Description

DISPOSITIF DE BLOCAGE D'AU MOINS UNE CHARGE SUR UNE PARTIE DE CHASSIS D'UN MOYEN DE TRANSPORTDEVICE FOR LOCKING AT LEAST ONE LOAD ON A CHASSIS PART OF A TRANSPORT MEANS
L'invention se rattache au secteur technique des moyens de blocage d'une charge sur une partie de châssis d'un moyen de transport ou autre application.The invention relates to the technical sector of the means for blocking a load on a chassis part of a means of transport or other application.
Par exemple, l'invention trouve une application pour assurer le blocage d'une charge embarquée sur différents moyens de transport du type routier, ferroviaire, maritime et aérien. Une application particulièrement visée, qui ne doit toutefois pas être considérée comme limitative, concerne les appareils de manutention à bras montés sur des camions, des semi- remorques, des remorques, ... Le but recherché est d'équilibrer toutes les sollicitations auxquelles sont susceptibles d'être soumises les charges pendant leur transport, notamment sous l'effet de la force centrifuge, accélération, apesanteur et autres... De nombreuses solutions techniques ont été proposées.For example, the invention finds an application for blocking an on-board load on various means of transport of the road, rail, sea and air type. A particularly targeted application, which should not however be considered as limiting, relates to handling equipment with arms mounted on trucks, semi-trailers, trailers, ... The aim is to balance all the stresses which are likely to be subjected to loads during their transport, in particular under the effect of centrifugal force, acceleration, weightlessness and others ... Many technical solutions have been proposed.
On peut citer, par exemple, l'enseignement du brevet US 3,857,504 qui concerne un verrouillage d'une pièce mobile sur le châssis d'un véhicule. Le verrouillage est obtenu par un ensemble de crochet pivotant coopérant avec des agencements spécifiques de la caisse. Le blocage n'est assuré que dans le sens longitudinal. Pour désengager le crochet en vue de libérer la caisse, il est nécessaire d'agir manuellement sur ce dernier. On peut citer également l'enseignement du brevet US 3,667,401 où le système de verrouillage met en œuvre un crochet pivotant en combinaison avec un système de ressort. Cette solution nécessite des aménagements spécifiques de la caisse, ou conteneur, que l'on veut bloquer sur le châssis. Là encore, le déverrouillage s'effectue de manière manuelle. Une solution équivalente ressort de l'enseignement du brevet US 4, 382,735.We can cite, for example, the teaching of US patent 3,857,504 which relates to a locking of a moving part on the chassis of a vehicle. Locking is obtained by a swivel hook assembly cooperating with specific arrangements of the body. The blocking is assured that in the longitudinal direction. To disengage the hook in order to release the box, it is necessary to act manually on the latter. We can also cite the teaching of US Patent 3,667,401 where the locking system implements a pivoting hook in combination with a spring system. This solution requires specific arrangements of the box, or container, which we want to block on the chassis. Again, unlocking is done manually. An equivalent solution emerges from the teaching of US patent 4, 382,735.
Selon une autre solution connue, largement utilisée, le blocage de la charge (caisse, conteneur ou autre) sur le châssis, s'effectue au moyen de doigts de verrouillage latéraux, assujettis à un système de vérins pour déplacer lesdits doigts en position de verrouillage ou de déverrouillage. Là encore, les doigts de verrouillage coopèrent avec des agencements spécifiques de la charge. On observe également que le fonctionnement des doigts de déverrouillage est directement assujetti au vérin, nécessitant des clapets à valves hydrauliques et autres organes de sécurité, pour verrouiller le circuit hydraulique du ou des vérins de commande.According to another known solution, widely used, the blocking of the load (case, container or other) on the chassis is carried out by means of lateral locking fingers, subject to a system of jacks for moving said fingers in the locking position. or unlocking. Again, the locking fingers cooperate with specific arrangements of the load. It is also observed that the operation of the unlocking fingers is directly subject to the jack, requiring valves with hydraulic valves and other safety devices, to lock the hydraulic circuit of the control jack (s).
L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
Le problème que se propose de résoudre l'invention est de permettre une implantation aisée du dispositif de blocage, sans être obligé d'effectuer des découpes et autres agencements de la charge à bloquer, en ayant pour objectif de diminuer les temps de montage et de supprimer les différents organes de sécurité nécessaires au verrouillage, par exemple du circuit hydraulique des vérins de commande, d'obtenir une sécurité de blocage totalement indépendante, y compris en cas, par exemple, de manque d'étanchéité du vérin de commande, et éventuellement de rupture accidentelle des raccords aux canalisations reliés auxdits vérins.The problem which the invention proposes to solve is to allow easy implantation of the blocking device, without being obliged to make cuts and other arrangements of the load to be blocked, having for objective of reducing assembly times and eliminating the various safety devices necessary for locking, for example of the hydraulic circuit of the control cylinders, to obtain a totally independent locking safety, including in the event, for example, of lack of 'tightness of the control cylinder, and possibly accidental rupture of the fittings to the pipes connected to said cylinders.
Un autre problème important que se propose de résoudre l'invention, est d'obtenir un auto-verrouillage.Another important problem which the invention proposes to solve is to obtain self-locking.
Pour résoudre ces problèmes et atteindre ces différents objectifs, il a été conçu et mis au point un dispositif de blocage d'au moins une charge sur une partie de châssis d'un moyen de transport, qui comprend un corps apte à être fixé sur la partie du châssis, ledit corps étant équipé d'une mâchoire articulée de serrage commandée en pivotement par un système de biellettest articulées faisant office de genouillère et assujettie à un organe de commande porté par le corps, pour soumettre ladite mâchoire à un pivotement angulaire depuis une position ouverte jusqu'à une position fermée d'auto-verrouillage avec une partie de la charge, la genouillère étant articulée sur la mâchoire au moyen d'un axe monté dans un palier élastique.To solve these problems and achieve these various objectives, it has been designed and developed a device for locking at least one load on a chassis part of a means of transport, which comprises a body capable of being fixed on the part of the chassis, said body being equipped with an articulated clamping jaw pivotally controlled by a system of articulated rods acting as a toggle joint and subject to a control member carried by the body, in order to subject said jaw to angular pivoting from a open position to a closed position of self-locking with part of the load, the toggle joint being articulated on the jaw by means of a pin mounted in an elastic bearing.
Compte tenu de ces dispositions, il en résulte que le dispositif est auto-verrouillé par l'élasticité du palier et par les forces auxquelles est soumise la charge. Pour résoudre le problème posé d'assurer le pivotement angulaire de la mâchoire, la genouillère est constituée de deux paires de biellettes articulées entre elles au moyen d'un axe transversal, l'une des paires de biellettes étant articulée au corps, tandis que l'autre est articulée sur la mâchoire, les différents axes d'articulation délimitant les trois sommes d'un triangle déformable sous l'effet de Pactionnement de l'organe de commande depuis la position d'ouverture jusqu'à la position d'auto-verrouillage de ladite mâchoire. Pour résoudre le problème posé de permettre, à volonté, soit la libération de la charge, soit son auto-verrouillage, il apparaît qu'en position d'ouverture de la mâchoire, l'axe d'articulation et d'accouplement entre elles des deux paires de biellettes, est disposé, en-dessous d'une ligne reliant les deux axes d'articulation desdites paires de biellettes sur le corps , ©t la mâchoire, ledit axe d'articulation et d'accouplement, sous l'effet de l'actionnement de l'organe de commande étant, dans un premier temps, aligné avec les deux autres axes provoquant l'écrasement du palier élastique, puis dans un deuxième temps, passe au-dessus de ladite ligne correspondant à une position d'auto-verrouillage de la mâchoire.Given these provisions, it follows that the device is self-locked by the elasticity of the bearing and by the forces to which the load is subjected. To solve the problem posed of ensuring the angular pivoting of the jaw, the toggle joint consists of two pairs of rods hinged together by means of a transverse axis, one of the pairs of rods being articulated to the body, while the the other is articulated on the jaw, the different articulation axes delimiting the three sums of a deformable triangle under the effect of the actuation of the control member from the open position to the self-position. locking of said jaw. To solve the problem posed of allowing, at will, either the release of the load, or its self-locking, it appears that in the open position of the jaw, the axis of articulation and coupling between them two pairs of rods, is arranged, below a line connecting the two axes of articulation of said pairs of rods on the body, © and the jaw, said axis of articulation and coupling, under the effect of the actuation of the control member being, firstly, aligned with the two other axes causing the crushing of the elastic bearing, then secondly, passes above said line corresponding to a self position - locking of the jaw.
Pour résoudre le problème posé d'assurer le pivotement de la mâchoire sous l'effet d'un organe de commande, l'une des extrémités de l'organe de commande est articulée sur le corps, tandis que son autre extrémité est articulée sur l'axe d'articulation et d'accouplement des paires de biellettes. Selon une réalisation préférée, le corps comprend deux flasques verticaux parallèles entre lesquels sont articulés la mâchoire, la genouillère et les organes de commande, qui peut être un vérin. Pour résoudre le problème posé d'assurer un auto-verrouillage sur et efficace, l'extrémité libre de la mâchoire présente des agencements aptes à prendre appui sur la partie de la charge.To solve the problem posed of ensuring the pivoting of the jaw under the effect of a control member, one of the ends of the control member is articulated on the body, while its other end is articulated on the 'axis of articulation and coupling of the pairs of rods. According to a preferred embodiment, the body comprises two parallel vertical flanges between which the jaw, the toggle joint and the control members are articulated, which can be a jack. To resolve the problem posed of ensuring safe and effective self-locking, the free end of the jaw has arrangements capable of bearing on the part of the load.
Selon une forme de réalisation, la partie de la charge est constituée par un longeron de profil transversal en C, les agencements d'appui de la mâchoire coopérant avec l'aile horizontale inférieure dudit profil.According to one embodiment, the part of the load is constituted by a beam of transverse profile in C, the support arrangements of the jaw cooperating with the lower horizontal wing of said profile.
L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels : - la figure 1 est une vue partielle en perspective d'un exemple d'application, nullement limitatif, du dispositif de blocage selon l'invention ; - la figure 2 est une vue en perspective éclatée des principaux éléments du dispositif de blocage ; - la figure 3 est une vue en perspective correspondant à la figure 2, après assemblage des différents éléments, l'un des flasques du corps n'étant pas représenté pour une meilleure compréhension du dessin ; - la figure 4 est une vue de face du dispositif monté au niveau de la charge à bloquer, selon les deux positions extrêmes de la mâchoire ; - la figure 5 est une vue de côté correspondant à la figure 4 ; - les figures 6, 7 et 8 montrent le principe d'auto-verrouillage selon l'invention.The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is a partial perspective view of an example of application, in no way limiting, of the locking device according to the invention. invention; - Figure 2 is an exploded perspective view of the main elements of the locking device; - Figure 3 is a perspective view corresponding to Figure 2, after assembly of the various elements, one of the flanges of the body not being shown for a better understanding of the drawing; - Figure 4 is a front view of the device mounted at the load to be blocked, according to the two extreme positions of the jaw; - Figure 5 is a side view corresponding to Figure 4; - Figures 6, 7 and 8 show the principle of self-locking according to the invention.
Comme indiqué, l'invention trouve une application particulièrement avantageuse pour assurer le blocage des charges embarquées sur tout type de moyens de transport, notamment sur des camions, des remorques, des semi-remorques, plateaux de wagons de chemin de fer, navires porte- conteneurs et autres, avions-cargos spécialisés dans le transport de fret ou autre structure portante fixe ou mobile.As indicated, the invention finds a particularly advantageous application for ensuring the blocking of loads loaded on all types of means of transport, in particular on trucks, trailers, semi-trailers, flatbed of railway wagons, carrier ships. containers and others, cargo planes specializing in the transport of freight or other fixed or mobile carrying structure.
Par exemple, la charge, non représentée, peut être rendue solidaire d'un châssis (C) qu'il convient de bloquer longi dinalement et/ou transversalement sur une structure portante (S). Dans l'exemple illustré, le châssis (C) présente, notamment, deux longerons (Cl) de section transversale sensiblement en forme de G équerré. Les longerons de la structure portante (S) sont par exemple constitués par des fers profilés (SI).For example, the load, not shown, can be made integral with a frame (C) which should be blocked lengthwise and / or transversely on a bearing structure (S). In the example illustrated, the chassis (C) has, in particular, two longitudinal members (Cl) of cross section substantially in the form of a squared G. The longitudinal members of the supporting structure (S) are for example constituted by profiled bars (SI).
Le dispositif de blocage selon l'invention comprend un corps (1) apte à être fixé sur une partie du châssis de la structure portante, par exemple sur les longerons (SI). Ce corps (1) est, dans l'exemple illustré, constitué de deux fiasques verticaux parallèles (la) et (lb) entre lesquels est montée, avec capacité de pivotement angulaire, une mâchoire articulée de serrage (2) au moyen d'un système de biellettes faisant office de genouillère (G) assujettie à un organe de commande (3). Le genouillère est constituée de deux paires de biellettes (4) et (5) articulées entre elles au moyen d'un axe transversal (6). La paire de biellettes (5) est articulée au corps (1) par l'intermédiaire d'un axe transversal (7) monté entre les deux flasques (la) et (lb). L'autre paire de biellettes (4) est articulée entre deux flasques (2a) et (2b) que présente la mâchoire au moyen d'un axe transversal (8) monté dans un palier élastique (9) lui-même monté à l'extrémité inférieure des deux flasques (2a) et (2b) de la mâchoire (2). La mâchoire (2) est elle-même articulée entre les deux flasques (la) et (lb) du corps (1) au moyen d'un axe transversal (10).The locking device according to the invention comprises a body (1) able to be fixed on a part of the chassis of the supporting structure, for example on the side members (SI). This body (1) is, in the example illustrated, consisting of two parallel vertical flasks (la) and (lb) between which is mounted, with angular pivoting capacity, an articulated clamping jaw (2) by means of a system of rods acting as a toggle joint (G) secured to a control member (3). The toggle joint consists of two pairs of links (4) and (5) articulated together by means of a transverse axis (6). The pair of rods (5) is articulated to the body (1) by means of a transverse axis (7) mounted between the two flanges (la) and (lb). The other pair of rods (4) is articulated between two flanges (2a) and (2b) that the jaw presents by means of a transverse axis (8) mounted in an elastic bearing (9) itself mounted to the lower end of the two flanges (2a) and (2b) of the jaw (2). The jaw (2) is itself articulated between the two flanges (la) and (lb) of the body (1) by means of a transverse axis (10).
L'organe de commande (3) peut, par exemple, être un vérin pneumatique, hydraulique ou autre. L'extrémité libre du fût (3a) est articulée par des agencements (11), à l'extrémité inférieure des deux flasques (la) et (lb) du corps (1). L'extrémité libre de la tige (3b) du vérin est agencée en (3c) pour être accouplée avec capacité d'articulation sur l'axe de liaison (6) des deux paires de biellettes (4) et (5).The control member (3) can, for example, be a pneumatic, hydraulic or other cylinder. The free end of the barrel (3a) is articulated by arrangements (11), at the lower end of the two flanges (la) and (lb) of the body (1). The free end of the rod (3b) of the jack is arranged in (3c) to be coupled with articulation capacity on the connecting axis (6) of the two pairs of rods (4) and (5).
D'une manière importante, les différents axes d'articulation (6, 7, 8) délimitent les trois sommets d'un triangle déformable, sous l'effet de l'actionnement de l'organe de commande (3) depuis une position d'ouverture jusqu'à une position d'auto-verrouillage de ladite mâchoire, sur la partie correspondante de la charge, par exemple sur le longeron (Cl) du châssis. On renvoie notamment aux figures 6, 7 et 8. En position d'ouverture de la mâchoire (figure 6), l'axe d'accouplement et d'articulation entre elles des paires de biellettes (4) et (5), est disposé au-dessous d'une ligne (L) reliant les deux axes d'articulation (7) et (8). Dans cette position, la tige (3b) du vérin (3) est rentrée, la mâchoire (2) est totalement écartée du longeron (Cl). Sous l'effet de la commande du vérin (3), sa tige (3b) est déployée provoquant, par le système de genouillère (G), le basculement de la mâchoire (2) en position de blocage sur le longeron (Cl). Le verrouillage est assuré lorsque les trois axes (7, 6 et 8) sont alignés (figure 7) provoquant, d'une manière concomitante, une compression du palier élastique (9).Importantly, the different articulation axes (6, 7, 8) delimit the three vertices of a deformable triangle, under the effect of the actuation of the control member (3) from a position d opening to a self-locking position of said jaw, on the corresponding part of the load, for example on the side member (Cl) of the chassis. Reference is made in particular to FIGS. 6, 7 and 8. In the open position of the jaw (FIG. 6), the coupling and articulation axis between them pairs of rods (4) and (5), is arranged below a line (L) connecting the two axes of articulation (7) and (8). In this position, the rod (3b) of the jack (3) is retracted, the jaw (2) is completely spaced from the spar (Cl). Under the effect of the actuator of the jack (3), its rod (3b) is deployed causing, by the toggle system (G), the tilting of the jaw (2) in the locking position on the spar (Cl). Locking is ensured when the three axes (7, 6 and 8) are aligned (Figure 7) causing, concomitantly, compression of the elastic bearing (9).
Après cette position d'alignement, sous l'effet de la commande du vérin (3), l'axe d'articulation et d'accouplement passe au-dessus de la ligne (L), provoquant l'auto-verrouillage de la mâchoire et le relâchement du palier élastique (figure 8). A titre indicatif nullement limitatif, dans cette position d'auto-verrouillage, l'angle (α)formé par les axes (7, 6, 8) est de l'ordre de 176° et plus généralement inférieur à 180°.After this alignment position, under the effect of the actuator of the jack (3), the articulation and coupling axis passes over the line (L), causing the self-locking of the jaw and the release of the elastic bearing (Figure 8). By way of non-limiting indication, in this self-locking position, the angle (α) formed by the axes (7, 6, 8) is of the order of 176 ° and more generally less than 180 °.
A noter que l'extrémité libre de la mâchoire (2) peut présenter des agencements (12) aptes à prendre appui sur une partie de la charge, par exemple sur l'aile inférieur du longeron (Cl).Note that the free end of the jaw (2) may have arrangements (12) capable of bearing on part of the load, for example on the lower wing of the spar (Cl).
Bien évidemment, plusieurs dispositifs de blocage, conformes aux caractéristiques de l'invention, peuvent équiper la structure portante, pour assurer un blocage transversal et/ou longitudinal de la charge. Compte tenu de ces dispositions, il en résulte que le dispositif est auto-verrouillé, d'une part par l'élasticité du ou des paliers (9) et, d'autre part, par les forces auxquelles est soumise la charge, et qui tendent à augmenter la hauteur du triangle inversé, qui ne peut toutefois se déformer étant donné que la tige du vérin est en butée haute.Obviously, several blocking devices, in accordance with the characteristics of the invention, can be fitted to the bearing structure, to ensure transverse and / or longitudinal blocking of the load. In view of these provisions, it follows that the device is self-locked, on the one hand by the elasticity of the bearing or bearings (9) and, on the other hand, by the forces to which the load is subjected, and which tend to increase the height of the inverted triangle, which however can not deform since the cylinder rod is in high stop.
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle : L'auto-verrouillage mécanique obtenu permettant de supprimer les clapets à flux hydraulique et subsidiairement tout organe de sécurité indispensable pour verrouiller le circuit hydraulique du ou des vérins de télécommande par exemple ; La sécurité du blocage qui est indépendante des éventuels problèmes de vérin (manque d'étanchéité, rupture accidentelle des canalisations, .».«.-;) ; »v-Λ Le gain de poids obtenu ; L'implantation aisée sans être obligé d'effectuer des découpes et autres agencements sur la structure portante du moyen de transport ; La réduction des temps de montage. The advantages emerge clearly from the description, in particular it underlines and is recalled: The mechanical self-locking obtained making it possible to remove the valves with hydraulic flow and, in the alternative, any essential safety member for locking the hydraulic circuit of the remote control actuator (s) by example; Blocking security which is independent of any cylinder problems (lack of tightness, accidental break in pipes,. ”.“ .-;); »V- Λ The weight gain obtained; Easy installation without being obliged to make cuts and other arrangements on the supporting structure of the means of transport; Reduction of assembly times.
