[0002] As a major channel of modern transportation, the safe and smooth operation of highways is of great significance to socio-economic development and public travel. In actual operation, highways are often affected by factors such as ice and snow, traffic accidents, and road maintenance work, necessitating temporary closures or speed limits on certain sections. Existing closure methods typically rely on manually placing traffic cones and warning signs or using towed simple barriers. These methods have the following shortcomings: First, manual deployment is inefficient, especially on highways where it poses significant safety hazards. Second, traditional barriers have limited warning effects and cannot create a clear closed area in a short time, which can lead to rear-end collisions due to vehicles failing to slow down in time. Third, some vehicle-mounted warning devices are cumbersome to operate and cannot meet the needs of rapid, safe, and efficient operations in emergency scenarios.
[0003] Therefore, there is an urgent need to develop a vehicle-mounted automated highway rapid closure device that can quickly deploy from a vehicle to form a stable warning isolation zone, thereby improving the safety of emergency operations and the efficiency of road control.

Therefore, they should not be construed as limitations on this utility model. Example 1
[0018] like Figures 1 to 3 As shown, a vehicle-mounted automated highway rapid closure device includes: a mounting frame 1 mounted on a vehicle, a support plate 8 located at the center of the mounting frame 1, two multi-stage telescopic frames 3 located on both sides of the support plate 8, two winding shafts 7 rotatably connected to the support plate 8, two gears 9 located at the top of the two winding shafts 7, a servo motor 11 whose output shaft is connected to one of the gears 9 and fixedly connected to the inner wall of the mounting frame 1, and two pull ropes 6. Two gears 9 mesh with each other; two pull ropes 6 connect two take-up shafts 7 to two multi-stage telescopic frames 3 respectively. One end of each pull rope 6 is fixedly connected to the take-up shaft 7, and the other end is connected to the end of the corresponding multi-stage telescopic frame 3.
[0019] like Figure 3 and Figure 4 As shown, specifically, in this embodiment, the mounting bracket 1 is fixedly installed at the rear of the vehicle. The mounting bracket 1 is a rectangular frame with open ends. The support plate 8 is a rectangular horizontal plate. The two take-up shafts 7 are axially perpendicular to the support plate 8, and a gap is left between the two take-up shafts 7. One end of each pull rope 6 is fixedly connected to the take-up shaft 7, and the other end is connected to the end of the corresponding multi-stage telescopic frame 3. The two pull ropes 6 connect the two multi-stage telescopic frames 3 to the corresponding take-up shafts 7 respectively. In this embodiment, one take-up shaft 7 and one multi-stage telescopic frame 3 are connected by two pull ropes 6. The tops of both take-up shafts 7 are connected by... The shaft is connected to the gear 9, and the servo motor 11 is fixed between the two multi-stage telescopic frames 3. The output shaft of the servo motor 11 is connected to the gear 9. When the multi-stage telescopic frame 3 needs to be retracted, the output shaft of the servo motor 11 drives the winding shaft 7 to rotate through the drive gear 9. The rotation of the winding shaft 7 winds the pull rope 6 onto the winding shaft 7, pulling the multi-stage telescopic frame 3 back. When the multi-stage telescopic frame 3 needs to be unfolded, the rotation of the winding shaft 7 drives the pull rope 6 to lengthen, thereby slackening the pull rope 6. At this time, the multi-stage telescopic frame 3 can be pulled to extend, making road closure more convenient.
[0020] Preferably, in this embodiment, each level of the multi-level telescopic frame 3 is fixedly connected to an installation plate 5, and a warning light plate is fixedly connected to the front of the installation plate 5.
[0021] Preferably, in this embodiment, the upper end of the mounting bracket 1 is provided with a warning sign 10 and a PLC controller 2; there are two sets of warning signs 10, which are respectively located on both sides of the PLC controller 2. The output end of the PLC controller 2 is electrically connected to the servo motor 11. It should be understood that the servo motor 11, the warning sign 10 and the PLC controller 2 are also electrically connected to the power supply. Example 2
[0022] Based on Example 1, such as Figure 3 and Figure 4 As shown, in this preferred embodiment, the multi-level telescopic frame 3 includes a fixed tube body, a first-level telescopic frame sleeved on the fixed tube body, a second-level telescopic frame sleeved on the first-level telescopic frame, a third-level telescopic frame sleeved on the second-level telescopic frame, and a fourth-level telescopic frame sleeved on the third-level telescopic frame; each level of telescopic frame has the same structure, which is a U-shaped frame, and adjacent frames are sleeved and connected. Each level of telescopic frame is provided with an elastic piece 4, and the two ends of the elastic piece 4 are respectively connected to the adjacent telescopic frame.
[0023] like Figure 3As shown in the figure, specifically in this embodiment, in the secondary telescopic frame and the tertiary telescopic frame, each U-shaped frame has a limiting block 16 at the front end of the two branches of the tube. The two branches of the U-shaped frame of the rear stage are inserted into the two branches of the U-shaped frame of the front stage. The two branches of the U-shaped frame of the rear stage can slide in the two branches of the U-shaped frame of the front stage. One end of the elastic sheet 4 is connected to the limiting block 16 at the end of the two branches of the U-shaped frame of the rear stage, and the other end is connected to the limiting block 16 at the end of the two branches of the U-shaped frame of the front stage. In this embodiment, when the multi-stage telescopic frame 3 needs to be retracted, the output shaft of the servo motor 11 drives the winding shaft 7 to rotate via the drive gear 9. The rotation of the winding shaft 7 winds the pull rope 6 around the winding shaft 7, pulling the multi-stage telescopic frame 3 back. When the multi-stage telescopic frame 3 needs to be unfolded, the rotation of the winding shaft 7 drives the pull rope 6 to lengthen, thereby slackening the pull rope 6. At this time, the multi-stage telescopic frame 3 extends under the support of the elastic sheet 4. The multi-stage telescopic frame 3 extends automatically, making road closure more convenient. Example 3
[0024] Based on Examples 1 and 2, such as Figures 3 to 5 As shown, in this preferred embodiment, both ends of the two take-up shafts 7 away from the servo motor 11 are provided with threaded rods 12; the thread directions of the two threaded rods 12 are opposite, and two movable plates 13 are respectively sleeved at the ends of the two threaded rods 12; guide rods parallel to the threaded rods 12 are provided on both sides of the threaded rods 12, one end of the guide rod is fixedly connected to the mounting frame 1, and the other end extends out of the movable plate 13; the opposite ends of the two movable plates 13 are fixedly connected to the limiting frame 14.
[0025] Preferably, in this embodiment, the limiting frame 14 is a rectangular shell with one end open. A spring 15 is fixedly installed inside the limiting frame 14, and the other end of the spring 15 is fixedly connected to a limiting block 16. It should be noted that by using the spring 15 to support the limiting block 16, even if the side wall of the multi-stage telescopic frame 3 is obstructed by the limiting block 16, the limiting block 16 can still be pushed to squeeze the spring 15 away from the multi-stage telescopic frame 3, so that the multi-stage telescopic frame 3 can be stored without restriction. Preferably, in this embodiment, the limiting block 16 is a trapezoidal block, and the limiting block 16 can slide along the limiting frame 14.
[0026] In this embodiment, the mounting bracket 1 is installed at the rear of the work vehicle. When the road closure device is needed for road closure, the PLC can control the servo motor 11 to start. The servo motor 11 drives two gears 9 to rotate, and the two gears 9 drive the winding shaft 7 below them to rotate. Figure 2To illustrate, the left take-up shaft 7 rotates counterclockwise, and the right take-up shaft 7 rotates clockwise, causing the pull rope 6 wound on it to lengthen, thus extending the compressed elastic sheet 4 inside the multi-stage telescopic frame 3. Simultaneously, the right take-up shaft 7 also drives the threaded rods 12 at the upper and lower ends to rotate, causing the threaded rods 12 to move the movable plates 13 under the guide rod's limit, and simultaneously moving both movable plates 13 away from the take-up shaft 7. This causes the movable plates 13 to lift the limiting frame 14, which in turn lifts the limiting block 16, preventing the limiting block 16 from obstructing the multi-stage telescopic frame 3. At this point, the elastic sheet 4 pushes each U-shaped frame of the multi-stage telescopic frame 3 to slide sequentially until... Figure 1 or Figure 2 As shown, the road closure device can be quickly activated and the road can be closed without leaving the vehicle.
[0027] When the road closure ends and storage is required, the servo motor 11 can be controlled to rotate again, causing the servo motor 11 to drive the gear 9 to rotate, and the left winding shaft 7 to rotate clockwise and the right winding shaft 7 to rotate counterclockwise. This causes the winding shaft 7 to wind up the pull rope 6, and the end of the multi-stage telescopic frame 3 connected to the end of the pull rope 6 to be pulled and moved, causing the multi-stage telescopic frame 3 to gradually contract from the end, and squeezing the elastic plates 4 inside each tube to contract, so that the multi-stage telescopic frame 3 is finally wound up as shown. Figure 4 At the position shown, the threaded rod 12 simultaneously drives the moving plate 13 to move, and the moving plate 13 drives the limiting frame 14 to descend, so that the limiting block 16 at the lower end of the limiting frame 14 is placed outside the end of the contracted multi-stage telescopic frame 3, preventing the multi-stage telescopic frame 3 from elongating.
[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
