Definitions

  • the present invention relates to a device for blasting large workpieces located within a work area with at least one blasting unit connected by a blasting agent hose to a blasting agent source.
  • Castings from large machine construction, large containers, locomotive and railway structures are blasted by hand in a hall that serves as a blasting house. Due to the size, complexity and small number of such parts, treatment in automatic systems is practically impossible.
  • Hand blasting requires some basic framework conditions and still brings with it considerable problems.
  • the blasting house where this work is carried out must be equipped with a blasting agent return system integrated in the floor.
  • an air cleaning system with a very large air throughput is required to remove the dust, as well as a corresponding air supply system with air heating for winter operation.
  • very powerful lighting fixtures are required throughout the room.
  • the operating personnel working in a blasting house must be equipped with protective suit and hard hat with external air supply, as well as special gloves.
  • the device according to the invention aims at reducing the effort for the blasting house, humanizing the working conditions and, in connection therewith, a substantial increase in work performance
  • each unit is mounted on a passenger cabin with a lockable access opening by means of a universal joint and by an actuation arranged in the cabin element can be pivoted on all sides and the effective range of the nozzle can be observed through a window opening, and that the cabin is mounted horizontally and vertically displaceable in at least part of the working range.
  • the invention also allows workpieces with large, vertical dimensions to be processed in a rational manner without a ladder, pedestals or lifting devices. It is preferably provided that the passenger cabin can be rotated about a vertical axis. This means that you can work practically around a workpiece. It is also possible to maneuver the device even in difficult places so that optimal work is possible.
  • the cabin on the trolley is rotatably mounted about the vertical axis on a crane bridge that can be moved on crane tracks and that the work area is enclosed by a blasting house.
  • the framework conditions i.e. A lot can be saved on the blasting house, since the operator has optimal conditions in the work cabin.
  • Suction can be reduced to a minimum, for example, since even a very dusty atmosphere does not affect the operator in his cabin or the work process. Since the man is sitting in a heated room, there is no need for an air heating system. The lighting can be reduced to a relatively modest basic lighting. In this way, a great deal of energy can be saved and a blasting house can be used as a tent-like structure without fixed walls and ceiling, for example Construction to be set up outdoors.
  • reference numeral 1 denotes a work cabin with a seat for an operator.
  • the work cabin 1 is provided with a lockable entry opening and is supplied with conditioned fresh air via lines, not shown.
  • a viewing window 2 is inserted in the front of the cabin wall, through which the operator can observe the surroundings in front of the cabin.
  • Headlights 3 are attached to the outside of the cabin head or on the side walls and illuminate the working area in front of the cabin.
  • the Ka - binenfrontwand is surmounted by a kegelstumpfkcnischen bulge into which used a universal joint 27 (eg, cardan or ball joint) and in which a discharge nozzle 4 is held. The operator swings the jet nozzle 4 with a lever 5 attached to it.
  • a blasting house 28 encloses the working area and is usually provided with a grating floor 6 under which a beam medium return system is arranged.
  • the work cabin 1 is suspended from a suspension and rotating device 7, to which a vertically downwardly extending guide rod 8 is fastened. On this, the work cabin is guided in a longitudinally displaceable manner with rollers 9 mounted on its rear wall and can be moved up and down by means of a pull strap or cable 10.
  • the tension belt 10 runs over a deflection roller 11 onto a winch 12 which is driven by a motor 13.
  • the suspension and rotating device 7 is rotatable about an axis 14 and is supported at a distance from it via a roller 15 on a rotating ring 16.
  • the rotary drive has a toothed wheel 17, which meshes with the peripheral toothing of the turntable 17 which is concentric with the axis 14 and in turn can be driven by a motor 18 via a power transmission 19.
  • the slewing ring 16 is fastened by a connecting bracket 20 and with the axle 14 to a transverse drive 21 (trolley).
  • the transverse chassis 21 in turn runs with rollers that can be driven by a motor 30 on the supports 22 of the longitudinal chassis designed as a crane bridge. This is supported on rails 23 at the ends.
  • care must be taken to ensure that blasting agent cannot remain on the rail running surfaces.
  • the upwardly converging treads are inclined to the horizontal.
  • a motor 29 serves to drive the longitudinal undercarriage 22 and acts on the rollers 24 by means of a shaft indicated by dash-dotted lines.
  • the guidance of the blasting hose is not visible in the drawing. This is guided inside the work cabin 1 along the side wall to the rear and through the rear wall to the outside. It is pulled on the floor 6 by the movement of the working cabin 1.
  • the electrical feed and control lines are also not visible. These, too, are guided in loops in a known manner and are pulled up by the moving work cabin.
  • the embodiment described has the advantage that the various movements carried out by the drives 13, 18, 29 and 30 can be recorded by electronic sensors and the data can be stored. This enables repetitive work processes to be reproduced automatically and without occupying the work cabin.
  • the work cabin 1 can be mounted on a carriage which can be moved on the floor 6 or on a pivotable boom.
  • a blasting wheel can also be provided as the blasting unit, to which the blasting medium is fed by means of a hose.
