Description

La présente invention concerne un dispositif permettant de manutentionner, enclencher entre eux, guider, foncer, mettre en fiche des profilés métalliques ou palplanches.The present invention relates to a device for handling, interlocking between them, guiding, sinking, filing metal profiles or sheet piles.

Toutes ces opérations se réalisent actuellement à l'aide de grues à flèche treillis qui portent au crochet un vibrofonceur ou un trépideur.All these operations are currently carried out using lattice boom cranes which carry a vibratory hammer or a fastener on the hook.

Elles nécessitent pour chaque palplanche ou profilé les manipulations suivantes : accrochage de la palplanche au sol, levage, enclenchement, décrochage, descente du crochet, arrimage du matériel de battage, levage, mise en place sur le profilé, positionnement de l'ensemble, battage, plusieurs arrêts, plusieurs positionnements.They require the following manipulations for each sheet pile or section: hooking the sheet pile to the ground, lifting, engaging, unhooking, lowering the hook, lashing of the threshing material, lifting, positioning on the section, positioning of the assembly, threshing , several stops, several positioning.

Ces opérations sont liées à l'emploi de grues à câble qui ne permettent pas de guidage ni de manutentions précises ; de plus, seuls les mouvements d'oscillation verticaux ou les trépidations qui viennent compléter le poids de l'engin de battage permettent l'enfoncement du profilé.These operations are linked to the use of cable cranes which do not allow precise guidance or handling; moreover, only the vertical oscillating movements or the vibrations which complete the weight of the threshing machine allow the profile to be pushed in.

Ces opérations multiples et aléatoires limitent fortement les rendements. De plus, les opérations de battage nécessaitent une deuxième source d'énergie et sont soumises aux conditions météorologiques (pluie, vent, gel).These multiple and random operations severely limit yields. In addition, the threshing operations required a second source of energy and were subject to weather conditions (rain, wind, frost).

L'invention a pour objet de remédier à ces inconvénients.The object of the invention is to remedy these drawbacks.

Conformément à l'invention, on propose en effet un dispositif permettant de manutentionner, enclencher entre eux, guider, foncer, mettre en fiche des profilés métalliques ou palplanches, caractérisé en ce qu'il est disposé à l'extrémité d'un bras de pelle hydraulique par le biais d'une platine de montage montée sur ledit bras de pelle hydraulique, ladite platine étant solidaire d'un bâti sur lequel est fixée une pince à rotation de 360° qui appréhende et maintient les profilés par leurs ailes, à un endroit quelconque de leurs chants latéraux.In accordance with the invention, a device is proposed which makes it possible to handle, engage them, guide, sink, put in sheet metal or sheet pile sections, characterized in that it is arranged at the end of an arm of hydraulic shovel by means of a mounting plate mounted on said hydraulic shovel arm, said plate being secured to a frame on which is fixed a 360 ° rotation clamp which apprehends and maintains the profiles by their wings, at a any place of their side chants.

Avantageusement, on disposera sous le bâti un dispositif de sécurité qui, dans sa position avant, interdit un glissement intempestif des profilés ou palplanches.Advantageously, there will be placed under the frame a safety device which, in its front position, prevents inadvertent sliding of the sections or sheet piles.

Selon une caractéristique essentielle, est montée sur le bâti une pièce oscillante, au sommet de laquelle s'articule une flèche télescopique rabattable, qui guide le déplacement d'un chariot coulissant, support de la platine de montage du marteau de battage.According to an essential characteristic, is mounted on the frame an oscillating part, at the top of which is articulated a telescopic folding arrow, which guides the movement of a sliding carriage, support of the mounting plate of the threshing hammer.

Le dispositif de l'invention fonctionne en utilisant comme source d'énergie celle de la pelle qui le porte et comporte donc une platine qui permet son montage sur le bras de la pelle hydraulique, qui lui confère les mêmes possibilités de mouvements qu'un godet.The device of the invention operates by using as an energy source that of the shovel which carries it and therefore comprises a plate which allows its mounting on the arm of the hydraulic shovel, which gives it the same possibilities of movement as a bucket. .

Sur ce dispositif, par l'intermédiaire du bâti, est fixée une pince qui se place à l'horizontale, face avant dessous, sur une pile de profilés, en une quelconque partie de la longueur de ceux-ci. Les mâchoires de la pince sont alors actionnées. Elles pressent, par ce fait, le profilé à soulever, en agissant sur ses ailes, contre une matrice, qui leur interdit tout déplacement. Le profilé est alors soulevé à l'horizontale devant la pelle hydraulique. Une rotation de quatre vingt dix degrés du système d'orientation supportant la pince, permet de le placer à la verticale. Le battage peut alors débuter, sauf dans le cas de palplanches dont le pied est posé au sol, tout en desserrant légèrement la pince, ce qui provoque le glissement du dispositif jusqu'au bas de celles-ci. Les mâchoires sont resserrées sur les serrures. Le dispositif de sécurité placé sous la pince, poussé par son système de manoeuvre, coulisse vers l'avant et se place sous les palplanches, pour éviter un glissement intempestif. Celles-ci, tenues à la verticale par leur partie basse, sont alors élevées au niveau du haut du rideau déjà en place et leur serrure enclenchée dans la serrure de a palplanche précédemment mise en fiche.On this device, by means of the frame, is fixed a clamp which is placed horizontally, front face below, on a stack of profiles, in any part of the length thereof. The jaws of the pliers are then actuated. By this fact, they press the profile to be lifted, by acting on its wings, against a die, which prevents them from moving. The profile is then raised horizontally in front of the hydraulic shovel. A rotation of ninety degrees of the orientation system supporting the clamp, allows it to be placed vertically. The threshing can then begin, except in the case of sheet piles whose foot is placed on the ground, while slightly loosening the clamp, which causes the device to slide to the bottom thereof. The jaws are tightened on the locks. The safety device placed under the clamp, pushed by its operating system, slides forward and is placed under the sheet piles, to avoid inadvertent sliding. These, held vertically by their lower part, are then raised to the level of the top of the curtain already in place and their lock engaged in the sheet pile lock previously plugged.

Au début de l'enclenchement, le mouvement de descente est accompagné par la pince jusqu'à ce que le support de mâchoires entre en contact avec le haut du rideau. Le serrage cesse à ce moment et la palplanche glisse jusqu'au sol sous l'effet de son propre poids.At the start of engagement, the downward movement is accompanied by the clamp until the jaw support comes into contact with the top of the curtain. Tightening ceases at this time and the sheet pile slides to the ground under the effect of its own weight.

La pince, maintenue dans cette position, règle la verticalité et l'alignement, empêchant toute déviation en début de battage.The clamp, held in this position, adjusts the verticality and alignment, preventing any deviation at the start of threshing.

Ce dernier commence par l'amenée en position verticale, par son dispositif de relevage, d'une flèche télescopique, articulée au sommet d'un caisson oscillant, dont l'axe est aligné avec l'axe de rotation de la pince. Le repliement ou le déploiement de la flèche règle alors la hauteur du marteau et le place sur le profilé à battre, en y maintenant une pression pendant la frappe. Un dispositif complémentaire commande le coulissement d'un chariot qui porte la pièce d'adaptation du marteau et prolonge cette action jusqu'à ce que le coulisseau atteigne le pied de flèche, tout en maintenant une pression verticale sur le profilé. Lorsque l'enclume du marteau atteint le niveau de la première matrice, la pince est basculée de 90°, en autorisant la poursuite du battage jusqu'à ce que les têtes des palplanches atteignent le niveau désiré.The latter begins by bringing it into a vertical position, by its lifting device, of a telescopic boom, articulated at the top of an oscillating box, the axis of which is aligned with the axis of rotation of the clamp. The folding or unfolding of the boom then adjusts the height of the hammer and places it on the profile to be beaten, maintaining pressure during striking. A complementary device controls the sliding of a carriage which carries the adaptation piece of the hammer and extends this action until the slide reaches the foot of arrow, while maintaining vertical pressure on the profile. When the hammer's anvil reaches the level of the first die, the clamp is tilted by 90 °, allowing the pile to continue driving until the sheet pile heads reach the desired level.

Le dispositif représenté sur les figures 1 à 5 dans son ensemble, comporte une platine (1) soudée sur un bâti (2). Celui-ci est constitué de deux tôles fortes (3) espacées de 30cm environ et solidarisées entre elles par trois entretoises (4) de même nature. Deux verticales sont placées aux extrémités latérales ; l'autre horizontale est placée à la base des précédentes.The device shown in Figures 1 to 5 as a whole, comprises a plate (1) welded to a frame (2). This consists of two strong sheets (3) spaced about 30cm apart and joined together by three spacers (4) of the same kind. Two verticals are placed at the lateral ends; the other horizontal is placed at the base of the previous ones.

Le bâti, vu de derrière sur la figure 2, présente dans sa partie supérieure, la forme d'un demi-cercle et dans sa partie inférieure, celle d'un rectangle d'environ deux mètres de long.The frame, seen from behind in Figure 2, has in its upper part, the shape of a semicircle and in its lower part, that of a rectangle about two meters long.

La pièce arrière du bâti est semblable à la précédente, tronquée de sa partie en demi-cercle.The rear part of the frame is similar to the previous one, truncated from its part in a semicircle.

La face avant circonscrit une couronne d'orientation (5), entrainée en rotation par le pignon (6) d'un moteur hydraulique (7), placé dans l'espace libre aménagé entre les deux faces du bâti.The front face circumscribes an orientation ring (5), driven in rotation by the pinion (6) of a hydraulic motor (7), placed in the free space provided between the two faces of the frame.

La partie fixe de la couronne est boulonnée au bâti. La partie mobile, à rotation totale de 360°, entraîne dans son mouvement une tôle (8) qui supporte la pince de préhension des palplanches.The fixed part of the crown is bolted to the frame. The movable part, with a total rotation of 360 °, drives in its movement a sheet (8) which supports the gripper for gripping the sheet piles.

Celle-ci, selon les figures 5 à 7 se compose de deux traverses (9) réalisées en tube carré, sur lesquelles coulissent quatre supports de mâchoires (10) opposés deux à deux sur chaque traverse.This, according to Figures 5 to 7 consists of two crosspieces (9) made of square tube, on which slide four jaw supports (10) opposite two by two on each crosspiece.

Les supports peuvent être immobilisés sur les traverses, à l'aide de broches (11), introduites dans les alésages qui les transpercent de part en part.The supports can be immobilized on the sleepers, using pins (11), introduced into the bores which pierce them right through.

Chaque support est constitué d'un tube carré coulissant autour de celui de la traverse, sur les faces latérales duquel sont soudées deux tôles de forme trapézoidale entretoisées. Entre ces tôles est logée une mâchoire (12), ayant la forme d'une portion de cercle qui se meut en rotation autour d'un axe (13), traversant celle-ci et les deux tôles latérales du support.Each support consists of a square tube sliding around that of the cross member, on the side faces of which are welded two trapezoidal sheets braced. Between these sheets is housed a jaw (12), having the shape of a portion of a circle which rotates about an axis (13), passing through it and the two lateral sheets of the support.

Le mouvement de rotation de la mâchoire est commandé par un petit vérin télescopique (14) dont la tête est articulée sur la partie inférieure de la mâchoire et le bas du corps sur une longrine en profil H (15), soudée sur l'axe de symétrie longitudinal de la pince. L'autre extrémité de la mâchoire est en saillie par rapport au rayon de la portion de cercle et forme un mors dont la face de contact avec les serrures des palplanches est striée.The jaw rotation movement is controlled by a small telescopic cylinder (14) whose head is articulated on the part lower jaw and lower body on a sill in H profile (15), welded to the longitudinal axis of symmetry of the clamp. The other end of the jaw protrudes from the radius of the circle portion and forms a jaw whose contact face with the sheet pile locks is striated.

Entre les supports de mâchoires pris deux à deux, est emboîtée dans trois coulisseaux (16), une traverse d'une vingtaine de centimètres de largeur, présentant la forme d'une matrice de palplanche.Between the jaw supports taken two by two, is fitted into three slides (16), a crosspiece of about twenty centimeters in width, having the shape of a sheet pile matrix.

Le profil de celle-ci inscrit dans sa partie creuse, la face externe de la palplanche du plus gros module, tandis que sa partie convexe s'inscrit dans la face interne de la palplanche du plus petit module de la série à mettre en oeuvre, tel que représenté sur les figures 8 à 11.The profile of this inscribed in its hollow part, the external face of the sheet pile of the largest module, while its convex part is inscribed in the internal face of the sheet pile of the smallest module of the series to be used, as shown in Figures 8 to 11.

Sur les bords et au milieu de la matrice, dans le cas de paires de palplanches, sont ménagés des plats (17) à l'emplacement des serrures.On the edges and in the middle of the matrix, in the case of pairs of sheet piles, are provided plates (17) at the location of the locks.

Ces plats tiennent le rôle de mâchoire dormante de la pince.These dishes play the role of the gripper's sleeping jaw.

Deux des coulisseaux précédemment cités, sont aménagés sur le côté interne des supports des mâchoires mobiles, le troisième étant le profilé en H déjà utilisé comme base d'appui des vérins des mâchoires.Two of the above-mentioned slides are arranged on the internal side of the supports of the movable jaws, the third being the H-shaped section already used as the support base for the jaws jacks.

Les mâchoires peuvent être immobilisées en rotation par la mise en place d'une deuxième broche dans un autre perçage (18), ce qui, après enlèvement des matrices, permet de régler l'écartement des supports, à l'aide des vérins de serrage.The jaws can be immobilized in rotation by the installation of a second spindle in another bore (18), which, after removal of the dies, makes it possible to adjust the spacing of the supports, using the clamping jacks .

Une variante matérialisée par la figure 7, représente la pince équipée de mâchoires allongées qui permettent de saisir et de déplacer à l'horizontale une pile de palplanches lors d'un déchargement ou d'une distribution sur chantier.A variant shown in Figure 7 shows the clamp equipped with elongated jaws which allow to grip and move horizontally a pile of sheet piles during unloading or distribution on site.

Dans l'espace aménagé entre les deux faces du bâti, un caisson oscillant (19), représenté par les figures 12 à 14, est mobile autour d'un axe (20), dont le centre est aligné avec celui de la couronne d'orientation, ce qui lui permet une inclinaison de 15° environ de part et d'autre de son axe vertical, sous l'effet d'un vérin (21), articulé sous sa face inférieure d'une part, sur une entretoise verticale du bâti, d'autre part.In the space arranged between the two faces of the frame, an oscillating box (19), represented by FIGS. 12 to 14, is movable around an axis (20), the center of which is aligned with that of the crown orientation, which allows it to tilt approximately 15 ° on either side of its vertical axis, under the effect of a jack (21), articulated under its underside on the one hand, on a vertical spacer of the built, on the other hand.

Ce caisson, constitué de tôles soudées, est renforcé à l'emplacement de l'axe d'oscillation sur chacune de ses faces par une tôle (22), ainsi que sur une partie de la surface de ses côtés, par une platine en tôle forte (23). Sa partie supérieure est prolongée de manière à pouvoir recevoir un alésage qui servira au passage de l'axe de rotation (24) vers l'arrière, de la flèche télescopique. La rigidité du caisson est améliorée par des tôles parallèles (25) à sa base, soudées à l'intérieur de celui-ci et au nombre de trois.This box, made up of welded sheets, is reinforced at the location of the axis of oscillation on each of its faces by a sheet (22), as well as on a part of the surface of its sides, by a plate of strong sheet (23). Its upper part is extended so as to be able to receive a bore which will serve for the passage of the axis of rotation (24) towards the rear, of the telescopic boom. The rigidity of the box is improved by sheets parallel (25) to its base, welded inside of it and three in number.

La partie avant du caisson qui apparaît sur la figure 12 en porte à faux, présente de derrière sur la figure 13, une forme incurvée au diamètre de la couronne d'orientation sur laquelle trois galets (26) prennent appui, afin de limiter les contraintes dans l'angle que forme le caisson.The front part of the box which appears in Figure 12 in cantilever, presents from behind in Figure 13, a curved shape to the diameter of the slewing ring on which three rollers (26) are supported, in order to limit the stresses in the angle formed by the box.

A l'arrière du caisson est soudée une oreille, sur laquelle s articule par un axe, le vérin (27) qui commande le renversement de la flèche télescopique. Selon les figures 15 à 17, celle-ci est constituée d'une partie inférieure dans laquelle coulissent les deux profilés rectangulaires (28) constitutifs de son élément supérieur. Cette glissières a la forme d'un rectangle en tôles soudées, dont les largeurs sont les côtés. La face avant (29) réserve une ouverture sur toute sa hauteur, hormis une entretoise en tête et une en pied qui maintiennent l'écartement des deux côtés. Un espace de quelques centimètres est réservé entre la face arrière et le coulisseau, au moyen d'un plat (30) soudé sur la face interne de cette tôle et à sa partie haute, ainsi qu'un plat (31) de même dimension soudé à l'arrière du coulisseau à sa partie basse, qui complète ainsi le rôle de l'entretoise qui fixe son écartement. Celui-ci est assuré en partie haute par une potence (32) qui présente un porte à faux d'environ trente centimètres sur l'avant de la flèche.At the rear of the box is welded an ear, on which is articulated by an axis, the jack (27) which controls the reversal of the telescopic boom. According to Figures 15 to 17, it consists of a lower part in which slide the two rectangular sections (28) constituting its upper element. This slides has the shape of a rectangle of welded sheets, the widths of which are the sides. The front face (29) reserves an opening over its entire height, except for a spacer at the head and one at the bottom which maintain the spacing on both sides. A space of a few centimeters is reserved between the rear face and the slide, by means of a plate (30) welded on the internal face of this sheet and at its upper part, as well as a plate (31) of the same dimension welded at the rear of the slide at its lower part, which thus completes the role of the spacer which fixes its spacing. This is provided in the upper part by a bracket (32) which has a cantilever of about thirty centimeters on the front of the boom.

Les deux plats ont une fonction d'arrêt du coulissement des deux éléments. Ce mouvement est dû à l'action de deux vérins télescopiques (33) logés chacun dans une poutre de l'élément supérieur, articulés à leur base sur l'axe de renversement de la flèche et à leur sommet, sur un axe traversant les deux parties de part en part.The two plates have a function of stopping the sliding of the two elements. This movement is due to the action of two telescopic cylinders (33) each housed in a beam of the upper element, articulated at their base on the axis of reversal of the boom and at their top, on an axis crossing the two from side to side.

Un chariot (34) en forme de H de 50cm environ de hauteur, coulisse sur ces deux poutres. L'âme de ce H est placée entre elles. Les ailes sont à l'arrière et à l'avant. L'aile arrière se loge dans le vide ménagé entre le coulisseau et la glissière de la flèche, tandis que l'aile avant, plus étroite, s'inscrit dans l'ouverture ménagée sur la face avant.A H-shaped carriage (34) of approximately 50cm in height slides on these two beams. The soul of this H is placed between them. The wings are at the back and at the front. The rear wing is housed in the void formed between the slider and the boom slide, while the narrower front wing fits into the opening on the front face.

Ce mode de construction lui autorise une course possible du bas jusqu'au sommet de la flèche, en position déployée. Cette glissière est assemblée de façon démontable et sur sa face avant, elle porte deux goussets verticaux (35), de part et d'autre de l'axe vertical de l'ensemble.This construction method allows it to run from the bottom to the top of the boom in the deployed position. This slide is assembled in a removable manner and on its front face, it carries two vertical gussets (35), on either side of the vertical axis of the assembly.

Ces goussets sont alésés pour permettre le passage des deux axes de montage de la platine supportant le marteau de battage.These gussets are bored to allow the passage of the two mounting pins of the plate supporting the threshing hammer.

Un alésage supplémentaire (36) en retrait par rapport aux précédents, reçoit un axe situé au haut du corps d'un vérin (37), dont la tête est articulée sous la potence de tête de flèche.An additional bore (36) recessed from the previous ones, receives an axis located at the top of the body of a jack (37), the head of which is articulated under the jib head jib.

Ce vérin commande le coulissement du chariot.This cylinder controls the sliding of the carriage.

Sous le bâti de la pince, deux Tés (38) apparaissant sur les figures 5 et 6, coulissent par leurs ailes dans deux glissières formées de deux cornières à ailes inégales et poussés simultanément par un vérin (39) placé entre eux, ils viennent se glisser sous les palplanches tenues verticalement, afin d'éviter un glissement accidentel de celles-ci entre les mâchoires.Under the clamp frame, two Tees (38) appearing in Figures 5 and 6, slide by their wings in two slides formed by two angles with unequal wings and pushed simultaneously by a jack (39) placed between them, they come slide under the sheet piles held vertically, in order to avoid accidental sliding of these between the jaws.

Le dispositif est particulièrement destiné à manipuler, guider et mettre en fiche des palplanches et autres profilés, sur les chantiers de travaux publics ou de bâtiment.The device is particularly intended for handling, guiding and filing sheet piles and other sections, on public works or building sites.
