具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
在本发明的描述中，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明而不是要求本发明必须以特定的方位构造和操作，因此不能理解为对本发明的限制。本发明中使用的术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接；可以是直接相连，也可以通过中间部件间接相连。
如图1至图4所示，本发明提供了一种高速铁路隧道疏散通道活门槛防火防护密闭门，主要包括门框1、门扇2、铰页3、闭锁4、活门槛6和密封装置5。门框1安装在隧道墙体上，能够为门扇2、铰页3、活门槛6、密封装置5提供安装位置。门扇2通过铰页3实现与门框1的可转动配合，铰页3一端安装在门框1上，另一端安装在门扇2上。闭锁4安装在门框1上，并与门框1滑动配合，能够锁闭和解锁门扇2。活门槛6安装在门框1的底部，并与隧道墙体相连，在门扇2闭合时活门槛6与门扇2的底部相抵，能够支撑门扇2。密封装置5安装在门框1和门扇2上，在门扇2闭合时嵌压在活门槛6上，能够密封门扇2和门框1、门扇2和活门槛6之间的间隙，起到密封、防火的作用。
具体而言，本发明的高速铁路隧道疏散通道活门槛防火防护密闭门在安 装施工时无需在高速铁路隧道疏散通道的地面上设置台阶。在门扇2处于闭合状态时，本发明通过门框1与门扇2的配合、活门槛6与门扇2的配合来支撑门扇2，并通过在门框1与门槛之间安装密封装置5、密封装置5与活门槛6的配合实现密封和防火。在需要进行物资和人员的输送工作时，闭锁4由锁闭状态解锁，推动(或拉动)门扇2，门扇2绕铰页3旋转开启，在门扇2开启到最大角度时(与锁闭状态的夹角不小于90°时)，将活门槛6由安装位置拆除(活门槛6可拆卸)，拆除活门槛6后，高速铁路隧道疏散通道的地面为平面，便于物资和人员通过。本发明通过设置活门槛6来改善防护门的安装条件，在安装防护门时不必设置台阶，具有施工方便的特点；同时，本发明的活门槛6可拆除，便于物资和人员通过，还具有通过性能强的特点。
进一步的，如图1、图4、图5、图22至图25所示，活门槛6包括安装板610、骨架620和第一密封块630。安装板610安装在门框1上，能够为骨架620提供定位，并为骨架620提供安装空间。骨架620与安装板610相连(可以焊接在安装板610上)，骨架620上设有用于容纳第一密封块630的凹槽，能够为第一密封块630提供安装位置。第一密封块630安装在骨架620的凹槽内，第一密封块630的长度大于骨架620的长度，两端搭接在门框1上，在门扇2闭合时，密封装置5嵌压在第一密封块630上，从而能够密封门扇2与活门槛6之间的间隙。
进一步的，如图1、图4、图5、图22至图25所示，安装板610为角钢，通过多个螺栓固定在门框1上，多个螺栓在安装板610的长度方向均匀分布，在使用时能够为安装板610提供牢固的固定安装，在拆卸时便于拆卸。
进一步的，如图1、图4、图5、图22至图25所示，第一密封块630为闭孔海绵橡胶防火膨胀材料制成，Shore C硬度范围为30至40，密度为0.45至0.54g/cm 3，扯断伸长率不小于350％，扯断强度不小于7.5MPa，防火性能能够满足《防火膨胀密封件》GB16807的相关要求，防火密封性强。
进一步的，如图1、图4、图5、图22至图25所示，活门槛6还包括承压架650，在门扇2闭合时承压架650与门扇2相抵，从而能够在门扇2的底部支撑门扇2。承压架650包括承压板651和压板652。承压板651与骨架620相抵，骨架620的两侧(靠近门扇2的一侧和远离门扇2的一侧)分别 固定有安装板610(位于骨架620远离门扇2的一侧)和承压板651(位于骨架620靠近门扇2的一侧)，能够将骨架620在水平方向固定牢固(骨架620被承压板651和安装板610夹在中间，靠承压板651和安装板610的夹持实现固定)。承压板651的长度方向上设有台阶，台阶能够在门扇2闭合时与门扇2相抵，从而支撑门扇2。承压板651的长度方向的两端设有斜坡，压板652通过螺栓安装在门框1上，并在斜坡的顶部挤压斜坡，与斜坡相抵，能够对承压板651进行固定。
进一步的，如图1、图4、图5、图22至图25所示，承压架650还包括限位板653，限位板653焊接在门框1上，并在压板652的顶部与压板652相连，能够防止压板652上窜，从而能够限定压板652的位置，进而确保承压板651安装的牢固性。在拆卸活门槛6时，首先拧松压板652上的螺丝，抽出承压板651，然后移除骨架620，最后松开安装板610上的螺栓，移出安装板610。在安装活门槛6时，首先安装安装板610，然后将骨架620放置在安装板610的右侧，骨架620上安装第一密封块630和第二密封块640，最后将承压板651抵在骨架620的右侧，拧紧压板652上的螺栓，实现承压板651的固定，完成活门槛6的安装。
进一步的，如图1、图4、图5、图22至图25所示，骨架620垂直于长度方向的截面呈F型，第一密封块630位于F型的凹槽内，与密封装置5配合，能够密封门扇2与骨架620之间的缝隙。承压板651在F型的右侧与骨架620相抵，承压板651和骨架620之间还设有第二密封块640，第二密封块640位于骨架620与承压板651围成的空腔内，且位于第一密封块630的下方，能够密封承压板651与骨架620之间的缝隙。
进一步的，如图1、图4、图5、图22至图25所示，在骨架620的截面呈现的F型中，顶部的横板呈水平设置，位于顶部下方的第二道横板呈斜向上的倾斜设置，不仅便于第二密封块640的安装，还便于对第一密封块630的固定，此外，由于从左到右第一密封块630呈收口状，还便于增大第一密封块630的形变量，提高密封效果。
进一步的，如图24所示，第一密封块630、第二密封块640均为闭孔海绵橡胶防火膨胀材料制成。
进一步的，如图1至图3、图7、图10至图12所示，密封装置5包括支撑板502、斜扁钢板504、嵌压板503和密封防火条501。支撑板502、斜扁钢板504分别安装在门框1上，在门框1与门扇2配合的表面处围绕成两个倒置的凵型。斜扁钢板504与支撑板502平行设置，且位于支撑板502的内侧，朝向支撑板502倾斜。密封防火条501安装在斜扁钢板504和支撑板502之间，密封防火条501垂直于长度方向的截面为直角梯形，梯形的四个角为圆角，梯形的底边贴合门框1。嵌压板503安装在门扇2上，在门扇2与门框1、门扇2与活门槛6配合的表面处围绕成矩形环，在门扇2闭合时，嵌压板503嵌压在密封防火条501上，同时，嵌压板503嵌压在第一密封块630上，能够将密封防火条501和第一密封块630挤压变形而达到密封门扇2与门框1、门扇2与活门槛6之间间隙的效果，实现密闭和防火功能。
进一步的，如图1至图3、图7、图10至图12所示，在支撑板502、斜扁钢板504上，分别与门框1相连的一端为固定端，另一端为自由端，支撑板502的自由端在门框1表面的高度高于斜扁钢板504的自由端在门框1表面的高度。在门扇2闭合时，支撑板502的自由端贴合在门扇2表面，能够支撑门扇2，斜扁钢板504的自由端与门扇2表面具有缝隙，便于密封防火条501的变形以及能够避免门扇2的过定位。
进一步的，如图1至图3、图7、图10至图12所示，密封防火条501为闭孔海绵橡胶防火膨胀材料制成。
进一步的，如图1、图2、图16至图21所示，闭锁4包括基座420、把手410、传动机构430和锁头组件450。基座420和锁头组件450安装在门扇2上，把手410安装在基座420上，传动机构430分别与把手410和锁头组件450相连，锁头组件450与门框1滑动配合，能够伸入门框1中实现闭锁4的锁闭，完全由门框1中滑出后解锁闭锁4。作为优选，本发明的闭锁4为两组，一组闭锁4位于门扇2靠近铰页3的一侧，另一组闭锁4位于门扇2远离铰页3的一侧，从而能够在门扇2的左右两侧锁闭门扇2，锁闭牢固可靠。
