Description

Dispositif pour ouvrir et fermer les toitures enroulables des wagons tombereaux à toit ouvrant.Device for opening and closing the roll-up roofs of sunroof wagons.

Les wagons tombereaux à toit ouvrant sont équipés, à l'une de leur extrémité, d'un mécanisme qui permet d'enrouler les éléments formant la toiture sur un tambour pour dégager entièrement la surface du plancher, puis de dérouler ces mêmes éléments pour refermer le toit. The sunroof wagons are equipped at one end with a mechanism that allows the elements forming the roof to be wound on a drum to completely clear the surface of the floor, then unroll the same elements to close the roof.

Le tambour est actionné par un groupe de deux manivelles accouplées placées à des hauteurs différentes, de chaque côté dru wagon, pour permettre leur manoeuvre tant à partir du sol, que d'un quai. The drum is operated by a group of two mated cranks placed at different heights on each side dru wagon, to allow their maneuver both from the ground, a quay.

Suivant le type de wagon, l'ouverture ou la fermeture de la toiture peut nécessiter de 80 à 160 tours de manivelle. Depending on the type of wagon, the opening or closing of the roof may require 80 to 160 turns of crank.

Ces opérations sont très pénibles pour le personnel, car les mécanismes sont souvent rouillés et parfois déformés. These operations are very painful for the staff because the mechanisms are often rusty and sometimes distorted.

L'invention a pour but de proposer un dispositif simple permettant d'actionner les manivelles de manière rapide et sure, sans efforts pénibles pour le personnel, et en faisant une économie de temps considérable. The invention aims to provide a simple device for operating the cranks quickly and securely, without strenuous efforts for staff, and saving a considerable time.

Ce but est atteint selon l'invention par un dispositif qui comprend
- un chassis mobile horizontalement et comportant une table réglable en hauteur par un dispositif de réglage manuel ou motorisé,
- un moyen d'entraînement rotatif dans les deux sens, à axe de rotation horizontal,
- un manchon comportant une première extrémité susceptible de venir en prise avec le moyen d'entraînement, et une seconde extrémité susceptible de venir s'adapter sur au moins une partie de l'axe et du bras de la manivelle. This object is achieved according to the invention by a device which comprises
- A horizontally movable frame and having a table adjustable in height by a manual or motorized adjustment device,
a rotary drive means in both directions, with a horizontal axis of rotation,
- A sleeve having a first end engageable with the drive means, and a second end adapted to fit on at least a portion of the axis and the arm of the crank.

Avantageusement, la table est réglable en hauteur par un système de parallélogramme articulé déformable. Advantageously, the table is adjustable in height by a deformable articulated parallelogram system.

Avantageusement, le dispositif de réglage manuel comprend un volant solidaire d'une tige filetée. Advantageously, the manual adjustment device comprises a flywheel secured to a threaded rod.

Avantageusement, le moyen d'entraînement rotatif est un outil du type perceuse, à air comprimé. Advantageously, the rotary drive means is a tool of the drill type, with compressed air.

Avantageusement, il est prévu un sabot de frein manoeuvrable par les pieds de l'opérateur. Advantageously, there is provided a brake shoe operable by the feet of the operator.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode préféré de réalisation. Il sera fait référence aux dessins annexés sur lesquels:
- la figure 1 est une vue en perspective du dispositif conforme à l'invention,
- la figure 2 est une vue de détail de l'extrémité du manchon s'adaptant sur la manivelle dtenrou- lement du toit ouvrant dfun-wagon. The invention will be better understood on reading the following description of a preferred embodiment. Reference will be made to the accompanying drawings in which:
FIG. 1 is a perspective view of the device according to the invention,
FIG. 2 is a detailed view of the end of the sleeve fitting on the handle crank of the sunroof of a wagon.

Le dispositif 1 comprend un chassis 2 mobile horizontalement grâce à quatre roulettes 3. Sur le chassis 2 est montée une table 4 réglable en hauteur grâce à deux systèmes de parallèlogrammes déformables articu- lés 5a et 5b. Des barres 6 relient deux couples d'articulations opposés des systèmes déformables 5a, 5b. The device 1 comprises a frame 2 movable horizontally by means of four rollers 3. On the frame 2 is mounted a table 4 adjustable in height thanks to two articulated deformable parallelogram systems 5a and 5b. Bars 6 connect two pairs of opposite hinges of the deformable systems 5a, 5b.

Une tige 7 filetée à double sens relie horizontalement les deux barres 6, et un volant 8, solidaire de la tige 7, permet par sa manoeuvre de régler l'écartement des barres 6, donc la déformation des systèmes - articulés 5a, 5b, et, par là, la hauteur de la table 4.A two-way threaded rod 7 connects horizontally the two bars 6, and a flywheel 8, integral with the rod 7, makes it possible, by its maneuver, to adjust the spacing of the bars 6, thus the deformation of the articulated systems 5a, 5b, and , by this, the height of the table 4.

La table 4 comprend des appuis latéraux 9 qui supportent une tablette 10 sur laquelle est fixé, par l'intermédiaire d'un support adéquat 11, un porte-outil rotatif -12. Il s'agit d'une perceuse pneumatique à commutateur manuel 13 de mise en fonctionnement et à inversion de marche au moyen d'un autre commutateur non représenté. Elle est alimentée en air comprimé par le rac cord souple 14, relié, au travers d'un ensemble purgeurdétendeur-huileur disposé sur le coté du dispositif 1 (non visible sur la figure 1), à un circuit d'air comprimé extrieur.  The table 4 comprises lateral supports 9 which support a tablet 10 on which is fixed, by means of a suitable support 11, a rotary tool holder -12. It is a pneumatic drill with manual switch 13 for operation and reversing by means of another not shown switch. It is supplied with compressed air by the flexible cable 14, connected through an exhaust-expander-oiler assembly disposed on the side of the device 1 (not visible in Figure 1) to an external compressed air circuit.

On a adapté sur la perce.use 12 deux manches solides- 15 (dont l'un est traversé par le raccord d'alimentation en air comprimé) pour que l'opérateur puisse tenir des deux mains la machine pendant le fonctionnement. Two solid sleeves 15 (one of which is traversed by the compressed air supply connector) have been fitted to the borehole 12 so that the operator can hold the machine with both hands during operation.

Un manchon 16 comporte une extrémité en cone morse lui permettant de s'emboîter dans le corps de la perceuce 12. Son autre extrémité est conformée pour pouvoir coiffer une manivelle 17 de manoeuvre du toit. Ladite extrémité comprend à cette fin une pièce radiale 18en U > venant enserrer le bras de la manivelle 17, soudée à un secteur tubulaire 19 qui vient coiffer l'extrémité de l'axe de la manivelle 17. Une équerre 20 soudée au manchon 16 et à la pièce en U 18 assure la solidité de l'assemblage. A sleeve 16 has a tapered end Morse allowing it to fit into the body of the bore 12. Its other end is shaped to be able to cap a crank 17 for maneuvering the roof. Said end comprises for this purpose a radial piece 18en U> coming to grip the arm of the crank 17, welded to a tubular sector 19 which caps the end of the axis of the crank 17. A bracket 20 welded to the sleeve 16 and to the U-shaped part 18 ensures the strength of the assembly.

Le dispositif de l'invention comporte encore deux poignées latérales 21 permettant de bien tenir la table pour la déplacer. La machine s'immobilise au sol par pression des pieds 22 de l'opérateur sur une barre 23 faisant office de sabot de frein ; la barre étant montée mobile verticalement grâce à des tiges 24 coulissant dans des corps, 25 fixés sur le chassis 2 et comportant des ressorts rappelant la barre 23 vers le haut. The device of the invention further comprises two lateral handles 21 to hold the table to move it. The machine stops at the ground by pressing the feet 22 of the operator on a bar 23 acting as a brake shoe; the bar being mounted vertically movable with rods 24 sliding in bodies, 25 fixed on the frame 2 and having springs recalling the bar 23 upwards.

Le fonctionnement de. l'ensemble est le suivant
L'opérateur vient placer le- çhassis devant la manivelle, en le déplaçant sur ses roulettes. Ensuite, il règle la hauteur de la table au moyen du volant situé devant lui , de façon à placer le manchon au niveau de la manivelle, compte-tenu de sa hauteur par rapport au quai ou au sol sur lequel se trouve le dispositif de l'invention, et il vient coiffer la manivelle par l'extrémité du manchon 16. Il immobilise le dispositif au sol par son frein 23 et procède à l'enroulement ou au déroulement du toit.The operation of. the whole is the following
The operator places the chassis in front of the crank, moving it on its wheels. Then, he adjusts the height of the table by means of the steering wheel in front of him, so as to place the sleeve at the level of the crank, taking into account its height with respect to the platform or the ground on which is located the device of the invention, and it comes to cap the crank by the end of the sleeve 16. It immobilizes the device on the ground by its brake 23 and proceeds to winding or unwinding the roof.

Des expériences ont montré que la manoeuvre d'ouverture ou de fermeture d'un type de wagon qui demandait 5 minutes à la main, steffectue désormais sans effort et sans danger en t min. 10s, à la satisfaction du personnel qui voit ainsi s'améliorer grandement ses conditions de travail et de sécurité.  Experiments have shown that the opening or closing maneuver of a type of wagon which required 5 minutes in the hand, now proceeds without effort and without danger in t min. 10s, to the satisfaction of the staff who thus see greatly improve their working conditions and safety.
