The elevator roof rushing prevention structure comprises a derrick and a lift car frame, two sets of guide rails which are symmetrically arranged and slidably connected with the lift car frame are installed on the inner wall of the derrick, and roof rushing prevention parts are fixedly installed on the two side faces of the derrick correspondingly. An electric control module, a buffering mechanism, a laser distance measuring probe and a speed measuring sensor are installed on the top face of the derrick, the laser distance measuring probe and the speed measuring sensor are arranged right opposite to the lift car frame, and the anti-impact top component comprises a counterweight frame, two winding rollers which are symmetrically arranged and rotationally connected with the derrick and a pressure buffering bag which is fixed to the surface of the derrick and arranged opposite to the lift car frame. The surface of the pressure buffering bag communicates with an air connecting pipe, an air pressure probe a is installed in the pressure buffering bag, and an arresting cable is wound between the opposite surfaces of the two winding rollers. Through the arrangement of the dynamic counterweight assembly, the buffer mechanism, the laser distance measuring probe and the speed measuring sensor, the device can intelligently adjust the counterweight weight of the counterweight housing and the protection strength of the capsule column according to the top rushing speed of the lift car.

    本发明公开了一种电梯防冲顶结构及防冲顶方法,分别包括井架和轿厢架,井架的内壁安装有两组对称设置且与轿厢架滑动连接的导轨,井架的两侧面均固定安装有防冲顶部件,井架的顶面分别安装有电控模组、缓冲机构和正对轿厢架设置的激光测距探头和测速传感器,防冲顶部件分别包括对重架、两个对称设置且与井架转动连接的卷辊和固定于井架表面且相对轿厢架设置的缓压囊,缓压囊的表面连通有联气管,缓压囊的内部安装有气压探头a,两个卷辊的相对表面之间卷绕有拦阻索。本发明通过动态配重组件、缓冲机构、激光测距探头和测速传感器的设置,使得本装置能够依据轿厢的冲顶速度智能调节对重架的配重重量及囊柱的防护强度。
