Description

Technical Field

[0001] This invention relates to the field of mine fire prevention and extinguishing technology, specifically to a long-distance conveying pneumatic resistance pump for mines. Background Technology

[0002] Spontaneous combustion of coal is one of the major natural disasters in my country's mines. In key state-owned coal mines, 56% of mines experience spontaneous combustion, and fires caused by spontaneous combustion account for over 90% of all mine fires. Inhibition pumps effectively suppress spontaneous combustion of residual coal by spraying inhibitors into areas such as coal faces, old mining areas, and goafs, protecting coal resources and reducing environmental pollution from fire accidents. Inhibition pumps can also be used as water vapor mist smoke and dust suppression equipment, spraying inhibitor mist into underground coal mines to effectively reduce dust concentration in the working area, improve underground air quality, protect miners' health, and reduce the environmental impact of dust emissions.

[0003] The mine-use pneumatic inhibitor pump uses compressed air as its power source and contains no electrical equipment. It is safe and reliable for underground use. However, it requires two people to work together: one person holds the nozzle and sprays it along the coal mine roadway, while the other person pushes the pump to follow, spraying as they move. While this method is flexible, it is highly dependent on the operator's skill. Inhibitor spraying requires the nozzle to sweep back and forth in a certain vertical direction to achieve large-area coverage of the coal face or loose coal surface. However, in actual operation, factors such as operator fatigue, distraction, and insufficient underground lighting can cause the sweeping amplitude to gradually decrease or deviate, especially over long periods. After continuous operation, arm fatigue causes the swing amplitude to decrease involuntarily, resulting in blind spots at the top and bottom of the spraying area. When operators try to speed up the operation, the swing amplitude may be too large, causing the inhibitor to spray out of the effective range. This uneven spraying caused by human factors directly affects the fire prevention and dust suppression effect of the inhibitor, creating a local spontaneous combustion hazard. Furthermore, if the spray gun is not turned off in time when the worker adjusts his posture, pauses, or changes direction, the inhibitor will continue to spray, resulting in overspraying in local areas. This not only wastes expensive inhibitor but may also cause the coal to become excessively wet. The excessively thick film on the coal surface will affect the normal penetration and curing effect of the inhibitor. Summary of the Invention

[0004] The purpose of this invention is to provide a long-distance conveying pneumatic resistance pump for mining, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a long-distance conveying pneumatic resistance pump for mining, comprising a vehicle body, a material cylinder fixedly installed on the top of the vehicle body, a pneumatic motor fixedly installed on the top of the material cylinder, an air pump fixedly installed on the bottom of the vehicle body, an installation plate fixedly connected to one side outer wall of the vehicle body, and a spray gun provided above the installation plate; The top of the mounting plate is provided with a stabilizing and flame-suppressing component, which includes two support plates fixedly connected to the top of the mounting plate.

The two support rods that are far apart are fixedly connected to a drive gear. The lower half of the inner wall of the two support plates is provided with a transverse reversing component. The spray gun swings at a limited angle through the transverse reversing component to uniformly cover and spray the coal mine surface. The spray gun is equipped with a stop-flow interruption component, which includes two sliding rods that are slidably disposed inside the support rod. The two sliding rods are respectively fixedly connected to an opening and closing block at their close ends. The spray gun is also fixedly connected to a spray pipe corresponding to the opening and closing block. The two sliding rods are respectively equipped with a swing separation component at their far ends. The spray gun sprays through the swing separation component to automatically interrupt the flow when it stops to prevent overspraying.

[0006] Preferably, the lateral commutation assembly includes: The lower half of the inner wall of the two support plates is rotatably connected to a rotating rod. Both ends of the rotating rod are fixedly connected to driven gears, and the top of the driven gear meshes with the bottom of the driving gear. The outer wall of the rotating rod is slidably connected to a sleeve, and the bottom outer wall of the sleeve is fixedly connected to a spring. The top of the mounting plate is fixedly connected to a base corresponding to the spring, and the bottom of the spring is fixedly connected to the top of the base.

[0007] Preferably, the bottom two outer walls of the sleeve are respectively fixedly connected with locking rods, and the ends of the two locking rods that are far apart pass through the inner walls of the two support plates respectively. The locking rods form an elastic transverse movement mechanism with the sleeve and spring. One end of one of the locking rods is pressed and set on one end face of one of the driven gears by the spring.

[0008] Preferably, the two driven gears are fixedly connected at equal distances to the corresponding locking rods at their close end faces with inclined locking teeth, and the two driven gears are fixedly connected to the close end faces with mounting rings, and one end of the mounting rings is provided with a reversing inclined groove corresponding to the locking rods.

[0009] Preferably, the swing separation assembly includes: Two support rods have sliding grooves at their near ends, with the outer wall of the rod sliding against the inner wall of the groove. Two springs are fixedly connected to the far ends of the two rods, and the far ends of the two springs are fixedly connected to the inner wall of the groove. A limit groove is formed on the top outer wall of the support rod corresponding to the groove. A fixing rod is fixedly connected to the outer wall of the far ends of the two rods, and the outer wall of the fixing rod is slidably connected to the inner wall of the limit groove.

[0010] Preferably, mounting cylinders are fixedly connected to the outer walls of the two support plates on their adjacent sides, corresponding to the fixing rods. The inner wall of the mounting cylinder is sleeved on the outer wall of the support rod. Unlocking blocks are fixedly connected to the inner walls of the mounting cylinders at equal distances from the fixing rods, and the outer walls of the unlocking blocks on both sides are inclined.

[0011] Preferably, the material cylinder is equipped with a stirring assembly inside, the output end of the pneumatic motor is connected to the stirring assembly, the top of the material cylinder is provided with a feed port, the delivery end of the air pump is fixedly connected to a delivery hose, and the other end of the delivery hose is connected to the input end of the spray gun, the output end of the spray gun is provided with a spray hole, and the inner wall of the spray hole is provided with a sealing and dustproof component.

[0012] Preferably, the sealing dustproof component includes two connecting rods respectively hinged to the outer wall of the two opening and closing blocks on the side facing the nozzle, and the other end of the two connecting rods is hinged to a sealing block, and the outer diameter of the sealing block matches the inner diameter of the nozzle, and the end of the sealing block facing the opening and closing block is frustoconical.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When spraying inhibitors in underground coal mines, the horizontal directional switching component can limit the vertical swing range of the spray gun during the operator's control of the spray gun movement. Each switching requires moving to the maximum swing angle before unlocking the reverse movement, and it can prevent backing out during the movement, thus setting a boundary for the swing amplitude. The operator cannot continue swinging beyond the limit point, nor can they retreat prematurely before completing the spraying in the current direction. This mechanically ensures that the amplitude of each swing is complete and the boundary is consistent, so that the spraying area completely covers the target coal wall in the vertical direction, without missing the top and bottom, thereby ensuring the fire-retardant ability of the inhibitor in the coal mine.

[0014] 2. When spraying inhibitors in underground coal mines, the system can separate the two opening and closing blocks during the swinging process to release the blockage on the nozzle, allowing the inhibitor liquid to be sprayed out normally. If the swinging process stops unexpectedly, the two opening and closing blocks can be merged by the second spring to cut off the flow of inhibitor liquid in time. This forcibly binds the spraying behavior of the spray gun with the swinging action. The spraying automatically starts when the spray gun starts swinging and automatically stops when the swinging stops, ensuring that liquid is only sprayed during the swinging motion. This prevents excessive spraying at fixed points and eliminates overspraying caused by human factors, thus ensuring the uniformity of the inhibitor liquid covering the coal mine during the spraying process and improving the fire prevention and flame retardant ability of the inhibitor for the coal mine.

[0015] 3. When spraying inhibitor on underground coal mines, through the cooperation of the connecting rod and the plugging block, when the spraying stops, such as when replacing or adding inhibitor liquid, when the opening and closing blocks are combined, the plugging block located in the spray gun can be synchronously driven to move to block the spray holes of the spray gun, physically isolating the spray holes from the roadway environment, preventing suspended coal dust from entering and polluting the internal channels of the spray holes and the residual inhibitor liquid. At the same time, the spray holes can be cleaned to keep them unobstructed, ensuring the spraying quality after multiple replacements of inhibitor liquid during long-distance operations, which is conducive to enhancing the fire and flame retardant ability of the inhibitor for coal mines.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figures 1-8 The present invention provides a long-distance conveying pneumatic resistance pump for mining, including a vehicle body 1, a material cylinder 2 fixedly installed on the top of the vehicle body 1, a pneumatic motor 3 fixedly installed on the top of the material cylinder 2, an air pump 4 fixedly installed on the bottom of the vehicle body 1, an mounting plate 5 fixedly connected to one side of the outer wall of the vehicle body 1, and a spray gun 6 provided above the mounting plate 5.

[0020] The material cylinder 2 is equipped with a stirring assembly. The output end of the pneumatic motor 3 is connected to the stirring assembly. The top of the material cylinder 2 is provided with a feed port. The conveying end of the air pump 4 is fixedly connected to a conveying hose 10, and the other end of the conveying hose 10 is connected to the input end of the spray gun 6. The output end of the spray gun 6 is provided with a spray hole 11.

[0021] In this embodiment, when using the pneumatic inhibition pump in the mine, the vehicle body 1 is first pushed to the starting position of the underground roadway. Then, the inhibition agent particles and water are poured into the material cylinder 2 through the feed port. The pneumatic motor 3 drives the stirring component to mix and stir the materials. After the stirring is completed, the air pump 4 sends the inhibition agent liquid in the material cylinder 2 into the spray gun 6 through the delivery hose 10. Then, the operator can carry out the spraying operation in the roadway coal mine while walking through the spray gun 6.

[0022] Furthermore, a stabilizing and flame-suppressing component 7 is provided on the top of the mounting plate 5. The stabilizing and flame-suppressing component 7 includes two support plates 701 fixedly connected to the top of the mounting plate 5. Two support rods 702 are rotatably connected to the upper inner walls of the two support plates 701 respectively. The outer walls of the two support rods 702 that are close to each other are fixedly connected to the inner wall of the spray gun 6. The two support rods 702 that are far apart are fixedly connected to the drive gears 703 respectively. A transverse reversing assembly is provided on the lower inner walls of the two support plates 701.

[0023] During the spraying process, two support rods 702 are rotatably connected to the upper inner walls of the two support plates 701. The outer walls of the two support rods 702 that are close to each other are fixedly connected to the inner wall of the spray gun 6, thereby supporting the spray gun 6. The operator can hold the handle on the spray gun 6 and drive the spray gun 6 to swing up and down and move in coordination to achieve uniform spraying.

[0024] To ensure uniform spraying of the inhibitor and prevent inadequate fire prevention and flame retardancy, during the swinging of the spray gun 6, two drive gears 703 are fixedly connected to the far ends of two support rods 702. The lower half of the inner wall of the two support plates 701 is equipped with a transverse reversing component. The transverse reversing component limits the vertical swing range of the spray gun 6. Each reversal requires moving to the maximum swing angle before unlocking the reverse movement, and it can prevent backing up during the movement. This sets a boundary for the swing amplitude, preventing the operator from continuing to swing beyond the limit point or backing up before completing the current direction of spraying. This mechanically ensures that the amplitude of each swing is complete and the boundary is consistent, so that the spraying area completely covers the target coal wall in the vertical direction, with no omissions at the top and bottom, thus ensuring the fire prevention and flame retardancy of the inhibitor in the coal mine.

[0025] Furthermore, the lateral commutation component includes: The lower half of the inner wall of the two support plates 701 is rotatably connected to the rotating rod 704. The two ends of the rotating rod 704 are respectively fixedly connected to the driven gear 705, and the top of the driven gear 705 meshes with the bottom of the driving gear 703 for transmission. The outer wall of the rotating rod 704 is slidably connected to the sleeve 706, and the bottom outer wall of the sleeve 706 is fixedly connected to the spring 707. The top of the mounting plate 5 is fixedly connected to the base 708 corresponding to the spring 707, and the bottom of the spring 707 is fixedly connected to the top of the base 708.

[0026] Specifically, two support rods 702 are fixedly connected to opposite ends of a drive gear 703, which can synchronously drive the two drive gears 703 to rotate when the spray gun 6 swings up and down. Then, the top of the driven gear 705 meshes with the bottom of the drive gear 703, so that the drive gear 703 can synchronously drive the driven gear 705 to rotate. Next, a sleeve 706 is slidably connected to the outer wall of the rotating rod 704, and a spring 707 is fixedly connected to the outer wall of the bottom center of the sleeve 706. The top of the mounting plate 5 is fixedly connected to the base 708 corresponding to the spring 707, and the bottom of the spring 707 is fixedly connected to the top of the base 708. Under normal circumstances, the sleeve 706 will slide to the left or right side of the rotating rod 704 under the elastic force of the spring 707.

[0027] Furthermore, two locking rods 709 are fixedly connected to the outer walls of the bottom sides of the sleeve 706. The ends of the two locking rods 709 that are far apart pass through the inner walls of the two support plates 701 respectively. The locking rods 709 form an elastic transverse movement mechanism with the spring 707 through the sleeve 706. One end of one locking rod 709 is pressed and set on one end face of one driven gear 705 by the spring 707.

[0028] Two driven gears 705 are fixedly connected at equal distances to one end face of the corresponding locking rod 709 with inclined locking teeth 710. An installation ring 711 is fixedly connected to one end face of the two driven gears 705, and a reversing inclined groove 712 is opened at one end of the installation ring 711 corresponding to the locking rod 709.

[0029] Specifically, the lever 709, through the sleeve 706 and spring 707, forms an elastic lateral movement mechanism. One end of the lever 709 is pressed against one end face of one driven gear 705 by the spring 707. The two driven gears 705 have equidistant inclined teeth 710 fixedly connected to their respective end faces. When the lever 709 swings normally upwards or downwards, one end of the lever 709 slides relative to one end face of a driven gear 705, and can slide back slightly under the guidance of the inclined teeth 710, thus passing over several inclined teeth 710 on the surface of the driven gear 705. However, when moving in the opposite direction, it is limited by the flat surface on the other side of the inclined teeth 710 and cannot slide back, thus achieving unidirectional swinging. A mounting ring 711 is fixedly connected to one of the adjacent end faces, and a reversing groove 712 is opened at one end of the mounting ring 711 corresponding to the locking rod 709. When the swing reaches the maximum angle, one end of the locking rod 709 will slide over the last inclined locking tooth 710 and onto the reversing groove 712. Under its guidance, it will slide back significantly. The distance of movement at this time will cause the sleeve 706 to slide to the other side of the rotating rod 704 under the elastic force of the spring 707. At this time, the locking rod 709 will disengage from the current driven gear 705. At this time, the other locking rod 709 will be pressed against the surface of the other driven gear 705 under the movement of the sleeve 706. This unlocks the swing in the other direction, so that the reversing can be unlocked when the swing reaches the maximum angle, forming a cyclic swing, ensuring that the amplitude of each swing is complete and the boundary is consistent.

[0030] Example 2: Based on the above examples, the spray gun 6 is equipped with a stop-flow interruption component 8 inside; Furthermore, the stop-flow interruption component 8 includes two slide rods 801 that are slidably disposed inside the support rod 702. The ends of the two slide rods 801 that are close to each other are respectively fixedly connected to opening and closing blocks 803. The spray gun 6 is fixedly connected to a nozzle 804 corresponding to the opening and closing blocks 803. The ends of the two slide rods 801 that are far apart are respectively provided with swing separation components. The spray gun 6 sprays through the swing separation components to automatically interrupt the flow when the stop is made to prevent overspraying.

[0031] In this embodiment, two sliding rods 801 are respectively fixedly connected to opening and closing blocks 803 at their close ends. A spray pipe 804 is fixedly connected to the inside of the spray gun 6 corresponding to the opening and closing blocks 803. Two sliding rods 801 are respectively provided with swing separation components at their far ends. This allows the two opening and closing blocks 803 to release the blockage of the spray pipe 804 during the swinging process, so that the inhibitor liquid can be sprayed out normally. When the swinging stops unexpectedly, the flow of inhibitor liquid is cut off in time, so that the spraying behavior of the spray gun 6 is forcibly bound to the swinging action. The spray gun 6 automatically starts spraying when it starts swinging and automatically stops spraying when it stops swinging, ensuring that liquid is only sprayed during the swinging motion, preventing excessive spraying at fixed points, eliminating overspraying caused by human factors, and thus ensuring the uniformity of the inhibitor liquid covering the coal mine during the spraying process, which is beneficial to improving the fire prevention and flame retardant ability of the inhibitor for the coal mine.

[0032] Furthermore, the swing separation assembly includes: Two support rods 702 have sliding grooves 802 at their near ends. The outer wall of the slide rod 801 slides against the inner wall of the sliding groove 802. The two slide rods 801 are respectively fixedly connected to the opposite ends of the two slide rods 801. The opposite ends of the two springs 805 are respectively fixedly connected to the inner wall of the sliding groove 802. The top outer wall of the support rod 702 is provided with a limiting groove 806 corresponding to the sliding groove 802. The outer walls of the opposite ends of the two slide rods 801 are respectively fixedly connected to a fixing rod 807, and the outer wall of the fixing rod 807 slides against the inner wall of the limiting groove 806.

[0033] The outer walls of the two support plates 701 that are close to each other are respectively fixedly connected to the fixing rods 807 with mounting cylinders 808, and the inner wall of the mounting cylinder 808 is sleeved on the outer wall of the support rod 702. The inner wall of the mounting cylinder 808 is fixedly connected to the fixing rods 807 at equal distances with unlocking blocks 809, and the outer walls on both sides of the unlocking block 809 are inclined.

[0034] Specifically, under normal circumstances, the two support rods 702 have sliding grooves 802 at their approaching ends, allowing the outer wall of the slide rod 801 to slide against the inner wall of the groove 802. The two slide rods 801 have springs 805 fixedly connected to their distant ends, and the distant ends of the two springs 805 are fixedly connected to the inner wall of the groove 802. This allows the spring force of the springs 805 to cause the two slide rods 801 to move the opening and closing block 803 to close and block the nozzle 804. When swinging, a limit groove 806 is formed on the top outer wall of the support rod 702 corresponding to the groove 802. A fixing rod 807 is fixedly connected to the outer wall of the two slide rods 801 at their distant ends. The outer wall of rod 807 is slidably connected to the inner wall of limiting groove 806. The inner wall of mounting cylinder 808 is sleeved on the outer wall of support rod 702. Unlocking blocks 809 are fixedly connected at equal distances to the inner wall of mounting cylinder 808 corresponding to fixed rod 807. The outer walls on both sides of unlocking block 809 are inclined. When spray gun 6 swings up and down, the support rod 702 will drive the fixed rod 807 to move in a circle. At this time, the fixed rod 807 will contact the inclined surfaces of several unlocking blocks 809, causing the two sliding rods 801 to be squeezed and separated. They will remain separated in the continuous up and down swinging state. So when the swing stops unexpectedly, the spring 805 can drive the two opening and closing blocks 803 to merge, and the flow of inhibitor liquid can be cut off in time.

[0035] In Example 3, based on the above examples, a sealing and dustproof component 9 is provided on the inner wall of the nozzle 11; Furthermore, the sealing and dustproof component 9 includes two connecting rods 901 respectively hinged to the outer wall of the two opening and closing blocks 803 on the side facing the nozzle 11. The other ends of the two connecting rods 901 are jointly hinged to a sealing block 902, and the outer diameter of the sealing block 902 matches the inner diameter of the nozzle 11. The end of the sealing block 902 facing the opening and closing block 803 is frustoconical.

[0036] In this embodiment, the connecting rod 901 and the sealing block 902 work together so that when spraying stops, such as when replacing the inhibitor liquid, the sealing block 902 located inside the spray gun 6 can move synchronously when the opening and closing block 803 closes to seal the spray hole 11 of the spray gun 6, physically isolating the spray hole 11 from the roadway environment, preventing suspended coal dust from entering and contaminating the internal channel and residual inhibitor liquid of the spray hole 11, and cleaning the spray hole 11 to keep it unobstructed. This ensures the spraying quality after multiple replacements of the inhibitor liquid during long-distance operations, thereby improving the fire-retardant ability of the inhibitor for coal mines. Furthermore, since the sealing block 902 is truncated cone-shaped at one end facing the opening and closing block 803, the impact force of the inhibitor liquid on the opening and closing block 803 during spraying can be reduced, thus reducing the separation resistance of the slide rod 801 during spraying.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
