[0002] Guardrails are devices that protect personal safety and equipment facilities, and are mainly used in residential areas, highways, commercial areas, public places, etc. Among them, the guardrails installed on the highway are the separation boundary between the highway and the external environment and the last barrier to protect vehicles. They play a vital role in ensuring the safety of vehicle driving. Therefore, the guardrails on the highway must play a sufficiently effective safety and anti-collision function, as well as a warning function. For example, the prior art (Announcement No. CN219951772U) discloses an anti-collision guardrail designed for municipal roads and bridges, which has the following effects: (1) When the pressure value exceeds the internal setting value of the pressure sensor, the pressure sensor can send an electrical signal to the alarm light, which can promptly remind the rear driver through the light when a collision occurs at night; (2) The solar panel converts solar energy into electrical energy to supply the pressure sensor and the alarm light for use.
[0003] Based on the prior art, it is found that since the position of the vehicle collision guardrail is uncertain, and the pressure sensor is usually point-to-point after being set, its triggering range is small. Therefore, in actual use, there will still be situations where the pressure sensor fails to work due to the collision position. In order to change this situation, a large number of pressure sensors are deployed, which will lead to an increase in equipment costs. Therefore, the utility model proposes a collision-proof guardrail for municipal roads and bridges to solve the problems existing in the prior art. Utility Model Content

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.
[0023] according to Figure 1-Figure 6 As described above, this embodiment proposes an anti-collision guardrail for a municipal road bridge, including a mounting frame 1, the cross-section of the mounting frame 1 is rectangular, a convex strip 18 is installed on the mounting frame 1, and a notch 19 is provided on the side of the mounting frame 1 away from the convex strip 18, and the notch 19 matches the convex strip 18, such as Figure 1 and Figure 4 As shown, the convex strip 18 and the recess 19 are respectively located on the left and right sides of the mounting frame 1, wherein the convex strip 18 itself can safely enter the recess 19. The purpose is that when two sets of mounting frames 1 are connected, one set of recesses 18 enters another set of recesses 19 for positioning, and then after the connection, they are fixed by bolts, so as to facilitate the connection between multiple sets of mounting frames 1.
[0024] An outer shell 2 is installed at the upper end of the mounting frame 1. Specifically, a PLC controller 9 is installed on the inner side of the outer shell 2, and an alarm flashing light 10 is installed on the outer shell 2, and the alarm flashing light 10 and the pressure sensor 8 are both electrically connected to the PLC controller 9. When the pressure sensor 8 is subjected to pressure, after the pressure value exceeds the internal set value of the pressure sensor 8, it sends a signal to the PLC controller 9, and the PLC controller 9 controls the alarm flashing light 10 to flash, which serves as a warning. In actual applications, dangerous accidents may occur in a night environment, and the alarm flashing light 10 on a single mounting frame 1 may be blocked by vehicles, etc., resulting in a reduction in its warning effect. Therefore, after multiple mounting frames 1 are installed, their corresponding PLC controllers 9 are connected. Therefore, when the alarm flashing light 10 corresponding to a group of mounting frames 1 starts to work, the alarm flashing lights 10 corresponding to the surrounding mounting frames 1 also start to work, thereby expanding the warning range and better warning the rear or surrounding drivers and vehicles.
[0025] The inner side of the mounting frame 1 is provided with an anti-collision tube 3, and the anti-collision tube 3 is evenly provided with a plurality of groups. In this embodiment, the anti-collision tube 3 is provided with three groups, such as Figure 3 As shown, the anti-collision cylinder 3 includes a main shaft 11, which is connected to the slider 5 through a bearing, and a rubber buffer cylinder 12 is sleeved on the outer side of the main shaft 11, and a first buffer cavity 13 and a second buffer cavity 14 are provided on the rubber buffer cylinder 12. The first buffer cavity 13 and the second buffer cavity 14 are both provided with a plurality of groups. Specifically, the first buffer cavity 13 is distributed on the outer part of the rubber buffer cylinder 12, and six groups are evenly arranged, while the second buffer cavity 14 is distributed on the inner part of the rubber buffer cylinder 12, and four groups are evenly arranged. Further, the inner side of the first buffer cavity 13 is provided with A buffer air bag 20 is provided, and the buffer air bag 20 is connected to the rubber buffer tube 12. A buffer layer 21 is filled in the second buffer cavity 14, and the buffer layer 21 is connected to the rubber buffer tube 12. Therefore, when the anti-collision tube 3 is impacted, a multi-path buffering effect is provided through the elasticity of the rubber buffer tube 12 itself, and the cooperation of the buffer air bag 20 and the buffer layer 21. At the same time, the anti-collision tube 3 has a rotatable effect, and under the action of the slider 5, the slide rod 6 and the buffer spring 7, they cooperate with each other, the buffering effect is good, and the damage caused by the vehicle collision is reduced.
[0026] Furthermore, mounting grooves 4 are provided on the mounting frame 1 on both the upper and lower sides of the anti-collision cylinder 3. In the present embodiment, two groups of mounting grooves 4 are provided for each group of anti-collision cylinders 3, which are distributed on the upper and lower sides of the mounting frame 1. Slide blocks 5 are provided on the inner sides of the corresponding mounting grooves 4, and slide bars 6 are provided on the inner sides of the slide blocks 5. There are multiple groups of slide bars 6. In the present embodiment, two groups of slide bars 6 are symmetrically provided. Both ends of the slide bars 6 pass through the slide blocks 5 and are connected to the mounting frame 1. As a result, the slide bars 5 can only move along the direction of the slide bars 6 in the mounting grooves 4. At the same time, buffer springs 7 are sleeved on the slide bars 6. The buffer springs 7 are provided in several groups. Specifically, four groups of buffer springs 7 are provided for each group of slide bars 6, which are distributed as shown in the following figure. Figure 2 As shown, correspondingly, two groups of symmetrically arranged pressure sensors 8 are installed on the inner side of the upper mounting groove 4, as shown in FIG. Figure 2 As shown, the two groups of pressure sensors 8 are symmetrically arranged with the slider 5. When the anti-collision cylinder 3 is subjected to force, it will drive the slider 5 to move on the slide rod 6. When it touches any group of pressure sensors 8, pressure is generated on the pressure sensor 8, and then the pressure sensor 8 sends a corresponding signal to the subsequent PLC controller 9. Setting the pressure sensor 8 on the upper part of the mounting frame 1 can effectively avoid rain erosion and ensure the operating stability of the equipment. At the same time, each group of anti-collision cylinders 3 is correspondingly provided with a pressure sensor 8, and the triggering range is wide.
[0027] Threaded holes 15 are provided on both sides of the outer shell 2. In this embodiment, an openable cover is provided on the upper end of the outer shell 2. Figure 4 As shown, a plugging member 16 is installed on one side (left side) of the threaded hole 15, and the plugging member 16 is connected to the outer shell 2 through a thread, and a wire barrel 17 is installed on the other side (right side) of the threaded hole 15, and the wire barrel 17 is connected to the outer shell 2 through a thread. Specifically, a connecting ring 22 is installed at one end of the wire barrel 17, and the diameter of the connecting ring 22 is smaller than the diameter of the threaded hole 15. Figure 6 As shown, after the two groups of mounting frames 1 are connected, the blocking piece 16 on one group (right side) of the outer shell 2 is removed, and then a hand-held tool is used to rotate the connecting ring 22 on the other group (left side) of the outer shell 2, thereby driving the wire barrel 17 to rotate, so that one end (right end) of the wire barrel 17 enters the (left side) threaded hole 15 of the right outer shell 2 and is connected through threads. Therefore, under the action of the wire barrel 17, it is convenient for the cables between the two groups of outer shells 2 to pass through, and it can also play a protective effect to prevent the connected cables from being exposed to the external environment.
[0028] In this embodiment, a reflective strip 23 is further provided on the outer side of the anti-collision tube 3 .
