Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision blocks, and specifically, to an anti-collision block for a bridge guardrail with a shock-absorbing function. Background Technique

[0002] The anti-collision block is a load-bearing component between the corrugated beam and the column of the roadside corrugated beam guardrail. It is a hexagonal hollow tube with a wall thickness of about 4.5 millimeters. When subjected to a huge impact force, the anti-collision block will naturally deform and absorb the impact force brought by the collision. It is applicable to sections where the vehicle types in the traffic flow are relatively complex and there is a concern that the colliding vehicle may be blocked at the guardrail column.

[0003] The anti-collision block relies on itself to reduce vibration. However, the impact force caused by vehicle collision is generally relatively large. Without a shock-absorbing mechanism, it is difficult to reduce vibration and protect the guardrail. If the guardrail is directly damaged, very serious consequences may occur.

[0004] Therefore, we urgently need to provide an anti-collision block for a bridge guardrail with a shock-absorbing function. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an anti-collision block for a bridge guardrail with a shock-absorbing function, which solves the problem of not being able to better reduce vibration.

[0006] To achieve the above purpose, the utility model provides the following technical solution. An anti-collision block for a bridge guardrail with a shock-absorbing function adopts the following technical solution: It includes an installation chassis, a support column is fixedly connected to the bottom of the installation chassis, an installation block is fixedly connected to the outer wall of the support column, and a second bolt is threadedly connected to the inner wall of the installation block;

[0007] The installation block installs an anti-collision block body through the second bolt. A first bolt is threadedly connected to the inner wall of the anti-collision block body. The anti-collision block body installs a guardrail plate through the first bolt. A shock-absorbing component is arranged on the inner wall of the anti-collision block body.

[0008] As a preferred solution, the shock-absorbing component includes a shock-absorbing sleeve. A damping block is fixedly installed on the inner wall of the shock-absorbing sleeve. One side of the damping block is fixedly connected to a telescopic spring. One end of the telescopic spring is fixedly connected to a buffer plate. One side of the buffer plate is fixedly connected to a buffer rod, and one end of the buffer rod is fixedly connected to the inner wall of the anti-collision block body.

[0009] As a preferred solution, one end of the buffer rod penetrates through the inner wall of the shock-absorbing sleeve and extends to the outer wall of the shock-absorbing sleeve, and the outer wall of the buffer rod is movably connected to the inner wall of the shock-absorbing sleeve.

[0010] As a preferred solution, a chute is provided on the inner wall of the shock-absorbing sleeve. Both sides of the buffer plate are fixedly connected with sliders, and the outer wall of the slider is slidably connected with the inner wall of the chute.

[0011] As a preferred solution, a shock isolation layer is provided on the inner wall of the anti-blocking block body, and the shock isolation layer is a damping alloy shock isolation layer.

[0012] As a preferred solution, one end of the second bolt penetrates through the outer wall of the anti-blocking block body and extends to the inner wall of the anti-blocking block body, and the outer wall of the second bolt is threadedly connected with the inner wall of the anti-blocking block body.

[0013] Compared with the prior art, the utility model provides an anti-blocking block for a bridge anti-collision guardrail with a shock-absorbing function, and has the following beneficial effects:

[0014] 1. Through the mutual cooperation of the shock isolation layer, buffer rod, buffer plate, telescopic spring and damping block provided by the utility model, when subjected to external vibration, the shock isolation layer on the inner wall of the anti-blocking block body can play a certain role in shock isolation. If the force is too large, it will also squeeze the guardrail plate, thereby squeezing the anti-blocking block body. The anti-blocking block body transmits the force generated by the vibration extrusion to the buffer rod, and the buffer rod squeezes the damping block through the buffer plate and the telescopic spring. The damping block can reduce the vibration and drive the telescopic spring to generate a reaction force, reducing the vibration, which achieves a better purpose of reducing vibration and makes the anti-blocking block more protective.

[0015] 2. Through the mutual cooperation of the second bolt, mounting block and first bolt provided by the utility model, the anti-blocking block body is installed through the second bolt and the mounting block, and the first bolt can install the anti-blocking block body and the guardrail plate. This achieves the purpose of facilitating installation and disassembly, so that the guardrail plate or the anti-blocking block body can be replaced in time when damaged, reducing the working pressure of people.

Through the mutual cooperation of the shock insulation layer 15, the buffer rod 10, the buffer plate 7, the telescopic spring 9 and the damping block 8, when subjected to external vibrations, the shock insulation layer 15 on the inner wall of the anti-blocking body 3 can play a certain role in shock insulation. If the force is too large, it will also squeeze the guardrail plate 5, thereby squeezing the anti-blocking body 3. The anti-blocking body 3 transmits the force generated by the vibration extrusion to the buffer rod 10. The buffer rod 10 squeezes the damping block 8 through the buffer plate 7 and the telescopic spring 9. The damping block 8 can reduce the vibration and drive the telescopic spring 9 to generate a reaction force, reducing the vibration.

[0027] Embodiment 2

[0028] Please refer to Figures 1-4 , based on the same concept as the above Embodiment 1, this embodiment also proposes that one end of the buffer rod 10 penetrates through the inner wall of the shock-absorbing sleeve 4 and extends to the outer wall of the shock-absorbing sleeve 4, and the outer wall of the buffer rod 10 is movably connected to the inner wall of the shock-absorbing sleeve 4.
