Abstract

Hook-type lifting device fitted to agricultural tractors for lifting all types of load. The invention relates to a lifting device having a telescopic column which is actuated by the three point system found on tractors without requiring additional mechanisms or power. This device consists of a telescopic column made up of two or three elements 1 and 2 which are provided with a hollow straight part 6 on which the pin of a triangular element 8 is notched. This triangular element comprises, at its base, an internal pin 13 and an external pin 12 which are positioned in the bottom points of the tractor, and a draw bar coupling 14. The column ends with a lifting hook 15. The device according to the invention is particularly intended for lifting all types of load and to be fitted to the three point device of agricultural tractors.

Description

La présente invention concerne un disoositif élévateur à crochet appliqué à des tracteurs agricoles, notamment pour soulever ou manutentionner tout équipement agricole ou toute charge. The present invention relates to a hook lifting device applied to agricultural tractors, in particular for lifting or handling any agricultural equipment or any load.

I1 est bien connu d'utiliser des dispositifs élévateurs ou des bras articulés de manutention notamment pour palettes, systemes de fauchage ou de broyage de friches ou autres objets, à appliquer à la partie arrière du tracteur. Ces dispositifs comportent principalement des glissières verticales le long desquelles coulisse un chariot équipe des elements de saisie adéquats avec leur utilisation, une autre version dé cas dispositifs est décrite pour l'emploi de deux ou trois parties rectilignes articules entre elles, dont le deploiement de l'ensemble est obtenu par l'action de verins oléohydrauliques ou par des poulies autour desquelles s'enroulent une corde, un câble ou une chaîne reliés à une partie fixe du chassis du dispositif. It is well known to use lifting devices or articulated handling arms, in particular for pallets, mowing systems or crushing fallow land or other objects, to be applied to the rear part of the tractor. These devices mainly comprise vertical slides along which slides a carriage fitted with gripping elements suitable for their use, another version of the device case is described for the use of two or three straight parts articulated together, including the deployment of the he assembly is obtained by the action of oleohydraulic jacks or by pulleys around which a cord, cable or chain is wound connected to a fixed part of the chassis of the device.

Tous ces systèmes nécessitent une energie hydraulique, mécanique ou électrique complementaire à celle fournie par tous les tracteurs agricoles. All these systems require hydraulic, mechanical or electrical energy complementary to that supplied by all agricultural tractors.

Le but de la présente invention est de proposer un dispositif simple n'utilisant aucun mécanisme supplémentaire pour réaliser la fonction de levage ou de manutentionner de charges du domaine agricole ou autre, sans pour celà compliquer la structure ou la construction dudit dispositif et d'un prix relativement réduit. The object of the present invention is to provide a simple device using no additional mechanism to perform the lifting or handling function of agricultural or other loads, without thereby complicating the structure or construction of said device and of a relatively reduced price.

Poyr parvenir à ce but, la présente invention consiste à utiliser le dispositif trois points dont tous les tracteurs sont équipés. Cette invention est caractérisée en ce qu'elle comporte une structure tubulaire (Fig.I) talescopique de deux ou trois alêments coulissants coaxialement par rapport à la première colonne (I), avec un jeu tel, de manière à ce que l'un puisse coulisser par rapport au precèdent. Le dernier des éléments tubulaires (2) est équipé d'une portion légèrement coudée (3) de telle façon à conserver une position adéquate avec l'option choisie du système de saisie de la charge. To achieve this goal, the present invention consists in using the three-point device with which all tractors are fitted. This invention is characterized in that it comprises a tubular structure (Fig.I) talescopic two or three sliding alements coaxially with respect to the first column (I), with such a clearance, so that one can slide from the previous one. The last of the tubular elements (2) is equipped with a slightly angled portion (3) so as to maintain an adequate position with the chosen option of the load entry system.

Le verrouillage du deuxième ou troisième élèment tubulaire est obtenu par un système vis - ecrou (4) anime par une poigne active manuellement. The locking of the second or third tubular element is obtained by a screw-nut system (4) driven by a manually active handle.

Au premier élèment (I) de la structure tubulaire, ancré au troisième point (16)du dispositif trois points du tracteur, est rendu solidaire un étrier (5) de façon à contenir ou tirer la charge à lever. A ce premier élément est rendue solidaire par soudure, sertissage ou colletage une partie rectiligne (6) équipée de:--trous ou d'évidements (7) particylièrement conçus au niveau securite pour recevoir l'axe principal de levage de l'élèment triangulaire (8). La liaison du premier élément (I) au troisième point du tracteur, selon une réalisation concrète, est effectues par un gousset (g) prolongé d'un plat (io) entrant dans le premier liement tubulaire et solidaire de ce dernier par un flasque (II) demi lune soudé.At the first element (I) of the tubular structure, anchored at the third point (16) of the three-point device of the tractor, is made integral a stirrup (5) so as to contain or pull the load to be lifted. To this first element is made integral by welding, crimping or colleting a rectilinear part (6) equipped with: - holes or recesses (7) particularly designed at the safety level to receive the main axis of lifting of the triangular element (8). The connection of the first element (I) to the third point of the tractor, according to a concrete embodiment, is effected by a gusset (g) extended by a plate (io) entering the first tubular connection and integral with the latter by a flange ( II) welded half moon.

L'elèment triangulaire (8) constituant la partie principale du dispositif est composé de deux possibilités de fixation sur le système trois points du tracteur selon les entre-axes et les diamètres d'axes : une possibilité fixation exterieure (12) et l'autre intérieure (13) suivant le type de tracteur. De plus cet élément triangulaire est constitué à sa partie. The triangular element (8) constituting the main part of the device is composed of two possibilities of attachment to the three-point system of the tractor according to the inter-axes and the diameters of axes: one possibility external fixation (12) and the other interior (13) depending on the type of tractor. In addition, this triangular element is made up in its part.

inférieure d'un attelage (I4) du type chape ou boule de façon à réaliser le remorquage des vehicules de transports agricoles ou autres.bottom of a hitch (I4) of the yoke or ball type so as to tow agricultural or other transport vehicles.

Le dispositif faisant l'objet de la présents invention peut ètre appliqué principalement aux tracteurs agricoles, mais aussi à tous véhicules automoteurs équipés d'un dispositif trois points, tels les tracteurs viticoles avec des modifications de caractere pratique qui pourront être apportees à l'invention sans pour celà s'éloigner du principe de base de celle-ci, tel qu'il est énoncé dans les revendications qui suivent.  The device which is the subject of the present invention can be applied mainly to agricultural tractors, but also to all self-propelled vehicles equipped with a three-point device, such as wine-growing tractors with modifications of a practical nature which may be made to the invention. without departing from the basic principle thereof, as stated in the claims which follow.
