Abstract
Description
Die Erfindung betrifft eine Sicherheitsstütze für Hubzylinder gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a safety support for lifting cylinders according to the preamble of claim 1.
Aus dem Stand der Technik ist eine Sicherheitsstütze eines Mähdreschers bekannt, mit der die ausgefahrene Kolbenstange eines Hubrylinders in ihrer Lage zu dem Zylindergehäuse des Hubzylinders festgestellt wird. Die Sicherheitsstütze dient dazu, im Falle eines beispielsweise durch ein Versagen von Hydraulikbauteilen auftretenden Druckabfalls im Hydrauliksystem, ein mit dem Hubzylinder angehobenes Schneidwerk gegen Absinken zu sichern, damit der Bereich unterhalb des Schneidwerks für Reparaturen oder Wartungen des Mähdreschers gefahrlos zugänglich ist. Die Sicherheitsstütze besteht aus einem U-Profil mit stetigem Querschnitt, das am oberen Ende im oberen Gelenkpunkt an der Kolbenstange angelenkt ist und über eine am unteren Ende des U-Profils angeschweißte Kopfplatte auf der Kolbenstange derart aufliegt, dass das U-Profil parallel zur Kolbenstange verläuft. Fährt die Kolbenstange ein, stützt sich die Sicherheitsstütze über die Kopfplatte an dem Zylindergehäuse ab.Out The prior art, a safety support of a combine harvester is known with the the extended piston rod of a lifting cylinder in their position the cylinder housing the lifting cylinder is detected. The safety support is used in the case of, for example, by a failure of hydraulic components occurring pressure drop in the hydraulic system, one with the lifting cylinder Secure raised cutting unit against sinking so that the area below the cutting unit for Repairs or maintenance of the combine safely accessible is. The safety support consists of a U-profile with a constant cross-section, the upper End is hinged in the upper hinge point on the piston rod and a at the lower end of the U-profile welded head plate on the piston rod rests in such a way that the U-profile runs parallel to the piston rod. Drives the Piston rod supports the safety support over the Head plate on the cylinder housing from.
Nachteilig bei dieser bekannten Sicherheitsstütze ist, dass die Sicherheitsstütze an einen bestimmten Hubzylinder angepasst ist und daher nicht universeller einsetzbar ist.adversely in this known safety support is that the safety support to a certain lifting cylinder is adapted and therefore not universal can be used.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Sicherheitsstütze zu schaffen, die die Nachteile des Standes der Technik vermeidet und insbesondere bei unterschiedlichen Hubzylindertypen eingesetzt werden kann.Of the Invention is therefore an object of the invention to provide a safety support, which avoids the disadvantages of the prior art and in particular can be used with different Hubzylindertypen.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Wirkungen des Erfindungsgegenstandes ergeben sich aus den Unteransprüchen.These The object is achieved by the characterizing features of claim 1 solved. Further advantageous effects of the subject invention will become apparent from the dependent claims.
Dadurch, dass die Sicherheitsstütze an den Hubzylinder anpassbar ist, kann das U-Profil der Sicherheitsstütze für mehrere Hubzylinder, deren Kolbenstangendurchmesser unterschiedlich sind, verwendet werden, wodurch die Vielzahl der unterschiedlichen, zu bevorratenden Sicherheitsstützen reduziert werden kann.Thereby, that the safety support can be adapted to the lifting cylinder, the U-profile of the safety support for several Lifting cylinders whose piston rod diameters are different, be used, thereby increasing the variety of different, too stockpiled safety posts reduced can be.
Eine einfache und daher kostengünstige Ausführung der erfindungsgemäßen Sicherheitsstütze ergibt sich, wenn die Sicherheitsstütze im wesentlichen aus einem Grundkörper und einer austauschbaren Kopfplatte besteht und die Anpassung der Sicherheitsstütze auf den Austausch der Kopfplatte beschränkt.A simple and therefore inexpensive execution of safety support according to the invention yourself when the safety support essentially of a basic body and a replaceable top plate and the adaptation of the safety support limited to the replacement of the top plate.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Grundkörper als U-Profil ausgebildet und die Kopfplatte an einem freien Ende stirnseitig an dem U-Profil angeordnet, wobei die Kopfplatte mit wenigstens einer Schraubverbindung mit dem U-Profit lösbar verbunden ist, so dass die benötigte Sicherheitsstütze aus bevorrateten Fertigteilen montierbar ist.In an advantageous embodiment of the invention, the main body as U-shaped profile and the head plate at a free end of the front side arranged on the U-profile, wherein the top plate with at least a screw connection with the U-profit is detachably connected, so that the needed safety support from stockpiled finished parts can be mounted.
Der Mittelpunkt der Querschnittsfläche der Kolbenstange liegt vorteilhafterweise auf dem Schwerpunkt der Querschnittsfläche des U-Profils, damit die auf die Sicherungsstütze wirkenden Druckkräfte kein Biegemoment erzeugen, welches das U-Profil zusätzlich belastet.Of the Center of the cross-sectional area the piston rod is advantageously at the center of gravity of the Cross sectional area of the U-profile, so that the forces acting on the backup support pressure forces no Create bending moment, which additionally loads the U-profile.
Damit die Sicherheitsstützen in Eingriff gebracht werden können, ohne den nicht abgesicherten Bereich unterhalb des abgestützten Maschinenteils zu betreten, ist an der Kopfplatte vorteilhafterweise ein Griff angeordnet.In order to the safety supports can be engaged without the unsecured area below the supported machine part too enter, a handle is advantageously arranged on the top plate.
In einer vorteilhaften Weiterbildung ist die Kopfplatte beidseitig mit dem U-Profil verbindbar, so dass der Griff an der Kopfplatte beidseitig am U-Profil montierbar ist.In an advantageous development, the top plate is on both sides connectable to the U-profile, leaving the handle on the top plate can be mounted on both sides of the U-profile.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist innerhalb des U-Profils ein Anschlag aus Kunststoff angeordnet, indem die Kolbenstange spielfrei geführt wird, damit die Oberfläche der Kolbenstange beim Aufsetzen der Sicherheitsstütze auf der Kolbenstange vor Beschädigungen geschützt wird.In a further advantageous embodiment of the invention is within of the U-profile arranged a plastic stop by the Piston rod guided without play will, so that the surface the piston rod when placing the safety support on the Piston rod from damage is protected.
Dadurch, dass der Anschlag zwischen der Kopfplatte und dem U-Profil geklemmt ist, werden keine zusätzlichen Befestigungsmittel benötigt.Thereby, that the stopper clamped between the top plate and the U-profile is, no extra Fasteners needed.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung, weist die Kopfplatte eine Ausnehmung auf, in der die Kolbenstange angeordnet ist, wobei zwischen Kolbenstange und Kopfplatte ein Spalt verbleibt, damit die Kolbenstange verschleißbegünstigend nicht auf der metallischen Kopfplatte aufliegt.In a further advantageous embodiment of the invention, has the head plate has a recess in which the piston rod is arranged is, leaving a gap between piston rod and top plate, so that the piston rod wear-promoting not on the metallic Top plate rests.
Die Schraubverbindungen arretieren die Sicherheitsstütze in ihrer Lage zur Kolbenstange, wenn die Kopfplatte der Sicherheitsstütze an der Stirnfläche des Zylindergehäuses anliegt, so dass die Sicherheitsstütze nicht aus der Sicherungsposition verschwenkt werden kann.The Screw connections lock the safety support in position to the piston rod, when the top plate of the safety support on the end face of the cylinder housing rests so that the safety support does not come out of the secured position can be pivoted.
Weitere vorteilhafte Ausführungen sind Gegenstand weiterer Unteransprüche und werden an Hand eines in mehreren Figuren dargestellten Ausführungsbeispiels beschrieben.Further advantageous embodiments are the subject of further subclaims and are based on a described in several figures embodiment.
