Slide carriage mechanism of window cleaning device

Abstract

The invention provides a slide carriage mechanism of a window cleaning device, which is connected with a cleaning head and realizes cleaning by shifting the cleaning head. The slide carriage mechanism comprises a slide carriage which is connected with the cleaning head, a lead rail and a driving device which is used for driving the slide carriage to move along the lead rail; wherein, the lead rail extends along the up and down direction; a driving pulley and a driven pulley are respectively arranged on the top and bottom ends of the lead rail, a cog belt is wound up between the two pulleys; the slide carriage comprises a slide carriage body and an axis of rotation, the slide carriage body can move along the lead rail, one end of the axis of rotation is connected with the slide carriage body while the other end thereof is connected with the cleaning head. In the invention, the cog belt moves around the two pulleys and ensures the slide carriage body to move along the lead rail, the cog belt drives the axis of rotation to rotate, then the cleaning head is driven to rotate together with the axis of rotation to carry out cleaning. The slide carriage mechanism has the advantages of accurate positioning, simple structure and low cost.

Description

technical field [0001] The invention relates to a sliding seat mechanism of a window cleaning device. 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 mechanism is that the sliding seat is arranged in the groove guide rail, and the transmission mechanis...

AI Technical Summary

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.
