Abstract

Plancher de fosse de réparation (repair pit) ajustable en hauteur au millimètre de façon a trouver la position parfaite de travail. Ce plancher une fois fermé, couvre complètement la fosse et son système de barrure lui permet de supporter d'énormes charges. La plate-forme , en descendant dans la fosse, dépose les marches pour former l'escalier et lorsqu'elle remonte en place, ramasse toutes ses marches pour finir en un plancher complètement uni.Repair pit floor adjustable in height to the millimeter in order to find the perfect working position. This floor, once closed, completely covers the pit and its locking system allows it to withstand enormous loads. The platform, going down into the pit, deposits the steps to form the staircase and when it goes back up, collects all of its steps to end up in a completely level floor.

Description

Description Généralement, une fosse de réparation (repair pit), lorsqu'elle n'est pas en service, doit être recouverte ou entourée d'un dispositif de sécurité pour éviter les accidents.

L'invention concerne une plate-forme et son mécanisme qui, une fois placés dans la fosse de réparation est autonome et sécuritaire. Mû par la force hydraulique, la plate-forme s'ajuste a la hauteur désirée au millimètre près. Lors de sa descente, la plate-forme dépose ses marches et les récupère a sa remontée. Lorsque complètement remontée, elle couvre toute la fosse de réparation rendant inutile l'installation de cônes de sécurité ou chevalets et la conception des pivots lui permet de supporter des camions chargés.

La Figure 1 est une vue de l'ensemble du système pour une fosse de réparation en position montée.

Montée sur un châssis de fort calibre (1), l'invention est opérée par 2 cylindres hydrauliques (3) qui en poussant sur des pivots (2), permettent la montée ou la descente. Les pivots, contrairement a la pratique habituelle, ne fonctionnent pas en ciseau mais sur un arc de près de 180 degrés ce qui permet en fin de course de barrer la plate-forme pour lui assurer la force de soutenir de lourdes charges. Le ciseau (4) n'est la que pour guider le mouvement de montée en ligne droite.

La Figure 2 est une vue du châssis d'escalier Un châssis d'escalier (13) est monté en place et rattaché en permanence au châssis principal (1).
La Figure 3 montre une marche avec son système de localisation.

Chaque marche (10), lors de la descente du plancher, est déposée exactement a sa place, guidée par la contremarche (14). Des localisateurs (12) et des ancrages (11) servent a positionner et ancrer la marche dans les tubes (15) du châssis et l'engagement se fait seulement par le poids de la marche. La forme triangulaire de l'ancrage (11) permet une insertion et un centrage de ce dernier dans le tube (15) de façon a garder la marche a la même position. A la remontée, le châssis principal ne fait que soulever la marche qui redevient alors partie de la plate-forme. La Figure 4 montre les marches (10) en place une fois le plancher remonté (vue d'en dessous).

La Figure 5 illustre le pivot (2) a sa position barrée (haut). On notera que l'ensemble n'est pas exactement a 180 degrés mais excède légèrement de façon a créer l'effet de barrure. Vu le côté
sécurité, cette barrure est de 2 niveaux : le premier niveau implique la fin de course du cylindre et le deuxième niveau est la portée d'une jambe du pivot dans l'autre qui le bloque a cause du léger fléchissement arrière de l'ensemble. Description Generally, a repair pit, when it is not in service, must be covered or surrounded by a safety device to prevent accidents.

The invention relates to a platform and its mechanism which, once placed in the pit of repair is autonomous and safe. Powered by hydraulic force, the platform shape adjusts to the desired height to the nearest millimeter. During its descent, the platform drops his steps and the recover at its ascent. When completely reassembled, it covers the entire pit of repair making unnecessary the installation of safety cones or trestles and the design of pivots allows it to support loaded trucks.

Figure 1 is an overview of the entire system for a repair pit in position climb.

Mounted on a heavy gauge frame (1), the invention is operated by 2 hydraulic cylinders (3) which by pushing on pivots (2), allow the rise or the descent. The pivots, contrary to the usual practice, do not work in chisel but on an arch of almost 180 degrees which allows the end of the race to block the platform for him ensure the strength of support heavy loads. The chisel (4) is only for guiding the uphill move straight line.

Figure 2 is a view of the stair frame A staircase (13) is mounted in place and permanently attached to the main frame (1).
Figure 3 shows a walk with its location system.

Each step (10), when the floor is lowered, is deposited exactly his place, guided by the riser (14). Locators (12) and anchors (11) serve to position and anchor the step in the tubes (15) of the chassis and the commitment is made only by the weight of walking. The triangular shape of the anchor (11) allows insertion and centering this last in the tube (15) so as to keep walking in the same position. To the ascent, the main frame only lifts the step which then becomes part of the platform. The Figure 4 shows the steps (10) in place once the floor is raised (view from below).

Figure 5 illustrates the pivot (2) in its locked position (top). It will be noted that the whole is not exactly 180 degrees but slightly exceeds the effect of barrure. Given the side security, this lock is of 2 levels: the first level implies the end race cylinder and the second level is the reach of one leg of the pivot in the other which the hangs because of slight backward sagging of the set.

2 Précis de la divulgation Plancher de fosse de réparation (repair pit) ajustable en hauteur au millimètre de façon a trouver la position parfaite de travail. Ce plancher une fois levé, couvre complètement la fosse et son système de barrure a deux niveaux lui permet même de supporter un camion chargé. La plate-forme, en descendant dans la fosse, dépose les marches pour former l'escalier et lorsqu'elle remonte en place, ramasse toutes ses marches pour finir en un plancher complètement uni. Une fosse de réparation doit quand elle ne sert pas, être, soit recouverte, soit entourée de cônes de sécurité ou chevalets par mesure de sécurité. Parce que ce plancher ne laisse aucune ouverture une fois fermé, ces mesures ne sont pas nécessaires. 2 Accuracy of disclosure Repair pit floor adjustable in height at millimeter of how to find the perfect working position. This floor when lifted, covers completely the pit and its two-level locking system even allows it to support a truck charge. The platform form, going down into the pit, laying the steps to form the stairs and when go back up, pick up all its steps to finish in a floor completely united. A
repair pit must when it does not serve, be, either covered or surrounded by cones safety or trestles for safety. Because this floor leaves no opening once closed, these measures are not necessary.
