Description

Technical Field

[0001] The present invention relates to the technical field of hole depth measurement, and more specifically, to a hole depth measurement device for rock and soil geological survey in mountainous areas. Background Art

[0002] The hole depth measuring device for geological exploration of mountainous rock and soil can mainly measure the hole depth during the geological exploration process. The device can measure the depth of the borehole in the rock and soil in the mountainous area and provide accurate data support for geological exploration. This is of great use for understanding the distribution, thickness and geological structure characteristics of the underground rock strata. Secondly, when carrying out engineering construction in mountainous areas, tunnels, bridges, and foundation treatment all require detailed exploration of the underground rock strata. The hole depth measuring device can help engineers understand the specific conditions of the underground rock strata.

[0003] In the existing public documents, the patent with patent announcement number CN218179828U discloses a hole depth measuring device for rock and soil geological survey. This technology is provided with a rotating tape measure shaft on the support frame, and the outer wall of the tape measure shaft is wound with a tape measure, and a placement cage is provided at one end of the tape measure, and the prompt light and the speaker are fixedly connected to the placement cage. The block is rotated to the side away from the gear, and the handle is rotated to drive the tape measure shaft to rotate at a uniform speed, and the placement cage is slowly lowered into the borehole. When any one of the three micro switches contacts the bottom of the borehole, the circuit is connected, the indicator light emits light, and the speaker emits a sound to remind the user, and the borehole depth is directly read through the tape measure. The overall structure is simple, practical, and easy for users to operate. However, this technology still has the following problems.

[0004] During the geological survey of rock and soil in mountainous areas, although a tape measure can be dropped into the hole and moved downward using a placement cage, the hole is deep and the tape measure is long. The tape measure at the hole mouth is shaken by external force, which also causes the placement cage to shake. The placement cage is affected by the shaking and then offset. Even if the placement cage is placed at the bottom of the inner wall of the hole, the placement cage and the tape measure at the hole mouth will still have a tilt offset problem, making it difficult to keep the tape measure at the hole mouth and the tape measure at the bottom of the inner wall of the hole stably on the same vertical line, which will cause continuous shaking and the problem of tilted measurement of the tape measure. As a result, the depth measurement accuracy of the hole is greatly reduced when measuring geological survey holes for rock and soil in mountainous areas. Therefore, a hole depth measuring device for geological survey of rock and soil in mountainous areas is needed. Summary of the invention

[0007] When this technical solution is in use, the reduction motor drives the bidirectional screw to rotate inside the support frame. The bidirectional screw drives the two sleeves to move away from each other under the action of the thread transmission force. The sleeve moves to the left, and the other sleeve moves to the right. The groove plate drives the pressure sensor to move to the left, and the arc pressure plate is squeezed on one side of the inner wall of the hole, while the other arc pressure plate is squeezed on the other side of the inner wall of the hole. The arc pressure plate also squeezes the pressure sensor. When the pressure values ​​sensed by the two pressure sensors are the same as the pressure values ​​set by the main wireless controller, the reduction motor is turned off by the main wireless controller.

[0008] Preferably, the hole bottom positioning fitting measurement mechanism includes a transmission motor fixedly arranged at the top end of the inner wall of the slot column; a linkage screw is fixedly installed at the output end of the transmission motor, a torque sensor is fixedly installed at the bottom end of the linkage screw, and the torque sensor is fixedly connected to the slot column, the outer wall of the linkage screw is threadedly connected to a sleeve slot block, and the sleeve slot block is slidably connected to the slot column; both sides of the sleeve slot block are fixedly connected to support shafts, the outer wall of each support shaft is rotatably connected to a sleeve rod, and the inner wall of the sleeve rod rotates away from the support shaft position A linkage shaft is connected, one end of the linkage shaft is fixedly installed with a concave sleeve block, and the inner wall of the concave sleeve block is slidably connected with a sliding rod; one side of the concave sleeve block is fixedly connected with a connecting plate, and one end of the connecting plate is fixedly installed with a fixed pressure plate, and one end of the sliding rod is fixedly installed with a slot disk, the slot disk is fixedly connected to the counterweight cone, and the concave sleeve block is slidably connected to the slot disk; a secondary wireless sensor is provided on one side of the slot column, and a lower battery is provided on the other side of the slot column, and the secondary wireless sensor and the lower battery are both fixedly connected to the counterweight cone.

[0011] When the technical solution is in use, the positioning distance sensor on the counterweight cone is in a stable state, the positioning distance sensor senses the distance to the bottom surface of the inner wall at the bottom of the hole, and the sensed distance value is a fixed value, not a variable value. The calibration distance sensor can also perform distance calibration sensing on the bottom surface of the inner wall at the bottom of the hole, and the value sensed by the calibration distance sensor does not change. At the same time, the values ​​sensed by the calibration distance sensor and the positioning distance sensor are the same, and the lateral distance sensor can perform distance sensing on one side of the inner wall at the bottom of the hole. When the distance value sensed by the lateral distance sensor does not change, it is ensured that the counterweight cone is in a stable state, and the depth of the hole is measured more accurately.

[0012] Technical effects and advantages of the present invention: 1. The present invention uses an orifice positioning fitting measuring mechanism, a reduction motor drives the bidirectional screw to rotate inside the support frame, the two sleeve blocks move away from each other under the action of the thread transmission force, the groove plate drives the pressure sensor to move left, the pressure sensor drives the arc pressure plate to move left, the arc pressure plate is squeezed on one side of the inner wall of the orifice, and the other arc pressure plate is squeezed on the other side of the inner wall of the orifice, the arc pressure plate also squeezes the pressure sensor, when the pressure values ​​sensed by the two pressure sensors are the same as the pressure values ​​set by the main wireless controller, the reduction motor is turned off by the main wireless controller, so that the measuring tape is prevented from shaking greatly at the orifice position, and the measuring tape at the orifice position and the measuring tape at the bottom of the hole can be stably maintained on the same vertical line, thereby avoiding shaking during depth measurement, avoiding the problem of tilted measurement of the measuring tape, and greatly improving the accuracy of depth measurement when measuring rock and soil geological exploration holes in mountainous areas.

[0013] 2. The present invention adopts a hole bottom positioning fitting measurement mechanism, the counterweight cone drives the positioning distance sensor to move downward, the transmission motor drives the linkage screw to rotate, and the linkage screw drives the sleeve slot block to move downward under the action of the thread transmission force, and the sleeve slot block simultaneously drives the two support shafts to move downward, and the two support shafts respectively drive the top ends of the two sleeve rods to move downward synchronously, and the concave sleeve block slides forward along the inner wall of the slot plate, and the fixed pressure plate can be squeezed at one side of the inner wall of the bottom of the hole, and the other fixed pressure plate is synchronously squeezed at the other side of the inner wall of the bottom of the hole, so that the counterweight cone is located in the middle position of the bottom of the hole, and the counterweight cone can be in a stable state at the bottom of the hole, ensuring that the measuring tape at the hole mouth position and the measuring tape at the bottom of the hole are stably maintained on the same vertical line, avoiding the problem of tilted measurement of the measuring tape, and can greatly improve the accuracy of depth measurement when measuring rock and soil geological exploration holes in mountainous areas.

[0014] 3. The present invention utilizes multiple anti-sway detection components, and the positioning distance sensor performs distance sensing on the bottom surface of the inner wall of the bottom of the hole. The sensed distance value is a fixed value. The calibration distance sensor can also perform distance calibration sensing on the bottom surface of the inner wall of the bottom of the hole. The value sensed by the calibration distance sensor has not changed. The values ​​sensed by the calibration distance sensor and the positioning distance sensor are the same. The lateral distance sensor can perform distance sensing on one side of the inner wall of the bottom of the hole. The distance value sensed by the lateral distance sensor has not changed. This ensures that the counterweight cone is in a stable state, and keeps the counterweight cone stable and motionless during measurement. The counterweight cone can keep the slot column motionless, and the slot column can keep the bottom end of the measuring tape motionless. Only when the counterweight cone is ensured not to shake can the hole depth be measured and read, thereby greatly improving the accuracy of depth measurement when measuring rock and soil geological exploration holes in mountainous areas.

[0015] According to the mutual influence of the above-mentioned multiple effects, the arc pressure plate is first squeezed on one side of the inner wall of the hole mouth, and the other arc pressure plate is squeezed on the other side of the inner wall of the hole mouth. The limit sleeve can limit the downward movement of the measuring tape to avoid large shaking of the measuring tape at the hole mouth position, and then the fixed pressure plate can be squeezed on one side of the inner wall of the bottom of the hole, and the other fixed pressure plate is synchronously squeezed on the other side of the inner wall of the bottom of the hole. The counterweight cone can be in a stable state at the bottom of the hole. Finally, the value sensed by the calibration distance sensor does not change, the values ​​sensed by the calibration distance sensor and the positioning distance sensor are the same, and the distance value sensed by the lateral distance sensor does not change. In summary, the measuring tape at the hole mouth position and the measuring tape at the bottom of the hole can be stably maintained on the same vertical line, thereby avoiding shaking during depth measurement and avoiding the problem of tilted measurement of the measuring tape. When measuring geological exploration holes in mountainous areas, the accuracy of depth measurement can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom end surface of the calibration distance sensor 41 and the bottom end surface of the positioning distance sensor 42 are in the same horizontal plane, and the cross-sectional shape of the collar 40 is circular.

[0036] The working method of the hole depth measuring device for rock and soil geological survey in mountainous areas of the present invention is as follows: First, when the present invention is installed and positioned, the bottom end of the frame 1 is placed at the edge of the mountain rock geological survey hole, so that the limit sleeve 4 is located in the mountain rock geological survey hole, and the limit sleeve 4 is located in the middle of the mountain rock geological survey hole. Then, the frame 1 supports the support block 2, the support block 2 supports the electric cylinder 3, the electric cylinder 3 pushes the limit sleeve 4 downward, the limit sleeve 4 drives the limit sleeve plate 19 downward, and the limit sleeve plate 19 moves the proximity sensor 20 downward. When the bottom end surface of the proximity sensor 20 and the bottom end surface of the frame 1 are in the same plane position, the positioning and installation operation of the frame 1 can be completed.

[0037] Secondly, when the present invention performs orifice positioning and fitting measurement, the main wireless controller 24 is powered by the upper battery 23, the main wireless controller 24 starts the reduction motor 11, the reduction motor 11 drives the bidirectional screw 9 to rotate inside the support frame 6, and the bidirectional screw 9 drives the two sleeve blocks 10 to move away from each other under the action of the thread transmission force, the sleeve block 10 moves to the left, and the other sleeve block 10 moves to the right, the sleeve block 10 drives the groove plate 12 to move to the left, the groove plate 12 drives the pressure sensor 13 to move to the left, and the pressure sensor 13 drives the arc pressure plate 14 to move to the left, the arc pressure plate 14 is squeezed on one side of the inner wall of the orifice, and the other arc pressure plate 14 is squeezed on the other side of the inner wall of the orifice.

[0038] After the arc pressure plate 14 is squeezed and stressed, it will drive the connecting strip 15 to move right, and the connecting strip 15 will drive the sliding sleeve 16 to move right, and the sliding sleeve 16 will slide right along the outer wall of the guide column 17, and the sliding sleeve 16 will slide right along the inner wall of the slot plate 12 at the same time, and the arc pressure plate 14 will also squeeze the pressure sensor 13. When the pressure values ​​sensed by the two pressure sensors 13 are the same as the pressure values ​​set by the main wireless controller 24, the main wireless controller 24 will turn off the reduction motor 11, so that the limit sleeve 4 can be fixed at the center of the inner wall of the orifice. At the same time, the limit sleeve 4 can limit the downward movement of the measuring tape 5 to avoid large shaking of the measuring tape 5 at the orifice position, so as to achieve the orifice positioning and fitting measurement.

[0039] Then, when the present invention performs hole bottom positioning and fitting measurement, the rotating motor 22 is supported by the sleeve frame 1, and the main wireless controller 24 starts the rotating motor 22. The rotating motor 22 drives the rotating shaft 25 to rotate, and the rotating shaft 25 rotates inside the sleeve frame 1. At the same time, the rotating shaft 25 drives the reel 21 to rotate, and the reel 21 drives the measuring tape 5 to rotate and move downward. Under the gravity of the counterweight cone 8, the slot column 7 moves downward, and the slot column 7 drives the measuring tape 5 to move downward. The measuring tape 5 slides down steadily along the inner wall of the limit sleeve 4, and at the same time, the counterweight cone 8 drives the positioning distance sensor 42 to move downward, and the positioning distance sensor 42 performs distance sensing on the bottom surface of the inner wall of the bottom of the hole. When the distance sensed by the positioning distance sensor 42 fluctuates up and down by five centimeters, since the distance value sensed by the positioning distance sensor 42 will still change, it is known that the counterweight cone 8 still has a slight shaking problem, and the auxiliary wireless sensor 38 is connected to the main wireless controller 24, and the main wireless controller 24 turns off the rotating motor 22 and stops the downward release of the measuring tape 5.

[0040] The secondary wireless sensor 38 is powered by the lower battery 39, and the secondary wireless sensor 38 can start the transmission motor 26. The transmission motor 26 drives the linkage screw 27 to rotate, and the linkage screw 27 drives the sleeve groove block 29 to move downward under the action of the thread transmission force. The sleeve groove block 29 slides down along the inner wall of the groove column 7, and the sleeve groove block 29 drives the two support shafts 30 to move downward at the same time. The two support shafts 30 respectively drive the top ends of the two sleeve rods 31 to move downward synchronously, and the sleeve rod 31 drives the linkage shaft 32 to move forward, and the linkage shaft 32 drives the concave sleeve block 33 to move forward, and the concave sleeve block 33 moves forward along the inner wall of the sliding rod 34.

[0041] At the same time, the concave sleeve block 33 slides forward along the inner wall of the groove plate 37, and the counterweight cone 8 supports the groove plate 37, and the fixed pressure plate 36 can be squeezed on one side of the inner wall of the bottom of the hole, and the other fixed pressure plate 36 is synchronously squeezed on the other side of the inner wall of the bottom of the hole, so that the counterweight cone 8 is located in the middle position of the bottom of the hole. At the same time, the counterweight cone 8 is limited on both sides by two fixed pressure plates 36, so that the counterweight cone 8 can be in a stable state at the bottom of the hole, avoiding the problem of shaking of the counterweight cone 8.

[0042] Finally, when the present invention performs multiple anti-sway detection readings and the counterweight cone 8 no longer shakes, the positioning distance sensor 42 on the counterweight cone 8 is in a stable state, and the positioning distance sensor 42 senses the distance to the bottom surface of the inner wall of the bottom of the hole. At the same time, the sensed distance value is a fixed value rather than a changing value. At the same time, the ring 40 supports the calibration distance sensor 41, and the calibration distance sensor 41 can also perform distance calibration sensing on the bottom surface of the inner wall of the bottom of the hole. The value sensed by the calibration distance sensor 41 has not changed, and the counterweight cone 8 is in a stable state.

[0043] At the same time, the values ​​sensed by the calibration distance sensor 41 and the positioning distance sensor 42 are the same, and the collar 40 supports the sleeve frame 43 at the same time, and the sleeve frame 43 supports the lateral distance sensor 44, and the lateral distance sensor 44 can sense the distance on one side of the inner wall at the bottom of the hole. When the distance value sensed by the lateral distance sensor 44 does not change, it is ensured that the counterweight cone 8 is in a stable state. In this way, the counterweight cone 8 can be kept stable and motionless during measurement, and the counterweight cone 8 can keep the slot column 7 motionless, and the slot column 7 can keep the bottom end of the measuring tape 5 motionless, and at the same time keep the measuring tape 5 at the position of the limit sleeve 4 motionless, so that the distance value indicated by the indicator needle 18 on the measuring tape 5, plus the distance value sensed by the positioning distance sensor 42, is the depth value of the hole. The value of the positioning distance sensor 42 is wirelessly transmitted to the main wireless controller 24 through the auxiliary wireless sensor 38, and the specific value is displayed by the main wireless controller 24, so that the measurement operation of the rock and soil geological exploration hole in the mountainous area is completed, and the shaking problem during measurement is avoided, so that the depth of the hole is measured more accurately.
