Flying dust suppression device for construction site

Abstract

The invention provides a dust suppression device for a construction site, and relates to the field of environment-friendly construction. Comprising a tower crane, a water tank, a water supply pipeline and a water outlet pipeline, the tower crane comprises a tower body and a tower arm, the water tank is installed at the balance weight end of the tower arm, one end of the water supply pipeline is in butt joint with an external water source, and the other end of the water supply pipeline extends to the tower arm along the tower body and communicates with the water tank; a plurality of first nozzles are sequentially arranged on the water outlet pipeline in the axial direction; the multiple expansion pipes are rotationally connected with the tower arm, one ends of the expansion pipes communicate with the water outlet pipeline, and the other ends and the circumferential directions of the expansion pipes are all connected with second nozzles. Aiming at the problems that a water supply pipeline of a spray dust suppression device carried by the existing tower crane is inconvenient to arrange and the operation range is difficult to meet the requirement, a tower arm pipe and a tower body standard section limb column are used as main pipelines for conveying water flow and are matched with a rotating joint, so that the problem of winding interference caused by externally hanging a water pipe on the tower crane is avoided.

Description

technical field [0001] The invention relates to the field of environmental protection construction, in particular to a dust suppression device at a construction site. Background technique [0002] Tower cranes are currently commonly used construction machinery in building construction, especially in the construction process of high-rise buildings, to lift various materials used in building construction to high-rise buildings, but during the construction process, there is a lot of dust on the construction site , the generated dust is easy to diffuse and cause environmental pollution, and the diffused dust will have adverse effects on normal construction and surrounding residential areas.

Problems solved by technology

[0002] Tower cranes are currently commonly used construction machinery in building construction, especially in the construction process of high-rise buildings, to lift various materials used in building construction to high-rise buildings, but during the construction process, there is a lot of dust on the construction site , the generated dust is easy to diffuse and cause environmental pollution, and the diffused dust will have adverse effects on normal construction and surrounding residential areas

[0003] At present, there are dust suppression equipment realized by using the high coverage characteristics of the tower crane, such as tower crane spray equipment, tower crane spray equipment, etc., by installing nozzles on the tower crane arm and diverting the water flow to the high place of the tower crane through pipelines The position of the nozzle enables the water flow to spray water mist through the nozzle, and the swing of the tower arm is used to expand the scope of action and improve the dust suppression effect; however, there are certain disadvantages in the way of using the tower crane to carry the spray nozzle, and the water supply needs to rely on the water pipe , the water pipes arranged on the tower crane tower will affect the operation of the tower crane and are prone to entanglement; in addition, due to the limited width of the tower crane, although the traditional method of inclined nozzle arrangement can increase the coverage to a certain extent, its coverage The width is still limited, and it is impossible to cover some large work areas to suppress dust; on the other hand, after installing water pipes and nozzles, the load on the tower arm increases, and the strength of the original tower arm cannot meet the normal lifting requirements of the tower arm
