Description

Technical Field

[0001] This application relates to the field of coal mine drilling technology, specifically to a coal mine geological drilling device. Background Technology

[0002] Coal mine geological drilling mainly involves geological exploration, including strata, coal quality, gas content, and aquifers, to lay the foundation for coal mine infrastructure or coal mine working face development, effectively guiding the safe and correct conduct of the work, and guiding and verifying the progress of the project. Unlike traditional drilling, coal mine geological drilling usually requires the preservation of rock cores, which generates more dust during the drilling process. These particles not only obstruct the workers' vision but are also easily inhaled, affecting their health. To reduce dust, dust collection equipment is usually added at the borehole. However, existing dust absorption equipment requires separate installation, which affects the efficiency of drilling work. Summary of the Invention

[0003] Technical problems to be solved To address the aforementioned shortcomings of existing technologies, this application provides a coal mine geological drilling device that effectively solves the problem of generating a large amount of dust particles during drilling, especially in coal mine geology. These particles, dispersed in the air, not only obstruct the workers' vision but are also easily inhaled, affecting their health. While dust collection equipment is typically added at the borehole to collect drilling dust, existing dust absorption equipment requires separate installation, which reduces drilling efficiency.

[0004] Technical solution To achieve the above objectives, this application provides the following technical solution: This application provides a coal mine geological drilling device, including a drive frame, a roller at the bottom of the drive frame for driving the drive frame to move, a drilling track frame on one side of the drive frame, and a drive mechanism for driving the drill rod to rotate and a positioning component for keeping the drill rod moving in a straight line distributed vertically on one side of the drilling track frame. The positioning assembly includes a mounting cylinder fixedly mounted on the drilling track frame, a rotating cylinder for fitting around the outside of the drill pipe is coaxially mounted in the middle of the mounting cylinder, a centrifugal push assembly is provided on the outside of the rotating cylinder, and a dust suction hood is lifted and installed below the mounting cylinder. The centrifugal drive component is used to move the dust collection hood downwards during the rotation of the rotating drum to collect the dust generated during drilling.

[0005] Furthermore, the centrifugal pushing assembly includes a fixed ring fixedly installed inside the mounting cylinder, a lifting ring being installed vertically below the fixed ring, and an elastic element for pulling the lifting ring upwards is provided below the fixed ring. A rotating sleeve is fixedly installed on the outer side of the rotating cylinder, and multiple connecting rods are distributed in a circular array on the outer side of the rotating sleeve. One end of each connecting rod is hinged to the rotating sleeve, and the other end is slidably and rotatably connected to the lower part of the lifting ring. When the multiple connecting rods rotate with the rotating sleeve, they drive the lifting ring to move downwards.

[0006] Furthermore, a linkage rod is fixedly installed below the lifting ring. The lower part of the linkage rod extends out of the mounting cylinder and is fixedly connected to one side of the outer wall of the dust hood. When the lifting ring moves downward, it drives the dust hood to move downward synchronously.

[0007] Furthermore, a rotating connecting ring is rotatably installed below the lifting ring. The inner side of the rotating connecting ring has multiple grooves arranged in a ring array for connecting with the connecting rod. The inner walls on both sides of the grooves are provided with strip holes for rotatably connecting with the connecting rod. Each connecting rod has a counterweight at the end away from the rotating sleeve.

[0008] Furthermore, a guide cylinder is coaxially fixedly installed below the mounting cylinder. The guide cylinder is used to guide the dust collection hood to move up and down. The guide cylinder is provided with a connecting through hole for the linkage rod to extend into. The linkage rod is slidably connected to both sides of the inner wall of the connecting through hole.

[0009] Furthermore, a first partition and a third partition are fixedly installed inside the dust hood. Multiple dust collection frames are fixedly installed on the third partition, and the lower openings of the multiple dust collection frames all face the center of the dust hood. A negative pressure adsorption connection port is fixedly installed on the first partition, and the negative pressure adsorption connection port is connected to the bottom of the first partition. The negative pressure adsorption connection port is used to connect to the external adsorption pipe.

[0010] Furthermore, a second partition is provided between the first partition and the third partition. The second partition has multiple filter holes, and a liquid collection space is formed between the second partition and the third partition. The upper end of the dust collection frame passes through the second partition and extends upward. A drain pipe for discharging liquid is provided below the third partition.

[0011] Furthermore, a water baffle is coaxially fixedly installed above the second partition. The water baffle is funnel-shaped and is used to block the dust collection frame.

[0012] Furthermore, a hydraulic telescopic component is fixedly installed on the drilling track frame. The telescopic end of the hydraulic telescopic component is fixedly connected to the drive mechanism, and the hydraulic telescopic component is used to drive the drive mechanism to move up and down.

[0013] Furthermore, a rotating connecting frame is rotatably mounted on the drive frame, and the drilling track frame is rotatably connected to the drive frame through the rotating connecting frame. A push rod for driving the drilling track frame to rise and fall is provided on the rotating connecting frame.

[0014] Beneficial effects The technical solution provided in this application has the following advantages compared with the known public technology: This application incorporates a centrifugal drive component inside the mounting cylinder. As the rotating cylinder follows the drill rod, it drives the centrifugal drive component to operate, causing the dust collection hood to move downwards and cover the drilled ground. At this time, by activating the external dust collection device, dust generated during drilling can be easily absorbed, preventing the spread of dust and its impact on the health of workers. When the drill rod stops rotating, the centrifugal drive component can easily move the dust collection hood upwards, allowing workers to easily observe the drilling situation when the drill rod stops. This achieves automatic linkage between dust removal and drill rod rotation, solving the problem of traditional equipment requiring independent control and adjustment of the dust removal structure, making the device more integrated and automated.

[0015] In this application, the counterweight, connecting rod, and rotating sleeve have inertia during rotation, forming a wheel-like effect. When the drill pipe encounters a hard coal seam or gets stuck, causing the drill pipe speed to decrease, this wheel-like effect will drive the drill pipe to rotate, giving the drill pipe as a whole greater rotational inertia and reducing the risk of getting stuck.

[0016] This application provides a second partition between the first and third partitions, with multiple filter holes on the second partition. A liquid collection space is formed between the second and third partitions. The upper end of the dust collection frame passes through the second partition and extends upward. After water enters the area above the second partition along the dust collection frame, the water falls onto the second partition and enters the liquid collection space through the filter holes. This not only allows for the unified absorption of water and dust but also filters and discharges the water, reducing the working pressure of the dust collection device. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will be further described below with reference to embodiments.

[0022] Example: A coal mine geological drilling device, such as Figure 1 - Figure 7As shown, the system includes a drive frame 1, with rollers at its bottom that move the drive frame 1. Tracks are fitted around the rollers. A power unit, either an electric motor or an internal combustion engine, is installed inside the drive frame 1 to drive the rollers. Both are common technologies in the prior art. A drilling track frame 2 is mounted on one side of the drive frame 1. A rotating connecting frame 11 is rotatably mounted on the drive frame 1. The drilling track frame 2 is rotatably connected to the drive frame 1 via the rotating connecting frame 11. A push rod is mounted on the rotating connecting frame 11 to move the drilling track frame 2 up and down. By rotating the connecting frame 11 and the push rod, the elevation angle of the drilling track frame 2 can be changed, thereby enabling vertical movement. Drilling operations at different angles, such as straight holes and inclined holes, greatly expand the applicable scenarios of the device. The push rod can be a hydraulic push rod. The drilling track frame 2 is equipped with a drive mechanism 3 for rotating the drill rod and a positioning component for keeping the drill rod moving in a straight line. A hydraulic telescopic component 21 is fixedly installed on the drilling track frame 2. The telescopic end of the hydraulic telescopic component 21 is fixedly connected to the drive mechanism 3. The hydraulic telescopic component 21 is used to drive the drive mechanism 3 to move up and down. Using the hydraulic telescopic component 21 as the propulsion power of the drive mechanism 3 can provide strong and stable drilling pressure, which is convenient for precise control of drilling speed and depth and adapts to rock formations of different hardness. The positioning component includes a mounting cylinder 4 fixedly installed on the drilling track frame 2. A rotating cylinder 41 for fitting around the outside of the drill rod is coaxially rotatably mounted in the middle of the mounting cylinder 4. The rotating cylinder 41 only guides the drill rod to maintain the drilling angle of the drill rod and does not hinder the up and down sliding of the drill rod. A centrifugal pushing component is provided on the outside of the rotating cylinder 41. A dust suction hood 5 is lifted and installed below the mounting cylinder 4. The centrifugal drive component is used to drive the dust collection hood 5 to move downward during the rotation of the rotating drum 41 to collect the dust generated during drilling. The dust collection device can be installed on the drive frame 1. At the same time, the dust collection device is connected to the inside of the dust collection hood 5 through a pipe. The dust collection device can be a powerful dust collection device commonly used in the prior art. Its composition and working principle will not be described in detail here.

[0023] In this application, a centrifugal drive component is installed inside the mounting cylinder 4. When the rotating cylinder 41 rotates with the drill rod, it drives the centrifugal drive component to operate, causing the dust suction hood 5 to move downwards and cover the drilled ground. At this time, by opening the external dust suction device, the dust generated by the drill rod drilling can be absorbed, preventing the dust generated by the drilling from spreading and affecting the health of the workers. When the drill rod stops rotating, the centrifugal drive component stops working, and the dust suction hood 5 can automatically move upwards and reset, making it convenient for workers to observe the drilling situation when the drill rod stops. This realizes the automatic linkage between the dust removal action and the drill rod rotation action, solving the problem that traditional equipment requires independent control and adjustment of the dust removal structure, making the device more integrated and automated.

[0024] Specifically, the centrifugal pushing assembly in this embodiment includes a fixed ring 42 fixedly installed inside the mounting cylinder 4, a lifting ring 43 mounted below the fixed ring 42, and an elastic element 421 below the fixed ring 42 for pulling the lifting ring 43 upward. The elastic element 421 can keep the lifting ring 43 at the top during normal periods (e.g., Figure 5 As shown in the diagram, a rotating sleeve 46 is fixedly installed on the outer side of the rotating cylinder 41. Multiple connecting rods 47 are arranged in a ring array on the outer side of the rotating sleeve 46. One end of each connecting rod 47 is hinged to the rotating sleeve 46, and the other end is slidably and rotatably connected to the lower part of the lifting ring 43. When the multiple connecting rods 47 rotate with the rotating sleeve 46, they drive the lifting ring 43 to move downward. The working process includes: the rotating sleeve 46 rotates → the connecting rod 47 generates centrifugal motion (outward swing) → a downward component force is generated at the connection point between the connecting rod 47 and the lifting ring 43 → overcoming the tension of the elastic element 421, pushing the lifting ring 43 to move downward. Furthermore, a linkage rod 431 is fixedly installed below the lifting ring 43. The lower part of the linkage rod 431 extends out of the mounting cylinder 4 and is fixedly connected to one side of the outer wall of the dust hood 5. The linkage rod 431 is slidably connected to the bottom of the mounting cylinder 4. When the lifting ring 43 moves downward, it drives the dust hood 5 to move downward synchronously. The centrifugal force generated during the rotation of the connecting rod 47 on the outside of the rotating sleeve 46 drives the lifting ring 43 to move downward, which can synchronously drive the dust hood 5 to move downward, so that the dust hood 5 can cover the drilling position, which can collect the dust generated by the drilling in time and prevent the dust from spreading to the surrounding area and affecting the health of the operators.

[0025] In the above embodiment, the lifting ring 43 moves vertically relative to the fixed ring 42, and drives the linkage rod 431 fixedly connected to it to move up and down synchronously. At the same time, the lifting ring 43 also needs to cooperate with the rotating sleeve 46 to rotate synchronously. In view of this, a rotating connecting ring 48 is rotatably installed at the bottom of the lifting ring 43. A protrusion inserted into the inside of the lifting ring 43 is fixedly installed on the rotating connecting ring 48. The protrusion is inserted into the annular groove at the bottom of the lifting ring 43 and is rotatably connected to the groove. The inner side of the rotating connecting ring 48 has a plurality of sliding grooves arranged in an annular array for connecting with the connecting rod 47. The inner walls on both sides of the sliding groove are provided with strip holes 4801 for rotatably connecting with the connecting rod 47. The strip holes 4801 allow one end of the connecting rod 47 to slide toward or away from the center of the rotating connecting ring 48. In the initial state, the connecting rod 47 The rotating connection point with the rotating connecting ring 48 is located near the center of the rotating connecting ring 48. When the rotating sleeve 46 rotates and drives multiple connecting rods 47 to rotate, the end of each connecting rod 47 connected to the rotating connecting ring 48 moves away from the center of the rotating connecting ring 48 as it descends. Each connecting rod 47 is equipped with a counterweight at the end away from the rotating sleeve 46. The counterweight increases the downward thrust generated during the rotation of the connecting rod 47, making it easier to drive the lifting ring 43 downward. In addition, the counterweight, connecting rod 47, and rotating sleeve 46 have inertia during rotation, forming a wheel-like effect. When the drill pipe encounters a hard coal seam or gets stuck, causing the drill pipe speed to decrease, this wheel-like effect will drive the drill pipe to rotate, giving the drill pipe greater rotational inertia and reducing the risk of getting stuck.

[0026] During drilling, the drill rod rotates at high speed, causing the mounting cylinder 4 to vibrate. Similarly, the dust hood 5 located below the mounting cylinder 4 will also vibrate. To prevent the dust hood 5 from swaying below the mounting cylinder 4 during vibration, a guide cylinder 45 is coaxially fixedly installed below the mounting cylinder 4 in this embodiment. A support cylinder 44 is fixedly installed inside the guide cylinder 45. The upper end of the support cylinder 44 extends into the mounting cylinder 4 and is rotatably connected to the bottom of the rotating cylinder 41. The support cylinder 44 separates the interior of the mounting cylinder 4 from the drill rod, preventing dust carried by the drill rod from falling into the interior of the mounting cylinder 4 when it passes through the middle of the mounting cylinder 4. The support cylinder 44 and the guide cylinder 45 are used to guide the dust hood 5 to move up and down more smoothly, making the dust hood 5 slide up and down more stably and reducing the swaying amplitude of the dust hood 5 below the mounting cylinder 4. The guide cylinder 45 is provided with a connecting through hole 4501 for the linkage rod 431 to extend into. The linkage rod 431 is slidably connected to both sides of the inner wall of the connecting through hole 4501.

[0027] Inside the dust hood 5, a first partition 51 and a third partition 53 are fixedly installed. Multiple dust collection frames 531 are fixedly installed on the third partition 53. The lower openings of the multiple dust collection frames 531 all face the center of the dust hood 5, directly opposite the intersection of the drill rod and the drilled ground, which can promptly absorb and discharge the dust generated during drilling. A negative pressure adsorption connection port 511 is fixedly installed on the first partition 51. The negative pressure adsorption connection port 511 is connected to the lower part of the first partition 51 and is connected to an external adsorption pipe. By setting the dust collection device on the drive frame 1, the weight of the dust hood 5 can be reduced, making it easier to move the dust hood 5 up and down.

[0028] Furthermore, in actual coal mine geological drilling, due to the complex geology, thin sandstone aquifers (small, stable, and of poor quality) are frequently encountered. However, the accumulation of this water at the borehole opening can affect the drilling personnel's observation of the borehole location. Although this small amount of water can be quickly absorbed by the dust hood 5, directly sucking it into the dust collection device can easily cause the collected dust to clump together. The mixture of dust and water easily adheres to the inside of the dust collection device's filter box, making subsequent cleaning difficult. Therefore, in this embodiment, a second partition 52 is provided between the first partition 51 and the third partition 53. The second partition 52 is provided with multiple filter holes, and a liquid collection space is formed between the second partition 52 and the third partition 53. 5301, the upper end of the suction frame 531 passes through the second partition 52 and extends upward. A baffle plate 54 is coaxially fixed above the second partition 52. The baffle plate 54 is funnel-shaped and blocks the suction frame 531. After water enters the second partition 52 along the suction frame 531, the water will hit the baffle plate 54 and enter the liquid collection space 5301 through the filter holes. This prevents water droplets from entering the suction device from the negative pressure adsorption connection port 511 and prevents the dust collected inside the suction device from mixing with the water droplets. A drain pipe 532 for draining liquid is provided below the third partition 53. The valve on the drain pipe 532 is opened periodically to drain the wastewater collected inside the liquid collection space 5301. It should be noted that when using the vacuum hood 5 to suck up water, by increasing the airflow rate inside the external adsorption pipe, a lower negative pressure is generated in the space between the first partition 51 and the third partition 53, making the airflow rate inside the vacuum frame 531 faster. In this way, water and air can be sucked up to the top of the second partition 52 simultaneously.

[0029] When drilling is required, the drive frame 1 first moves the entire equipment to the position to be drilled, and the drilling track frame 2 is aligned above the drilling position. Then, the drive mechanism 3 is activated to rotate the drill rod, and at the same time, the hydraulic telescopic component 21 pushes the drive mechanism 3 and the drill rod downward to drill. The rotation of the drill rod causes the rotating cylinder 41 and its rotating sleeve 46 to rotate. Multiple connecting rods 47 fixed on the rotating sleeve 46 rotate accordingly. Under the action of centrifugal force, the counterweight at the end of the connecting rod 47 tends to swing outward, forcing the connecting rod 47 to swing from a near-vertical state to an inclined state. Since the other end of the connecting rod 47 is slidably and rotatably connected to the rotating connecting ring 48 below the lifting ring 43 through the strip hole 4801, the tilting swing of the connecting rod 47 will overcome the tension of the elastic component 421 and push the lifting ring 43 towards... As the drill bit moves downward, the lifting ring 43 drives the dust hood 5 to slide downward along the guide cylinder 45 via the linkage rod 431 until it covers the drilling area. At this time, the dust collection device connected to the external negative pressure adsorption connection port 511 is activated. Dust or water is sucked in from the opening below the dust collection frame 531 at the bottom of the dust hood 5. After being guided by the dust collection frame 531, the water droplets are intercepted in the liquid collection space 5301 under the action of gravity after hitting the baffle plate 54 (which can be periodically discharged by the drain pipe 532). The gas passes through the space between the second partition 52 and the first partition 51 and is discharged from the negative pressure adsorption connection port 511, completing the dust removal or emission of harmful gases. When drilling stops, the rotation speed of the rotating cylinder 41 decreases or stops, the centrifugal force decreases, and under the action of the elastic force of the elastic element 421, the lifting ring 43 is pulled up, driving the dust hood 5 to return to its original position.

[0030] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this application.
