Description

过线孔密封装置、车厢及轨道车辆 技术领域
本申请涉及轨道车辆技术，尤其涉及一种过线孔密封装置、车厢及轨道车辆。
背景技术
轨道车辆的端墙上设有多种连接器，相邻的两个车厢之间通过连接器实现电力和通信的连接，以保障车辆的正常行驶。多种连接器按功能可分为电力连接器和通信控制连接器两种；其中，电力连接器的作用是连接车辆供电主干线，贯通全列；通信控制连接器主要用于列车通信和控车。
图1中示出了相关技术中轨道车辆端墙的结构简图；图2中示出了相关技术中过线孔防护结构的简图；请参照图1-图2。在相关技术的方案中，轨道车辆的端墙10上设有位于地板上方的通信连接器110、重连连接器120和DC110V电力连接器130，位于地板下方的DC600V电力连接器140。其中，DC110V电力连接器130的线束131需要从地板11下方引出，穿过缓冲梁12上翼面的过线孔101后连接至端墙10上的DC110V插座上。为了防止冷凝水等穿过过线孔101流入地板11下方的线槽150内，相关技术方案中通过在过线孔101处设置护套进行防护。具体的，护套包括小护套160和套设在小护套160外的大护套170，其中，小护套160与过线孔101的孔径大体相同，并且与缓冲梁12周圈焊接；大护套170套设在小护套160外侧，且与缓冲梁12和端墙10焊接。大护套170的高度高于小护套160，大部分冷凝水会存储在大护套170和小护套160之间的间隙内而不会流入过线孔101下方的线槽150，从而起到防护作用。
但是，采用相关技术中的方案，由于大护套170和小护套160均呈敞口状态，车厢内的热空气与车厢外的冷空气会在护套的敞口处进行冷热交换，从而 也会产生一定量的冷凝水，此部分冷凝水会直接进入过线孔101下方的线槽150中，从而影响DC600V电力连接器的绝缘性能。

具体实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
实施例一
图3中示出的是本申请一实施例提供的过线孔密封装置的使用状态图；图4中示出的是本申请一实施例提供的过线孔密封装置的结构简图；图5中示出的是本申请一实施例提供的过线孔密封装置的剖视图；图6中示出的是本申请一实施例提供的弹性块的结构简图；请参照图3-图6。本实施例提供了一种过线孔密封装置200，用于密封缓冲梁22上翼面上的过线孔201。由于端墙20上的连接器需要从车体地板21下方引线，线束202需要穿过缓冲梁22上翼面上的过线孔201后才能与连接器进行连接，但是在此过程中由于在缓冲梁22上开设了过线孔201，因此车厢内的热空气和车厢外的冷空气会在过线孔201处产生冷热交换，进而产生冷凝水而存积在地板21下方的线槽204内，影响安装在线槽内的DC600V电力连接器的绝缘性能，带来安全隐患。
本实施例的过线孔密封装置200用于将过线孔201密封，以防止在过线孔201处产生冷凝水。过线孔密封装置200包括密封框210、至少一个过线模块220、弹性块230和至少一个隔板240。
其中，密封框210与缓冲梁22密封连接且遮挡过线孔201；密封框210 可选为非金属框或金属框，例如为金属框；当选用金属框时，密封框210与缓冲梁22可以采用焊接连接的方式进行连接固定；当选用非金属框时，密封块210与缓冲梁22可采用密封胶粘接固定。密封框210的横截面与过线孔201相似，可以呈矩形、圆形等规则形状，也可以呈其他不规则形状。密封框210在过线孔201的外周侧将过线孔201围挡住，从而遮挡住过线孔201。为了保证线束202的正常通过，密封框210包括中空腔体以及连接中空腔体的第一开口和第二开口，第一开口位于密封框210朝向过线孔201的一侧；第二开口位于密封框210背离过线孔201的一侧；中空腔体、第一开口和第二开口的设置可以保证线束穿过过线孔201后可以再通过密封框210而实现正常的引线。
进一步地，为保证将开口密封，防止冷热空气交换产生冷凝水，在密封框210内还设有过线模块220、弹性块230和隔板240。
过线模块220设置在中空腔体内且与密封框210密封连接，过线模块220与密封框210直径可以涂抹密封胶以提高密封性能。过线模块220可设置在中空腔体的第一端，过线模块220整体呈筒状，过线模块220包括至少一个用于供线束穿过的第一通孔221(如图4所示，本实施例中设有两个第一通孔221)，线束202可通过第一通孔221穿出密封框210。线束202与第一通孔221之间可采用过盈连接的方式连接配合，从而保证密封性。
过线模块220可以采用弹性材料制成，例如可以为橡胶模块；第一通孔221沿过线孔201的轴向贯穿过线模块220，从而降低加工难度；当然，第一通孔221也可以沿与过线孔201的轴向倾斜的方向设置，从而可以使得第一开口和第二开口处的孔位彼此错位，有利于降低车厢内外的冷热空气交换的速率。
为了适应不同直径的线束202的通过，过线模块220可采用可变径的结构。例如，过线模块220包括互相套设的多个直径不同的橡胶筒，相邻的两个橡胶筒之间可拆卸连接，当线束202的直径大于当前过线模块220的直径时，可以采用将内部直径较小的橡胶筒拆卸下来以扩大第一通孔221的直径，使之 与线束202的直径相匹配。
弹性块230设置在中空腔体内且与密封框210密封连接，弹性块230设置在中空腔体的第二端与过线模块220相对。弹性块230主要通过自身的弹性变形来挤压过线模块220，从而使得第一通孔221与线束202之间的密封性能更佳。
隔板240位于过线模块220与弹性块230之间且可沿中空腔体移动，隔板240可采用硬质板材，如金属板。通过隔板240将两个柔性物体隔离开，可以防止柔性物体与柔性物体直接接触时布局变形不均匀的现象。利用弹性块230推动隔板240移动后再将推力均匀的传递至过线模块220上，可以保证过线模块220变形的稳定性。
可选地，本实施例的过线孔密封装置200包括多个过线模块220和多个隔板240，相邻的两个过线模块220之间通过隔板240分隔开，通过设置多个过线模块220可以适应多根线束202的正常通过，从而保证正常的通信或供电需求。
本实施例的隔板240包括主体和设置在主体两端的连接梁241，主体设置在中空腔体内且与中空腔体的侧壁抵接，两个连接梁241分别伸出第一开口和第二开口且搭接在密封框210上。在受到弹性块230推力的作用时，隔板240即可沿中空腔体移动，从而挤压过线模块220，使得线束202与过线模块220密封连接。
本实施例的弹性块230包括弹性主体231、第一金属板232和第二金属板233，弹性主体231例如可选为橡胶主体。第一金属板232位于弹性主体231朝向第一开口的一侧，第二金属板233位于弹性主体231朝向第二开口的一侧，弹性主体231、第一金属板232和第二金属板233例如可采用硫化工艺一体成型。第一金属板232上设有第二通孔，压紧件234可穿过第二通孔并抵接在弹性主体231上，从而使得弹性主体231产生形变以推动隔板240。本实施例中第二通孔可选为螺纹孔，压紧件234可选为螺栓。
通过上述设置，本实施例利用过线模块220、弹性块230和隔板240共同遮蔽住第一开口和第二开口，从而实现了对过线孔201的密封，达到了防止冷凝水产生的目的。
本实施例通过密封框210与缓冲梁22的密封连接将过线孔201遮挡住，并通过过线模块220、弹性块230和隔板240共同遮蔽住第一开口和第二开口以将过线孔201密封，在保证线束202能够正常穿过的前提下实现了对过线孔201处的密封，从而阻止了车厢内的热空气与车厢外的冷空气的在过线孔201处产生冷热交换，降低了冷凝水产生的几率，提高了DC600V电力连接器的绝缘性能。
实施例二
本实施例提供一种车厢，包括车体，车体包括缓冲梁，缓冲梁上设有过线孔，过线孔的上方设有如上实施例一所述的过线孔密封装置。
具体的，图3中显示出了本实施例车厢的局部结构，请参照图3。本实施例的车体包括地板21和设置在地板21一端的端墙20，缓冲梁22设置在地板21下方靠近端墙20的一侧，缓冲梁22沿车体的宽度方向延伸。也就是说，位于地板21上方及端墙20右侧的空间属于车厢内部空间，位于地板21下方的空间属于车外空间，缓冲梁22垂直于图3所示方向延伸。
其中，缓冲梁22包括相对设置的上翼面、下翼面以及连接上翼面和下翼面的侧面，上翼面抵接在地板21的下方，过线孔201开设在上翼面上。
可选地，过线孔201开设在上翼面位于车体宽度方向的两端，过线孔201的轴线垂直于上翼面。
侧面朝向车体内的一侧还连接有线槽204，线槽204内安装有DC600V电力连接器203，DC600V电力连接器203的主体背离线槽204设置，车体下方的线束202穿过线槽204后从过线孔密封装置200穿出，进而与端墙上相应的连接器插座相连接。
本实施例的车厢由于采用了上述实施例一所述的过线孔密封装置，因此可以在保证线束能够正常穿过的前提下实现了对过线孔处的密封，从而阻止了车厢内的热空气与车厢外的冷空气的在过线孔处产生冷热交换，降低了冷凝水产生的几率，提高了DC600V电力连接器的绝缘性能。
实施例三
本实施例提供一种轨道车辆，包括多个首尾相连的车厢，多个车厢中的至少一个采用如上实施例二所述的车厢。
