Swing door apparatus for subway gate

The present invention relates to a swing door device arranged in a subway gate, the swing door device comprising: a gate body (10) having a fee settlement function; a shutter (30) rotatably supportedby forming a drive shaft (31) on one side of the gate body (10); a locking means (40) for applying the electromotive force of the coil pipe (45) to the shutter (30) to maintain a closed or forward/reverse open position; and a control means (50) for controlling the gate body (10), the shutter (30), and the locking means (40) in accordance with a set algorithm. Thus, when there is a sudden increasein passengers to be handled in a subway gate, the risk of colliding with the door is reduced even if a power failure or malfunction occurs, thereby improving convenience and safety. 本发明为设置于地铁闸机的扇门装置，其特征在于，包括：闸机本体(10)，具有费用结算功能；挡板(30)，在上述闸机本体(10)的一侧形成驱动轴(31)来以能够旋转的方式被支撑；锁定单元(40)，向上述挡板(30)施加螺旋管(45)的电动力来维持封闭或正逆方向开放位置；以及控制单元(50)，按设定的算法控制上述闸机本体(10)、挡板(30)及锁定单元(40)。由此，在地铁闸机的处理对象搭乘人员剧增的情况下，即使发生停电或错误动作，也减少与门碰撞的危险性，从而提高便利性和安全性。
