Abstract

The pivoting base is for an inclined goods hoist used on building sites. The hoist (16) is mounted on a frame (14) fixed to a square frame (3). On each corner of the frame a set of two vertical wheels and one horizontal wheel run along the top, bottom and interior face respectively of a ring (1). The ring is fixed to a base frame (2) comprising the chassis. A blockage stop comprises a clamp screwed through a cross beam and bearing on the inner face of the ring.

Description

La présente invention concerne le domaine des équipe mets de chantier, et a pour objet un dispositif de pivotement, notamment pour monte-matériaux oblique de chantier. The present invention relates to the field of construction site equipment, and has for its object a pivoting device, in particular for oblique site hoists.

Les monte-matériaux de chantier existant actuellement sont généralement constitues par un chariot de manutention des matériaux déplacable depuis le sol jusqu'au lieu d'utilisation des matériaux dans une échelle-guide télescopique au moyen d'un treuil, par l'intermédiaire d'un câble et de poulies. Cette échelle-guide est reliée à sa base par une charnière à un châssis, et est reglable en inclinaison, pour faciliter la mise en place sur le lieu de travail, au moyen d'un cric ou d'un vérin fjxé à articulation sur ledit châssis et sur l'échelle-guide. The currently existing site material hoists are generally constituted by a material handling trolley movable from the ground to the place of use of the materials in a telescopic guide ladder by means of a winch, by means of a cable and pulleys. This guide ladder is connected to its base by a hinge to a chassis, and is adjustable in inclination, to facilitate installation in the workplace, by means of a jack or a jack fixed to articulation on said chassis and on the guide ladder.

Il existe des monte-materiaux dans lesquels 11 ensemble e'chelle-guide-treuil-cric ou vérin est monté sur un plateau tournant solidaire du chåssisO Un tel plateau tournant permet une rotation de l'échelle-guide autour d'un axe vertical, facilitant la mise en place sur le lieu d'utilisation. Cependant, les profiles plats constituant les plateaux tournants existant ne présentent pas une résistance suffisante pour absorber les efforts de basculement se produisant lors du pivotement. De tels efforts ne peuvent actuellement être supportés que par des couronnes d'orientation telles que celles utilisées sur les grues à tour, ou analogues. toutefois, l'adaptation de telles couronnes à des monte-matériaux n'est pas économiquement valable. There are material lifts in which 11 ladder-guide-winch-jack or jack assembly is mounted on a turntable secured to the chassis. Such a turntable allows the guide-ladder to rotate about a vertical axis, facilitating installation at the place of use. However, the flat profiles constituting the existing turntables do not have sufficient strength to absorb the tilting forces occurring during pivoting. Such efforts can currently only be supported by slewing rings such as those used on tower cranes, or the like. however, the adaptation of such crowns to material lifts is not economically viable.

la présente invention a pour but de pallier ces inconvé- nients. The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif de pivotement, notamment pour monte-matériaux oblique de chantier, caractérisé en ce qu'il est essentiellement constitué par un tore solidaire du châssis porteur, par un châssis pivotant carré muni à ses quatre coins d1un dispositif de roulement et de guidage, et par un dispositif de blocage de position du chassies pivotant0
L'invention sera mieux comprise grâce à la description ci-apres, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels la figure 1 est une vue en élévation latérale d'un monte-matériaux muni d'un dispositif de pivotement conforme à l'invention la figure 2 est une vue en plan correspondant à la figure 1, l'échelle-guide étant enlevée la figure 3 est une vue en coupe, à plus grande échelle, montrant le dispositif de roulement et de guidage la figure 4 est une vue partielle en plan correspondant à la figure 3, et la figure 5 est une vue partielle en plan représentant le dispositif de blocage du chassies pivotant.
It has, in fact, for its object a pivoting device, in particular for oblique hoists for building sites, characterized in that it is essentially constituted by a torus integral with the carrying frame, by a square pivoting frame provided at its four corners with a rolling and guiding device, and by a device for locking the swivel chase position0
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a view in side elevation of a material hoist provided with a pivoting device according to the invention Figure 2 is a plan view corresponding to Figure 1, the guide ladder being removed Figure 3 is a sectional view , on a larger scale, showing the rolling and guiding device, FIG. 4 is a partial plan view corresponding to FIG. 3, and FIG. 5 is a partial plan view showing the device for blocking the pivoting chases.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 des dessins annexés, le dispositif de pivotement, notamment pour monte-matériaux, est essentiellement constitué par un tore 1 solidaire du chassis porteur 2, par un chassies pivotant carré 3 muni à ses quatre coins d'un dispositif 4 de roulement et de guidage, et par un dispositif 5 de blocage de position du châssis pivotant 3 (figure 2)o
Chaque dispositif 4 de roulement et de guidage est constitué par un galet horizontal 6 s'appuyant contre la génératrice intérieure du tore 1, par deux galets verticaux 7 stappuyant sur les parties supérieure et inférieure du tore 1, et par un support nervuré 8 fixé au coin du chassis 3 (figures 3 et 4)O
le dispositif 5 de blocage de position du chassies pivotant 3 est également solidaire de ce dernier par l'intermédiaire d'un support 9, et est constitué par un écrou 10 prévu au centre du support 9, et par une tige filetée Il pourvue à son extrémité tournée vers le tore 1 d'un tampon 12, dont la forme épouse celle dudit tore 1, et à son autre extrémité d'un organe de manoeuvre 13 (figure 5).
According to the invention, and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawings, the pivoting device, in particular for material lifts, is essentially constituted by a torus 1 secured to the carrying frame 2, by a square pivoting casing 3 provided at its four corners with a rolling and guiding device 4, and by a device 5 for locking the position of the pivoting chassis 3 (FIG. 2) o
Each rolling and guiding device 4 is constituted by a horizontal roller 6 pressing against the inner generator of the torus 1, by two vertical rollers 7 resting on the upper and lower parts of the torus 1, and by a ribbed support 8 fixed to the chassis corner 3 (figures 3 and 4) O
the device 5 for locking the position of the swiveling casing 3 is also integral with the latter by means of a support 9, and is constituted by a nut 10 provided in the center of the support 9, and by a threaded rod It provided for its end turned towards the torus 1 of a buffer 12, the shape of which matches that of said torus 1, and at its other end of an operating member 13 (FIG. 5).

le chassies pivotant 3 porte, en outre, un treuil de levage 14, un vérin 15 de pivotement de l'échelle-guide 16, et des bras 17 de support de ladite échelle-guide 16o
Lors dlun pivotement autour de son axe vertical, le châssis 3 est toujours maintenu sur le tore 1 au moyen de ses dispositifs 4 de guidage et de roulement, les changements de direction des réactions étant toujours transmis par ltintermé- diaire des galets verticaux 7. Un tel changement de direction des réactions peut notamment se produire lors du passage de la position de travail à la position de transport de ltéchelle- guide 16, ou inversement.Lorsque le châssis 3 et le guideéchelle 16 sont en position de service, ou en position de transport sur route, il est possible de les verrouiller en position par rapport au chassies porteur 2 grâce au dispositif de blocage 5, dont le tampon 12 est alors serré sur le tore 1 au moyen de la tige filetée ilo
le dispositif conforme à l'invention a été décrit à propos d'un monte-matériau, cependant ce dispositif peut égale- ment être appliqué à des grues, à des treuils, ou autres dispositifs pouvant être pivotés.
the swiveling chases 3 further carries a lifting winch 14, a jack 15 for pivoting the guide ladder 16, and arms 17 for supporting said guide ladder 16o
When pivoting about its vertical axis, the chassis 3 is always maintained on the torus 1 by means of its guiding and rolling devices 4, the changes in direction of the reactions being always transmitted by means of the vertical rollers 7. A such a change of direction of the reactions can in particular occur during the transition from the working position to the transport position of the ladder-guide 16, or vice versa. When the chassis 3 and the ladder guide 16 are in the service position, or in the position of transport on road, it is possible to lock them in position relative to the carrier chases 2 thanks to the locking device 5, the buffer 12 of which is then tightened on the torus 1 by means of the threaded rod ilo
the device according to the invention has been described in connection with a material hoist, however this device can also be applied to cranes, winches, or other devices that can be pivoted.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté 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 1 'invention0 Of course, the invention is not limited to the embodiment 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.
