초록 ▼

Briefly, disclosed is an ultra high pressure blasting head for a mobile marking removal system. The blasting head includes a hydraulic motor that is constructed and arranged for direct connection to a spray bar for controlled rotation thereof. The output shaft of the hydraulic motor is constructed to be hollow or tubular so that the ultra high pressure water can be supplied to the spray bar through the output shaft. The spray head assembly is particularly suited for mobile systems utilized to remove markings and/or coatings from surfaces with high or ultra high pressure liquid.

1. A cleaning device for discharging fluid under high pressure towards a surface to remove coatings therefrom comprising: a blast head, said blast head having at least one nozzle constructed and arranged to deliver a second high pressure fluid toward a surface;said blast head having a shroud, said shroud having a top, sides and an open bottom, said top of said shroud being connected to a flange adapter portion of a hydraulic motor,said hydraulic motor mounted on said shroud to provide horizontal and vertical thrust support to said shroud, said hydraulic motor having a first fluid input and a first fluid output for causing rotation of a tubular spindle within said hydraulic motor, said tubular spindle having a driving surface on an outer surface of said tubular spindle to cause rotation thereof in response to a pressure differential provided by said driving surface cooperating with a first pressurized fluid, said driving surface being a gear surface, said gear surface intermeshing and causing rotation of an idler gear in response to rotation of said gear surface, said spindle being tubular including a conduit passing through said hydraulic motor, said tubular spindle having a spindle inlet positioned on a first side of said hydraulic motor and a spindle outlet positioned on a second side of said hydraulic motor for passage of a second pressurized fluid through said tubular spindle;a swivel inlet fluidly connected to said second pressurized fluid for delivery of said second high pressure fluid to a swivel outlet,said swivel outlet fluidly connected to said spindle inlet, said spindle outlet being in fluid communication with said at least one nozzle;whereby said second high pressure fluid passes through said tubular spindle to said at least one nozzle for impingement against a surface to be cleaned. 2. The cleaning device of claim 1 including a spray bar in fluid communication with said swivel outlet; a plurality of said nozzles mounted on said spray bar and in fluid communication therewith, whereby rotation of said spindle causes rotation of said spray bar and said plurality of nozzles deliver said second pressurized fluid to a surface to remove coatings thereon. 3. The cleaning device of claim 2 wherein said spray bar extends within said shroud from adjacent one side of said shroud to adjacent another side of said shroud. 4. The cleaning device of claim 1 including a plurality of wheels connected to and supporting said blast head a predetermined distance from the surface. 5. The cleaning device of claim 1 wherein said second high pressure fluid in between substantially 25,000 and 40,000 pounds per square inch. 6. The cleaning device of claim 1 wherein said second high pressure fluid is water. 7. The cleaning device of claim 1 including at least one pair of bushing seals mounted on said blast head, said at least one pair of bushing seals being located both above and below said hydraulic motor. 8. The cleaning device of claim 7 wherein said bushing seals are thrust bearings. 9. The cleaning device of claim 1 wherein said driving surface is a multi-toothed gear mounted around said spindle, said multi-toothed gear having multiple said gear surfaces for driving said tubular spindle.
