The automatic locking type elevator speed limiter comprises a shell and a speed limiting assembly, the other end of a brake sleeve extends into a brake drum, one end of a pull plate is connected with a pressing block, the other end of the pull plate is connected with a pin shaft, the end, extending out of the shell, of the pin shaft is provided with a rolling bearing, and a limiting plate is arranged outside the shell; the limiting plate is rotatably connected to the shell through a limiting shaft, a tension spring is connected to the limiting plate, when the pin shaft is located at the end, close to the limiting shaft, of the kidney-shaped hole, the rolling bearing abuts against the upper end of the abutting part, and when the pin shaft is located at the end, away from the limiting shaft, of the kidney-shaped hole, the rolling bearing abuts against the upper end of the flat plate part and the side wall of the abutting part; when the speed limiter is in a mechanical action state, the limiting plate abuts against the rolling bearing at the moment, so that the pin shaft is difficult to reset, the pin shaft does not reset, the pulling plate cannot reset, the pressing block still presses the steel wire rope, the steel wire rope still triggers the action of the safety tongs, counter-weight action is avoided, the car is driven to ascend and descend repeatedly, and the safety of passengers in the car is effectively guaranteed.

    本发明涉及自动锁止型电梯限速器,包括壳体和限速组件,制动套的另一端延伸至制动鼓内,拉板的一端连接有压块,另一端连接有销轴,销轴延伸至壳体外的一端设置有滚动轴承,壳体外设置有限位板,限位板通过限位轴可转动的连接在壳体上,限位板上连接有拉簧,销轴位于腰型孔靠近限位轴的一端时,滚动轴承与抵触部的上端相抵触,销轴位于腰型孔远离限位轴的一端时,滚动轴承与平板部上端和抵触部侧壁相抵触;在限速器处于机械动作状态时,限位板此时紧抵滚动轴承,使得销轴难以复位,销轴不复位,拉板就不能复位,压块仍然压在钢丝绳上,钢丝绳依然触发安全钳的动作,避免对重动作,带动轿厢的重复上升、下降,有效保证了轿厢内乘客的安全。
