DISPOSITIF D'ACTIONNEMENT DE LA LISSE D'UNE BARRIERE DEVICE FOR ACTUATING THE BARRIER SMOOTH
L'invention concerne un dispositif d'actionnement de la lisse d'une barrière destinée notamment à équiper les péages d'autoroutes. Plus particulièrement, l'invention concerne un dispositif d'actionnement de la lisse d'une barrière entre deux positions extrêmes dont l'une correspond à la fermeture d'un passage et l'autre correspond à l'ouverture de ce passage.The invention relates to a device for actuating the rail of a barrier intended in particular to equip motorway tolls. More particularly, the invention relates to a device for actuating the rail of a barrier between two extreme positions, one of which corresponds to the closure of a passage and the other of which corresponds to the opening of this passage.
On connaît déjà de nombreux dispositifs d'actionnement de la lisse d'une barrière, lesquels peuvent être classés en deux grandes catégories : ceux utilisant une motorisation électrique et ceux utilisant une motorisation pneumatique.Numerous devices for actuating the barrier boom are already known, which can be classified into two main categories: those using an electric motor and those using a pneumatic motor.
Les dispositifs d'actionnement de la lisse d'une barrière utilisant une motorisation électrique sont actuellement les plus répandus et équipent aujourd'hui la grande majorité des barrières de péages autoroutiers, de parkings ou autres. Le moteur est généralement à courant alternatif (triphasé) et entraîne la lisse à travers un réducteur et un système bielle-manivelle, ou un entraînement par chaîne. Dans ce type de motorisation, on trouve également des dispositifs intégrant des moteurs couples. Les moteurs sont généralement soulagés à la montée par un ou des ressorts. L'état de la technique de ce type de motorisation est illustré notamment par les documents FR-A-2 656 884, FR-A-2 678 298, FR-B-2 661 571, FR-A-2 679 936.The devices for actuating the barrier boom using an electric motor are currently the most widespread and today equip the vast majority of motorway, car park or other barriers. The motor is generally AC (three-phase) and drives the arm through a reduction gear and a rod-crank system, or a chain drive. In this type of motorization, there are also devices incorporating torque motors. The motors are generally relieved when mounted by one or more springs. The state of the art of this type of motorization is illustrated in particular by the documents FR-A-2 656 884, FR-A-2 678 298, FR-B-2 661 571, FR-A-2 679 936.
Ce type de dispositif intégrant une motorisation électrique présente les inconvénients inhérents à ce type de motorisation, à savoir : un nombre important d'éléments mécaniques de transmission engendrant un coût de revient excessif et un coût de maintenance élevé ; la nécessité d'un relayage électromécanique dans la plupart des cas, du fait d'un courant d'appel élevé ; une vitesse de manoeuvre
relativement lente : de 0,8 à 5 secondes par mouvement selon les dispositifs, et de façon générale, une fiabilité moyenne inversement proportionnelle à la vitesse de manoeuvre. Les dispositifs d'actionnement de la lisse d'une barrière intégrant une motorisation pneumatique sont de diffusion beaucoup plus restreinte, et sont surtout employés pour les accès de parkings et n'ont de ce fait pas de contraintes particulières de rapidité. Il s'ensuit que leur motorisation est insuffisante pour une utilisation en milieu autoroutier.This type of device incorporating an electric motor has the drawbacks inherent in this type of motor, namely: a large number of mechanical transmission elements generating an excessive cost price and a high maintenance cost; the need for electromechanical relaying in most cases, due to a high inrush current; maneuvering speed relatively slow: from 0.8 to 5 seconds per movement depending on the device, and in general, average reliability inversely proportional to the operating speed. The devices for actuating the boom of a barrier incorporating a pneumatic motorization are much more restricted, and are mainly used for parking lot access and therefore have no particular speed constraints. It follows that their motorization is insufficient for use in a motorway environment.

Il est également souvent assisté d'un ressort pour la montée.The motorization is ensured by a single pneumatic linear actuator acting on a lever mounted on the drive shaft of the arm. It is also often assisted by a spring for the climb.

Ce type de dispositif d'actionnement intégrant une motorisation pneumatique présente l'inconvénient d'une vitesse de manoeuvre lente et des chocs importants en fin de course de la lisse, dûs à une pression non régulée et un mauvais amortissement engendrant de ce fait une fatigue importante des différents organes constituant le dispositif d'actionnement.This type of actuating device incorporating a pneumatic motor has the disadvantage of a slow operating speed and significant shocks at the end of the boom, due to an unregulated pressure and poor damping, thereby causing fatigue. important of the various organs constituting the actuating device.

FIG. 3 is a partial perspective view of the means for fixing to the ground the device for actuating the heald of a barrier in accordance with the present invention. The invention therefore relates to a device for actuating, between two stop positions, the heddle 1 of a barrier intended in particular to equip motorway tolls. Such a device must fulfill draconian specifications in particular as regards its reliability, speed, frequency of maintenance. Thus, it must allow for example a million toll transactions between two maintenance operations, which corresponds to two million operations for the barrier. In addition, the fact that more and more motorways are equipped with electronic tolls reinforces the conditions of reliability and speed that a device for actuating the barrier boom must fulfill.
Un dispositif d'actionnement de la lisse 1 d'une barrière conforme à l'invention comprend de façon connue
une fourche 2 destinée à recevoir la lisse 1 ; un bâti 3 comprenant un arbre d'entraînement 5 assurant au moins en partie la liaison entre la lisse 1 et des moyens moteurs 8 pneumatiques, le bâti 3 comprend également des moyens de régulation 11, 12, 13 des moyens moteurs 8.A device for actuating the rail 1 of a barrier according to the invention comprises, in a known manner a fork 2 intended to receive the arm 1; a frame 3 comprising a drive shaft 5 ensuring at least in part the connection between the heald 1 and pneumatic motor means 8, the frame 3 also comprises regulation means 11, 12, 13 of the motor means 8.
L'alimentation pneumatique est obtenue de façon classique au moyen d'un compresseur à air ultra-pur délivrant un air sec filtré et non lubrifié. Le bâti 3 du dispositif conforme à l'invention comprend un réservoir 17 muni d'un moyen de purge 18.The pneumatic supply is obtained in a conventional manner by means of an ultra-pure air compressor delivering filtered, non-lubricated dry air. The frame 3 of the device according to the invention comprises a reservoir 17 provided with a purge means 18.
A titre d'exemple non limitatif, les paramètres de fonctionnement du dispositif d'actionnement de la lisse d'une barrière conforme à l'invention sont les suivants : . pression nominale de fonctionnement : 7 bars . plage d'utilisation : 5 à 8 bars consommation d'air au régime maximum d'utilisation : 840 normo-litres/minuteBy way of nonlimiting example, the operating parameters of the device for actuating the barrier boom according to the invention are as follows:. nominal operating pressure: 7 bars. operating range: 5 to 8 bars air consumption at maximum operating speed: 840 standard liters / minute
. tension de raccordement au réseau : 220 volts mono¬ alternatif ou 24 volts continu . puissance électrique consommée : environ 20. mains connection voltage: 220 volts mono¬ alternating or 24 volts direct. electrical power consumed: about 20
. température d'utilisation : de - 20" C à + 70° C. Selon l'invention, les moyens moteurs 8 pneumatiques sont montés en bascule sur un palonnier 6 solidaire de l'arbre d'entraînement, comme cela est notamment représenté sur la figure 2.. operating temperature: from - 20 "C to + 70 ° C. According to the invention, the pneumatic motor means 8 are mounted on a rocker on a spreader 6 secured to the drive shaft, as is notably shown in the figure 2.
La fourche 2 est entraînée par l'arbre d'entraînement 5 de la lisse au moyen de moyeux 7 autoserrants ou expansibles. Cette liaison par frixion a pour avantages d'être démontable et sans jeu, d'éviter un usinage sur l'arbre moteur source d'usure et de fatigue, et enfin d'utiliser un matériel standard.The fork 2 is driven by the drive shaft 5 of the heddle by means of self-tightening or expanding hubs 7. This connection by frixion has the advantages of being removable and without play, of avoiding machining on the drive shaft which is a source of wear and fatigue, and finally of using standard equipment.
Pour pouvoir atteindre une vitesse de montée ou de descente de l'ordre de 0,5 seconde, la fourche 2 est de section creuse, réalisée dans un matériau à la fois léger
et rigide, par exemple en acier galvanisé et est en deux parties 2a, 2b maintenant la lisse 1 par serrage entre deux demi coquilles 4a, 4b.To be able to reach an ascending or descending speed of the order of 0.5 seconds, the fork 2 is of hollow section, made of a material that is both light and rigid, for example made of galvanized steel and is in two parts 2a, 2b maintaining the arm 1 by clamping between two half shells 4a, 4b.
Cette disposition particulière permet d'une part une facilité de montage et de démontage de la lisse et, d'autre part une fixation aisée de la fourche sur l'arbre d'entraînement 5.This particular arrangement allows, on the one hand, ease of assembly and disassembly of the arm and, on the other hand, easy attachment of the fork on the drive shaft 5.
De même pour limiter la masse de la lisse et pouvoir atteindre une vitesse de montée ou de descente de la lisse de 0,5 seconde, la lisse 1 est en matériau léger et rigide, notamment à base d'un alliage d'aluminium et son épaisseur est comprise entre 1 mm et 1,5 mm, en particulier de l'ordre de 1,2 mm.Likewise, in order to limit the mass of the arm and to be able to reach an ascent or descent speed of the arm of 0.5 seconds, the arm 1 is made of light and rigid material, in particular based on an aluminum alloy and its thickness is between 1 mm and 1.5 mm, in particular of the order of 1.2 mm.
Cette diminution de la masse de la lisse a également pour effet de limiter l'amortissement de la lisse en fin de mouvement.This reduction in the mass of the boom also has the effect of limiting the damping of the boom at the end of the movement.
L'amortissement de la lisse à la descente est, quant à lui, renforcé en outre par un moyen de limitation du débit d'air comprimé, destiné à réguler le mouvement de descente de la lisse 1.The damping of the beam on the descent is, in turn, further reinforced by a means of limiting the compressed air flow, intended to regulate the movement of descent of the beam 1.
Dans la réalisation préférée de l'invention représentée à la figure 1, les moyens moteurs 8 pneumatiques de l'arbre d'entraînement 5 de la lisse 1 comprennent deux vérins 8 linéaires, à double effet et double amortissement en fin de course. Ce type de vérin présente un excellent compromis prix/poids/puissance/fiabilité, une forte poussée disponible dès la mise en pression et un amortissement efficace. Ces deux vérins 8 sont munis à chacune de leur extrémité d'un embout à rotule 9, 10, de manière à permettre un fonctionnement à jeu réduit, un rattrapage des alignements et un fonctionnement silencieux.
Comme indiqué ci-dessus, les deux vérins 8 sont montés en bascule sur le palonnier 6 solidaire de l'arbre d'entraînement 5 de la lisse 1 au moyen des moyeux 7 autoserrants ou expansibles. Ce dispositif en bascule permet une utilisation des vérins avec un angle d'attaque optimal au cours de la course des pistons (variation sinusoïdale du couple moteur) . A cet effet, les deux vérins 8 sont fixés par leurs embouts à rotule 9, 10, d'une part à un support intérieur 22, du bâti 3, d'autre part à chacune des extrémités du palonnier 6.In the preferred embodiment of the invention shown in FIG. 1, the pneumatic motor means 8 of the drive shaft 5 of the heald 1 comprise two linear jacks 8, with double effect and double damping at the end of the stroke. This type of cylinder has an excellent price / weight / power / reliability compromise, a strong thrust available from pressurization and effective damping. These two jacks 8 are provided at each of their ends with a ball joint 9, 10, so as to allow operation with reduced clearance, take-up of the alignments and silent operation. As indicated above, the two jacks 8 are pivoted on the lifter 6 secured to the drive shaft 5 of the heddle 1 by means of self-tightening or expanding hubs 7. This tilting device allows the cylinders to be used with an optimal angle of attack during the piston stroke (sinusoidal variation of the engine torque). To this end, the two jacks 8 are fixed by their ball ends 9, 10, on the one hand to an internal support 22, of the frame 3, on the other hand to each of the ends of the lifter 6.
De manière à pouvoir contrôler le mouvement des moyens moteur 8, le dispositif d'actionnement conforme à l'invention comprend en outre des moyens de contrôle. A cet effet, les vérins pneumatiques 8 sont équipés d'un piston magnétique, leur détection étant assurée par des moyens de régulation 11,12, 13 qui comprennent notamment des moyens magnétique de détection 11 de la position des pistons magnétiques. Ces moyens magnétiques de détection 11 sont montés sur les corps 14 des vérins 8 et sont au nombre de quatre, deux ont pour fonction de détecter les pistons en fin de course, et deux de les détecter en position intermédiaire.In order to be able to control the movement of the motor means 8, the actuation device according to the invention further comprises control means. To this end, the pneumatic cylinders 8 are equipped with a magnetic piston, their detection being ensured by regulating means 11, 12, 13 which notably comprise magnetic means 11 for detecting the position of the magnetic pistons. These magnetic detection means 11 are mounted on the bodies 14 of the jacks 8 and are four in number, two have the function of detecting the pistons at the end of the stroke, and two of detecting them in the intermediate position.
Les moyens de régulation 11, 12, 13 comprennent également un moyen distributeur de pression 13 asservi électriquement, permettant d'établir la pression dans l'une et/ou l'autre des chambres de vérins 8 en cours de mouvement et en fonction d'une séquence de régulation prédéterminée. Comme exemple de moyens distributeurs de pression, on peut citer à titre non limitatif une électrovanne 5/3 centre ouvert d'un diamètre de passage de 8 mm.The regulating means 11, 12, 13 also comprise an electrically controlled pressure distributor means 13, making it possible to establish the pressure in one and / or the other of the chambers of jacks 8 during movement and as a function of a predetermined regulatory sequence. As an example of pressure distributing means, mention may be made, without limitation, of a 5/3 open center solenoid valve with a passage diameter of 8 mm.
Ce moyen distributeur de pression 13 est commandé par les moyens de régulation il, 12, qui comprennent un module de commande électronique 12, lequel comprend en outre des
moyens de stockage des réglages du dispositif d'actionnement conformes à l'invention. Ces moyens de stockage des réglages peuvent être, par exemple, sous la forme d'une mémoire morte programmable électriquement (EPROM) ou tout moyen équivalent.This pressure distributor means 13 is controlled by the regulating means 11, 12, which comprise an electronic control module 12, which further comprises means for storing the settings of the actuating device according to the invention. These settings storage means can be, for example, in the form of an electrically programmable read-only memory (EPROM) or any equivalent means.
On comprend ainsi de tout ce qui précède que les moyens de régulation 11, 12, 13 permettent un temps de réponse très court du dispositif conforme à l'invention, une stabilité des réglages puisque ceux-ci sont programmés, une régulation spécifique à la montée et à la descente de la lisse 1, et la possibilité de modifier les réglages par remplacement des moyens de stockage des réglages du dispositif conforme à l'invention.It is thus understood from all of the above that the regulation means 11, 12, 13 allow a very short response time of the device according to the invention, stability of the settings since these are programmed, specific regulation for the climb and when the stringer 1 is lowered, and the possibility of modifying the settings by replacing the means for storing the settings of the device according to the invention.
La gestion électronique de la commutation de 1'électrodistributeur (carte électronique à micro¬ contrôleur) permet d'obtenir, par une inversion des pressions dans les chambres de vérins en cours de mouvement, un amortissement très performant en fin de course. Cette caractéristique est très importante car la difficulté d'obtenir un amortissement puissant pour des grandes vitesses de déplacement, constitue dans l'état connu de la technique actuelle l'obstacle majeur au développement de la motorisation pneumatique pour ce type de matériel. S'agissant de la sécurité d'un tel dispositif conforme à l'invention, le verrouillage de la lisse 1 dans les deux positions d'arrêt est assuré par des moyens de maintien de la pression dans les chambres des vérins 8 après le mouvement, ces moyens étant commandés par le module de commande électronique 12. Ce maintien de la pression est garanti en cas de coupure d'alimentation ou de pression par un réservoir auxiliaire d'air comprimé, disposé à l'intérieur du bâti 3 du dispositif conforme à
l'invention, et muni d'un clapet anti-retour et d'une batterie 15.Electronic management of the switching of the electrodistributor (electronic card with micro-controller) makes it possible to obtain, by reversing the pressures in the chambers of jacks during movement, very effective damping at the end of the stroke. This characteristic is very important because the difficulty of obtaining a powerful damping for great speeds of displacement, constitutes in the known state of the current art the major obstacle to the development of the pneumatic motorization for this type of material. As regards the safety of such a device according to the invention, the locking of the heald 1 in the two stop positions is ensured by means of maintaining the pressure in the chambers of the jacks 8 after the movement, these means being controlled by the electronic control module 12. This maintenance of the pressure is guaranteed in the event of a power supply or pressure cut by an auxiliary reservoir of compressed air, disposed inside the frame 3 of the device conforming to the invention, and provided with a non-return valve and a battery 15.
Il s'ensuit l'impossibilité de manoeuvrer la lisse 1 à la main si la barrière est en fonction et l'élimination du risque de la descente intempestive de la lisse en cas de coupure de courant ou de pression.It follows the impossibility of operating the arm 1 by hand if the barrier is in operation and eliminating the risk of inadvertent descent of the arm in the event of a power or pressure cut.
La capacité du réservoir auxiliaire d'air comprimé est d'environ 2 litres et l'autonomie de la batterie 15, de l'ordre de 1 heure. Ces caractéristiques du dispositif conforme à l'invention permettent à ce dernier d'avoir une autonomie de quelques manoeuvres pour permettre le passage des véhicules en attente devant la fermeture de la voie d'autoroute en cas de panne de courant ou de pression, et permettent un maintien du verrouillage en position d'arrêt, en cas de panne ponctuelle.The capacity of the auxiliary compressed air tank is approximately 2 liters and the autonomy of the battery 15, of the order of 1 hour. These characteristics of the device according to the invention allow the latter to have an autonomy of a few maneuvers to allow the passage of vehicles on standby before the closure of the motorway lane in the event of a power or pressure failure, and allow maintaining the lock in the stop position in the event of a one-off failure.
Pour atténuer les dégâts, à la fois sur le véhicule et sur le dispositif conforme à l'invention, occasionnés par un choc violent d'un véhicule sur la barrière du dispositif de l'invention, ce dernier comprend des moyens de fixation 19 au sol, mobiles, permettant le pivotement de l'ensemble du dispositif conforme à l'invention en cas de choc.To mitigate the damage, both on the vehicle and on the device according to the invention, caused by a violent impact of a vehicle on the barrier of the device of the invention, the latter comprises fixing means 19 to the ground , mobile, allowing the entire device according to the invention to pivot in the event of an impact.
Cette fixation au sol est réalisée par pincement du fond 20 du bâti 3 au moyen de brides 19 en appui sur la périphérie d'une découpe circulaire du fond 20 du bâti 3.This fixing to the ground is carried out by pinching the bottom 20 of the frame 3 by means of flanges 19 bearing on the periphery of a circular cutout of the bottom 20 of the frame 3.
Bien entendu la présente invention ne se limite nullement au mode de réalisation choisi et représenté, mais englobe bien au contraire, toutes variantes à la portée de l'homme du métier.Of course, the present invention is in no way limited to the embodiment chosen and shown, but on the contrary encompasses all variants within the reach of the skilled person.
Ainsi par exemple, l'homme du métier pourra envisager de remplacer les vérins par tout moyen moteur à sa portée.
Thus, for example, a person skilled in the art may consider replacing the jacks by any motor means within his reach.
