Description
Technical Field
[0001] This application relates to the field of rock mechanics testing technology, specifically to a portable rock mechanics testing tool. Background Technology
[0002] Rock mechanics testing and analysis are experimental methods used in rock mechanics. They not only reveal the mechanical properties, deformation, and failure patterns of rocks and rock masses, but also provide data on the various physical and mechanical effects of structures on the rock mass, offering necessary parameters for engineering design and construction. Rock mechanics testing typically follows these principles: 1. Combining rock mechanics testing with geological research; 2. Combining the principles of rock mechanics testing with simulations of actual rock mass mechanical processes; 3. Combining large-scale in-situ tests in typical geological units with laboratory sampling tests; 4. Combining quantitative numerical measurement and analysis with research on the mechanisms of rock mass mechanical processes.
[0003] Rock mechanics tests and assessments mainly include: tensile, shear, and compressive tests of rock blocks, as well as rheological tests. Tensile tests of rock blocks include direct tensile methods and indirect tensile methods, the latter of which includes the splitting method, bending test method, and radial expansion method. Shear tests of rock blocks include shear fracture tests and structural surface friction tests. The former is used for intact rock blocks, while the latter is used for structural surfaces in the rock mass, and both are expressed using friction angle and cohesion as their strength parameters. Rock mechanics tests and assessments of rock block compressive tests include uniaxial compressive tests, triaxial compressive tests with equal confining pressure, and triaxial compressive tests with unequal confining pressure.
[0004] When conducting compressive strength tests on rock masses, it is necessary to fix the rock mass. However, since different rock masses have different shapes and sizes, the existing technology mainly uses bench vises to hold the rock mass during rock mechanics testing. However, the bench vise has a large contact area with the rock mass, which can easily lead to an increase in the compressive strength at the test point during rock mass pressure testing, resulting in inaccurate test results. At the same time, the bench vise can only serve to fix the rock mass.
[0005] In view of this, it is necessary to provide a portable rock mechanics testing tool to solve the above problems. Summary of the Invention

[0016] In this embodiment, by fixing the second telescopic cylinder to the mounting bracket and base, the stability of the pressure test and the robustness of the test tool can be increased.

[0018] In this embodiment, by setting a control device, the extension and retraction movements of the first telescopic cylinder and the second telescopic cylinder can be controlled, thereby enabling the conical clamping head and the conical pressure detection clamping head to automatically clamp and detect the rock mass.
[0019] In some embodiments, a plurality of rubber pads are equidistantly arranged on the bottom of the base.
[0020] In this embodiment, the stability of the testing tool can be greatly increased by placing a rubber pad on the base.

[0036] Currently, rock mechanics testing tools mainly use bench vises to hold the rock mass. However, the contact area between the bench vise and the rock mass is large, which increases the compressive strength at the test point and leads to inaccurate test results. In addition, the bench vise can only serve to fix the rock mass.
[0037] To address the issues of inaccurate test results caused by clamping devices and their limited functionality, this application provides a portable rock mechanics testing tool. This tool prevents excessively large clamping areas from affecting the accuracy of rock pressure testing and enhances the functionality of the clamping head. Furthermore, the device is easy to install and disassemble, portable, and durable, thus increasing ease of use.
[0038] The present application will be further described below with reference to specific implementation methods.
[0039] Please see Figures 1-3 This application provides a portable rock mechanics testing tool, including a mounting frame 1, a clamping device, a pressure detection device, and a base 6; wherein, the clamping device includes a plurality of first telescopic cylinders 21 symmetrically fixed inside the mounting frame 1 and conical clamping heads 22 connected to the first telescopic cylinders 21; the pressure detection device includes second telescopic cylinders 31 symmetrically fixed outside the mounting frame 1, and conical pressure detection clamping heads 32 connected to the telescopic ends of the second telescopic cylinders 31; the mounting frame 1 is fixed on the base 6.
[0040] In the above manner, the first telescopic cylinder 21 drives the conical clamping head 22 and the second telescopic cylinder 31 drives the conical pressure detection clamping head 32, which can clamp rock masses of different sizes and shapes at points, preventing the clamping area from being too large and affecting the accuracy of rock pressure detection; the conical pressure detection clamping head 32 can perform pressure detection on the rock mass while clamping it; fixing the mounting frame 1 on the base 6 greatly increases the stability of the testing tool.
[0041] Furthermore, in this embodiment, the mounting bracket 1 is ring-shaped.
[0042] By designing the mounting frame 1 as a ring, the clamping head can form a circumferential clamping around the test rock mass, thereby enabling clamping of rock masses of different shapes while providing greater stability.
[0043] Furthermore, in this embodiment of the application, the mounting bracket 1 is symmetrically provided with sleeves 12 that penetrate the mounting bracket 1 on its left and right sides; the telescopic part of the second telescopic cylinder 31 passes horizontally through the sleeves 12.
[0044] In the above manner, by setting up symmetrical sleeves 12 on the left and right sides, the telescopic part of the second telescopic cylinder 31 can pass through the mounting frame 1 so that the conical pressure detection clamping head 32 can cooperate with the conical clamping head 22 to form a symmetrical surrounding clamping of the rock mass, and at the same time perform pressure detection on the rock mass.
[0045] Furthermore, in this embodiment of the application, the first telescopic cylinder 21 is uniformly and symmetrically fixed to the upper and lower halves of the mounting frame 1 by the mounting base 11; preferably, there are six sets of the first telescopic cylinder 21, three sets on the upper and three sets on the lower.
[0046] By means of the above method, the first telescopic cylinder 21 is evenly and symmetrically fixed in the upper and lower parts of the mounting bracket 1, so that the surrounding clamping points are evenly distributed and the clamping is more stable.
[0047] Furthermore, in this embodiment, the upper and lower ends of the second telescopic cylinder 31 are respectively connected to a first connecting rod 42 and a second connecting rod 43 via a mounting plate 41, and the other ends of the first connecting rod 42 and the second connecting rod 43 are respectively fixed to the outside of the mounting frame 1 via a fixing plate 44; the middle part of the second connecting rod 43 is fixed to the base 6.
[0048] The second connecting rod 43 has a locking block in the middle, which engages with the locking post on the upper part of the base 6 and is fixed by bolts.
[0049] By fixing the second telescopic cylinder 31 to the mounting bracket 1 and the base 6 in the above manner, the stability of the pressure test and the robustness of the test tool can be increased.
[0050] Furthermore, in this embodiment of the application, a control device 5 is provided at the bottom of the mounting bracket 1, and the bottom end of the control device 5 is connected to the base 6; the control device 5 is electrically connected to the first telescopic cylinder 21 and the second telescopic cylinder 31.
[0051] By setting up the control device 5 in the above manner, the extension and retraction movements of the first telescopic cylinder 21 and the second telescopic cylinder 31 can be controlled, thereby enabling the conical clamping head 22 and the conical pressure detection clamping head 32 to automatically clamp and detect the rock mass.
[0052] Furthermore, in this embodiment of the application, a plurality of rubber pads 61 are equidistantly arranged on the bottom of the base 6.
[0053] By using the above method, setting a rubber pad 61 on the base 6 can greatly increase the stability of the testing tool.
[0054] Furthermore, in this embodiment, both the conical clamping head 22 and the conical pressure detection clamping head 32 are provided with rubber sleeves 7 on their exteriors; the conical clamping head 22 is detachably connected to the first telescopic cylinder 21, and the conical pressure detection clamping head 32 is detachably connected to the second telescopic cylinder 31.
[0055] By using the above method, rubber sleeves 7 are installed on the outside of the conical clamping head 22 and the conical pressure detection clamping head 32, which can greatly increase the stability of the rock mass clamping.
[0056] The working process of the portable rock mechanics testing tool provided in this application is roughly as follows:
[0057] During use, the rock mass is placed in the middle of the annular mounting frame 1. The control system 5 starts the first telescopic cylinder 21. Driven by the first telescopic cylinder 21, the conical clamping head 22 clamps the three points at the upper and lower ends of the rock mass. Then, the second telescopic cylinder 31 is started. The second telescopic cylinder 31 applies a thrust to the conical pressure detection clamping head 32 and performs compressive strength testing on the corresponding positions at both ends of the rock mass. After the test is completed, the first telescopic cylinder 21 and the second telescopic cylinder 31 retract, and the clamping head retracts to clamp the rock mass.
