Abstract

Extendable telescopic crane with crane operator's cab (4) which with a fastening part (5) can alternatively be fastened to the top end of the bottom, fixed, outer mast part (2) or the top end of the extendable, inner, top mast part (3). The fastening part (5) fastened to the cab (4) consists of a vertical flat steel bar with a vertically running elongated hole (6), a bore (7), and a dovetail slot (8) open at the edge. The flat bar can be mounted between a bracket attached to the top end of the bottom mast (2) or a bracket attached to the top end of the top mast (3) on a fixed pivot (11) on the supporting device (9) of the bottom mast (2) and can be held in place with a removable pivot (14) which is also used for fastening to the bracket of the top mast (3).

Description

La présente invention a pour objet une grue télescopique qui comporte une cabine de grutier pouvant être à volonté fixée soit à l'extrémité du mât extérieur fixe, soit à l'extrémité du mât intérieur télescopique. The present invention relates to a telescopic crane which comprises a crane operator's cabin which can be fixed at will either at the end of the fixed outer mast or at the end of the telescopic inner mast.

Les cabines de grues télescopiques de grande hauteur sont, dune manière générale, fixées au voisinage du sommet du mât supérieur des éléments télescopiques, l'accès à ces cabines s'effectuant par une échelle, également télescopi- que, fixée de préférence à l'intérieur des mâts, se déployant au fur et à mesure du télescopage des mâts. The cabins of very high telescopic cranes are generally fixed in the vicinity of the top of the upper mast of the telescopic elements, access to these cabins being effected by a ladder, also telescopic, preferably fixed to the inside of the masts, deploying as the masts telescoping.

La cabine se trouvant ainsi, immédiatement au niveau de floche, le grutier doit obligatoirement monter tout on haut ds la grue, alors que dans certains cas il pourrait avoir une aussi bonne vue panoramique du chantier dans une position à mi-mâture
La présente invention permet de fixer la cabine en deux positions différentes suivant les besoins du chantier.-
A titre d'exemple et pour faciliter la compréhension de l1invention, on a représenté aux dessins annexés
Figure 1 une vue schématique d'une grue télescopique à deux mâts, en position rentrée
Figure 2 une vue de la grue de la figure 1 en posi- tion dressée, la cabine étant en position intermédiaire
Figure 3 une vue de la grue de la figure 1 en position dressée, la cabine étant en position haute
Figure 4 une vue de détail à échelle agrandie illustrant la fixation de la cabine au mât télescopique
Figure 5 une vue correspondant à la figure 4 illass trant le transfert de la fixation de la cabine du mât téles- copique au mât fixe.
The cabin being thus, immediately at the level of the spindle, the crane operator must obligatorily go up very high of the crane, whereas in certain cases he could have as good a panoramic view of the building site in a position at half mast
The present invention makes it possible to fix the cabin in two different positions according to the needs of the site.
By way of example and to facilitate understanding of the invention, there is shown in the accompanying drawings
Figure 1 a schematic view of a telescopic crane with two masts, in the retracted position
Figure 2 a view of the crane of Figure 1 in the upright position, the cabin being in the intermediate position
Figure 3 a view of the crane of Figure 1 in the upright position, the cabin being in the high position
Figure 4 a detail view on an enlarged scale illustrating the attachment of the cabin to the telescopic mast
Figure 5 a view corresponding to Figure 4 illustrating the transfer of the attachment of the cabin from the telescopic mast to the fixed mast.

En se reportant à ces figures et notamment aux figures 1 à 3, on voit que la grue peut astre une grue télescopique quelconque et quelle comporte un socle 1, un mât inférieur, extérieur, fixe 2 et un mât supérieur, intérieur, mobile 3 qui coulisse télescopiquement dans le mât 2. Referring to these figures and in particular to Figures 1 to 3, it can be seen that the crane can be of any telescopic crane and which comprises a base 1, a lower mast, exterior, fixed 2 and an upper mast, interior, mobile 3 which slides telescopically into the mast 2.

Cette grue comporte une cabine de grutier 4 qui comporte des moyens de fixation par lesquels elle peut etre fixée à volonté, soit à l'extrémité supérieure du mât, 22 soit à l'extrémité supérieure du mât 3, le transfert d1une fixation à l'autre se faisant d'une façon très simple. This crane comprises a crane operator's cabin 4 which comprises fixing means by which it can be fixed at will, either at the upper end of the mast, 22 or at the upper end of the mast 3, the transfer from a fixing to the other being done in a very simple way.

En se reportant aux figures 4 et 5, on voit que la partie supérieure 4a de la cabine 4 comporte au moins une et de préférence deux pièces de fixation 5, chacune étant constituée par un fer plat muni, en partant du haut vers le bas d'une fenêtre oblongue 6, dtun orifice 7 et d'une fente en queue d'aronde 8. L'extrémité supérieure du mât 2 comporte une potence constituée par deux pattes 9, placées cote à cote, comportant, du haut vers le bas t un orifice 10 et un axe 11, la distance entre les centres géométriques de ltorig fice 10 et de l'axe il étant égale à celle séparant le centre de l'orifice 7 et le centre de l'arrondi situe au fond de la fente 8.L'extrémité supérieure du mât 3 comporte une potence constituée de manière analogue par deux pattes 12 comportant un orifice 13. Referring to Figures 4 and 5, we see that the upper part 4a of the cabin 4 comprises at least one and preferably two fixing parts 5, each consisting of a flat iron provided, starting from the top to the bottom d 'an oblong window 6, dtun orifice 7 and a dovetail slot 8. The upper end of the mast 2 comprises a bracket constituted by two legs 9, placed side by side, comprising, from top to bottom t an orifice 10 and an axis 11, the distance between the geometric centers of the origin 10 and of the axis it being equal to that separating the center of the orifice 7 and the center of the rounding situated at the bottom of the slot 8 .The upper end of the mast 3 comprises a bracket similarly constituted by two legs 12 having an orifice 13.

La distance séparant les pattes 9 ou 12 est légere- ment supérieure à ltepaisseur des fers plats 5, de sorte que ceux-ci peuvent venir s 'insérer entre ceux-là. The distance separating the legs 9 or 12 is slightly greater than the thickness of the flat bars 5, so that these can be inserted between them.

A la figure 4, la cabine 4 est fixée à ltexirémité supérieure du mât 3 au moyen d'un axe amovible 14 qui passe à travers les deux orifices 13 des pattes 12 et la fenêtre oblongue 6. In FIG. 4, the cabin 4 is fixed to the upper end of the mast 3 by means of a removable pin 14 which passes through the two orifices 13 of the tabs 12 and the oblong window 6.

Lorsqu'on fait descendre le mât télescopique 3, la fente 8 vient chevaucher l'axe il jusqutà ce que le fond de la fente 8 repose contre l'axe 11 ; la cabine 4 est alors portée par ledit axe il (ou les axes 11 quand il y en a plusieurs) et tandis que le mouvement de descente du mât 3 continue, la cabine 4 demeure immobile et l'axe 14 se déplace dans la fenêtre oblongue 6, les différents éléments venant occuper les positions respectives illustrées à la figure 5. When the telescopic mast 3 is lowered, the slot 8 straddles the axis il until the bottom of the slot 8 rests against the axis 11; the cabin 4 is then carried by said axis it (or the axes 11 when there are several) and while the downward movement of the mast 3 continues, the cabin 4 remains stationary and the axis 14 moves in the oblong window 6, the various elements coming to occupy the respective positions illustrated in FIG. 5.

Il suffit alors d'enlever l'axe 14 des orifices 13, 'ce qui est facile puisqutil est libéré de tout effort pour le placer dans les orifices 10, ce qui solidarise le fer plat 5 des deux pattes 9 : la cabine est alors fixée au sommet du mat 2 et non plus au sommet du mât 3 comme cela est représenté à la figure 2.It then suffices to remove the axis 14 from the holes 13, 'which is easy since it is freed from any effort to place it in the holes 10, which secures the flat iron 5 of the two legs 9: the cabin is then fixed at the top of the mast 2 and no longer at the top of the mast 3 as shown in FIG. 2.

On peut disposer des patins 15 à la base de la cabine 4 pour guider son mouvement de glissement. Skids 15 can be placed at the base of the cabin 4 to guide its sliding movement.
