Description

La présente invention concerne le domaine des équipements de chantiers de construction, en particulier la construction des engins de levage, notamment des monte-matériaux, et a pour objet un tel monte-matériaux muni d'un entraînement à double sens de traction pour l'équipage mobile.The present invention relates to the field of construction site equipment, in particular the construction of lifting devices, in particular material lifts, and has for its object such a material lift provided with a two-way traction drive for the mobile equipment.

Actuellement, les monte-matériaux existant sont généralement constitués par un mât de guidage vertical ou oblique servant au déplacement d'un équipage mobile ou chariot depuis le sol jusqu'à un lieu d'utilisation. L'entraînement de cet équipage ou chariot est assuré au moyen d'un treuil et d'un ensemble câble et poulies. Dans certains cas, le mât peut être pourvu d'un dispositif dénommé genouillère, qui permet de faire varier la pente de la trajectoire du chariot. Cependant, cette pente ne peut dépasser un angle de 30° par rapport à l'horizontale.Currently, the existing material lifts are generally constituted by a vertical or oblique guide mast used to move a mobile unit or carriage from the ground to a place of use. The training of this crew or trolley is ensured by means of a winch and a cable and pulley assembly. In some cases, the mast may be provided with a device called a knee lifter, which makes it possible to vary the slope of the trajectory of the carriage. However, this slope may not exceed an angle of 30 ° from the horizontal.

Le déplacement en retour du chariot ou équipage mobile, c'est-à-dire du lieu d'utilisation vers le sol, s'effectue sous l'action du poids propre dudit chariot avec un relâchement simultané de la tension du câble du treuil.The return movement of the carriage or mobile assembly, that is to say from the place of use towards the ground, is effected by the action of the self-weight of said carriage with a simultaneous relaxation of the tension of the winch cable.

En outre, les chariots de ces monte-matériaux connus sont obligatoirement équipés de dispositifs parachute servant à bloquer le chariot sur le mât en cas d'absence de tension du câble de levage, notamment en cas de rupture de ce dernier. Ainsi, dans le cas d'une obliquité de la trajectoire inférieure à 30° par rapport à l'horizontale, voire sur un tronçon horizontal, la composante tangentielle des forces dues à la pesanteur diminue d'une manière telle qu'une circulation en retour devient pratiquement impossible, et entraîne un fonctionnement intempestif du dispositif parachute.In addition, the carriages of these material lifts known are necessarily equipped with parachute devices used to block the carriage on the mast in the absence of tension of the lifting cable, in particular in the event of the latter breaking. Thus, in the case of an obliquity of the trajectory less than 30 ° relative to the horizontal, or even on a horizontal section, the tangential component of the forces due to gravity decreases in such a way that a circulation in return becomes practically impossible, and leads to inadvertent operation of the parachute device.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un monte-matériaux essentiellement constitué par un mât de guidage muni d'une ou depluseurs genouillères, par un équipage mobile ou chariot guidé sur le mât et entraîné en déplacement par un ensemble d'entraînement relié à l'équipage au moyen d'un câble, caractérisé en ce que le mât est pourvu à son extrémité terminale d'une traverse avantageusement munie d'une poulie flottante sous l'action de ressorts, en ce que ledit mât est muni à son autre extrémité d'une traverse de même type, en ce que le câble de levage est disposé en une boucle passant par les poulies desdites traverses, et dont les extrémités sont reliées à l'équipage mobile, qui comporte deux points d'attache, ledit câble étant entraîné par un treuil disposé en un point quelconque du mât, et qui peut être du type à coincement-adhérence ou du type à double tambour d'enroulement.It has, in fact, for its object a material hoist essentially constituted by a guide mast provided with one or more knee pads, by a mobile unit or carriage guided on the mast and driven in displacement by a drive assembly connected to the equipment by means of a cable, characterized in that the mast is provided at its terminal end with a cross member advantageously provided with a floating pulley under the action of springs, in that said mast is provided at its other end of a cross member of the same type, in that the lifting cable is arranged in a loop passing through the pulleys of said cross members, and the ends of which are connected to the movable assembly, which comprises two attachment points, said cable being driven by a winch arranged at any point of the mast, and which may be of the wedge-grip type or of the double winding drum type.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale d'un monte-matériaux conforme à l'invention ;
  • la figure 2 est une vue analogue à celle de la figure 1 du monte-matériaux dans une configuration différente ;
  • la figure 3 est une vue en plan du chariot ;
  • la figure 4 est une vue en perspective du treuil, et
  • la figure 5 est une vue analogue à celle de la figure 4 d'une variante de réalisation du treuil.
The invention will be better understood thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a side elevational view of a lift materials according to the invention;
  • Figure 2 is a view similar to that of Figure 1 of the hoist in a different configuration;
  • Figure 3 is a plan view of the carriage;
  • FIG. 4 is a perspective view of the winch, and
  • Figure 5 is a view similar to that of Figure 4 of an alternative embodiment of the winch.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemples, les figures 1 et 2 des dessins annexés, le monte-matériaux, essentiellement constitué par un mât 1 de guidage d'un équipage mobile 3 ou chariot, muni d'une (figure 1) ou de plusieurs genouillères 2 (figure 2), et par un ensemble d'entraînement 4 pour le déplacement de l'équipage mobile 3 au moyen d'un câble 8, est caractérisé en ce qu'à chaque extrémité du mât 1 est prévue une traverse 5, qui est munie d'une poulie de renvoi 6, en ce que le câble de levage 8 est disposé en une boucle, dont les extrémités sont reliées à l'équipage mobile 3 (figure 3), et est entraîné par un treuil 7 du type à coincement-adhérence. Ce treuil 7 est disposé en un point quelconque du mât 1 ; dans ce cas au pied dudit mgt 1.In accordance with the invention, and as shown more particularly, by way of examples, FIGS. 1 and 2 of the appended drawings, the hoist, essentially consisting of a mast 1 for guiding a mobile assembly 3 or trolley, provided with one (Figure 1) or several knee pads 2 (Figure 2), and by a drive assembly 4 for the movement of the mobile assembly 3 by means of a cable 8, is characterized in that each end of the mast 1 is provided a cross 5, which is provided with a deflection pulley 6, in that the lifting cable 8 is arranged in a loop, the ends of which are connected to the moving element 3 (Figure 3 ), and is driven by a winch 7 of the wedge-grip type. This winch 7 is arranged at any point of the mast 1; in this case at the foot of said m g t 1.

Les genouillères 2 permettent une subdivision du mât 1 en plusieurs tronçons disposés entre eux suivant des angles divers.The knee pads 2 allow a subdivision of the mast 1 into several sections arranged between them at various angles.

Les traverses disposées aux extrémités du mât sont munies de poulies coulissantes dans leur support contre l'action de ressorts de rappel. Grâce à ce mode de réalisation, les variations de la longueur développée de la boucle constituée par le câble 8 peuvent facilement être compensées.The crosspieces arranged at the ends of the mast are fitted with sliding pulleys in their support against the action of return springs. Thanks to this embodiment, the variations in the developed length of the loop formed by the cable 8 can easily be compensated.

En outre, selon une autre caractéristique de l'invention, et comme le montre la figure 3, l'équipage mobile 3 est avantageusement pourvu d'un magasin de câble 11 permettant un stockage d'un flot de câble superflu dans une configuration donnée du monte-matériaux, ce câble pouvant être utilisé dans le cas d'un prolongement de la longueur du mât 1.In addition, according to another characteristic of the invention, and as shown in FIG. 3, the mobile assembly 3 is advantageously provided with a cable magazine 11 allowing storage of a superfluous flow of cable in a given configuration of the material lift, this cable can be used in the event of an extension of the length of the mast 1.

Comme indiqué plus haut, l'entraînement de câble 8 par l'ensemble d'entraînement 4 peut être effectué au moyen d'un treuil 7 du type à coincement-adhérence (figure 4), qui entraîne le câble 8 sous l'effet des forces de frottement dans un sens de rotation ou dans un autre.As indicated above, the cable drive 8 by the drive assembly 4 can be carried out by means of a winch 7 of the wedge-grip type (FIG. 4), which drives the cable 8 under the effect of friction forces in one direction of rotation or another.

La figure 5 représente une variante de réalisation du treuil, dans laquelle ce dernier est constitué par deux tambours 12 enroulant chacun un brin du câble 8 en sens opposé.FIG. 5 represents an alternative embodiment of the winch, in which the latter consists of two drums 12 each winding a strand of the cable 8 in opposite directions.

Lors d'un déplacement de l'équipage mobile 3 à partir du sol, ledit équipage 3 suit la trajectoire imposée par le mât 1, dont l'orientation peut varier en fonction du nombre de tronçons délimités par les genouillères 2. Ainsi, cette trajectoire peut devenir horizontale (figure 1), ou encore oblique en sens opposé d'un tronçon à l'autre, par exemple pour le franchissement du faite d'un toit (figure 2).During a movement of the moving assembly 3 from the ground, said assembly 3 follows the trajectory imposed by the mast 1, the orientation of which can vary as a function of the number of sections delimited by the kneepads 2. Thus, this trajectory can become horizontal (Figure 1), or oblique in the opposite direction from one section to another, for example for crossing the roof made (Figure 2).

Pendant les déplacements de montée et ceux horizontaux, le câble 8 tire l'équipage mobile 3 au niveau de son point d'attache 9, et lors du franchissement d'une genouillère 2, au cours duquel la longueur de la boucle formée par le câble 8 diminue, la poulie 6 située sous l'équipage mobile 3 se déplace dans son support contre l'action des ressorts de rappel afin de compenser ce raccourcissement temporaire, la poulie opposée comprimant totalement les ressorts sous l'effet de la tension du câble due à la charge contenue dans l'équipage mobile 3. Après le franchissement de la genouillère 2, les ressorts de rappel ramènent ladite poulie 6 à sa position de départ.During the upward and horizontal displacements, the cable 8 pulls the mobile assembly 3 at its point of attachment 9, and when crossing a toggle joint 2, during which the length of the loop formed by the cable 8 decreases, the pulley 6 located under the moving assembly 3 moves in its support against the action of the return springs in order to compensate for this temporary shortening, the opposite pulley completely compressing the springs under the effect of the cable tension due to the load contained in the moving element 3. After crossing the toggle joint 2, the return springs return said pulley 6 to its starting position.

Dans le cas d'un déplacement de l'équipage 3 sur un tronçon du mât 1 incliné en sens inverse (figure 2), le brin du câble 8 fixé au point 10 sert à retenir l'équipage 3 et à contrôler sa vitesse en la faisant correspondre à celle de l'ensemble d'entraînement 4.In the case of movement of the crew 3 on a section of the mast 1 inclined in the opposite direction (FIG. 2), the strand of the cable 8 fixed at point 10 serves to retain the equipment. ge 3 and control its speed by matching it to that of the drive assembly 4.

Lors d'un mouvement inverse, c'est-à-dire de retour de l'équipage 3 vers son point de départ, les conditions de fonctionnement du monte-matériaux sont inchangées, seuls les rôles des brins du câble 8 au niveau de leur point d'attache 9 et 10 sont inversés.During a reverse movement, that is to say return of the crew 3 to its starting point, the operating conditions of the material lift are unchanged, only the roles of the strands of the cable 8 in terms of their attachment point 9 and 10 are reversed.

Par le mode de réalisation conforme à l'invention, il est possible de réaliser un mât 1 présentant un nombre quelconque de tronçons disposés entre eux suivant des angles et des pentes quelconques et reliés par des genouillères.By the embodiment according to the invention, it is possible to produce a mast 1 having any number of sections arranged between them at any angles and slopes and connected by knee pads.

Grâce à l'invention, il est possible de réaliser des monte-matériaux, monte-charges, monorails, ou autres dispositifs à déplacement guidé, présentant un équipage mobile pouvant circuler sur des tronçons de mât d'inclinaisons différentes.Thanks to the invention, it is possible to produce material lifts, freight elevators, monorails, or other devices with guided movement, having a movable assembly able to circulate on mast sections of different inclinations.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques,sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
