Description

Technical Field

[0001] This invention relates to the field of tunnel construction equipment, and in particular to a self-moving dust collection and ventilation device for tunnel construction. Background Technology

[0002] Tunnel construction is a crucial step in urban underground space development and transportation infrastructure construction. However, it generates large amounts of high-concentration dust during drilling, blasting, excavation, and muck removal. This dust not only severely pollutes the working environment and affects the health of construction workers—long-term exposure can lead to occupational diseases such as pneumoconiosis—but also significantly reduces visibility within the tunnel, increases the safety risks of machinery operation, accelerates equipment wear, and impacts construction progress and project quality. Therefore, an efficient and reliable ventilation and dust removal system is essential for ensuring safe and environmentally friendly tunnel construction.

[0003] Currently, most dust collection and ventilation equipment used in tunnel construction is either fixed or simply mobile. Fixed equipment has limited installation location and airflow coverage, making it difficult to adapt to the continuous advancement of the tunnel face. Dust tends to accumulate and spread in areas far from the suction port. Although some equipment is equipped with a mobile base, its function is mainly focused on relocation, lacking the ability to effectively organize and dynamically adjust airflow patterns. Most existing equipment adopts a unidirectional suction or direct airflow design, resulting in a simple airflow organization method that makes it difficult to form a closed dust control field. Especially in tunnels with large cross-sections or complex ventilation requirements, dust easily escapes from the airflow boundary, leading to a decrease in collection efficiency.

[0004] On the other hand, the suction port direction, airflow speed, and effective range of existing dust collection equipment often cannot be flexibly adjusted according to on-site conditions. The size, distribution height, and diffusion characteristics of dust particles generated at different stages of tunnel construction vary, and traditional equipment lacks corresponding adaptive adjustment mechanisms, making it impossible to achieve precise dust collection and reducing the overall system's applicability and energy efficiency. Especially when dust concentration suddenly increases or the work surface changes, existing devices struggle to respond quickly, easily leading to uncontrolled dust.

[0005] Furthermore, during continuous dust collection, dust accumulates on the surfaces of filters, plates, or adsorption components, obstructing airflow, increasing resistance, reducing suction volume, and significantly decreasing efficiency. Although some equipment is equipped with cleaning mechanisms, such as mechanical rapping or pulse backflushing devices, the cleaning process often requires machine shutdown or is incomplete, making continuous, uninterrupted operation impossible. More importantly, if the removed dust is not promptly discharged from the collection area, it can easily cause secondary dust generation, creating internal circulation pollution and greatly weakening the system's actual dust removal effect. These defects of incomplete cleaning and asynchronous emissions severely restrict the reliability of long-term continuous operation.

[0006] The present invention aims to solve the technical problems existing in the prior art. To this end, a self-moving dust collection and ventilation device for tunnel construction is proposed. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] Example 1, please refer to Figure 1 , Figure 9 In this embodiment of the invention, a self-moving dust collection and ventilation device for tunnel construction includes a mobile installation platform 1, with a lifting installation plate 5 positioned directly above the mobile installation platform 1, and also includes a mobile module and an adjustable dust collection mechanism symmetrically arranged below the mobile installation platform 1.

[0038] The mobile module includes a mobile mounting frame 2, on which a plurality of drive rollers 45 are equally spaced. Spring mounting columns 44 are symmetrically arranged between the upper middle position of the mobile mounting frame 2 and the mobile mounting platform 1.

[0040] This equipment is placed in the tunnel construction area and can be moved and repositioned by driving the drive roller 45 or by connecting to an external traction device. During the movement, the shock absorption of the directional telescopic column 4 ensures that the adjustable dust collection mechanism on the equipment can operate stably.

[0041] At the same time, the height of the lifting installation plate 5 and its adjustable dust collection mechanism can be adjusted by driving the lifting column 3, so as to realize dust collection and ventilation operations at different heights.

[0042] Example 2, based on Example 1, please refer to... Figure 1 , Figure 2 , Figures 6-8 In this embodiment of the invention, the adjustable dust collection mechanism includes a bowl-shaped mounting cylinder 10, which is mounted on one end of the lifting mounting plate 5 via a folded fixing frame 9. A flow guiding mounting cylinder 19 is provided in the middle of the bowl-shaped mounting cylinder 10, a smooth conical cylinder cover 12 is provided on the outer side of the flow guiding mounting cylinder 19, and an annular arc cover 14 is provided at the bottom inner side of the bowl-shaped mounting cylinder 10. The annular arc cover 14 is connected to the smooth conical cylinder cover 12.

[0043] One end of the flow guiding installation cylinder 19 is flared, and the inner side of the flared end of the flow guiding installation cylinder 19 is connected to the bottom of the outer side of the bowl-shaped installation cylinder 10. A flow guiding drive component 41 is arranged directly opposite the bottom of the bowl-shaped installation cylinder 10. Several fixed installation posts 42 are arranged at equal angles on the outer side of the flow guiding drive component 41. The outer ends of the fixed installation posts 42 are all installed at the bottom of the bowl-shaped installation cylinder 10. A limit rotation post 37 is coaxially arranged on the end of the flow guiding drive component 41 facing the flow guiding installation cylinder 19 through a rotating shaft. The flared part of the flow guiding installation cylinder 19 A limiting mounting sleeve 20 is provided on the corresponding limiting rotating column 37. Several flow guiding mounting plates 21 are provided at equal angles on the outer side of the limiting mounting sleeve 20. The outer end of the flow guiding mounting plate 21 is connected to the flared inner wall of one end of the flow guiding mounting cylinder 19. A spiral flow guiding plate 38 is provided on the outer side of the limiting rotating column 37 inside the flow guiding mounting cylinder 19. The edge of the spiral flow guiding plate 38 is clearance-fitted with the inner wall of the flow guiding mounting cylinder 19. Several flow guiding fan blades 40 are provided at equal angles on the limiting rotating column 37 between the limiting mounting sleeve 20 and the flow guiding drive component 41.

[0044] An annular guide tube 25 is provided at the opening of the bowl-shaped mounting cylinder 10. Several atomizing nozzles 17 are provided on the annular guide tube 25 at equal angles to the annular arc-shaped cover 14 and the smooth conical cover 12. A buffer guide cavity 23 is provided inside the cylinder wall of the bowl-shaped mounting cylinder 10. The buffer guide cavity 23 is connected to the annular guide tube 25 through the infusion conduit 24. A booster pump 22 is provided at the bottom of the bowl-shaped mounting cylinder 10. One end of the booster pump 22 is connected to the buffer guide cavity 23, and the other end of the booster pump 22 is provided with a connecting conduit 11.

[0045] The outer end of the limiting rotating column 37 extends out of the flow guide mounting cylinder 19, and the outer end of the limiting rotating column 37 is coaxially provided with a limiting rotating shaft 43. The limiting rotating shaft 43 is axially aligned with a conical mounting column 33. One end of the conical mounting column 33 is fitted with a limiting bearing sleeve 34 in conjunction with the limiting rotating shaft 43. Several flow guide support plates 35 are provided at equal angles on the outer side of the limiting bearing sleeve 34. The other end edge of the conical mounting column 33 is provided with a reset rubber ring 32. An annular arc-shaped flow guide plate 13 is provided outward from the reset rubber ring 32.

[0046] When in the dust collection and ventilation working area, the connecting conduit 11 is connected to the external liquid supply equipment. At this time, the booster pump 22 is driven to pressurize the liquid and introduce it into the buffer guide chamber 23, and then introduce it into the annular guide tube 25 through the liquid delivery conduit 24. Then, the atomized droplets are sprayed out from the atomizing nozzle 17. The guide drive 41 is started, and the limit rotating column 37 is driven to rotate through the rotating shaft. At the same time as the limit rotating column 37 rotates, the guide fan blade 40 rotates, guiding the air and dust on the trumpet-shaped side of the guide installation tube 19 into the guide installation tube 19. At the same time, the spiral guide plate 38 is also rotating, capturing the air guiding the guide installation tube 19 and further accelerating it until the air is discharged at high speed from the other end of the guide installation tube 19.

[0047] The high-speed guided gas impacts the conical mounting column 33, and is guided towards the annular arc-shaped shield 14 through the inner side of the annular arc-shaped guide plate 13, and then flows over the surface of the smooth conical shield 12. At the same time, the atomizing nozzle 17 sprays atomized droplets towards the annular arc-shaped shield 14 and the smooth conical shield 12, so that it carries and adsorbs some of the dust in the guided air, and quickly adheres to the annular arc-shaped shield 14 and the smooth conical shield 12, thus completing the adsorption of some of the dust in the tunnel air.

[0048] The air flows further through the smooth conical hood 12. Part of it, along with the high-speed air introduced by the guide installation cylinder 19, re-enters the conical mounting column 33 and the annular arc-shaped guide plate 13, repeatedly entering the surfaces of the annular arc-shaped hood 14 and the smooth conical hood 12, and comes into contact with and is adsorbed by the atomized droplets. Another part of the air passing through the smooth conical hood 12 forms an annular swirling airflow between the high-speed airflow from the guide installation cylinder 19 and the air guided by the edge of the annular arc-shaped guide plate 13. The dust particles inside gradually merge into the high-speed airflow from the guide installation cylinder 19 and the air guided by the edge of the annular arc-shaped guide plate 13 under the centrifugal force of the swirling airflow, thereby improving the speed and quality of dust suppression.

[0049] Example 3, based on Example 1, please refer to... Figure 1 , Figures 3-5 In this embodiment of the invention, a limiting rotating frame 15 is provided on the outer side of the other end of the flow guiding installation cylinder 19, and a limiting rotating sleeve 18 is provided in cooperation with the limiting rotating frame 15. A plurality of steering drive guide wheels 16 are provided at equal angles on the limiting rotating frame 15, and the steering drive guide wheels 16 are all in contact with the inner wall of the limiting rotating sleeve 18. Limiting power supply rings 26 are symmetrically provided on both sides of the limiting rotating frame 15, and a limiting power supply groove 27 is provided on the inner side of the limiting rotating sleeve 18 in cooperation with the limiting power supply rings 26.

[0050] The outer side of the limiting rotating sleeve 18 is provided with a plurality of rotating scrapers 39 at equal angles, and the rotating scrapers 39 are all fitted to the annular arc surface cover 14 and the smooth conical cylindrical cover 12.

[0051] The upper end of the lifting mounting plate 5 is provided with an arc-shaped dust collection cylinder 7, and the bottom of the arc-shaped dust collection cylinder 7 extends out to provide a discharge pipe 6. The outer end of the discharge pipe 6 is rotatably provided with a discharge gate 8.

[0052] The steering drive guide wheel 16 is opened synchronously with the start of the equipment. Under the contact drive of the steering drive guide wheel 16, the limit rotating sleeve 18 is rotated. At this time, the rotating scraper 39 on it is in contact with the surface of the annular arc-shaped cover 14 and the smooth conical cylinder cover 12 to scrape off the dust and liquid mixture adsorbed on them. The scraped dust and liquid mixture clumps together and rolls down the rotating scraper 39 onto the arc-shaped dust collection cylinder 7. After a period of time, the discharge gate 8 is opened and poured out from the discharge pipe 6, or it is shoveled out directly from above the arc-shaped dust collection cylinder 7.

[0053] While the limiting rotating sleeve 18 and the limiting rotating frame 15 rotate together, the limiting power supply ring 26 and the limiting power supply groove 27 rotate and couple to supply power.

[0054] Example 4, based on Example 1, please refer to... Figure 6 , Figure 8 In this embodiment of the invention, the annular arc-shaped guide plate 13 is provided with a plurality of guide grooves 36 at equal angles on the side facing the bowl-shaped mounting cylinder 10, and the outer side of the conical mounting column 33 is also provided with a plurality of guide grooves 36 at equal angles.

[0055] The end of the conical mounting column 33 is provided with a spacing adjustment telescopic column 29, and the outer end of the spacing adjustment telescopic column 29 is provided with a spacing adjustment mounting plate 28. A plurality of swing mounting rods 30 are provided at equal angles on the outer side of the spacing adjustment mounting plate 28. One end of the swing mounting rod 30 is connected to the edge of the spacing adjustment mounting plate 28 through a steering shaft. The steering shaft is used to adjust the starting angle of the swing mounting rod 30. The other end of the swing mounting rod 30 is provided with a rubber top block 31.

[0056] The conical mounting post 33 and the guide groove 36 on the annular arc-shaped guide plate 13 reduce turbulence and ensure the directionality of airflow. At the same time, the telescopic adjustment of the spacing adjustment post 29 changes the spacing between the spacing adjustment mounting plate and the annular arc-shaped guide plate 13, thereby adjusting the force of the swing mounting rod 30 and its rubber top block 31 pressing the annular arc-shaped guide plate 13. In conjunction with the reset rubber ring 32, the curvature of the arc surface on the annular arc-shaped guide plate 13 is adjusted. According to the amount of dust in the air, the position of the airflow across the surface of the annular arc-shaped cover 14 and the smooth conical cover 12 is adjusted, that is, the distance and time of the airflow across the surface of the annular arc-shaped cover 14 and the smooth conical cover 12 are controlled. The return airflow is the airflow guided out by the annular arc-shaped guide plate 13.
