Abstract
Description
Technical Field
[0001] This utility model relates to the field of road traffic vehicle technology, and in particular to a road safety barrier. Background Technology
[0002] In existing roads, guardrails are commonly used to separate two adjacent lanes. After long-term use, existing guardrails will show surface wear and damage, often requiring the entire guardrail to be disassembled and replaced, which is inconvenient for later maintenance and has high maintenance costs. Summary of the Invention
[0003] In order to solve the above-mentioned technical problems, this utility model provides a road isolation pier, which has the advantages of low maintenance cost and easy maintenance.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a road safety barrier, including a base with an arc-shaped protrusion at the top. The base is wrapped with a crash strip on its outer edge. Crash structures are symmetrically arranged on the left and right sides of the arc-shaped protrusion. Each crash structure includes multiple crash blocks spaced apart along the bottom outer edge of the arc-shaped protrusion. The crash blocks are detachably connected to the arc-shaped protrusion through a connecting structure. The bottom of each crash block contacts the crash strip, and the inner side of each crash block fits against the arc-shaped protrusion.
[0006] In this solution, after prolonged use, the surface of the guardrail blocks will become damaged. The damaged guardrail blocks can be removed from the arc-shaped protrusions and replaced with new, unused guardrail blocks. This method is low-cost and easy to maintain.
[0007] Preferably, the connection structure includes a first threaded connection hole and two locking bolts disposed on the front and rear sides of the outer surface of the anti-collision block, and a second threaded connection hole is provided on the arc-shaped protrusion corresponding to the position of the first threaded connection hole, and the locking bolts are matched with the first threaded connection hole and the second threaded connection hole.
[0008] When a damaged bumper needs to be replaced, unscrew the locking bolts from the first and second threaded connection holes, then lift the bumper upwards to disengage it from the arc-shaped protrusion. Align the first threaded connection hole on the new, unused bumper with the corresponding second threaded connection hole, and then screw in the locking bolts to make the inner side of the new, unused bumper fit snugly against the arc-shaped protrusion. At this point, the bumper replacement is complete.
[0009] Preferably, the anti-collision block has symmetrical lifting grooves on both the front and rear sides.
[0010] Preferably, the outer side of the anti-collision block has an arc surface.
[0011] Preferably, the cross-sectional area of the anti-collision block gradually increases from bottom to top.
[0012] The cross-sectional area of the anti-collision block gradually increases from bottom to top, thereby increasing the force-bearing area of the anti-collision block.
[0013] Preferably, the top of the arc-shaped protrusion is provided with multiple mounting holes, which are spaced apart from front to back.
[0014] Preferably, the base has multiple weight-reducing holes at its bottom.
[0015] Weight-reducing holes can reduce the overall weight of the isolation pier, making it easier to install and reducing the workload during installation.
[0016] Preferably, the arc-shaped protrusion is further provided with a friction structure, the friction structure including multiple sets of friction protrusions arranged side by side from front to back, the friction protrusions including multiple friction protrusions arranged from left to right along the surface of the arc-shaped protrusion.
[0017] Preferably, adjacent friction protrusions are connected by a downwardly recessed arc-shaped connecting surface.
[0018] The beneficial effects of this utility model are: the damaged anti-collision block can be replaced through the connecting structure, which reduces maintenance costs and makes maintenance convenient; users can lift the anti-collision block upwards through the lifting groove for easy replacement; the weight reduction hole can reduce the overall weight of the isolation pier, making the installation of the isolation pier convenient and reducing the labor intensity during installation.

[0025] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0026] Example: A road safety barrier in this example, such as... Figures 1 to 5 As shown, it includes a base 1, with an arc-shaped protrusion 2 formed on the top of the base 1. The outer edge of the base 1 is wrapped with a crash strip 11. The arc-shaped protrusion 2 is symmetrically provided with crash structures on the left and right sides. The crash structure includes multiple crash blocks 3 spaced apart along the bottom outer edge of the arc-shaped protrusion 2. The crash blocks 3 are detachably connected to the arc-shaped protrusion 2 through a connecting structure. The bottom of the crash block 3 contacts the crash strip 11, and the inner side of the crash block 3 fits against the arc-shaped protrusion 2.
[0027] The connection structure includes a first threaded connection hole 32 on the front and rear sides of the outer surface of the anti-collision block 3 and two locking bolts. The arc-shaped protrusion 2 is provided with a second threaded connection hole 22 corresponding to the position of the first threaded connection hole 32. The locking bolts are matched with the first threaded connection hole 32 and the second threaded connection hole 22.
[0028] The anti-collision block 3 has symmetrical lifting grooves 33 on both the front and rear sides.
[0029] The outer side of the anti-collision block 3 has an arc surface.
[0030] The cross-sectional area of the anti-collision block 3 gradually increases from bottom to top.
[0031] The top of the arc-shaped protrusion 2 is provided with multiple mounting holes 6, which are spaced apart from front to back.
[0032] The base 1 has multiple weight-reducing holes 7 at its bottom.
[0033] The arc-shaped protrusion 2 is also provided with a friction structure, which includes multiple sets of friction protrusions arranged side by side from front to back. Each set of friction protrusions includes multiple friction protrusions 21 arranged from left to right along the surface of the arc-shaped protrusion 2. Adjacent friction protrusions 21 are connected by a downwardly recessed arc-shaped connecting surface.
[0034] In this solution, after the barrier is placed on the ground, the expansion bolts are screwed into the mounting holes to lock the barrier to the ground. After long-term use, the surface of the anti-collision blocks on the barrier will be damaged. When the damaged anti-collision blocks need to be replaced, the locking bolts are unscrewed from the first and second threaded connection holes. Then, the anti-collision block is lifted upward through the lifting groove to disengage the damaged anti-collision block from the arc-shaped protrusion. The first threaded connection hole on the new unused anti-collision block is aligned with the corresponding second threaded connection hole, and then the locking bolts are screwed in to make the inner side of the anti-collision block fit against the arc-shaped protrusion. At this point, the replacement of the anti-collision block is complete.
[0035] Weight-reducing holes can reduce the overall weight of the isolation pier, making it easier to install and reducing the workload during installation.
