Definitions

  • the invention relates to a support and guide frame for a continuous caster with interchangeable support segments supported on a support frame, in which the rollers of the opposing inner and outer guideway are mounted at a distance from each other, a in the center of the arc, along which the support segments are arranged Swivel lever, the length of which is shorter than the radial distance from the center to the support segments, with devices for detecting and pulling out individual support segments.
  • Changing devices for support segments of strand guides with a pivot lever are already known and described for example in DE-PS 1 285 095.
  • a carriage is movably arranged in the swivel lever, which engages under the guide segment and which, after it has been extended into the strand guide track, is connected to the segment to be extended and takes the segment with it.
  • the invention has for its object to provide an improved, structurally less complex changing device without the need for a separate carriage to accommodate a support segment, and in the safe is that the detected segment is securely held and guided during the expansion, the device can also be used for segments of heavy construction.
  • telescopic guide rails which can be telescoped in and out are provided which, after being pushed out into the strand guide track, comprise a support segment in the form of a fork, with counter guides attached to the support segment engaging with the guide rails reach, whereupon the support segment along the guide rails can be removed from the installation position.
  • the counter guides on the support segment are advantageously designed as wheels or rollers.
  • the pivot lever and the guide rails are expediently designed as C-shaped profiles and, in the retracted position, recesses are provided in the pivot lever and in the guide rails for passage of the counter-guides.
  • a cable winch for pulling out the segment and an actuating drive for pushing the guide rails in and out are arranged in the center of the circular arc.
  • a hydraulic drive which is movable with the swivel lever is preferably provided for pushing the guide rails in and out.
  • Another object of the invention is to be able to replace the support segments without jamming, etc. even if the center distances of adjacent rollers are very small.
  • At least one edge-side roller of the outer web attached to a support is releasably attached to the segment on each support segment, the carrier with the roller being removable into a recess on the support frame during the removal of the segment.
  • rollers This makes it possible to arrange the rollers at a very small distance from one another without colliding with an adjacent element when a segment is being removed.
  • FIGS. 1 to 4 each show a side view (partially sectioned) of a guide arch according to one embodiment.
  • FIG. 5 shows a view in the direction of arrow V of FIG. 1.
  • FIG. 6 shows a representation analogous to FIG. 1.
  • a one-piece circular-arched support frame 1 which is mounted on the foundation 2 by means of a fixed bearing 3 and two floating bearings 4, support surfaces 5 are provided which are machined inwards and on each of which a segment 6 is supported.
  • the support frame 1 could also be constructed in several parts, each of the parts being supported against the foundation by means of a fixed bearing and a floating bearing.
  • the segments 6 have machined mating surfaces 7 which match the supporting surfaces, so that the installation of the individual segments 6 is easily possible without fitting work in the event of an exchange.
  • the rollers 11 of the inner web 12 and the rollers 13-of the outer web 14 are mounted opposite one another at a distance from one another, with the edge-side first roller, which is designated by 16, in each case Outer web 14 is releasably attached to segment 6, etc. such that their bearings are arranged on a cross member 17, which in turn is releasably attached to segment 6.
  • a pivot lever 19 In the center 18 of the arcuate guideways 12, 14 is a pivot lever 19, the length 20 of which is shorter than the radial distance 21 from the center to the support segments 6, pivotally mounted.
  • a fixed cable drive 22 is used for pivoting, the cable 23 of which is attached to the end 24 of the pivot lever 19.
  • the pivoting lever 19 has two C-shaped profiles 25 arranged at a distance 26 from one another, the distance 26 being kept somewhat larger than the width 27 of the support segments 6.
  • these C-shaped profiles 25 there are also C-shaped profiles 28 - And extendable guide rails provided.
  • a pushable pinion 29, which is rotatably mounted in the center 18 and which engages in a toothed rack arranged on the underside of this C-shaped carrier, is used for pushing out and pushing in these guide rails.
  • a pressure medium cylinder 30 could also be provided, as shown in FIG. 6.
  • a cable winch 31 is also rotatably mounted, the cable 32 of which can be fastened to the segment 6 to be removed.
