Description

Technical Field

[0001] The utility model relates to the field of highway safety protection supporting facility engineering, in particular to an elastic anti-collision guardrail. Background Art

[0002] The current highway guardrail is composed of two corrugated steel guardrails and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrails. There are also designs for roller guardrails; when the highway is in normal operation, the guardrail can be easily inserted into the pre-set plug-in holes at the opening by using the plug-in columns, which plays a role of isolation and protection, and at the same time echoes the guardrail belt on the outside of the highway, which is neat, uniform, and beautiful.

[0003] However, neither corrugated steel guardrail nor roller guardrail can withstand strong direct impact. Therefore, if you are designing a sharp turn on a mountain road, the above guardrail is not very suitable. Generally, thick cement blocks (guardrails) are used to prevent it. However, cement blocks generally occupy a larger area, which will further reduce the width of the road surface on the sharp turn. Summary of the invention

[0004] The utility model aims to provide an elastic anti-collision guardrail, which can solve the problem of insufficient capacity of corrugated steel guardrail plates.

[0005] The utility model is realized by the following technical scheme: an elastic anti-collision guardrail, which comprises:

[0006] A supporting column is vertically arranged on the ground and the lower end is embedded in the ground;

[0007] A connecting portion, connected to the upper portion of the supporting column by bolts;

[0008] The elastic anti-collision box is fixedly connected to the connecting part; an elastic device is arranged inside the elastic anti-collision box.

[0009] Compared with the previous technology, the beneficial effects of the utility model are:

[0010] 1. The elastic anti-collision plate has good impact strength and buffering ability, which can partially absorb the impact force of the vehicle, effectively protect the vehicle and the people inside the vehicle, and at the same time reduce the damage to itself during the collision.

[0011] 2. The fixed chain and the connecting chain can act as a structure similar to a net, so that when the highway guardrail is damaged or knocked off the ground, the fixed chain can catch the vehicle, and because the fixed chain and the connecting chain are connected to the ground, they can support the vehicle and prevent the vehicle from falling.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0019] like Figures 1 to 5 As shown, an elastic anti-collision guardrail comprises:

[0020] A support column 1 is vertically arranged on the ground and the lower end is embedded in the ground;

[0021] The connecting part 2 is connected to the upper part of the supporting column 1 by bolts 12;

[0022] The elastic anti-collision box 3 is fixedly connected to the connecting part 2; an elastic device 31 is arranged inside the elastic anti-collision box 3. The elastic anti-collision plate has good impact resistance and buffering capacity, effectively absorbs impact force, protects the vehicle and the people in the vehicle, and can also reduce the damage to itself during the collision process.

[0023] The elastic device 31 is a spring. A buffer pad can also be filled inside the elastic anti-collision plate as the elastic device.

[0024] The support column 1, the connecting part 2 and the elastic anti-collision box 3 are all provided with a fixing chain 4;

[0025] The connection part 2 and the elastic anti-collision box 3 are both provided with a fixed chain 4; and the connection part 2 and the fixed chain 4 provided in the elastic anti-collision box 3 are connected to each other at their intersections;

[0026] The bottom ends of the fixing chains 4 of the supporting columns 1 extend below the ground, and the bottom ends of the fixing chains 4 of the supporting columns 1 are connected through connecting chains 41 , so that a plurality of fixing chains 4 are connected to the ground through the connecting chains 41 to form a whole.

[0027] The fixed chain and the connecting chain can act like a net, so that when the highway guardrail (support column 1) is damaged or knocked off the ground, the fixed chain can hold the vehicle, and because the fixed chain and the connecting chain are connected to the ground, they can support the vehicle and prevent it from falling. At the same time, the fixed chain itself also plays a further buffering role.

[0028] The upper end surface of the support column 1 is also provided with a column cover plate 11. The technology of the column cover plate is relatively conventional, so it will not be described in detail.

[0029] The elastic anti-collision box 3 is connected to the connecting part 2 via a threaded structure;

[0030] The threaded structure is a nut 33 provided in the connecting portion 2 and a screw 32 provided on the elastic anti-collision box 3;

[0031] The screw 32 penetrates the elastic anti-collision box 3 and penetrates the connecting portion 2 to be connected with the nut 33. The thread structure is relatively conventional, so it will not be described in detail.

[0032] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
