Abstract

The automatic device for opening and closing a hopper 2 hatch 1 of a railway wagon is characterised according to the invention in that it comprises a rotary control shaft 3, parallel to the longitudinal axis of the wagon, connected by means of a plurality of lever mechanisms 4, 5 articulated to the said hatch and by means of a manoeuvring connecting rod 6 to the rod of a pneumatic thrust cylinder 8 fixed to the wagon, the said shaft being mounted so as to rotate between a position for which the hatch is open and a position for which the hatch is closed, by means of the said thrust cylinder, under the action of control means, the said thrust cylinder being connected, through the control means, to a reservoir 9 of compressed air itself connected, through a non-return valve 10 with a threshold, to the main braking air line of the wagon.

Description

La présente invention a pour objet un dispositif d'ouverture et de fermeture dune trappe de trémie d'un wagon de chemin de fer. The present invention relates to a device for opening and closing a hopper hatch of a railway wagon.

Actuellement les dispositifs d'ouverture et de fermeture des trappes de trémies de wagons de chemin de fer sont commandés par des mécanismes hydrauliques. Selon l'invention on propose un système d'ouverture et de fermeture des trappes de trémies au moyen d'un circuit d'air comprimé ce qui a pour avantage, outre la plus grande rapidité des manoeuvres, de pouvoir utiliser la conduite d'air de freinage du wagon. Currently the devices for opening and closing the hopper hatches of railway cars are controlled by hydraulic mechanisms. According to the invention there is provided a system for opening and closing the hopper doors by means of a compressed air circuit, which has the advantage, in addition to the greater speed of maneuvers, of being able to use the air line. braking system.

Le système selon 1 invention convient aussi bien pour les trappes sur wagons à déchargement unilatéral ou bilatéral.The system according to the invention is equally suitable for hatches on unilateral or bilateral unloading wagons.

L'invention concerne donc un dispositif automatique d ouverture et de fermeture d'une trappe de trémie d un wagon de chemin de fer, caractérisé en ce qu'il comprend un arbre rotatif de commande, parallèle à'axe longitudinal du wagon, relié par 1 intermédiaire de plusieurs mécanismes à leviers articulés à ladite trappe et par l'intermédiaire d'une biellette de manoeuvre à la tige d'un vérin pneumatique fixé sur le wagon, ledit arbre étant monté rotatif entre une position d'ouverture de la trappe et une position de fermeture de celle-ci, par ledit vérin, sous l'action de moyens de commande, ledit vérin étant relié, à travers les moyens de commande, à un réservoir d'air sous pression lui-meme relié. à travers une vanne anti-retour à seuil, à la conduite principale d'air de freinage du wagon. The invention therefore relates to an automatic device for opening and closing a hopper hatch of a railway wagon, characterized in that it comprises a rotary control shaft, parallel to the longitudinal axis of the wagon, connected by 1 intermediary of several lever mechanisms articulated to said hatch and by means of an operating rod to the rod of a pneumatic jack fixed to the wagon, said shaft being rotatably mounted between an open position of the hatch and a closed position thereof, by said cylinder, under the action of control means, said cylinder being connected, through the control means, to a pressurized air tank itself connected. through a threshold check valve, to the main brake air line of the wagon.

Le mécanisme à leviers comprend notamment deux leviers articulés l'un par rapport à l'autre à l'une de leurs extrémités, l'autre extrémité de l'un des leviers étant fixée sur l'arbre de commande et l'autre extrémité de l'autre levier étant articulé sur la trappe. The lever mechanism notably comprises two levers articulated relative to each other at one of their ends, the other end of one of the levers being fixed on the control shaft and the other end of the other lever being articulated on the hatch.

La description suivante donnée en regard des dessins annexés est donnée à titre d'exemple de réalisation de l'invention. The following description given with reference to the appended drawings is given by way of example of embodiment of the invention.

Sur ces dessins
- la Fig. 1 est une vue au plan partiel du dispositif d'ouverture et de fermeture d'une trappe de trémie selon l'invention,
- la Fig. 2 est une section suivant 2-2 du dispositif de la Fig. 1, et
- la Fig. 3 est une vue en coupe Suivant 3-3 du dispositif de la Fig. 1.On these drawings
- Fig. 1 is a partial plan view of the device for opening and closing a hopper hatch according to the invention,
- Fig. 2 is a section along 2-2 of the device of FIG. 1, and
- Fig. 3 is a sectional view along 3-3 of the device of FIG. 1.

Le dispositif automatique d'ouverture et de fermeture d'une trappe 1 de trémie 2 d'un wagon de chemin de fer représenté sur les Figs. 1 et 2 comprend essentiellement un arbre rotatif de commande 3 suivant l'axe longitudinal du wagon, lequel arbre 3 est relié, par l'intermédiaire plusieurs mécanismes de leviers 4,5 articulés entre eux, à la trappe 1 (Fig. 3). L'arbre 3 est par ailleurs relié, par l'intermédiaire d'une biellette 6 de manoeuvre, à la tige 7 d'un vérin pneumatique 8 fixé sur le wagon (Fig. 2).On voit sur la Fig. 3 que le mécanisme à leviers comprend notamment deux leviers 4, 5 articulés l'un par rapport à l'autre à l'une de leurs extrémités, l'autre extrémité de l'un des leviers 5 étant fixée sur l'arbre de commande 3, et l'autre extrémité de l'autre levier 4 étant articulée sur la trappe 1. The automatic device for opening and closing a hopper hatch 2 of a railway wagon shown in FIGS. 1 and 2 essentially comprises a rotary control shaft 3 along the longitudinal axis of the wagon, which shaft 3 is connected, by means of several lever mechanisms 4.5 hinged together, to the hatch 1 (Fig. 3). The shaft 3 is also connected, by means of an operating rod 6, to the rod 7 of a pneumatic cylinder 8 fixed on the wagon (Fig. 2). We can see in Fig. 3 that the lever mechanism comprises in particular two levers 4, 5 articulated with respect to each other at one of their ends, the other end of one of the levers 5 being fixed on the control shaft 3, and the other end of the other lever 4 being articulated on the hatch 1.

L'arbre 3 est monté rotatif entre une position d'ouverture de la trappe et une position de fermeture de celle-ci réglées par le vérin pneumatique 8, sous l'action des moyens de commande. Le vérin 8 est relié, à travers les moyens de commande, à un réser voir 9 d'air sous pression qui est lui-meme relié. à travers une vanne 10 anti-retour à seuil, à la conduite principale d'air de freinage du wagon. Ainsi le dispositif selon l'invention utilise avantageusement le système de freinage par air comprimé déjà existant.  The shaft 3 is rotatably mounted between an open position of the hatch and a closed position thereof adjusted by the pneumatic cylinder 8, under the action of the control means. The jack 8 is connected, through the control means, to a reservoir 9 of pressurized air which is itself connected. through a threshold check valve 10, to the main brake air line of the wagon. Thus the device according to the invention advantageously uses the already existing compressed air braking system.
