Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a spray dust reduction device for building construction. Background Art

[0002] At present, the problem of dust pollution at construction sites is becoming increasingly prominent, seriously affecting the air quality of the construction environment and threatening the health of the surrounding environment and construction workers. To address this challenge, various dust reduction devices have emerged, and among them, spray dust reduction devices have been widely used due to their high efficiency and environmental protection characteristics. However, there are still some limitations in the existing spray dust reduction devices for building construction during use. First, many dust reduction devices are fixed in a certain position and cannot move flexibly, resulting in a limited dust reduction range. Second, some dust reduction devices cannot rotate omnidirectionally during the spraying process, resulting in uneven dust reduction effects and dust reduction blind spots. Summary of the Utility Model

[0003] In view of the above-mentioned prior art, the utility model aims to provide a spray dust reduction device for building construction, which can spray and rotate omnidirectionally at the building construction site, effectively improving the dust reduction effect and reducing the dust pollution at the construction site.

[0004] To achieve the above object, the technical solution of the embodiment of the utility model is realized as follows:

[0005] A spray dust reduction device for building construction includes a mobile vehicle, a water storage tank, a pump body, a spray gun, a lifting mechanism and a connecting frame. The mobile vehicle is provided with a water storage tank and a lifting mechanism. The top of the lifting mechanism is rotatably connected to the connecting frame. The spray gun is installed on the connecting frame. The spray gun is communicated with the pump body through a rotary joint. The pump body is arranged in the water storage tank. The rotation axis of the rotary joint coincides with the rotation axis of the connecting frame. The rotation axis of the rotary joint is located on one side of the symmetry plane of the spray gun in the vertical direction.

[0006] Further, the spray gun is communicated with the rotary joint through a first connecting pipe. The rotary joint is communicated with the pump body through a second connecting pipe. The pump body supplies water to the spray gun through the second connecting pipe, the rotary joint and the first connecting pipe.

[0007] Further, the connecting frame includes a horizontal plate and a vertical plate. The horizontal plate is rotatably connected to the lifting mechanism. Vertical plates are provided on both sides of the horizontal plate. First screws are provided on both sides of the spray gun. The vertical plates are provided with through holes passing through the first screws. Locking nuts are provided on the first screws.

[0008] Further, the vertical plate is provided with a support, the support is rotatably connected with a rotating shaft, the rotating shaft is provided with an external thread, the vertical plate is slidably connected with the horizontal plate, and the vertical plate is provided with a threaded hole matching the external thread.

[0009] Further, the rotating shaft is provided with a first knob.

[0010] Further, the lifting mechanism includes an electric telescopic rod and a pulling rope. The top of the electric telescopic rod is connected with a plurality of the pulling ropes. The lower end of the pulling rope is connected with a reel. The reel is rotatably connected with the mobile vehicle. The mobile vehicle is provided with a locking mechanism for fixing the reel.

[0011] Further, the locking mechanism includes a second bolt and a second knob. The second bolt is threadedly connected with the mobile vehicle. One end of the second bolt faces the reel, and the other end is provided with the second knob.

[0012] The beneficial effects of the present utility model are as follows: The mobile vehicle can move to the position to be dust-removed at the construction site for dust-removing operation. The mobile vehicle is equipped with a water storage tank to store a certain amount of water. The pump body pumps the water in the water tank into the spray cannon, and the water forms an atomized liquid when sprayed out from the spray cannon. The atomized liquid adsorbs and settles the airborne dust, reducing the amount of dust in the air. When the atomized liquid is sprayed out from the spray cannon, since the rotation axis of the connecting frame is located on one side of the symmetry plane of the spray cannon in the vertical direction, the reaction force generated by the atomized liquid discharged from the spray cannon is unbalanced, so that the spray cannon rotates, enabling the spray cannon to perform 360° rotary spraying around the construction site and reducing the dust at the construction site. The connecting frame is arranged on the lifting mechanism, and the lifting mechanism can be used to lift the spray cannon installed on the connecting frame to spray the construction site, improving the effect of spray dust removal at the construction site.

The mobile vehicle 1 is provided with a water storage tank 2 and a lifting mechanism 5. The top of the lifting mechanism 5 is rotatably connected to the connecting frame 6. The spray gun 4 is installed on the connecting frame 6. The spray gun 4 is communicated with the pump body 3 through a rotary joint 7. The pump body 3 is arranged in the water storage tank 2. The rotation axis of the rotary joint 7 coincides with the rotation axis of the connecting frame 6. The upper end of the rotary joint 7 is fixedly connected to the connecting frame 6, and the lower end of the rotary joint 7 is fixedly connected to the lifting mechanism 5. When the connecting frame 6 rotates relative to the lifting structure, the upper and lower ends of the rotary joint 7 rotate relatively, and the spray gun 4 can be continuously supplied with water when the connecting frame 6 rotates. The lower end of the connecting frame 6 is rotatably connected to the lifting mechanism 5 to improve the connection strength. The rotation axis of the rotary joint 7 is located on one side of the symmetry plane of the spray gun 4 in the vertical direction. The mobile vehicle 1 can move to the position to be dust-suppressed at the construction site for dust suppression operations. The mobile vehicle 1 is equipped with a water storage tank 2 to store a certain amount of water. The pump body 3 pumps the water in the water tank into the spray gun 4, and forms atomized liquid when spraying out from the spray gun 4. The atomized liquid adsorbs and settles the air dust, reducing the dust amount in the air. When the atomized liquid sprays out from the spray gun 4, since the rotation axis of the connecting frame 6 is located on one side of the symmetry plane of the spray gun 4 in the vertical direction, the reaction force generated by the atomized liquid discharged from the spray gun 4 is unbalanced, so that the spray gun 4 rotates, enabling the spray gun 4 to perform 360° rotary spraying around the construction site and reducing the dust at the construction site. The connecting frame 6 is arranged on the lifting mechanism 5, and the spray gun 4 installed on the connecting frame 6 can be lifted by the lifting mechanism 5 to spray the construction site, improving the effect of spray dust removal at the construction site.

[0020] Specifically, the spray gun 4 is communicated with the rotary joint 7 through a first connecting pipe 8, and the rotary joint 7 is communicated with the pump body 3 through a second connecting pipe 9. The pump body 3 supplies water to the spray gun 4 through the second connecting pipe 9, the rotary joint 7 and the first connecting pipe 8. Connecting with the rotary joint 7 through the first connecting pipe 8 and the second connecting pipe 9 facilitates the layout of the pipeline.

[0021] Specifically, the connecting frame 6 includes a horizontal plate 10 and a vertical plate 11. The horizontal plate 10 is rotatably connected to the lifting mechanism 5. Vertical plates 11 are provided on both sides of the horizontal plate 10. First screws are provided on both sides of the spray gun 4, and through holes for passing through the first screws are provided on the vertical plates 11. Locking nuts are provided on the first screws. The angle between the spray gun 4 and the horizontal plane can be adjusted. After adjusting to the appropriate position, the first screw is locked by using the locking nut, so as to horizontally clamp and fix the spray gun 4, and spray dust suppression in different directions can be carried out.

[0022] Specifically, the vertical plate 11 is provided with a support, the support is rotatably connected with a rotating shaft, the rotating shaft is provided with an external thread, the vertical plate 11 is slidably connected with the horizontal plate 10, and the vertical plate 11 is provided with a threaded hole matching the external thread. By rotating the rotating shaft to adjust the positions of the two vertical plates 11, when the rotating shaft rotates, the rotating shaft will push the vertical plate 11 to slide along the horizontal plate 10, so as to adjust the distance between the symmetry plane of the spray gun 4 in the vertical direction and the rotation axis of the connecting frame 6, and thus adjust the rotation speed of the spray gun 4.

[0023] Specifically, the rotating shaft is provided with a first knob for facilitating the rotation of the rotating shaft.

After the lifting adjustment is tightened, the reel is locked by the locking mechanism, so that the pull ropes tighten the electric telescopic rod from different directions, improving the stability of the electric telescopic rod.

[0026] Specifically, the locking mechanism includes a second bolt and a second knob 24. The second bolt is threadedly connected with the mobile vehicle 1, one end of the second bolt faces the reel, and the other end is provided with the second knob 24.
