Description

Technical Field

[0001] This utility model belongs to the field of road collapse early warning technology, and specifically relates to a road collapse early warning structure. Background Technology

[0002] In existing road construction, road surface collapse is a common safety hazard, especially in special sections such as bridges, tunnels, and high slopes. The stability of the roadbed is affected by a variety of factors, such as geological conditions, construction quality, and aging after long-term use. Once a road surface collapse occurs, it will not only pose a serious safety threat to passing vehicles and pedestrians, but may also lead to traffic interruption and affect the normal operation of the social economy.

[0003] Currently, early warning methods for road collapses are relatively limited. Traditional early warning methods mainly rely on manual inspections and periodic testing, which are inefficient and cannot monitor the dynamic changes of the roadbed in real time. In addition, while some simple mechanical early warning devices can provide warnings to a certain extent, their complex structures, poor reliability, and susceptibility to external interference in actual use can lead to false alarms or missed alarms.

[0004] Therefore, developing a device that can monitor the condition of the roadbed in real time and accurately, and issue early warning signals in a timely manner when a collapse occurs, is of great significance for ensuring road traffic safety and reducing accident losses. Utility Model Content

[0005] To address the problems of untimely road collapse early warning, complex devices, and poor reliability in existing technologies, this utility model provides a road collapse early warning structure that can monitor the roadbed condition in real time, issue clear reflective warning signals in a timely manner, and does not affect normal traffic, thus possessing high practicality and economy.

[0006] The solution adopted by this utility model to solve its technical problem is: a road collapse early warning structure, including a roadbed, a steel plate, and a warning plate. The steel plate is fixed to one side of the road surface at the roadbed connection point by bolts and is located on the outermost lane. A main groove is opened on the upper surface of the steel plate. One end of the warning plate in the oncoming direction is hinged in the main groove by a pin, and the other end is free to move. A pull rope is connected to the free end of the warning plate. The far end of the pull rope is fixed to the other side of the road surface at the roadbed connection point. Reflective warning information is affixed to the inner surface of the warning plate. The pull rope is used to pull the warning plate to flip it over. After the warning plate flips from horizontal to vertical, the reflective warning information faces the oncoming direction. Diagonal braces are provided on the outer surface of the warning plate.

[0007] Furthermore, the outer surface of the warning board has a groove, one end of the diagonal brace is hinged in the groove, and the other end is free to move. An elastic rope is connected to the pull rope near the diagonal brace, and the far end of the elastic rope is connected to the diagonal brace.

[0008] Furthermore, the diagonal brace consists of a main support rod and a movable support rod. The main support rod is connected to the warning plate, and the movable support rod is movably fitted onto the far end of the main support rod, and the movable support rod is connected to the main support rod through a top spring.

[0009] Furthermore, a magnet is embedded in the groove of the warning plate on the side near the movable support rod, and the far end of the movable support rod is made of iron. The magnet attracts and limits the diagonal support within the groove.

[0010] Furthermore, the main channel is hinged with inclined plate one and inclined plate two. The lower end of inclined plate one is hinged to a fixed position in the main channel by a pin. The lower end of inclined plate two is horizontally slidably fitted into a sliding groove on the side wall of the main channel. The upper ends of inclined plate one and inclined plate two are hinged together. The two ends of the pull rope are respectively connected to the upper end of the warning plate and the road surface at the connection point. Reflective warning information is affixed to the side of the inclined plate facing the direction of oncoming vehicles.

[0011] Furthermore, when the warning plate is in a horizontal state, both it and the steel plate are on the same horizontal plane, and a limiting pin plate is installed at the connection between the end of the warning plate and the steel plate near the oncoming vehicle direction by screws.

[0012] Furthermore, the two ends of the steel plate are sloped structures.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes a linkage design between a pull rope and a warning board. When a roadbed collapses, the pull rope is tightened, and the warning board can quickly flip to a vertical position, with the reflective warning information facing the direction of oncoming traffic. This promptly alerts passing vehicles and pedestrians that the road ahead may collapse, requiring them to take evasive action in advance. The design of the diagonal brace effectively supports the warning board, ensuring its stability in a vertical position and preventing it from swaying or accidentally flipping due to external factors, thereby effectively preventing traffic accidents. This utility model has a simple structural design, mainly composed of steel plates, warning plates, pull ropes, and diagonal braces. The components are connected by simple mechanical connections to achieve their functions, resulting in high reliability and low maintenance costs. Furthermore, by adjusting the installation position of the steel plates and the length of the pull ropes, it can adapt to different road widths and roadbed structures, making it suitable for various road environments such as highways, bridges, and tunnels. It is especially suitable for road sections with poor roadbed stability and has wide applicability. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-7 This utility model provides a technical solution for a road collapse early warning structure: Example

[0018] This utility model provides a road collapse early warning structure, the schematic diagram of which is attached. Figure 1 As shown, the early warning structure mainly includes a roadbed 1, a steel plate 2, and a warning plate 5. The steel plate 2 is fixed to one side of the road surface at the connection point of the roadbed 1 in different roads such as bridges and highways by bolts 3, and is located on the outermost lane to ensure effective monitoring of potential collapses at the roadbed 1 connection point. Taking highways and bridges as examples, since the probability of bridge collapse is higher than that of normal highways, the steel plate 2 is installed on the highway to monitor and warn of bridge collapses. The two ends of the steel plate 2 are designed as sloping structures. This structural design not only facilitates smooth vehicle passage and reduces bumps caused by the height difference between the steel plate 2 and the road surface, but also guides water flow to a certain extent, preventing water accumulation from eroding the connection point between the roadbed 1 and the steel plate 2.

[0019] like Figure 3As shown, a main groove 4 is provided on the upper surface of the steel plate 2. One end of the warning plate 5 in the direction of oncoming traffic is hinged to the main groove 4 by a pin, while the other end is in a free-moving state. Reflective warning information 6 is affixed to the inner surface of the warning plate 5. This reflective warning information 6 can clearly remind passing vehicles and pedestrians of danger at night or in low-light environments. A pull rope 7 is connected to the free-moving end of the warning plate 5. The far end of the pull rope 7 is connected and fixed to the road surface on the other side of the roadbed 1 connection. A traction block is embedded in the road surface, and the pull rope is connected to the traction block. For example, if the steel plate 2 is installed on a highway, the far end of the pull rope 7 is connected to the traction block embedded in the bridge road surface. When the bridge collapses, the settlement of the roadbed 1 will cause the rope 7 to be tightened, which in turn will cause the warning board 5 to flip. After the warning board 5 flips from a horizontal state to a vertical state, the reflective warning information 6 is facing the direction of oncoming traffic, which can promptly and clearly issue a warning signal to vehicles and pedestrians, reminding them that the road surface ahead may collapse and that they need to take evasive measures in advance, thereby effectively avoiding traffic accidents.

[0020] In addition, a diagonal brace 8 is provided on the warning board 5. The outer surface of the warning board 5 has a groove. One end of the diagonal brace 8 is hinged in the groove by a special pin with an angle limiting function. The diagonal brace 8 can rotate around the pin at an angle of 30° or 45°. The other end of the diagonal brace 8 is in a free-moving state. An elastic rope 9 is connected to the pull rope 7 near the diagonal brace 8. The far end of the elastic rope 9 is connected to the diagonal brace 8. The elastic rope 9 can pull the diagonal brace 8 to rotate simultaneously when the pull rope 7 pulls the warning board 5 to flip. When the roadbed 1 collapses and the pull rope 7 is tightened, the elastic rope 9 will also be stretched, thereby pulling the diagonal brace 8 to rotate together. When the warning board 5 is flipped to a vertical state, the diagonal brace 8 supports the rear of the warning board 5, providing a certain support force for the warning board 5, so that it can maintain a stable state in the vertical state, and prevent the warning board 5 from shaking or flipping at will due to external factors (such as wind, airflow generated by vehicle movement, etc.), thereby improving the stability and reliability of the warning structure.

[0021] The diagonal brace 8 consists of a main support rod 801 and a movable support rod 802. The main support rod 801 is hinged to the warning plate 5, and the movable support rod 802 is movably fitted onto the far end of the main support rod 801. The movable support rod 802 is connected to the main support rod 801 through a top spring 803. When the pull rope 7 pulls the warning plate 5 to flip, the diagonal brace 8 can push the movable support rod 802 to extend under the action of the top spring 803, increasing the length of the diagonal brace 8, so that the diagonal brace 8 can be smoothly supported behind the warning plate 5.

[0022] Furthermore, when the diagonal brace 8 and the warning plate 5 are in a horizontal state, they are on the same horizontal plane as the steel plate 2. This design ensures that under normal circumstances, the entire warning structure remains flat with the road surface, without affecting the normal driving of vehicles, and can also blend well into the road environment without affecting the overall aesthetics of the road. A limiting pin 14 is installed at the connection between the end of the warning plate 5 and the steel plate 2 near the oncoming traffic direction by screws. The limiting pin 14 is made of plastic. Under normal circumstances, the warning plate 5 is restrained in a horizontal state by the limiting pin 14 and will not flip over without reason. When the road surface collapses, under the action of tension, the warning plate 5 will overcome the restriction of the limiting pin 14 and rotate upright. The limiting pin 14 will break after one use, and a new pin can be replaced during subsequent maintenance.

[0023] In practical use, this utility model's road collapse early warning structure, under normal circumstances, has a warning plate 5 in a horizontal state, flat with the steel plate 2 and the road surface, allowing vehicles to pass normally without affecting vehicle traffic. When the bridge collapses, the settlement of the roadbed 1 causes the pull rope 7 to tighten. The tension of the pull rope 7 pulls the warning plate 5 to rotate around the pin, gradually turning the warning plate 5 from a horizontal state to a vertical state. During this process, the elastic rope 9 connected to the pull rope 7 is also stretched. The tension of the elastic rope 9 drives the diagonal brace 8 to rotate around its hinge point. At the same time, the top spring 803 inside the diagonal brace 8 pushes the movable support rod 802 to extend, increasing the length of the diagonal brace 8. The diagonal brace 8 supports the rear of the warning plate 5, ensuring that the warning plate 5 remains stable in a vertical state. When the warning plate 5 is rotated to a vertical state, the reflective warning information 6 faces the direction of oncoming traffic, clearly reminding passing vehicles and pedestrians that the road surface ahead may collapse and that they need to take avoidance measures in advance. With the above structure, this utility model can issue a timely and obvious early warning signal when the roadbed 1 collapses, reminding vehicles and pedestrians to pay attention to the danger and effectively avoiding traffic accidents. Example

[0024] Based on Example 1, such as Figure 4 As shown, a magnet 10 is embedded in the groove of the warning plate 5 near the movable support rod 802, and the distal end of the movable support rod 802 is made of iron. Under normal circumstances, the movable support rod 802 extends into the main support rod 801, and the entire diagonal support 8 is placed in the groove. Through the positioning and adsorption effect of the magnet 10, the diagonal support 8 is adsorbed and limited in the groove, so that the diagonal support 8 remains stable in the warning plate 5. This ensures that the diagonal support 8 will not loosen or shift due to external interference when the warning is not triggered, thereby improving the stability of the warning structure. When the pull rope 7 pulls the warning plate 5 to flip, the diagonal support 8 overcomes the adsorption force of the magnet 10 under the action of the elastic rope 9 and detaches from the groove, completing the flipping and extension action. Example

[0025] This embodiment provides a technical solution for flipping the warning board, which differs from Embodiment 1.

[0026] like Figure 6 and Figure 6 As shown, inclined plate 11 and inclined plate 22 are hinged at one end of the main groove 4 of steel plate 2. Here, inclined plate 11 serves as a warning plate 5. The lower end of inclined plate 11 is hinged to a specific position of the main groove 4 by a pin. The lower end of inclined plate 212 is horizontally slidably fitted into a sliding groove 13 opened on the side wall of the main groove 4 by a pin. The upper ends of inclined plate 11 and inclined plate 212 are hinged to the same top block. The two ends of the pull rope 7 are respectively connected to the inclined plate 212 and the road surface at the connection point. Reflective warning information 6 is affixed to the side of inclined plate 11 facing the oncoming vehicle direction. To improve the warning effect, reflective warning information can also be affixed to inclined plate 212. In addition, a limiting pin can be set at an appropriate position of inclined plate 1 or inclined plate 2 to prevent it from flipping over without cause.

[0027] When the road surface is not collapsed, both inclined plates 11 and 12 are horizontally positioned within the groove, not affecting normal vehicle passage. When the road surface collapses, the pull rope 7 pulls inclined plate 12 outwards, simultaneously rotating inclined plate 11 until the lower end of inclined plate 12 moves to the end of the groove and is blocked, thus causing inclined plates 11 and 12 to rotate as if... Figure 6 The state shown allows the inclined plate 11 and inclined plate 2 12 to cooperate with the groove to form a stable triangular structure, so that the inclined plate 11 and inclined plate 2 12 stand up and provide early warning through the reflective warning information 6 on the surface of the inclined plate 11.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
