The invention discloses an elevator damping and buffering device, and belongs to the field of elevator damping devices. The elevator damping and buffering device comprises an elevator shaft body, an elevator body is arranged in the elevator shaft body, a pair of vertical guide rails are fixedly connected to the inner wall of the elevator shaft body, and the elevator body is connected between the pair of vertical guide rails in a sliding mode. The elevator damping and buffering device is characterized in that a plurality of evenly-distributed infrared speed measuring sensors are installed on the vertical guide rails, a buffering belt is connected between every two adjacent infrared speed measuring sensors, an electric extending plate is connected in each buffering belt in a sliding mode, a buffering base is fixedly connected to the bottom end of the elevator body, and a plurality of connecting columns are connected between the buffering base and the elevator body. According to the scheme, when an elevator falls, piezoelectric ceramic on the buffering base is impacted to trigger an air bag to be inflated to be disconnected with the connecting columns, the multiple buffering belts lock the elevator many times, damping and speed reducing are effectively carried out on the elevator, and the safety of personnel in the elevator is guaranteed.
本发明公开了一种电梯减震缓冲装置,属于电梯减震装置领域,一种电梯减震缓冲装置,包括电梯井主体,电梯井主体内设有电梯主体,电梯井主体的内壁上固定连接有一对垂直导轨,电梯主体滑动连接在一对垂直导轨之间,其特征在于:垂直导轨上安装有多个均匀分布的红外测速传感器,相邻两个红外测速传感器之间连接有缓冲带,缓冲内滑动连接有电致延伸板,电梯主体的底端固定连接有缓冲座,缓冲座与电梯主体之间连接有多个连接柱,本方案可以实现在电梯下坠时,通过缓冲座上的压电陶瓷受冲击后触发气囊充气与连接柱断开,且多个缓冲带对电梯进行多次抱死,有效对电梯进行减震和减速,保证电梯内人员安全。
