Description

Technical Field

[0001] This utility model relates to the field of bridge engineering protection technology, specifically a bridge pier protection device. Background Technology

[0002] In bridge engineering, bridge piers and abutments are key components supporting the superstructure of bridges. Their safety and stability are directly related to the operational safety of the entire bridge. Bridge piers and abutments are exposed to the natural environment for a long time. They not only have to bear the weight of the bridge itself and the load of passing vehicles, but also external forces such as accidental impacts from ships or vehicles. Therefore, setting up effective protective devices for bridge piers and abutments to resist external impacts is an important measure to ensure the safe operation of bridges. In existing technologies, bridge pier protection devices typically employ fixed rigid or elastic structures. The buffer surfaces of these devices face a fixed direction and cannot be adjusted according to the actual impact angle of vehicles or ships. For example, when facing impacts from vehicles or ships from different directions, the buffer surfaces cannot be perpendicular to the impact direction, preventing the protective device from fully utilizing its impact resistance performance and effectively absorbing impact energy. This affects the protection effect on the piers and abutments. Such fixed-structure protection devices have poor adaptability and are difficult to cope with complex and changing actual working conditions, reducing the reliability of bridge pier protection. Therefore, a bridge pier protection device is proposed to solve the above problems. Summary of the Invention

[0006] Furthermore, a support shaft is rotatably mounted on the hinge seat, and a connecting frame is fixedly mounted on the middle of one side of both the first protective module and the second protective module. The connecting frame is hinged to the hinge seat through the support shaft.

[0012] 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.

[0013] Please see Figures 1-5 The bridge pier protection device in this embodiment includes protection components installed on the four sides of the bottom of the pier body 1. The protection components include multiple protection modules 1 2 and multiple protection modules 2 3. Each protection module 1 2 and each protection module 2 3 is hinged to a gas spring 11 on the side opposite to the pier body 1. Each of the four sides of the pier body 1 is provided with a hinge seat 13.

[0014] First, the protective components are arranged around the lower sides of the pier body 1. This layout can cover the critical areas of the pier that are vulnerable to impact in all directions, forming the first line of defense. The protective components consist of multiple protective modules 1 2 and multiple protective modules 2 3. A connector 21 is fixedly installed on the side of protective module 1 2 near protective module 2 3, and a protrusion 31 is fixedly installed on the side of protective module 2 3 near protective module 1 2. The connector 21 has an arc-shaped groove that matches the protrusion 31. One side of the protrusion 31 extends into the arc-shaped groove. This connection method allows adjacent modules to rotate relative to each other. When impacted by forces from different directions, the modules can adjust their angles through the cooperation of the arc-shaped groove and the protrusion 31 to ensure that the buffer surface is as perpendicular as possible to the impact direction, thereby improving the impact resistance. Secondly, hinge seats 13 are provided on all four sides of the pier body 1. Support shafts are rotatably installed on the hinge seats 13. Connecting frames 32 are fixedly installed on the middle of one side of both the first protective module 2 and the second protective module 3. The connecting frames 32 are hinged to the hinge seats 13 through the support shafts. This hinge structure is the core of the module angle adjustment, which allows the first protective module 2 and the second protective module 3 to rotate flexibly around the support shafts. When subjected to impact forces from different directions, the modules can rotate around the hinge seats 13. With the arc-shaped cooperation of the connector 21 and the protrusion 31, the buffer surface can be adjusted at multiple angles, solving the problem of the fixed orientation of the buffer surface in the existing device.

[0015] When the module is impacted and rotates, the gas spring 11 will extend and retract accordingly. The high-pressure gas inside is compressed or expanded, and the resulting buffering force can effectively buffer the module and absorb some of the impact energy. At the same time, after the impact ends, the restored air pressure inside the gas spring 11 will form a restoring force, driving itself and the module back to the initial position.

[0016] Each protective module 1 2 and each protective module 2 3 has a buffer cavity inside, which is filled with buffer material, including an outer elastic rubber layer 41, a middle honeycomb metal layer 42 and an inner shape memory alloy skeleton 43. The elastic rubber layer 41 is located near the outer side of the module. It is soft and elastic and can make contact with the impacting object first. It absorbs part of the impact energy through its own deformation and reduces the impact force of the impacting object on the module. The honeycomb metal layer 42 is located in the middle. Its honeycomb structure has good compressive strength and energy absorption performance. When subjected to impact force, the honeycomb structure will be compressed and deformed, further absorbing a large amount of energy. The shape memory alloy skeleton 43 is located near the inner side of the module. It has a shape memory effect. After being deformed by a large impact, it can restore its original shape under certain conditions, providing structural support for the module and ensuring its overall stability.

[0017] During the use of the device, when a vehicle or ship impacts the first protective module 2 or the second protective module 3 from a certain direction, the connector 21 of the first protective module and the protrusion 31 of the second protective module 3 will slide relative to each other along the arc groove. With the rotation of the connecting frame 32 and the hinge seat 13, the protective module can quickly adjust its angle to cope with the impact. At this time, the gas spring 11 will extend and retract with the rotation of the module. Its output stable buffering force, together with the deformation energy absorption of the elastic rubber layer 41, honeycomb metal layer 42 and shape memory alloy skeleton 43 inside the protective module, greatly improves the overall impact resistance. After the impact, the restoring force of the gas spring 11 drives the module to reset, and the connector 21 and the protrusion 31 also return to the initial mating position, ensuring that the device can cope with the next possible impact at any time.

[0018] In summary, this bridge pier protection device, through the connection 21 of the first protection module 2 and the arc-shaped groove of the protrusion 31 of the second protection module 3, and the hinge structure of the protection module with the hinge seat 13 through the connecting frame 32, allows the protection module to flexibly adjust its angle according to the impact direction, ensuring that the buffer surface is always as perpendicular as possible to the impact direction. This allows the impact resistance performance of the first protection module 2 and the second protection module 3 to be fully utilized, significantly improving the protection effect on the pier body 1 and enhancing the adaptability of the device to complex and variable working conditions. Furthermore, the elastic rubber layer 41, the honeycomb metal layer 42, and the shape memory alloy skeleton 43 constitute a multi-layer buffer structure that can absorb impact energy step by step; the gas spring 11 further enhances the buffering effect, and the gas spring 11 can drive the module to reset, ensuring the reusability of the device. These structures work together to effectively resist accidental impacts from ships or vehicles, ensuring the safety and stability of bridge piers.
