Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically relating to a prefabricated highway guardrail. Background Technology

[0002] Highways are usually equipped with guardrails to prevent vehicles from running off the road and causing serious damage. The guardrails are mainly made by fixing wavy horizontal rails with horizontal corrugations to posts. In order to better warn drivers, reflectors can also be installed on the protruding parts of the horizontal corrugations of the guardrails.

[0003] A prior art patent, CN220433497U, describes a highway guardrail. This patent includes posts and horizontal rails, with a spring between the posts and rails. The cross-section of the rails is Ω-shaped. Fastening bolts connect the horizontal rails, springs, and posts. A spring is installed between the spring and the post, movably fitted onto the surface of the fastening bolts. When the horizontal rail is struck by a vehicle, the impact force is transmitted through the horizontal rail to the spring. The compressed spring deforms from its center towards the post, further compressing the spring and thus weakening the impact force of the horizontal rail on the post surface. This minimizes damage to the post and provides good cushioning and impact resistance. However, in practical use, this patent has the following shortcomings: Firstly, it is inconvenient to quickly and easily install and disassemble the guardrail, resulting in low installation efficiency. Secondly, it is inconvenient to replace individual sections of the guardrail during maintenance, further reducing its practicality.

[0004] Therefore, there is a need for a prefabricated highway guardrail to solve the problems of inconvenience in the quick and easy installation and disassembly of guardrails and inconvenience in the individual replacement and maintenance of guardrails in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated highway guardrail to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated highway guardrail, comprising a base, mounting bolts, and a fixing seat. The fixing seat is fixedly installed on the top of the base, and the mounting bolts are disposed on the base for positioning and installation. The fixing seat is provided with a positioning mechanism, and an installation post is detachably installed on the fixing seat through the positioning mechanism. A guardrail mechanism is provided on the installation post, and a fixing mechanism is provided on the upper part of the installation post. The guardrail mechanism is detachably connected to the installation post through the fixing mechanism.

[0007] It should be noted in the solution that the positioning mechanism includes a positioning block, which is matched and fixed inside the fixing seat. The top of the positioning block is fixedly connected to the bottom of the mounting column. Positioning grooves are symmetrically opened on the left and right sides of the positioning block. Limiting blocks are set in the positioning grooves. A pulling block is fixedly connected to one side of the limiting block. An installation frame is fixedly installed on the outer surface of the fixing seat on the outer side of the pulling block. A spring is fixedly installed between the limiting blocks in the installation frame.

[0008] It is worth noting that the limiting block is installed by sliding the pulling block through the fixed base.

[0009] It should be further noted that the pull block is slidably installed outside the mounting frame.

[0010] In a preferred embodiment, two springs are provided on the limiting block, and the two springs are symmetrically arranged on the front and rear sides of the pulling block.

[0011] In a preferred embodiment, the guardrail mechanism includes a limiting groove, which is formed on the surface of the mounting post. A fixing rod is provided in the limiting groove and is fixedly installed on the mounting post. A connecting block is slidably installed in the limiting groove through the fixing rod, and a guardrail is fixedly connected to one side of the connecting block.

[0012] In a preferred embodiment, two limiting grooves are provided on the mounting column, and the two limiting grooves are symmetrically arranged on the front and rear side surfaces of the mounting column.

[0013] In a preferred embodiment, the fixing mechanism includes a fixing plate disposed on the top of the mounting column. A connecting bolt is installed on the fixing plate, and a threaded groove matching the connecting bolt is opened on the top of the fixing rod. The fixing plate is fixedly connected to the top of the mounting column by the connecting bolt and the threaded groove.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a prefabricated highway guardrail, including a base 1, mounting bolts 2 and a fixing seat 3. The fixing seat 3 is fixedly installed on the top of the base 1. The mounting bolts 2 are provided on the base 1 for positioning and installation. The fixing seat 3 is provided with a positioning mechanism 4. The fixing seat 3 is detachably installed with a mounting post 5 through the positioning mechanism 4. The mounting post 5 is provided with a guardrail mechanism 6. The upper part of the mounting post 5 is provided with a fixing mechanism 7. The guardrail mechanism 6 is detachably connected to the mounting post 5 through the fixing mechanism 7.

[0024] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the positioning mechanism 4 includes a positioning block 401, which is matched and located inside the fixing seat 3. The top of the positioning block 401 is fixedly connected to the bottom of the mounting column 5. Positioning grooves 402 are symmetrically opened on the left and right sides of the positioning block 401. Limiting blocks 403 are set in the positioning grooves 402. A pulling block 404 is fixedly connected to one side of the limiting block 403. The limiting block 403 slides through the fixing seat 3 via the pulling block 404. An mounting frame 405 is fixedly installed on the outer surface of the fixing seat 3 on the outer side of the pulling block 404. The pulling block 404 slides through the outside of the mounting frame 405. A spring 406 is fixedly installed between the limiting blocks 403 inside the mounting frame 405. Two springs 406 are set on the limiting blocks 403, and the two springs 406 are symmetrically arranged on the front and rear sides of the pulling block 404.

[0025] In use, by pulling the pull blocks 404 on both sides, the limiting block 403 slides within the fixed base 3 and the mounting frame 405, making it easier to insert the mounting post 5 into the fixed base 3 via the positioning block 401. At this time, under the elastic force of the spring 406, the limiting block 403 can position the positioning block 401 within the positioning groove 402, thereby allowing the mounting post 5 to be installed on the upper part of the fixed base 3, facilitating the disassembly and assembly of the device and improving its ease of operation.

[0026] As can be seen from the above working process, the positioning mechanism 4 facilitates quick and convenient assembly and disassembly of the device on the base 1, thereby improving the installation efficiency and ease of installation. Furthermore, its operation is simple and easy to implement.

[0027] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the guardrail mechanism 6 includes a limiting groove 601, which is formed on the surface of the mounting post 5. There are two limiting grooves 601 on the mounting post 5, and the two limiting grooves 601 are symmetrically arranged on the front and rear surfaces of the mounting post 5. A fixing rod 603 is provided in the limiting groove 601 and is fixedly installed on the mounting post 5. A connecting block 602 is slidably installed in the limiting groove 601 through the fixing rod 603. A guardrail 604 is fixedly connected to one side of the connecting block 602.

[0028] In use, the guardrail 604 is slidable on the fixing rod 603 via the connecting block 602 and within the limiting groove 601, so that the guardrail 604 is installed on the mounting post 5. The guardrail 604 provides road edge protection. With the setting of the fixing rod 603, when the guardrail 604 is subjected to a large impact force, the guardrail 604 will act on the fixing rod 603 through the connecting block 602. When the rigidity of the fixing rod 603 is exceeded, the fixing rod 603 will break on the mounting post 5. Thus, the guardrail 604 can mitigate the impact force and prevent the vehicle from being subjected to a large force, causing more serious damage.

[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the fixing mechanism 7 includes a fixing plate 701, which is located on the top of the mounting column 5. A connecting bolt 702 is installed on the fixing plate 701. The connecting bolt 702 has a matching threaded groove 703 at the top of the fixing rod 603. The fixing plate 701 is fixedly connected to the top of the mounting column 5 by the connecting bolt 702 and the threaded groove 703.

[0030] In use, the connecting bolts 702 are aligned with the threaded grooves 703 to form a threaded connection, thereby fixing the fixing plate 701 to the upper part of the mounting post 5, thus improving the stability of the guardrail 604 after installation.

[0031] This solution has the following working process: When this device is in use, the base 1 is positioned and installed using the mounting bolts 2. By pulling the pull blocks 404 on both sides, the limiting block 403 slides within the fixed base 3 and the mounting frame 405, facilitating the insertion of the mounting post 5 into the fixed base 3 via the positioning block 401. At this time, under the elastic force of the spring 406, the limiting block 403 can position the positioning block 401 within the positioning groove 402, thus allowing the mounting post 5 to be installed on the upper part of the fixed base 3. Then, the guardrail 604 slides on the fixed rod 603 via the connecting block 602 and within the limiting groove 601, allowing the guardrail 604 to be installed on the mounting post 5. The guardrail 604 provides road edge protection. By installing the fixing plate 701 on the upper part of the mounting post 5, and then connecting the bolt 702 to the threaded groove 703, the fixing plate 701 is fixedly installed on the upper part of the mounting post 5, thereby improving the stability of the guardrail 604 after installation. Furthermore, due to the setting of the fixing rod 603, when the guardrail 604 is subjected to a large impact force, the guardrail 604 will act on the fixing rod 603 through the connecting block 602. When the rigidity of the fixing rod 603 is exceeded, the fixing rod 603 will break at the mounting post 5. Thus, the guardrail 604 can mitigate the impact force and prevent the vehicle from being subjected to a large force, causing more serious damage.

[0032] In summary: The positioning mechanism 4 facilitates quick and easy assembly and disassembly of the device on the base 1, thereby improving the installation efficiency and convenience of the device. Furthermore, its operation is simple and easy to implement. The guardrail mechanism 6, in conjunction with the fixing mechanism 7, facilitates the individual disassembly and installation of the guardrail 604. This improves the convenience of maintenance and replacement when replacing damaged guardrails 604, thus enhancing the practicality of the device.
