[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0018] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0019] Embodiment, as Figures 1 to 5As shown in the figure, an anti-collision device for highway guardrail plates includes a vertical frame 1. On the outer side of the vertical frame 1, there is a guardrail plate 2 designed in a wavy shape. The establishment of the above-mentioned equipment components is all existing mature and commonly used technical means, and the details will not be elaborated here; further, a support plate 3 is arranged between the two vertical frames 1. On one side of the support plate 3, there is a buffer plate 4 designed in a Z shape. Two buffer plates 4 form a group and are designed in an isosceles trapezoid shape. Both sides of the buffer plate 4 are respectively connected to the support plate 3 and the guardrail plate 2 by bolts. In this way, the installed buffer plate 4 has good support and buffering effects, relatively improving the anti-collision performance of the guardrail plate 2; further, on the outer side of the guardrail plate 2 corresponding to the buffer plate 4, there is a buffer cylinder 5, one side of which is installed on the guardrail plate 2 corresponding to the corner of the buffer plate 4, reducing the opening of process holes and ensuring the use strength of the guardrail plate 2. At the same time, the buffer cylinder 5 can relieve the force to a certain extent when an impact occurs, improving the anti-collision performance; further: on the support plate 3 on one side of the buffer plate 4, there is a buffer anti-collision mechanism 6. The buffer anti-collision mechanism 6 includes an installation frame 61 designed in an obtuse angle shape and connected to the support plate 3. On one side of the installation frame 61, there is a frame body 62. Above the frame body 62, there is a limit rod 63, which penetrates through the installation frame 61. Inside both sides of the frame body 62, there are moving rods 65 designed in a T shape, and the other end of the moving rod 65 passes through the sleeve and penetrates to the outside of the installation frame 61. An anti-vibration spring 64 is sleeved on the outer circumference of the moving rod 65. The anti-vibration spring 64 is placed between the frame body 62 and the outer circle of the moving rod 65, providing convenient conditions for the moving rod 65 to move and adjust relative to the sleeve. In addition, a buffer spring (not shown in the figure) can also be sleeved on the moving rod 65 between the installation frame 61 and the frame body 62, so that the buffer anti-collision mechanism 6 has a secondary buffer anti-collision performance, effectively improving the use functionality of the device equipment. An installation hole 651 is opened inside the outer end of the moving rod 65. Specifically described as: the installation frame 61 is connected to the support plate 3. The establishment of the limit rod 63 can connect the installation frame 61 and the frame body 62 to ensure the stability of the equipment components formed. At the same time, one end of the limit rod 63 is fixedly connected to the frame body 62, and the other end can move relative to the installation frame 61, playing a role in limiting the moving direction inside the frame body 62. When the guardrail plate 2 is impacted, the moving rod 65 will move relative to the sleeve, and its rear end passes through the support plate 3 and compresses the buffer spring. This process realizes a primary buffer. When the frame body 62 moves to a position close to the installation frame 61, if the impact still exists, the moving rod 65 will continue to move and compress the anti-vibration spring 64, realizing a secondary buffer anti-collision, effectively improving the buffer anti-collision performance of the guardrail plate 2, reducing the danger, improving the use functionality of the device equipment, and meeting the use requirements;
[0020] During the above process: Through the buffer plate 4 and the buffer cylinder 5 which are used in cooperation with each other, the force generated by the impact can be relieved, and the buffer plate 4 can provide good buffering for the buffer cylinder 5, thereby improving the anti-collision performance of the guardrail plate 2 to a certain extent. By using the established buffer anti-collision mechanism 6, when an impact occurs, the moving rod 65 can move relative to the sleeve and cooperate with the shock-absorbing spring 64 to provide good buffering effect for the guardrail plate 2, ensuring the anti-collision performance and improving the functional use of the device and equipment to meet the use requirements. This device is reasonably designed, simple in structure, convenient to process, can improve the anti-collision and buffering performance of the guardrail plate 2, reduce the possibility of damage, and further improve the safety performance of the guardrail plate 2 to a certain extent, ensuring safety and effectively meeting the use requirements.
[0021] To ensure that the buffer cylinder 5 has good buffering performance, the buffer cylinder 5 includes a mounting plate 51. On one side of the mounting plate 51, there is a support plate 52 designed in an obtuse angle shape. At the end of the support plate 52, there is a rotating rod 53. Outside the rotating rod 53, there is a cylinder body 54 which is designed in a frustum of a cone shape. Specifically described as: The support plate 52 is fixedly connected to the mounting plate 51 to ensure the integrity of the components of the equipment. When installing, the mounting plate 51 of the buffer cylinder 5 is correspondingly installed at the connection of the buffer plate 4 and the guardrail plate 2, which improves the rationality of the established device and equipment to a certain extent, especially reducing the possibility of opening holes on the guardrail plate 2 and increasing the practicality. For the establishment of the buffer cylinder 5, it can pre-relieve the force during the impact process. Considering that there is a buffer plate 4 at the installation position of the buffer cylinder 5, the two cooperate with each other, effectively improving the anti-collision performance of the guardrail plate 2 and meeting the use requirements.
[0022] To ensure the stable connection of the support plate 3, a limiting frame 7 is provided on the outside of the vertical frame 1. The two sides of the support plate 3 are designed in an L shape and are in contact with the limiting frame 7. Among them, the limiting frame 7 is designed in a hollow shape and is fixedly connected to the vertical frame 1. There are also process holes inside it. When installing, the L-shaped part of the support plate 3 is in contact with the corner of the limiting frame 7, and then it is connected with bolts to ensure the connection stability between the devices.
[0023] To further improve the installation stability of the guardrail plate 2, a support frame 8 designed in a U shape is provided on the outside of the limiting frame 7. One side of the support frame 8 is designed in a concave shape and is sleeved on the limiting frame 7. Among them, the two sides of the support frame 8 are designed in a streamline shape, which can improve its anti-deformation ability to a certain extent, thereby improving the anti-collision performance of the guardrail plate 2. Further, the intersection of the sides is further connected to the limiting frame 7 with bolts, and the end of the support frame 8 is provided with an extension plate on one side and is in contact with the inner side of the guardrail plate 2, which is also connected with bolts, fully ensuring the integrity of the device components and improving the connection stability.
