The invention belongs to the technical field of elevators, and particularly relates to a self-rescue system used during fault of an elevator. The self-rescue system used during fault of the elevator comprises an elevator car and a landing door. Escape windows are formed in a car door of the elevator car and the landing door correspondingly. A first plate is arranged in the escape window of the cardoor. A vertical side wall of the first plate is hinged to the upper side wall and the lower side wall of the escape window. A second plate is arranged in the escape window of the landing door. A vertical side wall of the second plate is hinged to the upper side wall and the lower side wall of the escape window. First torsional springs are arranged at the hinged position of the first plate and the side wall of the escape window and the hinged position of the second plate and the side wall of the escape window correspondingly. Through cooperation of the escape windows, the first plate and thesecond plate, when the elevator has a power failure fault, the first plate is pulled open and the second plate is pushed open in the elevator car, and people escape from the elevator car from the escape windows. Meanwhile, the first plate and the second plate are hinged to the side walls of the escape windows through the first torsional springs correspondingly, thus, when the elevator operates andis used, the first plate and the second plate are always arranged in the escape windows, and the circumstance that the first plate and the second plate extend out of openings of the escape windows, and consequently up-down movement of the elevator is affected is avoided.
本发明属于电梯技术领域,具体的说是一种电梯故障自救系统,包括电梯轿厢和层门;电梯轿厢的轿门和层门上各开设逃生窗;轿门的逃生窗内设有一号板;一号板的一竖直侧壁铰接逃生窗的上下侧壁;层门的逃生窗内设有二号板;二号板的一竖直侧壁铰接逃生窗的上下侧壁;一号板和二号板与逃生窗侧壁铰接位置各设有一号扭簧;通过逃生窗、一号板和二号板之间的配合,使得电梯出现断电故障时,电梯轿厢内部拉开一号板和推开二号板,从逃生窗逃离电梯轿厢;同时一号板和二号板通过一号扭簧各自铰接逃生窗侧壁,使得电梯在运行使用时,一号板和二号板一直置于逃生窗内,避免一号板和二号板凸出逃生窗的窗口,影响电梯的上下移动。
