Description
CROCHET DE MANUTENTION
A OUVERTURE ELECTROMAGNETIQUE SECURISEE
L'objet de l'invention concerne un système de crochet à ouverture électromagnétique commandée, équipée d'un mécanisme de sécurité con frôlant la rotation du crochet.HANDLING HOOK
WITH SECURE ELECTROMAGNETIC OPENING
The object of the invention relates to a hook system with controlled electromagnetic opening, equipped with a safety mechanism con close to the rotation of the hook.
Le dispositif est destiné à toutes manutentions dans les usines, les ports, transports ou autres, il permet de décharger tous les objets sans avoir à intervenir pour ouvrir le crochet et libérer la charge. The device is intended for all handling in factories, ports, transport or other, it allows to unload all objects without having to intervene to open the hook and release the load.
Habituellement, les industries, les ports maritimes, les transporteurs etc... étaient obligés, à tous les déchargements de wagons ou de containers, par exemple, de faire intervenir du personnel pour décrocher les charges, avec une perte de temps certaine, un danger accru, donc un prix de revient plus onéreux, et une main d'oeuvre plus importante. Usually, industries, seaports, transporters etc ... were obliged, for all unloading of wagons or containers, for example, to bring in personnel to unhook the loads, with a certain loss of time, a danger increased, therefore a more expensive cost price, and a larger workforce.
La présente invention a pour objet de supprimer ces diverses manutentions, et permet de décrocher la charge à l'aide d'un appareil de commande. The object of the present invention is to eliminate these various handling operations, and allows the load to be picked up using a control device.
Le dispositif suivant l'invention comporte en effet un crochet fermé par un mousqueton. L'ensemble est solidaire du corps fixé à un palan ou tout autre élément de levage. Pour permettre le décrochage de la charge, le crochet tourne autour d'un axe. Le blocage du crochet est provoqué par le déplacement d'un doigt, dépendant d'un électroaimant. Ce doigt empêche la rotation du crochet, et par conséquent le décrochage de la charge. L'ouverture du crochet ne peut s'effectuer que lorsque la charge est posée. Sous l'action du propre poids de la charge, le crochet appuie sur le doigt, et même si le manipulateur commande par erreur l'ouverture du crochet, alors que la charge est suspendue, le doigt reste bloqué par cette action mécanique. Le système est donc auto-bloquant
L'invention sera mieux comprise à la lecture de la description détaillée ci-dessous, et à l'examen des dessins annexés qui représentent à titre d'exemple non limitatif, I'une des formes de réalisation de ladite invention. Le crochet à ouverture électromagnétique sécurisée, est représenté vu en coupe et en vue de droite. The device according to the invention in fact comprises a hook closed by a carabiner. The assembly is integral with the body fixed to a hoist or any other lifting element. To allow the load to be released, the hook rotates around an axis. The blocking of the hook is caused by the movement of a finger, dependent on an electromagnet. This finger prevents rotation of the hook, and therefore the detachment of the load. The hook can only be opened when the load is placed. Under the action of the load's own weight, the hook presses on the finger, and even if the manipulator mistakenly commands the opening of the hook, while the load is suspended, the finger remains blocked by this mechanical action. The system is therefore self-locking
The invention will be better understood on reading the detailed description below, and on examining the appended drawings which represent, by way of nonlimiting example, one of the embodiments of said invention. The hook with secure electromagnetic opening, is shown seen in section and in right view.
Sur ces dessins:
L'ensemble d'accrochage est constitué par un crochet 1, le corps de l'ensemble 2, la chape 3 d'accrochage au palan, un électroaimant 4 alimenté par un câble électrique 5 lui même protégé par une sortie de câble 8, et un ressort 6 permettant le blocage d'un mousqueton de refenue 7.In these drawings:
The attachment assembly is constituted by a hook 1, the body of the assembly 2, the yoke 3 for attachment to the hoist, an electromagnet 4 powered by an electric cable 5 itself protected by a cable outlet 8, and a spring 6 allowing the locking of a locking carabiner 7.
Le crochet 1 à mouvement pendulaire, est tenu au corps par l'axe 10.The hook 1 with pendulum movement is held to the body by the axis 10.
Le mousqueton de retenue 7 est tenu au corps par l'axe 9.The retaining carabiner 7 is held to the body by the pin 9.
Les goupilles Il et 12 empêchent les axes 9 et 10 de sortir de leurs logements.Pins 11 and 12 prevent pins 9 and 10 from coming out of their housings.
La chape 3 est solidaire du corps par des boulons 17.The yoke 3 is secured to the body by bolts 17.
La pièce appelée doigt 13 coulisse à l'intérieur du corps 2. Le déplacement du doigt est guidé par un boulon 14, et il est obtenu par la translation du noyau 15 à l'intérieur de l'électroaimant 4.The part called finger 13 slides inside the body 2. The movement of the finger is guided by a bolt 14, and it is obtained by the translation of the core 15 inside the electromagnet 4.
Le noyau 15 est solidaire du doigt 13 par un axe 16.The core 15 is secured to the finger 13 by an axis 16.
Le crochet 1 possède une surface plane qui vient s'appuyer contre le doigt 13 lorsque celui-ci est descendu. Le système est auto-bloquant. The hook 1 has a flat surface which comes to bear against the finger 13 when the latter is lowered. The system is self-locking.
Un ressort 19 pousse le noyau 15 de façon a ce que le doigt 13 reprenne sa positions initiale.A spring 19 pushes the core 15 so that the finger 13 returns to its initial position.
Un détecteur de position 18 du doigt 13 empêche toute manipulation si le doigt n'est pas à sa place initiale. A position detector 18 of the finger 13 prevents manipulation if the finger is not in its original place.
