Description

Technical Field

[0001] This invention belongs to the field of bridge protection, and specifically relates to a road and bridge collision protection device. Background Technology

[0002] With the development of infrastructure, various roads and bridges are constantly increasing. Among them, bridges not only exist to cross rivers and seas, but also viaducts have emerged in the development of cities.

[0003] However, both elevated bridges and bridges need to have guardrails added on both sides of the road to prevent vehicles from losing control and running off the road. Currently, bridge guardrails are generally composed of a cement base and a hollow guardrail. When a vehicle loses control, it will violently collide with the guardrail. When the vehicle is traveling too fast, it will break through the guardrail and fall off the road. This situation usually directly leads to vehicle damage and death.

[0004] Therefore, how to protect out-of-control vehicles on the road and prevent them from crashing through guardrails and causing fatalities is an urgent problem that needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a road and bridge collision protection device to solve the problem of out-of-control vehicles crashing into guardrails and leaving the road.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A road and bridge collision protection device includes at least two protective devices installed sequentially along the length of the guardrail. Each protective device includes a base installed on the guardrail, a guide mechanism, a trigger mechanism, and a traction mechanism mounted on the base. The guide mechanism is located on the upper part of the base to guide an out-of-control vehicle to move along the guardrail. The trigger mechanism is located between the guide mechanism and the base to monitor whether the guide mechanism is hit by an out-of-control vehicle. The traction mechanism is located below the guide mechanism and is electrically connected to the trigger mechanism. After the trigger mechanism detects that the guide mechanism has been hit, it sends a signal to the traction mechanism to intercept the out-of-control vehicle.

[0008] Furthermore, the guiding mechanism includes an inverted bracket and a roller vertically rotatably connected within the inverted bracket, with the opening of the inverted bracket located away from the base.

[0009] Furthermore, the triggering mechanism includes a pressure sensor and a buffer component mounted on the base. The number of pressure sensors and buffer components is at least three and they are evenly distributed between the C-shaped fixing frame and the base. One end of the buffer component is connected to the base, and the other end of the buffer component is connected to the C-shaped fixing frame.

[0010] Furthermore, the traction mechanism includes a box fixedly connected to the base. The side of the box away from the base has an opening and is sealed with a membrane. The lower part of the box contains a linear slide, a scissor-type telescopic frame connected to the linear slide, and a traction net set on the scissor-type telescopic frame. The length direction of the scissor-type telescopic frame is perpendicular to the membrane. A moving block is connected to the linear slide. The end of the scissor-type telescopic frame near the base is connected to the moving block. The scissor-type telescopic frame is extended and retracted by the movement of the moving block on the linear slide. There are at least two scissor-type telescopic frames. One end of the traction net is detachably connected to the end of the scissor-type telescopic frame away from the base. The other end of the traction net is connected to the guardrail through a connector. The connector passes through the box and the base. Nails are vertically set on the upper surface of the traction net.

[0011] Furthermore, the end of the scissor-type telescopic frame near the base is Y-shaped, consisting of a fixed rod and a transmission rod. The fixed rod is rotatably connected to the bottom of the housing via a pin, and the transmission rod is fixedly connected to the moving block. A stop bar is provided on the side of the scissor-type telescopic frame with the fixed rod.

[0012] Furthermore, an inclined baffle is provided on the side of the box away from the base, and a sealing film is placed between the inclined baffle and the bottom of the box.

[0013] Furthermore, a rotating shaft is installed inside the box, and the other end of the traction net is connected to and wound around the rotating shaft. The nails are set on the part of the traction net located above the scissor-type telescopic frame.

[0014] Furthermore, a clamp is provided at the end of the scissor-type telescopic frame away from the base, which is used to hold the traction net.

[0015] Furthermore, each enclosure contains a controller and a battery electrically connected to the controller, and the pressure sensor and linear slide in the protective device are both electrically connected to the controller.

[0016] Furthermore, a solar panel connected to the battery is installed on the upper part of the base.

[0017] The significant beneficial effects achieved by this invention are as follows:

[0018] 1. This invention uses multiple protective devices installed sequentially along the guardrail. The guiding mechanism in the protective device buffers and guides the out-of-control vehicle. The triggering mechanism is triggered by the guiding mechanism to issue an interception command to the traction mechanism. The traction mechanism intercepts the out-of-control vehicle that hits the guiding mechanism and fixes the out-of-control vehicle inside the guardrail, effectively solving the problem of out-of-control vehicles crashing into the guardrail and leaving the road.

[0019] 2. The pivot is designed to roll up and hold the traction net, ensuring that the net has sufficient area to wrap around the tires for braking.

[0020] 3. The installation of solar panels can improve the battery life of this application and reduce human intervention. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] like Figures 1-4 As shown, a road and bridge collision protection device includes at least two protection devices installed sequentially along the length of the guardrail 1. In this application, the length of the protection device is 1 meter, and the number of protection devices is set according to the length of the guardrail 1. The protection device includes a base 2 installed on the guardrail 1, a guide mechanism installed on the side of the base 2 away from the guardrail 1, a triggering mechanism and a traction mechanism installed on the base 2. The guide mechanism is installed on the upper part of the base 2 to guide the vehicle to move along the guardrail 1 and avoid running off the road. The base 2 is a steel plate and is fixed to the guardrail 1 by anchor rods.

[0029] The guiding mechanism includes an inverted bracket 3 with an opening away from the base 2 and a roller 4 vertically rotatably connected inside the inverted bracket 3. After the out-of-control vehicle goes out of control, it crashes into the roller 4, and the roller 4 rolls under force to guide the out-of-control vehicle so that the out-of-control vehicle continues to move along the guiding mechanism.

[0030] The triggering mechanism is installed between the guide mechanism and the base 2 to monitor whether the guide mechanism is hit by an out-of-control vehicle. The traction mechanism is installed below the guide mechanism. The traction mechanism and the triggering mechanism are electrically connected. After the triggering mechanism detects that the guide mechanism has been hit, it sends a signal to the traction mechanism to intercept the out-of-control vehicle.

[0031] The triggering mechanism includes a pressure sensor 5 and a buffer 6 mounted on the base 2. There are at least three pressure sensors 5 and three buffers 6, which are evenly distributed between the C-shaped fixing frame 3 and the base 2. One end of the buffer 6 is fixedly connected to the base 2, and the other end of the buffer 6 is fixedly connected to the direction fixing frame. The buffer 6 can be a spring or a rubber buffer pad. After the vehicle hits the roller 4, the C-shaped fixing plate moves towards the base 2 under force and applies pressure to the pressure sensor 5. The pressure sensor 5 generates a pressure signal to indicate that it has been hit.

[0032] The traction mechanism includes a box 7 fixedly connected to the lower part of the base 2. The bottom of the box 7 is in contact with the ground. The side of the box 7 away from the base 2 is open and sealed by a sealing membrane 8. A linear slide 9, a scissor-type telescopic frame 10 connected to the linear slide 9, and a traction net 11 installed on the scissor-type telescopic frame 10 are installed in the lower part of the side of the box 7 near the base 2. The length direction (i.e., the telescopic direction) of the scissor-type telescopic frame 10 is perpendicular to the sealing membrane 8. A moving block 12 is connected to the linear slide 9. The end of the scissor-type telescopic frame 10 near the base 2 is connected to the conveyor block. The movement of the moving block 12 on the linear slide 9 drives the scissor-type telescopic frame 10 to extend. The extension of the scissor-type telescopic frame 10 then brings the traction net 11 out of the box 7 to intercept the out-of-control vehicle.

[0033] To prevent the scissor-lift telescopic frame 10 from being blocked by out-of-control vehicles when it extends, there are at least two scissor-lift telescopic frames 10 on a protective device. The scissor-lift telescopic frames 10 are evenly distributed along the length of the box body 7. One end of the towing net 11 is detachably connected to the end of the scissor-lift telescopic frame 10 away from the base 2. The other end of the towing net 11 is connected to the guardrail 1 through the box body 7 and the base 2 via a connector. The connector can be an anchor rod or a U-shaped clip. The upper surface of the towing net 11 is vertically mounted with nails 14. After the towing net 11 is pulled out of the box body 7 by the scissor-lift telescopic frame 10, the towing net 11 is laid flat on the ground. When an out-of-control vehicle passes by, the nails 14 are inserted into the tire and, as the tire rotates, the towing net 11 is wrapped around the tire, forcing the tire to stop rotating.

[0034] The scissor-type telescopic frame 10 is Y-shaped at one end near the base 2, consisting of a fixed rod 15 and a transmission rod 16. The fixed rod 15 is rotatably connected to the bottom of the housing 7 via a pin. The transmission rod 16 is fixedly connected to the moving block 12 via a connecting column 24. A stop bar 17 for blocking the scissor-type telescopic frame 10 is installed on the side of the scissor-type telescopic frame 10 where the fixed rod 15 is located. The transmission rod 16 moves toward the fixed rod 15 by moving the moving block 12 on the linear slide table 9, thereby causing the scissor-type telescopic frame 10 to extend and drive the traction net 11 out of the housing 7.

[0035] To further prevent the scissor lift telescopic frame 10 from being blocked by out-of-control vehicles when it extends, thus losing its interception effect, a controller 21 and a battery 22 electrically connected to the controller 21 are installed in the housing 7 of any protective device. The pressure sensor 5 and linear slide 9 in the protective device are both electrically connected to the controller 21. The controller 21 is configured to connect the pressure sensor 5 and linear slide 9 in multiple protective devices. The pressure sensor 5 and linear slide 9 are numbered in advance. After the pressure sensor 5 receives a pressure signal, it transmits it to the controller 21. The controller 21 issues an action command to the corresponding linear slide 9 and the surrounding linear slide 9 according to the pressure signal and number of the pressure sensor 5, so that the traction net 11 at the impact position and nearby extends completely, effectively intercepting the out-of-control vehicle when it passes by. This prevents the out-of-control vehicle from crashing through the guardrail 1 and leaving the bridge, and also prevents the out-of-control vehicle from being blocked and returning to the road, thus affecting other vehicles.

[0036] Example 2

[0037] like Figure 1 and Figure 3 As shown, in order to further optimize this application, as another optimized implementation of this application, in order to reduce the probability of stones splashed when a vehicle passes by puncturing the sealing film 8, an inclined baffle 18 is installed at the opening on the side of the box body 7 away from the base 2. The sealing film 8 is installed between the inclined baffle 18 and the bottom of the box body 7. The distance between the inclined baffle 18 and the bottom of the box body 7 is set according to the height of the scissor-type telescopic frame 10 and the towing net 11. By setting the inclined baffle 18, the area of ​​the sealing film 8 is reduced, thereby reducing the probability of the sealing film 8 being punctured by splashed stones.

[0038] To ensure that the towing net 11 has sufficient area to wrap around the tire, a rotating shaft 13 is installed inside the housing 7. The other end of the towing net 11 is fixedly connected to the rotating shaft 13 and wrapped around it. The rotating shaft 13 is located above the linear slide 9. The rotating shaft 13 accommodates the towing net 11, ensuring that the towing net 11 has sufficient area to wrap around the tire. The nails 14 are only installed vertically on the part of the towing net 11 above the scissor-type telescopic frame 10. This avoids unnecessary damage to the tire when the towing net 11 is wrapped around the tire, and also prevents the nails 14 from affecting the towing net 11's departure from the rotating shaft 13 when it is wrapped around the rotating shaft 13. To increase the fixing strength of the rotating shaft 13 and prevent it from being dragged away from the housing 7 by the towing net 11, in this application, both ends of the rotating shaft 13 are fixedly connected to the guardrail 1 through the housing 7 and the base 2 by anchor rods.

[0039] To facilitate the traction net 11 being carried away from the housing 7 by the scissor-type telescopic frame 10 and the traction net 11 leaving the scissor-type telescopic frame 10, a clamp 20 is installed at the end of the scissor-type telescopic frame 10 away from the base 2. The clamp 20 clamps the end of the traction net 11 away from the base 2. Under the action of the clamp 20, the traction net 11 is driven away from the scissor-type telescopic frame 10. After the nail 14 is inserted into the tire, the traction net 11 leaves the clamp 20 and wraps around the tire under the action of the tire, thus achieving braking.

[0040] Example 3

[0041] like Figure 1 As shown, in order to improve the battery life of this application and reduce manual intervention, a solar panel 23 connected to the battery 22 is installed on the upper end of the base 2. The battery 22 is extended by the setting of the solar panel 23, thus reducing manual intervention.

[0042] Based on the above, the working principle of this application is explained as follows: After the vehicle loses control and impacts the roller 4, the roller 4 moves towards the base 2 and applies pressure to the pressure sensor 5 after being impacted by the out-of-control vehicle. The pressure sensor 5 transmits the pressure signal to the controller 21 after receiving the pressure. The controller 21 issues action commands to the linear slide 9 at the impact position and the linear slide 9 around the impact position. The traction net 11 at the impact position and around the impact position is broken by the scissor-type telescopic frame 10 and extends out of the box 7. At this time, after the out-of-control vehicle impacts the roller 4, it rolls... Guided by cylinder 4, the vehicle moves along guardrail 1. During the movement, the tires of the out-of-control vehicle move to the upper surface of the towing net 11, and the nails 14 pierce into the tires. As the tires roll, the towing net 11 wraps around the tires, braking them. At the same time, since the other end of the towing net 11 is fixed to the guardrail 1 by a connector, after the towing net 11 wraps around the tires and tightens, the vehicle stops moving under the action of the towing net 11. The out-of-control vehicle is towed to the side of the guardrail 1 and stops moving, effectively preventing the out-of-control vehicle from crashing through the guardrail 1, leaving the bridge, and returning to the road, thus avoiding impacting other vehicles.

[0043] In summary, this application uses multiple protective devices installed sequentially along guardrail 1. The guiding mechanism in the protective device buffers and guides the out-of-control vehicle. The triggering mechanism is triggered by the guiding mechanism to issue an interception command to the traction mechanism. The traction mechanism intercepts the out-of-control vehicle that hits the guiding mechanism and fixes the out-of-control vehicle inside the guardrail 1, effectively solving the current problem of out-of-control vehicles crashing into the guardrail 1 and leaving the road.

[0044] It should be noted that in this application, the nails 14 are mainly distributed on the traction net 11 located on the scissor-type telescopic frame 10.
