Abstract

The machine (1) has a traction system including an electric gear motor (2) attached to a base-plate (3) of a chassis. The motor has a speed variator and a storage reel (14) on which an electric cable supplying power to the motor is placed. A reducer (4) of the motor emerges from a transversal traction axle (5) whose ends are terminated by toothed pinions. The pinions transmit movement, through traction chains (8), to toothed crowns (12) of traction wheels (10, 11) located under front sides of the machine, so as to cause displacement of the machine in two directions.

Le présent Brevet d'Addition porte sur des améliorations introduites dans l'objet du Brevet d'Invention n° P200700250 pour des « Perfectionnements introduits dans les machines pour la fabrication en continu de pièces de béton précontraintes ou armées ».The present Addition Patent relates to improvements introduced in the subject matter of the Patent of Invention No. P200700250 for "Improvements introduced into machines for the continuous manufacture of prestressed or reinforced concrete parts".

Le présent Brevet d'Addition porte sur l'amélioration introduite dans les machines pour l'élaboration en continu de pièces de béton précontraintes ou armées, des machines essentiellement caractérisées par le fait qu'elles sont constituées d'un châssis déplaçable sur des rails qui définissent la piste de fabrication, et par le fait qu'elles sont pourvues des éléments nécessaires à la réception du béton (une surtrémie mobile), pour l'alimentation du moule vibrateur (trémie fixe), le moule vibrateur mentionné, pourvu d'une série de noyaux, et près de celui-ci un moule de rétention, et un dernier moule servant d'affineur, également pourvu de noyaux.The present Addition Patent relates to the improvement introduced in machines for the continuous production of prestressed or reinforced concrete parts, machines essentially characterized by the fact that they consist of a chassis displaceable on rails which define the manufacturing track, and by the fact that they are provided with the elements necessary for the reception of the concrete (a mobile surtremma), for the feeding of the vibrator mold (fixed hopper), the vibrator mold mentioned, provided with a series of cores, and near it a retention mold, and a last mold serving as a refiner, also provided with cores.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'amélioration objet de ce brevet d'addition consiste à doter la machine d'élaboration en continu et déplaçable sur des rails, d'un système de traction propre pour son déplacement le long des pistes de fabrication, par la motorisation de ses roues avant de translation.The improvement object of this patent of addition is to provide the machine continuous and movable on rails, a clean traction system for its movement along the production tracks, by the motorization of its front wheels translation.

L'application de ce système de traction permet d'éliminer le système traditionnel utilisé actuellement sur ce type de machines déplaçables, consistant en un mécanisme de câble d'entraînement enroulable sur tambour, actionné par motoréducteur. Le nouveau système motorisé autonome permet d'éliminer le câble d'entraînement, déroulé tout le long de la piste de fabrication, installation extrêmement délicate étant donné la longueur de ladite piste (entre 150 et 200 m.) en évitant les problèmes découlant dudit déroulage, tels que les tractions du câble, du fait de sa propre élasticité et de sa caténaire, ainsi que la variation de vitesse de déplacement qui se produit habituellement à mesure qu'augmente la quantité de câble enroulé sur le tambour d'entraînement mentionné.The application of this traction system eliminates the traditional system currently used on this type of movable machines, consisting of a drum-driven drive cable mechanism actuated by geared motor. The new autonomous motorized system makes it possible to eliminate the training cable, unrolled all along the production track, an extremely delicate installation given the length of said track (between 150 and 200 m.) Avoiding the problems arising from this unwinding. , such as cable pulls, because of its own resilience and catenary, as well as the movement speed variation that usually occurs as the amount of cable wound on the drive drum mentioned increases.

L'application du système qui est décrit ci-après, permet d'absorber les oscillations ou inerties que produit la surtrémie mobile d'alimentation lorsqu'elle se déplace pour remplir son office, évitant ainsi que la machine n'accélère ou que sa vitesse n'augmente du fait de la poussée exercée par le béton lorsqu'il est extrudé. On obtient donc, avec ce nouveau système de traction, l'acquisition par la machine d'une vitesse de progression uniforme, variable et contrôlable à volonté, ce qui a des répercussions positives sur l'uniformité et la finition des pièces fabriquées.The application of the system, which is described below, makes it possible to absorb Oscillations or inertia produced by the mobile superstructure when it moves to fill its galley, thus preventing the machine from accelerating or increasing its speed due to the thrust exerted by the concrete when it is extruded . Thus, with this new traction system, the acquisition by the machine of a uniform, variable and controllable speed of progression is obtained at will, which has a positive effect on the uniformity and the finish of the manufactured parts.

Enfin, le système de traction objet de cette invention, permet d'inverser le sens de progression de la machine, ce qui sera d'une grande utilité dans les moments où, en raison d'une coupure ou d'une défaillance d'alimentation en béton, on devra faire reculer la machine à une distance déterminée pour reprendre à nouveau la fabrication, déplacement impossible à réaliser avec les machines pourvues de l'actuel système de déplacement par câble d'entraînement.Finally, the traction system that is the subject of this invention makes it possible to reverse the direction of progression of the machine, which will be of great use at times when, due to a power failure or failure. in concrete, it will be necessary to move the machine back a certain distance to take again the manufacture, displacement impossible to realize with the machines equipped with the current system of displacement by cable of drive.
