PROBLEM TO BE SOLVED: To provide a chain elongation detection device for a passenger conveyor capable of detecting an elongation amount of a chain accurately and automatically, and a passenger conveyor.SOLUTION: A chain elongation detection device 1 for a passenger conveyor comprises: a driving wheel 17 rotated by a driving source; a driven wheel 13 rotated by a chain 18 by a driving force of the driving wheel 17; bodies 27, 28 to be detected which are provided in the driving wheel 17 and the driven wheel 13 respectively; sensors 29, 30 which are fixed to a main frame of a passenger conveyor for each body 27, 28 to be detected and detect rotary passage by circulation of the bodies 27, 28 to be detected; and a calculation part 31 for calculating a difference of rotary passage timing from the sensors 29, 30 and calculating an increment of the difference before and after a time lapse of the passenger conveyor. The calculation part 31 calculates an elongation amount of the chain 18 on the basis of the increment, an angular speed of the driving wheel 17, and a rotation diameter of the driven wheel 13.SELECTED DRAWING: Figure 2

    【課題】チェーンの伸び量を精度良く自動的に検出可能な乗客コンベア用チェーン伸び検出装置および乗客コンベアを提供する。【解決手段】本発明の一実施形態によれば、駆動源により回転する駆動輪17と、この駆動輪17の駆動力によりチェーン18によって回転する従動輪13と、これらの駆動輪17および従動輪13にそれぞれ設けられた被検出体27、28と、被検出体27、28毎に乗客コンベアの主枠に対して固定され被検出体27、28の周回による回転通過を検出するセンサ29、30と、センサ29、30からの回転通過タイミングの差を求め、乗客コンベアの経時前後におけるその差の増加量を求める算出部31とを備え、算出部31は増加量、駆動輪17の角速度および従動輪13の回転径によってチェーン18の伸び量を算出する乗客コンベア用チェーン伸び検出装置1が提供される。【選択図】図2
