Description

Technical Field

[0001] The present invention belongs to the field of road engineering technology, and specifically relates to a new central dividing strip system for smart highways that can change the driving directions of several lanes in the middle according to the different traffic flow conditions of lanes on both sides, and can relieve traffic pressure and effectively improve road utilization while ensuring road driving safety. Background Art

[0002] In order to solve the problem of uneven two-way traffic capacity and congestion, tidal lanes have been enabled on some urban roads in China, but they are still not widely used on highways. The setting of tidal lanes on these existing roads requires instructions from corresponding traffic controllers, and the setting process is cumbersome and time-consuming, which increases the labor cost of road maintenance; in addition, the set tidal lanes lack guardrail isolation, which poses a safety hazard in actual use.

[0003] At the same time, the existing central divider of expressways is fixedly set in the middle of the road, and most of the national highways, provincial highways and other trunk networks are fixed with Beijing-style guardrails, zinc steel road guardrails, etc. at the central divider. However, this type of traditional guardrail lacks flexibility in use, and the product form and function are relatively simple. The defect of the central divider being immovable has caused a great obstacle to solving the problem of highway congestion. In addition, the existing mobile isolation fence generally adopts the method of overall translation, which affects the vehicle's traffic capacity during the movement process, and can only be used in urban roads, which does not meet the relevant specifications of expressways, such as: "Automatic Lane Change Guardrail" with announcement number CN107938557A and "A Tidal Lane Automatic Change Device for Intelligent Traffic" with announcement number CN110295558A. Therefore, it is necessary to improve the central separation method and device of the tidal lane in the prior art. Summary of the invention

[0004] The present invention aims to solve the above-mentioned problems and provides a new central dividing strip system for smart highways which can change the driving directions of several lanes in the middle according to the different traffic flow conditions of the lanes on both sides, thereby alleviating traffic pressure and effectively improving road utilization while ensuring road driving safety.

[0005] The technical solution adopted by the present invention is: the new central dividing strip system for smart highways includes several groups of isolation mechanisms located in the middle of the road, and is characterized in that: the isolation mechanism is composed of several continuously arranged lifting guardrails, the lifting guardrails are located in guardrail accommodating grooves below the road surface, and guardrail lifting pillars are respectively arranged below the two ends of the lifting guardrails; the guardrail lifting pillars include guardrail lifting column piles fixedly arranged below the road surface, and guardrail lifting column bodies are arranged inside the guardrail lifting column piles, and guardrail lifting telescopic rods are arranged between the guardrail lifting column bodies and the guardrail lifting column piles, and the lower end of the guardrail lifting telescopic rod is connected to the driving end of the guardrail lifting drive device; the two ends of the lifting guardrail are respectively connected to the upper ends of the guardrail lifting columns on the corresponding sides through column connectors.

[0006] A horizontally arranged guardrail protection cover is movably arranged above the lifting guardrail arranged inside the guardrail accommodating groove; the end of the guardrail protection cover is located in a cover groove arranged at the side of the upper opening of the guardrail accommodating groove, and a cover driving mechanism for opening and closing the guardrail protection cover is arranged in the cover groove. The closed guardrail protection cover is used to protect and shield the lifting guardrail of the lowered isolation mechanism, thereby facilitating the normal driving of vehicles when the number of forward lanes and reverse lanes on the road changes.

[0007] The upper end of the guardrail lifting column of the guardrail lifting support is provided with a working status indicator light, so as to distinguish various working states of the system through the indicator lights of different colors.

[0008] The lifting guardrails of the isolation mechanism are in the form of two rows of parallel arrangement, and between the two rows of lifting guardrails, there are several groups of anti-glare partitions arranged along the direction of vehicle travel. The anti-glare partitions arranged between the two rows of lifting guardrails can effectively block the lights of vehicles on the opposite lane, thereby improving the driving safety of vehicles.

[0009] The anti-glare partitions are located below the road surface, and anti-glare partition lifting pillars are respectively arranged below each group of anti-glare partitions, so that the anti-glare partitions are driven by the anti-glare partition lifting pillars to rise and fall accordingly with the rise and fall of the lifting guardrail.

[0010] The anti-glare board lifting pillar comprises an anti-glare board lifting column pile fixedly arranged below the road surface, an anti-glare board lifting column body is arranged inside the anti-glare board lifting column pile, and an anti-glare partition is arranged inside the anti-glare board lifting column body; an anti-glare board lifting telescopic rod is arranged between the anti-glare partition, the anti-glare board lifting column body and the anti-glare board lifting column pile, and the anti-glare board lifting telescopic rod is composed of a telescopic primary rod and a telescopic secondary rod, and the lower end of the anti-glare board lifting telescopic rod is connected to the driving end of the anti-glare board lifting driving device. The telescopic primary rod and the telescopic secondary rod of the anti-glare board lifting telescopic rod are used to drive the anti-glare board lifting column body in the anti-glare board lifting column pile and the anti-glare partition in the anti-glare board lifting column body to rise or fall in sequence and continuously, thereby increasing the telescopic height of the anti-glare partition and enhancing the use flexibility of the device.

[0011] The anti-glare partition is connected to the telescopic secondary rod of the anti-glare partition lifting telescopic rod through the anti-glare partition connecting fastener, so as to flexibly replace the anti-glare partition with different structures according to the specific use environment needs.

[0012] The upper outer sides of the anti-glare plate lifting columns of the anti-glare plate lifting pillars are respectively provided with guide lighting lamps to play the role of indication and lighting.

[0013] The guardrail lifting pillars at the ends of two adjacent groups of lifting guardrails of the isolation mechanism are detachably connected via guardrail pillar connecting pieces, so that each group of lifting guardrails of the isolation mechanism forms an integrated structure that is detachably connected to each other, thereby improving the overall stability of the device and the flexibility of use.

[0014] The beneficial effects of the present invention are as follows: since the present invention adopts several groups of isolation mechanisms located in the middle of the road, the lifting guardrail of the isolation mechanism is located in the guardrail accommodating groove below the road surface, and guardrail lifting pillars are respectively arranged below the two ends of the lifting guardrail; the guardrail lifting pillars include guardrail lifting column piles fixedly arranged below the road surface, and the guardrail lifting column piles are provided with guardrail lifting columns inside, and guardrail lifting telescopic rods are arranged between the guardrail lifting columns and the guardrail lifting column piles, and the lower end of the guardrail lifting telescopic rod is connected to the driving end of the guardrail lifting drive device; the two ends of the lifting guardrail are respectively connected to the upper end of the guardrail lifting column through column connectors, so its design is reasonable and the structure is compact. According to the different traffic flow conditions of the forward lane and the reverse lane, and combined with the needs of traffic management, the corresponding isolation mechanism is raised or lowered, thereby changing the driving direction of several lanes in the middle of the road. Thus, it can alleviate the traffic pressure on the highway to a certain extent, divert traffic, improve the utilization rate of the road, and can be used as an effective means to alleviate traffic congestion. At the same time, the new central divider system for smart highways can quickly and efficiently set or remove the central divider through the automatically rising and falling isolation mechanism, saving the cost of road maintenance. In addition, it can also ensure driving safety, avoid traffic accidents caused by other vehicles cutting in, and effectively ensure the smoothness and safety of vehicles during driving.

DETAILED DESCRIPTION

[0025] according to Figures 1 to 11 The specific structure of the present invention is described in detail. The new central median system for smart highways includes several groups of isolation mechanisms located in the middle of the road, wherein each group of isolation mechanisms is composed of two rows of guardrail assemblies arranged in parallel, and each row of guardrail assemblies includes several continuously arranged lifting guardrails 1. The lifting guardrail 1 of the isolation mechanism is located in the guardrail accommodating groove 6 below the road surface 5, and guardrail lifting pillars 2 are respectively arranged below the two ends of the lifting guardrail 1. The guardrail lifting pillar 2 includes a guardrail lifting column pile 8 fixedly arranged below the road surface 5, and a guardrail lifting column body 9 is arranged inside the guardrail lifting column pile 8; between the guardrail lifting column body 9 and the guardrail lifting column pile 8, a guardrail lifting telescopic rod 10 for driving the guardrail lifting column body 9 to rise and fall is arranged, and the lower end of the guardrail lifting telescopic rod 10 is connected to the driving end of the guardrail lifting drive device 11, and the control end of the guardrail lifting drive device 11 is also electrically connected to the guardrail lifting control module.

[0026] The two ends of each lifting guardrail 1 of the isolation mechanism guardrail assembly are connected to the upper end of the guardrail lifting column 9 of the corresponding side guardrail lifting pillar 2 through the column connector 14. The upper end of the guardrail lifting column 9 of the guardrail lifting pillar 2 is also provided with a red and green working status indicator light 12; and then the various working states of the system are distinguished by the indicator lights of different colors. For example: if the working status indicator light 12 is red, it means that the isolation mechanism in the middle of the road surface 5 is in the closed state; if the working status indicator light 12 is green, it means that the isolation mechanism in the middle of the road surface 5 is in the open state, and the moving vehicle should slow down and change lanes immediately.

[0027] Two horizontally arranged guardrail protection covers 7 are movably arranged above the lifting guardrail 1 inside the guardrail accommodating groove 6 below the road surface 5. The ends of the two guardrail protection covers 7 are respectively located in the cover grooves 13 arranged on both sides of the upper opening of the guardrail accommodating groove 6, and a sealing rubber sleeve is also arranged between the cover groove 13 and the guardrail protection cover 7; at the same time, the cover grooves 13 on both sides are respectively provided with cover driving mechanisms for opening and closing the guardrail protection cover 7. The closed guardrail protection cover 7 is used to protect and shield the lifting guardrail 1 of the isolation mechanism in the lowered state, thereby facilitating the normal driving of vehicles when the number of forward lanes 24 and reverse lanes 25 on the road surface 5 changes.

[0028] Between the two rows of guardrail assemblies of each isolation mechanism, which are composed of a plurality of continuously arranged lifting guardrails 1, a plurality of groups of anti-glare partitions 3 arranged along the direction of vehicle travel are also arranged; the anti-glare partitions 3 are located below the road surface 5, and anti-glare panel lifting pillars 4 are respectively arranged below each group of anti-glare partitions 3; the anti-glare partitions 3 are driven by the anti-glare panel lifting pillars 4 to rise and fall accordingly with the rise and fall of the lifting guardrail 1. Thus, the anti-glare partitions 3 arranged between the two rows of guardrail assemblies are used to effectively block the lights of vehicles on the opposite lane, thereby improving the driving safety of vehicles passing by.

[0029] The anti-glare board lifting support column 4 includes an anti-glare board lifting column pile 15 fixedly arranged below the road surface 5, an anti-glare board lifting column body 16 is arranged inside the anti-glare board lifting column pile 15, and an anti-glare partition 3 is arranged inside the anti-glare board lifting column body 16. An anti-glare board lifting telescopic rod 17 is arranged between the anti-glare partition 3, the anti-glare board lifting column body 16 and the anti-glare board lifting column pile 15, and the anti-glare board lifting telescopic rod 17 is composed of a telescopic primary rod 20 and a telescopic secondary rod 21. The anti-glare partition 3 is connected to the telescopic secondary rod 21 of the anti-glare board lifting telescopic rod 17 through an anti-glare board connecting fixture 22, so as to flexibly replace the anti-glare partition 3 with different structures according to the needs of the specific use environment. The lower end of the anti-glare panel lifting telescopic rod 17 is connected to the driving end of the anti-glare panel lifting drive device 18, and the control end of the anti-glare panel lifting drive device 18 is electrically connected to the anti-glare panel lifting control module; and then the anti-glare panel lifting telescopic rod 17 is used to drive the anti-glare panel lifting column 16 in the anti-glare panel lifting column pile 15 and the anti-glare partition 3 in the anti-glare panel lifting column 16 to rise or fall in sequence and continuously, so as to increase the telescopic height of the anti-glare partition 3 and improve the flexibility of the device. In addition, in order to play the role of indication and lighting, the upper outer side of the anti-glare panel lifting column 16 of each anti-glare panel lifting pillar 4 is also provided with a guide lighting lamp 19.

[0030] The guardrail lifting pillars 2 at the ends of two adjacent groups of lifting guardrails 1 of the isolation mechanism guardrail assembly are detachably connected through the guardrail pillar connector 23, so that the groups of lifting guardrails 1 of the isolation mechanism form an integrated structure that is detachably connected to each other, which improves the overall stability of the device and the flexibility of use. The guardrail lifting control module, the anti-glare plate lifting control module, the cover plate driving mechanism, the working status prompt light 12 and the guide lighting 19 are respectively electrically connected to the overall control system set at the highway toll station (for example, they can be connected via wireless signals). In addition, a solar cell power supply system is also set on one side of the road to ensure that the entire system can still work normally in the event of a sudden power outage.

[0031] When the new central dividing strip system for smart highways is used, when the number of vehicles on the forward lane 24 and the reverse lane 25 is equal or not congested, the two rows of guardrail assemblies (several continuously arranged lifting guardrails 1) and the anti-glare partition 3 of a group of isolation mechanisms located in the middle of the road are lifted, thereby facilitating the normal driving of vehicles. If the highway monitoring system detects that there are many vehicles or congestion in the forward lane 24 (or the reverse lane 25), the overall control system controls the guardrail lifting control module and the anti-glare panel lifting control module of a group of isolation mechanisms in the middle position, and drives the guardrail lifting telescopic rod 10 and the anti-glare panel lifting telescopic rod 17 to drive the lifting guardrail 1 and the anti-glare partition 3 to descend below the road surface 5, and then, through the cover driving mechanism, the guardrail protection cover 7 located in the cover groove 13 on both sides of the upper end opening of the guardrail accommodating groove 6 is closed to protect and shield the lifting guardrail 1 of the isolation mechanism in the lowered state. At the same time, the guardrail protection cover 7 of a group of isolation mechanisms located in the middle of the road, close to the reverse lane 25 (or the forward lane 24) is opened, and then the guardrail lifting and telescopic rod 10 of the isolation mechanism drives the guardrail lifting column 9 and the lifting guardrail 1 to rise, and the anti-glare plate lifting and telescopic rod 17 drives the anti-glare plate lifting column 16 and the anti-glare partition 3 to rise, so that according to the actual vehicle flow, the raised isolation mechanism 27 is used to flexibly change the number of forward lanes 24 and reverse lanes 25 to ensure that vehicles on the road can travel normally.
