On connaît pour le forage des sols destinés aux fondations, l'utilisation de tarières s'adaptant sur l'attelage relevable des tracteurs ou tout autre attelage aménagé sur les véhicules, ainsi que les tarières portables, lesdites tarières sont entraînées en rotation soit au moyen d'un renvoi d'angle couplé à la prise de force des tracteurs ou sont entraînées en rotation au moyen d'un rotor hydraulique ou pneumatique ou au moyen d'un moteur à explosion, ce genre de tarières permet de réaliser des forages de sections circulaires ce qui nécessite pour transformer la section circulaire en section carrée d'intervenir manuellement et ce pour correspondre à certaines normes, cette dite transformation n'est pas toujours réalisée sur toute la hauteur du forage et elle est laborieuse et longue.Known for drilling soil intended for foundations, the use of augers adapting to the lifting coupling of tractors or any other coupling fitted on vehicles, as well as portable augers, said augers are rotated either by means a bevel gearbox coupled to the PTO of the tractors or are driven in rotation by means of a hydraulic or pneumatic rotor or by means of an internal combustion engine, this kind of augers allows drilling of sections circular which requires to transform the circular section into a square section to intervene manually and this to correspond to certain standards, this said transformation is not always carried out over the entire height of the drilling and it is laborious and long.
L'invention a pour but de pallier aux inconvénients précédemment exposés.The invention aims to overcome the drawbacks described above.
L'invention a pour objet un dispositif adaptable aux tarières destinées à forer les sols supportées par l'attelage relevable des tracteurs ou tout autre attelage ou support mobile aménagé sur les véhicules ainsi que sur les tarières portables entraînées en rotation par des moyens mécaniques, ledit dispositif permettant de réaliser des forages de section carrée ou rectangulaire est caractérisé en ce qu'il comporte un chassis parallélépipèdique dont les quatre angles verticaux délimitant la section du trou à réaliser sont des montants en cornières leurs ailes se faisant face deux à deux, ces dernières en partie basse sont reliées entre elles par des traverses horizontales et sont prolongées par des couteaux amovibles, en leur partie supérieure et intermédiairement chaque montant est doté d'entretoises alignées avec les diagonales du chassis permettant de maintenir chacune un support vertical en la partie supérieure duquel est fixé au moins un axe support de roulement et en partie inférieure un collier destiné à enserrer la tige centrale de la tarière. Les roulements solidaires du ou des axes disposés de manière quadrangulaire sont soit enserrés entre deux plateaux circulaires horizontaux dans le cas d'un seul roulement à chaque angle ou dans le cas de deux roulements à chaque angle ces derniers enserrent un plateau circulaire horizontal, le ou les plateaux circulaires en leur centre sont prolongés en partie supérieure par un manchon évidé de section carrée destiné à s'emboîter dans le carré de sortie du boitier d'entraînement de la tarière et en partie inférieure par un axe carré recevant le manchon de la queue de la tarière.The subject of the invention is a device adaptable to augers intended for drilling the soil supported by the lifting hitch of tractors or any other hitch or mobile support fitted on vehicles as well as on portable augers driven in rotation by mechanical means, said device for performing square or rectangular section drilling is characterized in that it comprises a parallelepiped frame whose four vertical angles delimiting the section of the hole to be made are uprights in angles their wings facing two by two, the latter in the lower part are connected to each other by horizontal crosspieces and are extended by removable knives, in their upper part and intermediately each upright has spacers aligned with the diagonals of the chassis allowing each to maintain a vertical support in the upper part of which is fixed at least one bearing support axis and in the lower part a collar intended to enclose the central rod of the auger. The bearings integral with the axis or axes arranged in a quadrangular manner are either sandwiched between two horizontal circular plates in the case of a single bearing at each angle or in the case of two bearings at each angle, the latter enclose a horizontal circular plate, the or the circular plates in their center are extended in the upper part by a hollow sleeve of square section intended to fit into the outlet square of the auger drive unit and in the lower part by a square axis receiving the sleeve of the tail auger.
La surface de roulement concentrique au pourtour du ou des plateaux présente sur chaque face du ou des plateaux des ondulations selon des courbes sinusoïdales, lesdites ondulations ayant pour effet de provoquer durant la rotation de la tarière un mouvement alternatif vertical du chassis afin d'engendrer un effet de tamponnement et cisaillement du sol aux abords du trou lors de la pénétration de la tarière et de ce fait réaliser l'équarissage dudit trou.The concentric rolling surface at the periphery of the plate or plates has on each face of the plate or plates corrugations according to sinusoidal curves, said corrugations having the effect of causing during the rotation of the auger a vertical reciprocating movement of the chassis in order to generate a buffering and shearing effect of the soil around the hole when the auger penetrates and thereby squaring said hole.
D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard des dessins joints données à titre d'exemple non limitatif, où :
- - la figure 1 est un vue en perspective d'un dispositif adaptable à une tarière,
- - la figure 2, une variante de plateau circulaire support de dispositif.
- FIG. 1 is a perspective view of a device adaptable to an auger,
- - Figure 2, a variant of the device support circular plate.
Tel que représenté figure 1, le dispositif adaptable aux tarières comporte un chassis parallélépipèdique 1 dont les quatre angles verticaux délimitant la section du trou à réaliser sont des montants 2 en cornières leurs ailes se faisant face deux à deux, chaque montant 2 en partie basse est relié par une traverse horizontale 3 servant en outre à maintenir la terre lors de la réalisation du forage,cette dernière peut éventuellement constituer un caisson, en partie inférieure 4 des montants 2 des couteaux amovibles 5 prolongent lesdits montants 2, ces derniers présentent une forme évasée par rapport aux faces extérieures des montants 2 et ce de manière à dégager les angles du forage du chassis afin de faciliter sa remontée, pour alléger les efforts de la tarière et favoriser la pénétration du chassis 1 dans le sol, les arêtes tranchantes 5a des couteaux 5 présentent un biais plongeant orienté vers la tangente du trou réalisé par la tarrière correspondant à la face du chassis 1.De sorte à dégager la terre émiettée, sur la partie basse 4 des montants 2 est rapportée une tôle 2b disposée en biais et fixée sur les ailes de chaque montant 2 se prolongeant jusqu'au niveau de la virole supérieure de la tarière.As shown in Figure 1, the device adaptable to augers comprises a parallelepiped frame 1 whose four vertical angles delimiting the section of the hole to be made are
En la partie supérieure 6 et intermédiaire 7 des montants 2 sont rapportées des entretoises 8 alignées avec les diagonales du chassis 1, chaque entretoise 8 est raccordée à un support vertical 9 en la partie supérieure duquel est fixé un axe 10 de roulement 11, sa partie inférieure étant raccordée à un collier circulaire 12 destiné à enserrer la tige centrale 13 de la tarière 14. Chaque roulement 11 est enserré entre deux plateaux horizontaux circulaires et identiques 15, ces derniers sont prolongés en partie supérieure par un manchon 16 évidé recevant l'axe carré du dispositif d'entraînement non représenté, en partie inférieure par un axe carré non représenté recevant le manchon de la queue de la tige centrale 13 de la tarière 14, la zone concentrique au pourtour des plateaux 15 sur laquelle s'appuient les roulements 11, présente des ondulations 17 selon des courbes sinusoïdales identiques alternées sur chaque face des plateaux, le nombre d'ondulations 17 en creux et en sommet est généralement pour chacune au nombre de quatre réparties de manière symétrique, il va de soi qu'il peut être prévu un nombre supérieur d'ondulations, ces dernières étant en nombre multiple de quatre. Lesdites ondulations 17 ont pour fonction lors de l'entraînement en rotation de la tarière 14 de provoquer un mouvement vertical alternatif du chassis 1 de telle sorte que durant la pénétration de la tarière 14 dans le sol ledit mouvement vertical alternatif engendre un effet de tamponnement et cisaillement du sol par les couteaux 5 et de ce fait facilite l'équarissage du trou et la pénétration dudit chassis 1.In the upper part 6 and intermediate 7 of the
Selon la variante représentée figure 2, il est aisé de concevoir pour chaque support vertical 9 la fixation de deux axes 10 recevant chacun un roulement 11, lesdits roulements 11 enserrant un seul plateau circulaire horizontal 18 ce dernier présentant les mêmes prolongements que précédemment décrits ainsi que des ondulations 17 alternées sur chacune de ses faces.According to the variant shown in Figure 2, it is easy to design for each vertical support 9 the fixing of two
Sans sortir du cadre de l'invention, il est possible de réaliser le chassis de manière à pouvoir faire varier l'écartement des faces verticales et ce au moyen des traverses 3 et entretoises 8 grâce à des éléments constitutifs s'assemblant entre eux par boulons et ce de manière connue.Without departing from the scope of the invention, it is possible to produce the chassis so as to be able to vary the spacing of the vertical faces and this by means of
