Description
Technical field:
The present invention relates to a kind of road anticollision device, collision-prevention device, in particular to a kind of elastic helix drum-type anticollision device, collision-prevention device and elasticity rolling
Kinetoplast.
Background technique:
Highway belongs to high-grade highway, has the characteristics that speed is high, the traffic capacity is big, adapts to 120 kilometers/hour
Or there is a width in 4 or more lanes on higher speed, road surface, centre setting intermediate isolating hoarding, to by shuttle traffic every
It leaves and, using bituminous concrete or cement concrete high class pavement, equipped with complete mark, graticule, signal and lighting device；
Forbid pedestrian and non motorized vehicle on the way to walk, is passed through with All other routes using crossings on different level, pedestrian's overbridge or tunnel, for
The reduction of transportation cost and energy consumption plays positive effect.
According to statistics, China is annual occurs traffic accident about 500,000, because toll on traffic is more than 100,000 people, occupies generation
Boundary first；As soon as statistical data shows just to have for every 5 minutes people to lose one's life wheel, there is within every 1 minute people disability due to traffic accident,
Every year because caused by traffic accident economic loss up to tens billion of.Although highway plays economic and social development important
Effect, but the vehicle speed per hour due to travelling on a highway, generally all at 80-120 kilometers/hour, vehicle has very big
Kinetic energy, once due to blowing out, fatigue driving, driving demand power are not concentrated, driver behavior is improper is likely to occur to hit high speed
The case where highway intermediate isolating hoarding.Intermediate isolating hoarding among highway is generally that (centre plants by single or double layer
Kind of flowers and plants) cement hard material piles up, and when accident vehicle is hit with it, hard material is piled up into intermediate isolating
Plastic deformation cannot occur for hoarding to absorb the shock kinetic energy of vehicle, and vehicle and intermediate isolating hoarding are hit and the active force of generation
Injuring for vehicle and personnel can be directly contributed；Meanwhile vehicle and intermediate isolating hoarding be when hitting, intermediate isolating hoarding and vehicle it
Between generate sliding friction, coefficient of friction is very big, will cause direction of traffic it is out of hand and rebound return, lead to vehicle and personnel
Injure, also will affect the vehicle that other are run at high speed when serious and cause secondary car accident, vehicle and personnel are caused
Serious injury, traffic mortality is higher.
Currently, the anticollision device, collision-prevention device for road is generally rotary shaft anticollision device, collision-prevention device, certain snubber can be played
Automobile impacting energy and the effect that automobile direction of travel is guided, can reduce to a certain extent to vehicle injure and
Injury to personnel, but still there are the following problems: 1, application range smaller, should all be used in urban transit system road or slow traffic
At the import corner of road, road boundary, the car speed of these application places is generally lower, and the traffic accident of generation is most
It is generally smaller for accidents, the damage sequence such as scratch and knock into the back；2, its basic structure be with certain elasticity, can be coaxial
The runner of rotation, deforms the shock kinetic energy for absorbing automobile by runner, runner by steel shaft and shaft up and down each one
A bearing connects that be formed can be with the mechanical structure of axial-rotation, and is supported by steelframe, and supporting steel frame is mounted on metal material system again
On the road isolated gate of work, to form road traffic guardrail, and anti-collision effect is played, can not be mounted in highway and be spaced
From hoarding；And fabrication and installation are time-consuming and laborious, are not easy to promote.
Summary of the invention:
The first purpose of this invention is that vehicle and personal injury can be reduced, reduce traffic accident death by providing one kind
Rate is easily installed, the elastic helix drum-type anticollision device, collision-prevention device that the scope of application is wider.
Second object of the present invention is to provide a kind of elastic rolling body for elastic helix drum-type anticollision device, collision-prevention device.
The first purpose of this invention is implemented by following technical solution: elastic helix drum-type anticollision device, collision-prevention device comprising base
Plate and several elastic rolling bodies, several described elastic rolling bodies are distributed along the length direction of the substrate, each bullet
Property rolling element by connect empennage connect with the substrate；One end of the connection empennage surrounds the outer wall of the elastic rolling body
Wrap up the elastic rolling body, the other end of the connection empennage is fixedly connected with the substrate, when there is bullet described in Vehicular impact
Property rolling element when, the elastic rolling body carries out shaftless rolling along the substrate.
Further, the elastic rolling body includes soft shell, and elastic buffer body is filled with inside the soft shell.
Further, the soft shell is any one in hollow cylindrical body, round estrade or sphere.
