Abstract
Description
Le brevet principal a pour objet un appareil de levage et manutention comportant un mat principal fixé sur une structure en U reposant sur quatre roulettes, sur le mat principal est enfilé un coulis seau sur lequel sont fixés deux longerons supportant les bras de soutènement de charge,réglables en largeur, sur le coulisseau est fixé un appareil de traction permettant d'élever ou d'abaisser les charges. The main patent relates to a lifting and handling device comprising a main mast fixed on a U-shaped structure resting on four casters, on the main mast is slipped a bucket grout on which are fixed two beams supporting the load support arms, adjustable in width, a traction device is fixed on the slide to raise or lower the loads.
Ce genre d'appareil présente un inconvénient au niveau du déplacement de charge dans le sens vertical car compte tenu que la charge est en porte à faux par rapport au mat principal les forces contraires ou couple rapportées aux extrémités du coulis seau engen drent une résistance au glissement importante imposant un appareil de traction ayant une force de levage supérieure à la charge à déplacer verticalement. This type of device has a disadvantage in terms of the displacement of the load in the vertical direction because, given that the load is cantilevered relative to the main mast, the opposite forces or torque reported at the ends of the grout bucket generate resistance to significant slip requiring a traction device having a lifting force greater than the load to be moved vertically.
L'addition a pour but de palier à l'inconvénient précédemment exposé ainsi qu'apporter certains perfectionnements à l'appareil objet du brevet principal. The purpose of the addition is to overcome the drawback previously explained, as well as to bring certain improvements to the apparatus which is the subject of the main patent.
L'addition a pour objet un coulisseau s'enfilant sur le mat principal comportant en chacune de ses extrémités auxquelles les forces dues à la charge sont appliquées, un galet facilitant sont déplacement sur le mât, selon un perfectionnement le mât en sa partie supérieure est doté d'une tête amovible sur laquelle se raccorde le câble de l'appareil de traction permettant de prolonger ou réduire la hauteur dudit mat au moyen de ralonges amovibles s'emboitant entre elles et à l'intérieur du mât principal et dont les faces recevant les galets du coulis seau se profilent avec les faces dudit mat principal. The object of the addition is a slide threading on the main mast comprising at each of its ends to which the forces due to the load are applied, a facilitating roller are displacement on the mast, according to an improvement the mast in its upper part is fitted with a removable head to which the cable of the traction device is connected, making it possible to extend or reduce the height of said mast by means of removable extensions extending between them and inside the main mast and the receiving faces of which the rollers of the bucket grout are profiled with the faces of said main mast.
D'autres caractéristiques et avantages de la présente addition ressortiront plus clairement de la description qui va suivre faite en regard des dessins joints donnes à titre d'exemple non limitatif, où
- la figure 1 est une vue en perspective d'un coulisseau,
- la figure 2, une ralonge du mat principal et une tête de mat
Tel que représenté figure 1, le coulis seau 16 comporte en ses extrémités 1 et 2 un galet 3 tournant sur son axe 4 dote en ses extrémités de filetage 5 permettant son maintien au moyen d'écrous 6 sur les faces latérales 7 du coulisseau 16, les extrémités 1 et 2 étant celles où sont appliquées les forces dues à la charge de sorte à faciliter son déplacement sur le mat 8.Other characteristics and advantages of the present addition will emerge more clearly from the description which follows, given with regard to the attached drawings given by way of non-limiting example, where
FIG. 1 is a perspective view of a slide,
- Figure 2, an extension of the main mast and a mast head
As shown in FIG. 1, the bucket grout 16 has at its ends 1 and 2 a roller 3 rotating on its axis 4 endowed with its thread ends 5 allowing its retention by means of nuts 6 on the lateral faces 7 of the slider 16, the ends 1 and 2 being those where the forces due to the load are applied so as to facilitate its movement on the mast 8.
Comme représenté figure 2, le mat 8 en son extrémité supérieure peut être prolongé d'une ou plusieurs ralonges 9, chaque ralonge 9 dont la section correspond à celle du mit 8 est pourvue en sa partie inférieure d'un prolongement 10 rapporté ou usiné de section permettant son emboftement sur toute sa longueur et en partie supérieure 11 du mat 8 ou 12 de la ralonge précédente 9, à l'inte- rieur de la section dudit mat 8 ou ralonge précédente 9, en partie supérieure 12 de la ralonge 9 ou en partie superieure 11 du mat 8 peut s'emboîter la tête de mat 13 dotée des éléments nécessaires pour l'årrimage du câble 14 de l'appareil de traction, ladite tête de mat 13 étant dotéed'un prolongement 15 de longueur appropriééet de section permettant son emboftement à l'intérieur de la partie supérieure 11 ou 12 du mat 8 ou ralonge 9. Afin de pouvoir immobiliser les ralonges 9 entre elles et/ou sur le mat 8 ainsi que la tête de mât 13, des évidements 17 sont aménagés sur les ralonges 9 et mât 8 à une distance correspondant-e à celle des évidements 18 aménagés sur les prolongements 10 et 15 afin de permettre ladite immobilisation par tous moyens appropriés tels que broches par exemple. As shown in Figure 2, the mat 8 at its upper end can be extended by one or more extensions 9, each extension 9 whose section corresponds to that of the mit 8 is provided in its lower part with an extension 10 added or machined from section allowing it to be fitted over its entire length and in the upper part 11 of the mast 8 or 12 of the preceding extension 9, inside the section of said mast 8 or preceding extension 9, in the upper part 12 of the extension 9 or in the upper part 11 of the mast 8 can be fitted into the mast head 13 provided with the elements necessary for stowing the cable 14 of the traction device, said mast head 13 being provided with an extension 15 of suitable length and section allowing its nesting inside the upper part 11 or 12 of the mast 8 or extension 9. In order to be able to immobilize the extensions 9 between them and / or on the mast 8 as well as the mast head 13, recesses 17 are arranged on extensions 9 and mast 8 to one distance corresponding to that of the recesses 18 arranged on the extensions 10 and 15 in order to allow said immobilization by any appropriate means such as pins for example.
