Abstract
An automated building washing device generally includes a spray bar assembly coupled to a window washing swing stage. The spray bar assembly is horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while spray heads rotate so that a relatively large portion of building surface can be quickly cleaned. The spray bar assembly includes a hollow rotating bar and spray heads inside of a shroud so that the bar can rotate as water or cleaning solution is sprayed onto the building surface for cleaning.
Claims20
An automated building washing apparatus, comprising:
- a swing stage;
- a track coupled to the swing stage, the track movable in a horizontal axis along the swing stage parallel to a surface to be washed;
- and
- a spray bar assembly coupled to the track such that the spray bar assembly can move along the horizontal axis across the surface to be washed, the spray bar assembly comprising,
- a circular shroud defining an enclosure with an open side that faces the surface to be washed;
- a hollow bar rotationally disposed about its midpoint inside of the circular shroud, wherein the hollow bar rotates about an axis that is perpendicular to a direction that the track moves;
- a first spray head disposed at a first end of the hollow bar;
- and
- a second spray head disposed at a second end of the spray bar,
- wherein the first and second spray heads are configured to spray a cleaning solution or water towards the surface to be washed.
An automated building washing assembly that can be retrofitted to a swing stage, the automated building washing assembly comprising:
- a track that can be coupled to the swing stage;
- and
- a spray bar assembly coupled to the track such that the spray bar assembly can move horizontally between opposing longitudinal ends of the track, the spray bar assembly comprising,
- a circular shroud defining an enclosure with an open side that faces outward from the swing stage and towards a surface to be washed;
- a hollow bar rotationally disposed about its midpoint inside of the circular shroud, wherein the hollow bar rotates about an axis that is perpendicular to a direction that the spray bar assembly moves along the track;
- a first spray head disposed at a first end of the hollow bar;
- and
- a second spray head disposed at a second end of the spray bar,
- wherein the first and second spray heads are configured to spray a cleaning solution or water towards the surface to be washed.
A method of washing a building, comprising attaching a track to a swing stage;
- coupling a spray bar assembly to the track;
- rotating a hollow bar and a pair of spray heads about an axis normal to a surface of the building to be washed while linearly moving the spray bar assembly between longitudinal ends of the swing stage;
- and
- changing a vertical height of a swing stage while linearly moving the spray bar assembly between longitudinal ends of the swing stage.
