Description

La présente invention est relative à une machine de construction de chaussée du type finisseur, comportant notamment une trémie de réception des enrobés bitumineux et un réservoir secondaire pour je stockage d'une substance fluide, telle que par exemple une émulsion d'accrochage d'enrobés bitumineux sur la surface d'une route.The present invention relates to a paver construction machine of the paver type, comprising in particular a hopper for receiving bituminous mixes and a secondary tank for the storage of a fluid substance, such as for example an emulsion for bonding mixes. bituminous on the surface of a road.

Les machines de construction de chaussée du type finisseur sont depuis longtemps connues. Elles comportent sur un châssis monté sur des moyens de déplacement, des moyens d'épandage des enrobés bitumineux et des moyens d'alimentation desdits moyens d'épandage, ces moyens d'alimentation comportant notamment à une extrémité du finisseur, une trémie dans laquelle des camions bennes déversent des enrobés chauds. Les enrobés déversés sont ensuite transportés par un tapis convoyeur jusqu'auxdits moyens d'épandage.Paver-type paving machines have long been known. They comprise, on a chassis mounted on displacement means, means for spreading bituminous mixes and means for feeding said spreading means, these feeding means comprising in particular at one end of the paver, a hopper in which dump trucks dump hot asphalt. The spilled mixes are then transported by a conveyor belt to said spreading means.

Il a été récemment proposé par la demanderesse, notamment dans ses demandes de brevet français déposées sous les numéros 90-07 807, 90-10 141 et 90-13 475, d'intégrer à ces machines de construction de chaussée un dispositif permettant à la même machine d'épandre également une émulsion d'accrochage des enrobés bitumineux. Les machines de construction de chaussée proposées par ces différentes demandes de brevet réalisent ainsi l'application simultanée sur la surface de la route d'une émulsion d'accrochage et du revêtement de chaussée correspondant.It has recently been proposed by the applicant, in particular in its French patent applications filed under the numbers 90-07 807, 90-10 141 and 90-13 475, to integrate into these pavement construction machines a device allowing the same machine also spreads a bonding emulsion of bituminous mixes. The pavement construction machines proposed by these various patent applications thus realize the simultaneous application on the road surface of a bonding emulsion and the corresponding pavement coating.

En dehors du dispositif d'épandage de l'émulsion d'accrochage, il est nécessaire de prévoir sur ces machines un stockage particulier pour ladite émulsion. Différentes solutions ont déjà été proposées par la demanderesse à cet égard. Dans une solution particulière notamment, le réservoir d'émulsion est monté sur des vérins, au-dessus de la cabine de pilotage du finisseur. En cours d'épandage, le réservoir est maintenu en hauteur par les vérins et, pour le transport du finisseur, le réservoir est rapproché du châssis.Apart from the device for spreading the bonding emulsion, it is necessary to provide special storage for these emulsion on these machines. Various solutions have already been proposed by the applicant in this regard. In a particular solution in particular, the emulsion tank is mounted on jacks, above the paver control cabin. During spreading, the tank is held in height by the jacks and, for transporting the paver, the tank is brought closer to the chassis.

La demanderesse propose par la présente invention une solution de stockage nouvelle, notamment en disposant le réservoir d'émulsion au niveau de la trémie de réception des enrobés bitumineux. Une telle solution présente en particulier l'avantage de ne poser aucun problème d'équilibrage, puisque la structure du châssis est initialement prévue pour supporter des surcharges ou des charges variables au niveau de ladite trémie.The applicant proposes by the present invention a new storage solution, in particular by placing the emulsion tank at the level of the hopper for receiving bituminous mixes. Such a solution has in particular the advantage of not posing any problem of balancing, since the structure of the chassis is initially intended to support overloads or variable loads at the level of said hopper.

La présente invention a donc pour objet une machine de construction de chaussée du type finisseur, comportant sur un chassis monté sur des moyens de déplacement, des moyens d'épandage d'enrobés bitumineux, une trémie dans laquelle les enrobés bitumineux sont déposés et des moyens de transfert desdits enrobés bitumineux de ladite trémie auxdits moyens d'épandage, ladite machine comportant également au moins un réservoir pour le stockage d'une substance fluide, telle qu'une émulsion d'accrochage ou un fluide bitumineux, et étant caractérisée en ce qu'un tel réservoir est disposé au niveau de la trémie, en étant supporté par la partie du châssis qui supporte ladite trémie.The present invention therefore relates to a paver construction machine of the paver type, comprising on a chassis mounted on displacement means, means for spreading bituminous mixes, a hopper in which the bituminous mixes are deposited and means for transferring said bituminous mixes from said hopper to said spreading means, said machine also comprising at least one reservoir for the storage of a fluid substance, such as a bonding emulsion or a bituminous fluid, and being characterized in that 'such a tank is disposed at the hopper, being supported by the part of the frame which supports said hopper.

Avantageusement, un tel réservoir est disposé au niveau d'une paroi de la trémie.Advantageously, such a reservoir is disposed at a wall of the hopper.

Dans un mode de réalisation préférentiel, la machine est du type de celles dont la trémie est une trémie à fond et à portes latérales pivotantes, lesdites parties comportant chacune un fond et une paroi latérale s'étendant à partir dudit fond, et admettant en par ticulier deux positions, l'une ouverte dans laquelle le fond de la trémie et les fonds des portes sont destinés à recevoir les enrobés bitumineux, l'autre étant une position rabattue dans laquelle la largeur occupée par la trémie correspond sensiblement ou est inférieure à la largeur du châssis, ladite machine étant caractérisée en ce qu'un réservoir pour le stockage d'une substance fluide est disposé au niveau d'une porte pivotante. Un tel réservoir peut notamment être disposé dans une paroi latérale d'une telle porte pivotante. Dans le cas où un tel réservoir est relié par une tuyauterie d'alimentation à un groupe de pompage, ladite tuyauterie peut avantageusement déboucher dans ledit réservoir dans une zone de celui-ci proche de l'axe de pivotement de la porte correspondante. Egalement, une telle machine peut comprendre des supports roulants, latéralement déployables, destinés à supporter les réservoirs en position ouverte des portes de la trémie.In a preferred embodiment, the machine is of the type whose hopper is a hopper with bottom and pivoting side doors, said parts each comprising a bottom and a side wall extending from said bottom, and admitting by ticular two positions, one open in which the bottom of the hopper and the bottom of the doors are intended to receive the bituminous mixes, the other being a folded position in which the width occupied by the hopper corresponds substantially to or is less than the width of the chassis, said machine being characterized in that a reservoir for the storage of a fluid substance is disposed at a pivoting door. Such a tank can in particular be arranged in a side wall of such a pivoting door. In the case where such a tank is connected by a supply pipe to a pumping group, said pipe can advantageously lead into said tank in an area thereof close to the pivot axis of the corresponding door. Also, such a machine can comprise rolling supports, laterally deployable, intended to support the tanks in the open position of the doors of the hopper.

De façon avantageuse encore, une telle machine comprend un dispositif d'épandage d'une émulsion d'accrochage d'enrobés bitumineux sur la surface d'une route, ladite émulsion d'accrochage étant stockée avant épandage dans le ou lesdits réservoirs. Un tel dispositif d'épandage d'une émulsion d'accrochage peut notamment comprendre une rampe d'épandage disposée à l'arrière du châssis par rapport au sens de déplacement de la machine en cours de l'épandage des enrobés.Also advantageously, such a machine comprises a device for spreading a bituminous asphalt bonding emulsion on the surface of a road, said bonding emulsion being stored before spreading in the said tank or tanks. Such a device for spreading a bonding emulsion may in particular comprise a spreading ramp disposed at the rear of the chassis relative to the direction of movement of the machine during the spreading of the mixes.

Egalement, le ou lesdits réservoirs disposés au niveau d'une trémie peuvent être munis d'une protection thermique permettant d'éviter que le fluide contenu dans le ou lesdits réservoirs soit porté à une température trop importante lorsque la trémie contient des enrobés bitumineux chauds. Un réservoir peut également être muni de moyens de réchauffage d'appoint.Also, the said reservoir (s) disposed at the level of a hopper may be provided with thermal protection making it possible to prevent the fluid contained in the said reservoir (s) from being brought to an excessively high temperature when the hopper contains hot bituminous mixes. A tank can also be provided with additional heating means.

La description qui suit d'un mode de réalisation par ticulier de l'invention est purement illustrative et non limitative. Elle doit être lue en regard des dessins annexés, sur lesquels:

  • la figure 1 est une vue de côté d'une machine de construction de chaussée du type finisseur, conforme à un mode de réalisation particulier de l'invention;
  • la figure 2 est une vue de face de la même machine de construction de chaussée.
The following description of a particular embodiment of the invention is purely illustrative and not limiting. It should be read in conjunction with the accompanying drawings, in which:
  • Figure 1 is a side view of a paver construction machine of the finisher type, in accordance with a particular embodiment of the invention;
  • Figure 2 is a front view of the same pavement construction machine.

On voit sur ces figures, que la machine de construction de chaussée qui y a été représentée schématiquement, comprend principalement sur un châssis 1 monté sur des chenilles 2, une cabine de pilotage 3, ainsi qu'une trémie 4 de réception des enrobés bitumineux et des moyens 5 d'épandage desdits enrobés bitumineux. La trémie 4 est disposée à l'avant du finisseur. Des moyens d'épandage 5 sont constitués, de façon classique, par une vis de répartition et sont disposés à l'arrière du finisseur. La partie arrière du finisseur est également munie d'une table 6 de lissage des couches d'enrobés déposés. Entre l'arrière du châssis 1 du finisseur et ladite vis 5 de répartition, est disposée une rampe 7 d'épandage d'une émulsion d'accrochage, qui est par exemple du type de celles qui ont été décrites dans les différentes demandes de brevet français précitées de la demanderesse. Les enrobés bitumineux chauds déposés dans la trémie 4 par la benne d'un camion d'alimentation C roulant devant le finisseur, sont transférés de ladite trémie 4 jusqu'aux moyens 5 d'épandage des enrobés, par l'intermédiaire d'un tapis de transfert (non représenté) disposé sur le châssis 1 entre les chenilles 2 et la cabine 3. Ce tapis de transfert est légèrement surélevé dans sa partie arrière au-dessus de la rampe 7.It can be seen in these figures that the pavement construction machine which has been represented therein diagrammatically comprises mainly on a chassis 1 mounted on tracks 2, a pilot cabin 3, as well as a hopper 4 for receiving bituminous coated materials and means 5 for spreading said bituminous mixes. The hopper 4 is arranged at the front of the finisher. Spreading means 5 are constituted, in a conventional manner, by a distribution screw and are arranged at the rear of the finisher. The rear part of the paver is also provided with a table 6 for smoothing the layers of coated materials deposited. Between the rear of the frame 1 of the finisher and said distribution screw 5, is arranged a ramp 7 for spreading a bonding emulsion, which is for example of the type which have been described in the various patent applications Applicant's aforementioned French. The hot bituminous mixes deposited in the hopper 4 by the bucket of a feed truck C traveling in front of the paver, are transferred from said hopper 4 to the means 5 for spreading the mixes, via a conveyor belt transfer belt (not shown) arranged on the chassis 1 between the tracks 2 and the cabin 3. This transfer belt is slightly raised in its rear part above the ramp 7.

Ainsi qu'on peut le voir plus particulièrement sur la figure 2, la trémie 4 comprend un fond 11 et deux portes latérales pivotantes 8, constituée chacune d'un fond 9 et d'une paroi latérale 10 qui lui est sensiblement perpendiculaire. Chacune des deux portes 8 est ainsi articulée en pivotement sur le fond 11 de la benne 4, au niveau du bord de son fond 9 qui est le plus éloigné de la paroi 10 correspondante. Les axes 12 de pivotement sont des axes longitudinaux disposés au niveau des bords latéraux du fond 11. Lorsque le finisseur fonctionne et réalise l'application d'un revêtement de chaussée, les portes 8 de la trémie 4 sont disposées dans la position ouverte représentée en traits pleins sur la figure. Leurs fonds 9 sont alors dans le prolongement du fond 11 avec lequel ils forment un fond de réception sur lequel le camion C peut venir déposer les enrobés bitumineux chauds. Lors du transport du finisseur, il est nécessaire de rabattre les portes 8, ainsi que cela a été représenté en traits mixtes sur la figure, de façon que le finisseur 1 soit au gabarit routier et que la trémie 4 ne dépasse pas latéralement de part et d'autre du châssis 1. Les portes 8 sont donc pivotées vers l'intérieur de la trémie autour de leur axe 12, ainsi qu'indiqué par les flèches sur la figure, d'un angle d'environ 45°. Dans cette position rabattue des portes 8, la trémie 4 occupe une largeur de route qui correspond sensiblement à celle du châssis 1 et de la cabine 3. Le mouvement de pivotement des portes 8 est commandé par l'intermédiaire de vérins 13 (figure 1), prenant appui sur le châssis 1 et montés articulés à leur autre extrémité, sur la partie extérieure du fond 9 de la porte 8 correspondante.As can be seen more particularly in Figure 2, the hopper 4 comprises a bottom 11 and two pivoting side doors 8, each consisting of a bottom 9 and a side wall 10 which is substantially perpendicular thereto. Each of the two doors 8 is thus pivotally articulated on the bottom 11 of the bucket 4, at the edge of its bottom 9 which is furthest from the corresponding wall 10. The pivot axes 12 are longitudinal axes arranged at the lateral edges of the bottom 11. When the paver is operating and applying a road surface, the doors 8 of the hopper 4 are arranged in the open position shown in solid lines in the figure. Their bottoms 9 are then in the extension of the bottom 11 with which they form a receiving bottom on which the truck C can come to deposit the hot bituminous mixes. When transporting the paver, it is necessary to fold down the doors 8, as shown in dashed lines in the figure, so that the paver 1 is in the road gauge and the hopper 4 does not protrude laterally from side and other side of the chassis 1. The doors 8 are therefore pivoted towards the inside of the hopper about their axis 12, as indicated by the arrows in the figure, by an angle of approximately 45 °. In this folded position of the doors 8, the hopper 4 occupies a road width which corresponds substantially to that of the chassis 1 and the cabin 3. The pivoting movement of the doors 8 is controlled by means of jacks 13 (FIG. 1) , bearing on the frame 1 and mounted articulated at their other end, on the outer part of the bottom 9 of the corresponding door 8.

Les parois 10 latérales des portes 8 sont des réservoirs sensiblement parallélipipédiques de 350 mm d'épaisseur dans lesquelles est stockée l'émulsion d'accrochage. Leur hauteur à partir du fond 9 est telle qu'en position rabattue des portes 8, les extrémités desdites parois 10 les plus éloignées des fonds 9 soient situées juste au niveau de la partie inférieure de la cabine de pilotage 3, de façon à ne pas obstruer le champ de vision du pilote. Ces réservoirs 10 sont reliés par des tuyauteries 14 (figure 2) à un groupe de pompage (non représenté) et à la rampe 7 d'épandage d'émulsion d'accrochage. Ces tuyauteries 14 débouchent dans les réservoirs 10 dans des zones de ceux-ci proches des fonds 9 des portes 8 correspondantes et des axes 12, ce qui permet à ces tuyauteries 14 d'accompagner les mouvements de pivotement desdites portes 8, sans grand débattement. Les cloisons des réservoirs 10 qui délimitent l'intérieur de la trémie 4 sont munies d'une protection thermique de façon que l'émulsion stockée dans lesdits réservoirs 10 ne soit pas portée à des températures trop élevées lorsque la trémie 4 reçoit des enrobés chauds. Egalement, les cloisons desdits réservoirs 10 sont munies d'un système de réchauffage d'appoint, de façon à ce que l'émulsion d'accrochage puisse être stockée dans lesdits réservoirs 10, même avec des températures extérieures froides.The side walls 10 of the doors 8 are substantially parallelepiped tanks 350 mm thick in which the bonding emulsion is stored. Their height from the bottom 9 is such that in the folded position of the doors 8, the ends of said walls 10 furthest from the bottoms 9 are located just at the bottom of the cockpit 3, so as not to obstruct the pilot's field of vision. These tanks 10 are connected by pipes 14 (FIG. 2) to a pumping group (not shown) and to the ramp 7 for spreading bonding emulsion. These pipes 14 open into the tanks 10 in areas thereof close to the bottoms 9 of the corresponding doors 8 and the axes 12, which allows these pipes 14 to accompany the pivoting movements of said doors 8, without much movement. The partitions of the tanks 10 which delimit the interior of the hopper 4 are provided with thermal protection so that the emulsion stored in said tanks 10 is not brought to excessively high temperatures when the hopper 4 receives hot mixes. Also, the partitions of said tanks 10 are provided with an additional heating system, so that the bonding emulsion can be stored in said tanks 10, even with cold outside temperatures.

Les portes pivotantes 8 de la trémie 4 sont munies de supports (non représentés) roulants au sol, portant au moins partiellement les réservoirs 10 en position ouverte de la trémie.The pivoting doors 8 of the hopper 4 are provided with supports (not shown) rolling on the ground, at least partially carrying the tanks 10 in the open position of the hopper.

Les réservoirs secondaires qui viennent d'être décrits dans le cadre du stockage d'une émulsion d'accrochage pourraient bien entendu être utilisés pour le stockage de toute autre substance fluide, notamment pour le stockage de tout fluide bitumineux.The secondary tanks which have just been described in the context of the storage of a bonding emulsion could of course be used for the storage of any other fluid substance, in particular for the storage of any bituminous fluid.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
