Definitions

  • FIG. 4 One of the possibilities made possible by the overall arrangement consisting of the adjustable passenger platform 38 and the lifting mast described is shown in FIG. 4.
  • the bridge plate 50 of an elevated road 52 which, as shown at 53, is elevated.
  • the lifting mast can be adjusted from its folded - roll-folded - position, as described above, in such a way that its basic boom 15, its boom center piece 21 and its flyer 26 move in the direction of the stand 53 of the bridge plate 50 Form open U, the platform 38 being held horizontally in a manner to be described during the entire pivoting movement. The same goes for the back folding the mast into the rolled-up position.
  • Each voltage change is applied to the electronic threshold circuit 94a, 94b via an integrator 93 and compared with adjustable setpoints. In the circuit shown, these can be ⁇ 2 °, 0 ° ⁇ 8 °.

Claims (6)

1. Plate-forme detravail (38) d'horizontalité réglable, comportant un bras-support (42) associé à une articulation (43) permettant de faire pivoter la plate-forme dans le plan des tronçons articulés (15, 21, 26) d'une volée en plusieurs parties d'un appareil de levage portant la plate-forme (38) ; celle-ci étant prévue pour être maintenue automatiquement en position horizontale par un moteur réversible (97) tel qu'un moteur électrique, qui commande la plate-forme par l'intermédiaire d'un mécanisme de réduction (66, 67), et qui est asservi à un régulateur pourvu d'un inclinomètre (92); le mécanisme de réduction étant constitué par des trains d'engrenages (66, 67), et attaquant directement la partie tournante (64) de l'articulation (43) du bras-support de la plate-forme (38); celle-ci étant caractérisée en ce que son système de réglage comporte plusieurs accouplements à sens unique (81, 86), disposés entre le bras-support (42) et le moteur (97), qui empêchent un pivotement indésirable du bras-support (42) de la plate-forme dans un sens ou dans l'autre, et qui permettent chacun le pivotement du bras-support (42) dans le sens voulu, correspondant à l'un des sens de rotation du moteur (97) d'horizontalité de la plate-forme.
2. Plate-forme de travail conforme à la revendication 1, caractérisée en ce que le mécanisme (66, 67) est fixé à la flèche de la volée de l'appareil de levage par une bride boulonnée qui fait partie du carter (75) de ce mécanisme; celui-ci comportant un étage d'entrée à vis sans fin (66) entraînée par le moteur (97), qui fait tourner un mécanisme épicycloïdal de sortie (67), par l'intermédiaire des accouplements à sens unique (81, 86) incorporés dans le mécanisme d'entrée; et en ce qu'un arbre de commande à main (83), actionné au moyen d'un volant à manivelle (84, 85), est prévu pour attaquer les accouplements à sens unique (81, 86) en court-circuitant le mécanisme d'entrée à vis sans fin (66).
3. Plate-forme de travail conforme à l'une des revendications 1 ou 2, caractérisée en ce que le moteur électrique (97) est un moteur à rotor plat ou à rotor creux, et en ce que le mécanisme de réduction (67) est constitué par des trains d'engrenages planétaires (I, l', I") disposés en série.
4. Plate-forme de travail conforme à l'une des revendications 1 à 3, caractérisée en ce que le moteur (97) qui assure l'horizontalité de la plate-forme (38) est alimenté par une batterie (91 ) pourvue d'un régulateur de charge.
5. Plate-forme de travail conforme à l'une des revendications 1 à 4, caractérisée en ce que la volée de l'appareil de levage prévue pour porter la plate-forme est constituée par la volée d'un appareil connu en lui-même pour distribuer le béton à couler sur un chantier; cette volée articulée en plusieurs parties comportant un tronçon de base (15), un tronçon intermédiaire (21 ), et une flèche (26), qui peuvent être manoeuvrés en inclinaison relative l'un par rapport à l'autre, au moyen de vérins (17, 23) associés aux articulations de la volée, et permettant un débattement de 180° à l'endroit de chaque articulation; l'ensemble de cette volée articulée étant conçu pour permettre de replier la volée en rabattant la flèche (26) entre le tronçon intermédiaire (21 ) et le tronçon de base (15) de la volée; et la pointe (28) de la flèche (26) étant pourvue d'un organe d'accouplement démontable (29), adapté à recevoir au choix un embout de distribution (35) pour le béton, ou une pièce de liaison (31 ) qui porte l'articulation (43) du bras-support (42) de la plate-forme de travail (38).
6. Plate-forme de travail conforme à l'une des revendications 1 à 5, caractérisée en ce que la pièce de liaison (31 ) qui porte l'articulation (43) est en matériau isolant, et en ce que le système de commande d'horizontalité de la plate-forme (38) est agencé pour être actionné par une liaison radio, ou par l'intermédiaire d'un câble à fibres optiques.
