Embodiment 1

[0037] like Figure 1 to Figure 3 As shown, the V-shaped road traffic safety guardrail of the present invention includes a column 100, an elastic rotating part 200 and a rail 300. The rail 300 is formed by connecting several rail bodies 310. The rail body 310 has two ends, one of which is Fitted on the column 100, the other end is rotatably combined with the elastic rotating part 200, and two adjacent rail bodies 310 are connected by the elastic rotating part 200 to form a V-shaped angle.

[0038]The inventor shortened the railing through a large number of experiments and improved the design of the structure. Two railing bodies 310 are arranged between two adjacent columns 100, and the two railing bodies 310 are connected by elastic rotating parts 200 to form a V-shaped angle. If the long horizontal rail in the prior art is replaced with the horizontal rail composed of the multi-section horizontal rail body of the present invention, the overall strength of the horizontal rail...

Embodiment 2

[0050] like Figure 4 to Figure 6 As shown, a V-shaped road traffic safety guardrail of the present invention includes a column 100, an elastic rotating part 200 and a horizontal bar 300. The horizontal bar 300 has two ends, one of which is sleeved on the column 100, and the other end is rotated and combined with an elastic The rotating part 200, two adjacent rails 300 are connected by the elastic rotating part 200 and form a V shape; the column 100 has a tubular structure and is erected on the side of the road at a constant interval; the elastic rotating part 200 includes an elastic rotating body 210 and a rotating shaft 220 , the shape of the elastic rotating body 210 is a conical body, the top is large and the bottom is small, the taper can be in the range of 3-5°, the best value is 5°, the elastic rotating body 210 has a passage through the elastic rotating body 210 from its upper part to the bottom The rotating shaft 220 is inserted into the through hole of the elastic ro...

Abstract

The invention discloses a V-shaped road transportation safety guardrail belonging to the technical field of traffic protecting equipment. The V-shaped road transportation safety guardrail comprises arail which is formed by connecting a plurality of rail bodies and two adjacent rail bodies form a V-shaped included angle. By changing the design concept of an existing safety guardrail, the rail is shortened, and the two adjacent rail bodies are connected through an elastic rotary part to form the V shape, so that the connecting strength of the rail and the column is high. Even if the rail is collided with a vehicle, the vehicle does not cross the rail, and meanwhile, the mounting process is simplified with one to two persons, and the quantity of operators is small. In addition, the road transportation rail is more conveniently mounted. In a project building process, the mounting time of the transportation guardrail can be shortened greatly, thereby providing guarantee to use of a road immediately.

Description

technical field [0001] The invention belongs to the technical field of traffic protection equipment, and more specifically relates to a V-shaped road traffic safety guardrail capable of absorbing impact force, which can be installed in the middle of the road, on the side of the road or at a turning. 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 concrete b...
