Description

Technical Field

[0001] The present invention relates to the technical field of variable lane guardrails, and specifically to a modular variable lane guardrail based on tidal lanes. Background Art

[0002] With the continuous advancement of the urbanization process and the continuous increase in the vehicle ownership, the problem of traffic congestion has become increasingly prominent. To solve this problem, a new type of traffic management method - tidal lanes has emerged. A tidal lane is a special lane whose traffic flow regulations are dynamically adjusted according to the traffic flow changes in different time periods to make the best use of the lane resources and relieve traffic congestion.

[0003] However, the implementation of tidal lanes requires a series of traffic facilities, and an important facility among them is the variable lane guardrail. The current variable lane guardrails are often of an integral structure rather than a modular structure. The so-called modular means that each module can work independently, and even if a single group of modules fails, it does not affect the operation of the entire system. In the current variable lane guardrails, when a certain variable lane guardrail fails, it is often very difficult to complete the action of the overall lane change.

[0004] Therefore, it is necessary to provide a modular variable lane guardrail based on tidal lanes to solve the problems raised in the above background art. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solution: A modular variable lane guardrail based on tidal lanes, comprising:

[0006] At least two columns, and two hinge seats arranged symmetrically up and down are fixed on both sides of each column;

[0007] Hinge rods, which are hinged to the hinge seats, and guardrail rods are connected between two hinge rods on the same horizontal plane between adjacent columns, and a guardrail body is connected between two guardrail rods between adjacent columns;

[0008] A moving seat, which is fixed on the column and has a moving power; and

[0009] A guiding belt, which is laid on the lane and used to provide guidance for the moving seat;

[0010] When the variable lane guardrail changes lanes, multiple moving seats move simultaneously at the same speed.

[0011] Further, preferably, the hinge rod includes a rod body, which has a vertical through hole, and a ring-shaped connecting piece is attached to the vertical through hole. The connecting piece has the ability of elastic deformation, and the connecting piece is hinged to the hinge seat by a hinge column.

[0012] Further, preferably, a positioning groove is formed on one side of the rod body facing the column, a sliding groove corresponding to the positioning groove is formed in the column, a sliding seat is slidably arranged in the sliding groove, a positioning column is fixed at one end of the sliding seat, and the positioning column can slide through the hinge seat and extend into the positioning groove.

[0013] Further, preferably, a return spring is also connected to the sliding seat in the sliding groove, and the return spring is configured to have a tendency to drive the sliding seat to move towards the positioning groove;

[0014] An electromagnetic block is also arranged in the sliding groove, and the electromagnetic block is configured to adsorb the sliding seat and make the sliding seat away from the positioning groove when electrified;

[0015] The moving seat includes an integrated bin, a power supply module and a control module are arranged in the integrated bin. Before the moving seat is started, the control module detects the power of the power supply module, and when the power is less than 10%, the power supply to the moving seat and the electromagnetic block is stopped.

[0016] Further, preferably, the guiding belt is fixed on the road surface by bolts or semi-embedded in the roadbed. The guiding belt has two symmetrically arranged inclined surfaces, a plane is between the two inclined surfaces, and a guiding groove is formed on the plane;

[0017] The plane is the highest surface of the guiding belt, and its height from the road surface is 3-5 cm;

[0018] The moving seat includes an integrated bin, and driving wheels are arranged in a driving bin below the integrated bin, and the driving wheels can move in the guiding groove.

[0021] Further, preferably, a base shaft is fixed between two adjacent limiting plates, a guiding rod is rotatably arranged on the base shaft, a limiting protrusion is arranged on the guiding rod, and a limiting seat corresponding to the limiting protrusion is arranged on the driving wheel.

[0022] Further, preferably, both ends of the limiting protrusion are shorter than both ends of the guiding rod, an electromagnetic strip is fixed on the outer surface of the base shaft, and a magnet strip is fixed on the inner wall of the guiding rod.

When the variable lane guardrail changes lanes, multiple said moving seats move simultaneously at the same speed, improving the lane-changing speed of the variable lane guardrail in the tidal lane. Additionally, even if a single moving seat fails, it does not affect the operation of the entire system, ensuring the stable operation of the tidal lane. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Please refer to Figures 1-7 , in the embodiment of the present invention, a modular variable lane guardrail based on a tidal lane is provided, including:

[0034] At least two columns 1, and two hinge seats 2 arranged symmetrically up and down are fixed on both sides of the column 1;

[0035] Hinge rods 3, which are hinged to the hinge seats 2, and guardrail rods 4 are connected between two hinge rods 3 on the same horizontal plane between adjacent columns 1, and a guardrail body 5 is connected between two guardrail rods 4 between adjacent columns 1;

[0036] A moving seat 6, which is fixed on the column 1 and has a moving power; and

[0037] A guiding belt 12, which is laid on the lane and used to guide the moving seat 6;

[0038] When the variable lane guardrail changes lanes, multiple moving seats 6 move simultaneously at the same speed.

[0039] It should be noted that in this embodiment, the configured guiding belt 12 can guide the movement of the moving seat 6 and prevent the situation of unsmooth movement caused by the deviation of the moving seat 6 itself. And the guiding belt 12 is laid on the lane and hardly damages the road surface structure; specifically, the guiding belt 12 is fixed on the road surface by bolts 15 or semi-embedded in the roadbed;

[0040] In addition, it should be explained that during implementation, the height of the guiding belt 12 is minimized as much as possible, and the distance between adjacent columns 1 is lengthened, so as to reduce the impact on the vehicle body. And because the traffic flow of the tidal lane is large and the vehicle speed is slow, the impact on the vehicle body can be further reduced.

[0041] During implementation, the moving seat 6 needs to cooperate with the traffic lights, or rather, the traffic lights at adjacent intersections should cooperate with the moving seat 6 to ensure that when the moving seat 6 moves, multiple moving seats 6 move simultaneously at the same speed;

[0042] In this embodiment, the hinge rod 3 includes a rod body 31, which has a vertical through hole, and an annular connecting piece 33 is attached to the vertical through hole. The connecting piece 33 has the ability of elastic deformation, and the connecting piece 33 is hinged to the hinge seat 2 by a hinge column.

[0043] Although multiple moving seats 6 move simultaneously at the same speed, due to various reasons, such as the different frictions between the moving seats 6 and the guiding belt 12, in fact, multiple moving seats 6 cannot maintain exactly the same speed. And the connecting piece 33 can allow this speed difference because it has the ability of elastic deformation.

[0044] In addition, a positioning groove 32 is formed on one side of the rod body 31 facing the column 1, a sliding groove corresponding to the positioning groove 32 is formed in the column 1, a sliding seat 9 is slidably arranged in the sliding groove, a positioning column 8 is fixed at one end of the sliding seat 9, and the positioning column 8 can slide through the hinge seat 2 and extend into the positioning groove 32.

[0045] A return spring 11 is also connected to the sliding seat 9 in the sliding groove, and the return spring 11 is configured to have a tendency to drive the sliding seat 9 to move towards the positioning groove 32;

[0046] An electromagnet 10 is also arranged in the sliding groove, and the electromagnet 10 is configured to adsorb the sliding seat 9 and move the sliding seat 9 away from the positioning groove 32 when electrified;

[0047] The moving seat 6 includes an integrated bin 61, a power supply module and a control module are arranged in the integrated bin 61. Before the moving seat 6 is started, the control module detects the power of the power supply module, and when the power is less than 10%, the power supply to the moving seat 6 and the electromagnet 10 is stopped.

[0048] It should be noted that after the moving seat moves, the power supply to the moving seat 6 and the electromagnet 10 is cut off, and the electromagnet 10 is configured to adsorb the sliding seat 9 and move the sliding seat 9 away from the positioning groove 32 when electrified; therefore, when the electromagnet is powered off, the return spring 11 drives the sliding seat 9 to move towards the positioning groove 32, so that the positioning column 8 slides through the hinge seat 2 and extends into the positioning groove 32 for positioning, making multiple moving seats form a rigid whole, which is convenient for improving the overall stability;

[0049] Moreover, when the power supply module in a certain moving seat 6, due to some reasons such as aging or damage, results in a situation where the power supply modules in other moving seats are fully charged while the power supply module in this moving seat 6 has a power less than 10% during a certain period, the power supply to this moving seat 6 and the electromagnet 10 is stopped. At this time, when the electromagnet is powered off, a rigid whole is formed between the hinge rod adjacent to this moving seat 6 and this moving seat 6. Then, with the assistance of other moving seats, this powered-off moving seat can move accordingly. Therefore, even if a single set of moving seats 6 fails, it does not affect the operation of the entire system, ensuring the stable operation of the tidal lane, and this rigid whole is convenient for this moving seat to accurately reach the designated position subsequently;

[0050] In this embodiment, the guiding belt 12 has two symmetrically arranged inclined surfaces 13, a flat surface 14 is between the two inclined surfaces 13, and a guiding groove 16 is formed on the flat surface 14;

[0051] The flat surface 14 is the highest surface of the guiding belt 12, and its height from the road surface is 3 - 5 cm;

[0052] The moving seat 6 includes an integrated bin 61. Below the integrated bin 61, a driving bin 63 is provided with driving wheels 64, and the driving wheels 64 can move in the guiding groove 16.

[0053] Below the integrated bin 61, a weight increasing block 62 corresponding to the inclined surface 13 and the flat surface 14 is further provided.

[0054] Among them, the cooperation between the inclined surface 13 and the weight increasing block 62 can realize the guiding of the integrated bin, and the weight increasing block can also improve the stability of the column.

[0055] In this embodiment, limiting plates 18 are fixed on both sides of the guiding groove 16, and pressure sensors are embedded in the limiting plates 18.

[0056] In this embodiment, a base shaft 20 is fixed between two adjacent limiting plates 18. A guiding rod 17 is rotatably arranged on the base shaft 20. A limiting protrusion 19 is arranged on the guiding rod 17, and a limiting seat 65 corresponding to the limiting protrusion 19 is arranged on the driving wheel 64.

[0057] In addition, both ends of the limiting protrusion 19 are shorter than both ends of the guiding rod 17. An electromagnetic strip 21 is fixed on the outer surface of the base shaft 20, and a magnet strip 22 is fixed on the inner wall of the guiding rod 17. When the electromagnetic strip 21 is electrified, it can push the magnet strip 22 away from the electromagnetic strip 21, so that the limiting protrusion 19 deflects and corresponds to the limiting seat 65. When the moving seat moves to the end of the guiding groove 16, the limiting seat 65 is separated from the limiting protrusion 19, and the moving seat will generate a pressure on the limiting plate 18, which is then detected by the pressure sensor. At this time, the control module controls the power supply module to cut off the power supply to the electromagnetic strip. After the magnet strip loses the thrust, the limiting protrusion deflects under the action of gravity to realize the jamming of the limiting seat 65 and prevent it from moving randomly.

[0058] When the moving seat is about to start, the control module detects the power of the power supply module. When the power is less than 10%, the power supply to the moving seat 6 and the electromagnetic block 10 is stopped, but the remaining power is used to supply power to the electromagnetic strip, so that the limiting protrusion 19 can be reset to release the jamming of the limiting seat and prevent the moving seat from being unable to move due to the restriction.

[0059] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
