Definitions

  • ABSTRACT This invention relates to a fixture for a blast cleaning machine.
  • the fixture is portable and adapted to be positioned on a metallic surface and secured thereto by electromagnets.
  • a blast cleaning device is attached to the fixture, on a movable carriage, for movement along the fixture under control of a motor operated hoist. When cleaning is finished, the fixture is released and moved to the next segment of the surface to be cleaned.
  • a linkage assembly assures that the blast cleaning device is maintained in intimate contact with the surface to be cleaned, and a set of opposed rollers assures that the blast cleaning device moves only in the intended direction.
  • This invention relates to a fixture for supporting surface finishing machines which utilize particulate material for cleaning or resurfacing. By causing the particulate material to strike the surface to be treated at sufficiently high velocities and in sufficient numbers, metal and other surfaces which require periodic maintainance can be cleaned or otherwise treated.
  • a particularly desirable form of apparatus for performing this task is one which is portable so that it may be utilized in circumstances where it would not be feasible to bring the surface to the machine for treatment.
  • a specific use for such a portable apparatus is the cleaning of a vertical or other non-horizontal surface such as a wall, a platform or the like.
  • Portable machines capable of performing abrasive blasting operations on such non-horizontal surfaces are known, for example, U.S. Pat. No. 3,034,262 to Pawlson, and my copending application, Ser. No. 443,389.
  • FIG. 1 is a front view of the fixture according to the present invention having a blast machine mounted thereon;
  • FIG. 2 is an enlarged front view of the fixture of FIG. 1.
  • the fixture includes a frame composed of two longitudinal members 12.
  • the members 12 are preferably hollow and have a rectangular cross section. Such members are desirably 20 to 30 or more feet in length.
  • the frame thus constituted by the longitudinal and transverse members forms a rectangular frame wherein the longitudinal members are desirably of a greater length than the transverse members.
  • the four electromagnets are adapted to be energized by passing an electric current therethrough, in a manner well known by means of a wiring harness not shown. Energizing the electromagnets is effective for securing the rectangular framework to a ferromagnetic surface such as a wall, deck or other surface 20. Due to the intimate contact of the electromagnets against the surface, the fixture is rigidly secured in place when the electromagnets are energized.
  • the carriage 22 is mounted to the frame for linear movement, i.e., vertical movement in the figure along the length of the longitudinal members 12. As best shown in FIG. 2, movement of the carriage in any other direction is prevented by a plurality of opposed rollers.
  • the rollers are mounted to the carriage but on different sides of the longitudinal member 12. For example, rollers 26 and 28 are mounted on the side opposite the roller 30. Likewise, rollers 32 and 34 are mounted on the side opposite the roller 36. Since all of the rollers are adapted for vertical movement, the carriage can be moved up and down but cannot be moved sideways or angularly.
  • a parallelogram swing linkage assembly is provided for mounting a blasting machine to the carriage 22.
  • the linkage assembly includes a pair of forward links 40 and a pair of rear links 42. As best shown in FIG. 2, the upper end of the forward link 40 is connected to the carriage 22 while the lower end of the link 40 is at tached to the blasting machine housing 44.
  • the blasting machine shown is of the type manufactured by Wheelabrator-Frye, Inc. of Mishawaka, Indiana. These devices are airless centrifugal blasting wheels and include a throwing wheel contained within a housing, such as housing 44. The wheel is driven by a motor 46 at high velocity for projecting particulate material fed through a controlled rate valve 48 onto a surface. The material fed through the valve 48 is supplied from a feed hopper 49.
  • the rear links 42 are connected to the carriage at their upper ends while their lower ends are connected to the feed hopper 49. Connecting the blasting machine to the carriage through this linkage permits small movements normal to the direction of travel, i.e., perpendicular to the surface being treated. This move nent is desirable in order to permit the blast machine to follow surface irregularities or imperfections without catching thereon.
  • the blast machine utilizes a protective seal 50 adapted to intimately engage the surface for preventing the abrasive blast from escaping outside the blast area, causing a loss of particulate and danger to personnel. Because of the necessity for keeping the seal in intimate contact with the wall, and at the same time providing for some give,” it is desirable to provide means for urging and maintaining the blast cleaning device against the surface 20.
  • a pair of linear actuators 52 mounted to the carriage are provided. Typically these actuators are hydraulic or pneumatic cylinders effective for pushing the swing linkage towards the surface to be cleaned.
  • a powered hoist is provided on the fixturing device.
  • the hoist includes a motor 60 and a speed reducing gearbox 62 driving a sprocket wheel 64.
  • a corresponding sprocket wheel 66 is disposed at the other end of the longitudinal member 12.
  • Entrained about the sprocket wheels 64 and 66 is a roller chain 68 adapted to mate with the sprockets on the sprocket wheels.
  • the ends of the roller chain are connected to the carriage by connectors 70 and 72.
  • operation of the motor is effective for propelling the carriage up or down the longitudinal frame members 12.
  • the blast cleaning device Prior to use, the blast cleaning device is mounted to the carriage of the fixture by attachment to the front and rear links. The fixture is then lifted by a crane, forklift truck or other device and positioned against the surface to be cleaned. When the fixture is in the approximate position desired, preferably with the members 12 vertical, the electromagnets are energized, causing the fixturing device to grip the surface 20 to securely hold itself and the blast cleaning device thereon.
  • the power hoist mounted on the fixturing device is then utilized to position the carriage at the top or bottom of its travel path and the blast cleaning device is switched on.
  • the hoist is then utilized for moving the carriage mounted blast cleaning device along the length of the longitudinal members 12.
  • the rate of movement of the blast cleaning device is controlled by the speed of the motor, and this rate is optimized to obtain the desired cleaning characteristics for the particular surface being treated.
  • the linear actuators 52 and the linkage maintain a constant pressure on the blast machine to keep the seal parallel and in intimate contact with the surface 20.
  • the linkage assures that the seal face remains parallel and in contact with the treated surface even when passing across surface irregularities such as seam welds.
  • the blast machine After the carriage has traveled the full length of the longitudinal members, the blast machine will have cleaned a vertical path on the treated surface.
  • the fixture is again supported by the forklift truck, crane or other device and the electromagnets are deenergized.
  • the fixture device is repositioned to an adjacent area of the surface 20 and the sequence is repeated until the entire surface has been cleaned.
  • a portable device for movably securing a blast cleaning machine to a ferromagnetic surface comprising:
  • a portable device according to claim 1 wherein said means for linking includes:
  • a swing linkage adapted to permit small movements of said blast cleaning device relative to said carriage in a direction normal to the direction of carriage movement
  • actuator means for urging and maintaining the blast cleaning machine in contact with said surface.
  • said frame includes:
  • said carriage includes a plurality of rollers adapted to engage said frame to permit linear movement along its length but to restrict movement in any other direction.
  • the device according to claim 1 further including a motor driven hoist connected to said carriage for selectively moving said carriage on said frame.
  • the device according to claim 6 further including a motor driven hoist connected to said carriage for selectively moving said carriage on said frame.
  • a portable device for movably securing a blast cleaning machine to a ferromagnetic surface comprisa. a rectangular frame comprising two longitudinal members and two transverse members connecting said longitudinal members at their ends;
  • electromagnetic means mounted on legs attached to said frame at the ends of the longitudinal members for releasably securing said frame to said surface;
  • a carriage movable on said frame and including a plurality of rollers adapted to engage said frame to linkage means includes a swing linkage adapted to permit smallmovements of said blast cleaning device in a direction normal to the direction of carriage movement and actuator means for urging and maintaining the blast cleaning machine in contact with said surface.
