Description

Technical Field

[0001] This utility model relates to the technical field of ore body detection devices, and in particular to a ore body stress detection device for geological exploration. Background Technology

[0002] In geological exploration, when conducting stress testing on ore body samples, it is necessary to clamp and fix the samples. However, existing devices for clamping and fixing ore body samples are generally only suitable for samples of specific sizes, making it inconvenient to test samples of different sizes and limiting their applicability. Based on this, patent CN219455715U discloses a support strength testing device for mining. Through two clamping blocks in the clamping mechanism that can move left and right, the device can test samples of different sizes.

[0003] The device clamps the support, and because the two clamping blocks can move left and right, it is not affected by external forces when testing the support strength. However, when testing ore samples, it is inconvenient to test the force on different positions of the clamped ore sample, resulting in poor testing results and a limited testing range.

[0027] The structure and working process of a geological exploration ore body stress detection device of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Reference Figure 1-5 A geological exploration device for detecting the stress on ore bodies includes a workbench 1. A motor 2 is mounted at the bottom of the workbench 1. The output axis of the motor 2 passes through the middle of the workbench 1 and is fixedly connected to one end of a driving bevel gear 3. The diameter of the driving bevel gear 3 is larger than the diameter of four driven bevel gears 4. The driving bevel gear 3 meshes with four driven bevel gears 4.

[0029] The clamping mechanism includes a second rotating rod 9, one end of which horizontally passes through the supporting column 7 and is rotatably connected to it. The first rotating rod 5 and the second rotating rod 9 are fitted together on the outer wall of the outer end of the supporting column 7 with a first belt 6. The second rotating rod 9 and the third rotating rod 17 are fitted together on the outer wall of the outer end of the supporting column 7 with a second belt 16.

A top plate 8 is fixedly installed on the top of the four support columns 7. A detection mechanism is provided at the bottom center of the top plate 8.

[0033] The detection mechanism includes a third rotating rod 17, one end of which horizontally penetrates the support column 7 on either side and is fixedly connected to a first bevel gear 18. A second threaded rod 20 is rotatably connected to the bottom center of the top plate 8. A second bevel gear 19, meshing with the first bevel gear 18, is fixedly connected to the top of the second threaded rod 20. A second hollow rod 21, with a rectangular cross-section, is threaded to the outer periphery of the bottom of the second threaded rod 20. A limiting plate 23, horizontally penetrating the bottom of the second hollow rod 21 and fixed to both ends of the second hollow rod 21 with the support column 7, is provided. The second hollow rod 21 is slidably connected to the limiting plate 23. An anti-detachment block 22 is fixedly connected to the outer periphery of the second hollow rod 21 to prevent it from detaching from the limiting plate 23. A fixing plate 24 is provided at the bottom end of the second hollow rod 21. After the ore sample is clamped and fixed, the force on the ore sample is detected by the downward movement of the fixing plate 24 and the detection head 33.

[0034] A first T-shaped rod 25 is rotatably connected to the fixed plate 24. A movable plate 26 is screwed to the outer periphery of the middle part of the first T-shaped rod 25. A first connecting block 27 is fixed to the top of the movable plate 26. The first connecting block 27 is slidably connected to the fixed plate 24. The detection head 33 can be moved in the X-axis direction by rotating the first T-shaped rod 25.

[0035] A second T-shaped rod 30 is rotatably connected to the movable plate 26. A slider 28 is screwed to the outer periphery of the second T-shaped rod 30. A second connecting block 29 is provided at the top of the slider 28. The second connecting block 29 is slidably connected to the movable plate 26. The detection head 33 can be moved in the Y-axis direction by rotating the second T-shaped rod 30.

[0036] Specifically, the fixed plate 24 is provided with a first sliding groove 40, the movable plate 26 is provided with a second sliding groove 41, the first connecting block 27 is slidably connected to the first sliding groove 40 on the fixed plate 24, and the second connecting block 29 is slidably connected to the second sliding groove 41 on the movable plate 26.

[0037] A pressure sensor 31 is provided at the bottom of the slider 28. The pressure sensor 31 is electrically connected to the control panel 34. The measured value of the pressure sensor 31 can be displayed in real time through the display screen on the control panel 34. A mounting plate 32 is fixedly connected to the bottom of the pressure sensor 31. A detection head 33 is fixedly connected to the bottom of the mounting plate 32. The detection head 33 moves down to detect the force on the clamped and fixed ore sample. The control panel 34 is fixedly connected to the front end of the support column 7 on the left. The motor 2 can be switched on and off by operating the control panel 34.

[0038] When using this device, the operator first places the ore sample to be tested on the workbench 1, starts the motor 2, and the output shaft of the motor 2 drives the driving bevel gear 3 to rotate. The rotation of the driving bevel gear 3 drives the four driven bevel gears 4, the first rotating rod 5, the first belt 6, the second rotating rod 9, the first friction wheel 10, the second friction wheel 11, and the first threaded rod 12 to rotate (the first friction wheel 10 and the second friction wheel 11 rotate synchronously through friction). The rotation of the four first threaded rods 12 drives the four first hollow rods 13 and the clamping plate 15 to move relative to each other. When the clamping plates 15 on the left and right sides come into contact with the ore sample, the second rotating rods 9 and the first friction wheel 10 on the left and right sides continue to rotate, while the second friction wheel 11 and the first threaded rod 12 stop rotating (the first friction wheel 10 and the second friction wheel 11 change from synchronous rotation to the first friction wheel 10 continuing to rotate while the second friction wheel 11 remains stationary), while the clamping plates 15 on the front and rear sides continue to move relative to each other. When the clamping plates 15 on the front and rear sides come into contact with the ore sample, the second rotating rods 9 and the first friction wheel 10 on the front and rear sides continue to rotate, while the second friction wheel 11 and the first threaded rod 12 stop rotating. To prevent rotation (the first friction wheel 10 and the second friction wheel 11 change from synchronous rotation to the first friction wheel 10 continuing to rotate while the second friction wheel 11 remains stationary), four clamping plates 15 can clamp and limit ore samples of different sizes, ensuring the stability of the ore samples during subsequent testing (the principle is the same when the first and last clamping plates 15 first contact the ore sample); when the second rotating rod 9 on the right rotates, it will drive the second belt 16, the third rotating rod 17, the first bevel gear 18, the second bevel gear 19, and the second threaded rod 20 to rotate, causing the second hollow rod 21 and the anti-rotation mechanism to rotate. The following components move downwards: 22 (disassembly block), 24 (fixed plate), 25 (first T-shaped rod), 26 (moving plate), 30 (second T-shaped rod), 28 (slider), 31 (pressure sensor), 32 (mounting plate), and 33 (detection head). The detection head 33 continues to move downwards as the second rotating rod 9 continues to rotate. The pressure sensor 31 displays the pressure value in real-time on the control panel 34 until the detection head 33 breaks the clamped ore sample. The force value of the ore sample can then be obtained from the display screen.

[0039] After the test is completed, the motor 2 is started to rotate its output shaft in reverse, causing the four clamping plates 15 to move in opposite directions, which can release the ore sample and move the detection head 33 upward, separating it from the ore sample. The operator holds the first T-shaped rod 25 and rotates it to move the moving plate 26, the first connecting block 27, the slider 28, the second connecting block 29, the second T-shaped rod 30, the pressure sensor 31, the mounting plate 32, and the detection head 33 left and right, which can adjust the detection head 33 in the X-axis direction. The operator holds the second T-shaped rod 30 and rotates it to move the slider 28, the second connecting block 29, the pressure sensor 31, the mounting plate 32, and the detection head 33 back and forth, which can adjust the detection head 33 in the Y-axis direction. By adjusting the detection head 33 in the X and Y axes, ore samples at different positions can be tested, with a wide testing range.

[0040] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be covered within the protection scope of the present utility model.
