一般にエレベータのかごが最上階に停止しているとき、
つり合いおもりと緩衝器のすき間寸法は常に規定寸法を
維持しなければならない。しかし。Generally, when an elevator car is stopped at the top floor,
The gap between the counterweight and the buffer must always maintain the specified dimensions. but.
主ロープが乗りかご及びつり合いおもりの重量により経

サを設ける案も提案されているが、費用がかさむという
ことから実用化されていなかった。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.
本発明の目的は、ピット内に保守員が入ることなく一人
作業で計測でき、しかも費用のかさむことのないエレベ
ータの主ロープ伸び量検出装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator main rope elongation detection device that can be measured by one person without the need for maintenance personnel to enter the pit, and which is inexpensive.
上記目的を達成するために、つり合いおもりの最下端と

測定装置に前記距離が所定寸法を越えた時、警告音を発
する音響装置を備えたものである。In order to achieve the above purpose, the elongation of the main rope of the elevator is detected by measuring the distance between the lowest end of the counterweight and the buffer installed at the bottom of the pit. In the detection device, a measuring device is provided at a lower end of the counterweight opposing the upper end of the buffer for measuring the distance between the counterweight and the buffer, and when the distance exceeds a predetermined dimension, It is equipped with a sound device that emits a warning sound.
つり合いおもりと緩衝器間の距離を測定する測定装置は
、緩衝器の上端と対抗するつり合いおもりの下部に設け
られ、しかも、前記距離が所定寸法を越えた時、警告音
を発するようになっている。A measuring device for measuring the distance between the counterweight and the shock absorber is provided at the bottom of the counterweight opposing the upper end of the shock absorber, and is adapted to emit a warning sound when the distance exceeds a predetermined dimension. There is.
したがって、保守員は乗りかご上に乗り、つり合いおも
り下部の測定装置の警告音を聴くことにより、つり合い
おもりと緩衝器間のすき間寸法を知ることができる。Therefore, a maintenance worker can know the size of the gap between the counterweight and the shock absorber by riding on the car and listening to the warning sound from the measuring device below the counterweight.
これにより、ピット内に入ることなく、しかも−人の保
守員で寸法測定を行なうことができる。Thereby, dimensions can be measured by one maintenance worker without entering the pit.
以下本発明の一実施例を図面に基づき説明する。 An embodiment of the present invention will be described below based on the drawings.

所定寸法例えば300 m m以下となった時警告音を
発する音響装置12とからなっている。In the figure, 1 is the car, 2 is the counterweight, 3 is the main rope for suspending the car 1 and the counterweight 2,
4 is a sheave provided in the machine room 5, and the main rope 3 is wound around this sheave 4. 6 is a floor, and 7 is a pit, and this pit 7 is provided with a buffer 8 for the car and a buffer 9 for the counterweight 2. Reference numeral 10 denotes a measuring device installed at the lower end of the counterweight 2, and this measuring device IO includes a detection part 1 consisting of an ultrasonic wave or the like that detects the distance α between the counterweight 2 and the buffer 9, and It is comprised of an acoustic device 12 that emits a warning sound when a predetermined size, for example, 300 mm or less is reached.
13は計測装置10をつり合いおもり2の下端に着脱自
在に固着させる磁石である。Reference numeral 13 denotes a magnet for fixing the measuring device 10 to the lower end of the counterweight 2 in a detachable manner.

をつり合いおもり2から取り外す。Now, however, in order to measure the gap between the counterweight 2 and the shock absorber 9, a maintenance worker rides on the car worker and attaches the measuring device ↓O to the lower end of the counterweight 2 using a magnet 13. After this, when the carmaker is operated and moved to the top floor, the counterweight 2 reaches directly above the buffer 9, and the distance between the counterweight 2 and the buffer 9 (the distance between the counterweight 2 and the buffer 9 is set to a predetermined dimension, e.g. 3
00mm or less, the acoustic device 1 of the measuring device 10
2, a warning sound is generated and it is possible to know that the distance exceeds a predetermined value. After the measurement, the measuring device 10
Remove from counterweight 2.
