A buffer protection device relates to the technical field of mechanical buffer equipment. The buffer protection device comprises a supporting plate, a buffer energy absorption mechanism and a pressed block arranged above the supporting plate, the buffer energy absorption mechanism comprises a fixing plate fixed to the supporting plate, and a trapezoidal sliding groove is formed in the fixing plate; a cutting sliding block which can move from the end with the larger groove width to the end with the smaller groove width and extrude and cut the side wall of the trapezoidal sliding groove is arranged in the trapezoidal sliding groove, and the pressed block is connected with the cutting sliding block through a connecting rod mechanism. The buffer protection device is compact in structure, force in the vertical direction is mainly converted into force in the transverse direction, so that the whole device is thinner and smaller in size, the overall mass can be lighter, the buffer protection device can be directly installed at the bottom of an elevator and does not need to be installed in an elevator pit, and the safety of the elevator is improved. And the situations of equipment corrosion, faults and the like caused by water accumulation in the pit of the elevator can be avoided, and meanwhile a good buffering effect can be achieved when the elevator falls.

    一种缓冲防护装置,涉及机械缓冲设备技术领域。前述缓冲防护装置包括支撑板、缓冲吸能机构和设在支撑板上方的受压块,缓冲吸能机构包括固定在支撑板上的固定板,固定板上设有梯形滑动槽,梯形滑动槽中设有能够从槽宽较大一端向槽宽较小一端移动并挤压和切削梯形滑动槽侧壁的切削滑块,受压块通过连杆机构与切削滑块相连。上述缓冲防护装置结构紧凑,主要通过将竖直方向的力转变成横向方向的力,从而使得整个装置做得更薄,体积更小,整体质量也可做得更轻,让该缓冲防护装置能够直接安装在电梯底部,无需再安装在电梯底坑当中,可避免因电梯底坑积水而出现的设备锈蚀和故障等情况,同时还能在电梯下坠时起到较好的缓冲作用。
