Description

Intelligent rapid tunneling equipment for coal mine TECHNICAL FIELD

[0001] The present application relates to the technical field of tunneling equipment, in particular to an intelligent rapid tunneling equipment for coal mine. BACKGROUND

[0002] The tunneling machine is a machine for digging straight underground tunnels. In the process of coal mining, tunneling equipment is needed for coal mining. For example, in the patent with the patent number "CN220791225U" and the patent name "Coal mine tunneling machine", if a relatively solid rock cannot be drilled, the drill rod will continue to move, the protection rod will move towards the protection block, the larger force will break through the limitation of the second spring and make the clamping block retract into the protection rod, at this time the protection rod is not limited and moves towards the inside trigger rod, the trigger rod end face is provided with a switch that can stop the drill rod from running, when the protection rod contacts the trigger rod, the switch is triggered, at this time the drill rod and the drill bit stop running, thereby realizing the protection of the drill bit by stopping when encountering hard rock, and the device can be reset by moving the protection rod outward by the hydraulic rod and clamping the clamping block in the protection block, without affecting subsequent use. However, the above structure still has the following problems in actual use:

[0003] The above tunneling equipment produces a large amount of coal ash in the process of working, and the fine coal ash is easy to float with the air, thereby causing more dust in the tunnel. Since the coal ash is black, it also easily reduces the visibility of the tunnel, and the dust is easy to be inhaled by the workers, thereby causing harm to the health of the workers.

[0004] Therefore, we propose the coal mine intelligent rapid tunneling equipment which can well solve the above problems.

[0008] Further comprising: the upper surface of the vehicle body is also fixed with a mounting plate, the inner side of the mounting plate is fixed with an extension rod, and the left end of the extension rod is fixed with a tunneling head;

[0015] Preferably, the left end of the connecting clamping rod is provided in a "H" shaped structure, and the connecting clamping rod is clampedly connected with the clamping groove.

[0016] Preferably, the clamping groove is formed in the inner side of the mounting frame, and the inner end of the clamping groove penetrates to the inner side of the mounting frame, so that the connecting clamping rod can slide into the clamping groove.

[0017] Compared with the prior art, the coal mine intelligent rapid tunneling equipment can not only avoid the scattering of dust, thereby reducing the dust in the tunnel, but also avoid the problem that the dust affects the tunnel operation, and reduce the possibility of workers inhaling dust, thereby protecting the health of workers, and avoiding that large coal particles fall on the atomizing nozzle, thereby impacting the atomizing nozzle and causing damage to the atomizing nozzle, thereby reducing the number of worker maintenance and improving the service life.

[0018] (1) The water pump can suck the water in the water tank into the hose, and then the hose sends the water into the conical plate, and then the atomizing nozzle sprays the water, thereby spraying the water on the dust generated during the operation of the tunneling equipment, thereby making the water adhere to the dust, thereby increasing the weight of the dust, so that the water can fall by gravity, thereby avoiding the scattering of dust, thereby reducing the dust in the tunnel, and avoiding the problem that the dust affects the tunnel operation, and reducing the possibility of workers inhaling dust, thereby protecting the health of workers;

[0019] Further, the left side of the conical plate is provided with a mounting frame, and the inner side of the mounting frame is provided with a screen. The mesh aperture of the screen is relatively large, so it does not affect the water spraying of the atomizing nozzle.

[0020] (2) The screen mainly blocks larger coal particles that fall out during tunneling, thereby preventing larger coal particles from falling on the atomizing nozzle and causing damage to the atomizing nozzle, thereby reducing the frequency of worker maintenance and improving the service life.

[0021] (3) By pushing the push rod to the left, the push rod drives the fixed connecting rod to move to the left, so that the left end of the connecting rod is no longer connected with the clamping groove. At this time, the two groups of mounting frames can be pulled outwards to complete the disassembly of the mounting frame.

[0022] Further, the new two groups of mounting frames are then pushed inwards and the clamping grooves are slid towards the connecting rod. At this time, the push rod can be released, and the elastic force of the return spring drives the push rod to slide to the right, and the push rod drives the connecting rod to slide to the right, so that the left end of the connecting rod is connected with the clamping groove, and the mounting frame is fixed, thereby achieving the effect of replacing the mounting frame and the screen.

[0033] The tunneling equipment realizes displacement through the vehicle body 1, and realizes coal mining through the extension rod 3 fixed in the inner side of the mounting plate 2 and the cutting head 4 fixed on the front end thereof, the extension rod 3 and the cutting head 4 realize intelligent control through numerical control equipment, realize coal mining through the existing numerical control system, add water source into the water tank 9 through the water inlet 10, then start the water pump 8, so that the water pump 8 can suck the water in the water tank 9 into the hose 7, then send it into the conical plate 5 through the hose 7, and finally spray it out through the atomizing nozzle 6 fixed on the left side of the conical plate 5, so that the water can be sprayed on the dust generated during the work of the tunneling equipment, so that the water adheres to the dust, and the weight of the dust is increased, so that the water can fall by gravity, thereby avoiding the scattering of dust, thereby reducing the dust in the roadway, and avoiding the problem that the dust affects the roadway operation, and reducing the possibility of dust being inhaled by workers, protecting the health of workers, and the size of the dust can be sensed by installing a dust sensor, and the threshold of the dust sensor can be set through PLC controller programming, so that the amount of water sprayed by the atomizing nozzle 6 can be adjusted according to the amount of dust, so that the atomizing nozzle 6 can achieve the best suppression effect on the dust, and the intelligent mining of the tunneling equipment is realized;

[0034] Embodiment two: different from embodiment one, this embodiment avoids that the larger coal particles fall on the atomizing nozzle 6, and then impact and damage the atomizing nozzle 6, for details, refer to FIG. 1-4, the left side of the conical plate 5 is provided with the mounting frame 11, and the mounting frame 11 is provided with two groups, and the two groups of mounting frames 11 are arranged in a circular structure, the inner side of the mounting frame 11 is fixed with the screen 12, and the aperture of the screen 12 is 1-3 cm;

[0035] Meanwhile, an installation frame 11 is installed on the left side of the conical plate 5. An isolation net 12 is arranged inside the installation frame 11. The aperture of the mesh holes of the isolation net 12 is relatively large, so it will not affect the water spraying of the atomizing nozzle 6. At the same time, the isolation net 12 mainly blocks the larger coal particles ejected during the tunneling work, thereby preventing the larger coal particles from hitting the atomizing nozzle 6, hitting the atomizing nozzle 6 and causing damage to the atomizing nozzle 6, reducing the maintenance frequency of workers, and increasing its service life.

[0036] Embodiment 3: Different from Embodiment 2, this embodiment achieves the effect of replacing the installation frame 11 and the isolation net 12. Specifically, refer to FIGS. 4-6.

[0037] Meanwhile, when the installation frame 11 and the isolation net 12 need to be replaced, only need to push the push rod 13 to the left side, so that the push rod 13带动 the fixed connecting clamping rod 15 to move to the left side together, so that the left end of the connecting clamping rod 15 slides to the left side in the clamping groove 16, so that the left end of the connecting clamping rod 15 no longer forms a snap - fit connection with the clamping groove 16. At this time, the two installation frames 11 can be respectively pulled to the outside to complete the disassembly work of the installation frame 11. At the same time, align the two new installation frames 11 with the connecting clamping rods 15, then push the two installation frames 11 to the inside, causing the two installation frames 11 to contact each other, so that the installation frame 11带动 the clamping groove 16 to slide towards the connecting clamping rod 15. At this time, release the push rod 13, and through the elastic force of the return spring 14,带动 the push rod 13 to slide to the right side, so that the push rod 13带动 the connecting clamping rod 15 to slide to the right side together, so that the left end of the connecting clamping rod 15 realizes snap - fit with the clamping groove 16, and then completes the fixation of the installation frame 11, thus achieving the effect of replacing the installation frame 11 and the isolation net 12.
