[0002] A pier is a building that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutments are provided on both sides of the bridge, and the piers are between the two abutments. As the main support of the bridge, the pier is an important part of the bridge structure. People usually set a layer of guardrail around the pier to protect the pier.

[0003] After retrieval, the publication number is CN215977015, and the name is a bidirectional splicing type steel structure guardrail, including a guardrail structure. Through research and analysis, it is found that although it has advantages such as not being easy to fall off during use, to a certain extent, there are still the following disadvantages.

[0004] For example, it does not have the function of quick assembly. Traditional guardrails need to be spliced by bolts, and the splicing process is complex and time-consuming. At the same time, it does not have a buffering function. When a vehicle hits the guardrail, the energy absorption ability is weak and the protection performance is poor. The guardrail is easy to twist and deform, and the vehicle is easy to rush out of the guardrail and cause casualties. To solve the above technical problems, we designed a high-speed rail pier steel structure guardrail that can be quickly assembled. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-speed rail pier steel structure guardrail that can be quickly assembled, which has the advantages of quick assembly function and buffering function, and solves the problems that the existing steel structure guardrail cannot be quickly installed and used during the use process, and cannot shock and buffer when a vehicle collides.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high-speed rail pier steel structure guardrail that can be quickly assembled, including an I-shaped steel frame. The tops of both sides of the inner cavity of the I-shaped steel frame are both connected with an adjusting mechanism through bolts. The adjusting mechanism includes a frame body. On the opposite sides of the inner cavity of the frame body, a first spring is connected through bolts. On the opposite sides of the first spring, a connecting column is riveted. The inner cavity of the I-shaped steel frame is movably connected with a buffering mechanism. The buffering mechanism includes a guardrail frame. On both sides of the inner cavity of the guardrail frame, cylinders are connected through bolts. An anti-collision ring is fixedly connected to the surface of the cylinder. A damper is fixedly connected to the rear side of the anti-collision ring. A corrugated steel plate is fixedly connected to the rear side of the damper.

[0007] Preferably, a handle is connected to the top of the connecting column through bolts, and the number of the anti-collision rings is several.

[0008] Preferably, through holes are opened at the tops and bottoms of both sides of the guardrail frame, and the opposite ends of the connecting columns all extend into the inner cavities of the through holes.

[0009] Preferably, connection blocks are connected to the top and bottom of the inner cavity of the guardrail frame through bolts, and the opposite sides of the connection blocks are fixedly connected to the anti-collision rings.

[0010] Preferably, grooves are provided at the top and bottom of both sides at the rear of the I-shaped steel frame, second springs are riveted to the front side of the inner cavity of the grooves, and the rear ends of the second springs are in contact with the corrugated steel plates.

[0011] Preferably, a support column is riveted to the bottom of the I-shaped steel frame, and a base is riveted to the bottom of the support column.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the cooperation of the handle, connecting column, first spring, frame body, through hole and I-shaped steel frame, the present utility model has a fast assembly function. The user pulls the handle, and the handle drives the connecting column to move to the opposite side. The rear end of the connecting column moves away from the through hole. The user moves the guardrail frame into the inner cavity of the I-shaped steel frame. After the movement is completed, the user stops pulling the handle, and the connecting column drives the handle to move to the opposite side. The opposite ends of the connecting column enter the through hole to fix the guardrail frame.

[0014] 2. Through the cooperation of the corrugated steel plate, second spring, damper, anti-collision ring, connection block and cylinder, the present utility model has a buffering function. When the corrugated steel plate is collided, the corrugated steel plate squeezes the second spring, causing the corrugated steel plate to move towards the I-shaped steel frame. At the same time, the damper deforms to further absorb and reduce the impact force, and the remaining impact force is transmitted to the anti-collision ring, and the anti-collision ring absorbs the remaining impact force.
