Abstract
Description
Die Erfindung betrifft einen Schlagbaum-Wellenantrieb mit einem in einer oberen Position des Schlagbaumes eine Rücktriebskraft erzeugenden Federelement.The The invention relates to a barrier-wave drive with a in one upper position of the barrier tree a return force generating spring element.
Ein
gattungsbildender Schlagbaum-Wellenantrieb ist aus der
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Schlagbaum-Wellenantrieb anzugeben, dessen Federelement vor Ort leicht austauschbar ist.Of the Invention has for its object to provide a generic barrier boom shaft drive, whose spring element is easily replaceable on site.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Federelement einen Parallelogrammrahmen aufweist, der einen ersten U-förmigen Bügel, welcher mit einem Mitnehmer des Schlagbaumes zusammenwirkt, einen zweiten U-förmigen Bügel, welcher mit einem Gehäuse ortsfest verbunden ist, und zwei die Bügelenden über erste Drehgelenke verbindende parallele Hebel aufweist, wobei zwischen den Hebeln mittels zweier mit den Hebeln verbundener zweiter Drehgelenke mindestens eine Feder angeordnet ist, die in der oberen Position gespannt ist.According to the invention Task solved by that the spring element has a parallelogram frame, the one first U-shaped bracket, which interacts with a driver of the turnpike, a second U-shaped Hanger, which with a housing is stationarily connected, and two connecting the strap ends via first pivot joints having parallel levers, wherein between the levers by means of two at least one spring connected to the levers second rotary joints is arranged, which is stretched in the upper position.
Passungsrost, der eine Demontage und damit ein Austausch der Baugruppe erschweren oder verhindern könnte, ist bei dieser Baugruppe nicht zu erwarten. Die beiden Hebel und die beiden Bügel sind über die ersten Drehgelenke zu einem Parallelogramm zusammengefügt. Die Hebel stehen in jeder Position des Schlagbaumes parallel zueinander, jedoch lagebedingt mit unterschiedlichem rechtwinkligen Abstand. Aufgrund des unterschiedlichen Abstandes kann die in den zweiten Drehgelenken gelagerte Feder zusammengedrückt, also gespannt, oder entlas tet, also entspannt werden. Beim Öffnen des Schlagbaumes wird der erste U-förmige Bügel mitgenommen und spannt dadurch die zwischen den Hebeln befindliche Feder. Wird der Schlagbaum-Wellenantrieb stromlos, wird eine Haltevorrichtung, beispielsweise eine Magnetbremse, gelöst. Die gespannte Feder drückt den Parallelogrammrahmen auseinander und verschwenkt den Schlagbaum über den Mitnehmer so weit, dass sich der Schlagbaum aus seiner oberen Endlage selbsttätig aufgrund seines Eigengewichtes in die sichere geschlossene Lage absenken kann. Der Parallelogrammrahmen mit zwischengespannter Feder ist eine separate Baugruppe, die vormontierbar ist und vor Ort, beispielsweise im Reparaturfall, problemlos ausgewechselt werden kann.fretting corrosion, which complicate disassembly and thus replacement of the module or could prevent is not expected with this module. The two levers and the two hangers are over the first hinges joined together to form a parallelogram. The Levers are parallel to each other in every position of the barrier However, due to the situation with different right-angled distance. Due to the different distance in the second Pivoted spring compressed, so tense, or discharged, so be relaxed. When opening of the barrier, the first U-shaped bracket is taken and tensioned thereby the spring located between the levers. Will the barrier shaft drive de-energized, a holding device, for example a magnetic brake, is released. The tense spring presses The parallelogram frame apart and pivots the barrier over the Driver so far that the barrier tree from its upper end position automatic due to its own weight in the safe closed position can lower. The parallelogram frame with intermediate spring is a separate assembly that is pre-assembled and on-site, For example, in case of repair, be easily replaced can.
Gemäß Anspruch 2 ist vorgesehen, dass die Feder als zwischen an den Hebeln angelenkten Federtellern angeordnete Schraubenfeder ausgebildet ist. Auch andere Federkonstruktionen sind denkbar, wobei die Schraubenfedervariante aufgrund ihrer Robustheit und langfristig konstanten Federkraft vorteilhaft ist.According to claim 2 it is provided that the spring as articulated between the levers Spring plates arranged coil spring is formed. Others too Spring structures are conceivable, with the coil spring variant due to their robustness and long-term constant spring force is advantageous.
Dabei ist gemäß Anspruch 3 mindestens einer der Federteller mit einer durch die Schraubenfeder axial hindurchragenden Federführung verbunden. Auf diese Weise ergibt sich eine hervorragende Stabilität des Gesamtsystems.there is according to claim 3 at least one of the spring plate with a through the coil spring axially projecting spring guide connected. This results in excellent stability of the overall system.
Bei einer besonders vorteilhaften Ausführungsform gemäß Anspruch 4 ist vorgesehen, dass mindestens eines der zweiten Drehgelenke an verschiedenen Stellen des Hebels montierbar ist. Dadurch kann die Kraftwirkung der Feder angepasst werden. Eine ältere, quasi ausgeleierte Feder kann weiter verwendet werden, indem eine Schräglage der Feder relativ zu den parallelen Bügeln verringert wird, so dass die Feder in der oberen Position des Schlagbaumes noch stärker zusammengedrückt wird.at a particularly advantageous embodiment according to claim 4 is provided that at least one of the second pivot joints can be mounted in different places of the lever. This can the force effect of the spring can be adjusted. An older, more or less Depleted spring can be further used by an inclined position of the spring relative to the parallel brackets is reduced, leaving the spring in the upper position of the turnpike even stronger pressed together becomes.
Die Erfindung wird nachfolgend anhand figürlicher Darstellungen näher erläutert. Es zeigen:The The invention will be explained in more detail with reference to figurative representations. It demonstrate:
