The invention discloses an emergency anti-falling system for a building construction elevator and a method. The emergency anti-falling system comprises an elevator body located in an elevator protection shell, a base is fixedly connected to the lower end of the elevator body, a cylindrical cavity is formed in the base, a sliding plate is slidably connected to the inner wall of the cylindrical cavity, a vertical rod is fixedly connected to the lower end of the sliding plate, the upper end of the sliding plate is fixedly connected with an annular air bag, the annular air bag is filled with magnetorheological fluid, and a driving device for driving the sliding plate to move is installed on the base. According to the emergency anti-falling system for the building construction elevator and themethod, a wing-shaped plate, a transverse rod, the vertical rod, the sliding plate, the annular air bag and the magnetorheological fluid are arranged, when the elevator body falls, the wing-shaped plate drives the transverse rod to slide so that the sliding plate can carry out extrusion on the annular air bag, the magnetorheological fluid in the annular air bag can enter a groove, a sliding plug is pushed to enable a brake block to be matched with a brake groove, and the elevator body is forced to stop.

    本发明公开了一种建筑施工电梯用紧急防坠落系统及方法,包括位于电梯防护外壳内的电梯本体,所述电梯本体下端固定连接有底座,所述底座上开设有圆柱腔,所述圆柱腔内壁滑动连接有滑板,所述滑板下端固定连接有竖杆,所述滑板上端固定连接有环形气囊,所述环形气囊内填充有磁流变液,所述底座上安装有驱动滑板移动的驱动装置。本发明通过设置翼型板、横杆、竖杆、滑板、环形气囊以及磁流变液,在电梯本体坠落时,翼型板带动横杆滑动使得滑板对环形气囊进行挤压,使得环形气囊内的磁流变液进行凹槽内,推动滑塞使得制动块与制动槽配合,对电梯本体进行迫停。
