Description

Schnellspannvorrichtung für Flanschverbindungen mit einem hufeisenförmigen Bügel und einer Spannschraube Die Erfindung geht aus von einer Schnellspannvorrichtung für Flanschverbindungen, welche einen hinter einen der beiden zu verbindenden Flansche seitlich aufschiebbaren, etwa hufeisenförmigen Bügel aufweist, dessen Schenkel etwa in ihrer Mitte je einen die Flansche übergreifenden hakenartigen Ansatz tragen und in dessen Quersteg ein mittels einer Spannschraube auf die Rückseite des einen Flansches anpreßbares bewegliches Widerlager angeordnet ist. Die Anpreßkraft wird bei dieser Vorrichtung entweder mittels einer Schraube oder mittels eines Exzenters erzeugt, dessen Bedienung einen Drehgriff mit großem Hebelarm oder einen Spezialschlüssel erfordert, um das nötige Drehmoment zu erzeugen. Es ist viel Bewegungsraum nötig, um diese bekannte Vorrichtung bedienen zu können, was besonders bei schnell aufgebauten Versuchseinrichtungen, die nicht immer nach dem Gesichtspunkt leichter Zugänglichkeit ausgelegt werden können, störend in Erscheinung tritt.Quick release device for flange connections with a horseshoe-shaped Bracket and a clamping screw The invention is based on a quick release device for flange connections which have one behind one of the two flanges to be connected laterally sliding, approximately horseshoe-shaped bracket, the legs of about in their middle each carry a hook-like approach that overlaps the flanges and in its crossbar a by means of a clamping screw on the back of one flange is arranged pressable movable abutment. The pressing force is at this Device generated either by means of a screw or by means of an eccentric, its operation is a twist grip with a large lever arm or a special key required to generate the necessary torque. A lot of space is needed in order to be able to use this known device, which is particularly important for quickly built Test facilities that are not always accessible from the point of view of easy accessibility can be interpreted, occurs in a disruptive manner.

Vorliegende Erfindung stellt eine Spannvorrichtung für Flansche zur Verfügung, welche als Schnellverbindung auch für Versuchseinrichtungen geeignet ist. Zu diesem Zweck ist die eingangs definierte Spannvorrichtung erfindungsgemäß dadurch gekennzeichnet, daß die Spannschraube etwa parallel zur Symmetrieachse des Bügels verläuft und zur Kraftübertragung von der Spannschraube auf das bewegliche Widerlager ein an dem Bügel drehbar gelagerter Winkelhebel vorgesehen ist.The present invention provides a clamping device for flanges Available, which as a quick connection is also suitable for test facilities is. For this purpose, the clamping device defined at the outset is according to the invention characterized in that the clamping screw is approximately parallel to the axis of symmetry of the The bracket runs and for power transmission from the clamping screw to the movable one Abutment an angle lever rotatably mounted on the bracket is provided.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und nachfolgend näher erläutert: In den beiden Figuren bedeuten 1 und 2 die beiden zu verbindenden Flansche einer Rohrverbindung, 3 bedeutet einen hinter den Flanschen aufschiebbaren hufeisenförmigen Bügel, dessen Schenkel 4 und 5 je einen die beiden Flansche übergreifenden hakenförmigen Ansatz 6 tragen. Auf dem Quersteg des Bügels ist ein auf die Rückseite des Flansches 1 anpreßbares Widerlager 7, das an einem Winkelhebel 12 ausgebildet ist, um die Achse 8 beweglich angeordnet. Zur Übertragung der Anpreßkraft auf das bewegliche Widerlager ist eine Spannschraube 9 vorgesehen, die in einer Gewindebohrung des Gehäuses 10 der Spannvorrichtung geführt ist und durch einen Drehgriff 11 betätigt werden kann.An embodiment of the invention is shown in the drawing and explained in more detail below: In the two figures, 1 and 2 mean the two Flanges of a pipe connection to be connected, 3 means one behind the flanges Slidable horseshoe-shaped bracket, the legs 4 and 5 of which are each one of the two Flanges cross hook-shaped approach 6 wear. On the crosspiece of the bracket is a pressable on the back of the flange 1 abutment 7, which is on a Angle lever 12 is designed to be movable about axis 8. To transfer the contact pressure on the movable abutment, a clamping screw 9 is provided, which is guided in a threaded hole in the housing 10 of the clamping device and can be operated by a rotary handle 11.

Die erfindungsgemäße Spannvorrichtung besitzt wesentliche praktische Vorteile gegenüber den bisher bekanntgewordenen Schnellverbindungen für Flansche. Als besondere Vorteile sind hervorzuheben: a) Der Winkelhebel gestattet, die Triebschraube - anders als bei der bekannten Konstruktion - in größerem Abstand von der Achse der Flanschverbindung anzuordnen und gibt damit die Möglichkeit, an Stelle eines kleinen normalen Schraubenkopfes einen Drehgriff zu verwenden, der ohne Spezialschlüssel oder Schraubenzieher leicht zu bedienen ist; b) die Kombination einer Schraube als krafterzeugendem Element und eines Winkelhebels als kraftübertragendem Element ermöglicht es, eine Flanschschnellverbindung zu schaffen, die auch bei kompliziertem Aufbau einer Apparatur an jeder Stelle derselben leicht anzubringen ist, kleine Ausmaße besitzt und deren Bedienung keinen großen Bewegungsraum erfordert.The clamping device according to the invention has essential practical Advantages over the previously known quick connections for flanges. The following are to be emphasized as special advantages: a) The angle lever allows the drive screw - unlike the known construction - at a greater distance from the axis to arrange the flange connection and thus gives the option of replacing a small normal screw head to use a twist grip without a special key or screwdriver is easy to use; b) the combination of a screw as allows force-generating element and an angle lever as a force-transmitting element it is to create a flange quick connection, even with a complicated structure an apparatus can easily be attached at any point of the same, small dimensions and whose operation does not require a large amount of movement.
