The both ends of continuous roller, roller are sprocket wheel, and several roller both ends are respectively arranged with a chain, and chain is around on several sprocket wheels；
The gradient section includes benchmark ramp, and the downside in benchmark ramp is arranged towards braking section, has lifting ramp, institute on benchmark ramp
The one end for stating lifting ramp is articulated with the downside in benchmark ramp, and the two sides for going up and down ramp are respectively equipped with the traction of a connection chain
Bar, draw bar both ends are hinged with chain and lifting ramp respectively, have extension between the benchmark ramp and braking section；It is described
Benchmark ramp built-in piston chamber, the accent of plunger shaft are located at the plane in benchmark ramp, have piston in plunger shaft, have on piston
Piston rod, the end that piston rod is located at outside plunger shaft are hinged with bearing plate, and the bearing plate is fixed to be attached at lifting ramp bottom,
The plunger shaft bottom is provided with Non-return air valve and exhaust passage, and gas enters plunger shaft from Non-return air valve from the external world, and exhaust is logical
Road is artificial opening and closing.
As a further preferred solution, changeover portion is provided between two draw bars, the changeover portion direction is slowed down
The side of section is chain row, and the end of chain row is fixed on the chain of two sides.
As a further preferred solution, be wound with crawler belt outside several rollers, the creeper tread on crawler belt respectively with
The roller of corresponding position is fixedly connected, and track surface has anti-skid chequer.
As a further preferred solution, changeover portion is provided between two draw bars, the changeover portion direction is slowed down
The side of section is chain row, and the end of chain row is fixed on crawler belt.
As a further preferred solution, the other end in the lifting ramp, which is equipped with, collides air bag.
In the present invention, tire can drive roller 21, pull draw bar 33, and lifting ramp 32 is driven to rise, and speed is bigger, rises
It is bigger that descending grade road 32 rises angle.
Structure is simple in the present invention, and compared to more traditional emergency lane, the space for needing to utilize is smaller, is suitable for more
Landform guarantees that more dangerous ways can also have emergency lane；Also, the slope in lifting ramp can be changed according to the size of speed
Road angle can also have extraordinary braking effect to vehicle out of control under fast state, also be avoided that vehicle goes out hedging vehicle
Road.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
A kind of emergency lane automatically adjusting the gradient, including boot segment 1, braking section 2 and gradient section 3；The braking section 2 wraps
Several continuous rollers 21 are included, the both ends of roller 21 are sprocket wheel 22, and several 21 both ends of roller are respectively arranged with a chain 23, chain
Item 23 is around on several sprocket wheels 22；The gradient section 3 includes benchmark ramp 31, and the downside in benchmark ramp 31 is set towards braking section 2
It sets, there is lifting ramp 32 on benchmark ramp 31, the one end in the lifting ramp 32 is articulated with the downside in benchmark ramp 31, lifting
The two sides in ramp 32 are respectively equipped with the draw bar 33 of a connection chain 23,33 both ends of draw bar respectively with chain 23 and lifting slope
Road 32 is hinged, has extension 4 between the benchmark ramp 31 and braking section 2；The 31 built-in piston chamber 34 of benchmark ramp, it is living
The accent of plug chamber 34 is located at the plane in benchmark ramp 31, has piston 35 in plunger shaft 34, has piston rod 36 on piston 35, living
The end that stopper rod 36 is located at outside plunger shaft 34 is hinged with bearing plate 37, and the bearing plate 37 is fixed to be attached at lifting 32 bottom of ramp
Portion, 34 bottom of plunger shaft are provided with Non-return air valve 38 and exhaust passage 39, and gas enters from Non-return air valve 38 from the external world lives
Chamber 34 is filled in, exhaust passage 39 is artificial opening and closing.
When entering emergency lane to lose control of one's vehicle, by boot segment 1, into braking section 2, tire is contacted with roller 21, and more
Rolling force of the roller 21 by wheel, backscrolling drive chain 23 by sprocket wheel 22, and chain 23 drives draw bar 33, pulls
It goes up and down 32 relative datum ramp 31 of ramp to rise, changes ramp angles, after going up and down the promotion of ramp 32, pull on bearing plate 37
It rises, so that 34 inner piston 35 of plunger shaft be made to rise, ambient atmos enter from Non-return air valve 38, and lifting ramp 32, which is realized, to be fixed, when
When vehicle reaches gradient section 3, heavy grade gives bigger brake force, and speed is bigger, and chain 23 drives the speed of draw bar 33
Faster, then it is bigger to go up and down 32 promotion amplitude of ramp, better to the braking effect of vehicle, and after use, it is logical that exhaust is opened manually
Road 39, since gravity declines, lifting ramp 32 resets piston 35.
Under original state, when lifting ramp 32 attaches benchmark ramp 31, draw bar 33 is in the end of chain 23.
Due to the rotation yet restriction by lifting ramp 32 of roller 21, it not can be carried out unresisted rotation, guarantee vehicle
Certain road holding is kept, avoided to lose control of one's vehicle.
Pipeline, which is equipped with, on Non-return air valve 38 and exhaust passage 39 passes to the external world.
Embodiment one
Changeover portion 5 is provided between two draw bars 33, the changeover portion 5 is chain row 51 towards the side of braking section 2, and chain arranges 51
End be fixed on the chain 23 of two sides, vehicle can exercise on changeover portion 5, avoid between braking section 2 and gradient section 3
Wide-angle reduces vehicular impact power, improves safety, minimizes to the loss of car body.
Embodiment two
Crawler belt 24 is wound with outside several rollers 21, the creeper tread on crawler belt 24 is fixedly connected with the roller of corresponding position 21 respectively,
24 surface of crawler belt has anti-skid chequer, the setting of crawler belt 24, and the contact surface that can increase vehicle tyre and braking section 2 connects, and improves steady
It is qualitative, avoid speed too fast, single roller 21 is by larger pulling force, and the problem of damaging, crawler belt 24 can be by the rolling of tire
Power is shared out equally on each roller 21.
Further, changeover portion 5 is provided between two draw bars 33, the side of changeover portion 5 towards the braking section 2 is
The end of chain row 51, chain row 51 are fixed on crawler belt 24.
When vehicle can finish entirely in lifting 32 uplink of ramp, impact force at this time is also very small, lifting ramp 32
The other end, which is equipped with, collides air bag 6, and lifting ramp 32 can be gone out to avoid vehicle by colliding air bag 6.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
