Description

Technical Field

[0001] This utility model belongs to the technical field of spray dust removal equipment, specifically relating to a spray dust removal equipment used in coal mines. Background Technology

[0002] Coal mining operations generate a large amount of coal dust during tunneling, loading, and transportation. If not controlled in time, this will increase the risk of occupational pneumoconiosis, and the accumulation of coal dust also poses a dust explosion hazard. Therefore, it is necessary to install spray dust suppression devices at designated locations in the roadways, using a spray to form a water curtain that covers the cross-section of the roadway. The water absorbs the airborne dust, thus blocking its passage. Most existing dust suppression equipment is fixed, and some structures suffer from cumbersome installation, poor stability, and fragility in terms of spray pipe deployment, positioning, and recovery, failing to meet the on-site requirements for flexible deployment and efficient dust suppression. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a spray dust removal device for coal mines. This device has high-efficiency dust removal capabilities and can be flexibly deployed in different working environments. The device can be quickly moved, deployed, and stored after being folded and stored as a whole. It has the advantages of strong mobility, wide spraying range, high dust removal efficiency, good structural reliability, and strong adaptability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spray dust suppression device for coal mining, comprising a mobile vehicle body, a telescopic support mechanism, an adjustable connecting assembly, and a folding spray pipe assembly, wherein the top of the mobile vehicle body is provided with a storage slot;

[0006] The adjustable connection assembly includes a sliding sleeve fixed to one end of the telescopic support arm, a sliding rod slidably installed on the inner side of the sliding sleeve, a set of first limiting plates at both ends of the sliding rod, a threaded hole through the inner and outer sides of the sliding sleeve and a first locking bolt threadedly installed thereon, and a clamp connected to one end of the sliding rod.

[0007] The folded spray pipe assembly includes a first spray pipe, a second spray pipe, and a third spray pipe. The first spray pipe is fixed inside the clamp. One end of the first spray pipe and the second spray pipe is provided with a first rotating connecting seat. The other end of the second spray pipe and one end of the third spray pipe are provided with a second rotating connecting seat. The first rotating connecting seat and the second rotating connecting seat are rotatably connected to each other.

The other end of the second spray pipe 42 and one end of the third spray pipe 43 are provided with a second rotating connecting seat 45. The first rotating connecting seat 44 and the second rotating connecting seat 45 are rotatably connected to each other.

[0046] This device not only possesses highly efficient dust removal capabilities, but also allows for rapid folding and relocation to new designated locations when changing dust removal deployment points. This enables flexible deployment in various operating environments. The entire device can be folded and stored for quick relocation, deployment, and storage. It boasts advantages such as high mobility, wide spraying range, high dust removal efficiency, good structural reliability, and strong adaptability. It is particularly suitable for large-area, high-density spray dust suppression operations in high-dust working areas such as coal mine faces, roadway intersections, and transfer points, demonstrating excellent practicality and promotional value.

[0047] One end of the mobile vehicle body 1 is provided with a booster pump receiving slot 12, and a door panel 13 is hinged to one end of the booster pump receiving slot 12. A booster pump 51 is installed inside the booster pump receiving slot 12, and a water supply hose 52 is connected to the water outlet end of the booster pump 51.

[0048] When the device is not in use, the water delivery hose 52 is stored in the booster pump receiving tank 12. When in use, one end of the water delivery hose 52 is connected to the water pipe connector 413 at one end of the first spray pipe 41. The booster pump 51 can be connected to the water source pipeline, pressurize the water in the water source pipeline and pump it into the water delivery hose 52, and deliver it to the first spray pipe 41.

[0049] One end of the mobile vehicle body 1 is connected to a towing frame 14.

[0050] The towing frame 14 can meet the needs of manual towing and can also be connected to some towing machinery underground, making it convenient for manual or mechanical movement and deployment.

[0051] Hydraulic support rods 15 are fixedly installed on both sides of the mobile vehicle body 1.

[0052] The hydraulic support rod 15 is used to extend when the device is parked and deployed. The hydraulic support rod 15 contacts the ground to support the device and stabilize its posture.

[0053] A transmission screw 25 is rotatably mounted on the inner side of the hollow support arm 23, and a first bevel gear 26 is sleeved on the outer side of the transmission screw 25. A rotating shaft 28 is rotatably mounted through the side of the hollow support arm 23. One end of the rotating shaft 28 is fixed to a second bevel gear 27, and the other end of the rotating shaft 28 is fixed to the output end of a second motor 29. The second motor 29 is fixed to the side of the hollow support arm 23.

[0054] The second motor 29 can drive the rotating shaft 28 to rotate, which in turn drives the second bevel gear 27 to mesh with the first bevel gear 26, thereby driving the transmission screw 25 to rotate. Through the threaded transmission between the transmission screw 25 and the telescopic support arm 24, the telescopic support arm 24 can be adjusted to extend or retract, thereby adjusting the height of the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43.

[0055] The bottom of the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 are all provided with support rods 46. A second limiting plate 47 is fixedly provided on the outside of the support rod 46. A racetrack-shaped reinforced slide 48 is connected between the support rod 46 at the bottom of the first spray pipe 41 and the support rod 46 at the bottom of the second spray pipe 42, and between the support rod 46 at the bottom of the second spray pipe 42 and the support rod 46 at the bottom of the third spray pipe 43. A second locking bolt 49 is threadedly connected to the bottom of the support rod 46.

[0056] The runway-shaped reinforced slide 48 is fixed to the outside of the support rod 46 by the cooperation of the second limiting plate 47 and the second locking bolt 49, so that the first spray pipe 41, the second spray pipe 42 and the third spray pipe 43 are effectively and stably supported, improving the stability and deformation resistance of the spray pipe assembly in the deployed state.

[0057] A relay hose 410 is connected between the first spray pipe 41 and the second spray pipe 42, and between the second spray pipe 42 and the third spray pipe 43.

[0058] The relay hose 410 can bend adaptively as the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 are folded, and is used to transport water flow between the first spray pipe 41, the second spray pipe 42, and the second spray pipe 42 and the third spray pipe 43.

[0059] One end of the third spray pipe 43 is provided with a plug 412, and one end of the first spray pipe 41 is connected to a water pipe connector 413.

[0060] The plug 412 is used to seal one end of the third spray pipe 43 to prevent water leakage, and the water pipe connector 413 is used to connect to the water supply hose 52 to access the water flow.

[0061] The bottom of the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 are all provided with atomizing nozzles 411 arranged evenly.

[0062] The atomizing nozzle 411 is used to atomize the water entering the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 and spray it out to form a continuous water curtain. At the same time, it ensures that the sprayed droplets are small in size and numerous, thereby improving the adsorption effect on dust.

[0063] The working principle and usage process of this utility model are as follows: In actual application, the operator first connects the mobile vehicle 1 to the traction point of the transportation equipment via the traction frame 14, and moves the device to the designated position in the coal mine operation area. The hydraulic support rods 15 set on both sides of the vehicle body provide ground support to ensure the stability of the vehicle body and prevent it from sliding. Then, the operator controls the first motor 22 to drive the hollow support arm 23 to rotate to the upright position via the bearing seat 21.

[0064] Then loosen the first locking bolt 34 and slide the slide rod 32 to adjust its position in the sliding sleeve 31, so that the clamp 35 and the folding spray pipe assembly 4 are away from the top of the moving vehicle body 1, and unfold the folding spray pipe assembly 4. When unfolding, loosen the second locking bolt 49 to release the fixation between the runway-shaped reinforced slide 48 and the second locking bolt 49 and the second limiting plate 47, thereby releasing the mutual locking between the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43. The first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 can then be unfolded through the first rotating connecting seat 44 and the second rotating connecting seat 45. After unfolding, tighten the bolt again. The second locking bolt 49 re-secures the runway-shaped reinforced slide 48 to the second locking bolt 49 and the second limiting plate 47, thereby re-locking the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 together. The runway-shaped reinforced slide 48 also reinforces and supports the connections between the first spray pipe 41 and the second spray pipe 42, as well as between the second spray pipe 42 and the third spray pipe 43. Then, the door panel 13 is opened, the water hose 52 is pulled out and connected to the water pipe connector 413, and the booster pump 51 is connected to the water source pipe. The extension height of the telescopic support arm 24 can then be controlled according to the height of the tunnel. Controlling the second motor 29 drives the rotating shaft 28 to rotate, which in turn drives the second bevel gear 27 to mesh with the first bevel gear 26, thereby driving the transmission screw 25 to rotate. Through the threaded transmission between the transmission screw 25 and the telescopic support arm 24, the telescopic support arm 24 is adjusted to extend or retract, thus adjusting the height of the first spray pipe 41, the second spray pipe 42, and the third spray pipe 43 so that they are close to the top wall of the tunnel. Then, the booster pump 51 can be started, and high-pressure water is delivered to the water pipe joint 413 on the first spray pipe 41 through the water delivery hose 52, and then transmitted to each section of the pipe in sequence through the relay hose. A plug 412 is installed at the end of the third spray pipe 43 to prevent backflow at the end of the water path. In addition to pressure relief, multiple atomizing nozzles 411 are installed below all pipe sections. High-pressure water flows through the atomizing nozzles and is sprayed into a fine mist, covering the coal dust diffusion area to achieve efficient dust removal. When changing the dust removal deployment point, the device can be quickly folded and transferred to the new designated deployment point, allowing for flexible deployment in different working environments. The equipment can be quickly moved, deployed, and stored after being folded and stored as a whole. It has the advantages of strong mobility, wide spray range, high dust removal efficiency, good structural reliability, and strong adaptability. It is especially suitable for large-area, high-density spray dust suppression operations in high-dust working areas such as coal mine faces, roadway intersections, and transfer points, and has good practicality and promotion value.
