Definitions

  • the invention relates to a quick-change device for attachments to be moved on the mast of a carrier vehicle.
  • an adapter for front loader attachments is known, with which a tool, such as a shovel or fork, can be coupled to a vehicle body.
  • the adapter can be used for coupling tools of various types and sizes.
  • the adapter includes side brackets and a middle bracket which are rigidly connected to each other by a support frame and are rotatably connected in a straight line with a pair of lifting arms and a rotating arm protruding from the vehicle body. Disadvantages of this adapter are essentially seen in the fact that the use of diverse components creates a relatively complex construction, which ultimately results in a not inconsiderable increase in weight.
  • the goal underlying the subject matter of the invention is seen in a weight reduction compared to the St.d.T. to design a quick-change device that is as simple as possible, the essential actuating elements of which are provided in a protected form.
  • a quick-change device for attachments to be relocated to the lifting frame of a carrier vehicle in such a way that the lifting frame is formed from two essentially parallel lifting arms, one end of which is mounted on the carrier vehicle and the other ends of which are designed as traverses
  • the lifting frame is formed from two essentially parallel lifting arms, one end of which is mounted on the carrier vehicle and the other ends of which are designed as traverses
  • the free end of which can be connected to elements of the respective attachment and, in the area of its extension, interacts with at least one articulated tie rod, which in turn is connected to other components provided in the area of the mast, and the Locking device for locking the mast on the respective attachment is provided within the hollow body.
  • the pair of tie rod links can be arranged near the tie rod, it being easy to see for the driver of the carrier vehicle during the changing process.
  • the locking mechanism is actuated hydraulically, and the necessary hydraulic lines can be permanently installed at the transition of the mast into the area of the quick-change device, since the traverse does not perform any relative movement.
  • the locking cylinder, the locking bolts and the guides and seals that interact with them are arranged absolutely protected inside the crossmember and are therefore no longer exposed to the soiling or damage that normally occurs.
  • FIG. 1 shows the mast 1 together with a shovel-shaped attachment 2 of a carrier vehicle, not shown.
  • the lifting frame 1 is formed from two lifting arms 3, which are arranged essentially parallel to one another, one ends of which are mounted on the carrier vehicle (not shown).
  • the other ends 4 take a tubular cross member 5 between them, which is shown in more detail in FIG.
  • a pair of tie rod links 6, which is provided in the region of its free end 7 with bolt-shaped lugs 8, which engage in corresponding eyes 9 of the shovel-shaped attachment 2, acts on the tubular crossbeam 5.
  • a tie rod 10 is articulated between the tie rod pair 6, which is connected to a further lever 11, at the free end of which a cylinder (tilt cylinder), not shown, acts.
  • This lever 11 in turn has a pivot point 12 which is mounted via a further lever 13 between the lifting arms 3 of the mast 1.
  • the cross member 5 is stationary in the axis of rotation 14 of the attachment 2, i.e. not rotatable, arranged.
  • Figure 2 shows a partial view of the mast 1 with the lifting arms 3, the pair of tie rods 6, the crossbar 5, the link 10, the bolt-shaped lugs 8 and the levers 11 and 13. Furthermore, the bearing area 15, on which the mast 1 with the carrier vehicle, not shown, can be connected.
  • Figure 3 shows a partial representation of the tubular crossmember 5, which is equipped in its inner region 16 with the following components: a locking cylinder 17, locking bolts 18,19, piston rods 20,21, guides 22,23 for the locking bolts 18,19 and O-rings 24, 25, 26, 27 as sealing elements between the guides 22, 23 and the locking bolts 18, 19.
  • the locking bolts 18, 19 are in the area their free ends 28, 29 are chamfered, in order to be easier to insert into the corresponding recesses of the respective attachment 2 in this way.
  • two bearing areas 31, 32 are provided approximately halfway up, which serve to accommodate the pair of tension links 6.
  • the crossmember 5 is provided in the axis of rotation 14 of the attachment 2 (not shown further here), but the crossmember 5 cannot be rotated. Accordingly, the hydraulic connection 33 can also be provided stationary at a specific point 34 of the crossmember 5.
  • the hydraulic lines 35 and 36 for supplying the corresponding pressure medium are indicated.
