Description

Technical Field

[0001] This utility model relates to a safety crash barrier, specifically a high-strength, high-speed rotating barrier. Background Technology

[0002] High-speed rotating guardrails are a type of rotating safety crash barrier that prevents out-of-control vehicles from crossing the protected area of ​​a highway and leaving the driving lane. They also reduce the damage to vehicles and people in accidents and are widely used on highways.

[0003] High-speed rotating guardrails typically consist of multiple posts fixed to the ground at intervals, two horizontal beams fixed to the top and bottom of the posts respectively, and a rotating barrel rotatably connected to each post between the two horizontal beams. The height of the rotating barrel is the same as the distance between the two horizontal beams. When a high-speed rotating guardrail is impacted by a vehicle, the rotating barrel can absorb the impact energy and guide out-of-control vehicles back to their normal driving trajectory, minimizing or reducing personal injury and property damage in traffic accidents. However, existing high-speed rotating guardrails only have two horizontal beams with a relatively large distance between them, resulting in a relatively high rotating barrel. Furthermore, the rotating barrel lacks reinforcing components to increase its structural strength. When impacted by a vehicle, the existing rotating barrel has insufficient impact resistance and is prone to deformation and damage, seriously affecting the safety of the high-speed rotating guardrail during use. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a high-strength, high-speed rotating guardrail to improve impact resistance and enhance safety during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-strength, high-speed rotating guardrail includes at least two uprights fixed to the ground at intervals, multiple horizontal beams fixed at intervals between adjacent uprights, multiple vertical shafts fixed through the multiple horizontal beams, the multiple vertical shafts being arranged at intervals along the length direction of the horizontal beams, and a rotating barrel being provided on each vertical shaft at a position between adjacent horizontal beams; the rotating barrel includes a shell rotatably connected to the vertical shaft and a reinforcing tube assembly located inside the shell rotatably connected to the vertical shaft.

[0006] As a limitation of this utility model, the outer shell includes a lower shell rotatably connected to a vertical shaft, an upper shell rotatably connected to the vertical shaft and located above the lower shell, and a middle shell inserted between the lower shell and the upper shell; the lower shell and the upper shell have the same structure and size, and the middle shell is adapted to the size of the lower shell and the upper shell so that the middle shell is fixedly connected to the lower shell and the upper shell together.

[0007] As another limitation of this utility model, the reinforcing tube assembly includes a vertical connecting tube rotatably connected to a vertical shaft and a plurality of vertical reinforcing tubes fixed on the periphery of the outer wall of the vertical connecting tube, wherein the plurality of vertical reinforcing tubes are sequentially fixedly connected together to form a closed loop.

[0008] As a further limitation of this utility model, the horizontal beam includes a first horizontal tube fixed between two adjacent columns, a second horizontal tube fixed side by side on the first horizontal tube, and at least one reinforcing plate vertically fixed in the cavity of the first horizontal tube; the vertical shaft passes through all the second horizontal tubes from top to bottom and the two ends of the vertical shaft are respectively fixed on the corresponding second horizontal tubes.

[0009] As a third limitation of this utility model, the column includes a square tube, four corner round tubes fixed at the four corner positions inside the cavity of the square tube, and a central round tube located at the middle position inside the cavity of the square tube and fixedly connected to the outer walls of the four corner round tubes.

[0010] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0011] (1) This utility model is provided with multiple horizontal beams and multiple vertical shafts. Each vertical shaft is provided with a rotating barrel at the position between two adjacent horizontal beams. Compared with the prior art, since this utility model is provided with multiple horizontal beams, the distance between two adjacent horizontal beams becomes smaller, the height of the rotating barrel becomes smaller, and the rigidity of the rotating barrel becomes larger. When subjected to impact force, the rotating barrel is not easily deformed. Furthermore, the rotating barrel in this utility model is provided with a reinforcing tube assembly. The reinforcing tube assembly can improve the structural strength of the rotating barrel and improve the impact resistance of the rotating barrel, thereby effectively improving the safety of this utility model.

[0012] (2) The rotating barrel in this utility model includes an outer shell and a reinforcing tube assembly. The outer shell is composed of an upper shell, a middle shell and a lower shell. When the rotating barrel is damaged, it is not necessary to replace the entire rotating barrel. Only the damaged part of the rotating barrel needs to be replaced. The maintenance cost is lower, which can effectively reduce the cost of use and improve the practicality of this utility model.

[0013] (3) The reinforcing tube assembly of this utility model includes a vertical connecting tube and multiple vertical reinforcing tubes. The vertical connecting tube and multiple vertical reinforcing tubes are combined to form a grid-like structure. This grid-like structure is lightweight and has high strength, which can effectively improve the strength of the rotating barrel structure. In addition, the reinforcing tube assembly can convert the impact force into rotational kinetic energy, absorb the impact force, and guide the vehicle to move, preventing the vehicle from leaving the driving lane.

[0014] (4) The horizontal beam in this utility model adopts a structure combining a first horizontal tube, a second horizontal tube and a reinforcing plate. The overall structural strength of the horizontal beam is higher, which can effectively improve the anti-collision performance of this utility model.

[0015] (5) The column in this utility model is composed of a square tube, four corner round tubes and a central round tube. This structure has low manufacturing cost and high strength, which can effectively improve the overall strength of the structure of this utility model.

[0016] In summary, this utility model boasts high structural strength, high safety, and strong practicality. The rotating barrel in this utility model incorporates reinforcing tube components and exhibits high rigidity, resulting in high structural strength. Furthermore, the uprights utilize a combination of square tubes, four corner round tubes, and a central round tube, while the horizontal beams employ a combination of first and second horizontal tubes and reinforcing plates. This significantly enhances the structural strength of both the uprights and horizontal beams, thereby improving the overall structural strength of the utility model and effectively enhancing its impact resistance and safety. This utility model is suitable for installation along highways as a safety crash barrier. Attached Figure Description
