Description

Technical Field

[0001] The present application relates to the technical field of bridges, and in particular to a bridge guardrail. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. Bridges generally consist of an upper structure, a lower structure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure for crossing obstacles.

When an out-of-control car on a bridge hits the guardrail, the guardrail is easily damaged and the vehicle is damaged. The guardrails lack the ability to buffer the impact force of the vehicle, which reduces the practicality of the guardrails. Utility Model Content

[0011] Furthermore, the card slot can be provided to cooperate with the sliding frame to adjust the position of the sliding frame, so as to facilitate the adjustment of the buffer position of the swing frame.

[0012] Through the above solution, two elastic steel plates are fixedly connected to the right side of the sliding frame, and the two elastic steel plates are symmetrical.

[0013] Furthermore, installing the elastic steel plate can buffer the impact force exerted on the multiple rubber buffer cylinders, thereby reducing the impact force transmitted to the sliding frame.

[0014] Through the above solution, the inner wall of the swing frame is rotatably connected with an anti-climbing rod, and the anti-climbing rod is treated to prevent rust.

[0017] Furthermore, installing the buffer spring can buffer the impact on the rubber buffer cylinder through the elastic deformation force of the buffer spring, thereby preliminarily reducing the impact force of the vehicle.

[0018] Through the above solution, each of the buffer components is arc-shaped, and both of the two elastic steel plates are arc-shaped.

[0019] Furthermore, installing the elastic steel plate can buffer the impact force exerted on the rubber buffer cylinder by the deformation force of the elastic steel plate, thereby preventing the swing frame from swinging violently.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The bridge guardrail can rotate after being impacted by installing a rubber buffer cylinder, thereby reducing the impact force brought by the vehicle and reducing the damage to the vehicle. The impact force can be buffered and absorbed through the cooperation of the buffer part and the buffer spring, avoiding the strong impact force from being transmitted to the swing frame and the vehicle to cause damage to both.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Buffer members 4 are slidably connected in the plurality of buffer grooves 3, and the bottom ends of the plurality of buffer members 4 are fixedly connected to fixing rods 5, and the bottom ends of the plurality of fixing rods 5 are hinged to the base 1. The outer surfaces of the plurality of fixing rods 5 are rotatably connected to rubber buffer cylinders 6, and the left ends of the plurality of buffer members 4 are fixedly connected to buffer springs 7, and the other ends of the plurality of buffer springs 7 are fixedly connected to the buffer grooves 3 adjacent to them. By installing the rubber buffer cylinder 6, it can rotate after being impacted, thereby reducing the impact force brought by the vehicle and reducing the damage to the vehicle. The cooperation of the buffer member 4 and the buffer spring 7 can buffer and absorb the impact force, thereby avoiding the strong impact force from being transmitted to the swing frame 2 and the vehicle to cause damage to both.

[0029] See also Figure 1 , Figure 2 and Figure 3The left side of the swing frame 2 is slidably connected with a sliding frame 8, and the upper surface of the base 1 is hinged with multiple damping cylinders 9 distributed at equal distances, and buffer rods 10 are slidably connected in the multiple damping cylinders 9. The upper ends of the multiple buffer rods 10 are hinged with the sliding frame 8. The cooperation of installing the buffer rods 10 and the damping cylinders 9 can buffer the swing force of the swing frame 2 and reduce the impact force received by the swing frame 2. The inner walls of the multiple damping cylinders 9 are fixedly connected with auxiliary springs 11, and the other ends of the multiple auxiliary springs 11 are fixedly connected to the buffer rods 10 close to them. The installation of the auxiliary springs 11 can absorb the impact force received by the buffer rods 10 and enable it to gradually reduce the impact force received by the swing frame 2. Two elastic steel plates 13 are fixedly connected to the right side of the sliding frame 8, and the two elastic steel plates 13 are symmetrical. The installation of the elastic steel plates 13 can buffer the impact force received by the multiple rubber buffer cylinders 6 and reduce the impact force transmitted to the sliding frame 8.

[0030] See also Figure 1 , Figure 2 and Figure 3 , the front and back sides of the swing frame 2 are provided with a plurality of slots 12 distributed at equal distances, and both ends of the sliding frame 8 are connected to the slots 12 close to them by bolts. The slots 12 can be adjusted with the cooperation of the sliding frame 8 to facilitate the adjustment of the buffer position of the swing frame 2. The inner wall of the swing frame 2 is rotatably connected with an anti-climbing rod 14, and the anti-climbing rod 14 is rust-proofed. Installing the anti-climbing rod 14 can prevent pedestrians from climbing the swing frame 2, so that pedestrians cannot be on the swing frame 2. Multiple buffer springs 7 are in a reset state, and multiple auxiliary springs 11 are in a reset state. Installing the buffer spring 7 can buffer the impact of the rubber buffer cylinder 6 through the elastic deformation force of the buffer spring 7, and preliminarily reduce the impact force of the vehicle.

Installing the elastic steel plate 13 can buffer the impact force of the rubber buffer cylinder 6 through the deformation force of the elastic steel plate 13, and can prevent the swing frame 2 from swinging violently.

[0031] A bridge guardrail in the present embodiment can rotate after being impacted by installing a rubber buffer cylinder, thereby reducing the impact force brought by the vehicle and reducing damage to the vehicle. The impact force can be buffered and absorbed through the cooperation of the buffer part and the buffer spring, avoiding the strong impact force from being transmitted to the swing frame and the vehicle to cause damage to both.

[0032] The working principle of the above embodiment is as follows: when a collision occurs between the vehicle and the rubber buffer cylinder 6, the rubber buffer cylinder 6 can rotate to avoid too much inertial impact force being transmitted to the multiple rubber buffer cylinders 6. At the same time, the multiple fixed rods 5 can swing in a circle, and the air in the buffer groove 3 can be squeezed by the buffer member 4, and the cooperation with the buffer spring 7 can buffer the impact force received by the rubber buffer cylinder 6, and the impact force can be further buffered by the cooperation of the elastic steel plate 13. When the impact force is transmitted to the swing frame 2, the swing frame 2 can swing and push the sliding rod to compress the air in the damping cylinder 9, so that the air can absorb the impact force after being squeezed, thereby avoiding the strong impact force being transmitted to the swing frame 2 and the vehicle to cause damage to both.
