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, is mounted with extendable and retractable devices for gripping and pulling out individual support segments.
  • the invention has for its object to provide an improved, structurally less complex changing device without the need for a separate car to accommodate a support segment, and in which it is ensured that the detected segment is securely held and guided during removal, 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 support 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-mounted roller of the outer guideway attached to a support is detachably attached to the support segment on each support segment, the support with the roller being removable into a recess on the support frame during the removal of the support segment.
  • fig. 1 through 4 each show a side view (partially sectioned) of a guide arch according to an embodiment.
  • Fig. 5 shows a view in the direction of arrow V of Fig. 1.
  • fig. another embodiment is shown in a representation analogous to FIG. 1.
  • support surfaces 5 are provided which are machined inwards and on which a support 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 support segments 6 have machined mating surfaces 7 which match the support surfaces 5, so that the installation of the individual support segments 6 is easily possible without fitting work in the event of an exchange.
  • the rollers 11 of the inner guideway 12 and the rollers 13 of the outer guideway 14 are mounted opposite one another at a distance from one another, with the edge-side first roller, which is denoted by 16, in each case the outer guideway 14 is releasably attached to the support segment 6, etc. such that their bearings are arranged on a cross member 17, which in turn is releasably attached to the support segment 6.
  • a stationary cable drive 22 is used for pivoting, the cable 23 of which is attached to the end 24 of the pivot lever 19.
  • the pivot lever 19 has two C-shaped profiles 25 arranged at a distance 26 from one another, the Distance 26 is kept somewhat larger than the width 27 of the support segments 6.
  • guide rails which can be inserted and pushed out are also provided as C-shaped profiles 28.
  • 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 attached to the support segment 6 to be removed.
  • the roller 16 mounted on the support 17 is detached from the support segment 6 by loosening the support 17 and the support is fastened together with the roller in the recess 10 provided on the support frame 1.
  • the guide rails 28 are displaced outwards, the guide rails 28 engaging with counter guides arranged on the sides of the support segments 6, which are designed as wheels 33.
  • the rope 32 is then attached to the support segment (FIG. 1).
  • the support segment 6 is pulled back by means of the cable 32 until it is in the expanded position shown in FIG. 2.
  • the retraction movement of the support segment 6 is limited by a stop 34.
  • the guide rails 28 are then withdrawn until they are in the retracted position shown in FIG.
