Description
Chariot de manutention de tôles
La présente invention concerne un chariot de manutention de tôles.Sheet handling trolley
The present invention relates to a sheet handling trolley.
Plus particulièrement, l'invention s'applique à la manutention de tôles utilisées dans les chantiers de travaux publics pour permettre le passage de piétons ou de véhicules transversalement à une tranchée effectuée dans la chaussée. Lors de la réalisation de telles tranchées, pour la mise en place de tuyauteries, câbles, etc..., il est nécessaire de manipuler plusieurs fois de telles tôles. Or, ces tôles sont relativement épaisses et donc très lourdes, de l'ordre de 130 kg, et leur manipulation répétée est ainsi très fatigante.More particularly, the invention applies to the handling of sheets used in public works sites to allow the passage of pedestrians or vehicles transversely to a trench made in the roadway. When making such trenches, for the installation of pipes, cables, etc., it is necessary to manipulate such sheets several times. However, these sheets are relatively thick and therefore very heavy, of the order of 130 kg, and their repeated handling is thus very tiring.
La présente invention a donc pour but de diminuer considérablement la fatigue, et donc les incidents ou accidents qui peuvent en résulter, des hommes appelés à mouvoir plusieurs fois par jour de telles tôles. The object of the present invention is therefore to considerably reduce the fatigue, and therefore the incidents or accidents which may result therefrom, of men called upon to move such sheets several times a day.
L'invention a ainsi pour objet un chariot de manutention de tôles, caractérisé en ce qu'il comprend un cadre monté sur deux roues latérales et comportant une extrémité supérieure se terminant par deux bras munis chacun d'une poignée, et une extrémité inférieure, en avant desdites roues par rapport aux poignées, en appui sur le sol en position de repos, et portant des moyens de préhension formant un bec dans lequel peut venir se placer un bord de tôle, la partie supérieure dudit cadre supportant au moins un rail, sensiblement horizontal et dirigé longitudinalement dans la direction allant des poignées vers les roues, auquel est suspendu un contre-poids, mobile le long dudit rail, permettant de déplacer longitudinalement la projection du centre de gravité du chariot par rapport à son polygone de sustentation délimité par les roues et l'extrémité inférieure avant dudit cadre. The subject of the invention is therefore a sheet handling trolley, characterized in that it comprises a frame mounted on two lateral wheels and comprising an upper end ending in two arms each provided with a handle, and a lower end, in front of said wheels relative to the handles, bearing on the ground in the rest position, and carrying gripping means forming a spout in which a sheet metal edge can be placed, the upper part of said frame supporting at least one rail, substantially horizontal and directed longitudinally in the direction from the handles towards the wheels, on which hangs a counterweight, movable along said rail, making it possible to longitudinally move the projection of the center of gravity of the trolley with respect to its support polygon delimited by the wheels and the lower front end of said frame.
Selon une autre caractéristique, lesdits moyens de préhension sont liés à un coulisseau pouvant coulisser sensiblement verticalement le long de l'extrémité inférieure dudit cadre. According to another characteristic, said gripping means are linked to a slide which can slide substantially vertically along the lower end of said frame.
On va maintenant donner la description d'un exemple de mise en oeuvre de l'invention en se référant au dessin annexé dans lequel
La figure 1 montre en élévation un chariot selon l'invention.We will now give the description of an example of implementation of the invention with reference to the accompanying drawing in which
Figure 1 shows in elevation a carriage according to the invention.
La figure 2 est une vue de dessus de la figure 1. Figure 2 is a top view of Figure 1.
La figure 3 est une vue de gauche de la figure 1. Figure 3 is a left view of Figure 1.
La figure 4 est une vue de droite de la figure 1. Figure 4 is a right view of Figure 1.
La figure 5 est une vue partielle agrandie selon la flèche V de la figure 2. FIG. 5 is a partial enlarged view along arrow V of FIG. 2.
La figure 6 est une vue partielle agrandie en coupe selon VI-VI de la figure 2. FIG. 6 is an enlarged partial view in section on VI-VI of FIG. 2.
La figure 7 est- une vue selon la flèche VII de la figure 6. FIG. 7 is a view according to arrow VII of FIG. 6.
En se référant aux figures 1 à 4, le chariot selon l'invention comprend un cadre 1 formé de tubes soudés, comprenant deux tubes latéraux 2 et 3 coudés presque à l'équerre dont les extrémités supérieures forment des bras sensiblement horizontaux, en position de repos du chariot, se terminant par deux poignées 4 et 5. Les extrémités inférieures des tubes coudés 2 et 3 sont soudées à un étrier 6 formé de deux cornières à section en équerre 7 et 8 et de deux fers plats 9 et 10. Cet étrier 6 constitue l'extrémité inférieure avant du cadre 1. Le cadre 1 est renforcé par deux tubes obliques Il et 12, une console avant 13 et une traverse arrière 14.Ce cadre l est monté sur deux roues latérales 15 et 15 aux extrémités d'un axe 52 soudé aux extrémités inférieures des tubes obliques ll et 12; En position de repos du chariot, celui-ci repose d'une part sur ses roues 15 et 16, et d'autre part, contre la cornière en équerre 8 de l'étrier 6 formant l'extrémité inférieure avant du cadre 1. Cette extrémité inférieure avant du cadre l porte des moyens de préhension 17 formant un bec dont la partie inférieure 18 est légèrement biseautée, et plus longue que la partie supérieure 19. Ces moyens de préhension 17 sont iiés à un coulisseau 20 qui peut coulisser librement le long de tiges 21 et 22, enfilés et soudés dans l'extrémité des tubes coudés 2 et 3 et reposant contre la corniere inférieure 8 de l'étrier 5. Referring to Figures 1 to 4, the carriage according to the invention comprises a frame 1 formed of welded tubes, comprising two lateral tubes 2 and 3 bent almost square, the upper ends of which form substantially horizontal arms, in the position of carriage rest, ending with two handles 4 and 5. The lower ends of the bent tubes 2 and 3 are welded to a stirrup 6 formed by two angled section angles 7 and 8 and two flat bars 9 and 10. This stirrup 6 constitutes the lower front end of the frame 1. The frame 1 is reinforced by two oblique tubes Il and 12, a front console 13 and a rear cross member 14.This frame l is mounted on two side wheels 15 and 15 at the ends of an axis 52 welded to the lower ends of the oblique tubes 11 and 12; In the rest position of the carriage, the latter rests on the one hand on its wheels 15 and 16, and on the other hand, against the square angle 8 of the stirrup 6 forming the lower front end of the frame 1. This lower front end of the frame l carries gripping means 17 forming a spout the lower part 18 of which is slightly bevelled, and longer than the upper part 19. These gripping means 17 are linked to a slide 20 which can slide freely along rods 21 and 22, threaded and welded into the end of the bent tubes 2 and 3 and resting against the lower angle 8 of the stirrup 5.
Ces moyens de préhension 17 permettent ainsi de manutentionner une tôle telle que la tôle 23, figure 1. La possiWilité de coulissement le long des tiges 21 et 22 permettent de prendre une tôle située non pas sur la chaussée, mais par exemple sur un trottoir, le chariot étant lui sur la chaussée. These gripping means 17 thus make it possible to handle a sheet metal such as sheet metal 23, FIG. 1. The possibility of sliding along the rods 21 and 22 makes it possible to take a sheet metal located not on the roadway, but for example on a sidewalk, the cart being him on the road.
Enfin, le chariot est muni d'un ccntre-pcids 24 mobile le long de deux rails guides 25 et 25 fixés longitud nalement sur la conscle avant I et la traverse arrière 14. Les figures e et 7 montrent le dispositif ce suspension d contre-poids 24 aux rails 25 et 2e par l'interné- diaire d'un fer en U 27 et de deux paires de galets de roulement : 28 et 29 pour le rail 25 ; 30 et 31 pour le rail 26. Seul le galet 31 est visible pour la paire de galets 30 et 31 du rail 26. Chaque galet comporte deux bandes de roulements : 32 et 33 pour le galet 31.Les deux galets d'une même paire, par exemple les galets 30 et 31 sont montés entre deux flasques 34 et 35. Au milieu de ces flasques est situé un bloc support 37 qui tourillonne dans les flasques 34 et 35. L'ensemble contre-poids 24, fer en U 27 est suspendu à ces deux paires de galets 28-29 et 30-31 par deux tiges 38 et 39 qui traversent respectivement le bloc 37 et celui, non visible, de la paire de galets 29-30. Les extrémités des tiges 38 et 39 portent une butée d'appui 40, 41 s'appuyant sur le sommet de ces blocs supports. Finally, the carriage is provided with a mobile pc-center 24 along two guide rails 25 and 25 fixed longitudinally on the front section I and the rear cross member 14. FIGS. E and 7 show the device this suspension of counter weight 24 on rails 25 and 2e by means of a U-shaped iron 27 and two pairs of rollers: 28 and 29 for rail 25; 30 and 31 for the rail 26. Only the roller 31 is visible for the pair of rollers 30 and 31 of the rail 26. Each roller has two bearing strips: 32 and 33 for the roller 31. The two rollers of the same pair , for example the rollers 30 and 31 are mounted between two flanges 34 and 35. In the middle of these flanges is located a support block 37 which pivots in the flanges 34 and 35. The counterweight assembly 24, U-shaped iron 27 is suspended from these two pairs of rollers 28-29 and 30-31 by two rods 38 and 39 which pass respectively through block 37 and that, not visible, of the pair of rollers 29-30. The ends of the rods 38 and 39 carry a support stop 40, 41 resting on the top of these support blocks.
Le déplacement du contre-poids 24 le long des rails 25 et 26 est effectué au moyen d'une tige 42 articulée à un portique 43 soudé au fer en U 27 et se plaçant entre les deux rails de guidage 25 et 26. La tige 42 se termine par une poignée 43 et comprend des ergots d'immobilisation 44, 45 pouvant se placer dans des logements de blocage 46 et 47 fixés aux rails 25 et 26. The displacement of the counterweight 24 along the rails 25 and 26 is effected by means of a rod 42 articulated to a gantry 43 welded to the U-shaped iron 27 and being placed between the two guide rails 25 and 26. The rod 42 ends with a handle 43 and comprises immobilizing lugs 44, 45 which can be placed in blocking housings 46 and 47 fixed to the rails 25 and 26.
Ainsi, grâce à ce système de contre-poids mobile longitudinalement, on peut placer ce contre-poids, soit vers l'avant, comme représenté en traits forts sur la figure 1, soit, vers l'arrière, comme représenté en pointillés sur cette figure, lorsque l'on manutentionne une tôle 23. Thus, thanks to this longitudinally movable counterweight system, this counterweight can be placed either forwards, as shown in strong lines in FIG. 1, or, toward the rear, as shown in dotted lines in this figure, when handling a sheet 23.
Dans les deux cas, la tige de manoeuvre 42 est rabattue d'un côté ou de l'autre avec les ergots 44-45 logés dans les logements de blocage 46 et 47 immobilisant le contre-poids 24 dans sa position longitudinale.In both cases, the operating rod 42 is folded down on one side or the other with the lugs 44-45 housed in the blocking housings 46 and 47 immobilizing the counterweight 24 in its longitudinal position.
La figure 5 montre la fixation des rails 25 et 26 contre la console avant 13. Un fer en U 48 est soudé à la console avant 13 et les rails 25 et 26 sont fixés à ce fer par des vis 49, 50 munies d'écrous et de contre-écrous. Les contre-écrous servent en outre de butée d'arrêt pour les galets de roulement de l'équipage mobile. Une traverse supérieure 51 soudée aux rails 25 et 26 consolide l'assemblage. La fixation des rails 25 et 26 sur la traverse arrière 14 est réalisée de la même manière. FIG. 5 shows the fixing of the rails 25 and 26 against the front console 13. A U-shaped iron 48 is welded to the front console 13 and the rails 25 and 26 are fixed to this iron by screws 49, 50 provided with nuts and lock nuts. The lock nuts also serve as a stop for the rollers of the moving assembly. An upper cross member 51 welded to the rails 25 and 26 consolidates the assembly. The fixing of the rails 25 and 26 on the rear cross member 14 is carried out in the same way.
