Description

Technical Field

[0001] This disclosure relates to the field of experimental equipment technology, specifically to an experimental device and method suitable for automatic slope compaction and slope cutting. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] Experimental studies on slopes can lead to a better understanding of the stability and behavior of soil slopes, helping to improve and validate theoretical models. Currently, slope models can be used to test the effectiveness of new slope stability measures, drainage systems, or support structures to guide design and decision-making in engineering practice. This series of slope experiments can simulate slope behavior under different conditions in a controlled environment, providing valuable data for soil mechanics and geogeology research, thereby improving the quality and safety of soil slope management and engineering design.

[0004] On the other hand, slope models face several challenges when used in scientific experiments. First, the unevenness of the fill can lead to uneven soil distribution, affecting the reliability of experimental results. Incorrect soil compaction, moisture content, or particle size distribution may cause slope behavior to deviate from reality. Second, the uncontrollable slope may prevent the simulation of real slope gradients and topographic features, making it difficult to correlate experimental results with practical applications.

[0005] The inventors discovered that current research on slope models mainly focuses on creating large-scale models. Regarding slope models, existing models mostly rely on manual filling during the backfilling process, which has drawbacks such as the inability to evenly compact the soil layers and the inability to flexibly adjust and control the slope angle. This results in uneven slope surfaces and is time-consuming, labor-intensive, and costly. Summary of the Invention

[0006] To address the aforementioned problems, this disclosure proposes a test device and method suitable for automatic slope compaction and slope cutting. By adjusting the structure, the accuracy of slope cutting and the flatness of the slope surface are improved, the speed of slope cutting and compaction is accelerated, and the effect of saving time and labor is achieved.

[0007] According to some embodiments, the present disclosure adopts the following technical solutions:

[0008] An experimental device for automatic slope compaction and slope cutting includes a slope model and an automatic compaction and slope cutting device. The automatic compaction and slope cutting device is suspended above the slope model. The automatic compaction and slope cutting device includes a support structure and a workbench. A hydraulic rod is fixed to one side of the workbench. One end of the hydraulic rod is fixedly connected to the workbench. The inverted T-shaped platform includes a cross-section and a fixing plate. The other end of the hydraulic rod is connected to the fixing plate. Two snap-fit ​​grooves are provided on the top of the fixing plate. The snap-fit ​​grooves are rotatably connected to one end of a connecting rod. The other end of the connecting rod is fixed to the workbench.

[0009] The support structure includes a crossbeam, and the workbench is slidably connected to the crossbeam via a multi-section telescopic mechanism. One end of the multi-section telescopic mechanism is slidably connected to the crossbeam, and the other end is connected to the workbench via a spherical mechanism.

[0010] Furthermore, the support structure also includes two secondary support rods, which are placed vertically on both sides of the slope model.

[0011] Furthermore, the crossbeam includes a cylindrical crossbeam and an extended crossbeam. The extended crossbeam is nested and slidably connected to one end of the cylindrical crossbeam. The upper end of each secondary support rod is rotatably connected to both ends of the crossbeam through a limiting and fixing slot. The crossbeam is placed horizontally above the slope model.

[0012] Furthermore, a telescopic sliding track is provided between the cylindrical beam and the extended beam, and the diameter of the cylindrical beam is smaller than the diameter of the extended beam.

[0013] Furthermore, the overlapping section of the cylindrical crossbeam and the extended crossbeam is provided with through holes at unit intervals, and is fixed by bolts. The working area of ​​the crossbeam slide rail has a minimum adjustment distance based on the spacing of each through hole.

[0014] Furthermore, each secondary support rod has a primary support rod at its lower end. The primary support rod has an electric push rod inside. The electric push rod includes a fixed part and a telescopic part. The telescopic part is a multi-section telescopic structure. One end of the telescopic part is connected to the lower end of the secondary support rod, and the fixed part is fixed to the bottom end of the primary support rod.

[0015] Furthermore, a triangular sliding member is provided below the primary support rod, and the primary support rod and the triangular sliding member are fixed together by a nut. A slide rail is provided below the triangular sliding member, and the triangular sliding member is slidably connected to the slide rail.

[0016] Furthermore, a motor is installed on the outside of the secondary support rod. The motor is electrically connected to the crossbeam to provide steering force, and the rotation is kept stable by the limiting and fixing slot.

[0017] Furthermore, the bottom of the inverted T-shaped platform is a smooth plane to serve as a compaction contact surface, while the front end is a regular triangular prism to facilitate slope cutting operations; a sliding groove is provided below the crossbeam, allowing the multi-section telescopic mechanism to slide left and right along the crossbeam.

[0018] According to some embodiments, the present disclosure adopts the following technical solutions:

[0019] A method for a test device suitable for automatic slope compaction and slope cutting, comprising:

[0020] Fix the test device suitable for automatic slope compaction and slope cutting. Determine the position of the through hole of the crossbeam and the expandable crossbeam according to the boundary size of the slope model, adjust their length, and at the same time determine the rising height of the motor push rod in the first-level support rod and adjust the working range.

[0021] The hydraulic rod retracts, and the inverted T-shaped platform begins to rotate. When the bottom surface of the inverted T-shaped platform is observed to be in a horizontal state, the hydraulic rod stops working, the motor located outside the secondary support rod starts working, the crossbeam and the extension crossbeam begin to rotate, the limit fixing slot makes the multi-section telescopic mechanism in a vertical state, and the motor stops working.

[0022] The multi-section telescopic mechanism extends its internal rods to lower the workbench to contact the top surface of the slope. When the pressure sensor reading reaches the standard, the multi-section telescopic mechanism retracts and resets, completing the compaction of the same area of ​​the bottom surface of the inverted T-shaped platform. The above process of moving the workbench and extending and resetting the multi-stage mechanism is repeated until the soil on the top surface of the slope model is compacted.

[0023] After compaction, the motor on the outside of the secondary support rod rotates, causing the value on the dial to reach the beveling angle. The hydraulic rod retracts, the connecting rod remains stationary, and the inverted T-shaped platform begins to adjust its angle. When the inverted T-shaped platform and the multi-stage telescopic mechanism are parallel again in space, all angle adjustments are complete.

[0024] Referring to the light emitted by the laser light installed on the inverted T-shaped platform, move the worktable so that the front edge of the inverted T-shaped platform is aligned with the position of the top of the slope. Control the extension of the multi-stage telescopic mechanism to start the slope cutting. After one slope cutting is completed, the multi-stage telescopic mechanism retracts and resets. Repeat the process of moving the worktable and extending and resetting the multi-stage mechanism until the top surface of the slope is cut.

[0025] Compared with the prior art, the beneficial effects of this disclosure are as follows:

[0026] This disclosure provides a test apparatus and method suitable for automatic slope compaction and slope cutting. The test apparatus is fixed in place. Based on the boundary size of the slope model, the positions of the through holes in the crossbeam and the expandable crossbeam are determined, and their lengths are adjusted. Simultaneously, the rising height of the motor push rod inside the primary support rod is determined, and the working range is adjusted. The multi-section telescopic mechanism extends its internal rods, causing the worktable to fall and contact the top surface of the slope. The motor on the outside of the secondary support rod rotates, causing the value on the dial to reach the slope cutting angle. The hydraulic rod retracts, while the connecting rod remains stationary. The inverted T-shaped platform begins to adjust its angle. When the inverted T-shaped platform and the multi-stage telescopic mechanism are parallel again in space, all angle adjustments are complete. This improves the accuracy and smoothness of slope cutting, accelerates the slope cutting and compaction speed, and achieves time and labor savings. It also ensures the consistency of soil compaction on the slope, facilitating a series of comparative experiments on the slope and correcting the test results. Attached Figure Description

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0038] Example 1

[0039] One embodiment of this disclosure provides a test device suitable for automatic slope compaction and slope cutting, including a slope model and an automatic compaction and slope cutting device, wherein the automatic compaction and slope cutting device is suspended above the slope model, as shown below. Figure 1 , Figure 2 As shown, the automatic compaction and slope cutting device includes a support structure and a workbench 7. A hydraulic rod 9 is fixed on one side of the workbench 7, and one end of the hydraulic rod 9 is fixedly connected to the workbench 7. The inverted T-shaped table includes a cutting surface 16 and a fixing plate. The other end of the hydraulic rod is connected to the fixing plate. Two snap-fit ​​grooves 10 are provided on the top of the fixing plate. The snap-fit ​​grooves 10 are rotatably connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is fixed on the workbench 7.

[0040] The supporting structure includes a crossbeam. The worktable is slidably connected to the crossbeam via a multi-section telescopic mechanism 15. One end of the multi-section telescopic mechanism 15 is slidably connected to the crossbeam, and the other end is connected to the worktable 7 via a spherical mechanism 11.

[0041] As one example, such as Figure 1 , Figure 3 As shown, the support structure also includes two secondary support rods 3, which are placed vertically on both sides of the slope model.

[0042] like Figure 1 , Figure 3 As shown, the crossbeam includes a cylindrical crossbeam 6 and an extended crossbeam 5. The extended crossbeam 5 is nested and slidably connected to one end of the cylindrical crossbeam 6. The upper end of each secondary support rod 3 is rotatably connected to both ends of the crossbeam through a limiting fixing slot 4. The crossbeam is placed horizontally above the slope model for adjustment during compaction and slope cutting.

[0043] Furthermore, both ends of the cylindrical beam 6 are slidably connected to extended beams. A telescopic sliding track is set between the cylindrical beam 6 and the extended beam 5. The diameter of the cylindrical beam 6 is smaller than the diameter of the extended beam 5, which allows the cylindrical beam to be pulled out from the extended beam through the telescopic sliding track to adjust the length of the beam to adapt to different slope models. The extended beam can be moved outward. Before the device is fixed, the sliding track inside the beam can be extended according to the actual situation to expand the horizontal working area of ​​the workbench.

[0044] The overlapping section of the cylindrical crossbeam 6 and the extended crossbeam 5 is provided with through holes at unit intervals, and is fixed by bolts. The working area of ​​the crossbeam slide rail is adjusted to the minimum distance between each through hole. After adjusting to a certain distance, it is fixed by bolts before proceeding to the next step.

[0045] In one embodiment, a primary support rod 2 is provided at the lower end of each secondary support rod 3. An electric push rod is provided inside the primary support rod 2. The electric push rod includes a fixed part and a telescopic part. The telescopic part is a multi-section telescopic structure. One end of the telescopic part is connected to the lower end of the secondary support rod 3. The fixed part is fixed to the bottom end of the primary support rod 2. The telescopic part moves up and down by controlling the forward and reverse rotation of the electric push rod, thereby adjusting the height of the secondary support rod. The telescopic part of the electric push rod is fixedly connected to the secondary support rod 3. A motor drive is also installed on the outside of the secondary support rod 3 to limit the minimum height of the secondary support rod 3.

[0046] A triangular sliding rod 14 is installed below the primary support rod 2. The primary support rod 2 and the triangular sliding rod 14 are fixed together by a nut. A slide rail 13 is installed below the triangular sliding rod 14, and the triangular sliding rod 14 is slidably connected to the slide rail 13. A motor is installed at the rear end of the bottom slide rail to drive the worktable to move back and forth, realizing the overall movement and adjustment of the device above the slide rail. The slide rail is fixed to the test site by a detachable nut 1.

[0047] A motor is installed on the outside of the secondary support rod 3. The motor is electrically connected to the crossbeam and provides steering force. The motor drives the entire crossbeam to rotate. The extended crossbeam and the cylindrical crossbeam rotate simultaneously along the axis without relative rotation. A limiting and fixing slot is used to stabilize the rotated crossbeam. A scale is installed at one end of the extended crossbeam 6. Initially, when the device is in the compaction working state, the scale should be 90 degrees. The value displayed on the scale is the slope angle when the crossbeam is rotated by the motor.

[0048] like Figure 4 As shown, a sliding slot is provided below the crossbeam, allowing the multi-section telescopic mechanism to slide left and right along the crossbeam. The sliding slot is a linear guide slider, powered by a stepper motor mounted on its side. The slider also includes a small support platform, which is fixedly connected to the multi-section telescopic mechanism. This platform is used to drive the multi-section telescopic mechanism to move left and right.

[0049] Furthermore, the multi-section telescopic mechanism is designed with telescopic joints, allowing for adjustment of its vertical length. Simultaneously, when the extending beam and the cylindrical beam rotate around their axis, they also drive the multi-section telescopic mechanism to rotate. The spherical mechanism connecting the multi-section telescopic mechanism to the worktable is also capable of rotation.

[0050] Furthermore, the multi-section telescopic mechanism is driven by a motor, which is fixed to a small support platform on the sliding block. To provide greater compaction force, motors are placed inside both multi-section telescopic mechanisms.

[0051] like Figure 2 As shown, the bottom of the inverted T-shaped platform is a smooth plane, which serves as a compaction contact surface. The front end is a regular triangular prism, which facilitates slope cutting operations. A hydraulic rod 9 is fixed on one side of the workbench 7, and one end of the hydraulic rod 9 is fixedly connected to the workbench 7. The inverted T-shaped platform includes a cut surface and a fixed plate. The other end of the hydraulic rod 9 is connected to the fixed plate. Two snap-fit ​​grooves 10 are provided on the top of the fixed plate. The snap-fit ​​grooves 10 are rotatably connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is fixed on the workbench 7.

[0052] Furthermore, the workbench is divided into two independent spaces: the upper space houses the device's control box, and the lower space is used for connecting hydraulic rods and linkages. The control box contains an integrated control system that connects to the outside via a wireless module, enabling remote control of device parameters. All electric mechanisms installed in the device are connected to the integrated control system via wireless / wired connections. In any operating state, the rear end of the inverted T-shaped platform should extend beyond the rear of the control box to prevent positional conflict with the outer support frame of the soil when the workbench descends for compaction.

[0053] The bottom plane of the inverted T-shaped platform is parallel to the two multi-section telescopic mechanisms in space. The hydraulic rods of the worktable retract or extend, causing the connecting rods and the bottom surface of the inverted T-shaped platform to move at an angle. In order to meet the compaction requirements during the compaction work, a plane pressure sensor and a laser light are installed on the bottom surface of the inverted T-shaped platform. The pressure sensor provides feedback to adjust the extension or retraction of the multi-section telescopic mechanisms, and the laser light is used to aim at specific positions.

[0054] Understandably, the inverted T-shaped platform is made of stainless steel, with its front bottom surface gradually tapering into a straight line to reduce resistance during slope cutting. Two laser lights, parallel to the cut surface, are also installed above its front side; when the device is cutting, the light emitted by these lights helps the front edge of the inverted T-shaped platform to accurately locate the top of the slope.

[0055] Example 2

[0056] One embodiment of this disclosure provides a method for a test device suitable for automatic slope compaction and slope cutting, comprising:

[0057] Fix the test device suitable for automatic slope compaction and slope cutting. Determine the position of the through hole of the crossbeam and the expandable crossbeam according to the boundary size of the slope model, adjust their length, and at the same time determine the rising height of the motor push rod in the first-level support rod and adjust the working range.

[0058] The hydraulic rod retracts, and the inverted T-shaped platform begins to rotate. When the bottom surface of the inverted T-shaped platform is observed to be in a horizontal state, the hydraulic rod stops working, the motor located outside the secondary support rod starts working, the crossbeam and the extension crossbeam begin to rotate, the limit fixing slot makes the multi-section telescopic mechanism in a vertical state, and the motor stops working.

[0059] The multi-section telescopic mechanism extends its internal rods to lower the workbench to contact the top surface of the slope. When the pressure sensor reading reaches the standard, the multi-section telescopic mechanism retracts and resets, completing the compaction of the same area of ​​the bottom surface of the inverted T-shaped platform. The above process of moving the workbench and extending and resetting the multi-stage mechanism is repeated until the soil on the top surface of the slope model is compacted.

[0060] After compaction, the motor on the outside of the secondary support rod rotates, causing the value on the dial to reach the beveling angle. The hydraulic rod retracts, the connecting rod remains stationary, and the inverted T-shaped platform begins to adjust its angle. When the inverted T-shaped platform and the multi-stage telescopic mechanism are parallel again in space, all angle adjustments are complete.

[0061] Referring to the light emitted by the laser light installed on the inverted T-shaped platform, move the worktable so that the front edge of the inverted T-shaped platform is aligned with the position of the top of the slope. Control the extension of the multi-stage telescopic mechanism to start the slope cutting. After one slope cutting is completed, the multi-stage telescopic mechanism retracts and resets. Repeat the process of moving the worktable and extending and resetting the multi-stage mechanism until the top surface of the slope is cut.

[0062] Specifically, the device suitable for automatic slope compaction and slope cutting is fixed with a detachable nut. The position of the through hole of the crossbeam and the expandable crossbeam is determined according to the boundary size of the slope model. At the same time, the rising height of the motor push rod in the first-level support rod is determined, and the working range of the slider is adjusted.

[0063] The hydraulic rod retracts, and the inverted T-shaped platform begins to rotate. When the bottom surface of the inverted T-shaped platform is observed to be horizontal, the hydraulic system stops operating. The motor located outside the secondary support rod then starts operating, causing the crossbeam and extension crossbeam to rotate. The limiting and fixing slots bring the multi-section telescopic mechanism into a vertical position, and the motor stops operating.

[0064] The slide rail at the bottom of the motor-driven device, in conjunction with the sliding slot on the crossbeam, moves the worktable to the upper corner of the slope model. The multi-section telescopic mechanism extends its internal rods to lower the worktable to contact the top surface of the slope for compaction. Once the pressure sensor reading reaches the standard, the multi-stage telescopic mechanism retracts and resets, completing the compaction of the same area on the bottom surface of the inverted T-shaped platform.

[0065] Repeat the above process of moving the workbench and extending and resetting the multi-stage mechanism until the soil on the top surface of the slope model is compacted.

[0066] After compaction is completed, the motor on the outside of the secondary support rod rotates, causing the value on the dial to reach the slope angle.

[0067] The hydraulic rods retract while the connecting rods remain stationary. The inverted T-shaped platform begins to adjust its angle. When the inverted T-shaped platform and the multi-stage telescopic mechanism are parallel again in space, all angle adjustments are complete.

[0068] Referring to the light emitted by the laser light mounted on the inverted T-shaped platform, move the worktable so that the front edge of the inverted T-shaped platform is aligned with the top line of the slope. Control the extension of the multi-stage telescopic mechanism to begin cutting the slope. After one cut is completed, the multi-stage telescopic mechanism retracts and resets, repeating the process of moving the worktable and extending and resetting the multi-stage mechanism, thus completing the cutting of the top surface of the slope.
