Curtain wall cleaning, beautifying and practical training intelligent device for student practice

Technical Field

The invention belongs to the field of curtain wall cleaning, and particularly relates to a curtain wall cleaning, beautifying and practical training intelligent device for student practice.

Background

The outer wall of a high-rise building generates dirt and weathering due to the perennial exposure to the sun, the wind and the rain, the pollution of harmful gas, oil smoke and the like in the atmosphere and the erosion of chemical reaction, thereby not only influencing the standard and the market appearance of the building, but also damaging the building. Therefore, the cleaning of the outer wall of the building not only beautifies the environment, but also plays a role in protecting the building.

The cleaning of the building outer wall generally adopts a seat plate type single-person hanger suspension operation mode or a hanging basket mode. The suspension operation mode of the seat plate type single-person sling is that workers use a lifting plate (rope) to slide down to a designated position to carry out construction operation. The construction mode is convenient and flexible, occupies less resources and can reduce the influence on the daily work and life of the owners to the maximum extent. The hanging basket mode is that a hanging basket is erected on the roof to convey workers to a specified position for construction operation, and the construction mode is low in cleaning efficiency and high in cost. Because the two modes are both operated manually, the cleaning quality is difficult to ensure, and greater potential safety hazard exists due to high-altitude operation.

Based on the consideration of safety and efficiency, sometimes, an automatic cleaning mode which can replace manual work and is simple in execution structure design is adopted, and sewage for cleaning the wall surface can flow down along the curtain wall and form stream stains on the curtain wall in the cleaning process, so that the cleaning effect and the cleaning quality are influenced.

The invention designs a curtain wall cleaning, beautifying and practical training intelligent device for practical operation of students by utilizing a six-joint mechanical arm in the prior art so as to achieve the aim of efficiently cleaning curtain walls with high quality.
