The present invention relates to an automatic locking device for a safety door of a construction lift and more particularly, to a locking means for an opening and closing device applied to a safety door on each floor of a building corresponding to a construction lift. In detail, the automatic locking device for a safety door, which has a safety door frame part in which a safety door opened and closed in response to the elevation of a construction lift is installed on each floor of a building, and a rotating angle unit installed to rotate according to the opening and closing of the safety door at one side of the safety door frame part, comprises a rotation control means for controlling a rotation angle of an angle fixing means according to an approach of the lift. The rotation control means includes: a rotation shaft configured to rotate in the safety door frame part; a weight stopper coupled to the rotation shaft and configured to be lowered by its own weight and rotate the rotation shaft so that the rotation angle unit does not rotate; a rotating portion configured to protrude from the rotating shaft so as to face the weight stopper; a wire coupled to an end of the rotating portion; and a traction portion provided in the safety door frame part to pull the other end of the wire that is not coupled to the rotating portion so that the weight stopper rotates the rotation shaft not interfering with the angle fixing means. According to the present invention, a number of effects such as simple installation and high operational reliability can be expected.
본 발명은 건설용 리프트의 안전문 자동 잠금장치로서, 이를 보다 상세히 설명하면 건설용 리프트에 대응되는 건축물의 층별 안전문에 적용되는 개폐장치의 잠금수단을 제공코자 한 것으로서, 상기 본 발명은 구체적인 수단으로 건설용 리프트의 승강에 대응하여 개폐되는 건물의 층별 안전문이 설치된 안전문틀부과, 안전문틀부의 일측에서 안전문의 개폐에 따라 회동되도록 설치된 회동앵글을 갖는 안전문 자동 잠금장치에 있어서, 리프트의 접근에 따라 앵글고정수단의 회동각도를 제어하는 회동제어수단이 포함되며, 회동제어수단은, 안전문틀부에서 회동되도록 축설 구성된 회동축과, 회동축에 결합되어 자중에 의해 회동축을 회전시켜 하향되어 회동앵글이 회전하지 않도록 구성된 중량스토퍼와, 중량스토퍼에 대향되도록 회동축에 돌출되게 구성된 회동부와, 회동부의 단부에 결합 구성된 와이어와, 회동부에 결합되지 않은 와이어의 타단을 당겨 중량스토퍼가 앵글고정수단에 간섭되지 않게 회동축을 회동시키도록 안전문틀부에 구성된 견인부가 포함된 것을 특징으로 하며, 이러한 본 발명에 의해 설치가 간편하면서도 작동 신뢰도가 높은 등 다수의 효과를 기대할 수 있는 발명이다.
