The present invention relates to a reverse rotation preventing apparatus for an escalator, and more particularly, to a reverse rotation preventing apparatus for an escalator, which can be easily installed in a conventional escalator and improve the reliability of the reverse rotation prevention of the escalator by being mechanically operated by a pawl ratchet wheel method. The reverse rotation preventing apparatus for an escalator includes a ratchet gear module coupled and fixed to a rotary shaft for driving the escalator, a driving module for limiting the rotation of the ratchet gear module, a solenoid unit for operating the driving module, and a reverse rotation detecting unit for detecting the reverse rotation of the rotary shaft. The ratchet gear module includes a ratchet wheel coupled to the outside of the rotary shaft, a ratchet fixing flange, a ring-shaped bushing, a brake lining in contact with the outer side of the ratchet fixing flange, first and second side flanges coupled to the rotary shaft, and a main bracket.
본 발명은 에스컬레이터용 역회전 방지 장치에 관한 것으로, 보다 상세하게는 기존 에스컬레이터에 용이하게 설치할 수 있도록 하면서도, 폴 래칫 휠 방식(Pawl ratchet wheel method)에 의해 기구적으로 작동되어 에스컬레이터 역회전 방지의 신뢰성을 향상시킬 수 있도록 하는 에스컬레이터용 역회전 방지 장치에 관한 것이다.
