The invention relates to an intelligent safety system for an elevator car roof. The device comprises a fixed guardrail, a car roof maintenance box, a pressure sensor, a movable guardrail, two travel switches and a controller, the fixed guardrails are arranged on the other three sides, except the side close to the landing door, of the car roof. The car roof maintenance box is used for switching the running state of the elevator into a maintenance state or a normal state; the pressure sensor is arranged on the car roof of the elevator, and the pressure sensor is used for detecting whether a person stands on the car roof or not and generating a pressure signal; the movable guardrail is arranged on the side, close to the landing door, of the car roof and is of a sliding door structure. Through the arrangement of the movable guardrails, when the elevator runs out of an unlocking area, although the horizontal clear distance between the shaft wall on one side of the landing door and the lift car is possibly large, under the condition that the guardrails are arranged on the periphery of the lift car roof, the risk that relevant personnel on the lift car roof fall into the shaft does not exist; and the personal safety of operators, inspection and detection personnel and the like is greatly improved.
本发明涉及一种电梯轿顶智能安全系统。其包括固定护栏、轿顶检修盒、压力传感器、可移动护栏、两个行程开关和控制器;所述固定护栏设置在轿顶除靠近层门一侧的另外三侧;轿顶检修盒,其用于将电梯的运行状态切换为检修状态或正常状态;压力传感器,其设置在电梯的轿顶,所述压力传感器用于检测轿顶是否有人员站立,并产生压力信号;可移动护栏,其设置在轿顶靠近层门的一侧,且为推拉门结构。本发明通过可移动护栏的设置,电梯运行至开锁区域以外时,尽管层门一侧的井道壁与轿厢之间的水平净距离可能会很大,但轿顶四周均设有护栏的情况下轿顶相关人员不会存在坠入井道的风险,大大提高作业人员、检验检测人员等的人身安全。
