Abstract
Description
Béquille d'appui de pelle hydraulique du type "araigne. Hydraulic shovel support stand of the spider type.
L'invention se rapporte aux pelles hydrauliques a béquilles d'appui, et a train de roues unique dites pelles waraignée n -
Sur de telles pelles, les béquilles sont montées sur le chassies de façon à être pivotantes en hauteur et en écartement l'une par rapport à l'autre. Elles comportent généralement un patin d'ancrage ou appui sur le sol monté à rotule avec un certain débattement pour s'adapter à la surface du sol en appui horizontal, ce débattement étant toutefois plutôt indésirable quant à la faculté d'agrippage du patin lors d'un travail sur sol incliné.The invention relates to hydraulic shovels with support legs, and a single wheel train called shovel shovels n -
On such shovels, the crutches are mounted on the casing so as to be pivotable in height and in separation from one another. They generally include an anchor pad or support on the ground mounted with ball joint with a certain clearance to adapt to the surface of the ground in horizontal support, this clearance being however rather undesirable as for the grip ability of the pad during '' work on inclined ground.
La présente invention a pour objet un agencement particulier d'une telle béquille, qui permet de satisfaire les conditions souhaitées en travail sur sol horizontal aussi bien que sur sol incliné, sans montage à rotule du patin d'ancrage, et de mieux répartir les efforts engendrés dans une telle béquille. The subject of the present invention is a particular arrangement of such a stand, which makes it possible to satisfy the desired conditions when working on horizontal ground as well as on inclined ground, without ball joint mounting of the anchoring pad, and to better distribute the forces. generated in such a crutch.
Essentiellement, à cet effet, la béquille selon l'invention est caractérisée en ce qu'elle est constituée par deux bielles superposées formant un parallélogramme articulé, d'une part avec une monture articulée sur le châssis pour assurer le mouvement de pivotement transversal précité et, d'autre part, avec une jambe portant a son extrémité inférieure un patin d'appui au sol non articulé par rapport à elle. Une telle béquille est notamment actionnable dans son pivotement en hauteur à l'aide d'un vérin hydraulique, et ce dernier peut être avantageusement interposé entre ladite monture d'articulation et la bielle inférieure du parallélogramme, de sorte qu'il est relativement protégé des atteintes par les deux bielles. Essentially, for this purpose, the stand according to the invention is characterized in that it is constituted by two superimposed connecting rods forming an articulated parallelogram, on the one hand with a frame articulated on the chassis to ensure the aforementioned transverse pivoting movement and , on the other hand, with a leg carrying at its lower end a support pad on the ground not articulated relative to it. Such a stand is in particular operable in its pivoting in height using a hydraulic cylinder, and the latter can advantageously be interposed between said articulation mount and the lower connecting rod of the parallelogram, so that it is relatively protected from reached by the two connecting rods.
En outre, chaque patin d'ancrage peut être monté de façon télescopique dans la jambe qui le porte. In addition, each anchor pad can be mounted telescopically in the leg which carries it.
Une forme de réalisation d'une béquille d'appui de pelle hydraulique selon l'invention est d'ailleurs ci-après décrite a titre d'exemple et en référence au dessin annexé, dont la figure unique est une vue en élévation de côté d'une pelle 'araignée1. An embodiment of a hydraulic shovel support stand according to the invention is also described below by way of example and with reference to the accompanying drawing, the single figure of which is a side elevation view of 'a spade' spider 1.
La pelle représentée comprend une cabine 1 montée par l'intermédiaire d'une plate-forme tournante 2 sur un châssis 3. Le chassis 3 est pourvu d'un train de roues constitué de deux bras porte-roue espacés tels que le bras 4, monté oscillant dans le plan vertical sur un palier 5 transversal au plan de la figure, et réglable angulairement, c'est-a-dire en écartement, par pivotement autour d'un axe 6 porté par le palier 5. La position de chaque bras 4 est assurée dans le plan vertical par l'intermédiaire d 'un vérin 7 prenant appui sur le châssis et de mme en écartement par l'intermédiaire d'un vérin non représenté. The shovel shown comprises a cabin 1 mounted by means of a rotating platform 2 on a chassis 3. The chassis 3 is provided with a set of wheels consisting of two spaced-apart wheel-carrying arms such as the arm 4, mounted oscillating in the vertical plane on a bearing 5 transverse to the plane of the figure, and angularly adjustable, that is to say in spacing, by pivoting about an axis 6 carried by the bearing 5. The position of each arm 4 is provided in the vertical plane by means of a jack 7 bearing on the chassis and likewise in spacing by means of a jack not shown.
A l'opposé des roues, le châssis est pourvu de deux béquilles, telle que celle désignée par 8 dans son ensemble. Opposite the wheels, the chassis is provided with two crutches, such as that designated by 8 as a whole.
Cette béquille est constituée de deux bielles superposées 9 et 10 formant un parallélogramme articulé en hauteur, d'une part avec une monture 11, elle-même articulée sur le châssis suivant un axe 12, permettant un mouvement de pivotement transversal de la béquille. Ce parallélogramme est d'autre part formé avec une jambe 13 qui est pourvue à son extrémité infe- rieure d'un patin ancrage 14 ici solidaire d'elle. Mais ce patin pourrait être aussi monté de façon télescopique dans l'axe de la jambe avec notamment plusieurs positions possibles verrouillables manuellement.This stand consists of two superimposed connecting rods 9 and 10 forming a parallelogram articulated in height, on the one hand with a frame 11, itself articulated on the chassis along an axis 12, allowing a transverse pivoting movement of the stand. This parallelogram is also formed with a leg 13 which is provided at its lower end with an anchoring pad 14 here integral with it. However, this shoe could also be mounted telescopically in the axis of the leg, in particular with several possible positions which can be locked manually.
Une telle béquille est manoeuvrable en hauteur par l'intermédiaire d'un vérin télescopique 15 articulé entre la monture 10 et la bielle inférieure 9 du parallélogramme, dans l'intervalle des deux bielles de façon a être protégé par elles. Such a stand is maneuverable in height by means of a telescopic jack 15 articulated between the frame 10 and the lower link 9 of the parallelogram, in the interval between the two links so as to be protected by them.
On notera qu'avec cet agencement de béquille on ne rencontre aucun problème en position d'appui horizontal désiré par suite de la déformation en parallélogramme de la béquille (voir position en trait plein et trait mixte par exemple) et que le maintien rigide du patin constitue un élément favorable pour son agrippage et sa pénétration sur sol incliné. Le mouvement de pivotement transversal de la béquille est ici aussi assuré par l'intermédiaire d'un vérin télescopique 16, articulé entre un axe 17 du châssis 3 et un axe 18 de la monture 10, qui est excentré par rapport à l'axe 12 de pivotement de cette monture et de la béquille. Bien entendu diverses variantes de réalisation d'une telle béquille peuvent être imaginées sans pour autant sortir du domaine de l'invention. It will be noted that with this stand arrangement there is no problem in the desired horizontal support position as a result of the parallelogram deformation of the stand (see position in solid line and dashed line for example) and that the rigid holding of the shoe constitutes a favorable element for its grip and its penetration on inclined ground. The transverse pivoting movement of the stand is here also ensured by means of a telescopic jack 16, articulated between an axis 17 of the chassis 3 and an axis 18 of the frame 10, which is eccentric relative to the axis 12 pivoting of this mount and the stand. Of course, various variants of such a stand can be imagined without departing from the scope of the invention.
