The invention discloses a railway gondola car bottom door opening and closing buffer device which comprises a torsion bar spring mechanism, the torsion bar spring mechanism comprises a torsion bar spring and a connecting rod, the torsion bar spring is in a U shape, one end of the torsion bar spring is connected with a railway gondola car bottom door, the other end of the torsion bar spring is rotationally connected with one end of the connecting rod, the other end of the connecting rod is rotatably connected with a bottom frame of the railway gondola car, a spring buffer structure is arrangedon a bottom door stop of the bottom door of the railway gondola car, and when the bottom door of the railway gondola car is opened, the spring buffer structure is in elastic fit with the bottom door of the railway gondola car. The buffer device reduces opening and closing impact force of the bottom door through the torsion bar spring mechanism and the spring buffer structure, avoids integral deformation of the bottom door, cracking of weld joints, breakage of hinges, increase of gaps of the bottom door and the like, assists the bottom door to be closed through the torsion bar spring mechanism,reduces strength required for closing the bottom door, and reduces working intensity of operators.

    本发明公开了一种铁路敞车底门开闭缓冲装置,包括:扭杆弹簧机构,扭杆弹簧机构包括扭杆弹簧、连杆,扭杆弹簧为U形,扭杆弹簧的一端与铁路敞车底门相连接,扭杆弹簧的另一端与连杆的一端转动连接,连杆的另一端与铁路敞车的底架转动连接,弹簧缓冲结构,弹簧缓冲结构设置于铁路敞车底门的底门挡上,当铁路敞车底门打开时,弹簧缓冲结构与铁路敞车底门形成弹性配合,该缓冲装置通过扭杆弹簧机构和弹簧缓冲结构减轻底门开闭冲击力,避免底门整体变形、焊缝开裂、折页断裂、底门间隙加大等,同时通过扭杆弹簧机构辅助底门关闭,减低底门关闭所需力量,降低操作人员工作强度。
