Abstract

This machine, particularly a grader, comprises two blades of inwardly-curved shape (3) and (5). One (3) of the blades is located at the front (2) of the machine (1), as is known per se, and the second blade (5) is located beyond the lateral plane of the machine (1). The second blade (5) comprises a monoblock box structure (11) sliding laterally in order to provide the machine with two parallel work zones (21, 22).

Description

L'invention a trait à un engin de travaux publics, en particulier à une niveleuse. The invention relates to a public works machine, in particular a grader.

On connaît déjà les niveleuses comprenant un châssis robuste d'une certaine longueur, monté sur quatre roues, en général, à pneus et portant vers le milieu de leur longueur une forte lame au profil incurvé, orientable et incurvable. Des dispositifs de support, commandés par un opérateur monté à l'arrière, permettent de déplacer la lame dans les positions les plus diverses et de faire, ainsi, varier, soit la hauteur de la lame au-dessus du sol ; soit l'angle de la lame avec l'axe longitudinal de marche, soit l'angle de la lame avec le sol, dans un plan vertical ; soit l'angle d'attaque de la lame ; soit la translation latérale de la lame par rapport à l'axe longitudinal. Graders are already known comprising a robust chassis of a certain length, mounted on four wheels, in general, with tires and carrying about the middle of their length a strong blade with a curved, orientable and curved profile. Support devices, controlled by an operator mounted at the rear, make it possible to move the blade in the most diverse positions and thus to vary the height of the blade above the ground; either the angle of the blade with the longitudinal walking axis, or the angle of the blade with the ground, in a vertical plane; either the angle of attack of the blade; or the lateral translation of the blade relative to the longitudinal axis.

Toutefois, cet engin de travaux publics ne permet d'effectuer que des travaux situés à l'avant de l'engin et dans son sens de déplacement. However, this public works vehicle only allows work to be carried out at the front of the vehicle and in its direction of travel.

Cet engin ne peut être utilisé lorsqu'il s'agit de niveler et de réaliser des trottoirs, donc des travaux situés latéralement par rapport à son sens de déplacement. This machine can not be used when it comes to leveling and making sidewalks, so works located laterally relative to its direction of movement.

On connaît également, par le brevet français nO 78.27860, un dispositif pour trottoir pour la réalisation du fond de forme et pour la pose d'un revêtement, notamment pour la pose d'enrobés. Ce dispositif comporte un caisson mobile présentant des moyens pour le compactage et la mise à niveau des matériaux choisis, grossièrement répartis sur la longueur de trottoir à réaliser et des moyens pour le déplacement et le guidage du caisson le long du trottoir. Le caisson est constitué de deux demi-caissons coulissant l'un dans l'autre et dont l'écartement est réglé par un vérin dont le cylindre est solidaire de l'une des parois et le piston est solidaire de l'autre paroi.Toutefois, il n'est pas possible de faire coulisser les deux demi-caissons pour leur emboîtement car les enrobés se sont déposés sur les faces s'interpénétrant et empêchent ledit coulissement. Also known, from French patent No. 78.27860, is a sidewalk device for producing the form bottom and for laying a covering, in particular for laying asphalt. This device comprises a mobile box having means for compacting and leveling the chosen materials, roughly distributed over the length of the sidewalk to be produced and means for moving and guiding the box along the sidewalk. The box consists of two half-boxes sliding one inside the other and whose spacing is adjusted by a jack whose cylinder is secured to one of the walls and the piston is secured to the other wall. , it is not possible to slide the two half-boxes for their interlocking because the coated materials are deposited on the interlocking faces and prevent said sliding.

La présente invention a pour but de fournir un engin de travaux publics qui permet d'effectuer simultanément deux travaux situés dans deux aires parallèles. The object of the present invention is to provide a public works machine which makes it possible to simultaneously carry out two works located in two parallel areas.

A cet effet, l'invention concerne un engin de travaux publics, en particulier une niveleuse caractérisée en ce qu'elle comporte deux lames à profil incurvé dont l'une est située à l'avant de l'engin, comme connue en soi, et dont l'autre, située au-delà du plan latéral de la ni veleuse, comporte un caisson monobloc coulissant latéralement pour conférer à l'engin deux zones de travaux parallèles. To this end, the invention relates to a public works machine, in particular a grader characterized in that it comprises two blades with curved profile, one of which is located at the front of the machine, as known per se, and the other of which, located beyond the lateral plane of the velor ni, comprises a monobloc box sliding laterally to give the machine two parallel work zones.

L'invention sera bien comprise en se référant à la description suivante faite à titre d'exemple non limitatif et au dessin ci-annexé dans lequel : - la figure 1 est une vue en perspective partielle de la niveleuse conforme à l'invention et, notamment est une vue de la lame latérale en position semi-déployée, - la figure 2 est une vue en perspective partielle de la niveleuse conforme à l'invention et, notamment est une vue de la lame latérale en position déployée. The invention will be better understood by referring to the following description given by way of non-limiting example and to the attached drawing in which: FIG. 1 is a partial perspective view of the grader according to the invention and, in particular is a view of the side blade in the semi-deployed position, - Figure 2 is a partial perspective view of the grader according to the invention and, in particular is a view of the side blade in the deployed position.

On se réfère aux deux figures. We refer to the two figures.

La niveleuse 1, connue en soi, comporte, à sa partie avant 2, une première lame a profil incurvé 3 permettant d'effectuer tous les travaux réalisés par les niveleuses connues. The grader 1, known per se, comprises, at its front part 2, a first blade with a curved profile 3 making it possible to carry out all the work carried out by known graders.

Cette niveleuse 1 comporte, sur son côté latéral 4 et, de préférence sur le côté latéral droit, vu dans le sens d'avance de l'engin, une seconde lame à profil incurvé 5 présentant, sur sa face inférieure 6, un patin 7 glissant sur le dessus 8 de la bordure 9 du trottoir 10. This grader 1 comprises, on its lateral side 4 and, preferably on the right lateral side, seen in the direction of advance of the machine, a second blade with curved profile 5 having, on its lower face 6, a shoe 7 sliding on top 8 of edge 9 of sidewalk 10.

Cette seconde lame 5 sert de support a un caisson monobloc 11. This second blade 5 serves as a support for a one-piece box 11.

Ce caisson monobloc 11 est composé d'une paroi avant 12 et de deux parois latérales 13 maintenues à une distance constante. La face arrière 14 de la paroi avant 12 comporte deux coulisseaux 15, 16 coopérant avec des paliers solidaires de la face avant de la seconde lame 5. A l'arrière, le caisson 11 comporte une glissière 17 coulissant à travers le patin 7.This monobloc box 11 is composed of a front wall 12 and two side walls 13 maintained at a constant distance. The rear face 14 of the front wall 12 comprises two slides 15, 16 cooperating with bearings integral with the front face of the second blade 5. At the rear, the box 11 comprises a slide 17 sliding through the shoe 7.

Cette glissière 17 est soumise à une vibration et permet le compactage des matériaux situés à l'avant du caisson 11. A cet effet, la glissière 17 comporte un vibrateur 18, alimenté par un fluide circulant dans des tuyaux 19, 20 et provenant de la niveleuse 1. Pour éviter que les matériaux se répandent sur la première zone de travail 21, on prévoit une paroi intermédiaire mobile située dans le plan vertical séparant la première zone de travail 21 de la seconde zone de travail 22.This slide 17 is subjected to a vibration and allows the compaction of the materials located at the front of the box 11. For this purpose, the slide 17 comprises a vibrator 18, supplied with a fluid circulating in pipes 19, 20 and coming from the grader 1. To prevent materials from spreading over the first working area 21, a movable intermediate wall is provided situated in the vertical plane separating the first working area 21 from the second working area 22.

La seconde lame 5 est donc située au-delà du plan latéral de la niveleuse 1 par rapport à l'axe longitudinal de l'engin et elle est disposée entre le train avant et le train arrière de la niveleuse 1. The second blade 5 is therefore located beyond the lateral plane of the grader 1 with respect to the longitudinal axis of the machine and it is arranged between the front axle and the rear axle of the grader 1.

Bien que l'invention ait été décrite à propos d'une forme de réalisation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de ma tériaux et de combinaisons de ces divers éléments, sans pour cela s'éloigner du cadre et de l'esprit de l'invention. Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to it in terms of forms, materials and combinations of these various elements, without departing from the scope and spirit of the invention.
