Definitions

  • the invention relates to a device for attaching attachments to excavator arms with a quick-change device and a mounting plate having the features of the introductory part of claim 1.
  • Such devices which allow the attachment and change of attachments at the free end of an excavator boom, are known.
  • this can be applied to the AT 002 087 U1 , the WO 98/46835 A , the AT 413 1117 B and the AT 008 070 U to get expelled.
  • an attachment is to be defined on the excavator boom, which itself has a hydraulic drive, such as hydraulic hammers or slope spoons, it is necessary to connect the hydraulic lines leading to the hydraulic device on the attachment with the hydraulic lines coming from the excavator, after the attachment at the free end the excavator boom has been attached so that the operation and use of the attachment from the cab of the excavator can be controlled.
  • a hydraulic drive such as hydraulic hammers or slope spoons
  • the invention is based on the object to provide a device of the type mentioned comprising a quick-change device and a mounting plate available, in which the attachment of the hydraulic equipment leading to the attachment when setting an attachment at the free end of a digger boomsätig.
  • a coupling is also provided for the at least one hydraulic line leading to the attachment.
  • This hydraulic clutch is activated (closed) when fixing the attachment plate to the quick-change device connected to the excavator boom.
  • An in Fig. 1 shown device 1 comprises a quick-change device 3, which is arranged at the free end of a (not shown) excavator boom or the like., And one with an attachment, for.
  • a forward and surelyschiebbare latch 7, which are wedge-shaped, and in a correspondingly shaped latch receptacle 9 on the mounting plate 5 can be inserted, and provided on the quick-change device 3 rigid Hooks 11, which engage behind a coupling rod 13 (receiving bolts) on the mounting plate 5, the mounting plate 5 can be fixed to the quick-change device 3.
  • a pressure medium cylinder (locking cylinder 10), preferably a hydraulic cylinder, provided and coupled with the bolts 7.
  • the bolt 7 can by a bolt guide 8 through in their in Fig. 1 shown active position in which they engage in the bolt receptacle 9 on the mounting plate 5 of the attachment, are moved and connect 10 the attachment with the quick-change device 3 safe.
  • Fig. 1 It can be seen that lead to the quick-change device 3 coming from the machine (excavator) hydraulic lines 15, which are connected to a plunger housing 17 of a hydraulic clutch 20. From the plunger housing 17 go out two plunger 19, which carry a connected to the plungers 19 block 21, projecting from this two coupling plug 23 and two guide pins 25.
  • the coupling plugs 23 and the guide pins 25 are opposite, at a block 27 which is attached to the attachment (not shown) supporting mounting plate 5, coupling sleeves 29 are arranged, which are complementary to the coupling plugs 23.
  • two receiving openings 31 are provided for the guide pins 25 in the block 27.
  • FIG. 4 shows, carries the guide pins 25 and the coupling plug 23 bearing (slidably mounted on the quick-change device 3) block 21 a through a slot 33 in the side wall 35 of the housing of the quick-change device 3, in which the latch 7 are displaceable, cross-connecting rod 37, the is connected to one of the latch 7. This ensures that the forward or backward sliding of the latch 7, the coupling plug 23 and the guide pins 25 are also pushed back and forth.
  • Fig. 5 shows a variant of the hydraulic clutch 20 of Fig. 2 to 4 in which only one guide pin 25 is provided.
  • hydraulic couplings 20 between coming from the machine (excavator) hydraulic lines 15 and to the attachment, z. B. the hydraulic hammer, leading hydraulic lines 16 are provided on both (longitudinal) sides of the device 1, as shown in Fig. 1 and 9 is indicated.
  • Fig. 6 is attached to the excavator boom quick-change device 3 of the device 1 according to the invention, with the arranged on the quick-change device 3 parts of the hydraulic couplings 20, omitting components again shown in an oblique view. It can be seen that provided on the quick-change device 3 Bar guide 8 continuously open, that is formed without a central web. The bolt receptacle 9 on the mounting plate 5 is open, that is formed without a central web.
  • hydraulic coupling 40 is for the actuation of the hydraulic coupling 40 between the machine (excavator) to the quick-change device 3 leading hydraulic lines 41 and hydraulic lines 43 to the attachment, z.
  • a separate clutch cylinder 45 is provided as a slope ladle lead.
  • first of the latch 7 actuated locking cylinder 10 of the quick-change device 3 is acted upon by hydraulic medium to extend the latch 7 and the bolt 7, so that the mounting plate 5 of the implement is coupled to the quick-change device 3.
  • a predetermined pressure for example a pressure of 120 bar
  • hydraulic pressure is applied to the clutch cylinder 45 via a pressure follower valve.
  • the piston rod 47 of the clutch cylinder 45 extends and provides the connection between the coupling plugs 23, which are fixed to the piston rod 47 of the clutch cylinder via a block 49, and coupling sleeves 29, which are arranged on a, mounted on the mounting plate 5 block 51 ago ,
  • the block 51 with the coupling sleeves 29 is arranged engaging in fixed to the quick-change device 3 mounting plate 5 in the bolt receptacle 9 on the mounting plate 5.
  • From the coupling plug 23 carrying block 49 are in the exemplary embodiment of two guide pins 25 from which engage in closed hydraulic coupling 40 in guide holes 31 in which the coupling sleeves 29 bearing block 51.
  • the block 51 with the coupling sleeves 29 is attached to the mounting plate 5.
  • the device 1 is after closing the hydraulic clutch 40 in the embodiment of the device according to the Fig. 7 to 9 after closing the hydraulic clutch 40 under the action of the clutch cylinder 45 via a 6/2 way valve 55 which is electromagnetically controlled, the hydraulic circuit to the cylinder of the slope tray redirected.
  • the device according to the invention attachments without its own hydraulic drive, as is provided in hydraulic hammers or slope spoons, is used, it is provided that 23 are placed on the provided on the quick-change device 3 coupling plug protective elements.
  • Such protective elements can be arranged on the attachment plate 3 where, in the exemplary embodiment shown, the blocks 27 and 51 are arranged with coupling sleeves 29.
  • a device 1 for connecting attachments with an excavator boom consisting of a mounted on the excavator boom quick-change device 3 and attached to the attachment mounting plate 5 is at least one coupling 20, 40 for connecting coming from the excavator hydraulic lines 15 with hydraulic lines 16 to a drive motor (Hydraulic cylinder) in the attachment.
  • the at least one hydraulic clutch 20, 40 is either coupled to the provided in the locking device 3 bars 7 or is actuated by a clutch cylinder 45 after the locking cylinder 10 has advanced the latch 7 in its operative position.
