The invention discloses a side wall opening and closing mechanism for a railroad box car. The side wall opening and closing mechanism for the railroad box car comprises a movable side wall, an upper transmission shaft, an upper transmission shaft shifting fork, an upper crank throw, a first connecting rod, a second connecting rod, a third connecting rod, a connecting plate, a handle, a handle mounting base, a lower transmission shaft, a lower transmission shaft shifting wheel, a lower crank throw, a spring drawing handle, a preloaded spring assembly, a lower rail, a protective rail and a sliding rail; when the handle is rotated, the first connecting rod and the second connecting rod can be driven to finally drive the upper transmission shaft and the lower transmission shaft to rotate; when the upper transmission shaft rotates, the upper transmission shifting fork is driven to drive the movable side wall to move to one side to enable the upper rolling wheel to fall to an upper rail; when the lower transmission shaft rotates, the lower transmission shaft shifting wheel is driven to drive the movable side wall to move to one side to enable the lower rolling wheel of the movable side wall to fall to the lower rail, and the movable side wall can slide along the upper rail and the lower rail at this moment. According to the side wall opening and closing mechanism for the railroad box car, the opening degree of the half side wall of the box car can be achieved, the goods loading and unloading efficiency of the existing box car can be greatly improved, and large goods of the larger size can be loaded.
