Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge protection, and in particular to an emergency anti-collision device for bridges facilitating multiple protections and a working method thereof. Background Art
[0002] With the advancement of my country's urbanization process and the growing prosperity of the national economy, the transportation industry has developed rapidly, especially the large-scale construction of three-dimensional transportation, which has greatly alleviated the pressure on ground transportation. Intertwined overpasses, viaducts and other transportation facilities can be seen everywhere. At the same time, with the rapid increase in vehicles, due to the negligence of drivers or other reasons, bridge collision accidents occur from time to time, causing losses to people's lives and property, and also causing damage to bridges. The economic losses caused by traffic congestion are not small, which seriously affects traffic safety and road traffic.
[0003] The Chinese invention with patent number CN201810111401.2 in the prior art discloses a bridge anti-collision warning device, including a bridge column, the bridge column is connected to the bridge pier, the bridge column fixes a first curved plate, the first curved plate is connected to the second curved plate, the second curved plate is connected to the third curved plate, the third curved plate is connected to the fourth curved plate, and the fourth curved plate is connected to the fifth curved plate; the fourth curved plate indirectly links the rack, the rack meshes with the first gear, and the first gear is connected to the water pump through transmission; the invention achieves the purpose of reducing the impact force on the bridge column by setting up a multi-layer anti-collision device, and the equipment can also be restored to its original state and reused after the collision. In this process, the gear and the rack cooperate, and the impact force drives the rack to rotate, so that the rack and the gear mesh and transmit, and the rotation of the gear can drive the water pump at the lower end to rotate, and the gravity of the water pump itself and the reaction force of the water on itself will weaken the impact force.
[0004] The above invention only protects the bridge columns on the bottom side of the bridge. In the process of driving on the bridge, unexpected situations may occur, such as brake failure or a vehicle collision in front. In order to reduce losses and protect their own safety, the driver will generally slow down and stop the vehicle by friction between the vehicle and the guardrail on the side of the bridge. In order to prevent the vehicle from losing control and running off the bridge after a collision, the existing bridge anti-collision guardrail is simply made of soft materials for shock absorption, and the shock absorption performance is poor. Since the vehicle travels too fast, it will still cause great harm to the vehicle and personnel in the event of an accident, causing damage to the vehicle and personnel, and the safety performance of the bridge is poor.

[0017] 1. The bridge emergency anti-collision device and working method which facilitate multiple protection can buffer the impact force of the vehicle by arranging a shock-absorbing component. When buffering the impact force of the vehicle, the guide mechanism can redirect the impact direction of the vehicle to prevent the buffer plate from bearing the entire impact force of the impact vehicle. Then, the resistance-increasing mechanism is used to increase the moving resistance of the impact vehicle, further reducing the impact speed of the vehicle, thereby improving the safety of bridge use and reducing the damage to the vehicle and guardrail after the collision.
[0018] 2. The bridge emergency anti-collision device and working method for facilitating multiple protections are as follows: when the buffer plate is forced to approach the first mounting plate, the swing arm automatically deflects and drives the first rack to move in the buffer plate, so that the first rack is meshed with the first gear on the first rotating rod for transmission, and the first rotating rod drives the first rubber roller to rotate, so that the rotating first rubber roller drives the vehicle to change direction, and the vehicle deviates from driving toward the first mounting plate to driving toward the second mounting plate, thereby reducing the direct collision force of the buffer plate on the vehicle, increasing the service life of the device, and reducing the damage to the vehicle and guardrail after the collision.
[0019] 3. The bridge emergency anti-collision device and working method that facilitate multiple protections are as follows: after the buffer plate is forced to approach the first mounting plate, the first rubber roller and the second rubber roller simultaneously contact the side of the vehicle, and the vehicle continues to rub against the second rubber roller during the collision and drives the second rubber roller to rotate, and the second rubber roller drives the second rotating rod and the resistance plate and the second gear on the second rotating rod to rotate, and the resistance plate rotates in the water storage cavity in the first ear plate, and contacts with the water during the rotation of the resistance plate, and the water increases the rotation resistance of the resistance plate, and increases the friction between the second rubber roller and the side of the vehicle, thereby reducing the collision speed of the vehicle and reducing the damage to the vehicle and the guardrail after the collision.

[0035] A buffer plate 3, wherein a shock absorbing assembly 4 is arranged between the buffer plate 3 and the first mounting plate 1;
[0036] A guide mechanism 5, which is arranged on the buffer plate 3 and is used to guide the driving direction of the vehicle;
[0037] A second mounting plate 6, the second mounting plate 6 is fixed on the guardrail 2 and connected to the first mounting plate 1; and
[0038] The resistance increasing mechanism 7 includes a resistance increasing component and a driving component connected to the resistance increasing component. The resistance increasing component is arranged on the second mounting plate 6, and the driving component is arranged on the first mounting plate 1.
[0039] Specifically, when the device is used, the first mounting plate 1 and the second mounting plate 6 are installed on the bridge guardrail 2 by bolts. When an emergency occurs in the vehicle, when the driver drives the vehicle to collide with the bridge guardrail 2, the buffer plate 3 on the outside of the first mounting plate 1 is forced to move, and the shock absorbing component 4 can perform the first buffering of the collision force. When buffering the collision force of the vehicle, the guide mechanism 5 can redirect the collision direction of the vehicle to prevent the buffer plate 3 from bearing the entire collision force of the vehicle. Subsequently, the resistance increasing mechanism 7 is used to increase the movement resistance of the colliding vehicle, and the collision speed of the vehicle is further reduced, thereby improving the safety of bridge use and reducing the damage to the vehicle and the guardrail 2 after the collision.
[0040] Embodiment 2:
[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig. 9 , a bridge emergency anti-collision device that facilitates multiple protections.

[0042] Specifically, when an emergency occurs in the vehicle and the driver drives the vehicle to collide with the bridge guardrail 2, the buffer plate 3 on the outside of the first mounting plate 1 moves under the force, and the buffer plate 3 drives the movable rod 402 to move into the movable groove 401, and the first elastic element 403 is squeezed. The first elastic element 403 is deformed to buffer and weaken the force exerted on the buffer plate 3.
[0043] Embodiment 3:
[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , a bridge emergency anti-collision device that facilitates multiple protections. On the basis of Example 2, further, the guide mechanism 5 includes a plurality of first rotating rods 501 rotatably arranged on the buffer plate 3, a first rubber roller 502 is arranged on the outer side of the first rotating rod 501, and a first gear 503 is arranged on the upper and lower sides of the first rotating rod 501. The buffer plate 3 is also slidably connected to a first rack 504 that meshes with the first gear 503, and a swing rod 505 is movably connected to the outer side of the first rack 504. The end of the swing rod 505 away from the first rack 504 is connected to the first mounting plate 1, and a second elastic element 5041 is also arranged between the first rack 504 and the buffer plate 3.
[0045] Specifically, when an emergency occurs with a vehicle, the driver drives the vehicle toward the bridge guardrail 2, and the buffer plate 3 on the outside of the first mounting plate 1 moves under the force. When the buffer plate 3 approaches the first mounting plate 1, the swing rod 505 automatically deflects and drives the first rack 504 to move in the buffer plate 3. The second elastic element 5041 is squeezed and deformed to further buffer and weaken the impact force. When the first rack 504 moves, it meshes and transmits with the first gear 503 on the first rotating rod 501. The first rotating rod 501 drives the first rubber roller 502 to rotate, so that the rotating first rubber roller 502 exerts force on the vehicle and drives the vehicle to change the collision direction. The vehicle deviates from driving toward the first mounting plate 1 to driving toward the second mounting plate 6, thereby reducing the direct collision force of the vehicle on the buffer plate 3 and improving the service life of the device and the bridge.
