Description

ACCESSOIRE DE VÉHICULE DE TRANSPORT DU GENRE TOUPIE A BÉTON, EN FORME DE REMORQUE MUNIE D'UN ÉQUIPEMENT DE CONVOYAGE DU BÉTONTRANSPORT VEHICLE ACCESSORY OF THE CONCRETE SPINDLE TYPE, IN THE FORM OF A TRAILER PROVIDED WITH CONCRETE CONVEYING EQUIPMENT
La présente invention concerne un accessoire de véhicule de transport du genre toupie à béton, en forme de remorque munie d'un équipement de convoyage du béton.The present invention relates to a transport vehicle accessory of the concrete mixer type, in the form of a trailer provided with concrete conveying equipment.
Pour certains types de véhicules comme des véhicules chargés de produits divers, béton ou autre, il peut être intéressant d'y associer un équipement facilitant le déchargement. Mais cet équipement, lorsqu'il est installé à demeure sur le véhicule, constitue une charge supplémentaire et, bien souvent, ses capacités sont limitées du fait même de son installation à demeure sur ie véhicule.For certain types of vehicles such as vehicles loaded with various products, concrete or other, it may be advantageous to associate therewith equipment facilitating unloading. However, this equipment, when it is permanently installed on the vehicle, constitutes an additional load and, very often, its capacities are limited by the very fact of its permanent installation on the vehicle.
La présente invention propose un accessoire en forme de remorque qui peut être associé à un véhicule du genre toupie à béton par exemple, laquelle remorque comporte des moyens appropriés comme un tapis transporteur pour délivrer le béton à volonté partout où nécessaire.The present invention provides an accessory in the form of a trailer which can be associated with a vehicle of the concrete mixer type for example, which trailer has suitable means such as a conveyor belt for delivering the concrete at will wherever necessary.
Selon l'invention, cet accessoire comprend des moyens d'assujettissement du châssis de la remorque au châssis du véhicule tracteur de façon à associer la stabilité de la remorque à celle du véhicule tracteur et en particulier supprimer les risques de basculement autour de l'axe de roulis du véhicule et de la remorque, lesquels moyens sont mis en œuvre par la flèche de la remorque, laquelle flèche comporte, de façon intrinsèque, des moyens qui permettent de faire varier sa longueur entre une première longueur qui correspond au déploiement normal de la flèche dans son rôle normal de support et de traction, et une deuxième longueur, plus courte que la première, et pour laquelle le châssis de la remorque est maintenu solidarisé et immobilisé sur le châssis du véhicule tracteur.According to the invention, this accessory comprises means for securing the chassis of the trailer to the chassis of the tractor vehicle so as to associate the stability of the trailer with that of the tractor vehicle and in particular eliminate the risks of tilting around the axis. roll of the vehicle and the trailer, which means are implemented by the trailer arrow, which arrow comprises, intrinsically, means which make it possible to vary its length between a first length which corresponds to the normal deployment of the boom in its normal role of support and traction, and a second length, shorter than the first, and for which the chassis of the trailer is kept secured and immobilized on the chassis of the towing vehicle.
Ces moyens permettent d'associer à volonté à un véhicule, une remorque munie d'équipements appropriés, en fonction des besoins. Ainsi, lorsque le véhicule du genre toupie, doit faire plusieurs livraisons sur un même chantier, il peut à l'occasion de son premier déplacement, amener la remorque qui facilitera son déchargement et ensuite laisser ladite remorque in situ pour les déchargements suivants, ne reprenant cette dernière qu'à l'occasion du dernier voyage.These means make it possible to associate at will with a vehicle, a trailer provided with appropriate equipment, as required. Thus, when the vehicle of the router type, must make several deliveries on the same site, it can on the occasion of its first movement, bring the trailer which will facilitate its unloading and then leave said trailer in situ for following unloading, only taking it at the occasion of the last trip.
Les moyens d'assujettissement de la remorque au véhicule tracteur sont particulièrement simples et faciles à mettre en œuvre. Ils sont mis en œuvre au moyen de la flèche qui est par exemple une flèche télescopique manoeuvree au moyen d'un vérin hydraulique. Toujours selon l'invention, les moyens d'assujettissement se présentent sous la forme d'organes de centrage ou d'emboîtements mâles-femelles aménagés pour les uns sur l'arrière du châssis du véhicule et pour les autres sur l'avant de la remorque. Ces différents organes sont au moins au nombre de deux, ou trois et, de préférence, sont constitués d'une paire d'ancrages disposés transversalement de part et d'autre de l'axe longitudinal de traction, lesquels ancrages consistent d'une part, en des plaques munies d'une échancrure en Vé et disposées par exemple à l'arrière du châssis du véhicule tracteur, ledit Vé étant ouvert vers la remorque et, d'autre part, aménagés sur ladite remorque pour pénétrer dans lesdites échancrures, en des axes horizontaux disposés de chaque côté sur l'avant du bâti de ladite remorque.The means of securing the trailer to the towing vehicle are particularly simple and easy to implement. They are implemented by means of the boom which is for example a telescopic boom maneuvered by means of a hydraulic cylinder. Still according to the invention, the securing means are in the form of centering members or male-female sockets arranged for some on the rear of the chassis of the vehicle and for the others on the front of the trailer. These different members are at least two, or three, and preferably consist of a pair of anchors arranged transversely on either side of the longitudinal axis of traction, which anchors consist on the one hand. , in plates provided with a V-shaped notch and arranged for example at the rear of the chassis of the tractor vehicle, said Vee being open towards the trailer and, on the other hand, arranged on said trailer to penetrate said notches, in horizontal axes disposed on each side on the front of the frame of said trailer.
Selon une autre disposition de l'invention, les différents points de centrage et d'ancrage sont disposés dans des plans horizontaux qui sont placés au-dessus et en-dessous de la flèche télescopique, permettant un assujettissement total de la remorque sur la partie arrière du châssis du véhicule tracteur.According to another arrangement of the invention, the various centering and anchoring points are arranged in horizontal planes which are placed above and below the telescopic boom, allowing complete securing of the trailer on the rear part of the towing vehicle chassis.
Dans des conditions particulières, qui peuvent exiger des manœuvres de la part du véhicule de transport, il peut être intéressant de scinder l'accessoire en deux parties : - une partie qui est susceptible de se fixer et de rester accrochée au châssis du véhicule de transport, et - une partie de l'accessoire qui sert essentiellement au portage et peut être abandonnée de façon temporaire pour limiter le poids de la partie fixée au châssis dudit véhicule.In special conditions, which may require maneuvers on the part of the transport vehicle, it may be advantageous to split the accessory into two parts: - a part which is likely to be fixed and to remain attached to the chassis of the transport vehicle , and - a part of the accessory which is essentially used for carrying and can be temporarily abandoned to limit the weight of the part fixed to the chassis of said vehicle.
L'invention propose donc un châssis, pour la remorque accessoire, constitué de deux parties dissociables : - un bâti support comportant les moyens d'attelage et d'assujettissement au véhicule tracteur ainsi que le berceau qui comporte les moyens de déchargement, convoyeur ou autre, - un bâti de roulage muni de roues et de moyens qui permettent son ancrage de façon amovible, sur ledit bâti support.The invention therefore provides a chassis for the accessory trailer, consisting of two separable parts: - a support frame comprising the means of coupling and securing to the towing vehicle as well as the cradle which comprises the unloading means, conveyor or other , - a rolling frame provided with wheels and means which allow its anchoring in a removable manner, on said support frame.
Toujours selon l'invention, le bâti de roulage est en forme de U, comportant l'essieu au niveau du fond du U et une roue jockey disposée par exemple à l'avant sur l'une des branches de ce U.Still according to the invention, the rolling frame is U-shaped, comprising the axle at the bottom of the U and a jockey wheel disposed for example at the front on one of the branches of this U.
Selon une autre disposition de l'invention, le bâti de roulage comporte des bras qui s'étendent à l'arrière de l'essieu, lesquels bras coopèrent avec des moyens appropriés du genre bielle, pour soutenir les moyens de déchargement, en particulier lorsqu'il s'agit d'un dispositif convoyeur. Selon une autre disposition de l'invention, les moyens d'ancrage du bâti de roulage sur le bâti support se présentent sous la forme de systèmes de fermeture comprenant un crochet coopérant avec une chape montée de façon excentrée sur un levier pivotant, ce qui permet de simplifier la mise en place et la réunion des deux bâtis tout en assurant un verrouillage particulièrement efficace desdits bâtis l'un par rapport à l'autre.According to another arrangement of the invention, the rolling frame comprises arms which extend behind the axle, which arms cooperate with suitable means of the connecting rod type, to support the unloading means, in particular when 'It is a conveyor device. According to another arrangement of the invention, the means for anchoring the rolling frame on the support frame are in the form of closure systems comprising a hook cooperating with a yoke mounted eccentrically on a pivoting lever, which allows to simplify the positioning and the joining of the two frames while ensuring a particularly effective locking of said frames with respect to each other.
L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés donnés à titre indicatif, et dans lesquels :The invention will be further detailed with the aid of the following description and of the appended drawings given for information, and in which:

Le véhicule tracteur 1 est représenté partiellement figure 1 faisant apparaître la partie arrière de son châssis 2 et les roues 3. Ce véhicule tracteur peut consister en une toupie à béton par exemple, laquelle toupie n'est pas représentée. Un accessoire en forme de remorque 5 est disposé à l'arrière du véhicule tracteur 1 et cette remorque est représentée figure 1 , dans une position particulière, assujettie et solidarisée à la partie arrière du châssis 2 de son véhicule tracteur.- Figure 7 shows the hooks and yokes for anchoring and locking the rolling frame on the support frame. The tractor vehicle 1 is partially shown in FIG. 1 showing the rear part of its chassis 2 and the wheels 3. This tractor vehicle can consist of a concrete mixer for example, which router is not shown. A trailer-shaped accessory 5 is arranged at the rear of the tractor vehicle 1 and this trailer is shown in FIG. 1, in a particular position, secured and secured to the rear part of the chassis 2 of its tractor vehicle.
Cette remorque 5 comporte un châssis 6 porté par des roues 7. Ce châssis 6 peut par exemple soutenir un tapis transporteur comme représenté, plus loin figure 5, spécialement aménagé pour recevoir le béton qui est déchargé de la toupie, afin de déposer ce béton en un endroit approprié sur un chantier.This trailer 5 comprises a chassis 6 carried by wheels 7. This chassis 6 can for example support a conveyor belt as shown, below in FIG. 5, specially arranged to receive the concrete which is discharged from the router, in order to deposit this concrete in a suitable place on a construction site.
La partie arrière du châssis 2 du véhicule tracteur comporte, latéralement, c'est-à-dire disposées de chaque côté de l'axe longitudinal de traction 9 visible figure 2, des plaques 10 en forme de U ouvert vers la remorque 5. Ces plaques sont fixées par tout moyen approprié, boulonnage ou autre sur le châssis 2 et elles comportent, à chacune des extrémités de leurs branches 11 , des découpes 12 en forme de Vé ouvert vers la remorque 5 qui constituent les moyens d'ancrage et d'assujettissement de la remorque. Les découpes 12 en forme de Vé sont disposées par paires alignées dans des plans horizontaux placés au-dessus et en-dessous du châssis 2 et en particulier, du crochet 13 sur lequel est ancrée la flèche 15 de la remorque 5.The rear part of the chassis 2 of the tractor vehicle comprises, laterally, that is to say arranged on each side of the longitudinal traction axis 9 visible in FIG. 2, plates 10 in the shape of a U open towards the trailer 5. These plates are fixed by any appropriate means, bolting or the like to the chassis 2 and they comprise, at each end of their branches 11, cutouts 12 in the form of a Vee open towards the trailer 5 which constitute the anchoring and securing the trailer. The V-shaped cutouts 12 are arranged in pairs aligned in horizontal planes placed above and below the chassis 2 and in particular of the hook 13 on which the boom 15 of the trailer 5 is anchored.
La remorque 5 comporte une flèche centrale 15 détaillée plus loin et, latéralement, de chaque côté de ladite flèche, des axes 16 horizontaux qui coopèrent avec les échancrures 12 des plaques 10 et en particulier avec le fond de ces échancrures. Ces axes 16 sont solidaires du châssis 6 de la remorque 5, disposés en avant de ce châssis ; ils sont disposés sur des bras longitudinaux 17 qui sont, pour certains, ceux du bas, directement solidaires de la partie avant du châssis 6, et pour ceux situés au-dessus de la flèche 15, solidaires dudit châssis 6 par l'intermédiaire d'une structure 19 qui s'étend verticalement à partir dudit châssis de la remorque. Cette structure 19 forme une sorte de tableau à l'avant de la remorque. La remorque 5 est assujettie au véhicule tracteur 1 par les axes 16 qui s'emboîtent et coopèrent avec les échancrures 12. Cet assujettissement par quatre points disposés selon un rectangle est obtenu et maintenu au moyen de la flèche 15. Les axes 16 et les échancrures 12 constituent les organes de centrage et d'emboîtement mâle-femelle, qui permettent de positionner et de solidariser la remorque au châssis du véhicule tracteur. Lorsqu'elle est solidarisée de cette façon, la remorque bénéficie de la stabilité du véhicule et fait corps avec ce dernier. La flèche 15 qui apparaît en position rétractée figures 1 et 2, est constituée d'un anneau 21 qui coopère avec le crochet 13 du véhicule tracteur, lequel anneau est disposé à l'extrémité de la tige d'un vérin télescopique 22. Le corps du vérin 22 est solidaire du châssis 6 de la remorque 5, fixé sur la structure 19 par exemple. Le vérin 22 peut comporter entre sa partie fixe solidaire du châssis 6 de la remorque et son anneau 21 , des bielles 23 et 24, disposées en forme de ciseaux 25 qui permettent de maintenir constante la position dudit anneau 21 , par exemple dans un plan horizontal.The trailer 5 has a central arrow 15 detailed below and, laterally, on each side of said arrow, horizontal axes 16 which cooperate with the notches 12 of the plates 10 and in particular with the bottom of these notches. These axes 16 are integral with the chassis 6 of the trailer 5, arranged in front of this chassis; they are arranged on longitudinal arms 17 which are, for some, those at the bottom, directly integral with the front part of the chassis 6, and for those located above the boom 15, integral with said chassis 6 by means of a structure 19 which extends vertically from said chassis of the trailer. This structure 19 forms a sort of table at the front of the trailer. The trailer 5 is secured to the towing vehicle 1 by the pins 16 which interlock and cooperate with the notches 12. This securing by four points arranged in a rectangle is obtained and maintained by means of the arrow 15. The pins 16 and the notches 12 constitute the centering and male-female nesting members, which make it possible to position and secure the trailer to the chassis of the towing vehicle. When secured in this way, the trailer benefits from the stability of the vehicle and becomes one with it. The arrow 15 which appears in the retracted position in Figures 1 and 2, consists of a ring 21 which cooperates with the hook 13 of the towing vehicle, which ring is disposed at the end of the rod of a telescopic jack 22. The body the cylinder 22 is integral with the chassis 6 of the trailer 5, fixed to the structure 19 for example. The jack 22 may comprise between its fixed part integral with the chassis 6 of the trailer and its ring 21, connecting rods 23 and 24, arranged in the form of scissors 25 which make it possible to maintain the position of said ring 21 constant, for example in a horizontal plane .
La figure 3 représente la remorque dans sa position normale pour être tractée par le véhicule 1. La flèche 15 est totalement déployée. Cette flèche peut s'étendre entre une première longueur qui correspond à celle représentée figure 3 et pour laquelle la remorque 5 est attelée au véhicule tracteur 1 pour être déplacée en étant maintenue à distance du véhicule tracteur, et une seconde longueur nettement plus courte que la première, qui correspond à celle représentée figures 1 et 2 pour laquelle le châssis de la remorque 5 est assujetti au châssis 2 du véhicule tracteur 1 , par le biais des moyens d'ancrage constitués par les échancrures 12 et les axes 16.Figure 3 shows the trailer in its normal position to be towed by the vehicle 1. The boom 15 is fully deployed. This arrow can extend between a first length which corresponds to that shown in Figure 3 and for which the trailer 5 is coupled to the towing vehicle 1 to be moved while being kept away from the towing vehicle, and a second length significantly shorter than the first, which corresponds to that shown in FIGS. 1 and 2 for which the chassis of the trailer 5 is secured to the chassis 2 of the towing vehicle 1, by means of the anchoring means constituted by the notches 12 and the pins 16.
On retrouve, figure 3, les plaques latérales 10 disposées de part et d'autre du châssis 2 du véhicule tracteur, lesquelles plaques permettent de guider et de maintenir les axes 16 disposés à l'avant du châssis de la remorque On retrouve aussi la flèche 15 qui comprend le vérin télescopique 22 et les bielles 23 et 24 formant les ciseaux 25 disposés de part et d'autre du vérin pour maintenir l'orientation de l'anneau 21 qui sert à atteler la remorque sur le crochet 13 du véhicule tracteur. La figure 4 représente une variante de réalisation de la flèche 15, constituée d'une poutre 32 télescopique de section carrée par exemple, renfermant un vérin 33. Cette poutre est fixée sur l'avant du châssis 6 de la remorque 5.We find, Figure 3, the side plates 10 arranged on either side of the chassis 2 of the tractor vehicle, which plates are used to guide and maintain the axes 16 disposed at the front of the chassis of the trailer We also find the arrow 15 which includes the telescopic jack 22 and the connecting rods 23 and 24 forming the scissors 25 arranged on either side of the jack to maintain the orientation of the ring 21 which is used to couple the trailer on the hook 13 of the towing vehicle. FIG. 4 shows an alternative embodiment of the boom 15, consisting of a telescopic beam 32 of square section for example, containing a jack 33. This beam is fixed to the front of the chassis 6 of the trailer 5.
Le vérin 22 ou 33 est manipulé soit directement à partir d'une centrale hydraulique non représentée, disposée sur la remorque, soit à partir du véhicule tracteur, au moyen de flexibles connectés sur l'alimentation hydraulique propre audit véhicule.The jack 22 or 33 is manipulated either directly from a hydraulic unit (not shown), arranged on the trailer, or from the towing vehicle, by means of hoses connected to the hydraulic supply proper to said vehicle.
Ce vérin 22 ou 33 est utilisé soit complètement déployé lorsqu'il sert de flèche, soit rétracté lorsqu'il sert à maintenir le châssis 6 dans sa position ancrée à l'arrière du véhicule 1.This jack 22 or 33 is used either fully deployed when it serves as an arrow, or retracted when it serves to maintain the chassis 6 in its anchored position at the rear of the vehicle 1.
La figure 5 montre sous forme d'un schéma fonctionnel, la partie arrière du châssis 2 du véhicule avec le crochet 13 et les Vé d'ancrage 12. La remorque 5 comprend un châssis qui est constitué d'un bâti de roulage 61 muni des roues 7 et d'un bâti support 62 qui comporte l'ensemble des moyens lui permettant d'être assujetti à l'arrière du véhicule. Ainsi on retrouve les axes 16 qui coopèrent avec les Vé d'ancrage 12 du véhicule. Les axes 16 sont disposées comme précédemment de part et d'autre de la flèche 15 qui est schématisée sous la forme d'un vérin télescopique.FIG. 5 shows in the form of a functional diagram, the rear part of the chassis 2 of the vehicle with the hook 13 and the anchor V's 12. The trailer 5 comprises a chassis which consists of a rolling frame 61 provided with the wheels 7 and a support frame 62 which includes all of the means enabling it to be secured to the rear of the vehicle. Thus we find the axes 16 which cooperate with the anchoring Ves 12 of the vehicle. The axes 16 are arranged as above on either side of the arrow 15 which is shown schematically in the form of a telescopic cylinder.
On remarque que le bâti support 62 soutient un dispositif de déchargement 50 en forme de tapis convoyeur par exemple monté sur tourelle 51, laquelle tourelle est montée sur un berceau 52 qui fait partie du bâti support 62.It is noted that the support frame 62 supports an unloading device 50 in the form of a conveyor belt, for example mounted on a turret 51, which turret is mounted on a cradle 52 which is part of the support frame 62.
Le bâti de roulage 61 se présente sous la forme d'un U disposé devant l'essieu 63. Les branches latérales 64 et 65 comportent à leur extrémité des aménagements 66 en forme d'axes par exemple qui coopèrent avec des aménagements de forme complémentaire 67 situés sur le bâti support 62, à sa partie avant. De même, la traverse 69 constituant le fond du U, disposé devant l'essieu 63, comporte un aménagement en forme d'axe 70, situé par exemple dans sa partie centrale, coopérant avec une chape 71 située à la partie arrière du bâti support 62. Le bâti de roulage 61 peut également s'étendre à l'arrière de l'essieu 63 formant une sorte de cadre 73 à partir duquel une bielle 74 représentée partiellement figure 5, peut servir d'organe de soutènement du dispositif convoyeur 50. Cette bielle 74 est par exemple articulée sur un axe 75 disposé au centre de la partie arrière du cadre 73. On remarque que le bâti de roulage 61 comporte à sa partie avant, associée par exemple à la branche 65 du U, une roue jockey 76 qui permet de stabiliser ledit bâti et de faciliter son déplacement et son guidage sur le sol.The rolling frame 61 is in the form of a U arranged in front of the axle 63. The lateral branches 64 and 65 have at their end arrangements 66 in the form of axes for example which cooperate with arrangements of complementary shape 67 located on the support frame 62, at its front part. Similarly, the cross member 69 constituting the bottom of the U, disposed in front of the axle 63, has an arrangement in the form of an axis 70, located for example in its central part, cooperating with a yoke 71 located at the rear part of the support frame 62. The rolling frame 61 can also extend behind the axle 63 forming a sort of frame 73 from which a connecting rod 74 partially shown in FIG. 5 can serve as a support member for the conveyor device 50. This connecting rod 74 is for example articulated on an axis 75 disposed in the center of the rear part of the frame 73. It is noted that the rolling frame 61 has at its front part, associated for example with the branch 65 of the U, a jockey wheel 76 which stabilizes said frame and facilitates its movement and its guidance on the ground.
La fixation du bâti de roulage 61 sur le bâti support 62 après emboîtement et centrage des axes 66, 70 dans les chapes 67, 71 respectivement, peut être réalisée au moyen de systèmes de fermeture et de verrouillage du type de celui qui est représenté figure 7. Ce système de verrouillage comprend un crochet 80 fixé par exemple sur le bâti support 62 et un levier 81 articulé sur un pivot 82 solidaire du bâti de roulage 61 , lequel levier comporte sur sa longueur, à proximité du pivot 82, une chape 83 qui coopère avec le crochet 80. Le verrouillage s'effectue par un mouvement de basculement du levier 81 , lequel basculement, par un mouvement d'excentrique de la chape 83, resserre le bâti de roulage 61 sur le bâti support 62 et maintient automatiquement les deux bâtis verrouillés dans cette position, en plaçant le levier 81 en fin de course, sur une butée 84. The fixing of the rolling frame 61 on the support frame 62 after interlocking and centering of the axes 66, 70 in the yokes 67, 71 respectively, can be achieved by means of closing and locking systems of the type of that shown in FIG. 7 This locking system comprises a hook 80 fixed for example on the support frame 62 and a lever 81 articulated on a pivot 82 secured to the rolling frame 61, which lever comprises over its length, near the pivot 82, a yoke 83 which cooperates with the hook 80. The locking is effected by a tilting movement of the lever 81, which tilting, by an eccentric movement of the yoke 83, tightens the rolling frame 61 on the support frame 62 and automatically maintains the two frames locked in this position, by placing the lever 81 at the end of the stroke, on a stop 84.
