Description

Technical Field

[0001] The invention relates to the technical field of danger avoidance lanes, in particular to a danger avoidance lane for out-of-control vehicles on a highway. Background Art

[0002] The escape lane is a special lane added on the outside of the driving lane for vehicles with out-of-control speed (brake failure) to decelerate safely. The escape lane mainly consists of approach lanes, brake lanes, service lanes and auxiliary facilities (roadside guardrails, anti-collision facilities, rescue anchor bolts, emergency telephones, lighting, etc.).

[0003] At present, there are four types of escape lanes commonly used: up-ramp type, horizontal ramp type, down-ramp type and sand pile type. For highways, since out-of-control vehicles generally have high speeds, the use of up-ramp type, horizontal ramp type or down-ramp type requires the installation of a long braking lane, which not only occupies a large area and is difficult to construct, but also greatly increases the construction cost. Therefore, for highways, the escape lane often adopts the sand pile type.

[0004] The braking lane in the sand pile type escape lane uses gravel, sand and other materials laid inside the lane to increase the vehicle's driving resistance to achieve the purpose of deceleration and braking to avoid danger. However, this method causes the vehicle to be trapped in the gravel pool used for deceleration, and it is difficult to get out of the trap by itself. It needs to be rescued by a rescue vehicle, which will increase the rescue cost of the out-of-control vehicle. Summary of the invention

[0005] The purpose of the present invention is to provide a highway out-of-control vehicle escape lane, which is used to solve the problem that out-of-control vehicles are difficult to escape by themselves when highway escape lanes are used in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a highway out-of-control vehicle avoidance lane, comprising a ramp and a pool body connected to the rear end of the ramp, wherein a plurality of columns are respectively vertically fixed at the edges on both sides of the top surface of the ramp; the rubber roller is rotatably mounted on the columns; the hydraulic wave deceleration mechanism comprises a plurality of support slats arranged longitudinally on the top of the pool body and extending transversely respectively, and a hydraulic cylinder having a piston cylinder bottom end fixed to the bottom surface of the inner cavity of the pool body and a piston rod top end fixed to the bottom surface of the support slats; the hydraulic pump room is arranged on a side of the pool body away from the main road of the highway, and a hydraulic oil pump system is provided in the hydraulic pump room; the hydraulic pipeline is used as a hydraulic oil channel between the hydraulic oil cylinder and the hydraulic oil pump system in the hydraulic pump room.

[0007] Preferably, a pad is fixedly attached to the bottom surface of the support slat, and two ends of the bottom surface of the pad are respectively fixedly connected to the top end of the piston rod of the corresponding hydraulic cylinder.

[0008] Preferably, the rubber roller comprises a metal hub rotatably mounted on the column and a rubber rim fixedly mounted on the periphery of the metal hub.

[0009] Preferably, the ramp includes a slope starting section and a connecting slope section connected to the rear end of the slope starting section, and the slope of the connecting slope section is greater than the slope of the slope starting section.

[0010] Preferably, a service lane is provided on the side of the approach road and the pool body away from the main road of the highway.

[0011] Preferably, the service lane includes a slope lane arranged on one side of the slope starting section and a horizontal lane connected to the rear end of the slope lane and arranged on one side of the pool body.

[0012] Preferably, the approach road and the pool body are provided with guardrails on the side close to the main road of the highway and the service lane is provided with guardrails on the side away from the main road of the highway.

[0013] Preferably, the rear ends of the pool body and the service lane are fixedly connected with an end retaining wall.

[0014] Preferably, the front wall of the end retaining wall is wrapped with a flexible buffer material.

[0015] Preferably, a pressure sensor is installed between the support slat and the pad, and the pressure sensor is connected to the solenoid valve for controlling the extension and retraction of the hydraulic cylinder via a PLC control module signal.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention relates to a highway out-of-control vehicle avoidance lane, which is provided with a hydraulic wave deceleration mechanism. When the out-of-control vehicle enters the top of the pool, the hydraulic cylinders at different positions near the wheels lift the support slats installed above the out-of-control vehicle to different heights, so that the wheels are stuck by the wave-shaped support slats, thereby achieving the braking of the out-of-control vehicle and achieving the effect of avoiding danger.

[0018] 2. The hydraulic wave deceleration mechanism in the escape lane of an out-of-control vehicle on a highway involved in the present invention can control the piston rod of the hydraulic cylinder to descend so that the raised support slats fall down and restore the initial height, so that the support slats support a flat support surface, thereby facilitating the out-of-control vehicle to drive out of the escape lane after repair, greatly reducing the cost of the vehicle's escape.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-4 The present invention provides a technical solution, a highway out-of-control vehicle escape lane, comprising an approach road 1 and a pool body 2 connected to the rear end of the approach road 1. The approach road 1 comprises a ramp section 1.1 and a connecting slope section 1.2 connected to the rear end of the ramp section 1.1, and the slope of the connecting slope section 1.2 is greater than the slope of the ramp section 1.1.

[0035] A plurality of columns 4 are vertically fixed to the edges of both sides of the top surface of the ramp 1, and a rubber roller 5 is rotatably mounted on the columns 4. The rubber roller 5 includes a metal hub 5.1 rotatably mounted on the column 4 and a rubber rim 5.2 fixedly mounted on the outer periphery of the metal hub 5.1.

[0036] The hydraulic wave deceleration mechanism 6 comprises a plurality of support slats 6.2 arranged longitudinally on the top of the pool body 2 and extending transversely respectively, and a hydraulic oil cylinder 6.1 whose piston cylinder bottom end is fixed to the bottom surface of the inner cavity of the pool body 2 and whose piston rod top end is fixed to the bottom surface of the support slats 6.2. Among them, a pad 6.3 is fixedly attached to the bottom surface of the support slat 6.2, and the two ends of the bottom surface of the pad 6.3 are respectively fixedly connected to the top end of the piston rod of the corresponding hydraulic oil cylinder 6.1.

[0037] The hydraulic pump room 9 is located on the side of the tank body 2 away from the main road of the expressway, and a hydraulic oil pump system is installed in the hydraulic pump room 9; the hydraulic pipeline 10 is used as a hydraulic oil channel between the hydraulic oil cylinder 6.1 and the hydraulic oil pump system in the hydraulic pump room 9. In addition, a pressure sensor is installed between the support slat 6.2 and the pad 6.3, and the pressure sensor is connected to the solenoid valve used to control the extension and retraction of the hydraulic oil cylinder 6.1 through the signal of the PLC control module.

[0038] A service lane 3 is provided on the side of the approach road 1 and the tank body 2 away from the main road of the highway. The service lane 3 includes a ramp lane 3.1 provided on one side of the slope section 1.1 and a horizontal lane 3.2 connected to the rear end of the ramp lane 3.1 and provided on one side of the tank body 2.

[0039] Guardrails 7 are provided on the side of the approach road 1 and the pool body 2 close to the main road of the expressway and on the side of the service lane 3 away from the main road of the expressway.

[0040] The rear ends of the pool body 2 and the service lane 3 are fixedly connected with an end retaining wall 8. The front wall of the end retaining wall 8 is wrapped with a flexible buffer material.

[0041] In summary, the escape lane is generally arranged outside the emergency lane of the highway main road. When in use, the out-of-control vehicle leaves the highway main road and drives towards the approach road 1. When the vehicle collides at this time, it will directly hit the rubber roller 5, which will not only cushion the impact of the vehicle and reduce the degree of damage to the vehicle, but also guide the vehicle. When the vehicle continues to drive under the guidance of the rubber roller 5, it will enter the braking lane (i.e., the plane supported by the support strip 6.2).

[0042] When the vehicle drives onto the support slats 6.2 above the tank 2, the hydraulic pump system in the hydraulic pump room 9 delivers hydraulic oil to the hydraulic cylinders 6.1 in front and behind the front wheels of the vehicle through the hydraulic pipes 10. After the action of the hydraulic valve, the piston rods in the hydraulic cylinders 6.1 at different positions extend to different lengths, and the piston rods lift the support slats 6.2 above through the pads 6.3. The different extension lengths of the piston rods make the support slats 6.2 at different heights, arranged in a wave shape at the front wheel. At this time, the front wheel is at the lowest position of the wave and can be stuck by the front and rear raised support slats 6.2; the state of the support slats 6.2 at the rear wheel is consistent with that of the front wheel, and the front and rear wheels of the vehicle are both stuck to achieve a braking effect.

[0043] When the out-of-control vehicle stops, the piston rod in the hydraulic cylinder 6.1 is controlled to fall, so that the raised support strips 6.2 fall back to their original height, and the vehicle is on a flat road. At this time, the vehicle can reverse out of the escape lane without using a crane or road rescue vehicle to help the out-of-control vehicle escape, which reduces costs and saves time.

[0044] In addition, the service lane 3 is used for rescue vehicles to provide emergency rescue activities for out-of-control vehicles, which provides a guarantee for timely solving the problem of out-of-control vehicles and saves time. If the out-of-control vehicle fails to successfully achieve braking through the hydraulic wave deceleration mechanism 6 of the braking lane, the end retaining wall 8 facility can intercept the out-of-control vehicle in time and finally stop the vehicle to prevent the vehicle from running out of the escape lane. That is, the setting of the guardrail 7 and the end retaining wall 8 is used to prevent the out-of-control vehicle from running out of the escape lane and causing greater casualties.
