[0001] This utility model relates to the field of urban road traffic, and in particular to a protective device for bridge piers on urban roads. Background Technology

[0002] In urban road traffic systems, bridges are key infrastructure that crosses obstacles such as valleys and rivers. The safety of bridge piers is of paramount importance. As structures that support the bridge structure, bridge piers bear the core load-bearing function in the bridge system. They come in various types, such as common column piers and solid piers, and their shapes are designed to be circular, rectangular, etc., depending on different engineering needs.

[0003] my country has a complex topography, resulting in a large number of bridges that are widely distributed. Among bridges spanning rivers, column piers are the most common.

[0004] However, in actual navigation, ship operators are often unfamiliar with the road conditions or lack concentration, leading to frequent collisions with bridge piers. Traditional pier protection methods often involve placing brightly colored buoys around the piers. These buoys only serve a warning function and cannot buffer the impact of ships. Ships can still collide with the piers at high speed and with considerable force, resulting in damage to both the piers and the ships, and even causing serious loss of life and property.

[0005] Therefore, a protective device for bridge piers on urban roads is proposed to solve the above problems. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a protective device for bridge piers on urban roads, which aims to improve the problem caused by the existing technology that relies solely on buoy warnings for pier protection and cannot buffer impact forces.

[0014] As a further description of the above technical solution:

[0015] One end of the torsion spring is fixedly connected to the outer wall of the rotating shaft, and the other end of the torsion spring is fixedly connected to the inner wall of the mounting block. The rotating shaft is rotatably connected to the inner wall of the mounting block.

[0016] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Referring to Figures 1 and 2, one embodiment of this utility model is provided: a protective device for bridge piers of urban roads, including a pier body 1 for supporting the bridge structure. The pier body 1 is often installed on rivers or land. The pier body 1 located in a river may be scraped by passing ships at night. The outer wall of the pier body 1 is provided with a stress-relief component 2, which can disperse the impact force of the ship collision, effectively reduce the impact, and reduce the damage to the ship and the pier body 1. The outer wall of the stress-relief component 2 is provided with a buffer component 3, which can further reduce the impact and prevent damage to the ship and the pier body 1.

[0033] Referring to Figures 2-4, the buffer assembly 3 includes a fixed block 31. The inner wall of the fixed block 31 is elastically connected to a slider 33 via a compression spring 32. The slider 33 is located in the middle of the fixed block 31. A connecting block 34 is fixedly connected to the left surface of the slider 33. An mounting block 35 is fixedly connected to the left surface of the connecting block 34. The slider 33, connecting block 34, and mounting block 35 move synchronously. The inner wall of the mounting block 35 is elastically connected to a rotating shaft 37 via a torsion spring 36. When the rotating shaft 37 rotates, it compresses the torsion spring 36 to generate a reaction force. A connecting plate 38 is fixedly connected to the outer wall of the rotating shaft 37. Multiple sets of slider 33, connecting block 34, mounting block 35, torsion spring 36, rotating shaft 37, and connecting plate 38 are provided, arranged in a circular array with the center point of the pier body 1 as the center, and connected in pairs via connecting plates 38 to form a ring. The two ends of the rotating shaft 37 and the connecting plate 38 are connected. When the rotating shaft 37 rotates, it can drive the connecting plate 38 to swing, thereby dispersing the impact force.

[0034] Referring to Figures 1-2, the unloading assembly 2 includes a mounting ring 21, and a support plate 22 is rotatably connected to the lower surface of the mounting ring 21. There are two sets of mounting rings 21, which are symmetrically distributed vertically around the center line of the support plate 22. A baffle 23 is fixedly connected to the left surface of the mounting block 35.

[0035] Referring to Figures 2-4, one end of the compression spring 32 is fixedly connected to the right surface of the slider 33, and the other end of the compression spring 32 is fixedly connected to the inner wall of the right side of the fixing block 31. The slider 33 is slidably connected to the inner wall of the fixing block 31. When the slider 33 moves to the right, it will compress the compression spring 32 to generate a reaction force. When the slider 33 moves to the left, it will stretch the compression spring 32 to generate a reaction force. The connecting block 34 is slidably connected to the left surface of the fixing block 31. The outer wall of the connecting block 34 fits against the fixing block 31 to prevent river water from seeping in. One end of the torsion spring 36 is fixedly connected to the outer wall of the rotating shaft 37, and the other end of the torsion spring 36 is fixedly connected to the inner wall of the mounting block 35. The rotating shaft 37 is rotatably connected to the inner wall of the mounting block 35. Notches are provided at the front and rear ends of the right surface of the mounting block 35. The two ends of the connecting plate 38 are located at the notches to avoid obstruction.

[0036] Referring to Figures 1-2, the mounting ring 21 is fixedly connected to the outer wall of the pier body 1 by bolts. The inner wall of the support plate 22 is in contact with the outer wall of the pier body 1. The baffle 23 is set in an arc shape, which can reduce the contact area when the ship collides. The baffle 23 will rotate when impacted, dispersing the force. The right surface of the fixing block 31 is fixedly connected to the left surface of the support plate 22.

[0037] Working principle: When the ship hits the protective device, it first hits the baffle 23 of the force-dissipating component 2. After the baffle 23 is hit, the impact force will be transmitted. Since the impact force is not transmitted in a completely linear manner, the baffle 23, the buffer component 3 and the support plate 22 will rotate.

[0038] Furthermore, the impacted baffle 23 will move, which in turn will cause the mounting block 35 and the connecting block 34 to move synchronously. The connecting block 34 will then cause the slider 33 to slide within the fixed block 31. When the slider 33 slides, it will squeeze or stretch the compression spring 32 connected to it. The reaction force generated by the compression spring 32 will buffer the impact force, reduce the impact speed and force of the ship, and reduce the impact on the pier body 1.

[0039] Simultaneously, the movement of the mounting block 35 causes the rotating shaft 37 to rotate. During the rotation of the rotating shaft 37, the torsion spring 36 is compressed, and the reaction force generated by the torsion spring 36 further dissipates the impact energy. Furthermore, since the rotating shaft 37 and the connecting plate 38 are connected and multiple sets are distributed in a circular array, the rotation of the rotating shaft 37 causes the connecting plate 38 to swing, which can disperse the impact force over a larger area, avoid excessive local stress, and thus effectively protect the pier body 1 from serious damage caused by the ship collision, and also reduce the damage suffered by the ship itself due to the collision with the pier.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
