Description

Im Bergbau sind zur Luftführung für die eingesetzten Maschinen und zur Sonderbewetterung erhebliche Mengen an Rohrleitungen zu verlegen. Die Druckluft für die Maschinen wird von Tage in die Grube geleitet. Zum Zwecke der -Sonderbewetterung werden Luttenventilatoren in der Grube verwendet. Diese drücken oder saugen die Luft (Wetter) durch sog. Wetterlutten; das sind leicht gehaltene, dünnwandige Rohre, zu dem zur Sonderbewetterung vorgesehenen Ort.In mining, the machines and Laying considerable amounts of pipelines for special ventilation. The compressed air for the machines, days are passed into the pit. For the purpose of special ventilation duct fans are used in the pit. These press or suck the Air (weather) through so-called weather flutes; these are light-weight, thin-walled tubes, to the place intended for special ventilation.

Die Wetterlutten sind bekannt als Einstecklutten, wobei die Luttenenden lose ineinander gesteckt werden. Bei einer anderen Ausführung werden die Luttenenden mit aufgeschweißten Bunden mit quadratischem Querschnitt versehen. Durch lose Flansehe, die sich vor die Bunde legen, werden die Luttenenden mittels Schrauben miteinander verbunden. Die zuerst genannten Luttenverbindungen haben den Nachteil, daß sie sehr undicht sind. Bei der zweiten Ausführung ist die Abdichtung an der Verbindungsstelle durch das Aufeinanderdrücken der Stirnflächen gut. Beide Ausführungen haben jedoch den Nachteil, daß sie starr sind und nur gerade verlegt werden können.The weather ducts are known as plug-in ducts, with the duct ends loosely inserted into each other. In another design, the duct ends provided with welded-on collars with a square cross-section. Through loose flanges, that lie in front of the bundles, the ends of the ducts are connected to one another by means of screws tied together. The first-mentioned pipe connections have the disadvantage that they are very are leaking. In the second version, the seal is at the connection point by pressing the end faces together well. However, both versions have the disadvantage that they are rigid and can only be laid straight.

Die Rohrleitungen für die Druckluft der Maschinen werden durch Flansche oder Kugelkupplungen miteinander verbunden. Bei der Flanschverbindung ist eine Verlegung in Kurven nicht möglich. Ein Nachgeben der Verbindung bei auftretendem Druck ist ebenfalls ausgeschlossen. Besser ist die Verbindung mittels Kugelkupplungen; ihre Herstellung ist jedoch sehr teuer.The pipes for the compressed air of the machines are through flanges or ball couplings connected to one another. The flange connection involves laying not possible in curves. There is a yielding of the connection when pressure is applied also excluded. The connection by means of ball couplings is better; their However, it is very expensive to manufacture.

Die Nachteile der Rohr- und Luttenverbindungen sollen durch die Ausführung der vorliegenden Erfindung behoben werden. Erfindungsgemäß werden überan den;Rohrenden vorgesehene Verstärkungsringo zweier zusammenstoßender Röhre Dichtungsringe gelegt, über die eine Bandschelle gezogen wird. Die Bandschelle verbindet die Rohrenden und dichtet sie zugleich ab. Ein weiterer Vorteil dieser Rohrverbindungen ist der, daß die Rohre ohne besondere Zwischenstücke nach jeder Richtung winklig, also auch in Kurven verlegt werden können. Bei auftretendem Druck gibt die Verbindung nach, ohne daß deren Dichtigkeit und Verbindung darunter leidet. Die Herstellung dieser Rohrverbindung ist ferner einfach und billig. In Abb. i der Zeichnung ist die Rohrverbindung dargestellt. Abb.2 zeigt eine Seitenansicht dazu. In Abb. 3 ist ein Schnitt durch gerade und winklig verlegte Rohre dargestellt.The disadvantages of the pipe and duct connections are intended to be due to the execution of the present invention. According to the invention over the; pipe ends provided reinforcement ringo of two tube sealing rings that meet, over which a band clamp is pulled. The band clamp connects the pipe ends and seals it at the same time. Another advantage of these pipe connections is that that the tubes are angled in every direction without any special spacers, so too can be laid in curves. When pressure occurs, the connection gives way, without their tightness and connection suffering. The making of this Pipe connection is also simple and cheap. In Fig. I of the drawing is the pipe connection shown. Fig.2 shows a side view of this. In Fig. 3 is a section through Straight and angled pipes are shown.

Die -Rehre a werden an ihren Enden mit aufgeschweißten. Verstärkungsringen b aus rundem oder anderem Profil versehen. Über diese wird der Dichtungsring c gelegt, welcher erheblich breiter ist als die yerstärkungsringe b zweier zusammenstoßender Rohrenden.The -Rehre a are welded on at their ends. Reinforcement rings b made of a round or other profile. The sealing ring c is placed over this, which is considerably wider than the reinforcement rings b of two colliding ones Pipe ends.

Durch das dem Dichtungsring c angepaßte Schellenband d wird der Dichtungsring c mittels einer oder mehrerer Sehrauben e gegen die Verstärkungsringe b gedrückt, wodurch eine gleichzeitige Verbindung und Abdichtung der Rohrenden erfolgt. ' Das Schellenband d ist am Umfang mit mehreren Klammern f versehen. Diese verhüten, daß die Rohre über einen bestimmten Winkel hinaus abgelenkt werden. An einem Ende des Schellenbandes d ist ein dünnes Stahlblech g befestigt, welches sich lose in das gegenüberliegende Schellenbandende legt. Es gewährleistet, daß der Dichtungsring c sich auch in dem sich' an den Schellenbandenden bildenden Spalt gut gegen den Verstärkungsring b legt.By means of the clamp band d adapted to the sealing ring c, the sealing ring becomes c pressed against the reinforcement rings b by means of one or more visual screws e, whereby a simultaneous connection and sealing of the pipe ends takes place. ' That Clamp band d is provided with several brackets f on the circumference. These prevent that the pipes are deflected beyond a certain angle. At one end of the The clamp band d is attached to a thin sheet of steel g, which loosely fits into the opposite end of the clamp band. It ensures that the sealing ring c also in the gap that forms at the clamp strap ends well against the Reinforcement ring b lays.
