The invention discloses an out-of-control stall protection device for an elevator, and belongs to the technical field of elevator protection. The device comprises a fixed bottom plate; the buffering mechanism comprises a supporting assembly and a compression spring, the supporting assembly is arranged on the fixed bottom plate, and the two ends of the compression spring are connected with the upper side and the lower side of the supporting assembly; the main buffer is vertically arranged at the top of the supporting assembly; the release mechanism is arranged on the fixed bottom plate, and the locking end of the release mechanism is buckled with the buffer mechanism and enables the compression spring to be in a compressed state; and the control unit is arranged on the supporting assembly, the control unit and the releasing mechanism and used for controlling the locking end of the releasing mechanism to be separated from the buffering mechanism. The buffer device can be installed at the bottom of an elevator shaft, when a control system receives an elevator overspeed signal, the electromagnet action controller controls the hook claw device to be released, at the moment, the buffer pops up instantaneously under the action of the compression spring, and therefore the buffer effect on an elevator car falling at a high speed or rising at a stall is achieved.

    本发明公开了一种电梯失控失速保护装置,属于电梯保护技术领域。其包括:固定底板;缓冲机构,其包括支撑组件以及压缩弹簧,支撑组件设置在固定底板上,压缩弹簧的两端与支撑组件的上下两侧连接;主缓冲器,其竖直设置在支撑组件的顶部;释放机构,其设置在固定底板上,释放机构的锁定端与缓冲机构相扣接并使得压缩弹簧处于压缩状态;控制单元,其设置于支撑组件,控制单元与释放机构并用于控制释放机构的锁定端脱离缓冲机构。本缓冲装置可安装在梯井底部,当控制系统接收到电梯超速信号时,电磁铁动作控制器控制勾爪装置释放,此时缓冲器在压缩弹簧的作用下瞬时弹出,以对高速坠落或失速上升的电梯轿厢起到缓冲作用。
