Abstract:Based on automation, intelligent, low cost, safe and effective ideas for automatic cleaning machine running mechanism of glass curtain wall of highrise building, a cleaning mechanism, a steering mechanism and security mechanism of three dimensional (3D) structure was designed, at the same time using SolidWorks software in the Simulation plugin, automatic cleaning machine for floor of the largest stress of finite element analysis (FEA) was carried out. The automatic cleaning machine could be reliably adsorped in the outer surface of the glass curtain wall vertically to realize the automatic walking, turning, clean, safe and reliable. It can effectively solve the problem of big risk of manual cleaning of glass curtain wall of highrise buildings, the defects of low efficiency, and greatly improve labour efficiency.
