Disclosed is a railway hopper car comprising a car body (), a top cover (), a bogie (), a braking device (), a coupler buffer device (), and a bottom door () and a bottom door opening and closing mechanism () mounted at a discharge port at the bottom of a chassis. The railway hopper car further comprises a longitudinal saddle () disposed in the center of the car body () in the length direction thereof and arranged along the longitudinal direction of the car body (). By providing the longitudinal saddle (), the sequential requirement to close the left bottom door () and the right bottom door () is eliminated, thereby simplifying the structure of the linkage bottom door opening and closing mechanism and reducing manufacture and maintenance costs thereof.

The present invention discloses a connecting rod type two-level locking device, a hopper car bottom door and a hopper car, and belongs to the technical field of rail wagons. The connecting rod type two-level locking device includes a transmission shaft, a door opening arm, a first roller, a second roller, a first locating pin, a standstill locking disk and a linkage mechanism. The hopper car bottom door includes the connecting rod type two-level locking device. The hopper car includes the bottom door. Even if the connecting rod type two-level locking device is accidentally stressed, the linkage mechanism cannot rotate, and at this time, the slave arm cannot rotate neither. The accidental opening of the hopper car bottom door can be avoided. The hopper car is more reliable to use.

The present invention discloses a two-level locking device, a hopper car bottom door and a hopper car. The device includes a first transmission shaft, a second transmission shaft, a clutch, a pressure mechanism and a reset mechanism, wherein under the pressure action of the pressure mechanism, the clutch separates the first transmission shaft from the second transmission shaft, and under the action of the reset mechanism, the clutch joints the first transmission shaft with the second transmission shaft. The bottom door includes the device. The hopper car includes the bottom door. By adopting the device, when the clutch is accidently separated by the pressure action of the pressure mechanism, the reset mechanism can re-joint the clutch to prevent the accidental rotation of the first transmission shaft and the second transmission shaft. By adopting the bottom door, the hopper car bottom door opened and closed by a planar four-bar linkage passing a dead point is more reliable to use. The hopper car is more reliable to use.
