Definitions
- the invention relates to a quick-change device for excavators, with which an attachment (attachment tool) on an excavator boom, e.g. a shovel or the like can be attached with the features of the introductory part of claim 1.
- an attachment attachment tool
- an excavator boom e.g. a shovel or the like
- Quick-change devices with hydraulic locking are known, in which a, for example conical, wedge of the quick-change device using a pressure medium cylinder, preferably a hydraulic cylinder, into a, possibly conical, Mount on the attachment, e.g. the spoon that is pushed.
- a quick change device with a securing element is out the US 5 467 542 A known. In its operative position, this prevents known securing element moving the bolt from the Quick change device out.
- the securing element is a Indicator pin connected to the position of the securing element (and not the latch) by pulling out of the quick-change device protrudes when the securing element is not in the active position is.
- the aim of the invention is to provide a fuse for quick-change devices, which has a simple construction and which is easy to use.
- the safety bolt can be replaced by a spring-loaded pressure cylinder, preferably hydraulic cylinder, be operable.
- a spring-loaded pressure cylinder preferably hydraulic cylinder
- the hydraulic cylinder by a spring is acted upon, its piston rod holding the safety pin can form so loaded that the locking bolt even at one Hydraulic defect does not recede. So this is backup the locking of the quick-change device takes effect automatically.
- the quick-change device The hydraulic circuit holding the locking cylinder can be opened again the quick-change device on the piston rod side acted to pull the bolt back, also used to act on the cylinder for the safety bolt in such a way that the safety bolt is pulled back, the (locking) Wedge backs away and the attachment (spoon) from the quick-change device can be uncoupled.
- the securing bolt which is transverse to the bolt the quick-change device can be pushed back and forth, even with a failure of the locking force (e.g. break of the adjusting spindle for the bolt) cannot withdraw from its active position.
- a failure of the locking force e.g. break of the adjusting spindle for the bolt
- the securing bolt is provided with a tab on a locking pin held in position by means of a folding pin can be.
- the invention is also based on the object, based on a quick-change device with the features of the introductory Parts of claims 13 or 14 to provide a quick-change device, which reliably indicates the position of the bolt.
- FIG. 1 shows a position in which the implement 2 on the quick-change device 1 only by means of the hooks 5 is coupled, the bolt 4 not yet in the receptacle 3 is introduced.
- the position in which the implement 2 with the Quick-change device 1 is coupled, is shown in Fig. 2.
