Definitions

  • the invention relates to a quick-change device for work tools on an excavator boom, loader arm or the like.
  • Tool holder with a holding frame (4) adjustable on the tool holder, a hook (6) extending from the holding frame, which has a hook jaw (16) and a free back, a stop surface (15) arranged on the holding frame behind the hook, and a locking device (9 ), also with a cross tube (21) attached to the work tool, to which the hook jaw is assigned as a receptacle, a stop plate (22) cooperating with the stop surface, between which and the cross tube an insertion opening is provided, so that the cross tube from the pivoting movement of the holding frame Hook mouth "., The stop surface (15) moves against the stop plate (22) and the locking device can be actuated.
  • a device of the aforementioned type known from GB-A 20 40 262 (BEALES STEEL) has a complicated structure insofar as a larger number of pins and projections with recesses or depressions have to be brought into mutual engagement between the tool carrier and the tool, before the tool can be locked on the tool carrier. If the cross pin of the tool holder are pressed against the tool for the purpose of coupling, there is a risk that the tool will roll away even with slight misalignments. The recording process therefore causes considerable difficulties for the machine operator.
  • the aim of the invention is therefore an improved quick-change system of the type described at the outset, with which the replacement of the work tool is simplified in terms of function and also in terms of the construction required for this, in that fewer interlocking components are necessary.
  • This design both an after the first provisional latching of the hook into the associated receptacle, an automatically subsequent centering engagement until the coupling is complete - and all tool stresses are absorbed into the holding frame and thus into the machine via a single locking element.
  • the simplified structure of the quick-change device according to the invention results from the fact that the hook emanating from the tool carrier not only comprises the cross tube on the tool, but is also equipped on its rear side with the beveled seat surface which, following a certain engagement position of the hook in cooperation with the opposite one Inclined surface of the stop plate of the tool is effective as a support, so that from the outset a statically clear fixation of the quick change direction is achieved if you consider the engagement process with unilateral operating force.
  • the locking pawl known per se which advantageously acts on the other end of the stop plate designed as a counter-locking part, also becomes effective when the mutual engagement conditions are completed.
  • the stop plate is a particularly simple component and, due to its position on the tool holder, contributes decisively to its stiffening and stability.
  • the stability of the receptacle is further promoted by the fact that the receptacle, which consists of two side parts or side plates, is very simple, in addition to the stop plate running transversely thereto, also through the cross tube. are stiffened. This means that the receptacle on the work tool required for the quick-change system does not require any particularly noteworthy changes, because practically the same components are used for the stability of the receptacle, which also serve the stability of the work tool itself.
  • the latch may include an actuator arm between its ends, which contains an opening for receiving a manually operable Steckarms for manually unlocking the pawl, said operating arm of the pawl is disposed opposite to about 18 0 ° the lock arm.
  • the stop arranged in the path of an actuating arm of the pawl can be designed as a hydraulic plunger which is guided in a hydraulic cylinder fastened to the side plate of the holding frame in such a way that it overcomes the pawl spring force when the cylinder is acted upon Pawl pivoted into its unlocked position.
  • a holding frame 4 is fastened to the excavator or loader arm 1 and to an excavator or loader link 2 by means of pivot bolts or other pivot bearings 3a or 3b.
  • the holding frame consists of two side plates 4a, 4b (Fig. 2) which are connected by one or more cross connections, e.g. are connected to each other by a tubular profile 5.
  • the side plates are each designed as hooks 6, which can wrap around a cross tube 21.
  • Each hook 6 has on its inside a corresponding semicircular seat surface 16 for receiving a cross tube 21 seated on the tool.
  • the hooks 6 are provided with an inclined surface 7 which, as can be seen in FIGS. 3 and 4, has a certain section has a straight course.
  • a pawl 9 is pivotally held on an axis 8.
  • the pawl has a first actuating arm 17, on which one or more springs 1o engage in order to pretension it against a stop 11.
  • the bias springs 1o can each on one of the side plates outgoing approach to be supported, and corresponding stops 11 can be attached to the side plates 4a and 4b.
  • the actual pawl has an inclined surface 12, by means of which it can be pivoted when touching a counter bevel 25 on the tool until it reaches an end position which is limited by a second stop 13, this second stop simultaneously serving as a support for the biasing spring 10 serves.
  • the work tool e.g. B. an excavator bucket or a shovel is provided with a receptacle 20 which has two side webs 20a, 20b running parallel to the side parts of the holding frame 4.
  • the side webs are connected to a unit by a cross tube 21 and by a stop plate 22 and are arranged at a distance from one another which is sufficient to accommodate the holding frame 4 therebetween (FIG. 2).
  • the cross tube is arranged according to FIG. 1 with its central axis approximately in the extension of the central plane of the stop plate 22. In the distance between the cross tube 21 and the stop plate 22, the hook 6 of the holding hook hooks mens 4 a.
  • the stop plate 22 also connects the two side webs 20a, 20b and serves at one end 23 as an abutment for the inclined surface 7 of the hook 6.
  • the underside of the holding frame which is designed as a stop surface 15, comes into contact with the upper side 14 of the stop plate 22.
  • the pawl 9 also has the other side 24 of the stop plate 22 provided with the inclined surface 25. In this state, the inclined surface 7 presses the hook 6 onto the cross tube 21 essentially without play.
  • FIG. 3 shows the process of engaging the holding frame and tool holder.
  • the holding frame 4 is hooked into the tool with the hook 6 and there into the opening between the cross tube 21 and the stop plate 22 and pivoted clockwise around the cross tube 21 until the catch 9 engages or has caught the stop plate 22.
  • Fig. 3 shows the time at which the pawl 9 with its inclined surface 12 touches the bevel 25 of the stop plate 22 and is thereby rotated counterclockwise about the axis 8 and the force of the biasing spring 10.
  • the pawl 9 can have a second actuating arm 18 between its ends, which has an opening for receiving a manually operable plug-in arm, with which the pawl is lifted and unlocked manually.
  • the second actuation arm 18 is preferably positioned approximately 180 0 to the lock arm or the hook of the pawl opposite.
  • the process of disengaging is shown in Fig. 4 in more detail.
  • the stop arranged in the path of the first actuating arm 17 of the pawl 9 is designed as a hydraulic plunger 30, which is pressed against the stop 13 while overcoming the force of the biasing spring 10, and then the holding frame 4 is pivoted counterclockwise in accordance with the arrow direction shown.
  • the plunger piston can be guided in a hydraulic cylinder 31 fastened to the side plate of the holding frame 4 such that it pivots the pawl into its unlocked position when the cylinder is acted upon while overcoming the spring force.
  • the oil pressure required to extend the piston 30 can be generated by the machine operator by hand or foot operation. This is preferably done Generating pressure by actuating a foot or hand lever 43 in the manner indicated by oil displacement by means of a small displacement piston 44, so that no additional engine hydraulics are required for this.
  • a particular aspect of the manual decoupling indicated in FIG. 1 is that this process can be carried out safely at any time, since the work tool remains held in place by the cross tube 21 connected to it in the hooks 6 arranged on both side plates of the holding frame 4.
  • the hook 6 is continuously wider from its tip to the connection to the side webs 4a, 4b of the holding frame 4, or, in other words, that at 1, the rays drawn from the center of the cross tube 21 to the rear of the hook 6 become increasingly longer, in particular over the area the rear inclined surface 7 of the hook 6.
