A secondary locking device, comprising a first transmission shaft (1), a second transmission shaft (2), a clutch, a pressure mechanism and a reset mechanism; under the pressure of the pressure mechanism, the clutch enables the first transmission shaft (1) to separate from the second transmission shaft (2); and under the action of the reset mechanism, the clutch enables the first transmission shaft (1) to engage with the second transmission shaft (2). The secondary locking device can be used for the bottom door of a hopper car, so that the bottom door of the hopper car opening and closing after passing over dead center in a flat four-bar linkage is more reliable.
