[0035] The above embodiment discloses an anti-falling railway locomotive traction device, wherein when the locomotive needs to be connected to the carriage, the first fixing plate 11 and the second fixing plate 12 are fixed to one side of the locomotive and the outside of the carriage respectively, and then when the connection is made, the locomotive approaches the carriage, and the rounded part on one side of the connecting block 22 guides the limiting column 21, so that the connecting plate 19 slides along the length direction of the second guide rod 18, and then one end of the limiting column 21 is tightly attached to one side of the connecting block 22, and when one end of the limiting column 21 moves to the corresponding position of the limiting slider 23, the rounded part on one side of the limiting slider 23 is pressed against the limiting column 21 guides the limit slider 23 to move into the connection block 22. When the limit column 21 moves to the corresponding position of the limit groove, the first tension spring 20 causes the connecting plate 19 to return to the initial position, thereby connecting the locomotive with the carriage. After the guide groove plate 25 pushes the limit slider 23 to move into the connection block 22, the second tension spring 24 causes the limit slider 23 to be located in the guide groove on one side of the guide groove plate 25, thereby strengthening the connection between the locomotive and the carriage. When the locomotive decelerates, the carriage will push the mounting plate 13 to move due to inertia, and the two damping springs 17 can absorb the impact generated by the tractor, and at the same time, the piston plate slides inside the fixed cylinder 29. Since the cross-sectional area of ​​the air outlet on the fixed cylinder 29 is smaller than the cross-sectional area of ​​the piston plate, the piston plate compresses the air inside the fixed cylinder 29, which can also play a buffering role. At the same time, the air inside the fixed cylinder 29 is transported to the inside of the sliding tube 31 through the connecting tube 30, and the nozzle at one end of the sliding tube 31 sprays the air, thereby cleaning the guide groove on the guide groove plate 25 at the bottom end of the first tension spring 20, preventing excessive dust or particles inside the guide groove from affecting the sliding of the limit slider 23 in the guide groove. When the connection between the connecting plate 19 and the connecting block 22 needs to be released, the push rod 27 is pushed, and the push rod 27 drives a plurality of second connecting rods and a third connecting rod. The second connecting rod pulls the limit slider 23 to move to the inside of the connecting block 22, so that the limit slider 23 is separated from the guide groove plate 25. The third connecting rod pushes one end of the push rod 26 to move to the outside of the connecting block 22 and fits tightly to one side of the connecting plate 19. The push rod 26 pushes the connecting plate 19 to move along the length direction of the second guide rod 18, so that the limit column 21 is disengaged from the limit groove, thereby separating the connecting plate 19 from the connecting block 22.
