Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and in particular to an anti-overturning anchoring device. Background Technology

[0002] In scenarios such as oil exploration, geological sampling, and geotechnical engineering, vibrations, eccentric loads, and sudden impacts generated during drilling operations can easily cause equipment to overturn. Especially in high-risk operation scenarios such as slopes, frozen soil, or alternating soft and hard strata, the stability of the anchoring device directly determines the safety and efficiency of construction.

[0003] Traditional anchoring devices rely on passive anti-overturning structures (such as rigid anchor bolts and counterweights), which cannot detect overturning moment fluctuations caused by drilling rig vibrations in real time. For example, under conditions of a sudden increase in drilling torque, the lateral load on the anchor bolt can rise to a critical value within 0.5 seconds, while the response time for manual intervention is usually more than 3 seconds, leading to overload failure of the anchoring system. Although some improved solutions have introduced sensors, they only provide early warning signals and do not form a closed-loop control with the actuators (such as power cut-off and emergency expansion of the anchor claws). Sudden risks still require manual operation, posing serious safety hazards.

[0004] In summary, existing anchoring devices have significant shortcomings in terms of dynamic load response speed, intelligent control level, adaptability to complex environments, and human-machine collaborative safety.

[0005] Therefore, there is an urgent need for an anti-overturning anchoring device to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide an anti-overturning anchoring device to solve the problems existing in the prior art, which can prevent the anchor rod from overloading and causing the whole overturning, ensure the overall stability of the device, and realize the functions of automatic anti-overturning and anti-torsion.

[0007] To achieve the above objectives, the present invention provides the following solution: This invention provides an anti-overturning anchoring device, comprising a support structure, a drive motor, a clutch, a dynamic torque sensor, an anchor rod, and a linkage control system. The drive motor is fixed to the support structure, and the output shaft of the drive motor is connected to the input end of the clutch. The output end of the clutch is connected to the dynamic torque sensor, and the lower end of the dynamic torque sensor is connected to the anchor rod. The anchor rod is threadedly connected to the support structure. The linkage control system is electrically connected to the dynamic torque sensor and the clutch. The linkage control system can acquire the torque data of the anchor rod in real time through the dynamic torque sensor, and when the torque of the anchor rod exceeds a preset safety threshold, it controls the clutch to cut off the power transmission of the anchor rod.

[0008] Preferably, the support structure includes a housing, with legs at the bottom of the housing, the drive motor fixed to the top of the housing, and a fixing bracket inside the housing, with the anchor rod threadedly connected to the fixing bracket.

[0009] Preferably, the bottom of the housing is provided with a through hole for the anchor rod to pass through.

[0010] Preferably, multiple anchor rods are provided, and multiple clutches and dynamic torque sensors are provided accordingly. The output end of any clutch is connected to a dynamic torque sensor, and the lower end of any dynamic torque sensor is connected to an anchor rod.

[0011] Preferably, the clutch is connected to the dynamic torque sensor via a coupling.

[0012] Preferably, the clutch is an electromagnetic friction clutch; The electromagnetic friction clutch is a dry multi-plate clutch. When the power is off, the dry multi-plate clutch separates the active friction plate group and the driven friction plate group through a return spring. The power-off response time of the dry multi-plate clutch is ≤0.1 seconds.

[0013] Preferably, the lower end of the dynamic torque sensor is connected to a sensor gear, and the top end of the anchor rod is connected to an anchor rod gear. The sensor gear meshes with the anchor rod gear, thereby enabling the anchor rod to rotate.

[0014] Preferably, the dynamic torque sensor is a magnetoelastic sensor, which has a built-in temperature compensation module to correct zero-point drift caused by changes in ambient temperature, and the sampling frequency of the magnetoelastic sensor is ≥1KHz.

[0015] Preferably, the anchor rod has a hollow structure, and a helical blade is provided at the lower end of the anchor rod, with anti-slip texture on the surface of the helical blade.

[0016] Preferably, the output shaft of the drive motor is connected to a drive gear, and the input end of the clutch is connected to a driven gear, with the drive gear meshing with the driven gear.

[0017] The present invention achieves the following technical effects compared to the prior art: The anti-overturning anchoring device of this invention mainly includes a support structure, a drive motor, a clutch, a dynamic torque sensor, an anchor rod, and a linkage control system. The support structure is used to support the ground. The drive motor is fixed to the support structure, specifically to the top of the support structure. The output shaft of the drive motor is connected to the input end of the clutch. The output end of the clutch is connected to the dynamic torque sensor. The lower end of the dynamic torque sensor is connected to the anchor rod. The anchor rod is threadedly connected to the support structure.

The linkage control system can obtain the torque data of the anchor rod in real time through the dynamic torque sensor, and when the torque of the anchor rod exceeds a preset safety threshold, it controls the clutch to cut off the power transmission of the anchor rod.

[0018] In this invention, the drive motor can drive the input end of the clutch to rotate. At this time, the clutch is energized and transmits power to its output end. Subsequently, the power is transmitted to the anchor rod through the dynamic torque sensor, causing the anchor rod to rotate synchronously and realize drilling.

[0022] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The purpose of this invention is to provide an anti-overturning anchoring device to solve the problems existing in the prior art, which can prevent the anchor rod from overloading and causing the whole overturning, ensure the overall stability of the device, and realize the functions of automatic anti-overturning and anti-torsion.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 like Figures 1-3 As shown, this embodiment provides an anti-overturning anchoring device, mainly including a support structure, a drive motor 1, a clutch, a dynamic torque sensor 6, an anchor rod 9, and a linkage control system 13. The support structure is used to support the ground. The drive motor 1 is fixed to the support structure, specifically to the top of the support structure. The output shaft of the drive motor 1 is connected to the input end of the clutch. The output end of the clutch is connected to the dynamic torque sensor 6. The lower end of the dynamic torque sensor 6 is connected to the anchor rod 9. The anchor rod 9 is threadedly connected to the support structure. The linkage control system 13 is electrically connected to the dynamic torque sensor 6 and the clutch. The linkage control system 13 can obtain the torque data of the anchor rod 9 in real time through the dynamic torque sensor 6, and when the torque of the anchor rod 9 exceeds a preset safety threshold, it controls the clutch to cut off the power transmission of the anchor rod 9.

[0026] In this embodiment, the drive motor 1 can drive the input end of the clutch to rotate. At this time, the clutch is energized and transmits power to its output end. Then, the power is transmitted to the anchor rod 9 through the dynamic torque sensor 6, which drives the anchor rod 9 to rotate synchronously and realize drilling. When the anchor rod 9 drills into the rock or encounters other situations that cause the torque of the anchor rod 9 to exceed the preset safety threshold of the dynamic torque sensor 6, the dynamic torque sensor 6 will transmit the torque signal to the linkage control system 13. The linkage control system 13 will cut off the power supply to the clutch in time, disconnect the power transmission of the anchor rod 9, prevent overload from causing the whole overturning, ensure the overall stability of the device, and realize the functions of automatic anti-overturning and anti-reverse torque.

[0027] In this embodiment, the support structure can be selected according to specific working needs. As one possible implementation, the support structure may include a housing 11, with legs 12 at the bottom of the housing 11 for easy support on the ground. The drive motor 1 can be fixed to the top of the housing 11. A fixing bracket 10 is also provided inside the housing 11. The anchor rod 9 is threadedly connected to the fixing bracket 10. Specifically, the outer wall of the anchor rod 9 is provided with drilling threads, and the fixing bracket 10 is provided with a threaded hole. The inner wall of the threaded hole is provided with an internal thread that mates with the drilling threads. The anchor rod 9 passes through the threaded hole and is threadedly connected to the fixing bracket 10, so that the anchor rod 9 can move up and down relative to the housing 11 when it rotates. The bottom of the housing 11 is also provided with a through hole for the anchor rod 9 to pass through.

[0028] The housing 11 can be a cuboid structure, and each of the four corners of the bottom of the housing 11 is provided with a leg 12, and the leg 12 is inclined outward to improve the stability of the support; the fixed bracket 10 can be an L-shaped bracket, with its two ends fixedly connected to the housing 11, and the threaded hole is provided at the middle corner.

[0029] In this embodiment, multiple anchor rods 9 can be provided, and multiple clutches and dynamic torque sensors 6 can be provided accordingly. The output end of any clutch is connected to a dynamic torque sensor 6, and the lower end of any dynamic torque sensor 6 is connected to an anchor rod 9. Multiple anchor rods 9 can be controlled independently. When the power transmission of one anchor rod 9 is disconnected, the other normally drilling anchor rods 9 are not affected. Through the independent control of multiple anchor rods 9 and the rapid clutch mechanism, the overall overturning caused by local overload is prevented, ensuring the overall stability of the device and realizing the functions of automatic anti-overturning and anti-reverse torque.

[0030] As one possible implementation, four anchor bolts 9 may be provided, and the four anchor bolts 9 may be distributed in a rectangular array; however, it should be noted that the number of anchor bolts 9 is not limited to four, and other numbers of anchor bolts 9 may be selected as needed, such as two, six, etc.

[0031] In this embodiment, the clutch is connected to the dynamic torque sensor 6 via a coupling 5. The coupling 5 ensures the accuracy of the dynamic torque sensor 6 and also protects it from damage due to overload.

[0032] In this embodiment, the clutch can be selected as needed. As a preferred implementation, the clutch can be an electromagnetic friction clutch 4. Further, the electromagnetic friction clutch 4 can be a dry multi-plate clutch, which separates the active friction plate group and the driven friction plate group by a return spring when the power is off, and the power off response time is ≤0.1 seconds.

[0033] In this embodiment, the lower end of the dynamic torque sensor 6 is connected to the sensor gear 7, and the top end of the anchor rod 9 is connected to the anchor rod gear 8. The sensor gear 7 meshes with the anchor rod gear 8, thereby driving the anchor rod 9 to rotate. The lower end of the anchor rod gear 8 has a spline structure and is connected to the anchor rod 9 by a spline.

[0034] In this embodiment, the dynamic torque sensor 6 can be a magnetoelastic sensor. The magnetoelastic sensor has a built-in temperature compensation module to correct zero-point drift caused by changes in ambient temperature. The sampling frequency of the magnetoelastic sensor is ≥1 kHz.

[0035] In this embodiment, the anchor rod 9 has a hollow structure, which can significantly reduce the overall weight and facilitate the miniaturization and mobility of the device, making it particularly suitable for environments where transportation is inconvenient, such as mountains and slopes. The lower end of the anchor rod 9 is equipped with a helical blade, which can push the surrounding soil or rock debris upwards when the anchor rod 9 rotates and drills, and enhance the interlocking force and pull-out resistance between the anchor rod 9 and the soil. The surface of the helical blade is provided with anti-slip grooves to increase the friction coefficient with the soil, prevent slippage in hard rock or frozen soil, and improve anchoring efficiency.

[0036] In this embodiment, the output shaft of the drive motor 1 is connected to a drive gear 2, and the input end of the clutch is connected to a driven gear 3. The drive gear 2 meshes with the driven gear 3, thereby enabling the drive motor 1 to drive the input ends of the four clutches to rotate.

[0037] In this embodiment, the linkage control system 13 can be selected according to specific working needs. For example, it can be a PLC controller or an integrated mechatronics controller, which are mature technologies in this field and will not be described in detail in this embodiment.

[0038] The working principle of the anti-overturning anchoring device in this embodiment is as follows: In actual use, the drive motor 1 drives the active gear 2 to rotate. During the rotation of the active gear 2, the active gear 2 drives four driven gears 3 to rotate synchronously. The lower end of the driven gears 3 is connected to the electromagnetic friction clutch 4. The driven gears 3 drive the input shaft of the electromagnetic friction clutch 4 to rotate. At this time, the electromagnetic friction clutch 4 is energized, and its active friction plate group and driven friction plate group are tightly engaged, transmitting power to the output end of the electromagnetic friction clutch 4. The electromagnetic friction clutch 4 is connected to the dynamic torque sensor 6 through the coupling 5. The coupling 5 has the function of ensuring the accuracy of the dynamic torque sensor 6, and at the same time, it also plays a protective role, preventing the dynamic torque sensor 6 from being damaged due to overload. Then, the dynamic torque sensor 6 transmits power to the sensor gear 7. The sensor gear 7 drives the anchor rod gear 8 to rotate synchronously. The lower end of the anchor rod gear 8 has a spline structure and is connected to the anchor rod 9 by a spline. During the rotation of the anchor rod gear 8, it drives the anchor rod 9 to rotate synchronously. The outer wall of the anchor rod 9 is provided with a drilling thread, which engages with the threaded hole on the fixed bracket 10. When the anchor rod gear 8 rotates, the anchor rod 9 realizes the downward drilling action.

[0039] During the drilling process of the device, when one or more anchor bolts 9 drill into the rock or encounter other situations that cause the torque of the anchor bolt 9 to exceed the preset safety threshold of the dynamic torque sensor 6, the dynamic torque sensor 6 will transmit the torque signal to the linkage control system 13. The linkage control system 13 will cut off the power supply of the electromagnetic friction clutch 4 in time, disconnecting the power transmission of the anchor bolt 9. Other anchor bolts 9 that are drilling normally will not be affected. Through the independent control of multiple anchor bolts 9 and the rapid clutch mechanism, the overall overturning caused by local overload is prevented, ensuring the overall stability of the device and realizing the functions of automatic anti-overturning and anti-reverse torque.

[0040] This invention solves the problems of traditional anchoring devices relying on passive load resistance and slow response. It also features miniaturization and high reliability, making it suitable for complex geological environments such as mountains and permafrost, and significantly improving the safety of drilling operations and the stability of equipment.

[0041] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
