Buffer type anti-collision warning guardrail based on road and bridge construction

Abstract

The invention provides a buffer type anti-collision warning guardrail based on road and bridge construction, and relates to the field of municipal construction. The problems that the angle rotation guiding effect is not achieved, and direction changing and force unloading cannot be conducted after a vehicle is impacted; and fixing cannot be achieved at the same time through diversified fixing structures, the fixing structures cannot be adjusted, and the guardrail cannot adapt to supporting and fixing under different terrain environments are solved. The buffer type anti-collision warning guardrail based on road and bridge construction comprises a first frame, wherein an elastic damping structure is arranged on the first frame, and a second frame is rotationally connected to the elastic damping structure. The structure of a stress part is improved, firstly, a protective barrel is rotationally connected to a rotary connecting base C, the protective barrel and the rotary connecting base Cjointly form a protective type rotary connecting structure, force unloading can be achieved through rotation of the protective barrel after the vehicle makes contact with the protective barrel, and the strength of the protective barrel can be enhanced through reinforcing protrusions.

Description

technical field [0001] The invention belongs to the technical field of municipal construction, and more specifically relates to a buffer type anti-collision warning guardrail for road and bridge construction. Background technique [0002] With the development of society, the improvement of living standards, the population density is increasing, and there are many means of transportation, followed by the inconvenience and congestion of traffic, so municipal engineering has become a work that has to be done, and the protective fence is It has become an indispensable urban tool, whether it is on the street or in the park, the protective fence can be seen everywhere. [0003] For example, the application number: CN201920137818.6, the invention relates to a municipal buffer fence, which includes two vertical bars, two first horizontal bars are arranged between the two vertical bars, and both first horizontal bars are provided with Two connecting rods, the two connecting rods are...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a buffer type anti-collision warning guardrail based on road and bridge construction to solve the problem that the structure is not reasonable enough. Although the above application can achieve the purpose of multiple shock absorption, it does not have angular rotation Guiding function, after the collision of the vehicle, it is impossible to change the direction and unload the force, which increases the force of the fixed structure, and the structure is not reasonable enough; moreover, the fixed structure is single and has low functionality, which cannot be achieved through diversification. The fixed structure can be fixed at the same time, and the fixed structure is not adjustable, so it cannot adapt to the problem of support and fixation in different terrain environments
