Abstract

The lift platform has a scissors type mechanism forming part of an integrated loading bridge, with the arms of the scissors each being secured to an interior frame forming the bridge. The free ends of the arms have wheels connected which support the platform as the arms move. The frame supports on one side landing (5) joints which are fixed to the internal end of one arm of the scissors mechanism. The angular movement of the loading bridge is controlled by a device secured to the upper ends of at least one arm of the scissors to permit extension and retraction of the arms. the bridge rests on the wheels (8) at its end positions.

Description

       

  
 



  Les plates-formes élévatrices à ciseaux sont un moyen très apprécié pour charger des marchandises depuis le sol au niveau d'un camion ou encore depuis un quai au niveau d'un camion ou même d'un étage à un niveau supérieur ou inférieur. 



  Cependant ce n'est que la différence de niveau vertical qui est ainsi vaincue. 



  D'autre part il existe des ponts de chargement qui sont ancrés dans le quai et dont la partie arrière reste toujours au même niveau que le quai, mais qui font un mouvement angulaire autour de leur axe arrière pour s'adapter au niveau d'un camion, tout en avançant une partie télescopique (9) qui se pose alors sur la plate-forme du camion. 



  Pour réunir ces deux propriétés - compensation verticale, avancement et liaison horizontale avec inclinaison angulaire ont été conçues des machines combinées, c.à.d. la superposition d'un pont de chargement sur une plat-forme, dont la première qualité est de compenser à la fois les différences de niveau entre quai et camion et de se poser sur celui-ci en créant un pont par inclinaison d'une part, et d'autre part, de pouvoir faire toute la course verticale entre quai et sol pour, par exemple, permettre à un élévateur ou des containers de descendre du quai jusqu'au sol. 



  L'inconvénient de ces dernières machines est leur hauteur de construction excessive car elles additionnent tout simplement la hauteur de construction de la plate-forme à celle du pont de chargement. En plus le coût élevé de ces constructions limite passablement leur emploi. 



  D'autres constructions prévoient le pont de chargement entre le système des ciseaux de la plate-forme ce qui a pour effet négatif supplémentaire une forte réduction de la largeur de passage sur le pont de chargement. 



  La plate-forme définie dans les revendications remédie à ces inconvénients. 



  Les dessins annexés illustrent à titre d'exemple une forme d'exécution de l'invention, dans lesquels: 
 
   La fig. 1 montre la machine dans sa position de repos. 
   La fig. 2 montre la machine dans la position de travail posée sur un camion plus haut que le quai. 
   La fig. 3 montre la machine en position de travail, mais posée sur un camion plus bas que le quai. La présente invention se compose d'un cadre inférieur (1), d'un système de genouillères type plate-forme élévatrice (2), et de la partie supérieure d'un pont de chargement (3). Le mouvement vertical - quai/sol - appelé course se fait alors par le système genouillères (2) actionné par des cylindres hydrauliques (4).

  La partie supérieure du pont de chargement (3) est articulée aux points fixes des ciseaux (5) pour permettre le mouvement angulaire du pont nécessaire à l'adaptation à la hauteur du camion ou du wagon tout en restant toujours avec sa partie arrière au niveau du quai (6). Le mouvement angulaire du pont de chargement (3) est réalisé par un dispositif supplémentaire (7) qui rallonge ou raccourcit selon besoin la longueur des ciseaux (2) de l'extrémité où sont disposés les galets (8), ce qui a pour effet que le pont de chargement (3) s'incline et pose sa partie antérieure (9) sur le camion (10). 
   La fig. 4 montre la possible exécution d'un agrégat d'entraînement.

   L'agrégat électro-hydraulique (11) nécessaire au fonctionnement de l'ensemble est composé d'un moteur électrique (12), d'une pompe hydraulique (13), d'un réservoir d'huile (14), de vannes de surcharge (15), de vannes de régulation de débit (16), de vannes de distribution (17) et de vannes à siège (18) pour assurer une position fixe de niveau. 
   La fig. 5 montre un possible tableau de commande d'une telle machine. Le dispositif électrique (19) prévoit la commande par bouton-poussoir (20) des différents mouvements, tout en assurant les verrouillages nécessaires pour éviter de fausses manÖuvres. Ce dispositif permet également la commande totalement automatique, par exemple au moyen d'un circuit électronique intégré. 
 



  
 



  Scissor lifts are a popular way to load goods from the ground at the level of a truck or from a quay at the level of a truck or even from a floor to a higher or lower level.



  However, it is only the difference in vertical level which is thus overcome.



  On the other hand there are loading bridges which are anchored in the quay and whose rear part always remains at the same level as the quay, but which make an angular movement around their rear axis to adapt to the level of a truck, while advancing a telescopic part (9) which then arises on the platform of the truck.



  To combine these two properties - vertical compensation, advancement and horizontal connection with angular inclination, combined machines were designed, i.e. the superimposition of a loading bridge on a platform, the first quality of which is to compensate both for the differences in level between quay and truck and to land on it by creating a bridge by tilting on the one hand , and on the other hand, to be able to make the entire vertical stroke between quay and ground to, for example, allow an elevator or containers to descend from the quay to the ground.



  The disadvantage of these latter machines is their excessive construction height because they simply add the construction height of the platform to that of the loading bridge. In addition, the high cost of these constructions considerably limits their use.



  Other constructions provide the loading bridge between the scissor system of the platform, which has the additional negative effect of greatly reducing the passage width on the loading bridge.



  The platform defined in the claims overcomes these disadvantages.



  The accompanying drawings illustrate by way of example an embodiment of the invention, in which:
 
   Fig. 1 shows the machine in its rest position.
   Fig. 2 shows the machine in the working position placed on a truck higher than the platform.
   Fig. 3 shows the machine in working position, but placed on a truck lower than the quay. The present invention consists of a lower frame (1), a lifting platform type knee system (2), and the upper part of a loading bridge (3). The vertical movement - platform / ground - called stroke is then done by the knee lever system (2) actuated by hydraulic cylinders (4).

  The upper part of the loading bridge (3) is articulated at the fixed points of the scissors (5) to allow the angular movement of the bridge necessary to adapt to the height of the truck or wagon while always remaining with its rear part at the level from the platform (6). The angular movement of the loading bridge (3) is achieved by an additional device (7) which lengthens or shortens as necessary the length of the scissors (2) from the end where the rollers (8) are arranged, which has the effect that the loading bridge (3) inclines and places its front part (9) on the truck (10).
   Fig. 4 shows the possible execution of a training aggregate.

   The electro-hydraulic unit (11) necessary for the operation of the assembly is composed of an electric motor (12), a hydraulic pump (13), an oil tank (14), valves overload (15), flow control valves (16), distribution valves (17) and seat valves (18) to ensure a fixed level position.
   Fig. 5 shows a possible control panel for such a machine. The electrical device (19) provides control by push-button (20) of the various movements, while ensuring the interlocks necessary to avoid false operations. This device also allows fully automatic control, for example by means of an integrated electronic circuit.
