The invention provides a comb plate protection device and an escalator. The comb plate protection device comprises a first connecting rod, a second connecting rod, a shifting fork, a roller and an electric switch. The shifting fork comprises a shifting fork head and two shifting fork feet. The shifting fork feet form a notch. The shifting fork head is located outside the notch. One end of the first connecting rod is connected with the side, away from a comb plate, of a comb tooth supporting plate, and the other end of the first connecting rod is connected with the shifting fork head. The roller is located in the notch formed by the shifting fork feet and is fixedly connected to one end of the second connecting rod. The other end of the second connecting rod is connected with the electricalswitch, and the electrical switch is connected with an electric circuit of the escalator and used for controlling the on-off state of the electrical circuit of the escalator. The shifting fork, the roller, the second connecting rod and the electric switch are mounted in parallel in a first direction, and the first direction is the direction of a connecting line between the comb plate and the combtooth supporting plate. The device can protect the comb plate in multiple directions, and the security of the escalator is improved.

    本发明提供了一种梳齿板保护装置及自动扶梯,梳齿板保护装置包括第一连杆、第二连杆、拨叉、滚轮和电气开关,拨叉包括一拨叉头和两个拨叉脚,拨叉脚构成一槽口,拨叉头位于槽口的外部,第一连杆的一端连接梳齿支撑板远离梳齿板的一边,另一端连接拨叉头;滚轮位于拨叉脚构成的槽口内,并与第二连杆的一端固定连接;第二连杆的另一端连接电气开关,电气开关与自动扶梯的电气回路连接,用于控制自动扶梯电气回路的开启和闭合;其中,拨叉、滚轮、第二连杆和电气开关沿第一方向平行安装,第一方向为梳齿板到梳齿支撑板之间的连线方向。该装置可以在多个方向上保护梳齿板,增加了自动扶梯的安全性。
