Abstract

The invention relates to a combination of a pusher tug and one or more barge units, whereby each barge unit may comprise one or more barges coupled alongside each other. Between the barge units and/or between the rear-unit and the pusher tug, pivotable pushing connections are installed giving the combination an articulated character. Each of the pivotable pushing connections is only mounted to one of the units or to the pusher tug and is coupled to the opposite unit with usual connections, such as steel wires. The pivotable pushing connections are robust and easy to handle by the normal deck crew. Application of the pivotable and steerable pushing connections increases the safety of pushing traffic on waterways and allows more units per combination.

Description

Die Erfindung bezieht sich auf eine steuerbare Schubvorrichtung für eine Schubkähnekombination, welche Kombination aus einem Schubboot mit mindestens einer Schubkähneeinheit vor dem Schubboot besteht, wobei jede Einheit aus einem, zwei oder mehreren nebeneinander gekuppelten Kähnen bestehen kann, und wobei dass Schubboot versehen ist mit mindestens einer Antriebsvorrichtung, und wobei sich in der Kombination wenigstens eine steuerbare Schubvorrichtung befindet, welche steuerbare Schubvorrichtung einen horizontalen Trägerrahmen umfasst, welcher am Vorsteven befestigt ist, welcher Trägerrahmen einen, um eine vertikale Achse scharnierenden, quer zur Mittellinie der Kombination gelegenen Schubbalken trägt und führt, und wobei zur Steuerung zwischen dem Trägerrahmen und dem Schubbalken beidseitig der Scharnierachse jeweils eine hydraulische Kolbenzylindereinheit oder dgl. verlängerbare und verkürzbare Vorrichtung angeordnet ist.The invention relates to a controllable push device for a push barge combination, which combination consists of a push boat with at least one push barge unit in front of the push boat, wherein each unit can consist of one, two or more coupled barges, and wherein the push boat is provided with at least one Drive device, and wherein in the combination there is at least one controllable pushing device, the controllable pushing device comprises a horizontal support frame which is fastened to the stem, which support frame carries and guides a push bar which is hinged about a vertical axis and is located transversely to the center line of the combination, and wherein for control between the support frame and the push bar on both sides of the hinge axis, a hydraulic piston-cylinder unit or the like.

Das Fahren mit Schubkahnkombinationen auf Flüssen, wie z.B. der Rhein, mit regem Schiffsverkehr und einigen ziemlich scharfen Kurven, fordert nicht nur eine grosse Steuerkunst, sondern wird mitunter beeinflusst durch den übrigen Verkehr auf dem Fahrwasser. Dies hat zufolge, dass die Behörden dieser Wasserwege Grenzen vorgeschrieben haben, nicht nur bezüglich der Breite, doch vor allem in bezug auf die Länge solcher Kombinationen. Am Rhein z.B. sind Kombinationen mit maximal zwei mal zwei Kähnen erlaubt, d.h. eine Einheit von zwei Bord gegen Bord nebeneinander gekuppelten Kähnen, mit anschliessend einer gleichen vorgekuppelten Einheit, wohinter sich in der Mittellinie das Schubboot befindet. An sich könnten die Schubboote, trotz der relativ geringen Wassertiefe, genügend Antriebsleistung liefern um Kombinationen von dreimal zwei Kähnen, d.h. drei Einheiten, oder sogar mehr, zu transportieren. Dabei ist die Manövrierbarkeit einer solchen starren Kombination aber zweifelhaft. In einer solchen Kombination sind alle Kähne untereinander starr miteinander gekuppelt mit Hilfe von Kreuz-, Längs- und Querdrähten. Auch das Schubboot ist starr hinter den Kähnen gekuppelt. Mit Hilfe eines extra Kopfruders ist bei höherer Geschwindigkeit die Steuerbarkeit einigermassen zu verbessern, mit einem Bugpropeller welcher Kräfte nach Steuerbord und Backbord liefern kann, vor allem bei niedriger Geschwindigkeit. Die Erfindung beabsichtigt nun um mit so einfach wie nur möglichen Mitteln einen bedeutend effektiveren Beitrag zu liefern zur Verbesserung der Lenkbarkeit einer solchen Kombination, und zwar derart, dass das Fahren mit längeren Kombinationen von mindestens fünf oder sechs Kähnen in drei Einheiten auch zu den behördlich erlaubten Möglichkeiten gehören kann.Driving with barge combinations on rivers, e.g. the Rhine, with its lively shipping traffic and some rather sharp bends, not only demands great steering skills, but is sometimes influenced by the rest of the traffic on the fairway. As a result, the authorities have imposed limits on these waterways, not only in terms of width, but especially in terms of the length of such combinations. On the Rhine e.g. combinations with a maximum of two times two barges are allowed, i.e. a unit of two barges coupled side by side, followed by the same pre-coupled unit, behind which the pushboat is located in the center line. As such, the push boats, despite the relatively shallow water depth, could provide enough propulsion power to combine three times two barges, i.e. to transport three units, or even more. However, the maneuverability of such a rigid combination is doubtful. In such a combination, all the barges are rigidly coupled to one another with the help of cross, line and cross wires. The push boat is also rigidly coupled behind the barges. With the help of an extra head rudder, the controllability can be improved somewhat at higher speeds, with a bow propeller which can deliver forces to starboard and port, especially at low speed. The invention now intends to make a significantly more effective contribution to improving the maneuverability of such a combination with the simplest possible means, and in such a way that driving with longer combinations of at least five or six boats in three units also allowed the authorities Opportunities may include.

Eine, wie in der Präambel des A1 beschriebene, steuerbare Schubvorrichtung ist bekannt aus der amerikanischen Patentschrift US-A-3 035 537. Mit der in dieser Publikation beschriebenen Vorrichtung wird ein Schubboot starr jedoch beweglich gekuppelt an einem Kahn. Diese Kupplung findet statt mit Scharnierstiften an der Seite des Kahnes, welcher dazu mit geeigneten speziellen Befestigungselementen versehen sein muss. Die beschriebene steuerbare Schubvorrichtung ist gedacht für leichte Anwendungsfälle wie aus der Konstruktion und aus den Beispielen hervorgeht. Anwendung einer derartigen Konstruktion bei Schubkahnkombinationen mit Einheiten von Tausenden von Tonnen im rauhen professionellen Transportwesen auf Flüssen wie dem Rhein, im Transport von z.B. Kohle und Erzen, erscheint ausgeschlossen zu sein. Eines der Probleme dabei ist ohne Zweifel das schwierige Ent- und Ankuppeln von den beschriebenen Schubmitteln an und von den Kähnen, während die Schädigungsanfälligkeit der Befestigungselemente am Hintersteven der Kähne für die beschriebene Anwendung unzulässig ist.A controllable pushing device, as described in the preamble of A1, is known from the US Pat. No. 3,035,537. With the device described in this publication, a pushing boat is coupled rigidly but movably to a barge. This coupling takes place with hinge pins on the side of the barge, which must be provided with suitable special fastening elements. The controllable thrust device described is intended for light applications as can be seen from the construction and from the examples. Application of such a construction in barge combinations with units of thousands of tons in the rough professional transportation on rivers like the Rhine, in the transport of e.g. Coal and ores appear to be excluded. One of the problems is undoubtedly the difficult uncoupling and coupling of the described pushing means to and from the barges, while the susceptibility to damage of the fastening elements on the rear bar of the barges is inadmissible for the application described.

Die Erfindung beabsichtigt nun eine steuerbare Schubvorrichtung zu schaffen welche einfach jedoch besonders robust ist und welche durch das vorhandene Deckpersonal ohne Schwierigkeiten zu handhaben ist bei dem An- und Abkuppeln. Weiterhin beabsichtigt die Erfindung die Anwendungsmöglichkeiten zu vergrössern. Nach der Erfindung wird nun die in der Präambel beschriebene steuerbare Schubvorrichtung dadurch gekennzeichnet, dass bei einer Schubkahnkombination mit mindestens einer weiteren vor der Schubboot-Schubkahnkombination gekuppelten Schubkahneinheit mindestens eine steuerbare Schubvorrichtung zwischen weiter vorne in der Kombination befindlichen Schubkahneinheiten angeordnet ist, und dass sich eine im Wesen gleiche steuerbare Schubvorrichtung zwischen dem Schubboot und der unmittelbar vorgekuppelten Schubkahneinheit befinden kann, dass jede vollständige Schubvorrichtung ausschliesslich an einer der zu kuppelnden Einheiten (Schubboot und/oder Schubkahneinheit) befestigt ist, dass die Schubvorrichtung mit mindestens einem vertikalen Schubknie versehen ist und dass jeweils ein Schubknie als Mittenschubknie in der Mittellinie der Vorrichtung, geeignet zur Kooperation mit der Scharnierachse des Schubbalkens, angeordnet ist, dass die Vorrichtung an der Kuppelseite begrenzt wird durch die im wesentlichen flache Schubfläche des Schubbalkens, und dass für das Kuppeln in der bei starren Kombinationen gebräuchlichen Weise Längs- und Kreuzdrähte oder dgl. zwischen dem Schubbalken und der Einheit verwendet werden. Es spricht für sich, dass in dem Fall wo sich jedoch nur eine in sich starr gekuppelte Schubkahneinheit oder nur ein einziger Schubkahn vor dem Schubboot befindet, im Sinne der Erfindung nur eine steuerbare Schubvorrichtung in der Kombination angeordnet ist. Unter Umständen kann ebenfalls im Sinne der Erfindung die erwünschte Lenkbarkeit auch erreicht werden durch das Anordnen der steuerbaren Schubvorrichtung zwischen ausschliesslich einer oder mehreren Kähneeinheiten, während das Schubboot selbst starr verbunden sein kann. Die amerikanische Patentschrift US-A-3 035 537 zeigt das gebräuchliche, mit Rudern lenkbare Schubboot, jedoch die steuerbare Schubvorrichtung macht es möglich die Ruder entfernbar zu gestalten.The invention now intends to create a controllable pushing device which is simple but particularly robust and which can be handled by the existing deck staff without difficulty when coupling and uncoupling.

Between the push bar and the unit are used. It speaks for itself that, in the case where there is only a rigidly coupled push barge unit or only a single push barge in front of the push boat, only one controllable pushing device is arranged in the combination according to the invention. Under certain circumstances, also within the meaning of the invention, the desired steerability can also be achieved by arranging the controllable pushing device between only one or more barge units, while the pushing boat itself can be rigidly connected. The American patent specification US-A-3 035 537 shows the conventional push boat steerable with oars, but the controllable push device makes it possible to make the rudders removable.

In einigen Fällen wird es vorteilhaft sein wenn der Trägerrahmen parallel zu sich selbst bezüglich seiner Höhenlage verstellbar entlang senkrechter Führungen gestaltet ist welche an den Schubknien befestigt sind. Damit kann ein auftretender Höhenunterschied zwischen vollgeladenen und ungeladenen Kähnen untereinander oder gegenüber dem Schubboot kompensiert werden. Dieser Höhenunterschied kann dabei einige Meter betragen.In some cases it will be advantageous if the support frame is designed to be adjustable parallel to itself with respect to its height along vertical guides which are attached to the push knees. This can compensate for any difference in height between fully loaded and unloaded barges with each other or with respect to the push boat. This difference in height can be a few meters.

Weiterhin beabsichtigt die Erfindung um weitgehend dieselbe Schubvorrichtung anwenden zu können zwischen einerseits einem Schubboot und einem Kahn und anderseits zwischen Kähnen oder Einheiten von Kähnen untereinander. Dazu wird die steuerbare Schubvorrichtung, wenn diese an dem Schubboot befestigt ist, dadurch gekennzeichnet, dass die senkrechten Führungen sich am Schubboot befinden, die eine an einem Steuerbordschubknie und die andere an einem Backbordschubknie und dass sie dafür geeignet sind um horizontale Kräfte wirkend in allen Richtungen aufnehmen zu können.Furthermore, the invention intends to be able to use largely the same pushing device between on the one hand a push boat and a barge and on the other hand between barges or units of barges with one another. For this purpose, the controllable pushing device, when it is attached to the pushing boat, is characterized in that the vertical guides are on the pushing boat, one on a starboard pushing knee and the other on a port pushing knee, and that they are suitable for applying horizontal forces in all directions to be able to record.

Eine Vorzugsausführungsform wird dadurch gekennzeichnet, dass der Schubbalken mit hauptsächlich horizontalen Stützen in Richtung zur Mittellinie des Schubbootes sich abstützt, wo die Stützen befestigt sind an einer senkrechten zylindrischen Säule welche als Scharnierachse ruht in einer senkrechten zylindrischen Rinne als Kontrascharnier, welche Rinne über einen senkrechten mit einem Schegg abwärts verlängerten Mittelschubknie am Vorsteven des Schubbootes befestigt ist, und wobei der Trägerrahmen an der Seite des Schubbalkens die zylindrische Säule in der zylindrischen Rinne drehbar einschliesst.A preferred embodiment is characterized in that the push bar is supported with mainly horizontal supports in the direction of the center line of the push boat, where the supports are attached to a vertical cylindrical column which rests as a hinge axis in a vertical cylindrical channel as a counter hinge, which channel over a vertical with a Schegg downward extended middle thrust knee is attached to the bow of the push boat, and wherein the support frame on the side of the push bar rotatably encloses the cylindrical column in the cylindrical channel.

In korrespondierender Art und Weise wird die Schubvorrichtung, wenn diese an einem oder an zwei nebeneinander gekuppelten Kähnen befestigt ist, in einer Vorzugsausführungsform dadurch gekennzeichnet, dass ein im Wesen horizontaler Vorsetzsteven angeordnet ist, zwischen dem die ganze Schubvorrichtung tragenden Steven und der Schubvorrichtung, welcher Vorsetzsteven die senkrechten Führungen an Steuerbord und an Backbord trägt.In a corresponding manner, the pusher device, if it is attached to one or two coupled barges, is characterized in a preferred embodiment in that an essentially horizontal attachment bar is arranged between the stern carrying the entire pusher device and the pusher device, which attachment pins carries the vertical guides on starboard and port.

Durch die Anwendung eines Vorsetzstevens kann die Schubvorrichtung in demontabler Weise an einem oder mehreren Kähnen befestigt werden und kann dadurch nach Wunsch verwendet oder entfernt werden. So kann z. B. während des Ladens und des Löschens eines Kahnes, die demontable Schubvorrichtung mit dem Vorsetzsteven auf einen anderen Kahn angeordnet werden, welcher für Transport bereit liegt. Nach einer weiteren Ausführungsform wird die Schubvorrichtung dadurch gekennzeichnet, dass der Vorsetzsteven mit zwei um eine vertikale Achse scharnierenden horizontalen Trägern am Deck des Kahnes oder der Einheit befestigt ist, wobei mit einigem Spiel in Öffnungen eingesetzte Hammerkopfbolzen oder dergleichen, eine lösbare Verbindung formen, und dass der Vorsetzsteven abwärts verlängert sein kann und dabei gegen einen breiten Schegg am Steven des Kahnes (der Kähne) sich abstützt.By using an attachment step, the pusher can be removably attached to one or more barges and can be used or removed as desired. So z. B. during the loading and unloading of a barge, the demountable pusher can be arranged with the front bar on another barge which is ready for transport. According to a further embodiment, the pusher device is characterized in that the attachment rod is fastened to the deck of the barge or the unit with two horizontal supports hingeing about a vertical axis, with hammer head bolts or the like inserted into openings, with some play, forming a releasable connection, and that the headstock can be extended downwards and is supported against a broad schegg on the stern of the barge (s).

Da eine derartige Schubvorrichtung und sicherlich jene welche versehen ist mit einem Vorsetzsteven, dazu bestimmt ist um einige schwere Kähne handhaben zu können mit Hilfe von Schubbooten mit installierten Leistungen von tausenden von Kilowatts, sind die Vorrichtungen schwer und kostbar. Insbesondere der Transport, das Anbringen und das Entfernen einer derartigen Vorrichtung bei Kähnen, wird ohne die richtigen Hilfsmittel praktisch unmöglich sein. Nach einer Vorzugsausführungsform der Erfindung sind dazu die Schubvorrichtungen angepasst, damit mit Hilfe des Schubbootes und dessen Schubvorrichtung, die Schubvorrichtung der Kähne in einfacher Weise gehandhabt werden kann. Sie werden nun dadurch gekennzeichnet, dass bei der lösbaren Schubvorrichtung zwischen zwei Kähneeinheiten, der Schubbalken und die Stützen an ihrer Unterseite mit in einer horizontalen Ebene gelegenen Tragflächen und mit einem abwärtsragenden Stift versehen sind, und dass bei der Schubvorrichtung am Schubboot die Oberseite im Wesen flach und horizontal ist und dass in deren Oberseite eine Aufnahmeöffnung angeordnet ist, alles derart, dass das Schubboot mit seiner hebbaren Schubvorrichtung, die Schubvorrichtung zur Anordnung zwischen den Kähnen, kann abheben, transportieren und anbringen, wobei die horizontalen Flächen aufeinander ruhen und der Stift in die Aufnahmeöffnung eingreift.Since such a pushing device, and certainly that which is provided with a push rod, is intended to be able to handle some heavy barges with the help of pushing boats with installed capacities of thousands of kilowatts, the devices are heavy and expensive. In particular, transporting, attaching and removing such a device on barges will be practically impossible without the right tools. According to a preferred embodiment of the invention, the pushing devices are adapted so that the pushing device of the barges can be handled in a simple manner with the help of the pushing boat and its pushing device. They are now characterized in that in the releasable pushing device between two barge units, the push bar and the supports on their underside are provided with wings lying in a horizontal plane and with a downwardly projecting pin, and in the pushing device on the push boat the top is essentially flat and is horizontal and that a receiving opening is arranged in the upper side, all such that the push boat with its liftable push device, the push device for arrangement between the barges, can lift off, transport and attach, the horizontal surfaces resting on one another and the pin in the Engages the receiving opening.

Mit der Schubvorrichtung nach der Erfindung ist es einerseits möglich Schubkähne in einfacher Weise steuerbar zu gestalten für Gebrauch in einer Schubkähnekombination mit dem Lenksystem nach der Erfindung, jedoch anderseits die Kähne auch brauchbar sein zu lassen für klassisch starr gekuppelte Schubkähnekombinationen.With the pushing device according to the invention it is possible on the one hand to make pushbars controllable in a simple manner for use in a pushing bar combination with the steering system according to the invention, but on the other hand to make the barges also usable for classically rigid coupled pushing bar combinations.

Weiterhin sei noch darauf gewiesen, dass die Schubbalken der Schubvorrichtung nach der Erfindung in bekannter Art und Weise mit Hilfe von Längsdrähten und Kreuzdrähten gekuppelt werden mit den Kähnen. Für die Anwendung von der Schubvorrichtung zwischen einem Schubboot und existierenden Kähnen, ist deshalb gar keine Änderung der Kähne notwendig. Nur wenn die Schubvorrichtung nach der Erfindung, versehen von dem Vorsetzsteven, gebraucht wird zwischen Kähnen untereinander, soll der Kahn versehen sein mit Befestigungsmitteln für den genannten Vorsetzsteven. Diese Mittel können jedoch in einfacher Weise im Deck enthalten und derart konzipiert sein, dass sie bei Abwesenheit der Schubvorrichtung nicht störend wirken auf die Kähne in einer bekannten starren Kombination.Furthermore, it should be pointed out that the push bars of the pushing device according to the invention are coupled to the barges in a known manner with the aid of longitudinal wires and cross wires. For the application of the push device between a push boat and existing barges, no change of the barges is therefore necessary. Only if the pusher device according to the invention, provided by the attachment bar, is used between boats among themselves, should the boat be provided with fastening means for the aforementioned attachment bar. However, these means can be contained in the deck in a simple manner and can be designed such that they do not have a disruptive effect on the barges in a known rigid combination in the absence of the pushing device.

Weiterhin kann eine Schubkahnkombination, versehen mit der Steuervorrichtung nach der Erfindung, gegebenenfalls versehen sein mit einem Kopfruder oder einem Bugpropeller.Furthermore, a push barge combination provided with the control device according to the invention can optionally be provided with a rudder or a bow propeller.

Aus der niederländischen Patentanmeldung 7100162 ist eine Lenkvorrichtung bekannt. Nach dieser Publikation (offengelegt am 20. Juli 1971) wird beabsichtigt für das Schieben eines Kahnes einen normalen Schlepper zu verwenden, welcher für diese Gelegenheit als Schubboot verwendet wird. Der Vorsteven des Schleppers ist dazu versehen mit einem Schubadaptor, welcher funktionsmässig vergleichbar ist mit den Schubknien von für das Anwendungsgebiet speziell gebauten Schubbooten. Da jedoch ein Schlepper oder Schubboot einen annähernd konstanten Tiefgang hat, während die Kähne zwischen vollgeladenem und ungeladenem Zustand einige Meter Unterschied in Eintaugtiefe aufweisen können, ist nach genannter Publikation eine senkrechte Führungsvorrichtung angebracht am Steven des Kahnes. Bei Anwendung dieses Systems soll jeder Kahn also versehen sein mit den benötigten Führungs-und Befestigungsmitteln. Um den Schlepper steuerbar machen zu können gegenüber dem Kahn ist die Verbindung zwischen dem Vorsteven des Schleppers und den einstellbaren Schubbalken am Kahn scharnierend ausgeführt. Zur Unterstützung und Sicherung der Lenkung sind in gebräuchlicher Weise sogenannte Seitendrähte angeordnet zwischen den Steuerbord- und Backbordecken des Kahnes und den Längsseiten des Schleppers, wo diese Drähte in verlängerbarer und verkürzbarer Weise auf z.B. Winden befestigt sind. Verlängerung und Verkürzung dieser Seitendrähte ermöglichen es einen Winkel einzustellen zwischen den Mittellinien des Schleppers und des Kahnes. Ein bedeutender Nachteil der beschriebenen Vorrichtung besteht daraus, dass relativ kostbare und grosse Hilfsmittel am Kahn angeordnet sein müssen, was Kostenerhöhend wirkt, die Gefahr von Beschädigung erhöht und obendrein schwierig ist bei der Handhabung.From the Dutch patent application 7100162 a steering device is known. According to this publication (published July 20, 1971), it is intended to use a normal tugboat to push a barge, which is used as a push boat for this occasion. The front end of the tractor is equipped with a push adapter, which is functionally comparable to the push knees of push boats specially built for the area of application. However, since a tug or push boat has an almost constant draft, while the barges can have a difference of a few meters in depth between the fully loaded and unloaded state, according to the publication mentioned, a vertical guide device is attached to the stern of the barge. When using this system, each barge should therefore be provided with the necessary guide and fastening means. In order to make the tractor controllable relative to the barge, the connection between the front of the tractor and the adjustable push bars on the barge is hinged. To support and secure the steering, so-called side wires are conventionally arranged between the starboard and portboard ceilings of the barge and the long sides of the tractor, where these wires are attached in an extendable and shortenable manner to, for example, winches. Lengthening and shortening these side wires make it possible to set an angle between the center lines of the tractor and the barge. A significant disadvantage of the device described is that relatively expensive and large aids have to be arranged on the barge, which increases costs, increases the risk of damage and is also difficult to handle.

Es sind noch andere Systeme bekannt um eine scharnierende Verbindung herzustellen zwischen einem Schlepper oder Schubboot mit einem Kahn. Es betrifft dabei aber das Kuppeln und über kurze Entfernungen transportieren von unabhängig im Wasser treibenden Kähnen von z. B. dem Lash-oder Seabeetyp.Other systems are known for establishing a hinge connection between a tug or push boat with a barge. However, it concerns the coupling and transport over short distances of independently floating barges of e.g. B. the lash or seabeetype.

An Hand der nachstehenden Figurbeschreibung von einer Vorzugsausführungsform der Steuervorrichtung sollen weitere Merkmale der Erfindung näher erläutert werden.Further features of the invention will be explained in more detail with the aid of the figure description below of a preferred embodiment of the control device.

Fig. 1 zeigt eine Schubkähnekombination bestehend aus einem Schubboot 1, vor welchem sich drei Einheiten 3, 4, 5 befinden, wobei jede Einheit besteht aus zwei Bord gegen Bord aneinander gekuppelten Schubkähnen 2. Die Einheiten 4 und 5 sind in Längsrichtung starr miteinander gekuppelt, während zwischen den Einheiten 3 und 4 eine Lenkvorrichtung nach der Erfindung angeordnet ist. Ebenfalls ist zwischen dem Vorsteven des Schubbootes 1 und der Hinterseite der Einheit 5 eine korrespondierende Steuervorrichtung nach der Erfindung angeordnet.1 shows a push barge combination consisting of a push boat 1 in front of which there are three units 3, 4, 5, each unit consisting of two push barges 2 coupled to each other on board. The units 4 and 5 are rigidly coupled to one another in the longitudinal direction, while a steering device according to the invention is arranged between the units 3 and 4. Likewise, a corresponding control device according to the invention is arranged between the stem of push boat 1 and the rear of unit 5.

Die zwei Kähne 2 aus welcher eine Einheit 3, 4 oder 5 besteht, sind in bekannter Weise Bord gegen Bord gekuppelt mit Hilfe von zwei Kreuzdrähten 7 und 8 und zwei Querdrähte 10 und 11. Dies ist wiedergegeben für die Einheit 3, während es einleuchtend sein wird, dass für die Einheiten 4 und 5 etwas derartiges gilt. Dazu sind im Deck 44 der Schubkähne 2 die benötigten Klampen, Klüse, Gangspiele und/oder Winden angeordnet, welche schematisch angedeutet sind mit 15 und 16. Dazu kann z. B. 15 eine Klampe sein zum Daraufbefestigen eines Drahtes, z.B. 8 oder 9, während das andere Ende dieses Drahtes über eine mechanische Anzugvorrichtung, wie eine Winde 16, geschlagen ist. Erfahrenes Deckpersonal kann in dieser Weise, trotz Strom und Wind, mit genügender Genauigkeit Kähne neben- und hintereinander kuppeln. Absolute Genauigkeit der Ausrichtung nebeneinander und hintereinander ist dabei nicht erforderlich und kommt auch nur bei Zufall vor. Mit den Kreuzdrähten 11 und 12 und den Längsdrähten 13 und 14 sind als Beispiel in Fig. 1 die Einheiten 4 und 5 in Längsrichtung miteinander gekuppelt. Bei den bekannten Schubkähnekombinationen sind in der beschriebenen Weise alle Kähne starr miteinander gekuppelt und obendrein in derselben Weise das Schubboot starr mit der Kähnekombination. Die Steuerung einer solchen Kombination findet statt mit den gebräuchlichen Rudern oder mit drehbaren Strahldüsen 18 unter dem Schubboot 1. Vielfach ist die Kombination ausgerüstet mit einem schematisch mit 17 angegebenen Bugruder oder Bugpropeller. Eine solche Einheit ist völlig starr entlang der Mittellinie 6-6. Die Erfindung jedoch ermöglicht es, die Mittellinie 6-6 anpassen zu können an zu befahrende gekrümmte Kurse, während die starre Verbindung zwischen aufeinanderfolgenden Einheiten an einer oder mehreren Stellen umgeformt ist in eine scharnierende steuerbare Verbindung. Nach Fig. 1 findet dies statt bei der Verbindung 9 zwischen den Einheiten 3 und 4 und der Verbindung 20 zwischen der letzten Kähneeinheit 5 und dem Schubboot 1. Die Verbindung 20 zwischen dem Schubboot 1 und der Kähneeinheit wird weiter untenstehend in Detail besprochen.The two barges 2, of which a unit 3, 4 or 5 consists, are coupled in a known manner board to board using two cross wires 7 and 8 and two cross wires 10 and 11. This is shown for the unit 3, while it is obvious is that something like this applies to units 4 and 5. For this purpose, the required cleats, clubs, gang games and / or winches are arranged in the deck 44 of the barges 2, which are indicated schematically by 15 and 16. B. 15 be a cleat for attaching a wire, e.g. 8 or 9 while the other end of this wire is tied over a mechanical tightening device such as a winch 16. In this way, experienced deck staff can couple boats next to and behind one another with sufficient accuracy, despite electricity and wind. Absolute accuracy of alignment next to and behind one another is not required and only happens by chance. With the cross wires 11 and 12 and the longitudinal wires 13 and 14, as an example in FIG. 1, the units 4 and 5 are coupled to one another in the longitudinal direction. In the known push barge combinations, all of the barges are rigidly coupled to one another in the manner described and, on top of that, the pushboat is rigidly coupled to the barge combination in the same way. Such a combination is controlled with the customary oars or with rotatable jet nozzles 18 under the push boat 1. In many cases the combination is equipped with a bow rudder or bow propeller indicated schematically at 17. Such a unit is completely rigid along the center line 6-6. The invention, however, makes it possible to adapt the center line 6-6 to curved courses to be driven, while the rigid connection between successive units is transformed at one or more points into a hinged, controllable connection. 1, this takes place in connection 9 between units 3 and 4 and connection 20 between last barge unit 5 and push boat 1. Connection 20 between push boat 1 and barge unit is discussed in detail below.

Die scharnierende Verbindung 19 zwischen den Kähnen oder den Kähneeinheiten untereinander ist grösstenteils dieser gleich. Die scharnierende Verbindung 20 soll erläutert werden anhand der Fig. 1, 2, 3 und 4. Die scharnierende Verbindung 20 ist im ganzen angehängt an die Vorderseite des Schubbootes 1. Sie besteht aus einem Schubbalken 21, welcher scharnierend um die Scharnierachse S über Führungen 68 an den Steuerbord-und Backbordschubknien 50 angehängt ist. Mit Hilfe der Führungen 68 kann die scharnierende Schubvorrichtung 20 in vertikalem Sinne eingestellt werden in bezug auf den Beladungszustand der hintersten Schubkähneeinheit 5. Dabei kann der Schubbalken 21 in die gleiche Höhenlage gebracht werden mit dem Steven oder den Steven der Einheit 5. In bekannter Weise wird mit Hilfe von Längsdrähten 32 und Kreuzdrähten 35, 36 der Schubbalken 21 gekuppelt an die Einheit 5. In Längsrichtung der Kombination und in Querrichtung ist die Kupplung dadurch praktisch steif, obwohl die Drähte einige Elastizität aufweisen werden. In bezug auf die Rotation um die Längsmittellinie der Kombination des Schubbootes gegenüber der Kähneeinheit bleibt einige Bewegungsfreiheit übrig, welche nach der existierenden Praxis genügt. Auch die Deckmannschaft kann ein Schubboot, ausgerüstet mit der scharnierenden Schubvorrichtung nach der Erfindung in der ihr wohlbekannten Art und Weise weiterhin kuppeln. Zwischen dem Schubbalken 21 und dem Steven der Kähneeinheit 5 können die gebräuchlichen Stosskissen 60 angeordnet werden. Mit Hilfe von Stützen 61, 62, 63 und 64 ist der Schubbalken starr verbunden mit der senkrechten zylindrischen Säule 65. Die Mittellinie dieser Säule 65 formt die Scharnierachse S-S der Schubvorrichtung nach der Erfindung. Die Stützen 61 und 62 laufen dabei horizontal, während ihre Oberkanten in einer Ebene liegen mit den Oberkanten des Schubbalkens 21. Zwischen den Stützen 61, 62 und 63, 64 und vor der Säule 65 ist eine Öffnung anwesend, wodurch der oberste Balken 46 eines Trägerrahmens sich erstreckt. Der Trägerrahmen besteht aus zwei parallelen horizontalen Balken 46 und 66, welche über einige senkrechte Verbindungssäulen 67 zu einem starren Rahmen vereinigt sind. Mit seiner Oberseite trägt der Balken 46 des Trägerrahmens das Gewicht des Schubbalkens insgesamt dessen der Stützen und der Säule 65. Dazu können, obwohl dies nicht wiedergegeben ist in den Figuren, zwischen den Oberkanten des Balkens 64 des Trägerrahmens und der Unterkante der Stützen 61 und 62, die Reibung und den Verschleiss mindernde Bekleidungen angebracht sein.The hinge connection 19 between the barges or the barge units with one another is largely the same. The hinge connection 20 is to be explained with reference to FIGS. 1, 2, 3 and 4. The hinge connection 20 is generally attached to the front of the push boat 1. It consists of a push ball ken 21, which is hinged about the hinge axis S via guides 68 to the starboard and port thrust knees 50. With the help of the guides 68, the hinge pushing device 20 can be adjusted in a vertical sense with respect to the loading state of the rearmost barge unit 5. The push bar 21 can be brought into the same height with the stern or the stern of the unit 5. In a known manner with the help of longitudinal wires 32 and cross wires 35, 36 of the push bar 21 coupled to the unit 5. In the longitudinal direction of the combination and in the transverse direction, the coupling is thereby practically stiff, although the wires will have some elasticity. With regard to the rotation about the longitudinal center line of the combination of the push boat relative to the barge unit, there is some freedom of movement which, according to existing practice, is sufficient. The deck crew can also continue to couple a push boat equipped with the hinged push device according to the invention in the manner which is well known to them. The usual push cushions 60 can be arranged between the push bar 21 and the stern of the barge unit 5. With the help of supports 61, 62, 63 and 64 the push bar is rigidly connected to the vertical cylindrical column 65. The center line of this column 65 forms the hinge axis SS of the push device according to the invention. The supports 61 and 62 run horizontally, while their upper edges lie in one plane with the upper edges of the push beam 21. An opening is present between the supports 61, 62 and 63, 64 and in front of the column 65, as a result of which the uppermost beam 46 of a support frame extends. The support frame consists of two parallel horizontal bars 46 and 66, which are combined into a rigid frame via a number of vertical connecting columns 67. With its upper side, the beam 46 of the support frame bears the weight of the push beam as a whole of that of the supports and the column 65. Although this is not shown in the figures, this can be done between the upper edges of the beam 64 of the support frame and the lower edge of the supports 61 and 62 , the friction and wear-reducing clothing must be attached.

Der Trägerrahmen 46, 66, 67 ist an seinem Steuerbord- und Backbordende versehen mit senkrechten Führungen 68. Diese bestehen je aus einer Gabel 70, während zwischen den Zähnen der Gabel 70 zwei Sätze Laufrollen 61 drehbar um horizontale Wellen angeordnet sind. Diese Rollen laufen in gegenüber einander gelegenen Rinnen in einem H-förmigen Profil 62, das sich in senkrechter Richtung erstreckt und sich an der Vorderseite der Schubknie 50 befindet. Die Rollen 61 passen mit geringem Spiel in die Rinnen des H-Profils, während, wie Fig. 4 zeigt, die Gabel 70 in senkrechter Richtung sich so weit erstreckt, dass die zwei Sätze Rollen 61 übereinander angeordnet werden können. Eine derartige Führung 68 kann nur in senkrechter Richtung verschoben werden, während in allen anderen Richtungen Translationen und Rotationen unmöglich sind. Der Trägerrahmen 46 und 66, 67 wird dadurch gegenüber dem Schubboot 1 derart geführt, dass nur eine Bewegung in senkrechter Richtung möglich bleibt. Nach Fig. 4 wird die senkrechte Bewegung des Trägerrahmens und somit auch des Schubbalkens mit den Stützen und der Säule 65, gesteuert über die Seile 69, welche über zwei schematisch wiedergegebene Rollen 49 geführt werden zu einer schematisch wiedergegebenen Winde 51, welche am Deck des Schubbootes 1 angeordnet ist. Die Rollen 49 können mit Stühlen am Schubknie 50 montiert sein. Zwischen der Vorderseite der H-förmigen Führung 72 und des gegenüber gelegenen Teils der Gabel 70 kann ein schematisch wiedergegebenes Stosskissen angebracht sein, um einerseits den Spielraum zu kompensieren und anderseits geräuschdämpfend zu wirken. Zwischen den Enden an Steuerbordseite und Backbordseite des Schubbalkens 21 und des Balkens 46 des Trägerrahmens sind hydraulische Kolben-Zylinder-Einheiten 58 und 58a angeordnet und scharnierend bei 41 gekuppelt. Diese Zylinder 58 sind vorzugsweise doppelwirkend und können bei entgegengesetzter Bedienung den Schubbalken um die Scharnierachse S-S verdrehen gegenüber den Trägerrahmen und gegenüber dem Schubboot. Die zu übertragenden Schubkräfte zwischen dem Schubboot 1 und den Kähnen 2 können teilweise oder sogar völlig stattfinden über die Zylinder 58. Die ganze Schubkraft kann aber auch über die Stützen 61 und 64 und die zylindrische Säule 65 weitergeleitet werden zum zentralen Schubknie 73, welcher in der Mittellinie des Schubbootes senkrecht an dessen Vorsteven befestigt ist. Zur Vermeidung von Verschleiss und Verbesserung der Gleiteigenschaften kann eine Bekleidung 74 in der halbrunden senkrechten Rinne angebracht sein. Die Rinne 74 im zentralen Schubknie 73 ist so lange, dass sie über den ganzen senkrechten Verschiebungsweg der Schubvorrichtung 20 die Säule 64 stützen und führen bleibt. Dazu wird in vielen Fällen der zentrale Schubknie 73 bis zu der oder bis unter die Wasserlinie fortgesetzt mit einem schematisch wiedergegebenen Schegg 73a. In Figur 3 ist schematisch angegeben, ausgehend von einer konstanten Wasserlinie, wo sich der Kahn 2 befindet in ungeladenem und in geladenem Zustand. Links unten in Figur 3 ist mit 2' die vollgeladene Position des Kahnes wiedergegeben. Bis so weit soll also die Schubvorrichtung 20 niedergelassen werden können, welche Position massgebend ist für die senkrechte Erstreckung abwärts des Scheggs 73a.The support frame 46, 66, 67 is provided on its starboard and port end with vertical guides 68. These each consist of a fork 70, while between the teeth of the fork 70 two sets of rollers 61 are rotatably arranged about horizontal shafts. These rollers run in opposing channels in an H-shaped profile 62 which extends in the vertical direction and is located at the front of the thrust knee 50. The rollers 61 fit into the grooves of the H-profile with little play, while, as shown in FIG. 4, the fork 70 extends in the vertical direction so far that the two sets of rollers 61 can be arranged one above the other. Such a guide 68 can only be moved in the vertical direction, while translations and rotations are impossible in all other directions. The support frame 46 and 66, 67 is thereby guided relative to the push boat 1 in such a way that only movement in the vertical direction remains possible. 4, the vertical movement of the support frame and thus also the push bar with the supports and the column 65, controlled by the ropes 69, which are guided over two schematically represented rollers 49 to a schematically represented winch 51, which is on the deck of the push boat 1 is arranged. The rollers 49 can be mounted on the thrust knee 50 with chairs. A schematically represented bumper cushion can be attached between the front of the H-shaped guide 72 and the opposite part of the fork 70, on the one hand to compensate for the play and on the other hand to have a noise-damping effect. Hydraulic piston-cylinder units 58 and 58a are arranged between the ends on the starboard side and port side of the thrust beam 21 and the beam 46 of the support frame and are coupled at 41 with a hinge. These cylinders 58 are preferably double-acting and, when operated in the opposite direction, can rotate the push bar about the hinge axis S-S with respect to the support frame and with respect to the push boat. The thrust forces to be transmitted between the push boat 1 and the barges 2 can take place partially or even entirely via the cylinders 58. The entire thrust force can, however, also be transmitted via the supports 61 and 64 and the cylindrical column 65 to the central thrust knee 73, which in the The center line of the push boat is fastened vertically to the stem. In order to avoid wear and improve the sliding properties, a covering 74 can be fitted in the semicircular vertical channel. The channel 74 in the central thrust elbow 73 is so long that it supports and guides the column 64 over the entire vertical displacement path of the thrust device 20. In many cases, the central thrust knee 73 is continued up to or below the water line with a schematically represented Schegg 73a. In Figure 3 is indicated schematically, starting from a constant water line, where the barge 2 is in the unloaded and in the loaded state. At the bottom left in FIG. 3 the fully loaded position of the barge is shown at 2 '. So far the pushing device 20 should be able to be settled, which position is decisive for the vertical extension downward of the Scheggs 73a.

Es wird einleuchten, dass die Führungen 62 nach Figur 4 die gleichen vertikalen Verschiebungen erlauben sollen wie der zentrale Schubknie 73 mit seinem Schegg 73a. Es wird weiterhin deutlich sein, dass die in Figur 4 schematisch wiedergegebene senkrechte Verstellvorrichtung 49, 51, 69 durch andere bekannte Vorrichtungen ersetzt werden kann, sowie z.B. durch eine hydraulische Kolben-Zylinder-Einheit oder eine Schraubenspindel-Mutterkonstruktion. Die Wirkung der Hubvorrichtungen an Steuerbord und die an Backbord müssen naturgemäss vollkommen synchronisiert stattfinden.It will be clear that the guides 62 according to FIG. 4 should allow the same vertical displacements as the central thrust knee 73 with its Schegg 73a. It will also be clear that the vertical adjustment device 49, 51, 69 shown schematically in FIG. 4 can be replaced by other known devices, as well as, for example, by a hydraulic piston-cylinder unit or a screw spindle nut construction. The effect of the lifting devices on starboard and on port naturally have to be completely synchronized.

Der Schubbalken mit den Stützen kann, wenn nötig, auch Zugkräfte aufnehmen, welche dann über die Vorderseite der Säule 65 übertragen werden auf die horizontalen Balken 46 und 66 des Trägerrahmens und über den Trägerrahmen und die Führungen 68 weitergeleitet werden in das Schubboot 1. Auch die Zylinder 58 und 58a können Zugkräfte übertragen. Nicht destoweniger kann es sinnvoll sein, um die bekannten seitlichen Steuerungsdrähte 28b anzubringen, sowie wiedergegeben in Figur 2. In einem Punkt 30 am Kahn 2 ist das eine Ende des Drahtes 28b befestigt. Auf einem korrespondierenden Punkt an Backbord ist das Kabel 28a befestigt. Beide sind am Deck des Schubbootes 1 über Rollen 59 an Steuerbord bzw. Backbord zu einer Vorrichtung 21 geführt, welche schematisch eine Kompensationsvorrichtung wiedergibt. Die Vorrichtung 29 handhabt eine im voraus bestimmte Zugkraft in den Drähten 28a und 28b. Sie ist dazu eingerichtet, um bei Steuermanövern mit der Schubvorrichtung 20 den einen Draht zu verlängern und gleichzeitig den anderen einzukürzen. Es ist auch möglich, die Wirkung der Kompensationsvorrichtung 29 zu kuppeln mit der Steuerung der hydraulischen Kolbenzylinder 58 und 58a.The push bar with the supports can, if necessary, also absorb tensile forces, which are then transmitted via the front of the column 65 to the horizontal bars 46 and 66 of the support frame and via the support frame and the guides 68 to the push boat 1. Also the Cylinders 58 and 58a can transmit tensile forces. Nevertheless, it can make sense to attach the known lateral control wires 28b, as shown in FIG. 2. At one point 30 on barge 2, one end of wire 28b is attached. Cable 28a is attached to a corresponding point on port. Both are guided on the deck of the push boat 1 via rollers 59 on the starboard or port side to a device 21 which schematically reproduces a compensation device. The device 29 handles a predetermined tensile force in the wires 28a and 28b. It is designed to lengthen one wire and shorten the other at the same time during control maneuvers with the pushing device 20. It is also possible to couple the action of the compensation device 29 to the control of the hydraulic piston cylinders 58 and 58a.

Schliesslich kann noch bemerkt werden, dass der Trägerrahmen 46, 66, 67 mit an sich bekannten, jedoch nicht wiedergegebenen Vorrichtungen verriegelt werden kann gegen die H-förmigen Führungen 72, nachdem die gewünschte Höhenlage eingestellt worden ist. Ebenso kann die senkrechte Führungsvorrichtung 68 weggelassen werden in den Fällen wo das Schubboot 1 und die Kähne gegenüber einander immer nahezu den gleichen Tiefgang haben. Die Möglichkeit der Steuerung bleibt dabei behalten.Finally, it can also be noted that the support frame 46, 66, 67 can be locked against the H-shaped guides 72 after the desired height has been set using devices which are known per se but which are not reproduced. Likewise, the vertical guide device 68 can be omitted in cases where the push boat 1 and the barges always have almost the same draft relative to one another. The possibility of control remains.

In den Figuren 5 und 6 ist die Schubvorrichtung 19, vorgesehen um angeordnet zu werden zwischen zwei Kähnen oder Kahneinheiten, mehr detailliert wiedergegeben. Grösstenteils stimmt die Vorrichtung überein mit der Schubvorrichtung 20, vorgesehen um angeordnet zu werden am Vorsteven des Schubbootes 1. Die gleichen Teile haben die gleichen Bezugszeichen bekommen. Ist von manchen Teilen die Funktion dieselbe, jedoch die Form geringfügig abweichend, dann sind die Bezugsziffern mit 100 erhöht. Bei der Schubvorrichtung 19 wird der gleiche Schubbalken 21 verwendet und dieser ist in derselben Weise mit Längs- und Kreuzdrähten 32, 35 und 36 gekuppelt mit dem Kahn 2 oder der Kähneeinheit 3. Die Stützen 61, 62, 63 und 64 sind übereinstimmend sowie die Säule 65. Auch der Trägerrahmen 46, 65, 67 ist der gleiche, sowie dies auch der Fall ist mit den Steuerkolbenzylindern 40 und 40a. Die vertikalen Führungen 68 kommen ebenso überein, jedoch das Schubknie am Steuerbord und Backbord 150 ist derart verändert, dass dieser geeignet ist um angeordnet zu werden auf einem Vorsetzsteven 25. Dieser Vorsetzsteven 25 ist, sowie der Trägerrahmen 46, 65, 67, als Rahmen ausgeführt und umfasst einen oberen horizontalen Kastenträger 25, einen unteren horizontalen Kastenträger 75 und einige senkrechte Verbindungsträger 76. Wie die Steuerbord- und Backbordschubknie, ist das zentrale Schubknie 173 im Prinzip dem Schubknie 73 der Schubvorrichtung 20 gleich, jedoch angepasst an die Befestigung auf dem Vorsetzsteven 25, 75, 76.=Der Vorsetzsteven formt zusammen mit dem Schubbalken und dem Trägerrahmen eine integrierte Einheit. Obwohl dies nicht wiedergegeben ist in den Figuren, könnte die Winde 51 nach Figur 4 auf dem Vorsetzsteven angebracht werden um den Einheitlichkeitsgedanken der Schubvorrichtungen 19 und 20 noch weiter zu vervollkommnen. Der Vorsetzsteven wird mit Hilfe von mindestens zwei horizontalen Trägern 87 befestigt auf dem Deck eines Kahnes 2 der Kähneeinheit 5. Der Träger 78 ist über einen starken senkrechten Scharnierstift 77 drehbar befestigt an der Oberkante des oberen Kastenträgers 25 des Vorsetzstevens. Das andere Ende des horizontalen Trägers 78 ist versehen mit einer geräumigen Bohrung 83, worin ein dünnerer Schacht 82 eines Hammerkopfbolzens 80 sich hindurch erstreckt. Dieser Hammerkopfbolzen 80 passt mit seinem Kopf in eine schmetterlingförmige Aussparung 81, welche sich unter Deck des Kahnes befindet. Die schmetterlingförmige Aussparung 81 steht in Verbindung mit dem Deck über einen offenen Schlitz 81a. Mit Hilfe von Längsdrähten 82 und Kreuzdrähten kann, wie Figur 1 angibt, der Vorsetzsteven fest gekuppelt werden gegen den Steven des Kahnes 2 oder die Steven der Kähne-Einheit 4.FIGS. 5 and 6 show the pushing device 19, intended to be arranged between two barges or barge units, in more detail. For the most part, the device corresponds to the pushing device 20, intended to be arranged on the fore of the pushing boat 1. The same parts have been given the same reference numerals. If the function of some parts is the same, but the shape differs slightly, the reference numbers are increased to 100. The same push bar 21 is used in the pushing device 19 and this is coupled in the same way with longitudinal and cross wires 32, 35 and 36 to the barge 2 or the barge unit 3. The supports 61, 62, 63 and 64 are identical and the column 65. The support frame 46, 65, 67 is also the same, as is the case with the control piston cylinders 40 and 40a. The vertical guides 68 also coincide, but the thrust knee on the starboard and port 150 is modified in such a way that it is suitable for being arranged on an extension rod 25. This extension rod 25, as well as the support frame 46, 65, 67, is designed as a frame and comprises an upper horizontal box beam 25, a lower horizontal box beam 75 and some vertical connecting beams 76. Like the starboard and port thrust knees, the central thrust knee 173 is in principle the same as the thrust knee 73 of the pushing device 20, but adapted to the attachment on the attachment rod 25 , 75, 76. = The extension bar forms an integrated unit together with the push bar and the support frame. Although this is not shown in the figures, the winch 51 according to FIG. 4 could be attached to the extension rod in order to further improve the idea of uniformity of the pushing devices 19 and 20. The front post is fastened to the deck of a barge 2 of the barge unit 5 with the aid of at least two horizontal supports 87. The support 78 is rotatably attached to the upper edge of the upper box girder 25 of the front post by a strong vertical hinge pin 77. The other end of the horizontal beam 78 is provided with a spacious bore 83, through which a thinner shaft 82 of a hammer head bolt 80 extends. This hammer head bolt 80 fits with its head into a butterfly-shaped recess 81, which is located below the deck of the barge. The butterfly-shaped recess 81 communicates with the deck through an open slot 81a. With the help of longitudinal wires 82 and cross wires, as shown in FIG. 1, the attachment rod can be firmly coupled against the stern of the barge 2 or the stern of the barge unit 4.

Um den Einheitlichkeitsgedanken der Schubvorrichtung 19 noch weiter zu entwickeln, kann eine hydraulische Einheit mit eigenem Antrieb, schematisch mit 89 angedeutet in Figur 4, erstellt werden auf dem Schubbalken mit seinen Stützen zur Bedienung der Kolben-Zylinder-Einheiten 40 und 40a. Nur eine, z. B. elektrische, Bedienungsverbindung mit dem Steuerhaus des Schubbootes 1 ist dann noch erforderlich.In order to further develop the idea of uniformity of the pushing device 19, a hydraulic unit with its own drive, schematically indicated at 89 in FIG. 4, can be created on the push bar with its supports for operating the piston-cylinder units 40 and 40a. Only one, e.g. B. electrical, service connection to the wheelhouse of push boat 1 is then still required.

Da es bei Kombinationen von Schubkähnen öfter vorkommen wird, dass die Steven der zu kuppelnden Kähne sich in der gleichen Position über dem Wasserspiegel befinden, wie zwischen einem Schubboot und den mit diesem zu kuppelnden Kähnen, könnte von einer mechanischen Bedienungsvorrichtung zum Einstellen der senkrechten Position entlang der Führungen 68 abgesehen werden. Ein einmal in der gewünschten Höhenlage eingestellter Schubbalken mit Trägerrahmen kann dann fest am Vorsetzsteven befestigt sein. Auch ist es möglich, die Führungen 68 zu handhaben, jedoch diese mit Hilfe von externen Mitteln einzustellen und das Ganze dann mit nicht wiedergegebenen Mitteln zu verriegeln.Since it will be more common with combinations of pushers that the sterns of the barges to be coupled are in the same position above the water level as between a pushboat and the barges to be coupled with it, a mechanical operator could adjust the vertical position along the guides 68 are disregarded. A push bar with support frame, once set in the desired height, can then be firmly attached to the extension bar. It is also possible to handle the guides 68, but adjust them with the aid of external means and then lock the whole thing with means that are not reproduced.

Die Schubvorrichtung 19 ist lösbar an den Schubkähnen befestigt mit Hilfe der beschriebenen Vorrichtungen 79. Während des Lade- und Löschvorganges der Kähne kann die relativ kostbare Schubvorrichtung 19 dann anderswo verwendet werden. Für den Transport kann das Schubboot mit seiner eigenen Schubvorrichtung 20 dienen. Dazu ist, wie Figur 3 zeigt, die Oberseite 88 des Schubbalkens 21 und der Stützen 61 und 62 flach ausgebildet, und sind an der Unterseite der Schubvorrichtung 19 in horizontaler Ebene gelegene Träger 85 angebracht, welche schematisch in Figur 5 gestrichelt wiedergegeben sind. An der Unterseite der Tragfläche 85 ist ein abwärts heraustretender Stift 86 angebracht, welcher korrespondiert mit einer in der Ebene 88 angebrachten Öffnung 87 (Figur 2 und 3). Wenn nun das Schubboot mit seinem Schubsteven 20 unter die Schubvorrichtung 19 fährt, welche noch an der Kähneeinheit 4 befestigt ist (Fig. 1), dann können die horizontalen Ebenen sich aufeinanderlegen, wobei der Stift 86 von der Bohrung 87 aufgenommen wird. Nach dem Lösen der Hammerkopfbolzen 80, 82 der Verbindungsvorrichtung 79 kann durch das Heben der Vorrichtung 20 die Vorrichtung 19 entfernt werden von der Kähneeinheit 4 und transportiert werden, um anderswo aufs neue vorgesetzt und verwendet zu werden.The pushing device 19 is detachably fastened to the pushcarts with the help of the described devices 79. During the loading and unloading process of the barges, the relatively expensive pushing device 19 can then be used elsewhere. The push boat with its own push device 20 can be used for transport. As shown in FIG. 3, this is the top egg Te 88 of the push bar 21 and the supports 61 and 62 are flat, and are attached to the underside of the pushing device 19 in a horizontal plane 85, which are shown schematically in FIG. On the underside of the wing 85 there is a pin 86 which emerges downwards and corresponds to an opening 87 made in the plane 88 (FIGS. 2 and 3). If the push boat now moves with its push rod 20 under the pushing device 19, which is still attached to the barge unit 4 (FIG. 1), then the horizontal planes can lie on top of one another, the pin 86 being received by the bore 87. After loosening the hammer head bolts 80, 82 of the connecting device 79, by lifting the device 20, the device 19 can be removed from the barge unit 4 and transported in order to be set up and used again elsewhere.

Schliesslich zeigt Figur 5 einen gleichartigen Seitendraht 28 wie Figur 2 zeigt. Eine korrespondierende Kompensationsvorrichtung ist verbunden mit den beiden Drähten 28 an Backbord und an Steuerbord. Ihre Funktion ist übereinstimmend mit jener Beschriebenen im Zusammenhang mit den Seitendrähten 28a und 28b.Finally, FIG. 5 shows a side wire 28 of the same type as FIG. 2 shows. A corresponding compensation device is connected to the two wires 28 on port and on starboard. Their function corresponds to that described in connection with the side wires 28a and 28b.

Es wird einleuchten, dass, wenn das Schubboot 1 mit seiner Schubvorrichtung 20 gebraucht wird zum Anbringen und Entfernen der Schubvorrichtung 19 an und von einer Kähneeinheit 4, die Höheneinstellung der Schubvorrichtung 19 mit Hilfe der Schubvorrichtung 20 stattfinden kann. Eine Antriebsvorrichtung der Führungen 68 ist dann überflüssig, während eine nicht wiedergegebene Verriegelung diese dann ersetzt. Sogar könnte die Führung mit Rollen weiterhin vereinfacht werden, trotz völliger Einsatzfähigkeit der beschriebenen Steuereigenschaften der Schubvorrichtung nach der Erfindung.It will be clear that if the push boat 1 with its push device 20 is used to attach and remove the push device 19 to and from a barge unit 4, the height adjustment of the push device 19 can take place by means of the push device 20. A drive device for the guides 68 is then superfluous, while a locking device which is not shown then replaces it. Even the guidance with rollers could be further simplified, despite the fact that the described control properties of the thrust device according to the invention are fully usable.
