[0029] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment

[0031] As Figure 1 shown, a double-deck railway freight car includes a vehicle body 1 and at least one lifting device 2.

[0032] End doors 3 are provided at both ends of the vehicle body 1 to facilitate putting goods into the vehicle body 1; the two sides of the vehicle body 1 are side walls 4; the bottom of the vehicle body 1 has a roof 5, which plays a certain protective role for the goods in the vehicle body 1.

[0033] The bottom of the vehicle body 1 is provided with wheels 6 and a braking device 7, and the braking device 7 is used to drive the wheels 6 to rotate, so as to drive the vehicle body 1 to run on the track.

[0034] As Figure 2 shown, the lifting device 2 includes an even number of lifting members and a lifting platform 8. The even number of lifting members are all arranged in the vehicle body 1 and are symmetrically arranged; As Figure 3 shown, the lifting member includes a fixing frame 9, a lead screw 10 and a motor 11; A plurality of the fixing frames 9 are vertically fixed on both sides inside the vehicle body 1; The lead screw 10 is vertically and rotatably arranged in the fixing frame 9; The motor 11 is arranged on the fixing frame 9 and is used to drive the lead screw 10 to rotate.
