The present invention relates to a cradle lifting wire safety device. More specifically, the cradle lifting wire safety device includes: a frame; a cradle which is placed in a lower part of the frame, and on which an article is mounted; a folding link connecting the frame with the cradle; a lifting means provided in the frame, and including a plurality of wires connected with the cradle to maintain horizontality of the cradle while lifting and lowering the cradle; and a safety means subordinated to the tension of the wires of the lifting means while stopping the lifting operation of the cradle by sensing a situation in which any one of the wires is released from the tension or loosened. In other words, in accordance with the present invention, the cradle lifting wire safety device can maintain the horizontality of a cradle for installing articles such as a beam projector, an air purifier, an air blower and the like on a ceiling of a building, and can provide a safety means for sensing a situation in which a wire for lifting up and down the cradle is tangled or unwound, and, in particular, the safety means stops the lifting operation of the cradle, on which an article is mounted, by sensing a situation in which the tension of the wire in a normal state is released or loosened, thereby preventing accidents, and increasing the reliability of the device through a quick post-treatment.

    본 발명은 거치대 승하강 와이어 안전장치에 관한 것으로, 더욱 상세하게는 프레임; 상기 프레임 하부에 배치되고, 물품이 장착되는 거치대; 상기 프레임과 상기 거치대를 연결하는 절첩링크; 상기 프레임에 구비되고, 상기 거치대에 연결되어 상기 거치대의 수평 유지 및 승하강을 위한 복수의 와이어를 포함하는 승하강수단; 및 상기 승하강수단의 와이어 장력에 종속되되, 상기 와이어 중 어느 하나의 와이어라도 장력이 해제되거나, 이완되는 경우 이를 감지하여 상기 거치대의 승하강 동작을 정지시키는 안전수단;을 포함하여 이루어진다. 즉 본 발명은 빔 프로젝터, 공기청정기 및 송풍기 등의 물품을 건물 천정에 설치하기 위한 거치대의 수평을 유지하고, 거치대를 승하강시키기 위한 와이어가 꼬이거나, 풀리는 경우 이를 감지하기 위한 안전수단을 도입하며, 특히 안전수단은 정상상태에서의 와이어 장력이 해제되거나, 이완되는 경우 이를 감지하여 물품이 장착된 거치대의 승하강 동작을 정지시킴으로써 안전사고를 미연에 방지하고, 신속한 사후조치를 통해 장치의 신뢰성을 높일 수 있는 거치대 승하강 와이어 안전장치를 제안하고자 한다.
