Description

Technical Field

[0001] This invention relates to the field of mining drilling technology, and in particular to an automatic deviation correction device for directional drilling in mines. Background Technology

[0002] In the field of mining geological exploration and resource extraction, directional drilling technology is crucial for accurately obtaining underground information and implementing directional blasting or gas extraction. The accuracy of the drilling trajectory directly determines the project quality, operational safety, and overall drilling efficiency.

[0003] Currently, relying on rigid guide sleeves or simple hydraulic side thrust mechanisms for deviation correction has significant drawbacks. The former is a passive constraint and cannot actively correct existing deviations, leading to the accumulation of trajectory errors. Ultimately, more energy-intensive and time-consuming remedial corrections are necessary, directly impacting drilling footage efficiency. While the latter can actively apply force, its drive mechanism often has a long motion conversion chain and large transmission clearance, resulting in slow response to correction commands. This not only misses the optimal correction opportunity but also wastes a significant amount of energy in repeated ineffective actions, failing to meet energy-saving operation requirements. Furthermore, the lateral thrust generated by this mechanism suffers significant force loss and directional deviation when transmitted to the drill pipe through multiple stages of the structure. A large amount of energy intended to change the drill bit's direction is consumed by internal friction and deformation. Moreover, the support base itself is prone to elastic deformation when subjected to reaction forces. The variations or slight displacements create an inefficient working condition of pushing and pulling simultaneously, which wastes valuable drilling power and results in extremely poor energy-saving correction. During active correction, the clamping state cannot be adaptively adjusted, leading to a lack of coordination and even mutual interference between foundation stability, axial straightening stiffness, and lateral correction force. In harsh drilling environments, the drill pipe simultaneously bears drilling vibration, lateral forces from sudden formation changes, and active correction forces that cannot be effectively transmitted. This internal friction not only significantly reduces the correction effect and trajectory control accuracy but also easily causes structural fatigue and damage. Frequent tripping and tool changes severely slow down the drilling progress. This high-energy-consumption, low-precision, and low-reliability working condition ultimately greatly reduces the efficiency and accuracy of mining drilling and exploration results, representing a huge waste of resources and energy from a full-cycle perspective.

[0016] Each of the movable holes has a rotating cylinder movably installed inside. The outer circumference of the rotating cylinder has an S-shaped actuation groove, and an arc-shaped actuation rod is movably installed in the S-shaped actuation groove. The arc-shaped actuation rod is fixedly installed on the arc-shaped soil-dredging plate. A connecting groove is opened on the connecting plate, and the arc-shaped actuation rod moves through the connecting groove. A connecting rotating rod is connected between the rotating cylinders. A second bevel gear is fixedly installed at the end of the connecting rotating rod near the connecting cylinder, and the second bevel gear is movably meshed with the first bevel gear. Arc-shaped soil-dredging nails are fixedly installed at the bottom of each arc-shaped soil-dredging plate.

[0017] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0018] 1. In this invention, by guiding the continuous movement of the arc-shaped flipping shaft in the flipping groove and the pushing groove in the correction component, the efficient spatial motion conversion from rotation to precise lateral thrust is achieved. The correction response is rapid and accurate. The servo motor drives the first gear and the second gear to rotate the support rod. Then, through the first push rod and the second push rod, the arc-shaped flipping shaft is first flipped into the predetermined track, and then converted into the precise horizontal linear motion of the arc-shaped pushing block. This composite motion chain of rotation, flipping, and horizontal pushing achieves efficient conversion of motion form and precise directional output of force in a compact space. This makes the correction action both fast and controllable. The rapid and one-time correction capability means that the correction can be completed with minimal intervention in the early stage of deviation. This avoids the large deviation accumulated due to slow response and achieves high efficiency and energy saving in the drilling process.

[0019] 2. In this invention, the limiting roller and the first spring inside the arc-shaped clamping block of the surrounding clamping assembly form an elastic contact interface, providing dynamic and flexible follow-up alignment, effectively ensuring the initial verticality and drilling stability of the auger probe. During drilling, the limiting roller always maintains rolling contact with the guide cover and provides adaptive radial force under the action of the spring, realizing dynamic and flexible clamping of the probe. This not only restrains its lateral swing but also absorbs vibration and impact, avoiding damage that may be caused by rigid clamping, ensuring the smoothness of the drilling process, saving energy and time costs in the overall operation cycle, and improving the comprehensive energy efficiency of drilling operations.

[0020] 3. In this invention, workers manually rotate the rotating discs around the base plate to drive the fixed threaded rods into the soil, completing the initial leveling and fixing. Subsequently, the soil-digging locking component performs auxiliary anchoring. Its unique S-shaped actuating groove and arc-shaped actuating rod structure transforms the rotational motion of the rotating cylinder into a compound swing of the arc-shaped soil-digging plate downward and outward, driving the arc-shaped soil-digging nails to be inserted into the soil layer at the optimal angle. This auxiliary anchoring mode of manual coarse adjustment and mechanical fine locking ensures that the mobile base plate can be reliably locked under various complex ground conditions, providing a solid foundation for high-precision drilling, realizing rapid and accurate auxiliary anchoring, greatly improving the stability of the working foundation, and allowing the driving force of drilling and correction to be fully applied to effective rock breaking and trajectory control, avoiding ineffective energy dissipation between the equipment and the unstable foundation.

[0021] 4. In this invention, the lifting plate is driven by the screw at the bottom of the support rod in the correction and stabilization component, which forces the stabilizing cone to penetrate vertically and forcefully into the ground, establishing a rigid connection between the support plate and the ground. This transforms the entire support part into a stable force response fulcrum. When the correction component applies lateral thrust, it effectively prevents the support structure from collapsing or shifting, allowing the correction force to be transmitted to the auger probe without loss. This greatly improves the execution efficiency and reliability of the correction action, constructs a rigid force transmission fulcrum, and ensures that the correction force is fully and effectively applied to the auger probe.

[0022] 5. In this invention, when the stabilizing cone of the correction and stabilizing component is inserted to enhance the rigidity of the system, this increased rigidity, in turn, strengthens the clamping stability of the arc-shaped clamping block in the surrounding clamping component on the guide cover. This closed-loop synergy enables the device to promote each other in terms of basic stability, clamping rigidity, and correction efficiency during the correction process, realizing the self-optimization and enhancement of system performance under dynamic operating conditions. It creates a closed-loop synergistic mechanism of straightening, correction, and stabilization, which is ingeniously designed.

[0023] 6. In this invention, by replacing the sliding friction surface with a limiting roller in the surrounding clamping assembly and combining it with the first spring, elastic rolling contact with the guide cover is achieved, converting sliding friction into rolling friction. The spring also buffers the impact load, thereby significantly reducing the wear of the arc-shaped clamping block and the guide cover, reducing maintenance requirements, and improving the durability and reliability of the device in long-term harsh operating environments. The low-wear rolling contact and elastic buffer design significantly improves the service life of key components and the reliability of the equipment.

[0024] 7. In this invention, the power is synchronously distributed to multiple rotating cylinders through the rotating shaft, first bevel gear, second bevel gear and connecting rod in the soil-digging locking assembly, ensuring the synchronicity of the movement of all soil-digging plates, ensuring the uniformity and reliability of the anchoring force, realizing the synchronous centralized drive of multiple actuators by a single power source, simplifying the structure and improving control reliability, enabling the device to quickly establish a stable horizontal working platform on uneven and sloping working surfaces without relying on additional large-scale leveling projects, thereby enhancing the on-site adaptability and operational flexibility of the equipment.

[0035] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0036] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an automatic deviation correction device for directional drilling in mines includes a movable base plate 10, a side frame 11, and a hydraulic telescopic pump 12. A spiral drill probe 13 is installed at the bottom of the hydraulic telescopic pump 12. A support plate 20 is fixedly installed on the movable base plate 10. A guide and deviation correction component is installed on the support plate 20. The guide and deviation correction component is used to limit and guide the spiral drill probe 13 when it is drilling deeper. The guiding and correcting assembly includes a servo motor 31 and an arc-shaped push block 26. A fixed bracket 30 is fixedly installed on the support plate 20 at the end away from the movable base plate 10. Fixed threaded rods 18 are threaded around the movable base plate 10, and a rotating disk 19 is fixedly installed at the top of the fixed threaded rods 18. Universal rollers 14 are fixedly installed around the bottom of the movable base plate 10. The guiding and correcting assembly includes a first push rod 23 and a second push rod 24. A push groove 28 is formed at the end of the support plate 20 away from the movable base plate 10. An arc-shaped connecting block 27 is slidably connected in the push groove 28. The bottom of the arc-shaped connecting block 27 is movably connected to the arc-shaped push block 26 through a rotating shaft. A flip-up feature is formed at the end of the support plate 20 away from the movable base plate 10. The groove 29 is connected to the push groove 28. An arc-shaped flipping shaft 25 is movably connected through the flipping groove 29. The first push rod 23 and the second push rod 24 constitute the primary transmission. The sliding of the arc-shaped connecting block 27 in the push groove 28 and the through movement of the arc-shaped flipping shaft 25 in the flipping groove 29 are guided by the push groove 28 and the flipping groove 29. First, it is converted into the linear preparatory action of the arc-shaped connecting block 27, and then switched to the precise lateral displacement of the arc-shaped push block 26 through the arc-shaped flipping shaft 25. This composite kinematic chain of rotation, linear movement, flipping intervention and precise flat push realizes the flexible start and rigid termination of the correction action, which avoids sudden impact and ensures the precise controllability of the direction and magnitude of the final force.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A servo motor 31 is fixedly installed at the end of the support plate 20 away from the movable base plate 10. The output end of the servo motor 31 is fixedly installed with a first gear 32 via a rotating shaft. The support plate 20 is movably connected to a support rotating rod 21. A second gear 22 is fixedly installed at the bottom of the support rotating rod 21, and the second gear 22 is movably meshed with the first gear 32. The top of the support rotating rod 21 extends through to the outer side of the top of the fixed frame 30, and a first push rod 23 is fixedly installed at the top of the support rotating rod 21. A second push rod 24 is movably connected to the top of the arc-shaped flip shaft 25. The second push rod 24 is movably connected to the first push rod 23. An arc-shaped push block 26 is movably connected to the bottom of the arc-shaped flip shaft 25. The arc-shaped connecting block 27 and the arc-shaped flip shaft 25 both movably pass through the push groove 28.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 When the sensor detects a deviation in the drilling trajectory of the auger probe 13, the guide correction component will actively correct the deviation. The servo motor 31 will start and drive the support rod 21 to rotate through the first gear 32 and the second gear 22. The second push rod 24 at the top of the support rod 21 will rotate accordingly. The first push rod 23 and the second push rod 24 will cooperate. The first push rod 23 will drive the arc-shaped flip shaft 25 and the arc-shaped push block 26 at the bottom to produce lateral displacement, so that the arc-shaped flip shaft 25 enters the push groove 28 from the flip groove 29, and then flips the arc-shaped push block 26 and continues to move horizontally. The arc-shaped push block 26 cooperates with the arc-shaped flip shaft 25 to push along the push groove 28. The arc-shaped push block 26 will then drive the arc-shaped clamping block 40 to press against the side of the guide cover 17 of the auger probe 13, applying a precise lateral thrust, forcing the auger probe 13 to gradually return to the predetermined axis.

[0039] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The fixed frame 30 is equipped with a correction and stabilization component. While guiding the correction component to limit and correct the deviation of the auger drill probe 13, the correction and stabilization component provides reinforcement support for the support plate 20 relative to the ground, enhancing the stability of the auger drill probe 13 during operation. The correction and stabilization component also includes a lifting plate 34 that moves inside the fixed frame 30. The bottom of the support rod 21 extends through into the fixed frame 30, and a screw 33 is fixedly installed at the bottom end of the support rod 21. The screw 33 is threaded through and connected to the lifting plate 34. Stabilizing cones 35 are fixedly installed at both ends of the bottom of the lifting plate 34, and the stabilizing cones 35 move through the bottom of the fixed frame 30, thereby stabilizing and limiting the fixed frame 30 to the ground.

[0040] The fixed frame 30 has a fixed slide groove 36 inside, and a fixed slider 37 is slidably connected in the fixed slide groove 36. The lifting plate 34 is fixedly installed between the fixed sliders 37. The lifting plate 34 achieves stable and smooth lifting movement under the limit of the fixed slide groove 36 and the fixed sliders 37.

[0041] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8When the guiding correction component is working, in order to ensure the effective transmission of the correction thrust and prevent the support plate 20 from shifting, the correction stabilization component operates synchronously. When the servo motor 31 drives the support rotating rod 21 to rotate through the first gear 32 and the second gear 22, the screw 33 at its bottom drives the lifting plate 34 to move vertically downward along the fixed slide 36, pushing the stabilizing cone 35 at its bottom to forcefully insert into the ground. This action reinforces the fixed frame 30 and the support plate 20 connected to it with the ground into a whole, forming a rigid force response fulcrum, so that the correction force applied by the guiding correction component is fully applied to the auger drill probe 13, greatly enhancing the effectiveness of the correction action and the dynamic stability of the auger drill probe 13. The stabilizing cone 35 is vertically inserted into the ground, firmly fixing the support plate 20. This operation significantly enhances the rigidity of the entire device. The increase in device rigidity makes the horizontal clamping effect of the arc-shaped clamping block 40 on the guide cover 17 more stable and reliable.

[0042] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 A drilling hole is provided at the center of the movable base plate 10. A surrounding clamping assembly is provided inside the drilling hole to clamp and lower the auger drill probe 13. The surrounding clamping assembly includes an arc-shaped clamping block 40 that moves inside the drilling hole and a limiting roller 43. A U-shaped clamping rod 44 is movably connected to the bottom of the movable base plate 10 near the support plate 20. The arc-shaped clamping block 40 is fixedly installed on the U-shaped clamping rod 44. Several limiting holes 41 are evenly provided on the side of the arc-shaped clamping block 40 away from the support plate 20. A first spring 42 is fixedly installed at the bottom of each limiting hole 41, and the limiting roller 43 is fixedly installed at the top of the first spring 42. The limiting roller 43 moves within the limiting hole 41. A side frame 11 is fixedly installed on the top of the movable base plate 10. A hydraulic telescopic pump 12 is fixedly installed at the center of the top of the side frame 11. A motor cover 15 is fixedly installed on the bottom of the hydraulic telescopic pump 12. A rotary motor 16 is fixedly installed inside the motor cover 15. The auger drill probe 13 is fixedly installed on the output end of the rotary motor 16. A guide cover 17 is fixedly installed on the outer periphery of the top of the auger drill probe 13. The limiting roller 43 and the guide cover 17 move against each other. The limiting roller 43 supported by the first spring 42 contacts the guide cover 17, providing a continuous and buffered radial force. This can effectively constrain the lateral swing of the probe and prevent it from deviating significantly. It can also absorb the vibration and impact during drilling and avoid structural overload or probe surface damage that may be caused by pure rigid clamping.

[0043] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 The U-shaped clamping rod 44 has a second spring 45 fixedly installed at the end away from the arc-shaped clamping block 40, and the second spring 45 is fixedly connected to the movable base plate 10. The U-shaped clamping rod 44 moves inside the second spring 45. When the guide correction component pushes the arc-shaped clamping block 40 to actively correct the deviation, the limiting roller 43 can be elastically compressed or returned in its hole, so that the force between the arc-shaped clamping block 40 and the guide cover 17 is always in contact and the correction thrust is smoothly transmitted. The elastic element is integrated into a continuous and smooth guiding process, which significantly improves the responsiveness and control accuracy of the correction action.

[0044] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 When the arc-shaped push block 26 pushes the arc-shaped clamping block 40, the surrounding clamping assembly plays a role in straightening and buffering the auger drill probe 13. Specifically, the hydraulic telescopic pump 12 drives the rotary motor 16 and the auger drill probe 13 to descend for drilling. When the guide cover 17 on the outer periphery of the auger drill probe 13 passes through the drilling hole, it continuously contacts the limiting roller 43 set in the arc-shaped clamping block 40. Under the action of the limiting hole 41 and the first spring 42 in the arc-shaped clamping block 40, the limiting roller 43 achieves flexible clamping and limiting of the auger drill probe 13. Under the elastic support of the second spring 45, the arc-shaped push block 26 compresses the second spring 45 through the U-shaped clamping rod 44, causing the arc-shaped clamping block 40 on the U-shaped clamping rod 44 to always apply a gentle opposing clamping force to the guide cover 17, thereby restraining the lateral sway of the probe, ensuring its initial verticality, and absorbing some vibration.

[0045] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The support plate 20 is equipped with a soil-dredging and locking assembly, which is used to assist in fixing the movable base plate 10 to the ground. The soil-dredging and locking assembly includes a rotating cylinder 60, an arc-shaped soil-dredging plate 64, a bidirectional motor 51, a first bevel gear 53, and a second bevel gear 55. The bottom of the movable base plate 10 has movable holes 61 around its perimeter, and a connecting plate 65 is fixedly installed inside the movable holes 61. The bottom of the connecting plate 65 is movably connected to the arc-shaped soil-dredging plate 64 via a rotating shaft, and the arc-shaped soil-dredging plate 64 moves within the movable holes 61. A connecting cylinder 50 is fixedly installed at one end of the movable base plate 10 near the side frame 11. The bidirectional motor 51 is fixedly installed at the center of the connecting cylinder 50. The output end of the bidirectional motor 51 is fixedly installed with a rotating shaft 52, and the first bevel gears 53 are all fixedly installed at the top of the rotating shaft 52. The movable base plate 10 is movably provided with a connecting rod 54. The rotating shaft 52 and the first bevel gears 53 are driven by a single bidirectional motor 51, and the power is distributed to each execution end through the connecting rod 54. This realizes the synchronous control of all arc-shaped excavating plates 64 with a single power source. Its effect is to significantly simplify the transmission system and avoid the problems of coordination asynchrony, high energy consumption or complex control that may be caused by multiple motors.

[0046] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Each movable hole 61 has a rotating cylinder 60 movably installed inside. An S-shaped actuating groove 62 is formed on the outer periphery of the rotating cylinder 60. An arc-shaped actuating rod 63 is movably installed in the S-shaped actuating groove 62 and is fixedly mounted on an arc-shaped soil-removing plate 64. A connecting groove 66 is formed on the connecting plate 65, and the arc-shaped actuating rod 63 movably passes through the connecting groove 66. A connecting rotating rod 54 is connected between the rotating cylinders 60. A second bevel gear 55 is fixedly installed at one end of the connecting rotating rod 54 near the connecting cylinder 50, and the second bevel gear 55 movably interacts with the first bevel gear 53. The bottom of the interlocking, arc-shaped digging plate 64 is fixedly installed with arc-shaped digging nails 67. The arc-shaped digging plate 64 is movably connected to the bottom of the connecting plate 65 through a rotating shaft and is housed in the movable hole 61. During operation, the digging plate is not simply inserted vertically, but moves along a composite trajectory guided by the movable hole 61, which combines downward and outward swinging. This allows the digging nails at the end of the digging plate to cut into the soil layer at the optimal angle. In effect, it achieves digging-type anchoring with low cutting resistance, large gripping depth, and strong pull-out anchoring force, which far exceeds the gripping effect of simply driving vertically.

[0047] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9Using the universal rollers 14 under the movable base plate 10, the auger probe 13 is moved to the position where drilling and exploration are required. The worker rotates the rotating disks 19 around the movable base plate 10, which drives the fixed threaded rod 18 to descend and insert into the soil, thereby achieving stable support and fixation of the movable base plate 10. Then, the soil-digging locking assembly is used to achieve auxiliary positioning support. The bidirectional motor 51 is started, which drives the rotating shaft 52 and the first bevel gear 53 to rotate, which in turn drives the second bevel gear 55 and the connecting rotating rod 54 to rotate. The connecting rotating rod 54 drives the rotating cylinder 60 inside the movable hole 61 to rotate synchronously. The S-shaped actuating groove 62 on the rotating cylinder 60 drives the arc-shaped actuating rod 63 to move, thereby pushing the arc-shaped soil-digging plate 64 to swing downward, so that the arc-shaped soil-digging nail 67 under the arc-shaped soil-digging plate 64 is inserted obliquely into the soil. The arc-shaped soil-digging plate 64 will firmly dig into the ground soil layer, and the movable base plate 10 will be firmly locked in the working position, providing a stable foundation for subsequent precision correction operations.

[0048] Working principle: At the start of the mine drilling and exploration, the universal rollers 14 at the bottom of the movable base 10 are used to move the device to the location where drilling and exploration are needed. The worker rotates the rotating disks 19 around the movable base 10, which drives the fixed threaded rod 18 to descend and insert into the soil, thereby achieving stable support and fixation of the movable base 10. Then, the soil-digging locking component is used to achieve auxiliary positioning support. The bidirectional motor 51 is started, which drives the rotating shaft 52 and the first bevel gear 53 to rotate, which in turn drives the second bevel gear 55 and the connecting rotating rod 54 to rotate. The connecting rotating rod 54 drives the rotating cylinder 60 inside the movable hole 61 to rotate synchronously. The S-shaped actuating groove 62 on the rotating cylinder 60 drives the arc-shaped actuating rod 63 to move, thereby pushing the arc-shaped soil-digging plate 64 to swing downward, so that the arc-shaped soil-digging nail 67 under the arc-shaped soil-digging plate 64 is inserted obliquely into the soil. The arc-shaped soil-digging plate 64 will firmly dig into the ground soil layer, and the movable base 10 will be firmly locked in the working position, providing a stable foundation for subsequent precision correction operations.

[0049] When the sensor detects a deviation in the drilling trajectory of the auger probe 13, the guide correction component will actively correct the deviation. The servo motor 31 will start and drive the support rod 21 to rotate through the first gear 32 and the second gear 22. The second push rod 24 at the top of the support rod 21 will rotate accordingly. The first push rod 23 and the second push rod 24 will cooperate. The first push rod 23 will drive the arc-shaped flip shaft 25 and the arc-shaped push block 26 at the bottom to produce lateral displacement. This will cause the arc-shaped flip shaft 25 to enter the push groove 28 from the flip groove 29. Then, it will flip the arc-shaped push block 26 and continue to move horizontally. The arc-shaped push block 26 will cooperate with the arc-shaped flip shaft 25 to push along the push groove 28. The arc-shaped push block 26 will then drive the arc-shaped clamping block 40 to press against the side of the guide cover 17 of the auger probe 13, applying a precise lateral thrust, forcing the auger probe 13 to gradually return to the predetermined axis.

[0050] When the arc-shaped push block 26 pushes the arc-shaped clamping block 40, the surrounding clamping assembly plays a role in straightening and buffering the auger drill probe 13. Specifically, the hydraulic telescopic pump 12 drives the rotary motor 16 and the auger drill probe 13 to descend for drilling. When the guide cover 17 on the outer periphery of the auger drill probe 13 passes through the drilling hole, it continuously contacts the limiting roller 43 set in the arc-shaped clamping block 40. Under the action of the limiting hole 41 and the first spring 42 in the arc-shaped clamping block 40, the limiting roller 43 achieves flexible clamping and limiting of the auger drill probe 13. Under the elastic support of the second spring 45, the arc-shaped push block 26 compresses the second spring 45 through the U-shaped clamping rod 44, causing the arc-shaped clamping block 40 on the U-shaped clamping rod 44 to always apply a gentle opposing clamping force to the guide cover 17, thereby restraining the lateral sway of the probe, ensuring its initial verticality, and absorbing some vibration.

[0051] When the guiding correction component is working, in order to ensure the effective transmission of the correction thrust and prevent the support plate 20 from shifting, the correction stabilization component operates synchronously. When the servo motor 31 drives the support rotating rod 21 to rotate through the first gear 32 and the second gear 22, the screw 33 at its bottom drives the lifting plate 34 to move vertically downward along the fixed slide 36, pushing the stabilizing cone 35 at its bottom to forcefully insert into the ground. This action reinforces the fixed frame 30 and the support plate 20 connected to it with the ground into a whole, forming a rigid force response fulcrum. This allows the correction force applied by the guiding correction component to act entirely on the auger drill probe 13, greatly enhancing the effectiveness of the correction action and the dynamic stability of the auger drill probe 13. The stabilizing cone 35 is vertically inserted into the ground, firmly fixing the support plate 20. This operation significantly enhances the rigidity of the entire device. The increased rigidity of the device makes the horizontal clamping effect of the arc-shaped clamping block 40 on the guide cover 17 more stable and reliable.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
