The invention discloses a safety braking device for an elevator. The safety braking device comprises a mounting plate, wherein damping springs and damping rubber strips which are distributed at equalintervals are welded to the outer wall of the top of the mounting plate, a lift car is welded to the outer walls of the tops of the damping springs and the damping rubber strips, supporting legs are welded to the periphery of the outer wall of the bottom of the lift car, mounting grooves are welded to the periphery of the outer wall of the top of the mounting plate, fixing holes are formed in thesupporting legs and the mounting grooves, fixing pins are arranged in the fixing holes, buffer springs are welded to the inner walls of the bottoms of the mounting grooves, the tops of the buffer springs are welded to the outer walls of the bottoms of the supporting legs, and hydraulic oil cylinders are welded to the outer walls of the two sides of the lift car and the outer walls of the two sidesof the mounting plate. According to the safety braking device, limiting blocks and guide blocks act synchronously, so that the lift car is basically kept to be horizontally clamped on guide rails, the lift car is prevented from inclining, the damping springs, the damping rubber strips and the buffer springs keep the lift car stable, passengers in the lift car are prevented from falling down, thelift car is prevented from inclining, a displacement sensor monitors the running speed of the lift car in real time, the braking speed is high, and the efficiency is high.

    本发明公开了一种电梯用安全制动装置,包括安装板,安装板顶部外壁焊接有等距离分布的减震弹簧与减震胶条,减震弹簧与减震胶条顶部外壁焊接有轿厢,轿厢底部外壁四周均焊接有支撑腿,安装板顶部外壁四周均焊接有安装槽,支撑腿与安装槽均开有固定孔,固定孔设置有固定销,安装槽底部内壁焊接有缓冲弹簧,缓冲弹簧顶部与支撑腿底部外壁焊接,轿厢两侧外壁与安装板两侧外壁均焊接有液压油缸。本发明中,限位块与导向块同步动作,使轿厢基本保持水平地夹持在导向轨道上,防止轿厢倾斜,减震弹簧、减震胶条与缓冲弹簧保持轿厢的稳定,防止轿厢内部乘客摔倒,避免轿厢倾斜,位移传感器实时监测轿厢运行速度,制动速度快,效率高。
