Abstract

PURPOSE:To easily measure the amount of elongation of a main rope by installing a distance measuring device on the lower face of a counterweight opposed to the upper end of a shock absorber installed on the bottom of an elevator shaft, and giving an alarm when the distance up to the shock absorber measured by the distance measuring device exceeds a specified value. CONSTITUTION:A shock absorber 8 for a cage 1 and a shock absorber 9 for a counterweight 2 are provided on the bottom of an elevator shaft 7. The cage 1 and the counterweight 2 rise and fall in opposite directions by a rope 3 and sheave 4. A removable measuring device 10 is installed on the lower face of the counterweight 2 by a magnet 13, and a maintenance personnel gets into the cage 1 to move the cage 1 up to the uppermost story. A detection unit 11 detects the distance l from the shock absorber 9 to the counterweight 2, and when the distance becomes smaller than a specified value, an acoustic device 12 gives the alarm. When measurement is completed, the measuring device 10 is removed to perform the measurement about the following elevator. Elongation of the rope can thus be efficiently measured by one maintenance personnel alone.

The above-mentioned conventional technology requires two maintenance workers: one to measure the distance in the elevator pit and the other to stop the elevator car at the top floor, resulting in poor work efficiency. Furthermore, while this distance is being measured, it is necessary to stop the operation of the elevator for the safety of maintenance personnel, which causes a problem in that the operating rate of the elevator decreases accordingly. In order to solve these problems, a proposal has been made to provide a sensor inside the pit, as shown in Japanese Utility Model Application No. 58-137679, but it has not been put to practical use because of the high cost.
