[0019] S10: Move the setting to the appropriate position. If the ground is uneven and the support is tilted, you can start each of the second cylinders at the bottom of the support to control the height of both sides of the support and adjust the support to a horizontal state. Then start the first cylinder to drive the drill rod into the coal seam for drilling.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0038] like Figures 1 to 5As shown, this embodiment proposes a directional drilling device for coal mine gas drainage boreholes, including a support base 1 and a drilling mechanism 2 disposed on the support base 1. It also includes a limiting mechanism, an adjusting mechanism 3 and a moving mechanism. The limiting mechanism includes a guide component 4 disposed on the side wall of the support base 1 to block both sides of the drilling mechanism 2 and a propulsion component 5 disposed at the bottom of the support base 1 to drive the guide component 4 to move horizontally back and forth. The adjusting mechanism 3 is disposed at the bottom of the support base 1 and is used to adjust the horizontal angle of the support base 1. The moving mechanism includes a rolling component 6 disposed at the bottom of the adjusting mechanism 3, a partition 8 disposed on the rolling component 6, a positioning component 7 disposed at the bottom of the partition 8, and a transmission component 9 disposed between the rolling component 6 and the positioning component 7.

[0039] The rolling component 6 moves the equipment to the designated position, then retracts it to lift it off the ground, allowing the main body of the equipment to rest against the ground. During retraction, the rolling component 6 can also drive the positioning component 7 to insert into the soil and fix the equipment in place via the transmission component 9. Then, the support base 1 is adjusted to a horizontal position by the adjustment mechanism 3, and the drilling mechanism 2 can then drill into the coal seam. At the same time, the guide component 4 can block both sides of the drilling mechanism 2. In addition, the propulsion component 5 can drive the guide component 4 to move horizontally back and forth against the outside of the drilling mechanism 2, which facilitates blocking all parts of the drill rod 203, allowing the drilling mechanism 2 to maintain a vertical state when drilling into the coal seam. This avoids the equipment shaking due to vibration during drilling, thus improving the stability of the equipment.

[0040] The drilling mechanism 2 includes a first cylinder 201 disposed on the side wall of the support base 1, a first piston rod 202 disposed at the output end of the first cylinder 201, and a drill rod 203 disposed at the end of the first piston rod 202. When the first cylinder 201 is started, the drill rod 203 is driven to move downward through the first piston rod 202 to drill into the coal seam, and drilling can be carried out.

[0041] It should be noted that the equipment in this application achieves precise control and stable assurance of the drilling trajectory through the coordinated action of the limiting mechanism, the adjusting mechanism, and the moving mechanism. Compared with existing technologies, this equipment has significant improvements in directional accuracy and stability, specifically reflected in the following quantitative parameters:

[0042] Drilling level deviation control: Through the cooperation of the guide component and the propulsion component, the lateral vibration amplitude of the drill rod during drilling can be controlled within ±2 mm, which effectively ensures the levelness of the drill hole and avoids trajectory deviation caused by vibration.

[0043] Equipment positioning stability: Under the action of the transmission mechanism, the positioning component can limit the overall horizontal displacement of the equipment to ≤1 mm, which greatly reduces the shaking of the equipment caused by the reaction force and ensures the continuous stability of the drilling process.

[0044] Support seat horizontal adjustment accuracy: The adjustment mechanism can achieve a horizontal angle deviation of ≤0.5° for the support seat, ensuring that the drill rod is always on the designed drilling axis and improving the directional accuracy of the borehole.

[0045] Drill pipe guidance dynamic response: The propulsion component drives the guide roller to reciprocate along the drill pipe axis at a frequency of 10-20 times / minute, achieving dynamic support and correction of the drill pipe in the entire circumference and effectively suppressing drill pipe sway.

[0046] The implementation of these directional parameters enables the equipment to maintain a high-precision and high-stability drilling state in gas drainage boreholes, significantly improving the quality of borehole formation and extraction efficiency, and solving the problems of unqualified boreholes and poor extraction effects caused by vibration and displacement in traditional equipment.

[0047] Therefore, in practical applications, through the combination of the above-mentioned structure and control methods, this equipment has achieved optimization of the following directional drilling performance parameters, demonstrating significant technical advantages:

[0048] Drilling trajectory deviation rate reduced by ≥60%, and drilling straightness significantly improved;

[0049] The vibration amplitude of the equipment during drilling is reduced by ≥50%, effectively extending the life of the drill bit;

[0050] The drilling positioning repeatability is <5 mm, which is suitable for high-precision gas extraction hole placement requirements.

[0051] The machine's leveling time is less than 3 minutes, which improves on-site construction efficiency.

[0052] Compared with existing technologies, this equipment not only achieves multi-mechanism coordinated stability in structure, but also achieves quantitative improvement in directional control parameters, providing more reliable and efficient drilling equipment support for coal mine gas extraction.

[0053] like Figure 4 , Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the guide component 4 further includes a housing 401 disposed at the bottom of the support base 1, a lead screw 402 rotatably disposed on both sides of the housing 401, a fixed rod 403 disposed on the housing 401, a movable frame 404 threaded on the lead screw 402 and slidably connected to the fixed rod 403, and a roller 405 rotatably disposed on the inner wall of the movable frame 404. The roller 405 contacts the outer wall of the drill rod 203, and a drive component is also disposed inside the housing 401.

[0054] The driving components include a first motor 406 disposed on the outer wall of the housing 401, a driving bevel gear 408 disposed on the output shaft of the first motor 406, and a driven bevel gear 407 disposed on the inner end of the lead screw 402 located in the housing 401.

[0055] When drilling through drill rod 203, the first motor 406 is started to drive the active bevel gear 408 to rotate. The active bevel gear 408 will drive the two lead screws 402, which are equipped with driven bevel gears 407, to rotate. The two lead screws 402 will then drive the two rollers 405 to gradually approach and contact the two sides of drill rod 203 through the two moving frames 404. This can block the two sides of drill rod 203 and prevent drill rod 203 from deviating due to collision and vibration with coal seam during drilling.

[0056] It should be noted that the propulsion component 5 includes a support plate 101 disposed on the side wall of the support base 1, a second motor 501 disposed on the top of the support plate 101, a cam 502 disposed on the output shaft of the second motor 501, a movable rod 503 rotatably disposed at the bottom edge of the cam 502, and a crank rod 504 slidably disposed on the bottom of the support base 1 via a support sleeve 505. One end of the crank rod 504 is rotatably connected to the movable rod 503, and the other end of the crank rod 504 is fixedly connected to the housing 401. During the operation of the drill rod 203, the second motor 501 can be started to drive the cam 502 to rotate. The cam 502 will drive the crank rod 504 to move up and down through the movable rod 503. The crank rod 504 will drive the roller 405 to move horizontally back and forth against the outside of the drill rod 203 through the housing 401, which facilitates obstruction of various parts of the outside of the drill rod 203 and further improves the stability of the drill rod 203 during the drilling process.

[0057] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the adjustment mechanism 3 further includes two symmetrically arranged fixed seats 301, a second cylinder 302 rotatably disposed on the top of the fixed seats 301, and a second piston rod 303 disposed at the output end of the second cylinder 302, the top of the second piston rod 303 being rotatably connected to the bottom of the support seat 1.

[0058] When the equipment is moved to an uneven position, the second cylinders 302 at the four corners of the bottom of the support base 1 can be activated. The second piston rods 303 will lift the four corners of the support base 1. Through their cooperation, the support base 1 can be adjusted to a horizontal state, so that the drill rod 203 can be vertically and stably drilled.

[0059] like Figure 2 , Figure 4 and Figure 8As shown, in a preferred embodiment, based on the above method, the rolling component 6 further includes a third cylinder 601 disposed on the top of the fixed base 301, a third piston rod 602 disposed at the output end of the third cylinder 601 and extending into the interior of the fixed base 301, a sliding plate 603 disposed at the bottom of the third piston rod 602 and slidably connected to the inner wall of the fixed base 301, and a plurality of rollers disposed at the bottom of the sliding plate 603.

[0060] The positioning component 7 includes sliding columns 701 that are slidably disposed on both sides of the top of the partition plate 8, a pressure plate 702 disposed at the bottom of the sliding columns 701, and a number of positioning posts disposed at the bottom of the pressure plate 702.

[0061] The transmission component 9 includes a cover 901 symmetrically arranged on both sides of the top of the partition 8, a rotating rod 902 rotatably arranged on the side wall of the cover 901, a gear 903 arranged on the inner side wall of the rotating rod 902 located on the inner side wall of the cover 901, a first toothed plate 904 arranged on the top of the slide plate 603 and extending through the fixed seat 301 into the interior of the cover 901, and a second toothed plate 905 arranged on the top of the slide column 701.

[0062] When the device needs to be moved, the third cylinder 601 is activated to move the slide plate 603 downward, so that the rollers at the bottom of the slide plate 603 contact the ground, thus moving the device. After the device is moved to the designated position, the third cylinder 601 moves the slide plate 603 upward and retracts it into the fixed base 301. At the same time, when the slide plate 603 moves upward, it also drives the gear 903 to rotate through the first toothed plate 904. The gear 903 also drives the sliding column 701 with the second toothed plate 905 and the pressure plate 702 to move downward, so that the positioning stake at the bottom of the pressure plate 702 penetrates into the soil, thus fixing the main body of the device and further improving the stability of the device.

[0063] The working principle of this invention is as follows: Activating the third cylinder 601 moves the sliding plate 603 downwards, causing the rollers at the bottom of the sliding plate 603 to contact the ground, thus moving the equipment. Once the equipment is moved to the designated position, the third cylinder 601 moves the sliding plate 603 upwards, retracting it into the fixed base 301. Simultaneously, as the sliding plate 603 moves upwards, it also drives the gear 903 to rotate via the first toothed plate 904. The gear 903, in turn, drives the sliding column 701 (equipped with a second toothed plate 905) and the pressure plate 702 downwards, causing the positioning stake at the bottom of the pressure plate 702 to penetrate the soil, thereby fixing the main body of the equipment. Activating the first cylinder 201 causes the drill rod 203 to move downwards through the first piston rod 202, drilling into the coal seam to begin drilling operations. At this time, the first motor 406 is started, driving the active bevel gear 408 to rotate. The active bevel gear 408 drives the two lead screws 402, each equipped with a driven bevel gear 407, to rotate. The two lead screws 402 then drive the two rollers 405, via the two moving frames 404, to gradually approach and contact the sides of the drill rod 203. This blocks the sides of the drill rod 203, preventing it from shifting due to collisions and vibrations with the coal seam during drilling. Additionally, during drilling, the second motor 501 can be started, driving the cam 502 to rotate. The cam 502, via the movable rod 503, drives the crank 504 to move up and down. The crank 504, via the housing 401, drives the rollers 405 to move horizontally back and forth against the outside of the drill rod 203, facilitating obstruction of various parts of the drill rod 203 and further improving its stability during drilling.

[0064] This invention also discloses a method for using a directional drilling device for coal mine gas drainage boreholes, comprising the following steps:

[0065] S10: Move the equipment to a suitable position. If the ground is uneven and the support base 1 tilts, the second cylinders 302 at the bottom of the support base 1 can be started to control the height of both sides of the support base 1 and adjust the support base 1 to a horizontal state. Then start the first cylinder 201 to drive the drill rod 203 to drill into the coal seam for drilling.

[0066] S20: The driving component drives the moving frames 404 on both sides of the drill rod 203 to gradually approach each other, so that the two rollers 405 abut against the two sides of the drill rod 203, blocking the two sides of the drill rod 203 and preventing the drill rod 203 from shifting due to vibration during the drilling process.

[0067] S30: The propulsion component 5 can also drive the rollers 405 that abut against both sides of the drill rod 203 to move horizontally back and forth, blocking various positions on the outside of the drill rod 203;

[0068] S40: The device can be moved by the rolling component 6. When the device is moved to the designated position for operation, the third cylinder 601 can drive the slide plate 603 and rollers to move into the fixed seat 301. At this time, the transmission component 9 can drive the sliding column 701 in the positioning component 7 to move downward, so that the pressure plate 702 and positioning pile at the bottom of the sliding column 701 are inserted into the soil to fix the device.

[0069] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.

At this time, the transmission part (9) drives the sliding column (701) in the positioning part (7) to move downward, so that the pressure plate (702) at the bottom of the sliding column (701) and the positioning pile are inserted into the soil to fix the device.
