Description

Technical Field

[0001] The utility model belongs to the technical field of highway guardrails, and in particular relates to a movable guardrail for an expressway. Background Art

[0002] Movable guardrail is a type of guardrail that is installed at the opening of the central dividing strip of the highway to facilitate some vehicles and emergency use.

[0003] The Chinese patent with application number CN202210879070.3 in the prior art discloses a highway movable guardrail that is easy to disassemble and assemble, belonging to the technical field of highway ancillary equipment. It includes a protection component and a connection component. The protection component includes a first protection plate and a second protection plate. The length direction of the first protection plate is parallel to that of the second protection plate. A protection rod is provided at the end of the first protection plate. The end of the protection rod away from the first protection plate is connected to the second protection plate. The cross section of the movable guardrail perpendicular to the moving direction is a trapezoid. The connection component is used to connect the protection component with the standard section guardrail. When the movable guardrail is disassembled and assembled, the protection plates on both sides and the fixed rods at the ends can be smoothly separated from the adjacent standard section guardrails. Since the cross section is a trapezoid, the inclination of the fixed rods when the movable guardrail moves can make room for it, reducing the possibility of collision between the movable guardrail and the standard section guardrail and reducing the deformation of the movable guardrail; the connection component realizes the connection between the two, improves the convenience of disassembly and assembly of the movable guardrail, and thus improves the operating efficiency of the disassembly and assembly process.

[0004] In order to facilitate disassembly, the existing movable guardrail is designed to be composed of several small structures. However, this structure reduces the anti-buffering performance and has limited ability to cope with sudden unexpected situations. For this reason, we propose a movable guardrail for highways.

[0026] A movable guardrail for a highway comprises a base plate 1 and a pedestal 2. A straight rod 3 is fixedly connected to one side of the base plate 1 close to the pedestal 2. A vertical plate 6 is fixedly connected to the top of the pedestal 2. Positioning plates 7 are arranged on the vertical plate 6 close to the straight rod 3. The ends of the straight rods 3 slide through the positioning plates 7. A spring 5 is sleeved on the surface of the straight rods 3. A baffle 11 is arranged between adjacent base plates 1.

The surface is painted for rust prevention to enhance its durability. The base 2 is fixed to the road ground by bolts. There is a certain distance between the base plate 1 and the vertical plate 6. The straight rod 3 and the spring 5 are both located between the base plate 1 and the vertical plate 6. When the base plate 1 is hit, the base plate 1 moves toward the base 2. Under the elastic action of the spring 5, the impact force can be greatly reduced, thereby reducing damage and slowing down the linear impact on the vehicle to protect the lives of passengers. In this scheme, adjacent base plates 1 are connected by baffles 11, and the baffles 11 pass through the slide groove 10 to play the role of guardrails. The baffles 11 can be removed as needed, and when the baffles 11 are hit, the spring 5 also plays a buffering role. The structure is simple and easy to install. The surface of the preferred base plate 1 is sprayed with reflective strips 12 to alert passing vehicles.

[0028] Specifically, slide grooves 10 are provided on both sides of the base plate 1 , and the baffles 11 are movably inserted into the slide grooves 10 .
