Description

Technical Field

[0001] The utility model relates to the technical field related to dust suppression devices for municipal civil engineering projects, in particular to a dust suppression device for municipal civil engineering projects. Background Art

[0002] The construction of municipal roads, bridges, tunnels and other projects in municipal civil engineering projects will generate a lot of dust. The large accumulation of dust will cause great harm to the health of construction workers. Therefore, dust reduction equipment is needed to reduce dust on the construction site.

[0003] Most of the existing municipal civil engineering projects use fog cannons for dust removal operations. Since the fog cannon is an integrated structure, the water mist can only be blown to one place and the spray direction is always consistent. It is not convenient to adjust the spray angle and spray range of the fog cannon. As a result, the water spray dust reduction device has a small spraying dust reduction range when in use, and can only spray water at a fixed angle to reduce dust, which reduces the dust reduction effect and the dust removal effect is not ideal.

An adjustment component for adjusting the angle of the air cylinder 9 is provided on the frame 6. A threaded rod 11 is rotatably installed on the mounting frame 5. The bottom end of the threaded rod 11 is fixedly connected to the output end of a first reduction motor 12 fixedly installed on the mounting frame 5.

[0025] In detail, the first reduction motor 12 drives the threaded rod 11 to rotate, the rotation of the threaded rod 11 drives the sliding sleeve 13 to move, and the movement of the sliding sleeve 13 drives the fog cannon 7 to rotate through the connecting rod 14, so that the spraying angle of the fog cannon 7 in the vertical direction can be adjusted, which is convenient for adjusting the spraying angle of the fog cannon 7 according to actual spraying needs, improving the spraying efficiency and spraying range, improving the dust reduction effect of the fog cannon 7, and having high flexibility in use.

[0026] Among them, the swing assembly includes a disc 15 rotatably installed in the cavity, a second reduction motor 16 is fixedly installed on the car plate 1, the output end of the second reduction motor 16 is fixedly connected to the disc 15, a connecting column 17 is eccentrically installed on the disc 15, and a slide rail 18 is slidably installed on the outer surface of the connecting column 17, a toothed plate 19 is fixedly installed on the slide rail 18, and a gear 20 meshing with the toothed plate 19 is fixedly installed on the rotating shaft 3.

[0027] In detail, the second reduction motor 16 drives the disc 15 to rotate, and the rotation of the disc 15 drives the connecting column 17 to rotate accordingly. The rotation of the connecting column 17 cooperates with the slide rail 18 to drive the tooth plate 19 to reciprocate. The reciprocating motion of the tooth plate 19 drives the rotating shaft 3 and the mounting disk 4 to rotate reciprocatingly through the gear 20, thereby driving the mounting frame 5 and the fog cannon 7 to swing accordingly, and adjust the spraying angle of the fog cannon 7 in the horizontal direction. It is also possible to ensure that the first reduction motor 12 is always on during the spraying process, so that the fog cannon 7 swings back and forth, thereby increasing the spray dust reduction range of the fog cannon 7 and improving the dust reduction effect of the fog cannon 7.

[0028] The bottom end of the connecting column 17 extends outside the slide rail 18 and is fixedly mounted with a limit plate 21 . The limit plate 21 can prevent the slide rail 18 from being separated from the connecting column 17 , thereby ensuring the stability of the connection between the slide rail 18 and the connecting column 17 .

The limit sleeve 22 can guide and limit the movement of the tooth plate 19 to prevent the tooth plate 19 from shifting and tilting during the movement, thereby ensuring the stability of the tooth plate 19 during the movement.

[0032] Among them, a plurality of telescopic rods 26 are fixedly installed between the mounting frame 5 and the circular ring 23. The telescopic rods 26 can guide and limit the movement of the circular ring 23 to ensure the stability of the circular ring 23 during movement.

[0033] Among them, a plurality of air cylinders 9 are evenly distributed in an array along the circumference, which can improve the uniformity of the device during spraying.

[0034] When working, the fog cannon 7 sucks water in the water tank 2 through the water supply hose and sprays water mist through the air outlet of the fog cannon 7 and several wind tubes 9 to perform dust reduction operation. When the spray angle and spray range need to be adjusted, the electric push rod 24 is started. The circular ring 23 can be driven to move through the extension and contraction of the electric push rod 24. The movement of the circular ring 23 drives the wind tube 9 to rotate through the hinge rod 25, and the angle of the wind tube 9 is adjusted, so that the water mist sprayed by the fog cannon 7 can be sprayed in different directions through the several wind tubes 9, thereby expanding the spray dust reduction range of the fog cannon 7 and improving the dust reduction effect of the fog cannon 7. Then, the threaded rod 11 is driven to rotate through the first reduction motor 12, and the rotation of the threaded rod 11 drives the sliding sleeve 13 to move. The movement of the sliding sleeve 13 drives the fog cannon 7 to rotate through the connecting rod 14.

The second reduction motor 16 drives the disc 15 to rotate, and the rotation of the disc 15 drives the connecting column 17 to rotate accordingly. The rotation of the connecting column 17 cooperates with the limit sleeve 22 and the slide rail 18 to drive the tooth plate 19 to reciprocate. The reciprocating motion of the tooth plate 19 drives the rotating shaft 3 and the mounting plate 4 to rotate reciprocatingly through the gear 20, thereby driving the mounting frame 5 and the fog cannon 7 to swing accordingly, and the spraying angle of the fog cannon 7 in the horizontal direction can be adjusted. It is also possible to ensure that the first reduction motor 12 is always on during the spraying process, so that the fog cannon 7 swings back and forth, further increasing the spray dust reduction range of the fog cannon 7 and improving the dust reduction effect of the fog cannon 7.
