Description

Die Erfindung betrifft eine Verschlußvorrichtung, insbesondere für Entladewagen, bei der die Entsperrung und Entriegelung der Verschlüsse durch Einzelwellen erfolgt.
Es sind Verschlußvorrichtungen bei Entladewagen bekannt, die aus Einzelwellen bestehen, bei denen die Sperrungen auf gesonderten Wellen sitzen. Die Betätigung und Kupplung der beiden Wellen erfordert verhältnismäßig verwickelte Einrichtungen. Es sind ferner Verschlußvorrichtungen bekannt, bei denen die Sperren auf der Verschlußwelle selbst angeordnet sind und sich gegenüber der Welle bewegen können, so daß eine Entsperrung ohne Bewegen der Welle möglich ist. Sie sind deshalb mit besonderen Sicherungen, die meistens mit Federn zusammen arbeiten, versehen. Diese Anordnung hat den Nachteil, daß eine unbeabsichtigte Entriegelung ohne Betätigung der Verschlußwelle möglich ist.The invention relates to a locking device, in particular for unloading vehicles, in which the unlocking and unlocking of the locks is carried out by means of individual shafts.
There are known locking devices for unloading cars, which consist of individual shafts in which the locks sit on separate shafts. The actuation and coupling of the two shafts requires relatively complex equipment. Locking devices are also known in which the locks are arranged on the locking shaft itself and can move relative to the shaft, so that unlocking is possible without moving the shaft. They are therefore provided with special safeguards that mostly work together with springs. This arrangement has the disadvantage that unintentional unlocking is possible without actuating the locking shaft.

ao Die Erfindung vermeidet diese Nachteile dadurch, daß die Welle in der Schließstellung die Verschlüsse zwangsläufig sperrt, und zwar derart, daß die Sperrung nur durch Bewegen der betreffenden Verschlußwelle im Sinne einer Ent- riegelung aufgehoben werden kann. Dies wird dadurch erreicht, daß die Entriegelungswelle mit Ansätzen versehen ist, die die Riegel in der Verschlußstellung festhalten. Die Verwendung solcher Ansätze hat weiter noch den Vorteil, daß sie in der Form so ausgebildet werden können, daß bei Entriegelung verschiedener Verschlüsse durch dieselbe Verschlußwelle die nicht zu entriegelnden Verschlüsse trotz der Bewegung ihrer Verschlußwelle gesperrt bleiben können. Nach der Erfindung wird auch die Entriegelung der Verschlüsse durch entsprechend geformte Ansätze herbeigeführt, was den Vorteil bietet, daß je nach der Art der der Verschlußwelle aufgezwungenen Bewegung verschiedene Ansätze auf den gleichen Riegel einwirken können. Dadurch kann die seitliche Reihenfolge, mit der die verschiedenen Verschlüsse entriegelt werden, verschieden gewählt werden, beispielsweise derart, daß zuerst die Verschlüsse einer Wagenseite entriegelt werden und erst bei einer entsprechend ausgeführten weiteren Bewegung die der anderen Seite.ao The invention avoids these disadvantages in that the shaft in the closed position the Locks inevitably locks in such a way that the lock can only be activated by moving the relevant lock shaft in the sense of a release locking can be lifted. This is achieved in that the unlocking shaft is provided with approaches that hold the bolt in the locked position. The usage such approaches also have the advantage that they can be designed in the form that when unlocking different locks by the same lock shaft the not to be unlocked Shutters can remain locked despite the movement of their shutter shaft. To The invention also includes the unlocking of the locks by means of appropriately shaped approaches brought about, which has the advantage that depending on the type of the shutter shaft imposed Movement different approaches can act on the same latch. This allows the lateral order with which the different locks are unlocked, differently selected, for example in such a way that that first the locks on one side of the car are unlocked and only on one side accordingly executed further movement that of the other side.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargesteEt. Abb.i zeigt einen Teil der Stirnansicht eines Selbstentladers mit der Verschlußvorrichtung der Klappen in Schließstellung. Abb. 2 und 3 sind Schnitte durch die Verschlußwelle der linken bzw. der rechten Wagenseite. Die entsprechenden Abb. 4, 5 und 6 stellen die Vorrichtung dar nach der durch Drehen der Welle erfolgten Entriegelung des linksseitigen Verschlusses. Durch eine weitere Gestängebewegung wird auch die rechtsseitige Klappe entriegelt. Die Verschlüsse weisen hierbei die in den Abb. 7, 8 und 9 gezeigten Stellungen auf.An embodiment of the invention is shown, for example, in the drawing. Fig.i shows part of the front view of a self-unloader with the locking device of FIG Flaps in closed position. Fig. 2 and 3 are sections through the locking shaft of the left or the right side of the car. The corresponding figures 4, 5 and 6 show the device after unlocking the lock on the left by turning the shaft. By a further movement of the rods also unlocks the flap on the right-hand side. The closures have the positions shown in Figs. 7, 8 and 9.

In allen Abbildungen ist a die Stirnwand eines Sattelwagens, δ¹ die linke Entladekläppe, δ² die rechte, welche mit Hilfe der Daumenwellen c¹, c², auf der die Hebel d¹, d^z sitzen, geschlossen gehalten werden, e ist eine Verschlußwelle, auf welcher die Sperransätze f¹, f² und die Entriegelungsansätze g¹, g² sitzen.In all figures, a is the front wall of a saddle wagon, δ ^{1 is} the left ^{unloading flap, δ 2 is} the right one, which is held closed with the help of the thumb shafts c ¹ , c ² on which the levers d ¹ , d ^z sit, e is one Lock shaft on which the locking lugs f ¹ , f ² and the unlocking ^{lugs g 1} , g ² sit.

Claims

h ¹ , h ² are bars which can be rotated in the pins i ¹ , i ^z and are pressed against the shaft e by means of the springs k ^x , k ² with the rollers P-, I ² , m ¹ , m ² are springs , n ¹ , n ² are stops which can rotate around the pins o ¹ , o ² and which have the cams φ ^χ , -ρ ^ζ , q ¹ , q ² are incisions in the bars h ¹ , W ·. r ¹ , r ^a are further unlocking approaches.

If the shaft is rotated from the position of Fig. Ι ίο to that of Fig. 4, the locking lug f ¹ releases the bolt h ¹ , and the unlocking lug g ¹ presses against the roller P- and thereby rotates the bolt h ¹ i about the pin ^1, so that the lever d ¹ is free and swings out to the right ts, whereby the stopper n ^1, φ q ¹ with the cam in the incision ¹ sets. As a result, the bolt h ^{1 is held} in the position shown in Fig. 4. The lock on the right-hand side remains locked due to the shape of the projection f ² and is only released when the shaft is rotated further in the same direction for the purpose of unlocking the lock on the right-hand side. The approach g ² lies against the role I ² and forces the bolt Ä ² ,

a5 to release lever d ^2. The bolt is caught by the stop n ^2. The release of the latch h ^1, Ä ² occurs only when during the closing of the flap, the lever d ^1, d ^2, the stops n ^l, n ² of the incisions q ^1, q ² move out, resulting in the locking of the lever result. By subsequently turning the shaft back to its starting position, the bolt is locked. An energy storage mechanism can work together with the shaft in a known manner and tends to return it from any position to the starting position. Under his influence, after a lock has been unlocked with the extension f ^l or f ² , the shaft lies against the relevant bolt h ¹ or h ^z and is only released when the lever d ¹ or d ^{2 counteracts when the relevant flap is closed} the stop w ¹ or n ² pushes, whereby the spring k ¹ or k ^z moves the bolt into its locking position. As a result, the shaft automatically locks the relevant lock.

If the lock on the right-hand side is unlocked first, the shaft is reversed twisted as before, whereupon the operations

Play in reverse order. The bars are controlled by the approaches r ¹ , r ^2. Instead of rotating the shaft in the opposite direction, the shoulders f ¹ , f ² or g ¹ , g ^{2 can also be brought} out of the area of the bars h ¹ , h ^z or the rollers P-, l ^{z by axially shifting the shaft} in order to enable the engagement of others located on the shaft with respect to this offset by certain angles.

The locks can also be unlocked according to the principle of the invention be that the shaft is not rotated for this purpose, but shifted axially. Any number of existing ones can be created by rotating the shaft beforehand by certain angles Approaches selected and brought into engagement by moving the shaft axially on the latches will. In the event that the unlocking is carried out by moving the shaft, are to provide the approaches for locking and unlocking so that a corresponding transfer the process shown on the basis of Figs. 1 to 9 takes place.
