Description

Technical Field

[0001] The utility model relates to the technical field of spray dust removal, in particular to a construction environmental protection dust removal device. Background Technique

[0002] At present, during building construction or road construction, a large amount of dust will float in the air in the construction area. At present, most of the dust removal during construction is carried out by a water spraying vehicle to remove the dust in the air. However, the spraying angle and range of the existing water spraying device are small, so there may be dead corners in the dust reduction area around the device. Therefore, a construction environmental protection dust removal device is needed to solve the above problems.

[0003] A construction environmental protection dust removal device with the publication number of CN220257527U includes a moving seat. A water supply component is arranged on the moving seat. A dust reduction component is arranged outside the water supply component. A driving component and a fixing component are arranged outside the dust reduction component. The fixing component is connected with the driving component. The water supply component is arranged in the fixing component. An adjusting component and a limiting component are arranged in the dust reduction component. In the utility model, when the adjusting component rotates forward and the dust reduction component moves to the highest position, the driving component is controlled to work. The working driving component drives the dust reduction component to rotate outside the water supply component. The water in the water supply component can be sprayed into the surrounding air without dead angles by 360 degrees from the rotating dust reduction component. Moreover, due to the high height of the dust reduction component, the higher dust reduction component increases the dust reduction area of water, so that the dust in the air in a large area around the device can be removed without dead angles.

[0004] However, there is a defect in this mechanism that the lifting mechanism is manually adjusted, which is time-consuming and laborious. Content of the Utility Model

[0005] The purpose of the utility model is to provide a construction environmental protection dust removal device to solve the problems existing in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A construction environmental protection dust removal device includes a transport vehicle 1, a fixed bracket 2, a water tank 21, a telescopic pipe 4 and a lifting platform 9.

Detailed Embodiments

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: a construction environmental protection dust removal device, including a transport vehicle 1, a fixed bracket 2, a water tank 21, a telescopic pipe 4 and a lifting platform 9. The water tank 21 and the fixed bracket 2 are arranged on the transport vehicle 1. A matching guide sleeve 3, a guide rod 6 and a matching threaded sleeve 5, a threaded rod 7 are provided between the lifting platform 9 and the fixed bracket 2. The top of the telescopic pipe 4 is connected to the lifting platform 9 through a flange. The telescopic pipe 4 is connected to a water spray pipe 11 through a sealing ring, and the water spray pipe 11 is supported on the lifting platform 9 through a bearing.

[0017] A motor 8 is provided below the lifting platform 9. The output end of the motor 8 is provided with a driving gear 12 and is located above the lifting platform 9. A driven gear 10 meshing with the driving gear 12 is provided on the water spray pipe 11; the top of the threaded rod 7 is fixedly connected to a driven shaft 13 through a fixing pin 20, and a sliding gear 14 meshing with the driving gear 12 and capable of sliding up and down is provided on the driven shaft 13. A boss 19 is provided at the lower end of the driven shaft 13, and bearings are provided above and below the boss 19, and the upper part is limited by a flange.

[0018] The specific working principle is as follows:

[0019] When the height needs to be adjusted, use the nut 16 to press down the fork 17, so that the fork 17 drives the sliding gear 14 to mesh with the driving gear 12. The motor 8 rotates forward and backward, indirectly driving the threaded rod 7 to rotate forward and backward, so that the lifting platform 9 moves up and down; when the height does not need to be adjusted, adjust the nut 16 to move upward. Under the action of the compression spring 18 below the fork 17, the sliding gear 14 is driven to disengage from the driving gear 12 upward. At this time, the motor 8 only drives the water spray pipe 11 to rotate. When the height is adjusted, open the water tank 21 to spray water.
