[0020] Combination Figure 1-5 As shown, a roadway dust removal device includes: a mounting trolley 1, a drive assembly 2, a speed regulating assembly 3, a spray bar 4, and an auxiliary trolley 5; The installation trolley 1 includes a body 11 and rollers 13, with the rollers 13 located on both sides of the body 11 in the left-right direction. The drive assembly 2 includes a drive box 21 and an impeller 22. The drive box 21 is fixedly connected to the top of the body 11. The drive box 21 has a water-containing space 211 inside, and the impeller 22 is installed in the water-containing space 211. The impeller 22 is rotatably connected to the drive box 21. A water inlet pipe 212 is fixedly connected to the rear side of the drive box 21. The water inlet pipe 212 is used to connect to a high-pressure water pipe, and the interior of the water inlet pipe 212 communicates with the water-containing space 211. The speed regulating assembly 3 includes a drive gear set 31, a transmission chain 32, and a driven gear 33. The drive gear set 31 is fixedly connected to the drive assembly 21. The drive rod 23 and the drive gear set 31 are located outside the drive box 21 and above the vehicle body 11. The driven gear 33 is fixedly connected to the outer periphery of the transmission rod 12. The top of the vehicle body 11 is provided with a mounting port 111. The transmission chain 32 is connected to the drive wheel and the driven gear 33 through the mounting port 111. The auxiliary trolley 5 is spaced apart on one side of the mounting trolley 1 in the left and right directions. One end of the spray rod 4 is installed on the mounting trolley 1 and the other end is installed on the auxiliary trolley 5. The spray rod 4 is provided with a water supply channel 41 inside, which is connected to the accommodating space 211. The spray rod 4 is provided with multiple nozzles 42, which are connected to the water supply channel 41.

[0021] For example, the installation trolley 1 also includes a transmission rod 12, which passes through the trolley body 11 and extends in the left-right direction. The rollers 13 are respectively fixedly connected to both ends of the transmission rod 12. When using the roadway dust removal device of this application, the high-pressure water flow impacts the impeller 22 to rotate. The impeller 22 drives the drive gear set 31 to rotate through the drive rod 23. Under the transmission action of the transmission chain 32, the driven gear 33 drives the transmission rod 12 to rotate, causing the rollers 13 to roll forward. Thus, the installation trolley 1 and the auxiliary trolley 5 move together along the roadway. The auxiliary trolley 5 is spaced apart on one side of the installation trolley 1, which helps to enhance the balance of the movement of the roadway dust removal device. The drive box 21 can hold high-pressure water flow, and the water flow can enter the spray bar 4 and spray out into the roadway through the nozzle 42. This allows the roadway dust removal device to automatically spray water to remove dust while moving in the roadway, which is conducive to efficient use of resources and improved dust removal efficiency. After the dust removal work in the set area is completed, the water source of the high-pressure water pipe is turned off, and the roadway dust removal device can stop moving and spraying water, greatly reducing manual intervention.

[0022] Furthermore, the driving gear set 31 includes a first gear 311, a second gear 312, and a third gear 313 with successively decreasing gear diameters. The first gear 311, the second gear 312, and the third gear 313 are respectively connected to the impeller 22 for transmission. One of the first gear 311, the second gear 312, and the third gear 313 is connected to the driven gear 33 for transmission via the transmission chain 32.

[0023] By switching the transmission chain 32 to connect with different drive gear sets 31, the speed regulation function of the installation trolley 1 can be realized, which is beneficial for the dust removal device to adapt to various roadway slopes or adjust the travel and water spraying time according to the dust accumulation thickness. For example, when the transmission chain 32 is connected to the first gear 311, the first gear 311 has low speed and high torque, which is suitable for the installation trolley 1 to climb slopes; when the transmission chain 32 is connected to the third gear 313, the installation trolley 1 moves at high speed, which is suitable for flat areas.

[0024] Furthermore, the first gear 311, the second gear 312, and the third gear 313 are sequentially positioned away from the drive housing 21. This facilitates step-by-step speed adjustment of the drive speed of the mounting trolley 1.

[0025] Furthermore, the drive assembly 2 also includes a drive rod 23, which passes through the drive housing 21 and extends in the left-right direction. The drive rod 23 is fixedly connected to the impeller 22, and the inlet of the water inlet pipe 212 is positioned opposite to the drive rod 23. The drive rod 23 is rotatably connected to the drive housing 21. This effectively ensures that the impact force of the high-pressure water flow within the drive housing 21 can provide continuous power for the rotation of the impeller 22.

[0026] In some embodiments, the first gear 311, the second gear 312 and the third gear 313 are respectively fixedly connected to the drive rod 23.

[0027] Furthermore, the spray bar 4 includes a first bar 43, a second bar 44, and a third bar 45 connected in sequence. The first bar 43, the second bar 44, and the third bar 45 together define the water delivery channel 41. The first bar 43 and the third bar 45 extend vertically, and the second bar 44 extends horizontally. The bottom of the first bar 43 is installed above the vehicle body 11, and the bottom of the third bar 45 is installed above the auxiliary trolley 5. The two ends of the second bar 44 are respectively installed at the top of the first bar 43 and the top of the third bar 45. The first bar 43, the second bar 44, and the third bar 45 are respectively provided with nozzles 42.

[0028] The second rod 44 can span across the roadway, making it convenient to place the installation trolley 1 and the auxiliary trolley 5 close to both sides of the roadway when installing the roadway dust removal device. While the installation trolley 1 and the auxiliary trolley 5 move forward together, the nozzles 42 on the first rod 43, the second rod 44 and the third rod 45 spray water, which is beneficial for large-scale dust removal in the roadway and effectively improves dust removal efficiency.

[0029] Furthermore, the first rod 43 is detachable from the vehicle body 11 and the second rod 44, respectively, and the third rod 45 is detachable from the auxiliary trolley 5 and the second rod 44, respectively.

[0030] Before the dust removal device in the roadway is officially started, the height of the first rod 43 and the third rod 45, the width of the second rod 44, the number of nozzles 42 and the water spraying angle can be adjusted in advance according to the shape of the roadway cross section to ensure the water spraying effect of the spray rod 4 on the roadway and to facilitate the carrying and transportation of the spray rod 4.

[0031] In some embodiments, to better connect the spray bar 4, a water outlet pipe 213 is fixedly connected to the front side of the drive box 21. The water outlet pipe 213 is installed on the rear side of the first rod body 43, and the accommodating space 211 is connected to the water supply channel 41 through the interior of the water outlet pipe 213. The water flow from the water inlet pipe 212 on the rear side of the drive box 21 first strikes the impeller 22 to make it rotate before entering the water outlet pipe 213 on the front side of the drive box 21, which can make reasonable use of the power of the high-pressure water flow.

[0032] In some embodiments, the nozzle 42 includes an upper nozzle 42, an outer nozzle 42, and an inner nozzle 42. Multiple upper nozzles 42 are spaced apart on the top of the second rod 44. Multiple outer nozzles 42 are spaced apart on the side of the first rod 43 away from the third rod 45. Multiple outer nozzles 42 are spaced apart on the side of the third rod 45 away from the first rod 43. At least one inner nozzle 42 is provided on the side of the first rod 43 near the third rod 45, and at least one inner nozzle 42 is provided on the side of the third rod 45 near the first rod 43. The spray bar 4 is roughly U-shaped and can span the tunnel cross-section. The upper nozzle 42 is used to wash away dust accumulated on the tunnel roof, the two outer nozzles 42 wash the tunnel sides, and the two inner nozzles 42 wash the tunnel floor, which facilitates full-section dust removal of the tunnel.

[0033] To enhance the balance of the installation trolley 1, the installation trolley 1 further includes front wheels 14, which are mounted on both sides of the trolley body 11 in the left-right direction and are spaced in front of the rollers 13. For example, the auxiliary trolley 5 has four wheels, enabling the tunnel dust removal device to maintain balanced water spraying as it moves forward.

[0034] Furthermore, the drive assembly 2 also includes a mounting base 24, which is fixedly connected to the top of the vehicle body 11, and the drive box 21 is fixedly connected to the top of the mounting base 24. The mounting base 24 facilitates the installation of the speed control assembly 3, ensuring both sufficient space for the drive gear set 31 to move above the vehicle body 11 and easy access for operators to inspect and adjust the transmission chain 32.

[0035] The present invention also provides a method for dust removal in roadways, which uses the aforementioned dust removal device and includes the following steps: The dust removal device is placed in the tunnel, with its front-to-back direction aligned with the tunnel's extension direction. High-pressure water is injected into the drive box via a high-pressure water pipe connected to the water inlet pipe. The high-pressure water causes the impeller to rotate, driving the installation trolley forward and causing the nozzles of the spray bar to spray water to remove dust from the tunnel.

[0036] The operator selects the appropriate drive gear from the drive gear set 31 according to the roadway and connects it for transmission. After the high-pressure water pipe is installed and the water source is connected, the roadway dust removal device can automatically move forward and spray water to remove dust from the roadway. After the roadway dust removal device completes the dust removal task, the water source is turned off, which helps to save labor time and labor costs, improve work efficiency, and improve operational safety.

[0037] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
