[0046] figure 1 It is a front view ( figure 1 The area sensor 52 is not present in the elevator 10, and the elevator 10 has the area sensor 52 as a constituent element of the rope swing detection device. figure 2 is a right side view of the elevator 10 .
[0047] Such as figure 1 with 2 As shown, the elevator 10 is a rope-driven elevator using a traction method as a driving method. A machine room 16 is provided at a portion of the building 14 above the uppermost portion of the hoistway 12 . A traction machine 18 and guide wheels 20 are arranged in the machine room 16 . A plurality of main ropes are wound around the sheave 22 and the guide pulley 20 constituting the hoisting machine 18 . The multiple master ropes are referred to as "master rope group 24" (in addition, in figure 1 There is no record of the correct root number of the main rope set 24).
[0048] One end of the main rope set 24 is connected with a car 26 , and the other end is connected with a counterw...

[0107] In the case where the car 26 is located above the area sensor 52, since the accompanying cable 34 exists in the assumed coordinate area R1, in the above-mentioned modified example of the first embodiment, it is set to be excluded from the assumed coordinate area R1. In order to obtain the tentative coordinate region R2 of the region where the cable 34 is supposed to exist (cable exclusion region), as described above, the amplitude calculation unit 508 excludes the coordinates corresponding to the cable 34 from the target coordinates for calculating the amplitude.
[0108] On the other hand, in the second embodiment, when the car 26 is positioned above the area sensor 52, objects that may exist in the assumed coordinate region R1, that is, in order to compensate the rope portion 32A and the accompanying The coordinates of the cable 34 excluding the accompanying cable 34 are used to compensate for the differences in the dimensions (diameters) of the cables C1 to C8 and the...

[0123] In the first embodiment and the second embodiment, the vibration amplitude when the car-side main rope portion 24A or the car-side compensating rope portion 32A occurs in the vicinity of the installation position of the area sensor 52 is detected. In the third embodiment, further, after the above-mentioned yaw converges to a certain degree, before the elevator starts running again, the slope of the car-side main rope portion 24A or the car-side compensating rope portion 32A is detected. Even if the yaw has converged, the main ropes M1-M8 and the compensation ropes C1-C8 may still be caught in other machines or other equipment in the hoistway 12 while the yaw continues. At this time, under normal circumstances, the ropes to which the main ropes M1-M8 and the compensation ropes C1-C8 extending in a substantially vertical direction are suspended are abnormally inclined relative to the vertical direction. Therefore, in the third embodiment, the slope of the rope is detected...
