Description
Technical Field
[0001] This utility model relates to the field of crash barrier technology, and in particular to a tamper-proof structure for a pile cap of a highway crash barrier. Background Technology
[0002] In the field of highway traffic safety facilities, crash barriers are important protective devices that ensure vehicle driving safety and prevent vehicles from running off the road. The piles used to fix and support the crash barriers, as well as the pile caps covering the top of the piles, are indispensable components of the overall structure of the crash barriers.
[0003] Traditional highway crash barrier caps are mostly installed using simple snap-on or screw-fixing methods. Snap-on caps are fixed by a simple interlocking of the edge protrusions with the groove on the top of the post, resulting in a loose structure that is prone to falling off under external prying or vibration. While screw-fixing provides slightly better stability, the screws are exposed and easily unscrewed with tools. Furthermore, they are susceptible to rust and jamming due to long-term exposure to wind and rain, affecting the convenience of disassembly and maintenance and making it difficult to prevent intentional damage or theft. Therefore, we propose an anti-dismantling structure for highway crash barrier caps. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an anti-dismantling structure for the pile cover of highway crash barriers. This can solve the problem that traditional highway crash barrier pile covers are mostly installed using simple snap-on or screw fixing methods. Snap-on pile covers are fixed by simple interlocking of the edge protrusions with the groove on the top of the column, which is loose and easy to fall off under external prying or vibration. Although screw fixing is slightly more stable, the screws are exposed to the outside and are easy to be unscrewed with tools. Moreover, they are prone to rust and jamming due to long-term erosion by wind and rain, which not only affects the convenience of disassembly and maintenance, but also makes it difficult to resist deliberate damage or theft.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tamper-proof structure for a highway crash barrier cap, comprising:
[0006] The system consists of a fixed base plate, a main body of the crash barrier, and a main body of the pile cap. The main body of the crash barrier is fixedly connected to the top of the fixed base plate, and the main body of the pile cap is installed on the top of the main body of the crash barrier.
[0007] The anti-removal mechanism for the pile cover is located on the main body of the crash barrier.
[0008] The anti-dismantling mechanism for the pile cover includes three elastic plates, a retaining ring, a connecting post, and a limiting block. The three elastic plates are all fixedly connected to the bottom of the pile cover body, the retaining ring is fixedly connected to the inside of the anti-collision guardrail body, and the bottom ends of the three elastic plates are all snapped onto the retaining ring. The connecting post is fixedly connected to the bottom end of the pile cover body, and the limiting block is fixedly connected to the outer surface of the connecting post.
[0009] Preferably, the anti-dismantling mechanism of the pile cover further includes four support plates and a limiting plate. The four support plates are all fixedly connected inside the body of the anti-collision railing. The top of the four support plates is fixedly connected to the limiting plate. The top of the limiting plate is provided with a through hole and a limiting groove, and the through hole and the limiting groove are connected inside.
[0010] Preferably, the docking post is slidably connected to the inside of the through hole, and the limiting block is slidably connected to the inside of the limiting groove.
[0011] Preferably, the outer surface of the pile cover body is provided with an insertion hole, and a positioning block is fixedly connected to the top of the anti-collision railing body.
[0012] Preferably, the insertion hole and the limiting block are at the same horizontal level, and the positioning block and the limiting groove are at the same horizontal level.
[0013] Preferably, the three elastic plates are arranged in a circular array on the pile cap body.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This highway crash barrier uses a pile cover anti-dismantling structure. The circular array of elastic clamping plates and the tight snap-fit with the clamping rings, along with the cooperation of the connecting posts, limiting blocks, and limiting discs, make it impossible for the pile cover body to be easily disassembled. This effectively prevents unauthorized personnel from disassembling, damaging, or replacing the pile cover, avoiding problems such as exposure, damage, or functional failure of the internal structure of the crash barrier due to the removal of the pile cover. This ensures the normal use and safety of the highway crash barrier, thereby increasing the difficulty of disassembly and requiring specific tools and operating methods to disassemble. This raises the cost and threshold of damage, thus better protecting highway facilities. Attached Figure Description

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0027] Please see Figure 1-4 This utility model provides a technical solution: a tamper-proof structure for a highway crash barrier cap, comprising:
[0028] The base plate 2, the main body 1 of the crash barrier, and the main body 3 of the pile cover are fixedly connected to the top of the base plate 2, and the main body 3 of the pile cover is installed on the top of the main body 1 of the crash barrier.
[0029] The anti-dismantling mechanism for the pile cover is located on the main body 1 of the crash barrier.
[0030] The anti-dismantling mechanism of the pile cover includes three elastic clamping plates 10, a retaining ring 7, a connecting post 6, and a limiting block 13. The three elastic clamping plates 10 are all fixedly connected to the bottom of the pile cover body 3. The retaining ring 7 is fixedly connected to the inside of the anti-collision guardrail body 1. The bottom ends of the three elastic clamping plates 10 are all snapped onto the retaining ring 7. The connecting post 6 is fixedly connected to the bottom end of the pile cover body 3. The limiting block 13 is fixedly connected to the outer surface of the connecting post 6. The three elastic clamping plates 10 are arranged in a circular array on the pile cover body 3.
[0031] The anti-dismantling mechanism of the pile cover also includes four support plates 8 and a limiting plate 9. The four support plates 8 are all fixedly connected inside the main body 1 of the anti-collision railing. The top of the four support plates 8 are all fixedly connected to the limiting plate 9. The top of the limiting plate 9 is respectively provided with a through hole 11 and a limiting groove 12. The through hole 11 and the limiting groove 12 are connected internally.
[0032] The connecting column 6 is internally slidably connected to the through hole 11, the limiting block 13 is internally slidably connected to the limiting groove 12, the outer surface of the pile cover body 3 is provided with an insertion hole 4, the top of the anti-collision railing body 1 is fixedly connected with a positioning block 5, the insertion hole 4 and the limiting block 13 are at the same level, and the positioning block 5 and the limiting groove 12 are at the same level.
[0033] Furthermore, when using this device, during the installation of the pile cover body 3, since the elastic clamping plate 10 is made of metal and has elasticity, the elastic clamping plate 10 can deform appropriately during the installation process of the pile cover body 3 onto the top of the crash barrier body 1, making it easy for the pile cover body 3 to be initially placed in a suitable position at the top of the crash barrier body 1. As the pile cover body 3 continues to be pressed down, the bottom ends of the three elastic clamping plates 10 are snapped onto the retaining rings 7 fixed inside the crash barrier body 1. The retaining rings 7 provide stable snapping points for the elastic clamping plates 10. Through the snapping cooperation between the elastic clamping plates 10 and the retaining rings 7, the pile cover body 3 is fixed on the crash barrier body 1, preventing the pile cover body 3 from falling off.
[0034] The docking column 6, which is fixedly connected to the bottom of the pile cover body 3, will slide into the through hole 11 on the limiting plate 9 connected to the top of the four support plates 8 inside the anti-collision guardrail body 1 during the installation process of the pile cover body 3. At the same time, the insertion hole 4 on the pile cover body 3 and the positioning block 5 are placed at the same horizontal position, so that the limiting block 13 fixed on the outside of the docking column 6 will also slide into the limiting groove 12 on the limiting plate 9 that communicates with the inside of the through hole 11. This process ensures the accurate positioning of the pile cover body 3 in the vertical direction. Then, an external tool is inserted into the through hole 11 to rotate the pile cover body 3, so that it is misaligned with the positioning block 5, which further enhances the stability of the installation of the pile cover body 3.
[0035] The circular array of the elastic clamping plate 10 and its tight snap-fit with the clamping ring 7, along with the cooperation of the docking post 6 and the limiting block 13 with the limiting plate 9, make it impossible for the pile cover body 3 to be easily disassembled. This effectively prevents unauthorized personnel from disassembling, damaging, or replacing the pile cover, avoiding problems such as exposure, damage, or functional failure of the internal structure of the crash barrier that may result from the removal of the pile cover. This ensures the normal use and safety of the highway crash barrier, thereby increasing the difficulty of disassembly and requiring specific tools and operating methods to disassemble. This raises the cost and threshold of damage, thus better protecting highway facilities.
