Technical Field
[0001] This invention belongs to the field of drilling equipment technology, specifically a rapid drilling device for mine collapse life channels. Background Technology
[0002] After a mine collapse, underground workers are often trapped in an enclosed space by the collapsed rock mass. Specialized drilling equipment is needed to quickly drill out a life-saving passage so that the trapped workers can be rescued later.
[0003] Existing mine rescue drilling equipment has relatively limited functionality, with most only possessing basic drilling capabilities. After drilling is completed, it is difficult to simultaneously detect life signals in the trapped area, making it impossible to quickly and accurately determine whether there are trapped personnel. Furthermore, it is difficult to reliably deliver emergency supplies such as nutrient solutions, medicines, and communication equipment underground, resulting in insufficient timeliness and targeting of rescue efforts. Consequently, it fails to meet the actual needs for rapid, efficient, and safe rescue in mine collapse accidents. Summary of the Invention
[0004] In response to the above situation and to overcome the shortcomings of the existing technology, the present invention provides a rapid drilling device for mine collapse life channels, which effectively solves the problem that the current technology cannot meet the actual needs of rapid, efficient and safe rescue in mine collapse accidents.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid drilling device for mine collapse life channels, including an installation rod, one end of which is provided with a drilling mechanism, multiple side grooves are provided at equal angles on the outer side of the installation rod, each side groove is provided with a flipping mechanism, and multiple conveying channels are provided at equal angles on the installation rod, each conveying channel being connected to each side groove respectively. The flipping mechanism includes an outer frame fixed to the outside of the mounting rod, a sealing plate rotatably connected to the inside of the outer frame, the sealing plate being located in the side groove, a radar life detection sensor being fixedly connected to the side of the sealing plate near the side groove, an L-shaped plate being fixedly connected to the inside of the side groove, a walkie-talkie being fixedly connected to the L-shaped plate, a receiving box being provided inside the side groove, two support columns being symmetrically fixedly connected between the receiving box and the inner wall of the side groove, and a cover plate being hinged to the outside of the receiving box.
[0006] Preferably, a second magnet is fixedly connected to the side of the sealing plate near the side groove, and a first magnet is fixedly connected to the L-shaped plate, with the magnetic poles of the first magnet and the second magnet having opposite poles.
[0007] Preferably, an arc-shaped block is fixedly connected to the side of the sealing plate near the side groove. A limiting hole is provided on the outer side of the arc-shaped block. A side plate is provided on the inner side of the side groove. A side roller is rotatably connected to the side plate. The side roller abuts against the arc-shaped block. A limiting rod is fixedly connected to the side plate. The outer diameter of the limiting rod is equal to the inner diameter of the limiting hole.
[0008] Preferably, the drilling mechanism includes a side cylinder fixed to one end of the mounting rod, a movable cylinder movably sleeved on the outer side of the side cylinder, a drill rod fixedly connected to one end of the mounting rod, the side cylinder and the movable cylinder being located on the outer side of the drill rod, and the end of the drill rod away from the mounting rod extending to the outer side of the movable cylinder and fixedly connected to a tip.
[0009] Preferably, an inner ring is fixedly connected to the inner side of the movable cylinder, and the side plate is fixedly connected to the inner ring.
[0010] Preferably, two L-shaped round rods are symmetrically fixedly connected to the inner side of the side cylinder, and a U-shaped plate is movably sleeved on the outer side of each of the two L-shaped round rods. Both U-shaped plates are fixedly connected to the inner ring, and springs are fixedly connected between the two U-shaped plates and the side cylinder. The two springs are respectively sleeved on the outer side of the two L-shaped round rods.
[0011] Preferably, a spiral blade is fixedly connected to the outer side of the drill rod, and multiple arc-shaped blades are fixedly connected at equal angles on the arc-shaped surface of the movable cylinder.
[0012] Preferably, an outer ring is fixedly sleeved on the outer side of the drill rod, a sealing ring one is fixedly connected to the side of the outer ring away from the inner ring, and a sealing ring two is fixedly connected to the end of the side cylinder away from the mounting rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention facilitates the movement of the movable cylinder under force when drilling into media such as coal and rock masses and concrete using a drill rod. This allows the side roller to separate from the arc-shaped block, facilitating the rotation of the sealing plate to bring magnet two into contact with magnet one and attract them. It also allows the limiting rod to be inserted into the limiting hole to fix the sealing plate, facilitating the sealing of the side groove. When the small hole of the life channel is drilled through, the limiting rod can be removed from the limiting hole under the action of the spring force, allowing the side roller to roll on the arc-shaped block. This facilitates the separation of magnet two from magnet one, allowing the sealing plate to rotate and open. Through the cooperation between the radar life detection sensor and the walkie-talkie, the location and survival status of trapped personnel can be quickly confirmed. At the same time, it facilitates the opening of the cover to retrieve emergency supplies in the container box, thereby meeting the actual needs of rapid, efficient, and safe rescue in mine collapse accidents.
[0015] 2. This invention improves drilling efficiency by setting helical blades on the outside of the drill rod and arc-shaped blades on the arc-shaped surface of the movable cylinder.
[0016] 3. When drilling into media such as coal, rock, and concrete using the drill rod, this invention facilitates the movement of the movable cylinder under stress, allowing the movable cylinder and inner ring to fit into sealing ring one and sealing ring two respectively. This ensures the sealing between the movable cylinder and the side cylinder, as well as between the movable cylinder and the drill rod, preventing debris from entering the side cylinder and the movable cylinder. When the sealing plate rotates and closes, it fits into the sealing frame, thus preventing debris from entering the side groove. Attached Figure Description

[0020] 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.
[0021] Example 1, by Figures 1-6 The present invention relates to a rapid drilling device for a life passage in a mine collapse, comprising a mounting rod 1, a drilling mechanism 3 at one end of the mounting rod 1, multiple side grooves 4 at equal angles on the outer side of the mounting rod 1, each side groove 4 being provided with a flipping mechanism 2, and multiple conveying channels 6 at equal angles on the mounting rod 1, each conveying channel 6 being connected to each side groove 4. When the life passage hole is drilled through, oxygen can be introduced into the side groove 4 through the conveying channel 6 to provide oxygen to the trapped personnel.
[0022] In Embodiment Two, based on Embodiment One, the flipping mechanism 2 includes an outer frame 201 fixed to the outside of the mounting rod 1. A sealing plate 2015 is rotatably connected to the inner side of the outer frame 201. The sealing plate 2015 is located at the side groove 4. A radar life detection sensor 2011 is fixedly connected to the side of the sealing plate 2015 near the side groove 4. An L-shaped plate 206 is fixedly connected to the inner side of the side groove 4. A walkie-talkie 207 is fixedly connected to the L-shaped plate 206. The radar life detection sensor 2011 detects weak vital signs signals generated by the breathing and heartbeat of the trapped person by emitting and receiving reflected electromagnetic waves. The walkie-talkie 207 communicates wirelessly. This system enables two-way voice communication between personnel trapped above and below ground. The two systems working together can quickly confirm the location and survival status of trapped personnel. A storage box 205 is located inside the side channel 4, which can hold emergency supplies such as water, food, medicine, and nutrient solutions. Two support columns 204 are symmetrically fixedly connected between the storage box 205 and the inner wall of the side channel 4. A cover plate 209 is hinged to the outside of the storage box 205. A magnet 2012 is fixedly connected to the sealing plate 2015 near the side channel 4. A magnet 208 is fixedly connected to the L-shaped plate 206. The magnetic poles of magnet 208 and magnet 2012 are opposite. The sealing plate 2015 is located near the side channel 4. An arc-shaped block 2014 is fixedly connected to one side of the side groove 4. A limiting hole 2013 is provided on the outer side of the arc-shaped block 2014. A side plate 203 is provided on the inner side of the side groove 4. A side roller 202 is rotatably connected to the side plate 203. The side roller 202 abuts against the arc-shaped block 2014. A limiting rod 2010 is fixedly connected to the side plate 203. The outer diameter of the limiting rod 2010 is equal to the inner diameter of the limiting hole 2013. The drilling mechanism 3 includes a side cylinder 301 fixed to one end of the mounting rod 1. A movable cylinder 302 is movably sleeved on the outer side of the side cylinder 301. A drill rod 304 is fixedly connected to one end of the mounting rod 1. The side cylinder 301 and the movable cylinder 302 are both located on the drill rod 304. On the outside, the end of the drill rod 304 away from the mounting rod 1 extends to the outside of the movable cylinder 302 and is fixedly connected to the tip 303. The inner side of the movable cylinder 302 is fixedly connected to the inner ring 309. The side plate 203 is fixedly connected to the inner ring 309. Two L-shaped round rods 3013 are symmetrically fixedly connected to the inner side of the side cylinder 301. U-shaped plates 3012 are movably sleeved on the outer side of the two L-shaped round rods 3013. The two U-shaped plates 3012 are fixedly connected to the inner ring 309. Springs 3011 are fixedly connected between the two U-shaped plates 3012 and the side cylinder 301. The two springs 3011 are respectively sleeved on the outer side of the two L-shaped round rods 3013. First, when the drill rod 304 rotates and propels to drill through media such as coal, rock, and concrete, the movable cylinder 302 deforms under stress, causing the inner ring 309 to move. At the same time, the two U-shaped plates 3012 slide along the two L-shaped round rods 3013 respectively, and the two springs 3011 deform. When the inner ring 309 moves, it drives the side plate 203 to move, and drives the side roller 202 to move and separate from the arc block 2014. At this time, the sealing plate 2015 can be rotated to close. At this time, the second magnet 2012 and the first magnet 208 come into contact with each other and attract each other, realizing the initial locking of the sealing plate 2015. The side plate 203 continues to move until the limiting rod 2010 is inserted into the limiting hole 2013, realizing the firm fixation of the sealing plate 2015 and sealing the side groove 4. When the small hole in the life passage is drilled through, the side groove 4 is located in the trapped area, and the force on the movable cylinder 302 disappears. At this time, the two springs 3011 reset and drive the inner ring 309 to move, which in turn drives the side plate 203 to move, so that the limiting rod 2010 is removed from the limiting hole 2013, releasing the fixation on the sealing plate 2015. At the same time, the side roller 202 rolls on the arc block 2014 and pushes the sealing plate 2015 to flip and open. At the same time, the second magnet 2012 separates from the first magnet 208. At this time, the location and survival status of the trapped personnel can be quickly confirmed through the cooperation between the radar life detection sensor 2011 and the walkie-talkie 207. Meanwhile, the trapped personnel can open the cover plate 209 to take out the emergency supplies in the container box 205. Therefore, it meets the actual needs of rapid, efficient and safe rescue in mine collapse accidents.
[0023] In Example 3, based on Example 1, a spiral blade 305 is fixedly connected to the outer side of the drill rod 304, and multiple arc-shaped blades 306 are fixedly connected at equal angles on the arc-shaped surface of the movable cylinder 302. The arc-shaped blade 306 can continuously cut and crush media such as coal, rock, and concrete, improving drilling and rock breaking efficiency. The spiral blade 305 can promptly transport and discharge the rock slag and debris generated during cutting, effectively preventing slag blockage and drill bit jamming in the hole, making the drilling process smoother. At the same time, it reduces the wear of the drill rod 304, ensuring the rapid and stable drilling of the life channel.
[0024] In Example 4, based on Example 1, an outer ring 3010 is fixedly sleeved on the outside of the drill rod 304. A sealing ring 307 is fixedly connected to the side of the outer ring 3010 away from the inner ring 309. A sealing ring 308 is fixedly connected to the end of the side cylinder 301 away from the mounting rod 1. A sealing frame 5 is fixedly connected to the outside of the mounting rod 1. The sealing frame 5 is set at the side groove 4. The sealing frame 5, the sealing ring 307 and the sealing ring 308 are all made of rubber. When the drill rod 304 rotates and advances to drill through media such as coal, rock, and concrete, the movable cylinder 302 moves under force, which in turn moves the inner ring 309 until the movable cylinder 302 is in contact with the sealing ring 307 and the inner ring 309 is in contact with the sealing ring 308. This ensures the sealing between the movable cylinder 302 and the side cylinder 301, as well as between the movable cylinder 302 and the drill rod 304, preventing debris from entering the side cylinder 301 and the movable cylinder 302. When the sealing plate 2015 rotates and closes, it can be in contact with the sealing frame 5 to seal the side groove 4 and prevent debris from entering the side groove 4.
