Description

Die Erfindung betrifft ein Brückenverlegefahrzeug mit einer verlegbaren Brücke und einem Fahrzeugaufbau, an welchem die Brücke über eine Verriegelungsvorrichtung mit einem über einen Antrieb von einer Offenstellung in eine Verriegelungsstellung bewegbaren Verriegelungselement und einer Entlagenarretierung verriegelbar ist.The invention relates to a bridge laying vehicle with a verlegbaren bridge and a vehicle body to which the bridge via a locking device with a movable via a drive from an open position into a locking position locking element and a Entlagenarretierung is lockable.

Derartige Verriegelungsvorrichtungen dienen zum gegenseitigen Verriegeln zweier Bauteile und werden vor allem im Bereich großer und insoweit sehr schwerer Bauteile oftmals mittels hydraulischer Antriebe betrieben, über welche das Verriegelungselement zwischen einer Offenstellung und einer Verriegelungsstellung hin- und her bewegbar ist. Die hydraulischen Antriebe weisen zum Bewegen des Verriegelungselements häufig einen Hydraulikzylinder auf, dessen Kolben mit dem Verriegelungselement verbunden ist, so dass sich durch Betätigung des Hydraulikzylinders das Verriegelungselement gemeinsam mit dessen Kolben hin- und her bewegen lässt. Im Bereich von Brückenverlegefahrzeugen, bei welchem oberhalb eines mobilen Fahrzeugunterbaus eine oftmals ein erhebliches Gewicht aufweisende Brücke auf einem entsprechenden Fahrzeugaufbau angeordnet ist, wird die Brücke an dem Fahrzeugaufbau mittels einer entsprechenden Verriegelungsvorrichtung lagesicher verriegelt.Such locking devices are used for mutually locking two components and are often operated mainly in the field of large and so far very heavy components by means of hydraulic drives, via which the locking element between an open position and a locking position back and forth is movable. To move the locking element, the hydraulic drives often have a hydraulic cylinder whose piston is connected to the locking element, so that the locking element can be moved back and forth together with its piston by actuation of the hydraulic cylinder. In the area of bridge laying vehicles, in which above a mobile vehicle body a bridge often having a considerable weight is arranged on a corresponding vehicle body, the bridge is locked to the vehicle body by means of a corresponding locking device.

Als problematisch im Zusammenhang mit solchen Verriegelungsvorrichtungen hat sich erwiesen, dass diese unter normalen Bedingungen zwar eine zuverlässige Verriegelung der beiden Bauteile bewirken, also des Brückenverlegefahrzeugs und der auf diesem bevorrateten Brücke, es jedoch zu Problemen beispielsweise im Falle eines Druckabfalls innerhalb des Hydrauliksystems kommen kann. Denn durch einen Druckabfall innerhalb eines Hydraulikzylinders des Antriebs kann es dazu kommen, dass sich das Verriegelungselement ungewollt aus der Verriegelungsstellung löst und die Verriegelung zwischen den beiden Bauelementen freigegeben wird.As problematic in connection with such locking devices has been found that while they cause a reliable locking of the two components under normal conditions, so the bridge laying vehicle and stockpiled on this bridge, but it can cause problems, for example in the event of a pressure drop within the hydraulic system. Because by a pressure drop within a hydraulic cylinder of the drive, it may happen that the locking element unintentionally releases from the locking position and the lock between the two components is released.

Um dies zu verhindern, ist es aus dem Stand der Technik, also von Brückenverlegefahrzeugen, bekannt, eine zusätzliche Endlagenarretierung des Verriegelungselements in dessen Verriegelungsstellung vorzusehen. Hierzu wird üblicherweise ein zusätzliches Arretierungselement nach Art einer Endlagensicherung mit dem Verriegelungselement in Eingriff gebracht, welches ein Zurückbewegen des Verriegelungselements in dessen Offenstellung blockiert. Das Arretierungselement greift hierzu üblicherweise formschlüssig in das Verriegelungselement ein und bewirkt auf diese Weise eine mechanische Endlagenarretierung in dessen Verriegelungsstellung, so dass ein Lösen des Verriegelungselements selbst im Falle eines Druckabfalls im Hydrauliksystem nicht zu befürchten steht.To prevent this, it is known from the prior art, ie bridge laying vehicles, an additional Endlagenarretierung of Provide locking element in its locking position. For this purpose, an additional locking element is usually brought in the manner of a Endlagensicherung with the locking element into engagement, which blocks a return movement of the locking element in its open position. For this purpose, the locking element usually engages positively in the locking element and in this way effects a mechanical end position locking in its locking position, so that release of the locking element is not to be feared even in the case of a pressure drop in the hydraulic system.

Diese Art der Entlagenarretierung hat sich insoweit unter Sicherheitsaspekten zwar durchaus bewährt, weist jedoch den Nachteil auf, dass die Endlagenarretierung des Verriegelungselements entweder in konstruktiv aufwändiger Weise mittels eines zweiten Antriebs oder manuell hergestellt werden muss, was mit einem erhöhten Bedienaufwand verbunden ist.Although this type of Entlagenarretierung has been well proven in safety aspects, but has the disadvantage that the Endlagenarretierung the locking element must be made either in a structurally complex manner by means of a second drive or manually, which is associated with increased operating effort.

Aufgabe der Erfindung ist es, ein Brückenverlegefahrzeug mit einer Vorrichtung zum Verriegeln zweier Bauelemente anzugeben, bei welchen die Endlagenarretierung des Verriegelungselements in dessen Verriegelungsstellung auf einfache Weise herstellbar ist.The object of the invention is to provide a bridge laying vehicle with a device for locking two components, in which the Endlagenarretierung of the locking element in its locking position can be produced in a simple manner.

Diese Aufgabe wird durch ein Brückenverlegefahrzeug gemäß Anspruch gelöst, wobei das Verriegelungselement über ein Schraubengetriebe bewegbar ist, und wobei die Entlagenarretierung an dem Schraubengetriebe angeordnet ist.This object is achieved by a bridge laying vehicle according to claim, wherein the locking element is movable via a worm gear, and wherein the Entlagenarretierung is arranged on the worm gear.

Aufgrund des Schraubengetriebes können für die lineare Bewegung des Verriegelungselements Drehantriebe, wie beispielsweise Schwenkantriebe, verwendet werden. Die Endlagenarretierung kann im Bereich des Schraubengetriebes auf konstruktiv einfache Weise in Form einer Drehsperrung angeordnet werden, ohne dass hierzu zusätzliche Antriebe betätigt werden oder manuelle Verriegelungen verrastet werden müssen. Es ergibt sich eine zuverlässige Verriegelung der Brücke auf dem Fahrzeug. Eine konstruktiv vorteilhafte Ausgestaltung sieht vor, dass das Schraubengetriebe von einer Spiralnut und einem in diese eingreifenden Nutenstein gebildet wird. Durch Drehen der Spiralnut kann über den Nutenstein eine Zustellbewegung des Verriegelungselements in dessen Verriegelungsstellung und umgekehrt erreicht werden. In kinematischer Umkehr könnte alternativ auch der Nutenstein auf einer Kreisbahn bewegt und die Bewegung des Nutensteins in eine lineare Zustellbewegung der Spiralnut und mit dieser des Verriegelungselements überführt werden.Due to the helical gearbox rotary actuators, such as part-turn actuators, can be used for the linear movement of the locking element. The Endlagenarretierung can in the range of the screw gear be arranged in a structurally simple manner in the form of a rotation lock, without requiring additional actuators are actuated or manual locks must be locked. This results in a reliable locking of the bridge on the vehicle. A structurally advantageous embodiment provides that the helical gear is formed by a spiral groove and an engaging in this nut. By turning the spiral groove, a feed movement of the locking element into its locking position and vice versa can be achieved via the sliding block. In a kinematic reversal, the sliding block could alternatively be moved on a circular path and the movement of the sliding block can be converted into a linear advancing movement of the spiral groove and with this of the locking element.

Von Vorteil für eine gleichmäßige Zustellbewegung des Verriegelungselements ist eine Ausgestaltung, nach welcher zwei Spiralnuten und in diese eingreifende Nutensteine auf beiden Seiten des Verriegelungselements vorgesehen sind, wodurch sich ein gleichmäßiger Vorschub des Verriegelungselements erreichen lässt. Darüber hinaus können auch mehr als zwei Spiralnuten mit zugehörigen Nutensteinen gleichmäßig über den Umfang des Verriegelungselements vorgesehen werden, beispielsweise können drei, vier oder fünf derartige Anordnungen vorgesehen werden.An advantage for a uniform feed movement of the locking element is an embodiment, according to which two spiral grooves and in this engaging sliding blocks are provided on both sides of the locking element, whereby a uniform feed of the locking element can be achieved. In addition, more than two spiral grooves with associated sliding blocks can be provided uniformly over the circumference of the locking element, for example, three, four or five such arrangements can be provided.

Eine konstruktiv vorteilhafte Ausgestaltung sieht vor, dass die Spiralnut an einer über den Antrieb drehbaren Hülse und der Nutenstein an einem axialbeweglichen, gegen Verdrehen gesicherten Verriegelungselement angeordnet ist. Die Hülse kann das Verriegelungselement außenseitig umschließen. Durch Drehen der drehbaren Hülse wird die Spiralnut gegenüber dem mit dem Verriegelungselement verbundenen und insoweit verdrehgesicherten Nutenstein gedreht, so dass die Drehbewegung der Spiralnut entsprechend deren Steigung in eine Axialbewegung des Verriegelungselements überführt wird. Ein Mitdrehen des Verriegelungselements wird aufgrund der Verdrehsicherung, welche einerseits ein Verdrehen des Verriegelungselements blockiert, jedoch auf der anderen Seite Axialbewegungen des Verriegelungselements zulässt, verhindert.A structurally advantageous embodiment provides that the spiral groove is arranged on a rotatable about the drive sleeve and the sliding block on an axially movable, secured against rotation locking element. The sleeve can enclose the locking element on the outside. By rotating the rotatable sleeve, the spiral groove is rotated relative to the locking element connected to the extent and so far non-rotating nut, so that the rotational movement of the spiral groove according to their pitch in an axial movement of the locking element is transferred. A co-rotation of the locking element is due to the rotation, which on the one hand blocks a rotation of the locking element, but on the other side allows axial movement of the locking element, prevented.

Eine konstruktiv vorteilhafte Ausgestaltung sieht ferner vor, dass die Endlagenarretierung von einer endseitigen Abwinklung der Spiralnut gebildet wird, in welche der Nutenstein mit Erreichen der Verriegelungsstellung eintritt. Durch Eintreten in den abgewinkelten Endbereich der Spiralnut wird vermieden, dass der Nutenstein im Falle eines Druckabfalls im Hydrauliksystem in der Spiralnut in Richtung der Offenstellung des Verriegelungselements zurückwandert und auf diese Weise die Verriegelung unbeabsichtigt gelöst wird.A structurally advantageous embodiment also provides that the Endlagenarretierung is formed by an end-side bend of the spiral groove, in which the sliding block enters upon reaching the locking position. By entering the angled end portion of the spiral groove prevents the sliding block in the event of a pressure drop in the hydraulic system in the spiral groove in the direction of the open position of the locking element migrates back and in this way the lock is released unintentionally.

Besonders vorteilhaft ist in diesem Zusammenhang die Ausgestaltung, nach welcher die Abwinklung als Mulde ausgebildet ist. Die Ausgestaltung als Mulde erlaubt nach Art eines Bajonettverschlusses eine zuverlässige Arretierung des Nutensteins in der Verriegelungsstellung. Beispielsweise ist es infolge von Schwingungen, wie diese im Fahrbetrieb eines Brückenverlegefahrzeugs auftreten können, für den Nutenstein nicht ohne weiteres möglich, die als Mulde ausgebildete Abwinklung zu verlassen. Vorteilhaft ist die Mulde in Richtung der Offenstellung vertieft ausgebildet, wodurch sich eine zuverlässige Sicherung des Nutensteins und damit des Verriegelungselements in dessen Verriegelungsstellung ergibt.Particularly advantageous in this context is the configuration according to which the bend is formed as a trough. The design as a trough allows the manner of a bayonet lock a reliable locking of the sliding block in the locked position. For example, it is not readily possible for the sliding block as a result of vibrations, such as may occur while driving a bridge laying vehicle, to leave the bend formed as a recess. Advantageously, the trough is recessed in the direction of the open position, resulting in a reliable securing of the sliding block and thus of the locking element in its locking position.

Für eine sichere Anlage des Nutensteins in der Abwinklung wird ferner vorgeschlagen, dass der Nutenstein unter den Einfluss einer Arretierkraft in der Abwinklung anliegt. Die Arretierkraft zieht den Nutenstein in die Abwinklung hinein, wodurch die Gefahr eines ungewollten Austritts des Nutensteins aus der Abwinklung reduziert wird. Es ergibt sich ein kraftbeaufschlagter und insoweit sicherer Bajonettverschluss.For a safe investment of the sliding block in the bend is also proposed that the sliding block bears under the influence of a locking force in the bend. The locking force pulls the sliding block into the bend, whereby the risk of unwanted leakage of the sliding block from the Angling is reduced. The result is a kraftbeaufschlagter and so far safe bayonet lock.

Eine konstruktiv vorteilhafte Ausgestaltung sieht in diesem Zusammenhang vor, dass eine sich beim Bewegen des Verriegelungselements in dessen Verriegelungsstellung spannende Feder vorgesehen ist, über welche die Arretierkraft aufgebracht wird. Vorzugsweise kann es sich bei der Feder um eine Zugfeder handeln.A structurally advantageous embodiment provides in this context that an exciting when moving the locking element in its locking position spring is provided, via which the locking force is applied. Preferably, the spring may be a tension spring.

Weiterhin wird vorgeschlagen, dass zum Lösen der Entlagenarretierung eine Überwindung der Arretierkraft mittels des Antriebs erforderlich ist. Die Arretierkraft ist derart bemessen, dass diese sich nicht ohne Weiteres, beispielsweise durch auf die Verriegelungsvorrichtung wirkende Stöße oder Vibrationen überwinden lässt. Die Arretierkraft muss zunächst durch gezieltes Betätigen des Antriebs überwunden werden, so dass der Nutenstein dann aus der Abwinklung austreten und das Verriegelungselement in Richtung dessen Offenstellung bewegt werden kann.Furthermore, it is proposed that to solve the Entlagenarretierung overcoming the locking force by means of the drive is required. The locking force is such that it can not be easily overcome, for example by acting on the locking device shocks or vibrations. The locking force must first be overcome by targeted actuation of the drive, so that the sliding block then emerge from the bend and the locking element can be moved in the direction of its open position.

Eine konstruktive Ausgestaltung sieht vor, dass das Verriegelungselement über eine Verdrehsicherung verdrehgesichert ist. Über die Verdrehsicherung wird erreicht, dass das Verriegelungselement beim Drehen der Spiralnut nicht mitdreht, sondern sich axial in Richtung der Verriegelungsstellung bewegt.A structural embodiment provides that the locking element is secured against rotation by a rotation. About the rotation is achieved that the locking element does not rotate when turning the spiral groove, but moves axially in the direction of the locking position.

Im Hinblick auf einen kompakten Aufbau der Verriegelungsvorrichtung ist es von Vorteil, wenn die Verdrehsicherung an einem Endstück ausgebildet ist.With regard to a compact design of the locking device, it is advantageous if the anti-rotation is formed on an end piece.

Das Endstück kann gemäß einer weiteren Ausgestaltung einen insbesondere flanschförmig ausgebildeten Montagebereich und einen insbesondere zylindrisch ausgebildeten Führungsbereich aufweisen. Über den flanschförmig ausgebildeten Montagebereich kann die Verriegelungsvorrichtung an einem der zu verriegelnden Bauteile festgelegt werden, beispielsweise durch Verschrauben des flanschförmigen Montagebereichs mit dem Bauteil. Innerhalb des zylindrisch ausgebildeten Führungsbereichs kann das Verriegelungselement beispielsweise in einer Gleitlagerbuchse geführt hin- und herbewegt werden, wobei die Verdrehsicherung über ein sich zwischen dem Endstück und dem Verriegelungselement erstreckendes, beispielsweise bolzenförmiges Sicherungselement erreicht werden kann.The end piece can according to a further embodiment have a particular flange-shaped mounting region and a particular cylindrically shaped guide region. About the flange-shaped Mounting area, the locking device can be fixed to one of the components to be locked, for example by screwing the flange mounting area with the component. Within the cylindrically shaped guide region, the locking element can be moved back and forth guided, for example, in a plain bearing bush, wherein the rotation can be achieved via a, for example, bolt-shaped securing element extending between the end piece and the locking element.

Eine weitere Ausgestaltung sieht vor, dass zwei über den Antrieb bewegbare Verriegelungselemente auf gegenüberliegenden Seiten des Antriebs vorgesehen sind. Auf diese Weise lassen sich mit nur einen einzigen Antrieb zwei Verriegelungselemente auf gegenüberliegenden Seiten des Antriebs mit weiteren Bauteilen verriegeln, so dass sich insoweit eine doppelte Verriegelungsvorrichtung ergibt. Die beiden Verriegelungselemente können gemäß den zuvor beschriebenen Ausführungen ausgebildet und in Bezug auf den Antrieb symmetrisch auf beiden Seiten angeordnet sein.A further embodiment provides that two locking elements which can be moved via the drive are provided on opposite sides of the drive. In this way, it is possible to lock two locking elements on opposite sides of the drive with further components with only a single drive, so that in this respect results in a double locking device. The two locking elements may be formed according to the embodiments described above and arranged symmetrically on both sides with respect to the drive.

Eine weitere Ausgestaltung sieht vor, dass das Verriegelungselement der Verriegelungsvorrichtung in dessen Verriegelungsstellung in eine an der Brücke angeordnete Öffnung eingreift. Vorzugsweise weist die Brücke zwei sog. Spurträger auf, auf welchen die Reifen bzw. Ketten der die Brücke überfahrenden Fahrzeuge abrollen, wobei die Öffnungen der Brücke im Bereich der Innenseiten der Spurträger angeordnet sind. Durch Eingreifen zweier entgegengerichtet ausfahrbarer Verriegelungselemente kann die Brücke bzw. können die beiden Spurträger auf einfache Weise gegenüber dem Brückenverlegefahrzeug verriegelt werden.A further embodiment provides that the locking element of the locking device engages in its locking position in an opening arranged on the bridge. The bridge preferably has two so-called track carriers on which the tires or chains of the vehicles crossing the bridge roll, the openings of the bridge being arranged in the region of the insides of the track carriers. By engaging two oppositely extendable locking elements, the bridge or the two track carriers can be locked in a simple manner relative to the bridge laying vehicle.

Schließlich wird in Bezug auf das Brückenverlegefahrzeug weiter vorgeschlagen, dass der Fahrzeugaufbau ein im Bereich der Fahrzeugfront angeordneter Verlegearm und/oder ein im Fahrzeugheckbereich angeordneter Heckarm ist.Finally, with regard to the bridge laying vehicle, it is further proposed that the vehicle body is a laying arm arranged in the region of the vehicle front and / or a rear arm arranged in the vehicle rear area.

Fig. 1 zeigt in schematischer Darstellung eine Verriegelungsvorrichtung 1, die in einer Öffnung eines ersten Bauteils 20 festgelegt ist. Bei dem Bauteil 20 kann es sich um den Verlegearm eines Brückenverlegefahrzeugs handeln. Die Verriegelungsvorrichtung 1 ist in deren Verriegelungsstellung dargestellt, in welcher zwei zweite Bauteile 30 an dem ersten Bauteil 20 verriegelt sind, bei denen es sich um die Spurträger einer auf einem Brückenverlegefahrzeug angeordneten Brücke handeln kann. Fig. 1 shows a schematic representation of a locking device 1, which is fixed in an opening of a first component 20. The component 20 may be the laying arm of a bridge laying vehicle. The locking device 1 is shown in its locking position, in which two second components 30 are locked to the first component 20, which may be the track carrier of a bridge laying vehicle arranged bridge.

In der in Fig. 1 dargestellten Verriegelungsstellung greifen zu beiden Seiten der Verriegelungsvorrichtung 1 vorgesehene Verriegelungselemente 2 in entsprechende Öffnungen der Bauteile 30 ein, wodurch die Bauteile 20, 30 formschlüssig miteinander verriegelt werden. Die Erfindung ist jedoch nicht auf eine solche Ausbildung der Verriegelungsvorrichtung 1 beschränkt, sondern kann gleichermaßen auch bei einseitig verriegelnden Verriegelungsvorrichtungen 1 mit nur einem Verriegelungselement 2 Anwendung finden.In the in Fig. 1 illustrated locking position engage provided on both sides of the locking device 1 locking elements 2 in corresponding openings of the components 30, whereby the components 20, 30 form fit be locked together. However, the invention is not limited to such a design of the locking device 1, but can equally apply to one-sided locking devices 1 with only one locking element 2 application.

Einzelheiten der Verriegelungsvorrichtung 1 werden nachfolgend zunächst unter Bezugnahme auf die Darstellungen in den Fign. 2 und 3 erläutert.Details of the locking device 1 are described below first with reference to the illustrations in FIGS FIGS. 2 and 3 explained.

Die Verriegelungsvorrichtung 1 besteht aus einem mittig angeordneten Antrieb 3, zwei Schraubengetrieben 5 und zwei Endstücken 12, gegenüber welchen die endseitig angeordneten Verriegelungselemente 2 axial beweglich angeordnet sind.The locking device 1 consists of a centrally arranged drive 3, two screw gears 5 and two end pieces 12, against which the end arranged locking elements 2 are arranged axially movable.

Der Antrieb 3 ist unverdrehbar gegenüber dem ersten Bauteil 20 festgelegt und ebenso wie die übrige Verriegelungsvorrichtung 1 von im Wesentlichen zylindrischer Geometrie. Bei dem Antrieb 3 handelt es sich um einen hydraulischen Antrieb, der Anschlüsse 13 zum Anschluss von Hydraulikleitungen aufweist. Beispielsweise kann es sich bei dem Antrieb 3 um einen sog. Schwenkantrieb handeln, über welchen eine Drehbewegung von ein bis zwei Umdrehungen erzeugt werden kann.The drive 3 is fixed non-rotatably relative to the first component 20 and, like the rest of the locking device 1, has a substantially cylindrical geometry. The drive 3 is a hydraulic drive which has connections 13 for connecting hydraulic lines. For example, the drive 3 may be a so-called pivoting drive, via which a rotational movement of one to two revolutions can be generated.

Stirnseitig mit dem Antrieb 3 verbunden, sind zu beiden Seiten hin Scheiben 14 mit einer axial ausgerichteten Verzahnung, die in entsprechende Gegenverzahnung benachbarter Hülsen 8 eingreifen. Auf diese Weise ist sind die Hülsen 8 drehfest mit dem Antrieb 13 verbunden. Bei Betätigung des Antriebs 13 beginnen die Scheiben 14 und mit diesen die Hülsen 8 zu drehen.Front side connected to the drive 3, are on both sides towards discs 14 with an axially aligned toothing, which engage in corresponding counter-toothing of adjacent sleeves 8. In this way, the sleeves 8 are rotatably connected to the drive 13. Upon actuation of the drive 13, the discs 14 begin to rotate with them and the sleeves 8.

Entsprechend der Drehbewegung der Hülse 8 wird auch das Schraubengetriebe 5 betätigt. Dieses besteht beim Ausführungsbeispiel aus zwei auf gegenüberliegenden Seiten der Hülse 8 angeordneten Spiralnuten 6, in welchen Nutensteine 7 geführt sind. Die Spiralnuten 6 bilden eine Art Kulisse, in welcher die Nutensteine 7 geführt entlang gleiten können.According to the rotational movement of the sleeve 8 and the screw gear 5 is actuated. This consists in the embodiment of two on opposite Side of the sleeve 8 arranged spiral grooves 6, in which sliding blocks 7 are guided. The spiral grooves 6 form a kind of backdrop, in which the sliding blocks 7 can slide guided.

Die Nutensteine 7 sind fest mit dem in der Hülse 8 angeordneten Verriegelungselement 2 verbunden. Das Verriegelungselement 2 ist verdrehgesichert durch ein an dem ersten Bauteil 20 festgelegten Endstück 12 geführt, welches eine Verdrehsicherung 11 in Form beispielsweise eines in eine axiale Nut des Verriegelungselements 2 eingreifenden Nutensteins aufweist. Auf diese Weise kann das Verriegelungselement 2 axial zwischen der in Fig. 2 dargestellten Offenstellung und der in Fig. 3 dargestellten Schließstellung hin- und her bewegt werden, wobei Drehbewegungen des Verriegelungselements 2 über die Verdrehsicherung 11 blockiert werden. Das Verriegelungselement 2 ist derart angeordnet, dass es über den gesamten Verfahrweg zwischen Offenstellung und Verriegelungsstellung rein axial bewegbar ist. Drehbewegungen sind über den gesamten Verfahrweg blockiert.The sliding blocks 7 are firmly connected to the arranged in the sleeve 8 locking element 2. The locking element 2 is guided secured against rotation by a fixed to the first component 20 tail 12, which has a rotation 11 in the form of, for example, an engaging in an axial groove of the locking element 2 sliding block. In this way, the locking element 2 axially between the in Fig. 2 illustrated open position and in Fig. 3 shown closed position to be moved back and forth, with rotational movements of the locking element 2 are blocked via the rotation 11. The locking element 2 is arranged such that it is purely axially movable over the entire travel path between the open position and the locking position. Rotational movements are blocked over the entire travel path.

Bei Betätigung des Antriebs 3 wird daher entsprechend der Steigung der Spiralnut 6 der Nutenstein 7 und mit diesem das Verriegelungselement 2 in die in Fig. 3 dargestellte Verriegelungsstellung überführt. Diese Verriegelungsstellung ist auch in Fig. 1 dargestellt und wird bei dem in den Figuren dargestellten Ausführungsbeispiel nach einer halben Umdrehung der Scheibe 14 erreicht.Upon actuation of the drive 3 is therefore in accordance with the slope of the spiral groove 6 of the sliding block 7 and with this the locking element 2 in the in Fig. 3 transferred shown locking position. This locking position is also in Fig. 1 shown and is achieved in the embodiment shown in the figures after half a rotation of the disc 14.

Die Vorgänge beim Überführen des Verriegelungselements 2 von dessen Offenstellung in dessen Schließstellung sind auch den schematischen Darstellungen in den Fign. 4 bis 6 zu entnehmen.The operations during the transfer of the locking element 2 of its open position in its closed position are also the schematic representations in the FIGS. 4 to 6 refer to.

Bei Betätigung des Antriebs 3 beginnt die Hülse 8 und mit dieser die Spiralnut 6 gegenüber dem Verriegelungselement 2 und dem auf diesem angeordneten Nutenstein 7 zu drehen. Da das Verriegelungselement 2 über die Verdrehsicherung 11 gegen Verdrehen gesichert ist, behält der Nutenstein 7 seine Winkelstellung gegenüber dem feststehenden Antrieb 3 bzw. dem feststehenden Endstück 12 bei und wird über die Spiralnut 6 nach Art eines Schneckenförderers in axialer Richtung des Verriegelungselements 1 linear bewegt.Upon actuation of the drive 3, the sleeve 8 begins and with this the spiral groove 6 relative to the locking element 2 and arranged on this Nut 7 to turn. Since the locking element 2 is secured against rotation by means of the anti-twist device 11, the sliding block 7 retains its angular position relative to the fixed drive 3 or the stationary end piece 12 and is linearly moved in the axial direction of the locking element 1 via the spiral groove 6 in the manner of a screw conveyor.

In Fig. 4 ist die Offenstellung der Verriegelungsvorrichtung 1 dargestellt. Fig. 5 zeigt eine Zwischenstellung, in welcher das Verriegelungselemente 2 bereits ein Stück über das Endstück 12 hinaus bewegt wurde, die endgültige Verriegelungsstellung jedoch noch nicht erreicht hat. Diese ist in Fig. 6 dargestellt. In der Verriegelungsstellung ist das Verriegelungselement 2 über eine mechanische Endlagenarretierung 4 gegenüber ungewolltem Lösen gesichert. Hierzu ist im Endbereich der Spiralnut 6 eine Abwinklung 9 vorgesehen, welche gegenüber dem ansonsten geradlinigen Verlauf der Spiralnut 6 abgewinkelt ist. Die Abwinklung 9 ist nach Art einer in Richtung der Offenstellung gerichteten Mulde ausgebildet, in welcher der Nutenstein 7 anliegt. In dieser Stellung liegt der Nutenstein 7 nach Art eines Bajonettverschlusses in der Abwinklung 9.In Fig. 4 the open position of the locking device 1 is shown. Fig. 5 shows an intermediate position in which the locking elements 2 has already been moved a piece over the tail 12 addition, the final locking position has not yet reached. This is in Fig. 6 shown. In the locking position, the locking element 2 is secured by a mechanical Endlagenarretierung 4 against unintentional release. For this purpose, an angled portion 9 is provided in the end region of the spiral groove 6, which is angled relative to the otherwise rectilinear course of the spiral groove 6. The bend 9 is formed in the manner of a directed in the direction of the open position trough, in which the sliding block 7 is applied. In this position, the sliding block 7 is in the manner of a bayonet lock in the bend 9.

Sobald sich der Nutenstein 7 in der Abwinklung 9 befindet, kann ein Druckabfall im Hydrauliksystem selbst bei großen axialen Belastungen des Verriegelungselements 2 zu keinem Lösen der Verriegelung führen, da die Spiralnut 6 bzw. die Hülse 8 gegenüber solchen Belastungen drehblockiert ist.Once the nut 7 is in the bend 9, a pressure drop in the hydraulic system can lead to no release of the lock even with large axial loads of the locking element 2, since the spiral groove 6 and the sleeve 8 is rotationally locked against such loads.

Wie ein Vergleich der Darstellungen in den Fig. 7 und 8 zeigt, wird beim Überführen des Verriegelungselements 2 in dessen Verriegelungsstellung eine Feder 10 gespannt, so dass der Nutenstein 7 in der in Fig. 8 dargestellten Verriegelungsstellung unter dem Einfluss einer Arretierkraft F in der muldenförmigen Abwinklung 9 anliegt, vgl. auch Fig. 9. Die Arretierkraft F bildet eine von den beispielsweise bei Brückenverlegefahrzeugen auftretenden Schwingungen und Vibrationen nicht überwindbare Kraftschwelle, die durch Betätigung des Antriebs 3 überwunden werden muss, bevor der Nutenstein 7 wieder in die Spiralbahn der Spiralnut 6 eintreten kann, wodurch die Sicherheit der Endlagenarretierung 4 weiter verbessert wird. Denn sobald sich der Nutenstein 7 einmal in der Spiralnut 6 befindet, besteht bei hinreichend großer Axialbelastung des Verriegelungselements 2 die Gefahr, dass über den Nutenstein 7 die Hülse 8 und mit dieser der Antrieb 3 zurückgedreht wird, wodurch sich die Verriegelung lösen könnte.Like a comparison of the representations in the FIGS. 7 and 8 shows, when transferring the locking element 2 in its locking position, a spring 10 is tensioned, so that the sliding block 7 in the in Fig. 8 shown locking position under the influence of a locking force F in the trough-shaped bend 9 is applied, see. also Fig. 9 , The locking force F forms one of the vibrations occurring, for example, in bridge laying vehicles and Vibrations insurmountable force threshold that must be overcome by operating the drive 3, before the sliding block 7 can again enter the spiral path of the spiral groove 6, whereby the safety of Endlagenarretierung 4 is further improved. For as soon as the sliding block 7 is once in the spiral groove 6, with sufficient axial load of the locking element 2, the risk that the sleeve 8 and the drive 3 is rotated back over the nut 7, which could solve the lock.

Die Abwinklung 9 und auch der als Vorschubelement dienende Nutenstein 7 bilden eine selbsttätig in Eingriff bringbare Endlagenarretierung 4, welche eine mechanische Arretierung des Verriegelungselements 2 in dessen Verriegelungsstellung bewirkt. Selbst bei einem Druckabfall innerhalb des mit dem Antrieb 3 verbundenen Hydrauliksystems und unter dem Einfluss äußerer Schwingungen bzw. Vibrationen, wie diese bei Brückenverlegefahrzeugen beispielsweise aufgrund von Straßenunebenheiten auftreten können, wird ein Lösen des Verriegelungselements auf einfache Weise unterbunden.The bend 9 and also serving as a feed element sliding block 7 form an automatically engageable Endlagenarretierung 4, which causes a mechanical locking of the locking element 2 in its locking position. Even with a pressure drop within the connected to the drive 3 hydraulic system and under the influence of external vibrations or vibrations, as may occur in bridge laying vehicles, for example due to uneven roads, a release of the locking element is prevented in a simple manner.
