The invention belongs to the technical field of elevators, and particularly relates to an elevator and a door vane device thereof. Wherein the door knife device comprises an anti-pinch assembly, the anti-pinch assembly comprises a detection sensor and a trigger part, at least one of the detection sensor and the trigger part is in linkage with the door knife mechanism, and when the resistance borne by the door knife mechanism when the door knife mechanism clamps the landing door ball to move exceeds a preset value, the trigger part triggers the detection sensor. When foreign matters are clamped into the gap between the car door and the landing door and the gap between the landing door and the door pocket, the detection sensor is triggered, and the elevator door opening action is stopped, so that the anti-pinch assembly is integrally arranged on the door knife device, the situation that the foreign matters are clamped into the gaps to affect normal door opening of the elevator can be avoided, and the clamped objects are prevented from being damaged; reliable guarantee is provided for safe operation of the elevator; moreover, triggering of the detection sensor is achieved through linkage with the door knife mechanism, other driving structures do not need to be additionally arranged, and the door knife device is simple in overall structure, convenient to overhaul and maintain and high in use value.

    本发明属于电梯技术领域,更具体地说,是涉及一种电梯及其门刀装置。其中,门刀装置包括防夹组件,防夹组件包括检测传感器和触发件,检测传感器和触发件的至少之一与门刀机构联动,当门刀机构夹持层门球移动时所受的阻力超过预设值时,触发件触发检测传感器。当轿门与层门之间的间隙、层门与门套之间的间隙卡入异物时,检测传感器被触发,电梯开门动作停止,这样,于门刀装置集成设置防夹组件,能够避免因异物夹入间隙而影响电梯正常开门,避免对夹入物体造成损伤,为电梯的安全运行提供了可靠的保障;并且,检测传感器的触发通过与门刀机构联动实现,无需增设其他的驱动结构,门刀装置整体结构简单,检修维护方便,具有较高的使用价值。
