Description

Technical Field

[0001] This invention relates to the field of road traffic facilities technology, and in particular to a self-moving guardrail. Background Technology

[0002] With urban economic development, traffic congestion has become increasingly serious, especially the pronounced tidal traffic phenomenon. Every morning, traffic flow is high heading into the city and low heading out; conversely, in the evening, traffic flow is high heading out and low heading in. This uneven distribution of traffic flow makes traditional fixed lane configurations insufficient to meet traffic demand, easily leading to congestion in some lanes and low utilization of others. Therefore, facilities capable of flexibly adjusting lanes according to traffic flow changes are needed. Against this backdrop, tidal lanes and their corresponding facilities have emerged.

[0003] Existing self-moving guardrails designed for tidal changes typically move automatically to a designated location during operation. However, due to the large area of ​​the guardrails and the fact that the power source is located on the connecting poles on both sides, strong winds and other factors can cause them to tip over. If the guardrails tip over during tidal changes, not only will they be unable to reposition themselves smoothly, but they will also impact the road surface, creating roadblocks and disrupting traffic, severely impacting traffic efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a self-moving guardrail to alleviate the problem that guardrails in the prior art are prone to tipping over during tidal movement.

The transmission component can extend or retract into the through groove under the action of the drive component, and the support component can extend or retract into the storage groove under the action of the transmission component.

[0006] Furthermore, the drive assembly includes an electric telescopic rod and a control unit. The top end of the electric telescopic rod is fixedly connected to the inner top wall of the guardrail connecting rod, the telescopic end of the electric telescopic rod is connected to the transmission assembly, and the control unit is signal-connected to the electric telescopic rod.

[0007] Furthermore, the transmission assembly includes a first transmission part and a second transmission part. The first transmission part includes a transmission wheel, a connecting block, and a first half gear. The top of the transmission wheel is fixedly connected to the telescopic end of the electric telescopic rod. The transmission wheel can extend or retract into the through slot under the action of the electric telescopic rod. The telescopic end of the electric telescopic rod passes through the connecting block and is fixedly connected to the connecting block.

[0008] Furthermore, the second transmission part includes a second half gear, the support assembly includes a support rod and a rotating wheel, the second half gear is hinged to the storage groove, the second half gear is meshed with the first half gear, one end of the support rod is fixedly connected to the side of the second half gear, and the other end is fixedly connected to the rotating wheel, and the support rod and the rotating wheel can extend or retract into the storage groove under the action of the second half gear.

[0009] Furthermore, the support rod includes a first rod segment and a second rod segment connected in an L-shape. The first rod segment is fixedly connected to the side of the second half gear, and the second rod segment is fixedly connected to the rotating wheel.

[0010] Furthermore, a support column connects the first rod segment and the second rod segment, and the support column, the first rod segment, and the second rod segment form a triangular structure.

[0011] Furthermore, it also includes a support frame fixedly connected to the road surface, with the control unit disposed on the support frame.

[0012] Furthermore, the control unit includes a camera and a sensor. The camera is fixedly mounted on the top of the support frame, and the sensor is fixedly mounted on the side of the support frame. The sensor is connected to the camera, the electric telescopic rod, and the transmission wheel via signals.

[0013] Furthermore, it also includes multiple magnetic plates, which are spaced apart on the top of the road surface and are used to magnetically connect with the guardrail connecting rod.

[0014] Furthermore, the self-moving guardrail includes multiple guardrail connecting rods and multiple guardrail bodies, and each of the guardrail connecting rods is equipped with the moving mechanism.

[0015] This invention can bring at least the following beneficial effects: The self-moving guardrail provided by the present invention includes: a guardrail connecting rod and a guardrail body, both of which are disposed on the road surface. The guardrail connecting rod is connected to both sides of the guardrail body. A through groove is formed inside the guardrail connecting rod, and a storage groove is formed on the side of the guardrail connecting rod. The storage groove is connected to the through groove, and the through groove is connected to the bottom of the guardrail connecting rod. A moving mechanism is disposed in the through groove.

When tidal movement is required, the drive assembly is activated, causing the transmission assembly to extend out of the through slot. Once at the designated position, the transmission assembly begins to move the guardrail connecting rod, achieving tidal movement of the self-moving guardrail. Simultaneously, the support assembly extends into its storage slot under the action of the transmission assembly, providing auxiliary support to the guardrail connecting rod from the side, preventing it from tipping over during movement and minimizing the impact on traffic caused by the guardrail connecting rod and the guardrail body tipping over, thus improving the device's efficiency. After the tidal movement is complete, the drive assembly is activated again, causing the transmission assembly to retract into the through slot, and the support assembly, under the action of the transmission assembly, retracts into its storage slot, completing the reset.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features described herein can be combined with each other. Figure 1 This is an overall schematic diagram of the self-moving guardrail provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the moving mechanism provided in an embodiment of the present invention; Figure 3 for Figure 2 A magnified view of a section at point A in the middle; Figure 4 for Figure 2 A magnified view of a section at point B.

[0027] Example 1 Existing self-moving guardrails designed for tidal changes typically move automatically to a designated location during operation. However, due to the large area of ​​the guardrails and the fact that the power source is located on the connecting poles on both sides, strong winds and other factors can cause them to tip over. If the guardrails tip over during tidal changes, not only will they be unable to reposition themselves smoothly, but they will also impact the road surface, creating roadblocks and disrupting traffic, severely impacting traffic efficiency.

[0028] In view of this, this embodiment of the invention provides a self-moving guardrail, including: a guardrail connecting rod 2 and a guardrail body 3, both the guardrail connecting rod 2 and the guardrail body 3 are disposed on the road surface 1, the guardrail connecting rod 2 is connected to both sides of the guardrail body 3; a through groove 4 is formed inside the guardrail connecting rod 2, and a storage groove 7 is formed on the side of the guardrail connecting rod 2, the storage groove 7 is connected to the through groove 4, the through groove 4 is connected to the bottom of the guardrail connecting rod 2, a moving mechanism is disposed in the through groove 4, the moving mechanism includes a driving component, a transmission component and a support component, the driving component is drivenly connected to the transmission component, the transmission component is drivenly connected to the support component, the transmission component can extend or retract into the through groove 4 under the action of the driving component, and the support component can extend or retract into the storage groove 7 under the action of the transmission component.

[0029] The entire moving mechanism is housed within the through slot 4. When not in use for tidal movement, it maintains the original structure of the guardrail connecting rod 2, ensuring the normal operation of the device's original functions. When tidal movement is required, the drive assembly is activated, causing the transmission assembly to extend out of the through slot 4. Once at the designated position, the transmission assembly begins to move the guardrail connecting rod 2, achieving tidal movement of the self-moving guardrail. Simultaneously, the support assembly extends into the storage slot 7 under the action of the transmission assembly, providing auxiliary support to the guardrail connecting rod 2 from the side. This prevents the guardrail connecting rod 2 from tipping over during movement, reducing the impact on traffic caused by the guardrail connecting rod 2 and the guardrail body 3 tipping over, and improving the device's working efficiency. After the tidal movement is complete, the drive assembly is activated again, causing the transmission assembly to retract into the through slot 4. The support assembly, under the action of the transmission assembly, retracts into the storage slot 7, completing the reset.

[0030] In an optional embodiment, the drive assembly includes an electric telescopic rod 5 and a control unit. The top end of the electric telescopic rod 5 is fixedly connected to the inner top wall of the guardrail connecting rod 2. The telescopic end of the electric telescopic rod 5 is connected to the transmission assembly. The control unit is signal-connected to the electric telescopic rod 5.

[0031] Please see Figure 2 The electric telescopic rod 5 is installed in the through groove 4. The electric telescopic rod 5 can extend and retract in the vertical direction, so that the transmission component can extend or retract into the through groove 4, and the support component can extend or retract into the storage groove 7.

[0032] In an optional embodiment, the transmission assembly includes a first transmission part and a second transmission part. The first transmission part includes a transmission wheel 6, a connecting block 8, and a first half gear 9. The top of the transmission wheel 6 is fixedly connected to the telescopic end of the electric telescopic rod 5. The transmission wheel 6 can extend or retract from the through groove 4 under the action of the electric telescopic rod 5. The telescopic end of the electric telescopic rod 5 passes through the connecting block 8 and is fixedly connected to the connecting block 8. The first half gear 9 is fixedly disposed on the side of the connecting block 8. The second transmission part is connected to the first half gear 9 in a transmission manner.

[0033] Please see Figure 2The first transmission unit realizes the self-moving function of the self-moving guardrail. The control unit starts the electric telescopic rod 5, which drives the transmission wheel 6 to extend out of the through slot 4, so that the transmission wheel 6 extends out of the bottom of the guardrail connecting rod 2. Start the transmission wheel 6, which drives the guardrail connecting rod 2 and the guardrail body 3 to move. The transmission wheel 6 is prior art known to those skilled in the art, so it will not be described in detail in this embodiment. When the telescopic end of the electric telescopic rod 5 starts to move, because the connecting block 8 is fixedly connected to the telescopic end of the electric telescopic rod 5, the connecting block 8 will move downward. At this time, the first half gear 9 on the connecting block 8 moves downward synchronously, thereby driving the second transmission unit to move, so that the support component extends out of the storage slot 7.

[0034] In an optional embodiment, the second transmission unit includes a second half gear 10, and the support assembly includes a support rod 11 and a rotating wheel 12. The second half gear 10 is hinged to the storage groove 7 and meshes with the first half gear 9. One end of the support rod 11 is fixedly connected to the side of the second half gear 10, and the other end is fixedly connected to the rotating wheel 12. The support rod 11 and the rotating wheel 12 can extend into or retract into the storage groove 7 under the action of the second half gear 10.

[0035] Please see Figure 2 When the first half gear 9 moves downward, since the first half gear 9 and the second half gear 10 are in a meshing state, and the second half gear 10 is hinged to the receiving groove 7, the second half gear 10 will start to rotate, and the support rod 11 on the other side of the second half gear 10 will change position, extending out of the receiving groove 7 from the guardrail connecting rod 2. The support rod 11 includes a first rod segment and a second rod segment connected in an L-shape. The first rod segment is fixedly connected to the side of the second half gear 10, and the second rod segment is fixedly connected to the rotating wheel 12. When the angle between the first rod segment and the guardrail connecting rod 2 shifts, the second rod segment extends synchronously and gets closer to the road surface 1. After the transmission wheel 6 extends to the designated position, the position of the rotating wheel 12 also moves to both sides of the guardrail connecting rod 2, and the distance between the rotating wheel 12 and the road surface 1 is smaller. See [link to relevant documentation]. Figure 3 If tipping or other issues occur, the rotating wheel 12 will support the guardrail connecting rod 2. After the rotating wheel 12 contacts the road surface 1, it will also begin to rotate under the movement of the transmission wheel 6, without affecting the movement of the guardrail connecting rod 2, thus improving the working efficiency of the device. After the guardrail connecting rod 2 moves to the designated position, the electric telescopic rod 5 is activated again to drive the transmission wheel 6 into the through groove 4 inside the guardrail connecting rod 2. At the same time, the connecting block 8 and the first half-gear 9 will also move upwards, causing the second half-gear 10 to rotate. The support rod 11 and the rotating wheel 12 are then stored in the receiving groove 7, without affecting the appearance of the guardrail connecting rod 2, making its shape more aesthetically pleasing. See [link to relevant documentation]. Figure 4 .

[0036] In an optional embodiment, a support column 13 is connected between the first rod segment and the second rod segment, and the support column 13, the first rod segment, and the second rod segment form a triangular structure.

[0037] Please see Figure 2 The support column 13 can support the support rod 11, and the triangular structure formed by the support column 13 and the support rod 11 is more stable. When the roller 12 on the support rod 11 needs to bear the weight of the guardrail connecting rod 2 and the guardrail body 3, the support rod 11 will be more stable due to the setting of the support column 13.

[0038] In an optional embodiment, the self-moving guardrail further includes a support frame 15 fixedly connected to the road surface 1, and the control unit is disposed on the support frame 15.

[0039] Please see details. Figure 1 The control unit includes a camera 16 and a sensor 17. The camera 16 is fixedly installed on the top of the support frame 15, and the sensor 17 is fixedly installed on the side of the support frame 15. The sensor 17 is connected to the camera 16, the electric telescopic rod 5 and the transmission wheel 6 respectively.

[0040] During tidal changes, camera 16 monitors the tidal changes and transmits the signal to sensor 17. Sensor 17 then controls the drive wheel 6 and the electric telescopic rod 5 via the signal, causing the guardrail connecting rod 2 and the guardrail body 3 to move and adjust their positions. The sensor 17 can be of model LPED-1500M18NS4D, and since sensor 17 is prior art known to those skilled in the art, it will not be described in detail in this embodiment.

[0041] In an optional embodiment, the self-moving guardrail further includes multiple magnetic plates 14, which are spaced apart on the top of the road surface 1. The magnetic plates 14 are used to magnetically connect with the guardrail connecting rod 2.

[0042] Please see Figure 1 After the guardrail connecting rod 2 is moved to the designated position, the magnetic suction plate 14 installed on the road surface 1 will attract the guardrail connecting rod 2 to the same horizontal plane to ensure that the guardrail connecting rod 2 reaches the designated position.

[0043] The movement of the guardrail connecting rod 2 is controlled by camera 16 and sensor 17, and uniformity is maintained after it moves to the designated position, which improves the working efficiency of the device, further reduces manual intervention, and improves the automation level of the device.

[0044] It should also be noted that the self-moving guardrail includes multiple guardrail connecting rods 2 and multiple guardrail bodies 3, and each of the guardrail connecting rods 2 is equipped with the moving mechanism.

[0045] The following describes the working process of the self-moving guardrail in this embodiment: Camera 16 detects changes in the tide and transmits the signal to sensor 17. Sensor 17 then activates the electric telescopic rod 5 via the signal control. The electric telescopic rod 5 drives the transmission wheel 6 downwards, extending it beyond the bottom of the guardrail connecting rod 2. Simultaneously, the connecting block 8 and the first half-gear 9 move downwards in sync, and the second half-gear 10 begins to rotate, causing the support rod 11 and the rotating wheel 12 to extend beyond the guardrail connecting rod 2. When the transmission wheel 6 extends to the designated position, the rotating wheel 12 is also positioned on both sides of the guardrail connecting rod 2, with only a small gap between it and the road surface 1. At this point, sensor 17 activates the transmission wheel 6 via the signal control, causing the guardrail connecting rod 2 and the guardrail body 3 to begin moving. If tilting or other issues occur during movement, the rotating wheel 12 will support the guardrail connecting rod 2. Furthermore, as the transmission wheel 6 continues to move, the rotating wheel 12 will contact the road surface 1 and begin to rotate, without affecting the movement of the guardrail connecting rod 2. After the guardrail connecting rod 2 moves to the designated position, the sensor 17 restarts the electric telescopic rod 5 to drive the transmission wheel 6 into the through groove 4 inside the guardrail connecting rod 2. At the same time, the connecting block 8 and the first half gear 9 will also move upward, causing the second half gear 10 to rotate. The support rod 11 and the rotating wheel 12 are then taken into the storage groove 7, completing one tidal movement.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
