The additional arm and counterweight balancer are connected by a pulley system (10,10') at the front end of the main arm and a second pulley system (28,28') at the rear of the main arm. The pulley systems are connected by a cable which is controlled by a hydraulic cylinder.

Description

La présente invention concerne les grues à flèche à bras articulés ou télescopiques pour le levage ou la manutention de charges au grappin, à la benne preneuse, au treuil-crochet ou au crochet. Elle concerne en particulier un dispositif qui assure un équilibrage automatique de la flèche de telles grues en fonction de la variation de la portée de la flèche.The present invention relates to jib cranes with articulated or telescopic arms for lifting or handling of grapple loads, grab, winch-hook or hook. It concerns in particular a device which ensures automatic balancing of the deflection of such cranes according to the variation of the reach of the arrow.

On connaít des grues de ce genre dans lesquelles la flèche est généralement articulée sur la tourelle et est équipée d'un contrepoids « à géométrie variable » monté sur un bras de levier qui se déploie, à l'arrière de la flèche, en fonction de la position du bras auxiliaire de la flèche. Dans ce cas le contrepoids ne sert qu'à réduire le moment de renversement d'une valeur fixe, et sans compensation en fonction de la portée de la flèche.We know of cranes of this kind in which the boom is usually hinged on the turret and is equipped with a “variable geometry” counterweight mounted on a lever arm which is deployed at the rear of the boom, depending on the position of the boom's auxiliary arm. In this case the counterweight only serves to reduce the moment reversal of a fixed value, and without compensation in depending on the reach of the arrow.

Pour assurer l'automaticité de l'équilibrage, le document EP-A- 0 033 060 propose de relier mécaniquement le bras auxiliaire et le contrepoids par une bielle rigide déterminant un parallélogramme déformable. Pour le même objet il a été aussi proposé, par le document EP-A- 0 110 786, un système de vérins hydrauliques reliés entre eux et actionnant simultanément le bras auxiliaire et le contrepoids.To ensure automatic balancing, the document EP-A- 0 033 060 proposes to mechanically connect the auxiliary arm and counterweight by a rigid rod determining a deformable parallelogram. For the same object it was also proposed, by document EP-A- 0 110 786, a system of hydraulic cylinders linked together and simultaneously operating the auxiliary arm and the counterweight.

Les systèmes mentionnés ci-dessus d'équilibrage des éléments de la flèche se sont montrés efficaces mais, comme ils comportent des bras de levier variables, ils présentent l'inconvénient que le couple nécessaire à l'équilibrage des éléments de la flèche n'est pas constant, mais diminue au fur et à mesure de l'augmentation de la portée de la flèche, d'où une augmentation considérable de la puissance nécessaire au levage de la charge. Ces dispositifs connus présentent aussi l'inconvénient que, du fait même de leur conception, la cinématique des mouvements de la flèche se trouve limitée. Enfin, le poids de la bielle de liaison (dans le dispositif du document EP-A-0 033 060) comme le poids du vérin du bras auxiliaire (dans le dispositif du document EP-A- 0 110 786) pénalise le système.The above mentioned systems for balancing elements of the boom have been shown to be effective but, as they have variable leverage, they have the disadvantage that the torque required to balance the elements of the arrow is not constant, but decreases with as the scope of the arrow, hence a considerable increase in power necessary for lifting the load. These known devices also have the disadvantage that, by the very fact of their design, the kinematics of the boom movements are found limited. Finally, the weight of the connecting rod (in the device of document EP-A-0 033 060) like the weight of the auxiliary arm cylinder (in the device of the document EP-A- 0 110 786) penalizes the system.

Par le document US N° 4 252 162 on connaít un bras de chargement destiné à transférer des produits, tels que des produits pétroliers, entre deux citernes ou réservoirs. Ce bras de chargement comprend un tube interne porté par un support avec vérin de commande faisant varier la position du tube interne par rapport au support, un tube externe articulé à une extrémité du tube interne et une poutre d'équilibrage articulée à l'autre extrémité du tube interne. Une liaison par poulies et câbles est réalisée entre le tube externe et la poutre d'équilibrage, en liant ainsi la position de ces deux éléments. Un vérin de commande du tube externe est porté par le tube interne et la tige de ce vérin est attelée à la poutre d'équilibrage pour commander la position du tube externe.By US document No. 4,252,162 we know an arm loading intended to transfer products, such as petroleum products, between two tanks or reservoirs. This loading arm includes an inner tube carried by a support with control cylinder varying position of the inner tube relative to the support, an outer tube articulated at one end of the inner tube and a beam balancing joint at the other end of the tube internal. A connection by pulleys and cables is carried out between the outer tube and the balancing beam, by tying thus the position of these two elements. A cylinder of control of the outer tube is carried by the inner tube and the rod of this cylinder is coupled to the balancing beam to control the position of the outer tube.

Le dispositif du document US N° 4 252 162 n'a donc pas du tout le même objet que le dispositif selon l'invention, puisqu'il s'agit d'un bras de chargement de liquide, c'est-à-dire d'une tuyauterie articulée destinée au transfert de liquide entre deux réservoirs, et qui n'est donc pas soumise à de fortes charges, et pas à une flèche de grue dont le rôle est au contraire de soulever et de déplacer des charges importantes.The device of US document No. 4,252,162 has therefore not at all the same object as the device according to the invention, since it is a loading arm of liquid, i.e. articulated piping intended the transfer of liquid between two tanks, and which is not therefore not subject to heavy loads, and not to an arrow crane whose role is instead to lift and move large loads.

En outre, selon le document US N° 4 252 162, la tige du vérin de commande du tube externe est attelée à la poutre d'équilibrage de sorte que, Lors de la commande de position du tube externe, on a donc une variation du bras de levier ce qui empêche d'avoir un couple constant en obligeant à utiliser un vérin de commande de plus forte puissance.Furthermore, according to US document No. 4,252,162, the rod of the control cylinder of the outer tube is coupled to the balancing beam so that, when ordering from position of the outer tube, so we have a variation of the arm lever which prevents having a constant torque in requiring the use of a stronger control cylinder power.

La présente invention a pour objet d'éviter les inconvénients mentionnés ci-dessus des dispositifs connus et elle propose d'équiper la flèche de grue d'un dispositif d'équilibrage qui, tout en présentant une grande efficacité et un poids réduit, supprime la présence de bras de levier variables et les inconvénients qu'ils entraínent au niveau de la puissance nécessaire au levage du bras auxiliaire, et améliore la cinématique des mouvements de la flèche.The object of the present invention is to avoid above mentioned disadvantages of known devices and she proposes to equip the crane boom with a device balancing which, while having great efficiency and reduced weight, eliminates the presence of lever arms variables and the drawbacks they entail at the level the power required to lift the auxiliary arm, and improves the kinematics of the boom movements.

A cet effet la flèche de grue à portée variable selon l'invention est du type comprenant un bras principal monté pivotant sur une tourelle de support, un bras auxiliaire prolongeant le bras principal en étant articulé à l'extrémité avant de celui-ci, un contrepoids fixé sur un balancier articulé fixé à l'extrémité arrière du bras principal, et des moyens de liaison entre ledit bras auxiliaire et ledit balancier du contrepoids pour réaliser à tout moment un équilibrage total ou partiel de la flèche. Elle se caractérise en ce que les dits moyens de liaison comprennent un premier système de poulie monté en rotation à l'extrémité avant du bras principal et solidaire en rotation de l'extrémité adjacente du bras auxiliaire, un second système de poulie monté en rotation à l'extrémité arrière du bras principal et solidaire en rotation de l'extrémité adjacente du balancier, un lien souple reliant un point du premier système de poulie à un point du second système de poulie, et un moyen de commande du déplacement du lien souple assurant le pivotement simultané du bras auxiliaire et du balancier pour modifier la portée de la flèche en assurant l'équilibrage de celle-ci, ledit moyen de commande étant porté par le bras principal et étant attelé au dit lien souple pour obtenir un bras de levier constant en maintenant constant le couple nécessaire à l'équilibrage des éléments de la flèche.For this purpose the crane boom with variable reach according to the invention is of the type comprising a main arm mounted pivoting on a support turret, an auxiliary arm extending the main arm by being articulated to the front end of it, a counterweight attached to a articulated pendulum attached to the rear end of the arm main, and connecting means between said arm auxiliary and said counterweight pendulum to realize at any time a total or partial balancing of the boom. It is characterized in that the said means of connection include a first pulley system rotatably mounted at the front end of the main arm and secured in rotation of the adjacent end of the auxiliary arm, a second pulley system rotatably mounted at the end rear of the main arm and integral in rotation with the adjacent end of the pendulum, a flexible link connecting a point on the first pulley system at a point on the second pulley system, and displacement control means flexible link ensuring simultaneous pivoting of the arm auxiliary and pendulum to modify the scope of the arrow ensuring the balance thereof, said means being carried by the main arm and being harnessed to said flexible link to obtain a lever arm constant by keeping constant the torque necessary to balancing of the boom elements.

Avantageusement, l'extrémité avant du bras principal se prolonge par deux bras parallèles écartés entre lesquels est placée l'extrémité arrière du bras auxiliaire, ladite extrémité arrière étant solidaire sur chacune de ses faces latérales opposées d'une poulie à gorge, l'ensemble formé par l'extrémité arrière du bras auxiliaire et par les poulies pivotant autour d'un axe d'articulation qui tourillonne dans des ouvertures en regard des dits bras parallèles.Advantageously, the front end of the main arm is extended by two spaced parallel arms between which is placed the rear end of the auxiliary arm, said rear end being integral with each of its faces opposite sides of a grooved pulley, the assembly formed by the rear end of the auxiliary arm and by the pulleys pivoting around a hinge pin which swirls in openings opposite said arms parallel.

De façon similaire le balancier solidaire du contrepoids présente vers l'avant deux bras parallèles ménageant entre eux un espace pour l'extrémité arrière du bras principal, lesdits bras étant chacun solidaire d'une poulie à gorge et l'ensemble formé par les bras et les poulies à gorge pivotent autour d'un axe d'articulation qui tourillonne dans une ouverture transversale de l'extrémité arrière du bras principal.Similarly, the balance attached to the counterweight has two parallel arms forward providing space between them for the rear end of the main arm, said arms each being integral with a grooved pulley and the assembly formed by the arms and grooved pulleys pivot about an articulation axis which swivels in a transverse opening of the end back of the main arm.

De chaque côté du bras principal de la flèche , un câble souple relie la poulie avant à la poulie arrière, ce câble étant fixé à un point de la poulie avant et à un point de la poulie arrière. Ainsi le déplacement dans une direction des deux câbles souples entraíne la rotation des poulies dans un même sens en provoquant, avec un bras de levier constant, le soulèvement du bras auxiliaire et le basculement simultané du contrepoids, alors que le déplacement de ces câbles souples dans l'autre direction entraíne la rotation des quatre poulies en sens inverse en provoquant, également avec un bras de levier constant, le basculement du bras auxiliaire et le soulèvement simultané du contrepoids.On each side of the main boom arm, a flexible cable connects the front pulley to the rear pulley, this cable being attached to a point on the front pulley and to a point of the rear pulley. So moving in a direction of the two flexible cables causes the rotation of pulleys in the same direction by provoking, with an arm of constant lever, the lifting of the auxiliary arm and the simultaneous tilting of the counterweight, while the displacement of these flexible cables in the other direction causes the rotation of the four pulleys in opposite directions causing, also with a constant lever arm, the tilting of the auxiliary arm and simultaneous lifting counterweight.

Avantageusement, la commande du déplacement des câbles souples est assurée par un vérin hydraulique unique, dont le cylindre est articulé sur le bras principal de la flèche et dont la tige est solidaire d'un organe de liaison transversal fixé à chaque extrémité en un point de chacun des deux câbles souples. Le vérin est à double effet et est associé à un distributeur de fluide hydraulique à trois positions, comprenant une position centrale isolant les deux chambres du vérin de la pompe hydraulique et du réservoir de fluide, et deux positions latérales reliant l'une ou l'autre des chambres du vérin à la pompe hydraulique et la chambre restante au réservoir, en commandant sélectivement la sortie ou la rétraction de la tige (15) du vérin.Advantageously, the control of the movement of the flexible cables is ensured by a single hydraulic cylinder, whose cylinder is articulated on the main arm of the arrow and whose rod is integral with a connecting member transverse fixed at each end at a point of each two flexible cables. The cylinder is double acting and is associated with a three-way hydraulic fluid distributor positions, including a central position isolating the two chambers for the hydraulic pump cylinder and fluid reservoir, and two lateral positions connecting either of the chambers of the cylinder to the pump hydraulic and the remaining chamber to the tank, in selectively controlling the exit or retraction of the cylinder rod (15).

Pour bien faire comprendre l'invention on en décrira ci-après, à titre d'exemple sans caractère limitatif, une forme d'exécution préférée en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue de côté d'une flèche de grue à bras articulés, équipée d'un dispositif d'équilibrage automatique selon l'invention ; et
  • la figure 2 est une vue de dessus de la flèche de grue de la figure 1.
    • To clearly understand the invention, a preferred embodiment will be described below, by way of example, with reference to the appended schematic drawing in which:
  • Figure 1 is a side view of a jib crane with articulated arms, equipped with an automatic balancing device according to the invention; and
  • Figure 2 is a top view of the crane boom of Figure 1.

    • En référence au dessin, on a représenté en 1 le socle de la grue, en 2 la tourelle pivotante surmontant ce socle et en 3 le bras principal de la flèche articulé, vers son extrémité arrière, au sommet de la tourelle 2 autour d'un axe horizontal 4 pour pouvoir pivoter dans un plan vertical sous la commande d'un vérin hydraulique 5.With reference to the drawing, the base has been represented in 1 of the crane, in 2 the pivoting turret surmounting this base and in 3 the main arm of the articulated boom, towards its rear end, at the top of turret 2 around a horizontal axis 4 to be able to pivot in a vertical plane under the control of a hydraulic cylinder 5.

    A l'extrémité avant du bras principal 3 est articulé, autour d'un axe horizontal 6, un bras auxiliaire 7 dont l'extrémité avant porte un moyen de préhension constitué, dans l'exemple représenté, par une benne preneuse 8.At the front end of the main arm 3 is articulated, around an horizontal axis 6, an auxiliary arm 7 of which the front end carries a gripping means constituted, in the example shown, by a clamshell bucket 8.

    A cet effet, comme on le voit à la figure 2, l'extrémité avant du bras principal 3 présente deux branches axiales parallèles écartées 3', 3" percées de trous en regard dans lesquels tourillonne l'axe d'articulation horizontal transversal 6. Les faces latérales opposées de l'extrémité arrière du bras auxiliaire 7 sont solidaires chacune d'une poulie à gorge 10', 10'', et l'ensemble formé par le bras auxiliaire 7 et les poulies 10', 10" est traversé par l'axe 6.For this purpose, as seen in Figure 2, the front end of the main arm 3 has two parallel axial branches spaced 3 ', 3 "pierced with facing holes in which the axis journals horizontal transverse joint 6. The faces opposite sides of the rear end of the arm auxiliary 7 are each secured to a grooved pulley 10 ', 10' ', and the assembly formed by the auxiliary arm 7 and the pulleys 10 ', 10 "is crossed by the axis 6.

    A l'extrémité arrière du bras principal 3 est articulé, autour d'un axe horizontal transversal 12, un balancier à bras parallèles 13', 13'', disposés de part et d'autre du bras principal 3 et portant un contrepoids 14.At the rear end of the main arm 3 is articulated around a horizontal transverse axis 12, a pendulum with parallel arms 13 ', 13' ', arranged on either side on the other side of the main arm 3 and carrying a counterweight 14.

    Chaque bras 13', 13" du balancier a sa face intérieure solidaire d'une poulie à gorge 28', 28'', et l'axe d'articulation 12, tourillonne dans des trous en regard du bras principal et de l'ensemble formé par chaque bras de balancier 13', 13" et la poulie à gorge associée 28', 28"Each arm 13 ', 13 "of the pendulum has its face interior secured to a 28 ', 28' 'grooved pulley, and the hinge pin 12, pivots in holes in look of the main arm and the assembly formed by each 13 ', 13 "balance arm and associated grooved pulley 28 ', 28 "

    Les poulies à gorge 10', 28' d'une part et 10", 28" d'autre part sont dans le prolongement l'une de l'autre et sur chacun de ces couples de poulies 10'-28', 10''-28'' est disposé un câble souple sans fin, respectivement 27',27''. Chaque câble souple 27',27" comporte une fixation en 9 sur la poulie avant respective 10',10" et en 30 sur la poulie arrière respective 28',28'', de sorte que les poulies 10',28' et 10",28" sont reliées entre elles respectivement.Grooved pulleys 10 ', 28' on the one hand and 10 ", 28" on the other hand are an extension of each other and on each of these pairs of pulleys 10'-28 ', 10' '- 28' 'is arranged an endless flexible cable, respectively 27 ', 27' '.

    Un vérin hydraulique 16 à double effet est fixé, au moyen d'une chape d'articulation 17, au-dessus du bras principal 3 et sa tige 15 est fixée, par l'intermédiaire d'une barre transversale de liaison 32, aux câbles souples 27', 27" en des points 31',31'' respectivement.A double-acting hydraulic cylinder 16 is attached to the by means of a hinge yoke 17, above the arm main 3 and its rod 15 is fixed, via a connecting crossbar 32, with flexible cables 27 ', 27 "at points 31', 31 '' respectively.

    • une position correspondant à la partie de gauche du schéma du distributeur20 de la figure 1, dans laquelle le conduit 23 menant à la chambre 24 du vérin 16 est relié à la pompe 19 et le conduit 25 menant à la chambre 26 du vérin 16 est relié au réservoir 18,
    • une position correspondant à la partie de droite du schéma du distributeur 20 de la figure 1, dans laquelle, à l'inverse, la chambre 24 du vérin 16 est reliée au réservoir 18 et la chambre 26 du vérin 16 est reliée à la pompe d'alimentation 19.
    By actuation of a control member not shown, the distributor 20 can take the following 3 different positions:
    • a central position shown in the drawing in which the conduits 23 and 25 leading to the jack 16 are isolated from the fluid supply and from the reservoir,
    • a position corresponding to the left-hand part of the diagram of the distributor 20 of FIG. 1, in which the conduit 23 leading to the chamber 24 of the jack 16 is connected to the pump 19 and the conduit 25 leading to the chamber 26 of the jack 16 is connected to reservoir 18,
    • a position corresponding to the right-hand part of the diagram of the distributor 20 of FIG. 1, in which, conversely, the chamber 24 of the jack 16 is connected to the reservoir 18 and the chamber 26 of the jack 16 is connected to the pump d food 19.

    On décrira maintenant le fonctionnement du dispositif selon l'invention. La grue étant dans la position équilibrée de la figure 1, si l'opérateur désire allonger la portée de la flèche, il place alors le distributeur 20 dans la position correspondant à la partie de gauche de son schéma de la figure 1, c'est-à-dire qu'il alimente la chambre 24 du vérin 16 en fluide sous pression en provoquant la sortie de la tige 15 qui, fixée aux câbles 27',27'' en 31',31'', exerce une traction sur ces câbles pour les déplacer de gauche vers la droite en regardant la figure 1. Les câbles 27',27" étant fixés aux poulies 10',10" en 9 et aux poulies 28',28" en 30',30", leur déplacement entraíne la rotation dans le sens horaire des poulies 10',10'' et 28',28'', ce qui produit simultanément le soulèvement du bras auxiliaire 7 et le basculement du contrepoids 14. Comme la valeur du contrepoids 14 est calculée en fonction du poids propre des éléments de la flèche et de la benne preneuse 8, et en fonction du diamètre des poulies 10,10' et 28,28', la flèche se trouve donc équilibrée en permanence, en totalité ou en partie, sur l'ensemble formé par le socle 1 et la tourelle 2. Lorsque la position d'allongement désirée de la flèche est atteinte, l'opérateur ramène le distributeur 20 dans sa position centrale, en immobilisant la tige de vérin 15, et les opérations de levage et de descente de la charge sont alors assurées par le vérin 5.We will now describe the operation of the device according to the invention. The crane being in position balanced of figure 1, if the operator wishes to lengthen the reach of the arrow, it then places the distributor 20 in the position corresponding to the left part of his diagram of Figure 1, that is to say that it feeds the chamber 24 of cylinder 16 in pressurized fluid in causing the exit of the rod 15 which, fixed to the cables 27 ', 27' 'in 31', 31 '', pulls on these cables to move them from left to right looking at the figure 1. The cables 27 ', 27 "being fixed to the pulleys 10 ', 10 "in 9 and with pulleys 28', 28" in 30 ', 30 ", their displacement causes the clockwise rotation of pulleys 10 ', 10' 'and 28', 28 '', which produces simultaneously lifting the auxiliary arm 7 and tilting the counterweight 14. Since the value of counterweight 14 is calculated according to the self-weight of the elements of the boom and clamshell bucket 8, and depending on the pulley diameter 10.10 'and 28.28', the arrow is therefore permanently balanced, in whole or in part, on the assembly formed by the base 1 and the turret 2. When the desired boom position is reached, the operator brings the dispenser 20 back into its central position, immobilizing the cylinder rod 15, and the lifting and lowering operations are then ensured by the jack 5.

    Si l'opérateur décide, inversement, de raccourcir la portée de la flèche, il place le distributeur 20 dans la position de droite de son schéma de figure 1, c'est-à-dire qu'il alimente la chambre annulaire du vérin 16 en fluide sous pression. Par son mouvement de rétraction, la tige du vérin 15 déplace vers la gauche de la figure 1 les câbles 27',27" qui, par leur points de liaison 9 et 30',30", entraínent les poulies 10',10" et 28',28" en rotation dans le sens anti-horaire. Il s'ensuit un basculement du bras auxiliaire 7 et un relèvement simultané du contrepoids 14 qui assurent l'équilibrage automatique de la flèche.If the operator decides, conversely, to shorten the reach of the arrow, it places the distributor 20 in the right position of its diagram of figure 1, that is to say that it supplies the annular chamber of the jack 16 with fluid under pressure. By its retraction movement, the rod of the cylinder 15 moves the cables to the left of figure 1 27 ', 27 "which, by their connection points 9 and 30', 30", drive the pulleys 10 ', 10 "and 28', 28" in rotation counterclockwise. It follows a tilting of the auxiliary arm 7 and a simultaneous lifting of the counterweight 14 which provide automatic balancing of the boom.
