Description
Technical field
The present invention relates to expressway ramp fields, and in particular to a kind of expressway ramp mouth protecting device.
Background technique
With the continuous development of China's economy, highway to build speed also higher and higher, China's most area is real
The perforation of highway is showed.Due to being gradually increased for China's people's quality of life, private car quantity gradually rises, and 2015 complete
State's automobile volume of production and marketing reaches 25,000,000, and 2016 have doubled.The increase of automobile usage amount necessarily drives highway vehicle
The increase of flow, during festivals or holidays especially, vehicle flowrate will be relative to being usually higher by 10%~30%, and accident rate is also substantially
Degree rises.
According to incompletely statistics, 30% traffic accident occurs in ramp mouth, therefore prepares in expressway ramp mouth
Protective device is necessary, and the protective device being commonly used at present is Anti-collision barrel, but is empty or be put into foam because it is internal
Etc. soft substance, it is easy to happen deformation when being hit, protects the less effective of the wounded, is especially hit by large-sized truck
It hits, effect is worse, fails to play the role of to protect the wounded well.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of expressway ramp mouth protecting device, not when being hit
Easy deformation, anti-collision energy absorption effect is good, and material is recyclable, avoids the wasting of resources.
To achieve the goals above, the present invention uses following technical scheme：A kind of expressway ramp mouth protecting device, packet
Anti-collision barrel is included, the engaging lug parallel with Anti-collision barrel upper surface, the Anti-collision barrel packet are disposed on the side wall of the Anti-collision barrel
The first barrel of wall for including bottom plate and upwardly extending along its periphery, the bucket that first barrel of wall and bottom plate enclose are intracavitary filled with foamed aluminium
Layer.
Bring of the present invention has the beneficial effect that：The present invention is by the way that in the intracavitary filled and process aluminium layer of bucket, foamed aluminium layer has excellent
Different foamed aluminium has excellent physical property, chemical property, mechanical property and can be recycled, by the intracavitary setting foam of bucket
Aluminium layer, protective bucket has better damping performance and impact energy absorptivity when being hit, and is not susceptible to by shock
Deformation is usually also caning absorb noise, is mitigating the noise pollution in city, Anti-collision barrel side wall is disposed with engaging lug, can be according to reality
Demand connect multiple Anti-collision barrels, it is simple by engaging lug connection and effect is good.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 uses schematic diagram for of the invention；
Specific embodiment
The present invention is described in detail by 1-2 with reference to the accompanying drawing.
As shown in Figure 1, a kind of expressway ramp mouth protecting device, including Anti-collision barrel 1, the side wall of the Anti-collision barrel 1
On be disposed with the engaging lug 11 parallel with 1 upper surface of Anti-collision barrel, the Anti-collision barrel 1 includes bottom plate 12 and prolongs upwards along its periphery
The first barrel of wall 13 stretched, the bucket that first barrel of wall 13 and bottom plate 12 enclose are intracavitary filled with foamed aluminium layer 14.By intracavitary in bucket
Foamed aluminium layer is set, and protective bucket has better damping performance and impact energy absorptivity when being hit, and is hit
It is not susceptible to deformation, noise is usually also being can absorb, is mitigating the noise pollution in city.
As shown in Figure 2, it is preferred that the bottom plate 12 upwardly extends second barrel of wall with first barrel of 13 arranged adjacent of wall
15, the bucket enclosed between second barrel of wall 15 and first barrel of wall 13 is intracavitary to be filled with foamed aluminium layer 14.When receiving shock, first
Bucket wall 13 is impacted at first, and impact kinetic energy passes to the foamed aluminium layer 14 of first barrel of 13 inner cavity of wall, is buffered by foamed aluminium layer 14
It absorbs, passes to after second barrel of wall 15 and successively impact 14, second barrels of first barrel of wall 13, foamed aluminium layer walls 15 again through air cushion,
Buffering, the effect of energy-absorbing are greatly improved, Anti-collision barrel outer wall is provided with reflective tape, plays a warning role to a certain extent.
Further, first barrel of wall of the Anti-collision barrel 1,13, second barrels of walls 15 are that multi-layer fiber enhances composite material system
Make, the base material be modified polyurethane material, modified polypropene it is one or more, selecting has certain anticollision effect
The material further injury in mitigation accident.
Further, the modified polyurethane material method of modifying is as follows：Under nitrogen protection, dihydroxymethyl third is added
Acid, glycerine, polyneopentyl glycol adipate, deionized water, be heated to 50 DEG C be stirred to react after, be down to room temperature be added chain extender
The reaction was continued obtains modified polyurethane prepolymer for quinhydrones one or two (mono- ethoxy of β)；At a constant temperature, crosslinking agent isophorone is added
Diisocyanate is stirred to react, and the modified polyurethane elastomer is made in cooling.By the way that polyurethane material is modified, further
The function and effect of polyurethane are promoted, so that bucket wall obtained is anti-oxidant, wear-resisting property is good, there is certain heat insulation, even if
Being exposed to outdoor can also use for a long time, shorten maintenance time, alleviate cost.
Further, the modified polypropene includes 40~60 parts of polypropylene, 10~20 parts of cyclophosphamide polymer, hydrogen
10~20 parts of magnesia, 0.8~1.2 part of rare-earth stabilizer, 2~4 parts of ethyl alcohol.Modified polypropylene has good flexibility
And anti-flammability can play good flame retardant effect in case of fire when by accident, and can promote anti-collision energy absorption effect.
Further, through-hole 112 is offered on the engaging lug 11, offers fracture 113 on the engaging lug 11.
As shown in Fig. 2, the described engaging lug height is arranged, when need anticollision ring road mouth it is longer or wider when, it is necessary to it is anti-at one
The back and forth or left and right for hitting bucket connects another, and production can be selected to have particular number of engaging lug to meet reality according to actual needs
Border needs, and is tightened by matched screw across through-hole and is fixedly connected with ear, and when disassembled, only need to unscrew screw can be from incision position
Anti-collision barrel is taken out, convenient and efficient, the Anti-collision barrel is integrally formed.
Basic principles and main features and the features of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement is both fallen in the range of claimed invention.The scope of protection of present invention is by appended claims
And its equivalent thereof.
