Abstract
Description
Technical Field
[0001] This invention relates to the field of coal mine tunneling technology, specifically to a rapid tunneling drilling device for deep well close-range coal seam mining. Background Technology
[0002] Deep-well close-range coal seams refer to coal seams that are mined at very deep depths and have very close spacing between them. Generally, when the spacing between the layers is less than 10-15 times the mining height of the thinner coal seam, it can be considered a close-range coal seam. When the spacing between the layers is less than 10 to 15 meters (especially for medium-thick and thinner coal seams), the mining of the upper and lower coal seams will produce significant mutual disturbance.
[0003] In deep, close-range coal seam mining, drilling equipment is needed to determine the gas content and pressure of the coal seam, release gas in advance or take extraction measures to avoid coal and gas outburst accidents, and play an early warning role. At the same time, drilling equipment is also needed to obtain coal seam thickness, fracture development and surrounding rock mechanical parameters to provide a basis for roadway location selection, or to carry out support drilling while tunneling.
[0004] When conducting rapid tunneling in deep mines near coal seams, in order to improve the tunneling speed and maintain good safety, the drilling process must not only efficiently break through rock and coal seams, but also adapt to harsh conditions such as high ground pressure, high gas levels, and fractured surrounding rock. Rapid tunneling in deep mines near coal seams generates a large amount of slag. A large amount of slag will accumulate at the drilling site, which will not only obstruct the passage of equipment, but also cause dust to be re-entrained when cleaning the slag. In addition, the coal dust in the dust is flammable and explosive. Excessive accumulation of coal dust in the tunnel may cause an explosion when it comes into contact with an open flame, posing a huge threat to the entire mine. Summary of the Invention

[0050] The working principle and beneficial effects of this invention are as follows:
[0051] 1. In this invention, during the drilling process, the soil discharge frame is driven to rotate. As the soil discharge frame rotates, it sends the excavated soil generated during the drilling process into the soil discharge trough through the soil collection plate, and discharges it through the soil discharge trough. The excavated soil discharged inside the soil discharge frame will accumulate on the outside of the soil discharge frame. At the same time, the discharged excavated soil is pushed away by the agitator plate, thereby preventing the excavated soil inside the soil discharge frame from accumulating on the outside of the soil discharge frame and affecting the discharge of excavated soil. This not only reduces the problem of equipment passage obstruction, but also facilitates the stable operation of drilling.
[0052] 2. In this invention, during the drilling process, the guide frame rotates around the axis of the soil discharge frame as the soil discharge frame rotates. At this time, the first gear of the first gear ring rotates, thereby assisting the discharge of excavated soil through the continuous rotation of the guide frame, thereby reducing the occurrence of soil blockage in the soil discharge trough and ensuring that the soil discharges smoothly and does not block the soil discharge trough.
[0053] 3. In this invention, as the soil removal frame rotates, dust is generated during the process of sending the excavated soil produced during drilling into the soil removal trough through the soil collection plate. Since the coal dust mixed in the dust is flammable and explosive, excessive accumulation of coal dust in the roadway may cause an explosion when it comes into contact with an open flame, posing a huge threat to the entire mine. At this time, the joint is connected to the water source in advance, and then the water spray head is turned on. Water enters the water spray pipe through the connecting pipe and is sprayed out in the form of water mist through the setting of the water spray head, thereby suppressing dust and improving the safety of drilling operations.
[0054] 4. In this invention, by setting up the slag discharge component, the drilled slag is continuously removed during the drilling operation, which not only facilitates the continuous drilling operation, but also reduces the possibility of equipment passage being obstructed due to slag accumulation. By setting up the dust treatment component, not only can dust be adsorbed and treated during the drilling process, but secondary dust can also be suppressed during the removal of slag, thereby improving the safety of the operation.

Detailed Implementation
[0067] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0068] like Figures 1 to 10As shown in the figure, this embodiment proposes a rapid tunneling drilling device for deep well near-distance coal seam mining, including a device frame 1, a sliding frame 2 slidably installed inside the device frame 1, and a drill rod 3 rotatably installed on the sliding frame 2. It also includes a first motor 4, a drive assembly, a mounting cylinder 5, a cavity 6, a slag discharge assembly, and a dust treatment assembly. The first motor 4 is fixedly installed on the sliding frame 2, and its output end is coaxially and fixedly connected to the mounting end of the drill rod 3. The drive assembly is installed on the device frame 1 and is used to control the movement of the sliding frame 2. The drive assembly includes a third motor. 34. Lead screw 35 and telescopic protective sleeve 37. The third motor 34 is fixedly installed on the device frame 1. The lead screw 35 is rotatably installed inside the device frame 1. One end of the lead screw 35 is fixedly connected to the output end of the third motor 34. A nut 36 is threaded on the lead screw 35. The nut 36 is fixedly connected to the sliding frame 2. A telescopic protective sleeve 37 is fixedly installed between the top surface of the sliding frame 2 and the inner top wall of the device frame 1. A telescopic protective sleeve 37 is also fixedly installed between the bottom surface of the sliding frame 2 and the inner bottom wall of the device frame 1. The lead screw 35 is located inside the two telescopic protective sleeves 37.
[0069] Specifically, when drilling is required, the device frame 1 is first moved to the drilling position, and then the first motor 4 is turned on. The first motor 4 drives the drill rod 3 to rotate. At this time, the third motor 34 is turned on, and the third motor 34 drives the lead screw 35 to rotate, thereby driving the nut 36 to move along the axis of the lead screw 35. The telescopic protective sleeve 37 plays a role in protecting the lead screw 35. At this time, the sliding frame 2 moves along the axis of the lead screw 35 under the action of the nut 36. Thus, drilling operations are carried out through the setting of the drill rod 3.
[0070] During drilling, a large amount of excavated soil and dust will be generated. At this time, the excavated soil discharge component is activated. First, the bottom of the excavated soil discharge component is brought into contact with the ground at the drilling location. The dust and excavated soil will first enter the inside of the excavated soil discharge component, and then be discharged through the setting of the excavated soil discharge component. This prevents the excavated soil from accumulating at the drilling location and affecting the drilling process. It can also prevent the equipment from being difficult to pass due to the accumulation of excavated soil. At the same time, the dust treatment component is activated to treat the dust generated during the drilling process and the excavated soil discharge process.
[0071] like Figures 5 to 9As shown, the mounting cylinder 5 is fixedly installed on the device frame 1. The mounting cylinder 5 is coaxially arranged with the drill rod 3 and is located at the lower part of the sliding frame 2. The mounting cylinder 5 has a cavity 6 inside, and a conical cylinder 7 is coaxially fixedly installed inside the cavity 6. The conical cylinder 7 divides the cavity 6 into a dust removal chamber and a drive chamber. The slag discharge assembly is installed at the bottom of the mounting cylinder 5 and is used to discharge the slag generated during drilling. The slag discharge assembly includes a placement trough 8, a slag discharge frame 9, a slag discharge trough 10, a support part, a slag discharge part, and a drive part. The mounting cylinder 5 has a placement trough 8 at the bottom, and the slag discharge frame 9 is slidably installed in the placement trough 8. Several slag discharge troughs 10 are opened at equal angles in a circular shape on the slag discharge frame 9. A support part is installed at the bottom of the slag discharge frame 9 to support the slag discharge frame 9. Each of the several slag discharge troughs 10 has a slag discharge part installed inside to discharge the slag generated during drilling. A drive part is installed on the mounting cylinder 5 to drive the slag discharge frame 9 to rotate.
[0072] Specifically, when it is necessary to handle the excavated soil generated during drilling, the drive unit first pushes the soil removal frame 9 to the working position, at which point the support unit contacts the ground, and drilling operations can begin. As drilling progresses, a large amount of excavated soil enters the inside of the soil removal frame 9. At this time, the drive unit drives the soil removal frame 9 to rotate within the placement groove 8. The soil removal frame 9 rotates relative to the support unit, thereby discharging the excavated soil that has entered the soil removal frame 9 through the soil removal unit, thus ensuring the normal progress of drilling.
[0073] The above, such as Figure 2 , Figure 7 , Figure 8 As shown, the support part includes a support ring 11 and positioning pins 13. The support ring 11 is coaxially and rotatably installed at the bottom of the soil dumping frame 9. An annular groove 12 is opened inside the support ring 11. Several positioning pins 13 are fixedly installed at equal angles in a circular shape at the bottom of the support ring 11.
[0074] Specifically, during the process of pushing the soil dumping frame 9 to the working position, the soil dumping frame 9 pushes the support ring 11 to move until the support ring 11 contacts the ground, thus fixing the position of the soil dumping frame 9. At this time, the support ring 11 is fixed to the ground by the setting of the positioning pin 13, thereby ensuring that the support ring 11 provides stable support for the soil dumping frame 9, and ensuring the stability of the support ring 11 when the soil dumping frame 9 and the support ring 11 rotate relative to each other.
[0075] The above, such as Figure 7 , Figure 8As shown, the soil discharge section includes a soil-gathering plate 14, a guide frame 15, a first toothed ring 17, and a deflecting plate 18. A soil-gathering plate 14 is fixedly installed inside each soil discharge trough 10, and the free end of the soil-gathering plate 14 is located inside the soil discharge frame 9. A guide frame 15 is rotatably installed inside each soil discharge trough 10. A first gear 16 is fixedly installed at the bottom of each guide frame 15. The first gear 16 is located inside the annular groove 12. The first toothed ring 17 is coaxially fixedly installed inside the annular groove 12. Each first gear 16 meshes with the first toothed ring 17. Several deflecting plates 18 are fixedly installed at equal angles in a circular shape on the outside of the soil discharge frame 9. The several deflecting plates 18 are staggered from the several soil discharge troughs 10.
[0076] Specifically, during the drilling process, to remove the excavated soil that has entered the soil removal frame 9, the soil removal frame 9 is driven to rotate in the following direction: Figure 7 As indicated by the arrow in direction B, with the rotation of the soil discharge frame 9, the soil discharge frame 9, through the soil collection plate 14, sends the excavated soil generated during drilling into the soil discharge trough 10, and discharges it through the soil discharge trough 10. The excavated soil discharged from the inside of the soil discharge frame 9 will accumulate on the outside of the soil discharge frame 9. At this time, the excavated soil is pushed away by the actuating plate 18, thereby preventing the excavated soil discharged from the inside of the soil discharge frame 9 from accumulating on the outside of the soil discharge frame 9, thus affecting the discharge of excavated soil.
[0077] As the soil discharge frame 9 rotates, the excavated soil generated during drilling is fed into the soil discharge trough 10 through the soil collection plate 14. At this time, the guide frame 15 rotates around the axis of the soil discharge frame 9. The first gear 16 of the first gear ring 17 rotates, thereby assisting the excavated soil to be discharged through the guide frame 15, reducing the occurrence of excavated soil clogging in the soil discharge trough 10, and ensuring smooth discharge of excavated soil.
[0078] The above, such as Figure 5 , Figure 6 As shown, the drive unit includes a drive component 19, a push ring 20, and a second motor 22. Several drive components 19 are fixedly installed in a circumferential shape at equal angles in the drive chamber. The drive components 19 are preferably in the form of electric cylinders. The push ring 20 is slidably installed inside the placement groove 8. A second toothed ring 21 is rotatably installed at the bottom of the push ring 20. The second toothed ring 21 is fixedly connected to the soil discharge frame 9. The second motor 22 is fixedly installed on the mounting cylinder 5. A second gear 23 is fixedly installed at the output end of the second motor 22. The second gear 23 meshes with the second toothed ring 21.
[0079] Specifically, when the soil-discharging frame 9 is moved within the placement slot 8, the drive unit 19 is activated. The drive unit 19 pushes the push ring 20 to move, and the push ring 20 pushes the second gear ring 21 to move. The second gear ring 21 and the second gear 23 slide relative to each other until the second gear 23 pushes the soil-discharging frame 9 to the working position. Then, the drive unit is closed and locked. During drilling, the second motor 22 is activated. The second motor 22 drives the second gear 23 to rotate, and the second gear 23 drives the second gear ring 21 to rotate. At this time, the second gear ring 21 can drive the soil-discharging frame 9 to rotate. At the same time, the second gear ring 21 and the push ring 20 rotate relative to each other until the drilling operation is completed. Then, the second motor 22 is closed and the drive unit 19 is retracted.
[0080] like Figures 2 to 4 as well as Figure 10 As shown, a dust treatment assembly is installed inside the mounting cylinder 5 to collect and treat the dust generated during drilling. The dust treatment assembly includes a dust suction trough 24, a dust suction hood 25, a through groove 26, a dust removal section, and a water spray section. Several dust suction troughs 24 are circumferentially formed on the inner side of the mounting cylinder 5. The dust suction troughs 24 are connected to the dust removal chamber. The dust suction hood 25 is fixedly installed on the top of the mounting cylinder 5. A through groove 26 is formed on the top of the mounting cylinder 5. The dust suction hood 25 is connected to the dust removal chamber through the through groove 26. The dust removal section is fixedly installed on the device frame 1 to treat the dust generated during drilling. The water spray section is installed on the mounting cylinder 5 for spraying water.
[0081] Specifically, as drilling operations proceed, dust is continuously generated. At this time, the dust removal unit is activated, and the air in the dust suction trough 24 is extracted through the dust removal unit. The dust is connected to the dust removal chamber through the through groove 26, so that the dust generated during drilling is sucked into the dust removal chamber through the dust suction trough 24, and then enters the dust removal unit through the through groove 26 and the dust suction hood 25 in sequence for dust treatment.
[0082] As the soil discharge frame 9 rotates, dust will also be generated during the process of sending the excavated soil generated during drilling into the soil discharge trough 10 through the soil collection plate 14. At this time, the water spray unit is turned on. The water spray unit is connected to the water source in advance, so that water is sprayed when the excavated soil is discharged from the soil discharge trough 10, which plays a role in suppressing dust.
[0083] The above, such as Figure 3 , Figure 10 As shown, the dust removal unit includes a dust collector 27, a dust removal pipeline 28, and a fan 29. The dust collector 27 is fixedly installed on the device frame 1. The dust removal pipeline 28 connects the input end of the dust collector 27 and the dust collection hood 25. The fan 29 is fixedly installed on the dust collector 27, and the inlet and outlet ends of the fan 29 are connected to the output end of the dust collector 27.
[0084] Specifically, when dealing with the generated dust, the fan 29 needs to be turned on. The fan 29 draws air from the dust collector 27, and then draws air from the dust collection trough 24 through the dust collection pipe 28 until the dust generated during drilling is drawn into the dust collection chamber through the dust collection trough 24. The dust then passes through the through groove 26, the dust collection hood 25, and the dust collection pipe 28 in sequence until it enters the dust collector 27. The dust is then treated by the dust collector 27.
[0085] The above, such as Figure 2 , Figure 4 As shown, the water spraying unit includes a water spray pipe 30 and a connecting pipe 32. The water spray pipe 30 is fixedly installed outside the mounting cylinder 5. The water spray pipe 30 is located at the bottom of the device frame 1. Several water spray heads 31 are connected at equal intervals on the water spray pipe 30. The connecting pipe 32 is installed on the device frame 1. One end of the connecting pipe 32 is connected to the water spray pipe 30, and the other end of the connecting pipe 32 is connected to a connector 33.
[0086] Specifically, during the process of sending the excavated soil generated during drilling into the discharge trough 10, the water source is connected to the connector 33. At this time, the water spray head 31 is turned on, and water enters the water spray pipe 30 through the connecting pipe 32 and is sprayed out in the form of water mist through the setting of the water spray head 31, thereby suppressing dust.
[0087] The working principle or usage process of this application is as follows:
[0088] When drilling is required, the device frame 1 is first moved to the drilling position. At this time, the drive component 19 is turned on, and the drive component 19 pushes the push ring 20 to move. The push ring 20 pushes the second toothed ring 21 to move. The second toothed ring 21 and the second gear 23 slide relative to each other. The second gear 23 pushes the soil removal frame 9 to move until the support ring 11 contacts the ground, which can fix the position of the soil removal frame 9. At this time, the support ring 11 is fixed to the ground by the setting of the positioning pin 13. Then the drive component 19 can be turned off and locked.
[0089] Drilling operations can now begin. The first motor 4 is turned on, driving the drill rod 3 to rotate. The third motor 34 is then turned on, causing the lead screw 35 to rotate. This causes the nut 36 to move along the axis of the lead screw 35. The telescopic protective sleeve 37 protects the lead screw 35. Under the action of the nut 36, the sliding frame 2 also moves along the axis of the lead screw 35. Thus, drilling operations can be carried out by setting up the drill rod 3.
[0090] As drilling progresses, a large amount of excavated soil enters the inner side of the soil discharge frame 9. At this time, the second motor 22 is turned on, which drives the second gear 23 to rotate. The second gear 23 drives the second gear ring 21 to rotate, which in turn drives the soil discharge frame 9 to rotate. At the same time, the second gear ring 21 and the push ring 20 rotate relative to each other. As the soil discharge frame 9 rotates, the soil discharge frame 9, through the soil collection plate 14, sends the excavated soil generated during drilling into the soil discharge trough 10, and discharges it through the soil discharge trough 10. The excavated soil discharged from the inner side of the soil discharge frame 9 will accumulate on the outer side of the soil discharge frame 9. At this time, the deflector plate 18 is used to deflect the discharged excavated soil away, thereby preventing the excavated soil discharged from the inner side of the soil discharge frame 9 from accumulating on the outer side of the soil discharge frame 9 and thus affecting the discharge of excavated soil.
[0091] As the soil discharge frame 9 rotates, the excavated soil generated during drilling is fed into the soil discharge trough 10 through the soil collection plate 14. At this time, the guide frame 15 rotates around the axis of the soil discharge frame 9 as it rotates. Through the setting of the first gear 16 of the first gear ring 17, the first gear 16 rotates, thereby assisting the excavated soil to be discharged, reducing the occurrence of excavated soil clogging in the soil discharge trough 10, and ensuring smooth discharge of excavated soil.
[0092] As drilling progresses, dust is continuously generated. At this time, the blower 29 is activated, drawing air from the dust collector 27. This air is then drawn into the dust collection trough 24 via the dust collection pipe 28, until the dust generated during drilling is sucked into the dust collection chamber. The dust then passes sequentially through the through-slot 26, the dust collection hood 25, and the dust collection pipe 28 until it enters the dust collector 27. The dust is then processed by the dust collector 27. Simultaneously, as the soil discharge frame 9 rotates, the soil collection plate 14 removes the drilling dust. Dust will also be generated during the process of sending the excavated soil into the discharge trough 10. At this time, the water source is connected to the connector 33, the water spray head 31 is turned on, and the water enters the water spray pipe 30 through the connecting pipe 32 and is sprayed out in the form of water mist through the setting of the water spray head 31, thereby suppressing the dust.
