description 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
