Description

2869578 -1-2869578 -1-

La présente invention concerne un dispositif de cale de sécurité télécommandé à distance pour l'immobilisation d'un véhicule de type poids lourd ou remorque au quai de chargement. The present invention relates to a remote-controlled safety wedge device for immobilizing a truck-type vehicle or trailer at the loading dock.

Actuellement, l'immobilisation des véhicules à quai est faite par le chauffeur du camion en chargement/déchargement sans caractère d'obligation pour le chauffeur et sans que le cariste manutentionnaire ait le pouvoir de contrôler sa propre sécurité. Currently, the immobilization of vehicles at the dock is made by the driver of the truck loading / unloading of no obligation for the driver and without the cargo handler has the power to control his own safety.

Certaines cales existent déjà mais toujours sans caractère d'obligation ni de contrôle par le cariste/manutentionnaire. Ceci entraînant des risques importants lors des mouvements de véhicules. En effet le chauffeur est obligé d'avancer son véhicule pour refermer les portes du camion; de nombreux accidents ont lieu à ce moment, le cariste se trouvant encore à l'intérieur du véhicule en mouvement. Some holds already exist but still without obligation or control by the driver / handler. This involves significant risks when moving vehicles. Indeed the driver is obliged to advance his vehicle to close the doors of the truck; many accidents occur at this time, the driver still being inside the moving vehicle.

Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this disadvantage.

II s'agit en effet d'un dispositif de cale mobile géré par le cariste manutentionnaire qui en assure la mise en place pour le blocage du véhicule et le retrait après chargement grâce à une télécommande en sa possession. It is indeed a mobile hold device managed by the truck driver who ensures the implementation for the blocking of the vehicle and withdrawal after loading with a remote control in his possession.

Cette cale montée sur un chariot est placée devant la roue du camion arrêté à quai (côté gauche du véhicule). Une fois la cale placée, un système de vérin télécommandé à distance rapproche l'autre partie du système, soit une plaque épousant la forme du pneu, bloquant ainsi la roue des deux côtés sans possibilité de retrait latéral de la cale. L'opération en sens inverse devra être effectuée par le cariste à l'aide de sa télécommande personnelle pour libérer la roue. This wedge mounted on a trolley is placed in front of the truck wheel stopped at the dock (left side of the vehicle). Once the shim is placed, a remotely controlled cylinder system brings the other part closer to the system, a plate matching the shape of the tire, thus blocking the wheel on both sides without the possibility of lateral removal of the shim. The operation in the opposite direction must be carried out by the driver using his personal remote control to release the wheel.

Selon les modes particuliers de réalisation: - un gyrophare a été fixé sur le pupitre du chariot, toujours pour des raisons de sécurité, lors de la mise en place de la cale (se protéger des autres véhicules en manoeuvre). According to particular embodiments: - a beacon has been fixed on the desk of the truck, still for safety reasons, during the implementation of the wedge (to protect other vehicles in operation).

- Toujours dans un souci de protection de l'utilisateur, un coupe-circuit a été installé sur le pupitre en cas de problème électrique ou autre. Son utilisation n'engendrera pas le déverrouillage du système de vérin, qui pourra être effectué à l'aide d'une clé en possession du cariste/manutentionnaire. - Always in the interest of protecting the user, a circuit breaker has been installed on the desk in case of electrical or other problems. Its use will not result in the unlocking of the jack system, which can be carried out using a key in the possession of the driver / handler.

En référence à ces dessins, le dispositif comporte un chariot (1) composé d'un pupitre (2) équipé d'un gyrophare (3) et d'un coupe- circuit (4) ainsi que d'un boîtier électronique (5) permettant la transformation du 220 V en 24 V pour la télécommande (6) - (6") antenne de la télécommande. A ce boîtier est raccordé le câble d'alimentation électrique (7). With reference to these drawings, the device comprises a carriage (1) composed of a desk (2) equipped with a beacon (3) and a circuit breaker (4) as well as an electronic box (5). allowing the transformation of the 220 V into 24 V for the remote control (6) - (6 ") antenna of the remote control To this housing is connected the power supply cable (7).

Sur la partie inférieure du chariot se trouve le vérin (8) dont les caractéristiques du moteur (9) sont les suivantes: Classe d'isolement: F. CC - Etanchéité moteur IP67 Le vérin (8) est fixé sur une plaque de support (21) ainsi que deux tubes guides creux (23) qui reçoivent chacun, par coulissage, une tige lisse (24), de diamètre légèrement inférieur, chaque tige étant fixée à une plaque (10)(20), le tout composant la partie mobile du vérin (8) assurant ainsi la stabilité de cette même partie mobile dudit vérin (8). On the lower part of the truck is the cylinder (8) whose characteristics of the motor (9) are as follows: Insulation class: F. DC - IP67 motor sealing The cylinder (8) is fixed on a support plate ( 21) and two hollow guide tubes (23) which each receive, by sliding, a smooth rod (24) of slightly smaller diameter, each rod being fixed to a plate (10) (20), the whole constituting the moving part. cylinder (8) thus ensuring the stability of the same movable portion of said cylinder (8).

A La partie mobile du vérin (8) est fixée, grâce à une platine (25), (permettant un réglage en cas d'utilisation hors normes) une plaque (10) Alimentation: 230 V - 50 Hz Puissance: 280 W Absorption: 1.2 - 1.7 A TR/min: 1400g/min 2869578 -3- (20) présentant un relief anti-dérapant et épousant la forme du pneu du camion (Il). A The movable part of the cylinder (8) is fixed, thanks to a plate (25), (allowing an adjustment in case of abnormal use) a plate (10) Power supply: 230 V - 50 Hz Power: 280 W Absorption: 1.2 - 1.7 A RPM: 1400g / min 2869578 -3- (20) having a non-slip relief and conforming to the shape of the truck tire (II).

Toujours, sur la partie inférieure du chariot, est fixée la cale (12) de la largeur d'un pneu standard, dont la partie incurvée dépasse 5 à droite du chariot afin d'épouser la roue. Still, on the lower part of the carriage, is fixed the shim (12) of the width of a standard tire, the curved portion of which exceeds 5 to the right of the carriage to marry the wheel.

Le chariot est muni de deux roues pleines (13) légèrement surélevées, utilisables seulement lors de l'inclinaison du chariot pour le déplacement de celui. De ce fait, ces roues ne gênent pas la mise en place de la cale (12) une fois le chariot redressé. The carriage is provided with two full wheels (13) slightly elevated, usable only when the inclination of the carriage for moving the one. As a result, these wheels do not interfere with the setting up of the shim (12) once the carriage has been straightened.

Une autre roue (14), plus petite, en caoutchouc souple, soudée également sur la cale (12), permet quant à elle le déplacement latéral de la cale lors de l'utilisation du vérin (8) ; elle facilite ainsi les manoeuvres de mise en place et de retrait du dispositif. Another wheel (14), smaller, flexible rubber, also welded on the wedge (12), allows for it lateral displacement of the wedge when using the cylinder (8); it thus facilitates the maneuvers of setting up and removing the device.

Avant la mise en place du chariot (1), pour la protection du manipulateur, le gyrophare (3) est enclenché grâce à l'interrupteur (15). Une fois le chariot installé, le manutentionnaire/cariste actionne, par télécommande (6), le vérin qui rapproche la plaque (10) de la roue jusqu'au blocage de la cale (12) immobilisant ainsi le véhicule. Par précaution, un bouton poussoir (16) a été installé, ceci pour permettre au cariste de vérifier si la cale a été mise en place. Dans le cas contraire, s'il actionne sa télécommande, la biellette (17) presse le bouton poussoir déclenchant une alarme sonore (18), lui indiquant qu'il n'y a pas de roue bloquée. Before placing the carriage (1), for the protection of the manipulator, the beacon (3) is engaged by the switch (15). Once the trolley is installed, the handler / operator activates, by remote control (6), the cylinder that brings the plate (10) of the wheel until blocking the wedge (12) thus immobilizing the vehicle. As a precaution, a push button (16) was installed, this to allow the driver to check if the shim was put in place. In the opposite case, if it actuates its remote control, the link (17) presses the push button triggering an audible alarm (18), indicating that there is no locked wheel.

Le vérin peut être également actionné manuellement, grâce à une clé 25 (19)(19") en cas de coupure de courant. The cylinder can also be operated manually, by means of a key (19) (19 ") in case of power failure.

Le système électrique est protégé par un disjoncteur différentiel de 10 Ampères. The electrical system is protected by a 10 Amp differential circuit breaker.
