Abstract
PURPOSE: To prevent the inability to detect derailment caused by vibrations by using the rope guides of wire rope vibration restraining guide devices to restrain vibrations working on the gripping mechanisms of a derailment-detecting wire rope. CONSTITUTION: If a wire rope 10 for detecting derailment swings transversely during travel because of an earthquake or high winds, etc., the wire rope 10 makes contact with the inner surfaces of the rope guides 35 of guide devices 34a, 34b provided respectively at the top and bottom of the rope gripping mechanisms 14a, 14b of a balance weight 6, but its frictional force is so small that it is guided smoothly without making contact with the gripping chutes of the gripping mechanisms 14a, 14b and causing wear. If the balance weight 6 is derailed and detection rollers 15a, 1b are uncoupled from a guide rail 9, the rope gripping mechanisms 14a, 14b grip the detection rope 10 zigzag and displace the rope 10 upward or downward, and this is detected by means of a detection switch 18. Thus, vibrations working on the gripping mechanisms of the wire rope can be reduced, and derailment can be surely detected.
