Description
本发明涉及轨道交通设备的技术领域，具体地，涉及一种用于站台与车厢之间的填充装置。
由于轨道列车车箱与车站站台之间的“空隙”是防止列车运行时“动态”的车厢碰擦站台影响列车运行安全，然而该“空隙”却给乘客上下车带来了安全隐患(如2014年1月的G39次高铁驶入杭州东站，下车时一名女童跌入车厢与站台之间的“空隙”，2015年10月哈尔滨西G48次高铁出现故障乘客下车透气，一名幼童跌入车厢与站台之间的“空隙”，2016年8月合肥南站G1601次列车，一名小女孩掉入车厢与站台之间的“空隙”，2017年5月广州地铁区庄站，一名72岁女乘客下车时踏空脚被车厢与站台之间的“空隙”卡住)从而导致安全事故的发生。现有技术如橡胶垫安装在站台边虽不影响列车运行的安全但仍有几厘米以上的缝隙甚至(如重庆轻轨嘉州路站本人于2017年07月14日现场测量)间隙约140mm。现有技术虽然缩小了“空隙”但仍不能消深“空隙”安全隐患。
随着社会的发展需要设计一种既不影响列车运行安全又能消除“空隙”给乘客上下车厢带来安全隐患的全新装置。
本发明是根据列车运行时车箱会产生多方向动态的特征和必须保证多方向动态的车厢不碰擦静态站台的安全要求，又根据列车停靠站台时乘客上下车厢行人动态的多变性特征和行人上下车厢踏空掉进车厢与站台之间的“空隙”而发生事故的安全隐患事实；再根据众所周知的球体可多方向运动的特征、活塞箱体可静态的特征，本发明根据这些动态和静态的特征以及车厢和行人的安全要求设计的一种“厢体动而珠或动、珠或动而壁不动”的“随动方法”来满足列车运行经停站台时不碰擦站台的安全要求又满足了列车停靠站台时乘客上下车厢脚无空踏而掉进“空隙”的行人安全要求。
为解决上述技术问题，本发明提供了一种用于站台与车厢之间的填充装置以达到消除列车车厢与站台之间“空隙”，既消除乘客上下车厢的安全隐患又能满足列车运行经停站台时不碰擦站台的安全要求的目的，解决了运动的车箱体与静止的站台边必须存在的“空隙安全”和“空隙安全”给乘客带来的“安全隐患”的“安全”与“隐患”的矛盾问题。
为了实现上述技术效果，本发明所提供的技术方案是：一种用于站台与车厢之间的填充装置，其特征在于，包括一端开口的活塞箱体，所述活塞箱体内沿其开口方向滑动设置有活 塞体，活塞体的一端部与活塞箱体的底部之间设有至少一个弹簧，另一端固定连接有至少一个球套，各个球套内均活动套设有球体且球体的顶部突出所述球套的端面；所述活塞体的侧面上开设有沟槽，活塞箱体的侧壁上沿同一直线方向设有至少两个与沟槽相匹配的限位螺钉。
进一步地，所述活塞体的底部和活塞箱体的底部均设有与所述弹簧端部相套接的弹簧座。
进一步地，所述球套包括球座、与球座螺纹连接的球盖，所述球座的一端部与所述活塞体的端部螺纹连接，另一端部开设有与球体相匹配的内凹球面；所述球盖上开设有与球体相匹配的通孔。
进一步地，所述球体设为实心球体或者空心球体。
进一步地，所述弹簧和球套均设有两个，且对称分布于活塞体的中心线两侧。
进一步地，所述活塞箱体的尾端部设有固定板，固定板上开设有多个螺栓孔。
进一步地，所述限位螺钉在活塞箱体的侧壁上呈等间距排布且与活塞箱体螺纹连接。
进一步地，所述活塞箱体由防腐材料制成。
相比于现有技术，本发明的有益效果是：
1.本发明使钢性运行车厢或进停出站时段不可擦碰静态站台边改变成了钢柔结合且运行车厢可擦碰的随动站台边，这个“随动站台边”的改变不仅能保障列车进出站台行停安全也能彻底消除乘客进出车厢脚下踏空的安全隐患；
2.列车车厢与站台之间的“空隙”可调至车、人皆为安全的范围内从而消除安全隐患；本装置利于机械化生产，现场安装方便且使用寿命长；本装置更换维修几率低且搬运方便，单个体积小，一人施工，无需他人协助，节约人力和财力；
3.本发明的活塞体端部通过球套安装有可自由转动的球体，球结合的活塞体在底部的弹簧作用下活塞体顶部的球或可接触车厢以达到消除站台与车厢之间的间隙至极限；而且活塞体的运动行程可通过活塞箱体的限位螺钉装配至活塞体上的沟槽内进行调节，以适合不同的站台与车厢之间的不同间隙，防止车厢碰擦球体过极使之产生较大的反作力挤压到车厢产生形变。
