Definitions

  • the invention relates to a manual actuation mechanism for a ladle slide closure, with a push and pull rod displacing the slide plate, which is articulated to a slide plate carrier and a push and pull crank which can be rotated by means of an actuating rod.
  • a difficulty with such manually operated ladle slide closures is that the mutually movable parts in both end positions, i. H. in the open position and in the closed position, stick together by adhering solidifying metal and can therefore only be set in motion with great effort.
  • the slide plate can be moved relatively easily.
  • attempts have been made in the prior art to extend the actuating rod so that a longer lever arm is available for turning the crank.
  • an excessively long actuating rod is difficult to handle and cannot be operated properly due to the limited space.
  • the invention proposes, starting from a manual actuation mechanism of the type mentioned at the outset, that the push and pull crank can be rotated by at least 180 °, the displacement path of the slide plate and the angle of rotation of the crank being matched to one another such that the full open position and the full closed position of the slide plate coincide with the two dead centers of the crank mechanism.
  • the invention cleverly uses the fact that with a crank mechanism in the dead center area the stroke goes to zero and the lifting force is theoretically infinitely large. In this way it is possible to provide a very large actuating force for the initial movement of the slide plate from the open or closed position without the actuating lever needing to be excessively long.
  • an expedient development of the invention provides that the actuating rod can be inserted into two angularly offset insertion openings assigned to the crank. In this way, it is possible to divide the angular path of the crank into two sections, although the actuating rod must be moved from the first insertion opening into the second insertion opening. For the movement of the slide plate from the intermediate position which it assumes when the actuating rod is repositioned, no particularly large actuating forces are required because, during the short repositioning time, parts which move against one another cannot solidify due to solidifying metal.
  • the angular offset between the two insertion openings is suitably 70 ° to 110 °. In this angular range, the ergonomically most favorable method of actuation results both for pivoting and for repositioning the actuating rod.
  • the invention provides that the passage opening of the slide closure, viewed in the direction of displacement, is made smaller on the upper side of the slide plate than on the underside thereof, and that the first insertion opening of the crank is fitted such that the slide plate is closed at the end of the first when the slide closure is closed
  • Actuating path shuts off the smaller passage opening on the top of the slide plate and leaves the larger passage opening on the underside of the slide plate still open.
  • the slide plate of the three-plate The slide lock can in no case be closed in one go, so that it is excluded with certainty that liquid metal remains in the passage opening of the slide plate.
  • the slide closure is designated in its entirety with the reference number 1. It is arranged in a known manner on the bottom of a ladle 2 and has a top plate 3, a slide plate 4, a support plate 5 and an outlet sleeve 6.
  • the slide plate 4 is fastened in a slide plate carrier 7, which is slidably mounted in the housing 8 of the slide closure 1.
  • a push and pull rod 9 is used, which is cranked in the length range and is articulated both on the slide plate carrier 7 and also on a push and pull crank 10.
  • the push and pull crank 10 is rotatably mounted on a bolt 11 which is firmly connected to the ladle 2 by 180.
  • the push and pull rod 9 engages on the push and pull crank 10 at a distance from its axis of rotation.
  • crank mechanism 9, 10 formed by the push and pull crank 10 and the push and pull rod 9 is both in the open position of the slide closure (see FIG. 1) and in the closed position of the slide closure (see FIG. 3) at the two dead centers, so that when the push and pull crank 10 is rotated, a very large actuating force is initially applied by means of the actuating rod 14 inserted into the insertion openings 12 and 13, respectively.
  • the passage opening 15 of the slide closure is smaller on the upper side of the slide plate 4 than on the underside thereof. Furthermore, the first insertion opening 13 of the crank is arranged so that the slide plate 4 closes the small passage opening at the top of the slide plate 4 when the slide closure is closed at the end of the first actuation path and leaves the larger passage opening on the underside of the slide plate 4 still open.
