Due to the design of the top cover 5, it can prevent rainwater from entering the fixed cylinder 2 in rainy weather, thereby preventing the top of the vehicle from getting damp. A connecting rod 6 is inserted into the top inner wall of the top cover 5. The bottom end of the connecting rod 6 is fixed with a connecting plate 7 by bolts. Two movable rods 8 are inserted through the bottom of the connecting plate 7. The bottom end of the movable rod 8 is fixed with a fixed column 4 by bolts. A first spring 10 is sleeved on the circumferential side of the movable rod 8. With the cooperation of the fixed column 4, the connecting rod 6, the connecting plate 7, the movable rod 8 and the first spring 10, the fixed column 4 will be inserted into the screws connecting the top cover and the vehicle. Thus, when using the top cover device of railway locomotives and rolling stock, it can avoid the shaking of the railway locomotive during driving, prevent loosening between the railway locomotive and its top cover, and ensure the long-term use of the railway locomotive and rolling stock. A limiting block 9 is sleeved on the top end of the movable rod 8. A plurality of fixing holes 11 are opened on the circumferential outer side of the top cover 5. An inserting rod 12 is inserted into the fixing hole 11. The design of the inserting rod 12 inserted into the fixing hole 11 can fix the top cover 5, and further fix the fixed column 4. A fixing plate 13 is sleeved on the circumferential side of the fixed cylinder 2. Two housings 14 are fixed on the upper surface of the fixing plate 13 by bolts. The inserting rod 12 passes through the housing 14.

[0033] Between the two sides of the inner wall of the housing 14, two guide rods 15 are inserted. On one side of the guide rod 15, a T-shaped slide plate 17 is slidably connected. One end of the insertion rod 12 is fixedly connected to the T-shaped slide plate 17. And on one side of the guide rod 15, a second spring 16 is sleeved. Two notches 18 are opened at the bottom of the housing 14. The bottom end of the T-shaped slide plate 17 is located in the notch 18. Protective covers 19 are fixed to the inner walls on multiple sides of the top cover body 1 by bolts. A protective pad 20 is adhered to the upper surface of the top cover body 1. The protective pad 20 can protect the top of the top cover body 1 to avoid corrosion and scratching of the top of the top cover body 1 in the external environment, extending the service life of the top cover device. Multiple connecting columns 21 are integrally formed at the top of the inner wall of the top cover body 1. Multiple connecting cylinders 22 are integrally formed at the bottom of the protective cover 19. The connecting columns 21 pass through the connecting cylinders 22.

At the same time, align the positioning bucket 24 with the positioning pin on the top of the vehicle and insert it. Subsequently, the operator pulls the T-shaped slide plate 17 to move to both sides by hand, and the second spring 16 is compressed, so that the insertion rod 12 is separated from the fixing hole 11. Subsequently, the top cover 5 is removed, and then the fixing column 4 is taken out through the connecting rod 6. Immediately afterwards, screws are placed in the limit ring 3. Then, a tool is used to turn the screws to fixedly connect the limit ring 3 to the top of the vehicle, and then fixedly connect the fixing cylinder 2 to the top of the vehicle, so as to install this top cover device. After that, the top cover 5 is sleeved on the top end of the fixing cylinder 2, so that the fixing column 4 is inserted into the groove on the top of the screw. At this time, the fixing hole 11 and the insertion rod 12 are corresponding. Then, under the resilience of the second spring 16, the T-shaped slide plate 17 is reset, and then the insertion rod 12 is inserted into the fixing hole 11, so as to fix the top cover 5, and then fix the connection between the fixing column 4 and the screw, so as to prevent the top cover device from loosening from the vehicle during use and ensure the long-term use of this top cover.
