Definitions

  • the invention relates to a method and a device for fastening the cross bars.
  • One application for such a device is the conveyance of hot cement clinker over the grate, the clinker being treated, in particular cooled, by a gas flowing through the grate and the material bed from below.
  • WO 98/48231 Devices for the treatment of bulk material by means of a gas, in particular bulk material cooler, are known (WO 98/48231) in which a bed of the bulk material lying on a stationary grate is arranged through a series of transversely to the conveying direction and in front of and in the conveying direction moving back rods is promoted.
  • the crossbars are attached to longitudinal bars of a frame, which are set into an oscillating movement by a hydraulic or eccentric drive parallel to the conveying direction.
  • the cross bars are usually wedge-shaped in cross-section and arranged so that the blunt side points in the conveying direction. The blunt side offers more resistance to the cement clinker than the pointed side.
  • This object is achieved in that a positive and / or non-positive connection is created by moving the crossbars relative to a support part or the / support parts, which connection is secured against displacement.
  • An undercut seat is provided on the carrier part and an insertion area and a seating area are provided on the crossbar, of which the insertion area has a width that fits through the constriction of the seat and the seating area has a cross-sectional shape that interacts positively or non-positively with the seat.
  • FIG. 1 shows a perspective view of a first arrangement of transverse and longitudinal bars
  • FIG. 2 shows a cross section through a transverse bar
  • Longitudinal bars 3 are provided as the carrier part for cross bars 1.
  • seats 5 for cross bars 1 are formed by pairs of mutually opposite, undercut projections.
  • the seats 5 between the projections 4 have a clear cross section, the

  • the main load direction is in and against the conveying direction, as well as up and down.
  • the crossbars can be easily inserted into the seats, they are provided with recesses 2, in the area of which the crossbars have a smaller width than the constriction between the lugs of the projections 4 which project towards one another.

  • the areas in which the recesses 2 suitable for insertion into the seats are located are referred to in the claims as insertion areas.
  • the areas of the longitudinal bars that are ultimately to be held in a form-fitting manner in the seats are referred to as seating areas.
  • the cross bars 1 are inserted with their insertion areas into the seats from above. Subsequently they are moved in their longitudinal direction so that the seating areas get into the seats 5.
  • the cross-sectional contour of the seat areas of the crossbar 1 and the seats 5 may be conical or wedge-shaped, the wedge axis roughly matching the longitudinal direction of the crossbar. After being inserted into a seat, it is slid in its longitudinal direction until the wedge shape engages. The wedge angle and the assembly force are chosen so that self-locking occurs. The crossbar is then held non-positively in the seat. In such a case, the previously described positive locking may be dispensed with.
  • Fig. 2 shows a cross bar 10, which in the upstroke arrow 11 forms a cavity below its top plate and behind its end plate, into which it can easily move in the return stroke, so that it finds less resistance corresponding to a lower conveying effect in the return stroke than in the preliminary stroke.

Abstract

L'invention concerne un procédé et un dispositif pour fixer des barres transversales (1) dans un refroidisseur à grille à barres transversales. En déplaçant ou en faisant tourner une barre transversale (1) par rapport à une pièce de support (3), on réalise un assemblage par liaison de forme, liaison de force ou par liaison de forme et de force entre la pièce de support (3) et la barre transversale (1). Sur la pièce de support (3) est ménagé un siège (5) contre-dépouillé et la barre transversale (1) est pourvue d'une zone d'insertion et d'une zone d'appui. La zone d'insertion présente une largeur adaptée à la cavité du siège, et la zone d'appui présente une forme de section coopérant avec le siège (5) par liaison de forme ou de force. On fait passer la barre transversale (1), par déplacement longitudinal et/ou rotation, de la position dans laquelle la zone d'insertion repose dans le siège (5) à la position dans laquelle sa zone d'appui repose dans le siège (5), et inversement.
