Description

TECHNICAL FIELD

[0001] The present application relates to the field of coal mines, in particular to a coal mine rapid tunneling auxiliary device and system. BACKGROUND

[0002] The existing coal mine tunneling machine mines through a tunneling head, and the material falling down is loaded into the conveying belt of the tunneling machine through the shovel plate part with a star wheel. When the tunneling head mines, a spray pipe is generally arranged around the tunneling head to settle the dust generated during tunneling. However, when the material is pushed onto the conveying belt through the rotating star wheel, dust is also generated. The tunneling head moves to mine, causing the spray pipe on the tunneling head to also move, so that the dust on the conveying belt cannot be effectively settled. Therefore, the present application provides a coal mine rapid tunneling auxiliary device. SUMMARY

[0003] Based on the above problems, the present application provides a coal mine rapid tunneling auxiliary device and system, which solves the technical problem that the existing spray device cannot settle the dust on the conveying belt. In the present application, the dust settling assembly directly sprays the conveying belt in the middle of the star wheel, so that the dust on the conveying belt is quickly settled.

[0004] The present application provides a coal mine rapid tunneling auxiliary device, which comprises:

[0005] a mounting cylinder, a plurality of spray pipes, a transfer disc, a water supply pipe, two groups of transmission pipes, two groups of connecting assemblies, and a dust settling assembly;

[0006] The external tunneling head is mounted in the mounting cylinder, and the transfer disc is fixedly connected to the mounting cylinder. The mounting cylinder is uniformly circumferentially mounted with spray pipes, one side of the spray pipes is exposed, and the other side is in communication with one side of the transfer disc. The other side of the transfer disc is in communication with the water supply pipe, and the water supply pipe is connected to a water source. The front and rear sides of the transfer disc are in communication with the transmission pipes, and the distal ends of the two groups of transmission pipes are in communication with the dust settling assembly connected to the connecting assembly.

[0007] When the tunneling head moves, the water supply pipe sends water into the transfer disc, and the transfer disc sends the water into the spray pipes. The spray pipes move with the tunneling head to spray the mining site, and the dust settling assembly sprays the conveying belt in the middle of the external star wheel through the transmission pipes.

[0008] In addition, the connecting assembly comprises a connecting plate and an eccentric collar. The connecting plate is fixedly connected to the top end of the drive shaft of the star wheel, and the top of the connecting plate is fixedly connected to the outer ring of the fixed bearing. The outer ring of the fixed bearing is sleeved with the eccentric collar.

[0009] When the star wheel works, the drive shaft drives the connecting plate to rotate, so that the outer ring of the fixed bearing drives the eccentric collar to rotate.

[0010] In addition, the dust suppression components include support rods, rotating shafts, mounting brackets, connecting pipes, nozzles, and protective covers;

[0011] The support rod is set on the inner ring of the fixed bearing. The support rod is rotatably connected to the rotating shaft through the fixed bearing. Both ends of the rotating shaft are fixedly connected to the mounting bracket. The mounting bracket is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the transmission pipe. The connecting pipe is connected to the nozzle. The nozzle passes through the protective cover. The inner wall of the protective cover is provided with a connecting rod that is connected to the support rod.

[0012] In addition, the dust suppression components also include: missing gears and drive frame;

[0013] The protective cover has a through groove that matches the nozzle. The front and rear sides of the rotating shaft are fitted with gears, and the top of the gears are meshed with the drive frame. One end of the drive frame passes through the protective cover, so that the protective cover guides the drive frame. The other end of the drive frame is equipped with a spring connected to the protective cover. The spring drives the drive frame to return to its original position. The bottom of the drive frame is rotatably connected to a wheel axle through a bearing, and a rotating wheel is fitted at the bottom end of the wheel axle.

[0014] The eccentric collar pushes the rotating wheel to move laterally, causing the drive frame to rotate back and forth with the missing gear, which in turn causes the mounting bracket on the rotating shaft to swing back and forth, thus causing the nozzle to move back and forth on the through groove of the protective cover.

[0015] In addition, the through groove has a fan-shaped structure, and the nozzle passes through the through groove when it rotates. The protective cover has a round hole that matches the connecting pipe, and the connecting pipe passes through the round hole.

[0016] In addition, the outer ring of the rotating wheel is rolledly connected to the outer wall of the eccentric collar, so that when the eccentric collar rotates, it can squeeze the rotating wheel. The nozzle is fixedly connected to the mounting bracket, so that when the mounting bracket rotates, the nozzle can rotate with it.

[0017] In addition, there are two sets of nozzles, which are set on opposite sides to spray dust onto the conveyor belt between the two star wheels.

[0018] In addition, when the tunneling head is mining the working face, water mist is sprayed through the spray pipe to suppress dust. When the star wheel starts to rotate and propel the material, the connecting plate drives the outer ring of the fixed bearing to rotate, so that the support rod does not rotate. This allows the transmission pipe to send water into the connecting pipe, and then sprays water onto the conveyor belt through two sets of nozzles to suppress dust. When the outer ring of the fixed bearing rotates, the eccentric collar pushes the rotating wheel to move laterally, causing the drive frame to drive the missing gear 79 to rotate back and forth, which in turn causes the mounting bracket on the rotating shaft to swing back and forth, so that the nozzle moves back and forth on the through groove of the protective cover.

[0019] In addition, valves are installed on both sets of transmission pipes. When the star wheel is not rotating, the valves are closed, and only the spray pipe is working.

[0020] The present invention also proposes a system for a rapid tunneling auxiliary device for coal mines as described in any of the preceding claims, further comprising: a tunneling head disposed within an installation cylinder.

[0021] This invention provides a spray pipe and dust suppression assembly for spraying dust generated during tunneling operations, solving the technical problem that existing spray devices cannot settle dust on conveyor belts. In this invention, the dust suppression assembly directly sprays the conveyor belt in the center of the star wheel, enabling rapid settling of dust on the conveyor belt. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. This description is intended only to illustrate specific embodiments of the invention and does not constitute any limitation on the invention. The scope of protection of the invention is defined by the claims.

[0028] Reference Figure 1 This invention proposes a rapid tunneling auxiliary device for coal mines, comprising:

[0029] 1. Mounting cylinder; 2. Multiple spray pipes; 3. Central turntable; 4. Water supply pipe; 5. Two sets of transmission pipes; 6. Two sets of connecting components; and 7. Dust suppression components.

[0030] An external tunneling head is installed inside the mounting cylinder 1. The central turntable 3 is fixedly connected to the mounting cylinder 1. Spray pipes 2 are evenly and circumferentially installed inside the mounting cylinder 1. One side of the spray pipes 2 is exposed, and the other side is connected to one side of the central turntable 3. The other side of the central turntable 3 is connected to a water supply pipe 4, which is connected to an external water source. The front and rear sides of the central turntable 3 are connected to transmission pipes 5. The ends of the two sets of transmission pipes 5 that are far apart from each other are connected to a dust suppression component 7 connected to the connecting component 6.

[0031] When the tunneling head moves, the water supply pipe 4 delivers water into the central turntable 3, and the central turntable 3 delivers water into the spray pipe 2. The spray pipe 2 follows the movement of the tunneling head to spray the mining area. The dust suppression component 7 sprays the conveyor belt in the middle of the external star wheel through the transmission pipe 5.

[0032] In this embodiment, the two sets of connecting components 6 in the rapid coal mine tunneling auxiliary device have identical structures. The tunneling head is installed inside the mounting cylinder 1 and can rotate inside the mounting cylinder 1 to mine the working face. Spray pipes 2 are evenly and circumferentially installed inside the mounting cylinder 1 to suppress dust generated by the conveyor belt.

[0033] The other side of the turntable 3 is connected to a water supply pipe 4, which is connected to an external water source, so that the turntable 3 can send water into the spray pipe 2, and then spray the mining area by following the movement of the tunneling head through the spray pipe 2.

[0034] The front and rear sides of the turntable 3 are connected to transmission pipes 5. The ends of the two sets of transmission pipes 5 that are far apart from each other are connected to dust suppression components 7 connected to the connecting components 6. Through the transmission pipes 5, the dust suppression components 7 can spray the conveyor belt in the middle of the star wheel.

[0035] This embodiment provides a spray pipe 2 and a dust suppression component 7 to spray dust generated during tunneling operations, solving the technical problem that existing spray devices cannot settle dust on the conveyor belt. In this embodiment, the dust on the conveyor belt is rapidly settled by directly spraying the dust suppression component onto the conveyor belt in the center of the star wheel.

[0036] Reference Figure 2 and Figure 3 In one embodiment, the connecting component 6 includes a connecting plate 61 and an eccentric collar 63. The connecting plate 61 is fixedly connected to the top of the drive shaft of the star wheel, and the top of the connecting plate 61 is fixedly connected to the outer ring of the fixed bearing 62. The outer ring of the fixed bearing 62 is fitted with the eccentric collar 63.

[0037] When the star wheel is working, the drive shaft drives the connecting plate 61 to rotate, which causes the outer ring of the fixed bearing 62 to drive the eccentric collar 63 to rotate.

[0038] The dust suppression assembly is made to work normally by connecting the components. The connecting plate 61 is rotated by the drive shaft, which causes the outer ring of the fixed bearing 62 to rotate the eccentric collar 63, and finally drives the movement of the dust suppression assembly 7.

[0039] In one embodiment, the dust suppression assembly 7 includes a support rod 71, a rotating shaft 72, a mounting bracket 73, a connecting pipe 74, a nozzle 75, and a protective cover 76;

[0040] The support rod 71 is mounted on the inner ring of the fixed bearing 62. The support rod 71 is rotatably connected to the rotating shaft 72 through the fixed bearing 62. Both ends of the rotating shaft 72 are fixedly connected to the mounting bracket 73. The mounting bracket 73 is connected to one end of the connecting pipe 74, and the other end of the connecting pipe 74 is connected to the transmission pipe 5. The connecting pipe 74 is connected to the nozzle 75. The nozzle 75 passes through the protective cover 76. The inner wall of the protective cover 76 is provided with a connecting rod 78 connected to the support rod 71.

[0041] Reference Figure 2 and Figure 3 In one embodiment, the dust suppression assembly 7 further includes: a missing gear 79 and a drive frame 710;

[0042] The protective cover 76 has a through groove 77 that matches the nozzle 75. The front and rear sides of the rotating shaft 72 are fitted with missing gears 79. The top of the missing gears 79 are meshed with the drive frame 710. One end of the drive frame 710 passes through the protective cover 76, so that the protective cover 76 guides the drive frame 710. The other end of the drive frame 710 is provided with a spring 711 connected to the protective cover 76. The spring 711 drives the drive frame 710 to return to its original position. The bottom of the drive frame 710 is rotatably connected to a wheel axle through a bearing, and a rotating wheel 712 is fitted at the bottom end of the wheel axle.

[0043] The eccentric collar 63 pushes the rotating wheel 712 to move laterally, causing the drive frame 710 to drive the missing gear 79 to rotate back and forth, which in turn causes the mounting bracket 73 on the rotating shaft 72 to swing back and forth, thereby causing the nozzle 75 to move back and forth on the through groove 77 of the protective cover 76.

[0044] The through groove 77 allows the nozzle 75 to move back and forth, thereby increasing the spraying area.

[0045] In one embodiment, the through groove 77 has a fan-shaped structure, and the nozzle 75 passes through the through groove 77 when rotating. The protective cover 76 has a round hole that matches the connecting pipe 74, and the connecting pipe 74 passes through the round hole.

[0046] In one embodiment, the outer ring of the rotating wheel 712 is rolledly connected to the outer wall of the eccentric collar 63, so that when the eccentric collar 63 rotates, it can squeeze the rotating wheel 712. The nozzle 75 is fixedly connected to the mounting bracket 73, so that when the mounting bracket 73 rotates, the nozzle 75 can rotate with it.

[0047] In one embodiment, there are two sets of nozzles 75, which are arranged on opposite sides to spray dust onto the conveyor belt between the two sets of star wheels.

[0048] In one embodiment, when the tunneling head is mining the working face, water mist is sprayed through the spray pipe 2 to suppress dust. When the star wheel starts to rotate and propel the material, the connecting plate 61 drives the outer ring of the fixed bearing 62 to rotate, so that the support rod 71 does not rotate. This allows the transmission pipe 5 to send water into the connecting pipe 74, thereby spraying water onto the conveyor belt through two sets of nozzles 75 to suppress dust. When the outer ring of the fixed bearing 62 rotates, the eccentric collar 63 pushes the rotating wheel 712 to move laterally, causing the drive frame 710 to drive the missing gear 79 to rotate back and forth. This causes the mounting bracket 73 on the rotating shaft 72 to swing back and forth, so that the nozzles 75 move back and forth on the through groove 77 of the protective cover 76. This embodiment expands the range of dust suppression on the conveyor belt and improves the dust treatment efficiency during rapid tunneling in coal mines.

[0049] In one embodiment, valves are provided on both sets of transmission pipes 5. When the star wheel is not rotating, the valves are closed, and only the spray pipe 2 is working.

[0050] The present invention also proposes a system for a rapid tunneling auxiliary device for coal mines as described in any of the preceding claims, further comprising: a tunneling head disposed within the mounting cylinder 1.

[0051] In this embodiment, the two sets of connecting components 6 in the rapid coal mine tunneling auxiliary device have identical structures. The tunneling head is installed inside the mounting cylinder 1 and can rotate inside the mounting cylinder 1 to mine the working face. Spray pipes 2 are evenly and circumferentially installed inside the mounting cylinder 1 to suppress dust generated by the conveyor belt.

[0052] The other side of the turntable 3 is connected to a water supply pipe 4, which is connected to an external water source, so that the turntable 3 can send water into the spray pipe 2, and then spray the mining area by following the movement of the tunneling head through the spray pipe 2.

[0053] The front and rear sides of the turntable 3 are connected to transmission pipes 5. The ends of the two sets of transmission pipes 5 that are far apart from each other are connected to dust suppression components 7 connected to the connecting components 6. Through the transmission pipes 5, the dust suppression components 7 can spray the conveyor belt in the middle of the star wheel.

[0054] This embodiment provides a spray pipe 2 and a dust suppression component 7 to spray dust generated during tunneling operations, solving the technical problem that existing spray devices cannot settle dust on the conveyor belt. In this embodiment, the dust on the conveyor belt is rapidly settled by directly spraying the dust suppression component onto the conveyor belt in the center of the star wheel.

[0055] The above description is merely the principle and preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
