Description

Behälter zur Errichtung transportfähiger Gesteinsstaubsperren Eine in der englischen Patentschrift 15 925 von igio erwähnte Gesteinsstaubsperrenart besteht aus geschlossenen Staubpaketen; von denen jedes an einer Kette befestigt, vom Explosionsstoß von seiner Unterlage geschleudert wird und sich durch Ruck, verursacht von der den Fall des Pakets hemmenden Kette, öffnen soll.Container for the erection of transportable rock dust barriers A type of rock dust barrier mentioned by igio in the English patent specification 15 925 consists of closed dust packages; each of which is attached to a chain, is thrown from its base by the explosion and is supposed to open when jerked by the chain preventing the package from falling.

Beim Gegenstand der Erfindung tritt durch die untere beschriebene Aufreißvorrichtung in Verbindung mit den Spannmitteln schon beim ersten der Explosionsflamme vorauseilenden Luftstoß die Wirkung sofort ein.In the subject matter of the invention occurs through the lower described Tear-open device in connection with the clamping devices already at the first of the explosion flame advance air blast takes effect immediately.

Die Neuerung besteht aus beutelartigen Gesteinsstaubbehältern, wie sie in Abb. i, 2 und 3 in Vorder-, Seiten- und Bodenansicht gezeichnet sind, die mit Hilfe einer Aufhängeeinrichtung c unter der Firste aufgehängt werden und -in dessen unteren Teil der Hülle an beiden gegenüberliegenden Seiten Aufreißbahnen gelegt sind, die sich je in der Angriffsstelle a vereinigen. Zwischen diesen einerseits und dem Streckenausbau andererseits werden Spannmittel befestigt, die den Behälter normal in Ruhelage halten. Erfolgt eine vom Explosionsstoß verursachte Pendelbewegung des Behälters, so wird von den Spannmitteln ein Zug an den Aufreißbahnen ausgeübt, wodurch der schraffierte Hüllenteil b aus der Gesamthülle gerissen wird, so daß der Staub austritt.The innovation consists of bag-like rock dust containers, such as they are drawn in Fig. i, 2 and 3 in front, side and bottom views, the can be hung under the roof with the help of a hanging device c and -in the lower part of the envelope on both opposite sides of the tear strips are placed, which each unite in the attack point a. Between these on the one hand and the extension of the track, on the other hand, clamping devices are attached to the container keep normally at rest. There is a pendulum movement caused by the explosion of the container, the tensioning means exert a pull on the tear strips, whereby the hatched shell part b is torn from the overall shell, so that the dust comes out.

In Abb. q. und 5 ist eine vollständige Gesteinsstaubsperre obiger Art im Quer- und Längenschnitt dargestellt.In Fig.q. and 5 is a complete rock dust barrier above Type shown in cross-section and length-section.
