Abstract
The invention discloses a collision energy absorption device of an emergency lane. The collision energy absorption device mainly comprises a fastened barrier, constraint enclosing walls and an energy absorption baffle, wherein the energy absorption baffle has the function of absorbing energy, the constraint enclosing walls can prevent vehicles from tilting, and the fastened barrier can stop vehicles out of control, so that the vehicles cannot continue to go forward . A set of collision energy absorption device is mounted at the tail end of the emergency lane, when a vehicle runs down a long slope, the brake of the vehicle is invalid, and the vehicle is forced to run into the emergency lane, so that vehicles running at different speeds can be guaranteed to be braked by a braking bed of the emergency lane in a limited distance at first, and then are forced to pass through the collision energy absorption device mounted at the tail end of the emergency lane, and finally, the vehicles stop safely and reliably.
Description
Technical field
The invention belongs to road safety protective device, particularly relate to a kind of emergency lane collision energy-absorbing device.
Background technology
There is in mountain area the track of some lower long slopes often to cause the brake failure of some vehicles, for this reason, have special emergency lane.The braking bed of emergency lane can make vehicle compulsory brake and stop, however emergency lane be subject to place restriction be often difficult to enough braking distances.Emergency lane collision energy-absorbing device is for the protection of the vehicle being forced into emergency lane because of brake fade.Existing apparatus generally adopts waste rubber tire, gather materials heap and energy dissipating bucket, and these energy-dissipating installations generally exist energy-absorbing effect instability, and energy absorption performance is steady not, and may produce excessive collision impact.Can be there is uncontrollable material and disperse in vehicle and energy-absorbing facility collision rift, may cause with the secondary collision of vehicle and threaten vehicle and driver and conductor's safety; Meanwhile, in collision, the state of vehicle is without constraint, likely turns on one's side, and causes major accident.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple and practical, safe and reliable emergency lane collision energy-absorbing device.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: emergency lane collision energy-absorbing device, mainly comprise firm obstacle, constraint enclosure wall and energy-absorbing baffle plate, firm obstacle is positioned at the end of device, Constrained enclosure wall is built in firm obstacle both sides, be provided with energy-absorbing baffle plate between two constraint enclosure walls, energy-absorbing baffle plate is connected damping oil cylinder through rope with guide wheel.
Firm obstacle is firmly connected with ground.
Firm obstacle collision side is bolted energy-absorbing watt.
Energy-absorbing watt surperficial undulate.
Energy-absorbing watt high 1.5m.
Respectively there is a rope corner of energy-absorbing baffle plate, and every root rope connects a damping oil cylinder, also has some guide wheels between rope and oil cylinder.
For the problem of the existing energy absorption device poor effect of emergency lane braking distance finite sum, inventor has designed and produced a kind of emergency lane collision energy-absorbing device, and this device mainly comprises firm obstacle, constraint enclosure wall and energy-absorbing baffle plate.Wherein, energy-absorbing baffle plate plays energy-absorbing function, and constraint enclosure wall prevents vehicle lateral deviation, and firm obstacle blocks errant vehicle and avoids it to move on.At emergency lane end, a set of device is installed, when automobile lower long slope causes brake failure to be forced to sail emergency lane into, can ensure that different speed of a motor vehicle automobile is after the braking through emergency lane braking bed limited distance, again through the braking by force of the collision energy-absorbing device of end, final realization is stopped safely and reliably.

Detailed description of the invention
As shown in Figures 1 to 4, emergency lane collision energy-absorbing device of the present invention mainly comprises firm obstacle 1, constraint enclosure wall 3 and energy-absorbing baffle plate 4, and firm obstacle is positioned at the end of device and is firmly connected with ground; Firm obstacle collision side is bolted corrugated energy-absorbing watts 2, energy-absorbing watt high 1.5m; Constrained enclosure wall is built in firm obstacle both sides, and be provided with energy-absorbing baffle plate between two constraint enclosure walls, respectively there is a rope 6 corner of energy-absorbing baffle plate, and every root rope connects a damping oil cylinder 8, also has some guide wheels 7 between rope and oil cylinder.
Each component function
Firm obstacle is connected with ground secure rigid, can resist impact, block errant vehicle, effectively prevents the vehicle through energy-absorbing and constraint, prevents it from continuing to move forward.
Energy-absorbing watt can protect firm obstacle, can play certain energy-absorbing function simultaneously; Energy-absorbing watt covering to obstacle 1.5m At The Height by ground, substantially can be contained the headstock collision scope of lorry to general dolly preferably, meet making contact needs.
Constraint enclosure wall can retrain the vehicle entered, and prevents it from lateral deviation occurring, and it can support and retrain the vehicle being about to occur to roll, and makes it keep direction of advance, supports it simultaneously and keeps vertically preventing from rolling.
Energy-absorbing baffle plate is positioned at emergency lane collision energy-absorbing device foremost, its size contains the cross section of whole device portal just, baffle plate there are four bridle ports, be connected with four ropes 6, every bar rope then connects a damping oil cylinder, between rope and oil cylinder, also have some guide wheels, for guided constraint rope, make it to move along predetermined direction.During collision, baffle plate comes in contact with headstock and moves with vehicle, then pulls connected rope, pulls the piston of damping oil cylinder through guide wheel, under the effect of damping oil cylinder, finally consume the energy of vehicle.
