Abstract
Description
La présente invention a trait à un perfectionnement aux dispositifs de levage par treuil a câble, du type comprenant au moins une poulie entre la charge et ledit treuil ; elle concerne également un engin de levage et de manipulation de bordures de trottoirs notamment, appelé couramment pose-bordures, et qui est muni d'un tel dispositif de levage. The present invention relates to an improvement to lifting devices by cable winch, of the type comprising at least one pulley between the load and said winch; it also relates to a machine for lifting and handling curbs in particular, commonly known as curb laying, and which is provided with such a lifting device.
Les pose-bordures classiques sont généralement en forme de potence, constitues d'une poutre s'etendant sensiblement horizontalement a partir de l'extremite d'un mât servant d'embase. La poutre, en porte- -faux, supporte un treuil electrique de levage dont le cable passe sur une poulie d'extremite et s'retend ensuite verticalement jusqu'a une pince de manipulation. La pince, par exemple autoserrante, est manoeuvree par un operateur à l'aide du câble de traction, pour la prise en charge et la depose de bordures de trottoirs en granit ou en beton par exemple. Conventional edge rests are generally in the form of a gallows, consisting of a beam extending substantially horizontally from the end of a mast serving as a base. The beam, cantilevered, supports an electric hoist, the cable of which passes over an end pulley and then extends vertically up to a gripper. The clamp, for example self-clamping, is maneuvered by an operator using the traction cable, for picking up and removing curbs from granite or concrete for example.
Dans les cas ou le treuil adapte sur le pose-bordures est un treuil tres simple, sans guide-cable, lorsque la pince a depose sa charge, le câble tracteur se détend et il arrive frequemment que des defauts d'enroulement se produisent sur son cylindre de stockage. Ces défauts peuvent provoquer des deteriorations rapides du câble en raison aussi de la grande frequence d'utilisation. In cases where the winch adapted to the edge rest is a very simple winch, without cable guide, when the clamp has deposited its load, the tractor cable relaxes and it frequently happens that winding faults occur on its storage cylinder. These faults can cause rapid deterioration of the cable also due to the high frequency of use.
La présente invention propose un dispositif de levage de conception tres simple qui permet de remédier a cet inconvenient et en conservant un treuil qui ne greve pas le prix de l'appareil. The present invention provides a very simple design lifting device which overcomes this drawback and retaining a winch that does not affect the price of the device.
Ce dispositif de levage par treuil est du type comportant au moins une poulie entre la charge et ledit treuil. This hoist lifting device is of the type comprising at least one pulley between the load and said winch.
Selon l'invention, il comporte des moyens aptes a exercer une tension sur le câble, entre le treuil et la charge, de façon a resorber un mou eventuel dudit câble.According to the invention, it comprises means capable of exerting a tension on the cable, between the winch and the load, so as to absorb any slack of said cable.
Toujours selon l'invention, les moyens de résorption du mou agissent en permanence sur le cable, par gravite. Still according to the invention, the slack resorption means act permanently on the cable, by gravity.
Selon un mode de realisation préféré, le dispositif comporte une poulie fixe aval, montee folle sur un axe sensiblement horizontal, a partir de laquelle le câble qui provient du treuil s'etend verticalement jusqu'a la charge a soulever. Les moyens aptes a résorber le mou du câble sont disposes en amont, entre le treuil et cette poulie aval ; ces moyens consistent en un lest exerçant une traction vers le bas sur le câble. According to a preferred embodiment, the device comprises a downstream fixed pulley, mounted idly on a substantially horizontal axis, from which the cable which comes from the winch extends vertically up to the load to be lifted. The means capable of absorbing the slack in the cable are arranged upstream, between the winch and this downstream pulley; these means consist of a ballast exerting a pull down on the cable.
Selon une autre caracteristique, le lest consiste en une masse sur laquelle sont montes deux flasques latéraux qui supportent une poulie centrale verticale, montee folle sur un axe sensiblement horizontal. According to another characteristic, the ballast consists of a mass on which are mounted two lateral flanges which support a vertical central pulley, mounted idly on a substantially horizontal axis.
Toujours selon l'invention, le dispositif de levage est constitue d'un châssis qui supporte le treuil et a l'extremite duquel sont prevus deux flasques lateraux fixes qui supportent une poulie amont, montée folle et la poulie aval. Le lest tendeur de câble est dispose entre ces deux poulies amont et aval ; le câble passe par-dessus les poulies fixes et pardessous la poulie centrale mobile du lest
Selon une autre disposition de l'invention, le dispositif comporte des moyens formant butée et permettant de stopper la course du lest, vers le haut, avant que le câble se tende sensiblement horizontalement entre les deux poulies fixes.Still according to the invention, the lifting device consists of a frame which supports the winch and at the end of which are provided two fixed lateral flanges which support an upstream pulley, idle mounted and the downstream pulley. The cable tensioner ballast is placed between these two upstream and downstream pulleys; the cable passes over the fixed pulleys and below the mobile central ballast pulley
According to another arrangement of the invention, the device comprises means forming an abutment and making it possible to stop the travel of the ballast, upwards, before the cable stretches substantially horizontally between the two fixed pulleys.
cette butee place le dispositif de tension en position inactive.this stop places the tensioning device in the inactive position.
De façon avantageuse, la butee est realisee par les flasques lateraux fixes des poulies amont et aval. Ces flasques comportent une échancrure correspondant a la forme supérieure des flasques lateraux de la poulie mobile ; ces derniers viennent se loger dans ladite echancrure en position inactive du systeme de tension, par exemple lorsqu'une charge est portee. Advantageously, the stop is achieved by the fixed lateral flanges of the upstream and downstream pulleys. These flanges have a notch corresponding to the upper shape of the lateral flanges of the movable pulley; the latter are housed in said indentation in the inactive position of the tensioning system, for example when a load is carried.
L'invention concerne egalement un pose-bordures constitue d'un mât a partir duquel s'etend au moins une poutre qui supporte le treuil de levage. Ce pose-bordures comporte un dispositif de levage muni d'un systeme tendeur de câble tel que defini ci-avant. The invention also relates to a trimmer consisting of a mast from which extends at least one beam which supports the lifting winch. This edge setter comprises a lifting device provided with a cable tensioning system as defined above.
Les caracteristiques definies ci-avant permettent de concevoir un dispositif de levage susceptible d'être adapté sur un pose-bordures pour en faciliter l'utilisation. De telles dispositions limitent les interventions et depannages au niveau du treuil, le câble etant en permanence enroule de façon correcte ; elles augmentent egalement la securite pour les operateurs chargés de travailler avec ce type de matériel. The characteristics defined above make it possible to design a lifting device capable of being adapted to a trimmer to facilitate its use. Such provisions limit interventions and repairs at the level of the winch, the cable being permanently wound correctly; they also increase safety for operators responsible for working with this type of equipment.
Mais l'invention sera encore illustree, sans être aucunement limitée, par la description suivante d'un mode de realisation particulier, donne a titre d'exemple et représenté sur les dessins annexés dans lesquels - la figure 1 est une vue d'ensemble, en perspective, du dispositif de levage selon l'invention, adapté sur un pose-bordures - les figures 2 et 3 montrent respectivement les positions inactive et active des moyens tendeurs de câble. But the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given by way of example and represented in the appended drawings in which - FIG. 1 is an overall view, in perspective, of the lifting device according to the invention, adapted on a trimmer - Figures 2 and 3 respectively show the inactive and active positions of the cable tensioning means.
Tel qu'on l'a represente sur la figure 1, le dispositif de levage selon l'invention peut être adapte sur un pose-bordures 1, pour faciliter la manipulation d'une pince 2, simplement schematisee. As shown in FIG. 1, the lifting device according to the invention can be adapted on a trimmer 1, to facilitate handling of a clamp 2, simply shown in diagram form.
Ce dispositif de levage est monte sur une poutre 3 en porte- -faux ; il est constitue d'un treuil 4 electrique ou hydraulique, commandant l'enroulement et le déroulement d'un câble 5 destine au support et a la manoeuvre des charges, en l'occurrence par l'intermédiaire de la pince 2. This lifting device is mounted on a beam 3 in cantilever; it is made up of an electric or hydraulic winch 4, controlling the winding and unwinding of a cable 5 intended for supporting and handling loads, in this case by means of the clamp 2.
Entre le treuil 4 et la charge, le câble 5 passe par un ensemble de poulies 6, 7 et 8, montees folles sur des axes horizontaux respectivement 9, 10 et 11 et disposees dans le meme plan vertical. Between the winch 4 and the load, the cable 5 passes through a set of pulleys 6, 7 and 8, mounted idly on horizontal axes 9, 10 and 11 respectively and arranged in the same vertical plane.
Les poulies amont 6 et aval 7 sont fixes et sont montees dans un meme plan horizontal entre deux flasques support 12 et 13 solidarises a l'extremite de la poutre 3. Les deux flasques metalliques 12 et 13 definissent, a l'extremite de la poutre 3, une forme de U en-dessous duquel l'espace est libre. The upstream and downstream 7 pulleys are fixed and are mounted in the same horizontal plane between two support flanges 12 and 13 secured to the end of the beam 3. The two metal flanges 12 and 13 define, at the end of the beam 3, a U shape below which the space is free.
La poulie centrale 8 est disposee entre les poulies amont 6 et aval 7, dans un plan horizontal inferieur, sous les flasques 12 et 13 ; elle est montée entre deux flasques latéraux 14 qui supportent une masse 15. Cet ensemble mobile constitue le lest 16 et sert de moyen de tension par gravite pour resorber un mou eventuel dans le câble 5. The central pulley 8 is disposed between the upstream 6 and downstream pulleys 7, in a lower horizontal plane, under the flanges 12 and 13; it is mounted between two lateral flanges 14 which support a mass 15. This mobile assembly constitutes the ballast 16 and serves as a means of tension by gravity to absorb any slack in the cable 5.
L'ecartement des flasques 14 associes a la poulie 8, correspond sensiblement a l'ecartement des flasques 12 et 13 fixes supérieurs. La partie superieure des flasques 14 presente une forme en pointe qui correspond a la forme des echancrures 17, en V renverse, de la partie inferieure de chaque flasque 12 et 13. Ces echancrures 17 sont destinees a servir de butee au lest 16 pour stopper sa course vers le haut. The spacing of the flanges 14 associated with the pulley 8 corresponds substantially to the spacing of the upper fixed flanges 12 and 13. The upper part of the flanges 14 has a pointed shape which corresponds to the shape of the notches 17, in reverse V, of the lower part of each flange 12 and 13. These notches 17 are intended to serve as a stop for the ballast 16 to stop its race up.
Le câble 5, qui part du treuil 4, passe au-dessus de la poulie fixe amont 6, descend ensuite entre les deux flasques 12 et 13 jusqu'a la poulie centrale mobile 8 au-dessous de laquelle il passe pour remonter vers la poulie fixe aval 7. I1 passe au-dessus de cette poulie 7 pour redescendre ensuite sensiblement verticalement vers la charge a manipuler. The cable 5, which leaves the winch 4, passes over the upstream fixed pulley 6, then descends between the two flanges 12 and 13 to the movable central pulley 8 below which it passes to go up towards the pulley fixed downstream 7. I1 passes over this pulley 7 to then descend substantially vertically towards the load to be handled.
La figure 2 montre le dispositif de levage muni de son systeme tendeur de câble par gravite en position inactive. Figure 2 shows the lifting device with its gravity cable tensioning system in the inactive position.
Dans cette position, le lest 16, constitue de la poulie 8, de ses flasques lateraux 14 et de la masse 15, est a sa hauteur maximum, en butee sur les flasques superieurs 12 et 13. La pointe de chaque flasque 14 est logee dans l'echancrure 17 correspondante. Les trois poulies 6, 7 et 8 sont fixes. In this position, the ballast 16, consisting of the pulley 8, its lateral flanges 14 and the mass 15, is at its maximum height, in abutment on the upper flanges 12 and 13. The tip of each flange 14 is housed in the corresponding notch 17. The three pulleys 6, 7 and 8 are fixed.
Dans ce cas de figure, obtenu lors d'une traction a l'extremité du câble 5, par exemple quand une charge 18 est portée le dispositif de levage fonctionne normalement et le systeme tendeur de câble ne fait que dévier la course dudit câble, sans jouer de rôle au niveau de sa tension. In this case, obtained during a pull at the end of the cable 5, for example when a load 18 is carried, the lifting device operates normally and the cable tensioning system only deflects the travel of said cable, without play a role in his tension.
La libération de la charge d'extrémité 18 peut créer un certain mou dans le câble 5 qui se traduit par une diminution de sa tension en certains points, figure 3. The release of the end load 18 can create a certain slack in the cable 5 which results in a reduction of its tension at certain points, Figure 3.
Cette diminution de tension eventuelle va instantanément être absorbee par le lest 16 qui, par simple gravite, va tirer vers le bas la portion de câble disposee entre les deux poulies fixes 6 et 7, figure 3. L'enroulement progressif du cable sur le treuil permet ensuite de ramener le lest dans sa position inactive,ffigure 2, l'extremite du câble etant generalement associee à une charge de masse suffisante. This possible reduction in tension will instantly be absorbed by the ballast 16 which, by simple gravity, will pull down the portion of cable disposed between the two fixed pulleys 6 and 7, Figure 3. The progressive winding of the cable on the winch then makes it possible to return the ballast to its inactive position, ffigure 2, the end of the cable being generally associated with a sufficient mass load.
Comme on l'a represente figure 1, ce type de dispositif de levage peut avantageusement etre adapte sur un engin 1 du type pose-bordures. Ce pose-bordures peut être constitue d'un mât sensiblement vertical 19 à partir duquel s'étendent en porte- -faux une ou plusieurs poutres 3, 20, articulees autour d'axes verticaux 21, 22 et en porte-à-faux. As shown in FIG. 1, this type of lifting device can advantageously be adapted to a machine 1 of the edge-setting type. This edge rest may be constituted by a substantially vertical mast 19 from which extend one or more beams 3, 20 in cantilever, articulated around vertical axes 21, 22 and in cantilever.
De façon avantageuse, la base du mat 19 peut être solidaire d'une poutre transversale 23 sur laquelle sont soudes deux caissons longitudinaux 24 formant guide et dans chacun desquels peut s'inserer la fourche d'un engin de manutention. Advantageously, the base of the mast 19 can be secured to a transverse beam 23 on which are welded two longitudinal boxes 24 forming a guide and in each of which can be inserted the fork of a handling machine.
Cette caracteristique permet d'utiliser un engin polyvalent et courant pour le deplacement à volonte du pose-bordures.This characteristic makes it possible to use a versatile and current machine for the displacement at will of the poses-edgers.
Les signes de reference inseres apres les caracteristiques techniques mentionnees dans les revendications ont pour seul but de faciliter la comprehension de ces dernieres et n'en limitent aucunement la portee. The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
