Description

Die Erfindung betrifft eine Transportvorrichtung in einem Rohr, insbesondere einem Torpedorohr, vorzugsweise bei einem Unterseeboot, die Be- und Entladevorgänge durch das Rohr ermöglicht und zur Abgabe von Minen oder Containern geeignet ist.The invention relates to a transport device in a tube, in particular a torpedo tube, preferably in a submarine, which enables loading and unloading operations through the tube and is suitable for dispensing mines or containers.

Aus DE-B-1 506 360 ist eine Vorrichtung bekannt, bei der gleitbare Schlitten von Kolben-Zylinder-Aggregaten angetrieben werden und eine zusätzliche Beschleunigung beim Abschießen von Überwasser-Torpedos durch Seilzüge, die in Form eines umgekehrt arbeitenden Flaschenzuges ausgebildet sind, erreicht wird. Die als Schleuder ausgebildeten Seilzüge sind so angeordnet, daß der Schlitten etwa den vierfachen Kolbenweg der in den Zylindern bewegten Kolben zurücklegt. Diese bekannte Einrichtung dient jedoch nur dem Abschuß von Überwasser-Torpedos und ist nicht für Ladevorgänge oder für die Anwendung in Unterseebooten geeignet.From DE-B-1 506 360 a device is known in which slidable carriages are driven by piston-cylinder units and an additional acceleration is achieved when firing over-water torpedoes by means of cables which are designed in the form of an inverted pulley system . The cables, which are designed as slingshots, are arranged in such a way that the slide covers approximately four times the piston travel of the pistons moving in the cylinders. However, this known device is only used to launch surface torpedoes and is not suitable for loading operations or for use in submarines.

In US-A-4 640 182 ist eine Vorrichtung für ein Schnellfeuergeschütz zum Ansetzen von Granaten beschrieben. Diese Transportvorrichtung ist im Zentrum eines drehbaren Magazins angeordnet. Sie besteht aus zwei parallelen Zylindern, in den zwei parallele Kolben, die miteinander verbunden sind, verschoben werden. Mit den Kolben wirken zwei parallele Ketten zusammen, die an einem Punkt an den Zylindern befestigt sind und die einen Mitnehmer in der Weise bewegen, daß er beim Ausschieben der Kolben den doppelten Weg der Kolben zurücklegt und mit der doppelten Geschwindigkeit der Kolben bewegt wird. Der Querschnitt dieser Transportvorrichtung ist etwa gleich den lichten Querschnitt zwischen Führungen für die Granaten, so daß sie in Verbindung mit einem Torpedorohr als ungeeignet erscheint, zumal bei diesem eine Vergrößerung der Geschwindigkeit, z. B. bei Ladevorgängen, aber auch bei der Abgabe von Minen und Containern nicht notwendig ist.US-A-4 640 182 describes a device for a rapid fire gun for grenade launching. This transport device is arranged in the center of a rotatable magazine. It consists of two parallel cylinders in which two parallel pistons, which are connected to each other, are moved. The pistons interact with two parallel chains, which are attached to the cylinders at one point and which move a driver in such a way that when the pistons are pushed out, they travel twice the distance of the pistons and are moved at twice the speed of the pistons. The cross section of this Transport device is approximately equal to the clear cross-section between guides for the grenades, so that it appears to be unsuitable in connection with a torpedo tube, especially since this increases the speed, for. B. for loading operations, but also when dispensing mines and containers is not necessary.

Die Beladung der Unterseeboote mit Torpedos, Minen und Containern erfolgt üblicherweise durch die oberen Torpedorohre, die in einer entsprechend getrimmten Lage des Bootes aus dem Wasser ragen. Dabei werden die Gegenstände auf Führungsbahnen geführt. Um auch ihre Bewegung in axialer Richtung steuern zu können, ist es zweckmäßig, sie durch eine Ladeeinrichtung an ihrem ins Boot weisende Ende zu erfassen und sie in das Rohr zu ziehen, beziehungsweise in umgekehrter Richtung aus dem Boot abzugeben. Die Ladeeinrichtung ist also im wesentlichen über die gesamte Länge des Rohres in diesem zu bewegen. Dabei ist den beengten Raumverhältnissen des als druckfester zylindrischer Körper geformten Rohres, das als Torpedo-Ablaufrohr ausgebildet ist, Rechnung zu tragen.The submarines are usually loaded with torpedoes, mines and containers through the upper torpedo tubes, which protrude from the water in a suitably trimmed position of the boat. The objects are guided on guideways. In order to also be able to control their movement in the axial direction, it is expedient to grasp them by a loading device at their end pointing into the boat and to pull them into the tube, or to discharge them from the boat in the opposite direction. The loading device can therefore be moved essentially over the entire length of the tube. The cramped space of the tube, which is shaped as a pressure-resistant cylindrical body and is designed as a torpedo drain tube, must be taken into account.

US-A-3 807 274 zeigt ein Torpedorohr, bei dem ein Torpedo oder ähnlicher Körper durch einen an einer durch einen Hydraulikmotor bewegten Kette angeordneten Mitnehmer ausgeschoben wird. Der Weg des Mitnehmers erstreckt sich jedoch nicht über die ganze Länge des Rohres. Die Kette läuft nicht innerhalb des kreisförmigen Querschnitts des Rohres, sondern in einer etwa halbkreisförmigen Ausbuchtung, die die Druckfestigkeit des Kreisquerschnitts vermindert oder zusätzliche Maßnahmen zur Erhaltung der Festigkeit erfordert.US-A-3 807 274 shows a torpedo tube in which a torpedo or similar body is pushed out by a driver arranged on a chain moved by a hydraulic motor. However, the path of the driver does not extend over the entire length of the pipe. The chain does not run within the circular cross section of the tube, but in an approximately semicircular bulge, which reduces the compressive strength of the circular cross section or requires additional measures to maintain the strength.

Es ist ferner aus der Firmenschrift "Technical Draft Torpedo Tube Set IK 800" der Krupp Mak Maschinenbau GmbH ein Torpedorohr mit einer Ausschubeinrichtung (die die Grundlage des Oberbegriffs des Anspruchs 1 bildet) bekannt, die einen Aufnahmeschlitten, eine Antriebseinrichtung in Form einer Kolben-Zylinder-Einheit und eine Transportkette umfaßt, mit der ein Hub der Kolben-Zylinder-Einheit eine größere Hubbewegung des Aufnahmeschlittens ergibt. Bei dieser Einrichtung ist der Zylinder der Kolben-Zylinder-Einheit fest im Rohr angeordnet. Die Kolbenstange nimmt einen ersten Schlitten mit, der in besonderen Führungen verschiebbar ist und auf dem der Aufnahmeschlitten mittels der Transportkette bewegt wird. Diese Einrichtung weist neben der Kolben-Zylinder-Einheit im Rohr zwei axial zu verschiebende Schlitten auf und erfordert daher einen größeren Rohrdurchmesser als an sich für die Abgabe der eingebrachten Gegenstände notwendig ist, was zu erhöhtem Platzbedarf und Gewicht des Rohres führt. Der Schrift ist eine weitere Lösung zu entnehmen, bei der eine Gewindespindel einerseits fest gelagert ist und ein Spindelgehäuse axial im Rohr bewegen kann, das selbst in einer Führungsbahn läuft und eine Führung für den Aufnahmeschlitten aufweist. Diese Antriebseinrichtung ermöglicht jedoch nur eine geringe Ausschubgewindigkeit und läßt ein meist unerwünschtes Geräusch erwarten.It is also known from the company specification "Technical Draft Torpedo Tube Set IK 800" from Krupp Mak Maschinenbau GmbH a torpedo tube with an extension device (which forms the basis of the preamble of claim 1), which has a receiving carriage, a drive device in the form of a piston-cylinder -Unit and includes a transport chain with which a stroke of the piston-cylinder unit results in a larger stroke movement of the receiving carriage. In this device, the cylinder of the piston-cylinder unit is fixed in the tube. The piston rod takes along a first carriage, which can be moved in special guides and on which the receiving carriage is moved by means of the transport chain. This device has in addition to the piston-cylinder unit in the tube two axially displaceable slides and therefore requires a larger tube diameter than is necessary for the delivery of the objects brought in, which leads to increased space and weight of the tube. The document shows a further solution in which a threaded spindle is fixedly mounted on the one hand and can move a spindle housing axially in the tube, which itself runs in a guideway and has a guide for the receiving carriage. However, this drive device allows only a low extension speed and a mostly undesirable noise can be expected.

Aufgabe der Erfindung ist es daher, eine in einem Rohr, insbesondere in einem Torpedorohr anbringbare Transporteinrichtung zu schaffen, die einen Hub von nahezu der Länge des Rohres bei einwandfreier Führung der bewegtenTeile bewirkt, die hydraulisch mit ausreichender Gewindigkeit angetrieben werden kann und die eine flache Bauweise aufweist.The object of the invention is therefore to provide a transport device which can be fitted in a tube, in particular in a torpedo tube, which brings about a stroke of almost the length of the tube with perfect guidance of the moving parts, which can be driven hydraulically with sufficient threading and which has a flat design having.

Diese Aufgabe wird gemäß Anspruch 1 durch eine in dem Rohr angeordnete Transportvorrichtung gelöst, die eine Kolben-Zylinder-Einheit und einen Aufnahmeschlitten umfaßt, der über einen Seilzug bei einer Bewegung der Kolben-Zylinder-Einheit in der Weise angetrieben wird, daß eine Hubbewegung der Kolben-Zylinder-Einheit eine etwa doppelte Hubbewegung des Schlittens ergibt. Die Kolbenstange ist der zur Achse des Rohres parallel angeordneten Kolben-Zylinder-Einheit im Rohr nahe dessen innerem Ende fest angeordnet, wobei daß der Zylinder außen profiliert und auf einer Gleitschiene geführt verschiebbar ist, während der Schlitten auf der als Gleitbahn profiliert ausgebildeten, zur Mitte des Rohres weisenden Seite des Zylinders bewegbar ist. Bei fester Kolbenstange ist der Zylinder in axialer Richtung in dem Rohr auf einer Gleitschiene beweglich, und zugleich kann der Schlitten sich in derselben Richtung auf dem Zylinder verschieben. Zwei Umlenkräder des Seilzuges sind auf dem Zylinder angeordnet. Der Schlitten ist an einem Trum des Seilzuges befestigt. Die Enden des Seilzuges werden an Befestigungseinrichtungen gespannt und gehalten, die mit dem Rohr fest verbunden sind. Hierdurch wird erreicht, daß eine Verschiebung des Zylinders zwischen seinen beiden Endstellungen zugleich den Schlitten auf dem Zylinder zwischen den beiden Enden des Zylinders verschiebt.This object is achieved according to claim 1 by a transport device arranged in the tube, which comprises a piston-cylinder unit and a receiving carriage which is driven by a cable when the piston-cylinder unit moves in such a way that a lifting movement of the Piston-cylinder unit results in an approximately double stroke movement of the slide. The piston rod is the piston-cylinder unit arranged parallel to the axis of the tube in the tube near its inner end, whereby the cylinder is profiled on the outside and slidably guided on a slide, while the slide on the profiled as a slideway, to the center of the tube-facing side of the cylinder is movable. When the piston rod is fixed, the cylinder can move axially in the tube on a slide rail, and at the same time the slide can move in the same direction on the cylinder. Two pulley pulleys are located on the cylinder. The sled is attached to a run of the cable. The ends of the cable are tensioned and held on fastening devices that are firmly connected to the tube. This ensures that a displacement of the cylinder between its two end positions simultaneously moves the carriage on the cylinder between the two ends of the cylinder.

Die Kolben-Zylinder-Einheit ist vorzugsweise so ausgebildet, daß im Zylinder je ein Hubraum vor und hinter dem mit der Kolbenstange verbundenen Kolben angeordneten sind. Für die Zu- und Abführung des Druckmediums in die Hubräume ist die Kolbenstange mit Kanälen versehen. Die Bewegungen des Zylinders werden durch den Differenzdruck zwischen den beiden Hubräumen gesteuert.The piston-cylinder unit is preferably designed such that a cylinder is arranged in front of and behind the piston connected to the piston rod in the cylinder. The piston rod is provided with channels for the supply and discharge of the pressure medium into the displacement. The movements of the cylinder are controlled by the differential pressure between the two displacements.

Die Kolbenstange ist einerseits in einem festen Lager und andererseits in dem Kolben gelagert, der sich in dem verschiebbaren Zylinder befindet. Es kann ein weiteres Lager für die Kolbenstange zweckmäßig sein, das auf der Gleitschiene verschiebbar ist und beim Ausschieben des Zylinders über einen Teil des Weges durch einen Schlepprahmen mitgenommen wird und das die Kolbenstange auf etwa halber Länge bei ausgeschobenem Zylinder abstützt.The piston rod is mounted on the one hand in a fixed bearing and on the other hand in the piston which is located in the displaceable cylinder. Another bearing for the piston rod may be expedient, which is displaceable on the slide rail and is carried along part of the way by a drag frame when the cylinder is pushed out and which supports the piston rod over approximately half the length when the cylinder is pushed out.

Weitere Einzelheiten werden anhand des auf dem beigefügten Zeichnungen vereinfacht dargestellten Ausführungsbeispieles beschrieben.Further details will be described with reference to the embodiment shown in simplified form on the accompanying drawings.

Das Torpedorohr 1 ist an seinem inneren Ende 12 durch eine nicht dargestellt Klappe abgeschlossen und erweitert sich zu seinem ebenfalls nicht gezeigten anderen Ende. In dem Rohr 1 werden die Gegenstände durch Führungsbahnen 13 (Fig. 2) zentriert und geführt.The torpedo tube 1 is closed at its inner end 12 by a flap (not shown) and widens to its other end, also not shown. The objects are centered and guided in the tube 1 by guideways 13 (FIG. 2).

In dem Rohr ist eine Kolbenstange 21 in einem Lager 22 nahe dem inneren Ende 12 gelagert und durch eine Verschraubung 39 festgehalten (Fig. 1). Die Kolbenstange 21 ist im wesentlichen hohl. In ihren Innenraum ist ein Rohr 23 eingesetzt. Das Lager 22 weist für ein hydraulisches Druckmedium Zuleitungen 24, 25 auf, von denen eine in das Innere des Rohres 23, das einen Kanal 26 bildet, und die andere in den Zwischenraum zwischen dem Rohr und dem inneren Umfang der Kolbenstange 21, wo ein weiterer ringförmiger Kanal 27 gebildet wird, führt. Am Ende der Kolbenstange 21 befindet sich der Kolben 30. Der Zylinder 31 ist auf dem Kolben 30 verschiebbar. Auf der äußeren Seite des Kolbens befindet sich ein erster Hubraum 28, der nach außen hin durch ein Einsatzteil 36 aus Kunststoff und den Zylinderkopf 32 abgeschlossen wird. In den Hubraum 28 mündet der Kanal 26. Ein weiterer Hubraum 29 befindet sich auf der inneren Seite des Kolbens 30 zwischen dem Zylinder 31 und der Außenfläche der Kolbenstange 21 und wird nach innen hin durch ein mit dem Zylinder 31 verbundenes, auf der Kolbenstange 21 abdichtend gleitendes Teil 38 begrenzt. Der Hubraum 29 ist durch Bohrungen in der Kolbenstange 21 mit dem Kanal 27 verbunden.In the tube, a piston rod 21 is mounted in a bearing 22 near the inner end 12 and held in place by a screw 39 (FIG. 1). The piston rod 21 is essentially hollow. A tube 23 is inserted into its interior. The bearing 22 has supply lines 24, 25 for a hydraulic pressure medium, one of which leads into the interior of the tube 23, which forms a channel 26, and the other into the space between the tube and the inner circumference of the piston rod 21, where another annular channel 27 is formed leads. The piston 30 is located at the end of the piston rod 21. The cylinder 31 is displaceable on the piston 30. On the outer side of the piston there is a first displacement 28, which is closed to the outside by an insert 36 made of plastic and the cylinder head 32. The channel 26 opens into the displacement 28. A further displacement 29 is located on the inner side of the piston 30 between the cylinder 31 and the outer surface of the piston rod 21 and is sealed towards the inside by a seal on the piston rod 21 which is connected to the cylinder 31 sliding part 38 limited. The displacement 29 is connected to the channel 27 by bores in the piston rod 21.

Die Außenflächen des Zylinders 31 sind an den beiden radial zur Rohrmitte liegenden Seiten profiliert und als Führungsflächen nach Art eines Schwalbenschwanzes ausgebildet. Mittels Gleitflächen 33 ist der Zylinder 31 auf einer entsprechend geformten Gleitschiene 35 aus Kunststoff geführt verschiebbar, die an der Innenwand des Rohres 1 verläuft. Die im Rohr 1 radial innere Seite des Zylinders 31 bildet eine Gleitbahn 34, auf der die mit entsprechenden Profilierungen 41 geformte Seite des Schlittens 4 geführt wird und gleiten kann. (Fig. 2).The outer surfaces of the cylinder 31 are profiled on the two sides lying radially to the center of the tube and are designed as guide surfaces in the manner of a dovetail. By means of sliding surfaces 33, the cylinder 31 can be moved on a correspondingly shaped sliding rail 35 made of plastic, which runs on the inner wall of the tube 1. The radial in tube 1 inner side of the cylinder 31 forms a slideway 34 on which the side of the slide 4 formed with corresponding profiles 41 is guided and can slide. (Fig. 2).

Der Seilzug 5 läuft von einer Befestigungseinrichtung 55, die seitlich an der Gleitschiene 35 angebracht sein kann, über eine Umlenkscheibe 53, die mittels einer Halterung 54 ebenfalls an der Gleitschiene 35 angebracht ist, zu einem Umlenkrad 51, das auf dem Zylinderkopf 32 gelagert ist, mit einem ersten Trum weiter parallel zur Achse des Zylinders 31 bis zu einer Befestigung 42, mit der der Schlitten 4 an dem Seilzug festgemacht ist, danach über das Umlenkrad 52 auf dem Gleitteil 38 mit einem entgegengesetzt laufenden Trum zu einer zweiten Umlenkscheibe 53 bis zu einer weiteren Befestigungsvorrichtung 55. Die Umlenkscheiben 53 befinden sich seitlich neben dem Zylinder 31 etwa im Bereich des Kolbens 30. Durch diese Führung des Seilzuges 5 wird erreicht, daß eine Bewegung des Zylinders nach außen (auf der Zeichnung nach rechts) den Schlitten 4 um insgesamt den doppelten Hub des Zylinders nach außen (auf der Zeichnung nach rechts) zieht, wobei der Schlitten 4 von einer Stellung nahe dem Umlenkrad 52 in eine Position an dem Umlenkrad 51 gelangt. Die Längenabmessungen der Vorrichtungsteile sind den notwendigen Hubwegen anzupassen. Der vorgesehene Seilzug 5 führt nicht nur zu einer Vergrößerung des Hubes des Schlittens 4 sondern auch zu einer Beschleunigung seiner Bewegungen.The cable 5 runs from a fastening device 55, which can be attached to the side of the slide rail 35, via a deflection disk 53, which is also attached to the slide rail 35 by means of a holder 54, to a deflection wheel 51, which is mounted on the cylinder head 32, with a first strand parallel to the axis of the cylinder 31 up to a fastening 42 with which the carriage 4 is fastened to the cable, then via the deflection wheel 52 on the sliding part 38 with an oppositely running strand to a second deflection disk 53 up to one further fastening device 55. The deflection disks 53 are located laterally next to the cylinder 31, approximately in the area of the piston 30. This guidance of the cable pull 5 ensures that the cylinder 4 is moved outwards (to the right in the drawing) by a total of 4 double stroke of the cylinder to the outside (to the right in the drawing), the carriage 4 from a position na he the deflection wheel 52 comes into a position on the deflection wheel 51. The length dimensions of the device parts must be adapted to the necessary stroke paths. The cable 5 provided not only increases the stroke of the carriage 4 but also accelerates its movements.

Der Schlepprahmen des Lagers 37 und konstruktive Einzelheiten wie Dichtungsringe und Abstützungen des Rohres 23 in der Kolbenstange 21 sind zur Vereinfachung der nur schematischen Zeichnungen nicht dargestellt. Es ist ferner der auf dem Schlitten 4 anzubringende Ladebock mit der Aufnahmeeinrichtung für die Gegenstände nicht gezeigt.The drag frame of the bearing 37 and structural details such as sealing rings and supports of the tube 23 in the piston rod 21 are not shown to simplify the only schematic drawings. Furthermore, the loading frame to be attached to the carriage 4 with the receiving device for the objects is not shown.

Die vorgesehene Ausbildung der Kolben-Zylinder-Einheit mit einem verschiebbaren Zylinder bei feststehendem Kolben und fester Kolbenstange ermöglicht nicht nur eine einwandfreie Lagerung des ausschiebbaren Teiles dieser Einheit, sondern vereinfacht den gesamten Aufbau der Transportvorrichtung durch die Schaffung einer gleitenden Führung für den Schlitten direkt auf dem bewegten Zylinder, wodurch auch eine sehr flache Bauweise der Transportvorrichtung erreicht wird, mittels der der Schlitten über fast die gesamte Lange des Rohres bewegbar ist.The proposed design of the piston-cylinder unit with a displaceable cylinder with a fixed piston and a fixed piston rod not only enables the slide-out part of this unit to be stored correctly, but also simplifies the entire structure of the transport device by creating a sliding guide for the slide directly on the moved cylinder, whereby a very flat design of the transport device is achieved, by means of which the carriage can be moved over almost the entire length of the tube.
