The invention discloses an elevator falling brake device, and relates to the technical field of elevator auxiliary equipment. The elevator falling brake device comprises an elevator car and rails, the rails are symmetrically mounted on the left and right sides of the elevator car and fixedly connected with the side wall of an elevator shaft, rail wheels are symmetrically arranged on the left and right sides of the elevator car up and down, and the rail wheels are in rolling connection with the rails; the rail wheels on the upper side and the lower side are connected with supporting plates, the rail wheels are rotationally connected with the supporting plates, a braking rack plate and a braking gear disc are clamped and fixed so as to prevent the elevator car from continuing to move downwards, and the braking effect is achieved, and an acceleration sensor drives a screw rod to rotate through a driving motor; and nuts drive the supporting plates on the left side and the right side to move inwards at the same time through push rods, the supporting plates drive the braking gear disc to move towards the braking rack plate through the supporting rods, the clamping degree of the braking gear disc towards the braking rack plate is increased, slipping is avoided, the braking effect of an elevator is effectively improved, and the stability is higher.

    本发明公开了一种电梯坠落刹车装置,涉及电梯辅助设备技术领域,包括电梯轿厢以及轨道,所述轨道对称安装在电梯轿厢左右两侧并与电梯井侧壁固定连接,所述电梯轿厢左右两侧上下对称设置轨道轮,所述轨道轮与轨道滚动连接,上下两侧所述轨道轮连接支撑板,所述轨道轮与支撑板转动连接,制动齿条板与制动齿轮盘卡接固定从而阻止电梯轿厢继续向下运动,实现制动刹车效果,所述加速度传感器通过驱动电机带动螺杆转动,所述螺母通过推杆带动左右两侧支撑板同时向内侧移动,所述支撑板通过支撑杆带动制动齿轮盘向制动齿条板处移动,增大制动齿轮盘向制动齿条板的卡紧度,避免出现打滑,有效提高了电梯的制动刹车效果,稳定性更高。
