Description

Cushion guardail

Technical field

The utility model is related to a kind of freeway infrastructure, and in particular to a kind of cushion guardail.

Background technology

In highway both sides and the isolation strip of centre, in order to prevent car where high-speed cruising vehicle is gone out because of a variety of causes Outside road, design and installation freeway guardrail.As highway, city intersection, overpass etc. are largely built, traffic fortune Defeated net is increasingly intensive, while Global Auto recoverable amount increases substantially year by year, the incidence of traffic accident is also in ascendant trend year by year. According to the event that the central guardrail of 250 shocks is there are about in data statistics every year on average every 200 meters of highways, this kind of event is high As many as 3 times of other type traffic accidents on fast road, and because guardrail it is overly hard can not to impact buffer caused by it is great The accident of injures and deaths is in the great majority.

Existing freeway guardrail is broadly divided into rigid concrete guardrail, semi-rigid corrugated guardrail and flexible cable guardrail Three kinds.From the point of view of structure and security performance, existing freeway guardrail is primarily present the defect of following several respects：Concrete is protected Though column wall face-type structural can prevent big heavy vehicle from running off guardrail, can effectively contain that dilly gets out guardrail substantially, due to Concrete deforms upon very little when bearing external load effect, therefore the kinetic energy of the vehicle absorbed in collision process by guardrail is very Few, the dynamic shear force that collision vehicle is subject to is very big, easily causes vehicle heavy damage, or even cause passenger's injures and deaths；Half Though rigid wave shaped guardrail has good comprehensive mechanical property, have to general vehicle collision and preferably resist and guiding function, The absorption to vehicle energy of corrugated guardrail is not big enough, and certain injury can be still caused to vehicle and passenger；Flexible cable guardrail Because the contact area in knockout process with vehicle is smaller, the finite energy of absorption only has to the shock of car and preferably blocked Cut and guide effect, flexible cable guardrail intensity is weaker, oversize vehicle, which can still exist, thrusts the possibility that guardrail goes out road.

To sum up, domestic three kinds of major type of freeway guardrails can not only meet rigidity but also wanting with energy-absorbing at present Ask, if meeting rigidity, the dynamic shear force that collision vehicle is subject to is big, destructive big；Certain energy-absorbing requirement to that can meet, Then the insufficient strength of corresponding guardrail is big, the hot-short of big quality can not be intercepted effectively, the scope of application is smaller.At present, Semi-rigid corrugated guardrail is the relatively good selection of most highways, and semi-rigid corrugated guardrail is typically by metal material processing Guardrail board into column tube and connecting upright pole pipe is constituted, and the structure is due to the evil month after month drenched in wind, Exposure to Sunlight, sleet throughout the year In bad environment, easily corrosion is damaged, and has severely impacted its service life, meanwhile, semi-rigid corrugated guardrail does not have preferably Energy-absorbing is designed, and its energy-absorbing is limited, it is only possible to reaches buffering effect by flow of metal, preferably personnel can not be avoided to hinder Die, on the other hand, after Vehicular impact, inertia force may cause vehicle to continue preshoot, and preshoot process rubs with guardrail Easily light the gasoline of leakage and then cause fire.Therefore, this kind of semi-rigidity rail is further improved.

Utility model content

Preferably, column upper end is fixedly connected with a cap.

Preferably, posting reflecting marking on Anti-collision barrel outer surface.

Preferably, Anti-collision barrel outer surface generally yellow.

Preferably, Anti-collision barrel is provided with the opening for being used for injecting anti-flaming liquid.

After such scheme, the utility model possesses following advantage：

1. rotatable Anti-collision barrel is combined with rigidly fixing frame, it is ensured that structure has certain rigidity, while but also with certain Buffering energy-absorbing ability；

2. anti-flaming liquid is filled in Anti-collision barrel can prevent from causing vehicle burning with guardrail friction after Vehicular impact or explode, prevent Hitting the opening design of bucket can make equipment conveying installation more easily convenient；

3. the different structure designs of fixture make it that it possesses certain rigid above and below fixed mount, there is certain change again Shape pooling feature；

4. the combination of yellow Anti-collision barrel and reflecting strips can make Anti-collision barrel have more obvious visual effect, Vehicular impact is reduced The possibility of guardrail.

Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

Disclosed in the utility model is a kind of cushion guardail, as Figure 1-4, is preferable implementation of the present utility model Example, the cushion guardail is made up of fixed mount 1 and at least one column 2, and column 2 is fixedly connected with fixed mount 1, and fixed mount 1 is with standing Post 2 is similar to the common guardrail commonly used on current highway, is typically made up of rigid material, to ensure the firm of this cushion guardail Degree.Column 2 is fixed on fixed mount 1 in the form of length is spaced apart, and can be interlocked using one is long and the other is short（Such as Fig. 1）Or one The different distribution modes such as long two short delivery mistakes, can specifically be determined according to different sections of highway to rigid demand to its distribution mode. Long column 2 is inserted into ground after being interfixed with fixed mount 1, and to carry out standing support to whole guardrail, short column hangs It is empty.Rotatable Anti-collision barrel 21 is arranged with outside column 2, buffering energy-absorbing function is mainly played, when Vehicular impact is to guardrail, huge punching Power drives Anti-collision barrel 21 to start to rotate, and vehicle energy effectively is converted into the energy that anti-turning barrel 21 is rotated, and guide vehicle along public affairs Road trend is slided forward, is further driven to subsequent several Anti-collision barrels 21 and is rotated, further absorbs automobile kinetic energy.The anticollision of socket Bucket 21 uses hollow design, and on the one hand its bucket increases device inertia to increase the kinetic energy of its absorption built with anti-flaming liquid, another Aspect, the anti-flaming liquid for overflowing or blasting can be prevented effectively from scene of an automobile accident generation fire.

Wherein, the upper fixing element 11 and lower fixture 12 that fixed mount 1 is made up of rigid material are constituted, and can specifically be used Shoulder guard, lower fixture 12 is the tabular component with plane-parallel, and tabular component possesses certain transverse width due to it, because This has stronger rigidity, can avoid severing during big load Vehicular impact being evenly distributed with guardrail, tabular component and is available for column 2 The fixing hole 13 of insertion, long column 2 is i.e. by inserting the fixing hole 13 and being further inserted into soil.Upper fixing element 11 is distribution Two strip members in the upper end both sides of column 2, the strip member that metal is made is so that guardrail has necessarily variable on the whole Shape, realizes deformation energy-absorbing.Upper fixing element 11 is connected by extending transversely through the upper pin 31 of two strip members and being fixed with column 2 Connect.To ensure the stability of guardrail, design upper fixing element 11 is parallel to each other with lower fixture 12 in same vertical plane, while on Two bar shaped Components Shapes, quality of fixture 11 are suitable.The upper end of column 2 is also fixedly connected with a cap 22, to prevent in vehicle When being collided with guardrail, guardrail entirety is left in impact to column 2 upwards with Anti-collision barrel 21, causes the work of guardrail energy-absorbing buffering With decrease.Column 2 is further fixed by the lower bearing pin 32 through the lower both sides of fixture 12, upper pin 31 and lower bearing pin 32 It is longitudinally-aligned.Fixed mount 1 and column 2 as cushion guardail rigid element, it is ensured that guardrail by when shock not The vehicle that can be broken and hit the guardrail will not leave road surface.

The outer surface of the Anti-collision barrel 21 generally yellow being arranged outside column 2, can on bucket outer surface with higher identification Reflecting marking 23 is posted, to lift guardrail night identification.There is a fixed gap between Anti-collision barrel 21 and column 2 and fixed mount 1, Anti-collision barrel 21 is preferably rotated around column 2.Typically there is certain angle of impingement when vehicle and guardrail shock, Anti-collision barrel 21 Preferable slide-and-guide can be carried out to vehicle by rotating, reached by extending the collision time of vehicle and guardrail mitigation vehicle with The damage of guardrail.The kinetic energy that guardrail absorbs can also reduce destruction dynamics of the vehicle to guardrail, and then reduce impact to occupant The injury caused.Meanwhile, Anti-collision barrel 21 is made of semi-rigid material, and internal is hollow-core construction, with certain deformation buffer Space.The inside of Anti-collision barrel 21 can be equipped with anti-flaming liquid, for example, can inject a large amount of water, cause Anti-collision barrel 21 when impact is sufficiently large When deformation even ruptures, the water of spilling can be prevented because high-speed friction causes vehicle fire.

In addition, Anti-collision barrel 21 is also provided with the opening for injecting anti-flaming liquid, needed when installing guardrail to Anti-collision barrel 21 when being transported, and Anti-collision barrel 21 can be allowed to be in hollow state, can so greatly reduce cost of transportation, reduces project installation difficult Degree, to be installed finish injects fire-retardant water into bucket again.
