Abstract
Description
Technical Field
[0001] This utility model relates to the field of building environmental protection technology, and more specifically, to a dust prevention and control device for building construction that is easy to move. Background Technology
[0002] In recent years, my country has attached great importance to infrastructure construction. With the continuous acceleration of urbanization, roads and buildings under construction can be seen everywhere. In the process of road and building construction, a large amount of dust will inevitably be generated. Dust particles are very small and their surfaces can often adsorb other gaseous or liquid harmful substances. Long-term inhalation of dust can cause great harm to the human body. Therefore, it is necessary to treat the dust generated by construction through dust prevention and control devices to play an environmental protection role.
[0003] Based on the above, the inventors have found that existing dust suppression devices are generally fixed in one place, which is inconvenient to move. The range of dust suppression is small, and the device can only be moved manually, which is very inconvenient and increases the labor burden of workers. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a construction dust suppression device that is easy to move, in order to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dust suppression device for construction that is easy to move. This solution is equipped with an automatically adjustable spray assembly to enable the spray assembly to move. At the same time, the movement path can be extended to expand the spray range and improve the dust suppression effect of the device. Furthermore, a guide assembly is set up to provide support for the movement of the spray assembly, and the movement resistance is reduced by self-rotation to ensure the stability of the spray assembly's movement.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A mobile dust suppression device for construction includes a support frame, a movable frame is provided on the outer side of the upper end of the support frame, and a rack and a support plate are fixedly connected to the rear side of the support frame.

A water pipe is fixedly connected to the outer side of the movable frame, and a drive motor is fixedly connected to the inner side of the movable frame. A gear ring is fixedly connected to the output end of the drive motor.
[0009] The guiding mechanism includes two symmetrically arranged guide rods. A sliding sleeve is fitted on the upper side of the opposite face of the two guide rods. Several grooves are opened at the upper end of the guide rods. A pair of sliding grooves are opened below the sliding sleeves.

[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) This solution sets up a rotating gear ring, which meshes with the rack, thereby driving the moving frame and water pipe to move and adjust the spray position, thus realizing the movement of the spray assembly. At the same time, multiple support frames are stacked and fixed by bolts and positioning grooves, extending the movement path of the spray components. Compared with the existing technology, the solution sets up an automatically adjustable spray assembly to realize the movement of the spray assembly. At the same time, the movement path can be extended to expand the spray range and improve the dust prevention and dust reduction effect of the device.
[0019] (2) By setting a guide mechanism, the moving frame drives the sliding sleeve to slide on the outside of the guide rod. The sliding sleeve plays a limiting support role on the moving frame on the guide rod. During the movement of the sliding sleeve, the moving ball rubs against the groove and rotates, reducing the moving resistance of the sliding sleeve. Compared with the prior art, the guide component plays a moving support role for the spray assembly. At the same time, the moving resistance is reduced by the rotation method, ensuring the moving stability of the spray assembly. Attached Figure Description

A water pipe 6 is fixedly connected to the outer side of the movable frame 2, and a drive motor 7 is fixedly connected to the inner side of the movable frame 2. A gear ring 8 is fixedly connected to the output end of the drive motor 7.
[0028] The guide mechanism 5 includes two symmetrically arranged guide rods 9. A sliding sleeve 10 is fitted on the upper side of the opposite face of the two guide rods 9. Several grooves 11 are opened at the upper end of the guide rods 9. A pair of sliding grooves 12 are opened at the lower side of the sliding sleeve 10. Several sets of movable balls 13 are movably connected to the inner side of the sliding grooves 12. The guide mechanism 5 is provided to ensure the movement stability of the spray component.
[0029] See Figure 4 A set of positioning grooves is provided on both sides of the support frame 1, and the bottom sides of the support frame 1 are triangularly arranged. By using bolts to cooperate with the positioning grooves, the support frame 1 can be stacked and fixed, extending the movement path of the spray component.
[0030] See Figure 1The rack 3 is located above the support plate 4, and both sides of the rack 3 and the support plate 4 are flush with both sides of the support frame 1. The spraying component is moved and supported by the support plate 4.
[0031] See Figure 2 The toothed ring 8 is located on one side of the rack 3 and is meshed with the rack 3. When the drive motor 7 is started, the toothed ring 8 is rotated and meshed with the rack 3, thereby driving the entire moving frame 2 to move.
[0032] See Figure 2 A spray head is fixedly connected to the top of the water pipe 6. The spray head faces the front of the support frame 1. Spray water is delivered through the water pipe 6 and sprayed onto the construction position through the spray head for dust prevention and dust reduction.
[0033] See Figure 3 The guide rod 9 is T-shaped and fixedly connected to the support plate 4. The sliding sleeve 10 is U-shaped and fixedly connected to the bottom of the movable frame 2. The movable frame 2 drives the sliding sleeve 10 to slide outside the guide rod 9. The sliding sleeve 10 plays a limiting and supporting role on the movable frame 2 by the guide rod 9.
[0034] See Figure 3 The two sliding grooves 12 are respectively adapted to the two guide rods 9. One side of the movable ball 13 is in contact with the groove 11.
