Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge construction, and in particular to a highway bridge reinforcement structure. Background Technology
[0002] As bridges age, their structural performance gradually declines, especially for severely damaged components that require timely replacement and reinforcement. Traditional methods of replacing bridge components often involve frequent disassembly of fasteners, a process that can easily weaken their clamping force, thus affecting the bridge's structural safety. While various advanced reinforcement and repair techniques have emerged in recent years to address this issue, the problem of weakened fastener clamping force persists, directly impacting the bridge's service life and safety.
[0003] Therefore, existing bridge reinforcement methods urgently need improvement to reduce the adverse effects of frequent disassembly of fasteners on structural performance. Currently, various reinforcement methods mainly rely on traditional fastener connections, which not only increases operational complexity but may also reduce the reliability of fasteners due to repeated disassembly. Utility Model Content
[0004] This utility model solves the problems in related technologies and proposes a highway bridge reinforcement structure. First, a locking post penetrates the mounting panel to ensure a stable connection between the locking post and the mounting panel. Then, a fixing mechanism secures the locking sleeve and locking post in the appropriate position. The locking sleeve clamps and fixes the component to be replaced, thereby effectively ensuring the stability of the connection between the component to be replaced and the mounting panel, and ensuring the safety and reliability of the equipment during use.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a highway bridge reinforcement structure, including a mounting panel, a replacement component connected to the mounting panel, and a fastener for fixing the replacement component to the mounting panel;
[0006] The fastener includes a locking pin connected to the mounting panel, elastic claws evenly distributed around one end of the locking pin, a locking sleeve disposed around the locking pin, and a fixing mechanism disposed between the locking pin and the locking sleeve.
[0007] By adopting the above technical solution, the locking pin first penetrates the mounting panel, ensuring a stable connection between the locking pin and the mounting panel. Then, the fixing mechanism secures the locking sleeve and locking pin in the appropriate position, using the locking sleeve to clamp and fix the component to be replaced. This effectively ensures the stability of the connection between the component to be replaced and the mounting panel, guaranteeing the safety and reliability of the equipment during use.
[0008] As a preferred embodiment, the fixing mechanism includes a locking bolt fixedly disposed at the other end of the locking pin, limiting protrusions evenly disposed around the outer periphery of the locking bolt, limiting baffles evenly disposed on the inner wall of the locking sleeve, a relief groove disposed between adjacent limiting baffles and adapted to the limiting protrusions, a limiting post disposed on the inner wall of the locking sleeve for limiting the limiting protrusions, and an elastic element disposed at the connection between the limiting post and the locking sleeve.
[0009] By adopting the above technical solution, the connection stability is enhanced by a locking bolt fixedly installed at the other end of the locking pin. The evenly distributed limiting protrusions on the outer circumference of the locking bolt cooperate with the limiting baffle and relief groove on the inner wall of the locking sleeve to ensure stable positioning of the locking pin within the locking sleeve. The limiting pin and the elastic element at its connection point provide additional support force to prevent the limiting protrusions from shifting during locking. In this way, the user can easily remove the locking sleeve by rotating it, allowing the limiting protrusions to slide into the relief groove, facilitating the replacement of the component. This design not only provides high connection reliability but also greatly facilitates disassembly and assembly operations, improving the convenience of maintenance and component replacement.
[0010] As a preferred embodiment, the cross-section of each elastic claw is set as a right-angled triangle, and the outer diameter of the elastic claw increases sequentially along its height direction.
[0011] By adopting the above technical solution, the cross-section of each elastic claw is designed as a right-angled triangle, which facilitates tight insertion into the holes of the mounting panel, increases the contact area, and enhances the fixing effect. The outer diameter of the elastic claw gradually increases from the bottom to the top, increasing the adaptability and flexibility during insertion, ensuring that it can pass smoothly and be fastened to the mounting panel. This design can better distribute the force during installation, improving the support effect. When replacing the component, the force exerted by the component on the elastic claw disappears, and the locking pin moves slightly upward, thus facilitating the installation of the new component. By using the locking sleeve to fix the locking pin during installation, quick and easy component replacement is achieved.
[0012] As a preferred embodiment, the elastic element includes a sliding groove disposed inside the locking sleeve and a telescopic spring disposed inside the sliding groove and connected to the limiting post. One end of the telescopic spring is fixedly connected to the limiting post, and the other end of the telescopic spring is fixedly connected to the inner cavity of the sliding groove.
[0013] By adopting the above technical solution, the locking sleeve has a sliding groove inside, and a telescopic spring connected to the limiting post is installed in the sliding groove. One end of the telescopic spring is fixed to the limiting post, and the other end is fixed to the inner wall of the sliding groove. The function of the telescopic spring is to provide support and assistance, facilitating the free sliding of the limiting post within the sliding groove. Specifically, the telescopic spring can provide necessary elastic support when the limiting post slides, ensuring that the limiting post can move smoothly within the sliding groove, and also provides a reaction force for its movement, which helps to stabilize the working state of the limiting post.
[0014] As a preferred embodiment, the outer periphery of the end of the limiting post that is away from the end connected to the telescopic spring is rounded, and a buffer washer is provided on its outer rounded surface.
[0015] By adopting the above technical solution, the outer periphery of the end of the limiting post furthest from the telescopic spring is designed in an arc shape, and a buffer washer is set on its arc surface. This allows for a smoother limiting operation on the limiting protrusion, effectively avoiding impact and wear that may be caused by direct contact. The telescopic spring provides the restoring force, ensuring that the locking post automatically returns to its original position when not in use. The locking post and locking sleeve achieve a stable fixed state through the limiting action of the limiting post, ensuring accurate positioning during unlocking operations.
[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model;
[0017] The locking pin connects the part to be replaced to the mounting panel and provides a stable fixing point to ensure that the part to be replaced is installed securely.
[0018] The elastic claws are evenly distributed at one end of the locking pin, providing additional clamping force to secure the replacement part more firmly to the mounting panel;
[0019] The fixing mechanism is used to lock the locking sleeve and locking pin in a fixed position to ensure that the part to be replaced will not loosen due to external force. Attached Figure Description

[0033] like Figures 1 to 5 As shown, a highway bridge reinforcement structure includes a mounting panel 1, a replacement component 2 connected to the mounting panel 1, and a fastener 3 for fixing the replacement component 2 to the mounting panel 1.
[0034] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing component 3 includes a locking pin 41 connected to the mounting panel 1, elastic claws 412 evenly distributed around one end of the locking pin 41, a locking sleeve 42 disposed around the locking pin 41, and a fixing mechanism disposed between the locking pin 41 and the locking sleeve 42. The locking pin 41 penetrates through the mounting panel 1, achieving a stable connection between the locking pin 41 and the mounting panel 1. First, the connection between the locking pin 41 and the mounting panel 1 is ensured by the locking pin 41 penetrating through the mounting panel 1. Then, the fixing mechanism fixes the locking sleeve 42 and the locking pin 41 in an appropriate position, and the locking sleeve 42 clamps and fixes the component to be replaced 2, thereby effectively ensuring the stability of the connection between the component to be replaced 2 and the mounting panel 1, and ensuring the safety and reliability of the equipment during use.
[0035] Please refer to the details. Figure 2 , Figure 3 , Figure 4 and Figure 5 The fixing mechanism includes a locking bolt 411 fixedly disposed at the other end of the locking pin 41, limiting protrusions 4111 evenly disposed around the outer periphery of the locking bolt 411, limiting baffles 421 evenly disposed on the inner wall of the locking sleeve 42, a relief groove 4211 disposed between adjacent limiting baffles 421 and adapted to the limiting protrusions 4111, a limiting post 52 disposed on the inner wall of the locking sleeve 42 for limiting the limiting protrusions 4111, and a limiting post 52 disposed between the limiting post 52 and the locking sleeve 42. The elastic element at the connection point enhances the stability of the connection through the locking bolt 411 fixedly installed at the other end of the locking pin 41. The evenly distributed limiting protrusions 4111 on the outer periphery of the locking bolt 411 cooperate with the limiting baffle 421 and the relief groove 4211 on the inner wall of the locking sleeve 42 to ensure the stable positioning of the locking pin 41 within the locking sleeve 42. The limiting pin 52 and the elastic element at its connection point provide additional support to prevent the limiting protrusions 4111 from shifting during locking. In this way, the user can easily remove the locking sleeve 42 by rotating it, allowing the limiting protrusions 4111 to slide into the relief groove 4211, facilitating the replacement of the component. This design not only provides high connection reliability but also greatly facilitates disassembly and assembly operations, improving the convenience of maintenance and component replacement.
[0036] Please refer to the details. Figure 5Each elastic claw 412 has a right-angled triangular cross-section, and its outer diameter increases sequentially along its height. This triangular cross-section facilitates tight insertion into the holes of the mounting panel 1, increasing the contact area and enhancing the fixing effect. The outer diameter of the elastic claw 412 gradually increases from the bottom upwards, increasing its adaptability and flexibility during insertion, ensuring smooth passage and secure fastening to the mounting panel 1. This design better disperses the force during installation, improving support. When replacing the component 2, the force exerted by the component 2 on the elastic claw 412 disappears, and the locking pin 41 moves slightly upwards, facilitating the installation of the new component. By using the locking sleeve 42 to fix the locking pin 41 during installation, quick and easy component replacement is achieved. In terms of working principle, the unique cross-section and gradually increasing outer diameter design of the elastic claw 412 ensures the stability of the installation and the convenience of replacement, making the assembly and maintenance of the entire system more efficient and simple.
[0037] Please refer to the details. Figure 2 , Figure 3 and Figure 4 The elastic element includes a groove 51 disposed inside the locking sleeve 42 and a telescopic spring 521 disposed inside the groove 51 and connected to the limiting post 52. One end of the telescopic spring 521 is fixedly connected to the limiting post 52, and the other end of the telescopic spring 521 is fixedly connected to the inner cavity of the groove 51. The locking sleeve 42 has a groove 51 inside, and the telescopic spring 521 connected to the limiting post 52 is installed in the groove 51. One end of the telescopic spring 521 is fixed to the limiting post 52, and the other end is fixed to the inner wall of the groove 51. The function of the telescopic spring 521 is to provide support and assistance, so that the limiting post 52 can slide freely in the groove 51. Specifically, the telescopic spring 521 can provide necessary elastic support when the limiting post 52 slides, ensuring that the limiting post 52 can move smoothly in the groove 51, and also provides a reaction force for its movement, which helps to stabilize the working state of the limiting post 52. In terms of working principle, by setting a slide groove 51 and a telescopic spring 521 in the locking sleeve 42, the limiting post 52 of the device can achieve flexible telescopic movement.
[0038] Please refer to the details. Figure 2 and Figure 3The outer periphery of the limiting post 52, away from the end connected to the telescopic spring 521, is rounded, and a buffer washer is provided on its outer rounded surface. This design allows for smoother positioning of the limiting protrusion 4111, effectively avoiding impact and wear that may be caused by direct contact. The telescopic spring 521 provides the restoring force, ensuring that the locking post 41 automatically returns to its original position when not in use. The locking post 41 and the locking sleeve 42 achieve a stable fixed state through the limiting action of the limiting post 52, ensuring accurate positioning during unlocking operations.
[0039] In this embodiment, during use, the locking sleeve 42 is placed on the upper surface of the component to be replaced. The locking pin 41 passes through the locking sleeve 42 in sequence and connects to the mounting panel 1, ensuring a stable connection between the locking pin 41 and the mounting panel 1. The elastic claw 412, with its unique cross-section and gradually increasing outer diameter design, ensures the stability of the installation and the convenience of replacement. During this process, the limiting protrusion 4111 is placed on the limiting baffle 421. The telescopic spring 521 can provide necessary elastic support when the limiting pin 52 slides, ensuring that the limiting pin 52 can move smoothly in the slide groove 51. At the same time, it also provides a reaction force for its movement, which helps to stabilize the working state of the limiting pin 52 and avoids the locking sleeve 42 from shifting position.
[0040] During disassembly and assembly, simply rotate the locking sleeve 42 to allow the limiting protrusion 4111 to slide into the relief groove 4211, thereby easily removing the locking sleeve 42 and facilitating the replacement of the component to be replaced.
[0041] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
