Description

Technical Field

[0001] The present invention belongs to the field of geological detection technology, and in particular relates to a geological engineering sample detection device and method. Background Art

[0002] Geological engineering is a science that studies geological problems and uses engineering methods to solve them. When conducting geological research, samples need to be taken out from underground and tested. Currently, when in use, the sampling height of the barrel is adjusted by rotating the adjusting screw to push the barrel and the guide rings on both sides to slide along the guide rod. The drive motor drives the auger blades at the bottom to rotate for sampling. The sample stays in the barrel. After sampling, it is tested using professional equipment.

[0029] The present invention also provides a method for a geological engineering sample detection device as described above, including the following steps:

[0030] Step S1, adjustment of the floating adjustment mechanism:

[0031] When the device moves on different geological landforms, the movement attitude of the device is monitored in real time through the installed level gauge, and the result is transmitted to the controller; the controller controls the elongation of multiple movable rods to ensure that the bottom plate remains horizontal;

[0032] Step S2, the vertical guiding mechanism adjusts the position of the cylinder in the height direction to lower the cylinder for sampling:

[0033] Initially, the ejecting piece of the plugging mechanism is inside the cylinder near the bottom sampling port and is in a gathered state;

[0034] The double-layer gear ring is driven by an external motor.

[0037] Continue to drive the cylinder body to descend, and use the set ejector piece to eject the sample in the cylinder body. At the same time, when the driving gear shaft rotates, it can push the single-sided toothed plate and the triangular plate to slide along the vertical rod. The free end of the triangular plate intercepts the sample ejected from the top of the cylinder body. The intercepted sample falls on the upper surface of the triangular plate and moves along the upper surface of the triangular plate and finally falls on the receiving plate;

[0038] Step S4, the horizontal driving mechanism drives the sample on the receiving plate to rotate to the detection position:

[0039] At the same time, when the double-layer toothed ring rotates, it drives the driving gear shaft and the driven gear shaft to rotate in sequence.

Detailed implementation manners

[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0049] As Figures 1-5 shown, a structural diagram of a geological engineering sample detection device provided by an embodiment of the present invention includes a bottom plate 1, a cylinder 10, a floating adjustment mechanism 100, a vertical guiding mechanism 200, a plugging mechanism 300, a horizontal driving mechanism 400, and an elastic cutting mechanism 500.

[0050] The floating adjustment mechanism 100 is installed on the bottom plate 1 and is used to adapt to the surfaces of various geological formations; the vertical guiding mechanism 200 is arranged on the double-layer gear ring 9 at the top of the bottom plate 1 and is connected to the cylinder 10 to facilitate adjusting the position of the cylinder 10 in the height direction; the plugging mechanism 300 is arranged inside the cylinder 10 and cooperates with the plugging mechanism 300 to perform sampling work when the cylinder 10 is lifted and lowered; the horizontal driving mechanism 400 is arranged on the second bracket 22 installed on the upper surface of the bottom plate 1. The second bracket 22 is composed of a longitudinal rod and a triangular plate, and the triangular plate is slidably connected to the longitudinal rod. The horizontal driving mechanism 400 is in transmission connection with the double-layer gear ring 9 and is used to adjust the position of the sample in the horizontal plane; the elastic cutting mechanism 500 is in transmission connection with the driving gear shaft 24 in the horizontal driving mechanism 400 to facilitate cutting the sample at the top end of the cylinder 10; wherein, a support frame 32 is fixedly installed on the bottom plate 1, and a detection module 33 is installed at the top end of the support frame 32 and is used to detect the sample rotated to the position of the support frame 32.

[0051] In an example of the present invention, a pair of side rods 7 are further installed on the side surface of the bottom plate 1, a push rod 8 is installed on one side of the side rod 7 opposite to each other, and a protective sleeve is adhered to the surface of the push rod 8 to increase the static friction force during pushing.

[0052] As Figure 1 shown, as a preferred embodiment of the present invention, the floating adjustment mechanism 100 includes a fixed rod 2, a movable rod 3, a wheel 4, a level 5 and a controller 6;

[0053] A plurality of fixed rods 2 are provided, the fixed rods 2 are equidistantly installed on the bottom surface of the bottom plate 1, the movable rod 3 is floatingly installed on the fixed rod 2, and the wheel 4 is rotatably installed on the side surface of the movable rod 3;

[0054] Both the level 5 and the controller 6 are installed on the upper surface of the bottom plate 1, and the level 5 and the controller 6 are electrically connected.

[0055] In an example of the present invention, when the device moves on different geological landforms, the level 5 provided is used to monitor the movement posture of the device in real time, and the result is transmitted to the controller 6, and the controller 6 controls the elongation of a plurality of movable rods 3 to ensure that the bottom plate 1 maintains a horizontal state.

[0056] As Figure 1 and Figure 2 shown, as another preferred embodiment of the present invention, the vertical guiding mechanism 200 includes a horizontal rod 11, an elastic support member 12, a gear shaft 13, a support 14, a lever 15 and a lever 16;

[0057] The horizontal rod 11 is arranged inside the adjacent cylinders 10, and the horizontal rod 11 is connected to the elastic support member 12 installed on the upper surface of the bottom plate 1;

[0058] The support 14 is installed on the bottom plate 1, and a gear shaft 13 meshing with the inner side of the double-layer gear ring 9 is installed at the free end of the support 14;

[0059] A lever 15 is installed at the end of the gear shaft 13, and the lever 15 abuts against the lever 16 installed on the side surface of the cylinder 10 in a rotating state.

[0060] In an example of the present invention, the shape of the first support 14 is adjusted as needed to facilitate bypassing the double-layer gear ring 9 and connecting to the bottom plate 1. The double-layer gear ring 9 is driven by an external motor. Since the double-layer gear ring 9 meshes with the gear shaft 13, it can drive the gear shaft 13 and the first lever 15 to rotate along the first support 14. The first lever 15 in the rotating state pushes the second lever 16 and the cylinder 10 to slide along the bottom plate 1, and the first elastic support member 12 is elastically deformed under force; in addition, in this application, the transmission process between the first lever 15 and the second lever 16 can also be replaced by a transmission method of a gear and a toothed plate.

[0061] As Figure 1 and Figure 3 shown, as another preferred embodiment of the present invention, the plugging mechanism 300 includes a top plate 17, a double-headed telescopic member 18, a pull rod 19, a first longitudinal rod 20, and an ejecting piece 21;

[0062] The top plate 17 is arranged at the top of the cylinder 10, and a first longitudinal rod 20 arranged coaxially with the cylinder 10 is installed on the bottom surface of the top plate 17;

[0063] The double-headed telescopic member 18 is installed on the upper surface of the top plate 17. Pull rods 19 are installed at both ends of the double-headed telescopic member 18. The pull rods 19 are connected to the ejecting piece 21 installed at the end of the first longitudinal rod 20 for pushing the ejecting piece 21 to expand along the first longitudinal rod 20.

[0064] In an example of the present invention, during the descending process of the cylinder 10, the ejecting piece 21 stays in the first longitudinal rod 20 and is in a non-expanded state. When the sampling of the cylinder 10 during its descent ends, the double-headed telescopic member 18 expands the ejecting piece 21 through the arranged pull rods 19. The free end of the ejecting piece 21 abuts against the inner wall of the cylinder 10, and the sample inside the cylinder 10 is ejected by using the arranged ejecting piece 21 when the cylinder 10 descends.

[0065] As Figure 1 and Figure 4 shown, as another preferred embodiment of the present invention, the horizontal driving mechanism 400 includes a fixed ring 23, a driving gear shaft 24, a driven gear shaft 25, a receiving plate 26, and a diagonal strut 27;

[0066] The fixed ring 23 is installed on the longitudinal rod in the second support 22. The receiving plate 26 and the diagonal strut 27 are rotatably installed on the fixed ring 23, and a gear ring is arranged inside the receiving plate 26;

[0067] The driving gear shaft 24 and the driven gear shaft 25 are both rotatably installed on the bottom plate 1. The driving gear shaft 24 meshes with the double-layer gear ring 9, the driving gear shaft 24 meshes with the driven gear shaft 25, and the driven gear shaft 25 meshes with the gear ring inside the receiving plate 26.

[0068] In an example of the present invention, when the double-layer gear ring 9 rotates, it drives the driving gear shaft 24 and the driven gear shaft 25 to rotate in sequence. The driven gear shaft 25 drives the gear ring inside the material receiving plate 26 to rotate, thereby pushing the material receiving plate 26 and the diagonal strut 27 to slide along the fixed ring 23, transferring the sample falling on the upper surface of the material receiving plate 26 in the horizontal plane. When it rotates to the rightmost side, it is detected by the arranged detection module 33.

[0069] As Figure 1 and Figure 5 shown, as another preferred embodiment of the present invention, the elastic intercepting mechanism 500 includes an incomplete gear 28, a single-sided tooth plate 29, a longitudinal rod II 30, and an elastic support II 31;

[0070] The incomplete gear 28 is fixedly installed at the top of the driving gear shaft 24, and the incomplete gear 28 meshes with the single-sided tooth plate 29 installed inside the triangular plate;

[0071] The end of the single-sided tooth plate 29 is installed with a longitudinal rod II 30, and the longitudinal rod II 30 is connected to the elastic support II 31 installed on the side of the longitudinal rod.

[0072] In an example of the present invention, when the driving gear shaft 24 rotates, since the incomplete gear 28 meshes with the single-sided tooth plate 29, it can push the single-sided tooth plate 29 and the triangular plate to slide along the longitudinal rod. The elastic support II 31 is elastically deformed under force, and the free end of the triangular plate intercepts the sample ejected from the top of the cylinder 10. The intercepted sample falls on the upper surface of the triangular plate and moves along the upper surface of the triangular plate.

[0073] The present invention also provides a method for a geological engineering sample detection device, including the following steps:

[0074] Step S1, adjustment of the floating adjustment mechanism:

[0075] When the device moves on different geological landforms, the attitude of the device during movement is monitored in real time by the provided spirit level, and the result is transmitted to the controller; the controller controls the elongation of multiple movable rods to ensure that the bottom plate remains horizontal;

[0076] Step S2, the vertical guiding mechanism adjusts the position of the cylinder in the height direction to lower the cylinder for sampling:

[0077] Initially, the ejecting piece of the plugging mechanism is inside the cylinder near the bottom sampling port and is in a gathered state;

[0078] The double-layer gear ring is driven by an external motor. Since the double-layer gear ring meshes with the gear shaft, it drives the gear shaft and the first lever to rotate along the first bracket. The first lever in the rotating state pushes the second lever and the cylinder body to slide along the bottom plate, and the cylinder body descends for sampling;

[0079] Step S3, the plugging mechanism and the elastic intercepting mechanism cooperate to intercept the sample at the top of the cylinder body:

[0080] After the cylinder body descends and the sampling is completed, the double-headed telescopic part of the plugging mechanism unfolds the ejecting piece through the arranged pull rod, and the free end of the ejecting piece abuts against the inner wall of the cylinder body;

[0081] Continue to drive the cylinder body to descend, use the arranged ejecting piece to eject the sample in the cylinder body. At the same time, when driving the gear shaft to rotate, it can push the single-sided tooth plate and the triangular plate to slide along the vertical rod. The free end of the triangular plate intercepts the sample ejected from the top of the cylinder body. The intercepted sample falls on the upper surface of the triangular plate and moves along the upper surface of the triangular plate and finally falls on the receiving plate;

[0082] Step S4, the horizontal driving mechanism drives the sample on the receiving plate to rotate to the detection position:

[0083] At the same time, when the double-layer gear ring rotates, it drives the driving gear shaft and the driven gear shaft to rotate in sequence. The driven gear shaft drives the gear ring to rotate, and then pushes the receiving plate and the diagonal strut to slide along the fixed ring, transfers the sample on the upper surface of the receiving plate in the horizontal plane. When it rotates to the rightmost side, it is detected by the arranged detection module.

[0084] In summary, when the device moves on different geological landforms, the spirit level 5 is provided to monitor the movement attitude of the device in real time, and the result is transmitted to the controller 6. The controller 6 controls the elongation of multiple movable rods 3 to ensure that the bottom plate 1 remains horizontal. The double-layer gear ring 9 is driven by an external motor. Since the double-layer gear ring 9 meshes with the gear shaft 13, it can drive the gear shaft 13 and the first shift lever 15 to rotate along the first bracket 14. The first shift lever 15 in the rotating state pushes the second shift lever 16 and the cylinder 10 to slide along the bottom plate 1, and the cylinder 10 descends for sampling. The first elastic support member 12 undergoes elastic deformation under force. After the cylinder 10 finishes descending for sampling, the double-headed telescopic member 18 unfolds the ejector piece 21 through the arranged pull rod 19. The free end of the ejector piece 21 abuts against the inner wall of the cylinder 10. When the cylinder 10 descends, the sample in the cylinder 10 is ejected by the arranged ejector piece 21. When the driving gear shaft 24 rotates, it can push the single-sided toothed plate 29 and the triangular plate to slide along the longitudinal rod. The free end of the triangular plate intercepts the sample ejected from the top of the cylinder 10. The intercepted sample falls on the upper surface of the triangular plate and moves along the upper surface of the triangular plate and finally falls on the receiving plate 26. At the same time, when the double-layer gear ring 9 rotates, it drives the driving gear shaft 24 and the driven gear shaft 25 to rotate in sequence. The driven gear shaft 25 drives the gear ring to rotate, thereby pushing the receiving plate 26 and the diagonal strut 27 to slide along the fixed ring 23 to transfer the sample on the upper surface of the receiving plate 26 in the horizontal plane. When it rotates to the rightmost side, it is detected by the arranged detection module 33. This detection device can be used on different geological landforms, has the characteristics of high adaptability, and has more sampling positions, which can avoid the problem of affecting the detection data by sampling at a single position. It can automatically eject the sampled sample to prevent blockage, and can also automatically transfer the sample for detection, which can ensure the detection accuracy to the greatest extent.

The intercepted sample falls on the upper surface of the triangular plate and moves along the upper surface of the triangular plate and finally falls on the receiving plate; Step S4, the horizontal driving mechanism drives the sample on the receiving plate to rotate to the detection position: At the same time, when the double-layer gear ring rotates, it drives the driving gear shaft and the driven gear shaft to rotate in sequence. The driven gear shaft drives the gear ring to rotate, and then pushes the receiving plate and the diagonal strut to slide along the fixed ring, transfers the sample on the upper surface of the receiving plate in the horizontal plane. When it rotates to the rightmost side, it is detected by the arranged detection module.
