Description

Technical Field

[0001] This invention relates to the field of red sandstone grading technology, specifically to a red sandstone grading device and its usage method that combines excavation parameters for deduction. Background Technology

[0002] Red sandstone, a common rock type, is widely used in civil engineering fields such as construction, roads, and bridges. Accurate assessment of its engineering properties is crucial for ensuring project safety and stability, and the classification of red sandstone grades is a key step in this assessment. Precise classification provides a reliable basis for engineering design and construction, such as rationally determining foundation bearing capacity, selecting appropriate foundation types, and assessing slope stability. This is of great significance for improving project quality, reducing project risks, and saving project costs.

[0003] The current red sandstone grading work usually involves excavating the red sandstone using industrial equipment such as trolleys, then manually judging the quality of the red sandstone or determining its quality through sampling and testing, and finally grading different types of red sandstone.

[0004] However, the existing red sandstone grading classification device and its usage method, which are derived from excavation parameters, have the following shortcomings:

[0005] Existing red sandstone grading devices cannot quickly distinguish the quality and grade of red sandstone based on current excavation parameters, resulting in low actual grading accuracy and long processing time. Furthermore, due to the inaccurate grading of red sandstone, it is impossible to establish an accurate data model and adjust the excavation strategy in a timely manner based on the data model, which increases the overall operating cost and makes it difficult to meet actual usage requirements.

[0006] Therefore, we propose a red sandstone grading device and its usage method that combines excavation parameters to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a red sandstone grading device and its usage method that combines excavation parameters. By setting up a drilling detection mechanism and combining excavation parameters, the device simulates the excavation and drilling work of red sandstone to obtain general information about the red sandstone sample.

[0061] according to Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a debris collection mechanism 10 is provided at the bottom of the workbench 1;

[0062] The debris collection mechanism 10 includes a fixed frame 1001, which is fixedly installed on the bottom of the workbench 1. A collection box 1002 is inserted inside the fixed frame 1001. A pull ring 1003 is installed at one end of the collection box 1002. A discharge port 1004 is opened through the top of the placement seat 4.

An observation window 18 is provided on the surface of the box door 17, and a handle 19 is fixedly installed on the surface of the box door 17.

[0066] according to Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, support legs 20 are installed at the four corners of the bottom of the workbench 1. Each support leg 20 is equipped with an anti-slip pad 21 on its top. The support legs 20 and anti-slip pads 21 provide stable support for the device, increase the friction with the ground, prevent the device from shaking or shifting, and improve the accuracy of the test and the safety of the device during use.

[0067] Working principle: First, the device is moved and transported to the designated location. The support legs 20 and anti-slip pads 21 provide stable support for the device to prevent it from shaking or shifting. Then, the external power supply equipment is connected to the electrical equipment inside the device to provide stable power and ensure the normal operation of the device.

[0068] In the immersion testing stage, firstly, the locking knob 15 is turned and pulled, causing the first hinge 13 to be stressed and the sealing door 14 to rotate and open. Then, the red sandstone sample to be graded is placed into the simulation test chamber 2. The servo motor 809 drives a single bidirectional lead screw 804 to rotate. At the same time, under the transmission action of the pulley 807 and the transmission belt 808, the two bidirectional lead screws 804 rotate synchronously, causing the two sets of clamping frames 805 to slide close together and clamp the red sandstone sample. Then, the second servo electric cylinder 801 pushes the mounting plate 802 down, causing the red sandstone sample to sink into the water in the water tank 5 for immersion testing.

[0069] In the simulation test phase, firstly, the red sandstone sample to be graded is placed on the placement seat 4. Then, the preset data of the trolley excavation is imported into the industrial control computer 901. Using the operation keyboard 904, a suitable detection model is formulated based on the excavation data. Next, the controller 902 controls the first servo electric cylinder 601 to push the sliding frame 603 to slide downward within the limit frame 602, causing the first connecting rod 605 to drive the pressure frame 606 to press the red sandstone sample firmly onto the placement seat 4. Then, the controller 902 controls the electric drill bit 705 to perform drilling tests on the red sandstone sample. During the test, the laser displacement sensor 707, pressure sensor 708, and vibration feedback sensor 709 collect displacement data, pressure data, and vibration data respectively, and transmit the collected information to the industrial control computer 901 for analysis and processing.

[0070] During the debris cleaning stage, the debris generated during drilling will first fall into the collection box 1002 through the discharge port 1004. After the drilling test is completed, pull the pull ring 1003 to pull the collection box 1002 out of the fixed frame 1001, so that the collected debris can be centrally processed.

[0071] In the grading stage, firstly, the industrial control computer 901 analyzes and processes the information obtained from the borehole test, and transmits the processed red sandstone sample information to the display 903 for display. Next, the staff records the information of the soaked red sandstone sample and inputs the information into the industrial control computer 901. The industrial control computer 901 merges and processes the information from the two tests on the red sandstone sample, compares it with the standard values, and grades the red sandstone sample. After grading, the excavation strategy for the red sandstone can be adjusted in a timely manner according to the different grades.

10. A method for using a red sandstone grading device derived from excavation parameters, characterized in that: The red sandstone grading device and its usage method based on excavation parameter derivation as described in claim 9 include the following steps: S1: Twist the locking knob (15) to open the sealing door (14), clamp and fix the red sandstone sample to be graded through the multi-size clamping mechanism (8), and then sink the red sandstone sample to be graded into the water tank (5) through the multi-size clamping mechanism (8) to conduct an immersion test on the red sandstone. S2: By pulling the handle (19), the box door (17) is opened, the red sandstone sample to be graded is placed on the placement seat (4), and the preset data of the trolley excavation is imported into the industrial control computer (901). The appropriate detection model is formulated using the operation keyboard (904), and the device is controlled by the controller (902) to work. S3: The controller (902) controls the first servo electric cylinder (601) to push the sliding frame (603) downward, causing the pressure frame (606) to press on the top of the red sandstone sample to be graded. At the same time, the controller controls the electric drill bit (705) to drill holes in the red sandstone sample. The laser displacement sensor (707), pressure sensor (708) and vibration feedback sensor (709) collect the data obtained from the drilling work. S4: The debris generated during drilling will fall into the collection box (1002) through the discharge port (1004). After the drilling work is completed, the collection box (1002) will be pulled out from the fixed frame (1001) by pulling the pull ring (1003) to centrally process the collected debris. S5: After drilling is completed, the clamping mechanism (6) releases the clamping state on the red sandstone sample. At the same time, the data collected by the laser displacement sensor (707), pressure sensor (708) and vibration feedback sensor (709) will be transmitted to the industrial control computer (901) for analysis and processing, and the general information of the red sandstone will be displayed on the display (903). S6: After soaking, by observing the sedimentation state in the water tank (5) and the remaining red sandstone sample, the information is completed and input into the industrial control computer (901). The industrial control computer (901) combines the general information obtained from the borehole detection and the sample information obtained from soaking to classify the measured red sandstone sample.
