[0002] Bridges generally refer to structures erected across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; supports are force transmission devices installed at the supporting locations between the span structure and the piers or abutments; ancillary structures refer to bridgehead slabs, conical slope protection, bank protection, diversion projects, etc. When the bridge is in use, a bridge anti-collision device is needed to protect the bridge.

[0003] The bridge anti-collision device based on bridge safety performance in the prior art usually uses simple flexible materials for buffering in actual use, which has poor anti-collision effect and easily causes damage to the bridge. In addition, the height of the bridge anti-collision device is usually fixed, and the height of the bridge and the road surface are uneven during use, resulting in poor practicality and inconvenience in use. Therefore, we propose a bridge anti-collision device based on bridge safety performance, which solves the above problems of using simple flexible materials for buffering, poor anti-collision effect and easily causes damage to the bridge, and the height of the bridge anti-collision device is usually fixed, and the height of the bridge and the road surface are uneven during use, resulting in poor practicality and inconvenience in use.

The top of the lifting rod 3 is fixedly connected to the bottom of the vertical frame 2. The two lifting rods 3 both pass through the control box 4. The lifting rod 3 is used to conveniently limit the control box 4 so that the control box 4 can only move up and down.

[0039] In this embodiment, the inner wall of the vertical frame 2 is symmetrically provided with sliding grooves, and there are two sliding grooves. Sliders are fixedly connected to the left and right sides of the control box 4. The outer walls of the two sliders are slidably connected to the inner walls of the corresponding sliding grooves.

[0043] Working principle: In actual use, the base 1 is placed in a suitable position. When the height of the anti-collision device needs to be adjusted, the threaded rod 8 is rotated. At this time, the threaded rod 8 rotates, which drives the threaded plate 9 connected to the thread to move right. When the threaded plate 9 moves to the right, it pulls the plug plate 19 on the left to move horizontally and pushes the transmission plate 11 to move to the right. When the transmission plate 11 moves to the right, it pushes the inclined push rod 12. When the push rod 12 is thrust, it can rotate to push the transmission plate 11 down. The transmission plate 11 slides downward under the guidance of the guide rod 10. The bottom rotation of the transmission plate 11 is connected to a turntable. The movement of the turntable will slide on the top of the slide plate 13 and push the slide plate 13 down.

At this time, the control box 4 is unlocked and can be pushed to move up and down. When the control box 4 moves, it can drive the rear support plate 30 and the contact plate 7 to move up and down. When the contact plate 7 moves to the appropriate position, it is reset by rotating the threaded rod 8. The threaded rod 8 drives the threaded plate 9 to reset. At the same time, the threaded plate 9 pulls the transmission plate 11 to move horizontally, and the No. 1 spring 14 loses its power. The limit pushes the slide plate 13 to move upward. When the slide plate 13 moves, it will push the transmission plate 11 upward and pull the driving rod 15. At this time, the driving rod 15 will drive the connecting rod 16. At the same time, the two No. 2 springs 18 lose their restrictions and push the threaded plate 9 and the connecting plate 17. The threaded plate 9 and the connecting plate 17 move and drive the plug plate 19 to move. At this time, the plug plate 19 is engaged with the slot to fix the control box 4 in the current position, and the bridge is protected by the contact plate 7. When the contact plate 7 is collided, the contact plate 7 moves backward and pushes the damper 20 to contract. At the same time, the contact plate 7 will drive the push plate 22 to move and compress the No. 3 spring 21. When the push plate 22 moves, it will push the connecting rod 23. The connecting rod 23 will The two reset plates 24 are pushed to move away from each other and compress the No. 4 spring 26. The movement of the reset plate 24 will drive the two auxiliary rods 25 to move away from each other. The movement of the auxiliary rod 25 will drive the push rod 27. At this time, the movement of the push rod 27 will push the movable plate 28 forward. The forward movement of the movable plate 28 will drive the buffer plate 29 to move forward and contact the rear side of the contact plate 7. A rubber pad is provided on the front side of the buffer plate 29. The buffer plate 29 conveniently supports the contact plate 7 to reduce the impact force when the contact plate 7 moves. The cooperation of the No. 3 spring 21 with the No. 4 spring 26 and the buffer plate 29 can conveniently reduce the impact force of the contact plate 7 when it is hit, thereby protecting the bridge.
