Description

Technical Field

[0001] The utility model relates to the technical field of building exterior wall construction, in particular to an exterior wall spraying device for high-rise buildings. Background Art

[0002] With the continuous development of the urbanization process, the number of high-rise buildings in cities is increasing. In the construction of high-rise buildings, it is necessary to spray or perform other decoration work on the outer surface of the building. These spraying and decoration works not only directly affect the appearance of the building, but also greatly affect the overall appearance of the city. At present, the spraying work of high-rise buildings still adopts traditional process methods, all of which are completed manually. In the construction of the exterior walls of high-rise and super-high-rise buildings, manual spraying is not only inefficient, but also has a poor working environment. Workers often encounter many adverse factors such as high temperature and strong wind, which seriously affect the spraying quality and even pose a threat to the health and life safety of workers. Therefore, it is very necessary to design a spraying device for high-rise buildings to replace workers to complete the spraying operation.

[0003] After retrieval, the patent with the application number CN202211614843.1 discloses an exterior wall spraying device for high-rise buildings. Multiple manipulators on the rope climber drive suction cups so that the working platform can be relatively stable with the high-rise building. The gap between the working platform and the wall is filled with a curtain to prevent the splashing of paint during spraying from causing the paint to drip to the bottom of the building. The spraying mechanism sprays the paint in the paint processing device onto the wall through a discharge pipe. The horizontal moving device and the lifting device enable the spraying mechanism to achieve multi-directional spraying. After spraying, the scraping device can evenly scrape the sprayed wall surface. After scraping, the paint after spraying can be quickly dried by the air drying device, so that the paint after spraying can quickly bond with the wall.

[0004] However, after the above device sprays the paint onto the wall surface, the excess paint will flow down along the wall surface. If it is not collected and removed, due to the uneven distribution of the paint thickness after subsequent spraying, phenomena such as streaks will occur, affecting the construction quality.

[0005] Therefore, we propose an exterior wall spraying device for high-rise buildings that can achieve a simpler structure and complete the technical effect of automatic spraying of the high-rise outer wall. Summary of the Utility Model
