Description
Technical field
Blocked system the present invention relates to vehicle, and in particular to a kind of vehicle stops system.
Background technology
With the extensive development of highway in China system, the safety of vehicle and means of transportation turns into focus of attention.At present
Reflection is than more prominent and common be：The errant vehicle run on highway（Mechanical breakdown or other reasonses）Itself, and to public affairs
Road facility runs the threat of vehicle with other on road.
The measure for tackling this kind of traffic harm at present is subsection setup emergency danger-avoiding track, makes errant vehicle and main road point
Open, so as to reduce the threat to normal vehicle and means of transportation.
The countermeasure taken for above-mentioned harm serves certain effect, but there is obvious defect：It is emergent to keep away
Dangerous track expands expropriation of land scope；A large amount of excavations are needed before building；Need large-scale civil engineering, thus Emergency Vehicle Lane
Investment is millions of at least, at most up to ten million；The very long engineering time is additionally needed, it is very uneconomical；Mistake can not be completely secured
Control vehicle is stopped in the range of emergency danger-avoiding track, is occurring traffic accident so as to be damaged to errant vehicle and personnel
Afterwards, the repair of Emergency Vehicle Lane is extremely difficult, and time-consuming longer.
The content of the invention
System is stopped it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of vehicle, cost is lower,
It is short that it blocks shield better and maintenance time.
The purpose of the present invention is achieved through the following technical solutions：

Rope is all equipped with damping mechanism so that integral damping is better.
Further, described frictional force of the part with being formed at damping noose circle portion interfaces that links closely is less than arrester wires
Tensile fracture.The purpose of the design is to prevent arrester wires is pulled off from not triggering damping mechanism but.
Further, the line formed between the support stake is vertical with anxious emergency lane so that for just during Vehicular impact
Face is hit, the offer Intercepting effects of maximum dynamics.
Further, the end of the arrester wires with damping Suo Shouduan be connected by junction button, it is described damping rope end with
Fixed between spud pile by junction button.
Further, described support stake and spud pile are separately installed with drawing anchor, the lead of the drawing anchor and support
The Impact direction of stake and spud pile is on the contrary, the drawing anchor end is connected with flexible roof bolt, and the flexible roof bolt is embedded in underground.
Flexible roof bolt possesses certain buffer capacity, can allow to draw anchor to stretch to a certain extent, adds spud pile and support stake
Survival ability.
Further, the structure of described damping rope ferrule portion is annular or " ∞ " shape, and the number of turns is 1~3 circle.
