Window cleaning device

Abstract

The invention relates to a window cleaning device, which comprises a cleaning head, a slide seat mechanism and a control and drive device; wherein, the slide seat mechanism is connected with the cleaning head to ensure the cleaning head to clean the windows in a movable way; the control and drive device is used for controlling and driving the slide seat mechanism; the slide seat mechanism comprises a longitudinal slide seat, a longitudinal guild way, a latitudinal slide seat and a latitudinal guild way. A longitudinal driving motor of the control and drive device actuates a driving pulley which is connected with the longitudinal driving motor to rotate so that a cog belt can move around the driving pulley and a driven pulley to spur the longitudinal slide seat to move along the longitudinal guild way as well as spur a pivot pulley to rotate together with a rotation axis; the latitudinal driving motor actuates the latitudinal slide seat to move along the latitudinal guild way so as to drive the longitudinal guild way to move in latitudinal direction so that free move in both longitudinal and latitudinal directions of the window cleaning device can be realized.

Description

technical field [0001] The invention relates to a window cleaning device, in particular to a window cleaning device capable of automatically and accurately wiping high-altitude glass, walls and the like. Background technique [0002] With the continuous increase of high-rise buildings, the cleaning of glass windows and glass curtain walls or colored curtain walls of high-rise buildings has become a big problem. In the past, it was common to use hanging baskets to carry cleaning workers for cleaning. This method has low labor efficiency, dangerous working environment and high cleaning costs. As an improvement, there are now automatic window cleaning devices driven by guide rails. [0003] As an automatic window cleaning device, the slide mechanism that moves the wiping head up and down is particularly important. Whether the slide mechanism slides smoothly or not and the position accuracy of the control directly leads to the cleanliness of the window. The usual sliding seat ...

Problems solved by technology

It is guided by embedded groove guide rail. Since the groove is placed outdoors, once it is blocked by foreign matter scraped in, the entire slide mechanism needs to be removed for cleaning. Moreover, the embedded assembly structure requires the cooperation of the slide seat and the guide rail. The precision is very high, that is, the machining accuracy of the two is required to be very high. If the gap is too large, it will easily lead to loosening and unstable positioning.

Moreover, due to the rotation of the rotating shaft of the wiping disk, it is also easy to cause the sliding seat to swing relative to the guide rail.

And, owing to adopt the transmission mechanism that is made up of chain, sprocket wheel, worm gear and electric motor, chain, sprocket wheel, worm gear are mostly made of iron, and weight is big, is difficult to be located at too high place.
