The invention discloses a bent guide rail safety device. The device comprises first guide rails, second guide rails and pressing rails. The upper end of a first swing arm is rotatably connected with the front side of one pressing rail, and the lower end of the first swing arm is rotatably connected with a truss. A first torsion bar spring comprises a first hook section hung on the first swing arm and a first torsion bar section connected with the first hook section. The upper end of a second swing arm is rotatably connected with the rear side of one pressing rail, and the lower end of the second swing arm is rotatably connected with the truss. A second torsion bar spring comprises a second hook section hung on the second swing arm and a second torsion bar section connected with the second hook section. A near-end limiting block is arranged below one pressing rail. The device has a bent section step safety monitoring function, when auxiliary wheels of the step are abnormally lifted at the bent section and exceed a threshold value, a monitor is triggered, a signal is sent to a control system, an escalator is stopped, and safety is ensured.

    本发明公开了一种弯曲导轨安全装置,包括:第一导轨、第二导轨、压轨;第一摆臂的上端与压轨的前侧可转动地连接,第一摆臂的下端与桁架可转动地连接;第一扭杆弹簧包括:挂设于第一摆臂上的第一挂钩段、与第一挂钩段相连接的第一扭杆段;第二摆臂的上端与压轨的后侧可转动地连接,第二摆臂的下端与桁架可转动地连接;第二扭杆弹簧包括:挂设于第二摆臂上的第二挂钩段、与第二挂钩段相连接的第二扭杆段;压轨的下方设有近端限位块。本发明具有弯曲段梯级安全监测功能,当梯级副轮在弯曲段异常抬起超过一阈值时,触发监测器,并将信号发送至控制系统,制停扶梯,确保安全。
