Abstract
The utility model discloses a combined emergency roadway, which comprises gravel embankment and a net blocking device. Wherein the gravel embankment is paved with non-graded gravels with basic even particle size and the net blocking device comprises fencing nets, force transmission cables and damping devices. The fencing nets consist of transverse and longitudinal cables. Both ends of the fencing nets are provided with force transmission cables, which wind on the damping devices. The damping devices on both sides of the fencing nets comprise a roller for winding cables, a force transmission shaft, a bearing and bearing saddle, a damping stick, a material collecting barrel, damping material and a ground connecting device. When the combined emergency roadway is used, the vehicle crushes on the gravel embankment first, the wheels and the embankment can produce rolling resistance to force the vehicle decelerate and collide on the net blocking device and the vehicle can bring along the fencing net to run forward. The impulsion force is transmitted to the damping devices on both sides via the fencing nets and the force transmission cables. The vehicle stops, under the function of the blocking devices, is a combination of the blocking resistance and the rolling resistance, to counteract the function of failure of vehicle braking.

Technical field
The utility model relates to a kind of combined type emergency lane, is used for a kind of safety device that the mountain highway emergency lane need be tackled the brake failure vehicle.
Background technology
Etesian traffic accident is all in rapid increase, and especially highway accident more very.Wherein because the malfunctioning accident of vehicle brake is all occupied certain ratio every year.Emergency lane need be built in many places to mountain highway owing to the restriction of geographical conditions, has built emergency lane and has brought into play the effect that alleviates or avoid accident preferably.But because the restriction in geographical position, a lot of places can't be provided with emergency lane; The emergency lane curtailment that perhaps can build, the vehicle existence bigger accident potential higher for runaway speed; Perhaps can build, cost is also too high, and since in the past the rubble emergency lane be the purpose that provides resistance to rolling to realize interception car to wheel by roadbed, when resistance to rolling is excessive, cause the disconnection of wheel shaft and compartment easily, cause second accident.So develop a kind of simple and practical, cheap, protective capacities strong, car body and driver and conductor are damaged the society need that little emergency lane becomes traffic safety.
Along with China's rapid economy development, road network density also progressively increased when road quality classification improved, and the raising of social traffic safety consciousness makes highway emergency lane quantity constantly increase.So, the emergency lane that a kind of protective capacities is strong, cheap, structure is attractive in appearance is provided, can satisfy safe, attractive in appearance needs, simultaneously, because low universal use of being more convenient for of cost.
The utility model content
The purpose of this utility model provides a kind of combined type emergency lane, this combined type emergency lane can effectively be tackled the brake failure vehicle in short length, save roadbed length 30% to 50%, and vehicle stressed be the resistance to rolling of wheel and roadbed and the interception resistance acting in conjunction that blocking apparatus provides vehicle body, effectively reduce car body and destroy and casualties, also can carry out technological improvement with regard to existing rubble emergency lane and improve its protective capacities.After laying, its combination can realize the vehicle target that safety is stopped in designed distance.
For realizing above-mentioned target, the utility model adopts following technical scheme: the combined type emergency lane, comprise rubble roadbed and rete cord blocking apparatus, wherein the rubble roadbed is laid by the basic rubble uniformly of particle diameter and is formed, and the rete cord blocking apparatus is made of the power transmission rope and the damping unit of protective screening and both sides.Described protective screening is made of horizontal, vertical connecting strand, and protective screening is connected by the power transmission rope with damping unit.
Described combined type emergency lane has certain gradient, can according to specific geographic environment be set to upward slope, flat slope, descending one of them, or applied in any combination.
Described rubble roadbed can adopt rubble or cobble one of them.
Described damping unit can be available damping units such as friction-type damping unit, fluid pressure type damping unit, magnetic-type damping unit or brake gear.
Power transmission rope on the described damping unit can be available ropes such as wire rope, nylon rope, common rope.
Horizontal, the vertical connecting strand of described formation protective screening can be that wire rope, nylon rope are one kind of.
Described protective screening is hung by the bracing frame concordant with net and is stood on the road surface.
This above-mentioned damping unit is made up of rope woolding cylinder, force transmission shaft, bearing and bearing support, damper bar, material collecting barrel, damping material and ground linkage, splendid attire damping material in the material collecting barrel, be fixedly installed on the both sides, road surface, bearing and bearing support are separately fixed in material collecting barrel central authorities top and the material collecting barrel by the ground linkage, force transmission shaft is arranged on the bearing, damper bar is horizontally installed on the interior position of material collecting barrel of force transmission shaft, the top of force transmission shaft is provided with the rope woolding cylinder, described power transmission rope is wrapped on the rope woolding cylinder, and damper bar is arranged in the damping material of material collecting barrel.
When being blocked vehicle and entering emergency lane, wheel and roadbed produce resistance to rolling forces vehicle tentatively to slow down, touch the rete cord blocking apparatus then, vehicle drives protective screening and moves ahead, impact force passes to the both sides damping unit by protective screening and power transmission rope, vehicle is subjected to the interception drag effect of damping unit, promptly tackles resistance and resistance to rolling acting in conjunction and offsets the vehicle collision energy, stops until vehicle.
The utility model structure design is simple, reasonable, damping unit is set to different safety class according to actual needs, be that energy dissipating quantity can be designed as different ranks, build the length requirement design, reach the purpose that makes the high speed errant vehicle slow down and finally stop according to regional emergency lane.And can the length of rubble roadbed and the group number of protective screening be set according to the protection energy grade, form the protective equipment of different safety class, and it be simple and easy to construct, with low cost, good looking appearance, real is the significant emergency lane of a kind of interception result.
