The invention relates to the technical field of rail transit, in particular to a safety shielding door for rail transit, two sides of a shielding door frame body are respectively and fixedly provided with fixed doors, two movable doors are arranged between the two fixed doors, a sliding rail is fixedly arranged on the shielding door frame body above the movable doors, and the sliding rail is parallel to the length direction of the movable doors. Two sliding blocks are installed in the sliding rail in a sliding mode and fixedly connected to the corresponding movable doors respectively, a first rack parallel to the length direction of each movable door is fixedly installed at the top end of the movable door, and a servo motor corresponding to each first rack is fixedly installed on the portion, on one side of the corresponding first rack, of the shielding door frame body. The tail ends of output shafts of the servo motors are fixedly and respectively provided with third gears meshed with the corresponding first racks, and movable pedal modules are arranged below the two movable doors. By arranging the movable pedal module linked with the shielding door, the step missing prevention effect can be achieved, and the train operation safety is greatly improved.
本发明涉及轨道交通技术领域,尤其是一种轨道交通用安全屏蔽门,屏蔽门框体两侧分别固定安装有一个固定门,两个固定门之间设置有两个活动门,活动门上方的屏蔽门框体上固定安装有一个滑轨,且滑轨平行于活动门长度方向设置,滑轨内可滑动安装有两个滑块,两个滑块分别固定连接在对应的活动门上,每个活动门顶端均固定安装有一个平行于其长度方向设置的第一齿条,每个第一齿条一侧屏蔽门框体上均固定安装有一个与之对应的伺服电机,伺服电机的输出轴末端上均固定安装有一个与第一齿条啮合的第三齿轮,两个活动门下方设置有活动踏板模块。本发明通过设置与屏蔽门联动的活动踏板模块,可以实现防踩空效果,大大提高列车运行安全性。
