Description
werden, die beispielsweise um eine vertikale Achse schwenkcn oder statt der Schwenkbewegung eine planparallele Bewegung ausführen sollen. "are, for example, schwenkcn about a vertical axis or instead of the pivoting movement should execute plane-parallel movement. "
V Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist in der Zeichnung schematisch in Seitenansicht dargestellt . V An embodiment of the device according to the invention is shown in the drawing schematically in side view.
F i g. 1 zeigt die Vorrichtung mit einem Deckel in einer horizontalen SchUeßstellung undF i g. 1 shows the device with a cover in a horizontal shooting position and
F i g. 2 die Vorrichtung mit einem hochgeschwenkten Deckel.F i g. 2 the device with a pivoted-up cover.
Auf dem mit 1 bezeichneten Deckel, der um eine horizontale Achse 2 schwenkbar ist, sitzt zu beiden Seiten je ein Lagerbock* in dem ein Zapfen4 gelagert ist. Die Zapfen 4 gehen seitlich von dem Flansch 5 eines Zylinders 6 aus, in dem ein Kolben 7 über eine nicht dargestellte Zufuhrleitung nut Druckluft oder -flüssigkeit beaufschlagt wird. Eine aus dem Zylinder 6 herausgeführte Kolbenstange 8 tragt an lhrem freien Ende eine Rolle 9, die sich über eine kurvcnförmige Führungsbahn 10 bewegt. Die Führungsbahn 10 ist an ihrem unteren Ende mit einem feststehenden Rahmen 11 der abzudeckenden öffnung verbunden. Das nach unten gerichtete Ende der Fuhrungsbahn 10 ist zu einem Anschlag 12 ausgebildet, der die Bewegung der Rolle 9 nach unten begrenzt.On the cover labeled 1, which is pivotable about a horizontal axis 2, sits on both Each side has a bearing block * in which a pin4 is mounted is. The pins 4 extend laterally from the flange 5 of a cylinder 6 in which a piston 7 Via a feed line, not shown, only compressed air or liquid is applied. A piston rod 8 led out of the cylinder 6 carries on your free end of a roller 9, which extends over a curved Guide track 10 moves. The guide track 10 is at its lower end with a fixed Frame 11 connected to the opening to be covered. The downward facing end of the guideway 10 is formed into a stop 12 which limits the movement of the roller 9 downwards.
