Title
(EN) ANTI-REVERSING DEVICE FOR ESCALATOR
(KO) 에스컬레이터 역주행 방지장치
Abstract
(EN)
The present invention relates to an anti-reversing device for an escalator. The present invention includes: a latch wheel (220) fixed to a driving shaft (142), on which includes a driving wheel (140) to move a footrest while rotating by the power transmitted through a driving motor (100) is installed, to rotate together with the driving shaft and stopping the rotation of the driving wheel (140) by being stopped through a stopper when a latch pole (242) is hooked; and a solenoid (280) controlling the latch pole (242) to be hooked on the latch wheel (220) when the driving wheel (140) is abnormally rotated. Since the operation of the solenoid (280) makes the latch pole (242) hooked on the latch wheel (220) when the driving wheel (140) is abnormally rotated, the rotation of the latch wheel (220) is stopped and the operation of the driving wheel (140) is suspended, and thus, if the escalator is abnormally operated, the rotation of the driving wheel is immediately stopped to suspend the operation of the escalator, so the present invention can prevent the escalator from being reversely operated.

본 발명은 에스컬레이터 역주행 방지장치에 관한 것으로서, 구동모터(100)를 통해 동력을 전달받아 회전하면서 발판을 이동시키는 구동휠(140)이 설치되는 구동축(142)에 고정되어 같이 회전하되, 래치폴(242)이 걸리면 스토퍼에 의해 회전이 멈춤으로써 구동휠(140)의 회전을 멈추게 하는 래치휠(220), 상기 구동휠(140)이 비정상적으로 회전할 때 상기 래치폴(242)이 상기 래치휠(220)에 걸리도록 제어하는 솔레노이드(280)를 포함하여, 구동휠(140)이 비정상적으로 회전하면 솔레노이드(280)가 작동하여 래치폴(242)이 래치휠(220)에 걸리게 함으로써 래치휠(220)의 회전을 멈추고 그 결과 구동휠(140)의 작동을 정지시켜 에스컬레이터에 비정상적인 작동 상황이 발생하는 경우 즉각적으로 구동휠의 회전을 멈추어 에스컬레이터의 작동을 멈춤으로써 역주행을 방지하여 줄 수 있게 되는 에스컬레이터 역주행 방지장치에 관한 것이다.
