Abstract

一种用于铁路客车旅客通道的双包折篷风挡，由端框1、折篷2连接构成。折篷2包括内环3、外环4、端部铝环6、中部铝环7、内层敷贴层8；端框1上设有橡胶端框密封条5。该风挡具有良好的伸缩、密结、隔热效果，解决了冬季风挡内侧结冰、风挡布破裂、风挡损坏严重的问题；该风挡的中低频隔声性能特别好，能满足所有高速列车对计权隔声指数的要求。

Description

双包折篷风挡
                       技术领域
本实用新型涉及一种铁路客车旅客通道风挡，特别涉及一种双包折篷风挡。
                       背景技术
现有的铁路客车旅客通道风挡有两种：一种是地面干线车辆使用的，其风挡折棚布环为单层结构，隔热效果差，冬季结冰严重；另一种是地铁车辆使用的，其风挡折棚布环为双层结构，但双层间没设敷贴层，隔热、隔音效果难以满足使用要求。随着地面干线列车速度的提高，冬季风挡内外的温差经常大于30℃，风挡内侧结冰现象越来越严重，致使风挡布破裂，风挡损坏；随着地面干线列车速度的提高，铁路客车旅客通道风挡处已成为严重的振动、噪声辐射源，难以满足高速列车对计权隔声指数的要求。
                        发明内容
本实用新型的目的是提供一种在高速行驶的列车上具有良好隔热、隔声效果，显著减轻风档折棚内层结冰现象，防止风挡布破裂的新型风挡。
本实用新型由端框、折篷连接构成。其中折篷包括内环、外环、端部环、中部环；内环的一端为圆弧形，另一端为直型，多个内环的圆弧端串联连接成一整体，该整体两头的两圆弧端分别通过端部环与端框连接在一起；外环呈圆弧形，多个外环的圆弧端串联连接成一整体，该整体两头的两圆弧端也分别通过端部环与端框连接在一起，并且外环的中部串联处还连接内环的直端，并由中部环加以固定；还包括内层敷贴层，该敷贴层附着在内环或外环或内环和外环上；内环和外环上的圆弧同方向弯曲，端框上设有端框密封条。端框为减震复合钢板结构或非减震型材结构，减震复合钢板结构由“金属/高分子组合材料/金属”三层组成。
铁路客车安装本实用新型后，风档的隔热效果显著提高，风挡内侧结冰现象显著减轻，在高寒地区冬季气温低达-40℃，风挡因内侧结冰而损坏的情况基本排除；该风挡的中低频隔声性能特别好，调节内层敷贴层的厚度和分布，可满足所有高速列车对计权隔声指数的要求。
                       附图说明
附图1为本实用新型实施例的主视图
附图2为本实用新型实施例的侧视图
附图3为本实用新型实施例的A-A向剖视图
                       具体实施方式
下面结合附图，对本实用新型的实施例进行说明：
参考附图1、2，本实用新型实施例由端框1、折篷2连接构成。端框1左右对称，折篷2环包铁路客车旅客通道，左、右视图对称。
参考附图3，折篷2包括内环3、外环4、端部铝环6、中部铝环7；内环3的一端为圆弧形，另一端为直型，多个内环3的圆弧端串联连接成一整体，该整体两头的两圆弧端分别通过端部铝环6与端框1连接在一起；外环4呈圆弧形，多个外环4的圆弧端串联连接成一整体，该整体两头的两圆弧端也分别通过端部铝环6与端框1连接在一起，并且外环4的中部串联处还连接内环3的直端，并由中部铝环7加以固定。
折篷2还包括内层敷贴层8；该敷贴层附着在内环3或外环4或内环3和外环4上，内环3和外环4上的圆弧同方向弯曲，端框1上设有橡胶端框密封条5，端框1为铝合金型材非减震结构。
本实用新型实施例安装于铁路客车车体两端的风挡构架上，两车联挂时由风挡构架上的风挡锁将两车的风挡锁为一体，完成伸缩、密结、隔热、隔声的功能。在本实施例中，内环3和外环4采用进口人造革缝制，中部铝环7与内环3和外环4的联接采用压接方式；端部铝环6与铝合金端框1由螺钉连接。
列车运行中内层敷贴层8的弯曲弧度随内环3和外环4的的弯曲弧度做适应性变化。
