Description
Die vorliegende Neuerung betrifft ein Anbaugerät mit hydraulischer Arbeitsausrüstung für hydraulische Baumaschinen nach dem Oberbegriff des Schutzanspruchs 1.The The present invention relates to an attachment with hydraulic working equipment for hydraulic Construction machines according to the preamble of claim 1 protection.
Solche Anbaugeräte können hydraulisch verstellbare Baggerschaufeln oder dergleichen sein. Wenn ein Anbaugerät einer hydraulischen Baumaschine gewechselt werden soll, müssen Verbindungen zwischen Hydraulikleitungen der hydraulischen Baumaschine und Hydraulikleitungen oder Hydraulikschläuche des betreffenden Anbaugeräts gelöst werden. Dazu sind Kupplungen, welche mit Rückschlagventilen ausgerüstet sind vorgesehen, die verhindern sollen, dass Hydrauliköl aus dem Hydraulikkreislauf der Baumaschinen oder aus den Hydraulikölschläuchen des Anbaugeräts austritt. Das heißt, wenn ein Anbaugerät von der hydraulischen Baumaschine abgetrennt wurde, sind dessen Hydraulikschläuche vollständig mit Hydrauliköl gefüllt.Such attachments can hydraulically adjustable excavator buckets or the like. If an attachment a hydraulic construction machine is to be changed, connections must between hydraulic lines of the hydraulic construction machine and hydraulic lines or hydraulic hoses of the relevant attachment be solved. These are couplings, which are equipped with check valves intended to prevent hydraulic oil from the Hydraulic circuit of construction machinery or hydraulic hoses of the attachment exit. That is, if an attachment was separated from the hydraulic construction machine, are the hydraulic hoses Completely with hydraulic oil filled.
Wenn ein solches Anbaugerät z. B. in der prallen Sonne abgestellt wird, kann es zu einer Erwärmung des Hydrauliköls in den Hydraulikschläuchen kommen mit damit einhergehender thermischer Volumenausdehnung des Hydrauliköls. Dies erhöht den Innendruck in den Hydraulikschläuchen des Anbaugeräts, sodass bei einem erneuten Anschließen des Anbauteils an die hydraulische Baumaschine der Ankuppelvorgang wesentlich erschwert wird, da das ausgedehnte Hydrauliköl die Rückschlagventilkupplung stark beaufschlagt.If such an attachment z. B. is turned off in the blazing sun, it can cause a warming of the hydraulic oil in the hydraulic hoses come with associated thermal expansion of the volume Hydraulic oil. This increases the Internal pressure in the hydraulic hoses of the attachment, so that when rejoining the attachment to the hydraulic Construction machine of Ankuppelvorgang is much more difficult, since the extended hydraulic oil the check valve coupling strongly charged.
Der vorliegenden Neuerung liegt die Aufgabe zugrunde ein Anbaugerät mit hydraulischer Arbeitsausrüstung für hydraulische Baumaschinen anzugeben, mit dem ein Druckaufbau in den Hydraulikschläuchen des Anbaugeräts im abgekoppelten Zustand vermieden werden kann.Of the present innovation is based on the object an attachment with hydraulic working equipment for hydraulic Specify construction machinery, with a pressure build-up in the hydraulic hoses of attachment can be avoided in the decoupled state.
Diese Aufgabe wird neuerungsgemäß mit den Merkmalen des Schutzanspruchs 1 gelöst. In den Unteransprüchen sind bevorzugte Ausführungsformen der vorliegenden Neuerung beansprucht.These Task is renewal with the Characteristics of the protection claim 1 solved. In the subclaims are preferred embodiments claimed the present innovation.
Das Einstecken der Kupplungen der Hydraulikschläuche des Anbaugeräts in entsprechende Gegenkupplungsstücke des offenen Hydraulikölbehälters hat ferner den Vorteil, dass die Kupplungen vor Verschmutzung von außen geschützt sind.The Inserting the couplings of the hydraulic hoses of the attachment into appropriate Mating coupling pieces has the open hydraulic oil tank Furthermore, the advantage that the couplings are protected from contamination from the outside.
Im Folgenden wird die Neuerung anhand der Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Darin zeigen:in the The following is the innovation based on the description of an embodiment explained in more detail with reference to the drawing. Show:

Ferner sind auf diese Weise die Kupplungsstücke an den Hydraulikölschläuchen des Anbaugeräts vor Verschmutzung sicher, da diese nicht einfach lose am Anbaugerät herunterhängen und mit Staub oder Schlamm in Kontakt kommen können.Further are in this way the coupling pieces on the hydraulic oil hoses of the attachment safe from contamination, as these do not simply hang loose on the attachment and can come in contact with dust or mud.
Die vorliegende Neuerung wurde anhand eines Ausführungsbeispiels, welches lediglich zur Erläuterung dient, beschrieben. Die Beschreibung ist nicht einschränkend zu verstehen.The This innovation was based on an embodiment which only In order to explain serves, described. The description is not restrictive too understand.
