The invention discloses a front edge plate anti-lifting device for an escalator. According to the technical scheme of the front edge plate anti-lifting device for the escalator, the front edge plate anti-lifting device is characterized by comprising a protection switch, wherein the protection switch is fixed to a switch support, a striking rod is arranged on one side of the protection switch, thestriking rod is connected to a striking rod support, a switch support and the striking rod support are both fixed to a truss, the striking rod is connected with a comb plate through a hinge pin, the comb plate is arranged in a sliding rail, the sliding rail is arranged on a supporting plate, the supporting plate is fixed to the truss, the striking rod support and the striking rod form a lever structure through a bolt and a sleeve, and when foreign matter is clamped into the comb plate, the comb plate moves upwards abnormally, the vertical action protection switch is triggered through the leverstructure, and the escalator stops operating. The front edge plate anti-lifting device for the escalator has the technical effects that the safety performance of the escalator is improved through thestructure, the space is reasonably utilized, and a vertical action protection device is easier to trigger.

    本发明公开了一种自动扶梯前沿板防抬起装置,其技术方案要点为包括保护开关,所述保护开关固定在开关支架上,所述保护开关的一侧设置有打杆,所述打杆连接在打杆支架上,所述开关支架和打杆支架都固定在桁架上,所述打杆通过销轴与梳齿板连接,梳齿板安装于滑轨中,滑轨安装在支撑板上,所述支撑板固定在桁架上,所述打杆支架通过螺栓和套筒与打杆形成杠杆结构,当梳齿板卡入异物时梳齿板向上发生异动,通过杠杆结构触发垂直动作保护开关,扶梯停止运行。本发明的技术效果为该结构提高了扶梯的安全性能,而且合理利用空间,垂直动作保护装置更容易触发。
