Description

Building facade work platform, contact surface treatment device and non-contact surface treatment device based on building facade work platform Technical Field The present invention relates to a high-rise working apparatus, and more particularly, to a building facade working platform capable of carrying different working units for processing a facade of a building based on a rope system. In particular to a contact type surface treatment device based on the building facade working platform and a non-contact type surface treatment device based on the building working platform. Background The maintenance of the facade of high-rise and super high-rise buildings is a key link in the operation of the buildings. Such maintenance may involve, in addition to cleaning, exterior facade paint refurbishment, exterior thermal insulation spraying, exterior facade stone construction, exterior facade hollowing detection and maintenance, and the like. Taking the daily cleaning of the most common glass curtain wall as an example, the aim of cleaning the glass curtain wall is not only to beautify the environment and keep the appearance of the building clean, but also to remove pollutants, protect glass and sealant from being corroded by acid rain or dust, and prolong the service life of the curtain wall. The common operation modes at present mainly comprise manual cleaning, and a building maintenance unit (BMU-Building Maintenance Unit) for operating by means of a window cleaning machine or a hanging basket, and a window cleaning robot with higher automation degree. because the cleaning of the glass curtain wall of the building is a high-risk and high-professional operation, the manual cleaning mode is more flexible and can adapt to various complex outer elevation structures, but the high-altitude operation is greatly influenced by weather factors such as outdoor temperature, humidity, wind speed and the like besides the skills and experience of operators, and belongs to the high-altitude operation with extremely high safety risk. It is expected that in this application scenario, the manual cleaning will gradually decrease the specific gravity until it is eliminated. Different from the window cleaning machine or hanging basket mode, the special window cleaning machine or hanging basket installed on a roof is mainly used as a manned platform, workers stand on the platform to operate cleaning tools, the safety is higher than that of rope operation, the stability is good, more tools and equipment can be carried, the window cleaning machine or hanging basket mode is suitable for super high-rise buildings, and meanwhile, the window cleaning machine or hanging basket mode is a working scheme for cleaning glass curtain walls by applying more at present. But its drawbacks are also evident, firstly, its extremely high cost, which can significantly increase the maintenance costs of the building. Secondly, even though the operator stands on a platform such as a hanging basket, the platform is still exposed to high altitude, strong wind and extreme weather, and risks such as object falling, accidental operation errors of the operator or sudden diseases exist. Moreover, the professional window cleaning machine or hanging basket or the like can overlap the weight of operators by self weight, so that when lifting control is performed, whether the lifting machine is arranged at the hanging basket end or the lifting machine is arranged on the roof, the structural bearing capacity of the roof of the building is strictly required, and if translation factors are considered, the space and layout of the roof of the building are strictly limited. It follows that there is still room for improvement in current BMU or basket solutions. The window cleaning robot system is a more intelligent scheme proposed by some manufacturers at present, and different from the two schemes, the scheme mostly uses a negative pressure adsorption mode, so that the intelligent window cleaning robot with special design is attached to a glass curtain wall for cleaning operation, and the process is realized only by a remote control mode without the need of actual high-altitude operation of operators. Compared with the former two modes, the glass curtain wall can obviously improve personnel safety, is only suitable for the operation of the outer surface of the glass curtain wall, has the problems that equipment cost is relatively high, the negative pressure adsorption characteristic determines that the glass surface has high requirements on flatness, and in addition, compared with manual treatment, the glass curtain wall has unsatisfactory cleaning capability, especially has relatively weak capability of treating stubborn stains with strong adhesiveness. It follows that the prior art has more or less drawbacks when working on facades of high-rise buildings, and that improvements are needed.
