The invention discloses a roof structure of a railway hopper car with a cover, which relates to the technical field of transportation equipment and comprises a fixed top cover component and a movable top cover component arranged on the fixed top cover component. The fixed top cover assembly comprises an arc-shaped framework, a top plate arranged on the arc-shaped framework and a longitudinal loading opening frame longitudinally arranged in the middle of the top plate. The movable top cover assembly comprises a square loading opening cover assembly, a circular top cover plate assembly, a top cover support, a top cover cross beam assembly, a top cover longitudinal beam assembly and a circular loading opening locking device. The square loading opening cover assemblies are arranged at the longitudinal loading opening frames in a sealed mode, translation of the square loading opening cover assemblies is achieved through pneumatic control, a plurality of round loading openings are formed in the square loading opening cover assemblies, the round top cover plate assemblies are arranged at the round loading openings in a sealed mode, and round loading opening locking devices are arranged at the round top cover plate assemblies. By means of the arrangement of the double-layer top cover and the multiple feeding ports, the technical problem that when a sliding rail deforms or a roller bearing is rusted, movement of the top cover is blocked is solved.

    本发明公开了一种铁路有盖漏斗车车顶结构,涉及运输装备技术领域,包括固定顶盖组件和设置在固定顶盖组件上的活动顶盖组件;固定顶盖组件包括弧形骨架、设置弧形骨架上的顶板以及呈纵向设在顶板中部的纵向装货口框;活动顶盖组件包括方形装货口盖组件、圆形顶盖板组件、顶盖支座、顶盖横梁组件、顶盖纵向梁组件以及圆形装货口锁闭装置;方形装货口盖组件密封设置在纵向装货口框处且通过气动控制实现方形装货口盖组件的平动,方形装货口盖组件上设有多个圆形装货口,圆形顶盖板组件密封在圆形装货口处,各圆形顶盖板组件处设置有圆形装货口锁闭装置。本发明采用双层顶盖以及多个进料口的设置,解决了当滑动轨道变形或滚轮轴承锈蚀时,存在顶盖运动卡滞的技术问题。
