Definitions
- An abrasive cleaning apparatus including an adjustable nozzle support means having a first and second positioning means to permit movement of a plurality of nozzle means in a first and second plane respectively.
- Sand blasting of surfaces cleaned preparatory to painting and simply cleaning in the case of stone or brick walls is a common practice. Generally, this is accomplished by an operator positioned on a scaffold or other suitable support manually manipulates at least one discharge nozzle. Obviously, the presence of the operator in the work zone makes this an extremely dirty and hazardous occupation. Moreover, the limited volume of sand blasted against the surface by a single nozzle is very inefficient.
- abrasive blast apparatus particularly used for large surface areas, may employ multiple rather than a single blast nozzle.
- the obvious advantage of this being a greatly increased blast pattern. Due to the increased weight and speed of operation, these nozzles are often mounted on movable carriages or platforms on which the operator rides. The platform is movable laterally and vertically along the area to be cleaned which results in significant labor saving devices.
- multi-nozzle heads are of a type in which the sand and air are delivered and mixed in a common reservoir from which jet streams are propelled simultaneously from the nozzles all of which communicate directly with the reservoir.
- the operator may be provided with two separate nozzles each having its own supply lines.
- individual control of the nozzles is lacking to the extent that the blast stream from one nozzle cannot be cut off independently of the other.
- Such independent manipulations of the blast from the different nozzles is desirable in situations involving spots or areas which present difficult cleaning problems. The blast from one nozzle must work on this different area for a prolonged period, during which time and other blasts will be cutting away injuriously at the clean metal or surrounding areas.
- the abrasive cleaning apparatus comprises a base means for mounting the abrasive cleaning apparatus on the mobile chassis, an adjustable nozzle support means to operatively support a plurality of nozzle means thereon and interconnecting boom means coupled between the base means and the adjustable nozzle support means.
- the base means comprises a base plate including an attachment means to detachably attach the abrasive cleaning apparatus to the mobile chassis.
- the base plate and interconnecting boom means cooperatively from a first adjustment means to adjust the rotational position of the adjustable nozzle support means relative to the base plate.
- the adjustable nozzle support means includes a first and second positioning means to permit movement of the plurality of nozzle means in a first and second plane respectively.
- the first positioning means comprises a substantially rectangular frame pivotally attached to the outer portion of the interconnecting boom means.
- the second positioning means comprises a mounting frame pivotally attached to the outer end of the first positioning means to support the plurality of nozzle means.
- the interconnecting boom means comprises a first and second boom element arranged in telescoping relation relative to each other to adjust the linear position of the adjustable nozzle support means relative to the base plate.
- the operator stands on the platform adjacent the adjustable nozzle support means.
- the plurality of nozzle means is coupled to a remote supply source through a conduit means.
- the remote supply source may comprise a sand hopper which also incorporates an appropriate compressed air supply to forcefully transport and drive the abrasive from the nozzles.
- a supply of compressed air is directed along with the sand into flexible sand conduits for transporting the sand through these conduits.
- compressed air may also be directed into flexible air conduits. This separate supply of air under pressure eventually being directed into a mixing reservoir within the blast nozzles to and against the work.
- the manner in which the air and sand is mixed in the nozzle is of no particular concern.
- the nozzle structure of the present mechanism itself can be on any appropriate conventional configuration.
- the interconnecting boom means is rotated relative to the base plate to the desired position.
- the second boom element is then adjusted in telescoping relation relative to the first boom element to the desired position.
- the operator then cleans the work surface, manipulating the adjustable nozzle support means by pivoting the first and second positioning means in the first and second planes relative to the work surface and base plate. In this manner, the operator is able to clean an enlarged work surface through the use of multiple nozzles without the necessity of supporting the nozzles or air and abrasive supply conduits.
- the mobile chassis is then moved to an adjacent work surface until the entire area is cleaned.
- FIG. 1 is a perspective view of the abrasive cleaning apparatus
- FIG. 2 is a side view of the abrasive cleaning apparatus
- FIG. 3 is a top view of the abrasive cleaning apparatus.
- the present invention comprises an abrasive cleaning apparatus generally indicated as 10 for cleaning large work surfaces.
- the abrasive cleaning apparatus 10 comprises a base means 12, interconnecting boom means 14 and adjustable nozzle support means 16.
- the base means 12 comprises a substantially flat hemispherically shaped base plate 18 having a plurality of apertures 20 formed about the periphery thereof.
- the base plate 18 is detachably attached to an operator cage 22 mounted on a mobile platform or other suitable support means (not shown) by suitable attachment means (not shown).
- the base means 12 and interconnecting boom means 14 cooperatively form a first adjustment means to permit rotational adjustment of the adjustable nozzle support means 16 relative to the operator cage 22 and base means 12 as shown by arrow a--a.
- the interconnecting boom means 14 comprises first boom element 24, second boom element 26 and coupling means 28.
- the first boom element 24 is pivotably attached to base plate 18 by first fastening means 30 and further includes an engaging means such as a bolt/nut combination 32.
- Engaging means 32 cooperates with apertures 20 to permit adjustment of the adjustable nozzle support means 16 as previously described.
- the second boom element 26 is disposed in telescoping relationship to the first boom element 24.
- the coupling means 28 comprises a slide element 34, bracket elements 36 and fastening means 39.
- the fastening means is loosened such that the second boom element 26 may be telescoping.Iadd.ly .Iaddend.moved linearally relative to the first interconnecting boom element 24 in the direction as shown by arrow b--b.
- This telescoping arrangement comprises a second adjustment means permitting adjustment of the adjustable nozzle support means 16 relative to the operating cage 22 and the base plate 18 as shown by arrow b--b.
- the adjustable nozzle support means 16 comprises a first and second positioning means 38 and 40 respectively to permit movement of the plurality of nozzle means generally indicated as 42 in a first and second plane respectively as shown by arrows c--c and d--d respectively.
- the first positioning means 38 comprises a first and second member 44 and 46 respectively .[.held fixed spaced relationship by end members 49 and.]. .Iadd.with mounting frame 60 pivoted at .Iaddend.50.
- the first positioning means 38 further includes .Iadd.boom .Iaddend.attachment .[.means 52 comprising.]. .Iadd.plate 48, .Iaddend.tubular element 56 and securing means 58.
- the entire adjustable nozzle support means 16 is pivotably mounted on second interconnecting element 38 by tubular element 56 extending through element 28 and secured thereto by securing means 58 which may comprise a cotter key or nut..].
- the second positioning means 40 comprises .[.a.]. .Iadd.the .Iaddend.mounting frame 60 and handle 62 as best shown in FIGS. 1 and 2.
- the mounting frame 60 is pivotally mounted .[.on the outer end member.]. .Iadd.at .Iaddend.50 to .[.support the plurality of nozzle means 42.]. members .Iadd.44 and 46.Iaddend..
- the mounting frame 60 includes a plurality of apertures 64 formed therein to receive a corresponding plurality of nozzles 66.
