DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example 1

[0030] The present invention provides a rock and soil core testing device, such as Figures 1 to 8As shown, it comprises: a main frame 1, a loading frame 2 is fixedly installed on the top of the main frame 1, a lifting and disassembling assembly 3 is fixedly installed inside the main frame 1, a mounting seat 4 is fixedly installed on the top of the lifting and disassembling assembly 3, a sample container 5 is fixedly installed on the top of the mounting seat 4, an axial loading structure 6 is fixedly installed on the top of the inner wall of the loading frame 2, the axial loading structure 6 is a hydraulic driving rod, and a pressure sensor 7 is installed on the output end of the axial loading structure 6;

[0031] The lifting and disassembly assembly 3 includes a hydraulic rod 31 fixedly installed inside the main frame 1, a mounting plate 32 is fixedly installed on the top of the hydraulic rod 31, the mounting plate 32 is shaped like a boss, a plurality of right-angle rods 35 are slidably connected inside the mounting plate 32, a moving block 38 is fitted and connected to the outer side of the right-angle rods 35, a rack 39 is fixedly installed at one end of the moving block 38, a gear 310 is meshed and connected to the outer side of the rack 39, and an L-shaped fixing plate 311 is fixedly installed on the outer side of the gear 310.

[0032] like Figure 3 and Figure 4 As shown, a plurality of support columns 33 are equidistantly embedded and installed at the top of the fixed end of the hydraulic rod 31, and a same circular ring 34 is installed between the tops of the plurality of support columns 33;

[0033] It can be used to support the circular ring 34, changing the difficulty of supporting the circular ring 34, so that the position of the circular ring 34 can be kept unchanged.

[0034] like Figure 3 and Figure 4 As shown, a rectangular block 314 is fixedly mounted on the top of the mounting plate 32, and a rectangular hole is opened at the bottom of the mounting seat 4 at a position corresponding to the top of the rectangular block 314;

[0035] The rectangular block 314 and the rectangular hole are matched to fix the mounting plate 32 and the mounting seat 4, thereby preventing the mounting seat 4 from swinging left and right.

[0036] like Figure 5 and Figure 6 As shown, a horizontal rod 36 is fixedly installed at one end of the right-angle rod 35, and an inclined angle is provided at one end of the right-angle rod 35 to drive the movement of the moving block 38. A spring expansion member 37 is clamped and installed at the bottom end of the horizontal rod 36, and the spring expansion member 37 is fixedly installed inside the mounting plate 32;

[0037] The horizontal rod 36 is driven to reset under the tensile force of the spring expansion member 37 , and when the horizontal rod 36 is reset, the right-angle rod 35 is driven to reset, thereby changing the difficulty of resetting the right-angle rod 35 .

[0038] like Figure 5 and Figure 6As shown, two guide posts 312 are connected through the rack 39, and the two ends of the two guide posts 312 are fixedly connected to the inside of the mounting plate 32 respectively. A spring driving member 313 is embedded and installed at one end of the moving block 38, and one end of the spring driving member 313 is fixedly installed inside the mounting plate 32. Both ends of the L-shaped fixing plate 311 are rotatably connected with cylinders, and the cylinders are fixedly installed inside the mounting plate 32. An L-shaped groove is opened at the bottom of the mounting seat 4.

[0039] The spring driving member 313 drives the moving block 38 to move, and when the moving block 38 moves, it drives the rack 39 to move along the outside of the guide column 312. The guide column 312 is used to limit the rack 39 to prevent the rack 39 from swinging. When the rack 39 moves, it drives the gear 310 to rotate. When the gear 310 rotates, it drives the L-shaped fixing plate 311 to rotate. When the L-shaped fixing plate 311 rotates, it squeezes the mounting seat 4 along the inside of the L-shaped groove, so that the mounting seat 4 and the mounting disk 32 are squeezed and fixed.

[0040] like Figure 7 and Figure 8 As shown, a positioning detection assembly 8 is installed on the driving shaft of the axial loading structure 6, and the positioning detection assembly 8 includes a mounting plate 81 fixedly installed on the driving shaft of the axial loading structure 6, and a spring lifting member 82 is symmetrically clamped and installed at the bottom end of the mounting plate 81, and an L-shaped limit plate 83 is clamped and installed between the bottom ends of the two spring lifting members 82, and a support rod 84 is fixedly installed inside the L-shaped limit plate 83, and a mounting head 810 is rotatably connected to the top end of the support rod 84, and a horizontal detector 811 is fixedly installed at one end of the mounting head 810;

[0041] Since the driving shaft of the axial loading structure 6 drives the mounting plate 81 to move, when the mounting plate 81 moves, the L-shaped limiting plate 83 fits the top edge of the sample container 5, and the mounting plate 81 continues to move, so that the spring lifting member 82 is compressed. At this time, the horizontal detector 811 detects whether the sample container 5 is installed vertically.

[0042] like Figure 7 and Figure 8 As shown, a concave rod 85 is fixedly installed at one end of the support rod 84, and a protective cover 86 is fixedly installed on the top of the concave rod 85, which can be used for the installation of the protective cover 86, and the level detector 811 is protected by the installed protective cover 86. A rotating member 87 is rotatably connected to the top of the support rod 84, and a mounting head 810 is fixedly installed on the top of the rotating member 87. One end of the mounting head 810 and the fixed end of the level detector 811 are fixedly connected. A mounting strip 88 is fixedly installed at one end of the mounting plate 81, and a column 89 is fixedly installed at the bottom end of the mounting strip 88. The column 89 passes through the mounting head 810, the rotating member 87 and the support rod 84, and a guide block 812 is fixedly installed on the outer side of the column 89. The inner walls of the mounting head 810, the rotating member 87 and the support rod 84 are provided with guide grooves 813.

[0043] When the mounting plate 81 moves, it drives the mounting bar 88 to move, and when the mounting bar 88 moves, it drives the column 89 to move, and when the column 89 moves, it drives the guide block 812 to move in the guide groove 813, and when the guide block 812 moves inside the guide groove 813, it drives the mounting head 810, the rotating member 87 and the support rod 84 to rotate, and when the mounting head 810 rotates, it drives the horizontal detector 811 to rotate, and when the horizontal detector 811 rotates, it detects the top of the sample container 5 in multiple directions, thereby improving the comprehensiveness of the detection.

[0044] Working principle: During the actual use of the device, personnel put the rock and soil sample core into the sample container 5, and then start the axial loading structure 6, which drives the pressure sensor 7 to squeeze it. In this process, the driving shaft of the axial loading structure 6 drives the mounting plate 81 to move. When the mounting plate 81 moves, the L-shaped limit plate 83 fits the top edge of the sample container 5, and then continues to move, so that the spring lifting member 82 is compressed. At this time, when the mounting plate 81 moves, it drives the mounting bar 88 to move, and when the mounting bar 88 moves, it drives the column 89 to move. When the column 89 moves, it drives the guide block 812 to move in the guide groove 813. When the guide block 812 moves inside the guide groove 813, the mounting head 810, the rotating member 87 and the support rod 84 rotate, and the mounting head 810 rotates to drive the horizontal detector 811 to rotate. When the horizontal detector 811 rotates, it detects multiple positions of the top of the sample container 5, thereby improving the verticality of the sample container 5 during placement, and further facilitating the pressure sensor 7 to enter the sample container 5 to squeeze the rock and soil sample core. During the placement of the sample container 5, multiple position detections are achieved, effectively improving the vertical placement accuracy of the sample container 5, thereby facilitating the pressure sensor 7 to penetrate into the sample container 5, and more accurately perform an extrusion test on the rock and soil sample core. A series of operations can be achieved by moving the mounting plate 81, making the entire device structure more compact and more convenient to operate.

[0045] When the sample container 5 needs to be disassembled after use, the hydraulic rod 31 is in operation. The hydraulic rod 31 drives the mounting plate 32 to descend when it is in operation. When the mounting plate 32 descends, it drives the sample container 5 to descend. When the mounting plate 32 descends, the right-angle rod 35 inside fits with the top of the ring 34. At this time, the reaction force of the ring 34 drives the right-angle rod 35 to rise. When the right-angle rod 35 rises, it drives the spring telescopic member 37 to stretch through the horizontal rod 36, and drives the moving block 38 to move under the action of the inclination angle. When the moving block 38 moves, it drives the rack 39 to move inside the guide column 312. At this time, when the rack 39 moves, it drives the gear 310 to rotate. When the gear 310 rotates, it drives the L-shaped fixing plate 311 When the mounting plate 32 is rotated, the L-shaped fixing plate 311 is separated from the mounting seat 4 along the placement groove. At this time, when the bottom end of the maximum outer diameter of the mounting plate 32 is in contact with the top of the main frame 1, the gear 310 and the L-shaped fixing plate 311 are both rotated 180 degrees and completely enter the mounting plate 32. Finally, the mounting seat 4 is taken out, and the mounting seat 4 moves upward along the rectangular block 314 at the top of the mounting plate 32, so that the mounting seat 4 and the lifting and disassembly assembly 3 are separated. This method reduces the height of the sample container 5. Finally, the mounting seat 4 is separated by the gear 310 and the L-shaped fixing plate 311, so that the sample container 5 can be automatically and conveniently disassembled, which greatly improves the efficiency and reduces the risks caused by human factors.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
