Description

Technical Field

[0001] This utility model relates to the technical field of road closure equipment, specifically to a road closure device. Background Technology

[0002] In the field of road traffic management, when traffic accidents or other emergencies occur on roads or in tunnels, it is usually necessary to temporarily close the affected road section or tunnel entrance to prevent vehicles from continuing to pass and to avoid secondary accidents. Currently, most common road closure devices adopt a lifting barrier structure, using a motor or hydraulic drive to raise and lower the barrier to achieve the purpose of closing or opening the road. However, existing lifting barrier technologies have the following limitations:

[0003] 1. Limited length of the stop lever

[0004] Due to limitations in the support structure and drive mechanism of retractable barriers, their length is typically short, making them unsuitable for wide roads or multi-lane road closures. When the road width is large, a single barrier cannot completely cover the road cross-section, resulting in poor closure and posing safety hazards such as vehicles having to detour or illegally cross the road.

[0005] 2. Insufficient warning effect

[0006] When short barriers are used to close wide roads, multiple barriers often need to be installed in parallel. This not only increases equipment costs and deployment time, but may also reduce the warning effect due to excessive spacing, affecting drivers' ability to identify the closed area.

[0007] 3. Installation and stability issues

[0008] When a lifting barrier is deployed, it needs a stable support structure. If the barrier is too long, its wind resistance and mechanical stability will be significantly reduced, and it will be easily deformed or tilted by external forces, affecting the reliability of the closure.

[0009] Therefore, existing lifting-type road closure devices are insufficient to meet the closure requirements of wide roads or long-span tunnels. There is an urgent need for a road closure device that can adapt to wide roads, has a longer closure range, and has a stable structure to improve closure efficiency and safety. Utility Model Content

[0024] Furthermore, it also includes a control cabinet and a protective box, the drive mechanism is located inside the control cabinet, the control cabinet is provided with a cabinet door, and the protective box is installed outside the slewing bearing.

[0025] Furthermore, it also includes a light box, which is mounted on the rotating shaft and, in the interception state, is positioned facing the direction of travel.

[0026] Furthermore, it also includes a controller, limit switches, a sound system, an alarm, and a projection light, wherein the controller, the limit switches, and the sound system are all housed within the control cabinet;

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0040] Example 1

[0041] like Figures 1 to 5As shown, a road closure device according to the first aspect of the present invention includes a stop bar 1, a pull rope 2, a rotating shaft 3 and a drive device. The rotating shaft 3 is cylindrical and vertically arranged. The drive device is connected to the rotating shaft 3 for transmission and is used to drive the rotating shaft 3 to rotate.

[0042] The stop lever 1 is arranged in a direction perpendicular to the rotating shaft 3, and one end of the stop lever 1 is connected to the rotating shaft 3;

[0043] like Figure 1 As shown, the pull rope 2 is made of steel wire rope. One end of the pull rope 2 is connected to the rotating shaft 3, and the other end of the pull rope 2 is connected to the stop bar 1. The connection point between the rotating shaft 3 and the pull rope 2 is higher than the connection point between the rotating shaft 3 and the stop bar 1. The connection point between the pull rope 2 and the stop bar 1 is close to the end of the stop bar 1 that is away from the rotating shaft 3. The stop bar 1, the pull rope 2 and the rotating shaft 3 together form a right-angled triangle structure. The overall structure is stable and can extend the length of the stop bar 1 to more than 10 meters.

[0044] In this embodiment, it should be noted that the stop bar 1 can adopt a multi-segment structure. Specifically, the stop bar 1 includes multiple rods, which are arranged sequentially along a straight line. The two adjacent rods are detachably connected. By adopting a multi-segment structure, it is convenient for transportation and disassembly, and when a certain rod is damaged, it can be replaced individually.

[0045] The technical effects achieved in this embodiment are as follows: the entire device uses the rotating shaft 3 to drive the stop bar 1 to rotate horizontally for road closure and interception, and the pull rope 2 assists in pulling the stop bar 1. The overall structure is stable, which can significantly reduce the deflection deformation of the stop bar 1 caused by its own weight and wind load, allowing it to maintain stable operation even under ultra-long span conditions. This greatly extends the applicable length of the stop bar 1, breaking through the span limitations of traditional road closure devices. It is particularly suitable for wide roads, long-span tunnels, and other scenarios, meeting the requirements for high stability and high reliability in road closure. In addition, the structure is simple and easy to maintain, and can be widely used in traffic management, emergency road closures, and regional isolation, with high practical value and market prospects.

[0046] Example 2

[0047] like Figures 1 to 5 As shown in the figure, another road closure device provided in this embodiment has the same structure as that in embodiment 1. Only the different parts are described below.

[0048] In this embodiment, a mounting base 5 is also included, which is detachably connected to the rotating shaft 3, and one end of the stop rod 1 is detachably connected to the mounting base 5.

[0049] In this embodiment, it should be noted that, as Figures 2 to 5As shown, the mounting base 5 includes a fixed base 15 and a connecting pin 14. The fixed base 15 is provided with a mounting groove 19 along its length direction. The shape and size of the mounting groove 19 are adapted to the stop bar 1. Specifically, the stop bar 1 is a rectangular tube and the mounting groove 19 is a rectangular groove. The two sides of the width direction of the mounting groove 19 are respectively provided with locking blocks 18. The locking blocks 18 are used to lock the stop bar 1 in the mounting groove 19 to prevent the stop bar 1 from falling off.

[0050] One end of the stop bar 1 is engaged with the mounting groove 19. The connecting pin 14 passes through the fixed seat 15 and the stop bar 1 along the width direction of the mounting groove 19, and the connecting pin 14 is rotatably connected to the stop bar 1. In the interception state, the opening of the mounting groove 19 faces the same direction as the vehicle's travel direction. When the vehicle accidentally hits the stop bar 1 during the interception process, the stop bar 1 can be dislodged from the mounting groove 19 and rotate along the connecting pin 14, thereby preventing the stop bar 1 from being broken.

[0051] Furthermore, such as Figures 3 to 5 As shown, the mounting base 5 also includes a limiting seat 16 and a clamp 17. One end of the limiting seat 16 is connected to one end of the fixed base 15. The limiting seat 16 is arranged in a direction perpendicular to the fixed base 15.

[0052] The limiting seat 16 has a limiting groove 20, which communicates with the mounting groove 19. The shape and size of the limiting groove 20 are adapted to the stop bar 1. The limiting groove 20 is arranged in a direction perpendicular to the mounting groove 19, such as... Figure 3 As shown, one end of the stop lever 1 connected to the mounting base 5 extends to the outside of the fixed base 15. When a vehicle accidentally hits the stop lever 1 during the interception process, the stop lever 1 can rotate along the connecting pin 14 and can fall out of the mounting groove 19. When the end of the stop lever 1 rotates into the limiting groove 20, it is limited by the limiting groove 20 and thus stops rotating, which can prevent the stop lever 1 from rotating too much and touching the obstacle.

[0053] The clamp 17 is located on the back of the fixed seat 15. The clamp 17 and the fixed seat 15 are connected by bolts. The fixed seat 15 is fixed on the rotating shaft 3 by the clamp, which facilitates installation.

[0054] The technical effect achieved by this embodiment is that the entire mounting base 5 is equipped with an anti-collision structure and a limiting structure, which can effectively protect the stop bar 1 and prevent the stop bar 1 from being broken by impact.

[0055] Example 3

[0056] like Figures 1 to 5 As shown in the figure, another road closure device provided in this embodiment has the same structure as that in embodiment 1. Only the different parts are described below.

[0057] In this embodiment, the driving device includes a driving mechanism 11, a transmission shaft 13 and a rotary bearing 9. The transmission shaft 13 is coaxially arranged with the rotating shaft 3. The bottom end of the transmission shaft 13 is connected to the output shaft of the driving mechanism 11, and the top end of the transmission shaft 13 is connected to the rotary bearing 9.

[0058] The slewing bearing 9 is mounted on the mounting bracket 10. The bottom end of the rotating shaft 3 is connected to the slewing bearing 9. During operation, the rotating shaft 3 is driven to rotate by the slewing bearing 9, which can stably control the rotation of the rotating shaft 3.

[0059] In this embodiment, it should be noted that the drive mechanism 11 may be a motor, and also includes a flange 12. The output shaft of the drive mechanism 11 is connected to the transmission shaft 13 through the flange 12.

[0060] The technical effect achieved by this embodiment is that the entire drive device has a simple structure and can stably control the operation of the entire device.

[0061] Example 4

[0062] like Figures 1 to 5 As shown in the figure, another road closure device provided in this embodiment has the same structure as that in embodiment 1. Only the different parts are described below.

[0063] In this embodiment, a control cabinet 7 and a protective box 6 are also included. The drive mechanism 11 is installed inside the control cabinet 7. The control cabinet 7 is provided with a cabinet door 8. The protective box 6 is installed outside the rotary bearing 9 to provide protection.

[0064] In this embodiment, it should be noted that a light box 4 is also included. The light box 4 is mounted on the rotating shaft 3. In the interception state, the light box 4 is positioned facing the direction of travel. The light box 4 can be used to affix warning signs to remind and warn vehicles.

[0065] Furthermore, it also includes a controller, limit switches, a sound system, an alarm, and a projection light. The controller, limit switches, and sound system are all located in the control cabinet 7. The sound system is used to play warning voice messages, and the limit switches are used to identify whether the rotating shaft 3 has rotated the lever 1 to the designated position. During the rotation, the sound system continuously emits warning voice messages. When the lever 1 is rotated to the designated position, the controller controls the alarm and projection light to turn on.

[0066] The alarm is an audible and visual alarm, which is set on the top of the rotating shaft 3. The projection light is set on the rotating shaft 3 and is used to project warning signs on the ground.

[0067] The light box 4, drive mechanism 11, limit switch, sound, alarm and projection light are all electrically connected to the controller. The controller can be connected to a remote control module, which can remotely control the entire device.

[0068] The technical effect achieved by this embodiment is that the entire device has multiple sound and light warning functions, has a good warning effect, and the entire device can be remotely operated and controlled.

[0069] Example 5

[0070] This embodiment provides another road closure device, the structure of which includes all the contents of embodiment 4. Only the different parts are described below.

[0071] In this embodiment, a camera and a detection radar are also included. Both the camera and the detection radar are mounted on the control cabinet 7 and are electrically connected to the controller. The camera is positioned facing the direction of vehicle travel on the road and is used to capture and collect vehicle information on the road. When no vehicle is detected on the road, the camera can send a signal to the controller to automatically initiate an interception program and use the barrier 1 to intercept the road (suitable for temporary road closures, such as when a road or tunnel is temporarily closed). The radar detector is used to detect whether there are obstacles in the rotation area of ​​the barrier 1 after the road closure program is initiated. When an obstacle is detected in front of the barrier 1, the radar detector can send a signal to the controller to automatically stop the rotation of the barrier 1, thereby preventing a collision accident.

[0072] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0073] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
