Disclosed is a platform safety footboard device. According to the present invention, the platform safety footboard device is a train safety footboard device which is disposed in a space between a train and a platform and includes a mounting frame provided on a wall of the platform and safety footboards provided to be hinged with respect to the mounting frame and spaced apart. The platform safety footboard device comprises: a safety footboard driving unit provided on the mounting frame and driving to fold or unfold the safety footboard; a load cell provided on the mounting frame and selectively being in contact with at least a part of the safety footboard driving unit according to the driving of the safety footboard driving unit; and a control unit receiving a detection signal of the load cell to control the driving of the safety footboard driving unit. According to the present invention, through a simple power transmission structure in which the safety footboard driving unit is applied with a simple structure including one motor, one rotary arm, one load bar, a plurality of push bars and one load cell, and the load cell for passenger detection on the safety footboard is prepared in a position within the radius that can be pressed by the rotary arm, productivity can be increased.

    승강장 안전발판장치가 개시된다. 본 발명의 승강장 안전발판장치는, 전동차와 승강장 사이의 공간에 배치되고, 승강장 벽면에 설치되는 마운팅 프레임과 상기 마운팅 프레임에 대해 힌지 회전 가능하도록 마련되며 서로 이격되는 안전발판을 포함하는 전동차 안전 발판 장치로서, 상기 마운팅 프레임에 설치되어 안전발판을 접거나 펼치도록 구동하는 안전발판 구동부; 상기 마운팅 프레임에 마련되고 상기 안전발판 구동부의 구동에 따라 안전발판 구동부의 적어도 일부와 선택적으로 접촉 가능하도록 마련되는 로드셀; 및 상기 로드셀의 감지신호를 전달받아 상기 안전발판 구동부의 구동을 제어하는 제어부를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 안전발판 구동부를 하나의 모터, 하나의 회전암, 하나의 로드바, 복수의 푸시바 및 하나의 로드셀을 포함하는 간단한 구조로 적용하고 안전발판 상의 승객감지를 위한 로드셀을 회전암에 의해 가압 가능한 반경 내 위치에 마련하는 심플한 동력전달구조를 통해 생산성을 향상시킬 수 있다.
