Abstract
The utility model provides a device for preventing kart knocks into back and pierces card, freight train afterbody, it mainly is that the current kart of solution is too fast because of speed, easily pierces its afterbody with large -scale card, when the freight train knocks into the back, causes technical problem such as serious accident. Its technical scheme main points are: it includes the pivot and installs and changeing epaxial insurance crash barrier that two insurance crash barrier tail ends pass through the hydraulic cushion system - device and connect formation triangle -shaped support. It prevents that kart from knocking into the back when being used for arousing the rear -end collision because of rear kart at the excessive speed because of speed to pierce card, freight train afterbody.
Description
Technical field
The utility model device, is that one prevents miniature car because of excessive velocities, and pierces the device of large-scale card, truck tail.
Background technology
Road Transportation industry, while promotion socio-economic development, also brings serious safety problem.In road traffic accident, the accident proportion caused by rear-end collision is the highest, the property damage caused and personal casualty account for 60% of total damage, in the middle of numerous traffic accidents, have a kind of traffic accident can say compared with other accidents more to make us feeling distressed, be exactly that small passenger car directly creeps into truck tail, cause driver and crew dead.According to related data statistics, the small passenger car truck accident that knocks into the back accounts for 50% of traffic accident of knocking into the back, and lethal ratio is four times that car and other vehicles collide lethal ratio.The accident that small passenger car pierces at the bottom of truck car is all of common occurrence except the subjective factor of troublemaker in various places, the geometric shape size of truck and small passenger car and the difference of version, is also the key factor of seriousness of causing the accident.
Because hollow below the crossbeam of high capacity waggon rear portion, in accident, small passenger car headstock very easily pierces the rear lower space of lorry, in addition two car mass discrepancies are large, small passenger car speed is fast, and knock into the back in process, front windshield and the roof front portion of car directly can bump against truck tail.
The height of a small passenger car is at 70 centimetres to 80 centimetres, and truck afterbody distance ground is more than 100 centimetres, and this diff-H is just the height of driver head and chest.Although the crash barrier of lorry can only play buffer action to a certain extent when there is rear-end collision, but but can prevent small passenger car from creeping into automobile tail, if lorry does not have crash barrier, once knock into the back, small passenger car will creep into truck chassis, and driver head is stuck between compartment and sedan seat, and bearing circle then withstands on front, driver is easy to be stuck, and probability of surviving is very low.
Meanwhile, the safety air bag touch device of most small passenger car is all before headstock, and only have when small passenger car front portion is subject to clashing into, safety air bag just can be touched ejection.If the whole predecessor of car directly enters into bottom lorry, safety air bag cannot start again, and so, the personal safety being sitting in the driver and crew of small passenger car dress circle then loses guarantee completely.
Its tangible small passenger car knocks into the back in the accident of truck, and a lot of chaufeur can avoid death, but because part truck is not according to relevant criterion installation guard rail, small passenger car directly pierces truck afterbody, causes dolly autoprotection systemic-function to completely lose.Although the security anti-collision bar of truck tail, unobtrusively very important, is but prevent from small passenger car from knocking into the back to creep into the necessary devices that truck tail causes injures and deaths.
Summary of the invention
The purpose of this utility model is to provide a kind of when passenger and freight car travels on a highway, prevents rear miniature car from causing the even dead miniature car that prevents of rear-end collision knock into the back and pierce the device of card, truck tail because of excessive velocities.
The utility model solves the technical scheme that its technical matters adopts: it comprises rotating shaft and is arranged on the security anti-collision hurdle in rotating shaft, and two security anti-collision hurdle tail ends are connected to form triangular supports by hydraulic damping device.
Security anti-collision hurdle tail end is provided with installation hanger.
Hydraulic damping device is provided with 2 hydraulic oil pipes.
Security anti-collision hurdle adopts high strength steel to make.
Described security anti-collision hurdle offers the tri-angle-holed of alternative arrangement.
The beneficial effects of the utility model are: structure is simple, only a set of hydraulic damping device, crashproof insurance hurdle, and hanger erecting device forms.When miniature car knocks into the back large-scale card, lorry, hydraulic damping device dispersion dominating impact power, with insurance hurdle, hanger erecting device is connected to form a very stable triangular structure, can effectively prevent miniature car from piercing card goods afterbody.And existing card, lorry safety device do not have this design, and stability is very poor, without shock absorber, more cannot bear powerful dynamics and impact.The utility model, when card lorry carries out unloading process, shrinks by hydraulic pipe, can not hinder its carrying out of unloading.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further details.
As shown in Figure 1 to Figure 4, the utility model is arranged on the afterbody of card, lorry by hanger 3, and hydraulic damping device 6 supports crashproof insurance hurdle 5 and forms triangular supports structure, to increase its stability.When miniature car knocks into the back large-scale card, lorry because of unavoidable drag factor, first headstock clashes into security anti-collision hurdle 5, and dolly is clashed, and first triggers the air bag for protection system of miniature car inside, protects vehicle crew of knocking into the back.Clash and make security anti-collision hurdle 5 produce slight deformation; hydraulic damping device 6 supports whole dynamics and impacts, and impulsive force is carried out buffering dispersion, keeps the structure integrity of this utility model; thus effectively prevent wear end collision of automobile from piercing card, truck tail, protect the life security of vehicle crew of knocking into the back.
Hydraulic oil pipe 1 can provide liquid to hydraulic damping device, supports the realization of its buffering dynamics effect.
It is also fixing that installation hanger 3 can help this utility model to be arranged on card, truck tail.
Rotating shaft 4 can be rotated, and security anti-collision hurdle 5 can be made to rotate and shrink, and helps card, lorry unloading process.
Security anti-collision hurdle 5 adopts high strength steel to make, and can bear powerful dynamics and impact; Described security anti-collision hurdle offers the tri-angle-holed of alternative arrangement, can effective disperses impact forces.
Hydraulic damping device 6 one aspect can cushion impulsive force when miniature car knocks into the back, and holding device structural integrity prevents automobile from piercing afterbody; Can shrink when card, lorry unloading on the other hand, not affect the use of card, lorry normal function.
