Abstract

PROBLEM TO BE SOLVED: To provide a detection method for degradation of a main rope in an elevator which can easily detect the local degradation of the main rope. SOLUTION: Call register signals of a car 5 to be output from each of call buttons 13a-13e of the car 5 are input in a processor 14 in a control unit 3, and also the travelling times of the car 5 in regions Aa-Ae among floors are calculated by the processor 14 based on the call register signals. The obtained travelling record data of the car 5 are compared with predetermined decision values for degradation to specify the region between certain floors where the car 5 travels most frequently, for example, a region Aa between a first floor 12a and a second floor 12b. Then, the local degradation of a main rope 7 is inspected by confirming a portion of the main rope 7 which corresponds to the region Aa.

2. Description of the Related Art FIG. 6 is a longitudinal sectional view showing the general structure of a general elevator. In general, as shown in FIG. 6, an elevator is provided with a hoisting machine 2 and a control unit 3 in an upper machine room 1, and a hoistway 4 is formed below the upper machine room 1. The car 5 and the counterweight 6 move up and down. A plurality of main ropes 7 suspending the car 5 and the counterweight 6 are wound around a hoisting sheave 8 rotating together with the hoisting machine 2 and a deflector wheel 9, and the car 5 and the counterweight 6 are provided at both ends. Are connected to each other. The main rope 7 is a hoisting sheave 8
The driving force of the hoisting machine 2 is transmitted to the car 5 and the counterweight 6 by the frictional force of the hoisting machine, and as a result, the car 5 and the counterweight 6 move up and down in the hoistway 4 in directions opposite to each other. ing. One end of the compensating rope 10 and one end of the tail cord 11 are connected to the bottom of the car 5, and the other end of the compensating rope 10 is connected to the bottom of the counterweight 6.

要がある。
In the elevator configured as described above, the main rope 7 supports the car 5 and the counterweight 6, and the main rope 7 transmits the driving force of the hoisting machine 2. Since the main rope 7 is very important, it is necessary to prevent a breakage accident of the main rope 7 by checking the state of deterioration of the main rope 7.

[0004] Therefore, conventionally, a maintenance person visually checks the main rope 7 at every elevator traveling time to check the deterioration state. However, in this visual inspection method, it is necessary for the maintenance staff to visually check the entire length of the main rope 7 in order to determine which part of the main rope 7 has deteriorated, which requires considerable labor and time. there were. In addition, since the above-described periodic inspection is performed every elevator traveling time, the inspection interval is not necessarily the inspection interval that matches the traveling state of the elevator. For example, when the traveling frequency of the elevator is relatively small, useless inspection may be performed. If the frequency of elevator travel is relatively high, there is a concern that inspection of the main ropes 7 may be delayed.

Therefore, as one means for solving such a conventional problem, as described in, for example, JP-A-6-286957, the rope grooves of the hoisting machine 2 and the deflecting wheel 9 are connected to each of the main ropes 7. By measuring the electrical resistance value of the main rope 7 in an insulated state, and comparing the measured value with the initial value and the electrical resistance value of another rope, a time-dependent change of the main rope 7 is detected. A method has been proposed for detecting deterioration of the main rope 7 such as wire breakage.
