Technical Field

[0001] The present invention relates to the field of ventilation and dust removal for tunnel construction, and particularly to a ventilation and dust removal device for tunnel construction. Background Technique

[0002] A tunnel refers to an engineering structure buried in the stratum, which is a form of human utilization of underground space. Tunnels can be classified into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels according to their uses; they can be classified into soil tunnels and rock tunnels according to the geological conditions they are in; they can be classified into short tunnels, medium-long tunnels, long tunnels, and extra-long tunnels according to their lengths; they can be classified into mountain tunnels, underwater tunnels, and urban tunnels according to their locations; and they can be classified into shallow-buried tunnels and deep-buried tunnels according to the burial depth. The structure of a tunnel includes two parts: the main building and the auxiliary equipment. The main building consists of the tunnel body and the portal.

[0003] During tunnel construction, a large amount of dust is generated, which will affect the construction workers, resulting in a reduction in construction efficiency. Moreover, when cleaning the dust, most of it is cleaned manually, which not only reduces the efficiency but also increases the construction cost.

[0019] Compared with the prior art, the present invention provides a ventilation and dust removal device for tunnel construction, which has the following beneficial effects:

[0020] 1. For the ventilation and dust removal device for tunnel construction, by starting the provided servo motor, the first exhaust fan, the first scraper, and the second scraper can be driven through the first rotating shaft. When the first exhaust fan rotates, the dust inside the tunnel can be absorbed and processed by the first dust removal assembly. At the same time, the filter plate will filter it, so that the large-volume sundries drawn into the inner cavity of the first dust removal assembly in the tunnel will remain in the inner cavity of the first dust removal assembly, and the remaining fine dust will remain at the other end of the inner cavity of the first dust removal assembly. After removing the filter plate, it can be cleaned. When the first scraper and the second scraper rotate, they will simultaneously clean the outer wall of the filter plate and the inner wall of the first dust removal assembly, and can scrape off the dust and sundries accumulated on the inner wall of the first dust removal assembly and the outer wall of the filter plate, thereby avoiding blockage of the filter plate and at the same time having a certain cleaning effect on the first dust removal assembly.

[0021] 2. For the ventilation and dust removal device used in tunnel construction, when the first rotating shaft rotates, it will drive the pulley on its outer wall to rotate simultaneously. At this time, the second exhaust fan can be driven to rotate through the belt and the pulley on the other side. At this time, the second exhaust fan can collect and process the dust accumulated on the ground in the tunnel, so that it can be collected into the inner cavity of the first collection box. When the first rotating shaft rotates, it will drive the bevel gear on its outer wall to rotate. At this time, the bevel gear at the top of the first connecting shaft can mesh with it, so as to drive the gear to rotate through the first connecting shaft. The gear can mesh with the gear ring at this time, and at the same time drive the third exhaust fan and the brush. Through the set brush, the ground in the tunnel can be cleaned, and the dust and sundries at the cleaning position can be swept to both sides, which is also convenient for the first collection box to collect them. When carrying out the dust removal work in the tunnel, the dust in the tunnel and at the bottom of the tunnel can be collected at the same time, so as to effectively improve the dust removal efficiency of the tunnel.

[0022] 3. For the ventilation and dust removal device used in tunnel construction, when the third exhaust fan rotates, the dust and sundries remaining in the inner cavity of the first dust removal component can be sucked into the inner cavity of the dust trough. Through the set dust trough, with the cooperation of the first scraper and the second scraper, the scraped dust can be collected into the inner cavity of the second collection box, which is convenient for unified cleaning.

[0023] 4. For the ventilation and dust removal device used in tunnel construction, by starting the set hydraulic lifting rod, the height of the second dust removal component can be adjusted. By starting the set rotating motor, the angle of the second dust removal component can be adjusted through the telescopic rod, so that the second dust removal component can be adjusted to an appropriate height to carry out dust removal work on the top inside the tunnel. And through the set telescopic rod, the second dust removal component can be supported. By starting the set vibration motor, the second dust removal component can be driven to vibrate, and with the cooperation of the set brush roller, the top of the tunnel can be cleaned, and the dust accumulated on its top can be swept off.

[0024] 5. For the ventilation and dust removal device used in tunnel construction, through the set groove, the dust falling into its inner cavity can be discharged to the bottom of the second dust removal component. Through the opened through groove, the swept dust can be collected into the inner cavity of the first dust removal component. Through the rack arranged in the inner cavity of the groove, when the brush roller rotates in the inner cavity of the groove, the rack can contact with it, so as to have a certain cleaning effect on the brush roller, and thus improve the working efficiency of the brush roller.

[0025] 6. The ventilation and dust removal device for tunnel construction can, through the provided water delivery pipe, input the water in the inner cavity of the water tank into the return pipe, enabling the return pipe to supply water to the atomizing nozzles. When dust removal work is carried out in the tunnel, it can perform dust suppression on the residual dust inside, thereby preventing a large amount of dust from spreading in the inner cavity of the tunnel and facilitating the normal work of the staff in the tunnel. Through the provided spring, the shielding component can be contracted at all times. When the shielding component moves to the top of the atomizing nozzle, it can shield the atomizing nozzle. When it is idle, it can protect the atomizing nozzle to prevent blockage and damage due to long-term idleness. After moving the movable rod to the outside of the return pipe, the shielding component can be disengaged from the top of the atomizing nozzle, and thus the atomizing nozzle can be used normally for dust suppression work.

[0026] 7. The ventilation and dust removal device for tunnel construction can, through the provided cleaning component, clean the ground inside the tunnel, push the dust and debris accumulated on the ground in the moving direction of the vehicle body. When the vehicle body completes the dust removal work in the tunnel, the cleaning component can also collect the debris accumulated at the bottom of the tunnel, facilitating unified cleaning. Moreover, the installation groove provided in the cleaning component can install a rag. After the atomizing nozzles perform dust suppression work, the cleaning component can clean the tunnel through the installed rag, which can further improve the cleaning efficiency.

[0027] 8. The ventilation and dust removal device for tunnel construction can, through the provided torsion rotating shaft, enable the cleaning component to always rotate inside the vehicle body. By rotating the provided rotating handle, the bidirectional lead screw can be driven to rotate, enabling the top of the support column to be threadedly connected to the bidirectional lead screw. At this time, the support column can move left and right. When the support column moves to the outside of the vehicle body, the cleaning component can be unfolded, which can adapt to the tunnel size and at the same time increase the cleaning range of the cleaning component. When the support column moves to the inside of the vehicle body, the cleaning range of the cleaning component can be reduced and it can be retracted. BRIEF DESCRIPTION OF THE DRAWINGS

At the bottom of the third exhaust fan 16, a brush 17 is provided. At the top of the outer wall of the first dust removal component 2, a through groove 3 is opened. At the bottom of the inner cavity of the first dust removal component 2, a dust groove 4 is opened. The dust groove 4 communicates with the inner cavity of the second collection box 15. Inside the inner cavities of the second collection box 15 and the first collection boxes 11, filter meshes 12 are installed. At one end of the first dust removal component 2 away from the filter plate 5, a servo motor 7 is installed. The servo motor 7 is installed with a first rotating shaft through a coupling.

The first rotating shaft is rotatably connected to the center of the inner cavity of the filter plate 5 and installed on the outer wall of the first scraper 13. The outer wall of the second scraper 14 is attached to the inner wall of the first dust removal component 2. The first scraper 13 is attached to the outer wall of the filter plate 5. At one end of the two first collection boxes 11, second exhaust fans 10 are symmetrically installed. At the end of the second exhaust fan 10 away from the first collection box 11, a belt 9 is provided. At both ends of the inner cavity of the belt 9, belt pulleys 8 are installed. One side belt pulley 8 is installed on the outer wall of the second exhaust fan 10 and used to drive the second exhaust fan 10. The other side belt pulley 8 is installed on the outer wall of the first rotating shaft. At the top of the brush 17, a second connecting shaft 22 is installed.

[0039] By starting the servo motor 7 set, the first exhaust fan 6, the first scraper 13, and the second scraper 14 can be driven through the first rotating shaft. When the first exhaust fan 6 rotates, the first dust removal component 2 can absorb and process the dust inside the tunnel. At the same time, the filter plate 5 will filter it, so that the large-volume sundries drawn into the inner cavity of the first dust removal component 2 in the tunnel will remain in the inner cavity of the first dust removal component 2, and the remaining fine dust will remain at the other end of the inner cavity of the first dust removal component 2. After removing the filter plate 5, it can be cleaned.

[0040] When the first rotating shaft rotates, it will simultaneously drive the pulley 8 on its outer wall to rotate. At this time, the second exhaust fan 10 can be driven to rotate through the belt 9 and the pulley 8 on the other side. At this time, the second exhaust fan 10 can collect and process the dust accumulated on the ground in the tunnel, so that it can be collected into the inner cavity of the first collection box 11. When the first rotating shaft rotates, it will drive the bevel gear 20 on its outer wall to rotate. At this time, the bevel gear 20 at the top of the first connecting shaft 19 can mesh with it, so as to drive the gear 18 to rotate through the first connecting shaft 19.

When performing the dust removal work in the tunnel, the dust inside the tunnel and at the bottom of the tunnel can be collected simultaneously, thereby effectively improving the dust removal efficiency of the tunnel;

[0041] When the third exhaust fan 16 rotates, the dust and sundries remaining in the inner cavity of the first dust removal component 2 can be drawn into the inner cavity of the dust tank 4.

One end of the spring 38 is installed in the inner cavity of the movable groove 37, and the other end of the spring 38 is installed on the side of the shielding component 35. There are two cleaning components 39. On the opposite sides of the tops of the two cleaning components 39, torsion rotating shafts 43 are symmetrically installed. The torsion rotating shafts 43 are installed in the inner cavity of the vehicle body 1. The top of the support column 42 is movably connected to the top of the inner cavity of the vehicle body 1. In the top of the inner cavity of the vehicle body 1, a bidirectional lead screw 41 is rotatably connected. On the side of the bidirectional lead screw 41, a turning handle 40 is installed. The turning handle 40 is rotatably connected to the side of the vehicle body 1. The top of the support column 42 is threadedly connected to the outer wall of the bidirectional lead screw 41. In the bottom of the inner cavity of the cleaning component 39, an installation groove is provided;

[0048] By setting the water delivery pipe 32, the water in the inner cavity of the water tank 31 can be input into the return pipe 33, so that the return pipe 33 can supply water to the atomizing nozzle 34. When dust removal work is carried out in the tunnel, the residual dust inside can be dusted, so as to avoid more dust floating in the inner cavity of the tunnel and facilitate the normal work of the staff in the tunnel. By setting the spring 38, the shielding component 35 can be contracted at all times. When the shielding component 35 moves to the top of the atomizing nozzle 34, it can shield the atomizing nozzle 34. When it is idle, it can protect the atomizing nozzle 34 to avoid the phenomenon of blockage and damage due to long-term idleness. After moving the movable rod 36 to the outside of the return pipe 33, the shielding component 35 can be separated from the top of the atomizing nozzle 34, so that the atomizing nozzle 34 can be normally used for dusting work;

[0049] Through the provided cleaning component 39, the ground inside the tunnel can be cleaned. Dust and debris accumulated on the ground can be pushed in the moving direction of the vehicle body 1.

[0050] Through the provided torsion rotating shaft 43, the cleaning component 39 can always rotate the inner side of the vehicle body 1. By rotating the provided rotating handle 40, the bidirectional lead screw 41 can be driven to rotate, enabling the top of the support column 42 to be threadedly connected to the bidirectional lead screw 41. At this time, the support column 42 can move left and right. When the support column 42 moves outward from the vehicle body 1, the cleaning component 39 can be unfolded, which can adapt to the tunnel size and also increase the cleaning range of the cleaning component 39. When the support column 42 moves inward from the vehicle body 1, the cleaning range of the cleaning component 39 can be reduced and it can be retracted.

[0051] It should be noted that the present invention is a ventilation and dust removal device for tunnel construction. During use, the vehicle body 1 is pushed into the tunnel. Water is injected into the inner cavity of the water tank 31, and the hydraulic lifting rod 26 is started to adjust the height of the second dust removal component 23 until the brush roller 28 fits against the top of the tunnel. Install the rag at the cleaning component 39 according to the usage requirements, adjust the positions of the two cleaning components 39 according to the tunnel size, rotate the rotating handle 40 to drive the bidirectional lead screw 41 to rotate, enabling the top of the support column 42 to be threadedly connected thereto. The support column 42 can then move. After the support column 42 contacts the cleaning component 39, it can drive the cleaning component 39 to unfold until it reaches a suitable size;

[0052] Start the vibration motor 24 and the servo motor 7. After the vibration motor 24 is started, it drives the brush roller 28 to vibrate through the second dust removal component 23. At the same time, start the rotating motor 27, enabling the telescopic rod 25 to drive the second dust removal component 23 to rotate. At this time, the brush roller 28 can perform the dust removal work on the top of the tunnel and can sweep off the dust accumulated on its top;

[0053] After starting the servo motor 7, it will drive the first extraction fan 6, the first scraper 13, the pulley 8 and the belt 9. When the first extraction fan 6 rotates, it will suck the dust in the tunnel into the inner cavity of the first dust removal component 2. At the same time, the dust swept by the second dust removal component 23 will be sucked into the inner cavity of the first dust removal component 2 through the through groove 3. After being filtered by the filter plate 5, part of the large-volume dust and sundries will remain in the inner cavity of the first dust removal component 2. After the first scraper 13 rotates, it will drive the second scraper 14 to rotate. At this time, the sundries and dust on the outer wall of the filter plate 5 and the inner wall of the first dust removal component 2 can be scraped off. Part of the scraped dust will be scraped into the inner cavity of the dust slot 4 and fall into the inner cavity of the second collection box 15;

[0054] When the servo motor 7 starts, it will drive the bevel gear 20 at the top to rotate at the same time. At this time, the bevel gear 20 at the top can be engaged with the bevel gear 20 at the top of the first connecting shaft 19, so as to drive the gear 18 to be engaged with the gear ring 21. At this time, the third extraction fan 16 and the brush 17 can be driven. The third extraction fan 16 can suck the dust remaining in the inner cavity of the first dust removal component 2 into the inner cavity of the second collection box 15 at this time. When the brush 17 rotates, it will clean the ground of the tunnel, so that the dust and sundries on the ground will float to both sides. At this time, the second extraction fan 10 driven by the pulley 8 and the belt 9 can suck the dust on the ground into the inner cavity of the first collection box 11 for storage;

[0055] Inject the water in the inner cavity of the water tank 31 into the atomizing nozzle 34 through the water delivery pipe 32. Disengage the shielding component 35 from the top of the atomizing nozzle 34 and start the atomizing nozzle 34. At this time, the tunnel interior can be sprayed for dust reduction treatment. When the vehicle body 1 moves, the cleaning component 39 at its bottom cooperates with the rag to clean the bottom of the tunnel, and at the same time, it will push the large-volume sundries forward, which is convenient for stacking and cleaning.
