Abstract

Ventilation ducting accumulator (3) for use in mine road heading operations uses an inflatable sleeve (4) as brake in the paying out of the ducting stored in the accumulator. Preferably this braking sleeve should be held in two half shell bearings, with air supply adjusted by means of a reduction valve fitted for the purpose. The arrangement ensures that the ducting (5) is held in constant tension throughout the paying out and installation sequences during advance of the roadhead where the ducting is to form the ventilation route.

Description

Beschreibung und Erläuterung zur Patent- und Hilfs-Gebrauchsmusteranmeldung. "Luttenspeicher mit pneumatiseher Spannvorrichtung, vorzugsweise für den untertätigen Berg- und Tunnelbau." Im Bergbau und im Tunnelbau werden im umfangreichen Maße zur Aufführung von Strecken Teil- und Volischnittinaschinen eingesetzt.Description and explanation of the patent and auxiliary utility model application. "Duct storage with pneumatic clamping device, preferably for the under-working Mining and tunneling. "In mining and tunneling, Execution of stretch dividing and full cutting machines used.

Die Blasluttentour wird mitgeführt und auf sogenannten Luttenspeichern mit ca. 20 m Länge gespeichert und sukzessiv mit der Ausfahrung der Strecke durch die Tunnel-Auffahrungs-Maschine oder 5 treckenauffahrungs -Maschine vorgezogen.The Blasluttentour is carried along and stored in so-called Luttenspeicher with a length of approx. 20 m and successively with the driving through of the route The tunnel excavation machine or 5 track excavation machine is preferred.

Um die Lutten auf dem Speicherstück gespannt zu halten, gibt es viele Möglichkeiten der mechanischen Spannung. Jedoch ist die Abbremsung über mechanische Hilfsmittel bisher nur unzureichend gewährleistet worden.There are many to keep the ducts taut on the memory piece Mechanical tension possibilities. However, the braking is mechanical Aids have so far only been insufficiently guaranteed.

Um in einfachster Weise eine immer gleichbleibende Vorspannung zu erzielen, wird erfindungsgemäß vorgeschlagen, die Vorspannung durch einen aufblasbaren, schlauchförmigen Körper zu erzeugen.In order to achieve a constant preload in the simplest possible way achieve, is proposed according to the invention, the bias by an inflatable, to produce tubular body.

In der beilieqenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: mit 1: das perforierte Endstück des Luttenspeichers, mit 2: die Stellklappen, mit 3: der Rohrrahmen zur Speicherung der Faltlutten, mit 4: der aufblähbare rohrförmige Körper, der vorzugsweise in einer Halbschale liegt und über ein Druckminderventil gespreizt und gebläht wird, mit 5: die aufges'peicherte Lutte, die durch den Bremssehlaueh(4) gehalten wird.The embodiment according to the invention is shown in the accompanying drawing shown: with 1: the perforated end piece of the duct storage, with 2: the control flaps, with 3: the tubular frame for storing the folded tubes, with 4: the inflatable tubular Body, which is preferably in a half-shell and over a pressure reducing valve spread and is inflated, with 5: the stored air, which is released by the brake lever (4) is held.

Selbsverständlich ist die Erfindung, nicht auf die vorstehende im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Luttenspeicher für die Bewetterung von Tunnel-oder Bergbau-Strecken so auszubilden, daß die sich abziehende Falt-Lutte durch aufblähbare schlauchförmige Rörper abgebremst wird.It goes without saying that the invention is not limited to the above im individual forms of training shown and described are limited, but rather numerous changes are possible without, however, deviating from the basic idea, to design a Luttenspeicher for the ventilation of tunnel or mining routes in such a way, that the peeling-off folded duct is slowed down by inflatable tubular bodies will.
