Disclosed is a safety foothold device for a platform. A purpose of the present invention is to provide the safety foothold device for a platform, capable of largely reducing manufacturing costs for a whole device and preventing an increase in costs for a repair and component replacement. The safety foothold device for a platform includes: a mounting frame (100) installed on a wall of a platform; a safety foothold (200) installed to rotate by a hinge on the mounting frame; and a safety foothold operating unit (300) operating to fold or unfold the safety foothold by being installed in the mounting frame (100) and having one end which can support the lower part of the safety foothold (200). The safety foothold operating unit (300) includes multiple push bars (340) capable of rotating on the mounting frame (100) according to operation of a motor. The multiple push bars (340) are integrally connected by a push bar connection rod (360) and operate at the same time. A pair of hitting rotation plates (500) are installed at a position spaced from both ends of the safety foothold (200). When a motor car stopping on a track starts forward driving or backward driving, the hitting rotation plate (500) is folded by rotating by being hit by a side of the motor car. Therefore, the hitting rotation plate (500) can be folded in a rotation direction to the left and right to correspond to a forward driving direction or a backward driving direction of the motor car. A foothold compulsion operation unit (700) connects the push bar connection rod (360) of the safety foothold operating unit (300) and the hitting rotation plate (500). A folded movement or an unfolded movement of the hitting rotation plate (500) and the safety foothold (200) are linked to each other. The safety foothold (200) is compulsorily folded by being linked to the rotation of the hitting rotation plate (500) due to the forward driving or the backward driving of the motor car stopping on the track when the hitting rotation plate (500) and the safety foothold (200) are unfolded.

    승강장 안전발판장치가 개시된다. 본 발명의 승강장 안전발판장치는, 승강장 벽면에 설치되는 마운팅 프레임(100)과, 상기 마운팅 프레임에 대해 힌지 회전 가능하도록 마련되는 안전발판(200)과 상기 마운팅 프레임(100)에 설치되어 안전발판을 접거나 펼치도록 구동하며, 일단이 상기 안전발판(200)을 하측에서 지지 가능하며 모터 구동에 따라 상기 마운팅 프레임(100)에 대해 힌지 회전 가능한 복수의 푸시바(340)를 구비하는 안전발판 구동부(300)를 포함하고, 상기 복수의 푸시바(340)는 푸시바 연결봉(360)에 의해 일체로 연결되어 동시에 구동된다. 타격회전판(500)은 상기 안전발판(200)의 양단과 이격된 위치에 한 쌍이 설치되며, 선로에 정차 중인 전동차의 전진 또는 후진 주행 시작시 전동차 측면에 의해 타격되어 회전되어 접히되, 전동차의 전진 또는 후진 주행 방향과 대응되게 좌우 회전 방향으로 모두 접힐 수 있다. 발판 강제 구동부(700)는 상기 타격회전판(500)과 상기 안전발판 구동부(300)의 푸시바 연결봉(360) 사이를 연결하여, 상기 타격회전판(500)과 안전발판(200)이 접거나 펼쳐지는 동작이 서로 연동하도록 하되, 타격회전판(500)과 안전발판(200)이 펼치진 상태에서 선로에 정차 중인 전동차의 전진 또는 후진 주행에 의한 상기 타격회전판(500)의 회전에 연동하여 상기 안전발판(200)이 강제적으로 접히도록 한다.
