Definitions

  • the invention relates to a device for moving trusses for the Transport of workpieces to be galvanized on mounting rails using a Multiple chassis existing driving unit, the crossbar with each Chassis each with a lifting device for lowering the galvanized Workpieces in the zinc bath is connected.
  • the traversing devices known from practice exist from at least two parallel mounting rails, on which the Crossbeams along the processing stations of a galvanizing plant be transported.
  • the traversing devices known from practice exist from at least two parallel mounting rails, on which the Crossbeams along the processing stations of a galvanizing plant be transported.
  • the object of the invention is to avoid the floating of the workpieces to be galvanized in the zinc bath in a device for moving traverses for the transport of workpieces to be galvanized on mounting rails.
  • the solution to this problem by the invention is characterized in that the workpieces are suspended via rigid suspension devices on the underside of the cross member and that at least two lowering devices loading the ends of the cross member are arranged in the region of the galvanizing bath.
  • the lowering devices acting on the ends of the traverse cause the workpieces to be lowered below the bath surface the buoyancy caused by air in the workpieces, for example Heat exchanger tubes and tube bundles is generated.
  • the Lowering devices will press the workpieces under the Zinc bath surface causes the workpieces to be rigid Suspension devices are attached to the underside of the crossbar.
  • each lowering device is provided with a vibrating device, around the crossbar and those suspended from the underside of the crossbar Workpieces at least during the lowering of the workpieces in the Zinc bath as well as during the extraction of the workpieces from the zinc bath to undergo a shaking motion.
  • a vibrating device When immersing the workpieces in the Zinc bath makes the shaking movement easier for the liquid zinc to enter narrow gaps and voids; when pulling the workpieces out of the Zinc bath causes the vibrating device to shake off excess Zinc.
  • each Lowering device from at least one with a pivoting device connected, pivoted on a vertical post Lever arm, at its free end a pressure element for the one to be lowered Traverse is arranged.
  • a particularly good transmission of the shaking movement to the crossbeam and thus on the workpieces to be galvanized is achieved in that the advantageously designed as a rotary drive provided with an unbalance Vibration device on the arranged at the front end of the lever arm Pressure element is arranged.
  • FIG. 1 An embodiment of a traversing device according to the invention Lowering device for the traverse to be moved is shown below the accompanying drawing described in which a perspective view a traversing device according to the invention is shown schematically.
  • the traversing device shown in perspective is in essentially from a mounting rail 1, on which by means of one of several Undercarriages 2 existing driving unit trusses 3 for transporting along workpiece holders 4 hanging workpieces to be galvanized transported to the individual processing stations of a galvanizing plant can be.
  • chassis 2 arranged one behind the other have a chassis frame 5 on the top of which rollers 6 are mounted, by means of which the undercarriage 2 can be moved along the mounting rail 1.
  • a lifting device 7 for lowering the galvanizing workpieces in a - not shown - arranged zinc bath.
  • the lifting device 7 shown consists of a roller 8 on which a chain 9 can be wound up.
  • To transport the traverse 3 are on the top of the Traverse 3 support eyelets 10 are arranged, via which the traverse 3 with the chain 9 the lifting device 7 is connected.
  • a fastening profile 11 is arranged, to which the galvanizing workpieces at any distance from each other Suspension devices 12 and the workpiece holders 4 can be fixed.
  • Hanging devices 12 are rigid so that they can be attached to them attached workpieces when lowering the traverse 3 in the direction of Press the galvanizing bath under the surface of the zinc bath.
  • the lifting device 7 Since the traverse 3 with the workpieces attached to it via the chain 9 the lifting device 7 is connected, it can when lowering galvanizing hollow bodies, such as heat exchanger tubes and Pipe bundles, in the zinc bath, come in that due to the in the Workpieces contain air and due to the high viscosity of the Zinkbades the workpieces to be galvanized despite the rigid Float suspension devices 12, because of the lifting device 7 no pressure force can be exerted on the cross member 3.
  • hollow bodies such as heat exchanger tubes and Pipe bundles
  • the illustrated embodiment of the lowering devices 13 each consists of one connected to a pivoting device 14, on one vertical post 15 pivotally articulated lever arm 16, at the free end a pressure element 17 is arranged, which in the Actuation of the lowering device 13 grips the crossbar 3 and in the direction of the zinc bath.
  • Swiveling device 14 from a cylinder-piston unit, which for example, can be driven hydraulically or pneumatically.
  • each lowering device 13 is included a vibrating device 18 arranged at the front end of the lever arm 16 provided, for example as an unbalanced rotary drive is trained.
  • This is the truss 3 and the one on the underside of the truss 3 suspended workpieces with a shaking motion
  • Vibrating device 18 is used when inserting the workpieces into the zinc bath to the one hand air pockets and flux residues from the galvanized To remove workpieces and on the other hand uniform galvanizing of the To ensure workpieces.
  • the zinc solidifies when Immerse the workpieces briefly into one surrounding the workpieces Zinc block.
  • the lowering device 13 described above and the one with the Lowering device 13 connected vibrating device 18 work in operation the galvanizing plant as follows:
  • the workpieces to be galvanized are on trusses 3 by means of the trolleys 2 along a mounting rail 1 from processing station to processing station the galvanizing system.
  • the trusses 3 are over the Lowered lifting devices 7 in the direction of the zinc bath until the Immerse workpieces in the zinc bath.
  • To float the to galvanizing workpieces due to air pockets in or between to avoid the workpieces are in the area of the galvanizing bath at least two lowering devices loading the ends of the crossbar 3 13 arranged. These are provided with pressure elements 17 Lowering devices 13 press on the crossbar 3 from above and act in this way counteract buoyancy of the workpieces.
  • the floating of the workpieces is additionally prevented by the suspension devices 12 for Setting the workpieces on the cross member 3 are rigid, so that it due to the buoyancy of any relative movement between the Workpieces and the traverse 3 can come.
  • Lowering devices 13 each provided with a vibrating device 18 which the crossbar 3 and those suspended from the underside of the crossbar 3 Workpieces are subjected to a shaking movement.
  • This shaking motion the cross member 3 and the workpieces by the vibrating device 18 advantageously retained until the workpieces via the lifting device 7 have been pulled back out of the zinc bath to pass through the Shake off excess zinc from workpieces.
