Abstract

The position indication equipment is for the sliding plug of a piston-type valve, having a sliding component of non-magnetic material fixed to the plug and supporting one or more permanent magnets . Round the component are non-magnetic supports for a magnetic proximity detector. The proximity generator produces an electrical signal only when the magnet is close to it. Each detector can be a reed-switch, and where the plug has a middle and two end positions there can be two detectors, the magnet being between them in the middle position.

Description

La présente invention est relative à un dispositif d'un type nouveau , pour contrôler l'état d'un distributeur ou d'un commutateur dont l'organe mobile est animé d'un mouvement coulissant. Elle concerne , plus particulièrement , quoique non exclusivement , le cas d'un distributeur hydraulique à tiroir coulissant
On connaît des distributeurs hydrauliques à tiroir coulissant , dont la commande est effectuée par divers procédés ,@ manuellement 9 automatiquement , ou à distance. Le tiroir est alors déplacé de l'une à l'autre des diverses positions qu'il est susceptible d'occuper 9 et qui D chacune , correspondent à une commutation don née sur les circuits.The present invention relates to a device of a new type, for controlling the state of a distributor or a switch whose movable member is driven by a sliding movement. It relates, more particularly, although not exclusively, to the case of a hydraulic distributor with sliding drawer
Hydraulic distributors with a sliding drawer are known, the control of which is effected by various methods, @ manually 9 automatically, or remotely. The drawer is then moved from one to the other of the various positions that it is likely to occupy 9 and which D each, correspond to a switching given born on the circuits.

La présente invention vise à réaliser un dis positif permettant de détecter à chaque instant , Ba posi- tion du tiroir distributeur , en fournissant une information qui caractérise cette position instantanée . The present invention aims to produce a positive device making it possible to detect at all times, Ba position of the dispenser drawer, by providing information which characterizes this instantaneous position.

L'avantage d'un tel dispositif est , non seulement de permettre un affichage illustrant à chaque instant la commutation effectuée , mais également , de fournir une information utilisable par exemple dans une centrale électronique de calcul. On sait que le développement des automatismes @ot de l'octronique permet de dé@lencher automatiquement certains programmes séquentiels , ou bien interdire certains mouvements de la machine lorsque sont réunies des conditions déterminées , etc..L'invention permet de fournir les informations utilisables à chaque instant dans de telles calculatrices d'automatisation . The advantage of such a device is not only to allow a display illustrating at each instant the switching carried out, but also to provide information usable for example in an electronic computing center. We know that the development of automation @ot of electronics makes it possible to automatically start certain sequential programs, or else to prohibit certain movements of the machine when certain conditions are met, etc. The invention makes it possible to provide the usable information at all times in such automation calculators.

A titre d'exemple particulier , et non limitatif , l'invention vise plus particulièrement le cas d'un distributeur hydraulique prévu pour commander les mouvements d'une grue de levage portée par un camion. On sait que pour éviter toute fausse manoeu@re , et supprimer tout risque de renversement du véhicule porteur ,il est nécessaire, de prévoir des automatismes autorisant ou interdisant certains mouvements de la grue de levage , en fo@ction du poids de la charge à manutentionner , du devers du terrain portant le camion , de la longueur r du bras télescopique de la grue , etc...  By way of a particular, and non-limiting example, the invention relates more particularly to the case of a hydraulic distributor provided for controlling the movements of a lifting crane carried by a truck. We know that to avoid any false maneuver, and to eliminate any risk of the carrier vehicle overturning, it is necessary to provide automatic mechanisms authorizing or prohibiting certain movements of the lifting crane, depending on the weight of the load to be handle, the slope of the ground carrying the truck, the length r of the telescopic arm of the crane, etc ...

Un dispositif contrôleur d'état selon l'invention , destiné à équiper le tiroir coulissant d'un organe commutateur ou distributeur , est caractérisé en ce qutil comprend un coulisseau en matériau amagnétique solidaire du tiroir avec lequel il se déplace et portantau moins un aimant permanent , tandis que par ailleurs t autour du coulisseau sont disposés des supports amagnétiques équipés d'au moins un détecteur magnétique de proximité fournissant ou non une impulsion électrique selon que lBai- mans se trouve à proximité ou à distance'0
Suivant une autre caractéristique de l'inven- tion , chaque détecteur de proximité est constitué par une ampoule du type connu sous l'appellation commercial@ " poule REED".A state controller device according to the invention, intended to equip the sliding drawer with a switch or distributor member, is characterized in that it comprises a slide made of non-magnetic material integral with the drawer with which it moves and carrying at least one permanent magnet , while in addition t around the slide are arranged non-magnetic supports equipped with at least one magnetic proximity detector providing or not an electrical impulse depending on whether Baamans is near or at a distance'0
According to another characteristic of the invention, each proximity detector is constituted by a bulb of the type known under the trade name @ "REED hen".

Suivant une autre caractéristique de l'invention, le tiroir du distributeur est un tiroir à trois positions, à savoir une position centrale , et deux positions extrêmes de commutation , tandis que les supports amagnétiques comportent deux détecteurs magnétiques de proximité situés au v@@inage immédiat de l'omplacement occupé par l'aimant permanent , quand le tiroir est à l'une ou l'autre des deux positions extrêmes. Autrement dit , , pour la position cen- trale du tiroir l'aimant permanent se trouve entre les deux détecteurs de proximité . According to another characteristic of the invention, the distributor drawer is a drawer with three positions, namely a central position, and two extreme switching positions, while the non-magnetic supports include two magnetic proximity detectors located at v @@ inage immediate of the replacement occupied by the permanent magnet, when the drawer is in one or the other of the two extreme positions. In other words, for the central position of the drawer, the permanent magnet is between the two proximity switches.

Le dessin annexé , donne à titre d'exemple non limitatif , permettra de mieux comprendre les caractéristi- ques de l'invention. The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention.

Figure t est une vue en coupe longitudinale d'un distributeur hydraulique à tiroir équipé d'un dispositif selon l'invention. Figure t is a longitudinal sectional view of a hydraulic slide valve equipped with a device according to the invention.

Figure 2 est une coupe suivant II - II ( figure 1).  Figure 2 is a section along II - II (Figure 1).

On a représenté sur les dessins un distributour hydraulique dont le corps fixe 1 comporte diverses canalisations susceptibles d'être mises en communication ou au cntraire isoles les unes des autres , suivant la i position occupée par un tiroir commutateur coulissant 2
Dans l'exemple illustré t le distributeur hydraulique est d'un modèle standard à trois positions , à savoir t
- une position centrals illustrée sur la figure 1
- deux positions extrêmes obtenues par déplacement , l'une vers la gauche , l'autre vers la droite , et correspondant chacune à une alimentation des circuits hydrauliques5
Selon l'invention , on prévoit à une extré- mité du tiroir coulissant 2 , une entretoise de raccordement 3 , sur laquelle est fixé un coulisseau 4 , réalisé on un matériau amagnétique . Le coulisseau 4 peut être par exemple en laiton . Un aimant permanont 5 y est encastré .A hydraulic distributor has been shown in the drawings, the fixed body 1 of which comprises various conduits capable of being placed in communication or at the same time isolated from one another, depending on the position occupied by a sliding switch drawer 2
In the example illustrated t the hydraulic distributor is of a standard model with three positions, namely t
- a central position illustrated in Figure 1
- two extreme positions obtained by displacement, one to the left, the other to the right, and each corresponding to a supply to the hydraulic circuits5
According to the invention, a connection spacer 3 is provided at one end of the sliding drawer 2, to which a slide 4 is fixed, made of a non-magnetic material. The slide 4 can for example be made of brass. A permanent magnet 5 is embedded there.

Le oulisseau 4 suit les mouvements du ti- roir 2 , et , pour cela , il coulisse à l'intérieur d'un support fixe 6 , réalisé lui aussi en un matériau amagnétique tel qu'une matière plastique , superpolyamide ou autre. The oulisseau 4 follows the movements of the drawer 2, and, for this, it slides inside a fixed support 6, also made of a non-magnetic material such as a plastic, superpolyamide or other material.

L'@nsemble est recouvert d'un capot amagnétique 7 , réalisé par exemple , en aluminium. The @ nsemble is covered with a non-magnetic cover 7, made for example, of aluminum.

Dans le rilsan du support 6 , sont enacstrés deux détecteurs de proximité magnétiques 8 et 9 , qui peu vent être par exemple du genre connu sons la dénomination commerciale " ampoule REED " . In the rilsan of the support 6, two magnetic proximity detectors 8 and 9 are embedded, which may for example be of the known type under the trade name "REED bulb".

Ces ampoules REED sont reliées à un circuit électronique non représenté 9 qui peut être de tout type connu . These REED bulbs are connected to an electronic circuit (not shown) 9 which can be of any known type.

UNE prise électrique 10 à raccordement amovible permet d'assurer le branchement des ampoules 8 et 9 et leur liaison avec le circuit électronique. An electrical outlet 10 with removable connection makes it possible to connect the bulbs 8 and 9 and link them to the electronic circuit.

Le fonctionnement est le suivant :
Quand le distributeur est en position neutre 9 le tiroir 2 occupe la position centrale illustrée sur la fi gure 1 . Dans ce cas , l'aimant permanent 5 se trouve à éga
el distance entre les deux ampoules 8 et 9 , qui ne fournis- sent aucune impulsion électrique.The operation is as follows:
When the distributor is in neutral position 9 the drawer 2 occupies the central position illustrated in FIG. 1. In this case, the permanent magnet 5 is also
el distance between the two bulbs 8 and 9, which provide no electrical impulse.

Si l'on déplace le tiroir. 2 bvers la droite pour commuter le circuit hydraulique correspondant , l'aimant permanent 5 vient à proximité de l'ampoule 9 qui envoie alors une impulsion vers le circuit électronique de détection. If we move the drawer. 2 to the right to switch the corresponding hydraulic circuit, the permanent magnet 5 comes close to the bulb 9 which then sends a pulse to the electronic detection circuit.

Inversement , si l'on déplace le tiroir 2 à fond vers la gauche 9 pour une autrs position de commuta tira hydraulique ,l'aimant permanent 5 vient à proximité de l'ampoul 8 , et c'est cette derniere qui envoie alors une impul- sion vers le circuit électronique. Conversely, if the drawer 2 is moved all the way to the left 9 for another hydraulic switching position, the permanent magnet 5 comes close to the bulb 8, and it is the latter which then sends an impulse - sion to the electronic circuit.

On voit que la dispositif selon l'invention peut être adapté sur des distributeurs à deux ou trois positions . Il permet d1 informer l'utilisateur que le tiroir 2 a subi un mouvement . It is seen that the device according to the invention can be adapted on distributors with two or three positions. It informs the user that the drawer 2 has undergone a movement.

Dans l'exemple illustré t l'information transmise est interrompue lorsque le tiroir 2 revient à sa position centrale neutre ( par exemple sous l'effet du ressort de rappel 11).  In the example illustrated, the information transmitted is interrupted when the slide 2 returns to its neutral central position (for example under the effect of the return spring 11).
