The invention relates to the technical field of freight trains, and particularly relates to a reinforced freight train carriage top cover. The top cover comprises a carriage mechanism and a top covermechanism, wherein the top cover mechanism comprises a top frame, the two sides of the outer wall of the top of the top frame are rotationally connected with expansion doors through hinges, a top curtain is riveted between the outer walls of the sides, which are away from the top frame, of the two expansion doors, side curtains are riveted between the outer walls of the other two sides of the expansion doors, the ends, which are close to the top curtain, of the two side curtains are sewn with the top curtain through silk threads, supporting frames distributed at equal intervals are bonded to the outer wall of the bottom of the top curtain, mounting blocks are welded to the four corners of the outer wall of the top of the top frame, expansion hydraulic cylinders are mounted in the mountingblocks through bolts, and connecting mechanisms are rotatably connected to the ends, which are away from the mounting blocks, of the expansion hydraulic cylinders. The top cover has the beneficial effects that when freight are high, the expansion doors can be opened, the top curtain and the side curtains can still enable the opening to be in a sealed state at the moment, the top cover can adapt tothe height of the freight, and the top of the freight can be prevented from being directly exposed.

    本发明涉及技术领域,具体是一种加固型货运火车车厢顶盖,包括车厢机构和顶盖机构,顶盖机构包括顶架,顶架顶部外壁的两侧均通过铰链转动连接有扩展门,两个扩展门远离顶架的一侧外壁之间铆接有顶帘,且扩展门另外两侧外壁之间铆接有侧帘,两个侧帘靠近顶帘的一端均通过丝线与顶帘缝合,且顶帘的底部外壁上粘接有呈等距离分布的支撑架,顶架顶部外壁的四角处均焊接有安装块,且安装块的内部通过螺栓安装有扩展液压缸,扩展液压缸远离安装块的一端转动连接有连接机构。本发明的有益效果,当货物较高时,能够将扩展门打开,此时顶帘和侧帘依旧能够使得开口处处于密封状态,既能够适应货物的高度,也能够防止货物的顶部直接暴露。
