The present invention relates to an automatic locking device for a safety door of a lift for construction. More specifically, an objective of the present invention is to provide a locking means of an opening and closing device applied to a safety door for each floor of a building corresponding to a lift for construction. Specifically, the automatic locking device for a safety door having a rotating angle installed to be rotated by opening and closing a safety door on one side of a safety door frame, on which the safety door for each floor of a building opened and closed in response to an ascent and a descent of a lift for construction is installed, comprises a rotation control means controlling the rotational angle of the rotating angle in accordance with an approach of the lift. The rotation control means includes: a base installed on the safety door frame; a leg provided to be interposed between the safety door frame and the base; a servo motor installed on the base; and a stopper axially installed to be rotated by the servo motor to support the rotating angle to fix the rotating angle or rotate to be prevented from interfering with the rotating angle in accordance with the operation of the servo motor. The present invention has numerous effects such as convenient installation and high operating reliability.

    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 안전문틀의 일측에서 안전문의 개폐에 따라 회동되도록 설치된 회동앵글을 갖는 안전문 자동 잠금장치에 있어서, 리프트의 접근에 따라 회동앵글의 회동각도를 제어하는 회동제어수단가 포함되며, 회동제어수단은, 안전문틀에 설치되는 베이스와, 안전문틀과 베이스 사이에 개재되도록 구성되는 레그와, 베이스에 설치되는 서보모터와, 서보모터에 의해 회동되도록 축설되어, 회동앵글이 고정되게 지지하거나 또는 서보모터의 작동에 따라 회동앵글에 간섭되지 않게 회동하도록 구성된 스토퍼가 포함된 것을 특징으로 하며, 이러한 본 발명에 의해 설치가 간편하면서도 작동 신뢰도가 높은 등 다수의 효과를 기대할 수 있는 발명이다.
