Description
Ein- und Ausziehvorrichtung für Rohrverbindungen Zum Zusammenfahnen von Rohrverbindunge@n mit Rollgummidichtungen wird ein bestimmter Kraftaufwand benötigt. Bei kleinen lichten Weiten der Muffenrohre genügt hierzu die menschliche Arbeitskraft; bei größeren lichten Weiten sind infolge des größeren Gewichtes der Rohre und des größeren Rollwiderstandes der Rundgummidichtung besondere Vorrichtungen notwendig, um die Rohrverbindung zusammenzufahren. Bisher wurde im Graben mit einem Querholz ein_ fViderlager geschaffen und das letztere Muffenrohr mittels einer Winde so weit gedrückt, bis die Muffenverbindung geschlossen war, oder man zog mit Seilen, die um das Rohr geschlungen waren, die Rohrverbindung zusammen. Die erste Einrichtung läßt sich nur, bei günstigen Grabenverhältnissen und festem Boden veniirklichen. Die zweite Arbeitsweise ist bei tiefen oder ausgeschalten Rohrgräben nicht möglich, da der Schrägzug zu stark ist oder die Ausschalungen im Wege sind. Weiter war schon vorgesehen, um Muffe und Rohrende Rohrschellen zu legen t id diese Rohrschellen mit Schraubenspindeln zusammenzufahren, um die Muffenverbindung zu schließen. Auch dies erwies sich als sehr umständlich, so daß es nur in Notfällen angewandt wurde. Endlich hat man die Rohre bereits dadurch zusammengezogen, daß man zwischen eine das Ende des bereits gelegten Rohres umfassende Zange mit Scharnier und einen am Ende des einzuziehenden Rohres festgehaltenen Haken eine Kette einhängte, die durch einen an dem Haken angebrachten doppelarmigen Hebel angezogenwerden konnte. Der für einen Hub des Hebels erzielte Weg des einzuziehenden Rohres war nur gering und wurde durch die Federung der Zange und die Nachgiebigkeit der Kettenglieder noch weiter ungünstig beeinflußt, so daß das Arbeiten mit dieser einseitig - angebrachten behelfsmäßigen Vorrichtung umständlich und unbefriedigend war.Pulling in and pulling out device for pipe connections To pull together pipe connections with rubber seals, a certain amount of force is required. In the case of small clear widths of the socket pipes, human labor is sufficient for this; In the case of larger clearances, special devices are necessary in order to close the pipe connection due to the greater weight of the pipes and the greater rolling resistance of the round rubber seal. Up to now, an abutment was created in the trench with a cross piece of wood and the latter socket pipe was pressed by means of a winch until the socket connection was closed, or the pipe connection was pulled together with ropes that were looped around the pipe. The first device can only be, veniirklichen under favorable conditions grave and solid ground. The second method of working is not possible with deep or closed pipe trenches because the diagonal pull is too strong or the formwork is in the way. It was also planned to place pipe clamps on the socket and pipe end to move these pipe clamps together with screw spindles in order to close the socket connection. This also turned out to be very cumbersome, so that it was only used in emergencies. The pipes have finally been drawn together by hanging a chain between a pair of hinged pliers encircling the end of the pipe that has already been laid and a hook held at the end of the pipe to be drawn in, which chain could be tightened by a double-armed lever attached to the hook. The path of the pipe to be drawn in for one stroke of the lever was only slight and was further adversely affected by the springiness of the pliers and the flexibility of the chain links, so that working with this one-sided makeshift device was cumbersome and unsatisfactory.
Die vorliegende Erfindung vermeidet .die ofenerwähnten Nachteile und macht das Zusammenfahren der Rohrverbindungen vollkommen unabhängig von den örtlichen Verhältnissen. je eine z. B. zweiteilige Rohrschelle i und a wird um die Muffe bzw. das Einsteckende gelegt und in geeigneter Weise auf dem Rohr lösbar befestigt. An diesen Schellen befinden sich auf beiden Seiten der Rohre Ösen 3 und 4., die entweder an den Schellen fest angebracht sind oder mit ihnen verbunden «erden, beispielsweise in der gezeichneten Art. An der Öse 3 greift über ein Zwischenstück 5 ein geschlitzter Hebel 6 an, der in einem gewissen Abstand von dem unteren Drehpunkt einen Zapfen 7 aufweist. An der ös:e .l greift eine Zahnstange 8 an, die eine Anzahl von Rasten 9 besitzt. Die Zahnstange 8 wird in dem Schlitz des Hebels 6 geführt, und die entsprechende Raste greift in den Zapfen 7 ein, wie in der Abbildung dargestellt. Das Zusammenfahren geschieht nun folgendermaßen: -Beide Hebel werden nach links bewegt, bis die Bewegungsmöglichkeit gesperrt ist. Dann wird zunächst auf der ,einen Seite mit dem Hebel in eine der zurückliegenden Rasten zurückgegriffen, während die andere Seite festgeh-alten wird, damit die vom Gummi ausgeübte Kraft die Rohrverbindung nicht mehr aus:einanderdrücken kann. Dieser Vorgang wird anschließend auch auf der anderen Seite ausgeführt, worauf dann wieder beide Hebel nach links bewegt werden und die Muffenverhindung vollkommen eingefahren wird.The present invention avoids. The disadvantages mentioned and makes the joining of the pipe connections completely independent of the local ones Circumstances. one z. B. two-part pipe clamp i and a is around the socket or placed the male end and releasably fastened in a suitable manner on the pipe. At these clamps are located on both sides of the tubes eyelets 3 and 4., which are either are firmly attached to the clamps or connected to them «earthed, for example in the drawn art. At the eyelet 3 engages via an intermediate piece 5 a slotted Lever 6, which has a pin at a certain distance from the lower pivot point 7 has. At the ös: e .l engages a rack 8, which has a number of notches 9 owns. The rack 8 is guided in the slot of the lever 6, and the corresponding The catch engages in the pin 7, as shown in the figure. The move together now happens as follows: -Both levers are moved to the left until the movement is possible Is blocked. Then first on one side with the lever in one of the the rest of the notches, while the other side is held fast, so that the force exerted by the rubber no longer pushes the pipe connection apart can. This process is then also carried out on the other side, whereupon then both levers are moved to the left again and the socket connection is complete is retracted.
Der Hebel 6 kann auch direkt an der Öse 3 ohne das Zwischenstück 5 befestigt werden, jedoch hat die Lösung mit dem Zwischenstück den Vorteil, daß die Seitenbeweglichkeit des Hebels größer wird, wodurch hin, Klemmen der Zahnstangen in dem Schlitz vermieden wird. Die Vorrichtung weist außerdem noch einen grundsätzlichen Vorteil auf, dadurch, daß die Mufbenrohrverbindung ohne weiteres wieder - auseinandergefahren werden kann, wenn sich beim Zusammenfahren irgendeine Unstiminigkeit herausgestellt hat. Dazu ist es nur notwendig, die Zahnstange 8 so umzukehren. daß die Rasteng in der umgekehrten Richtung liegen. Der Ausziehvorgang erfolgt genau auf dieselbe Art und Weise wie beim Einziehen, nur daß der Hebel in der umgekehrten Richtung bewegt wird. Bei den früheren Verfahren machte das ,#,ustinanderziehen von Rollgummidichtungen teilweise erhebliche Schwierigkeiten, da es leicht vorkommen konnte, daß nicht die gewünschte 1@Iufte, sondern irgendeine andere Muffe des Rohrstranges infolge ihres geringeren Widerstandes aus:einandergezogenwurde.The lever 6 can also be attached directly to the eyelet 3 without the intermediate piece 5 be attached, but the solution with the intermediate piece has the advantage that the Lateral mobility of the lever becomes greater, thereby jamming the racks in the slot is avoided. The device also has a basic one Advantage, in that the socket pipe connection easily again - moved apart if any indifference is found when pulling together Has. For this it is only necessary to reverse the rack 8 in this way. that the Rasteng lie in the opposite direction. The pulling process takes place exactly on the same The same way as for retraction, except that the lever works in the opposite direction is moved. In the earlier methods, this was done by pulling rubber seals together sometimes considerable difficulties, since it could easily happen that the desired 1 @ Iufte, but any other socket of the pipe string as a result of it less resistance: was pulled apart.
