The invention provides an anti-falling type elevator, and relates to the field of elevators. The anti-falling type elevator comprises stand columns, a driving mechanism and a lifting frame, wherein locking structures are arranged on the stand columns, and an anti-falling mechanism is arranged on the lifting frame. The anti-falling mechanism comprises a transmission rod, an elastic piece and locking pieces, wherein the transmission rod is vertically and movably installed on the lifting frame, lifting chains or lifting belts are connected between one end of the transmission rod and the driving mechanism, a connecting rod structure is connected between the other end of the transmission rod and each locking piece, and the elastic piece is connected to the transmission rod. The anti-falling mechanism has a working state and a locked state; when the anti-falling mechanism is in the working state, the transmission rod overcomes the elastic acting force of the elastic piece and drives the locking pieces to be unlocked; and when the anti-falling mechanism is in the locked state, the elastic piece drives the transmission rod and drives the locking pieces to be locked with the locking structures in a matched mode. The connecting rod structure is adopted for force transmission between the transmission rod and each locking piece, the structure is simple, elastic potential energy of the elastic piece can be directly transmitted to the locking pieces, then the lifting frame can be locked rapidly and reliably, and therefore anti-falling safety is guaranteed.

    本发明提供了一种防坠式升降机,涉及升降机领域。防坠式升降机包括立柱、驱动机构和升降架,立柱上设置有锁止结构,升降架上设有防坠机构;防坠机构包括传动杆、弹性件和锁止件,传动杆竖向活动安装在升降架上,传动杆的一端和驱动机构之间连接有提升链条或提升皮带,传动杆的另一端与锁止件之间连接有连杆结构,弹性件连接在传动杆上;防坠机构具有工作状态和锁止状态,在工作状态时,传动杆克服弹性件的弹性作用力并带动锁止件解锁,在锁止状态时,弹性件驱动传动杆并带动锁止件与锁止结构锁止配合。传动杆和锁止件之间采用连杆结构传力,结构简单,可将弹性件的弹性势能直接传递至锁止件,实现快速可靠地锁止升降架,确保了防坠安全性。
