[0025] As Figures 1 - 5 shown, in the enhanced safety guardrail device for municipal transportation provided in this embodiment, two chutes 2, four threaded holes 3 and four mounting holes 4 are provided on the upper surface of the base 1. The two chutes 2 are symmetrically distributed about the central axis of the base 1. The four mounting holes 4 are located at the four corner positions of the base 1. Two fixed base plates 5 are provided on the upper surface of the base 1. The two fixed base plates 5 are symmetrically distributed about the central axis of the base 1. Two straight slots 6 are provided on the fixed base plate 5. The straight slots 6 are parallel to the chutes 2. A first bolt 7 is threadedly connected in the threaded hole 3. The first bolt 7 is slidably connected to the straight slot 6. A flat washer 8 is sleeved on the first bolt 7. The lower surface of the flat washer 8 is in contact with the fixed base plate 5;

[0026] A U-shaped vertical plate 9 and two fastening vertical plates 10 are fixedly connected to the upper surface of the fixed base plate 5. The two fastening vertical plates 10 are both fixedly connected to the U-shaped vertical plate 9. The U-shaped vertical plate 9 is located between the two fastening vertical plates 10. A second bolt 11 for locking the two adjacent fastening vertical plates 10 is provided on the two adjacent fastening vertical plates 10. A nut 12 is threadedly connected to the second bolt 11. The mounting hole 4 is used to fix the base 1. The threaded hole 3 is used for the fixed base plate 5. The straight slot 6 is used to provide conditions for the movement and fixation of the fixed base plate 5. The first bolt 7 is used to fix the fixing plate. The U-shaped vertical plate 9 and the fastening vertical plates 10 are used to fix the support rod 15. The second bolt 11 and the nut 12 are used to lock the two adjacent fastening vertical plates 10.

[0027] Secondly, as Figure 2 and Figure 4 shown, fixed convex blocks 13 are fixedly connected to the side surfaces of the two U-shaped vertical plates 9 close to each other. A slider 14 is fixedly connected to the side surface of the U-shaped vertical plate 9 far from the fixed convex block 13. The two sliders 14 are slidably connected to the two chutes 2 in one-to-one correspondence. The fixed convex block 13 is used to cooperate with the fixing hole 16 to fix the support rod 15. The slider 14 and the chute 2 are used to make the movement of the fixed base plate 5 stable.

[0028] Furthermore, as Figure 2 and Figure 4As shown, there is a support rod 15 between two U-shaped vertical plates 9. Fixing holes 16 are formed in the side wall of the support rod 15. Two fixing bumps 13 are located in the fixing holes 16. The outer wall of the fixing bump 13 is in contact with the inner wall of the fixing hole 16. Two cross bars 17 are fixedly connected together on the side surfaces of the two support rods 15 close to each other. Two buffer fixing members 170 are fixedly connected together on the side surfaces of the two cross bars 17 close to each other. Two groups of buffer cylinders 18 are fixedly connected to the buffer fixing member 170. The two groups of buffer cylinders 18 face in opposite directions.

[0029] Furthermore, as Figure 1 and Figure 5 shown, two limiting grooves 19 are formed in the inner wall of the buffer cylinder 18. The two limiting grooves 19 are symmetrically distributed about the central axis of the buffer cylinder 18. A buffer rod 20 is slidably connected to the inner wall of the buffer cylinder 18. Two limiting blocks 21 are fixedly connected to the outer wall of the buffer rod 20. The limiting blocks 21 are slidably connected with the limiting grooves 19. A spring 22 is fixedly connected to the inner bottom wall of the buffer cylinder 18. The other end of the spring 22 is fixedly connected to one end of the buffer rod 20. The other ends of the two buffer rods 20 in the same group are fixedly connected together with a buffer plate 23. The two buffer plates 23 are respectively located at the side positions on both sides of the cross bar 17. The limiting grooves 19 and the limiting blocks 21 are used to limit the movement of the buffer rod 20. The buffer plate 23 is used to enlarge the buffer area. The spring 22 plays a buffering role.

[0030] Even further, as Figure 1 and Figure 2 shown, a protective cover 24 is clamped on the side wall of the base 1. The protective cover 24 is slidably connected with the support rod 15. The protective cover 24 is used for dust and rain protection and for aesthetics.

[0031] As Figures 1 - 5 shown, the principle of the municipal transportation safety enhanced guardrail device provided in this embodiment is as follows: When installing the guardrail device on the road, first, the base 1 is firmly fixed to the road through the installation holes 4. The support rod 15 is inserted between the two U-shaped vertical plates 9. The U-shaped vertical plate 9 is moved to insert the fixing bump 13 into the fixing hole 16. Then, the fastening vertical plates 10 on both sides of the U-shaped vertical plate 9 are locked with the second bolts 11 and nuts 12. At this time, the U-shaped vertical plate 9 and the support rod 15 are tightly fixed together. The fixing bump 13 and the fixing hole 16 are in close fit. Then, the first bolt 7 is locked to tightly fix the fixing base plate 5 and the base 1 together. In this way, the two support rods 15 are fixed;

[0032] When the buffer plate 23 is subjected to an external force, the buffer plate 23 will drive the buffer rod 20 to compress the spring 22. The spring 22 will buffer the external force so that the external force will not directly act on the cross bar 17, increasing the stability of the guardrail device.
