Description

Technical Field

[0001] This utility model relates to the field of road sign technology, and in particular to an operational road sign. Background Technology

[0002] The development of operational road sign technology has evolved from simple to complex, and from static to dynamic. Early operational road signs were primarily static metal plates with simple text and graphics printed on them. With increasing traffic volume and construction complexity, operational road signs gradually evolved into electronic displays that could update information in real time based on actual conditions. In recent years, as highway construction has shifted from large-scale new construction to primarily routine maintenance, operational road sign technology has also developed accordingly towards greater flexibility, safety, and efficiency.

[0003] Currently, road signs are mainly used in routine maintenance and repair work on highways. Maintenance work is characterized by being carried out without disrupting traffic, and in most cases, it requires road closures. Existing road construction signs typically require manual installation and removal, a process carried out according to specific national and industry standards. The installation process usually includes determining the construction area, selecting the appropriate sign type, installing the signs in the designated locations, and regular inspection and maintenance. After construction is completed, these signs must be removed in reverse order.

[0004] Although existing road construction sign technology has played an important role in ensuring construction safety, there is still a critical problem that urgently needs to be solved: when operational road signs are in use, they are usually installed in the area of ​​use for a long time, and the sign face is usually set facing the direction of oncoming traffic. However, the duration of maintenance construction varies. If the sign face is set facing the direction of oncoming traffic for a long time, it will seriously affect the normal operation of the road. Utility Model Content

[0005] The main purpose of this utility model is to propose an operational road sign, which aims to solve the technical problem that, in the use of related technologies, operational road signs are usually installed in the area of ​​use for a long time, and the sign face is usually set facing the direction of oncoming traffic. However, the duration of maintenance and construction varies. If the sign face is set facing the direction of oncoming traffic for a long time, it will seriously affect the normal operation of the road.

[0006] To achieve the above objectives, this utility model proposes an operational road sign, which is installed on one side of an operational road, the road forming a lane extending in a first direction, comprising:

[0007] A base, which is installed on the road and located on one side of the driving lane;

[0008] A rotating support base, the rotating support base being mounted on the base; and,

[0009] A signboard, wherein the signboard is mounted on the top of the rotating support base, and one side of the signboard forms a sign surface;

[0010] The rotating support can drive the sign to rotate relative to the base, so that the sign face can be switched between a first state facing the driving lane and a second state coinciding with the driving lane along the first direction.

[0011] In one embodiment, the rotating support includes:

[0012] A connecting seat is mounted on the base, and the top of the connecting seat extends upward to form a rotation mounting position;

[0013] A rotating assembly, which is mounted on the rotating mounting position;

[0014] A connecting post is mounted on the rotating assembly, and the sign is mounted on the top of the connecting post. The rotating assembly can drive the connecting post to rotate the sign so that the sign face can be switched between a first state facing the driving lane and a second state coinciding with the driving lane along the first direction.

[0015] In one embodiment, the rotating component includes:

[0016] A drive motor, the drive motor being mounted on the rotary mounting position, with the output shaft of the drive motor facing upwards; and...

[0017] A rotary transmission component is mounted on the connecting column and is driven by the output shaft of the drive motor. The drive motor can drive the rotary transmission component to rotate the connecting column.

[0018] In one embodiment, the rotating assembly further includes a remote control terminal, which is communicatively connected to the drive motor.

[0019] In one embodiment, the connector includes:

[0020] A support column, the support column being mounted on top of the base, the top of the support column forming the rotation mounting position; and,

[0021] Multiple support blocks are distributed circumferentially around the outer periphery of the support column, and all support blocks are welded to the support column and the base.

[0022] In one embodiment, the rotating support base further includes a solar panel, which is mounted on the connecting base.

[0023] In one embodiment, the rotating support base further includes a support frame, which is welded to the connecting seat, and the solar panel is mounted on the support frame.

[0025] In one embodiment, the road sign is any one of a speed limit sign, a construction triangle sign, or a construction length sign.

[0026] In one embodiment, the base is detachably connected to the road.

[0027] The technical solution of this utility model involves setting up a base, a rotating support, and a sign. In use, the base is installed on the road and located on one side of the driving lane, the rotating support is installed on the base, and the sign is installed on the top of the rotating support, with one side of the sign forming a sign surface. This allows the rotating support to drive the sign to rotate relative to the base, enabling the sign surface to switch between a first state facing the driving lane and a second state coinciding with the driving lane along a first direction. This allows the utility model to utilize the rotating support to drive the sign to rotate, enabling the sign surface to switch between the first state facing the driving lane and the second state coinciding with the driving lane along a first direction. Furthermore, this eliminates the need for the sign surface to always face the oncoming traffic direction, thus achieving the function of normal road control when traffic control is required, and ensuring normal road operation when traffic control is not needed.

[0038] This utility model proposes an operational road sign.

[0039] Please see Figures 1 to 3 In one embodiment of this utility model, an operating road 400 sign 300 is installed on one side of an operating road 400. The road 400 forms a lane 410 extending along a first direction. The sign includes a base 100, a rotating support 200, and a sign 300. The base 100 is installed on the road 400 and located on one side of the lane 410. The rotating support 200 is installed on the base 100. The sign 300 is installed on the top of the rotating support 200, and one side of the sign 300 forms a sign surface 310. The rotating support 200 can drive the sign 300 to rotate relative to the base 100, so that the sign surface 310 can be switched between a first state facing the lane 410 and a second state coinciding with the lane 410 along the first direction.

[0040] In one embodiment, the present invention provides an operating road 400 sign 300, which is installed on one side of an operating road 400. The road 400 forms a lane 410 extending in a first direction, and the sign 300 includes a base 100, a rotating support 200, and a sign 300 body.

[0041] The base 100 is installed on the road 400 and located on one side of the carriageway 410. Specifically, the base 100 can be made of cast concrete or metal. Expansion bolts can be installed at the bottom of the base 100 to fix it to the road surface of the road 400, ensuring the stability of the base 100. The top of the base 100 can be provided with a mounting surface for installing the rotating support 200.

[0042] A rotating support 200 is mounted on the base 100. The rotating support 200 may include a base 110 and a rotating shaft. The base 110 is fixedly connected to the mounting surface of the base 100, and the rotating shaft is vertically arranged and rotatably connected to the base 110. A connector for mounting the sign 300 body may be provided at the top end of the rotating shaft. The rotating support 200 also includes a drive motor 240, which is drively connected to the rotating shaft for driving the rotating shaft to rotate.

[0043] The sign 300 body is mounted on the top of the rotating support 200, specifically on the connector at the top of the rotating shaft. One side of the sign 300 body forms a sign surface 310, on which traffic signs, warning information, and other content can be displayed. The sign 300 body can be made of metal or plastic sheet, and its surface can be coated with reflective material to improve nighttime visibility.

[0044] The rotating support 200 can drive the sign 300 body to rotate relative to the base 100, so that the sign surface 310 can be switched between a first state facing the traffic lane 410 and a second state coinciding with the traffic lane 410 along a first direction. Specifically, when the sign 300 is needed, the drive motor 240 drives the rotating shaft to rotate, so that the sign surface 310 faces the traffic lane 410, which is the first state. When the sign 300 is not needed, the drive motor 240 drives the rotating shaft to rotate 90 degrees again, so that the sign surface 310 is parallel to the traffic lane 410, which is the second state.

[0045] Taking a highway construction site as an example, this paper describes in detail from a machine's perspective how to apply the aforementioned 400-300 roadway sign, based on the structure described above.

[0046] First, select a suitable location on the shoulder of the highway and install the base 100. The base 100 is fixedly connected to the road surface using expansion bolts. Then, fix the base 110 of the rotating support 200 to the mounting surface of the base 100. Next, install the sign 300 body onto the connector at the top of the rotating support 200.

[0047] When road construction is required at 400, the control system issues a command, and the drive motor 240 rotates the rotating shaft, so that the sign face 310 of the sign 300 faces the driving lane 410, which is the first state. At this time, the driver can clearly see the construction warning information on the sign 300.

[0048] After construction is completed, the control system issues another command, driving motor 240 to rotate the rotating shaft 90 degrees, making the sign surface 310 of the sign 300 body parallel to the driving lane 410, thus entering the second state. At this time, the sign 300 will not interfere with normal traffic.

[0049] Through this rotatable structural design, the road 400 sign 300 of this utility model can flexibly switch states according to actual needs. It can serve as an effective warning during construction and reduce the impact on normal traffic when not under construction, thus improving the practicality and adaptability of the road 400 sign 300. At the same time, since the sign 300 can remain in place without frequent disassembly, it also improves efficiency and safety.

[0050] In this embodiment, by setting up a base 100, a rotating support 200, and a sign 300, in use, the base 100 is installed on the road 400 and located on one side of the driving lane 410, the rotating support 200 is installed on the base 100, and the sign 300 is installed on the top of the rotating support 200, with one side of the sign 300 forming a sign surface 310. This allows the rotating support 200 to drive the sign 300 to rotate relative to the base 100, so that the sign surface 310 can be rotated between a first state facing the driving lane 410 and a second state coinciding with the driving lane 410 along a first direction. The switching allows the sign 300 to rotate using the rotating support 200, enabling the sign surface 310 to switch between a first state facing the driving lane 410 and a second state coinciding with the driving lane 410 along a first direction. This eliminates the need for the sign surface 310 to always face the direction of oncoming traffic, thus achieving both normal traffic control when needed and ensuring normal operation of the road when no traffic control is required.

[0051] In one embodiment, the rotating support 200 includes a connecting seat 210, a rotating component 220, and a connecting column 230. The connecting seat 210 is mounted on the base 100, and the top of the connecting seat 210 extends upward to form a rotating mounting position. The rotating component 220 is mounted on the rotating mounting position, and the connecting column 230 is mounted on the rotating component 220. A sign 300 is mounted on the top of the connecting column 230. The rotating component 220 can drive the connecting column 230 to rotate the sign 300, so that the sign surface 310 can be switched between a first state facing the driving lane 410 and a second state coinciding with the driving lane 410 along a first direction.

[0052] Specifically, the connector 210 can be made of metal, such as aluminum alloy or stainless steel. Multiple mounting holes can be provided at the bottom of the connector 210 for fixed connection to the base 100 via bolts. The rotating mounting position formed by the upward extension of the top of the connector 210 can be cylindrical, and its outer circumferential surface can be provided with grooves or protrusions for mating with the rotating assembly 220.

[0053] The rotating assembly 220 may include a bearing, a gear transmission mechanism, and a drive motor 240. The bearing is mounted on a rotating mounting position. The gear transmission mechanism includes a driving gear and a driven gear. The driving gear is connected to the output shaft of the drive motor 240, and the driven gear is fixedly connected to the connecting column 230. The drive motor 240 may be a stepper motor or a servo motor to achieve precise control.

[0054] The connecting post 230 can be a hollow structure, with its bottom fixedly connected to the driven gear and its top equipped with a mounting plate for mounting the sign 300. Wiring can be arranged inside the connecting post 230 to power the lighting devices or electronic display screen on the sign 300.

[0055] In practical applications, when the sign 300 is needed, the control system issues a command, the drive motor 240 starts, and drives the connecting column 230 to rotate through the gear transmission mechanism, so that the sign surface 310 faces the driving lane 410, which is the first state. When the sign 300 is no longer needed, the drive motor 240 starts again, driving the connecting column 230 to rotate 90 degrees, so that the sign surface 310 is parallel to the driving lane 410, which is the second state.

[0056] This structural design offers the following advantages: First, the rotation of the sign 300 via the rotating component 220 is more convenient and precise than manual adjustment. Second, the fixed connection between the connecting seat 210 and the base 100 enhances the stability of the entire structure, enabling it to withstand significant wind loads. Third, the hollow design of the connecting column 230 facilitates wiring and improves structural integration. Finally, the control system allows for remote control and automated operation of the sign 300, improving efficiency.

[0057] In this embodiment, the rotating support base 200 structure, through the ingenious cooperation of the connecting base 210, the rotating component 220, and the connecting column 230, achieves reliable support and flexible rotation of the sign 300. This structure not only meets the warning requirements during road 400 construction but also minimizes the impact on normal traffic when not under construction, thus effectively solving the technical problem of road 400 signs 300 occupying visual space for extended periods.

[0058] In one embodiment, the rotating assembly 220 includes a drive motor 240 and a rotation transmission component 250. The drive motor 240 is mounted in a rotation mounting position with its output shaft facing upward. The rotation transmission component 250 is mounted on a connecting column 230 and is in transmission cooperation with the output shaft of the drive motor 240. The drive motor 240 can drive the rotation transmission component 250 to rotate the connecting column 230.

[0059] Specifically, the drive motor 240 can be a stepper motor or a servo motor to achieve precise control. The housing of the drive motor 240 can be fixed to a rotary mounting position with bolts, and its output shaft extends vertically upward. The power and control cables of the drive motor 240 can be led out through the pre-reserved wire groove inside the connector 210 and connected to the control system.

[0060] The rotary transmission component 250 can be a gear or a pulley. When a gear is used, a large gear can be fixedly installed at the bottom of the connecting column 230, and this large gear meshes with a small gear on the output shaft of the drive motor 240. When a pulley is used, a large pulley can be fixedly installed at the bottom of the connecting column 230, and this large pulley is connected to a small pulley on the output shaft of the drive motor 240 via a synchronous belt. Both transmission methods can achieve a large reduction ratio, increasing the rotational torque of the sign 300.

[0061] The connecting post 230 may have a hollow structure, with its bottom fixedly connected to the rotary transmission component 250 and its top equipped with a mounting plate for mounting the sign 300. Wiring may be arranged inside the connecting post 230 to power the lighting devices or electronic display screen on the sign 300.

[0062] In practical applications, when the sign 300 is needed, the control system issues a command, starting the drive motor 240. This drives the connecting post 230 to rotate via the rotational transmission component 250, aligning the sign surface 310 with the driving lane 410, thus achieving the first state. When the sign 300 is no longer needed, the drive motor 240 restarts, rotating the connecting post 230 90 degrees, making the sign surface 310 parallel to the driving lane 410, thus achieving the second state. The entire process is automated and requires no manual intervention.

[0063] This structural configuration offers the following advantages: First, the drive motor 240 is directly mounted on the rotary mounting position, resulting in a compact structure, reduced transmission links, and improved transmission efficiency. Second, the upward-facing output shaft of the drive motor 240 facilitates direct engagement with the rotary transmission component 250 at the bottom of the connecting column 230, simplifying the transmission structure. Third, by selecting a suitable rotary transmission component 250, a larger reduction ratio can be achieved, increasing the rotational torque of the sign 300 and ensuring reliable operation even in harsh environments such as strong winds. Finally, this structure facilitates maintenance; the drive motor 240 can be inspected or replaced simply by disassembling the connecting column 230.

[0064] In this embodiment, the rotating component 220 structure, through the ingenious cooperation of the drive motor 240 and the rotating transmission component 250, achieves precise control and reliable rotation of the sign 300. This structure not only meets the warning requirements during road construction, but also allows for quick switching to a non-interference state when not under construction. This effectively solves the technical problem of traditional fixed signs 300 occupying visual space for extended periods, thus improving the practicality and adaptability of the road sign 300.

[0065] In one embodiment, the rotating assembly 220 further includes a remote control terminal, which is communicatively connected to the drive motor 240.

[0066] Specifically, the remote control terminal can be a handheld device, such as a dedicated remote control or a smartphone. The remote control terminal has a built-in wireless communication module, such as a Bluetooth module or a Wi-Fi module. Correspondingly, the drive motor 240 is equipped with a corresponding wireless receiver module to receive control commands sent by the remote control terminal.

[0067] The remote control terminal is equipped with a user interface, including a display screen and input buttons. The display screen can show the current status of the sign 300 in real time, such as the first state facing the driving lane 410 or the second state coinciding with the driving lane 410. The input buttons allow the operator to send control commands, such as switching states or adjusting angles.

[0068] In practical applications, when the sign 300 is needed, the operator can send a command via the remote control terminal. Upon receiving the command, the drive motor 240 starts and rotates the connecting column 230, causing the sign surface 310 to face the driving lane 410, which is the first state. When the sign 300 is no longer needed, the operator again sends a command via the remote control terminal, causing the drive motor 240 to rotate the connecting column 230 by 90 degrees, making the sign surface 310 parallel to the driving lane 410, which is the second state.

[0069] The remote control terminal can also be equipped with a timer function, allowing operators to preset the rotation time of the sign 300. For example, it can be set to automatically rotate the sign surface 310 to the first state during the morning and evening peak hours each day, and keep it in the second state at other times. This automated operation can greatly improve the efficiency of the sign 300.

[0070] In addition, the remote control terminal can be connected to the central control system to achieve remote monitoring and management. The central control system can manage multiple road signs simultaneously and uniformly schedule the status of each sign according to traffic conditions and construction needs.

[0071] This remote control method has the following advantages: First, it eliminates the need for operators to be physically present on-site to control the rotation of the sign 300, improving operational convenience and safety. Second, wireless communication technology avoids the installation complexity and maintenance difficulties that can arise from wired connections. Third, the user interface of the remote control terminal is intuitive and easy to use, reducing operator training costs. Finally, combined with timing functions and a central control system, it enables intelligent management of the sign 300, improving road management efficiency.

[0072] In this embodiment, the remote control terminal provides a flexible and convenient control method for the rotating component 220. Through wireless communication technology and a user-friendly interface, operators can remotely control the rotation state of the sign 300, achieving intelligent management. This method not only improves the utilization efficiency of the sign 300 but also reduces the safety risks of manual operation, effectively solving the technical problem of inconvenient adjustment of traditional fixed sign 300s, and providing a more advanced and efficient solution for road management.

[0073] In one embodiment, the connecting seat 210 includes a support column 260 and a plurality of support blocks 270. The support column 260 is mounted on the top of the base 100, and the top of the support column 260 forms a rotation mounting position. The plurality of support blocks 270 are distributed circumferentially around the outer periphery of the support column 260, and all support blocks 270 are welded to the support column 260 and the base 100.

[0074] In one embodiment, the rotating support 200 further includes a solar panel 280, which is mounted on the connecting seat 210. The rotating support 200 also includes a support frame 281, which is welded to the connecting seat 210, and the solar panel 280 is mounted on the support frame 281.

[0075] Specifically, the support frame 281 can be made of lightweight, high-strength materials, such as aluminum alloy or stainless steel. The structure of the support frame 281 can be triangular or trapezoidal to provide sufficient strength and stability. The bottom of the support frame 281 is securely connected to the connecting seat 210 by welding to ensure that it will not loosen or fall off under harsh weather conditions.

[0076] The top of the support frame 281 forms a platform for mounting the solar panel 280. This platform can be designed with an adjustable angle to adjust the tilt angle of the solar panel 280 according to the latitude of the installation location and seasonal changes, maximizing solar energy absorption efficiency. Multiple mounting holes can be pre-drilled on the platform to facilitate the fixing of solar panels 280 of different sizes.

[0077] The solar panel 280 is mounted on the platform of the support frame 281 using bolts or clips. During installation, rubber gaskets can be added between the solar panel 280 and the support frame 281 to reduce vibration and improve waterproofing. The output wires of the solar panel 280 can be led to the connector 210 through the pre-reserved wire groove inside the support frame 281, ensuring neat and protected wiring.

[0078] This structural configuration has the following advantages:

[0079] First, the solar panel 280 is separated from the connector 210 by the support frame 281, avoiding potential interference that might occur if the solar panel 280 were directly installed on the connector 210. The presence of the support frame 281 provides more installation space for the solar panel 280, allowing the use of larger solar panels 280 and increasing power generation.

[0080] Secondly, the adjustability of the support frame 281 allows the solar panel 280 to always maintain the optimal working angle, ensuring that the efficiency of the solar panel 280 is not affected regardless of how the sign 300 rotates. This flexibility greatly improves the system's adaptability to different geographical locations and seasons.

[0081] Furthermore, the welded connection method of support frame 281 ensures the stability and durability of the entire structure. Compared with bolted connections, welded connections are more resistant to long-term vibration and the effects of severe weather, reducing maintenance requirements.

[0082] Furthermore, the presence of the support frame 281 provides additional possibilities for system functional expansion. For example, monitoring devices such as wind speed sensors and temperature sensors can be installed on the support frame 281 to provide more environmental data support for the intelligent control of the sign 300.

[0083] In practical applications, when it is necessary to install or replace the solar panel 280, maintenance personnel can operate directly on the support frame 281 without touching the connector 210 or other core components, which greatly simplifies the maintenance process and improves work efficiency and safety.

[0084] The support frame 281 structure in this embodiment provides a stable, flexible, and easy-to-maintain platform for the installation of the solar panel 280. By separating the solar panel 280 from the connecting seat 210, not only is the space utilization and energy efficiency of the system optimized, but the stability and maintainability of the entire device are also improved. This structural solution effectively solves the space limitations and installation difficulties faced by traditional road 400 signboards 300 when integrating renewable energy systems, providing reliable technical support for intelligent and green road 400 signboard systems.

[0085] In one embodiment, a waterproof electrical box 290 is also included, which is electrically connected to the drive motor 240 and the solar panel 280 via wires.

[0086] Specifically, the waterproof electrical box 290 can be made of high-strength engineering plastics or stainless steel, possessing excellent waterproof, dustproof, and corrosion-resistant properties. The structure of the waterproof electrical box 290 may include a box body, a sealing cover, and a waterproof sealing ring. Multiple compartments can be set inside the box body to house different electronic components. The sealing cover is securely connected to the box body with bolts, and the waterproof sealing ring is installed between the contact surfaces of the sealing cover and the box body to ensure the overall airtightness of the electrical box.

[0087] The waterproof electrical box 290 can house electrical components such as a charge / discharge controller, battery pack, and inverter. The charge / discharge controller manages the power generation of the solar panel 280 and the charging / discharging process of the battery, preventing overcharging or over-discharging. The battery pack can be a lithium-ion battery or a lead-acid battery, used to store the electrical energy generated by the solar panel 280. The inverter converts the direct current from the battery into alternating current required to drive the motor 240.

[0088] The wires connecting the waterproof electrical box 290 and the drive motor 240 can be made of wear-resistant, waterproof multi-core cable, connected to the electrical box and motor through a waterproof connector. The wire specifications should be selected according to the power and voltage requirements of the motor to ensure safe and reliable power transmission.

[0089] The wires connecting the waterproof electrical box 290 and the solar panel 280 can be made of dedicated photovoltaic cables, which have excellent weather resistance and UV resistance. These wires are also connected to the electrical box and solar panel 280 through waterproof connectors to ensure long-term stable operation in outdoor environments.

[0090] In practical applications, the waterproof electrical box 290 can be installed inside or at the bottom of the connector 210, close to the drive motor 240, to shorten the wire length and reduce power loss. The installation location of the electrical box should facilitate inspection and maintenance by maintenance personnel, while not affecting the normal rotation of the sign 300.

[0091] This structural configuration has the following advantages:

[0092] First, centralized management of electrical components simplifies system wiring and maintenance. All critical electrical components are housed in a waterproof environment, significantly improving system reliability and durability.

[0093] Secondly, the use of the waterproof electrical box 290 effectively protects electrical components from rain, dust, and other environmental factors, extending the service life of the entire system. It ensures the normal operation of the system even under harsh weather conditions.

[0094] Furthermore, the charge / discharge controller and battery pack inside the waterproof electrical box 290 achieve a balance between solar power generation and electrical load, enabling the system to operate continuously 24 hours a day, unaffected by sunlight conditions.

[0095] Furthermore, the modular design of the waterproof electrical box 290 facilitates future upgrades and expansions. For example, a larger capacity battery can be added as needed, or a remote monitoring module can be added without changing the overall system structure.

[0096] The waterproof electrical box 290 in this embodiment provides a centralized, safe, and reliable power management solution for the entire 400 km / h road sign 300 system. By concentrating key electrical components in a waterproof environment, not only is the safety and reliability of the system improved, but the installation and maintenance process is also simplified. This structural design effectively solves the problem of the electrical system of traditional 400 km / h road signs 300 being easily damaged in outdoor environments, providing a solid technical foundation for intelligent, long-life 400 km / h road sign systems.

[0097] The operating road sign 300 is any one of the following: speed limit sign, construction triangle sign 300, or construction length sign 300.

[0098] In one embodiment, the base 100 is detachably connected to the road 400.

[0099] It can be further clarified that, in this embodiment, the example base 100 includes a base 110, which is rectangular. Bolt holes 120 are formed at the corners of the rectangular base 110, and multiple walking components are arranged circumferentially around the outer periphery of the base 100. The walking components can switch between an extended state extending out of the base 110 and a retracted state stored in the base 110. The walking components include a hinge seat 130 that is hinged to the base 110. The hinge seat 130 can rotate relative to the base 110. A walking wheel 140 is installed at the end of the hinge seat 130 away from the base 110. When the hinge seat 130 rotates relative to the base 110 so that the walking wheel 140 is exposed on the base 110, the multiple walking wheels 140 can drive the road 400 sign 300 to move. A through hole 150 is formed at the position of the rotation axis of the walking wheel 140, penetrating both sides of the walking wheel 140. When it is necessary to fix the road sign 300 to the shoulder of the road 400, each of the traveling wheels 140 can be rotated so that the side of the traveling wheel 140 is in contact with the shoulder, so that the expansion bolts can pass through the through hole 150 in the middle of the traveling wheel 140 and be fixed to the shoulder. Of course, when it is necessary to fix the base 110 to the flat road 400, the traveling wheel 140 can be rotated through the provided hinge seat 130 so that its through hole 150 is aligned with the bolt hole 120 on the base 110, thereby realizing the function of fixing the traveling wheel 140.

[0100] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
