技术领域
本发明涉及轨道车辆技术领域，特别是涉及一种设备舱底板的安装结构。
背景技术
现有的轨道车辆，如城市轻轨、客运列车、动车组等，为节省车内空间和便于安装、配置设备装置的管路和线路，通常将相关车辆设备集中设置于车体底架下方，形成车下设备舱。
轨道车辆高速行驶时会产生很强的空气压力波，使得车辆底部和轨道附近的小石块、或其他物体被吸起，为避免这些物体击打设备舱内的车下设备，确保车辆的安全运行，通常在设备舱的底部安装有底板，以将设备舱密封。
请参考图1，图1为现有设备舱底板的安装结构示意图。
如图所示，现有的设备舱底板12包括沿车辆横向方向布置的多块板材(图中示例性地示出三块)，各板材之间通过密封胶条搭接密封，板材与设备舱骨架11之间通过螺栓13固定连接，具体地，在车体两侧，板材与骨架11的边梁通过螺栓13固定，沿车体的横向，板材与骨架11的横梁通过多组螺栓13固定。
然而，上述设备舱底板的安装结构存在下述问题：
为确保底板12安装的可靠性，底板12与骨架11的横梁的连接需要设置多组螺栓13，连接件过多，不仅不方便底板12的安装，也不便于检修，检修时，需要拆卸所有的螺栓13才能进行，检修后还得重新紧固所有螺栓 13实现底板12与设备舱骨架11之间的固定，导致检修工作量过大。
有鉴于此，如何改进设备舱底板的安装结构，能够方便底板的安装，并降低检修工作量，是本领域技术人员目前需要解决的技术问题。
发明内容

该设备舱底板的安装结构，在底板上固设滑轨，滑轨与骨架横梁上设置相互卡合的凹部和凸部；安装时，将底板自设备舱骨架底部倾斜上抬，使其滑轨与骨架横梁卡合，即限定了底板在车体长度方向的位置，在车体两侧，通过连接件将底板固定于骨架边梁即可，显然，本方案中，底板与骨架横梁的连接通过所述凹部与所述凸部的卡合实现，与背景技术相比，省去了底板与骨架横梁之间的连接件，显然，连接件的数量显著降低，使得底板的安装方便快捷；另外，由于连接件数量大幅减小，也就避免了检修时因拆卸过多连接件导致的工作量过大的问题，从而提高了检修效率。
此外，底板与骨架横梁的卡合结构类似于抽拉式结构，该种结构能够提高底板与骨架横梁之间的密封性，确保设备舱的密封性能。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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、完整的描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明的核心是提供一种设备舱底板的安装结构，该安装结构便于底板的安装，且能够降低检修工作量。
轨道车辆的设备舱设置在车体下方，由设备舱骨架、裙板与底板等一起形成密闭的空间，用以设置车下设备、管路和线路等。
其中，设备舱骨架包括骨架边梁和骨架横梁，底板与设备舱骨架连接，以封闭设备舱底部，对设备舱内的车下设备、管线路等进行保护，使其免受车辆运行过程中的石击、冰冻等伤害。
这里需要说明的是，本文中涉及的方位词“横向”均指车体宽度方向，相应地，“纵向”均指车体长度方向，只是为了表述技术方案的清楚及方便；应当理解，所述方位词的使用不应限制本申请请求的保护范围。
请参考图2，图2为具体实施例中设备舱底板的安装结构的横向剖视图。
在一种具体实施例中，本发明提供的设备舱底板的安装结构包括底板30与骨架边梁21的安装结构，及底板30与骨架横梁22的安装结构。
底板30可拆卸固定连接于骨架边梁21。骨架边梁21位于车体两侧，底板30与骨架边梁固21接后，即限定了底板30在车体横向的位置。
请一并参考图3-4；图3为图2中I部位的局部放大图；图4为图3的左视图。
底板30上与骨架横梁22搭接的一侧固接有滑轨31，该滑轨31具有凹部311，骨架横梁22上设有与该凹部311卡合的凸部221，如图4中所示。
具体的方案中，滑轨31可通过焊接的方式固定于底板30，既方便又可靠。当然，也可采用其他固接方式，如螺接等。
如此设计，安装底板30时，可将底板30自设备舱骨架底部倾斜上抬，使骨架横梁22上的凸部221卡入滑轨31的凹部311，即限定了底板30在车体长度方向(纵向)的位置；底板30与骨架横梁22的相对位置确定后，在车体两侧，通过连接件将底板30固定于骨架边梁21，即限定了底板30在车体横向的位置；拆卸底板30时，只需解除底板30与骨架边梁21的连接，在借助外力使滑轨31的凹部311与骨架横梁22的凸部221脱离，即可将底板30自设备舱骨架底部移出。
由上可知，由于底板30与骨架横梁22的连接是通过凹部311与凸部221 的卡合实现的，与背景技术相比，省去了两者之间的连接件，显然，连接件的数量显著降低，使得底板30的安装与拆卸方便快捷；另外，由于连接件数量大幅减小，检修时，也就避免了因拆卸过多连接件导致的工作量过大的问题，能够提高检修效率。
此外，底板30的凹部311与骨架横梁22的凸部221的配合类似于抽拉式结构，该种结构能够提高底板30与骨架横梁22之间的密封性，确保设备舱的密封性能。
可以理解，实际设置时，将凸部设置于滑轨31，将凹部设置于骨架横梁22也是可行的，同样能够方便地实现底板30与骨架横梁22之间的连接。
进一步地，所述安装结构还包括设置于骨架横梁22的压紧块组件40，该压紧块组件40能够将底板30压紧于骨架横梁22，以限制底板30在竖向(即车体高度方向)的位置，提高底板30安装的可靠性。
具体的方案中，压紧块组件40包括过渡座41和压紧块42；其中，过渡座41与骨架横梁22固接，压紧块42安装于过渡座41，能够将滑轨31压紧于骨架横梁22，从而限制底板30在竖向上的移动。
具体地，压紧块42对滑轨31的压紧力可通过紧固件43来实现，如图3中所示，压紧块42通过紧固件43安装于过渡座41，紧固件43竖向设置，通过调整紧固件43的紧固力，即可调整压紧块42作用于滑轨31的压紧力。
具体的方案中，过渡座41上装配压紧块42的安装孔可以设置为纵向长圆孔，即该安装孔为延伸方向平行于车体长度方向的长圆孔。
如此设置，紧固件43可在该安装孔内沿纵向滑动，以根据需要将压紧块42紧固于合适的位置，更好地将底板30压紧。
具体的方案中，压紧块组件40设置于骨架横梁22的中部，以使底板30受到的压紧力均匀分布，避免底板30出现受力不均翘起等不良现象。
当然，若在骨架横梁22上均匀设置几组压紧块组件40也是可行的。
具体的方案中，压紧块组件40的压紧块42可以设置为楔形结构，相应地，滑轨31上与压紧块42配合的平面也为楔形结构，如此，能够最大限度地发挥压紧块42的压紧作用，更好地限制底板30的竖向运动。
设置压紧块组件40后，在安装底板30时，底板30与骨架横梁22连接配 合后，可先调整压紧块42的安装位置，固定好压紧块42后，再将底板30与骨架边梁21连接固定。
通常，底板30由横向布置的多块板材组成，各板材之间通过密封胶条33压紧密封，如图3中所示。
本方案中，底板30具体由两块板材组成，如此可以减少板材之间的连接，确保底板30的密封性。当然，实际设置时，采用多于两块的板材横向布置形成底板30也是可行的。
具体的方案中，底板30可采用铝合金型材；如此，底板30的结构较为平滑，能够确保车体底部结构的平顺性，提高整车的空气动力学性能。
请一并参考图5，图5为图2中II部位的局部放大图。
底板30与骨架边梁21可通过螺栓实现可拆卸固定连接，简便可靠，且便于拆卸。
具体的方案中，底板30上与骨架边梁21连接的一侧设有翻边部301，该翻边部301贴合于骨架边梁21的侧梁211外侧，翻边部301和侧梁211通过螺栓连接。
如此设计，底板30与骨架边梁21连接的部分相互贴合，可以避免该处形成闪缝，造成设备舱密封性不良的问题。
可以理解，如果结构允许，将底板30的翻边部301贴合于骨架边梁21的侧梁211内侧也是可行的，同样能够确保设备舱的密封性。
这里的“外侧”指远离车体中心的一侧，相应地，“内侧”指靠近车体中心的一侧。
实际设置时，还可在翻边部301和侧梁211之间设置密封件32，以进一步提高底板30与骨架边梁21之间的密封性。
以上对本发明所提供的设备舱底板的安装结构进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
