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.
  • Manually operated ladle slide gate closures are used particularly in iron foundries, where it is difficult to supply actuation energy in the form of pressure medium pressure to the gate closure due to the limited space in the foundry.
  • manually operated G confusepfannenschieberver nowadaysn the thrust and Switzerlandkurbel is with the aid of the actuating rod is rotated by an angle of 0 9o for the closing or opening movement of the slide plate.
  • a difficulty with such manually operated ladle slide closures is that the mutually movable parts in both end positions, ie 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.
  • the invention proposes the basis of a manual actuating mechanism of the type mentioned above provides that the thrust and Glaskurbel is rotatable by at least 18 o 0, whereby the displacement of the slide plate and the rotation angle of the crank are so matched to one another such that the full opening 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.
  • the angular offset between the two insertion openings is appropriately 7o to 11o ⁇ . In this angular range, the ergonomically most favorable method of actuation results both for pivoting and for repositioning the actuating pin.
  • 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 slide closure After the first actuation path, the smaller passage opening at the top of the slide plate is closed and the larger passage opening at the bottom of the slide plate is still open.
  • the last-described embodiment of the invention has the particular advantage that incorrect operations are practically excluded due to the design features.
  • the slide plate of the three-plate slide closure 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 the push and pull crank 10.
  • the thrust and Buchkurbel lo is mounted to rotate on a rigidly connected to the ladle 2 bolts 11 to 18o 0th
  • the push and pull rod 9 engages the push and pull crank 1o at a distance from the axis of rotation thereof.
  • crank mechanism 9 formed by the push and pull crank 10 and the push and pull rod 9, 10 is located 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.
  • 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.
