Description

Technical Field

[0001] This utility model relates to the field of transportation engineering technology, and in particular to a high-speed crash barrier. Background Technology

[0002] Traffic crash barriers are traffic safety facilities installed on traffic dividers and the outer side of road shoulders. They absorb collision energy through self-deformation, thereby changing the direction of vehicle travel and preventing vehicles from running off the road, and reducing injury to drivers and passengers. Currently, most highway crash barriers in cities mainly use corrugated guardrails. Although they are low in cost and easy to install, their shock absorption capacity is poor and they cannot effectively reduce the impact generated when vehicles collide with them, increasing the risk of accidents after a vehicle collides with the guardrail. Utility Model Content

[0003] The purpose of this utility model is to provide a high-speed crash barrier in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A high-speed crash barrier includes columns spaced side-by-side along the side of a highway, with a base plate fixed to the lower end of each column. A connecting ring is provided on the side of each column closest to the highway, and corrugated plates are installed on adjacent connecting rings. A buffer mechanism is provided between the columns for shock absorption and buffering of colliding vehicle bodies. The buffer mechanism includes a crossbeam fixed between the columns, with two points of the crossbeam arranged opposite each other. A mounting base is fixed on the side of the crossbeam closest to the road surface, and two support rods are provided on the mounting bases. A damping shock absorber is provided on one side of each support rod. The damping shock absorber, support rods, and crossbeam are arranged in a triangular shape. A connecting seat is provided at the end of the damping shock absorber and support rods away from the crossbeam. A connecting rod is provided between the connecting seats, and a buffer cylinder is provided between the upper and lower connecting seats.

[0006] Further details: The damping shock absorber rod and the support rod are rotatably connected to the connecting seat via pins, and the support rod is rotatably connected to the mounting seat.

[0007] Further configuration: The buffer cylinder is rotatably connected to the connecting seat, and the connecting rod is rotatably connected to the connecting seat.

[0008] Further features: Reflective rings are spaced apart on the outer diameter of the buffer cylinder, and the outer tangent of the buffer cylinder protrudes from the corrugated plate.

[0009] Further details: The connecting ring is welded to the column, and the corrugated plate is connected to the connecting ring by bolts. There are two locations on the corrugated plate, one at the top and one at the bottom.

[0010] Further configuration: The buffer cylinder is placed between the upper and lower corrugated plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting up a buffer mechanism between the pillars, when a vehicle rushes toward the roadside, it first contacts the buffer cylinder. The buffer cylinder rotates, causing the impact force to tilt forward. At the same time, the damping shock absorber rod buffers the deformation. The damping shock absorber rod and the support rod rotate at an angle relative to the crossbeam, increasing the buffering force against the impact. Then the vehicle contacts the corrugated plate, which transmits the force to the connecting ring, buffering the impact force again. This achieves powerful buffering during vehicle impact.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a high-speed crash barrier includes columns 1 arranged side by side at intervals along the side of the highway. A base plate 11 is fixed to the lower end of the column 1. A connecting ring 21 is provided on the side of the column 1 closest to the highway. A corrugated plate 22 is installed on the adjacent connecting ring 21. A buffer mechanism is provided between the columns 1 for shock absorption and buffering of the colliding vehicle body.

[0024] In this embodiment: the buffer mechanism includes a crossbeam 31 fixed between the columns 1. Two crossbeams 31 are arranged vertically opposite each other. A mounting base 32 is fixed to the side of the crossbeam 31 closest to the road surface. Two support rods 33 are mounted on the mounting base 32. A damping shock absorber rod 34 is mounted on one side of each support rod 33. The damping shock absorber rod 34, support rod 33, and crossbeam 31 are arranged in a triangular shape. A connecting seat 35 is provided at the end of the damping shock absorber rod 34 and support rod 33 away from the crossbeam 31. A connecting rod 36 is provided between the connecting seats 35, allowing the connecting rod 36 to connect and support the buffer cylinders 37 at two adjacent locations. To improve the overall support effect, a buffer cylinder 37 is provided between the upper and lower connecting seats 35; the damping shock absorber rod 34 and the support rod 33 are rotatably connected to the connecting seat 35 through pins, and the support rod 33 is rotatably connected to the mounting seat 32; the buffer cylinder 37 is rotatably connected to the connecting seat 35, and the connecting rod 36 is rotatably connected to the connecting seat 35, so that after the buffer cylinder 37 is subjected to the impact force of the vehicle, the buffer cylinder 37 rotates to reduce the force, while the damping shock absorber rod 34 buffers the deformation. The damping shock absorber rod 34 and the support rod 33 rotate at an angle relative to the crossbeam 31 to increase the buffering force against the impact force.

[0025] Reflective rings 38 are spaced apart on the outer diameter of the buffer cylinder 37 to warn vehicles. The outer tangent of the buffer cylinder 37 protrudes from the corrugated plate 22, so that when the vehicle hits the guardrail, it first contacts the buffer cylinder 37. The connecting ring 21 is welded to the column 1, and the corrugated plate 22 is connected to the connecting ring 21 by bolts. There are two corrugated plates 22, one above the other. The buffer cylinder 37 is placed between the upper and lower corrugated plates 22.

[0026] The working principle and usage process of this utility model are as follows: When a vehicle collides with the roadside, the vehicle first contacts the buffer cylinder 37. The buffer cylinder 37 rotates, causing the impact force to tilt forward. At the same time, the damping shock absorber 34 is buffered and deformed, causing the positions of the damping shock absorber 34, the support rod 33, and the buffer cylinder 37 relative to the crossbeam 31 to buffer the impact force of the vehicle. Then, the vehicle contacts the corrugated plate 22, and the corrugated plate 22 transmits the force to the connecting ring 21, which buffers the impact force again.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
