The invention relates to the technical field of elevator protection, and discloses an elevator anti-stall falling safety device which comprises a connecting shaft, fixing frames are fixedly installed at the left end and the right end of the connecting shaft correspondingly, speed limiting mechanisms are fixedly installed in the fixing frames, and a screw rod is rotationally connected into the connecting shaft; limiting mechanisms are movably hinged to the upper ends of the opposite faces of the fixing frames. According to the anti-stall falling safety device for the elevator, under the condition that a connecting shaft is in stall, a fixing frame rotates together and then drives a rotating rod to rotate, the rotating rod can be matched with a connecting spring to throw out a throwing rod towards the two sides in the rotating process, and under the action of the throwing rod, a pushing rod can be driven to move towards the two sides in an inclined rod; and then the inserting rods are driven to get close to each other under the action of the connecting rods, the reset springs are stretched, and when the inserting rods make contact with the speed limiting grooves, the speed of the speed limiting rods can be controlled under the action of friction force, so that the effect of controlling the speed is achieved.

    本发明涉及电梯保护技术领域,且公开了一种电梯用防失速下坠安全装置,包括连接轴,所述连接轴的左右两端均固定安装有固定框,所述固定框的内部固定安装有限速机构,所述连接轴的内部转动连接有螺杆,所述固定框相对面的上端活动铰接有限位机构。该电梯用防失速下坠安全装置,通过在连接轴在失速情况下,固定框会一起转动,然后带动转动杆转动,转动杆在转动过程中可以配合连接弹簧将甩杆向两侧甩出,在甩杆的作用下可以带动推动杆在斜杆的内部向两侧运动,再配合连接杆的作用带动插接杆相互靠近,对复位弹簧进行拉伸,待插接杆与限速槽接触时,因为在摩擦力的作用下可以对限速杆进行速度控制,从而实现了控制速度的效果。
