Description

TECHNICAL FIELD

[0001] The utility model relates to spraying technical field, concretely is a pipeline spraying device of spraying pipe height adjustable. BACKGROUND

[0002] Fire overhead pipeline is an indispensable part of modern fire fighting system, and is widely used in shopping malls, public buildings and industrial buildings. It is usually made of corrosion-resistant, high-temperature-resistant and pressure-resistant materials such as stainless steel or galvanized steel to ensure that the fire water can maintain sufficient flow and pressure in emergency. Fire overhead pipeline has many forms such as water diversion, spraying, fire extinguishing and spraying. Water diversion overhead pipeline is used to transport fire water; spraying overhead pipeline sprays water mist to the fire scene through spraying head; fire extinguishing overhead pipeline uses high-pressure water mist jet to extinguish fire; spraying overhead pipeline sprays water mist to the fire site to quickly and effectively suppress the spread of fire.

[0003] After the installation of fire overhead pipeline is successfully completed, in order to facilitate the distinction and management, the surface of the pipeline must be properly marked. These marks usually include color coding, text description or other identification to ensure that users can easily identify different types of fire pipeline. Because the layout of fire overhead pipeline is complex and has ups and downs, workers often need to use various auxiliary tools such as ladder to safely climb to a higher position for spraying work. However, this traditional work method is relatively low in efficiency, not only time-consuming and laborious, but also has certain safety risks in high-altitude work. UTILITY MODEL CONTENT

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] When the first clutch is in the engaged state, the driving motor can drive the driving shaft to rotate. Then, the rotation of the driving shaft is transmitted to the transmission shaft, so that the transmission shaft rotates. The rotation of the transmission shaft further drives the driving gear to rotate, thereby driving the driving rack to move in the vertical direction. The movement of the rack finally realizes the up-down displacement of the telescopic pipe, so as to adjust the height of the spray head on the conveying pipeline, so as to accurately spray the pipelines of different heights.

[0014] When the second clutch is in the engaged state, the operation of the conveying pump can be driven by the operation of the driving motor. With the start of the conveying pump, the paint stored in the storage tank begins to be sprayed out through the spray head. The paint sprayed out through the spray head passes through the leakage plate block, so that the required mark can be quickly painted on the surface of the pipeline to be coated.
