Definitions

  • the hoist main body 10 has a rope entrance opening around which there are provided a damper spring 11, a rope guide 12, damper rubber 13, rope stoppers 14, 15 etc.
  • the hanger 2 has a check plate 16 disposed to close the open mouth of the hook.
  • the check plate 16 is rotatable about a pin 17 and is normally biased by a spring 18 which intends to rotate the check plate 16 clockwise (as viewed in the drawing of Fig. 2).
  • the motor covers 41, 42 and the other casing member 21 support a rotary shaft 47 through ball bearings 43, 44 and 46.
  • the aforementioned air motor 50, the brake unit 60 and planet gear mechanism 80 are mounted on the rotary shaft 47 .
  • the air motor 50 is between the motor covers 41 and 42 and has rotor 51 and vanes 52. By the force of air supplied through the valve cylinders 27 and 28, the rotor 51 is rotated to rotate the rotary shaft 47.
  • the brake unit 60 operates in the following manner:

Claims (2)

1. Treuil pneumatique comprenant un moteur pneumatique réversible (50), un dispositif (25, 35) de commande pneumatique de la rotation du moteur, un tambour (70) qui peut être entraîné en rotation par le moteur afin qu'il assure l'enroulement et le déroulement d'un fil autour du tambour, un dispositif (91) à roue indicatrice de la rotation du tambour, pouvant être entraîné en rotation lorsque le tambour tourne de façon continue, et un dispositif (40) agissant sur le dispositif de commande afin qu'il arrête le fonctionnement du moteur après une rotation prédéterminée du dispositif à roue indicatrice, caractérisé en ce que:
le dispositif (91) à roue indicatrice est placé près d'une périphérie du tambour et est entraîné en rotation par intermittence lorsque le tambour tourne de façon continue, le tambour ayant un organe (94) qui y est fixé et qui a une position telle qu'il peut coopérer successivement avec une série de saillies (91a) portées par le dispositif à roue indicatrice afin qu'il assure la rotation par intermittence du dispositif à roue indicatrice, le dispositif à roue indicatrice ayant une saillie (91 b) qui constitute le dispositif agissant sur le dispositif de commande.
2. Treuil selon la revendication 1, comprenant:
une source pneumatique (113),
un premier conduit destiné à transmettre du fluide de la source au moteur (50) afin que le moteur soit entraîné en rotation dans un sens d'enroulement du fil,
un second conduit destiné à transmettre du fluide de la source au moteur afin qu'il fasse tourner le tambour dans un sens de déroulement du fil,
le dispositif de commande comprenant:
un dispositif (25) à obturateur, qui peut être commandé manuellement et qui est destiné à commander la circulation du fluide dans le premier conduit,
un second dispositif (30) à obturateur qui peut être commandé manuellement et destiné à commander la circulation du fluide dans le second conduit,
un troisième dispositif (35) à obturateur placé dans le second conduit en aval du second dispositif à obturateur,
un troisième conduit monté en dérivation à partir du second conduit entre le troisième dispositif à obturateur et le second dispositif à obturateur et relié au troisième dispositif à obturateur pendant le fonctionnement,
un quatrième dispositif (40) à obturateur placé dans le troisième conduit et associé pneu- matiquement au troisième dispositif à obturateur,
l'arrangement étant tel que, lorsque le dispositif à roue indicatrice est entraîne en rotation d'un angle prédéterminé dans des conditions dans lesquelles le second dispositif à obturateur est déplacé manuellement en position d'ouverture permettant la circulation du fluide, le quatrième dispositif à obturateur est mis en position d'ouverture par le dispositif à roue indicatrice afin qu'il permette l'écoulement du fluide dans le troisième conduit et provoque ainsi la mise du troisième dispositif à obturatuer en position de fermeture avec interruption de l'écoulement du fluide dans le second conduit et arrêt du fonctionnement du moteur dans le sens de déroulement du fil.
