Description

Technical Field

[0001] This invention relates to the field of geostress measurement technology, specifically to an integrated multi-parameter geostress measurement device and method. Background Technology

[0002] Under natural conditions, the rock layers in the Earth's crust are affected by factors such as their own weight and structure, resulting in internal stress. When excavating tunnels, mines, etc., stress detection is required at various locations to ensure the overall stability of the excavation walls. The commonly used measurement method is the stress relief method.

[0003] For example, Chinese patent CN222481675U discloses a borehole stress gauge. When performing measurements, a central hole is drilled at a flat location on the tunnel or mine rock wall, and then the stress gauge's detection head is installed inside the hole.

[0004] Depending on the construction requirements, holes are typically drilled vertically to the rock surface within the tunnel to be measured. The hole depth can be set according to the requirements. The distance between the drill hole and the tunnel floor is generally about 1.5m, and the spacing between holes is about 1.2m.

[0005] However, when detecting stress in multiple directions, the levelness of the borehole and the orientation of the stress gauge probe must be ensured to guarantee the accuracy of the detection. However, the levelness of different areas in tunnels and roadways is not the same, making it difficult to automatically perform accurate stress detection.

[0006] Based on this, the present invention designs an integrated multi-parameter geostress measurement device and measurement method to solve the above problems. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0024] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7A multi-parameter geostress measurement integrated device includes a traveling trolley 1 and a drilling rig 4; it also includes a positioning adjustment mechanism 2, a bidirectional support propulsion structure 3 and an adjustable detection mechanism 5; The lower side of the traveling trolley 1 is symmetrically equipped with a fixing module 11 to stabilize the traveling trolley 1; a positioning adjustment mechanism 2 is installed on the traveling trolley 1. like Figure 6 and Figure 7 As shown, the positioning adjustment mechanism 2 includes a levelness adjustment component 21, a height adjustment component 22, and a leveling device 23. The levelness adjustment component 21 is mounted on the traveling trolley 1, the moving end of the levelness adjustment component 21 is equipped with the height adjustment component 22, and the levelness adjustment component 21 is equipped with a leveling device 23 for detecting levelness. The moving end of the height adjustment component 22 is equipped with a bidirectional support propulsion structure 3; the moving end of the bidirectional support propulsion structure 3 is equipped with a drilling rig 4 and an adjustable detection mechanism 5. like Figure 5 and Figure 6 As shown, the adjustable detection mechanism 5 includes a rotating structure 51, a stress gauge 52, and an angle self-checking structure 53; the rotating structure 51 is installed on the moving end of the bidirectional support propulsion structure 3, the stress gauge 52 is installed on the bidirectional support propulsion structure 3, and the detection part of the stress gauge 52 is connected to the rotating structure 51; the rotating structure 51 and the bidirectional support propulsion structure 3 are equipped with an angle self-checking structure 53 for detecting the relative angle of the detection part of the stress gauge 52.

[0025] The moving end of the bidirectional support propulsion structure 3 is equipped with a protective shell 12.

[0026] In this embodiment, when the multi-parameter geostress measurement integrated device is working, it moves in the roadway by a traveling trolley 1, and then the traveling trolley 1 is fixed by a fixing module 11 to ensure stability in the subsequent drilling and detection process. The levelness of the height adjustment component 22 is detected by the leveling device 23. Then, the levelness adjustment component 21 is operated to adjust the height adjustment component 22, so that the bidirectional support propulsion structure 3 at the moving end of the height adjustment component 22 is in a horizontal state, and the drilling rig 4, rotating structure 51 and stress gauge 52 on the bidirectional support propulsion structure 3 are level. Then, the height adjustment component 22 drives the bidirectional support propulsion structure 3 to move vertically, so that the bidirectional support propulsion structure 3 moves to a certain height, thereby making the detection points at the same height. The cooperation between the levelness adjustment component 21 and the height adjustment component 22 ensures the accuracy of subsequent detection. The drilling rig 4 is aligned with the detection point by the bidirectional support propulsion structure 3, and drilling is performed by the drilling rig 4. After drilling is completed, the drilling rig 4 is withdrawn, and then the rotating structure 51, stress gauge 52, and angle self-checking structure 53 on the bidirectional support propulsion structure 3 are aligned with the detection point. The rotating structure 51 drives the stress gauge 52 to rotate, so that the detection direction of the stress gauge 52 is oriented in the required direction. At the same time, the angle self-checking structure 53 detects the detection direction of the stress gauge 52. Thus, the accuracy of the detection is ensured while detecting stress in multiple directions. A set of bidirectional support propulsion structures 3 provides propulsion force to both the drilling rig 4 and the stress gauge 52, saving space. After the drilling rig 4 finishes drilling, the bidirectional support propulsion structure 3 aligns the stress gauge 52 with the detection position. Thus, the levelness of drilling and detection can be guaranteed with a single calibration, ensuring overall detection efficiency. After the test is completed, the stress gauge 52 is reset by the bidirectional support propulsion structure 3 and the rotation structure 51, and then the fixed module 11 is reset so that the traveling trolley 1 can continue to move to the next test position. Thus, when performing multi-parameter ground stress measurement, stress in different directions can be detected at different test points by the cooperation of the rotation structure 51, the angle self-checking structure 53 and the stress gauge 52.

[0027] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 5 As shown, the fixing module 11 includes a fixing cylinder 111, guide rods 112, a fixing moving frame 113, and ground spikes 114. The fixing cylinder 111 is fixedly installed on the lower side of the traveling trolley 1. The output end of the fixing cylinder 111 is fixedly connected to the fixing moving frame 113. Multiple guide rods 112 are fixedly installed on the fixing moving frame 113. The guide rods 112 are slidably connected to the traveling trolley 1. Multiple ground spikes 114 are evenly fixedly installed on the fixing moving frame 113.

[0028] like Figures 7-9 As shown, the leveling adjustment assembly 21 includes a leveling adjustment mounting bracket 211, a servo cylinder 212, and a universal connector 213. The leveling adjustment mounting bracket 211 is fixedly mounted on the traveling trolley 1, and multiple servo cylinders 212 are symmetrically distributed on the leveling adjustment mounting bracket 211. One end of a set of universal connectors 213 is fixedly connected to the leveling adjustment mounting bracket 211, and the other end of the universal connectors 213 is fixedly connected to the servo cylinder 212. One end of another set of universal connectors 213 is fixedly connected to the output end of the servo cylinder 212, and the other end of the universal connectors 213 is fixedly connected to the leveling mounting bracket 214. The height adjustment assembly 22 includes an adjustment module and a limiting support module. The adjustment module is symmetrically installed on the horizontal mounting frame 214, and the limiting support module is connected to the horizontal mounting frame 214 and the adjustment module. The adjustment module includes an adjustment servo motor 221, a threaded rod 222, a guide rail 223, a vertical adjustment moving frame 224, and a support inclined platform 225. The adjustment servo motor 221 is fixedly mounted on a horizontal mounting frame 214. The output end of the adjustment servo motor 221 is fixedly connected to one end of the threaded rod 222, and the other end of the threaded rod 222 is rotatably mounted on the horizontal mounting frame 214. The guide rail 223 is symmetrically fixedly mounted on both sides of the vertical adjustment moving frame 224. The guide rail 223 and the horizontal mounting frame 214 are slidably connected by a slider. The vertical adjustment moving frame 224 and the threaded rod 222 are threadedly connected by a threaded sleeve. Support inclined platforms 225 are evenly fixedly mounted on the vertical adjustment moving frame 224. The limiting support module includes a second guide rail 226, a support column 227, and a movable roller 228. The second guide rail 226 is symmetrically fixed on both sides of the horizontal mounting frame 214. Multiple support columns 227 are symmetrically installed on the bidirectional support and propulsion structure 3. Movable rollers 228 are rotatably installed on the lower side of the support column 227. The movable rollers 228 are rollingly connected to the support inclined platform 225. The leveling device 23 includes a mounting cylinder 231, a swing rod 232, a counterweight 233, and a pressure sensor 234. Two mounting cylinders 231 are symmetrically fixedly mounted on the lower side of the horizontal mounting frame 214. The swing rod 232 and the counterweight 233 are located inside the mounting cylinder 231. The upper end of the swing rod 232 is rotatably connected to the inner top of the mounting cylinder 231, and the lower end of the swing rod 232 is fixedly mounted with the counterweight 233. The pressure sensor 234 is symmetrically fixedly mounted on the mounting cylinder 231. The counterweight 233 is in contact with the pressure sensor 234. The rotation directions of the two sets of pendulum rods 232 are perpendicular to each other.

[0029] like Figure 5 As shown, the bidirectional support propulsion structure 3 includes a propulsion mounting platform 31, an indexing rotary table 32, a propulsion linear module 33, and a propulsion mounting plate 34. The propulsion mounting platform 31 is fixedly connected to the support column 227; the propulsion mounting platform 31 is slidably connected to the guide rail 226 through a slider limit; the indexing rotary table 32 is rotatably mounted on the propulsion mounting platform 31; the propulsion linear module 33 is fixedly mounted on the indexing rotary table 32, and the propulsion mounting plate 34 is fixedly mounted on the moving end of the propulsion linear module 33. The protective shell 12 is fixedly installed on the indexing rotary table 32; The indexing rotary table 32 is an electric indexing table, which is driven to rotate by a geared motor.

[0030] The drilling rig 4 is fixedly mounted on the propulsion mounting plate 34; like Figure 10As shown, the rotating structure 51 includes a rotary servo motor 511, a rotary mounting plate 512, and a detector mounting platform 513. The rotary servo motor 511 is fixedly mounted on the push mounting plate 34, and the output end of the rotary servo motor 511 is fixedly connected to the rotary mounting plate 512. The rotary mounting plate 512 is rotatably connected to the push mounting plate 34. The detector mounting platform 513 and the rotary mounting plate 512 are detachably connected by bolts and nuts. The stress gauge 52 is a borehole stress gauge, the detection probe 522 is used for detection, and the protective sleeve 523 is sleeved on the outside of the detection probe 522 and fixedly connected to the detection probe 522; one end of the detection probe 522 is fixedly installed on the detection instrument mounting platform 513; the external acquisition instrument 521 is used to collect and process the strain data detected by the detection probe 522; the external acquisition instrument 521 is fixedly installed on the push mounting plate 34, and the external acquisition instrument 521 is electrically connected to the detection probe 522. The angle self-testing structure 53 includes a reflective strip 531 and a laser rangefinder 532. The reflective strip 531 is fixedly installed on the outside of the detector mounting platform 513 and is spiral-shaped outside the detector mounting platform 513. The laser rangefinder 532 is fixedly installed on the push-mount plate 34.

[0031] In this embodiment, when the traveling trolley 1, positioning adjustment mechanism 2, bidirectional support propulsion structure 3, drilling rig 4, and adjustable detection mechanism 5 are working normally, the traveling trolley 1 moves in the roadway. When it moves to the detection position, the fixed cylinder 111 drives the fixed moving frame 113 to move. The fixed moving frame 113 moves vertically under the limiting action of multiple guide rods 112, thereby driving the ground spike 114 to move until the ground spike 114 is driven into the ground. The ground spike 114 fixes the traveling trolley 1, ensuring the stability of subsequent drilling and detection.

[0032] The horizontality of the mounting frame 214 is detected by the cooperation of two sets of swing arms 232, counterweights 233, and pressure sensors 234. If the mounting frame 214 is horizontal, the swing arms 232 and counterweights 233 are vertical under the action of gravity, and the values ​​of multiple pressure sensors 234 are the same. If the mounting frame 214 tilts, it causes the mounting cylinder 231 and pressure sensors 234 to tilt. Under the action of gravity, the swing arms 232 and counterweights 233 tend to move in the direction that keeps themselves vertical. At this time, the pressure sensor 234 on the tilted side supports the counterweight 233, and the counterweight 233 squeezes the pressure sensor 234 on the other side, so that the values ​​of multiple pressure sensors 234 are different. The height of multiple servo cylinders 212 is adjusted until the pressure values ​​detected by multiple pressure sensors 234 are the same. At this time, the mounting frame 214 is horizontal. Then, the servo motor 221 drives the threaded rod 222 to rotate, and the threaded rod 222 drives the vertical adjustment moving frame 224 to move. The vertical adjustment moving frame 224 moves horizontally under the limiting action of the guide rail 223 and the slider, thereby driving the support inclined platform 225 to move horizontally. The horizontal movement of the support inclined platform 225 drives the moving roller 228 to move. The support column 227 and the push mounting platform 31 can only move vertically under the limiting action of the guide rail 226 and the slider. Thus, the cooperation of the moving roller 228 and the support inclined platform 225 drives the support column 227 to move vertically, thereby adjusting the height of the push mounting platform 31, so that the detection point is at the same height or the height required by the design. The indexing rotary table 32 drives the linear propulsion module 33, the propulsion mounting plate 34, and the drilling rig 4 on the propulsion mounting plate 34 to rotate, aligning the drilling rig 4 with the detection point. The linear propulsion module 33 moves the drilling rig 4 via the propulsion mounting plate 34 to drill a hole. After drilling is completed, the linear propulsion module 33 retracts the drilling rig 4 via the propulsion mounting plate 34. After the indexing rotary table 32 rotates the linear propulsion module 33 and the propulsion mounting plate 34 by 90°, the linear propulsion module 33 moves the drilling rig 4, the rotary servo motor 511, the rotary mounting plate 512, the detector mounting platform 513, and the detection probe 522 via the propulsion mounting plate 34. Thus, when the indexing rotary table 32 rotates the linear propulsion module 33, the propulsion mounting plate 34, the rotary mounting plate 512, the detector mounting platform 513, and the detection probe 522, the roadway wall does not affect the rotation of the detection probe 522. After the indexing rotary table 32 rotates, the detection probe 522 is aligned with the detection point. A rotary servo motor 511 drives the rotary mounting plate 512 and the detector mounting platform 513 to rotate, thereby causing the protective cylinder 523 and the detection probe 522 on the detector mounting platform 513 to rotate, so that the sensing surface of the sensor on the detection probe 522 is aligned with the detection direction. During this process, the laser emitted by the laser range sensor 532 is reflected by the corresponding position of the reflective strip 531 and received by the laser range sensor 532. The reflective strip 531 is spirally arranged so that different positions of the reflective strip 531 are aligned with the laser range sensor 532 when the detector mounting platform 513 rotates. This results in different distances detected by the laser range sensor 532 between the detector mounting platform 513 and the reflective strip 531 when the detector mounting platform 513 rotates. Thus, the relative position of the detector mounting platform 513 is determined by the cooperation of the reflective strip 531 and the laser range sensor 532.

[0033] When the testing instrument mounting platform 513, the testing probe 522, and the protective cylinder 523 are rotated to the required testing angle, the linear propulsion module 33 drives the rotating mounting plate 512, the testing instrument mounting platform 513, the testing probe 522, and the protective cylinder 523 to be inserted into the borehole via the propulsion mounting plate 34; the stress is detected by the testing probe 522 and the external acquisition instrument 521.

[0034] Example 3: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, a measurement method for a multi-parameter integrated geostress measurement device includes the following steps: Step 1: When the traveling trolley 1 moves to the detection position, the fixed cylinder 111 drives the fixed moving frame 113 to move. The fixed moving frame 113 moves vertically under the limiting action of multiple guide rods 112, thereby moving the ground spike 114 until the ground spike 114 is driven into the bottom surface; the traveling trolley 1 is fixed by the ground spike 114. Step Two: By coordinating the two sets of swing arms 232, counterweights 233, and pressure sensors 234, the levelness of the horizontal mounting frame 214 is detected. If the horizontal mounting frame 214 is level, the swing arms 232 and counterweights 233 are vertical under gravity, and the values ​​of multiple pressure sensors 234 are the same. If the horizontal mounting frame 214 tilts, it causes the mounting cylinder 231 and pressure sensors 234 to tilt as well. Under gravity, the swing arms 232 and counterweights 233 tend to move in the direction that keeps them vertical. At this time, the pressure sensor 234 on the tilted side supports the counterweight 233, and the counterweight 233 presses against the pressure sensor 234 on the other side, causing the values ​​of multiple pressure sensors 234 to be different. Adjust the height of multiple servo cylinders 212 until multiple pressure sensors... The pressure values ​​detected by device 234 are the same; at this time, the horizontal mounting bracket 214 is horizontal; the servo motor 221 drives the threaded rod 222 to rotate, the threaded rod 222 drives the vertical adjustment moving bracket 224 to move, and the vertical adjustment moving bracket 224 moves horizontally under the limiting action of guide rail 223 and slider, thereby driving the support inclined platform 225 to move horizontally; the horizontal movement of the support inclined platform 225 drives the moving roller 228 to move; the support column 227 and the push mounting platform 31 can only move vertically under the limiting action of guide rail 226 and slider, thereby driving the support column 227 to move vertically through the cooperation of the moving roller 228 and the support inclined platform 225, thereby adjusting the height of the push mounting platform 31; so that the detection points are at the same height or the height required by the design; Step 3: The indexing rotary table 32 drives the linear propulsion module 33, the propulsion mounting plate 34, and the drilling rig 4 on the propulsion mounting plate 34 to rotate, aligning the drilling rig 4 with the detection point; the linear propulsion module 33 moves the drilling rig 4 via the propulsion mounting plate 34 to drill a hole; after drilling is completed, the linear propulsion module 33 retracts the drilling rig 4 via the propulsion mounting plate 34; after the indexing rotary table 32 drives the linear propulsion module 33 and the propulsion mounting plate 34 to rotate 90°, the linear propulsion module 33 drives the drilling rig 4, the rotary servo motor 511, the rotary mounting plate 512, the detector mounting platform 513, and the detection probe 522 to move via the propulsion mounting plate 34, so that when the indexing rotary table 32 drives the linear propulsion module 33, the propulsion mounting plate 34, the rotary mounting plate 512, the detector mounting platform 513, and the detection probe 522 to rotate, the roadway wall does not affect the rotation of the detection probe 522; after the indexing rotary table 32 rotates, the detection probe 522 is aligned with the detection point; Step 4: The rotary servo motor 511 drives the rotary mounting plate 512 and the detector mounting platform 513 to rotate, thereby driving the protective cylinder 523 and the detection probe 522 on the detector mounting platform 513 to rotate, so that the sensing surface of the sensor on the detection probe 522 is aligned with the detection direction; during this process, the laser emitted by the laser range sensor 532 is reflected by the reflective strip 531 at the corresponding position and then received by the laser range sensor 532. The reflective strip 531 is spirally arranged so that when the detector mounting platform 513 rotates, different positions of the reflective strip 531 are aligned with the laser range sensor 532; thus, the detector... When the mounting platform 513 rotates, the distance detected by the laser rangefinder 532 to the reflective strip 531 varies. Therefore, the relative position of the mounting platform 513 is determined through the cooperation of the reflective strip 531 and the laser rangefinder 532. When the mounting platform 513, the detection probe 522, and the protective cylinder 523 rotate to the required detection angle, the linear advance module 33, through the advance mounting plate 34, drives the rotating mounting plate 512, the mounting platform 513, the detection probe 522, and the protective cylinder 523 to be inserted into the borehole. The stress is detected by the detection probe 522 and the borehole acquisition instrument 521.
