The invention relates to the field of elevator accessories, and discloses an elevator falling holding casting which comprises a hoistway guide rail and a lift car slidably mounted in the hoistway guide rail, a traction wheel and a guide shoe roller attached to the hoistway guide rail are mounted at the top end of the lift car, and multiple sets of locking insertion holes are formed in the inner walls of the two sides, close to each other, of the hoistway guide rail. A locking holding stop cross rod set is arranged between the inner walls, corresponding to the locking stop insertion holes in the two sides of the well guide rail, of the bottom of the lift car, a centrifugal locking stop mechanism is arranged on the side face, corresponding to the locking holding stop cross rod set, of the bottom of the lift car, and a Y-shaped connecting assembly is connected between the locking holding stop cross rod set and the centrifugal locking stop mechanism. A speed transmission linkage mechanism connected with the shaft guide rail is further arranged at the bottom of the lift car, the elevator falling holding casting is in insertion fit with the locking insertion hole through the locking holding transverse rod set when an elevator falls in an accelerated mode due to faults, and a barrier is formed to prevent the lift car from continuing to fall. And irreparable safety accidents caused by rapid falling of the elevator are avoided.
本发明涉及电梯配件领域,且公开了一种电梯下落抱紧铸件,包括井道导轨和滑动安装在井道导轨中的轿厢,轿厢顶端安装有曳引轮以及与井道导轨贴合的导靴滚轮,井道导轨相互靠近的两侧内壁开设有多组锁停插孔,轿厢底部对应井道导轨两侧开设有锁停插孔的内壁之间设置有锁止抱停横杆组,轿厢的底部对应锁止抱停横杆组的侧面设置有离心锁停机构,锁止抱停横杆组和离心锁停机构之间连接有Y型连接组件,轿厢的底部还设置有与井道导轨连接有的传速联动机构,该电梯下落抱紧铸件通过锁止抱停横杆组与锁停插孔在电梯因故障加速下落时进行插进配合,形成了一道阻碍来阻止轿厢继续下落,避免电梯急速下落而造成不可弥补的安全事故。
