The invention relates to the technical field of escalators, and discloses an anti-toppling escalator pedal. The anti-toppling escalator pedal comprises a pedal body, the side face of the pedal body is engaged with a conveying chain, air bags are fixedly connected to the bottom of the pedal body, reset springs are fixedly connected to the interiors of the air bags, trigger rods are movably connected to the interiors of the reset springs, a bottom plate is connected to the outer side of the trigger rods in a sliding mode, air outlet holes are formed in the two sides of the interior of the bottom plate, and travel switches are fixedly connected to the bottoms of the air outlet holes. Button of travel switches are pressed through the trigger rods, so that magnetic poles at the two ends of a coil rod are changed, one end, close to a conical block, of the coil rod is a different-name magnetic pole, the conical block is attracted to be separated from a conical hole, air of an air pump rapidly enters the interiors of the air bags, therefore an anti-toppling device can be automatically triggered, a pedal is kept balanced, and people are prevented from losing balance or being rolled into the interior of the elevator.
本发明涉及扶手电梯技术领域,且公开了一种防止倾倒的扶手电梯踏板,包括踏板,所述踏板的侧面啮合有传送链条,所述踏板的底部固定连接有气囊,所述气囊的内部固定连接有复位弹簧,所述复位弹簧的内部活动连接有触发杆,所述触发杆的外侧滑动连接有底板,所述底板内部的两侧开设有出气孔,所述出气孔的底部固定连接有行程开关。通过触发杆按压行程开关的按钮,使得线圈杆两端的磁极发生改变,线圈杆与锥形块相近的一端为异名磁极,所以锥形块被吸引使得锥形块与锥形孔分离,气泵的气体快速进入气囊的内部,从而达到了能够自动触发防倾倒装置,使踏板保持平衡,防止人员失去平衡或者卷入电梯内部的效果。
