Description

  • [0001] [0001]
    La présente invention a trait à une pince brise-béton. The present invention relates to a breaker clamp.
  • [0002] [0002]
    Ce type d'outil est utilisé pour la démolition de structures en béton armé et monté généralement à l'extrémité de la flèche d'une pelle hydraulique au lieu et place d'un godet. This type of tool is used for the demolition of reinforced concrete structures, and generally mounted at the end of the boom of an excavator in lieu of a bucket.
  • [0003] [0003]
    Ces dispositifs sont, d'une manière générale, constitués d'une mâchoire à deux bras munis de dents, articulés sur un bâti lui-même monté rotatif et comportent, en outre, une cisaille agencée entre les bras et apte à sectionner les fers et autres armatures métalliques. These devices are, generally, consist of a jaw with teeth two arms, articulated on a frame itself mounted rotatable and further comprise a shears arranged between the arms and capable of cutting irons and other metal reinforcement.
  • [0004] [0004]
    Ces systèmes, notamment la cisaille, sont peu pratiques d'emploi et peu efficaces. These systems include the shears are few employment practices and ineffective. En effet, la cisaille est située au fond de la mâchoire et à proximité immédiate de l'un des bras de la mâchoire qui constitue l'un des deux organes de sectionnement de ladite cisaille. Indeed, the cutter is located at the bottom of the jaw and in the immediate vicinity of one of the jaw arm which is one of two of said shears severing organs.
  • [0005] [0005]
    Un tel agencement présente divers inconvénients. Such an arrangement has various disadvantages.
  • [0006] [0006]
    L'introduction des fers à sectionner à l'intérieur de la cisaille est malaisée car cette dernière se trouve au fond de la pince en un endroit très difficilement visible de la cabine de commande de l'engin ; The introduction of severing irons inside the cutter is not easy because the latter is at the bottom of the clamp in a place easily visible from the machine control cabin; de plus, l'ouverture de la cisaille est très faible en sorte qu'il faut travailler, la plupart du temps, en aveugle, tâtonner pour engager les fers et s'y reprendre à plusieurs fois pour sectionner un faisceau de fers. Moreover, the opening of the shears is very low so it must work, mostly, blind, groping for engaging irons to try several times to sever an iron beam. Enfin, l'ouverture maximale de la cisaille étant obtenue par l'ouverture maximale de la pince, cela peut poser de sérieux problèmes lorsqu'il faut sectionner des fers dans des espaces restreints, encombrés ou d'accès étroit. Finally, the maximum of the shear opening being obtained by the maximum aperture of the clamp, it can cause serious problems when it cut the irons in cramped, cluttered or narrow access.
  • [0007] [0007]
    Le but de la présente invention est de pallier ces divers inconvénients en proposant une autre combinaison de moyens assurant à la fois la fonction de pince à béton et la fonction de cisaille, de manière beaucoup plus pratique et efficace. The purpose of the present invention is to overcome these various disadvantages by proposing another combination means ensuring both the concrete clip function and the cutter function in a much more convenient and efficient.
  • [0008] [0008]
    A cet effet, l'invention a pour objet une pince brise-béton, du type comportant un bâti monté rotatif portant à la fois les organes formant pince et des organes de cisaillage, caractérisée en ce que lesdits organes de cisaillage sont constitués par au moins un bras fixe et l'un des bras de la pince, ce dernier étant articulé sur ledit bâti et agencé de façon à donner à la cisaille son ouverture maximale lorsqu'il est en position de fermeture maximale de la pince. To this end, the invention relates to a breaker clamp, of the type comprising a rotatably mounted frame carrying both the members forming a gripper and shearing members, characterized in that said shearing means are constituted by at least a fixed arm and one of the clamp arms, the latter being hinged to said frame and arranged to give the shears its maximum opening when in the maximum closed position of the clamp.
  • [0009] [0009]
    Un tel dispositif est beaucoup plus facile à manipuler et efficace car la cisaille se trouve à l'extrémité de la pince et non plus au fond de cette dernière. Such a device is much easier to handle and efficient because the cutter is at the end of the clip and not the bottom of it. Son ouverture est beaucoup plus grande et correspond à l'écartement minimal de la pince, ce qui permet de cisailler en une seule fois, après un engagement direct, franc et sans tâtonnement, plusieurs fers groupés. Its opening is much larger and corresponds to the minimum spacing of the clamp, allowing sheared once, after a direct, frank and without groping, several grouped irons.
  • [0010] [0010]
    L'invention vise également à améliorer l'efficacité des organes de la cisaille et de la pince en permettant le réglage et/ou le remplacement aisés des lames ou dents. The invention also aims to improve the efficiency of the shear members and the clamp for adjusting and / or easy replacement of blades or tines.

  • [0014] [0014]
    Les bras 4 et 5 constituent des leviers flanqués de tourillons 8 et 9 engagés dans des paliers 10 réalisés dans les deux flasques 2 et 3. The arms 4 and 5 are flanked levers pins 8 and 9 engaged in bearings 10 formed in the two flanges 2 and 3.
  • [0015] [0015]
    L'une des extrémités des bras 4 et 5, côté intérieur, porte des dents 11 montées amovibles, cependant qu'entre les autres extrémités desdits bras est agencé un vérin hydraulique à double effet 12 interposé entre les flasques 2 et 3. One of the ends of the arms 4 and 5, inner side, has teeth 11 removably mounted, however, between the other ends of said arms is arranged a hydraulic double-acting jack 12 interposed between the flanges 2 and 3.
  • [0016] [0016]
    Le débattement angulaire des bras 4 et 5 est limité par une butée 13 solidaire du bâti 1 et une lumière arquée 14 conformée dans chaque bras et dans laquelle peut coulisser la butée 13. The angular displacement of the arm 4 and 5 is limited by a stop 13 integral with the frame 1 and an arcuate slot 14 formed in each arm and wherein the stop 13 can slide.
  • [0017] [0017]
    L'un des flasques (2) comporte, d'un côté, un prolongement en forme de bras 14 dont l'extrémité constitue l'un des bras d'une cisaille dont l'autre bras est formé par le bras 5 de la pince. One of the flanges (2) has, on one side, an arm-like extension 14 whose end constitutes one of the arms of shears of which the other arm is formed by the arm 5 of the clip .
  • [0018] [0018]
    Les organes actifs de la cisaille sont constitués de lames de coupe 15 et 16 montées amovibles respectivement sur les flancs en regard des bras 5 et 14 respectivement. The active components of the shears are composed of cutting blades 15 and 16 removably mounted respectively on the facing sides of the arms 5 and 14 respectively.
  • [0019] [0019]
    L'agencement du bras 14 est tel qu'en position de fermeture maximale de la pince (4, 5) telle qu'illustrée par les figures 1 et 3, l'ouverture de la cisaille (5, 14) est maximale, alors qu'en position d'ouverture maximale de la pince (figure 2), la cisaille est complétement fermée. The arrangement of the arm 14 is such that in the maximum closed position of the gripper (4, 5) as illustrated in Figures 1 and 3, the opening of the shear (5, 14) is maximum, so that 'in the maximum opening position of the clamp (2), the shears are completely closed. Les lames 15 et 16 sont disposées aux extrémités des bras 5 et 14 afin de saisir les fers avec la plus grande ouverture possible et une plus grande facilité d'accès aux fers et de saisie de ces derniers. The blades 15 and 16 are disposed at the ends of the arms 5 and 14 to capture the chains with the greatest possible opening and greater ease of access to irons and seizure thereof.
  • [0020] [0020]
    La figure 7 illustre la forme et le montage des lames 15 et 16. Celles-ci sont constituées, conformément à l'invention, d'une plaque allongée munie sur l'une de ses faces d'une série de dents 17 dont le profil dissymétrique est déterminé de manière à retenir les fers dans la cisaille et les empêcher de glisser au dehors lors de la fermeture des bras 5, 14. Ceci permet de sectionner efficacement les fers, à l'unité ou en groupe. Figure 7 illustrates the shape and assembly of blades 15 and 16. These are formed in accordance with the invention, an elongated plate provided on one of its faces with a series of teeth 17 whose profile asymmetrical is determined to retain the irons in the shears and prevent them from slipping outside when closing the arms 5, 14. This effectively sever the fetters, individually or in groups. A cet effet, chaque dent 17 comprend un flanc 17a sensiblement vertical, par rapport au plan général de la plaque de lame, un flanc 17b légèrement incliné en direction de l'extérieur de la cisaille et un chaufrein 17c de raccordement entre les deux flancs 17a, 17b, évitant toute arête vive et donc fragile à l'extrémité des dents. To this end, each tooth 17 comprises a flange 17a substantially vertical with respect to the general plane of the blade plate, a side 17b inclined slightly toward the outside of the shears and a chaufrein 17c connecting between the two flanks 17a , 17b, avoiding sharp edges and therefore fragile at the end of the teeth.
  • [0021] [0021]
    Le montage amovible des lames 15 et 16 permet un réaffutage de l'arête de coupe par meulage de l'un des flancs latéraux des lames. The removable mounting of the blades 15 and 16 allows a resharpening of the cutting edge by grinding one of the lateral flanks of the blades.
  • [0022] [0022]
    Le réglage latéral des lames 15 et 16 sur les bras 5, 14 est possible grâce à des perçages allongés 18 réalisés dans les lames et dans lesquels sont engagés des boulons de fixation. Lateral adjustment of the blades 15 and 16 of the arms 5, 14 is possible through the elongated bores 18 made in the blades and in which are engaged fixing bolts.
  • [0023] [0023]
    Les dents 11 du brise-béton sont de préférence constituées de pièces (figure 8) comprenant un pieds d'ancrage 19 tronconique engagé dans un logement de forme correspondante ménagé dans le bras récepteur (4, 5) et retenu en place par une groupille 20. Ce montage permet de reporter sur ledit logement tronconique l'ensemble des efforts exercés sur la dent 11 dont la partie externe 21 est légèrement en retrait de la face en regard du bras porteur. The teeth 11 of the breaker are preferably made of parts (Figure 8) comprising a frustoconical anchoring legs 19 engaged in a correspondingly shaped recess provided in the receiving arms (4, 5) and held in place by a groupille 20 . This arrangement allows to postpone on said tapered housing all the forces exerted on the tooth 11, the outer portion 21 is slightly recessed from the side facing the carrier arm.
  • [0024] [0024]
    Le caractère amovible des dents 11 et des lames 15, 16 permet de remplacer des pièces endommagées et éventuellement de substituer aux pièces actuelles des pièces de caractéristiques (forme, nature du matériau) mieux adaptées aux travaux envisagés. The removable nature of the teeth 11 and blades 15, 16 makes it possible to replace damaged parts and optionally to replace the existing parts parts (shape, nature of the material) best suited to the proposed work. Actuellement celà n'est pas possible, notamment avec les dents des brise-béton connus, qui sont formées de dépôts de soudure superposées sur les bras de la pince, ces dents devant être en outre périodiquement régénérées pour cause d'usure. Currently this is not possible, especially with the teeth of known breakers, which are formed of overlapping weld deposits on the clamp arm, the teeth to be further regenerated periodically due to wear. Il est à noter qu'avec le dispositif de l'invention lorsque la pince brise-béton (4, 5) a brisé complètement par exemple une poutre en béton armée, elle se trouve alors en position complètement fermée (figure 1), la cisaille (5, 14) étant en position d'ouverture maximale et donc immédiatement prête à saisir et sectionner des fers d'armature. It should be noted that with the device of the invention when the clip breaker (4, 5) has broken completely e.g. a reinforced concrete beam, it is then in the fully closed position (Figure 1), the shears (5, 14) are in maximum open position and therefore immediately ready to grab and sever reinforcing bars. Au contraire, avec les pinces connues il faut ouvrir complétement la pince puisque la cisaille se trouve au fond de celle-ci. On the contrary, with the known clamps must fully open the clamp, since the shear is at the bottom of it. De même, en fin de cisaillage la pince se trouve en position d'ouverture maximale donc prête à intervenir. Similarly, the end of the shearing clamp is in the maximum open position so ready to intervene.
  • [0025] [0025]
    Il faut également noter que dans la pince de l'invention le fond de la pince (entre les dents 11 et le bâti 1) est bien dégagé contrairement aux dispositifs connus ce qui facilite d'autant la saisie et le travail de la pince. It should also be noted that in the clamp of the invention the bottom of the clip (between teeth 11 and the frame 1) is generated in contrast with known devices which facilitates all the seizure and the work of the clamp.
  • [0026] [0026]
    Les butées de fin de course (13, 14) sont nécessaires, du fait que les bras 4 et 5 sont libres en rotation, afin que dans leurs positions extrêmes, d'ouverture et de fermeture, lesdits bras 4 et 5 soient symétriques par rapport à l'axe de la pince et que la cisaille effectue convenablement son travail. limit stops (13, 14) are needed, because the arms 4 and 5 are free to rotate, so that in their extreme positions, opening and closing, said arms 4 and 5 are symmetrical in relation to the axis of the clamp and the shear properly carries out its work.
  • [0027] [0027]
    La figure 4 illustre une variante du dispositif de la figure 3 selon laquelle un second bras 14′, parallèle au bras 14, est prévu à l'aide d'un prolongement du flasque 3. Ce bras 14′ est muni d'une lame de coupe 16′ parallèle à la lame 16, le bras 5 de la pince se mouvant entre les deux bras fixes 14, 14′. 4 illustrates a variant of the device of Figure 3 wherein a second arm 14 ', parallel to the arm 14 is provided with an extension of the flange 3. This arm 14' is provided with a blade section 16 'parallel to the blade 16, the arm 5 of the clip moving between two fixed arms 14, 14'.
  • [0028] [0028]
    Dans le mode de réalisation de la figure 5, la pince brise-béton comporte un bras 5 mobile constituant également l'un des éléments de la cisaille, exactement comme dans le mode de réalisation de la figure 3, mais ce bras 5 coopère avec un bras 4′ fixe, et non plus mobile, et constitué à partir d'un prolongement des deux flasques 2 et 3. In the embodiment of Figure 5, the breaker comprises a movable clamp arm 5 also constituting one of the shear elements, just like in the embodiment of Figure 3, but the arm 5 cooperates with a arm 4 fixed, rather than movable and formed from an extension of the two flanges 2 and 3.
  • [0029] [0029]
    Le vérin 12 de commande du bras 5 est ancré en 22 sur le bâti 1. The cylinder controller 12 of the arm 5 is anchored at 22 on the frame 1.
  • [0030] [0030]
    Enfin, la figure 6 illustre une variante du dispositif de la figure 5 dans laquelle le bras fixe 14 de la cisaille est doublé d'un second bras fixe 14′ comme dans le mode de réalisation de la figure 4, le bâti 1 présentant ainsi une forme générale de U. Finally, Figure 6 illustrates a variant of the device of Figure 5 in which the fixed arm 14 of the cutter is coupled with a second fixed arm 14 'as in the embodiment of Figure 4, the frame 1 and having a generally U-shaped
  • [0031] [0031]
    D'une manière générale l'invention n'est évidemment pas limitée aux modes de réalisation représentés et décrits ci-dessus mais en couvre au contraire toutes les variantes notamment en ce qui concerne les formes et agencements des lames 16, des dents 11 et des divers bras 4, 5, 14, 4′, 14′. In general the invention is of course not limited to the embodiments shown and described above but on the contrary covers all variants notably as regards shapes and arrangements of the blades 16, teeth 11 and various arms 4, 5, 14, 4 ', 14'.
