DETAILED DESCRIPTION

[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] Example: A rock mechanical property testing device, such as Figure 1 As shown, the test assembly includes a protective frame 1, a cylinder 2, a test component 3, a first electric slide rail 4, a first slider 5, a protective plate 6, a placement plate 10, and a transparent plate 7. The cylinder 2 is mounted on the upper side of the upper part of the protective frame 1 via fasteners. The test component 3 is welded to the lower side of the upper part of the protective frame 1. The first electric slide rail 4 is bolted to the front side of the protective frame 1. The first slider 5 is symmetrically slidably connected to the first electric slide rail 4. The protective plate 6 is welded to each of the first slider 5. The placement plate 10 is slidably connected to the lower side of the interior of the protective frame 1. The transparent plate 7 is connected to each of the protective plates 6. When the cylinder 2 is activated, pressure is applied to the rock sample. During this process, the rock may deform or crack. The protective plate 6 can not only effectively prevent rock fragments from flying outwards, ensuring the safety of the staff, but also allow the staff to observe the changes in the rock through the transparent plate 7, ensuring that the testing process is both safe and intuitive.

[0021] like Figure 1 As shown, it also includes fixing rods 31. Four fixing rods 31 are threadedly connected to the test assembly 3. Then, the position of the fixing rods 31 is rotated so that the opposite end of the fixing rods 31 contacts the rock sample to ensure that the rock sample is firmly fixed, which facilitates the smooth progress of subsequent tests.

[0022] like Figures 2-4 As shown, it also includes a second electric slide rail 8 and a second slider 9. The second electric slide rail 8 is installed inside the protective frame 1 through a connector. The second slider 9 is slidably connected to the second electric slide rail 8 from left to right. The placement plate 10 is welded to the second slider 9 respectively.

[0023] like Figures 1-4As shown, it also includes rubber pads 11, collection frame 12 and lighting 13, the placement plate 10 is adhered with rubber pads 11, rubber pads 11 can increase the friction between the rock sample and the placement plate 10, effectively prevent the rock sample bottom slip in the subsequent test process, ensure the accuracy of test data; the lower part of the protective frame 1 is slidably connected with the collection frame 12, the final rock fragments will fall into the collection frame 12, which is convenient for subsequent centralized processing; the upper part of the protective frame 1 is installed with lighting 13 through the fixing piece, considering the problem that the rock sample placed in the protective frame 1 may cause insufficient light, the lighting 13 should be turned on to provide sufficient lighting conditions for the inside of the device, so that the staff can more clearly observe the state of the rock sample.

[0024] When the device needs to be used to test the rock, first, the rock sample is placed on the placement plate 10 with rubber pads 11, which can increase the friction between the rock sample and the placement plate 10, effectively preventing the rock sample bottom slip in the subsequent test process, ensuring the accuracy of test data; then, rotate the position of the fixed rod 31, the opposite end of the fixed rod 31 is in contact with the rock sample to ensure that the rock sample is firmly fixed, facilitating the smooth progress of subsequent testing; subsequently, start the first electric sliding rail 4, which will drive the first sliding block 5 and the protective plate 6 to move synchronously to shield the front side of the protective frame 1, and start the air cylinder 2 to apply pressure to the rock sample, in this process, the rock may be deformed or broken, the protective plate 6 can not only effectively prevent the rock fragments from splashing outward, ensuring the safety of the staff, but also the staff can observe the changes of the rock through the transparent plate 7, ensuring that the test process is safe and intuitive; considering the problem that the rock sample placed in the protective frame 1 may cause insufficient light, the lighting 13 should be turned on to provide sufficient lighting conditions for the inside of the device, so that the staff can more clearly observe the state of the rock sample, after the test is completed, the first electric sliding rail 4 is started again to open the protective plate 6, and the rock sample on the rubber pad 11 is removed, since the rock sample may have been broken, there may be rock fragments on the rubber pad 11, if not cleaned in time, it will affect the stable placement of the next rock sample, at this time, the second electric sliding rail 8 is started to move the placement plate 10 to the left and right directions, the rock fragments on the rubber pad 11 will contact and be removed from the bottom surface of the upper part of the protective frame 1 during the movement, so that the next rock sample can be placed smoothly, and finally the rock fragments will fall into the collection frame 12, which is convenient for subsequent centralized processing; the subsequent test work repeats the above steps, and after the work is completed, the device is cleaned and turned off.

[0025] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
