Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and specifically to a safety guardrail, which is easy to maintain. Background Technology

[0002] Highway maintenance refers to the upkeep and maintenance of highways. Upkeep focuses on the entire process from the time a highway is built and opened to traffic, while maintenance focuses on repairing damaged sections. Highway maintenance is the work carried out to keep highways in good condition, prevent a decline in their quality of use, and provide good service to highway users.

[0003] Safety barriers are used to protect vehicles and occupants from collisions with natural or man-made objects located beside the road. A vehicle impacting a traffic barrier can damage both the vehicle / passengers and the barrier itself. Existing highway barriers are mostly composed of posts, corrugated steel guardrail panels, and hexagonal anti-collision blocks. These structures are typically installed using bolts and nuts, making installation and disassembly time-consuming and labor-intensive. Furthermore, upon external impact, the hexagonal anti-collision blocks may alter their structure and not automatically reset, requiring repair and replacement by highway maintenance companies. This significantly increases the workload and cost of highway maintenance. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a highway safety guardrail that is easy to maintain, convenient to disassemble and use, and reduces the difficulty of later maintenance work.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A highway safety guardrail that is easy to maintain consists of several guardrail units connected and arranged sequentially along the highway. Each guardrail unit includes two opposing positioning posts and a guardrail panel that can be detachably installed between the two positioning posts. The positioning posts are fixedly installed on the foundation on both sides of the highway. Both ends of the guardrail panel are elastically connected to the positioning posts through elastic mounting components, so that when the guardrail panel is impacted by an external force, the elastic mounting components between the guardrail panel and the positioning posts undergo elastic deformation to create a buffer distance between the guardrail panel and the positioning posts.

[0007] Furthermore, the flexible installation assembly includes a connecting rod detachably connected to the positioning post, and a limiting baffle, a clamping baffle, and a spring sequentially installed on the connecting rod. One end of the connecting rod is fixedly connected to the guardrail baffle, and the other end is fixedly connected to the limiting baffle. The clamping baffle is slidably connected to the connecting rod to slide along the axial direction of the connecting rod, and the spring is installed between the clamping baffle and the guardrail baffle.

[0008] Furthermore, a through hole is provided in the middle of the clamping baffle to cooperate with the connecting rod, and the connecting rod is inserted into the through hole and slidably connected with the clamping baffle.

[0009] Furthermore, the top of the positioning support column is provided with an installation groove that mates with the connecting rod, and the connecting rod is inserted into the installation groove and detachably connected to the positioning support column.

[0010] Furthermore, the two sides of the positioning column cooperate with the limiting baffle and the clamping baffle respectively, so that when the connecting rod is inserted into the mounting groove, the limiting baffle and the clamping baffle are in close contact with the two sides of the positioning column respectively.

[0011] Furthermore, the positioning support has a base plate at its bottom, and mounting holes are provided at the four corners of the base plate. The positioning support is fixed to the ground through the mounting holes on the base plate and bolts.

[0012] Furthermore, a reinforcing rib is fixedly connected between the bottom of the positioning column and the base plate.

[0013] The beneficial effects of this utility model are as follows: The highway safety guardrail provided by this utility model is fixedly installed on the foundation on both sides of the highway by setting positioning posts. Both ends of the guardrail panel are clamped to the positioning posts by the elastic force of the elastic installation components and are detachably connected to the positioning posts. The installation and disassembly are convenient, saving a lot of installation and construction time and labor. It greatly facilitates the disassembly and repair work in the later highway maintenance process and improves the efficiency of the later highway maintenance. When the guardrail panel is hit by a vehicle, the deformation buffer of the elastic installation components reduces the impact of the vehicle impact on the guardrail panel and the positioning posts. After the impact accident is eliminated, the reset function of the elastic installation components restores the guardrail panel to its original state, which greatly reduces the workload of the later highway maintenance and ensures safety.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, this utility model provides a highway safety guardrail that is easy to maintain. It consists of several guardrail units connected and arranged sequentially along the highway direction. Each guardrail unit includes two opposing positioning posts 21 and a guardrail baffle 11 that is detachably installed between the two positioning posts 21. The positioning posts 21 are fixedly installed on the foundation on both sides of the highway. Both ends of the guardrail baffle 11 are elastically connected to the positioning posts 21 through elastic mounting components, so that when the guardrail baffle 11 is impacted by an external force, the elastic mounting components between the guardrail baffle 11 and the positioning posts 21 undergo elastic deformation to generate a buffer distance between the guardrail baffle 11 and the positioning posts 21.

[0021] like Figure 3-4 As shown, the elastic mounting assembly includes a connecting rod 12 detachably connected to the positioning post 21, and a limiting baffle 13, a clamping baffle 14, and a spring 15 sequentially mounted on the connecting rod 12. One end of the connecting rod 12 is fixedly connected to the guardrail baffle 11, and the other end is fixedly connected to the limiting baffle 13. The clamping baffle 14 is slidably connected to the connecting rod 12 to slide along the axial direction of the connecting rod 12. The spring 15 is installed between the clamping baffle 14 and the guardrail baffle 11. A through hole is provided in the middle of the clamping baffle 14 to cooperate with the connecting rod 12. The connecting rod 12 is inserted into the through hole and slidably connected to the clamping baffle 14. When the guardrail panel 11 is impacted by an external force, the guardrail panel 11 compresses the spring 15 towards the clamping panel 14. Through the buffering effect of the spring 15, the impact of the external impact on the guardrail panel 11 and the positioning post 21 is reduced, thereby reducing the damage to the guardrail panel 11 and the positioning post 21 and greatly reducing the workload of subsequent highway maintenance. After the impact accident is eliminated, the guardrail panel 11 is restored to its original position through the reset function of the spring 15.

[0022] like Figure 5As shown, the top of the positioning support 21 has a mounting groove 22 that mates with the connecting rod 12. The connecting rod 12 is inserted into the mounting groove 22 and detachably connected to the positioning support 21. The two sides of the positioning support 21 respectively mate with the limiting baffle 13 and the clamping baffle 14, so that when the connecting rod 12 is inserted into the mounting groove 22, the limiting baffle 13 and the clamping baffle 14 are in close contact with the two sides of the positioning support 21. Specifically, the positioning post 21 is an elliptical post, and both the limiting baffle 13 and the clamping baffle 14 are arc-shaped baffles adapted to the elliptical post. The size of the clamping baffle 14 is larger than that of the limiting baffle 13. Through the tightening of the spring 15, the inner arc surface of the arc-shaped clamping baffle 14 is pressed against the outer arc surface on one side of the elliptical positioning post 21, and the outer arc surface on the other side of the elliptical positioning post 21 is pressed against the inner arc surface of the arc-shaped limiting baffle 13. Thus, the limiting baffle 13 and the clamping baffle 14 clamp the positioning post 21 to insert and fix the guardrail baffle 11 onto the positioning post 21. The installation and disassembly are convenient, which greatly facilitates the disassembly and repair work in the later highway maintenance process and improves the efficiency of the later highway maintenance.

[0023] The positioning support 21 has a base plate 23 at its bottom, and mounting holes 24 are provided at each of the four corners of the base plate 23. The positioning support 21 is fixedly installed on the foundation on both sides of the highway through the mounting holes 24 on the base plate 23 and bolts. A reinforcing rib plate 25 is fixedly connected between the bottom of the positioning support 21 and the base plate 23.

[0024] In use, this utility model firstly involves installing and fixing multiple positioning posts 21 sequentially onto the foundation on both sides of the highway via mounting holes 24 on their base plates 23 and bolts. Then, the clamping baffles 14 at both ends of the guardrail baffle 11 are pushed to compress the springs 15, inserting the connecting rod 12 between the limiting baffle 13 and the clamping baffle 14 into the mounting groove 22 of the positioning post 21. The clamping baffle 14 is then released, causing it to clamp the positioning post 21 towards the limiting baffle 13 under the force of the spring 15. The guardrail baffle 11 is then fixed between the two positioning posts 21. This method facilitates installation and disassembly, saving significant installation time and labor, and greatly facilitating subsequent highway construction. The disassembly and repair work during road maintenance improves the efficiency of subsequent highway maintenance. When the guardrail panel 11 is impacted by an external force, the guardrail panel 11 compresses the spring 15 on the clamping side of the panel 14. Through the buffering effect of the spring 15, the impact of the external impact on the guardrail panel 11 and the positioning post 21 is reduced. After the impact accident is eliminated, the guardrail panel 11 is restored to its original position through the reset function of the spring 15. In this way, the energy of the collision is absorbed in time when it is hit by a vehicle, reducing the damage to the guardrail panel 11 and the positioning post 21, making them less likely to be destroyed. This greatly reduces the workload of subsequent highway maintenance, ensures safety, and does not affect subsequent reset use and aesthetics.

[0025] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
