The invention discloses an anti-overspeed and anti-reversion device of an escalator or a moving sidewalk, the device comprises a transmission assembly, an encoder and a fixing frame, the transmission assembly is used for driving the encoder to rotate, and the fixing frame is used for fixing the encoder on a folding side plate; the transmission assembly comprises a first transmission part and a second transmission part, the first transmission part and the second transmission part rotate synchronously, and the first transmission part is fixedly connected with a rotating shaft of the encoder. The second transmission part is fixedly connected with a transmission shaft between step chain driving devices or pedal chain driving devices on the two sides of the escalator or the moving sidewalk. According to the anti-overspeed and anti-reversion device, a high-speed shaft of a motor does not need to be detected, and a driving device of a step chain or a pedal chain does not need to be detected either, so that the encoder can send out a pulse signal conforming to the actual situation, and the overspeed or reversion phenomenon of an escalator or a moving sidewalk is effectively detected and stopped.

    本发明公开了一种自动扶梯或自动人行道的防超速及防逆转装置,该装置包括传动组件、编码器及固定架,所述传动组件用于带动所述编码器转动,所述固定架用于将所述编码器固定在合拢边板上;所述传动组件包括第一传动部和第二传动部,所述第一传动部与第二传动部同步转动,所述第一传动部与所述编码器的转轴固定连接,所述第二传动部与所述自动扶梯或自动人行道的两侧梯级链或踏板链驱动装置之间的传动轴固定连接。本发明的防超速及防逆转装置,无需对电机的高速轴进行探测,也无需对梯级链或踏板链的驱动装置进行探测,使得编码器能够发出与实际情况相符的脉冲信号,有效检测出自动扶梯或自动人行道的超速或逆转现象并制停。
