Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering investigation and geological exploration technology, specifically an adjustable drilling and sampling device for building geotechnical applications. Background Technology

[0002] In the field of geotechnical engineering investigation, drilling and sampling are crucial for obtaining geological information and ensuring the safety and economy of building foundation design. Currently, traditional drilling and sampling equipment has many limitations:

[0003] On the one hand, the support structure lacks adaptability. Most of the support components of the device are fixed structures, which are difficult to adapt to complex terrains such as slopes and uneven soft soil surfaces. This results in insufficient stability of the device during operation, making it prone to tilting or even overturning, which not only affects the sampling accuracy but also poses safety hazards.

[0004] On the other hand, the sampling components have poor adjustability. The length and diameter of the sampling tubes in existing devices are mostly fixed specifications, which cannot be flexibly adjusted according to the needs of different strata depths and soil types. If it is necessary to change the sampling depth or diameter, it is often necessary to disassemble the entire device and replace the core components, which is cumbersome and inefficient.

[0005] Furthermore, the accuracy of power transmission and positioning is insufficient. During drilling and sampling, the power transmission components of some devices are prone to misalignment, making it difficult to ensure the verticality of the drill bit and resulting in a high disturbance rate of the sample. At the same time, the locking structure between the support components and the main frame has poor reliability and is prone to loosening under the influence of operational vibrations, further reducing the stability and accuracy of sampling.

[0006] In summary, the shortcomings of existing building geotechnical drilling and sampling devices in terms of support adaptability, component adjustability, dynamic positioning accuracy, and locking reliability can no longer meet the needs of modern building geotechnical engineering investigation for efficient, accurate, and flexible sampling. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable drilling and sampling device for building geotechnical applications.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable drilling and sampling device for building soil and rock, comprising: a main frame for overall support and structural bearing; a support assembly including a support base plate rotatably disposed on both sides of the main frame for stable support of the device on the ground; a sampling assembly including a drilling bit disposed below the main frame for direct contact with soil and rock to achieve drilling and sampling; a moving assembly including a power transmission frame disposed above the drilling bit for driving the sampling device to move; and a locking assembly including a positioning pin slidably disposed on the main frame and the support base plate for locking the positions of the support base plate and the main frame.

[0009] As a further description of the above technical solution:

[0010] The support assembly also includes: an adjustable support column, threadedly connected to the support base plate, for adjusting the height of the support base plate; a support column base, fixedly connected below the adjustable support column, for increasing the contact stability between the adjustable support column and the ground; a rotating shaft, fixed to the bottom of the support base plate and rotatably mounted on the main frame of the device, for fixing the support base plate; and a fixing bolt, threadedly connected to the rotating shaft and also threadedly connected to the main frame of the device, for locking the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The sampling assembly also includes: a sampling tube, threadedly connected to the top of the drill bit, for containing the collected soil and rock samples; a tube body connector, threadedly connected to the top of the sampling tube, for connecting the sampling tube; and a drive motor, the output end of which is connected to the tube body connector via a coupling and bolted to the power transmission frame, for driving the tube body connector, the sampling tube, and the drill bit to rotate.

[0013] As a further description of the above technical solution:

[0014] Multiple sets of sampling tubes are prepared for connecting end to end to achieve lengthening.

[0015] As a further description of the above technical solution:

[0016] The moving component also includes: a power connection seat, which is bolted to the power transmission frame for moving the power transmission frame; a cylinder, which is mounted on the main frame of the device and whose output end is connected to the power connection seat for moving the power connection seat; and a guide groove, which is formed on the main frame of the device, with the two ends of the power transmission frame slidably connected in the guide groove for providing guidance for the power transmission frame.

[0017] As a further description of the above technical solution:

[0018] The two ends of the power transmission frame are T-shaped; the guide groove is T-shaped and fits the ends of the power transmission frame.

[0019] As a further description of the above technical solution:

[0020] The locking assembly also includes: a fixing plate, fixed to the main frame of the device, for limiting the range of movement of the positioning pin; and a spring, one end fixed to the fixing plate and the other end fixed to the positioning pin, for driving the positioning pin to reset.

[0021] This utility model has the following beneficial effects:

[0022] 1. Adapts to complex soil and rock sampling scenarios through multi-dimensional adjustment and stable support. The adjustable support column of the support component can be finely adjusted in height, and the support base plate can be adapted to uneven ground by rotating through the shaft. With the help of positioning pins and springs, the support angle can be quickly locked to ensure the stability of the device under different terrains. The cylinder-driven power transmission frame of the moving component moves smoothly along the T-shaped guide groove, driving the drilling bit to drill accurately and meet the needs of soil and rock sampling at different depths.

[0023] 2. Improved sampling efficiency through modular sampling structure and convenient operation.

[0033] Example 1:

[0034] like Figures 1 to 4As shown in the figure, this embodiment provides an adjustable drilling and sampling device for building geotechnical applications, comprising: a main frame 1 for overall support and structural bearing; a support assembly including a support base plate 21 rotatably mounted on both sides of the main frame 1 for stable support of the device on the ground; a sampling assembly including a drilling bit 31 mounted below the main frame 1 for direct contact with the geotechnical soil to achieve drilling and sampling; a moving assembly including a power transmission frame 41 mounted above the drilling bit 31 for driving the sampling device to move; and a locking assembly including a positioning pin 51 slidably mounted on the main frame 1 and the support base plate 21 for locking the positions of the support base plate 21 and the main frame 1.

[0035] In this embodiment, the support component, sampling component, moving component, and locking component constitute an adjustable drilling and sampling device for building geotechnical applications according to this application.

[0036] Understandable Figure 1 The diagram only schematically illustrates some of the components of the drilling sampling apparatus; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, drilling sampling equipment can also include components that are more advanced than... Figure 1 More or fewer parts.

[0037] It should also be understood that the drive motor 34 and cylinder 43 were purchased from the market and are common knowledge in the field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] In addition, in this embodiment, the main frame 1 of the device provides overall support; the support base plate 21 ensures the stability of the device on the ground; the drilling bit 31 rotates to contact the soil and rock for drilling and sampling; the power transmission frame 41 drives the sampling components to move and adjust the drilling depth; the positioning pin 51 locks the relative position of the support base plate 21 and the main frame 1 of the device; it can adapt to the sampling needs of soil and rock with different diameters, and the tilt of the device is reduced after support, and there is no obvious shaking during the sampling process, which meets the drilling and sampling requirements of building soil and rock foundations.

[0039] Specifically, the support components also include: an adjustable support column 22, threadedly connected to the support base plate 21, used to adjust the height of the support base plate 21; a support column base 23, fixedly connected below the adjustable support column 22, used to increase the contact stability between the adjustable support column 22 and the ground; a rotating shaft 24, fixed to the bottom of the support base plate 21 and rotatably mounted on the main frame 1 of the device, used to fix the support base plate 21; and a fixing bolt 25, threadedly connected to the rotating shaft 24 and threadedly connected to the main frame 1 of the device, used to lock the rotating shaft 24.

[0040] In this embodiment, the rotatable adjustable support column 22 adjusts the height of the support base plate 21 to adapt to uneven ground; the support column base 23 increases the contact area with the ground to improve stability; the rotating shaft 24 allows the support base plate 21 to rotate for storage or unfolding; tightening the fastening bolt 25 locks the rotating shaft 24 and fixes the angle of the support base plate 21; the height range of the adjustable support column 22 is adjustable, the support column base 23 is in stable contact with the ground, and the rotating shaft 24 does not rotate after the fixing bolt 25 is locked, thus enhancing the anti-tipping force of the support assembly.

[0041] Example 2:

[0042] Based on Example 1, in order to further improve sampling efficiency, a sampling component is arranged below the main frame 1 of the device;

[0043] Specifically, the sampling assembly also includes: a sampling tube 32, threadedly connected above the drilling bit 31, for accommodating collected soil and rock samples; a tube body connection 33, threadedly connected above the sampling tube 32, for connecting the sampling tube 32; and a drive motor 34, the output end of which is connected to the tube body connection 33 via a coupling and bolted onto the power transmission frame 41, for driving the tube body connection 33, the sampling tube 32, and the drilling bit 31 to rotate.

[0044] In a preferred embodiment, the drive motor 34 starts and drives the pipe body connection part 33, the sampling tube 32, and the drilling bit 31 to rotate synchronously through the coupling; the drilling bit 31 cuts the rock and soil, and the rock and soil sample enters the sampling tube 32 for storage, thus realizing drilling and sampling; the drilling rate can be adjusted according to the hardness of the rock and soil, and there is no jamming phenomenon during the sampling process.

[0045] Specifically, multiple sets of the sampling tube 32 are prepared for connecting end to end to achieve lengthening.

[0046] In this embodiment, according to the drilling sampling depth requirements, multiple sets of sampling tubes 32 are connected sequentially by end threads to increase the overall sampling tube length and adapt to deeper soil and rock sampling; after the sampling tubes 32 are connected, the coaxiality error is small and there is no sample leakage, which can adapt to the soil and rock sampling requirements at different depths.

[0047] Example 3:

[0048] Based on Example 2, in order to further improve sampling efficiency, a moving component is arranged below the main frame 1 of the device;

[0049] Specifically, the moving component also includes: a power connection seat 42, which is bolted to the power transmission frame 41 for moving the power transmission frame 41; a cylinder 43, which is mounted on the main frame 1 of the device and whose output end is connected to the power connection seat 42 for moving the power connection seat 42; and a guide groove 44, which is formed on the main frame 1 of the device, and the two ends of the power transmission frame 41 are slidably connected in the guide groove 44 for providing guidance for the power transmission frame 41.

[0050] With this configuration, the cylinder 43 is ventilated, and the piston rod extends and retracts, causing the power connection seat 42 and the power transmission frame 41 to move up and down along the guide groove 44. The power transmission frame 41 drives the sampling component drive motor 34, sampling tube 32, and drilling bit 31 to move up and down synchronously, adjusting the drilling depth. It moves downward to achieve drilling and moves upward to complete sampling before lifting. The power transmission frame 41 moves without jamming or deviating.

[0051] Specifically, the two ends of the power transmission frame 41 are T-shaped; the guide groove 44 is T-shaped and fits the ends of the power transmission frame 41.

[0052] The T-shaped end is embedded in the T-shaped guide groove 44. When the power transmission frame 41 moves up and down, the T-shaped structure restricts its lateral displacement, ensuring that the power transmission frame 41 moves only in the vertical direction, avoiding the sampling component from shifting and affecting drilling accuracy. The lateral displacement of the power transmission frame 41 is small when it moves, and the T-shaped guide has excellent stability.

[0053] Specifically, the locking assembly also includes: a fixing plate 52, which is fixed to the main frame 1 of the device and is used to limit the movement range of the positioning pin 51; and a spring 53, which is fixed at one end to the fixing plate 52 and at the other end to the positioning pin 51 and is used to drive the positioning pin 51 to reset.

[0054] In this embodiment, pulling the positioning pin 51 causes the spring 53 to extend, disengaging the positioning pin 51 from the positioning hole of the support base plate 21, thus adjusting the angle of the support base plate 21. Releasing the positioning pin 51 resets the spring 53. The fixing plate 52 limits the movement range of the positioning pin 51, preventing it from disengaging from the main frame 1 of the device. After locking, the support base plate 21 remains secure, and locking and unlocking can be completed by a single person.

[0055] In actual use, firstly, the support base plate 21 is rotated to a suitable angle using the pivot 24 to adapt to different working terrains. Then, the adjustable support column 22 is rotated, and its threaded connection with the support base plate 21 is used to adjust the height of the support base plate 21, ensuring the overall device remains level and stable. The support column base 23 increases the contact area with the ground, further enhancing support stability. After adjustment, the fixing bolts 25, which are threaded onto the pivot 24 and the main frame 1 of the device, are tightened to lock the position of the pivot 24, ensuring that the support base plate 21 will not rotate during operation.

[0056] Cylinder 43 drives the power transmission frame 41 to move. The two ends of the power transmission frame 41 are slidably connected to the T-shaped guide grooves 44 of the main frame 1 of the device. The guide grooves 44 provide precise guidance for the movement of the power transmission frame 41, ensuring its smooth up and down movement. Driven by the drive motor 34, the drilling bit 31 rotates at high speed, while the cylinder 43 pushes the power transmission frame 41 downward, causing the drilling bit 31 to drill into the rock and soil. The rock and soil sample enters the sampling tube 32 through the drilling bit 31, realizing sample collection. If it is necessary to increase the sampling depth, the sampling tube 32 can be lengthened by connecting multiple sets of sampling tubes 32 with threaded ends (using the tube body connection part 33) to meet the sampling requirements of different depths.

[0057] After sampling is completed, cylinder 43 drives the power transmission frame 41 to move upward, lifting the sampling assembly to the ground. Then, the sampling tube 32 is disassembled, and the soil and rock sample is removed. The fixing bolts 25 are loosened, the support base plate 21 is retracted, and the positioning pin 51 in the locking assembly, under the action of spring 53, slides into the corresponding hole in the main frame 1 and the support base plate 21. The fixing plate 52, in conjunction with the positioning pin 51, limits its movement range, further locking the relative position of the support base plate 21 and the main frame 1. Throughout the process, all components work together, and through the adjustment, locking, and power transmission of the mechanical structure, soil and rock drilling and sampling at different terrains and depths are achieved, with convenient operation and structural stability.

[0058] Both the drive motor 34 and the cylinder 43 are electrically connected to the PLC controller, which is electrically connected to an external power supply. The PLC controller facilitates the power supply control of the electrical equipment, ensuring that the equipment can be powered on when needed, thus avoiding the situation where power cannot be supplied when power is required.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
