Technical Field

[0001] This utility model relates to the field of bridge anti-collision technology, specifically an anti-collision structure for bridge piers. Background Technology

[0002] Bridge piers are the core load-bearing components that support the superstructure of bridges. They are widely used in various transportation projects such as highway bridges, railway bridges, and bridges spanning rivers and seas. Their main purpose is to safely transfer the load of the bridge superstructure (including vehicles, pedestrians, and the weight of the bridge deck) to the foundation, while resisting natural and human forces such as water flow, waves, and ship impacts.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technology makes bridge piers susceptible to impacts from ships and floating objects on the lake surface. These impacts can cause localized damage to the piers, affecting the stability of the bridge superstructure and threatening the safety of passing vehicles and pedestrians. Therefore, a collision-resistant structure for bridge piers is proposed to address these issues. Utility Model Content

[0027] Example 1

[0028] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides an anti-collision structure for a bridge pier, including a pier body 1 and a steel sleeve 2, wherein the steel sleeve 2 is fixedly connected to the surface of the pier body 1;

[0029] Anti-collision component 3 is installed on the top of steel sleeve 2;

[0030] The surface of the pier 1 is movably connected with a mating plate 4, and there are multiple mating plates 4. A rubber component 5 is movably connected to the side of the mating plate 4 away from the pier 1, and a positioning component 6 is provided on the top of the rubber component 5.

[0031] Specifically, when the pier 1 is hit, the anti-collision component 3 can reduce the impact force, and the positioning component 6 can facilitate the replacement of the rubber part 5.

[0032] Furthermore, when a floating object on the river surface hits the pier 1, the floating object will first hit the rubber component 5.

[0033] Example 2

[0034] The second embodiment of this utility model provides a bridge pier anti-collision structure. The anti-collision component 3 includes an inflatable ring 31, which is fixedly connected to the surface of the steel sleeve 2. A rubber ring 32 is fixedly connected to the surface of the inflatable ring 31. A matching groove 33 is opened on the side of the rubber ring 32 near the matching plate 4 to cooperate with the matching plate 4. The side of the matching plate 4 near the inner wall of the matching groove 33 is fixedly connected to the inner wall of the matching groove 33.

[0035] Specifically, by setting up the anti-collision component 3, when the pier is hit, the rubber component 5 will be impacted first, and then the mating plate 4 will apply the subsequent impact force to the rubber ring 32 and the air ring 31, while the steel sleeve 2 can prevent the surface of the pier 1 from cracking due to the impact force.

[0036] Furthermore, the rubber component 5 will move the mating plate 4 when subjected to impact, and the mating plate 4 will apply pressure to the air ring 31 and the rubber ring 32. At this time, the rubber ring 32 and the air ring 31 can reduce most of the impact force, and the final steel sleeve 2 can protect the surface of the pier 1.

[0037] Example 3

[0038] The third embodiment of this utility model provides an anti-collision structure for bridge piers. A positioning groove 7 is provided on the side of the mating plate 4 away from the pier body 1. A positioning plate 8 is movably connected to the inner cavity of the positioning groove 7. The side of the positioning plate 8 closest to the rubber component 5 is fixedly connected to the rubber component 5. A connecting hole 9 is provided at the top of the mating plate 4, and a chamfer 10 is provided at the top of the mating plate 4. The positioning assembly 6 includes a connecting shell 61. The bottom of the connecting shell 61 is fixedly connected to the rubber component 5, and a pull-out mechanism is movably connected to the inner cavity of the connecting shell 61. The top of the rod 62 passes through the connecting shell 61 and extends to the outside of the connecting shell 61. A spring 63 is sleeved on the surface of the rod 62. A control plate 64 is fixedly connected to the bottom of the rod 62. A moving hole 65 is opened on the side of the connecting shell 61 near the control plate 64. Both sides of the control plate 64 pass through the moving hole 65 and are fixedly connected to the limiting plate 11. A limiting groove 12 that cooperates with the limiting plate 11 is opened on the top of the mating plate 4. The limiting plate 11 is inserted into the inner cavity of the limiting groove 12.

[0039] Specifically, by setting a positioning groove 7, a positioning plate 8, a connecting hole 9, a chamfer 10, a positioning component 6, a limiting plate 11, and a limiting groove 12, after the rubber part 5 drives the positioning plate 8 to be inserted into the positioning groove 7, it can prevent the rubber part 5 from moving up and down. The connecting hole 9 can be connected to the connecting shell 61. The chamfer 10 can be squeezed with the limiting plate 11. After the limiting plate 11 is inserted into the limiting groove 12, the pressure of the spring 63 on the control plate 64 prevents the control plate 64 from driving the limiting plate 11 out of the limiting groove 12.

[0040] Furthermore, when it is necessary to install the rubber part 5 on the mating plate 4, hold the rubber part 5 to align the positioning plate 8 with the positioning groove 7, and then push the rubber part 5 to move the connecting rod into the connecting hole 9. At this time, the inclined surface on the limiting plate 11 will press against the chamfer 10 of the mating plate 4, which will cause the limiting plate 11 to rise. The rise of the limiting plate 11 will cause the control plate 64 to rise in the connecting shell 61. The movement of the control plate 64 will compress the spring 63. When the bottom of the limiting plate 11 is aligned with the limiting groove 12, the spring 63 will undergo elastic deformation to cause the control plate 64 to fall. The fall of the control plate 64 will cause the limiting plate 11 to be inserted into the limiting groove 12, which will fix the position of the rubber part 5.

[0041] Working principle:

[0042] When floating debris hits the pier 1, it first impacts the rubber component 5. The impact force on the rubber component 5 causes the mating plate 4 to move, which then applies pressure to the inflatable ring 31 and the rubber ring 32. At this point, the rubber ring 32 and the inflatable ring 31 can mitigate most of the impact force. Finally, the steel sleeve 2 protects the surface of the pier 1. When the rubber component 5 needs to be installed on the mating plate 4, holding the rubber component 5 aligns the positioning plate 8 with the positioning groove 7, and then pushing the rubber component 5 moves the connecting rod. When the device moves into the connecting hole 9, the inclined surface on the limiting plate 11 will press against the chamfer 10 of the mating plate 4, which will cause the limiting plate 11 to rise. The rise of the limiting plate 11 will cause the control plate 64 to rise within the connecting shell 61. The movement of the control plate 64 will compress the spring 63. When the bottom of the limiting plate 11 is aligned with the limiting groove 12, the spring 63 will undergo elastic deformation, causing the control plate 64 to descend. The descent of the control plate 64 will cause the limiting plate 11 to be inserted into the limiting groove 12, which will fix the position of the rubber part 5.

[0043] In summary, the anti-collision effect is achieved through the cooperation of the anti-collision component 3, the mating plate 4, the rubber part 5, the positioning component 6, the inflatable ring 31, the rubber ring 32, and the mating groove 33.
