Definitions

  • the invention relates to a zinc bath enclosure according to the preamble of patent claim 1.
  • Zinc baths for hot-dip galvanizing large workpieces can be 2 to 20 m long, 1 to 3 m wide and 1 to 3 m deep. They are arranged in a workshop either in the longitudinal direction or transversely to it. If a zinc bath is set up in the longitudinal direction of the workshop, it is usually no problem to immerse the workpiece in the zinc bath with the help of a traveling crane and then remove it again, even if the bath is surrounded by a housing, which serves to extract the vapors generated during the treatment in the zinc bath. For this purpose, it is only necessary to provide a longitudinal slot in the ceiling of the zinc bath enclosure, through which the wire cables of the overhead crane can be guided into the zinc bath enclosure from the outside inwards.
  • the slot is expediently provided with sealing means such as bristle strips or rubber lips so that as little vapors as possible escape to the outside.
  • Doors are provided in the end faces of the known zinc bath housing for introducing or removing the workpiece be opened. Since they open in the direction of transport of the overhead crane, they do not hinder the insertion of the workpieces.
  • a second major disadvantage is that these systems generally require long driveways with barges and thus there are idle times in the galvanizing bath. This is why cross-linked systems that are loaded with trolley tracks have prevailed in the galvanizing industry.
  • the above-mentioned housing system is not possible for baths arranged transversely to the hall direction.
  • housings are usually driven along with the galvanizing crane bridge.
  • the greatest advantage of transverse systems namely the time-saving loading of the zinc bath using trolley tracks arranged lengthways to the hall direction, is not possible.
  • major problems have arisen so far, since the existing conveyor systems can no longer be used and work processes have to be changed disadvantageously with regard to the capacity of the systems.
  • a cable or chain hoist engages not only on the top but also on the bottom roller door segment, which means that when the roller doors are closed, the bottom roller door segment can be raised in order to have access to the zinc bath and the workpiece which may be hanging above it.
  • the door segment located directly above it can also be raised in order to have greater freedom for access to the workpiece hanging above the zinc bath.
  • FIG. 1 shows a zinc bath housing 1 to be set up transversely to the transport direction in a workshop with two holding frames 10 and 10 ', which are arranged at a distance from one another.
  • the holding structures 10 and 10 ' are designed as U-shaped channels, through the interior of which the gases formed above the zinc bath can be extracted. The U is upside down.
  • the holding structures 10 and 10 ' are connected to one another under the workshop floor 19 by channels 13 and 13', which are therefore only indicated by dashed lines.
  • side walls 12, 12' are arranged which close the clear passage of the holding frames 10 and 10 'and to which fastening and guide elements for the roller doors 4 and 4' are attached.
  • doors 14, 14 'of a type known per se are provided in the side walls 12, 12', which provide access to the interior of the zinc bath housing 1.
  • the roller doors 4, 4 'consist of individual door segments 6, 6', 6 '', 6 ''',6''' are formed and each have a double bristle seal 8 at their upper ends, which extend over the entire length of the upper door segments 6 and through which the wire cables of a crane hook can extend into the interior of the zinc bath housing 1.
  • the double bristle seals 8 of the two door segments 6 together form a flow channel, which is also suctioned off for better sealing.
  • the uppermost door segment 6 is pulled upwards by a cable pull 16, 16 ', which is guided forwards or backwards via a deflection roller 18. It is clear to the person skilled in the art how to arrange and redirect such a cable pull.
  • FIG. 2 shows the zinc bath housing 1, which is open on one side, with the front roller door 4 open, which is lowered via the cable pull 16 and chain hoist 17.
  • the individual door segments 6 are placed on the factory floor 19 from the inside out, the uppermost door segment 6 being the farthest away from the zinc bath 2. Since the same parts as in FIG. 1 are provided with the same reference numerals, the doors 14, 14 'in the side walls 12, 12' and other elements of the zinc bath housing can easily be seen.
  • a closed railing 22 is shown, which is arranged around the zinc bath 2 to protect the operating personnel and, together with the closed housing, forms the bath enclosure.
  • FIG. 2 also shows the state of the zinc bath housing 1 before the introduction of a workpiece. This is positioned in the longitudinal direction of the workshop and thus in the direction of arrow A with the roller shutter 4 open above the zinc bath 2 and lowered so far that the crane hook is located lower than the bristle seal 8 inside the zinc bath housing 1.
  • the front roller door 4 can be closed again by the cable 16 pulling up the uppermost door segment. This takes the next door segment 6 'with it, which in turn pulls the next door segment upwards, etc., until the front roller door 4 is closed as shown in FIG. 1.
  • the door segment 6 '' '' is raised with the separate chain hoist 17.
  • FIG 3 shows a section along the line BB in Figure 2 to illustrate how the individual door segments 6-6 '''' are pulled up.
  • 12 guide tracks 26, 26'-26 '''' are arranged on the side wall, which are shown in the right part of FIG.
  • Each of the guideways 26 ..., 26 '''' is provided for one gate segment 6, 6 '..., 6'''. Since the uppermost gate segment 6 is to be the furthest outside, its guideway 26 is the longest and extends from the vicinity of the workshop floor 19 to the very top near the upper end of the side wall 12.
  • the inner guideway 26 'for the second gate segment 6 ' is already significantly shorter and ends approximately before the horizontal deflection of the outermost guideway 26.
  • the guideway 26''following inwards is even shorter, since the gate segment 6''guided in it is no longer pulled up completely, but instead hangs at the lower end of the second gate segment 6 '.
  • the guideways 26'-26 '''' are therefore becoming shorter and shorter, ie they extend less and less upwards from the shop floor 19.
  • each one hooks the following gate segment into the lower end of a previous gate segment and is pulled upwards by the cable 16.
  • pins arranged on the side edges can be used, which are gripped by shock-absorbed hooks of the next door segment.
  • any other driver connection can also be suitable for this, for example shoulders, which run along the lower edge of each door segment and which are gripped by the lugs of the respectively following door segment.
  • Figure 3 also shows the raising or lowering of the bottom gate segment 6 '' '' by a chain hoist 17 which engages the bottom gate segment 6 '' ''. This serves to have access to the zinc bath 2 when the zinc bath housing 1 is still closed, in order to position or treat the workpiece.
  • FIG. 3 also shows two suction openings 24 provided in the side wall 12, which lead into the interior of the holding frames 10 and, when the zinc bath housing 1 is closed, suck off the gases formed therein through the channels 13, 13 '. It is clear that, for this purpose, extraction fans should be arranged in the channels 13 and 13 ', respectively, which extract the gases.
  • FIG. 4 shows a section of the zinc bath housing according to FIG. 2, namely - seen in the direction of arrow A - from the left holding frame 10 'with the left side wall 12'.
  • the side wall 12 ' is carried by a stand 28.
  • the door segments 6 are lowered and it can be seen how the chain hoist 17 acts on the lowest door segment 6 '''' in order to pull it upwards according to the left part of FIG. 3.
  • the chain hoist 17 is guided upwards and outwards via deflection rollers 18. At the ends of the chain hoist 17 engage chain wheels which are driven by a motor, not shown.
  • FIG. 4 also shows a schematic view of the guideway 26, which leads the uppermost gate segment 6 to the very top. It is pointed out that the second holding frame 10 'is constructed symmetrically and that guideways 26 and cable pulls 16 and chain hoists 17 are arranged on each holding frame 10 or 10'.
