The invention relates to the technical field of elevator safety, and discloses a safe anti-falling safety protection device for a vertical lifting elevator. The device comprises an elevator shaft, an elevator is movably connected into the elevator shaft, connecting blocks are fixedly connected to the left end and the right end of the elevator, and rotating plates are movably connected to the sides, away from the elevator, of the connecting blocks. A speed limiting block is fixedly mounted on the side, close to the rotating plates, of the inner wall of the elevator shaft, a moving rod is fixedly connected to the top of the connecting block, a compression spring is fixedly connected to the top of the moving rod, and a movable rod is movably connected to the bottom of the compression spring. A friction block is driven to move along with movement of a pressure rod, so that the friction block moves in the direction away from the pressure rod and makes contact with the interior of the elevator shaft, friction force is generated, the sliding speed of the elevator is reduced, and the effects that when the elevator breaks down, speed reduction is automatically conducted in the elevator, and danger is prevented are achieved.

    本发明涉及电梯安全技术领域,且公开了一种垂直升降电梯安全防坠落安全保护装置,包括电梯井,所述电梯井内部活动连接有电梯,所述电梯左右两端固定连接有连接块,所述连接块远离电梯的一侧活动连接有转动板,所述电梯井内壁且靠近转动板的一侧固定安装有限速块,所述连接块顶部固定连接有移动杆,所述移动杆顶部固定连接有压缩弹簧,所述压缩弹簧底部活动连接有活动杆。通过随着压力杆的移动,从而带动摩擦块一起移动,使得摩擦块向远离压力杆的方向移动,从而与电梯井内部相接触,进而产生摩擦力,从而减小电梯下滑的速度,从而达到当电梯发生故障时,内部自动进行减速,防止发生危险的效果。
