AI Technical Summary
The existing bridge guardrail lacks a buffer structure, which causes the huge impact force during the vehicle to damage the people in the vehicle and may cause a second accident.
A railing device for bridge protection is designed, including a first frame, a guide column, a slider, a railing and a spring. By moving the slider on the guide column, an elastic force is generated to initially buffer the impact force, and the impact force is further reduced through the inclination and buffering mechanism of the first frame (such as a stop and a cylinder).
It effectively reduces the impact force during vehicle impact, prevents the vehicle from rushing out from above the railing, improves the safety of drivers, and reduces the probability of secondary accidents.

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to allow vehicles, pedestrians, etc. to pass smoothly. Guardrails are installed on both sides of the bridge to prevent out-of-control vehicles from going over the bridge.
[0003] Most existing bridge guardrails do not have a buffer structure. When a vehicle hits the guardrail, there will be a large impact force. If the brakes are applied immediately, the huge impact force will cause harm to the people in the car, and if the vehicle rushes out from above the guardrail, a secondary accident will occur. Therefore, the present application proposes a bridge guardrail device. Summary of the invention
[0004] The utility model aims to solve the problems existing in the background technology and to provide a bridge protection railing device which has good buffering effect and can prevent wheels from rushing out of the guardrail.

[0006] Optionally, the buffer mechanism includes a second frame body hinged on one side of the first frame body, slots are provided on both sides of the bottom of the second frame body, a plurality of equidistantly arranged blocks are fixedly installed on both sides of the inner wall of the slot, the thickness of the blocks gradually increases, a column is slidably installed on one side of the slot, one end of the column is located in the slot and contacts the block, and the other end of the column is arc-shaped and contacts the first frame body.
[0007] Optionally, a support plate is fixedly mounted on one side of the top of the second frame body, a fixing frame is fixedly mounted on one side of the support plate, and the fixing frame is arranged to be inclined.
[0008] Optionally, a plurality of pairs of mounting blocks arranged at equal distances are fixedly mounted on one side of the top of the first frame body, short rods are rotatably mounted between the mounting blocks, and the short rods are fixedly connected to the second frame body.
[0009] Optionally, bumps are fixedly mounted on both sides of the column, guide grooves are provided on both sides of the notch, and the bumps are located in the guide grooves.
[0010] Optionally, a plurality of threaded holes are formed at the bottom of the second frame and the fixing frame, and screws are installed in the threads of the threaded holes.
[0011] Optionally, the thickness of the first frame is 4-5CM, and the thickness of the second frame is 3-5CM.
[0012] Compared with the prior art, the utility model has the following beneficial technical effects:
[0013] The utility model uses a vehicle to hit the railing on the first frame, and the railing drives the slider to move on the guide column. When the slider squeezes the spring, elastic force is generated and acts on the slider. The impact force of the vehicle on the railing is reduced, and preliminary buffering of the impact force is achieved.
[0014] Furthermore, the vehicle hits the first frame, causing the first frame to tilt and confining the vehicle below the first frame. As the first frame tilts, the first frame drives the column to contact the block. As the column moves, the resistance of the block to the column gradually increases, thereby preventing the vehicle from driving out from above the railing and buffering the impact force again.
