Description

Technical Field

[0001] This utility model relates to the technical field of municipal bridge anti-collision wall technology, specifically a municipal bridge anti-collision wall. Background Technology

[0002] Municipal bridges are an important part of urban infrastructure. They not only cross natural obstacles such as rivers and valleys, but also connect different areas of the city, providing important channels for urban traffic. Their main function is to ensure smooth traffic on the bridge, while ensuring that the flow of water or the passage of vehicles under the bridge is not affected. Municipal bridges generally consist of four basic parts: superstructure, substructure, bearing system, and ancillary facilities.

[0003] The edges of the bridge decks of municipal bridges are usually equipped with crash barriers along the extension direction of the bridge. These barriers form a solid barrier that can effectively resist damage to the main structure of the bridge from external forces such as vehicle collisions, ensuring the stability and safety of the bridge structure. In the event of a vehicle collision with the bridge, the crash barriers can absorb and disperse the impact energy, reducing the degree of damage to the bridge structure and thus protecting the integrity and stability of the main bridge structure.

[0004] Current crash barriers are usually constructed as a single unit, cast directly onto the top of the bridge to withstand external forces such as vehicle impacts. However, during use, crash barriers are susceptible to damage from vehicle collisions and require repair. The difficulty of repairing a single unit increases maintenance costs. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a municipal bridge crash barrier to solve the technical problem that the crash barrier is easily damaged by vehicle impacts during use, requiring maintenance. However, the integrated structure makes maintenance difficult and increases maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal bridge anti-collision wall, comprising a fixed block, wherein a plurality of columns are fixedly connected within the fixed block, and elastic blocks are movably connected between adjacent columns. Each column is provided with a groove, and a sliding rod that slidably engages with the groove is slidably connected within each groove, and the sliding rod is configured with an "L" shape. Each sliding rod and the corresponding groove are connected by a first spring. The surface of each sliding rod is provided with multiple sets of fixed grooves, and a movable rod is rotatably connected within each fixed groove via a rotating shaft. A coil spring is provided at the connection between the rotating shaft and the fixed groove. The surface of the column is provided with multiple first insertion holes that engage with the movable rod, and the surface of the elastic block is provided with multiple second insertion holes that engage with the movable rod.

[0007] By adopting the above technical solution, the basic structure of the crash barrier can be realized through the design of fixed blocks, columns, and elastic blocks. The deformation of the elastic blocks improves effective buffering, reducing the direct impact of impact forces on the bridge structure. It also increases the contact area between the crash barrier and the impacting object, helping to better disperse the impact force and thus extending the service life of the crash barrier. Furthermore, after prolonged use or impact damage to the elastic blocks, the sliding rod can be driven downwards, causing the movable rod to rotate through the first insertion hole until it disengages from the second insertion hole. This allows the elastic block to be removed from the top of the fixed block, facilitating disassembly. After replacement, releasing the driving force on the sliding rod allows the second spring to drive it upwards to return to its original position, enabling the movable rod to re-insert into the second insertion hole for securing the elastic block. This structure, through the fitting design of the movable rod with the first and second insertion holes, simplifies the installation and removal of the elastic blocks, reducing maintenance costs. The position and number of elastic blocks can also be adjusted according to actual needs to adapt to different crash protection requirements.

[0008] The present invention is further configured such that a fixed frame is fixedly connected to the side of the fixed block away from the elastic block, a movable plate that fits into the fixed frame is slidably connected inside the fixed frame, and the movable plate and the fixed frame are connected by a second spring, a connecting rod is fixedly connected to both ends of the movable plate, one end of each sliding rod is fixedly connected to the surface of the connecting rod, a second limiting groove is provided on both sides of the fixed frame, and the sliding rod slides in the second limiting groove.

[0009] By adopting the above technical solution, when it is necessary to replace the elastic block, the movable plate can be stepped on to make it move downwards, thereby squeezing the second spring. This will cause the sliding rod to move downwards synchronously through the connecting rod. When the force applied to the movable plate is released, the second spring will drive the movable plate and the sliding rod to reset. Thus, the movement of the movable plate can drive the position of the sliding rod.

[0010] The present invention is further configured such that each of the elastic blocks has a groove at both ends, and a protrusion that fits into the groove is slidably connected in each groove. Each protrusion is fixedly connected to the corresponding column surface, and the protrusion is configured as a "T" shaped structure.

[0011] By adopting the above technical solution, the design of the groove and the protrusion makes it easy for the elastic block to be firmly connected between the columns and not easily detached. This structure can quickly install the elastic block and facilitate its replacement after it is damaged by impact. At the same time, the "T"-shaped structure of the protrusion increases the stability and reliability of the connection, ensuring that the crash barrier can maintain its structural integrity when it is impacted.

[0012] The present invention is further configured such that a first limiting groove is provided on one side of the fixed frame, a limiting block is slidably connected in the first limiting groove, and the limiting block is fixedly connected to one side of the movable plate.

[0013] By adopting the above technical solution, the design of the limiting groove and the limiting block can increase the stability of the moving plate within the fixed frame, making it easier to drive the connecting rod and the sliding rod to move through the moving plate, and thus increasing the stability of the overall structure.

[0014] The present invention is further configured such that each elastic block has a plurality of slots on its surface, and a roller is rotatably connected in each slot.

[0015] By adopting the above technical solutions, the design of the slot and the roller can increase the contact area between the impacting object and the crash barrier, thereby dispersing the impact force. At the same time, the design of the roller can reduce the impact force, thereby further enhancing the crash barrier's anti-collision performance.

[0016] The present invention is further configured such that the first socket is a frustum structure, and the size of the end of the first socket near the slide bar is larger than the size of the other end.

[0017] By adopting the above technical solution, when the sliding rod moves downward, it can be rotated better through the frustum structure of the first hole to disengage it from the second insertion hole. At the same time, when the sliding rod moves upward to return to its original position, the movable rod can be better inserted into the second insertion hole, which facilitates the increase of the connection strength and stability between the column and the elastic block, thereby improving the overall anti-collision performance of the crash barrier.

[0018] The present invention is further configured such that the fixing block is composed of multiple arc-shaped plates, and the position of the elastic block and the arc-shaped groove of the fixing block are matched.

[0019] By adopting the above technical solution, the fixing plate composed of multiple arc-shaped plates forms multiple arc-shaped grooves on the surface of the fixing block. Therefore, when the elastic block deforms, the arc-shaped grooves can both allow the elastic block to have space to deform and also play a limiting role, making it easier to use.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, through the design of fixed blocks, columns, and elastic blocks, achieves the basic structure of a crash barrier. The deformation of the elastic blocks enhances effective buffering, reducing the direct impact of impact forces on the bridge structure. It also increases the contact area between the crash barrier and the impacting object, helping to better disperse the impact force and thus extending the service life of the crash barrier. At the same time, the fitting design of the movable rod and the first and second insertion holes makes the installation and disassembly of the elastic blocks simple and convenient, reducing maintenance costs. Furthermore, the position and number of elastic blocks can be adjusted according to actual needs to adapt to different crash protection requirements. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A type of municipal bridge crash barrier, such as Figure 1-5As shown, the device includes a fixed block 1, which can be directly cast onto the top of the bridge. Several columns 2 are fixedly connected within the fixed block 1, and elastic blocks 3 are movably connected between adjacent columns 2. The fixed block 1, columns 2, and elastic blocks 3 form a crash barrier structure. Several slots 4 are provided on the surface of each elastic block 3, and a roller 5 is rotatably connected in each slot 4. Therefore, the roller 5 can increase the contact area between the impacting object and the crash barrier, thereby dispersing the impact force and further enhancing the crash barrier's anti-collision performance. At the same time, the fixed block 1 is composed of multiple arc-shaped plates, and the position of the elastic block 3 matches the arc-shaped grooves on the arc-shaped plates of the fixed block 1. Therefore, when the elastic block 3 deforms, the arc-shaped grooves can both allow the elastic block 3 to deform and also serve as a limiting function, which facilitates the increase of the safety of the device.

[0031] Subsequently, a sliding groove 8 is provided in each column 2, and a sliding rod 9 that matches the sliding groove 8 is slidably connected in each sliding groove 8. The sliding rod 9 is designed with an "L" shape, so that the sliding rod 9 can move in the sliding groove 8. A damping structure is provided between the sliding groove 8 and the sliding rod 9. Each sliding rod 9 and the corresponding sliding groove 8 are connected by a first spring 10. Therefore, after the driving force on the sliding rod 9 is removed, the sliding rod 9 can be driven to return to its original position by the first spring 10. The first spring 10 is provided with a damping structure to increase stability. Multiple sets of fixing grooves 11 are provided on the surface of each sliding rod 9. A movable rod 13 is rotatably connected in each fixing groove 11 through a rotating shaft 12. A coil spring 14 is provided at the connection between the rotating shaft 12 and the fixing groove 11 to withstand external force. After disappearing, the rotating shaft 12 and its surface structure can be restored to their original state. Multiple first insertion holes 15 that fit with the movable rod 13 are provided on the surface of the column 2. The first insertion hole 15 is set as a frustum structure, and the size of the first insertion hole 15 near the slide rod 9 is larger than the size of the other end. Multiple second insertion holes 16 that fit with the movable rod 13 are provided on the surface of the elastic block 3. Therefore, when the slide rod 9 moves downward, the movable rod 13 can be driven to rotate by the frustum structure of the first insertion hole 15 until it is disengaged from the second insertion hole 16, which facilitates the replacement of the elastic block 3. At the same time, when the slide rod 9 moves upward and returns to its original position, it is easy for the movable rod 13 to be reinserted into the second insertion hole 16, thereby limiting the elastic block 3 and fixing its position.

[0032] A fixed frame 17 is fixedly connected to the fixed block 1 on the side away from the elastic block 3. A movable plate 18, which slidably matches the fixed frame 17, is slidably connected inside the fixed frame 17. A damping structure is provided within both the movable plate 18 and the fixed frame 17, allowing the movable plate 18 to move within the fixed frame 17. The movable plate 18 and the fixed frame 17 are connected by a second spring 21. The second spring 21 also has a damping structure, so when the external force is small, it cannot compress the movable plate 18, thus preventing it from moving. The movement of the movable plate 18 is only possible after the external force on it disappears, due to the damping structure within the second spring 21. 1. The movable plate 18 is fixedly connected to both ends of the movable plate 18 with connecting rods 23. One end of each sliding rod 9 is fixedly connected to the surface of the connecting rod 23. Therefore, when the movable plate 18 moves, the sliding rod 9 can be moved synchronously through the connecting rod 23. The fixed frame 17 is provided with second limiting grooves 22 on both sides, and the sliding rod 9 slides in the second limiting grooves 22. The second limiting grooves 22 increase the stability of the movement of the sliding rod 9. This structure sets the fixed frame 17 on the side away from the elastic block 3, so that it is located on the rear side of the anti-collision wall, which can prevent other personnel from accidentally touching the device.

[0033] Therefore, when replacing the elastic block 3, the movable plate 18 can be stepped on to move it downwards, thereby squeezing the second spring 21. This, in turn, causes the sliding rod 9 to move downwards synchronously via the connecting rod 23. This causes the movable rod 13 to start rotating through the first insertion hole 15 until the movable rod 13 disengages from the second insertion hole 16. The elastic block 3 can then be removed from the top of the fixed block 1, facilitating its disassembly and replacement. After replacing the elastic block 3 and placing it between adjacent columns 2, the force applied to the movable plate 18 is released. The second spring 21 drives the movable plate 18 and the first spring 10 to reset the sliding rod 9, allowing the movable rod 13 to re-insert into the second insertion hole 16, thus fixing and limiting the elastic block 3. This structure makes the installation and disassembly of the elastic block 3 simple and convenient, reducing maintenance costs. Furthermore, the position and number of the elastic blocks 3 can be adjusted according to actual needs to adapt to different anti-collision requirements.

[0034] Furthermore, grooves 6 are provided at both ends of each elastic block 3, and protrusions 7 that fit into each groove 6 are slidably connected in each groove 6. Each protrusion 7 is fixedly connected to the surface of the corresponding column 2, which can increase the connection between the elastic block 3 and the column 2, making it less likely to detach from the surface of the column 2. This structure can quickly realize the installation and disassembly of the elastic block 3. Moreover, the protrusion 7 is set as a "T" shaped structure, which increases the stability and reliability of the connection and ensures that the anti-collision wall can maintain the integrity of the structure when it is impacted. At the same time, a first limiting groove 19 is provided on one side of the fixed frame 17. A limiting block 20 is slidably connected in the first limiting groove 19. A damping structure is provided at the connection between the first limiting groove 19 and the limiting block 20. The limiting block 20 is fixedly connected to one side of the movable plate 18, which can increase the stability of the movable plate 18 in the fixed frame 17. Therefore, it can increase the stability of the movement of the connecting rod 23 and the sliding rod 9.
