Abstract
Description
-1- La présente invention concerne un dispositif de mesure d'efforts de manipulation de chariot de manutention. Ce chariot peut être un transpalette ou un dispositif similaire répondant au critère suivant : le chariot est tiré ou poussé, par l'intermédiaire d'une poignée, laquelle est reliée au chariot par un manche. La surveillance des risques du travail, liés à la manutention de charges au moyen de tels chariots, nécessite de mesurer les efforts réels développés par les opérateurs de manutention, et d'enregistrer les mesures sur des périodes plus ou moins longues. Il existe actuellement divers dispositifs de mesure de force, cependant il n'existe pas de dispositif permettant d'effectuer des mesures d'effort sur un chariot de manutention, sans modification du chariot, et sans perturber la mesure, c'est-à-dire sans modifier les conditions d'utilisation du chariot. L'idée sur laquelle s'appuie la présente invention consiste à adjoindre une poignée de substitution au chariot (laquelle sera située à seulement quelques centimètres de la poignée du chariot, afin de ne pas perturber l'utilisation normale du chariot), et à intercaler un ou des capteurs d'efforts, entre la poignée du chariot et la poignée de substitution. C'est donc la poignée de substitution qui sera utilisée à la place de la poignée du chariot, durant toute la période de mesure. Le dispositif selon l'invention comporte un châssis (5) léger mais rigide. Ce châssis est muni de deux brides de fixation (3), destinées à enserrer la zone de préhension de la poignée du chariot, ainsi qu'une bride de fixation (4), destinée à enserrer le manche (8) du chariot. Les deux brides (1) sont suffisamment espacées pour ne pas entrer en conflit avec le manche (8), qui se prolonge jusqu'à cette -2- partie préhensile, sur certains types de transpalette. Les 35 brides (3) et (4) peuvent être aisément interchangées pour pouvoir s'adapter à d'autres types de chariots, par exemple ceux dont le manche est rond et non rectangulaire. La poignée de substitution (2) est reliée au moyen d'un ou plusieurs capteur(s) de force au châssis. Il peut s'agir, 40 indifféremment, d'un capteur d'effort multiaxial ou de plusieurs capteurs mono-axiaux placés selon un angle déterminé. Par exemple, sur les figures a et b, il s'agit de deux capteurs mono-axiaux (1), positionnés perpendiculairement.The present invention relates to a device for measuring handling forces of a handling trolley. This carriage can be a pallet truck or similar device meeting the following criterion: the carriage is pulled or pushed, via a handle, which is connected to the carriage by a handle. The monitoring of the risks of the work, related to the handling of loads by means of such trolleys, requires to measure the real efforts developed by the handling operators, and to record the measurements over more or less long periods. There are currently various force measuring devices, however there is no device for making effort measurements on a truck, without modification of the truck, and without disturbing the measurement, that is to say say without changing the conditions of use of the truck. The idea on which the present invention is based to add a handle substitution of the carriage (which will be located only a few inches from the handle of the carriage, so as not to disturb the normal use of the carriage), and to insert one or more force sensors, between the handle of the carriage and the substitution handle. It is therefore the substitution handle that will be used instead of the handle of the carriage, during the entire measurement period. The device according to the invention comprises a frame (5) light but rigid. This frame is provided with two fixing flanges (3) for gripping the gripping area of the handle of the carriage, and a fixing flange (4) for gripping the handle (8) of the carriage. The two flanges (1) are sufficiently spaced to not conflict with the handle (8), which extends to this prehensile portion, on certain types of pallet truck. The flanges (3) and (4) can be easily interchanged to accommodate other types of trolleys, for example those with a round, non-rectangular handle. The substitution handle (2) is connected by means of one or more force sensors to the frame. It may be, indifferently, a multiaxial force sensor or several mono-axial sensors placed at a given angle. For example, in Figures a and b, there are two mono-axial sensors (1), positioned perpendicularly.
45 Les capteurs d'effort sont reliés à un dispositif standard (ou non standard) d'acquisition et de stockage des mesures, lequel est inclus dans le carter (6). Optionnellement, un cache (7) pourra masquer et/ou rendre mal pratique l'usage de la poignée du chariot, sans gêner 50 toutefois l'usage de la poignée de substitution, afin de préserver l'opérateur de la tentation d'utiliser la poignée du chariot, ce qui fausserait la mesure. Le dispositif selon l'invention est particulièrement destiné à l'usage de la prévention des risques au travail, 55 pour les entreprises nécessitant l'usage de chariots de type transpalette.The force sensors are connected to a standard (or non-standard) measurement acquisition and storage device, which is included in the housing (6). Optionally, a cover (7) may hide and / or mishandle the use of the handle of the carriage, without interfering 50 however the use of the handle substitution, to preserve the operator of the temptation to use the handle of the cart, which would distort the measure. The device according to the invention is particularly intended for the use of the prevention of risks at work, 55 for companies requiring the use of pallet trucks.
