Abstract
The utility model discloses a detachable arc safety guard fence for highways, which comprises a left upright post, a middle upright post and a right upright post, and is characterized in that two ends of an arc guard plate are fixed on the left upright post and the right upright post; the top of a retractable rod goes through a round hole in the middle upright post and is retractable in the hole; an impact reducing spring is sleeved on the retractable rod in the middle and pressed against the middle upright post; ten groups of arc guard plats from one to ten are arranged on the left upright post and the right upright post. The utility model adopts the elastic steel arc guard plates as the guard plates for highways, the retractable rod sleeved with impact reducing spring in the middle and capable of retraction in the round hole, and a multi-level buffer formed by the steel arc protective plates and the impact reducing spring so that the impact-proof power is greatly increased. The utility model has the advantage of good impact-proof performance, effective car-impact relief ability, reduced damage-degrees of accidents and safety protective function, therefore is a new protective equipment for highways.
Description
Technical field
The utility model relates to highway equipment, especially relates to a kind of split type arc high speed road safety guard.
Background technology
China has entered the speedway epoch at present, and all extend forward with thousands of kilometers speed every year, and speedway has greatly promoted development and national economy.The continuous repeatedly car crash accident of speedway also strikes the eye and rouse the mind simultaneously, because speedway is two-way using Correct Lane, the major accident reason of speedway is the collision of automobile and guardrail, slipperiness on roads, steering wheel is malfunctioning, brake is monolateral, driver fatigue, dealing with an urgent situation etc. all to cause automobile to hit guardrail, major accident can sever guardrail, automobile sweeps away gutter, the oblique wave of speedway, and more fearful is that automobile dashes to the road that drives in the wrong direction, and leads to more fearful accident.Guard bar structure on the speedway is too simple now, only is made up of left column, right column and backplate, and crashproof safety is not strong.
Summary of the invention
The purpose of this utility model be to provide a kind of crashworthiness good, can effectively alleviate the automobile impulsive contact force, alleviate the accident destructiveness, protection driver and crew safety, split type arc high speed road safety guard simple in structure.
The purpose of this utility model is achieved in that the utility model comprises left column, central post and right column, feature is that the two ends of arched backplate are fixed on left column and the right column, on central post, be processed with circular hole, nut is fixed on expansion link the centre of arched backplate, the centre is with to subtract and passes the circular hole on the central post towards the top of the expansion link of spring and can stretch in circular hole, and will subtract towards spring and be squeezed on the central post.
1-10 group arched backplate is installed between left column and right column.
The utility model is owing to adopt the backplate of rubber-like steel arched backplate as speedway, and middle be with to subtract pass the circular hole on the central post towards the top of the expansion link of spring and can in circular hole, stretch, the steel arched backplate constitutes multi-buffer with subtracting towards spring, thereby has strengthened anti-collision power greatly.When the take charge of running at high speed hits the roadside, headstock or vehicle body collision arched backplate, arched backplate is subjected to colliding distortion, makes expansion link further stretch into and pass circular hole, and extruding simultaneously subtracts towards spring, the opposition that arched backplate favorable rigidity, distortion produce and subtract towards the opposition of spring and stop automobile conversely jointly further forward, reduce the kinetic energy of automobile, thereby effectively alleviate the automobile impulsive contact force, force parking of automobile, alleviate the accident destructiveness, play the security protection effect.Therefore the utlity model has crashworthiness good, can effectively alleviate the automobile impulsive contact force, alleviate the accident destructiveness, play the security protection effect, simple in structure, installation is light, good looking appearance is novel, the advantage of multi-buffer is particularly arranged, and is a kind of novel speedway safeguard.
