Fig. 2 zeigt das obere Tragrahmenjoch 1, an dem eine Lochplatte 10 mittels Winkeln 11 angeordnet ist. Die Lochplatte 10 trägt den Tragrahmen 4. Als Seilendverbindung ist je Seil 5 eine Seilkausche 12 vorgesehen, an der ein Tragbolzen 13 angreift. Das Seil 5 bildet in der Seilkausche 12 eine Schlaufe, wobei das Seilende am Seil 5 mittels Seilklemmen 14 festgemacht ist. Die Lochplatte 10 weist je Tragbolzen 13 eine Bohrung 15 auf, wobei der Tragbolzen 13 die Bohrung 15 durchdringt und unterhalb der Lochplatte 10 vorsteht. Der Tragbolzen 13 weist am unteren Ende ein Gewinde mit einer Mutter 16 auf, die mittels einer Gegenmutter 17 gesichert ist. Zwischen der Mutter 16 und der Lochplatte 10 ist eine Druckfeder 18 (beispielsweise mindestens eine Spiralfeder oder mindestens eine Tellerfeder) angeordnet. Bei schlaffem Seil 5 bewegt die Druckfeder 18 den Tragbolzen 13 relativ gegenüber dem Tragrahmen nach unten, wobei die Bewegung P1 des Tragbolzens 13 mittels der erfindungsgemässen Überwachungseinrichtung erfasst wird.Fig. 2 shows the upper support frame yoke 1, on which a perforated plate 10 is arranged by means of angles 11. The Perforated plate 10 carries the support frame 4. As Seilendverbindung a rope thimble 12 is provided per cable 5, on which a support pin 13 engages. The rope 5 forms in the Seilkausche 12 a loop, the rope end is fastened to the cable 5 by means of cable clamps 14. The perforated plate 10 has a bore 15 for each supporting bolt 13, wherein the carrying bolt 13 penetrates the bore 15 and protrudes below the perforated plate 10. The support pin 13 has at the lower end a thread with a nut 16 which is secured by a locknut 17. Between the nut 16 and the perforated plate 10, a compression spring 18 (for example, at least one coil spring or at least one disc spring) is arranged. When the rope 5 is slack, the compression spring 18 moves the support bolt 13 downwards relative to the support frame, the movement P1 of the support bolt 13 being detected by means of the monitoring device according to the invention.

Fig. 3, Fig. 3a, Fig. 3b zeigen die Funktionsweise der erfindungsgemässen Überwachungseinrichtung mit Reissleine 19 für ein Tragseil 5. Bei schlaffem Seil 5 bewegt sich der Tragbolzen 13 wie mit dem Pfeil P1 symbolisiert relativ gegenüber dem Tragrahmen nach unten. Zwischen der Mutter 16 und der Gegenmutter 17 ist ein Auslöseelement 20 festgeklemmt, das die gespannte Reissleine 19 bei der Bewegung P1 des Tragbolzens 13 mitnimmt. Einenends ist die Reissleine 19 an einem Fixpunkt 21 eines Bügels 22 festgemacht. Der Bügel 22 ist mittels Schrauben 23 an der Lochplatte 10 festgeklemmt. Anstelle der Schraube kann auch eine Clipverbindung vorgesehen sein. Die Mutter 16 liegt an einem Auflager 32 auf, wobei die Druckfeder 18 zwischen Lochplatte 10 und Auflager 32 angeordnet ist. Bei schlaffem Seil 5 bewegt die Druckfeder 18 das Auflager 32 und damit den Tragbolzen 13 relativ gegenüber dem Tragrahmen nach unten, wobei die Bewegung P1 des Tragbolzens 13 mittels der erfindungsgemässen Überwachungseinrichtung erfasst wird.Fig. 3, Fig. 3a, Fig. 3b show the operation of the inventive monitoring device with rip cord 19 for a support cable 5. In a slack rope 5, the support pin 13 moves as symbolized by the arrow P1 relative to the support frame down. Between the nut 16 and the lock nut 17, a trigger element 20 is clamped, which entrains the tensioned rip cord 19 during the movement P1 of the support pin 13. At one point the ripcord 19 is fastened to a fixed point 21 of a bracket 22. The bracket 22 is clamped by means of screws 23 to the perforated plate 10. Instead of the screw can also be provided a clip connection. The nut 16 rests on a support 32, wherein the compression spring 18 between the perforated plate 10 and support 32 is arranged. When the rope 5 is slack, the compression spring 18 moves the support 32 and thus the support bolt 13 relative to the support frame below, wherein the movement P1 of the supporting bolt 13 is detected by means of the monitoring device according to the invention.

Die durch die Bewegung P1 des Tragbolzens 13 verursachte Auslenkung der Reissleine 19 ist mit unterbrochener Linie dargestellt. Mit der Auslenkung der Reissleine 19 wird wie in Fig. 7 dargestellt, ein Sensor bzw. ein Grenzwerttaster 31 betätigt.The deflection of the rip cord 19 caused by the movement P1 of the support pin 13 is shown with a broken line. With the deflection of the rip cord 19, as shown in Fig. 7, a sensor or a limit switch 31 is actuated.

Wie in Fig. 3b gezeigt kann zum Ausgleich von Seilspannungsdifferenzen eine gegenüber der Druckfeder 18 wesentlich stärkere Druckfeder 33 vorgesehen sein. Die Druckfeder 33 ist am Auflager 32 abgestützt, an dem auch eine als Auslöseelement 20 dienende Fahne 25 mit Bohrung 26 angeordnet ist, wobei die Reissleine 19 durch die Bohrung geführt ist. Falls sich die Druckfeder 33 durch Seildehnung entspannt, bewegt sich der Tragbolzen 13 nach unten ohne die Reissleine 19 auszulenken. Bei schlaffem Seil 5 bewegt die Druckfeder 18 das Auflager 32 und damit den Tragbolzen 13 relativ gegenüber dem Tragrahmen nach unten, wobei die Bewegung P1 des Tragbolzens 13 mittels der Reissleine 19 erfasst wird.As shown in Fig. 3b can be provided to compensate for cable tension differences over the compression spring 18 much stronger compression spring 33. The compression spring 33 is supported on the support 32, on which a serving as a trigger element 20 flag 25 is arranged with bore 26, wherein the rip cord 19 is guided through the bore. If the compression spring 33 relaxes by rope elongation, the support pin 13 moves down without deflecting the ripcord 19. With a slack rope 5, the compression spring 18 moves the support 32 and thus the support bolt 13 relative to the support frame down, the movement P1 of the support bolt 13 is detected by means of the rip cord 19.

Fig. 4 zeigt Einzelheiten des Auslöseelementes 20 für die Reissleine 19. Das Auslöseelement 20 besteht im wesentlichen aus einer Unterlagscheibe 24, an der eine Fahne 25 mit Bohrung 26 angeordnet ist.
