Safe and firm noise-preventing novel highway guardrail

Abstract

The invention discloses a safe and firm noise-preventing novel highway guardrail which comprises a frame, acrylic rotary barrels, first bearing seats, buffer boards and a supporting arm. Connecting transverse boards are horizontally arranged on the upper portion and the lower portion of the frame, the acrylic rotary barrels are arranged on the left side of the portion between the connecting transverse boards, and the two ends of each acrylic rotary barrel are rotationally connected with the frame through the first bearing seats. The buffer boards are arranged on the right side of the acrylic rotary barrels, the supporting arm is arranged on the right side of the buffer boards, fixing blocks are fixedly welded to the middle positions of the upper surface and the lower surface of the supporting arm, the fixing blocks are connected with the middle position of the frame through second bearing seats, the inside of each buffer board is of a hollow structure, rubber buffer cushions are arranged at the upper ends and the lower ends of the left sides of inner cavities of the buffer boards, and metal net pore plates are arranged between the rubber buffer cushions. The guardrail is reasonablein arrangement, stable in supporting and capable of efficiently absorbing noise on a highway, reducing noise pollution and protecting safety of a driver and a vehicle.

Description

technical field [0001] The invention relates to the technical field of road equipment, in particular to a new type of safe and firm anti-noise road guardrail. Background technique [0002] Guardrails refer to industrial "guardrails". Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. Depending on the height of the guardrail, the price per meter of length will also vary. The guardrail is usually made of steel, such as: stainless steel, round steel pipe, square steel pipe or profiled steel plate, iron wire. Surface treatment process: automatic electrostatic powder spraying (that is, plastic spraying) or painting. In recent years, plug-in and assembled guardrails made of aluminum alloy have become more popular. It is usually made of steel, such as round steel pipe, square steel pipe or profil...

Problems solved by technology

[0003] With the rapid development of science and technology, our living standards are constantly improving. Now most people have cars at home. Cars are convenient for us to travel and are currently the most important means of transportation. When cars are driving on high-speed kilometers, both sides There will be guardrails to prevent cars from drifting off the road and causing traffic accidents, but the current guardrails have no anti-collision effect, so when a car hits the guardrail, it will still cause traffic accidents, because there is no anti-collision device on the guardrail. When guardrailing, the instantaneous impact force is too large, causing damage to cars and casualties. Moreover, the existing road guardrail has a single structure and does not have the function of eliminating noise. When there are many vehicles driving on the road, it will cause noise pollution to the external environment. , affecting the normal life of residents near the road, and most of the existing road guardrails do not have reflective ability at night, and need to be artificially pasted with reflective strips, which not only troubles the operation, but also brings safety hazards to the operator, and the reflective strips It needs to be replaced and cleaned regularly, which consumes a lot of manpower and material resources
