Embodiment 1

[0041] Such as Figure 1 to Figure 3As shown, the road traffic safety guardrail of the present invention includes a column 100, an elastic rotating part 200, a rail 300 and a rail combining part 400. The column 100 has a tubular structure and is erected on the side of the road at constant intervals; the constant Interval is determined according to the national road guardrail standard, for example, the distance between the post installation of road guardrail is 2.5-3m, and the installation distance that can be selected is 3m; 210) is in the shape of a cylinder, and the rotating shaft 220 and the elastic rotating body 210 form an integrated structure, that is, the rotating shaft 220 and the elastic rotating body 210 rotate simultaneously or remain still. It is worth noting that since the national road guardrail standard stipulates that the diameter of the column is 140 mm, the existing elastic rotating body is set on the column 100. In this way, if the through hole of the elasti...

Embodiment 2

[0055] Such as Figure 4 to Figure 6 As shown, a road traffic safety guardrail of the present invention includes a column 100, an elastic rotating part 200, a rail 300 and a rail combining part 400. The column 100 has a tubular structure and is erected on the side of the road at constant intervals; the elastic The rotating part 200 includes an elastic rotating body 210 and a rotating shaft 220. The elastic rotating body 210 is in the shape of a cone, with a large top and a small bottom. The taper can be in the range of 3-5°, and the best value is 5°. It runs through the through hole of the elastic rotating body 210 from the top to the bottom, and the rotating shaft 220 is inserted into the through hole of the elastic rotating body 210 to form an integrated structure; An installation hole 310 is provided, and the rotating shaft 220 is penetrated in the installation hole 310 and is rotatably combined to support the elastic rotating member 200 ;

Abstract

The invention discloses an elastic rotating component and a road traffic security fence, and belongs to the technical field of traffic protective equipment. The elastic rotating component comprises anelastic rotating body and a rotary shaft, the elastic rotating body and the rotary shaft are of an integral structure, the rotary shaft rotates relative to cross fences, the diameter of the rotary shaft is relatively small, the diameter of the corresponding elastic rotating body is relatively small, thus the production cost is lowered, the impact energy can be well absorbed, and accordingly the safety of personnel in a car is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of traffic protection equipment, and more specifically relates to an elastic rotating part capable of absorbing impact force and a road traffic safety guardrail, which can be arranged in the center of the road or on the side of the road. Background technique [0002] Vehicles are more and more used by people as a convenient means of transportation. In our country, the speed limit of urban roads is generally 40 kilometers per hour, the general speed of ordinary roads is 40-80 kilometers per hour, and the general speed of expressways is 60-120 kilometers per hour, so there are many traffic accidents in urban areas. For rear-end collision accidents, on ordinary roads or expressways, traffic accidents occur frequently due to excessive vehicle speed, the most serious of which is that high-speed vehicles hit the guardrails on the side of the road or in the middle of the road, and these guardrails are made of concr...
