Description

Technical Field

[0001] The present application relates to the technical field of anti-collision guardrails, and more specifically, to an anti-collision guardrail for a municipal road bridge. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. With the rapid development of public transportation, bridges have been built in large numbers due to their characteristics of crossing rivers and shortening road mileage. A bridge guardrail refers to a guardrail installed on a bridge. Its purpose is to prevent pedestrians and out-of-control vehicles from going over the bridge. It has the function of preventing pedestrians and vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure.

[0003] During the use of bridges, if a vehicle has an accident on the bridge, if the guardrails on the bridge are not strong enough, the vehicle will fall into the river, causing great harm to society. The existing guardrails have relatively simple functions and their anti-collision performance is not very high.

[0004] In order to solve the above problems, the present application provides an anti-collision guardrail for a municipal road bridge. Utility Model Content

[0005] The anti-collision guardrail of a municipal road bridge provided in this application adopts the following technical solution:

[0009] Furthermore, the connection card and the insertion slot have the same shape, the first alignment hole and the second alignment hole overlap each other when spliced, and have the same diameter shape.

[0010] Furthermore, the anti-collision mechanism includes a sleeve, a surrounding high-strength buffer spring is provided in the sleeve, a main rod is penetrated in the sleeve, and the main rod passes through the surrounding high-strength buffer spring, an annular abutment ring is provided on the outer wall of the main rod, and the abutment ring is located in the sleeve, an annular buffer pad is provided on the outer wall of the end of the main rod away from the sleeve, and a buffer impact plate is provided on the end of the main rod away from the sleeve.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The design of the anti-collision mechanism has layered buffering and protection effects. The sleeve provides soft buffering support through the surrounding high-strength buffer spring. The main rod passes through the spring as a supporting structure and is equipped with an annular abutment ring on the outside to enhance the overall stability of the structure.

[0021] Example:

[0022] The present application embodiment discloses an anti-collision guardrail for a municipal road bridge, see Figure 1-Figure 3 , including a guardrail support column 1, wherein a uniformly distributed crossbeam mechanism 2 is penetrated through the guardrail support column 1, an anti-collision mechanism 6 is penetrated through the guardrail support column 1, a ground trapezoidal fixing ring 3 is provided on the outer wall at the bottom of the guardrail support column 1, a ground insertion cone 4 is provided at the bottom of the guardrail support column 1, and the ground insertion cone 4 is located below the ground trapezoidal fixing ring 3, and uniformly distributed ground teeth 5 are provided on the outer wall of the ground insertion cone 4, and uniformly distributed reserved holes 7 are penetrated through the guardrail support column 1, and the diameter of the reserved holes 7 is the same as that of the anti-collision mechanism 6, and the anti-collision mechanism 6 penetrates the reserved holes 7, and the top of the second step of the ground trapezoidal fixing ring 3 is observed to be provided with uniformly distributed fixing holes 8, the internal crossbeam mechanism 2 and the anti-collision mechanism 6 are arranged, as well as the ground trapezoidal fixing ring 3, the ground insertion cone and the ground teeth 4 at the bottom, all demonstrate the stability and safety of the system. The design of reserved holes 7 and fixing holes 8 also facilitates the expansion and fixation of the system. The uniform distribution of fixing holes 8 further enhances the reliability of the structure. Such guardrail support 1 design should be able to play an excellent role in actual use and provide effective protection and support functions.

[0023] The crossbeam mechanism 2 and the anti-collision mechanism 6 are perpendicular to each other, and the anti-collision mechanism 6 is located between the crossbeam mechanisms 2. The number of the crossbeam mechanisms 2 is three. The design of increasing the number of crossbeam mechanisms 2 to three and keeping the positions of the crossbeam mechanisms 2 perpendicular to each other and the anti-collision mechanism 6 still being located between the crossbeam mechanisms 2 will further enhance the stability and safety of the guardrail support column. By increasing the number of crossbeam mechanisms 2, the load can be effectively dispersed and the bearing capacity of the overall structure can be improved. At the same time, the vertical arrangement of the anti-collision mechanism 6 in the relative position is maintained, which helps to absorb and reduce the impact of the collision and improve the protective effect of the guardrail support column 1.

[0024] The crossbeam mechanism 2 includes a crossbeam 201, a connection card 202 is provided at one end of the crossbeam 201, and a symmetrical second alignment hole 205 is provided in the middle position of the protrusions at the upper and lower ends of the connection card 202, an insertion slot 203 is provided at the other end of the crossbeam 201 away from the connection card 202, and symmetrical first alignment holes 204 are provided at the upper and lower ends of the outer wall of the crossbeam 201 away from the connection card 202, and the design features of the crossbeam 201 and the connection card 202 can be effectively expanded and further reinforced by adding the insertion slot 203, the symmetrical first alignment hole 204 and the second alignment hole 205. Adding these structural elements can improve the connection stability and bearing capacity of the crossbeam mechanism 2, thereby enhancing the strength and durability of the overall structure. At the same time, the symmetrically arranged second alignment holes 205 and the first alignment holes 204 help to ensure the position accuracy and stability during assembly, making the crossbeam mechanism 2 safer and more reliable during use.

[0025] The connection card 202 and the insertion slot 203 have the same shape, and the first alignment hole 204 and the second alignment hole 205 overlap each other during splicing and have the same diameter shape.

[0026] The anti-collision mechanism 6 includes a sleeve 601, a surrounding high-strength buffer spring 602 is arranged in the sleeve 601, a main rod 604 is penetrated in the sleeve 601, and the main rod 604 passes through the surrounding high-strength buffer spring 602, an annular abutment ring 603 is arranged on the outer wall of the main rod 604, and the abutment ring 603 is located in the sleeve 601, an annular buffer pad 605 is arranged on the outer wall of the end of the main rod 604 away from the sleeve 601, and a buffer impact plate 606 is arranged on the end of the main rod 604 away from the sleeve 601. The design of the anti-collision mechanism 6 has layer-by-layer buffering and protection effects. The sleeve 601 provides soft buffer support through the surrounding high-strength buffer spring 602. The main rod 604 passes through the spring as a supporting structure and is equipped with an annular abutment ring 603 on the outside to enhance the overall stability of the structure. An annular buffer pad 605 is provided at one end of the main rod 604. This design can effectively reduce the impact force during a collision. A buffer impact plate 606 is provided at the other end to further absorb the collision energy and protect the overall structure from damage. Through these layered designs, the anti-collision mechanism 6 can provide efficient buffering and protection, ensuring that related components are effectively protected from damage in the event of a collision.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
