Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of geotechnical engineering detection, and in particular to a geotechnical sampling and identification device. Background Art
[0002] A geotechnical sampling and identification device is a specialized device used to collect, process, and analyze geotechnical samples to determine their physical, mechanical, or chemical properties. These devices are commonly used in geological exploration, civil engineering, and environmental monitoring, helping engineers and scientists understand key parameters such as the composition, strength, and permeability of geotechnical layers.
[0003] However, the actual terrain of the sampling site is often complex and diverse, and the ground is often uneven. When facing uneven ground, traditional geotechnical sampling devices are difficult to ensure that the sampling device is in a stable state. A current geotechnical sampling and identification device generally has a flat-bottomed triangular bracket at the bottom, which is used to abut the ground. However, when the ground is uneven, the triangular bracket will shake left and right during operation, resulting in an unstable working state of the geotechnical sampling and identification device. Summary of the Invention
[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a rock and soil sampling and identification device that can perform stable operations on uneven ground.
[0005] The purpose of the present invention is achieved by adopting the following technical solutions:
[0006] A rock and soil sampling and identification device comprises: a horizontal adjustment mechanism, a lifting drive mechanism and a rock and soil core sampling device; the horizontal adjustment mechanism comprises a support frame and a plurality of support rods; the support rods are distributed at intervals along the horizontal direction, and each of the support rods can be movably connected to the support frame so as to be able to be lifted and lowered relative to the support frame; the support rods are used to abut the ground to support the support frame; the lifting drive mechanism is installed on the support frame; the rock and soil core sampling device is installed on the output part of the lifting drive mechanism.
[0007] Furthermore, the bottom of the support frame is a grounding plate, which is used to abut the ground; the middle of the support frame has a suspension frame, which is located above the grounding plate, and the support rod is installed on the suspension frame and is used to support the suspension frame.
[0008] Furthermore, the suspension frame and the grounding plate are spaced apart to form an isolation distance therebetween, and the isolation distance is used to accommodate the bottom of the support rod.
[0009] Furthermore, the support rod is a threaded rod, the suspension frame is provided with a threaded hole, and the threaded rod is threadedly connected to the threaded hole.
[0010] Furthermore, the bottom of the support rod is connected to a support base plate, and the horizontal projection area of the support base plate is larger than the horizontal cross-sectional area of the support rod.
[0011] Furthermore, the support frame supports one or more vertical guide rods, and the rock and soil core sampling device is movably connected to the vertical guide rods.
[0012] Furthermore, the vertical guide rod is arranged on the suspension frame.
[0013] Furthermore, the grounding plate is detachably connected to the suspension frame.
[0014] Furthermore, the bottom of the suspension frame extends downward to form a distance tube, and there are multiple distance tubes, and the multiple distance tubes are arranged at intervals in the horizontal direction; the grounding plate has an insertion rod, and there are multiple insertion rods, and the multiple insertion rods are respectively inserted into one of the distance tubes.
[0015] Furthermore, a top plate is provided on the top of the support frame, and the lifting drive mechanism is installed at the bottom of the top plate; the support frame is provided with an angle scale, and the angle scale is pivotally connected to a vertical identification rod, and the vertical identification rod is arranged on the horizontal side of the angle scale.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. Because support rods 12 are spaced horizontally and each support rod 12 is movably connected to support frame 11 so as to be capable of being raised and lowered relative to support frame 11, the multiple elevating support rods 12 of horizontal adjustment mechanism 1 can be used to quickly and accurately adjust support frame 11 to a stable position under varying terrain conditions. This stable support provides a solid foundation for the elevating drive mechanism 2 and the rock and soil core sampling device 3, preventing sampling deviations caused by device tilt, thereby significantly improving the accuracy and stability of rock and soil sampling and ensuring that the samples obtained are more representative.
[0018] 2. The lifting drive mechanism 2 precisely controls the descent depth and speed of the rock core sampling device 3 based on the actual rock and soil conditions. This precise control not only adapts to the sampling needs of rock and soil with varying hardness and structure, but also effectively avoids over-drilling or under-drilling. Furthermore, the flexible lifting and lowering operation enables the device to better cope with complex working conditions during the sampling process, improving sampling efficiency and success rate.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] See also Figure 1-Figure 3 A preferred embodiment of the present invention is a rock and soil sampling and identification device, comprising: a horizontal adjustment mechanism 1, a lifting drive mechanism 2 and a rock and soil core sampling device 3; the horizontal adjustment mechanism 1 comprises a support frame 11 and a plurality of support rods 12; each of the support rods 12 is distributed at intervals along the horizontal direction, and each of the support rods 12 can be movably connected to the support frame 11 so as to be able to be lifted and lowered relative to the support frame 11; the support rods 12 are used to abut the ground to support the support frame 11; the lifting drive mechanism 2 is installed on the support frame 11; the rock and soil core sampling device 3 is installed on the output part of the lifting drive mechanism 2.
[0027] When conducting rock and soil sampling and identification, the rock and soil sampling and identification device is first moved to the target sampling location. Because the support rods 12 are spaced horizontally and each support rod 12 is movably connected to the support frame 11, allowing it to be raised and lowered relative to the support frame 11, the multiple elevating support rods 12 of the horizontal adjustment mechanism 1 can quickly and precisely adjust the support frame 11 to a stable position under varying terrain conditions. This stable support provides a solid foundation for the lifting drive mechanism 2 and the rock and soil core sampling device 3, preventing sampling deviations caused by device tilt. This significantly improves the accuracy and stability of rock and soil sampling and ensures a more representative sample. The lifting drive mechanism 2 precisely controls the descent depth and speed of the rock and soil core sampling device 3 based on the actual rock and soil conditions. This precise control not only adapts to the sampling needs of rock and soil with varying hardness and structure, but also effectively avoids over-drilling or under-drilling. Furthermore, the flexible lifting and lowering operation enables the device to better cope with complex working conditions during the sampling process, improving sampling efficiency and success rate.
[0028] Preferably, in this embodiment, the bottom of the support frame 11 is a grounding plate 111, which is used to contact the ground. A suspension frame 112 is located in the middle of the support frame 11, positioned above the grounding plate 111. The support rod 12 is mounted on the suspension frame 112 and supports the suspension frame 112. This arrangement allows the grounding plate 111 at the bottom of the support frame 11 to directly contact the ground, increasing the contact area between the device and the ground, reducing the pressure per unit area, and making the device less likely to tip over. The suspension frame 112 is located above the grounding plate 111 and supported by the support rod 12 mounted on the suspension frame 112. This layered structural design forms a stable support system. The grounding plate 111 provides the foundational support, while the suspension frame 112 and support rod 12 are further stabilized through their adjustable height. The combination of the two effectively distributes the load generated during operation, ensuring the device remains stable during soil sampling and further improving sampling accuracy. The geotechnical sampling and identification device works on a flat ground in most cases, so the grounding plate 111 will frequently touch the ground. Only occasionally will it work on an uneven ground and then the support rod 12 will touch the ground to adjust the support frame 11 to be stable.
[0029] Preferably, in this embodiment, the suspension frame 112 and the grounding plate 111 are spaced apart to form an isolation distance therebetween, and the isolation distance is used to accommodate the bottom of the support rod 12. In this way, the isolation distance between the suspension frame 112 and the grounding plate 111 provides an exclusive accommodation space for the bottom of the support rod 12. When the geotechnical sampling and identification device is working on a flat ground or during transportation, the bottom of the support rod 12 can be accommodated in the isolation distance to prevent the support rod 12 from being damaged by external collisions and scratches, thereby effectively extending its service life. At the same time, such accommodation can also prevent the support rod 12 from shaking arbitrarily during movement, ensuring that the overall structure of the device is compact and easy to carry and store.
[0030] Preferably, in this embodiment, the support rod 12 is a threaded rod, the suspension frame 112 is provided with a threaded hole 1122, and the threaded rod is threadedly connected to the threaded hole 1122. In this way, the support rod 12 is set as a threaded rod and is threadedly connected to the threaded hole 1122 on the suspension frame 112. By rotating the threaded rod, fine adjustment of the height of the support rod 12 can be achieved. The threaded structure of the threaded rod enables each rotation to bring about precise displacement changes. The staff can gradually fine-tune the height of the support rod 12 according to the actual horizontal situation of the support frame 11 until the support frame 11 reaches the ideal horizontal and stable state. Compared with other adjustment structures, this precise adjustment method can better adapt to the complex and changeable ground environment, ensure that the geotechnical sampling and identification device always maintains a horizontal and stable state during operation, and provide reliable protection for accurate sampling.
[0031] Preferably, in this embodiment, the bottom of the support rod 12 is connected to a support base plate 121, and the horizontal projection area of the support base plate 121 is larger than the horizontal cross-sectional area of the support rod 12. With this arrangement, the horizontal projection area of the support base plate 121 connected to the bottom of the support rod 12 is larger than the horizontal cross-sectional area of the support rod 12 itself, thereby increasing the contact area with the ground. A larger contact area can effectively reduce the pressure per unit area, making it less likely for the device to tilt, sink or slide when placed on the ground. Whether it is soft soil, sand, or uneven rocky ground, the support base plate 121 can provide a more stable support foundation, ensuring that the entire rock and soil sampling and identification device remains stable during operation, thereby ensuring the accuracy of rock and soil sampling.
[0032] Preferably, in this embodiment, the support frame 11 supports one or more vertical guide rods 113, and the rock and soil core sampling device 3 is movably connected to the vertical guide rods 113. With this arrangement, the vertical guide rods 113 supported by the support frame 11 provide a precise motion track for the rock and soil core sampling device 3. The rock and soil core sampling device 3 is movably connected to the vertical guide rods 113. During the lifting and lowering process driven by the lifting drive mechanism 2, the vertical guide rods 113 can effectively limit the lateral displacement of the sampling device, so that it can only move in a straight line along the vertical direction. This ensures that the rock and soil core sampling device 3 always maintains a vertical downward motion trajectory during drilling sampling, avoids sampling deviations caused by offset, greatly improves the collection accuracy of rock and soil samples, and enables the obtained samples to more truly reflect the rock and soil characteristics of the target location.
[0033] Preferably, in this embodiment, the vertical guide rod 113 is mounted on the suspension frame 112. This arrangement allows the vertical guide rod 113 to be directly attached to the suspension frame 112, enabling faster and more accurate transmission of the adjustment effects of the suspension frame 112 to the rock core sampling device 3. Once the suspension frame 112 is adjusted to a stable state via the horizontal adjustment mechanism 1, the vertical guide rod 113 ensures that the rock core sampling device 3 remains horizontal and stable, using a shorter transmission path. This reduces the accumulation of errors caused by excessive intermediate links, enhances the collaborative working ability of various components, and further improves the accuracy and efficiency of rock core sampling.
[0034] Preferably, in this embodiment, the grounding plate 111 is detachably connected to the suspension frame 112. This arrangement and the detachable connection greatly simplify the maintenance process of the device. When the grounding plate 111 becomes worn, damaged, or requires cleaning, the staff does not need to perform a complex disassembly of the entire device. They only need to remove the grounding plate 111 from the suspension frame 112 to quickly perform repair, replacement, or cleaning operations. At the same time, this design also facilitates inspection of the connection between the suspension frame 112 and the grounding plate 111, allowing for the timely detection and treatment of potential looseness, rust, and other problems, effectively reducing the difficulty and time cost of maintenance and ensuring the long-term stable operation of the device.
[0035] Preferably, in this embodiment, the bottom of the suspension frame 112 extends downward to form a spacer tube 1121. Multiple spacer tubes 1121 are provided, spaced horizontally apart. The grounding plate 111 includes multiple insertion rods 1111, each inserted into one of the spacer tubes 1121. This arrangement allows the spacer tubes 1121 at the bottom of the suspension frame 112 to cooperate with the insertion rods 1111 of the grounding plate 111, enabling precise positioning during installation. Multiple insertion rods 1111 are inserted into corresponding spacer tubes 1121, ensuring accurate horizontal and vertical alignment between the grounding plate 111 and the suspension frame 112, thus preventing installation deviations. The staff only needs to align the insertion rod 1111 with the distance cylinder 1121 and insert it to quickly complete the installation of the grounding plate 111 and the suspension frame 112. There is no need for a complicated calibration process, which greatly improves the assembly efficiency of the device and is especially suitable for work scenarios that require frequent disassembly and assembly.
[0036] Preferably, in this embodiment, a top plate 114 is provided on the top of the support frame 11, and the lifting drive mechanism 2 is mounted on the bottom of the top plate 114. The support frame 11 is also provided with an angle scale 115, which is pivotally connected to a vertical identification rod 116, which is disposed on the horizontal side of the angle scale 115. The top plate 114 provided on the top of the support frame 11 provides a stable mounting base for the lifting drive mechanism 2, ensuring its stability during operation. The combination of the angle scale 115 and the vertical identification rod 116 can intuitively and accurately assist personnel in determining the horizontal state of the support frame 11. When adjusting the horizontal adjustment mechanism 1, personnel can quickly obtain information on the tilt angle of the support frame 11 by observing the relative position of the vertical identification rod 116 and the angle scale 115, and promptly adjust the height of the support rod 12, avoiding repeated trial and error. This significantly improves the accuracy and efficiency of horizontal adjustment, ensures that the rock core sampling device 3 is in a horizontal and stable working state, and enhances sampling accuracy. The lifting drive mechanism 2 can be a pneumatic lifting rod lifting or an electric lifting rod lifting.
