Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to an automatic lifting experimental device and method for simulating rock-water interaction. Background Technology

[0002] During the service life of hydraulic engineering projects, the rock mass in the drawdown zone of the bank slope is exposed to a water-rock interaction environment for extended periods, which easily induces mechanical property degradation and cumulative damage effects, directly threatening the operational safety of the project. Among these factors, the number of wet-dry cycles, soaking duration, and rock moisture content are key influencing factors regulating this degradation and damage process. Therefore, by designing simulated water-rock interaction experiments under different wet-dry cycle gradients and soaking durations, and simultaneously monitoring the dynamic evolution of rock moisture content, the erosion mechanisms and intensity of each key factor on the bank slope rock and soil can be quantitatively revealed. This research not only provides a scientific basis for evaluating bank slope stability under water-rock interaction but also overcomes the limitations of existing water-rock interaction simulation experimental devices, further optimizing related experimental techniques and methods, and has significant engineering practice and academic reference value. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic lifting test device and method for simulating rock-water interaction, which realizes the simulation test of rock wet-dry cycle. Through motor power control and tensile sensor feedback, it is convenient to control the number of cycles, soaking time, drying time and rock moisture content in the simulation test of rock-water interaction.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic lifting test device for simulating rock-water interaction, including a rock sample placement platform, the rock sample placement platform including a base plate, a rock sample box provided on the base plate, inlet and outlet holes provided on the side wall of the rock sample box, an outer frame provided at the four corners of the base plate, a top plate fixedly provided at the upper end of the outer frame, a tension sensor provided at the top of the top plate, a top hook ring provided on the tension sensor, the top hook ring being connected to the lifting device, and a drying lamp provided at the bottom of the top plate; The lifting device, mounted on the top frame, moves the rock sample placement platform up and down within the soaking and drying zones. The soaking zone, drying zone, and top frame are stacked sequentially from bottom to top. The main body of the device comprises 16 rock sample placement platforms and 16 lifting devices, enabling simultaneous simulation of multiple rock-water interaction tests under different conditions. The rock sample placement platform can move freely up and down between the soaking zone, drying zone, and top frame via the lifting device, simulating wet-dry cycle or soaking of the rock sample within the sample box.

[0005] Preferably, the lifting device includes a motor, the output shaft of which is connected to a cable winch, a cable is wound on the cable winch, and a hook is connected to the end of the cable, which cooperates with a top hook ring.

[0006] Preferably, the motor is mounted on a fixed bracket, which is mounted on the top frame. The fixed bracket of the lifting device secures the motor to the crane beam of the top frame. The cable winch is vertical and horizontal, positioned at the vertical center line of the rock sample placement platform, ensuring that the cable overlaps with the vertical center line of the rock sample placement platform, thus ensuring smooth lifting of the rock sample placement platform.

[0007] Preferably, the soaking area includes a box body with an opening at the top and water inlets and outlets on the left and right sides, respectively. The soaking area is located at the bottom of the device, and the box body is an open square box with water inlets and outlets on the left and right sides to adjust the water level within the area. The opening at the top of the box body is slightly larger than the size of the grid bottom plate of the drying area but smaller than the size of the outer shell partition of the drying area, which facilitates the splicing of the drying area.

[0008] Preferably, the drying area includes an outer shell partition, with a grid top plate and a grid bottom plate at the top and bottom of the outer shell partition, respectively. The grid is used for the rock sample placement platform to pass through. The drying area is generally box-shaped, with 16 rounded rectangular holes in both the grid bottom plate and the grid top plate for the rock sample placement platform to move up and down. The size of the holes is similar to that of the bottom and top plates of the rock sample placement platform. The distance between the grid bottom plate and the grid top plate is similar to the height of the outer frame support column. The grid top plate protrudes and can be spliced ​​with the nested frame of the top frame.

[0009] Preferably, the top frame includes a nested frame, with support columns at the four corners of the nested frame, a square top frame at the top of the support columns, and a crane beam for placing the lifting device inside the square top frame.

[0010] Preferably, a bottom foot brace is provided between the support column and the nested frame, and a top diagonal brace is provided between the support column and the square top frame.

[0011] Preferably, the corners of the rock sample box are rounded.

[0012] A test method for an automatic lifting experimental device simulating rock-water interaction includes the following steps: S1. Select the number of rock sample placement platforms as needed, take out the rock sample boxes, place each rock sample in the center of each rock sample box, put the rock sample boxes back on the rock sample placement platforms, and install the top tension sensor. S2. Close the water outlet of the soaking area, connect the water inlet to the water source, open the water inlet and close the water inlet when the water level in the soaking area is appropriate.

[0013] S3. After connecting the drying area to the soaking area and ensuring its stability, install the top frame. Install a lifting device on the crane beam that is the same size as the required rock sample placement platform. Start the motor to retract the cable to the highest point and connect the top hook of the rock sample placement platform containing the rock sample to the hook of the lifting device.

[0014] S4. Start the motor and slowly lower the rock sample placement platform until the top plate of the rock sample placement platform is flush with the bottom plate of the drying zone grid. At this time, the rock sample is immersed in the test. After the immersion conditions required for the test are met, start the motor and slowly pull the rock sample placement platform up until the top plate of the rock sample placement platform is flush with the top plate of the drying zone grid. The drying lamp is turned on to dry the rock sample until the drying conditions required for the test are met.

[0015] S5. The tensile sensor provides real-time feedback on the tensile changes, thereby calculating the changes in the water content of the rock sample. Combined with the motor power output, the number of wet-dry cycles, soaking time, and drying time of the rock sample are controlled. Once the requirements of this set of tests are met, the motor pulls the rock sample onto the platform to the highest point, and the test ends. Tests that are not yet completed continue.

[0016] S6. After the test, take out the rock sample box and observe the results of the water-rock interaction simulation test. After all the tests in the device are completed and the rock sample is taken out, disconnect the power supply, open the water outlet, disconnect the water source at the inlet, disassemble the device from top to bottom and put it back in place.

[0017] Preferably, when multiple sets of tests are conducted simultaneously, the formula for calculating the water content of each set of rock samples is as follows: w=m w / m d =Δm / m d =ΔT / G d ; Where w is the rock water content (%); m w The mass (g) of water contained in the rock; m d Δm represents the mass of the dried rock (g); Δm represents the change in mass before and after water absorption (g); ΔT represents the change in tensile force (N) fed back by the tensile sensor; G d The gravity (N) acting on the dry rock sample.

[0018] This invention provides an automatic lifting experimental device and method for simulating rock-water interaction, which has the following beneficial effects: 1. This invention provides an automatic lifting experimental device and method for simulating rock-water interaction, making laboratory rock-water interaction simulation experiments more convenient, and providing more precise control and more intuitive observation feedback for factors affecting the results of rock-water interaction, such as soaking time, drying time, and rock moisture content.

[0019] 2. This invention uses 16 sets of rock sample placement platforms and a control lifting device to input motor power to simultaneously conduct rock water-rock interaction simulation tests with different soaking and drying times. The simulation tests can be compared with each other, improving the test efficiency.

[0020] 3. In this invention, up to 16 groups of soaking tests can be carried out simultaneously in the soaking area, which consumes less water than the traditional method of soaking a single group individually.

[0021] 4. This invention can regulate the soaking time of rocks by controlling the input motor power, and can achieve precise control of the drying and natural air drying time of rocks by combining the switching time of the drying lamp. Moreover, each group of experiments has strong independence, which improves the device's ability to simulate the water-rock interaction conditions of rocks.

[0022] 5. This invention uses a tensile sensor to provide real-time feedback on tensile changes, thereby inferring changes in rock moisture content. Combined with a lifting device and a drying lamp, it can precisely control changes in the internal moisture content of rocks during wet-dry cycle tests, making it more controllable than traditional simulated rock water-rock interaction test devices.

Detailed Implementation

[0024] An automatic lifting test device for simulating rock-water interaction includes a rock sample placement platform 100. The rock sample placement platform 100 includes a base plate 110, a rock sample box 120 on the base plate 110, and inlet and outlet drainage holes 122 on the side wall of the rock sample box 120. An outer frame 130 is provided at the four corners of the base plate 110. A top plate 140 is fixedly provided at the upper end of the outer frame 130. A tension sensor 150 is provided at the top of the top plate 140. A top hook 151 is provided on the tension sensor 150 and connected to a lifting device 200. A drying lamp 141 is provided at the bottom of the top plate 140. The lifting device 200 is mounted on the top frame 500 and is used to move the rock sample placement platform 100 up and down within the soaking zone 300 and the drying zone 400. The soaking zone 300, the drying zone 400, and the top frame 500 are stacked sequentially from bottom to top. The main body of the device has 16 sets of rock sample placement platforms 100 and 16 sets of lifting devices 200, which can simultaneously simulate multiple sets of rock-water interaction tests under different working conditions. The rock sample placement platform 100 can be freely raised and lowered between the soaking zone 300, the drying zone 400, and the top frame 500 via the lifting device 200, realizing the simulation of wet-dry cycle or soaking simulation of rock samples in the rock sample box 120.

[0025] The overall core architecture of the device was constructed, forming a complete experimental system through the rock sample placement platform, lifting device, and the soaking zone, drying zone, and top frame stacked from bottom to top, providing basic support for wet and dry cycle tests. The rock sample placement platform integrates key components such as inlet and outlet holes, tensile sensors, and drying lamps, which not only ensure water flow during soaking and precise heating during drying, but also provide data support for moisture content monitoring through tensile sensors. The integrated design of multiple components reduces the need for additional equipment, while the reliable connection between the top hook and the lifting device ensures the stability of the rock sample placement platform during lifting, thus improving the overall convenience and safety of the test.

[0026] Preferably, the lifting device 200 includes a motor 210, the output shaft of the motor 210 is connected to a cable winch 230, a cable 240 is wound on the cable winch 230, and a hook 250 is connected to the end of the cable 240. The hook 250 cooperates with the top hook ring 151.

[0027] The transmission logic is clear and the operation is stable, which can accurately control the lifting speed and position of the rock sample placement platform, perfectly adapting to the switching requirements of soaking and drying conditions; the cooperation between the hook and the top hook ring is not only reliable, avoiding the risk of falling off during the test, but also has the advantage of convenient disassembly and assembly, which facilitates the installation, replacement and maintenance of the rock sample placement platform and effectively improves the efficiency of test operation.

[0028] Preferably, the motor 210 is mounted on the fixed bracket 220, which is mounted on the top frame 500. The lifting device 200 and the fixed bracket 220 fix the motor to the crane beam 530 of the top frame 500. The cable winch 230 is vertical and horizontal, positioned at the vertical centerline of the rock sample placement platform 100, so that the cable overlaps with the vertical centerline of the rock sample placement platform 100, ensuring that the rock sample placement platform 100 is lifted and lowered smoothly.

[0029] Preferably, the soaking area 300 includes a box body 310 with an opening at the top and water inlets 320 and outlets 330 on the left and right sides, respectively. The soaking area 300 is located at the bottom of the device. The box body 310 is an open square box with water inlets 320 and outlets 330 on the left and right sides to adjust the water level within the area. The top opening of the box body 310 is slightly larger than the size of the grid base plate 410 of the drying area 400, but smaller than the size of the outer shell partition 420 of the drying area, which facilitates the splicing of the drying area 400.

[0030] The soaking area adopts an open square box structure, with water inlets and outlets on the left and right sides, which can flexibly adjust the water level in the area to adapt to different rock sample sizes and soaking depth requirements. The water inlet and drainage operations are independent and convenient. The opening at the top of the box body makes it easy to observe the soaking status of the rock sample, and its size design can also be well adapted to the drying area, ensuring the smooth splicing of each area of ​​the device and laying the foundation for smooth switching of experimental conditions.

[0031] Preferably, the drying zone 400 includes an outer shell partition 420, with a grid top plate 430 and a grid bottom plate 410 respectively provided at the top and bottom of the outer shell partition 420. The grid is used for the rock sample placement platform to pass through. The drying zone 400 is generally box-shaped. Both the grid bottom plate 410 and the grid top plate 430 contain 16 rounded rectangular holes for the rock sample placement platform 100 to move up and down. The size of the holes is similar to that of the bottom plate 110 and top plate 140 of the rock sample placement platform 100. The distance between the grid bottom plate 410 and the grid top plate 430 is similar to the height of the support column of the outer frame 130. The grid top plate 430 protrudes upward and can be spliced ​​with the nested frame 540 of the top frame 500.

[0032] The drying zone, through the outer shell partition and the mesh top and bottom plates, forms a relatively enclosed drying space, which can improve the drying efficiency of the drying lamp. The mesh hole size is precisely matched with the rock sample placement platform, which not only ensures that the rock sample placement platform can be raised and lowered freely to switch areas, but also ensures that the heat is evenly distributed during the drying process, avoiding insufficient drying of local rock samples, ensuring the consistency of drying conditions, and providing a guarantee for the reliability of test data.

[0033] Preferably, the top frame 500 includes a nested frame 540, with support columns 510 at the four corners of the nested frame 540, a square top frame 520 at the upper end of the support columns 510, and a crane beam 530 for placing the lifting device 200 inside the square top frame 520.

[0034] The top frame, through a combination of nested frames, support columns, a square top frame, and a crane beam, forms a stable load-bearing system that can reliably support the weight of multiple lifting devices, providing structural support for multiple parallel tests. The crane beam provides precise positioning for the lifting devices, ensuring that each lifting device is vertically aligned with the corresponding rock sample placement platform, avoiding deviation or jamming during lifting, and significantly improving the stability and accuracy of the device operation.

[0035] Preferably, a bottom foot support 512 is provided between the support column 510 and the nested frame 540, and a top diagonal support 513 is provided between the support column 510 and the square top frame 520.

[0036] Preferably, the corner 122 of the rock sample box 120 is a rounded corner.

[0037] An automatic lifting experimental device and method for simulating rock-water interaction includes the following steps: S1. Select the number of rock sample placement platforms 100 as needed, take out the rock sample boxes 120, place each rock sample in the center of each rock sample box 120, and then put the rock sample boxes 120 back into the rock sample placement platform 100. Install the top tension sensor 150. S2. Close the outlet 330 of the soaking area 300, connect the inlet 320 to the water source, open the inlet 320 and close the inlet 320 when the water level in the soaking area 300 is appropriate. S3. After splicing the drying zone 400 onto the soaking zone 300 and ensuring its stability, install the top frame 500. Install a lifting device on the crane beam 530 that is equal in size to the required rock sample placement platform 100. Start the motor 210 to retract the cable to the highest point. Connect the top hook 151 of the rock sample placement platform 100 containing the rock sample to the hook 250 of the lifting device 200. At this time, the tension measured by the tension sensor 150 is the weight of the rock sample placement platform 100 and the rock sample as a whole. The natural water content M0 of the rock sample can be calculated. S4. Start motor 210 and slowly lower the rock sample placement platform 100 until the top plate 140 of the rock sample placement platform 100 is flush with the bottom plate of the drying zone 300 grid. At this time, the rock sample is immersed in the test. After the immersion conditions required for the test are met, start motor 210 and slowly pull the rock sample placement platform 100 up until the top plate 140 of the rock sample placement platform 100 is flush with the top plate 410 of the drying zone 300 grid. Start drying lamp 141 to dry the rock sample until the drying conditions required for the test are met. If it is necessary to determine the natural moisture content of the rock sample, the rock sample placement platform 100 does not need to be lowered to the soaking zone 300 and is directly dried in the drying zone 400. The dried mass Md of the rock sample is measured and calculated using the tension sensor 150, according to the natural moisture content calculation formula: W0=M w / M d =(M0-M d ) / M d =(T0-T d ) / T d Where W0 is the natural moisture content (%); M w M represents the mass (g) of water contained within the rock. d M0 represents the mass of the dried rock (g); T0 represents the mass of the natural water content of the rock sample (g); T0 represents the tensile force (N) required to lift the naturally water-bearing rock sample based on feedback from the tensile sensor 150. d The required tensile force (N) to lift the dry rock is based on feedback from the tensile sensor 150. S5. The tensile sensor 150 provides real-time feedback on the tensile changes, thereby calculating the changes in the water content of the rock sample. Combined with the power output of the motor 210, the number of wet-dry cycles, soaking time, and drying time of the rock sample are controlled. Once the requirements of this set of tests are met, the motor 210 pulls the rock sample placement platform 100 up to the highest point, and this set of tests ends. Tests that are not completed continue. S6. After the test, take out the rock sample box 120 and observe the results of the water-rock interaction simulation test. After all the tests in the device are completed and the rock sample is taken out, disconnect the power supply, open the water outlet 330, disconnect the water source at the water inlet 320, disassemble the device from top to bottom and put it back in place.

[0038] When multiple sets of tests are conducted simultaneously, the formula for calculating the water content of each set of rock samples is: w=m w / m d =Δm / m d =ΔT / G d Where w is the rock water content (%); m w The mass (g) of water contained in the rock; m d Δm is the mass of the dried rock (g); Δm is the change in mass before and after water absorption (g); ΔT is the change in tensile force (N) fed back by the tensile sensor (150); G d The gravity (N) acting on the dry rock sample.

[0039] This device allows for precise control of rock soaking time by controlling the input motor power, and precise control of drying and natural air drying time by combining the on / off time of the drying lamp. Each group of experiments is highly independent, simulating various water-rock interaction conditions. Real-time feedback of tensile force changes via a tension sensor allows for the inference of rock moisture content changes. Combined with the lifting device and drying lamp, it can precisely control the internal moisture content changes of the rock during wet-dry cycle experiments, offering greater controllability than traditional simulated rock water-rock interaction test devices. This invention provides a more convenient laboratory simulation of rock erosion, offering more precise control and intuitive feedback on factors influencing the results of rock-water interaction, such as soaking time, drying time, and rock moisture content. It employs a top-frame structure with a bottom-up stacked soaking and drying zone, coupled with a rock sample placement platform integrating inlet / drainage holes, a drying lamp, and a tensile sensor, along with a motor-driven lifting device. This enables automatic switching between wet and dry cycles for the rock sample. Sixteen parallel design groups improve experimental efficiency and reduce water consumption. Motor power control precisely regulates soaking and drying times, and the tensile sensor provides real-time feedback on tensile changes, combined with a proprietary calculation formula to estimate the rock sample moisture content. Furthermore, precise adaptation of components and structural reinforcement design ensure the stability, controllability, and multi-condition simulation capabilities of the experiment, significantly optimizing the convenience and data accuracy of rock-water interaction simulation experiments.
