This potentially billion dollar market of the glass curtain wall cleaning has always depended on three ways of cleaning: the familiar centipede man, with a rope, a plate and a bucket; Through lifting platform, hanging basket and other tools to carry the cleaner cleaning; The roof sling rail system aims the window splicer at the window for cleaning. The first two are low in efficiency, high in labor intensity and high in danger. The second is high in operation cost. The third kind of initial investment is high, but also need to take the window cleaning system into account when building, so it is not realistic.
At present, the most common one on the market is manual cleaning. Aerial work is a high-risk occupation with high premiums and many people without insurance, which means that once an accident occurs, it is difficult to guarantee their rights and interests. Cleaning service companies and property owners may also bear corresponding responsibilities.
There are no publicly available data on the incidence of accidents at height. However, there are media reports that tens of thousands of high-altitude work accidents occur in China every year, among which the death rate is as high as 80%. As the post-1990 generation has become the main labor force, as a high-risk industry of the curtain wall construction, the aerial work industry will also face recruitment problems. Under the dual effects of ultra-high work intensity and risk, the employment gap in high-risk occupations is expanding year by year, and it is an inevitable trend to replace human labor with machines.
However, it is not easy to develop such a high-altitude curtain wall cleaning robot that can replace manual work. From the overall design requirements, yes
Meet the following functions:
1. Adsorption function
2. Mobile function
3. Obstacle crossing function
4. Cleaning function
Among them, the difficulty of mobile function and obstacle crossing function is not low. The difficulty of mobile function is that the machine should be able to adapt to a variety of wall materials such as curtain glass window, metal and powdery wall, and be able to walk on curved surface and control posture. The obstacle crossing function requires the machine to be able to cross the window frame and other obstacles in the process of moving, and some of them also need to realize the transformation from the ground to the wall and from the wall to the wall. Walking on curved wall is still a difficult problem to solve.
To solve these problems, there are two main solutions at present. One is to develop a universal machine, and the other is to develop different robots for different materials. The former is more commercially feasible, while the latter is technically easier to implement.
In fact, there have been foreign researches on high-altitude curtain wall cleaning robot, but they have not been widely promoted.
