Description
Technical Field
[0001] The utility model belongs to the technical field of highway dust prevention, and particularly relates to a dust prevention device for highway construction. Background Technique
[0002] During the highway construction process, a large amount of dust and particulate matter will be generated. These dusts will not only pose a threat to the health of construction workers, but also pollute the surrounding environment, affecting air quality and visibility. Therefore, it is crucial to take effective dust prevention measures to reduce the spread of construction dust.
[0003] When some sprinkler dust prevention devices spray water, the spraying end is far from the road surface. By increasing the water pressure, the water source is sent to the road surface. The water sprayed out at a higher water pressure will generate an impact force on the surrounding dust when it contacts the dust, which will cause the dust to rise, instead aggravating the dust pollution. Therefore, a dust prevention device for highway construction is needed, which adopts low-position spraying and a extendable water spraying pipe to make the water spraying position close to the road surface position to prevent excessive water pressure from generating an impact on the dust.

Detailed implementation manners
[0021] In the following, embodiments of the dust-proof device for road construction of the present utility model will be described with reference to the accompanying drawings.
[0022] Figures 1-4 A dust-proof device for road construction according to an embodiment of the present utility model is shown, which includes a fixed box 2 installed on the right side of a sprinkler truck 1. Connecting plates 7 are welded to the front end and the rear end of the left side of the fixed box 2. Bolts 8 are provided at the top and the bottom of the right side of the connecting plate 7. The left end of the bolt 8 penetrates to the left side of the connecting plate 7 and is threadedly connected to the sprinkler truck 1. A main water sprinkling pipe 3 is fixedly installed on the right side of the fixed box 2. An expansion assembly 4 is arranged on the right side of the fixed box 2. Arc-shaped guide grooves 41 are opened at the top and the bottom of the right side of the fixed box 2. A guide post 42 is slidably connected to the inner cavity of the arc-shaped guide groove 41. A sliding pin 45 is fixedly connected to the rear end of the guide post 42. The sliding pin 45 is slidably connected to the inner cavity of a sliding seat 51. A spring 6 is sleeved on the surface of the sliding pin 45. One end of the spring 6 is welded to the sliding seat 51, and the other end of the spring 6 is welded to the sliding pin 45. Through the arrangement of the spring 6, an elastic pushing effect is exerted on the sliding pin 45, so that the guide post 42 can actively drive the auxiliary water sprinkling pipe 44 into the working position. The right end of the guide post 42 is fixedly connected to a fixing frame 43. An auxiliary water sprinkling pipe 44 is fixedly installed in the inner cavity of the fixing frame 43. A propulsion assembly 5 is arranged in the inner cavity of the fixed box 2. The propulsion assembly 5 includes a sliding seat 51 slidably connected to the inner cavity of the fixed box 2. A threaded pipe 54 is fixedly connected to the top of the front side of the sliding seat 51. The threaded pipe 54 is threadedly connected to the surface of a threaded rod 53. One end of the threaded rod 53 away from a stepping motor 52 is rotatably connected to the inner wall of the fixed box 2 through a bearing. A circular through hole 55 adapted to the threaded rod 53 is opened at the bottom of the front side of the sliding seat 51. Through the cooperation of the threaded pipe 54 and the threaded rod 53, a threaded propulsion effect is exerted on the sliding seat 51, so that the sliding seat 51 can slide in the inner cavity of the fixed box 2. With the cooperation of the circular through hole 55, space is reserved for the threaded rod 53, so that the two sliding seats 51 and the threaded rod 53 can move in cooperation with each other respectively, avoiding obstruction. Stepping motors 52 are fixedly installed on the front side and the rear side of the fixed box 2. The output shaft of the stepping motor 52 is fixedly connected to a threaded rod 53.
[0023] Working principle: When the utility model is in use, the user starts the sprinkler truck 1 to drive the fixed box 2 to move. At the same time, water source is input into the inner cavities of the main sprinkler pipe 3 and the secondary sprinkler pipe 44 through the sprinkler truck 1 to sprinkle the construction road surface. When sprinkling and dust prevention is carried out on a relatively wide road surface, the user turns on two stepping motors 52. The stepping motors 52 drive the threaded rod 53 to rotate. During the rotation of the threaded rod 53, the sliding seat 51 is driven to slide through the thread on its surface. During the sliding of the sliding seat 51, the sliding pin 45 is driven to move. During the movement of the sliding pin 45, the guide column 42 is driven to slide in the inner cavity of the arc-shaped guide groove 41, and at the same time, the secondary sprinkler pipe 44 is driven to move through the fixed frame 43. Under the guiding action of the arc-shaped guide groove 41, the secondary sprinkler pipe 44 moves to a horizontal position with the main sprinkler pipe 3, so as to expand the spraying range, make the water spraying position closer to the construction road surface, prevent the road surface from being impacted by a large water pressure, and stir up the dust on the road surface.
[0024] To sum up: The dust prevention device for highway construction sprinkles water on the construction road surface through the combined use of the sprinkler truck 1, the fixed box 2 and the main sprinkler pipe 3. At the same time, through the combined use of the expansion component 4 and the propulsion component 5, the sprinkling range is expanded, so as to achieve the purpose of preventing water flow from stirring up dust and making the sprinkling range adjustable.
