Abstract

Device for mechanical, hydraulic and electric coupling of two independent elements, this coupling is carried out instantaneously and automatically, the various functions are controlled remotely either by electric wires, infrared controls, radio controls or the like.

Description

Les brevets précédents déposés par l'inventeur concernaient les accouplements mécaniques de divers équipements de matérieis TP entre-eux et leur interchangeabilité.The previous patents filed by the inventor concerned the mechanical couplings of various TP material equipment between them and their interchangeability.

Lorsque l'outil venant se placer sous la pelle par l'attache rapide ne comporte aucune transmission hydraulique, c'est-à-dire accouplement, il n'y a pas de problème.When the tool coming to be placed under the shovel by the quick coupler does not have any hydraulic transmission, that is to say coupling, there is no problem.

Mais dès que l'outil à mettre sous l'attache rapide comporte des organes hydrauliques, ou électriques, ou les 2 à la fois, il faut absolument faire le raccordement.But as soon as the tool to be put under the quick coupler has hydraulic, or electrical, or both, it is absolutely necessary to make the connection.

C'est-à-dire dans le cas de l'hydraulique, même s'il y a des accouplements rapides type push-pull, le pelleur par exemple est obligé de descendre de son engin, faire l'accouplement manuellement et remonter. Cela rompt le rythme de travail, est une servitude, et dans les cas de pose de tuyaux par exemple, une perte de temps néfaste pour la tenue des terres risquant de s'ébouler.That is to say in the case of hydraulics, even if there are quick couplings push-pull type, the shoveler for example is forced to get off his machine, make the coupling manually and reassemble. This breaks the pace of work, is an easement, and in the case of laying pipes for example, a waste of time harmful to the holding of the land likely to fall.

La présente invention se propose par des moyens simples de faire le raccordement automatiquement à distance, tant hydrauliquement qu'électriquement.The present invention proposes by simple means to make the connection automatically remotely, both hydraulically and electrically.

En effet, I'usage d'électrovannes pour les commandes hydrauliques est devenu d'usage courant. On peut donc par dimentation unique sur un engin d'apport créer des circuits hydrauliques par des distributeurs eux-mêmes commandés par des électrovannes. Alimenter chaque circuit par une tuyauterie correspondante deviendrait d'un encombrement inutilisable. Les électrovannes sont commandées soit par transmission directe par fil, soit par transmission par commandes radio ou infra-rouge. De la sorte il est possible de créer des engins au bout des engins, chacun commandé séparément, mais alimenté sur le même circuit
Une première observation est à flaire. Les accouplements hydrauliques dits push-pull se font sans pression d'huile. Indeed, the use of solenoid valves for hydraulic controls has become common practice. It is therefore possible by single feeding on a feeder to create hydraulic circuits by distributors themselves controlled by solenoid valves. Supplying each circuit with a corresponding piping would become unusable space. The solenoid valves are controlled either by direct transmission by wire, or by transmission by radio or infrared commands. In this way it is possible to create machines at the end of the machines, each ordered separately, but powered on the same circuit
A first observation is to be smelled. The so-called push-pull hydraulic couplings are made without oil pressure.

II est envisageable de mettre un boîtier protecteur sur les connexions possédant un couvercle qui se relève lorsque le vérin (22) est actionné. It is conceivable to put a protective box on the connections having a cover which is raised when the jack (22) is actuated.

La figure 1 montre une attache rapide (1) de pelle avec des accouplements par axes coniques (2) avec des arrivées hydrauliques sans pression P16 et des tuyauteries sans pression R17 de retour respectivement terminés par des push-pull P3 et R4 femelles de préférence ainsi que des connexions électriques E19 et E18 montées de préférence sur des ressorts comme les montrent les figures 5 et suivantes. Elle montre également un guide (9) dont l'usage sera décrit plus loin.Figure 1 shows a quick coupler (1) of shovel with couplings by conical axes (2) with pressurized hydraulic arrivals P16 and non-pressurized return pipes R17 respectively terminated by push-pull P3 and R4 female preferably as well as electrical connections E19 and E18 preferably mounted on springs as shown in Figures 5 and following. It also shows a guide (9) whose use will be described later.

La figure 2 montre un récepteur femelle d'attache rapide (1) comportant les logements (21) pour les cônes (2), ainsi qu'un logement (10) pour le guide (9) et au moins un boîtier (12) avec tuyauterie hydraulique et si nécessaire transmission électrique.FIG. 2 shows a female quick coupler receiver (1) comprising the housings (21) for the cones (2), as well as a housing (10) for the guide (9) and at least one housing (12) with hydraulic piping and, if necessary, electrical transmission.

La figure 3 montre un boîtier (12) portant de manière apparente la partie mâle du pushpull (15) ainsi que les plaquettes de connexion électrique (14).Figure 3 shows a housing (12) apparently carrying the male part of the pushpull (15) and the electrical connection plates (14).

La figure 4 montre un exemple de commande à distance dans laquelle un mini vérin hydraulique ou électrique (22) pousse par son piston (23) sur un organe (24) lui-même appuyé sur les bagues des push-bull (25), tout en étant appuyé sur le châssis de l'ensemble (26).FIG. 4 shows an example of a remote control in which a mini hydraulic or electric jack (22) pushes by its piston (23) on a member (24) itself supported on the rings of the push-bull (25), all by being supported on the frame of the assembly (26).

La planche 2 par ses figures 5 à 10 montre le processus d'emboitement, accouplement et mise en contact.Plate 2 by its figures 5 to 10 shows the process of nesting, coupling and contacting.

La figure 5 montre tous les organes en position neutre.Figure 5 shows all the bodies in neutral position.

La figure 6 : la bague des push-bull (25) par action sur le vérin passe de la position A en
A'.Figure 6: the push-bull ring (25) by action on the cylinder passes from position A in
AT'.

La figure 7 montre l'attache (1) en position de préhension d'un outil (28) par accrochage de l'anneau (27). La butée (9) se dirige vers le logement (10). Figure 7 shows the attachment (1) in the gripping position of a tool (28) by hooking the ring (27). The stop (9) goes towards the housing (10).

Les figures 8 et 9 montrent l'attache (1) se déplaçant par le guide (9) dans le logement (10) sur une distance C C' amenant l'embout mâle (15) dans l'embout femelle (3).Figures 8 and 9 show the clip (1) moving by the guide (9) in the housing (10) over a distance C C 'bringing the male end (15) in the female end (3).

La figure 10 montre l'outil (28) ayant enclenché le connecteur mâle (15) et la bague (3) revenue en position recouvrement (figure 10) par le vérin de commande (22). L'huile passe. Le câblage est fait. Le travail peut commencer.FIG. 10 shows the tool (28) having engaged the male connector (15) and the ring (3) returned to the covering position (FIG. 10) by the control jack (22). The oil passes. The wiring is done. The work can begin.

II va de soi que le montage décrit ne l'est qu'à titre indicatif et que les mêmes mouvements de branchement peuvent être obtenus par tous les moyens techniques connus. It goes without saying that the assembly described is for information only and that the same branching movements can be obtained by all known technical means.

Il est de la sorte possible de superposer un nombre théoriquement illimité d'unités chacune approvisionnée au moins par un plus hydraulique et électrique, chacun d'entre-eux pouvant alimenter des sous ensembles hydrauliques ou électriques.It is thus possible to superimpose a theoretically unlimited number of units each supplied at least by a more hydraulic and electric, each of them being able to supply hydraulic or electric subassemblies.

Si les câbles de commandes électriques deviennent trop encombrants, il est possible de les remplacer par des commandes sans fil, par radio en infra-rouge, et même si le passage électrique par fil n'est plus possible, rien n'interdit de placer une batterie à demeure si les commandes sont courtes et peu consommatrices.If the electrical control cables become too bulky, it is possible to replace them by wireless controls, by radio in infrared, and even if the electrical passage by wire is no longer possible, nothing prohibits placing a battery permanently if the orders are short and low consumption.

Ajoutons encore que la liaison hydraulique se fait sans pression. Or il faut de l'énergie pour défaire et replacer la bague (25). Si l'on coupe l'hydraulique à la source, le vérin (22) sera commandé préférentiellement électriquement. Toutefois, il est possible de faire la même opération hydrauliquement en interposant des composants de coupure de pression en embout (3) pendant l'alimentation du vérin (22). Sur le plan pratique il est également possible d'aménager la commande du vérin (22) de retrait de la bague (25), de telle sorte qu'une commande unique hydraulique par exemple provoque son retrait préalablement à toute action sur les vérins commandant les axes (2), dans un sens ou dans l'autre (sortielentrée). Let us also add that the hydraulic connection is made without pressure. Now it takes energy to undo and replace the ring (25). If the hydraulics are cut at the source, the cylinder (22) will preferably be electrically controlled. However, it is possible to do the same operation hydraulically by interposing pressure cutting components at the end piece (3) during the supply of the jack (22). On a practical level, it is also possible to arrange the control of the jack (22) for removing the ring (25), so that a single hydraulic control, for example, causes its withdrawal before any action on the jacks controlling the axes (2), in one direction or the other (sortielentrée).
