Description

Technical Field

[0001] This utility model relates to the technical field of highway traffic safety facilities, specifically to a column cap structure for roadbed beam-column guardrails. Background Technology

[0002] Roadbed beam-post guardrails are a common highway traffic safety facility, typically installed along the edge of the roadbed. Due to their advantages such as a wide safety protection range, low wind resistance coefficient, and low steel consumption, they are particularly effective in mitigating snow accumulation on wind-blown snow sections and have been widely adopted. Roadbed beam-post guardrails mainly consist of crossbeams, posts, brackets, and anti-blocking blocks, etc. (See attached diagram). Figure 1 The posts are connected together by guardrail bolts that pass through pre-drilled holes in the posts, along with anti-blocking blocks and crossbeams, thus completing the guardrail installation. The top of the post is open. To seal the top of the post and prevent water, dust, and other foreign objects from entering, and to avoid internal corrosion and frost heave, a post cap needs to be installed at the top of the post. Traditional post caps have mounting holes through which the guardrail bolts pass to fix the post cap to the top of the post. When removing the post cap, the guardrail bolts usually need to be removed. At this time, the crossbeam and the post are separated. After the post cap is installed, the crossbeam needs to be repositioned and reinstalled.

[0003] Existing column caps are complex to install and dismantle, require a large amount of maintenance and replacement work, have low installation efficiency, and have limited functionality, making them difficult to meet the needs of modern transportation facilities. This solution addresses this technical problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a column cap structure for roadbed beam-column guardrails. Through the design of the rear-mounted hook assembly, the column cap is installed separately after the main guardrail structure is installed, which simplifies the construction process, reduces the installation difficulty, and improves the installation and maintenance efficiency. The lower column cap connects the upper column cap to the guardrail post, resulting in a stable structure that effectively protects the end of the post. The pre-reserved connection port at the top of the column cap provides convenient installation conditions for additional intelligent transportation facilities, meeting the needs of modern transportation facilities.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a post cap structure for roadbed beam-column guardrail, comprising a rear hook assembly, a lower post cap, and an upper post cap;

[0006] The guardrail post has a pre-drilled hole on its side, through which a guardrail bolt is installed to connect with the crossbeam. The rear hook assembly is used to attach to the installed guardrail bolt.

[0007] The bottom side of the lower post cap contacts the top of the guardrail post, and the lower post cap is connected to the rear hook assembly;

[0008] A locking mechanism is provided between the top side of the lower column cap and the bottom side of the upper column cap. The lower column cap and the upper column cap are detachably connected through the locking mechanism. The top side of the upper column cap is provided with a connection port for installing intelligent transportation facilities.

Detailed Implementation

[0026] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] See Figures 1-6 A column cap structure for roadbed beam-column guardrail, comprising a rear hook assembly 100, a lower column cap 200, and an upper column cap 300;

[0028] The guardrail post 400 has a reserved hole 402 on its side through which a guardrail bolt 401 is connected to the crossbeam. The rear hook assembly 100 is used to hang on the installed guardrail bolt 401.

[0029] The bottom side of the lower post cap 200 contacts the top of the guardrail post 400, and the lower post cap 200 is connected to the rear hook assembly 100;

[0030] A locking mechanism is provided between the top side of the lower column cap 200 and the bottom side of the upper column cap 300. The lower column cap 200 and the upper column cap 300 are detachably connected through the locking mechanism. The top side of the upper column cap 300 is provided with a connection port 304 for installing intelligent transportation facilities.

[0031] The rear hook assembly 100 includes a connecting plate 101 and a plurality of hooks 104 arranged in an array on the side of the connecting plate 101. The hooks 104 are open and facing upward. The hooks 104 are hooked to the side of the guardrail bolt 401. The end of the connecting plate 101 is provided with a connecting bolt 102. The connecting bolt 102 passes through the lower post cap 200 and is connected by a fastening nut 103.

[0032] The engaging mechanism includes a connecting sleeve 201 fixedly disposed on the top side of the lower post cap 200 and several pins 302 fixedly disposed on the bottom side of the upper post cap 300. The side of the connecting sleeve 201 is provided with several engaging grooves 2011 corresponding to the pins 302. The pins 302 can be engaged with the engaging grooves 2011 in a separable manner. The bottom side of the lower post cap 200 is provided with a lower cap edge 202. The inner diameter of the lower cap edge 202 is larger than the outer diameter of the guardrail post 400 so that the lower post cap 200 can move horizontally along the guardrail post 400.

[0033] The inner side of the snap-fit ​​groove 2011 is provided with a stop 2012 to prevent the pin 302 from falling out. A compression spring 303 is provided between the upper cap 300 and the lower cap 200. One end of the compression spring 303 is located in the connecting sleeve 201, and the other end of the compression spring 303 is connected to the upper cap 300.

[0034] The upper cap 300 includes a cap top 301 and an upper cap brim 305. A pin 302 is located on the inner side of the upper cap brim 305, and a connecting port 304 is located on the upper cap brim 305.

[0035] The 304 connector is a standardized interface used for installing intelligent transportation facilities, such as the 500 solar-powered visual guidance light.

[0036] There are three hooks 104, and all three hooks 104 are welded to the connecting plate 101.

[0037] The specific working process of this utility model:

[0038] First, install the rear hook assembly. Insert the end of the connecting bolt 102 of the rear hook assembly 100 into the lower post cap 200 and temporarily fix it with the fastening nut 103. Holding the lower post cap 200, lower the rear hook assembly 100 into the guardrail post 400, aligning it with the guardrail bolt 401. At this time, the three hooks 104 will be facing upwards. Hold the lower post cap 200 and approach it horizontally from the side of the guardrail bolt 401. Position the hooks 104 through the guardrail bolt 401 and hook the three hooks 104 onto the thread of the guardrail bolt 401 respectively.

[0039] Tighten the fastening nut 103 to raise the connecting bolt 102. The connecting bolt 102 raises the hook 104 through the connecting plate 101. The hook 104 will be firmly locked by the downward force and will not come out on its own. After the rear hook assembly 100 is fastened and installed, the "rear" design of the hook 104 means that the hook 104 is installed after the guardrail is installed, without the need to remove the guardrail bolt 401.

[0040] Then install the solar-powered line-of-sight light 500. The solar-powered line-of-sight light 500 is installed on the connection port 304 of the upper column cap 300 through its standard base. Since the connection port 304 is a standardized interface, the installation process of the solar-powered line-of-sight light 500 is quick and easy.

[0041] Then, place the compression spring 303 inside the connecting sleeve 201 of the lower column cap 200, hold the upper column cap 300 with the installed equipment in hand, and press down the compression spring 303 so that the pins 302 at the bottom of the upper column cap 300 are precisely aligned with the snap-fit ​​groove 2011 on the side of the connecting sleeve 201 at the top of the lower column cap 200.

[0042] Press the upper cap 300 vertically downwards. At this time, the compression spring 303 inside the connecting sleeve 201 will be compressed. After pressing it into place, rotate the upper cap 300 clockwise (usually a small angle is enough, such as 15-30 degrees) so that the pin 302 slides into the stop 2012 inside the snap-fit ​​groove 2011.

[0043] Releasing the hand causes the spring 303 to rebound, causing the upper cap 300 to slightly rise, thus pressing the pin 302 firmly against the stop 2012, creating a self-locking mechanism and completing the locking process. At this point, the upper cap 300 and the lower cap 200 are securely connected and cannot be pulled out directly. The upper cap edge 305 and the lower cap edge 202 together form the complete appearance of the cap.

[0044] When maintenance, replacement, or upgrades of intelligent transportation facilities are required, the design of this structure makes disassembly extremely convenient:

[0045] To remove the upper cap 300: Hold the upper cap 300 in your hand and rotate it counterclockwise by a small angle to overcome the slight pressure of the compression spring 303, so that the pin 302 is released from the stop 2012. After aligning it with the entrance of the snap-fit ​​slot 2011, the upper cap 300 and the smart device on it can be removed vertically upwards.

[0046] Equipment maintenance: On-the-ground maintenance, replacement, or data collection of removed equipment.

[0047] Reinstall: After maintenance is complete, repeat the steps in step 3 above to quickly reinstall.

[0048] To remove the entire post cap: If you need to completely remove the post cap, simply use a wrench to loosen the fastening nut 103, separate the lower post cap 200 from the rear hook assembly 100, and then directly remove the hook 104 horizontally from the guardrail bolt 401 without any damage to the original guardrail.

[0049] The design of the rear hook assembly 100 allows for separate installation of the post cap after the main structure of the guardrail is installed, simplifying the construction process, reducing installation difficulty, and improving installation and maintenance efficiency. The lower post cap 200 connects the upper post cap 300 to the guardrail post 400, ensuring structural stability, effectively protecting the end of the post, and extending the service life of the guardrail.

[0050] The upper column cap 300 and the lower column cap 200 are connected by a pin 302 and a connecting sleeve 201 in conjunction with a compression spring 303. This allows for quick disassembly and assembly without tools, facilitating later replacement or repair and greatly improving maintenance efficiency.

[0051] The top of the cap 301 has a reserved connection port 304 of a standardized interface type, which provides convenient and unified installation conditions for additional intelligent transportation facilities and meets the needs of modern transportation facilities.
