Abstract

The invention relates to a device mounted on a back hoe bucket of a hydraulic digger and capable of being mounted on and removed from the driving station. The invention allows the device to fulfil the same movements as the bucket. The device includes a thick steel bar which penetrates into the pipe. The length of the steel bar is such that the pipe cannot tip forwards.

Description

La présente invention a pour objet un dispositif destiné à faciliter la pose de certains tuyaux dans les tranchées
Le dispositif consiste en une peèce amovible s'adaptant sur un godet rétro de pelle hydraulique et pouvant être monté eir démonté par le conducteur sans que ce dernier ait besoin de quitter son poste de pilotage,
E@ temps normal,sur un chantier classiquetel que figuré en I de la planche I'nous avons la pelle mécanique en ,le dernier tuyau posé en T et le tuyau en attente de pose en T.
The present invention relates to a device intended to facilitate the laying of certain pipes in the trenches
The device consists of a removable piece adapting to a backhoe bucket of hydraulic shovel and being able to be mounted and disassembled by the driver without the latter needing to leave his cockpit,
E @ normal time, on a traditional building site such as figured in I of the board I'we have the mechanical shovel in, the last pipe laid in T and the pipe awaiting laying in T.

Un ouvrier se tient généralement en haut de la tranchée pou ceinturer à l'aide d'un cable ou d'une sangle le tuyau T' et accrocher ce cable ou cette sangle au godet de la pelle. Deux ouvriers sont alors utiles aux points A & S de la tranchée pour guider l'emboitement du tube t dans le tube T (le tube ' posé est représenté en tireté à la duite du tube T). A worker generally stands at the top of the trench to belt with a cable or a strap the hose T 'and hang this cable or this strap on the bucket of the shovel. Two workers are then useful at points A & S of the trench to guide the fitting of the tube t into the tube T (the tube 'laid is shown in dashed line with the pick of the tube T).

Généralement c'est l'ouvrier placé en B quitremonte de la tranchée pour ceinturer et accrocher le tuyau '
Avec le présent système, l'ouvrier placé en B devient inu tilde plus, l'ouvrier placé en A voit son role restreint puisqutil n'a plus que trois fonctions qui sont:: --T) Guider le terrassement de la machine,le vérifier et l'affiner --2)Placer le joint sur l'embout du tuyau D' lorsqu'il est descendu dans la tranchée --3)Guider le chauffeur de la pelle pour emboiter T' dans T et ceci sans avoir à toucher ' ce qui est un facteur de sécurité
alassiquement,une pelle hydraulique équipée avec un godet rétro se schématise comme indiqué fig 2. Nous avons:
B : bras de godet G : godet rétro V:Vérin de cavage Z axe & BR< godet.
Generally, it is the worker placed in B who goes up the trench to girdle and hang the pipe '
With the present system, the worker placed in B becomes useless more, the worker placed in A sees his role restricted since he has only three functions which are: --T) Guide the earthwork of the machine, the check and refine it - 2) Place the gasket on the end of the pipe D 'when it is lowered into the trench - 3) Guide the shovel driver to fit T' into T and this without having to touch '' which is a safety factor
alassically, a hydraulic shovel equipped with a backhoe is shown schematically as shown in fig 2. We have:
B: bucket arm G: backhoe bucket V: Duck cylinder Z axis & BR <bucket.

Entre les axes X & Y une biellette destinée à transmettre litai tion de la tige de vérin T au godet,ce qui a pour effet de le faire pivoter autour de son axe Z. Pour éviter les surcharges sur le schéma cette biellette n'est pas représentée,
le pivotement du godet autour de son axe Z a pour résultat de modifier la distance D (fig 2) jusqu'à la rendre négative lorsqu'ekle devient D'
C'est cette modification de D en D' qui permet au chauffeur de la machine, depuis son poste de conduite,de monter sur le godet le dispositif objet de l'invention.
Between the axes X & Y a link intended to transmit litai tion from the cylinder rod T to the bucket, which has the effect of rotating it around its axis Z. To avoid overloads on the diagram, this link is not represented,
the pivoting of the bucket about its axis Z results in modifying the distance D (fig 2) until making it negative when ekle becomes D '
It is this modification from D to D 'which allows the driver of the machine, from his driving position, to mount the device object of the invention on the bucket.

La figure 3 schématise le- godet vu suivant la flèche S de a figure 2 et montre où se fixe le dispositif qui est en fon et baptisé E
Il est remarquable que la distance D représente également la distance verticale entre l'axe de godet et le sol lors que les pointes B' touchent le solO
Lorsque par le pivotement du godet autour de son axe Z La pointe P' s"est transférée-- au point P" (fig 2) il en résult qu'an abaissant l'équipement jusqu'à ce que le godet touche le sol,la distance entre l'axe Z et le sol devient D"c'est dans cette position que le dispositif est montable et démon table,
La figure 4 montre le montage du dispositif sur le godet,
Le godet G,grâce à la distance I)1?t qui peut être diminuée passer sous les parties I du dispositifAu relevage-le dis positif se solidarise avec le godet et suit ses pivotements autour de l'axe Z.
Figure 3 shows schematically the bucket seen along arrow S of Figure 2 and shows where the device is fixed which is in fon and baptized E
It is remarkable that the distance D also represents the vertical distance between the axis of the bucket and the ground when the points B 'touch the ground.
When by the pivoting of the bucket around its axis Z The tip P 's "is transferred - to point P" (fig 2) it results that by lowering the equipment until the bucket touches the ground, the distance between the axis Z and the ground becomes D "it is in this position that the device is mountable and demon table,
FIG. 4 shows the mounting of the device on the bucket,
The bucket G, thanks to the distance I) 1? T which can be reduced pass under the parts I of the device. On lifting, the positive device is secured to the bucket and follows its pivoting around the axis Z.

Le dispositif est composé de deux fortes ferrures dont les parties supérieures s'accrochent dans le godet et dont les parties inférieures sont reliées par une embase permettant au dispositif de rester dans la position de la fig 4 lorsqu'il ntest pas en service.The device is composed of two strong fittings, the upper parts of which hang in the bucket and the lower parts of which are connected by a base allowing the device to remain in the position of FIG. 4 when it is not in service.

Les deux fortes ferrures sont espacées afin de laisser libm passage tout à la fois au bras de godet pour le montage et à la biellette,
Les deux fortes ferrures sont également reliées par une platine porte outilla liaison entre ferrures,platine, embase peut être exécutée boulonnée ou soudée.Toutefois il semble préférable d'utiliser les deux possibilités par mesure de sécurité,
A la fig 6 nous voyons l'outil,qui est en fait une forte barre d'acier,lorqqu'il a pénétré dans le tuyau.Afin que le tuyau reste stable sur l'outil,la partie de tuyau reposant sur l'outil doit correspondre à un poids supérieur à la partie ne reposant pas sur l'outil Pour exemple,en fonction du supplément de poids coté tulipe du tuyau,c'est à di re coté platine il peut être admis un outil de I, 30 ml de long,
A la fig 4 nous voyons sous le godet un crochet. Ce crochet existe sur de -nombreux godets standardeAfin qu il ne puisse venir buter sur la platine,il est prévu sur les fortes ferre res des taquets E destinés justement à éviter d'entrée en but tée > Ce sont les taquets qui butent en laissant un espace ent tre platine et crochet,
Les foRds de godet étant renforcés par plaques d'usure il ett bien évident que les taquets E viennent en contact avec ces plaques et non avec la tôle de fond de godet,
Pour la pose du tuyau, nous disposons de tous les mouvements de l'équipement rétro pour présenter l'embout face à la tulipe du tuyau précédemment posé et pour et pour l'enfoncer dans cette tulipe.
The two strong fittings are spaced in order to allow free passage for both the bucket arm for mounting and the link,
The two strong fittings are also connected by a tool-holder plate connection between fittings, plate, base can be carried out bolted or welded. However it seems preferable to use the two possibilities for safety measure,
In fig 6 we see the tool, which is actually a strong steel bar, when it has entered the pipe, so that the pipe remains stable on the tool, the pipe part resting on the tool must correspond to a weight greater than the part not resting on the tool For example, depending on the additional weight on the tulip side of the pipe, that is to say on the platinum side, a tool of I, 30 ml of long,
In fig 4 we see a hook under the bucket. This hook exists on -numerous standard buckets. In order that it cannot come up against the plate, it is provided on the strong ferrules of the cleats E intended precisely to avoid entering into the goal t> These are the cleats which stop leaving a space between plate and hook,
The bucket bases being reinforced by wear plates it is obvious that the tabs E come into contact with these plates and not with the bottom plate of the bucket,
For the installation of the pipe, we have all the movements of the retro equipment to present the end piece facing the tulip of the pipe previously laid and for and to push it into this tulip.
