Description

Technical Field

[0001] The invention relates to the field of traffic engineering, and in particular to a lane changer capable of realizing the conversion between a lane dividing line and a virtual line. Background Art

[0002] Lane dividing lines are used to separate traffic flows going in the same direction. They are usually white dashed or solid lines or yellow dashed or solid lines. White dashed lines separate vehicles going in the same direction. You can change lanes or overtake under safe conditions. White solid lines also separate vehicles going in the same direction, but you cannot change lanes. Yellow solid lines separate vehicles going in different directions. Sometimes they separate vehicles going in the same direction. They can be used as dividing lines or center lines. You cannot change lanes. Yellow dashed lines can be used as dividing lines or center lines. You can change lanes when they are used as dividing lines.

[0003] The existing lane dividing lines are fixed dashed lines or solid lines or a combination of the two. If congestion occurs, the main ways to adjust the lanes are as follows:

[0004] Method 1: Artificially place obstacles such as roadblocks and change the route in combination with on-site signs; or traffic police and other personnel direct on-site. The disadvantage is that on-site arrangement is time-consuming and labor-intensive, and the timeliness is poor.

[0005] Method 2: Set up "tidal lanes" and implement lane changes at specific times in combination with traffic signals. The disadvantage is that the location and time period are relatively limited and can only be used at specific times in specific locations. It cannot be used for congestion caused by emergencies.

[0006] Method 3: By setting up a mechanical system that can push the obstacles that serve as lane demarcations on specific road sections, lane changes are implemented in combination with traffic signals. The disadvantage is that it is very limited in location and time period, and is used in specific time periods at specific locations, and the investment cost is high. It cannot be used on a large scale and cannot be used for congestion caused by emergencies.

[0007] The above methods are not able to adjust the number of two-way traffic lanes by directly changing the fixed lane dividing lines to achieve the purpose of quickly improving traffic congestion, which is very inconvenient. Summary of the invention

[0029] In this embodiment, the shell 1 is a protective shell with a rectangular three-dimensional structure (but not limited to this), which is configured as a modular packaging structure. During construction, a groove is opened at the required burial position, and the shell is buried and fixed. The burial depth is about 50 cm.

[0030] The bottom of the shell 1 is fixed to the bottom of the dividing line groove, and the top surface of the shell 1 is flush with the road surface. The top surface of the shell 1 is made of transparent material, and its top surface is finely frosted. The top of the protective shell is designed to be transparent, and the surface is finely frosted. With the help of diffuse reflection, there is no "reflection" and the color of the entire lower cover panel and the moving table panel can be exposed. At the same time, it softens the slight color difference between the two due to the layers. This embodiment also includes a number of load-bearing columns (such as Figure 1 or Figure 2 The first to fourth load-bearing columns 14 to 17 are provided in the embodiment, wherein one end of each of the load-bearing columns is connected to the top of the shell 1 , and the other end is connected to the bottom of the shell 1 .

[0031] The guide rail slide 4 is fixedly connected to the load-bearing column. The bottom of the protective shell is connected and fixed to the installation groove dug out of the road surface, and the top is connected and fixed to the adjacent road surface; the entire protective shell plays a protective role in bearing pressure, shockproof, anti-extrusion of external forces, waterproof, moisture-proof, and anti-chemical corrosion. The protective shell also acts as a mounting bracket for the components installed inside.

[0032] During construction, dig a groove of equal width and slightly deeper depth at the position where the boundary line needs to be divided on the road surface, and lay a steel plate at the bottom of the groove line, so that the height of the rear transformer is flush with the road surface on both sides after the protective shell, internal components and the entire transformer module are placed, and the transformer is fixed to the base steel plate. The gaps on both sides connected to the road surface are filled with road filling materials, and when constructing the boundary area 30-31 area on the edge of the cover panel 2, pour road asphalt (or cement) on top to connect it with it.

[0033] The cover panel 2 is connected and fixed to the top of the protective shell through a fixing hole 40. The panel is intermittently composed of a first filling color block (white or yellow), a paint color block) and a hollow color block. The hollow color block displays the color corresponding to the movable table panel directly below. When the movable table panel below moves to a different color block, the color of the hollow color block changes accordingly. The cover panel 2 does not bear pressure, and the pressure of road vehicles will be borne by the protective shell. The movable table panel 3 is arranged below the cover panel 2, and there is a gap between the movable table panel and the cover, and the gap ranges from 0.1 to 5 cm. The movable table panel 3 is intermittently composed of a second filling color block (white or yellow), a paint color block and a road surface color block (usually asphalt or cement color).

[0034] Also includes: a plurality of connecting columns (such as 1 and Figure 2 The first connecting column 18 to the third connecting column 20) and a plurality of rollers (such as 1 and Figure 2 The first roller 21 to the third roller 23), one end of each of the connecting columns is connected to the movable table panel 3, and the other end is correspondingly connected to the roller, and the roller is arranged in the track groove 13 provided on the guide rail slide 4, and reciprocates along the track groove 13.

[0035] A guide rail slide 4 is arranged under the movable table panel 3, and the guide rail slide 4 is respectively connected and fixed to the protective shell and the load-bearing column. The connecting column of the movable table panel 3 is connected to the small roller, and the small roller is connected to the track groove 13 of the track slide. The movable table panel 3 moves along the guide rail slide 4, and the operation is stable and the friction resistance is small.

[0036] The guide rail slide 4 is fixed on the load-bearing column by using the first to fourth fixing screws 26 to 29 respectively.

[0037] The driving device includes: a bracket 8, a driving motor 6, a rack 5, a first limit spring rod 11, a second limit spring rod 12, a first limit touch point 10 and a second limit touch point 9; the bracket 8 is arranged at one end of the shell 1, the driving motor 6 is arranged on the bracket 8, one side of the rack 5 is connected to one end of the movable table panel 3, and the other side is connected to the driving motor 6; the first limit spring rod 11 is arranged on the bracket 8, the second limit spring rod 12 is arranged on the load-bearing column, the first limit spring rod 11 and the second limit spring rod 12 are located on both sides of the rack 5, the first limit touch point 10 and the second limit touch point 9 are both arranged on the rack 5, and the driving motor 6 drives the rack 5 to transmit, so that Push the movable table panel 3 forward or backward, when the rack 5 moves to the first set position, the first limit touch point 10 correspondingly touches the first limit spring rod 11 (the second limit touch point 9 does not touch the second limit spring rod 12), and the drive motor 6 disconnects the circuit so that the movable table panel 3 stops moving when it reaches the first set position; the drive motor 6 drives the rack 5 to transmit to push the movable table panel 3 forward or backward, when the rack 5 moves to the second set position, the second limit touch point 9 correspondingly touches the second limit spring rod 12 (the first limit touch point 10 does not touch the first limit spring rod 11), and the drive motor 6 disconnects the circuit so that the movable table panel 3 stops moving when it reaches the second set position.

[0038] When the movable table panel 3 is at the first set position, the second filled color blocks on the movable table panel 3 are directly opposite to the hollow color blocks on the cover panel 2. At this time, all the second filled color blocks are combined with the first filled color blocks to form a solid line of the road surface dividing line; when the movable table panel 3 is at the second set position, the road surface color blocks on the movable table panel 3 are directly opposite to the hollow color blocks on the cover panel. At this time, all the road surface color blocks are combined with the first filled color blocks to form a dotted line of the road surface dividing line.

[0039] It is ensured that the movable table panel 3 does not move after moving to the designated position. The driving motor 6 is provided with a control interface which is electrically connected to the controller, and the direction of the motor rotation can be controlled.

[0040] When the movable table panel 3 moves, its different color blocks are respectively combined with the white (or yellow) paint blocks of the cover panel 2 through the hollow color blocks of the cover panel 2. When the two are consistent, a visual solid line is formed, and when the two are inconsistent, a visual dotted line is formed. By changing the combination, a change in the visual solid line or dotted line is formed. The principle is to use different layers to form different combinations by moving the upper and lower color blocks. When the two are consistent, a visual solid line is formed, and when the two are inconsistent, a visual dotted line is formed. By changing the combination, a change in the visual solid line or dotted line is formed, thereby completing the line conversion.

[0041] The driving motor 6 has a multi-speed power adjustment function. The driving motor 6 is provided with a control port, which can be connected to the network to realize remote control of the driving motor 6. The driving motor 6 itself has a waterproof function.

[0042] The above-mentioned transformer is configured as a main module (specific structure as shown in Figure 1 As shown) and extension modules (specific structure as shown Figure 2 As shown), the difference between the two is that the extension module does not have an independent power device, and both the main module and the extension module are provided with an extension connection point 24, and the extension connection point 24 is located 0.5-2cm away from the edge, which can be spliced. During use, the total length of the line changer can be adjusted by assembling the main module and several extension modules according to the actual length of the paved section. Reserved openings 25 can be set at the ends of the shell 1 to enable the assembly of the main module and several extension modules. The line changer can be used as a single dividing line composed of several modules, or it can be used in combination of multiple dividing lines. When used in combination, the function of borrowing the lane on the opposite side can be realized.

[0043] Please continue to refer to Figure 4 As shown, one end of the mobile platform panel in the extension module is provided with an extension connection point A end, and the other end thereof is provided with an extension connection point B end 46 for connecting with the adjacent main module and

[0044] / or the movable table panels between the extension modules are spliced ​​to play a connecting role.

[0045] The movable table panel 3 is connected to the connecting column by means of a plurality of screws passing through the mounting holes 47 .

[0046] This embodiment further includes: a water guide groove 7, which is arranged inside the bottom of the housing 1 and is used to guide water flow to the outside of the housing 1. If water penetrates into the housing 1, the water entering the housing 1 can be guided to the outside of the housing 1.

[0047] It is understandable that the above embodiment can alleviate the congestion caused by road construction and the congestion caused by sudden traffic accidents by adjusting the changes in the interface of the two-way lanes. The situation where the virtual and real lines need to be changed from time to time according to the situation can be achieved by adjusting the changes between the same-direction lanes (dividing lines).

[0048] For example, in some situations, it is necessary to allow lane changes between several lanes on the same side to make full use of road resources; sometimes it is necessary to prohibit vehicles from cutting in to alleviate congestion caused by cutting in and reduce the accident rate. The traditional dividing line is fixed and cannot meet the repeated switching between virtual and real lines.

[0049] The lane changer provided in this embodiment can quickly realize the mutual conversion between the dotted and solid lines of the lane dividing line according to the ever-changing road conditions by setting a lane changer that realizes the conversion between the virtual and solid lines of the lane dividing line. Combined with auxiliary systems such as road signal lights, by changing the number of lanes on both sides, the utilization rate of road resources is improved, and traffic congestion is effectively alleviated. And there is no need to re-draw the lines, and the dividing line can be repeatedly switched between the dotted line and the solid line, and it has repeatability and rapid response. It is easy to produce and low cost, easy to manufacture, simple to construct, low energy consumption, not affected by time period, and suitable for a variety of road scenarios.
