Problems solved by technology

However, the traditional highway guardrail will produce a certain deformation after being hit, especially after being violently hit, the guardrail will produce a deformation that is difficult to recover
The deformed guardrail not only makes the maintenance of the guardrail troublesome, but also affects the overall appearance of the guardrail on the highway

specific Embodiment approach

[0069] Specific embodiments: the base 35 of the guardrail mechanism 1 in the present invention is all fixedly installed on the roadbed of the expressway. When the pendulum plate 7 and the elastic steel plate 3 between the guardrail square posts 32 of two adjacent guardrail mechanisms 1 were not bumped, the pendulum plate 7 and the guardrail square post 32 became vertical state, and the leaf spring 23 was not compressed, and the first The spring 13 is not stretched, and the buffer slider 19 on the fixed steel plate slider 14 is located in the trapezoidal groove 15 farthest from the opening of the steel plate slider sliding groove 12 among the five trapezoidal grooves 15, and the second spring 18 is not pressed. During compression, the end of the buffer slider 19 away from the second spring 18 passes through the buffer slider sliding groove 20; The tooth bar 26 is engaged; the guide block spring 39 is not compressed, the limit groove 38 of the guide block 40 communicates with th...

Abstract

The invention belongs to the technical field of guardrails, and particularly relates to a bufferable highway guardrail. The bufferable highway guardrail comprises a guardrail mechanism and an elasticsteel plate, wherein when a vehicle impacts a structure between two guardrail square columns, the elastic steel plate bends to absorb part of impact energy; in addition, energy is also consumed when afixed steel plate sliding block drives a buffer sliding block to move away from a pin; through the above design, the larger the impact force of the vehicle impacting a swing board and the elastic steel plate is, the greater the bending deformation of the elastic steel plate is, the more energy the elastic steel plate absorbs, the farther the fixed steel plate sliding block moves away from the pin, and the more energy is consumed when the fixed steel plate sliding block moves in the direction away from the pin, thereby achieving the function of buffering vehicle impact. When the vehicle impactforce is too large, the impacted guardrail mechanism enables the multiple front guardrail mechanisms and the elastic steel plates among the multiple guardrail mechanisms to be in linkage so as to buffer the remaining excessive impact energy, thereby playing a role in protecting drivers and passengers.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to a bufferable expressway guardrail. Background technique [0002] At present, highway guardrails are an important protective measure for preventing vehicles from rushing out of the highway after an accident. When the traditional highway guardrail is hit by a vehicle, the guardrail can absorb the energy after the impact, so that the vehicle is not easy to be severely crashed, and at the same time it can play a good role in protecting the vehicle and the passengers. However, the traditional highway guardrails will be deformed to a certain extent after being hit, especially after being violently hit, the guardrails will produce deformations that are difficult to recover. The deformed guardrail not only makes the maintenance of the guardrail troublesome, but also affects the overall appearance of the guardrail of the expressway. In order to enable the highway guardrail to return ...
