Embodiment 1

[0030] Example 1, such as Figure 2-3 As shown, the elastic protection mode: specifically describe the collision situation of the guardrail when the vehicle hits the guardrail 1 with a small impact force. When the guardrail 1 is installed, the guardrail 1 can be connected by installing holes at both ends of the guardrail 1, the alarm device 16 is connected with the wire 2, and simultaneously, the wire 2 is connected with the touch button 17. The anti-collision and shock absorption system 20 includes a crash plate 6, a rubber sleeve 8, a telescopic rod 5, a fixed plate 4 and a spring 7. Since the outer side of the crash plate 6 is arranged as a vertical fold structure 18, it has buffering and elastic capabilities. 6. The outer side is covered with a rubber sleeve 8, and the inner side of the anti-collision plate 6 is provided with several springs 7 between the telescopic rods 5.

Embodiment 2

[0033] Example 2, such as Figure 2-4 As shown, the self-damage protection mode: this embodiment specifically describes the collision situation of the guardrail when the vehicle 19 has a large impact force. When the guardrail 1 is installed, the guardrail 1 can be connected by being provided with installation holes at both ends of the guardrail 1, the warning device 16 is connected with the wire 2, and simultaneously, the wire 2 is connected with the touch button 17. Since the outer side of the anti-collision plate 6 is arranged as a vertical fold structure 18, which has cushioning and elasticity, the outer side of the anti-collision plate 6 is covered with a rubber sleeve 8, and the inner side of the anti-collision plate 6 is provided with several springs 7 between the telescopic rods 5. .

[0034] When there is a vehicle 19 hitting the guardrail, the impact force is relatively large, such as Figure 2-3 As shown, the first stage: the vehicle 19 first contacts the rubber sl...

Abstract

The invention discloses an anti-collision and shock-absorbing expressway guardrail, which comprises a guardrail and a support rod. The outer sides of the two guardrails are connected by a fixed plate and two telescopic rods. The outer side is a vertically folded anti-collision plate. There are several springs arranged between the two telescopic rods, the bottom ends of the two guardrails are symmetrically equipped with supporting rods, the four supporting rods are provided with placement slots, and the four supporting rods are connected A water tank is arranged in the isolation belt of the guardrail, a water pipe is installed on one side of the water tank, and a warning device is installed on the top of the water tank; the present invention has strong practicability, and an anti-collision and shock absorption system is formed by setting an anti-collision plate, a spring and a rubber sleeve. When the car hits the guardrail, it can relieve the impact force of the vehicle and prevent the serious injury of the people in the vehicle due to the excessive impact force. When the car is running, an alarm will be issued to remind other vehicles to avoid rear-end collisions.

Description

technical field [0001] The invention relates to an expressway guardrail, in particular to an anti-collision and shock-absorbing expressway guardrail, which belongs to the field of expressway guardrails. Background technique [0002] Highway guardrails are guardrails installed on both sides or in the middle of the expressway. When vehicles collide with them, they can protect them. However, the existing guardrails have poor anti-collision and shock absorption capabilities and cannot recover by themselves when subjected to a small impact. When suffering a large impact, it cannot protect the safety of personnel and vehicles, and when an accident occurs, it cannot protect the vehicle and warn other vehicles at the same time, reminding the driver that there is an accident, which is inconvenient to use. Contents of the invention [0003] The invention provides an anti-collision and shock-absorbing expressway guardrail, which solves the problems in the prior art that the guardrail...
