Description

Technical Field

[0001] This utility model relates to the field of tunnel dust removal technology, and in particular to a mine walking spray system. Background Technology

[0002] In mining operations, the mine dust removal system is of paramount importance, ranking first among the "six major systems" of a mine. This system not only provides clean air to the mine and protects the health of miners, but also plays a key role in solving safety issues such as gas accumulation, dust accumulation, and high temperatures.

[0003] Currently, the main method of dust control in coal mines is to install dust suppression nozzles at locations where dust concentrations exceed standards. For example, Chinese utility model patent CN216277980U discloses a roadway spray dust suppression structure comprising multiple spray pipes connected to a pressure-bearing pipe. A booster pump on the pressure-bearing pipe regulates the flow rate of the spray pipes, and multiple atomizing nozzles are installed on the spray pipes. During operation, water flows sequentially through the booster pump, the pressure-bearing pipe, and the spray pipes, finally being sprayed out by the atomizing nozzles. This structure utilizes nozzle spraying to achieve dust suppression to a certain extent, and by regulating the water flow through components such as the booster pump, the spraying effect can be adjusted according to actual conditions.

[0004] However, this existing tunnel dust removal structure still has certain drawbacks: due to the large number of nozzles installed, the water consumption during operation is extremely high, which will cause unnecessary waste of water resources. Utility Model Content

[0005] This application provides a mine walking spray system, which solves the technical problem of high water consumption and serious water waste caused by the large number of nozzles in the existing roadway dust removal structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution, including a water supply pipe, one end of which is connected to a water source, and the other end of which is connected to a flushing spray mechanism. It also includes a track installed on the top of the tunnel, the length direction of which is consistent with the extension direction of the tunnel. A slide is fitted on the track, the bottom of which is connected to the flushing spray mechanism. A steel wire rope is connected to one side of the slide, and the steel wire rope extends along the length direction of the track. The end of the steel wire rope away from the slide is connected to a gravity traction block through a pulley system.

[0007] Because one end of the water supply pipe is connected to a water source and the other end to a flushing spray mechanism, which is connected to a track via a slide, and the slide is connected to a gravity traction block via a steel wire rope, when the system is working, the gravity traction block descends under the action of gravity, pulling the steel wire rope and causing the slide to move along the track, thereby moving the flushing spray mechanism within the tunnel. Compared to traditional dust removal methods with fixed nozzles, this reduces the number of nozzles used, lowers water consumption, and avoids unnecessary waste of water resources.

[0008] As a further improvement to the above solution, the mine walking spray system also includes a water pipe winding mechanism. The water pipe winding mechanism includes a turntable, a bushing installed at the center of the turntable, and a rotating shaft fitted inside the bushing. The rotating shaft can be fixed to the inner wall of the roadway. End plates are installed on the two end faces of the turntable, and the water pipe is wound around the outside of the turntable and located between the two end plates. The water pipe winding mechanism can avoid the water pipe from being randomly distributed in the roadway and reduce the risk of the water pipe being damaged.

[0009] As a further improvement to the above solution, the water pipe winding mechanism also includes a pneumatic motor. The output end of the pneumatic motor is connected to a motor reducer, and the output end of the motor reducer is connected to the turntable through a flexible transmission component. The pneumatic motor can provide power to the water pipe winding mechanism, driving the turntable to rotate and realize the winding of the water pipe.

[0010] As a further improvement to the above solution, a first pulley is installed at the output end of the motor reducer, and a second pulley is installed on the outside of the rotating shaft. The first pulley and the second pulley are connected by a transmission belt.

[0011] As a further improvement to the above scheme, the track is installed on the top of the tunnel by a hanger, the slide is U-shaped, and the inside of the slot of the slide is equipped with traveling wheels on both sides, and the traveling wheels on both sides of the slide cooperate with the two sides of the upper surface of the track respectively.

[0012] As a further improvement to the above solution, the flushing spray mechanism includes a flushing spray bar and a flushing spray head. The upper end of the flushing spray bar is fixedly connected to the bottom of the slide, and the lower end of the flushing spray bar is fixedly connected to the flushing spray head. The flushing spray head is connected to the water supply pipe.

[0013] As a further improvement to the above scheme, switching baffle I and switching baffle II are respectively installed below the top of the tunnel corresponding to both ends of the track. Switching baffle I and switching baffle II can be fixed to the inner wall of the tunnel. A ball valve is installed on the water supply pipe. The valve body of the ball valve is fixedly connected to the flushing spray rod. The valve rod of the ball valve includes rod body I and rod body II. One end of rod body I is perpendicularly connected to one end of rod body II. The other end of rod body I and the other end of rod body II can respectively contact switching baffle I and switching baffle II. Thus, when the flushing spray mechanism reaches the end of the track, the valve rod of the ball valve can be rotated by the contact between rod body I and switching baffle I or the contact between rod body II and switching baffle II, thereby automatically controlling the opening and closing of the ball valve.

[0014] As a further improvement to the above scheme, a guide wheel I is installed on the outside of one end of the track along the length direction of the track. The water supply pipe passes over the top of the guide wheel I and connects to the flushing spray mechanism. A guide wheel II is installed on the outside of the other end of the track along the length direction of the track. The end of the wire rope away from the slide passes under the guide wheel II. The guide wheel I can guide the water supply pipe to keep it in a good extended and bent state and avoid twisting or excessive wear. The guide wheel II can guide the wire rope to keep the extension direction of the wire rope consistent with the length direction of the track and ensure that the slide moves smoothly and steadily.

[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages:

[0016] Because one end of the water supply pipe is connected to a water source and the other end to a flushing spray mechanism, which is connected to a track via a slide, and the slide is connected to a gravity traction block via a steel wire rope, when the system is working, the gravity traction block descends under the action of gravity, pulling the steel wire rope and causing the slide to move along the track, thereby moving the flushing spray mechanism within the tunnel. Compared to traditional dust removal methods with fixed nozzles, this reduces the number of nozzles used, lowers water consumption, and avoids unnecessary waste of water resources.

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0023] This utility model discloses a mine walking spray system, such as Figures 1 to 3 As shown, it includes a water supply pipe 1, one end of which is connected to a water source, and the other end of which is connected to a flushing spray mechanism. It also includes a track 2 installed on the top of the tunnel, the length direction of which is consistent with the extension direction of the tunnel. A slide 3 is fitted on the track 2, the bottom of which is connected to the flushing spray mechanism. A steel wire rope 4 is connected to one side of the slide 3, and the steel wire rope 4 extends along the length direction of the track 2. The end of the steel wire rope 4 away from the slide 3 is connected to a gravity traction block 6 through a pulley block 5.

[0024] In this embodiment, as Figure 1 As shown, track 2 is a long strip structure, and slide 3 is a block structure that slides in conjunction with track 2. The function of slide 3 is to drive the movement of the flushing spray mechanism through its own movement. In actual operation, water pipe 1 is connected to a water source, and the water source valve is opened, allowing water to flow to the flushing spray mechanism through water pipe 1. Gravity traction block 6 descends under the action of gravity, pulling steel wire rope 4, causing slide 3 to move along track 2 towards the side of gravity traction block 6. At this time, the flushing spray mechanism moves accordingly and sprays dust to suppress the roadway. When slide 3 moves to one end of track 2, the corresponding control mechanism is triggered, which can change the movement direction of slide 3 or shut down the spray system, completing the dust suppression work in a certain area. It should be understood that an electronic control device can be used to realize the reversal of slide 3 and flushing spray mechanism. Using an electronic control device to process signals and control equipment actions is the basic mode of automation control, which is well known to those skilled in the art, and therefore will not be elaborated upon.

[0025] In the above structure, by setting up the track 2, the slide 3, the wire rope 4 and the gravity traction block 6, the scouring spray mechanism is moved in the roadway by gravity traction. Compared with the traditional dust removal method with fixed nozzles, the number of nozzles used is reduced, water consumption is reduced, and unnecessary waste of water resources is avoided. At the same time, through the cooperation of the slide 3 and the track 2, the moving spray mechanism can more comprehensively cover the roadway space and improve dust removal efficiency.

[0026] like Figure 1As shown, along the length of track 2, a guide wheel I 24 is provided on the outside of one end of track 2, and the water pipe 1 passes over the top of the guide wheel I 24 and is connected to the flushing spray mechanism; a guide wheel II 25 is provided on the outside of the other end of track 2 along the length of track 2, and the end of the wire rope 4 away from the slide 3 passes under the guide wheel II 25.

[0027] In this embodiment, both guide wheels I 24 and II 25 are circular rollers and can be fixed to the inner wall of the tunnel via brackets. Guide wheel I 24 guides the water pipe 1, ensuring it maintains good extension and bending during movement with the spray mechanism, preventing twisting or excessive wear. Guide wheel II 25 guides the wire rope 4, ensuring its extension direction aligns with the length direction of the track. The arrangement of guide wheels I 24 and II 25 optimizes the movement trajectory of the water pipe 1 and wire rope 4, improving the overall stability and reliability of the spray system.

[0028] In addition, the mining walking spray system disclosed in this utility model also includes a water pipe winding mechanism. The water pipe winding mechanism includes a turntable 7, a bushing 8 installed at the center of the turntable 7, a bushing 801 fitted inside the bushing 8, and the bushing 801 can be fixed to the inner wall of the roadway. End plates 9 are respectively installed on the two end faces of the turntable 7, and the water pipe is wound around the outside of the turntable 7 and located between the two end plates 9.

[0029] In this embodiment, as Figure 2 As shown, the turntable 7 has a disc-shaped structure, and the bushing 8 is fixedly installed at the center of the turntable 7. The rotating shaft 801 is installed through the inside of the bushing 8 to ensure that the turntable 7 can rotate freely around the rotating shaft 8. The end plate 9 is a circular flat plate with a diameter larger than that of the turntable 7. The end plate 9 is fixed coaxially with the turntable 7 to prevent the water pipe 1 from slipping off the side of the turntable 7 during the winding process. When the flushing spray mechanism moves, the water pipe 1 will stretch or contract with the movement of the slide 3. The water pipe winding mechanism can wind and release the water pipe 1 in an orderly manner, avoiding the water pipe 1 from being randomly distributed in the tunnel.

[0030] In the above structure, the water pipe winding mechanism effectively solves the problem of storing and extending the water pipe 1 during the movement of the flushing spray mechanism, making the arrangement of the water pipe 1 more neat and orderly, reducing the risk of the water pipe 1 being damaged by equipment or debris in the tunnel, which is conducive to extending the service life of the water pipe 1 and improving the safety and reliability of the entire spraying system.

[0031] In the specific structure of the water pipe winding mechanism, the water pipe winding mechanism also includes a pneumatic motor 10, the output end of the pneumatic motor 10 is connected to a motor reducer 11, and the output end of the motor reducer 11 is connected to the turntable 7 through a flexible transmission component.

[0032] In this embodiment, the pneumatic motor 10 serves as a power source and can be fixedly installed on the side wall of the tunnel or other locations. The motor reducer 11 reduces the output speed of the pneumatic motor 10 while increasing the output torque, enabling the turntable 7 to rotate smoothly and powerfully. The flexible transmission component can be a belt, chain, etc., which transmits the power of the motor reducer 11 to the turntable 7, causing the turntable 7 to rotate and realize the winding or unwinding of the water pipe 1. For example, when the flushing spray mechanism needs to move closer to the water pipe winding mechanism, the pneumatic motor 10 starts, and after being reduced in speed and increased in torque by the motor reducer 11, it drives the turntable 7 to rotate through the flexible transmission component. Since the rotation of the turntable 7 at this time will wind and retract the water pipe 1, the flushing spray mechanism moves closer to the water pipe winding mechanism. In addition, when the flushing spray mechanism needs to move away from the water pipe winding mechanism, the pneumatic motor 10 can also reverse, driving the turntable 7 to rotate in the opposite direction, releasing the water pipe 1 from the turntable 7, so as to meet the extension requirements of the water pipe 1 when the flushing spray mechanism moves, ensuring that the water pipe 1 can be wound and released in an orderly manner with the movement of the flushing spray mechanism during the entire operation of the spray system, avoiding the situation of messy winding or excessive stretching of the water pipe 1.

[0033] In the above structure, the pneumatic motor 10 and the motor reducer 11 work together to realize the winding action of the water pipe 1, thereby providing power for the water pipe winding mechanism and improving the working efficiency and automation of the water pipe winding mechanism.

[0034] Specifically, a first pulley 12 is mounted on the output end of the motor reducer 11, and a second pulley 13 is mounted on the outside of the bushing 8. The first pulley 12 and the second pulley 13 are connected by a transmission belt 14. In this embodiment, as... Figure 1 As shown, both the first pulley 12 and the second pulley 13 are circular pulleys, with the diameter of the first pulley 12 being smaller than that of the second pulley 13. The transmission belt 14 is a closed-loop structure, with its two ends respectively fitted around the outer circumference of the first pulley 12 and the second pulley 13. When the motor reducer 11 outputs power to drive the first pulley 12 to rotate, the first pulley 12 drives the second pulley 13 to rotate via the transmission belt 14, thereby causing the bushing 8 and the turntable 7 to rotate. This belt drive method has a simple structure, smooth transmission, and can effectively transmit power, while also buffering impacts and vibrations to a certain extent.

[0035] In the installation structure of track 2, track 2 is installed on the top of the roadway by a hanger 15. The slide 3 is U-shaped, and both sides of the slot of slide 3 are equipped with traveling wheels 16. The traveling wheels 16 on both sides of slide 3 respectively cooperate with the two sides of the upper surface of track 2.

[0036] In this embodiment, as Figure 3As shown, the boom 15 is a long strip structure, with one end fixed to the top of the tunnel and the other end connected to the track 2, allowing the track 2 to be securely installed on the tunnel top. The traveling wheels 16 are circular rollers, mounted on supports on both sides of the slide 3. The wheel surfaces of the traveling wheels 16 contact the track surfaces on both sides of the upper part of the track 2, and the traveling wheels 16 can roll freely on the track 2. This structural design allows the slide 3 to move on the track 2, reducing friction during movement and improving the stability of the slide 3.

[0037] In the above structure, the track 2 is installed on the top of the roadway by the hanger 15, which ensures the installation of the track 2 firmly and stably; the cooperation between the traveling wheels 16 on both sides of the slide 3 and the track 2 makes the flushing spray mechanism more stable during movement, which is conducive to improving the dust suppression effect of spraying, and also reduces the wear of the equipment during operation, extending the service life of the equipment.

[0038] The flushing spray mechanism includes a flushing spray rod 17 and a flushing spray head 18. The upper end of the flushing spray rod 17 is fixedly connected to the bottom of the slide block 3, and the lower end of the flushing spray rod 17 is fixedly connected to the flushing spray head 18. The flushing spray head 18 is connected to the water supply pipe 1.

[0039] In this embodiment, the flushing spray rod 17 is a straight rod structure, and its upper end can be fixed to the bottom of the slide block 3 by welding or bolting to ensure a firm and reliable connection. The flushing spray head 18 is installed at the lower end of the flushing spray rod 17, and its interior is equipped with an atomizing structure, which can atomize the water delivered by the water pipe 1 into fine water droplets and spray them out to achieve dust suppression in the roadway. For example, the flushing spray head 18 can be a centrifugal atomizing nozzle or a pressure atomizing nozzle, etc. In actual operation, the appropriate nozzle type can be selected according to the dust concentration and particle size in the roadway.

[0040] In the above structure, the water can be effectively converted into mist by the spray nozzle 18 and sprayed evenly in the tunnel, which improves the adsorption and settling effect of dust and thus better achieves the purpose of dust suppression in the tunnel.

[0041] In addition, at the positions below the top of the roadway corresponding to both ends of track 2, switching baffles I19 and II20 are respectively installed. Switching baffles I19 and II20 can be fixed to the inner wall of the roadway. A ball valve 21 is installed on the water supply pipe 1. The valve body of the ball valve 21 is fixedly connected to the flushing spray rod 17. The valve rod of the ball valve 21 includes rod body I22 and rod body II23. One end of rod body I22 is perpendicularly connected to one end of rod body II23. The other end of rod body I22 and the other end of rod body II23 can contact the switching baffles I19 and II20 respectively.

[0042] In this embodiment, the switching baffle I 19 and switching baffle II 20 are arc-shaped plate structures, fixedly installed at the lower ends of the track 2. The ball valve 21 is installed on the water supply pipe 1 near the flushing spray head 18, and the valve body of the ball valve 21 is fixedly connected to the flushing spray rod 17. When the slide 3 moves to one end of the track 2, for example, to the side near the switching baffle I 19, the rod I 22 will contact the switching baffle I 19. Under the action of the switching baffle I 19, the rod I 22 will drive the ball inside the ball valve 21 to rotate, causing the ball valve 21 to open and begin supplying water to the flushing spray head 18. When the slide 3 moves to the side near the switching baffle II 20, the rod II 23 will contact the switching baffle II 20. Under the action of the switching baffle II 20, the rod II 23 will drive the ball inside the ball valve 21 to rotate, causing the ball valve to close and stopping the supply of water to the flushing spray head 18.

[0043] In the above structure, by switching baffle I 19, switching baffle II 20 and ball valve 21, the water source can be shut off and the direction of movement can be changed in time when the flushing spray mechanism reaches both ends of the track 2, thus avoiding the waste of water resources.
