Description

Technical Field

[0001] This utility model belongs to the field of road traffic, and specifically relates to a lane control device for changing the position of guardrails. Background Technology

[0002] On highway toll plazas and urban roads, during peak hours, some sections exhibit significant differences in the number of vehicles traveling in two directions. This can lead to congestion in one direction while lanes in the other are partially unused. Conversely, during another peak period, the congestion situation on the same section can reverse. This situation easily causes traffic chaos and increases the difficulty of managing traffic during peak hours.

[0003] To address traffic congestion, transportation authorities employ methods such as odd-even license plate restrictions and increasing traffic police presence to maintain order. One solution for managing peak-hour traffic is the use of tidal flow lanes. These lanes are manually controlled or adjusted using lane lights to increase the number of lanes in the direction with higher traffic volume during peak hours, reducing the number of unused lanes. However, because tidal flow lanes are only distinguished from other lanes by lane markings without a median strip, drivers can easily mistakenly enter tidal flow lanes, creating a dangerous situation of vehicles traveling in the wrong direction.

[0004] Therefore, in road sections where it is not possible to increase the road width, it is considered to change the number of lanes in both directions by setting up variable-position guardrails, while keeping the total number of lanes unchanged. This would alleviate congestion during the morning and evening peak hours and prevent drivers from accidentally entering tidal flow lanes. Summary of the Invention

[0005] The purpose of this utility model is to provide a lane control device for changing the position of guardrails. The lane control device is used to replace the existing fixed guardrails. The lane control device is pre-buried underground and can change the number of lanes in both directions as needed, and change the number of lanes in a single direction during morning and evening peak hours and off-peak hours.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A lane control device for switching the position of a guardrail, the lane control device includes a housing and a moving unit and a belt drive unit located inside the housing; and the lane control device includes two first positions and an intermediate position, which respectively correspond to two lane lines away from the intermediate position and the intermediate position of two adjacent lanes with opposite running directions.

[0008] The moving unit includes a guide rail, a platform, a guardrail magnet, and a platform magnet; the guide rail is arranged along the length of the box and is fixed inside the box; the platform is slidably connected to the guide rail and can reciprocate along the length of the box, and the platform magnet is fixedly arranged in the middle of the platform;

[0009] The guardrail magnet is located on the upper surface of the box and can move with the platform magnet under the action of magnetic force; a guardrail seat is fixed on the guardrail magnet and the guardrail seat is used for threaded connection with the guardrail.

[0010] The belt drive unit includes a motor, a belt, a first pulley, and a second pulley. The motor is powered by an external power source and can rotate in both directions. The two first pulleys are fixed on the platform and located on both sides of the platform magnet. The two second pulleys are located inside the housing near both ends along the length of the housing. The belt is sleeved on the outside of the first and second pulleys and is used to drive the belt and the first and second pulleys connected to it to rotate when the motor rotates in the forward / reverse direction, thereby causing the platform to move along the guide rail.

[0011] A column is set at each end of the guide rail to limit the platform, and when one end of the platform abuts against either column, the position of the platform magnet on it corresponds to the first position of the lane control device; the center of the guide rail is the middle position of the lane control device.

[0012] Furthermore, the guardrail is arranged perpendicular to the length direction of the box body, and the guardrail can move along the length direction of the box body.

[0013] Furthermore, when the platform magnet is in the first position, the guardrail seat magnet and guardrail seat, which are magnetically connected to it, drive the guardrail located on top of the guardrail seat to also be in the first position, thereby moving the guardrail to a lane line away from the middle position between the two adjacent lanes; when the platform magnet is in the middle position, the guardrail seat magnet and guardrail seat, which are magnetically connected to it, drive the guardrail located on top of the guardrail seat to also be in the middle position, thereby placing the guardrail in the middle lane line between the two adjacent lanes.

[0014] Furthermore, the length of the housing of the lane control device is at least equal to the width of two adjacent lanes, and the housing is arranged along the width direction of the lane; and the housing is buried underground, while the guardrail base is at least partially exposed above the ground.

[0015] Furthermore, one or more support structures may be installed between the upper cover and the base to ensure support for ground vehicles.

[0016] Furthermore, the motor is equipped with a motor gear, and a pulley gear is provided below the second pulley near the motor, with the motor gear meshing with the pulley gear; a shaft is provided at each end of the rear side of the column near the length of the housing, with the second pulley fitted on it; the two ends of the belt are respectively fixed to a column and pass through the first and second pulleys. Preferably, the motor is a geared motor.

[0017] Preferably, the platform moves at a speed of 0.01-0.05 m / s, which ensures that the platform magnet can drive the guardrail magnet to maintain mutual attraction, thereby enabling the guardrail to move to the designated position.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this utility model are:

[0019] The belt drive unit of the lane control device described in this utility model can drive the platform to reciprocate along the guide rail. The guardrail seat magnet moves with the platform under the attraction of the platform magnet fixed on the platform, thereby driving the guardrail fixed on the guardrail seat to move along the length of the box, thereby switching the position of the isolation guardrail of two adjacent lanes.

[0020] The lane control device described in this utility model is used to replace the existing fixed guardrails. The lane control device is pre-buried underground and can change the number of lanes in both directions mechanically as needed, without manual operation. During morning and evening peak hours and off-peak hours, the number of lanes in a single direction can be changed. Attached Figure Description

[0037] To make the objectives, technical solutions, beneficial effects, and significant advancements of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings provided in the examples of this utility model. Obviously, all the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] like Figure 1As shown, a lane control device 21 for switching the position of a guardrail is installed at two adjacent highway toll stations with opposite directions of entry and exit, used to activate tidal lanes during highway congestion periods. The lane control device includes a housing and a moving unit and a belt drive unit located within the housing; the lane control device includes a left first position, a right first position, and a middle position, corresponding to the left lane line 22, right lane line 23, and middle position 24 of two adjacent lanes with opposite directions of operation, respectively, away from the middle position. The lane control device includes a rectangular housing pre-buried underground, including a parallel upper cover 1 and a base 4. Two parallel long sidewalls 2 are provided between the upper cover 1 and the base 4. A left sidewall 3 and a right sidewall 5 are provided parallel at both ends of the long sidewalls 2. The components of the housing are connected to each other by bolts and nuts. After fixing, sealant is applied to the joints to ensure the overall airtightness of the device, preventing water and dirt from entering the housing. The interior of the right side wall 5, long side wall 2, left side wall 3, and base 4 is a hollow truss structure, which reduces the overall weight of the device while ensuring its sturdiness. Furthermore, as... Figure 2 As shown, there is a through hole on the right side wall 5 for the power supply cable to pass through, and sealant is applied after the cable passes through.

[0039] like Figure 1 and Figure 6 As shown, a guardrail magnet 18 is provided on the upper surface of the upper cover 1. The guardrail magnet 18 is movable relative to the upper surface, and a guardrail seat 7 is fixed on the guardrail magnet 18. The guardrail magnet 18 and the guardrail seat 7 are connected by bolts and threads. There is a gap between the guardrail seat 7 and the upper cover 1 to reduce the friction generated when the guardrail seat moves. The guardrail seat 7 protrudes from the ground and has a threaded hole at its top for installing guardrails of different structural forms. When the guardrail is not needed, a platform bolt 6 is installed to ensure that the inside of the threaded hole is kept clean.

[0040] Without affecting the internal movement of the device, a variable number of support structures can be installed between the upper cover 1 and the base 4 to ensure support for ground vehicles.

[0041] like Figure 3-6As shown, a guide rail 11 extending along the length of the base 4 is provided on the base 4. The guide rail 11 is connected to the base 4 by bolt threads, and the two ends of the base 4 are equidistant from the left and right side walls. A slider 17 is slidably connected to the guide rail 11 and can reciprocate along the guide rail 11. A platform 12 is connected to the top surface of the slider 17 by bolt threads. A first pulley 10 is mounted near each end of the platform 12, located on the left and right sides of the platform 12, respectively. A platform magnet 9 is mounted at the center of the platform 12 (between the two pulleys 10). The platform magnet 9 is connected to the platform 12 by bolt threads. Both the platform magnet 9 and the first pulleys 10 can reciprocate along the guide rail 11 with the platform 12. The platform magnet 9 attracts the guardrail magnet 18 on the upper cover 1, and the guardrail magnet 18 can reciprocate with the platform magnet 9.

[0042] Two columns 16 are installed at both ends of the guide rail 11, and the columns are about 300mm away from the left and right side walls. The height of the columns is slightly higher than the platform position to block the platform 12 and prevent the guardrail seat 7 from detaching from the upper cover 1 when the device is running. The positions of the columns correspond to the first position on the left and the first position on the right of the entire lane control device, and the center position of the guide rail corresponds to the middle position of the entire lane control device.

[0043] A second pulley 20 is installed on the rear side of the column 16, near the left and right side walls. The second pulley 20 is mounted on a rotating shaft, and the bottom of the rotating shaft is fixedly mounted on the base 4. A pulley gear 13 is provided on the lower side of the second pulley 20 near the right side wall 5. The base 4 is also equipped with a motor 15, which is electrically connected to an external power source and is a geared motor capable of rotating in both directions. A motor gear 14 is mounted on the motor 15. Both the motor gear 14 and the pulley gear 13 are bevel gears and mesh with each other. The motor 15 rotates the motor gear 14, which in turn rotates the pulley gear 13, and consequently, rotates the second pulley 20. One end of the belt 8 is fixed to the column 16 on the front left side of the guide rail 11, and the other end passes through the first pulley 10 on the left side of the platform 12, the second pulley 20 on the left side of the guide rail 11, the second pulley 20 on the right side of the guide rail 11, and the first pulley 10 on the right side of the platform 12 in sequence, and is finally fixed to the column 16 on the front right side of the guide rail 11.

[0044] In use, the guardrail is installed on the guardrail base 7 using platform bolts 6, and the platform magnet 9 of the platform 12 is located in the middle position of the guide rail, that is, the guardrail base 7 is located in the middle position of the upper cover 1; the left first position, middle position, and right first position of the lane control device correspond to the left, middle, and right positions of two adjacent lanes with opposite entry and exit directions near the highway entrance, respectively (e.g., the left position is the lane line of the outbound lane away from the middle position, the right lane is the lane line of the inbound lane away from the middle position, and the middle position is the lane line in the middle of the two lanes). Switching the guardrail base 7 between these three positions can adjust the number of lanes in a certain direction. At this time, the guardrail 25 is located in the middle position 24, that is, it is not necessary to increase or decrease the number of lanes in a certain direction.

[0045] During peak hours when entering the city, the motor 15 rotates clockwise (the platform movement speed is set to 0.01 m / s), driving the motor gear 14 to rotate clockwise, which in turn drives the pulley gear 13 to rotate clockwise, and then drives the second pulley 20 located on the right rear side of the device to rotate clockwise. This, via the belt 8, causes the platform 12 to move to the left along the guide rail 11. At this time, the platform magnet 9 on the platform 12 attracts the guardrail seat magnet 18 located on the upper side of the upper cover 1 to move to the left along the top surface of the upper cover, thereby driving the guardrail seat 7 fixedly connected to it to move to the left as well. When the platform 12 is blocked by the left column 16, it stops. At this time, the guardrail 25 on the guardrail seat 7 is located on the left side of the two lanes (left lane 22), meaning that the two adjacent lanes where the device is located are converted into lanes heading into the city in the same direction. Figure 7 As shown.

[0046] After the peak hours for entering the city end, the motor 15 rotates in the opposite direction, and the entire device moves in the opposite direction, causing the guardrail seat 7 to move to the right and stop when it reaches the middle position of the guide rail 11; at this time, the guardrail is located in the middle position 24 between two adjacent lanes, and the left lane is still the lane for entering the city and the right lane is the lane for leaving the city.

[0047] When encountering peak outbound traffic, the motor 15 continues to rotate in the opposite direction, causing the guardrail seat 7 to continue moving to the right until it stops at the right-side post 16. At this time, the guardrail 25 on the guardrail seat 7 is located on the right side of the two lanes (right lane 23), meaning that the two adjacent lanes where the device is located are converted into outbound lanes in the same direction.

[0048] Because the motor speed is set, the platform 12 moves slowly, which in turn causes the guardrail seat 7 to move slowly. This ensures that the platform magnet 9 can drive the guardrail seat magnet 18 to maintain mutual attraction, thereby enabling the guardrail seat 7 to move to the designated position.

[0049] The device described in this utility model can control the guardrail on the guardrail seat 7 to be located on the left, middle and right sides of the upper cover 1 according to the forward and reverse rotation of the motor, so as to correspond to the left, middle and right sides of two adjacent lanes respectively. The switching of the guardrail seat 7 in these three positions can be adjusted according to the number of lanes in a certain direction.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
