Road traffic guardrail capable of buffering and absorbing impact

Abstract

The invention discloses a road traffic guardrail capable of buffering and absorbing impact. The road traffic guardrail is characterized by comprising fastening pieces; each fastening piece is provided with two ends and a connecting part used for connecting the two ends, wherein the two ends are used for applying force to an upper horizontal column or a lower horizontal column; power is transmitted to the connecting part from the two ends; and the upper horizontal column or the lower horizontal column is subjected to the force and moves relative to a corresponding round tube stand column, so that the upper horizontal column or the lower horizontal column is fixed to the round tube stand column. The road traffic guardrail capable of buffering and absorbing impact is simple in structure; the fastening pieces are adopted for fixing the upper horizontal column and the lower horizontal column; on the one hand, the fastening pieces are high in strength and guarantee the anti-impact performance of the upper horizontal column and the lower horizontal column, on the other hand, the upper horizontal column and the lower horizontal column can move relative to the round tube stand columns only by applying force to the connecting parts of the fastening pieces in the mounting process, and therefore, fixation is achieved; mounting is convenient and fast, and the labor efficiency is greatly improved; and at the same time, a smaller number of screw rods are used, and the production cost is lowered.

Description

technical field [0001] The invention relates to a traffic guardrail, in particular to a road traffic guardrail capable of buffering and absorbing impacts, which can be arranged in the middle of the road or on the side of the road. Background technique [0002] With the rapid development of economy, automobiles are widely used as a convenient means of transportation. In my country, the speed limit of different roads is also different. For example, the general speed limit of urban roads is 40 kilometers per hour, the general speed of ordinary roads is 40-80 kilometers per hour, and the general speed limit of expressways is 60-120 kilometers per hour. Therefore, traffic accidents in urban areas are mostly rear-end collision accidents. On ordinary roads or expressways, traffic accidents occur frequently due to excessive speed of vehicles. On the guardrail, and these guardrails are made of concrete bricks or concrete blocks arranged at intervals and cross rails connecting adjacent...

Problems solved by technology

[0006] The structures of the above three guardrails are relatively complex. In actual use, due to structural limitations, the installation is time-consuming, labor-intensive, and work-efficient. In addition, due to the large friction between the elastic rotating body and the rotating receiving plate , the effect of absorbing and buffering the impact is poor, that is, the impact cannot be well absorbed, so that the occurrence of secondary traffic accidents cannot be avoided
