The invention belongs to the field of elevator equipment, and particularly relates to an extensible intelligent guardrail of an elevator car roof. The extensible intelligent guardrail comprises a combined guardrail, a driving assembly, a pressure sensor and a controller, wherein, the combined guardrail comprises a plurality of single guardrails; the single guardrails are connected with the side faces of the periphery of the car roof of an elevator in a turnover mode; the driving assembly is used for driving the single guardrails to be switched between the state parallel to the car roof plane and the state perpendicular to the car roof plane; the pressure sensor is used for detecting the pressure value of people standing on the car roof; and the controller is used for acquiring signals of the pressure sensor and switching the state of the combined guardrail according to the change of pressure value. The extensible intelligent guardrail further comprises an alarm device and an automatic guardrail limiting lock or an automatic guardrail limiting rod used for locking the state of the combined guardrail. According to the extensible intelligent guardrail, the problem that in the prior art, due to the space limitation of an old building, a conventional car roof guardrail cannot be installed and used in the elevator installed additionally is solved.
本发明属于电梯设备领域,具体涉及一种电梯轿顶的可伸展智能护栏。该可伸展智能护栏包括组合护栏、驱动组件,压力传感器以及控制器。其中,组合护栏包括多个单体护栏;各个单体护栏与电梯的轿顶的四周侧面可翻转连接。驱动组件用于驱动各个单体护栏在平行于轿顶平面的状态和垂直于轿顶平面的状态间切换。压力传感器用于检测轿顶上站人的压力值。控制器用于获取压力传感器的信号,并根据压力值的变换切换组合护栏的状态。本发明的可伸展智能护栏中还包括报警装置,以及用于对组合护栏的状态进行锁定的护栏自动限位锁或护栏自动限位杆。本发明解决了因现有技术中老旧建筑的空间局限性导致常规轿顶护栏在加装电梯中无法实现安装使用的问题。
