Description

Technical Field

[0001] This utility model relates to the field of tidal lane guardrail technology, and in particular to a limiting device for tidal lane guardrail. Background Technology

[0002] Reversible lanes, as a flexible means of allocating road resources, effectively alleviate traffic congestion by adjusting lane direction according to changes in traffic flow at different times. Traditional reversible lane barriers mostly use simple clips or pins for limiting movement, which cannot guarantee that the barriers will move precisely to the corresponding positions during the reversible lane barrier movement process.

[0003] More importantly, the existing tidal flow lane guardrails require manual operation of the limit device to fix their position when they are moved, and the adjustment process is time-consuming (especially during peak hours), which affects the efficiency of road traffic. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a limiting device for a tidal lane guardrail.

[0005] The present invention adopts the following technical solution.

[0006] A limiting device for a tidal flow lane guardrail includes a mounting shell and a fixing plate, wherein the fixing plate is fixed to the top of the mounting shell. The device is characterized in that: a top plate and a supporting shell are provided on the inner side of the mounting shell, and a driving part is provided inside the mounting shell; a rotating rod passes through one end of the top plate, and both ends of the rotating rod are connected to the inner wall of the mounting shell; the supporting shell is fixed below the top plate, and a supporting plate is connected to one side of the supporting shell.

[0007] To improve the accuracy of the movement of the tidal lane guardrail, the drive unit includes a drive rod, a threaded rod, and a drive motor. The drive motor is located inside the mounting housing, and the threaded rod is connected to the output end of the drive motor. The drive rod is located inside the cavity formed by the mounting housing and the supporting housing. One end of the drive rod is rotatably connected to a moving plate, which wraps around the threaded rod and is threadedly connected to it.

[0008] Preferably, the end of the drive rod away from the moving plate is rotatably connected to a rotating component, and the rotating component is connected to the top plate.

[0009] Preferably, two limiting plates are provided on both sides of the threaded rod, and the two limiting plates are located on both sides of the moving plate and are in contact with the moving plate.

[0010] To extend the service life of the limit device of the tidal lane guardrail, a support rod is connected inside the mounting shell, and a rubber pad is connected to the top of the support rod.

[0011] To improve the safety of the limit device of the tidal lane guardrail, reflective strips are installed above the fixing plate.

[0012] Preferably, the surface of the top plate is provided with a number of raised strips.

[0013] To further extend the service life of the limit device of the tidal lane guardrail, the bottom surface of the mounting shell has drainage holes, and a drainage shell is connected below the mounting shell. The inner bottom surface of the drainage shell is inclined, and a drainage pipe is connected to one side of the drainage shell.

[0014] Beneficial effects: The limiting device of the tidal lane guardrail of this utility model can not only improve the accuracy of the movement of the tidal lane guardrail, but also improve the safety during use.

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0024] Combination Figures 1-6 As shown, a limiting device for a tidal lane guardrail includes a mounting shell 1 and a fixing plate 2. The fixing plate 2 is fixed to the top of the mounting shell 1. The device is characterized in that: a top plate 3 and a supporting shell 4 are provided on the inner side of the mounting shell 1, and a driving part is provided inside the mounting shell 1. A rotating rod 5 passes through one end of the top plate 3, and both ends of the rotating rod 5 are connected to the inner wall of the mounting shell 1. The supporting shell 4 is fixed below the top plate 3, and a supporting plate 6 is connected to one side of the supporting shell 4.

[0025] The drive unit includes a drive rod 7, a threaded rod 8, and a drive motor 9. The drive motor 9 is located inside the mounting housing 1. The threaded rod 8 is connected to the output end of the drive motor 9. The drive rod 7 is located inside the cavity formed by the mounting housing 1 and the supporting housing 4. One end of the drive rod 7 is rotatably connected to a movable plate 10. The movable plate 10 wraps around the threaded rod 8 and is threadedly connected to the threaded rod 8.

[0026] The drive rod 7 is rotatably connected to a rotating component 11 at the end away from the moving plate 10, and the rotating component 11 is connected to the top plate 3.

[0027] Two limiting plates 12 are respectively provided on both sides of the threaded rod 8. The two limiting plates 12 are located on both sides of the movable plate 10 and are in contact with the movable plate 10.

[0028] The mounting housing 1 has a support rod 13 inside, and a rubber pad 14 is connected to the top of the support rod 13.

[0029] A reflective strip 15 is provided above the fixing plate 2.

[0030] The surface of the top plate 3 is equipped with several raised strips 16.

[0031] The mounting shell 1 has a drainage hole 17 on its bottom surface, and a drainage shell 18 is connected to the bottom of the mounting shell 1. The inner bottom surface of the drainage shell 18 is inclined, and a drainage pipe 19 is connected to one side of the drainage shell 18.

[0032] In this embodiment, the limiting device of the tidal flow lane guardrail is installed with the mounting shell 1 and drainage shell 18 buried below the ground, the drainage pipe 19 connected to the external sewage pipe, and the fixing plate 2 located above the ground. Before the tidal flow lane guardrail adjusts its position, the drive motor 9 drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 drives the moving plate 10 to move along the axial direction of the threaded rod 8. When the moving plate 10 moves, it will drive one end of the drive rod 7 to move. With the assistance of the rotating part 11, the drive rod 7 gradually moves to be perpendicular to the threaded rod 8, and can lift the top plate 3, and drive the supporting shell 4 to move upward. When the tidal flow lane guardrail moves until its bottom contacts and supports the supporting plate 6, the position of the tidal flow lane guardrail is limited. At the same time, when the limiting device of the tidal flow lane guardrail is not working (i.e., when the top plate 3 is parallel to the mounting plate), the reflective strip 15 can remind drivers on the road to avoid the limiting device of the tidal flow lane guardrail, and when the tires of motor vehicles drive over the top plate 3, the raised strip 16 will vibrate with the tires to remind the driver.

[0033] During rainy weather, rainwater flowing into the mounting shell 1 will flow into the drainage shell 18 through the drainage hole 17, and the slope of the drainage shell 18 can collect the rainwater to the drainage pipe 19 and discharge it through the externally connected sewage pipe.

[0034] The limiting device of the tidal lane guardrail in this embodiment can not only improve the accuracy of the movement of the tidal lane guardrail, but also improve the safety during use. Compared with traditional limiting devices, the limiting device of the tidal lane guardrail has a longer service life. More importantly, it can improve road traffic efficiency by eliminating the need for manual operation to fix the position of the limiting device.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
