The invention discloses a double-layer sealing unloading opening of a transport railway hopper car, and relates to the technical field of hopper cars. Comprising two end funnel assemblies which are transversely arranged, a first side funnel assembly which is connected between the edges of one sides of the two end funnel assemblies, and a second side funnel assembly which is connected between the edges of the other sides of the two end funnel assemblies. Inner-layer sealing structures are arranged on the inner sides of openings below the first side funnel assembly and the second side funnel assembly; outer layer sealing structures are arranged on the outer sides of the lower openings of the end funnel plate assemblies, the first side funnel assembly and the second side funnel assembly in an embedded mode, and the lowest position of the inner layer sealing structure is lower than the lowest position of the outer layer sealing structure. When the bottom door plate makes contact with the funnel opening, the layer sealing structure is firstly extruded, then the outer layer sealing structure is extruded, and the four corners of the frame extrude the outer layer sealing structure to eliminate gaps at the connecting positions, so that the sealing effect is achieved.
本发明公开了一种运输铁路漏斗车双层密封卸货口,涉及漏斗车技术领域,包括呈横向设置的两个所述端漏斗组件、连接两个所述端漏斗组件一侧边缘之间的第一侧漏斗组件以及连接两个所述端漏斗组件另一侧边缘之间的第二侧漏斗组件。所述第一侧漏斗组件以及所述第二侧漏斗组件下方开口处内侧均设置内层密封结构;各所述端漏斗板组件、所述第一侧漏斗组件以及所述第二侧漏斗组件下方开口处外侧均通过镶嵌形式设置有外层密封结构,所述内层密封结构最低位置低于所述外层密封结构的最低位置。本发明的底门板接触漏斗口时先挤压层密封结构,再挤压外层密封结构,框架四角由于挤压外层密封结构消除连接处的间隙,达到密封的效果。
