Description

Technical Field

[0001] The present invention belongs to the technical field of road construction, and particularly relates to a dust reduction device for road and bridge construction and its working method. Background Art

[0002] With the continuous improvement of the road construction market system in China, roads, as an important infrastructure for national economic development, are playing an increasingly important role. During the process of road and bridge construction, a large amount of dust and garbage are often generated at the construction site, which not only affects the construction quality but also causes great pollution to the surrounding environment.

[0003] However, many existing dust reduction devices usually adopt a single cleaning method, such as only using a brush or a vacuum cleaner. This single cleaning method cannot completely remove the dust and garbage on the road surface, and its cleaning efficiency is low, and the dust reduction effect is limited. Some devices only rely on simple brush heads or water spraying devices for cleaning, and often cannot completely remove the fine dust and garbage on the road surface. Especially in a dry and windy environment, the road surface is very easy to raise dust again after cleaning.

[0004] In addition, existing dust reduction devices also have obvious defects in garbage recycling. Many devices lack an effective garbage recycling mechanism, resulting in the dust and garbage during the cleaning process cannot be effectively collected and processed, which not only affects the cleanliness of the construction environment but also may cause secondary pollution to the surrounding environment. There are also some devices that are more complex to operate and require multiple people to cooperate to complete the cleaning and dust reduction work, which not only increases the labor cost but also reduces the work efficiency.

[0005] Therefore, those skilled in the art have proposed a dust reduction device for road and bridge construction and its working method, aiming to improve the cleanliness of the construction environment, reduce the spread of dust, and improve the construction operation conditions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following further describes in detail the embodiments of the present invention in conjunction with the drawings. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0037] Embodiment 1: The present invention provides a dust reduction device for road and bridge construction, including: a vehicle body assembly 100, serving as the overall basic framework; a first cleaning assembly 200, arranged at the front end of the vehicle body assembly 100 for primary cleaning; a second cleaning assembly 300, arranged at the rear side of the first cleaning assembly 200 for secondary cleaning; a recycling and dust reduction assembly 400, arranged at the rear side of the second cleaning assembly 300 for recycling the dust and garbage after secondary cleaning and spraying the cleaned road surface.

[0038] The vehicle body assembly 100 further includes a vehicle frame 101. Rear wheels 102 are installed on both sides of the rear end of the vehicle frame 101. A first support frame 103 is fixedly installed in the middle of the vehicle frame 101. A support plate 104 is fixedly installed on the first support frame 103. A second support frame 105 is fixedly installed between the vehicle frames 101 and at the front end of the first support frame 103. A front wheel 106 is fixedly installed at the lower end of the first support frame 103. The front wheel 106 and the rear wheels 102 can facilitate the movement of the overall device, enabling the device to clean and reduce dust on the road and bridge surface during movement.

[0039] The first cleaning assembly 200 includes a housing 201 arranged above the first support frame 103. An electrical box 202 and a motor 203 are fixedly installed on the support plate 104. The motor 203 is charged by a battery inside the electrical box 202. The housing 201 is used to protect components such as the electrical box 202 and the motor 203. A first pulley 204 is fixedly installed at the output end of the motor 203. Two bearing seats 208 are fixedly arranged on the second support frame 105. A main shaft 207 is installed on the bearing seats 208. A second pulley 206 is fixedly installed on one side of the main shaft 207 at the output end of the motor 203. A first belt 205 is arranged between the first pulley 204 and the second pulley 206. First bevel gears 209 are fixedly installed on both sides of the main shaft 207. When the motor 203 is started, the motor 203 drives the first pulley 204 to rotate. The first pulley 204 drives the second pulley 206 to rotate through the first belt 205. The rotation of the second pulley 206 drives the main shaft 207 to rotate on the bearing seats 208, causing the first bevel gears 209 on the main shaft 207 to rotate accordingly.

[0040] At the upper end of the second support frame 105 and on both sides of the bearing seat 208, third pulleys 211 are installed. At the upper ends of the third pulleys 211, second bevel gears 210 are fixedly installed. The first bevel gear 209 meshes with the second bevel gear 210. At the connection between both sides of the second support frame 105 and the vehicle frame 101, mounting arms 212 are movably arranged. Above the front ends of the mounting arms 212, fourth pulleys 214 are arranged. Between the third pulleys 211 and the fourth pulleys 214, second belts 213 are arranged. Below the front ends of the mounting arms 212 and on the same rotating shaft as the fourth pulley 214, angle brushes 215 are fixedly installed. Between the middle of the front end of the second support frame 105 and the two mounting arms 212, a spring connecting member 216 is installed. The spring connecting member 216 is composed of a spring and a spring hinge. The spring connecting member 216 plays a buffering role for the mounting arms 212 of the angle brushes 215, can effectively reduce the impact and wear on the angle brushes 215 during the cleaning process, and at the same time protects the road surface from damage, thereby extending the service life of the device and reducing the maintenance cost. The first bevel gear 209 rotates, driving the meshing second bevel gear 210 to rotate, so that the third pulley 211 coaxial with the second bevel gear 210 rotates accordingly. The third pulley 211 drives the fourth pulley 214 to rotate through the second belt 213, so that the angle brush 215 on the same rotating shaft as the fourth pulley 214 rotates. Through the operation of the angle brush 215, the road surface is initially cleaned.

[0041] The second cleaning assembly 300 includes a third belt 301 arranged on the first pulley 204. On the first pulley 204, a first belt 205 and a third belt 301 are arranged. Between the first cleaning assembly 200 and the recycling and dust reduction assembly 400 and located between the vehicle frames 101, a rotary brush 303 is arranged. On one side of the rotary brush 303, a fifth pulley 302 is fixedly installed. Between the first pulley 204 and the fifth pulley 302, a third belt 301 is installed. The motor 203 drives the first pulley 204 to rotate. The first pulley 204 drives the first belt 205 and the third belt 301 arranged thereon to rotate. Through the third belt 301, the fifth pulley 302 is driven to rotate, so that the fifth pulley 302 drives the rotary brush 303 to operate, secondarily cleaning the road surface and brushing the dust and garbage cleaned into the recycling and dust reduction assembly 400.

[0042] The dust collection and recycling component 400 includes a box body 401 disposed behind the rotary brush 303. A controller 402 and a handle 404 are installed at the upper end of the box body 401. The inner cavity of the box body 401 is divided into a recycling box 409 and a water tank 410 by a partition plate 408. Water injection ports are provided on both sides of the upper end of the water tank 410 and located on both sides of the controller 402, and a sealing plug 403 is arranged at the water injection ports. Before the overall device operates, the water tank 410 is filled with water through the water injection ports, and the sealing plug 403 is used to prevent water from overflowing. A water level observation window 405 is arranged at the rear end of the water tank 410 for observing the water level in the water tank 410. Below the front end of the recycling box 409 and behind the rotary brush 303, a dust tray 411 is arranged. The dust tray 411 is set as an anti-dust plate in the inner cavity of the recycling box 409 and a dust-bearing plate at the lower side of the box body 401. When the rotary brush 303 sweeps dust and garbage into the recycling box 409, it is convenient to sweep in through the dust-bearing plate, and the folded anti-dust plate is used to prevent dust and garbage from leaving the recycling box 409. Water pipes 406 are installed on both sides of the water tank 410, and electromagnetic valves 407 are arranged on the water pipes 406. The opening and closing and the flow rate of the electromagnetic valves 407 are controlled by the controller 402. Multiple groups of spray heads 412 are arranged at the inner cavity of the dust-bearing plate of the water pipe 406. The outermost two spray heads of the spray heads 412 are set as L-shaped and spray to both sides respectively, so that the spraying area is large. After being cleaned by the corner brush 215 and the rotary brush 303 successively twice, the cleaned road surface is wetted by the spray heads 412. The wetted road surface can effectively reduce the raising of dust. The water can combine tiny particles together, thereby reducing the possibility of their suspension in the air. After being cleaned and wetted, the road surface maintains a certain humidity, which can prevent the originally cleaned road surface from re-dusting due to drying under the action of driving vehicles or wind, achieving the dust reduction effect.

[0043] Embodiment 2: The present invention also provides a dust reduction method for road and bridge construction, including the following steps:

[0044] S1. By pushing the handle and assisted by the front wheels and the rear wheels, the dust reduction device is pushed to the working location and continuously moved to clean the road surface.

[0045] S2. The motor is started through the controller, so that the motor drives the first belt pulley to rotate, and the first belt pulley drives the second belt pulley and the fifth belt pulley to rotate through the first belt and the third belt respectively.

[0046] S3. The rotation of the second belt pulley drives the main shaft to rotate on the bearing seat, so that the first bevel gear rotates accordingly, and the meshing second bevel gear rotates.

[0047] S4. The rotation of the second bevel gear drives the coaxial third belt pulley to rotate, so that the second belt on the third belt pulley drives the fourth belt pulley to rotate, and the corner brush coaxial with the fourth belt pulley starts to rotate and work to initially clean the road surface, and the spring connector plays a buffering role for the mounting arm of the corner brush.

[0048] When the corner brush is working, the third belt drives the fifth pulley to rotate, causing the rotary brush to rotate accordingly to further clean the road surface.

[0049] S6. The dust and garbage after being cleaned by the rotary brush enter the recycling bin through the ash tray. The ash tray is arranged as a special-shaped dust-proof plate in the inner cavity of the bin to prevent the dust and garbage from escaping from the recycling bin.

[0050] S7. When starting the motor, the solenoid valve is started at the same time, so that the water tank filled with water is sprayed out by the spray head through the water delivery pipe during the movement of the vehicle body to perform dust suppression treatment on the road surface cleaned by the corner brush and the rotary brush.
