地铁新型单扇防护密闭门的研制

Research of New Single Leaf Protective Airtight Door Metro

为满足地铁安全疏散口人员通行方便的需要,实现战时快速转换,研制出地铁新型单扇防护密闭门。新型单扇防护密闭门采用无门槛形式,大大地缩短了平战转换时间。采用蜗轮蜗杆减速器带动凸轮机构形式的底部密封装置,能很好地实现门框底部的防护密闭,具有结构紧凑、防护性能安全可靠的优点。

In order to meet the ease of access of subway safety evacuation exit, and realize rapid transitions in wartime, the new single leaf protective airtight door of metro is developed. To avoid setting a fixed threshold or live threshold at entrance,the new single leaf protective airtight door without threshold greatly shortens the transition time between peacetime and wartime. Using the worm reducer to drive the cam mechanism,the bottom sealing device can realize airtight at the bottom of the doorframe,and it has the advantages of compact structure,safety and reliable performance.
