Description

Technical Field

[0001] This invention relates to the field of bridge buffer equipment technology, and more specifically, to a highway bridge buffer for municipal bridge engineering. Background Technology

[0002] Resonance refers to the phenomenon where a physical system vibrates at a specific frequency with a larger amplitude than at other frequencies; these specific frequencies are called resonant frequencies. At resonant frequencies, even a small periodic vibration can produce a large vibration. Due to the kinetic energy stored in the system, when the vibration frequency of vehicles or people on a bridge causes the bridge to resonate, it can easily lead to violent vibrations and even bridge collapse.

[0003] Bridges are susceptible to damage due to resonance, which is detrimental to their long-term use. To reduce this resonance and extend the service life of bridges, highway bridge buffers are needed. Municipal bridges are mainly beam bridge structures, and existing bridge buffers only rely on springs for cushioning, resulting in poor cushioning effectiveness. Furthermore, when using traditional highway bridge buffers, the buffers bear the significant weight of vehicles and the bridge itself, which easily damages the buffer springs and the contact plates between the buffer and the bridge. Damaged buffers can no longer provide cushioning and require complete repair and replacement, followed by reinstallation, a time-consuming and labor-intensive process.

[0004] In view of this, we now propose a highway bridge buffer for municipal bridge engineering to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a highway bridge buffer for municipal bridge engineering, which has a simple structure and is easy to install, and can fully release the vibration and pressure of the bridge; the bottom buffer mechanism effectively consumes and releases vibration energy by connecting with the bridge column, thus avoiding damage to the bridge.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

The top buffer mechanism includes an upper fixed plate, on which multiple buffer through grooves are provided. A buffer groove is provided at the top of the bridge cap beam opposite to the buffer through groove, and a shock-absorbing column is installed in the buffer groove. A shock-absorbing cover is installed at the top of the shock-absorbing column.

[0008] Furthermore, in this invention, the aforementioned shock-absorbing column includes an upper shock-absorbing column and a lower shock-absorbing column. The top of the lower shock-absorbing column is provided with a shock-absorbing groove, and the upper shock-absorbing column is slidably connected to the shock-absorbing groove.

A transverse sliding groove is provided inside the transverse groove, and a resistance plate is slidably connected inside the transverse sliding groove. A buffer solution is provided inside the shock-absorbing groove, and a return spring is provided on the side of the resistance plate away from the shock-absorbing groove.

[0009] Furthermore, in this invention, the side of the aforementioned shock-absorbing groove is provided with a vertical sliding groove, and the side of the shock-absorbing upper column is fixedly provided with a sliding block, which is slidably connected to the vertical sliding groove; both the upper and lower sides of the sliding block are provided with sealing layers; and the bottom of the shock-absorbing upper column is provided with a sealing bottom layer.

[0010] Furthermore, in this invention, the aforementioned resistance plate is provided with liquid passage holes, and multiple transverse grooves are provided around the shock-absorbing grooves.

[0011] Furthermore, in this invention, multiple liquid passage holes are provided, and the liquid passage holes are arranged in a spiral shape; the number of spiral layers and the spiral radius of the multiple liquid passage holes are all different.

[0012] Furthermore, in this invention, a liquid filling pipe and a one-way valve are provided on the upper side of the aforementioned transverse groove. The liquid filling pipe is arranged in an inverted "S" shape, and one end of the liquid filling pipe is located at the bottom of the bridge cap beam. A sealing element is provided at the opening of the liquid filling pipe.

[0013] Furthermore, in this invention, the bottom buffer mechanism includes a support plate and a lower fixed plate, the connecting column is fixedly connected to the support plate, and the support plate and the lower fixed plate are connected.

[0014] Furthermore, in this invention, the lower fixing plate is provided with an annular recess, the support plate is annular and two arc-shaped auxiliary plates are fixedly provided on its inner side; the arc-shaped concave surfaces of the two arc-shaped auxiliary plates are arranged opposite each other, and connecting holes are provided on both sides of the arc-shaped auxiliary plates; connecting parts are provided at the connecting holes.

[0027] Example:

[0028] Please refer to Figure 1-6 , Figure 1 This is a front view of an embodiment of the present invention; Figure 2 This is a cross-sectional view of an embodiment of the present invention. For ease of observation, the bridge cap beam 1, the upper fixing plate 4, and the lower fixing plate 23 are shown in cross-section.

[0029] This application provides a highway bridge buffer for municipal bridge engineering, which includes a top buffer mechanism, a bottom buffer mechanism, and a bridge cap beam 1. The top buffer mechanism and the bottom buffer mechanism are respectively arranged on the upper and lower sides of the bridge cap beam 1. The bridge cap beam 1 is provided with a through groove 2, and a connecting column 3 is provided in the through groove 2. One end of the connecting column 3 is connected to the top buffer mechanism, and the other end is connected to the bottom buffer mechanism. The top buffer mechanism includes an upper fixing plate 4, and a plurality of buffer through grooves 5 are provided on the upper fixing plate 4. A buffer groove 6 is provided at the top of the bridge cap beam 1 opposite to the buffer through groove 5. A shock-absorbing column is provided in the buffer groove 6, and a shock-absorbing cover 7 is provided at the top of the shock-absorbing column.

[0030] Existing bridge dampers have simple structures, poor buffering effect, are prone to damage when bearing the heavy weight of vehicles and the bridge itself, and are difficult to inspect and repair, with time-consuming and labor-intensive repair and replacement processes. This invention, by setting up a top buffer mechanism and a bottom buffer mechanism connected by a connecting column 3, allows the vibrations and pressures received by the bridge and vehicles in the top buffer mechanism to be transmitted to the bottom buffer mechanism through the connecting column 3, enabling the vibrations and pressures to be fully released. The bottom buffer mechanism, connected to the bridge pillar, effectively dissipates and releases vibration energy, preventing bridge damage. It is understood that the shock-absorbing cover 7 is made of elastic material and can effectively buffer the vibrations. The shock-absorbing column can be selected to have its own energy-absorbing structure, effectively mitigating bridge vibrations and reducing the probability of resonance.

[0031] Furthermore, in this invention, the aforementioned shock-absorbing column includes an upper shock-absorbing column 8 and a lower shock-absorbing column 9. The top of the lower shock-absorbing column 9 is provided with a shock-absorbing groove 10, and the upper shock-absorbing column 8 is slidably connected to the shock-absorbing groove 10. The bottom of the shock-absorbing groove 10 is provided with a transverse groove 11. A transverse sliding groove is provided in the transverse groove 11, and a resistance plate 12 is slidably connected in the transverse sliding groove. A buffer solution is provided in the shock-absorbing groove 10, and a return spring 13 is provided on the side of the resistance plate 12 away from the shock-absorbing groove 10. The return spring 13 is connected to the bottom of the transverse groove 11. The upper damping column 8 and the lower damping column 9 are slidably connected through the damping groove 10. When the upper damping column 8 is subjected to vibration or pressure, it presses down through the buffer solution to push the resistance plate 12 to compress the return spring 13, thereby absorbing energy. At the same time, the buffer solution and the return spring 13 are made of different materials and have different resonant frequencies, which can effectively avoid the formation of resonance that could damage the bridge. There is also a certain resistance between the upper damping column 8 and the damping groove 10, which can effectively absorb energy and prevent the return spring 13 from being subjected to excessive pressure, thus shortening its service life.

[0032] Furthermore, in this invention, the side of the aforementioned shock-absorbing groove 10 is provided with a vertical sliding groove 14, and the side of the shock-absorbing upper column 8 is fixedly provided with a sliding block 15, which is slidably connected to the vertical sliding groove 14; both the upper and lower sides of the sliding block 15 are provided with sealing layers 16; and the bottom of the shock-absorbing upper column 8 is provided with a sealing bottom layer 17. The vertical sliding groove 14 and the sliding block 15 effectively limit the position of the shock-absorbing upper column 8, the sealing layer 16 effectively prevents the buffer solution from leaking out, and the sealing bottom layer 17 prevents the buffer solution from seeping into the shock-absorbing upper column 8. Furthermore, the sealing layer 16 is double-layered, and both outer sides of the double-layered sealing layer 16 are provided with inverted "T"-shaped protrusions; the protrusions of the double-layered sealing layer 16 deform and adhere tightly after being pressed against the vertical sliding groove 14, allowing for better sealing of the buffer solution.

[0033] Furthermore, in this invention, the resistance plate 12 is provided with a liquid passage hole 18, and multiple transverse grooves 11 are provided around the shock-absorbing groove 10. The liquid passage hole 18 provided on the resistance plate 12 facilitates the passage of buffer solution, further forming a buffer. Multiple transverse grooves 11 can effectively increase the buffering efficiency; at the same time, the return springs 13 inside the shock-absorbing grooves 10 surrounding the transverse grooves 11 can prevent each other from causing resonance.

[0034] Furthermore, in this invention, multiple liquid passage holes 18 are provided, and the liquid passage holes 18 are arranged in a spiral shape; the number of spiral layers and the spiral radius of the multiple liquid passage holes 18 are all different. The multiple spiral liquid passage holes 18 lengthen the passage path of the buffer solution, effectively increasing the energy absorption effect; at the same time, the different number of spiral layers and the different spiral radii of the multiple liquid passage holes 18 effectively avoid the formation of resonance.

[0035] Furthermore, in this invention, a liquid inlet pipe 19 and a one-way valve 20 are provided on the upper side of the aforementioned transverse groove 11. The liquid inlet pipe 19 is arranged in an inverted "S" shape, with one end of the liquid inlet pipe 19 located at the bottom of the bridge cap beam 1. A sealing element 21 is provided at the opening of the liquid inlet pipe 19. The one-way valve 20 prevents the buffer solution from flowing back out through the liquid inlet pipe 19 due to pressure. The inverted "S" shape of the liquid inlet pipe 19 effectively prevents liquid from flowing out of the pipe, and the sealing element 21 further seals and prevents leakage. It is understood that maintenance personnel can remove the sealing element 21 and add buffer solution to the buffer groove 6 through the liquid inlet pipe 19 to replenish the leakage lost after long-term use. The sealing element 21 is detachably connected to the opening of the liquid inlet pipe 19.

[0036] Furthermore, in this invention, the aforementioned bottom buffer mechanism includes a support plate 22 and a lower fixed plate 23, with the connecting column 3 fixedly connected to the support plate 22, and the support plate 22 and the lower fixed plate 23 connected. It is understood that the lower fixed plate 23 is fixedly connected to the bridge pier, and the connecting column 3 transmits the upper vibration to the support plate 22 and the lower fixed plate 23, whereby the vibration energy is dissipated through the bridge pier.

[0037] Furthermore, in this invention, the lower fixing plate 23 is provided with an annular recess 24, and the support plate 22 is annular with two arc-shaped auxiliary plates 25 fixedly disposed on its inner side; the arc-shaped concave surfaces of the two arc-shaped auxiliary plates 25 are arranged opposite each other, and connecting holes 27 are provided on both sides of the arc-shaped auxiliary plates 25; connecting members 26 are provided at the connecting holes 27. The two oppositely arranged arc-shaped auxiliary plates 25 are well connected to the annular recess 24 of the lower fixing plate 23 through the connecting holes 27 and the connecting members 26, so that the annular recess can limit the arc-shaped auxiliary plates 25; it is understood that the connecting members 26 can be set as bolts 28 and nuts, and the pressure between the arc-shaped auxiliary plates 25 and the lower fixing plate 23 can be adjusted through the connecting members 26, thereby controlling the structural strength and facilitating maintenance and repair adjustments.

[0038] In summary, embodiments of the present invention provide a highway bridge buffer for municipal bridge engineering, comprising a top buffer mechanism, a bottom buffer mechanism, and a bridge cap beam 1. The top and bottom buffer mechanisms are respectively disposed on the upper and lower sides of the bridge cap beam 1. The bridge cap beam 1 is provided with a through groove 2, and a connecting column 3 is disposed within the through groove 2. One end of the connecting column 3 is connected to the top buffer mechanism, and the other end is connected to the bottom buffer mechanism. The top buffer mechanism includes an upper fixing plate 4, on which multiple buffer through grooves 5 are provided. A buffer groove 6 is provided at the top of the bridge cap beam 1 opposite to the buffer through groove 5, and a shock-absorbing column is disposed within the buffer groove 6. A shock-absorbing cover 7 is disposed at the top of the shock-absorbing column. By setting up a top buffer mechanism and a bottom buffer mechanism and connecting them with the connecting column 3, the present invention allows the vibration and pressure received by the bridge and vehicles from the top buffer mechanism to be transmitted to the bottom buffer mechanism through the connecting column 3, so that the vibration and pressure can be fully released. The bottom buffer mechanism, by connecting with the bridge column, effectively consumes and releases vibration energy, preventing bridge damage.

Various modifications and variations can be made to the present invention by those skilled in the art.
