Description

Technical Field

[0001] This invention relates to the field of mineral drilling, and more specifically, to a mineral resource exploration drilling apparatus. Background Technology

[0002] A mineral exploration drilling rig (hereinafter referred to as a drilling rig) is a mechanical device specifically used for geological exploration. It drives the drilling tool to drill into the ground to obtain physical geological samples such as rock cores, mineral cores, and rock cuttings in order to explore the distribution, reserves, and quality of underground mineral resources.

[0003] To facilitate the quick and easy installation of drill rods, existing technology (Chinese invention patent application CN120119910A) discloses a mineral resource exploration drilling device that uses a folding alignment mechanism to align the drill rods. While this facilitates installation, the drill rods need to be fixed between the curved top cover and the curved base. However, different drill rods have different sizes, so when the size of the drill rod changes, the existing drilling device's alignment mechanism cannot effectively adapt, only aligning drill rods of a single size, resulting in poor adaptability. Alternatively, multiple sets of curved top covers and curved bases of different sizes are required to accommodate drill rods of different sizes, leading to higher equipment costs. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a mineral resource exploration drilling device.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A mineral resource exploration drilling device includes a drilling machine body, a vertical plate mounted on the drilling machine body, a lifting part and a traction part mounted on the vertical plate, and a lowering part mounted on the vertical plate and connected to the lifting part.

[0009] Furthermore, the drive assembly includes a movable groove 1 opened inside the extension end, a rotating ring 1 rotatably connected in the movable groove 1, multiple guide grooves 1 opened inside the rotating ring 1, and multiple movable parts 1 respectively located in the multiple guide grooves 1 and moving in the guide grooves 1, and the upper and lower ends of the multiple movable parts 1 are rotatably connected to the upper and lower sets of clamping blocks 1 respectively, and the telescopic end of the hydraulic rod 2 is rotatably connected to the rotating ring 1.

[0010] Furthermore, the lower drilling part includes a slide block 1 that slides on the vertical plate and a drive part that is fixed to one side of the vertical plate, and the slide block 1 is connected to the lifting end of the lifting part.

[0011] Furthermore, the height adjustment unit includes a hydraulic rod fixed to the upper end of the slide block one, and two guide rods movably inserted into the interior of the slide block one, wherein the telescopic end of the hydraulic rod one and the lower ends of the two guide rods one are fixed to the upper end of one of the slide blocks two.

[0012] Furthermore, it also includes a coaxial screw connection part connected inside the slide block two and the extension end, and the coaxial screw connection part includes a movable groove two opened inside the extension end, a rotating ring two rotatably connected inside the movable groove two, multiple guide grooves two opened inside the rotating ring two, multiple movable parts two respectively located inside the multiple guide grooves two, multiple clamping blocks two respectively rotatably connected to the upper and lower ends of the multiple movable parts two, multiple rotating wheels respectively rotatably connected to one end of the multiple clamping blocks two, and a hydraulic rod three rotatably connected inside the slide block two and whose telescopic end is rotatably connected to the rotating ring two. The multiple clamping blocks two are all movably inserted into the interior of the extension end, and one end of the multiple clamping blocks two extends into the groove.

[0013] Furthermore, it also includes a self-aligning and anti-deviation treatment component connected inside the extension end, and the self-aligning and anti-deviation treatment component includes a transmission part connected inside the extension end for driving the drill rod in the trench to rotate, and a surface treatment part connected inside the extension end for cleaning the outer surface of the drill rod in the trench.

[0014] Furthermore, the transmission unit includes a movable groove three that is opened inside the extension end and communicates with the groove body, a movable seat that slides in the movable groove three, a hydraulic rod six that is fixed inside the extension end and whose telescopic end is fixed to the movable seat, a drive wheel that is rotatably connected inside the movable seat, and a motor that is fixed to one side of the movable seat and connected to the drive wheel and drives the drive wheel to rotate.

[0015] Furthermore, the surface treatment unit includes two guide rods 2 that are movably inserted into the extension end, a frame fixed to one end of the two guide rods 2, a grinding component fixed to one side of the frame and located in the groove, and a hydraulic rod 4 fixed to the extension end and whose telescopic end is fixed to one side of the frame.

[0016] Furthermore, one of the slide blocks is connected to a lower end of a drilling anti-deviation treatment unit, which includes a fixed seat and a hydraulic rod five fixed to the lower end of the slide block two, two guide rods three movably inserted into the fixed seat, a seat body fixed to one end of the two guide rods three, a scraper fixed to one side of the seat body, a discharge port opened on one side of the seat body, and a feed connector opened on one side of the seat body and connected to the discharge port. The telescopic end of the hydraulic rod five is fixed to one side of the seat body.

[0017] Furthermore, a drill rod clamp is connected to the lower end of the vertical plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) This solution is equipped with a coaxial positioning component. The coaxial positioning component can quickly center and clamp drill rods of different sizes, and the device has better adaptability. The drill rod is mechanically limited to the correct center position when it is in place, reducing coaxial error. When the upper end of the drill rod is connected to the drive unit, there is almost no lateral force, completing the static connection at the upper end and improving the overall axial stability of the drill string after connection. Each drill rod maintains a certain coaxiality when it is installed, and the cumulative bending error of the entire drill string will be greatly reduced.

[0020] (2) This solution is equipped with a coaxial screw joint. Multiple rotating wheels can form an automatic constraint of the geometric center. When the drill rod is driven to rotate, the contact surface of the rotating wheels can dynamically correct the eccentricity of the drill rod and prevent it from jumping during rotation. It can make the lower end of the drill rod accurately aligned with the drill tool below (or the drill rod already in the hole in the formation) and complete the dynamic screwing of the lower end, avoiding the deviation or jamming during thread engagement. The uniform force of the rotating wheels can also prevent the drill rod from swinging or shaking and maintain a stable posture. It ensures the high coaxiality of the entire drill rod string from beginning to end and greatly protects the threads and drive equipment.

[0021] (3) This solution is equipped with a self-aligning and anti-deviation treatment component. The drive wheel drives the drill rod to rotate, and the grinding component is used to rough grind the outer surface of the drill rod to remove impurities. After cleaning, the drill rod surface can directly contact the clamping block and the rotating wheel. The clamping force is transmitted accurately and directly. The centering clamping is not affected by the thickness of impurities. The center line alignment effect is good. The drill rod is forcibly fixed on the designed geometric center, eliminating the misalignment and deviation caused by the uneven medium on the drill rod surface. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 9 A mineral resource exploration drilling device includes a drilling machine body 1, a vertical plate 2 mounted on the drilling machine body 1, a lifting part 3 and a traction part 4 mounted on the vertical plate 2, and a lower drilling part 5 mounted on the vertical plate 2 and connected to the lifting part 3. The lower end of the vertical plate 2 is connected to a drill pipe slip 10, which is a special tool used in drilling operations to clamp and suspend the drill pipe string at the wellhead. Its core function is clamping and suspending. When it is necessary to install or remove the drill pipe, the slip is placed into the filling center of the drilling platform. Its wedge-shaped structure and teeth can firmly bite the drill pipe, thereby suspending the drill pipe string, which is hundreds to thousands of meters long, at the wellhead and preventing it from falling into the well. This is a mature existing technology and will not be described in detail here.

[0035] It also includes two coaxial positioning components 6 connected to one side of the upright plate 2. The coaxial positioning component 6 includes a slide block 61 that slides to one side of the upright plate 2, an extension end 63 integrally formed on one side of the slide block 61, a groove 64 opened inside the extension end 63, a coaxial centering part 65 connected inside the extension end 63, and a height adjustment part 62 connected to the lower drilling part 5 and used to drive one of the slide blocks 61 to rise and fall.

[0036] The coaxial positioning assembly 6 includes two sets of clamping blocks 655 movably connected inside the extension end 63, a drive assembly rotatably connected inside the extension end 63 for moving the two sets of clamping blocks 655 within the extension end 63, and a hydraulic rod 656 rotatably connected inside the slide block 61 with its telescopic end connected to the drive assembly. One end of each of the clamping blocks 655 extends into the groove 64.

[0037] The drive assembly includes a movable groove 651 formed inside the extension end 63, a rotating ring 652 rotatably connected in the movable groove 651, a plurality of guide grooves 653 formed inside the rotating ring 652, and a plurality of movable parts 654 respectively located in the plurality of guide grooves 653 and moving in the guide grooves 653. The upper and lower ends of the plurality of movable parts 654 are rotatably connected to the upper and lower sets of clamping blocks 655 respectively. The telescopic end of the hydraulic rod 656 is rotatably connected to the rotating ring 652.

[0038] The lower drilling part 5 includes a slide block 51 that slides on the vertical plate 2 and a drive part 52 that is fixed to one side of the vertical plate 2, and the slide block 51 is connected to the lifting end of the lifting part 3.

[0039] The height adjustment unit 62 includes a hydraulic rod 621 fixedly connected to the upper end of the slide 51, and two guide rods 622 movably inserted into the slide 51. The telescopic end of the hydraulic rod 621 and the lower ends of the two guide rods 622 are fixedly connected to the upper end of one of the slides 61.

[0040] By adopting the above technical solution, the entire drill string is first lifted out of the ground. The exposed part of the drill string is clamped by the drill string slip 10. The drive unit 52 is controlled to rotate and separate from the upper end of the drill string. Then, the lifting unit 3 is controlled to drive the lower drill unit 5 and the upper slide block 61 to move upward. The drill rod to be installed is lifted by the traction rope and put into the groove 64 of the two slide blocks 61. The hydraulic rod 656 in the two slide blocks 61 is controlled to extend. The extension of the hydraulic rod 656 drives the rotating ring 652 to rotate in the movable groove 651. When the rotating ring 652 rotates, the movable part 654 moves along the guide groove 653. The movement of the movable part 654 drives the two sets of clamping blocks 655 to move, so that one end of the two sets of clamping blocks 655 can be in contact with the drill rod surface in the groove 64. The drill rod is clamped by the clamping blocks 655 inside the two slide blocks 61. Then, the hydraulic rod 621 is controlled to retract, which drives the upper slide block 61 to move. The upper slide block 61 moves the drill rod and the lower slide block 61 upward. The drive unit 52 rotates to screw into the upper end of the drill rod. The coaxial positioning component 6 can quickly center and clamp drill rods of different sizes, making the device more adaptable. The drill rod is mechanically positioned in the correct center position when it is lifted, reducing coaxial error. When the upper end of the drill rod is engaged with the drive unit 52, there is almost no lateral force, completing the static connection at the upper end. This improves the overall axial stability of the drill string after connection. Each drill rod maintains a certain degree of coaxiality during installation, and the cumulative bending error of the entire drill string is greatly reduced.

[0041] like Figure 3 and Figure 6 As shown, it also includes a coaxial screw connection 7 connected inside the slide block 61 and the extension end 63. The coaxial screw connection 7 includes a movable groove 71 opened inside the extension end 63, a rotating ring 72 rotatably connected inside the movable groove 71, a plurality of guide grooves 73 opened inside the rotating ring 72, a plurality of movable parts 74 respectively located inside the plurality of guide grooves 73, a plurality of clamping blocks 75 respectively rotatably connected to the upper and lower ends of the plurality of movable parts 74, a plurality of rotating wheels 76 respectively rotatably connected to one end of the plurality of clamping blocks 75, and a hydraulic rod 77 rotatably connected inside the slide block 61 and whose telescopic end is rotatably connected to the rotating ring 72. The plurality of clamping blocks 75 are all movably inserted into the interior of the extension end 63, and one end of the plurality of clamping blocks 75 extends into the groove 64.

[0042] By adopting the above technical solution, after the upper end of the drill rod engages with the drive unit 52, the hydraulic rod 77 in the two slide blocks 61 is extended. The extension of the hydraulic rod 77 drives the rotating ring 72 to rotate in the movable groove 71. When the rotating ring 72 rotates, the movable part 74 moves along the guide groove 73. The movement of the movable part 74 drives the clamping block 75 to move, so that one end of the multiple clamping blocks 75 moves toward the drill rod in the groove 64, and the rotating wheel 76 at one end of the multiple clamping blocks 75 contacts the outer surface of the drill rod. Then, the hydraulic rod 656 is retracted and drives the rotating ring 652 to rotate, so that the multiple clamping blocks 655 release the clamping of the drill rod. The lifting unit 3 drives the lower drilling unit 5, the drill rod connected to the drive unit 52, and the two coaxial positioning components 6 that center the drill rod to descend synchronously, so that... The lower end of the drill pipe contacts the upper end of the drill string held by the drill pipe slip 10. The control drive unit 52 drives the drill pipe to rotate, so that the lower end of the drill pipe is screwed into the upper end of the drill string. When the drive unit 52 drives the drill pipe to rotate, multiple rotating wheels 76 that are in contact with the outer surface of the drill pipe will rotate accordingly. The multiple rotating wheels 76 can form an automatic constraint of the geometric center. When the drill pipe is driven to rotate by the drive unit 52, the contact surface of the rotating wheels 76 can dynamically correct the eccentricity of the drill pipe and prevent it from jumping during rotation. It can make the lower end of the drill pipe precisely aligned with the lower drill string, complete the dynamic screwing of the lower end, and avoid the deviation or jamming during thread engagement. The uniform force of the rotating wheels 76 can also prevent the drill pipe from swinging or shaking and maintain a stable posture. It ensures the high coaxiality of the entire drill string from beginning to end and greatly protects the threads and drive equipment.

[0043] like Figures 4-7 As shown, it also includes a self-aligning and anti-deviation treatment component 8 connected inside the extension end 63, and the self-aligning and anti-deviation treatment component 8 includes a transmission part 81 connected inside the extension end 63 for driving the drill rod in the groove 64 to rotate, and a surface treatment part 82 connected inside the extension end 63 for cleaning the outer surface of the drill rod in the groove 64.

[0044] The transmission unit 81 includes a movable groove 811 that is opened inside the extension end 63 and communicates with the groove 64, a movable seat 813 that is slidably connected in the movable groove 811, a hydraulic rod 812 that is fixed inside the extension end 63 and whose telescopic end is fixed to the movable seat 813, a drive wheel 815 that is rotatably connected inside the movable seat 813, and a motor 814 that is fixed to one side of the movable seat 813 and connected to the drive wheel 815 and drives the drive wheel 815 to rotate.

[0045] The surface treatment unit 82 includes two guide rods 823 that are movably inserted into the extension end 63, a frame 822 fixed to one end of the two guide rods 823, a grinding component 824 fixed to one side of the frame 822 and located in the groove 64, and a hydraulic rod 821 fixed to the extension end 63 and whose telescopic end is fixed to one side of the frame 822.

[0046] By adopting the above technical solution, the drill rod to be installed is hoisted with a traction rope, allowing it to enter the groove 64 of the two slide blocks 2 61. Then, the hydraulic rod 3 77 in the two slide blocks 2 61 is extended. The extension of the hydraulic rod 3 77 drives the rotating ring 2 72 to rotate in the movable groove 2 71. When the rotating ring 2 72 rotates, the movable part 2 74 moves along the guide groove 2 73. The movement of the movable part 2 74 drives the clamping blocks 2 75 to move, causing one end of the multiple clamping blocks 2 75 to move towards the drill rod in the groove 64, so that the rotating wheel 76 at one end of the multiple clamping blocks 2 75 contacts the outer surface of the drill rod. The hydraulic rod 6 812 is then controlled to extend the movable seat 813 from the movable groove 3 811, causing the drive wheel 815 in the movable seat 813 to contact the drill rod. The outer surface contacts the drill rod. The hydraulic rod 821 controls the movement of the frame 822, allowing the grinding part 824 on one side of the frame 822 to contact the outer surface of the drill rod. The motor 814 controls the drive wheel 815 to rotate, which in turn rotates the drill rod. At the same time, the grinding part 824 performs rough grinding on the outer surface of the drill rod, removing impurities. After cleaning, the drill rod is clamped by the clamping block 655. The cleaned drill rod surface can directly contact the clamping block 655 and the rotating wheel 76. The clamping force is transmitted accurately and directly. The centering clamping is not affected by the thickness of impurities, and the center line alignment is better. The drill rod is forcibly fixed on the designed geometric center, eliminating the misalignment and deviation caused by uneven medium on the drill rod surface.

[0047] like Figure 3 and Figure 9 As shown, one of the slide blocks 2 61 is connected to a lower end of a down-drill anti-deviation treatment part 9, and the down-drill anti-deviation treatment part 9 includes a fixed seat 91 and a hydraulic rod 5 92 fixed to the lower end of the slide block 2 61, two guide rods 3 93 movably inserted into the fixed seat 91, a seat body 94 fixed to one end of the two guide rods 3 93, a scraper 95 fixed to one side of the seat body 94, a discharge port 97 opened on one side of the seat body 94, and a feed connector 96 opened on one side of the seat body 94 and connected to the discharge port 97. The telescopic end of the hydraulic rod 5 92 is fixed to one side of the seat body 94.

[0048] By adopting the above technical solution, the extension of the hydraulic rod 92 can drive the seat 94 to move towards the outer surface of the drill rod, so that the scraper 95 can contact the threaded end of the drill rod or the outer surface of the drill rod. The feed joint 96 is connected to a lubricating fluid supply pipe. After the lubricating fluid enters the feed joint 96, it is discharged from the discharge port 97. The lubricating fluid discharged from the discharge port 97 can reach the threaded end of the drill rod or the outer surface of the drill rod. The scraper 95 scrapes the lubricating fluid and applies it to the threaded end of the drill rod or the outer surface of the drill rod. After lubrication, the friction coefficient is stable and the meshing is uniform when the lower end of the drill rod is screwed, preventing the jamming problem caused by dry meshing and ensuring that the two drill rods achieve precise coaxial connection. When the lubricating fluid is applied to the outer surface of the drill rod, the jamming between the outer surface of the drill rod and the guide device is reduced. When the winch is lowered, the drill rod posture is smoother and the axis is more stable. It can also reduce the wear caused by repeated friction of small eccentric forces.

[0049] Instructions for use: First, lift the entire drill string to the surface. Clamp the exposed portion of the drill string using the drill string slips 10. Control the drive unit 52 to rotate and separate it from the upper end of the drill string. Then, control the lifting unit 3 to move the lower drill unit 5 and the upper slide block 61 upwards. Lift the drill rod to be installed using a traction rope, allowing it to enter the groove 64 of the two slide blocks 61. Subsequently, control the hydraulic rod 77 in the two slide blocks 61 to extend. The extension of the hydraulic rod 77 causes the rotating ring 72 to rotate in the movable groove 71. As the rotating ring 72 rotates, the movable part 74 moves along the guide groove 73. The hydraulic cylinder 812 moves the clamping blocks 75, causing one end of each clamping block 75 to move towards the drill rod in the groove 64, bringing the rotating wheels 76 at one end of each clamping block 75 into contact with the outer surface of the drill rod. The hydraulic cylinder 812 then moves the movable seat 813 out of the movable groove 811, bringing the drive wheel 815 inside the movable seat 813 into contact with the outer surface of the drill rod. The hydraulic cylinder 821 then moves the frame 822, allowing the grinding element 824 on one side of the frame 822 to contact the outer surface of the drill rod. The motor 814 then rotates the drive wheel 815, causing the drill rod to rotate, while the grinding element 824 performs rough grinding on the outer surface of the drill rod. The process involves cleaning impurities from the outer surface of the drill rod; after cleaning, the drill rod is clamped by clamping block 655, and then hydraulic rod 621 is controlled to retract. Hydraulic rod 621 drives the upper slide block 61 to move, which in turn moves the drill rod and the lower slide block 61 upwards. The drive unit 52 rotates to engage with the upper end of the drill rod. After the upper end of the drill rod engages with the drive unit 52, hydraulic rod 77 in the two slide blocks 61 is extended. The extension of hydraulic rod 77 drives rotating ring 72 to rotate in movable groove 71. When rotating ring 72 rotates, movable part 74 moves along guide groove 73. The movement of movable part 2 74 drives the movement of clamping block 2 75, causing one end of multiple clamping blocks 2 75 to move toward the drill rod in the groove 64, so that the rotating wheel 76 at one end of multiple clamping blocks 2 75 contacts the outer surface of the drill rod; then the hydraulic rod 2 656 is controlled to retract and drive the rotating ring 1 652 to rotate, so that multiple clamping blocks 1 655 release the clamping of the drill rod; the lifting part 3 is controlled to drive the lower drilling part 5, the drill rod connected to the drive part 52, and the two coaxial positioning components 6 for centering the drill rod to descend synchronously, so that the lower end joint of the drill rod contacts the upper end joint of the drill rod column held by the drill rod slip 10; the drive part 52 is controlled to drive the drill rod to rotate, so that the lower end of the drill rod is screwed to the upper end of the drill rod column.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
