Description

Technical Field

[0001] This application relates to the field of deep hole drilling equipment, specifically an integrated equipment for high-efficiency deep hole drilling in mineral exploration. Background Technology

[0002] As mineral exploration and development gradually advances into deeper strata, deep-hole drilling has become a core means of obtaining information on underground mineral resources. Current geological drilling operations face challenges such as complex strata lithology, widespread distribution of hard soil and rock, and high geological stress at depth, leading to continuously increasing demands on the stability, protection, and automation adaptability of drilling equipment. Traditional drilling equipment has a single structural function and mostly adopts a single rotary drilling mode, making it difficult to adapt to the high-efficiency drilling needs of deep and complex strata, resulting in significant shortcomings in overall operational adaptability and efficiency.

[0003] Existing deep-hole drilling equipment suffers from numerous technical deficiencies in actual operation. Conventional drilling rigs lack dedicated buffer and shock-absorbing structures, allowing high-frequency impact vibrations generated during drilling to be directly transmitted to transmission components. This easily leads to eccentric wear of parts, abnormal equipment noise, high failure rates, and short service life. Furthermore, traditional equipment lacks adaptive overload protection structures, making it highly susceptible to drill rod breakage and power head burnout when encountering hard rock jamming conditions. In addition, traditional equipment suffers from poor drill rod alignment accuracy and insufficient locking stability, making drill rod slippage and borehole deviation common in deep-hole operations. Moreover, the drill rod splicing operation is cumbersome and lacks automation, severely restricting the efficiency and safety of deep-hole drilling operations. Summary of the Invention

Example

[0022] Please see the appendix Figure 1 -Appendix Figure 10 This invention provides an integrated deep-hole high-efficiency drilling equipment for mineral exploration, such as... Figure 1As shown, the system includes a base 1, a vertical rail 2 fixedly mounted at the top center of the base 1, a movable platform 3 movably mounted on the front side of the vertical rail 2, a housing 4 fixedly mounted at the front end of the movable platform 3, and a rotating connecting pipe 5 provided in the middle of the housing 4. The base 1 serves as the supporting foundation for the entire drilling equipment, providing stable installation support for all working structures above, ensuring the overall structural stability during equipment operation, and preventing equipment displacement caused by drilling vibrations. The vertical rail 2 provides a vertical sliding guide path for the movable platform 3, restricting the movement trajectory of the movable platform 3 and ensuring that it can only rise and fall smoothly in the vertical direction. The movable platform 3 serves as... The intermediate transmission mounting carrier can drive the housing 4 and the entire internal drilling transmission structure to move vertically synchronously, adapting to the height adjustment requirements of drilling feed operations and drill rod disassembly, assembly, and splicing. The housing 4 serves as a closed protection and positioning installation, protecting the internal rotary transmission, buffering and shock absorption and other core components, isolating them from external dust and gravel interference, and providing fixed installation points for each functional component. The rotary connecting pipe 5 is the core transmission connection component of the equipment, undertaking the core functions of torque transmission, air pressure delivery and drill rod docking, and is the key structure for realizing rotary drilling and air pressure impact operations.

[0023] In this embodiment, a driven gear 11 is provided on the lower outer diameter of the rotary connecting pipe 5, and a compression spring 14 is fixedly installed on the upper outer diameter of the rotary connecting pipe 5, with the end of the compression spring 14 abutting against the upper surface of the driven gear 11. A limiting plate 15 is fixedly installed on the outer diameter of the rotary connecting pipe 5 near the lower position of the driven gear 11. Several semi-circular limiting grooves 16 are evenly opened on the top outer diameter of the limiting plate 15. Several semi-circular limiting pins 17 are evenly fixedly installed on the bottom end of the driven gear 11, with the ends of the semi-circular limiting pins 17 extending into the interior of the corresponding semi-circular limiting grooves 16. The driven gear 11 is a torque transmission driven component, meshing with the driving gear 13 to achieve power transmission, thereby driving the rotary connecting pipe 5 to rotate as a whole. The compression spring 14 always applies downward pressure to the driven gear 11. The clamping force ensures that under normal drilling conditions, the driven gear 11 stably fits against the limiting plate 15, achieving effective torque transmission. The limiting plate 15 is fixed on the rotary connecting pipe 5 and rotates synchronously with it. Through the semi-circular limiting grooves 16 evenly distributed at the top, it forms a locking and limiting structure with the semi-circular limiting pins 17 at the bottom of the driven gear 11. During normal operation, the limiting pins 17 are locked into the limiting grooves 16, realizing synchronous transmission between the driven gear 11 and the rotary connecting pipe 5. When drilling encounters hard rock formations or the drill bit gets stuck and overloaded, the rotary connecting pipe 5 stops moving, and the continuously rotating driven gear 11 will compress the clamping spring 14 upwards, causing the limiting pins 17 to repeatedly disengage and engage with the limiting grooves 16, achieving automatic unloading and stress relief, effectively protecting the power transmission structure and drill rod, avoiding equipment overload damage, and possessing excellent overload protection performance.

[0024] Furthermore, an annular fixing seat 18 is fixedly installed on the front top of the base 1. A central through hole 19 is provided in the middle of the annular fixing seat 18, and a drill rod 31 is provided in the middle of the central through hole 19. A wedge-shaped locking groove 32 is provided on the upper outer diameter of the drill rod 31. The annular fixing seat 18 is fixed to the front end of the base 1, providing a stable mounting base for the drill rod centering and locking structure, ensuring the stability of the drill rod docking operation. The central through hole 19 is the through channel of the drill rod 31, limiting the drilling operation position of the drill rod 31 and ensuring that the drill rod drills vertically. To avoid issues such as deviated or skewed holes in deep hole drilling and improve drilling accuracy, the drill rod 31 is the drilling execution component. The drill bit is installed at the lower end, and the drilling operation is completed through rotation and impact. It can be spliced ​​and lengthened in multiple sections according to the drilling depth requirements to adapt to deep hole mineral exploration operations. The wedge-shaped locking groove 32 set on the outer wall of the drill rod 31 can cooperate with the wedge-shaped locking inclined surface 28 of the centering block 27 to realize the locking of the drill rod, preventing the drill rod from accidentally slipping during deep hole operations or drill rod grafting, and greatly improving operational safety and structural stability.

[0025] Furthermore, the top end of the rotary connecting pipe 5 extends to the top of the housing 4 and is fixedly installed with a high-pressure air pipe 6, while the bottom end of the rotary connecting pipe 5 extends to the bottom of the housing 4 and is fixedly installed with a threaded joint 10. The high-pressure air pipe 6 serves as a channel for transporting pneumatic medium and can be connected to an external high-pressure air supply device to introduce high-pressure air into the rotary connecting pipe 5 and finally into the cavity of the drill rod 31. The high-pressure air can create a pressure difference inside the drill rod 31, driving the heavy-duty piston inside the drill rod to reciprocate rapidly and impact the bottom drill bit at high frequency, forming a pneumatic impact drilling effect, which helps to break hard rock and soil and greatly improves drilling efficiency. The threaded joint 10 is a detachable docking structure with specifications that match the top end of the drill rod 31, which can quickly realize the disassembly and assembly of the rotary connecting pipe 5 and the drill rod 31, facilitating the initial installation of the drill rod, replacement of worn drill rods, and the extension and grafting of drill rods during deep hole operations, adapting to the drilling operation needs of different depths.

[0026] Furthermore, arc-shaped laminated leaf springs 7 are fixedly installed on both the upper and lower sides of the inner shell 4. The outer diameters of the upper and lower sides of the rotary connecting pipe 5 are movably installed in the inner center of the corresponding arc-shaped laminated leaf springs 7 through the mounting bearing rings 8. Limiting brackets 9 are fixedly installed on both sides of the arc-shaped laminated leaf springs 7 for limiting and fixing. The arc-shaped laminated leaf springs 7 are the core shock absorption and buffer components. They adopt a multi-layer leaf spring stacked structure and have excellent buffering and energy absorption effects. During drilling operations, the impact load generated by the drill bit contacting the formation will be transmitted upward to the rotary connecting pipe 5, and then act on the arc-shaped laminated leaf springs 7. The multiple layers of springs can share the impact stress and avoid stress concentration. During the process of deformation under stress, the leaf springs rub against each other, quickly dissipating the impact energy. The spring rebound process is also gentler, effectively isolating the high-frequency impact vibration generated during drilling. The bearing ring 8 is installed to achieve rotational adaptation between the rotating connecting pipe 5 and the arc-shaped laminated leaf spring 7, ensuring that the rotating connecting pipe 5 can rotate freely while stably transmitting vertical impact loads. The limiting frame 9 limits and fixes the arc-shaped laminated leaf spring 7 on both sides to prevent the leaf spring from shifting under stress or loosening, ensuring the long-term stable operation of the shock absorption structure, effectively reducing the eccentric wear and abnormal noise of the rotating parts of the equipment, reducing the equipment failure rate, and extending the overall service life of the equipment.

[0027] Furthermore, power heads 12 are fixedly installed on both sides of the top of the housing 4. The driving ends of the power heads 12 extend into the interior of the housing 4 and are fixedly installed with drive gears 13. The inner ends of the drive gears 13 are respectively meshed with the two sides of the driven gears 11. The power heads 12, which are symmetrically arranged on both sides, provide rotational power for the drilling equipment. The dual-power structure outputs more stable torque and more sufficient power, which can meet the high torque operation requirements of drilling in hard strata and deep holes. The power heads 12 drive the drive gears 13 to rotate continuously. The drive gears 13 on both sides mesh synchronously to transmit the driven gears 11, realizing a smooth power output. The symmetrical meshing transmission method can balance the force on the driven gears 11, avoid the transmission eccentricity and jamming problems caused by unilateral force, ensure that the rotating connecting pipe 5 rotates at a uniform speed and stably, and make the drill rod 31 rotate more smoothly, improving the drilling operation accuracy and stability, and adapting to long-term, high-intensity mineral exploration drilling work.

[0028] Furthermore, the annular fixed base 18 has an inner cavity 20. A worm gear 21 is movably installed at the bottom of the inner cavity 20, and a driving bevel gear 22 is fixedly installed at the top of the worm gear 21. Threaded rods 23 are movably installed around the inner sidewalls of the inner cavity 20. Driven bevel gears 24 are fixedly installed on the outer diameter of the threaded rods 23 near the central through hole 19, and the bottom ends of the driven bevel gears 24 are meshed with the top of the driving bevel gears 22. The inner cavity 20 provides a closed installation space for the internal transmission components, protecting the worm gear 21 and the bevel gear 22. Precision transmission structures such as gears and threaded rods 23 prevent impurities from affecting transmission accuracy. The worm gear 21 and the driving bevel gear 22 are fixed as a single unit and can rotate synchronously to achieve power steering and diversion. Multiple sets of threaded rods 23 are evenly distributed around the central through hole 19. Through the meshing of the driven bevel gear 24 and the driving bevel gear 22, all threaded rods 23 can rotate synchronously in the same direction, providing stable power support for the linkage movement of the subsequent drill rod centering and locking structure, ensuring that multi-directional adjustment actions are synchronous, precise, and without movement deviation.

[0029] Furthermore, each threaded rod 23 has a bent rod 25 threadedly connected to its outer diameter on the side away from the central through hole 19. A guide rod 26 is fixedly installed on the upper side of the inner cavity 20 near each threaded rod 23, with the end of each guide rod 26 extending into the corresponding bent rod 25. The inner end of each bent rod 25 extends into the central through hole 19 and is fixedly fitted with a centering block 27. The inner end of each centering block 27 has a wedge-shaped locking slope 28. When the threaded rod 23 rotates, it drives the bent rod 25 to perform horizontal extension and retraction based on the threaded transmission principle. The guide rod 26 precisely limits and guides the bent rod 25, restricting its rotational freedom and ensuring the bending... The bent rod 25 can only move smoothly back and forth in the horizontal direction to avoid movement deviation and jamming. Multiple sets of bent rods 25 simultaneously retract inward or open outward, driving the centering block 27 to move synchronously. When retracting inward, it can automatically center and correct the drill rod 31 in the central through hole 19, ensuring that the drill rod is always in the center of the borehole. The wedge-shaped locking slope 28 on the inner side of the centering block 27 is precisely matched with the wedge-shaped locking groove 32 of the drill rod 31. After fitting and locking, it can firmly lock the drill rod 31, restrict the vertical sliding of the drill rod, completely eliminate the risk of the drill rod slipping and falling off during deep hole operation and drill rod grafting, and greatly improve the safety and stability of deep hole drilling operation.

[0030] Furthermore, a geared motor 29 is fixedly installed on one side of the base 1. The drive end of the geared motor 29 extends into the interior of the inner cavity 20 and is fixedly installed with a worm gear 30. The worm gear 30 is meshed with the inner end of the worm wheel 21. The geared motor 29 provides dedicated drive power for the drill rod centering and locking mechanism, and can output stable low-speed torque, which is suitable for precision centering adjustment operations. The worm gear 30 and the worm wheel 21 form a worm gear transmission structure, which has the advantages of smooth transmission and strong self-locking. It can precisely drive the worm wheel 21 and the active bevel gear 22 to rotate, realize the drill rod centering and locking adjustment, and realize the structure self-locking after the adjustment is completed, so as to avoid the transmission structure from reversing and loosening during operation, and ensure the long-term stability of the drill rod centering and locking state. It does not require continuous power supply for locking, is energy-saving and highly reliable.

[0031] Furthermore, a hydraulic pulley assembly 33 is installed on the rear side of the vertical rail 2, and a suspension mounting frame 34 is fixedly installed on the rear side of the base 1. The suspension mounting frame 34 is a structure for overall hoisting and traction installation of the equipment, which can conveniently fix the entire drilling equipment on the traction equipment, facilitate on-site transportation and quick positioning of the equipment, adapt to the mobile operation needs of field mineral exploration, and has extremely strong site adaptability. The hydraulic pulley assembly 33 and the movable platform 3 work together to output stable hydraulic feed pressure. When drilling encounters hard rocks or hard soil, causing the drill bit to get stuck and the breaking efficiency to be low, the hydraulic pressure drives the movable platform 3 to feed downward, providing stable downward pressure to the drill rod 31, assisting the drill bit to efficiently break hard strata, overcoming the drilling stuck problem, and greatly improving the breaking efficiency and operational adaptability of deep hole drilling.

[0032] Working principle: The equipment is mounted and fixed on the tractor by the suspension mounting bracket 34. The tractor moves the equipment to the predetermined position. After determining the drilling position, the initial drill rod 31 is installed through the threaded joint 10. The end of the drill rod 31 passes through the central through hole 19 and touches the ground. Then, the power head 12 is started. The power head 12 drives the drive gear 13 to rotate. The drive gear 13 drives the driven gear 11 and the rotating connecting pipe 5 to rotate through meshing transmission, thereby driving the drill rod 31 to rotate. At the same time, high-pressure air is introduced into the high-pressure air pipe 6. The high-pressure air enters the interior of the initial drill rod 31 and forms a pressure difference in the upper and lower chambers inside the initial drill rod 31. This causes the internal heavy piston to move up and down rapidly, hitting the drill bit at the bottom of the initial drill rod 31 at high speed, thus starting to drill a hole in the ground.

[0033] During drilling, the impact load during drilling is transmitted to the rotary connecting pipe 5. At this time, the strong impact force will cause the arc-shaped laminated leaf spring 7 to deform, so that each leaf will share the impact force. The leaves between the arc-shaped laminated leaf spring 7 will quickly rub against each other to eliminate a large amount of energy. The large impact force will also make the rebound of the arc-shaped laminated leaf spring 7 more gentle, effectively isolating the impact vibration transmitted from the drill bit, reducing the eccentric wear and abnormal noise of the rotating parts, reducing the failure rate, and extending the service life.

[0034] When encountering hard rock or soil, the drill bit at the bottom of the initial drill rod 31 may get stuck. This is because the rotation of the drive gear 13 does not directly drive the rotary connecting pipe 5 via the driven gear 11. Instead, the drive gear 13 rotates by engaging the semi-circular limiting pin 17 at the bottom of the driven gear 11 into the semi-circular limiting groove 16 via the compression spring 14. This, in turn, drives the rotating connecting pipe 5 by rotating the limiting plate 15. If the drill bit gets stuck, the drill rod 31 and the rotary connecting pipe 5 will stop rotating, and the drive gear 13 and the driven gear 11 will continue to rotate. While the machine is still rotating normally, the driven gear 11 will compress the spring 14 upwards, causing the semi-circular limiting groove 16 and the semi-circular limiting pin 17 to continuously engage and disengage. At this time, the driven gear 11 will no longer apply rotational force to the rotating connecting pipe 5, which can protect the power head 12 and the drill rod 31. At this time, the hydraulic pulley assembly 33 on the rear side will start, and the hydraulic pressure will act on the entire rotating connecting pipe 5 through the pulley assembly and the movable table 3, applying sufficient hydraulic pressure to the drill rod 31 to improve the crushing efficiency.

[0035] When an additional drill rod 31 is needed, the power head 12 first drives the rotating connecting pipe 5 to reverse, causing the rotating connecting pipe 5 to disengage from the previous drill rod 31. Then, the movable table 3 rises and resets. At this time, the reduction motor 29 is started, which drives the worm gear 30 to rotate, thereby driving the worm wheel 21 and the driving bevel gear 22 to rotate. The rotating driving bevel gear 22 will drive all the driven bevel gears 24 and the threaded rod 23 to rotate. When the threaded rod 23 rotates, the guide rod 26 limits the movement of all the bending rods 25 and the centering block 27 to move inward synchronously, thereby pushing the top of the previous drill rod 31 to the center position. At the same time, when the centering block 27 moves inward, the wedge-shaped locking slope 28 on the inner side will be locked into the wedge-shaped locking groove 32 on the outer surface of the drill rod 31 to prevent the deep hole drill rod 31 from accidentally slipping off. Then, the new drill rod 31 is placed between the old drill rod 31 and the threaded joint 10. The previous steps are repeated to complete the grafting of the new drill rod 31.

[0036] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
