Description
Durch das Patent 962:246 ist eine Verbolzung für den stählernen Grubenausbau geschützt., bei der die Bolzen mit drehbaren Haken oder Fallen in an den Ausbaurahmen angeordneten Bolzenhalterungen im Eingriff stehen bzw. mit dies-en Halterungen zur Befestigung an den Ausbaurahmen in Eingriff gebracht werden können. Um eine Sicherung der Bolzen gegen Herausfallen ti gen, beispielsweise während des aus den Halterung Schie&ns zu verhindern, sollen- nach der Hauptpatentanmeldüng die Haken mit verformbaren Nasen versehen sein.The patent 962: 246 provides a bolting for the steel pit lining protected., in which the bolts with rotatable hooks or latches in on the extension frame arranged bolt holders are in engagement or with these holders for Attachment can be brought into engagement with the expansion frame. To a backup the bolt to prevent it from falling out, for example while it is out of the bracket To prevent it from happening, according to the main patent application, the hooks with it deformable lugs.
Die Erfindung betrifft eine Weiterbildung und besonders bevorzugte Ausführungsform des Vorschlages nach der Hauptpatentanmeldung und besteht im wesentlichen darin, daß auf den Bolzen bewegliche Sicherungen angeordnet sind, welche ein Ausschwenken der Haken in der Eingriffsstellung verhindern. Mit besonderem Vorteil können die Sicherungen als auf den Bolzen verschiebbare Schnallen ausgebildet sein, welche in Eingriffstellung über die Haken oder Fallen geschoben werden können. Die Schnallen sind hierbei zweckmäßig nach unten offen ausgebildet, um auch die Bolzenlagerung überfahren zu können.The invention relates to a further development and particularly preferred Embodiment of the proposal according to the main patent application and consists essentially in that movable fuses are arranged on the bolt, which pivoting prevent the hook in the engaged position. The Fuses be designed as slidable buckles on the bolt, which can be pushed into engagement position over the hooks or traps. The buckles are expediently designed to be open at the bottom to also accommodate the bolt mounting to be able to run over.
Weitere vorteilhafte Einzelheiten der Erfindung sind aus der Zeichnung ersichtlich, in welcher die Erfindung beispielsweise veranschaulicht ist. Es zeigt Fig. i eine Verbolzung nach der Erfindung in Seitenansicht, Fig. 2 einen Schnitt gemäß der LinieIl-II der Fig. i in vergrößertem Maßstab. und Fig. 3 eine Verbolzung in Draufsicht.Further advantageous details of the invention can be seen from the drawing, in which the invention is illustrated by way of example. It shows Fig. I a bolting according to the invention in side view, Fig. 2 shows a section according to the LinieIl-II of FIG. I in an enlarged scale. and FIG. 3 shows a bolting in plan view.
In dem dargestellten Ausführungsbeispiel sind mit i die Bolzen bezeichnet, an deren Enden mittels Stiften 2 Haken oder Fallen 3 nach dem Vorschlag der Hauptpatentanmeldung schwenkbar angeordnet sind. In der gezeichneten Riegelstellung sind die Haken 3 mit Bolzenhalterungen 4 als Widerlager t' im Eingriff, welche an den Ausbauprofilen 6 und 7 beispielsweise auf,demWegederBolzenschweißung befestigt sind. In der Eingriffstellung durchdringen dabei die Haken3 Ausschnitte5 an den Enden der Bolzen x. Gemäß der Erfindung sind auf den Bolzen i schnallenförtnige Sicherungen 8 verschiebbar angeordnet, welche in der gezeichneten Eingriffstellung über die Haken3 derart hinweggeschoben sind"daß sie ein unggewolltes Ausschwenken der Haken verhindern. Wie insbesondere aus Fig.:2 ersichtlich, sinddie Schnallen8 unten offen ausgebildet, so daß sie chie durch die StiftC2 gebildeten Schwenklager der Haken 3 ohne weiteres überfahren können.In the illustrated embodiment, the pins are designated by i, at the ends of which hooks or latches 3 are pivotably arranged according to the proposal of the main patent application by means of pins 2. In the locking position shown, the hooks 3 are in engagement with bolt holders 4 as abutments t ', which are fastened to the support profiles 6 and 7, for example on the way of the bolt welding. In the engaged position, the hooks3 penetrate cutouts5 at the ends of the bolts x. According to the invention, buckle-like securing devices 8 are slidably arranged on the bolts i, which in the drawn engagement position are pushed over the hooks 3 in such a way that they prevent the hooks from swiveling out unintentionally. As can be seen in particular from FIG. so that they can easily pass over the swivel bearings of the hooks 3 formed by the pin C2.
In dieser und, ähnlicher Weise kann durch die Erfindung eine einfaehe und, sehr wirksame Sicherung der Verbolzung nach der Hauptpatentanmeldung erreicht werden.In this and similar manner, the invention can make a simple and, very effective securing of the bolting achieved after the main patent application will.
