Abstract

The coupling has automatic locks in the form of separate spring-actuated cams (B) acting on the inner or outer walls of an adapter (2) on the bucket. The four ends of the coupling engage with four points on the adapter, applying an evenly distributed thrust which prevents any twisting of the bucket. The cams can be released either manually or by a hydraulic cylinder.

Description

Système, dit " attache rapide", conçu pour le démontage et le remontage de godet de grue ou chargeur sans autre intervention que celle du machiniste.System, called "quick coupler", designed for disassembly and reassembly of crane buckets or loaders without other intervention than that of the machinist.

Ce système existe déjà sous différentes marques.
Cependant, leur fonctionnement travaille différemment, sort les crochets aux adaptions (prise du bac), soit les verrouillages du bac sont faits :

  • par cale,
  • par came placée à différents endroits.
par verrou conique.This system already exists under different brands.
However, their operation works differently, takes out the hooks for adaptations (catch of the tray), or the locks of the tray are made:
  • by hold,
  • by cam placed in different places.
by conical lock.

VERROUILLAGES EXISTANT ACTUELLEMENT SUR LE MARCHELATCHES CURRENTLY EXISTING ON THE MARKET

  • par cale conique, fixée par boulons ou autres.
    Nécessite beaucoup de manipulation pour arriver au résultant demandé.    by conical wedge, fixed by bolts or others.
    Requires a lot of manipulation to arrive at the requested result.
  • par came, (ce système est vieux comme le monde).
    Il est très efficace mais nécessite pour l'installation de l'attache le démontage de la poutre principale de chaque bac existant et les cames placées au centre de l'attache peuvent provoquer une torsion du bac.    by cam, (this system is as old as the world).
    It is very effective but requires for the installation of the fastener the disassembly of the main beam of each existing tank and the cams placed in the center of the fastener can cause a twisting of the tank .
  • par verrou conique, même remarque que pour le système par came.by conical lock, same remark as for the cam system.

Claims (3)

Attache rapide universelle destinée au verrouillage de tous types de bac de grue sur pneus ou sur chenilles.
Elle a pour but de remédier aux inconvénients des systèmes de verrouillage existant actuellement sur le marché.
La présente revendication explique de quelle manière les avantages obtenus grâce à cette invention consistent essentiellement au positionnement des deux cames de blocage placées dans les parois des adaptateurs fixes du bac ce qui évite toute torsion du bac.
La présente invention est exposée ci-après plus en détail, à l'aide d'un dessin représentant un exemple d'exécution standard.
L'attache rapide (1) vient pivoter autour de l'axe (A) de l'adaptateur (voir Figure 1)
Les 2 cames (B) pivotant sur l'axe (5) viennent buter sur les bords profilés (3) des découpes pratiquées sur les parois de l'adaptateur (2) fixé au bac (Voir Figure 1)
Sous l'effet de la force exercée par le cavage (4) (pivotement du vérin fixé à l'extrémité de la flèche de la grue) les 2 cames (B) suivent les bords profilés (3) des découpes de l'adaptateur (2) (Voir Figure 2)
L'axe (5) de pivotement des cames (B) vient se positionner sur les appuis (C) de l'adaptateur (2) (Voir Fig .3)
A l'aide des ressorts (D) les cames (B) exercent une poussée sur les bords profilés des découpes (3) de l'adaptateur (2) et maintiennent l'axe de pivotement (5) sur les appuis (C) (Voir Figure 4 et 5).
Le verrouillage exercé par les cames (B) à l'aide des ressorts (D) permet d'obtenir en supprimant le jeu un serrage maximum entre l'attache rapide (1) et l'adaptateur (2).
Le déverrouillage s'effectue en exerçant un déplacement vers le haut des cames (B) pivotant sur leur axe (5) à l'aide de deux tiges (F) à placer dans le système de verrouillage (E) incorporé aux cames (B) (Voir Figure 4 et 5).Universal quick coupler for locking all types of crane tanks on tires or tracks.
Its purpose is to remedy the drawbacks of the locking systems currently existing on the market.
The present claim explains how the advantages obtained thanks to this invention consist essentially in the positioning of the two locking cams placed in the walls of the fixed adapters of the tray which prevents any twisting of the tray .
The present invention is explained below in more detail, using a drawing representing an example of standard execution.
The quick coupler (1) pivots around the axis (A) of the adapter (see Figure 1)
The 2 cams (B) pivoting on the axis (5) abut on the profiled edges (3) of the cutouts made on the walls of the adapter (2) fixed to the tank (See Figure 1)
Under the effect of the force exerted by the digging (4) (pivoting of the jack fixed to the end of the boom of the crane) the 2 cams (B) follow the profiled edges (3) of the cutouts of the adapter ( 2) (See Figure 2)
The pivot axis (5) of the cams (B) is positioned on the supports (C) of the adapter (2) (See Fig. 3)
With the help of the springs (D) the cams (B) push on the profiled edges of the cutouts (3) of the adapter (2) and maintain the pivot axis (5) on the supports (C) ( See Figure 4 and 5).
The locking exerted by the cams (B) using the springs (D) makes it possible, by eliminating the play, to obtain maximum tightening between the quick coupler (1) and the adapter (2).
Unlocking takes place by exerting an upward movement of the cams (B) pivoting on their axis (5) using two rods (F) to be placed in the locking system (E) incorporated in the cams (B) (See Figure 4 and 5). Attache rapide (1) selon la revendication 1 (Voir Figure 1) pour laquelle l'adaptateur (2) est modifié pour équiper le bac d'un chargeur sur pneus ou sur chenilles.Quick coupler (1) according to claim 1 (See Figure 1) for which the adapter (2) is modified to equip the bin of a wheel or crawler loader. Attache (1) selon les revendications 1 et 2 pour laquelle les cames (B) peuvent aussi bien travailler sur les faces externes ou internes de chaque paroi de l'adaptateur (Voir Figure 5)Attachment (1) according to claims 1 and 2 for which the cams (B) can work on the faces as well external or internal of each wall of the adapter (See Figure 5)
