The hydraulic jacks and the rotation plates are controlled by respective control levers.

Description

L'invention concerne un appareil pour fixer des plaques sous un plafond au moyen de chevilles ancrées dans ledit plafond.The invention relates to an apparatus for fixing plates under a ceiling by means of plugs anchored in said ceiling.

La pose de plaques sous des plafonds maçonnés, pour assurer l'isolation acoustique ou la sécurité contre l'incendie, par exemple, est une opération particulièrement pénible pour le personnel préposé à cette tâche.The installation of plates under masonry ceilings, to ensure sound insulation or fire safety, for example, is a particularly painful operation for the personnel in charge of this task.

En effet, l'opérateur, juché sur un échafaudage ou un escabeau, doit maintenir la plaque à fixer contre le plafond, pendant qu'il effectue les trous dans le plafond à travers la plaque, et qu'il plante les chevilles au moyen d'une visseuse ou d'un marteau. Dans le cas où la plaque est de grande dimension, l'opération de pose d'une plaque peut nécessiter deux opérateurs dont les actions sont coordonnées. Après la pose d'une plaque, il faut redescendre de l'échafaudage ou de l'escabeau et déplacer ce dernier pour permettre la pose de la plaque suivante. On conçoit que dans ces conditions de travail, il soit difficile pour deux opérateurs de réaliser plus de 35 m2 de pose de plaques par journée de travail.Indeed, the operator, perched on a scaffolding or a stepladder, must hold the plate to be fixed against the ceiling, while he makes the holes in the ceiling through the plate, and that he plants the ankles by 'a screwdriver or hammer. In the case where the plate is large, the operation of laying a plate may require two operators whose actions are coordinated. After the installation of a plate, it is necessary to descend from the scaffolding or the stepladder and move the latter to allow the installation of the next plate. It is understood that under these working conditions, it is difficult for two operators to carry out more than 35 m 2 of laying of plates per working day.

Le but de l'invention est de fournir un appareil de pose de plaques sous un plafond au moyen de chevilles ancrées dans ledit plafond, qui diminue de façon considérable la pénibilité de la tâche et qui améliore la productivité.The object of the invention is to provide a device for laying plates under a ceiling by means of dowels anchored in said ceiling, which considerably reduces the arduousness of the task and which improves the productivity.

L'invention concerne donc un appareil pour fixer des plaques sous un plafond au moyen de chevilles ancrées dans ledit plafond.The invention therefore relates to an apparatus for fixing plates under a ceiling by means of plugs anchored in said ceiling.

Selon l'invention, cet appareil est caractérisé par le fait qu'il comporte :

  • un chariot susceptible de rouler sur le sol ;
  • une plate-forme verticalement mobile surmontant le chariot avec interposition de moyens de levage de ladite plate-forme ;
  • un support de plaque disposé au-dessus de ladite plate-forme, ledit support de plaque étant destiné à supporter une plaque à fixer au plafond et à l'immobiliser contre le plafond pendant les opérations de fixation ;
  • une table verticalement mobile disposée entre ladite plate-forme et ledit support de plaque, des moyens de levage de ladite table étant interposés entre ladite table et ladite plate-forme ;
  • une pluralité d'outils disposés en rangs et colonnes sur ladite table, chaque outil comportant une perceuse pour percer un trou dans le plafond à travers la plaque à fixer, et un marteau pneumatique pour planter une cheville dans le trou réalisé par ladite perceuse ;
  • des moyens de pivotement pour faire pivoter à l'unisson lesdits outils entre une première position dans laquelle les mèches des perceurs sont dirigées vers le plafond et les marteaux sont escamotés, et une deuxième position dans laquelle les marteaux sont positionnés pour planter les chevilles et les perceuses sont escamotées ; et
  • des moyens de commande des moyens de levage de la plate-forme, des moyens de levage de la table, des moyens de pivotement des outils, et des outils.
    • According to the invention, this device is characterized in that it comprises:
  • a cart capable of rolling on the ground;
  • a vertically mobile platform surmounting the carriage with interposition of means for lifting said platform;
  • a plate support arranged above said platform, said plate support being intended to support a plate to be fixed to the ceiling and to immobilize it against the ceiling during the fixing operations;
  • a vertically movable table disposed between said platform and said plate support, means for lifting said table being interposed between said table and said platform;
  • a plurality of tools arranged in rows and columns on said table, each tool comprising a drill for drilling a hole in the ceiling through the plate to be fixed, and a pneumatic hammer for planting a dowel in the hole made by said drill;
  • pivoting means for pivoting in unison said tools between a first position in which the drill bits are directed towards the ceiling and the hammers are retracted, and a second position in which the hammers are positioned to plant the dowels and the drills are retracted; and
  • means for controlling the means for lifting the platform, means for lifting the table, means for pivoting the tools, and tools.

    • L'appareil selon l'invention comporte ainsi des moyens propres pour supporter une plaque à fixer et la maintenir contre le plafond pendant les opérations de perçage et de fixation des chevilles.The apparatus according to the invention thus comprises its own means to support a plate to fix and hold it against the ceiling during drilling and anchoring operations.

    L'opérateur dispose une plaque sur le support de plaque qui a été préalablement abaissé par descente de la plate-forme. Il déplace légèrement, si besoin est, le chariot pour que la plaque puisse être positionnée à l'endroit souhaité, avant de l'immobiliser complètement par une montée supplémentaire de la plate-forme. Il commande ensuite la mise en route des perceuses, puis des marteaux après avoir fait pivoter les outils dans la position adéquate, avoir remonté la table, et s'être assuré que des chevilles sont installées sur les marteaux. Lorsque la plaque est fixée, il lui suffit de redescendre la plate-forme et la table, de déplacer le chariot sous la zone suivante de plafond à habiller et de recommencer un nouveau cycle de pose.The operator has a plate on the plate support which has previously lowered by lowering the platform. He moves slightly, if necessary, the carriage so that the plate can be positioned at the desired location, before immobilizing it completely by an additional rise of the platform. He then orders the starting the drills, then hammers after rotating tools in the correct position, having reassembled the table, and having assured that dowels are installed on the hammers. When the plate is fixed, he just has to lower the platform and the table, move the cart under the next ceiling area to be dressed and start a new laying cycle.

    L'appareil selon l'invention comporte préférentiellement les avantageuses dispositions suivantes :

  • Les moyens de levage de la plate-forme comportent un premier vérin hydraulique.
  • Les moyens de levage de la table comportent également un vérin hydraulique.

    Les figures 1 et 2 montrent un appareil 1 pour fixer des plaques 2, de forme rectangulaire contre la face inférieure 3 d'un plafond 4 maçonné. La référence 2a désigne une plaque déjà fixée au plafond et la référence 2b désigne l'emplacement de la plaque suivante à fixer.Figures 1 and 2 show an apparatus 1 for fixing plates 2, rectangular against the underside 3 of a masonry ceiling 4. Reference 2a designates a plate already fixed to the ceiling and reference 2b indicates the location of the next plate to be attached.

    L'appareil comporte essentiellement un chariot 5 monté sur roues 6 ou roulettes pour permettre son déplacement sur le sol 7. Sur la face supérieure du chariot 5 est monté le cylindre 8 d'un premier vérin hydraulique dont la tige 9 est susceptible de s'étendre vers le haut par actionnement d'une manette de commande 10. Le chariot 5 est en outre avantageusement équipé d'une rambarde 11 ayant le gabarit du chariot 5 et qui permet de déplacer facilement le chariot 5. Cette rambarde peut supporter les diverses manettes de commande de l'appareil 1.The apparatus essentially comprises a carriage 5 mounted on wheels 6 or casters to allow its movement on the ground 7. On the upper face of the carriage 5 is mounted the cylinder 8 of a first cylinder hydraulic whose rod 9 is capable of extending upward by actuation of a control lever 10. The carriage 5 is furthermore advantageously equipped with a guardrail 11 having the template of the carriage 5 and which allows the carriage 5 to be easily moved. This guardrail can support the various control levers of the device 1.

    A l'extrémité supérieure de la tige 9 est fixée une plate-forme horizontale 12 qui, dans l'exemple montré sur les figures 1 et 2, se présente sous la forme d'une poutre rigide qui s'étend dans le sens de la plus grande longueur du chariot 5.At the upper end of the rod 9 is fixed a platform horizontal 12 which, in the example shown in Figures 1 and 2, is has the form of a rigid beam which extends in the direction of the longer length of carriage 5.

    Aux extrémités de cette poutre 12 sont prévus deux ressorts à gaz 13a et 13b dont les tiges 14a et 14b dirigées vers le haut comportent à leur extrémité supérieure des plaques horizontales 15a et 15b sur lesquelles l'opérateur dispose la plaque 2 qui doit être fixée à l'emplacement 2b. Il est à noter que les plaques horizontales 15a et 15b peuvent être remplacées par un support de plaque, ayant le gabarit d'une plaque 2 qui se présente sous la forme d'une grille ou qui comporte des ouvertures pour permettre le passage des mèches des perceuses destinées à faire des trous dans le plafond 4 à travers la plaque à fixer 2.At the ends of this beam 12 are provided two springs to gas 13a and 13b whose rods 14a and 14b directed upwards comprise at their upper end horizontal plates 15a and 15b on which the operator has the plate 2 which must be fixed to location 2b. It should be noted that the horizontal plates 15a and 15b can be replaced by a plate support, having the template of a plate 2 which is in the form of a grid or which has openings to allow the drill bits to pass through intended to make holes in the ceiling 4 through the plate to be fixed 2.

    Sur la plate-forme horizontale 12, à l'aplomb du premier vérin hydraulique, est fixé le cylindre 16 d'un deuxième vérin hydraulique dont la tige 17 est dirigée vers le haut. Ce deuxième vérin hydraulique a une dimension et une course nettement inférieures à celles du premier vérin hydraulique et il est commandé par une deuxième manette 18 montée par exemple sur la rambarde 11.On the horizontal platform 12, directly above the first cylinder hydraulic, the cylinder 16 of a second hydraulic cylinder is fixed, the rod 17 is directed upwards. This second hydraulic cylinder has a dimension and a stroke much smaller than those of the first cylinder hydraulic and it is controlled by a second lever 18 mounted by example on the railing 11.

    A l'extrémité supérieure de la tige 17 du deuxième vérin hydraulique, est fixée une table horizontale 20. Cette table 20, réalisée à partir de longerons et de traverses rigides, ainsi qu'à partir de tubes alignés, par mécano-soudage, supporte une pluralité d'outils 21 disposés en rangs et colonnes, selon les dimensions habituelles des plaques à fixer par l'appareil 1. Sur les figures 1 et 2, on voit que l'appareil 1 comporte deux rangs latéraux 22a et 22b, et chaque rang comporte trois outils référencés 21a, 21b et 21c.At the upper end of the rod 17 of the second cylinder hydraulic, a horizontal table 20 is fixed. This table 20, produced at from rigid beams and sleepers, as well as from tubes aligned, by mechanical welding, supports a plurality of tools 21 arranged in rows and columns, according to the usual dimensions of the plates to be fixed by the device 1. In Figures 1 and 2, we see that the device 1 has two lateral rows 22a and 22b, and each row has three tools referenced 21a, 21b and 21c.

    Chaque outil 21 comporte une perceuse 23 et un marteau 24 décalé de 90° par rapport à la perceuse correspondante 23.Each tool 21 includes a drill 23 and a hammer 24 offset 90 ° from the corresponding drill 23.

    Chaque outil 21 est monté fixe en rotation sur un arbre 25 lequel est monté pivotant dans une série de tubes formant les bords longitudinaux de la table 20.Each tool 21 is mounted fixed in rotation on a shaft 25 which is pivotally mounted in a series of tubes forming the edges table 20.

    La référence 26 désigne un plateau de rotation pneumatique fixé à l'extrémité de chaque arbre 25 et qui permet de faire pivoter l'arbre 25 d'un angle prédéterminé, par exemple de 90°, dans un sens ou dans l'autre, et par le fait même de faire pivoter les outils 21 portés par cet arbre 25, entre une première position dans laquelle les mèches 23a des perceuses 23 sont dirigées vers le haut, et les marteaux 24 sont escamotés et disposés à l'horizontale, et une deuxième position, dans laquelle les marteaux 24 sont en position pour planter des chevilles 24a dans les trous perforés par les perceuses 23 et les perceuses sont escamotées et disposées à l'horizontale.Reference 26 designates a pneumatic rotation plate attached to the end of each shaft 25 and which allows the shaft 25 to pivot by a predetermined angle, for example 90 °, in one direction or in the other, and by the very fact of rotating the tools 21 carried by this shaft 25, between a first position in which the wicks 23a of the 23 drills are facing up, and the hammers 24 are retracted and arranged horizontally, and a second position, in which the hammers 24 are in position to plant pegs 24a in the holes drilled by the drills 23 and the drills are retracted and arranged horizontally.

    Sur les figures 1 et 2, les perceuses 23 sont en position de perçage et présentent leurs mèches vers le haut, et les manteaux 24 sont disposés à l'horizontale vers l'extérieur de la table 20. Cette disposition permet à l'opérateur de positionner des chevilles 24a sur les marteaux 24.In FIGS. 1 and 2, the drills 23 are in the position of piercing and have their wicks up, and coats 24 are arranged horizontally outward from the table 20. This arrangement allows the operator to position pins 24a on hammers 24.

    Si partant de la première position montée sur la figure 2, les plateaux de rotation pneumatiques 26 font pivoter les arbres 25 vers la deuxième position, les perceuses 23 viennent se positionner à l'horizontale avec les mèches 23a dirigées vers la plan médian de la table 20 et les marteaux 24 se positionnent à la verticale, les chevilles 24a étant dirigées vers le haut dans l'alignement des trous réalisés par les perceuses 23. Cette disposition évite au personnel de cogner malencontreusement dans les mèches 23a.If starting from the first position mounted in Figure 2, the pneumatic turntables 26 rotate the shafts 25 toward the second position, the drills 23 are positioned horizontally with the wicks 23a directed towards the median plane of the table 20 and the hammers 24 are positioned vertically, the pins 24a being directed upwards in alignment with the holes made by the drills 23. This provision prevents staff from accidentally bumping into wicks 23a.

    Les perceuses 23 sont montées sur les arbres 25 par l'intermédiaire de ressorts à gaz 27, qui encaissent les efforts de percussion lors du perçage des trous dans le plafond 4, à travers la plaque 2.The drills 23 are mounted on the shafts 25 by through gas springs 27, which absorb the efforts of percussion when drilling holes in the ceiling 4, through the plate 2.

    La référence 28 désigne une manette de commande montée sur la rambarde 11 qui commande un distributeur d'air comprimé vers les deux plateaux de rotation pneumatique 26.Reference 28 designates a mounted control handle on the railing 11 which controls a compressed air distributor towards the two pneumatic rotation plates 26.

    Le fonctionnement de l'appareil 1 va maintenant être décrit :The operation of the device 1 will now be described:

    Au début d'un cycle de pose d'une plaque 2, les tiges 9 et 17 du premier vérin hydraulique et du deuxième vérin hydraulique sont rétractées dans leur cylindre respectif 8 et 16, ainsi que cela est montré sur la figure 1. Dans cette position, les tiges 14a et 14b des ressorts à gaz sont en extension maximale, et les ressorts à gaz 27 supportant les perceuses 23 sont également en extension maximale. Les arbres 25 sont dans la première position.At the start of a plate 2 installation cycle, rods 9 and 17 the first hydraulic cylinder and the second hydraulic cylinder are retracted into their respective cylinders 8 and 16, as is shown in Figure 1. In this position, the rods 14a and 14b of the gas springs are fully extended, and gas springs 27 supporting the drills 23 are also in maximum extension. The 25 shafts are in the first position.

    On place alors le chariot 5 sous l'emplacement 2b qui doit recevoir une plaque 2. On pose une plaque 2 sur les plaques de support horizontales 15a et 15b, puis à l'aide de la manette de commande 10, on actionne le premier vérin. La tige 9 sort du cylindre 8 et fait monter la plate-forme 12, ainsi que cela est montré sur la figure 2. The carriage 5 is then placed under the location 2b which must receive a plate 2. A plate 2 is placed on the support plates horizontal 15a and 15b, then using the control lever 10, we operates the first cylinder. The rod 9 comes out of the cylinder 8 and causes the platform 12, as shown in Figure 2.

    Lorsque la plaque 2 se trouve pratiquement dans l'emplacement 2b, on arrête le fonctionnement du premier vérin et on peut ajuster le positionnement de la plaque 2 en déplaçant manuellement le chariot 5 de la distance nécessaire.When the plate 2 is practically in location 2b, we stop the operation of the first cylinder and we can adjust the positioning of plate 2 by manually moving the carriage 5 of the required distance.

    Lorsque la plaque 2 est bien positionnée sous l'emplacement 2b, on actionne de nouveau le premier vérin au moyen de la manette 10, ce qui comprime les ressorts à gaz 13a et 13b. Lorsque la compression des ressorts à gaz 13a et 13b a atteint un certain taux, on immobilise la tige 9 par rapport au cylindre 8. Il est à noter que le taux de compression des ressorts à gaz 13a et 13b pourrait agir automatiquement sur l'arrêt de l'alimentation du premier vérin hydraulique. Dans cette position les ressorts à gaz 13a et 13b, le premier vérin hydraulique et le chariot 5 agissent à la manière d'un étai qui retient et applique la plaque 2 à poser contre la face inférieure 3 du plafond ou plancher supérieur 4. Dans cette position, la plate-forme 12 se trouve par construction à une distance prédéterminée de la face inférieure de la plaque 2 à poser.When plate 2 is correctly positioned under the location 2b, the first jack is again actuated by means of the lever 10, which compresses the gas springs 13a and 13b. When compression gas springs 13a and 13b has reached a certain rate, the immobilized rod 9 relative to cylinder 8. It should be noted that the rate of compression of gas springs 13a and 13b could act automatically on stopping the supply of the first cylinder hydraulic. In this position the gas springs 13a and 13b, the first hydraulic cylinder and carriage 5 act like a forestay which retains and applies the plate 2 to be placed against the underside 3 of the ceiling or upper floor 4. In this position, the platform 12 is found by construction at a predetermined distance from the underside of plate 2 to install.

    Les dimensions des perceuses 23, des mèches 23a et des ressorts à gaz 27 sont calculées de telle manière que la tige 17 du deuxième vérin hydraulique étant rétractée, les extrémités des mèches 23a se trouvent alors au voisinage immédiat de la plaque 2.The dimensions of the drills 23, the bits 23a and the gas springs 27 are calculated such that the rod 17 of the second hydraulic cylinder being retracted, the ends of the wicks 23a are then in the immediate vicinity of the plate 2.

    On met alors les perceuses en fonction au moyen d'un interrupteur électrique, non montré sur les dessins, puis on fait sortir la tige 17 de son cylindre 16, en actionnant le deuxième vérin hydraulique au moyen de la manette de commande 18. Au cours de la montée de la table 20, les mèches 23a traversent d'abord la plaque 2 située à l'emplacement 2a, puis les ressorts à gaz 27 se compriment et exercent une force sur les mèches 23a qui percent alors un trou dans le plafond 4 par percussion. Le deuxième vérin hydraulique est dimensionné pour que son extension maximale crée un trou d'une profondeur suffisante pour permettre l'ancrage des chevilles 24a.The drills are then put into operation by means of a electric switch, not shown in the drawings, then remove the rod 17 of its cylinder 16, by actuating the second hydraulic cylinder at by means of the control lever 18. During the rise of the table 20, the wicks 23a first pass through the plate 2 located at the location 2a, then the gas springs 27 compress and exert a force on the wicks 23a which then pierce a hole in the ceiling 4 by percussion. The second hydraulic cylinder is dimensioned so that its maximum extension creates a hole of sufficient depth to allow the anchors 24a to be anchored.

    Après le perçage des trous, on redescend la table 20 supportée par la tige 17, on arrête les perceuses 23, puis on fait pivoter les deux arbres 25 de 90° au moyen des plateaux de rotation pneumatiques 26, en manoeuvrant la manette de commande 28. Les marteaux 24 prennent alors la position occupée précédemment par les perceuses 23. After drilling the holes, we lower the supported table 20 by rod 17, the drills 23 are stopped, then the two are pivoted shafts 25 of 90 ° by means of the pneumatic rotation plates 26, in operating the control lever 28. The hammers 24 take then the position previously occupied by the drills 23.

    Les marteaux 24 présentent sur leur face éloignée de l'arbre 24 une cheville 24a. On remonte de nouveau la table 20 en agissant sur la manette de commande 18, les extrémités des chevilles 24a pénètrent dans les trous formés dans la plaque, puis on actionne les marteaux 24, en agissant sur une manette de commande, non montrée sur les dessins. La plaque 2 est alors fixée au plafond 4. Il ne reste plus qu'à redescendre la table 20 et la plate-forme 12 en agissant sur les manettes de commande 18 et 10.The hammers 24 have on their face remote from the shaft 24 a pin 24a. We go up again the table 20 by acting on the control lever 18, the ends of the plugs 24a penetrate in the holes formed in the plate, then the hammers 24 are actuated, by acting on a control lever, not shown in the drawings. The plate 2 is then fixed to the ceiling 4. It only remains to descend the table 20 and platform 12 by acting on the control levers 18 and 10.

    L'appareil 1 est de nouveau prêt pour la pose d'une autre plaque 12.Device 1 is again ready for the installation of another plate 12.

    La figure 3 montre la position du marteau 24 lorsque la tige 17 est en extension maximale. La face d'extrémité 31 du marteau 24 est au voisinage immédiat de la plaque 2 à fixer. Le marteau 24 comporte un cylindre 32 dans lequel est monté coulissant un piston 34, chargé par un ressort de rappel 35. La chambre supérieure 36 est en communication permanente avec l'extérieure grâce à l'orifice 37, la chambre inférieure 38 est en communication par l'orifice 39 avec un distributeur 40 à deux positions qui permet l'alimentation d'un air comprimé dans la chambre inférieure 38 ou la mise à l'échappement de cette dernière.Figure 3 shows the position of the hammer 24 when the rod 17 is in maximum extension. The end face 31 of the hammer 24 is at immediate vicinity of plate 2 to be fixed. The hammer 24 has a cylinder 32 in which a piston 34 is slidably mounted, loaded by a return spring 35. The upper chamber 36 is in communication permanent with the exterior thanks to the orifice 37, the lower chamber 38 is in communication through port 39 with a distributor 40 in two positions which allow the supply of compressed air into the chamber lower 38 or the exhaust of the latter.

    En position d'attente du marteau 24, comme représenté sur la figure 3, l'extrémité supérieure de la tige 33 du piston 34 affleure dans le fond d'une cavité 41 débouchant dans la face d'extrémité 31. Cette cavité 41 a un diamètre au moins égal à la tête 42 d'une cheville 43. Le fond de la cavité comporte un aimant 44 qui permet la retenue de la cheville 43, qui est métallique.In the hammer 24 standby position, as shown in the Figure 3, the upper end of the rod 33 of the piston 34 is flush with the bottom of a cavity 41 opening into the end face 31. This cavity 41 has a diameter at least equal to the head 42 of a pin 43. The bottom of the cavity includes a magnet 44 which allows the anchor 43 to be retained, which is metallic.

    La remontée de la table 20 a permis l'introduction de la partie supérieure de la cheville dans le trou 45 traversant la plaque 2. Lorsqu'on injecte de l'air comprimé dans la chambre inférieure 38, le piston 34 se déplace vers le haut, et pousse la cheville 43 vers le haut. Cette cheville 43 comporte un coin 47 qui vient frapper le fond du trou borgne 48 ménagé dans le plafond 4. Le choc qui en résulte provoque l'encastrement de l'extrémité supérieure de la cheville 43 dans le plafond 4.The rise of table 20 allowed the introduction of the part upper of the dowel in the hole 45 passing through the plate 2. When injects compressed air into the lower chamber 38, the piston 34 moves up, and pushes ankle 43 up. This peg 43 has a wedge 47 which strikes the bottom of the blind hole 48 provided in the ceiling 4. The resulting shock causes the embedding of the upper end of the pin 43 in the ceiling 4.

    La figure 4 montre le schéma de principe d'un plateau de rotation pneumatique 26. Ce plateau comporte un cylindre 60 coaxial à l'arbre 25 et solidaire de la table 20. L'arbre 25 traverse le cylindre 60 et est équipé d'un secteur de disque 61 qui s'étend sur 270° environ entre deux faces radiales 62a et 62b. Une paroi radiale 63 solidaire du cylindre 60 s'étend dans l'espace vide séparant les deux parois radiales 62a et 62b. Cette paroi 63 partage l'espace vide en deux chambres de volume variables 63a et 63b dans lesquelles débouchent deux orifices 64a et 64b situés au voisinage de la paroi radiale 63. Ces orifices 64a et 64b sont en communication avec un distributeur 65 à deux positions commandé par la manette 28 qui permet de mettre l'une des chambres 63a et 63b en liaison avec une source d'air comprimé et l'autre à l'échappement.Figure 4 shows the block diagram of a pneumatic rotation 26. This plate comprises a cylinder 60 coaxial with the shaft 25 and integral with the table 20. The shaft 25 passes through the cylinder 60 and is equipped with a disk sector 61 which extends over approximately 270 ° between two radial faces 62a and 62b. A radial wall 63 integral with the cylinder 60 extends in the empty space separating the two radial walls 62a and 62b. This wall 63 divides the empty space into two volume chambers variables 63a and 63b into which two orifices 64a and 64b open located in the vicinity of the radial wall 63. These orifices 64a and 64b are in communication with a two-position distributor 65 controlled by the lever 28 which allows to put one of the chambers 63a and 63b in connection to one source of compressed air and the other to the exhaust.

    Dans le mode de réalisation décrit ci-dessus, les outils 21 comportent des perceuses 23 et des marteaux 24. Il est évident pour l'homme du métier que les marteaux 24 peuvent être remplacés éventuellement par des visseuses.In the embodiment described above, the tools 21 include drills 23 and hammers 24. It is obvious to those skilled in the art that hammers 24 can be replaced possibly by screwdrivers.

    Les perceuses 23 sont de préférence des perceuses à percussion qui peuvent être entraínées soit par des moteurs électriques, soit par des moteurs à air comprimé.The drills 23 are preferably drills with percussion which can be driven either by electric motors, either by compressed air motors.

    Les générateurs d'air comprimé et de fluide hydraulique sous pression peuvent évidemment être montés sur le chariot 5, ou installés sur le chariot lors de l'opération de pose.Compressed air and hydraulic fluid generators under pressure can obviously be mounted on the carriage 5, or installed on the carriage during the installation operation.
