Description

La présente invention concerne le domaine de la construction de grues, en particulier de grues repliables et, notamment, les flèches télescopiques de telles grues et a pour objet une telle flèche télescopique.The present invention relates to the field of crane construction, in particular folding cranes and, in particular, the telescopic jibs of such cranes and relates to such a telescopic jib.

Les grues repliables, qui sont généralement destinées à être montées sur des camions ou des tracteurs de semi-remorques ou analogues ou sur certains engins de manutention, sont constituées par un bras de support fixé à pivotement sur un fût rotatif et muni à son autre extrémité d'une articulation de réception d'un bras repliable logeant un élément télescopique portant à son extrémité libre une griffe à actionnement hydraulique, ou analogue.Foldable cranes, which are generally intended to be mounted on trucks or tractors of semi-trailers or the like or on certain handling equipment, consist of a support arm pivotally attached to a rotary drum and provided at its other end an articulation for receiving a folding arm housing a telescopic element carrying at its free end a claw with hydraulic actuation, or the like.

Les moyens d'actionnement hydraulique d'une griffe ou autre sont raccordés, en tête de l'élément télescopique, à des conduites de distribution de fluide.The hydraulic actuating means of a claw or the like are connected, at the head of the telescopic element, to fluid distribution pipes.

Actuellement, ces conduites se présentent généralement sous forme de conduites rigides, fixées extérieurement au bras de support et au bras repliable et reliées à des raccords prévus sur des platines d'extrémité de l'élément télescopique au moyen de conduites flexibles permettant la sortie dudit élément télescopique.Currently, these pipes are generally in the form of rigid pipes, fixed externally to the support arm and to the foldable arm and connected to fittings provided on end plates of the telescopic element by means of flexible conduits allowing the exit of said element. telescopic.

Ces conduites flexibles s'étendent entre les extrémités du bras repliable et de l'élément télescopique et pendent entre elles en position rétractée dudit élément télescopique.These flexible pipes extend between the ends of the folding arm and of the telescopic element and hang between them in the retracted position of said telescopic element.

Une telle constitution permet d'assurer correctement le fonctionnement de grues de ce type, mais présente l'inconvénient d'exposer les conduites flexibles aux risques de coincement par des charges manipulées ou encore de coincement lors du repliage du bras repliable contre le bras support, ainsi qu'à tous autres risques de détérioration accidentelle ou par malveillance.Such a constitution makes it possible to ensure the proper functioning of cranes of this type, but has the drawback of exposing the flexible pipes to the risks of jamming by manipulated loads or else of jamming during the folding of the folding arm against the support arm, as well as all other risks of accidental or malicious damage.

De plus, les conduites rigides sont également exposées à des risques d'écrasement, soit lors de la manutention, soit par chocs.In addition, rigid pipes are also exposed to the risk of crushing, either during handling or by impact.

Pour obvier à ces inconvénients, les conduites rigides ont été protégées par montage à l'intérieur du bras de support et sur le bras repliable avec prévision de rebords de protection et il a été proposé de loger les conduites souples dans un espace prévu dans le bras repliable entre au moins une paroi de celui-ci et l'élément télescopique, ces conduites souples étant disposées suivant une boucle dans ledit espace.To overcome these drawbacks, the rigid pipes have been protected by mounting inside the support arm and on the foldable arm with provision of protective flanges and it has been proposed to accommodate the flexible pipes in a space provided in the arm. foldable between at least one wall thereof and the telescopic element, these flexible pipes being arranged in a loop in said space.

Par FR-A-2 355 767 il a, par ailleurs, été proposé de munir l'élément télescopique d'une partie de guidage s'étendant le long d'une paroi dudit élément télescopique et entre les parois du bras repliable. L'espace ainsi délimité sert simultanément à la réception des conduites flexibles, de sorte que celles-ci sont protégées contre des détériorations, notamment en position de rétraction de l'élément télescopique.By FR-A-2 355 767 it has also been proposed to provide the telescopic element with a guide portion extending along a wall of said telescopic element and between the walls of the foldable arm. The space thus defined is used simultaneously for the reception of flexible pipes, so that they are protected against damage, in particular in the retracted position of the telescopic element.

Cependant, dans ce mode de réalisation, les conduites rigides reliées aux conduites flexibles doivent s'étendre extérieurement au bras repliable, de sorte qu'elles restent exposées à des risques d'écrasement ou autre.However, in this embodiment, the rigid pipes connected to the flexible pipes must extend externally to the foldable arm, so that they remain exposed to risks of crushing or the like.

En outre, la paroi formant réception des conduites flexibles, ne s'étend que sur une faible hauteur de la partie intérieure du bras repliable, de sorte qu'un coincement desdites conduites entre le rebord de cette paroi et la face interne du bras repliable reste possible, ce qui entraîne également une détérioration desdites conduites.In addition, the wall forming reception of the flexible conduits, extends only over a small height of the inner part of the foldable arm, so that jamming of said conduits between the edge of this wall and the internal face of the foldable arm remains possible, which also leads to deterioration of said pipes.

De plus, les conduites sont exposées à un frottement le long de la paroi interne du bras repliable et donc à une usure.In addition, the pipes are exposed to friction along the internal wall of the foldable arm and therefore to wear.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet une flèche télescopique de grue, en particulier de grue repliable, essentiellement constituée par un bras repliable monté à pivotement sur un bras support et logeant un élément télescopique actionné au moyen d'un vérin et pourvu à son extrémité libre d'un nez de fixation d'un élément de manutention ou analogue, caractérisée en ce que l'élément télescopique est sous forme d'un caisson guidé, sans prévision d'espace libre, dans le bras repliable et est muni à sa partie avant de platines de fixation de raccords hydrauliques des dispositifs d'actionnement de l'élément de manutention ou analogue, en ce que le bras repliable est fermé à sa partie arrière par une platine pourvue de raccords de branchement de conduites hydrauliques, et en ce que la liaison entre les raccords de branchement de la platine du bras repliable et des platines de l'élément télescopique est réalisée par l'intermédiaire de conduites s'étendant dans l'élément télescopique.It has, in fact, for its object a telescopic boom of a crane, in particular a foldable crane, essentially constituted by a foldable arm pivotally mounted on a support arm and housing a telescopic element actuated by means of a jack and provided at its end. free of a fixing nose of a handling element or the like, characterized in that the telescopic element is in the form of a guided box, without provision of free space, in the folding arm and is provided at its part front of fixing plates for hydraulic connections of the actuating devices of the handling element or the like, in that the folding arm is closed at its rear part by a plate provided with connection connections for hydraulic lines, and in that the connection between the connection fittings of the plate of the folding arm and of the plates of the telescopic element is carried out by means of pipes extending in the element telescopic.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale d'une grue à flèche télescopique conforme à l'invention ;
  • la figure 2 est une vue en perspective, à plus grande échelle, représentant le bras repliable et l'élément télescopique ;
  • la figure 3 est une vue analogue à celle de la figure 1, à plus grande échelle et en coupe, représentant le bras repliable et l'élément télescopique, et
  • la figure 4 est une vue en coupe suivant la figure 3.
The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a side elevational view of a telescopic jib crane according to the invention;
  • Figure 2 is a perspective view, on a larger scale, showing the folding arm and the telescopic element;
  • FIG. 3 is a view similar to that of FIG. 1, on a larger scale and in section, showing the folding arm and the telescopic element, and
  • FIG. 4 is a sectional view according to FIG. 3.

La figure 1 des dessins annexés représente une flèche télescopique de grue, en particulier de grue repliable, essentiellement constituée par un bras repliable 1 monté à pivotement sur un bras support 2 et logeant un élément télescopique 3 actionné au moyen d'un vérin 4 et pourvu à son extrémité libre d'un nez 5 de fixation d'un élément de manutention ou analogue.FIG. 1 of the appended drawings represents a telescopic boom of a crane, in particular of a folding crane, essentially constituted by a folding arm 1 pivotally mounted on a support arm 2 and housing a telescopic element 3 actuated by means of a jack 4 and provided at its free end with a nose 5 for fixing a handling element or the like .

Conformément à l'invention et comme le montrent les figures 1 à 4 des dessins annexés, l'élément télescopique 3 est sous forme d'un caisson guidé, sans prévision d'espace libre, dans le bras repliable 1 et est muni à sa partie avant de platines 6 de fixation de raccords hydrauliques 7 des dispositifs d'actionnement de l'élément de manutention ou analogue.According to the invention and as shown in Figures 1 to 4 of the accompanying drawings, the telescopic element 3 is in the form of a guided box, without provision of free space, in the folding arm 1 and is provided at its part before plates 6 for fixing hydraulic fittings 7 for actuating devices of the handling element or the like.

Le bras repliable 1 est fermé à sa partie arrière par une platine 8 pourvue de raccords 9 de branchement de conduites hydrauliques et la liaison entre les raccords de branchement 9 de la platine 8 de ce bras repliable 1 et des platines 6 de l'élément télescopique 3 est réalisée par l'intermédiaire de conduites 10 s'étendant dans ledit élément télescopique 3 (figure 1).The foldable arm 1 is closed at its rear by a plate 8 provided with connections 9 for connecting hydraulic lines and the connection between the connection connections 9 of the plate 8 of this foldable arm 1 and plates 6 of the telescopic element 3 is produced by means of pipes 10 extending in said telescopic element 3 (FIG. 1).

Selon une caractéristique de l'invention, les conduites 10 de liaison entre les raccords de branchement 7 et 9 peuvent se présenter sous forme de conduites flexibles s'étendant dans le caisson formant l'élément télescopique 3, de part et d'autre du vérin d'actionnement 4, suivant une boucle en S. Un tel mode de réalisation permet un montage simple des conduites 10 dans l'élément télescopique 3 par fixation aux raccords de branchement 7 et 9 correspondants.According to a characteristic of the invention, the connecting pipes 10 between the connection fittings 7 and 9 may be in the form of flexible pipes extending in the box forming the telescopic element 3, on either side of the jack actuation 4, in an S loop. Such an embodiment allows simple mounting of the pipes 10 in the telescopic element 3 by attachment to the corresponding connection fittings 7 and 9.

La figure 2 représente une variante de réalisation de l'invention dans laquelle les conduites 10 sont constituées par une combinaison de conduites flexibles 11 et de conduites rigides 12, ces conduites rigides 12 s'étendant le long d'une paroi de l'élément télescopique 3 et étant fixées à leurs extrémités, respectivement aux platines d'extrémité 6 prévues près du nez 5 et à des raccords 13 prévus sur des platines de support 14 fixées à l'autre extrémité de l'élément télescopique 3, les conduites flexibles 11 étant reliées, d'une part, aux raccords 9 de la platine 8 du bras repliable 1 et, d'autre part, aux raccords 13 des platines de support 14.FIG. 2 represents an alternative embodiment of the invention in which the pipes 10 are constituted by a combination of flexible pipes 11 and rigid pipes 12, these rigid pipes 12 extending along a wall of the telescopic element 3 and being fixed at their ends, respectively to the end plates 6 provided near the nose 5 and to connections 13 provided on support plates 14 fixed at the other end of the telescopic element 3, the flexible pipes 11 being connected, on the one hand, to the connections 9 of the plate 8 of the folding arm 1 and, on the other hand part, to the connections 13 of the support plates 14.

Ainsi, une partie du circuit hydraulique de distribution pourra être réalisée de manière rigide par des conduites 12 fixées directement contre une paroi et ne risquant pas de subir une détérioration par usure suite au frottement ou par fatigue et la partie formée par les conduites flexibles 11 pourra être limitée à la longueur nécessaire au déploiement complet de l'élément télescopique 3, ces conduites flexibles 11 pouvant également être facilement démontées en cas de besoin. A cet effet, l'élément télescopique 3 peut être pourvu, de manière connue en soi, à hauteur du raccordement de l'extrémité des conduites 11 avec les raccords 13 des platines de support 14 d'une fenêtre d'intervention non représentée.Thus, part of the hydraulic distribution circuit can be made rigidly by pipes 12 fixed directly against a wall and not likely to be damaged by wear due to friction or by fatigue and the part formed by flexible pipes 11 may be limited to the length necessary for the complete deployment of the telescopic element 3, these flexible pipes 11 can also be easily disassembled if necessary. To this end, the telescopic element 3 can be provided, in a manner known per se, at the height of the connection of the end of the pipes 11 with the connections 13 of the support plates 14 of an intervention window not shown.

Selon une caractéristique de l'invention, les conduites flexibles 11 peuvent s'étendre de part et d'autre du vérin 4 sans prévision d'un guidage particulier. Dans un tel cas, les conduites 11 se déroulent à l'intérieur de l'élément 3 lors de la sortie de ce dernier et frottent contre le vérin 4 et contre les parois internes de l'élément 3.According to a characteristic of the invention, the flexible pipes 11 can extend on either side of the jack 4 without providing for particular guidance. In such a case, the pipes 11 take place inside the element 3 when it leaves the latter and rub against the jack 4 and against the internal walls of the element 3.

Pour éviter une détérioration par usure des conduites 11 pendant les opérations de sortie et de rentrée de l'élément 3, il est proposé selon une autre caractéristique de l'invention, et comme le montrent les figures 1 à 4 des dessins annexés, de monter lesdites conduites flexibles 11 dans un moyen de guidage flexible 15.To avoid deterioration by wear of the pipes 11 during the operations of removing and re-entering the element 3, it is proposed according to another characteristic of the invention, and as shown in Figures 1 to 4 of the accompanying drawings, to mount said flexible pipes 11 in a flexible guide means 15.

Un tel moyen de guidage flexible 15 peut être constitué sous forme d'une gaine flexible logeant une ou plusieurs conduites 11, de préférence deux conduites 11.Such a flexible guide means 15 can be constituted in the form of a flexible sheath housing one or more pipes 11, preferably two pipes 11.

Selon une autre caractéristique de l'invention, ce moyen de guidage flexible 15 sera constitué, comme représenté aux figures 2 à 4, par une gaine à maillons articulés, réalisée en matière synthétique ou en métal. Une telle gaine articulée permet un mouvement de déroulement et d'enroulement des conduites flexibles 11 pratiquement sans entrave, de sorte que l'encombrement de l'ensemble gaine 15 et conduites flexibles 11 est sensiblement identique à l'encombrement des conduites 11 seules.According to another characteristic of the invention, this flexible guide means 15 will be constituted, as shown in Figures 2 to 4, by a sheath with articulated links, made of synthetic material or metal. Such an articulated sheath allows an unwinding and winding movement of the flexible pipes 11 practically without hindrance, so that the size of the sheath 15 and flexible pipes 11 assembly is substantially identical to the size of the pipes 11 alone.

En outre, ce mode de réalisation assure les conduites 11 contre tout risque de détérioration par contact avec les faces internes de l'élément télescopique 3.In addition, this embodiment ensures the pipes 11 against any risk of deterioration by contact with the internal faces of the telescopic element 3.

Conformément à une autre variante de réalisation de l'invention, non représentée aux dessins annexés, le caisson formant l'élément télescopique 3 peut être subdivisé en trois compartiments longitudinaux, à savoir un compartiment central logeant le vérin 4 et deux compartiments latéraux de logement et de guidage des conduites hydrauliques 10 et éventuellement des moyens de guidage flexible 15.According to another alternative embodiment of the invention, not shown in the accompanying drawings, the box forming the telescopic element 3 can be subdivided into three longitudinal compartments, namely a central compartment housing the jack 4 and two lateral housing compartments and for guiding hydraulic lines 10 and possibly flexible guiding means 15.

Un tel mode de réalisation permet d'éviter tout risque de contact et/ou de coincement des conduites hydrauliques avec le vérin 4.Such an embodiment makes it possible to avoid any risk of contact and / or jamming of the hydraulic lines with the jack 4.

Il est également possible, selon une autre variante de réalisation, non représentée aux dessins annexés, de disposer les conduites 10 sous forme de conduites flexibles par enroulement en spirale autour du vérin 4.It is also possible, according to another alternative embodiment, not shown in the appended drawings, to arrange the pipes 10 in the form of flexible pipes by spiral winding around the jack 4.

Dans un tel cas, lors de la sortie de l'élément télescopique 3, le pas des spires de l'enroulement formé autour du vérin 4 augmente pour compenser l'allongement correspondant, ce pas diminuant lors de la rétraction.In such a case, when the telescopic element 3 leaves, the pitch of the turns of the winding formed around the jack 4 increases to compensate for the corresponding elongation, this pitch decreasing during retraction.

Ce mode de réalisation présente, en outre, l'avantage de ne nécessiter aucun moyen de guidage ou de protection particulier des conduites flexibles.This embodiment also has the advantage of not requiring any particular means of guiding or protecting the flexible pipes.

Selon une autre caractéristique de l'invention, le nez 5 de fixation d'un élément de manutention ou analogue est constitué par deux joues 5' insérées et fixées dans la partie avant de l'élément télescopique 3 et permettant l'ancrage du vérin 4. Ces joues 5' sont insérées dans l'élément 3 d'une longueur suffisante pour permettre une bonne répartition de l'effort dû à la charge.According to another characteristic of the invention, the nose 5 for fixing a handling element or the like consists of two cheeks 5 'inserted and fixed in the front part of the telescopic element 3 and allowing the anchoring of the jack 4. These cheeks 5' are inserted in the element 3 of sufficient length to allow good distribution of the effort due to the load.

Les platines 6 de fixation des raccords hydrauliques 7 sont montées sur les joues 5' du nez 5, de manière amovible, par exemple vissage ou boulonnage.The plates 6 for fixing the hydraulic connectors 7 are mounted on the cheeks 5 'of the nose 5, in a removable manner, for example screwing or bolting.

Une telle fixation est destinée à permettre un démontage aisé des platines et un accès à la fixation des raccords, notamment en vue d'un démontage total de l'élément télescopique 3.Such a fixing is intended to allow easy dismantling of the plates and access to the fixing of the fittings, in particular with a view to total disassembly of the telescopic element 3.

Grâce à l'invention, il est possible de réaliser une flèche télescopique de grue, en particulier de grue repliable, dans laquelle l'élément télescopique loge entièrement les conduites hydrauliques d'asservissement du dispositif de manutention monté sur le nez, de sorte que ladite grue ne présente plus aucune conduite hydraulique à l'extérieur de ses bras, seules les conduites de raccordement au niveau des articulations restant visibles. Il en résulte que les grues ainsi équipées présentent une sécurité très nettement accrue contre les risques de détérioration des circuits hydrauliques.Thanks to the invention, it is possible to produce a telescopic boom for a crane, in particular a foldable crane, in which the telescopic element entirely houses the hydraulic control lines of the handling device mounted on the nose, so that said crane no longer has any hydraulic lines outside its arms, only the connecting lines at the joints remaining visible. As a result, the cranes thus equipped have a very markedly increased safety against the risks of deterioration of the hydraulic circuits.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
