Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to an energy-saving drilling device and process for mine geological exploration. Background Technology

[0002] Drilling for geological exploration in mines is a core component of the entire mineral exploration and development process. Its purpose is to directly and accurately obtain underground rock core samples, determine the morphology, scale, occurrence, grade, and spatial distribution of the ore body, and provide crucial information for reserve calculation, mine design, and mining plan formulation. To improve coring efficiency, wireline coring drilling equipment has been designed, which allows for the direct retrieval of the sampling inner tube using a retrieval tool without removing the outer drilling casing, thereby extracting the sample.

[0003] Currently, when wireline coring drilling equipment is used to increase the drilling depth, operators need to manually loosen the rotary head and drill rod, and then manually install new drill rods. Due to safety factors, personnel need to stay away from the equipment while it is in operation. In addition, the manual loosening of the drill rod and rotary head and the installation of new drill rods result in long idle waiting times and high energy consumption. Energy consumption during this period needs to be reduced. Summary of the Invention

[0004] The purpose of this invention is to address the problems of long installation time for new drill rods, long idle waiting time for equipment, and high energy consumption in the prior art, and to propose an energy-saving mining geological exploration drilling device and process.

[0005] On one hand, this invention proposes an energy-saving drilling device for mining geological exploration, including a wireline coring drill body, a lifting seat slidably mounted on the tower, a power head mounted on the lifting seat, a rotary head mounted at the bottom of the power head, and a drill rod threadedly connected to the top of the rotary head at the bottom; a self-disassembly mechanism is provided at the bottom of the tower, which clamps the drill rod and the rotary head after the rotary head descends to the lowest point and causes them to rotate relative to each other, thereby loosening the drill rod and the rotary head; a self-filling mechanism is provided on the side of the tower, after the rotary head separates from the drill rod and rises to the highest point, the self-filling mechanism moves another drill rod to directly above the drill rod that has been driven into the ground and connects the two drill rods, and then the rotary head descends and rotates to connect with the top of the newly inserted drill rod.

[0006] Preferably, the self-disassembly mechanism clamps the drill rod and rotary head from both sides and drives the drill rod to rotate at a set angle to loosen it.

[0007] Preferably, the self-disassembly mechanism includes two clamping assemblies symmetrical about the drill pipe. Each clamping assembly includes a slide rail disposed on the side of the tower, a clamping frame slidably disposed on the slide rail, a rotary head clamping plate and an arc plate disposed on the clamping frame, and a drill pipe clamping plate rotatably disposed on the inner wall of the arc plate. A telescopic device a is provided in the slide rail to drive the clamping frame to move.

[0008] Preferably, an arc-shaped gear ring is provided on the outer wall of the drill pipe clamping plate, a power device a is provided on the clamping frame, and a gear is provided on the output shaft of the power device a, the gear meshing with the arc-shaped gear ring.

[0009] Preferably, the self-filling mechanism includes a tilting frame rotatably disposed on the side of the tower, a support plate disposed on the tilting frame, a slide plate slidably disposed on the support plate in a vertical direction, and multiple grippers disposed on the slide plate. The slide plate is provided with a rotating component that drives the drill rod to be filled to rotate, and the support plate is provided with a lifting component that drives the slide plate to move up and down.

[0010] Preferably, the rotating assembly includes two rollers rotatably mounted on the slide plate, and a power device c mounted on the top of the slide plate to drive the two rollers to rotate synchronously. When the drill rod is clamped by the chuck, it abuts against the two rollers. Multiple balls are rotatably mounted on the inner wall of the chuck, and the balls are in rolling connection with the drill rod.

[0011] Preferably, the lifting assembly includes multiple springs disposed on the top of the power unit c, a flat plate disposed on the top of the springs, a mounting bracket disposed on the top of the support plate, and a telescopic device c vertically disposed on the mounting bracket, the bottom of the telescopic end of the telescopic device c being connected to the flat plate.

[0012] On the other hand, the present invention proposes a drilling process for mine geological exploration, comprising the following steps: S1. After connecting a drill rod to the rotary head, the drill rod is rotated and driven into the ground by the power head and the rotary head until the rotary head moves to the lowest point; S2. The self-disassembly mechanism clamps the drill rod and the rotary head and makes them rotate relative to each other. The drill rod is loosened, and the rotary head rotates in the opposite direction, disengaging from the drill rod and moving upward to the highest point. S3. The self-filling mechanism moves another drill pipe directly above the drill pipe that has been driven into the ground and connects the two drill pipes. S4. The rotary head descends and rotates to connect with the top of the newly inserted drill pipe. The self-filling mechanism resets, and the power head and rotary head move down to continue drilling.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: when the drill rod needs to be extended at the designated position, the operator does not need to go close to manually loosen the rotary head and drill rod, nor does the operator need to manually pick up the drill rod for manual installation. All of these are completed quickly by the self-disassembly mechanism and the self-filling mechanism. The idle waiting time of the entire equipment is very short, and the safety is also higher. Under the same workload, it can greatly improve work efficiency and energy saving effect of the equipment. Attached Figure Description

[0015] Example 1; as Figure 1As shown, this invention proposes an energy-saving mining geological exploration drilling device, comprising a wireline coring drill body 1, a lifting seat 3 slidably mounted on a tower 2, a power head 4 mounted on the lifting seat 3, and a rotary head 5 mounted at the bottom of the power head 4. The bottom of the rotary head 5 is threadedly connected to the top of a drill rod 7, which passes through a positioning disc 6 on the wireline coring drill body 1. This part of the structure is a conventional structure of existing wireline coring drilling equipment on the market and is not the core of this application; therefore, the specific structure and working principle will not be described in detail. A self-disassembly mechanism is provided at the bottom of the tower 2. After the rotary head 5 descends to its lowest point, the self-disassembly mechanism clamps the drill rod 7 and the rotary head 5, causing them to rotate relative to each other, thereby loosening the drill rod 7 and the rotary head 5. Subsequently, the rotary head 5 rotates in the opposite direction and rises on its own, quickly completing the separation of the rotary head 5 and the drill rod 7. The tower 2 is equipped with a self-disassembly mechanism at its side. After the rotary head 5 separates from the drill rod 7 and rises to its highest point, the self-filling mechanism moves another drill rod 7 to directly above the drill rod 7 that has already been driven into the ground and connects the two drill rods 7. Then, the rotary head 5 descends and rotates to connect with the top of the newly inserted drill rod 7. Finally, the self-filling mechanism withdraws from the working area of ​​the lifting seat 3 and the power head 4, and the rotary head 5 rotates to continue drilling downwards. In this application, when the drill rod 7 needs to be extended at a designated position, it is not necessary for the operator to approach and manually loosen the rotary head 5 and the drill rod 7, nor is it necessary for the operator to manually pick up the drill rod 7 for manual installation. All of these are quickly completed by the self-disassembly mechanism and the self-filling mechanism. The idling waiting time of the entire equipment is very short, and the safety is also higher. Under the same workload, it can significantly improve work efficiency and energy saving effect of the equipment.

[0016] Furthermore, the self-disassembly mechanism clamps the drill rod 7 and the rotary head 5 from both sides and drives the drill rod 7 to rotate at a set angle to loosen it. In this application, the angle of the drill rod 7 rotating in the opposite direction is 20°-30°. The entire process of the self-disassembly mechanism from the start of action to the completion of disassembly and resetting only takes ten seconds. If a person were to manually loosen it, ten seconds would barely be enough for the operator to walk to the vicinity of the equipment.

[0017] Example 2; as Figure 4As shown, this invention proposes an energy-saving mining geological exploration drilling device. Compared with Embodiment 1, this embodiment details the structure of the self-disassembly mechanism. Specifically, the self-disassembly mechanism includes two clamping components symmetrical about the drill rod 7. The clamping components include a slide rail 8 set on the side of the tower 2, a clamping frame 9 slidably set on the slide rail 8, a rotary head clamping plate 11 and an arc plate 12 set on the clamping frame 9, and a drill rod clamping plate 13 rotatably set on the inner wall of the arc plate 12. A telescopic device a10 is provided in the slide rail 8 to drive the clamping frame 9 to move. The telescopic device a10 is a cylinder. When performing the self-disassembly action, the telescopic device a10 first moves to push the clamping frame 9 closer to the drill rod 7 and the rotary head 5, and clamps the rotary head 5 and the drill rod 7 through the rotary head clamping plate 11 and the drill rod clamping plate 13.

[0018] Furthermore, an arc-shaped gear ring 14 is provided on the outer wall of the drill pipe clamping plate 13, and a power device a16 is provided on the clamping frame 9. A gear 15 is provided on the output shaft of the power device a16, and the gear 15 meshes with the arc-shaped gear ring 14. The power device a16 consists of a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the gear 15 is provided on the output shaft of the reducer. When the rotary head 5 and the drill pipe 7 are clamped, the motor works, and the gear 15 drives the arc-shaped gear ring 14 and the drill pipe clamping plate 13 to rotate at a set angle, thereby loosening the drill pipe 7. It should be noted that when performing the self-disassembly action, the rotary head 5 has a certain amount of movement in the vertical direction.

[0019] Example 3; as Figures 2-6As shown, this invention proposes an energy-saving mining geological exploration drilling device. Compared with Embodiment 1, this embodiment details the structure of the self-filling mechanism. Specifically, the self-filling mechanism includes a tilting frame 17 rotatably mounted on the side of the tower 2, a support plate 20 mounted on the tilting frame 17, a sliding plate 21 slidably mounted on the support plate 20 in the vertical direction, and multiple grippers 23 mounted on the sliding plate 21. The sliding plate 21 is equipped with a rotating component that drives the drill rod 7 to be filled to rotate. The support plate 20 is equipped with a lifting component that drives the sliding plate 21 to move up and down. To facilitate the operator in placing the drill rod 7 to be added, a support plate 35 is provided on the tower 2. When placing the drill rod 7, it is only necessary to press the bottom of the drill rod 7 onto the support plate 35. When the tilting frame 17 rotates forward, the drill rod 7 will automatically disengage from the support plate 35. The drill rod 7 rotates and moves down to achieve a preliminary connection with the drill rod 7 that has already been drilled underground. The subsequent rotation of the rotary head 5 will complete the final tightening. The grippers 23 are set on a... A rotating rod 22 is rotatably mounted on a fixed base 24, which is mounted on a sliding plate 21. A connecting frame 27 is mounted on the rotating rod 22, and a telescopic device b28 is mounted on the sliding plate 21 to push the connecting frame 27 and the rotating rod 22 to rotate. It should be noted that the telescopic end of the telescopic device b28 is not connected to the connecting frame 27, but only in contact. The telescopic device b28 is a cylinder. A limiting ring 25 is mounted on the rotating rod 22, and a torsion spring 26 is fitted on the rotating rod 22. 6 provides reset power for the gripper 23. When the telescopic device b28 extends, the gripper 23 clamps the drill rod 7. When the telescopic device b28 retracts, the gripper 23 flips and resets. In an optional embodiment, a power device b19 is provided on the tower 2. The output shaft of the power device b19 is connected to a support column 18. The flipping frame 17 is connected to the support column 18. It should be noted that the flipping frame 17 has a U-shaped structure and is located on one side of the tower 2 when not in operation, and does not affect the lifting of the lifting seat 3 and the rotary head 5.

[0020] Furthermore, the rotating assembly includes two rollers 29 rotatably mounted on the slide plate 21, and a power device c30 mounted on the top of the slide plate 21 to drive the two rollers 29 to rotate synchronously. The power device c30 has a conventional structure, such as a combination of a motor and a reducer to drive one of the rollers 29 to rotate. The two rollers 29 are connected by a sprocket and a chain. The specific combination will not be described in detail. When the drill rod 7 is clamped by the chuck 23, it rests against the two rollers 29. Multiple balls are rotatably mounted on the inner wall of the chuck 23. The balls are rolledly connected to the drill rod 7. The rotation of the rollers 29 can drive the rotation of the drill rod 7.

[0021] Furthermore, the lifting assembly includes multiple springs 31 mounted on top of the power unit c30, a flat plate 32 mounted on top of the springs 31, a mounting bracket 34 mounted on top of the support plate 20, and a telescopic device c33 vertically mounted on the mounting bracket 34. The bottom of the telescopic end of the telescopic device c33 is connected to the flat plate 32. The telescopic device c33 is a cylinder. The telescopic device c33 can push the entire slide plate 21 and the structure on the slide plate 21 to move downward, thereby driving the drill rod 7 to move downward. The drill rod 7 rotates while moving downward, thereby completing a preliminary threaded connection with the drill rod 7 that has been driven into the ground. The springs 31 can balance the mismatch between the extension speed of the telescopic device c33 and the downward speed of the drill rod 7.

[0022] Example 4; The present invention proposes a drilling technology for mine geological exploration, which uses the energy-saving drilling device of Example 3, and specifically includes the following steps: S1. After connecting a drill rod 7 to the rotary head 5, the drill rod 7 is rotated and driven into the ground through the power head 4 and the rotary head 5 until the rotary head 5 moves to the lowest point. S2. The self-disassembly mechanism clamps the drill rod 7 and the rotary head 5 and makes them rotate relative to each other. The drill rod 7 is loosened, and the rotary head 5 rotates in the opposite direction, disengaging from the drill rod 7 and moving up to the highest point. S3. The self-filling mechanism moves another drill rod 7 to directly above the drill rod 7 that has been driven into the ground and connects the two drill rods 7. S4. The rotary head 5 descends and rotates to connect with the top of the newly inserted drill rod 7. The self-filling mechanism resets, and the power head 4 and rotary head 5 move down to continue drilling.

[0023] Supplementary explanation regarding cylinder air connection: In this application, telescopic devices a10, b28, and c33 are all cylinders. All cylinders are supplied with air using the original equipment's air compressor. However, this is not a simple matter of connecting a pipe; a complete and systematic process and modification are required, mainly involving the following four steps: The first step is to obtain and isolate the air source: On the main air line of the drilling rig, after the air compressor outlet and the main air consumption point of the original equipment, a suitable branch point must be selected and led out through a three-way connector. A manual or automatic ball valve must be installed immediately so that the air line can be completely cut off during maintenance of the new air line without affecting the original system. The second step, core processing: Install the "pneumatic triple unit". This is the core device for ensuring the quality of air supply. A separate set must be configured for each new air line. The triple unit includes a filter, a pressure reducing valve, and an oil mist lubricator. The third step is to add a buffer and energy storage unit, namely an air tank. Its function is to provide an instantaneous air source for the cylinder when the main pipeline pressure fluctuates, so as to ensure stable operation. At the same time, it separates some residual moisture. The required volume is calculated according to the cylinder diameter, stroke and operating frequency. A suitable small air tank, such as 30-100 liters, is selected and installed after the triplet and before the cylinder. The fourth step is piping and control: the piping from the branch point to the cylinder should have a sufficient diameter to reduce pressure loss. Usually, the main pipeline is thicker than the branch pipelines to each cylinder. Near the cylinder assembly, a small precision pressure reducing valve can be installed for secondary pressure stabilization to ensure extremely stable pressure. All joints must be reliably sealed with suitable sealing materials.

[0024] In this application, the newly added cylinders do not operate frequently and do not require high response speed. After strict system processing according to the above four steps, they can share the same air source, which is the most economical method. Of course, a separate small air compressor, air tank and separate triple unit can also be configured to supply air to the newly added cylinders. The disadvantage of this is that the initial cost is high, but the advantage is that it is more stable.

[0025] Supplementary explanation of the control system: The control system is connected to the newly added telescopic devices a10, b28, c33, a16, b19 and c30. In addition to these necessary power components, multiple position detection sensors are also installed, such as the position detection of the tilting frame 17, the position detection of the clamping frame 9 and the position detection of the drill rod 7 to be filled. These sensors are all connected to the control system for data transmission.

[0026] In summary, when the drill rod 7 needs to be extended at a designated position during use, the operator does not need to manually loosen the rotary head 5 and the drill rod 7, nor does the operator need to manually pick up the drill rod 7 for manual installation. All of these are completed quickly by the self-disassembly mechanism and the self-filling mechanism. The idle waiting time of the entire equipment is very short, and the safety is also higher. Under the same workload, it can significantly improve work efficiency and energy saving effect of the equipment.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. 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.
