Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a geological survey rock and soil hardness detection device. Background Art

[0002] In fields such as geological engineering, civil engineering, and environmental engineering, the properties and behavior of rock and soil have a significant impact on engineering design and construction. Geotechnical engineering involves the study of the mechanical and physical properties of rock and soil, as well as their behavior under varying environmental conditions. Geological surveys involve obtaining geological data through a series of geological surveys, tests, and analyses to understand the geological characteristics and conditions of a region or site.

[0003] Geological surveys play a vital role in civil engineering, mining, environmental protection, urban planning, and other fields. Through on-site observation, sampling, and measurement, we understand surface and underground geological conditions, including rock and soil types, structural characteristics, and stratum distribution. The results of geological surveys are crucial for every stage of a project, from site selection and design to construction and operation and maintenance. They help engineers identify potential geological risks and develop appropriate engineering plans, thereby improving project safety and cost-effectiveness.

[0004] For example, in the existing Chinese patent publication number CN217132759U, a rock and soil strength testing device for road engineering geological surveys is disclosed. Using this prior art, driven by an electric push rod, a first rack moves downward, driving two gears to rotate. The rotation of the two gears drives two second racks upward. Because a baffle is fixedly connected to the bottom of the second rack, the upward movement of the second rack drives the baffle upward, allowing the baffle to cover the outside of the support plate, thereby preventing rock from splashing during hardness testing.

[0005] However, the above-mentioned prior art has the following technical defects: When the above device is in use, the rock to be tested is placed on the support plate, and the electric push rod is activated to drive the pressure plate downward, while also driving the two cross bars downward. Under the meshing action of the first rack and the gear, the two second racks are driven upward, which in turn drives the baffle upward so that the baffle covers the outside of the support plate to prevent the rock from splashing when the hardness test is performed on the rock. During testing, the pressure plate is mainly driven downward by the electric push rod, so that the pressure plate acts on the rock on the support plate to test the rock's strength. However, the final hardness of the rock detected is unknown, and the test information cannot be intuitively reflected, which means that the staff cannot record the rock's strength data.

[0006] Secondly, the above-mentioned prior art needle cannot adjust the rock strength to be tested. The strength of rocks in different regions and types varies. During testing, the above-mentioned equipment only uses a single electric push rod to drive the pressure plate downward so that it presses on the rock for testing. However, the driving force of the electric push rod and the travel of the driving plate are ultimately limited. When the rock is strong enough to withstand the ultimate thrust of the electric push rod, it cannot be tested. Therefore, the applicability of the above-mentioned device is poor and it has significant limitations.

[0007] Based on this, on the basis of the existing rock and soil strength detection device for road engineering geological survey, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the Invention

[0008] In order to be able to test the hardness of the rock and soil after sampling, and to display the test data in real time, and at the same time to adjust the test intensity to be suitable for rock and soil testing of different types and hardness, the present application provides a geological survey rock and soil hardness testing equipment.

[0009] This application provides a geological survey rock and soil hardness testing device, which adopts the following technical solutions: A geological survey rock and soil hardness testing device comprises a testing platform and an L-shaped rod base mounted on one side of the testing platform, wherein two frame bases are symmetrically arranged on the testing platform, and a testing device is provided on the testing platform; The detection device includes a through-hole cylinder vertically installed between two frame bases through a horizontal hanging rod, an inner round rod is slidably inserted into the through-hole cylinder, and the upper end of the inner round rod is connected to a rectangular tray, and rectangular side rods for limiting the rectangular tray are vertically installed on the two frame bases through push rods; The through-hole cylinder is provided with a strength adjusting piece, the L-shaped rod seat is provided with a presser, and the detection table below the through-hole cylinder is provided with a reflection component for displaying detection data.

[0010] Preferably, the strength adjustment member includes a cylindrical seat sleeved on the through-hole cylinder, and the cylindrical seat has a through hole adapted to the inner rod, and a push spring is sleeved on the inner rod between the cylindrical seat and the rectangular tray.

[0011] Preferably, the through-hole cylinder has a threaded connection portion, the inner side of the cylindrical seat is provided with an internal thread adapted to the threaded connection portion, and the cylindrical seat and the through-hole cylinder are threadedly connected.

[0012] Preferably, the presser includes a driving cylinder with its telescopic end downwardly mounted at an L-shaped rod seat, and a pressing plate is provided at the telescopic end of the driving cylinder, and the pressing plate is located directly above the rectangular tray.

[0013] Preferably, the reflection component includes an indicator rod seat vertically installed on the detection platform and located between the two frame bases. The indicator rod seat is provided with a bottom cross bar that slides up and down through a T-shaped block, and the bottom cross bar is located directly below the through-hole cylinder. The indicator rod seat is provided with a vertical sliding groove for the T-shaped block to limit the sliding.

[0014] Preferably, a pressing elastic sheet is embedded in one side of the T-shaped block, and the pressing elastic sheet contacts the inner wall of the vertical sliding groove, and a rectangular groove for installing the pressing elastic sheet is opened on the T-shaped block.

[0015] Preferably, the outer side of the indicator rod seat has an indicating scale.

[0016] Preferably, the lower pressing plate is made of a metal material with high hardness and not easy to deform.

[0017] Preferably, the lower pressing plate is rectangular and has dimensions smaller than the inner dimensions of the rectangular tray.

[0018] Preferably, the upper end of the rectangular side rod has a protrusion extending toward the rectangular tray.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the rock and soil to be tested in a rectangular tray, then start the driving cylinder to push the lower pressure plate downward to act on the rock and soil. Under the action of the push spring, the rectangular tray and the inner rod will move downward to different degrees according to the hardness of the rock and soil. When the inner rod moves downward and extends out of the through-hole cylinder, it will push the bottom cross bar down until the rock and soil are broken. The final position of the bottom cross bar is the hardness data obtained from this rock and soil test.

[0020] 2. According to the different hardness of the rock and soil to be tested, the strength of the push spring can be adjusted accordingly. Specifically, when the rotating cylindrical seat moves upward, the push spring will be compressed, and it can be used to detect rock and soil with higher hardness; similarly, when the rotating cylindrical seat moves downward, the push spring will expand, and it can be used to detect rock and soil with lower hardness, thus realizing the detection of rock and soil with different hardness.

[0021] 3. A tightening spring piece is provided on one side of the T-shaped block, which contacts the inner wall of the vertical slide. When the inner round rod moves downward and pushes the bottom cross bar down, under the action of the tightening spring piece, the bottom cross bar can automatically hover at the current position when the inner round rod does not contact the bottom cross bar, so that the staff can pass through the hovering position and record the detection data according to the indication scale.

[0034] The following is combined with Figures 1-11 This application is described in further detail.

[0035] The embodiment of the present application discloses a geological survey rock and soil hardness testing device, which can perform hardness testing on sampled rock and soil, and can display the test data in real time. At the same time, the test intensity can be adjusted to be suitable for rock and soil testing of different types and hardness.

[0036] Example 1: Reference Figure 1 and Figure 2 As shown, the present application provides a geological survey rock and soil hardness testing equipment, including a testing platform 1 and an L-shaped rod seat 11 installed on one side of the testing platform 1, two frame bases 12 are symmetrically arranged on the testing platform 1, and a testing device 2 is provided on the testing platform 1; it is used to perform hardness testing on the rock and soil after sampling, and can be suitable for rock and soil testing work of different hardness.

[0037] The detection device 2 includes a through-hole cylinder 22 vertically mounted between the two frame bases 12 via a horizontal hanging rod 21. The horizontal hanging rod 21 is fixedly connected to the two frame bases 12, while the through-hole cylinder 22 is fixedly inserted into the middle of the horizontal hanging rod 21. An inner round rod 23 is slidably inserted into the through-hole cylinder 22, and a rectangular tray 24 is connected to the upper end of the inner round rod 23. The rectangular tray 24 is fixedly mounted on the upper end of the inner round rod 23. Rectangular side rods 26 are vertically mounted on the two frame bases 12 via push rods 25 to limit the position of the rectangular tray 24. The upper ends of the rectangular side rods 26 have raised portions 261 extending toward the rectangular tray 24. The raised portions 261 at the upper ends of the two rectangular side rods 26 limit the maximum position to which the rectangular tray 24 can rise. The highest position to which the rectangular tray 24 can rise is when the upper side of the rectangular tray 24 contacts the raised portions 261.

[0038] A strength adjustment member 3 is mounted on the through-hole cylinder 22, allowing the appropriate test intensity to be adjusted according to the hardness of the rock or soil being tested. A presser 4 is mounted on the L-shaped rod base 11, and a display assembly 5 for displaying test data is located on the testing platform 1 below the through-hole cylinder 22. During use, the sampled rock or soil is first placed in the rectangular tray 24. The strength adjustment member 3 is then used to adjust the appropriate test intensity. The presser 4 continuously applies downward pressure to the rock or soil until it breaks. Finally, the test data is visually displayed on the display assembly 5 for easy recording by the operator.

[0039] Reference Figure 3 and Figure 4Specifically, the strength adjustment member 3 includes a cylindrical seat 31 that is sleeved onto the through-hole cylinder 22. The cylindrical seat 31 has a through-hole 311 that is adapted to fit the inner rod 23, allowing the inner rod 23 to slide within the through-hole cylinder 22 and the cylindrical seat 31 when a driving force is applied. A push spring 32 is sleeved onto the inner rod 23 between the cylindrical seat 31 and the rectangular tray 24. The two ends of the push spring 32 respectively contact the upper side of the cylindrical seat 31 and the lower side of the rectangular tray 24. The push spring 32 always exerts a driving force to push the rectangular tray 24 upward. Under the action of the push spring 32, the upper side of the rectangular tray 24 always contacts the protrusion 261 at the upper end of the rectangular side rod 26. In other words, under normal conditions, the rectangular tray 24 is always in its highest position.

[0040] The through-hole cylinder 22 is provided with a threaded connection portion 33, and the inner side of the cylindrical seat 31 is provided with an internal thread 34 adapted to the threaded connection portion 33, and the cylindrical seat 31 and the through-hole cylinder 22 are threadedly connected. Rotating the cylindrical seat 31 can cause the cylindrical seat 31 to move upward or downward. When the hardness of the rock and soil to be tested is relatively high, the cylindrical seat 31 can be rotated to move it upward, so that the push spring 32 is compressed. As a result, when the down-presser 4 is in operation, it becomes more difficult to drive the rectangular tray 24 and the inner rod 23 downward, so that the rock and soil in the rectangular tray 24 will be subjected to stronger pressure to meet the conditions for testing rock and soil with higher hardness; on the other hand, it can also avoid the situation where the push spring 32 itself has a small elastic force, resulting in insufficient downward travel of the rectangular tray 24 and the inner rod 23 when encountering rock and soil with higher hardness.

[0041] When the hardness of the rock and soil is relatively low, the cylindrical seat 31 can be rotated downward to extend the push spring 32. Then, when the down-pressing device 4 is in operation, the pressure on the rock and soil can be reduced, thereby meeting the conditions for testing rock and soil with relatively low hardness, thereby further improving the applicability.

[0042] Reference Figure 5 As shown, in order to apply downward pressure to the rock and soil to be tested placed on the rectangular tray 24 to facilitate hardness testing, the down-pressing device 4 includes a driving cylinder 41 with its telescopic end downwardly mounted on the L-shaped rod seat 11. The telescopic end of the driving cylinder 41 is provided with a down-pressing plate 42, and the down-pressing plate 42 is located directly above the rectangular tray 24. The down-pressing plate 42 and the telescopic end of the driving cylinder 41 are fixedly connected. The down-pressing plate 42 is made of a metal material with high hardness and is not easily deformed. The down-pressing plate 42 is rectangular in shape and smaller than the internal dimensions of the rectangular tray 24.

[0043] Once the rock and soil are placed in the rectangular tray 24, the drive cylinder 41 is activated to push the lower pressure plate 42 downward to press against the rock and soil. Continued actuation of the drive cylinder 41 causes the rectangular tray 24 to move downward, and the lower end of the inner rod 23 extends downward beyond the through-hole cylinder 22. The harder the rock and soil, the more the inner rod 23 extends beyond the through-hole cylinder 22. Once the rock and soil are broken, the drive cylinder 41 is stopped, and the length of the inner rod 23 extending downward serves as the rock and soil hardness test data.

[0044] Reference Figure 6 and Figure 7 As shown, since the data during the test needs to be displayed in real time so that the staff can record the test data intuitively and clearly, the reflection component 5 includes an indicator rod seat 51 vertically mounted on the test platform 1 and located between the two frame bases 12. The indicator rod seat 51 is provided with a bottom crossbar 53 that slides up and down through a T-shaped block 52. The bottom crossbar 53 is located directly below the through-hole cylinder 22, and the bottom crossbar 53 and the T-shaped block 52 are fixedly connected. A vertical slide groove 511 is provided through the indicator rod seat 51 for the limited sliding of the T-shaped block 52. The outer side of the indicator rod seat 51 has an indicator scale 512. When the rock and soil are tested, when the lower end of the inner round rod 23 extends out of the through-hole cylinder 22, it will conflict with the bottom crossbar 53, thereby driving the bottom crossbar 53 to slide downward synchronously. With the help of the indicator scale 512, the staff can intuitively understand the hardness test data of the rock and soil.

[0045] Reference Figure 8 As shown, considering that after the rock and soil are damaged, when the inner rod 23 suddenly moves up and no longer conflicts with the bottom cross bar 53, the bottom cross bar 53 can automatically hover at the current position to ensure that the information of the detection is accurately displayed, a T-shaped block 52 is embedded with a spring clip 54 on one side, and the spring clip 54 conflicts with the inner wall of the vertical chute 511. A rectangular groove 521 is provided on the T-shaped block 52 for the installation of the spring clip 54. When detecting, first push the T-shaped block 52 and the bottom cross bar 53 to move up to the highest position, that is, let the bottom cross bar 53 conflict with the bottom end of the through-hole cylinder 22. When the lower end of the inner rod 23 stretches out and conflicts with the bottom cross bar 53, just can push the bottom cross bar 53 down in the first time. Until the rock and soil are broken, and at the moment of breaking, because the rock and soil volume becomes smaller, cause the inner rod 23 to suddenly move up, and the inner rod 23 at this moment can separate from the bottom cross bar 53, and the two no longer conflict. Under the action of the pressing spring piece 54, the bottom cross bar 53 will be suspended at the current height. By observing the indicator scale 512, the staff can accurately record the test data.

[0046] Example 2: Reference Figures 9 to 11As shown, based on the first embodiment, considering that after the rock and soil hardness test is completed, the rock and soil that has been crushed during the test can be quickly and conveniently removed, a placement component 6 is provided within the rectangular tray 24. The placement component 6 includes an inner tray 61 that is placed within the rectangular tray 24 and adapted to the inner dimensions of the rectangular tray 24. A magnet 1 62 is embedded in the bottom of the inner tray 61. The bottom of the inner tray 61 has a bottom groove 611 for mounting the magnet 1 62. A magnet 2 63 is embedded in the bottom of the rectangular tray 24, which attracts the magnet 1 62. The rectangular tray 24 has a circular groove 241 for mounting the magnet 2 63. External hanging blocks 64 are symmetrically provided on the inner tray 61 to facilitate removal of the inner tray 61 from the rectangular tray 24. Before placing the rock and soil, the inner tray 61 is first placed into the rectangular tray 24. The attraction between the magnet 1 62 and the magnet 2 63 can achieve the effect of locking the inner tray 61. Subsequently, during testing, the rock and soil can be placed in the inner tray 61. After the inspection is completed, the inner tray 61 can be quickly taken out from the rectangular tray 24 directly through the two external hanging blocks 64, so as to facilitate the removal of the broken rock and soil.

[0047] The implementation principle of this embodiment is: (1) Rock and soil placement: When in use, place the inner tray 61 into the rectangular tray 24. Under the attraction between magnet 1 62 and magnet 2 63, the inner tray 61 is stably locked in the rectangular tray 24. Then, the rock and soil that needs to be hardness tested is placed in the inner tray 61.

[0048] (2) Strength adjustment: According to the hardness of the rock and soil, the cylindrical seat 31 is rotated to drive it to move upward or downward; specifically, when the rock and soil is relatively soft and has a low hardness, the cylindrical seat 31 can be rotated to move it downward; otherwise, the cylindrical seat 31 can be rotated to move it upward.

[0049] (3) Downward pressure detection: Then start the driving cylinder 41 to push the lower pressure plate 42 down and press it against the rock and soil placed in the inner tray 61. As the driving cylinder 41 is driven, the rectangular tray 24 will move downward, causing the lower end of the inner circular rod 23 to extend downward from the through-hole cylinder 22 until the rock and soil are broken, and stop the driving cylinder 41.

[0050] (4) The data shows that when the lower end of the inner rod 23 extends out of the through-hole cylinder 22, it will contact the bottom crossbar 53, driving the bottom crossbar 53 to slide downward synchronously until the rock and soil are broken and the driving cylinder 41 stops operating. At this time, under the action of the pressing spring 54, the bottom crossbar 53 will hover at the current height, and the staff can accurately record the test data according to the indicator scale 512.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
