33 is sleeved inside the connecting block 31 and the insert block 32 and is slidably connected to both the connecting block 31 and the insert block 32. A moving block 34 is provided at one end of the angled block 33 and is fixedly connected to the angled block 33. The moving block 34 is sleeved inside the connecting block 31 and is slidably connected to the connecting block 31. A spring 35 is provided on one side of the moving block 34 and a slider 36 is provided at one end of the moving block 34 and is fixedly connected to the moving block 34.
[0028] In this embodiment, by setting a fixing mechanism 3, the annular sleeve 21 can be stably installed on the outer surface of the testing component of the strength testing machine 1. An insert block 32 is provided, and the insert block 32 has a slot that matches the beveled block 33. Therefore, the beveled block 33 can be engaged with the insert block 32, so that the insert block 32 and the connecting block 31 are firmly connected. At the same time, a spring 35 is provided, and the spring 35 can generate elastic force. The elastic force of the spring 35 can act on the beveled block 33 through the moving block 34, so that the beveled block 33 and the insert block 32 are in a tightly engaged connection.
[0029] Working principle:
[0030] like Figures 1-5 As shown, in use, the cylindrical sample to be tested can be placed on top of the testing component of the strength testing machine 1. Then, two annular sleeves 21 are installed from both sides of the testing component, so that the two annular sleeves 21 fit onto the outer surface of the testing component. During installation, the protective cover 1 22 and the protective cover 23 will gradually move closer together, and the insert 32 fixedly connected to the outer surface of the protective cover 23 will gradually enter the interior of the connecting block 31 fixedly connected to the outer surface of the protective cover 1 22. At the same time, the insert 32 will be in the connecting block 31. When sliding inward, the beveled block 33 is pressed, causing it to slide into the interior of the connecting block 31. As the beveled block 33 slides, it moves the moving block 34, which in turn compresses the spring 35, causing it to generate elastic force. When the first protective cover 22 and the second protective cover 23 are fully engaged, the elastic force of the spring 35 is released instantly, resetting the beveled block 33 and causing it to engage inside the insert block 32. At this point, the annular sleeve 21, the first protective cover 22, and the second protective cover 23 are stable. The test sample is fitted onto the outer surface of the testing component of the strength testing machine 1. Then, elastic ring 27 and elastic ring 28 are pulled. At this time, elastic ring 27 will fit inside the annular groove 26 on the protective cover 22 and the protective cover 23, while elastic ring 28 will fit inside the inner groove on the pressure component of the strength testing machine 1. The entire test sample will be enclosed. Then, the strength testing machine 1 is started, and the pressure component of the strength testing machine 1 will apply pressure to the test sample from the top. The sensor of the strength testing machine 1 will then... The test data is fed back. When the test sample splashes, the splashed debris will be blocked by the first protective cover 22 and the second protective cover 23 and fall into the inside of the collection tank 24. When it is necessary to clean up the debris, the first elastic ring 27 and the second elastic ring 28 can be removed first, and then the slider 36 can be slid. The slider 36 will use the moving block 34 to drive the angled block 33, so that the angled block 33 is separated from the insert block 32. Thus, the insert block 32 can be separated from the connecting block 31. Finally, the second protective cover 23 is separated from the first protective cover 22, and the collected debris can be poured out.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
