Definitions

  • This invention relates to a transfer arrangement and, in particular but not exclusively, to an arrangement for linear transfer of heavy or bulky items.
  • the carriage may include wheels or rollers for engaging the track.
  • the wheels or rollers may be configured such that the carriage will be moveable even if one wheel or roller should collapse.
  • the carriage may include three pairs of wheels for engaging a pair of rails, and if one wheel collapses the carriage remains supported and moveable on the rails.

Claims (9)

  1. Dispositif de transfert installé dans un plancher, comprenant :
    un support (32) pour un élément à transférer ;
    un cylindre sans tige (26) comprenant un piston monté sous le niveau du plancher (12) ;
    le cylindre (26) définissant une première fente qui est normalement fermée par un joint, le joint étant disposé pour permettre à un élément (27) raccordé avec le piston de se déplacer le long de la première fente avec le piston ;
    un moyen (30) s'étendant à travers une seconde fente (28) dans le plancher et raccordant le support (32) avec ledit élément (27) ;
    un moyen (54, 58, 59) pour fournir un fluide pressurisé au cylindre (26) pour déplacer le piston à travers le cylindre et donc le support (32) le long de la seconde fente (28) dans le plancher,
       caractérisé en ce que :
    ledit moyen pour raccorder le support (32) audit élément (27) comprend un chariot (24) mobile le long d'une piste (22, 23) sous la forme d'une paire de rails s'étendant des deux cotés du cylindre sans tige (26), le support (32) étant situé au-dessus du niveau de plancher (12) et le chariot et la piste se trouvant sous le niveau du plancher.
  2. Dispositif de transfert pour l'installation dans un plancher, comprenant :
    un cylindre sans tige (26) définissant une première fente ;
    un boítier (14) pour l'installation dans le plancher et ayant la seconde fente (28) dans une paroi supérieure de celui-ci ;
    un support (32) pour un élément à transférer, le support étant situé à l'extérieur du boítier dans une relation superposée au-dessus de ladite paroi supérieure du boítier ;
    le cylindre sans tige (26) comprenant un piston, le cylindre étant situé sous le support et dans le boítier (14), la première tige étant normalement fermée par un joint et la tige étant disposée pour permettre à l'élément (27) raccordé au piston de se déplacer le long de la première fente avec le piston ;
    le moyen (30) s'étendant vers le haut à travers la seconde fente (28) dans la paroi supérieure du boítier et raccordant le support (32) audit élément (27) ; et
    le moyen (54, 58, 59) pour fournir un fluide pressurisé au cylindre (26) pour déplacer le piston à travers le cylindre et donc le support (32) le long de la seconde fente (28) dans la paroi supérieure,
       caractérisé en ce que ledit moyen (30) pour raccorder le support (32) avec ledit élément (27) comprend un chariot se déplaçant sur une piste située dans le boítier (14) ledit chariot et ladite piste se trouvant sous la paroi supérieure du boítier (14) et du support (32).
  3. Dispositif de transfert selon la revendication 1 ou 2 dans lequel le cylindre sans tige (26) est un cylindre d'air pneumatique.
  4. Dispositif de transfert selon l'une quelconque des revendications précédentes dans lequel le fluide pressurisé est fourni aux deux extrémités du cylindre, permettant au piston de se déplacer dans les deux directions sous la commande de fermeture, le déplacement du piston étant réalisé par un échappement commandé du fluide à partir d'une extrémité du cylindre.
  5. Dispositif de transfert selon l'une quelconque des revendications précédentes dans lequel la piste est sous la forme d'une paire de rails parallèles (58, 59) avec le cylindre (26) situé entre eux.
  6. Dispositif de transfert selon l'une quelconque des revendications précédentes dans lequel le chariot comporte des roues ou des rouleaux (38) pour être en prise avec la piste.
  7. Dispositif de transfert selon la revendication 1 ou l'une quelconque des revendications 3 à 6 lorsqu'elles dépendent de la revendication 1 dont les parties du dispositif placé sous le niveau de plancher (12) sont montées dans le boítier (14) incorporé dans le plancher et définissant la seconde fente (28) dans le plancher.
  8. Dispositif de transfert selon l'une quelconque des revendications précédentes dans lequel un raccordement (46, 48) entre le support (32) et le piston permet un degré de déplacement perdu dans la direction verticale, de sorte que, dans l'utilisation, des charges portées par le support ne sont pas transmises dans la direction verticale au piston.
  9. Dispositif de transfert selon l'une quelconque des revendications précédentes dans lequel le raccordement (46, 48) entre le piston et le support (32) est libérable pour que, lorsque le raccordement est libéré, le support soit mobile indépendamment du piston.
