The bottom of the housing 2 8 of the signal processing unit 12 is provided, and it can be locked to the screw hole of the fixing member 30 shown in Fig. 3 by screws (not shown in the figure). FIG. 3 is a diagram ′, together with the wire rope abnormality detecting device 1 〇, constitutes a fixed member 30 of the wire rope abnormality detecting device. It is a wide L-shaped metal part formed by supporting the upper surface portion 31 of the housing for placing the signal processing unit 12 and the side surface portion 32 fixed at a predetermined position in the lifting passage. In order to fix the casing 28 with a screw lock, a plurality of through holes 3 2 are formed at the upper surface 31. Lee -10- (8) 200406356 The casing 28 is fixed in a removable state with screws 3 4. In addition, in order to leave the fixing member 30 on the rail of the carriage, a screw hole 3 5 ′ is formed on the upper surface of the side portion 32 as shown in FIG. 3 and fixed to the rail by a bracket 36 and a screw 37. In the embodiment shown in Fig. 4, the installation location of the wire rope abnormality detecting device 1 is arranged beside the winch 50.

For an elevator without a machine room, it is used to place the winch next to the top of the hoistway, fix the two ends of the main steel cable 40 to the top of the hoistway, and use the winch as the center to put the balance weight on the other side of the car. The sheave suspends it. The pair of groove wheels of the passenger compartment is arranged below the passenger compartment, and the main cable 40 is wound under the passenger compartment to tow the passenger compartment. The carriage and the counterweight will rise and fall along each carriage rail 51 and the weight rail 52.

With the lifting, for the movement route of the main cable 40 at a predetermined location in the lifting channel, although the interval and position are fixed, there will still be places where the cable will move relatively. For example, the wire rope viewed from the carriage track next to the winch or the winch supporting it, although the course of action has not changed, the wire rope has moved. This embodiment is a fixed arrangement of the wire rope abnormality detecting device 1 shown in Figs. 1 and 3 on the carriage rail 51 and the weight rail 52, respectively, beside the winch. On the edge of each track 51, the fixing member 30 is fixed by the bracket 53, and the same is true on the weight track. At this position, the movement course of the cable does not change, and the state of the cable can be accurately measured. In addition, by setting the detection device at two positions, the detection accuracy can be further improved. -11-(9) (9) 200406356 In addition, as shown in FIG. 5A, the fixing system of the detection device 1 can directly use the bracket 62 to mount the fixing member 30 on the wall surface 61 of the lifting passage 60, or As shown in FIG. 5B, a plurality of detection devices 1 are installed on the same boarding rail 5 丨. Fig. 6 shows an example of deformation of the fixed member. As shown in FIG. 6A, 'the wire rope abnormality detecting device 10 is mounted on a base 38 provided on the upper surface 31 of the fixing member 30. The base 38 is mounted so as to be freely rotatable by a shaft 39 fixed to the upper portion 31, and is designed to be rotatable by a steel index guide when the groove of the wire rope abnormality detection machine contacts the wire rope. As shown in FIG. 6B, the surface 50b of the main sheave 50a and the surface 73a of the passenger compartment 73 may sometimes have different angles in the hoistway, and the parallel planes of the plurality of steel cables 40 will be twisted. For example, in order to avoid the arrangement of the sheaves 7 2, 7 3 (for example, Fig. 10) located on the center of both sides of the passenger compartment, since the positions of these sheaves deviate from the center of the passenger compartment, Therefore, the surface 50b of the main sheave 50a and the opposite surface 7 3a of the passenger compartment sheave will not become parallel. Therefore, if the passenger car rises to the side of the winch, the distortion of the parallel plane of the cable will become larger, and the cable 40 and the groove 14 of the detector will contact each other. As illustrated in Fig. 6a, 'If the detection section 11 is installed to be able to rotate freely on the fixed member 30, it will follow the wire rope and change the position of the groove, so that the groove can be prevented from being damaged. Wear of hope. Fig. 7 is a schematic diagram showing another embodiment of the detecting section n of the wire rope abnormality detecting device. FIG. 7A shows the use of a plurality of main cables 40 composed of a plurality of parallel cables 40a, 40b, 40c -12- (10) 200406356, and 40d. Here, two detection units are used. 11 a and 1 1 b are correspondingly arranged on the fixed member 30 in parallel. The signal processing sections 12a, 12b can be combined with the individual detection sections, and one signal processing section (12a or 12b) can also be used to process the signals of the two detection sections. When the diameters of the main ropes are different from each other, or when the amount of steel is more than the groove of the detection section, the measurement can still be performed simultaneously, and the type can shorten the measurement time.

Fig. 7B shows an implementation form of the abnormality detecting unit 1 1 c that includes a plurality of steel cables 40a, 40b, 40c, and 40d together and uses one groove 14e to check the abnormality. Each space between a plurality of steel cables moving in parallel is about 3 mm. For example, it is not easy to insert the partition plate 14a 'between the grooves 14 shown in Fig. 1 into a narrow steel cable without contact. With the comprehensive inspection shown in this form, measurement can be performed easily. When an abnormal part is found, it can be detected with high accuracy after inspecting the part more precisely.

In the embodiment shown in FIG. 11, the wire rope abnormality detecting device 1 is arranged beside the sheave 76 of the balance weight 75. In the case of an elevator with no machinery room and the winch is located beside the top of the hoistway, because one end of the steel cable is supported by the ceiling or its vicinity, it is necessary to measure the distance between this support 77 and the balance weight 75 When the wire rope 40 is used, the detection device 1 can be arranged on the balance weight 75 to make the abnormality detection measurement feasible. The embodiment shown in Fig. 12 is designed as a wire rope abnormality detection device! After taking out the output through the cable 81, using the control panel 80 installed in the lifting passage 60, the condition can be monitored in the information center 83 after being taken out through a communication network 82 such as a telephone line. By constantly setting up the wire rope abnormality detection device 1 ', it is possible to try to prevent and maintain and streamline manpower that can cope with abnormality from time to time. Regardless of this embodiment or the embodiment shown in Fig. 1, when detecting the number of abnormalities set in the signal processing unit -14- (12) 200406356, it is required to have the number of recorded abnormalities recorded. The memory function of 利用 can use this abnormal data record to judge the abnormal action of the cable. In this embodiment, the record of this constant 异 is transmitted to the remote control terminal of the information center 83, and it is possible to try to prevent and maintain the elevator operation.
