Description

Technical Field

[0001] This utility model relates to the field of road traffic technology, and more specifically, to a liftable guardrail device and a tidal lane divider device. Background Technology

[0002] Reversible lanes originated from the need for dynamic adjustment of traffic flow, especially during peak hours when some roads often experience severe traffic congestion due to excessive vehicle density. To address this issue, reversible lanes were developed and initially applied to peak-hour traffic management in some cities.

[0003] During peak hours, due to uneven traffic flow, some lanes experience excessive traffic while others remain relatively empty. Tidal flow lanes dynamically adjust the direction or number of lanes in use, concentrating more lane resources in the direction of higher traffic volume, preventing some lanes from being idle, thereby improving road capacity and alleviating traffic bottlenecks.

[0004] However, many of the tidal flow lanes used in the past did not have guardrails, causing traffic chaos and exacerbating urban traffic congestion. With the advancement of technology, some tidal flow lanes have been separated by separation devices, such as zipper trucks and movable guardrails. However, these separation methods are not very flexible and require a lot of manpower. Therefore, it is necessary to design a flexible, convenient and easy-to-use tidal flow lane separation device. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, with the advancement of technology, some tidal flow lanes are separated by separation devices, such as zipper trucks and movable guardrails. However, these separation methods are not very flexible and require a lot of manpower. Therefore, it is necessary to design a flexible, convenient and easy-to-use tidal flow lane separation device. In view of the above-mentioned defects of the existing technology, a liftable guardrail device is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] Constructing a liftable railing device includes:

[0008] The railing component can be used as a road barrier;

[0009] A lifting assembly, comprising a main body and a lifting part, wherein the lifting part is connected to the railing member and is used to drive the railing member to lift or lower;

[0010] The mounting housing is disposed below the ground, and the lifting assembly is disposed within the mounting housing;

[0011] A power assembly, which is connected to the lifting assembly and is used to provide power to the lifting assembly so that the lifting part can move up and down;

[0012] When the guardrail is needed as a road barrier, the power unit provides power to the lifting assembly, and the lifting part of the lifting assembly drives the guardrail to extend out of the mounting housing. When the guardrail is not needed as a road barrier, the power unit provides power to the lifting assembly, and the lifting part of the lifting assembly drives the guardrail to retract into the mounting housing.

[0013] Optionally, a first warning element is provided on the top of the railing component. The first warning element is used to warn pedestrians and / or people inside the vehicle so that pedestrians and / or people inside the vehicle can notice the railing component in a timely manner.

[0014] Optionally, the first warning element includes a first light source assembly disposed on the top of the railing and a lampshade fitted over the first light source assembly, the lampshade being made of a red transparent material.

[0015] Optionally, a second warning element is provided on the outside or inside of the railing component. The second warning element is used to warn pedestrians and / or occupants of the vehicle so that pedestrians and / or occupants of the vehicle can notice the railing component in a timely manner.

[0016] Optionally, the second warning element is a second light source assembly, the railing element is made of transparent material and has a hollow mounting part in its middle, and the second light source assembly is disposed in the hollow mounting part.

[0017] Optionally, the bottom of the first warning member is provided with a first waterproof component, which can prevent rainwater from flowing into the installation receiving component when the railing member is retracted into the installation receiving component.

[0018] Optionally, the outer peripheral wall of the railing member is provided with a second waterproof component, which can prevent rainwater from flowing into the mounting housing when the railing member extends out of the mounting housing.

[0019] Optionally, the mounting housing is cylindrical, and the second waterproof component is made of a flexible material and has two states. When the railing component extends out of the mounting housing, the second waterproof component is in an unfolded state, at which time the diameter of the second waterproof component is greater than the outer diameter of the mounting housing. When the railing component retracts into the mounting housing, the second waterproof component is in a retracted state, at which time the diameter of the second waterproof component is less than or equal to the inner diameter of the mounting housing.

[0020] Optionally, the bottom of the mounting housing is provided with a drainage hole, the side wall of the mounting housing is provided with a wire through hole, the lifting component is a cylinder, and the power component is an air pump.

[0021] A tidal flow lane divider includes multiple liftable barrier devices, which are interconnected via air ducts.

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention combines a lifting component with a power component to flexibly adjust the height of the barrier. This allows the barrier to quickly adjust lane opening and closing based on changes in traffic flow and lane usage demand. For example, during peak traffic hours, the barrier can rise as a roadblock, restricting the use of certain lanes and ensuring more lane resources flow to areas with higher traffic volume. During off-peak hours, the barrier retracts into its mounting housing, releasing lane resources and improving road capacity. Through this dynamic adjustment, the lane resources of the tidal flow lane are utilized efficiently, preventing some lanes from being idle during specific periods and improving overall road efficiency. Furthermore, the mounting housing is located below ground, ensuring the device's concealment and aesthetics, while preventing external interference with the lifting device and extending its lifespan. Overall, this liftable barrier device can flexibly adjust lane status according to the usage needs of tidal flow lanes, optimizing traffic flow, improving safety and efficiency, avoiding delays or accidents caused by traffic congestion, and ensuring efficient, easy-to-use, and safe road operation.

[0039] Examples of embodiments of this utility model Figures 1-5The diagram illustrates a liftable barrier device, comprising a barrier component 100, a lifting assembly 200, a mounting housing 300, and a power assembly 400. The barrier component 100 can be used as a road barrier. The lifting assembly 200 includes a main body 210 and a lifting part 220, which is connected to the barrier component 100 and used to lift the barrier component 100. The mounting housing 300 is disposed below the ground, and the lifting assembly 200 is disposed within the mounting housing 300. The power assembly 400 is connected to the lifting assembly 200 and provides power to the lifting assembly 200, enabling the lifting part 220 to lift. When the barrier component 100 is needed for use as a road barrier, the power assembly 400 provides power to the lifting assembly 200, and the lifting part 220 of the lifting assembly 200 causes the barrier component 100 to extend out of the mounting housing 300. When the guardrail 100 is not needed for roadblock use, the power component 400 provides power to the lifting component 200. The lifting part 220 of the lifting component 200 drives the guardrail 100 to retract into the mounting container 300. Furthermore, in use, a mounting hole is first drilled in the ground to place the mounting container. The combination of the lifting component 200 and the power component 400 allows for flexible adjustment of the height of the guardrail 100, enabling the guardrail to rise or retract as needed, facilitating use in different scenarios. It can act as a roadblock to ensure road safety, and can also automatically retract when not needed, saving space and improving road traffic efficiency. Secondly, the mounting container 300 hides the lifting component 200 and the power component 400 below the ground, which not only improves the aesthetics of the device but also effectively avoids environmental interference or human damage, extending the service life of the equipment. Furthermore, the power provided by the power component 400 ensures the smoothness and efficiency of the lifting operation, reduces the complexity of manual operation, improves the automation level of the system, and makes the equipment easier and more reliable to use. In this embodiment, the lifting component 200 is a cylinder and the power component 400 is an air pump. In some embodiments, the lifting component 200 may be a hydraulic lift and the power component 400 may be a hydraulic pump.

[0040] See Figures 1-5In this embodiment, a first warning element 110 is provided on the top of the guardrail component 100. The first warning element 110 is used to warn pedestrians and / or vehicle occupants, enabling them to promptly notice the guardrail component 100. Furthermore, by providing the first warning element 110 on the top of the guardrail component 100, the alertness of pedestrians and vehicle occupants can be effectively enhanced, ensuring that they can promptly notice the presence of the guardrail when approaching, thereby avoiding potential collisions or accidents. Especially in low visibility or nighttime conditions, it can provide additional visual reminders, improving road safety. At the same time, the warning element can improve the visibility and recognizability of the guardrail, reducing misoperation or neglect caused by invisibility or inconspicuousness, enhancing the overall safety of traffic facilities, and reducing personal and property losses. Through this design, the guardrail not only serves as a physical barrier but also prevents accidents by providing early warnings, improving the safety of road and traffic facility use.

[0041] See Figures 1-5 In this embodiment, the first warning element 110 includes a first light source assembly 111 disposed on the top of the railing 100 and a lampshade 112 sleeved over the first light source assembly 111. The lampshade 112 is made of red transparent material. Furthermore, by setting the first warning element 110 on the top of the railing 100 and combining it with the lampshade 112 made of red transparent material, this utility model provides a more conspicuous and clear warning effect for pedestrians and people inside vehicles. The red transparent material of the lampshade 112 makes the light more penetrating and warning under night or low visibility conditions, which can effectively attract attention and avoid accidents caused by inconspicuous railings. In addition, the design of the lampshade 112 can protect the light source assembly, extend its service life, and ensure uniform light distribution, avoiding damage or interference caused by light source exposure. Specifically, the first light source assembly 111 is an LED light.

[0042] See Figures 1-5In this embodiment, a second warning element 120 is provided on the outside or inside of the railing member 100. The second warning element 120 is used to warn pedestrians and / or occupants of vehicles, allowing them to notice the railing member 100 in a timely manner. Further, the second warning element 120 is a second light source assembly 121. The railing member 100 is made of transparent material and has a hollow mounting portion in its center. The second light source assembly 121 is disposed within the hollow mounting portion. By providing the second warning element 120 on the outside or inside of the railing member 100 and placing the second light source assembly 121 within the hollow mounting portion, the warning effect is further enhanced. The railing member 100 is made of transparent material. This design allows the light from the second light source component 121 to penetrate better, enhancing the visibility of the warning. Whether during the day or night, it effectively alerts pedestrians and vehicle occupants to the presence of the railing, reducing the risk of accidental collisions. The hollow mounting section not only provides a safe space for the second light source component 121 but also ensures the overall integrity and aesthetics of the railing component 100. It also protects the light source component from interference or damage from the external environment. Furthermore, the second light source component 121 provides multiple warnings at different locations on the railing component 100, further increasing the coverage and timeliness of the warnings, and improving the safety performance and operability of the equipment. Specifically, the second light source component 121 is a light strip.

[0043] See Figures 1-5 In this embodiment, a first waterproof component 140 is provided at the bottom of the first warning component 110. When the railing component 100 retracts into the mounting housing 300, the first waterproof component 140 can prevent rainwater from flowing into the mounting housing 300. Furthermore, by providing the first waterproof component 140 at the bottom of the first warning component 110, the durability and long-term performance of the railing device are effectively improved. When the railing component 100 retracts into the mounting housing 300, the first waterproof component 140 can effectively prevent rainwater from entering the mounting housing 300, avoiding moisture from corroding or damaging internal components such as the lifting assembly 200 and the power assembly 400, thereby extending the service life of the equipment. In addition, the waterproof design can also ensure that the system can operate stably under various weather conditions, reduce the occurrence of failures caused by environmental factors, improve the reliability and maintenance convenience of the system, and make the railing device more suitable for outdoor or harsh climate environments, ensuring safety and functionality in long-term use and reducing unnecessary maintenance costs.

[0044] In this embodiment, a second waterproof component 150 is provided on the outer peripheral wall of the railing component 100. When the railing component 100 extends into the mounting housing 300, the second waterproof component 150 can prevent rainwater from flowing into the mounting housing 300. Furthermore, the mounting housing 300 is cylindrical, and the second waterproof component 150 is made of a flexible material and has two states: when the railing component 100 extends into the mounting housing 300, the second waterproof component 150 is in an unfolded state, at which time the diameter of the second waterproof component 150 is larger than the outer diameter of the mounting housing 300; when the railing component 100 retracts into the mounting housing 300, the second waterproof component 150 is in a retracted state, at which time the diameter of the second waterproof component 150 is less than or equal to the outer diameter of the mounting housing 300. Specifically, by setting a second waterproof component 150 on the outer peripheral wall of the railing component 100 and using a flexible material, the railing component 100 can flexibly adapt to different working states during extension and retraction, providing effective waterproof protection. When the railing component 100 extends out of the mounting housing 300, the second waterproof component 150 unfolds, forming a waterproof barrier with a diameter larger than the outer diameter of the mounting housing 300, preventing rainwater from entering the mounting housing 300, thereby protecting the internal lifting and power components 400 from moisture damage. The use of flexible materials ensures that the waterproof component can retract when the railing component 100 retracts, reducing the space occupied, ensuring the stability and efficiency of the equipment under various climatic conditions, reducing malfunctions and maintenance needs caused by rainwater infiltration, and improving the overall performance of the railing device.

[0045] In this embodiment, a drainage hole 310 is provided at the bottom of the mounting housing 300, and a wire-passing hole 320 is provided on the side wall of the mounting housing 300. Furthermore, by providing the drainage hole 310 at the bottom and the wire-passing hole 320 on the side wall of the mounting housing 300, effective drainage is provided, which helps to enhance the durability and stability of the equipment. The drainage hole 310 can prevent rainwater or other liquids from accumulating inside the mounting housing 300, avoiding corrosion, damage, or rust of internal components due to water accumulation. Especially during long-term use, this helps to improve the reliability of the equipment and extend its service life. At the same time, the presence of the wire-passing hole 320 facilitates the installation and arrangement of wires or ventilation pipes, ensuring that the electrical components of the system are not excessively affected by the environment during operation. This not only improves the safety and waterproof performance of the system but also optimizes the convenience of equipment installation and maintenance, reduces malfunctions caused by water accumulation or wiring problems, and improves the overall working efficiency and stability of the device.

[0046] In this embodiment, a reversible lane separation device includes multiple liftable barrier devices, which are interconnected via air ducts (not shown in the figure). This interconnection allows the barrier components of each device to rise or retract simultaneously, dynamically adjusting the lane's direction and width based on traffic flow and time of day to optimize road resource utilization, alleviate traffic congestion, and improve traffic efficiency. Specifically, the reversible lane separation device can change lane direction during peak hours using the liftable barrier devices, allowing more lane resources to flow towards areas with higher traffic volume. During off-peak hours, the lanes return to their original state, ensuring road flexibility and safety. The reversible lane separation device can be managed in conjunction with real-time traffic data and a control system, flexibly allocating lanes according to traffic demand at different times, reducing traffic bottlenecks, and improving road capacity.
