Abstract
Description
La présente invention concerne un système d'ouverture, de fermeture et de verrouillage d'une porte ou ridelle hydraulique rabattable, sur benne basculante ou plateau, permettant entre autres le chargement ou le déchargement fractionné du contenu. The present invention relates to a system for opening, closing and locking a folding hydraulic door or drop side, on a tilting skip or tray, allowing, inter alia, the loading or fractional unloading of the content.
En général deux systèmes différents sont utilisés pour tenter d'assurer ce fonctionnement. In general two different systems are used to try to ensure this operation.
Le premier consiste à différer le mouvement d'ouverture suite au déverrouillage par l'intermédiaire d'une tringlerie et d'un trou oblong. The first consists in delaying the opening movement following unlocking by means of a linkage and an oblong hole.
Simple de conception, ce système présente quelques inconvénients notoires à savoir : ouverture brutale et non contrôlable de la ridelle dans les premiers quarante degrés minimum d'où usure accrue des composants mécaniques et inconfort d'utilisation augmenté d'un manque de sécurité de maintien de la dite ridelle en cas de mauvais verrouillage. Simple in design, this system has some notable drawbacks, namely: abrupt and uncontrollable opening of the side panel in the first forty degrees minimum, hence increased wear of the mechanical components and discomfort of use increased by a lack of security in maintaining the said drop side in the event of poor locking.
Le second consiste à séquencer les divers mouvements à l'aide d'un circuit hydraulique complexe et par adjonction de vérins supplémentaires de verrouillage. The second is to sequence the various movements using a complex hydraulic circuit and by adding additional locking cylinders.
Ce système résolvant en partie les problèmes du premier cité présente une mise en oeuvre laborieuse, de plus en cas de charge importante sur la ridelle il autorise inopinément la fonction verrouillage avant la fermeture de la ridelle, le nombre important de pièces nécessaires à son fonctionnement augmente également les risques d'anomalies. This system partially solving the problems of the first city has a laborious implementation, moreover in the event of a heavy load on the side panel it unexpectedly authorizes the locking function before the side panel closes, the large number of parts necessary for its operation increases also the risks of anomalies.
L'invention a pour but de répondre favorablement et en toute sécurité aux exigences techniques croissantes imposées par l'évolution de l'utilisation très polyvalente de ce type de matériel en puissance, souplesse et précision. The invention aims to respond favorably and safely to the increasing technical requirements imposed by the evolution of the very versatile use of this type of equipment in power, flexibility and precision.
Sa conception simple et d'un coût peu élevé, résoud la totalité des problèmes énoncés ci-dessus. Its simple and inexpensive design solves all of the above problems.
Le déverrouillage, l'ouverture, la fermeture et le verrouillage de la ridelle hydraulique s'effectue à partir d'une commande unique ; la rapidité du mouvement est modulable suivant la pression exercée sur le levier de commande, le mouvement est parfaitement contrôlable et sans aucun à-coup dans toute sa cinématique utile soit (1600), voire plus si l'espace disponible le permet ; il peut être interrompu instantanément quelque soit sa position par relâchement de la manette de commande, le nombre de vérins, d'un minimum de deux, ainsi que leur section et leur fonction sera déterminé en fonction des performances à obtenir. The unlocking, opening, closing and locking of the hydraulic side panel is carried out from a single command; the speed of the movement is adjustable according to the pressure exerted on the control lever, the movement is perfectly controllable and without any jerk in all of its useful kinematics, ie (1600), or even more if the available space allows; it can be interrupted instantly whatever its position by releasing the control handle, the number of cylinders, a minimum of two, as well as their section and their function will be determined according to the performance to be obtained.
L'invention est décrite ci-après à l'aide d'un de ses modes de réalisation, pris à titre illustratif et sans aucun caractère limitatif en se référant aux croquis annexés. The invention is described below using one of its embodiments, taken by way of illustration and without any limiting character, with reference to the accompanying drawings.
Selon l'invention la benne ou le plateau comporte au moins une ridelle hydraulique actionnée par au moins deux vérins agissant séquentiellement en déverrouillage et ouverture par l'intermédiaire d'une valve et simultanément en fermeture et verrouillage, l'ensemble commandé par une manette unique. According to the invention, the bucket or the platform comprises at least one hydraulic drop side actuated by at least two jacks acting sequentially in unlocking and opening via a valve and simultaneously in closing and locking, the assembly controlled by a single lever. .
Dans un mode de réalisation particulier, la vitesse d'exécution du mouvement est uniquement conditionnée par la pression exercée sur la manette de commande et limitée par l'usinage approprié du tiroir du distributeur. Le vérin peut animer plusieurs points de verrouillage, le mouvement peut être interrompu quelque soit sa position et le nombre et la section des vérins assurant chaque fonction seront déterminés par les performances à obtenir. In a particular embodiment, the speed of execution of the movement is only conditioned by the pressure exerted on the control lever and limited by the appropriate machining of the dispenser drawer. The cylinder can animate several locking points, the movement can be interrupted whatever its position and the number and section of the cylinders ensuring each function will be determined by the performance to be obtained.

La figure 6 représente le détail de l'extrémité de l'axe de verrouillage mécanique.FIG. 1 represents a hydraulic schematic diagram according to the invention;
Figure 2 shows the drop side in the closed and locked position viewed from the front
FIG. 3 represents this drop side in the locked closed position seen according to AA
FIG. 4 represents this drop side in the locked closed position seen along BB
FIG. 5 shows this drop side in the open operating position;
Figure 6 shows the detail of the end of the mechanical locking axis.
Comme il ressort des figures, l'extrémité inférieure de la ridelle (1) est montée de façon à pouvoir pivoter autour du plancher (2). As can be seen from the figures, the lower end of the drop side (1) is mounted so that it can pivot around the floor (2).
Par pression sur la manette de commande (3), pneumatique dans l'exemple, le tiroir du distributeur (4), préalablement usiné pour obtenir un débit mini et maxi, s'ouvre et alimente en huile, côté petite section, les vérins (5) et (6) ; à cet instant, seul le vérin (5) réagit et entraine la pièce (8) articulée sur l'axe (9) et la pièce (10) elle-même articulée sur la pièce (8) par l'axe (11) sur lequel est montée la tête du vérin (5), le pied du vérin (5) est également articulé sur l'axe (12), cet ensemble entraîne l'axe (13) qui suit la trajectoire que lui impose le trou oblong (14), l'axe (13) tire sur la tringlerie (15) qui fait pivoter la pièce (16) sur l'axe (24) entraînant le deverrouillage de l'axe (17) et comprimant le ressort (18) sur la pièce (19) ; il est à noter que la tringlerie (15) et (16) pourra faire fonctionner le cas échéant plusieurs points de verrouillage non représentés. By pressing the control lever (3), pneumatic in the example, the distributor slide (4), previously machined to obtain a minimum and maximum flow, opens and supplies oil, on the small section side, the cylinders ( 5) and (6); at this instant, only the jack (5) reacts and drives the part (8) articulated on the axis (9) and the part (10) itself articulated on the part (8) by the axis (11) on which is mounted the cylinder head (5), the cylinder base (5) is also articulated on the axis (12), this assembly drives the axis (13) which follows the path imposed by the oblong hole (14 ), the axis (13) pulls on the linkage (15) which rotates the part (16) on the axis (24) causing the axis (17) to be unlocked and compressing the spring (18) on the part (19); it should be noted that the linkage (15) and (16) can operate, if necessary, several locking points not shown.
Lorsque l'axe (13) atteint l'extrémité inférieure du trou oblong (14) le circuit hydraulique monte en pression, le vérin (6) ne pouvant fonctionner que si la pression du circuit provoque l'ouverture de la valve (7) ou dépasse la valeur à laquelle elle est réglée ; lorsque cette valeur est atteinte la valve (7) s'ouvre et permet le mouvement de descente contrôlée et sans ouverture brutale de la ridelle (1). When the axis (13) reaches the lower end of the oblong hole (14) the hydraulic circuit rises in pressure, the jack (6) being able to operate only if the pressure of the circuit causes the opening of the valve (7) or exceeds the value at which it is set; when this value is reached the valve (7) opens and allows the controlled lowering movement and without abrupt opening of the drop side (1).
En phase de fermeture de la ridelle (1), la valve (7) n'a aucune influence sur le circuit hydraulique, les vérins (5) et (6) fonctionnent alors en harmonie et additionnent leur puissance ; lorsque l'axe (17) vient en contact avec le poteau (20) solidaire du plancher (2), le biseau (21) fait glisser cet axe (17) qui comprime le ressort (18), mouvement autorisé par le trou oblong (22), lorsque l'axe (17) se trouve en face du trou (23) il s'v loge sous l'impulsion du ressort (18) ; la ridelle (1) est alors immobilisée mécaniquement par l'axe (17), et hvdrauliquement par le vérin (6) lui même immobilisé par la valve (7). When the drop side (1) is closing, the valve (7) has no influence on the hydraulic circuit, the jacks (5) and (6) then operate in harmony and add their power; when the axis (17) comes into contact with the post (20) integral with the floor (2), the bevel (21) slides this axis (17) which compresses the spring (18), movement authorized by the oblong hole ( 22), when the axis (17) is opposite the hole (23) it fits under the impulse of the spring (18); the side wall (1) is then immobilized mechanically by the pin (17), and hydraulically by the jack (6) itself immobilized by the valve (7).
Ce système est particulièrement destiné pour le déchargement latéral fractionné d'une benne équipant un véhicule This system is particularly intended for the fractional lateral unloading of a bucket fitted to a vehicle
