Description

Technical Field

[0001] The present application relates to a crash barrier for a bridge. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. With people and vehicles passing on bridges, it is easy for accidents to cause collisions and rollovers. In order to increase safety, guardrails are generally installed on both sides of the bridge.

[0003] Although common guardrails have anti-collision properties, they cannot disperse the impact force after being hit, which will increase the degree of damage to the guardrails and thus increase maintenance costs. Moreover, guardrails are generally set on both sides of the bridge. Passersby like to lie on the guardrails to rest or watch the scenery in the distance of the bridge. There is no blocking structure on the top of the guardrail, and mobile phones or other items held by pedestrians are easy to fall.

[0004] Therefore, it is desired to provide a crash barrier for a bridge. Utility Model Content

[0005] In this embodiment, a crash barrier for a bridge is provided to solve the problem that after the guardrail is hit, the impact force of the collision cannot be dispersed, which increases the damage to the guardrail and thus increases the maintenance cost; and the problem that passers-by like to lie on the guardrail to rest or watch the scenery in the distance of the bridge, and mobile phones or other items in their hands are easily dropped.

[0006] According to one aspect of the present application, a bridge crash barrier is provided, comprising a top plate, vertical rods are fixed on both sides of the bottom of the top plate, a fixing plate 1 is fixed to the bottom end of the vertical rod through the bottom plate, the vertical rod is fixedly connected to the bottom plate, and a plurality of fixing holes are arranged on the fixing plate 1, characterized in that the bridge crash barrier also includes:

[0007] An anti-collision plate, the anti-collision plate is arranged on one side of the vertical rod;

[0008] A buffer structure, wherein the buffer structure is arranged between the anti-collision plate and the vertical rod, and the buffer structure is connected to the anti-collision plate and the vertical rod;

[0009] The baffle is fixed at one end of the top of the top plate, and the baffle is arranged in an arc shape.

[0010] Specifically, multiple groups of cross bars are provided at the bottom of the top plate, and the two ends of the cross bars are fixed to the side walls of the vertical bars corresponding to the two sides of the bottom of the top plate. Blocks are fixed at one end of the top plate and the bottom plate, and the other ends of the top plate and the bottom plate corresponding to the blocks are provided with slots, and the blocks and the slots are provided with mounting holes correspondingly.

[0011] Specifically, the anti-collision plate is arranged in a U shape, and the anti-collision plate is arranged outside the vertical rod. The buffer structure between the anti-collision plate and the vertical rod includes a spring shock absorber, a second fixed plate, a first fixed block, a connecting rod, a second fixed block, a sliding rod, a support rod, a support plate, a limit rod and a spring.

[0012] Specifically, one end of the spring shock absorber is fixed at the middle position of the inner wall of the anti-collision plate, and the other end of the spring shock absorber is fixed with a fixing plate 2, the top and bottom of the fixing plate 2 are fixed with sliding rods, and the outside of the sliding rod is slidably connected with a fixing block 2.

[0013] Specifically, a fixing block 1 is symmetrically fixed to the side walls of the anti-collision plate on both sides of the spring shock absorber, and both ends of the fixing block 1 are rotatably connected to connecting rods, and the other end of the connecting rod is rotatably connected to the corresponding two ends of the fixing block 2, and the connecting rods on both sides of the spring shock absorber are symmetrically and tilted.

[0014] Specifically, the bottom of the top plate and the top of the bottom plate are fixed with a limit rod and a spring corresponding to the sliding rod, the spring is sleeved on the outside of the limit rod, and the other ends of the limit rod and the spring are fixed with a stop plate.

[0015] Specifically, abutment rods are fixed on both sides of one end of the second fixing block away from the second fixing plate, and the abutment rods abut against the corresponding abutment plates.

[0016] The benefits of this application are:

[0017] 1. By arranging a limit rod 1 and a spring 1 on both sides of the fixed plate 2, the limit rod 1 and the spring 1 are in contact with the fixed block 2, and the fixed block 2 is connected to the fixed block 1 through a connecting rod. When the anti-collision plate is hit, the anti-collision plate will move to the side of the vertical rod, and the spring shock absorber will play a buffering and anti-collision effect, absorbing and reducing vibration. At this time, the inclination angle of the connecting rod will be increased, so that the fixed block 2 will squeeze the spring. The spring has a mobile buffering function, which can disperse a part of the impact force of the impact on the anti-collision plate, reduce the impact on the overall guardrail, thereby reducing the damage to the guardrail and reducing the maintenance cost.

[0018] 2. By fixing a baffle at one end of the top plate, the baffle is set in an arc shape. When pedestrians lie on the guardrail and put their hands on the top plate, the baffle can shield their hands to prevent mobile phones or other items in their hands from falling under the bridge, thereby improving the practicality of the anti-collision barrier.
