The present invention relates to a device for automatically locking a safety door of a construction lift and, more specifically, to a locking means of an opening and closing device applied to a floor safety door of a building corresponding to a construction lift. In regard to a device for automatically locking a safety door having a safety door frame in which a floor safety door of a building opened and closed in response to the lifting of a construction lift is installed, and a rotary angle installed to be rotated in accordance with the opening and closing of the safety door on one side of the floor safety door, the device includes: an angle fixing means combined with the rotary angle; and a rotation control means formed in the safety door frame to control the rotation angle of the angle fixing means in accordance with the approach of the lift. The rotation control means includes: a body combined with the safety door frame; a servo motor installed in the body; and a stopper combined to be rotated by the servo motor to support the angle fixing means installed to be opposed thereto such that the angle fixing means is fixed, or formed to be rotated without causing interference in the angle fixing means in accordance with the operation of the servo motor. According to the present invention, multiple effects such as convenient installation, high operation reliability and the like 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 안전문틀과, 안전문틀의 일측에서 안전문의 개폐에 따라 회동되도록 설치된 회동앵글을 갖는 안전문 자동 잠금장치에 있어서, 회동앵글에 결합되는 앵글고정수단과, 안전문틀에 구성되어 리프트의 접근에 따라 앵글고정수단의 회동각도를 제어하는 회동제어수단을 포함하며, 회동제어수단은, 안전문틀에 결합되는 본체와, 본체에 설치되는 서보모터와, 서보모터에 의해 회동되도록 결합되어 마주보도록 설치된 앵글고정수단을 고정되게 지지하거나 또는 서보모터의 작동에 따라 앵글고정수단에 간섭되지 않도록 회동되게 구성된 스토퍼가 포함된 것을 특징으로 하며, 이러한 본 발명에 의해 설치가 간편하면서도 작동 신뢰도가 높은 등 다수의 효과를 기대할 수 있는 발명이다.
