Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically a water-spraying tunnel dust suppression vehicle for ensuring safety during tunnel construction. Background Technology

[0002] During the construction process inside the tunnel, drilling, blasting, excavation and transportation operations will generate a large amount of dust. This dust floating in the air reduces the visibility inside the tunnel, which increases the difficulty and danger of construction and seriously affects the respiratory health of workers. In some cases, dust explosions may occur when the dust concentration is too high and there are flammable gases in the tunnel.

[0003] To ensure safety inside the tunnel, water-spraying tunnel dust suppression vehicles are used to deal with dust. However, in the application of existing water-spraying tunnel dust suppression vehicles, the vehicles have limited water storage capacity and the sprayed water cannot be recycled. This results in a short effective operating time for the water-spraying tunnel dust suppression vehicles, and a large amount of water accumulates in a short distance, affecting the work of the staff.

[0004] For example, invention application CN115554792A discloses a dust suppression vehicle for bridge and tunnel construction, including a water tank and a water pump. The input end of the water pump passes through one side of the water tank and is fixedly installed on the top surface of the vehicle frame. A flexible hose is connected to the end of the water pump away from the water tank. This invention installs multiple dust suppression nozzles, and an electric push rod can automatically control the up and down movement of the nozzles, making it suitable for dust suppression in tunnels of different heights.

[0005] Taking the aforementioned dust suppression vehicle as an example, the dust suppression vehicle sprays water directly during operation, which cannot be recycled. The water storage is limited, and the effective operating time of the water spray tunnel dust suppression vehicle is short. Summary of the Invention

[0006] The purpose of this invention is to provide a water-spraying tunnel dust suppression vehicle for ensuring safety during tunnel construction, thereby solving the problems raised in the prior art. To achieve the above objectives, the present invention provides the following technical solution: a water-spraying tunnel dust suppression vehicle for ensuring safety during tunnel construction, comprising a vehicle body, a water tank, a water spraying structure, and a vehicle platform. A collection box is provided at the bottom of the vehicle platform, and retractable wing plates are rotatably provided on both sides of the collection box. A transmission assembly is provided between the two retractable wing plates.

The fixing frame three is fixedly connected to the outer wall of the collection box. An arc-shaped frame is sleeved on the outer side of the retractable wing plate and fixedly installed on the outer side of the collection box. The two retractable wing plates are symmetrically arranged on both sides of the top of the collection box. The arc-shaped frame sleeved on the outer side of the retractable wing plate is fixedly installed on the outer side of the collection box. Without affecting the rotation of the retractable wing plate within a certain range, the arc-shaped frame seals the gap between the retractable wing plate and the collection box to reduce water leakage.

[0008] Preferably, the transmission assembly includes a forward and reverse motor and a dual-shaft reverse output gearbox located at the bottom of the vehicle body. The forward and reverse motor is fixedly installed on the outside of the dual-shaft reverse output gearbox. The output end of the forward and reverse motor is fixedly connected to the input end of the dual-shaft reverse output gearbox. The two output ends of the dual-shaft reverse output gearbox are respectively fixedly connected to two transmission shafts. A brake is sleeved on the outside of the transmission shaft. Multiple fixing brackets are fixedly connected between the brake and the outer wall of the dual-shaft reverse output gearbox. Two fixing brackets are fixedly connected between the dual-shaft reverse output gearbox and the collection box.

[0009] Preferably, the position control component includes a fixed frame 8 inserted at one end of the collection box and a fixed frame 6 provided at the bottom of the collection box. A sealing plug is fixedly connected to the side of the fixed frame 8 near the filter plate. Multiple connecting shafts are fixedly connected between the sealing plug and the filter plate. The hydraulic cylinder 2 drives the fixed frame 8 to move through the connecting vertical plate. The fixed frame 8 drives the filter plate to move through the sealing plug and the connecting shafts. The filter plate moves to the outside of the collection box. The movement of the filter plate pushes the impurities accumulated inside the collection box.

[0010] Preferably, the bottom of the fixed frame 8 is fixedly connected to four connecting vertical plates. One of the connecting vertical plates is provided with a hydraulic cylinder 2 on one side, and the other three connecting vertical plates are provided with two telescopic rods 3 on one side. The piston ends of the hydraulic cylinder 2 and the telescopic rods 3 are fixedly connected to the adjacent connecting vertical plates. The outer wall of the hydraulic cylinder 2 is fixedly connected to the fixed frame 6. A fixed frame 7 is sleeved on the outside of the telescopic rods 3. Under the action of the hydraulic cylinder 2 and the multiple telescopic rods 3, the fixed frame 8 can move horizontally stably. The fixed frame 7 is fixedly connected to the fixed frame 6.

[0011] Preferably, a first fixed frame is fixedly connected to the top of the sixth fixed frame. A hydraulic cylinder and multiple telescopic rods are fixedly connected between the top of the first fixed frame and the vehicle platform. Two electromagnets are fixedly connected to the bottom of the first fixed frame. A metal frame is threaded through each of the two electromagnets. One end of the metal frame is fixedly connected to the first fixed frame. The metal frame moves synchronously with the first fixed frame. Both electromagnets are fixedly connected to a dual-shaft reverse output gearbox. The dual-shaft reverse output gearbox moves up and down synchronously with the first fixed frame.

[0012] Preferably, a second fixed frame is fixedly connected between the ends of the two metal frames away from the first fixed frame. The top of the second fixed frame is provided with multiple telescopic rods, which are fixedly inserted into the vehicle panel. The piston end of the telescopic rod is fixedly connected to the second fixed frame. The multiple telescopic rods guide and limit the vertical movement of the second fixed frame and the metal frames, ensuring the stability of the vertical movement of the metal frames and the stability of the vehicle panel operation.

[0013] Preferably, the water guiding component includes a telescopic pipe fixedly connected to the outside of the collection tank, a rubber tube fixedly connected to one end of the telescopic pipe, a support box slidably installed inside the rubber tube, a storage groove is provided at the bottom of the vehicle panel, the support box and the rubber tube are both disposed inside the storage groove, the support box is fixedly connected to the vehicle panel, and the support box is slidably installed inside the rubber tube fixedly connected to one end of the telescopic pipe which can extend and retract in the vertical direction. The support box and the rubber tube do not affect the movement of the collection tank, and the support box is fixedly connected to the vehicle panel and cannot move vertically.

[0014] Preferably, a water guide vertical pipe is fixedly connected to the top of the support box, and a water pump is fixedly installed on the top of the vehicle platform. The top of the water guide vertical pipe passes through the vehicle platform and is fixedly connected to the water pump inlet. A second water guide bend is fixedly connected between the water pump outlet and the water storage tank. The water pump draws water from inside the collection tank through the water guide vertical pipe, the support box, the rubber hose, and the telescopic pipe. The water drawn by the water pump is transported to the water storage tank for storage through the second water guide bend.

[0015] Preferably, fixed brackets nine are fixedly connected to both sides of the fixed bracket eight. Bolts are threaded through the fixed bracket nine. Threaded grooves are opened on both sides of the collection box. The threaded grooves correspond one-to-one with the bolts. One end of the bolt is inserted into the threaded groove. The bolt is rotated to leave the threaded groove. After operating the two bolts, the fixation between the fixed bracket eight and the collection box is removed.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When this application is used, after the folding and unfolding wing plates are unfolded to a suitable angle, the control brake is activated to brake the drive shaft, and the folding and unfolding wing plates are limited. This allows the recovery frame, composed of two drive shafts, two folding and unfolding wing plates, and a collection box, to unfold. A foldable and retractable or extendable recovery frame is installed at the bottom of the vehicle platform to recover a portion of the water sprayed by the water spray structure, reducing water resource input during the dust suppression process in the tunnel to avoid dust explosions. At the same time, it does not make significant changes to the main body of the vehicle, ensuring the flexibility and convenience of using the tunnel dust suppression vehicle.

[0017] 2. When this application is in use, the movement of the filter plate pushes the impurities accumulated inside the collection box. Finally, the filter plate pushes the impurities out of the collection box and leaves the collection box. After the staff cleans the filter plate, the hydraulic cylinder two is controlled to drive the filter plate back into the collection box. Then, the rotating bolts fix the fixing frame eight to the collection box, completing the self-cleaning work of the recycling rack. Through the separable structure design of the fixing frame eight and the collection box, the hydraulic cylinder two can control the movement of the collection box to move away from the bottom of the vehicle platform to achieve the effect of water recycling, and can also control the movement of the filter plate to clean the inside of the collection box, ensuring the convenience of recycling rack operation.

[0018] 3. When this application is in use, the water pump is controlled to work at regular intervals. The water pump draws water filtered inside the collection box through the water guide vertical pipe, support box, rubber hose and telescopic pipe. The water is transported by the water pump to the water storage tank through the second water guide bend. The water sprayed by the water spray structure is collected by the recycling rack and then filtered and recycled to reduce water waste and ensure the effective endurance of the tunnel dust suppression vehicle.

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.

[0022] Example: Figures 1-13As shown, this invention provides a water-spraying tunnel dust suppression vehicle for tunnel construction safety, including a vehicle body 1, a water tank 2, a water spraying structure 3, and a vehicle platform 4.

A drive shaft 16 is fixedly threaded through the deployable and retractable wing plates 17. Fixing brackets 15 are rotatably mounted at both ends of the outer side of the drive shaft 16. The fixing brackets 15 are fixedly connected to the outer wall of the collection box 5. An arc-shaped frame 18 is fitted around the outer side of the deployable and retractable wing plates 17. An arc-shaped frame 18 is fixedly installed on the outside of the collection box 5. Two retractable wing plates 17 are symmetrically arranged on both sides of the top of the collection box 5. A transmission assembly is provided between the two retractable wing plates 17. A filter plate 30 is provided inside the collection box 5. A position control assembly is provided between the filter plate 30 and the vehicle body 4. The position control assembly includes a fixing frame 8 27 inserted at one end of the collection box 5 and a fixing frame 6 22 provided at the bottom of the collection box 5. A sealing plug 28 is fixedly connected to the fixing frame 8 27 near the filter plate 30. Multiple connecting shafts 29 are fixedly connected to the filter plate 30 on one side. Four connecting vertical plates 26 are fixedly connected to the bottom of the fixing frame 27. One of the connecting vertical plates 26 has a hydraulic cylinder 23 on one side, and the other three connecting vertical plates 26 each have two telescopic rods 24 on one side. The piston ends of the hydraulic cylinder 23 and the telescopic rods 24 are fixedly connected to the adjacent connecting vertical plate 26. The outer wall of the hydraulic cylinder 23 is fixedly connected to the fixing frame 22. A fixing frame 25 is sleeved on the outer side of the telescopic rods 24. Fixed frame 7 25 is fixedly connected to fixed frame 6 22. Fixed frame 8 is fixedly connected to the top of fixed frame 6 22. A hydraulic cylinder 6 and multiple telescopic rods 7 are fixedly connected between the top of fixed frame 8 and vehicle platform 4. Two electromagnets 12 are fixedly connected to the bottom of fixed frame 8. A metal frame 11 is threaded through each of the two electromagnets 12. One end of the metal frame 11 is fixedly connected to fixed frame 8. A water guiding component is provided between collection box 5 and water storage tank 2. A metal mesh plate 31 is fixedly embedded in the top of collection box 5.

[0023] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 A drive shaft 16 is fixedly inserted through the retractable wing plate 17. A fixing bracket 3 15 is rotatably installed at both ends of the outer side of the drive shaft 16. The fixing bracket 3 15 is fixedly connected to the outer wall of the collection box 5. The drive shaft 16 and the fixing bracket 3 15 are located at the top edge of the collection box 5. The two retractable wing plates 17 are symmetrically arranged on both sides of the top of the collection box 5 and can rotate. An arc-shaped frame 18 is fixedly installed on the outer side of the retractable wing plate 17. Without affecting the rotation of the retractable wing plate 17 within a certain range, the arc-shaped frame 18 seals the gap between the retractable wing plate 17 and the collection box 5 to reduce water leakage.

[0024] Specifically, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 In the transmission assembly, both the forward and reverse motor 13 and the dual-shaft reverse output gearbox 14 are located at the bottom of the vehicle platform 4. The forward and reverse motor 13 is fixedly installed on the outside of the dual-shaft reverse output gearbox 14, and the output end of the forward and reverse motor 13 is fixedly connected to the input end of the dual-shaft reverse output gearbox 14. The two output ends of the dual-shaft reverse output gearbox 14 are respectively fixedly connected to two drive shafts 16. Therefore, when the forward and reverse motor 13 is controlled to work, the transmission direction of the dual-shaft reverse output gearbox 14 is downward, the two drive shafts 16 rotate in opposite directions, and the two retractable wing plates 17 move towards the top sides of the collection box 5. The gearbox 14 unfolds or covers the top of the collection box 5. A brake 19 sleeved on the outside of the drive shaft 16 is fixedly connected to the outer wall of the dual-shaft reverse output gearbox 14. The brake 19 is used to brake the drive shaft 16, and the folding and unfolding wing plate 17 is limited. Two fixed brackets 21 are fixedly connected to the side of the dual-shaft reverse output gearbox 14 near the collection box 5. The fixed brackets 21 are fixedly connected to one side of the collection box 5. Under the action of the two fixed brackets 21 and the two drive shafts 16, the dual-shaft reverse output gearbox 14 moves synchronously with the collection box 5.

[0025] Specifically, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 In the position control component, the fixing bracket 8 27 is inserted into one end of the collection box 5. A sealing plug 28 is fixedly connected to the side of the fixing bracket 8 27 near the filter plate 30. The sealing plug 28 is inserted into the inside of the collection box 5 and contacts the inside of the collection box 5. The sealing plug 28 increases the sealing effect of the fixing bracket 8 27 on the collection box 5. Multiple connecting shafts 29 are fixedly connected between one side of the sealing plug 28 and the filter plate 30. The filter plate 30 and the fixing bracket 8 27 move synchronously. Fixing brackets 9 32 are fixedly connected to both sides of the fixing bracket 8 27. Bolts 33 are threaded through the fixing brackets 9 32. Threaded grooves 34 are opened on both sides of the collection box 5. The threaded grooves 34 correspond one-to-one with the bolts 33. One end of the bolt 33 is inserted into the threaded groove 34. The bolts 33 fix the fixing brackets 9 32 and the collection box 5 together. At this time, the fixing bracket 8 27 and the collection box 5 move synchronously.

[0026] The bottom of the fixed frame 8 27 is fixedly connected to four connecting vertical plates 26. One of the connecting vertical plates 26 is equipped with a hydraulic cylinder 23 on one side, and the other three connecting vertical plates 26 are equipped with two telescopic rods 3 24 on one side. The piston ends of the hydraulic cylinder 23 and the telescopic rods 3 24 are fixedly connected to the adjacent connecting vertical plates 26. The outer wall of the hydraulic cylinder 23 is fixedly connected to the fixed frame 6 22. The fixed frame 7 25, which is sleeved on the outside of the telescopic rods 3 24, is fixedly connected to the fixed frame 6 22. Under the action of the hydraulic cylinder 23 and the multiple telescopic rods 3 24, the fixed frame 8 27 can move horizontally stably.

[0027] A fixed frame 8 is fixedly connected to the top of the fixed frame 6 22. A hydraulic cylinder 6 and multiple telescopic rods 7 are fixedly connected between the top of the fixed frame 8 and the vehicle plate 4. The outer walls of the hydraulic cylinder 6 and the telescopic rods 7 are fixedly connected to the vehicle plate 4. The output ends of the hydraulic cylinder 6 and the telescopic rods 7 are fixedly connected to the fixed frame 8. Two electromagnets 12 are fixedly connected to the bottom of the fixed frame 8, and metal frames 11 are threaded through them. One end of the metal frame 11 is fixedly connected to the fixed frame 8. The metal frame 11 moves synchronously with the fixed frame 8. Both electromagnets 12 are fixedly connected to the dual-shaft reverse output gearbox 14. The dual-shaft reverse output gearbox 14 moves up and down synchronously with the fixed frame 8.

[0028] Two metal frames 11 are fixedly connected to a fixed frame 2 10 at the end away from the fixed frame 1 8. Multiple telescopic rods 2 9 set on the top of the fixed frame 2 10 are fixedly inserted into the vehicle platform 4. The piston end of the telescopic rod 2 9 is fixedly connected to the fixed frame 2 10. The multiple telescopic rods 2 9 guide and limit the up and down movement of the fixed frame 2 10 and the metal frame 11, ensuring the stability of the up and down movement of the metal frame 11 and ensuring the stability of the operation of the vehicle platform 4.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13In the water guiding assembly, the telescopic pipe 35 is fixedly connected to the collection box 5. One end of the telescopic pipe 35, which can extend and retract in the vertical direction, is fixedly connected to a rubber tube 37, and a support box 36 is slidably installed inside it. Both the support box 36 and the rubber tube 37 are located inside the storage groove 38 opened at the bottom of the vehicle platform 4. The support box 36 and the rubber tube 37 do not affect the movement of the collection box 5. The support box 36 is fixedly connected to the vehicle platform 4 and cannot move up and down. The water guiding vertical pipe 39 fixedly connected to the top of the support box 36 is fixedly connected to the water inlet of the water pump 40 fixedly installed on the top of the vehicle platform 4. The water outlet of the water pump 40 is fixedly connected to the water storage tank 2 by a second water guiding bend 41. Therefore, after the water pump 40 is controlled to work, the water pump 40 draws water from the inside of the collection box 5 through the water guiding vertical pipe 39, the support box 36, the rubber tube 37, and the telescopic pipe 35. The water drawn by the water pump 40 is transported to the inside of the water storage tank 2 for storage through the second water guiding bend 41.

[0030] The tunnel dust suppression vehicle consists of the vehicle body 1, water tank 2, water spray structure 3, vehicle platform 4, collection box 5, two retractable wing plates 17, transmission assembly, filter plate 30, position control assembly, water guiding assembly, metal mesh plate 31, etc. The working principle of the tunnel dust suppression vehicle is as follows: Hydraulic cylinder 16 is activated, pushing fixed frame 18 downwards. Fixed frame 18 then moves fixed frame 6 22 and two metal frames 11 downwards, causing the dual-shaft reverse output gearbox 14 and collection box 5 to move downwards. Once the bottom of collection box 5 is close to the ground, hydraulic cylinder 16 stops. Then, hydraulic cylinder 23 is activated, pushing fixed frame 8 27 to move outwards from the vehicle platform 4. Fixed frame 8 27 moves collection box 5 and dual-shaft reverse output gearbox 14, causing the two retractable wing plates 17 at the top of collection box 5 to completely leave the bottom of vehicle platform 4. Hydraulic cylinder 23 then stops. At this point, multiple telescopic rods 3 24, in conjunction with hydraulic cylinder 2 23, support collection box 5. Subsequently, forward and reverse motor 13 is activated, rotating forward. Under the transmission of dual-shaft reverse output gearbox 14 and two drive shafts 16, the two retractable wing plates 17 flip. The angle between the side of the retractable wing plate 17 and the top surface of the collection box 5 is controlled to be between 120° and 160°. When the retractable wing plate 17 is unfolded to a suitable angle, the brake 19 is activated to brake the drive shaft 16. The retractable wing plate 17 is limited, which allows the recycling frame composed of the two drive shafts 16, the two retractable wing plates 17, and the collection box 5 to unfold. A foldable and retractable recycling frame is installed at the bottom of the vehicle platform 4 to recover a portion of the water sprayed by the water spray structure 3 (the operation of the water spray structure 3 is an existing technology application; for details, please refer to the patent document with application publication number CN115554792A). This reduces the water input during the dust suppression process in the tunnel to avoid dust explosions, while not making significant changes to the shape of the vehicle body 1, ensuring the flexibility and convenience of using the tunnel dust suppression vehicle.

[0031] Water falling into the recycling rack enters the collection box 5 after passing through the metal mesh plate 31. The filter plate 30 is set inside the collection box 5, separating the telescopic pipe 35 from the metal mesh plate 31. The water entering the telescopic pipe 35 is first filtered by the filter plate 30, and the rubber tube 37 fixedly connected to the telescopic pipe 35 can slide on the outside of the support box 36 according to a preset trajectory. Using the telescopic pipe 35 does not affect the communication between the collection box 5 and the inside of the rubber tube 37 during the movement. The water pump 40 is controlled to work at regular intervals. The water pump 40 draws the filtered water inside the collection box 5 through the water guide vertical pipe 39, the support box 36, the rubber tube 37, and the telescopic pipe 35. The water is transported by the water pump 40 to the water storage tank 2 through the second water guide bend 41. The recycling rack catches and filters part of the water sprayed by the water spray structure 3, reducing water waste and ensuring the effective endurance of the tunnel dust suppression vehicle.

[0032] The forward and reverse motor 13 is controlled to work in reverse, and the two retractable wings 17 rotate back to the top of the collection box 5, causing the collection frame to enter a folded state. Then, the hydraulic cylinder 23 is controlled to retract, driving the collection box 5 and the retractable wings 17 back to the bottom of the vehicle platform 4. Then, the electromagnet 12 is controlled to work and is fixed to the iron metal frame 11 by magnetic attraction. The horizontal movement of the dual-shaft reverse output gearbox 14 and the collection box 5 is restricted, and the rotating bolt 33 is disengaged from the threaded groove 34. After operating the two bolts 33, the fixation between the fixing frame 27 and the collection box 5 is removed. Then, the hydraulic cylinder 23 is controlled to work to extend. At this time, the hydraulic cylinder 23 drives the fixing frame 27 to move through the connecting vertical plate 26. The fixing frame 27 drives the filter plate 30 to move through the sealing plug 28 and the connecting shaft 29. The filter plate 30 moves outward from the collection box 5, pushing the impurities accumulated inside the collection box 5. Finally, the filter plate 30 pushes the impurities out of the collection box 5 and leaves the collection box 5. After the staff cleans the filter plate 30, the hydraulic cylinder 23 is controlled to drive the filter plate 30 back into the collection box 5. Then, the rotating bolt 33 fixes the fixing frame 27 to the collection box 5, completing the self-cleaning work of the recycling rack. Through the separable structure design of the fixing frame 27 and the collection box 5, the hydraulic cylinder 23 can control the collection box 5 to move away from the bottom of the vehicle platform 4 to achieve the effect of water recycling, and can also control the filter plate 30 to move to clean the inside of the collection box 5, ensuring the convenience of recycling rack operation.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
