Abstract

The mast (4) has a ballast jib (15) with a rigid jib arm (16) articulated around a vertical axis on the mast. A slanted tie rod (17) connects the mast to a vertical end cap (22) of the arm, where the cap carries a pulley (25) for the passage of a cable (41) utilizable for lifting a concrete ballast block (14). The arm is coupled to an oriented hydraulic jack (31) possessing power supply such as hydro-electric power station (36), for allowing the jib to be motorized, autonomous and dismountable. A gas spring (23) pivots a rigid bar (19) relative to the arm in a predetermined direction.

Description

La présente invention se rapporte, de façon générale, au domaine des grues de chantier repliables. Plus particulièrement, cette invention concerne, pour de telles grues, un ensemble constitué par le mât de grue et par une potence de lestage associée à ce mât, c'est-à-dire une potence prévue pour la mise en place et le retrait, sur le châssis de la grue, de blocs de lest empilables destinés à stabiliser et à équilibrer la grue en cours d'utilisation de celle-ci.The present invention relates, in general, to the field of folding cranes. More particularly, this invention relates, for such cranes, an assembly consisting of the crane mast and a weight bracket associated with the mast, that is to say a bracket provided for the introduction and withdrawal, on the frame of the crane, stackable ballast blocks for stabilizing and balancing the crane in use thereof.

Il est connu, d'une manière générale, de stabiliser une grue de chantier en empilant, sur son châssis fixe ou tournant, des blocs de lest en béton plus ou moins nombreux.It is generally known to stabilize a construction crane by stacking more or less concrete ballast blocks on its fixed or rotating chassis.

Dans le cas ici considéré des grues repliables, à montage automatisé, le mode de transport habituel de ces grues à l'état replié est le transport routier sur une remorque ou sur une semi-remorque, ce qui limite le poids total transportable. Ainsi, il est nécessaire de retirer le lest de la grue pour la transporter, et de remettre en place ce lest avant la mise en service de la grue. Ces opérations nécessitent de démonter ou remonter, un à un, les différents blocs de lest.In the case here considered folding cranes, automated assembly, the usual mode of transport of these cranes in the folded state is road transport on a trailer or a semi-trailer, which limits the total transportable weight. Thus, it is necessary to remove the ballast from the crane for transport, and to replace this ballast before commissioning the crane. These operations require dismantling or reassembly, one by one, the different ballast blocks.

Pour monter ou démonter les blocs de lest sans recourir à une grue auxiliaire indépendante de la grue concernée, diverses techniques ont déjà été proposées.To mount or dismount the ballast blocks without using an auxiliary crane independent of the crane concerned, various techniques have already been proposed.

Une première solution, divulguée dans le brevet français FR 2306927 au nom du Demandeur, consiste en une potence de lestage qui est montée sur la plateforme tournante de la grue, et qui est reliée par un mouflage à l'ensemble repliable constitué par le mât et la flèche de la grue. Ainsi, la potence de lestage utilise ici la force motrice de la grue habituellement utilisée pour le repliage et le dépliage de l'ensemble constitué par le mât et la flèche, et le dispositif ne peut être considéré comme autonome.A first solution, disclosed in the patent French FR 2306927 in the name of the Applicant, consists of a weight bracket that is mounted on the rotating platform of the crane, and which is connected by a halyard to the collapsible assembly constituted by the mast and the boom of the crane. Thus, the weight bracket uses here the driving force of the crane usually used for folding and unfolding the assembly consisting of the mast and the boom, and the device can not be considered as autonomous.

Une autre solution, décrite dans le brevet français FR 2490609 , consiste en une potence de lestage fixée au mât de la grue, à proximité de sa base, le mât étant ici télescopique. Le câble et le treuil qui commandent le télescopage du mât de la grue sont, dans ce cas, aussi utilisés pour actionner la potence et ainsi manipuler les blocs de lest. Là aussi, le dispositif n'est pas autonome. De plus il faut positionner les blocs de lest à la main.Another solution, described in the patent French FR 2490609 , consists of a ballast bracket attached to the mast of the crane, near its base, the mast being here telescopic. The cable and the winch which control the telescoping of the mast of the crane are, in this case, also used to operate the stem and thus manipulate the ballast blocks. Here again, the device is not autonomous. In addition it is necessary to position the ballast blocks by hand.

On connaît également une grue à montage automatisé commercialisée par le Demandeur sous la dénomination IGO28, et décrite dans la documentation POTAIN 363-0200-032-0-FR, pourvue d'une potence de lestage dont le câble est mû par le treuil de levage de la grue, et qui est équipée d'un mécanisme d'orientation hydraulique. Le mécanisme d'orientation est relié à la centrale hydraulique de la grue, ce qui implique la réalisation d'un circuit hydraulique long et compliqué pour tenir compte du pliage de la grue et du télescopage du mât. De plus, le vérin d'orientation de la potence étant un vérin de petit diamètre alors que la centrale hydraulique de la grue est conçue pour délivrer un débit de fluide important nécessaire au relevage de la grue, le fonctionnement en rotation de la potence de lestage est peu progressif, ce qui nécessite d'installer un limiteur de débit.Also known is a self-erecting crane marketed by the Applicant under the name IGO28, and described in the documentation POTAIN 363-0200-032-0-FR, provided with a gallows weighting the cable is moved by the crane winch hoist, and which is equipped with a hydraulic steering mechanism. The steering mechanism is connected to the hydraulic power unit of the crane, which involves the realization of a long and complicated hydraulic circuit to take into account the folding of the crane and the telescoping of the mast. In addition, the steering cylinder of the stem being a small diameter cylinder while the hydraulic unit of the crane is designed to deliver a large fluid flow necessary to lift the crane, the rotating operation of the ballast bracket is somewhat progressive, which requires installing a flow limiter.

La présente invention vise à éliminer les inconvénients des diverses solutions connues, rappelées ci-dessus, et elle a donc pour but de fournir un dispositif qui permette d'automatiser au maximum le lestage d'une grue repliable du genre ici concerné, en évitant toute intervention manuelle pénible et dangereuse, et de rendre aussi la potence de lestage autonome, donc facilement démontable, et enfin de rendre le fonctionnement de cette potence plus progressif, notamment dans son mouvement d'orientation.The present invention aims at eliminating the disadvantages of the various known solutions mentioned above, and its purpose is therefore to provide a device which makes it possible to automate as much as possible the weighting of a folding crane of the kind in question here, avoiding any manual intervention painful and dangerous, and also make the gallows self-ballast, so easily removable, and finally make the operation of this gallows more progressive, especially in its orientation movement.

A cet effet, l'invention a essentiellement pour objet un mât de grue avec potence de lestage, notamment pour grue de chantier repliable, la potence de lestage prévue pour la manutention de blocs de lest étant, au moins en cours d'utilisation, fixée au mât ou à un élément de celui-ci, ladite potence de lestage comprenant un bras de potence articulé autour d'un axe vertical sur le mât, et un tirant qui relie le mât à l'extrémité antérieure du bras de potence, extrémité qui porte au moins une poulie pour le passage d'un câble utilisable pour le levage d'au moins un bloc de lest, cet ensemble étant caractérisé par le fait que, étant de conception autonome et démontable, le bras de potence est accouplé à un vérin d'orientation possédant une alimentation en énergie qui lui est propre.For this purpose, the subject of the invention is essentially a crane mast with a ballast bracket, in particular for a collapsible construction crane, the weighting bracket intended for the handling of ballast blocks being, at least during use, fixed. to the mast or to an element thereof, said weighting bracket comprising a jib arm articulated about a vertical axis on the mast, and a tie rod which connects the mast to the front end of the jib arm, end which carries at least one pulley for the passage of a cable usable for lifting at least one ballast block, this assembly being characterized by the fact that, being of autonomous and removable design, the stem arm is coupled to a jack orientation with a power supply of its own.

Dans un mode de réalisé préféré de l'invention, le vérin d'orientation est un vérin hydraulique, et son alimentation en énergie est réalisée par une centrale hydraulique appartenant à la potence de lestage. La centrale hydraulique peut être portée par l'extrémité postérieure du bras de potence, par exemple par une chape d'articulation prévue à cette extrémité du bras de potence.In a preferred embodiment of the invention, the steering cylinder is a hydraulic cylinder, and its power supply is performed by a hydraulic unit belonging to the ballast bracket. The hydraulic unit can be carried by the rear end of the stem arm, for example by a hinge yoke provided at this end of the stem arm.

Ainsi, le mouvement d'orientation de la potence de lestage est motorisé au moyen d'un vérin qui est rendu indépendant de la centrale hydraulique et du circuit hydraulique de la grue, notamment en utilisant une centrale hydraulique intégrée à la potence de lestage et dimensionnée en fonction des besoins en énergie de cette potence. Les flexibles hydrauliques qui relient la centrale au vérin d'orientation peuvent donc être très courts, et ce vérin fonctionne de façon très progressive. Dans la mesure où la centrale hydraulique est portée par le bras de potence, le démontage de la potence de lestage, c'est-à-dire sa séparation du mât de la grue, se trouve aussi facilité. La potence ainsi rendue facilement démontable peut être utilisée sur plusieurs grues identiques.Thus, the steering movement of the ballast bracket is motorized by means of a jack which is made independent of the hydraulic unit and the hydraulic circuit of the crane, in particular by using a integrated hydraulic power station at the weighting bracket and sized according to the energy requirements of this stem. The hydraulic hoses that connect the control unit to the orientation cylinder can therefore be very short, and this cylinder operates very gradually. As the hydraulic unit is carried by the jib arm, disassembly of the ballast bracket, that is to say its separation from the mast of the crane, is also facilitated. The stem thus made easily removable can be used on several identical cranes.

Selon une forme de réalisation avantageuse de l'invention, le tirant qui relie le mât de la grue à l'extrémité antérieure du bras de potence est composé d'un câble flexible attaché au mât de la grue, et d'une barre rigide qui prolonge le câble et qui est articulée à l'extrémité antérieure du bras de potence. Avantageusement, des moyens à ressort, tels qu'un ressort à gaz, sont associés à l'articulation de la barre rigide du tirant avec l'extrémité antérieure du bras de potence, lesdits moyens à ressort tendant à faire pivoter la barre relativement au bras de potence dans un sens prédéterminé. Grâce à ces dispositions, un repliage du tirant s'effectue et est même facilité, au cours du repliage de la grue, de manière à replier simultanément le bras de potence contre le mât de la grue.According to an advantageous embodiment of the invention, the tie rod which connects the mast of the crane to the front end of the stem arm is composed of a flexible cable attached to the mast of the crane, and a rigid bar which extends the cable and is hinged to the front end of the stem arm. Advantageously, spring means, such as a gas spring, are associated with the articulation of the rigid bar of the tie rod with the front end of the arm of the bracket, said spring means tending to rotate the bar relative to the arm of gallows in a predetermined direction. Thanks to these provisions, a folding of the tie is effected and is even easier, during the folding of the crane, so as to simultaneously fold the arm of the bracket against the mast of the crane.

The invention will be better understood from the description which quit, with reference to the attached schematic drawing showing, by way of example, an embodiment of the crane mast with ballast bracket.

La figure 1 représente, en vue de côté, une grue à tour repliable, qui comprend un châssis de base fixe 2, un châssis tournant 3 orientable relativement au châssis fixe 2, un mât 4 télescopique et rabattable réalisé en deux éléments 5 et 6, et une flèche repliable 7 réalisée, dans l'exemple considéré, en trois éléments de flèche successifs 8, 9 et 10. L'élément inférieur 5 du mât 4 est relié de façon articulée au châssis tournant 3 par deux haubans avant 11 et par deux haubans arrière 12, tandis que l'extrémité arrière de la flèche 7 est articulée au sommet de l'élément supérieur 6 du mât 4. Un dispositif de retenue de flèche 13, ici non détaillé, maintient la flèche 7 en position horizontale, dans la position de travail de la grue c'est-à-dire lorsque le mât 4 est dressé à la verticale.The figure 1 represents, in side view, a folding tower crane, which comprises a fixed base frame 2, a rotating frame 3 which can be rotated relative to the fixed frame 2, a telescopic and foldable mast 4 made in two elements 5 and 6, and an arrow collapsible 7 made, in the example, in three successive deflection elements 8, 9 and 10. The lower element 5 of the mast 4 is hingedly connected to the rotating frame 3 by two front stays 11 and two rear shrouds 12 , while the rear end of the boom 7 is hinged to the top of the upper element 6 of the mast 4. An arrow retainer 13, here not detailed, holds the boom 7 in the horizontal position, in the working position crane that is to say when the mast 4 is erected vertically.

En position dépliée de travail, la grue est stabilisée et équilibrée par un lest qui résulte de l'empilement, sur le châssis tournant 3, d'un certain nombre de blocs de lest 14 en béton, dont l'un est représenté (en cours de manutention) sur la figure 5. Pour mettre en place les blocs de lest 14 avant la mise en service de la grue, et pour retirer ces blocs de lest 14 avant repliage et transport de la grue, il est prévu une potence de lestage 15 qui est associée au mât 4 et, plus particulièrement, à l'élément inférieur 5 de ce mât.In the unfolded working position, the crane is stabilized and balanced by a ballast which results from the stacking, on the rotating frame 3, of a number of concrete ballast blocks 14, one of which is shown (in progress handling) on the figure 5 . To set up the ballast blocks 14 before the crane is put into service, and to remove these ballast blocks 14 before folding and transporting the crane, a ballast bracket 15 is provided which is associated with the mast 4 and, more particularly, to the lower element 5 of this mast.

Les figures 2, 3 et 4 représentent, plus particulièrement, la structure de la potence de lestage 15.The figures 2 , 3 and 4 represent, in particular, the structure of the weighting bracket 15.

Cette potence de lestage 15 comprend un bras de potence 16 rigide, dont l'extrémité postérieure est liée de façon articulée à l'élément de mât 5, et dont l'extrémité antérieure est reliée par un tirant oblique 17 au même élément de mât 5.This weighting bracket 15 comprises a rigid stem arm 16 whose rear end is hingedly connected to the mast element 5 and whose front end is connected by an oblique tie rod 17 to the same mast element 5. .

Le tirant 17 est composé d'un câble flexible 18 et d'une barre rigide 19. Le câble 18 est attaché en un point fixe 20 à l'élément de mât 5, dans la partie supérieure de cet élément de mât. La barre 19, qui prolonge le câble 18, est articulée autour d'un axe horizontal 21 sur une chape terminale verticale 22 du bras de potence 16. L'extrémité de la barre 19, qui s'étend au-delà de l'axe 21, est reliée par un ressort à gaz 23 à un point de la chape terminale 22. Cette chape terminale 22 du bras de potence 16 porte un axe horizontal 24, sur lequel est montée librement tournante une première poulie 25 (voir en particulier la figure 3).The tie rod 17 is composed of a flexible cable 18 and a rigid bar 19. The cable 18 is attached at a fixed point 20 to the mast element 5, in the upper part of this mast element. The bar 19, which extends the cable 18, is articulated about a horizontal axis 21 on a vertical end cap 22 of the stem arm 16. The end of the bar 19, which extends beyond the axis 21, is connected by a gas spring 23 to a point of the end yoke 22. This end cap 22 of the jib arm 16 carries a horizontal axis 24, on which is mounted freely rotatable a first pulley 25 (see in particular the figure 3 ).

A son extrémité postérieure (voir en particulier la figure 4), le bras de potence 16 comporte une autre chape verticale 26, qui est articulée par un axe horizontal 27 sur un support 28, lui-même monté pivotant suivant un axe vertical 29 sur l'élément de mât inférieur 5, à proximité de l'une des membrures d'angle 30 de cet élément de mât 5.At its posterior end (see in particular the figure 4 ), the jib arm 16 comprises another vertical clevis 26, which is articulated by a horizontal axis 27 on a support 28, itself pivotally mounted along a vertical axis 29 on the lower mast element 5, close to the one of the corner members 30 of this mast element 5.

Un vérin hydraulique d'orientation 31, disposé horizontalement sur un côté de l'élément de mât 5, possède un corps de vérin 32 articulé en un point fixe 33 de cet élément de mât 5, et une tige de vérin 34 qui est articulée en un point 35 sur un bras latéral du support pivotant 28.A hydraulic steering cylinder 31, arranged horizontally on one side of the mast element 5, has a cylinder body 32 articulated at a fixed point 33 of this mast element 5, and a cylinder rod 34 which is hinged in a point 35 on a lateral arm of the pivoting support 28.

La chape 26 postérieure du bras de potence 16 porte, dans sa partie supérieure, une centrale hydraulique 36 qui comprend un groupe motopompe avec un moteur électrique alimenté en courant alternatif disponible sur la grue ou sur le chantier. Deux flexibles hydrauliques 37 et 38 relient la centrale hydraulique 36 aux deux chambres du vérin d'orientation 31. Ainsi, l'actionnement du vérin 31, réalisé comme un vérin à double effet, permet d'orienter le bras de potence 16 en faisant pivoter son support 28 dans un sens ou dans l'autre autour de l'axe vertical 29.The rear clevis 26 of the jib arm 16 carries, in its upper part, a hydraulic unit 36 which comprises a pump unit with an electric motor powered by alternating current available on the crane or on the construction site. Two hydraulic hoses 37 and 38 connect the hydraulic unit 36 to the two chambers of the orientation cylinder 31. Thus, the actuation of the cylinder 31, made as a double-acting cylinder, makes it possible to orient the stem arm 16 by rotating its support 28 in one direction or the other around the vertical axis 29.

La chape 26 postérieure du bras de potence 16 porte elle aussi un axe horizontal 39, sur lequel est montée librement tournante une seconde poulie 40.The rear clevis 26 of the jib arm 16 also carries a horizontal axis 39, on which is mounted freely rotating a second pulley 40.

Pour l'utilisation de la potence de lestage 15, comme l'illustrent la figure 3 et surtout la figure 5, un câble 41 passe sur les poulies 25 et 40, l'extrémité du câble 41 qui pend sous la première poulie 25 comportant un crochet 42 auquel peut être suspendu, par l'intermédiaire d'élingues 43, un bloc de lest 14.For the use of the weighting bracket 15, as illustrated by figure 3 and especially the figure 5 , a cable 41 passes over the pulleys 25 and 40, the end of the cable 41 which hangs under the first pulley 25 having a hook 42 to which can be suspended, by means of slings 43, a block of ballast 14.

Après son passage sur la seconde poulie 40 de la potence 15, le câble 41 est dirigé vers le bas, puis renvoyé vers le haut par deux autres poulies 44 et 45 situées dans la partie inférieure de l'élément de mât 5. Enfin, l'autre extrémité du câble 41 est reliée, ici par une poulie de mouflage 46, au câble de levage existant 47 de la grue, lequel s'enroule de façon connue autour d'un tambour d'un treuil de levage (non représenté). L'actionnement de ce treuil déplace le câble de levage 47, qui lui-même déplace le câble 41 de la potence de lestage 15, de manière à relever ou abaisser le bloc de lest 14 suspendu au crochet 42.After passing over the second pulley 40 of the bracket 15, the cable 41 is directed downwards and then returned upwards by two other pulleys 44 and 45 located in the lower part of the mast element 5. Finally, The other end of the cable 41 is connected here by a hauling pulley 46 to the existing hoisting rope 47 of the crane, which is wound in a known manner around a drum of a hoist winch (not shown). The actuation of this winch moves the hoisting rope 47, which itself moves the cable 41 of the weighting bracket 15, so as to raise or lower the ballast block 14 suspended from the hook 42.

Ainsi, l'actionnement combiné du treuil de levage, et du vérin d'orientation 31, permet de déplacer les blocs de lest 14 successivement, pour les empiler sur le châssis tournant 3 de la grue ou pour les retirer de ce châssis 3. En particulier, la potence de lestage 15 permet de retirer tous les blocs de lest 14, avant de procéder au repliage de la grue lui-même préalable au transport de la grue sur une remorque ou une semi-remorque.Thus, the combined operation of the hoist winch, and the orientation jack 31, makes it possible to move the ballast blocks 14 successively, for stack them on the rotating frame 3 of the crane or to remove them from this frame 3. In particular, the weighting bracket 15 makes it possible to remove all the ballast blocks 14, before proceeding to fold the crane itself prior to the transporting the crane on a trailer or semi-trailer.

En complément, les figures 6 et 7 illustrent, dans deux phases successives, le repliage de la grue qui s'accompagne ici d'un repliage de la potence de lestage 15. Pour le repliage de la grue, après avoir rétracté le mât 4 télescopique et avoir replié la flèche 7 sur elle-même et contre le mât 4, on fait basculer l'ensemble constitué par la flèche 7 et par le mât 4 sur l'arrière, c'est-à-dire vers le côté précédemment occupé par le lest, comme l'illustre la figure 6. Le bras de potence 16 vient alors en butée contre l'un des haubans arrière 12.In addition, Figures 6 and 7 illustrate, in two successive phases, the folding of the crane which is here accompanied by a folding of the weighting bracket 15. For folding the crane, after retracting the telescopic mast 4 and folding the arrow 7 on it -and even against the mast 4, we rock the assembly consisting of the arrow 7 and the mast 4 on the back, that is to say to the side previously occupied by the ballast, as illustrated by the figure 6 . The jib arm 16 then abuts against one of the rear shrouds 12.

Le mouvement de basculement se poursuivant, la barre rigide 19 du tirant 17, poussée par le ressort à gaz 23, tend à pivoter autour de l'axe 21 et vient finalement en butée sur le bras de potence 16, comme le montre la figure 7. Ensuite (d'une manière non représentée), le câble 18 du tirant 17 se détend, et l'on peut finalement terminer le repliage de la grue, le bras de potence 16 se plaçant parallèlement au mât 4 entièrement abaissé.As the tilting movement continues, the rigid bar 19 of the tie rod 17, pushed by the gas spring 23, tends to pivot about the axis 21 and finally comes into abutment on the jib arm 16, as shown in FIG. figure 7 . Then (in a manner not shown), the cable 18 of the tie rod 17 relaxes, and it is finally possible to complete the folding of the crane, the jib arm 16 being placed parallel to the mast 4 fully lowered.

On notera aussi que, si cela est désiré ou nécessaire, la potence de lestage 15 peut être rapidement démontée, c'est-à-dire séparée du mât 4 de la grue, puisqu'elle se trouve liée à ce mât 4 uniquement au niveau du point d'attache 20 du câble 18 et au niveau du vérin d'orientation 31, ceci au moyen d'axes de liaison.Note also that, if desired or necessary, the ballast bracket 15 can be quickly dismantled, that is to say separated from the mast 4 of the crane, since it is linked to the mast 4 only at the level the point of attachment 20 of the cable 18 and at the level of the steering cylinder 31, this by means of connecting pins.

Bien que l'invention ait été décrite et illustrée en relation avec une grue à mât 4 télescopique, on conçoit aisément que le même dispositif de potence de lestage 15 peut, de manière similaire, être monté sur l'élément inférieur d'un mât de grue repliable, c'est-à-dire un mât constitué de deux ou plusieurs éléments de mât superposés, articulés entre eux.Although the invention has been described and illustrated in connection with a telescopic mast crane 4, it is readily conceivable that the same ballast device 15 may similarly be mounted on the lower member of a mast. folding crane, that is to say a mast consisting of two or more mast elements superimposed, articulated between them.

  • en modifiant les détails de forme du dispositif, tels que les détails du bras de potence ;
  • en ayant recours à tous moyens équivalents de ceux précédemment décrits, ceci concernant notamment le type d'énergie utilisable par le vérin d'orientation de la potence de lestage ; en particulier, si cette potence est prévue démontable, la seule énergie utilisable est en pratique l'électricité et l'on peut donc aussi envisager ici l'utilisation d'un vérin électrique ;
  • en destinant une telle potence de lestage à des grues de tous types, et en utilisant cette potence avec tous moyens de suspension ou de préhension des blocs de lest à manipuler.
