Abstract
Description
La présente invention concerne généralement et a essentiellement pour objet un dispositif de levage ou analogue, en particulier pour utilisation sur des systèmes flottants tels que par exemple des grues flottantes et sur des plates'formes installées dans 1 t eau, du type comportant un mat de charge portant le palan de charge et prenant appui en bas dans un palier de l'aiguillot ou du vit de mulet du mât et qui est maintenu par des palans de pantoire ou de brassage fixés à des poteaux ou montants, en étant susceptible de pivoter et de passer en oscillant entre les poteaux ou montants, le mât de charge présentant, à son bout, un cercle de pantoire et/ou éventuellement un cercle, anneau ou couronne de charge, pouvant tourner de 3600 autour de l'axe longitudinal du mât de charge et à oeillets de fixation pour les palans de pantoire et de charge. L'invention se rapporte également aux diverses applications et utilisations résultant de la mise en oeuvre de ce dispositif ainsi qu'aux appareils, engins, véhicules, équipements et installations qui en sont pourvus. The present invention generally relates and essentially relates to a lifting device or the like, in particular for use on floating systems such as for example floating cranes and on platforms installed in 1 t water, of the type comprising a mast of load carrying the load hoist and bearing down in a bearing of the spur or the mullet's lifter of the mast and which is maintained by pantry or stirrup hoists fixed to posts or uprights, being capable of pivoting and to pass by oscillating between the posts or uprights, the load mast having, at its end, a circle of pantoire and / or possibly a circle, ring or crown of load, being able to turn by 3600 around the longitudinal axis of the mast load and fastening eyelets for pantry and load hoists. The invention also relates to the various applications and uses resulting from the implementation of this device as well as to the apparatuses, machines, vehicles, equipment and installations which are provided with them.
En partant d'un dispositif de levage tel que décrit précédemment, l'invention est basée sur le problème de conserver le principe du mât dit Sttllcken mais en pouvant cependant faire pivoter la charge de 3600 comme dans le cas digne grue tournante ou pivotante. Starting from a lifting device as described above, the invention is based on the problem of retaining the principle of the so-called Sttllcken mast but, however, being able to pivot the load of 3600 as in the case of a worthy rotating or pivoting crane.
Ce problème est résolu conformément à l'invention par le fait que trois poteaux ou montants sont placés au sommet ou angles d'un triangle fictif placé horizontalement autour du palier d'aiguillot ou de vit de mulet et sont reliés au cercle de pantoire par trois palans de pantoire. This problem is solved in accordance with the invention by the fact that three posts or uprights are placed at the top or angles of a fictitious triangle placed horizontally around the spur or mule landing and are connected by three to the pantry circle. pantry hoists.
De cette manière, la charge peutpvoter seulement à l'aide des palans de pantoire de 3600 autour de la verticale passant par le palier d'aiguillot ou de vit de mulet du mât. Il en résulte alors le domaine de travail visible sur la figure 4. Par variation de l'agencement des poteaux et du mit de charge, le domaine de travail peut être adapté dans une large mesure aux désirs de l'utilisateur et entre aménagé de telle sorte que lton puisse faire pivoter la charge maximale. In this way, the load can be moved only with the aid of the 3600 pantier hoists around the vertical passing through the spur or mule landing of the mast. This then results in the work area visible in FIG. 4. By varying the arrangement of the posts and the load mit, the work area can be adapted to a large extent to the wishes of the user and between such arrangements so that lton can rotate the maximum load.
Selon un autre développement de l'invention, 1 'anneau ou la couronne de charge est monté de façon tournante sur l'extrémité, cdté bout de mât, du cercle de pantoire réalisé sous forme de manchon ou de douille ou bien est disposé au-dessus du cercle de pantoire susceptible de tourner sur le mat de charge, en étant rigidement relié audit mat. According to another development of the invention, the load ring or crown is rotatably mounted on the end, at the end of the mast, of the circle of pants produced in the form of a sleeve or socket or else is arranged at- above the panther circle capable of rotating on the load mat, being rigidly connected to said mat.
Au moyen de ces combinaisons, les forces, provenant du palan de charge et des palans de pantoire, sont introduites dans le mat, auquel cas les trois points dtattagae ou de liaison peuvent tourner autour du mat tandis que l'anneau ou la couronne de charge peut aussi avoir constamment la mme position que le mat. By means of these combinations, the forces coming from the load hoist and the pantry hoists are introduced into the mast, in which case the three dattattae or connecting points can rotate around the mast while the load ring or crown can also constantly have the same position as the mast.
Enfin, selon une autre proposition de l'invention chacun des palans de pantoire peut être raccordable temporairement à une installation de traction constante. Finally, according to another proposal of the invention, each of the pantry hoists can be temporarily connectable to a constant traction installation.
De cette manière est assuré que le mat, dans tous les mouvements de pivotement sous charge, est toujaioe maintenu seulement par deux palans de pantoire et est donc statiquement déterminé, tandis que le troisième palan de pantoire est emmené mais en étant, à tous moments, prêt à entrer en action. In this way it is ensured that the mast, in all pivoting movements under load, is always held only by two pantry hoists and is therefore statically determined, while the third pantry hoist is carried but being, at all times, ready to go into action.

In accordance with Figures I to 3, three posts 1, 2 and 3, placed in an inclined manner, maintain a load mit 4 with extension 4 'to the end of the mast 4 ", on the floating system A. The mast 4 is supported in a dtaiguillot or mule vit bearing 5 on an imaginary triangular surface 6 between the base or base points of the posts I to 3.
La figure 4 illustre, par une zone hachurée, le domaine balayé par le mât de charge 4 en tournant autour de la verticale x-x passant par le palier d'aiguillot 5. FIG. 4 illustrates, by a hatched area, the area swept by the load mast 4 while turning around the vertical x-x passing through the spur bearing 5.
Le mit de charge 4 est maintenu par trois palans de pantoire Il à 13 menant respectivement aux poteaux 1 à 3 et qui sont fixés , du côté du malt, à des oeillets 17 à 19 d'un cercle de pantoire 14 qui peut tourner autour du prolongement de mAt 4t et qui se meut sur des paliers 15 et 16 et supporte la couronne de charge 21 sur des paliers 22 et 23.The load mit 4 is held by three pantry hoists II to 13 leading respectively to the posts 1 to 3 and which are fixed, on the malt side, to eyelets 17 to 19 of a panther circle 14 which can rotate around the extension of mAt 4t and which moves on bearings 15 and 16 and supports the load crown 21 on bearings 22 and 23.
La charge 20 agit sur des oeillets 24 et 25 de l'anneau de charge 21. Conformément à la figure 7, l'anneau de charge 21' peut cependant aussi être rigidement relié au prolongement de mat 4' et recouvrir le cercle
de pantoire 14. The load 20 acts on the eyelets 24 and 25 of the load ring 21. In accordance with FIG. 7, the load ring 21 'can however also be rigidly connected to the mast extension 4' and cover the circle
pants 14.
