The invention provides a multi-car intelligent parallel elevator car roof safety protection method, an elevator comprises cars, rails, a driving system and a control system, the driving system drives the cars to run along the rails, the rails in different hoistways are connected through switching rails, and the cars run among the different rails in a switching mode through the switching rails. When the lift car passes through the switching track, the driving system rotates relative to the lift car, the elevator further comprises a guardrail for limiting the position of a maintainer, the guardrail can stretch out and draw back or move in the direction perpendicular to the track, and when the control system detects that the guardrail is located at the position interfering with rotation of the driving system, the driving system drives the maintainer to move. And the control system controls the lift car not to pass through the switching track. According to the method, for the elevator car which needs to be switched to operate on different rails and is free of traction steel wire ropes, the personnel safety and the equipment safety can be guaranteed when maintainers conduct maintenance on the car roof, maintenance is comprehensive, and meanwhile it is guaranteed that a guardrail cannot interfere with operation of the car and cannot damage the structure of an elevator.

    本发明提供了多轿厢智能并行电梯轿顶安全防护方法,所述电梯包括轿厢、轨道、驱动系统和控制系统,驱动系统带动轿厢沿着轨道运行,不同井道内的轨道通过切换轨道连接,轿厢通过切换轨道在不同轨道之间切换运行,当轿厢经过所述切换轨道时,驱动系统相对轿厢转动,所述电梯还包括限定检修人员位置的护栏,护栏可在垂直于轨道的方向上伸缩或移动,当控制系统检测到护栏位于干涉驱动系统转动的位置时,控制系统控制轿厢不能经过所述切换轨道。本发明对于需要在不同轨道进行切换运行的、无曳引钢丝绳的电梯轿厢,通过所述方法可以保障检修人员在轿顶进行检修时的人员安全和设备安全,检修全面,同时确保护栏不会干涉轿厢的运行和损伤电梯的结构。
