Description
Leitschiene für den oberen, 1,durchhängenden Kettentrum bei Hoch- und Tiefbaggern Die Erfindung betrifft eine Leitschiene für den oberen, durchhängenden Kettentrum bei Hoch- und Tiefbaggern nach Patent 362 033. Guardrail for the upper, 1, sagging chain run in high and deep excavators The invention relates to a guardrail for the upper, sagging chain run in high and deep excavators according to patent 362 033.
Die weitere Ausbildung der Vorrichtung nach dem Hauptpatent besteht darin, daß die beiderseits angeordneten Leitschienen selbsteinstellend gelagert sind und den Kettentrum bei jeder Stellung der Eimerleiter oben und unten umfassen.The further training of the device according to the main patent exists in that the guardrails arranged on both sides are stored in a self-adjusting manner and encompass the chain strand in every position of the bucket ladder at the top and bottom.
Ferner sind diese Leitschienen mit einer oberen Führungsleiste versehen und an ihrem Ein- und Ausläufen von federnd gelagerten Führungsrollen getragen, die an hochgestellten Seiten des an dem Ausleger befestigten rechteckigen Verstrebungsgestelles gleiten.Furthermore, these guardrails are provided with an upper guide rail and carried by spring-mounted guide rollers at their inlet and outlet, those on the raised sides of the rectangular bracing frame attached to the boom slide.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel.The drawing illustrates an embodiment.
Abb. r zeigt den Bagger in Seitenansicht, Abb. 2 und 3 stellen die treue Kettenführang in Ansicht und Schnitt dar.Fig. R shows the excavator in side view, Fig. 2 and 3 show the faithful chain guide in view and section.
Es ist a die Antriebswendetrommel und b die Eimerleiter, an deren Ende die Wendetrommel L1 angeordnet ist; L, ist die öb!ere Leitrolle. dl ist der Eimerkettentrum zwischen der Antriebswendetrommel a und dem unteren Knickpunkt c der Eimerleiter b, d. der Trum zwischen dem Knickpunkt c und der Wendetrommel 1l, d-. der Trum zwischen der Leitrolle h und der oberen Leitrolle L.. Ferner ist der Tram zwischen der oberen Leitrolle h und der Antriebswendetrommel a mit d4 bezeichnet.It is a the drive turning drum and b the bucket ladder, at the end of which the turning drum L1 is arranged; L is the upper leading role. dl is the bucket chain center between the drive turning drum a and the lower kink point c of the bucket ladder b, d. the run between the inflection point c and the turning drum 1l, d-. the strand between the guide roller h and the upper guide roller L .. Furthermore, the tram between the upper guide roller h and the drive reversing drum a is denoted by d4.
Nach der Erfindung sind die beiderseitigen Leitschienen p mit- einer oberen Führungsleiste h versehen und an ihren Ein- und Ausläufen von federnd gelagerten Führungsrollen 1 und m getragen. Die Federn dar Rollen sind mit g bezeichnet. Diese Führungsrollen L und m gleiten an den hochgestellten Seiten it und o des an dem Ausleger befestigten rechteckigen Verstrebungsgesxeljes n, o, t, wodurch sich also die Führungsschiene dem jeweiligen Durchhang des oberen Kettentrums selbsttätig anpassen kann.According to the invention, the guide rails p on both sides are provided with an upper guide strip h and are supported at their inlets and outlets by spring-mounted guide rollers 1 and m. The springs of the rollers are denoted by g. These guide rollers L and m slide on the raised sides it and o of the rectangular bracing structure n, o, t attached to the boom, so that the guide rail can automatically adapt to the respective sag of the upper chain strand.
Hierdurch wird beim Heben der Baggerleiter b der größere Durchhang des Eimerkettentrums d4 unschädlich gemacht und eine sichere, nachgiebige Führung der Kette geschaffen.This creates the greater slack when lifting the excavator ladder b of the bucket chain center d4 rendered harmless and a safe, resilient guide created the chain.
In Abb. 3 bezeichnet f die geraden Messer und g die Kettenglieder. h gibt das Profil der Becher an.In Fig. 3, f denotes the straight blades and g the chain links. h indicates the profile of the cups.
Durch die Erfindung ist es auch bei Eimerketten mit Messern möglich, nach Einstellen des Baggers auf Grabenbaggerung reit wagerechter Baggerleiter zu arbeiten. sowie in die äußerste Grabenstellung herunterzugehen und ,dien Graben zu ziehen. Man kann. also mit dem -für Hochbaggerung .eingestellten Bagger ohne weiteres in. Tiefbaggerung übergehen, wenn die Führung des oberen Kettentrums nur genügend lang ausgebildet ist.With the invention it is also possible with bucket chains with knives, After setting the excavator for trenching, a horizontal excavator ladder rides up to it work. as well as to go down to the furthest position of the trench and the trench to pull. One can. So with the excavator set for high excavation without Skip further in. Deep dredging if the leadership of the upper chain strand is only is sufficiently long.
