Fig. 3 is a view showing the fixing member 30 which constitutes the cable abnormality detecting device together with the wire rope abnormality detecting machine 1 . This is a wide L-shaped metal part, and is formed by carrying the signal processing unit 1, 2 housing fringe upper surface portion 31, and side surface portion 32 fixed at a predetermined position in the elevating passage. In order to allow the housing 28 to be screwed and fixed, a plurality of through holes 32 are formed in the upper surface portion 31, and the housings 28 are fixed in a detachable state by screws 34. Further, in order to leave the fixing member 30 on the carriage rail, the side portion 3 2 is formed with a screw hole 35 as shown in Fig. 3, and is fixed to the rail by the bracket 36 and the screw 37. In the embodiment of Fig. 4, the installation location of the cable abnormality detecting device 1 is disposed beside the winch 50. In the case of an elevator without a mechanical room, the winch is placed beside the top of the hoistway, and the two ends of the main cable 40 are fixed to the top of the hoistway, centered on the winch, and placed on the other side of the passenger compartment with a counterweight. The sheave lifts it up.

The base 38 is mounted for free rotation by means of a shaft 39 fixed to the upper portion 31, which is designed to be guided by the cable when the cable of the cable abnormality detecting machine contacts the cable. As shown in Fig. 6B, the surface 50b of the main sheave 50a and the surface 73a of the passenger compartment 73 may have different angles in the hoistway, and the parallel faces of the plurality of steel cables 40 may be twisted. For example, in order to avoid the arrangement of the sheaves 72, 73 (for example, FIG. 10) of the rails 51 located on the sides of the two sides of the passenger compartment, since the positions of the sheaves deviate from the position of the center of the passenger compartment, the main The surface 50b of the sheave 50a does not become parallel with the opposite passenger compartment sheave surface 73a. Therefore, when the carriage is raised to the side close to the winch, the twist of the parallel faces of the cable will become larger, and the cable 40 and the groove 14 of the detector will contact each other. As explained in Fig. 6A, if the detecting portion 1 1 is mounted to be freely rotatable on the fixing member 30, it will follow the movement of the cable and change the position of the groove, thus preventing the occurrence of the groove from being undesired.

The signal processing units 1 2a and 1 2b can be combined with the individual detecting units, and the signal processing units (1 2a or 1 2b) can be used to process the signals of the two detecting units. When the diameters of the cable of the main cable are different from each other, or when the number of cables is more than the number of grooves in the detecting portion, the measurement can be performed at the same time, and the measurement time can be shortened. Fig. 7B is a view showing an embodiment in which the plurality of wires 40a, 40b, 40c, and 40d are collectively joined, and the abnormal detecting portion 11c is inspected by one groove L4e. The spacing between the plurality of parallel cables is about 3 mm. For example, the partitions 14 4 a between the grooves 14 shown in Fig. 1 are inserted into the narrow cables without contact. It is easy to use the total inspection shown in this form to make measurement very simple. When an abnormal portion is found, high-accuracy anomaly detection can be achieved by more closely checking the portion.
