Description

Appareil de levage pour vehicules. 0n connait dejä des appareils de levage pour vdhicules constituds par un bäti aux montants duquel est suspendu un pont des tin6 ä supporter 1e vdhicule Pendant 1e levage. Dans des appareils de ce genre, tels que ddcrits dann 1e brevet suisse n 194534, 1e pont est suspendu ä des cäbles ou des chaines Passant sur des galets de chaque montant du bäti et s'enroulant sur des tam- bours d'un arbre moteur. Lifting device for vehicles. There are already known lifting devices for vehicles consisting of a frame from the uprights of which is suspended a bridge intended to support the vehicle during lifting. In devices of this type, as described in Swiss Patent No. 194534, the bridge is suspended from cables or chains passing over rollers on each upright of the frame and winding around the drums of a motor shaft. .

Les appareils de ce genre sont de cons- truction simple et peu coi'tteuse, et rdpondent parfaitement aux exigences courantes tant qu'il s'agit de vdhicules de poids relative- ment peu dleve, mais leur utilisation ne peut pas eire envisagde pour 1e levage de vdhicules dits poids lourds, tels que Camions, Cars, etc. Devices of this type are of simple and inexpensive construction, and perfectly meet current requirements as long as relatively low weight vehicles are concerned, but their use cannot be envisaged for the lifting of so-called heavy vehicles, such as Trucks, Cars, etc.

La prdsente inverition a pour objet un appareil de levage prdvu essentiellement pour des vdhicules poids lourds comportant comme les appareils connus quatre montants relids rigidement les uns aux autres et ser- vant de guides ä. un support sur lequel doit reposer 1e vdhicule, mais il s'en distingue par 1e fait que chaque montant comprend un dispositif de levage agissant sur 1e sup- port du vehicule, ce dispositif dtant actionnd au sommet du montant sur lequel il est placd au moyen d'organes de transmission ä partir d'un organe moteur unique commun aux quatre dispositifs de levage. The subject of the present invention is a lifting device provided essentially for heavy vehicles comprising, like the known devices, four uprights rigidly connected to each other and serving as guides. a support on which the vehicle must rest, but it is distinguished by the fact that each upright comprises a lifting device acting on the vehicle support, this device being actuated at the top of the upright on which it is placed by means of of transmission members from a single motor member common to the four lifting devices.

Le dessin annexd reprdsente, ä titre d'exemple et schematiquement, une forme d'exdcution de 1'objet de 1'invention en perl- pective. The attached drawing represents, by way of example and schematically, one form of execution of the object of the invention in perspective.

Comme an 1e voit, 1'appareil comporte quatre montants tubulaires 1 relids rigide- ment entre eux par leur Partie supdrieure au moyen de tubes 2. Chaque montant com- Porte ä sa base une Plaque de fixation 3. Le support sur lequel doit reposer le vdhi- cule est constitud par deux traverses 4 sur lesquelles sont places amoviblement deux longerons 5, de sorte que leur ecartement peut etre rdgld ä volontd. As can be seen, the apparatus comprises four tubular uprights 1 rigidly connected to each other by their upper part by means of tubes 2. Each upright comprises at its base a fixing plate 3. The support on which the vehicle is constituted by two crosspieces 4 on which are removably placed two side members 5, so that their spacing can be adjusted as desired.

Les montants 1 sont ouverts sur prati- quement tonte leur longueur en 6 pour lais- ser passer les extrdmitds des traverses 4 ou leurs organes de liaison avec des écrous 7 qui sont en prise chacun avec une vis 8 disposée dans le montant et suspendue dans la partie supérieure de ce dernier. Chaque vis 8 porte à son extrémité supérieure une roue d'angle 9 avec laquelle est en prise un pignon d'angle 10 d'un arbre de transmis sion 11, dont les paliers ne sont pas repré sentés pour la clarté du dessin. Sur un des tubes de liaison 2 est monté un support 12 pour un moteur 13 et un réducteur de vitesse 14 commandant un arbre 15 dont chaque extrémité porte un pignon d'angle 16 en prise avec la roue d'angle 9 d'un montant. Pour plus de simplicité les paliers de l'arbre 15 ne sont pas représentés. The uprights 1 are open over practically their entire length at 6 to allow the ends of the crosspieces 4 or their connecting members to pass with nuts 7 which are each engaged with a screw 8 arranged in the upright and suspended in the upper part of it. Each screw 8 carries at its upper end an angle wheel 9 with which an angle pinion 10 of a transmission shaft 11 engages, the bearings of which are not shown for the sake of clarity of the drawing. On one of the connecting tubes 2 is mounted a support 12 for a motor 13 and a speed reducer 14 controlling a shaft 15, each end of which carries a bevel pinion 16 engaged with the bevel wheel 9 of an upright. For simplicity the bearings of the shaft 15 are not shown.

Le fonctionnement de cet appareil se comprend sans autre. Le mouvement de l'arbre moteur 15 commande celui des roues d'angle 9 des deux montants voisins et ce mouvement est transmis aux roues d'angle 9 des deux autres montants par les arbres 11 et les pignons 10. La rotation des roues d'angle 9 commande celle des quatre vis 8 correspondantes de chaque montant et sui vant le sens de rotation les écrous 7 et, par conséquent, le support 4, 5 s'élève ou des cend entre les quatre montants. The operation of this device is easily understood. The movement of the motor shaft 15 controls that of the corner wheels 9 of the two neighboring uprights and this movement is transmitted to the corner wheels 9 of the two other uprights by the shafts 11 and the pinions 10. The rotation of the wheels of angle 9 controls that of the four screws 8 corresponding to each upright and following the direction of rotation of the nuts 7 and, consequently, the support 4, 5 rises or falls between the four uprights.

De préférence, la liaison des traverses 4 avec les écrous 7 est réalisée par une arti culation universelle. Le bâti de l'appareil, c'est-à-dire les mon tants 1 et les organes de liaison entre leur partie supérieure pourraient n'être pas cons titués par des tubes, ruais par d'autres pro filés appropriés. Comme le bâti ne comporte pas de tube 2 à l'extrémité opposée à celle comportant le moteur 13, on peut placer sur l'appareil des véhicules plus longs que la plus grande distance entre les montants 1 sans risquer lors du levage de venir cri con tact avec le cadre supérieur. Preferably, the connection of the crosspieces 4 with the nuts 7 is made by a universal joint. The frame of the device, that is to say the amounts 1 and the connecting members between their upper part could not be constituted by tubes, but by other appropriate profiles. As the frame does not comprise a tube 2 at the end opposite that comprising the motor 13, vehicles longer than the greatest distance between the uprights 1 can be placed on the device without risking, during lifting, coming cry con tact with the senior executive.

Au lieu de vis pendantes 8, on pourrait aussi prévoir que les extrémités des traver ses 4 soient fixées à des crémaillères com mandées par des pignons correspondants des arbres 11 et 15. II est clair, que soit l'arbre moteur 15, soit les arbres 11 pourraient être logés éga lement dans des tubes. Instead of pendent screws 8, provision could also be made for the ends of the traverses 4 to be fixed to racks controlled by corresponding pinions of the shafts 11 and 15. It is clear that either the motor shaft 15 or the shafts 11 could also be housed in tubes.

On pourrait naturellement aussi dans certains cas prévoir une traverse 2 pour relier les deux montants avant. One could of course also in some cases provide a crosspiece 2 to connect the two front uprights.

Le moteur et le démultiplicateur 14 pour raient aussi être montés contre l'un des montants 1 au lieu de l'être sur une tra verse 2. The motor and the reduction gear 14 could also be mounted against one of the uprights 1 instead of being on a crosspiece 2.
