The invention discloses a railway gondola car lower side door sealing structure and a gondola car lower side door, and relates to the technical field of railway freight gondola cars, the railway gondola car lower side door sealing structure comprises a circle of groove formed in the edge of the inner side of the lower side door in the circumferential direction and a sealing strip embedded in the groove, the sealing strip partially protrudes out of the groove, the sealing strip is an omega-shaped sealing strip, and the interior of the omega-shaped sealing strip is of a hollow structure. The omega-shaped sealing strip has the rebound value of 0 mm-30 mm, and after the lower side door is closed, the omega-shaped sealing strip makes sealing contact with the side wall door hole plate of the vehicle. The sealing structure is reasonable in design, when the lower side door is pressed on the side wall door hole plate, the sealing strip is compressed, and when the gap between the lower side door and the side wall door hole plate changes, the sealing strip rebounds or is further compressed according to the change of the door slot gap, so that the variable door slot gap sealing of the lower side door is realized.

    本发明公开了一种铁路敞车下侧门密封结构及敞车下侧门,涉及铁路货运敞车技术领域,包括安装在下侧门内侧边缘周向一圈的沟槽、以及镶嵌在沟槽内的密封条,密封条部分凸出沟槽,密封条为“Ω”形密封条,“Ω”形密封条内部中空结构,“Ω”形密封条具备0mm‑30mm的回弹量,关闭下侧门后,“Ω”形密封条与车辆的侧墙门孔板密封接触。本发明设计合理,下侧门压在侧墙门孔板上时,密封条被压缩,当下侧门与侧墙门孔板之间的间隙变化时,密封条根据门缝间隙变化回弹或进一步压缩,以实现下侧门变化门缝间隙密封。
