Abstract:
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.
