Description
Die Erfindung betrifft eine mit einem beweglichen Anhängemittel, zum Beispiel einer öse, versehene Lastanschlagvorrichtung mit einem verschiebbaren Haltebolzen zur Aufnahme der Last wobei quer zu der Verschieberichtung des Haltebfaizens ein unter Federdruck stehender verschiebbarer Riegel angeordnet istThe invention relates to one provided with a movable attachment means, for example an eyelet Load attachment device with a displaceable retaining bolt for receiving the load being transverse to the Shift direction of the Haltebfaizen under spring pressure standing sliding bolt is arranged
Lastanschlagvorrichtungen diei~-r Art dienen bekanntlich dazu, mit Hilfe des verschiebbaren Haltebolzens eine Last anzuhängen. Hat der Haltebolzen die Last erfaßt dann sorgt der unter Federdruck stehende Sicherheitsriegel dafür, daß der Haltebolzen seine Ausgangslage nicht wieder einnehmen kann. Erst wenn der Sicherheitsriegel zurückgezogen wird, wird der Haltebolzen freigegeben, so daß damit auch die Last freigegeben wird.Load attachment devices of this type are known to be used to attach a load with the help of the sliding retaining bolt. Does the retaining bolt have the When the load is detected, the spring-loaded safety bolt ensures that the retaining bolt is its Can not take the starting position again. Only when the safety bar is withdrawn will the The retaining bolt is released so that the load is also released.
Da der Sicherheitsriegel mit Hilfe eines Zugseiles fernbedient wird, besteht die Gefahr, daß das Zugseil unbeabsichtigt betätigt wird, beispielsweise dann, wenn sich das Zugseil irgendwie verhakt. In diesem Falle würde die Last unbeabsichtigt freigegeben werden.Since the safety bar is operated remotely with the help of a pull rope, there is a risk that the pull rope is actuated inadvertently, for example if the pull rope somehow gets caught. In this case the load would be inadvertently released.
Der Erfindung liegt die Aufgabe zugrunde, eine Lastanschlagvomchtung zu schaffen, bei der ein unbeabsichtigtes Lösen der Last vermieden ist.The invention is based on the object of creating a load stop device in which a unintentional loosening of the load is avoided.
Nach der Erfindung wird das dadurch erreicht, daß quer zu der Verschieberichtung des Haltebolzens eine weitere verschiebbare und unter Federdruck stehende Sicherheitssperre eingeschaltet ist, deren Verschiebeweg von dem beweglichen Anhängemittel gesteuert ist.According to the invention this is achieved in that a transverse to the direction of displacement of the retaining bolt Another sliding and spring-loaded safety lock is switched on, the displacement of which is controlled by the movable hitch.
Die Ausbildung ist dabei so getroffen, daß ein Schwenkhebel vorgesehen ist, dessen eines Ende auf die Sicherheitssperre einwirkt und dessen anderes Ende mit dem beweglichen Anhängemittel in Verbindung steht Zur Verbindung dieses anderen Endes des Schwenkhebels dient dabei vorzugsweise eine Feder.The training is made so that a pivot lever is provided, one end of which on the Safety lock acts and the other end is connected to the movable hitch A spring is preferably used to connect this other end of the pivot lever.
Ist die Last angehoben, dann wird durch das dabei eintretende Verschwenken des beweglichen Anhängemittels eine Zugkraft auf den Schwenkhebel ausgeübt, wodurch der Schwenkhebel verstellt wird. Dadurch wird auch die Sicherheitssperre in die Verriegelungsstellung verschoben, so daß der Haltebolzen verriegelt ist und zwar auch dann, wenn der Sicherheitsriegel unbeabsichtigt gelöst werden sollte.Once the load has been raised, the pivoting of the movable attachment means that occurs in the process a tensile force exerted on the pivot lever, whereby the pivot lever is adjusted. Through this the safety lock is also moved into the locking position so that the retaining bolt is locked even if the safety bar should be unintentionally released.
Ist die Last abgesenkt dann ist das zwischen dem Schwenkhebel und dem Anhängemittel eingeschaltete Verbindungsmittel, zum Beispiel die Feder, wirkungslos, so daß die Sicherheitssperre unter der Wirkung ihrer Feder in die Entriegelungsstellung gelangen kann. Der Sicherheitsriegel wird dann zurückgezogen, so daß sich der Haltebolzen unter dem Drucke seiner Feder in die Ausgangsiage verschiebt. Die Lastanschlagvomchtung gibt dann die Last frei.If the load is lowered, then the one between the pivot lever and the attachment means is switched on Connecting means, for example the spring, ineffective, so that the safety lock is under the action of their Spring can get into the unlocked position. The safety latch is then withdrawn so that the retaining bolt moves into the starting position under the pressure of its spring. The load attachment device then releases the load.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt An exemplary embodiment is shown in the drawing

Fig.2 zeigt die Lastanschlagvomchtung mit entlasteter Anhängöse;Fig. 2 shows the load attachment device with relieved Attachment loop;
Fig.3 zeigt die Lastanschlagvomchtung in der Entriegelungsstellung.Fig.3 shows the load stop device in the Unlocked position.
Die insgesamt mit 17 bezeichnete Lastanschlagvorrichtung besteht aus dem Gehäuse 1, welches das geschwungene Halsstück la besitzt; in dem Gehäuse 1 ist der Haltebolzen 2 für die Last 9 verschiebbar gelagert wobei das Ende des Haltebolzens 2 in ein Endlager 18 im Halsstück la eingreifen kann. Der Haltebolzen 2 besitzt einen Bund 4, an dem sich die Feder 6 abstützt Das andere Ende der Feder 6 stützt sich bei 3 ab.The overall designated 17 load attachment device consists of the housing 1, which the has curved neck piece la; The retaining bolt 2 for the load 9 can be displaced in the housing 1 stored wherein the end of the retaining bolt 2 can engage in an end bearing 18 in the neck piece la. Of the The retaining bolt 2 has a collar 4 on which the spring 6 is supported. The other end of the spring 6 is supported turn off at 3.
Quer zu der Verschieberichtung des Haltebolzens 2 ist ein Sicherheitsriegel in Form eines verschiebbaren Sicherheitsstiftes 5 angeordnet. Dieser Sicherheitsstift 5 steht unter dem Drucke der Feder 7; er besitzt das Zugmittel 8.A safety bolt in the form of a slidable one is transverse to the direction of displacement of the retaining bolt 2 Security pin 5 arranged. This safety pin 5 is under the pressure of the spring 7; he owns that Traction device 8.
Weiterhin ist quer zu der Verschieberichtung des Haltebolzens 2 eine weitere Sicherheitssperre in Form eines verschiebbaren Sicherheitsstiftes 10 vorgesehen, der ebenfalls unter dem Drucke einer Feder 11 stehtFurthermore, a further safety lock is in the form transversely to the direction of displacement of the retaining bolt 2 a sliding safety pin 10 is provided, which is also under the pressure of a spring 11
Die Verriegelungsstellung nimr-! der Sicherheitsstift 10 mit Hilfe des Schwenkhebels 12 ein, der um die Achse 13 verschwenkbar ist. Das andere linde des Schwenkhebels 12 steht mit dem Anhängemittel 15 durch eine Feder 14 in Verbindung. Die von der Feder 14 ausgeübte Kraft ist größer als die Kraft der Feder 11. Dadurch ist erreicht daß bei belasteter Anhängöse der Schwenkhebel 12 den Sicherheitsstift 10 in die Verriegelungsstellung bringt.The locking position nimr-! the security pin 10 with the aid of the pivot lever 12 which can be pivoted about the axis 13. The other linden of the swivel lever 12 is connected to the attachment means 15 by a spring 14. The one exerted by the spring 14 The force is greater than the force of the spring 11. This ensures that the pivot lever is loaded when the suspension eye is loaded 12 brings the safety pin 10 into the locking position.
Fig.2 zeigt die Lastanschlagvorrichtung mit entlastetem Anhängemittel 15. Bei entlastetem Anhängemittel 15 ist die Feder 14 entspannt, so daß unter dem Drucke der Feder 11 der Sicherheitsstift 10 den Schwenkhebel 12 verschwenken kann, so daß der Sicherheitsstift 10 aus seiner Verriegelungsstellung gelangt.Fig.2 shows the load attachment device with relieved Attachment means 15. When the attachment means 15 is relieved, the spring 14 is relaxed, so that under the Pressures of the spring 11 of the safety pin 10 can pivot the pivot lever 12 so that the Security pin 10 comes out of its locked position.
Zum Zwecke der vollständigen Lastfreigabe wird an dem Zugseil 8 gezogen, so daß der Sicherheitsstift 5 in die Entriegelungslage, gelangt. Dadurch ist der Haltebolzen 2 völlig freigegeben, wie das in der Fig.3 im einzelnen nochmals dargestellt ist.For the purpose of the complete load release is pulled on the pull rope 8 so that the safety pin 5 in the unlocked position. As a result, the retaining bolt 2 is completely released, as shown in FIG individual is shown again.
Bei der dargestellten Ausführungsform wird die Beweglichkeit des Anhängemittels dadurch erzielt, daß das Ar.hängemittel verschwenkbar ist. Die gleiche Wirkung kann auch durch ein längsverschiebliches Anhängemittel, zum Beispiel eine Anhängeöse, erzielt werden, wobei die Anhängeöse auf einer vertikalen Achse längsverstellt werden kann.In the illustrated embodiment, the mobility of the attachment means is achieved in that the Ar. hanger is pivotable. The same effect can also be achieved by a longitudinally displaceable Hanging means, for example a hitching eye, can be achieved, with the hitching eye on a vertical one Axis can be adjusted lengthways.
