Description

Technical Field

[0001] This invention belongs to the field of bridge vibration reduction technology, specifically a shock-absorbing device and shock-absorbing method for bridge design. Background Technology

[0002] Bridges are susceptible to vibration during use and load-bearing. Therefore, when designing and constructing bridges, shock-absorbing devices are usually installed between the piers and the bridge to buffer and reduce the vibration forces experienced by the bridge.

[0003] For example, Chinese Patent CN217678555U discloses a shock-absorbing device for bridge design, comprising: a base plate, a main shock absorber, and a support plate. The main shock absorber is characterized by: a guide ring surrounding its free end; multiple horizontally arranged shock absorbers distributed along the inner circumference of the guide ring; the guide ring being rotatably connected to a left-side inclined support device and a right-side inclined support device; a first slider being fixedly mounted on each of the left-side and right-side inclined support devices; a second slider being rotatably connected to the other end of each of the left-side and right-side inclined support devices; and a balancing fixing device being provided on the left-side and right-side inclined support devices. This design effectively prevents the bridge deck from tilting and ensures that the force is evenly distributed on both sides.

[0004] Due to China's vast territory, there are large temperature differences between the north and south. In western my country, such as Xinjiang, which has a temperate continental climate, the temperature difference between day and night is large. Temperature changes affect the viscosity of the damping oil in the shock absorber. In low-temperature environments, the viscosity of the damping oil will increase, affecting its fluidity and causing the shock absorber to become stiff. In high-temperature environments, the viscosity of the damping oil will decrease, thus affecting the damping effect.

[0005] Therefore, it is necessary to propose a shock-absorbing device and shock-absorbing method for bridge design. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a shock-absorbing buffer device for bridge design, comprising a pier body, a shock absorber body, a housing box, a support platform, a separation mechanism, and an adjustment mechanism. The shock absorber body is a common hydraulic shock absorber. The housing box is detachably installed inside the pier body.

Through the cooperation of the partition frame and the support plate, the inner cavity of the housing is divided into two chambers. In addition, the shock absorber body is located in the inner cavity of the partition frame.

[0009] The adjustment mechanism includes a heat exchange rib plate and a heating tube. The heating tube is fixedly installed on the bottom surface of the support plate. The heating tube is a common resistance heating tube and is located in the inner cavity of the partition frame. The heating tube is used to heat the inside of the partition frame.

One end of the heat-conducting rib plate penetrates the bottom surface of the housing and is fixedly installed with a support plate that fits against the connecting plate. Silicon grease is evenly applied between the support plate and the connecting plate so that the heat-conducting rib plate can conduct heat energy into the pier body.

[0011] Preferably, an air pressure balancing valve is provided on the upper end face of the container body. The air pressure balancing valve is used to balance the air pressure in the inner cavity of the container body to improve the safety of use. A control pipe is fixedly connected to the outer wall of the support plate. The inner cavity of the container body is connected to an external water pump through the control pipe.

The control screw is connected to the cleaning plate through internal and external thread engagement. The control screw passes through the cleaning plate, and rotating the control screw can control the lifting and lowering of the cleaning plate, thereby scraping off the scale on the outer wall of the heat exchange fin plate and improving the heat exchange efficiency of the heat exchange fin plate.

[0015] Preferably, a transmission screw is rotatably mounted on the inner wall of the mounting block, and a cleaning brush for cleaning the heating tube is slidably mounted on the inner wall of the partition frame. The bristles on the outer wall of the cleaning brush wrap around the heating tube. The transmission screw passes through the cleaning brush and is connected to the cleaning brush through internal and external thread engagement. Rotating the transmission screw controls the raising and lowering of the cleaning brush, thereby cleaning the scale on the outer wall of the heating tube and improving heating efficiency.

[0016] Preferably, a control motor is fixedly installed on the outer wall of the mounting block. The control motor is a common waterproof motor. A drive gear is fixedly installed on the output end of the control motor. A control gear that meshes with the drive gear is fixedly installed on the outer wall of the control screw. A transmission gear that meshes with the drive gear is fixedly installed on the outer wall of the transmission screw.

The connecting frame can slide along the inner wall of the sealing plug. One end of the connecting frame is fixedly connected to the sealing plug, which is a common frustum-shaped rubber plug. A connecting spring for pressing the connecting frame is fixedly installed on the inner wall of the connecting pipe. The other end of the connecting spring is fixedly connected to the outer wall of the connecting frame. The connecting frame is pushed in real time by the elastic force of the connecting spring to separate the sealing plug from the connecting pipe, keeping the connecting pipe open. A control magnetic block for attracting the connecting frame is fixedly installed on the bottom surface of the cleaning plate. The connecting frame is made of common martensitic stainless steel that can be attracted by magnets.

[0021] A3. Install a support platform at the movable end of the shock absorber body to provide support for the bridge;

[0022] A4. When used in high-temperature environments, the combination of water injection and heat exchange ribs maintains the internal cavity of the housing at a suitable temperature, keeping the shock absorber body in a stable working state.

[0023] A5. When used in low-temperature environments, the water between the housing and the partition frame is drained, and the shock absorber body is heated by a water bath through a heating pipe to keep the shock absorber body in a stable working state.

[0024] A6. Clean the scale on the surface of the heat exchange fins and heating tubes by sliding the cleaning brush and cleaning plate to improve heat exchange efficiency;

[0025] A7. The sliding seal controls the flow of the connecting pipe, allowing water to be drained and replaced from the inner cavity of the container through the control pipe.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention divides the inner cavity of the housing into two chambers by setting a support plate and a partition frame. The shock absorber body is located in the inner cavity of the partition frame, and the heat exchange rib plate is located between the housing and the partition frame. The heating tube is a common resistance heating tube and is located in the inner cavity of the partition frame. In a high-temperature environment, the heat exchange rib plate introduces heat energy into the inner cavity of the concrete pier body, so that the shock absorber body is in a suitable working environment. In a low-temperature environment, the heating tube heats the shock absorber body, so that it is in a suitable working environment and can be used in a low-temperature environment, further improving the safety of use.

[0028] 2. This invention features a sliding cleaning plate and a cleaning brush. The bristles on the outer wall of the cleaning brush wrap around the heating tube. The outer wall of the cleaning plate is in contact with the outer wall of the heat exchange rib plate. By controlling the transmission screw and the control screw to rotate synchronously, the cleaning brush and cleaning plate are raised and lowered to remove scale from the outer wall of the heating tube and the heat exchange rib plate 11.

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1: As Figure 1-5 As shown in the embodiment of the present invention, a shock-absorbing buffer device for bridge design includes a pier body 1, a shock absorber body 13, a housing 6, a support platform 4, a separation mechanism, and an adjustment mechanism. The shock absorber body 13 is a common hydraulic shock absorber. The housing 6 is detachably installed inside the pier body 1. The inner wall of the pier body 1 has a housing chamber reserved for the housing 6 during the pouring process. One end of the shock absorber body 13 is fixedly installed on the inner wall of the housing 6, and the support platform 4 is fixedly installed on the other end of the shock absorber body 13, supporting the bridge deck through the support platform 4.

[0042] The partitioning mechanism includes a support plate 12 and a partition frame 16. The partition frame 16 is fixedly installed on the bottom surface of the support plate 12. The outer wall of the support plate 12 is fixedly connected to the inner wall of the housing 6. Through the cooperation of the partition frame 16 and the support plate 12, the inner cavity of the housing 6 is divided into two chambers. In addition, the shock absorber body 13 is located in the inner cavity of the partition frame 16.

[0043] The adjustment mechanism includes a heat exchange rib plate 11 and a heating tube 14. The heating tube 14 is fixedly installed on the bottom surface of the support plate 12. The heating tube 14 is a common resistance heating tube and is located in the inner cavity of the partition frame 16. The heating tube 14 is used to heat the inside of the partition frame 16. The heat exchange rib plate 11 is fixedly installed on the bottom surface of the accommodating box 6 and is located between the accommodating box 6 and the partition frame 16. The heat exchange rib plate 11 is a common copper plate with excellent thermal conductivity and is used to transfer the heat energy inside the accommodating box 6.

[0044] When put into use, clean water is injected into the cavity at the bottom of the bearing plate 12, so that the shock absorber body 13 is immersed in clean water. When used in high-temperature environments, the shock absorber body 13 is protected from direct sunlight by the pier body 1 and the housing 6. At the same time, the clean water cools the shock absorber body 13, and the heat exchange plate 11 introduces the heat energy into the inner cavity of the concrete pier body 1, so that the shock absorber body 13 is in a suitable working environment, adapts to high-temperature environments, and improves the safety of use.

[0045] When used in low-temperature environments, the water between the partition frame 16 and the housing 6 is drained, and the heat loss inside the partition frame 16 is reduced by the air between the partition frame 16 and the housing 6. At the same time, the heating tube 14 heats the body of the shock absorber 13, so that it is in a suitable working environment and can be used in low-temperature environments, thereby further improving the safety of use.

[0046] Preferably, a heat-conducting rib plate 10 is pre-embedded inside the pier body 1. A connecting plate 9 is fixedly connected to the top surface of the heat-conducting rib plate 10. One end of the heat-exchange rib plate 11 penetrates the bottom surface of the housing 6 and is fixedly installed with a support plate 8 that fits against the connecting plate 9. Silicone grease is evenly applied between the support plate 8 and the connecting plate 9 so that the heat-conducting rib plate 10 can conduct heat energy into the pier body 1.

[0047] Preferably, an air pressure balancing valve is provided on the upper end face of the container 6. The air pressure balancing valve is used to balance the air pressure in the inner cavity of the container 6 to improve the safety of use. A control pipe 7 is fixedly connected to the outer wall of the support plate 12. The inner cavity of the container 6 is connected to an external water pump through the control pipe 7. After the water pump is connected to the control pipe 7, clean water can be injected into and discharged into the inner cavity of the container 6.

[0048] Preferably, a control pump 15 is fixedly installed on the upper end face of the support plate 12. The control pump 15 is a common micro water pump, and its specific model can be selected according to actual usage requirements. The inner cavity of the partition frame 16 and the accommodating box 6 is connected through the control pump 15. Both the input end and the output end of the control pump 15 are provided with conduits.

[0049] Multiple control pumps 15 are provided, and at least two control pumps 15 have opposite drainage directions. By having multiple control pumps 15 work synchronously, the circulation of clean water inside and outside the partition frame 16 can be controlled to improve heat dissipation efficiency.

[0050] Example 2: Figure 6-8 As shown in Example 1, another embodiment of the present invention is as follows:

[0051] An mounting block 23 is fixedly installed on the upper end face of the bearing plate 12. A control screw 19 is rotatably installed on the inner wall of the mounting block 23. A cleaning plate 18 for cleaning the heat exchange rib plate 11 is slidably installed on the outer wall of the partition frame 16. The cleaning plate 18 is a common rubber plate. The outer wall of the cleaning plate 18 is in contact with the outer wall of the heat exchange rib plate 11. The control screw 19 is connected to the cleaning plate 18 through internal and external thread engagement. The control screw 19 passes through the cleaning plate 18. Rotating the control screw 19 can control the raising and lowering of the cleaning plate 18, thereby scraping off the scale on the outer wall of the heat exchange rib plate 11 and improving the heat exchange efficiency of the heat exchange rib plate 11.

[0052] Preferably, a transmission screw 20 is rotatably mounted on the inner wall of the mounting block 23, and a cleaning brush 21 for cleaning the heating tube 14 is slidably mounted on the inner wall of the partition frame 16. The bristles on the outer wall of the cleaning brush 21 wrap around the heating tube 14. The transmission screw 20 passes through the cleaning brush 21 and is connected to the cleaning brush 21 through internal and external thread engagement. Rotating the transmission screw 20 controls the raising and lowering of the cleaning brush 21, thereby cleaning the scale on the outer wall of the heating tube 14 and improving heating efficiency.

[0053] Preferably, a control motor 22 is fixedly installed on the outer wall of the mounting block 23. The control motor 22 is a common waterproof motor. A drive gear 25 is fixedly installed on the output end of the control motor 22. A control gear 24 that meshes with the drive gear 25 is fixedly installed on the outer wall of the control screw 19. A transmission gear 26 that meshes with the drive gear 25 is fixedly installed on the outer wall of the transmission screw 20. The control motor 22 drives the control gear 24 and the transmission gear 26 to rotate synchronously through the drive gear 25, thereby controlling the transmission screw 20 and the control screw 19 to rotate synchronously.

[0054] During use, scale needs to be cleaned regularly. At this time, the control motor 22 is started, and the transmission screw 20 and the control screw 19 are rotated synchronously, thereby controlling the lifting and lowering of the cleaning brush 21 and the cleaning plate 18 to remove scale from the outer wall of the heating tube 14 and the heat exchange rib plate 11.

[0055] Preferably, a connecting pipe 27 is fixedly installed on the outer wall of the partition frame 16, and a connecting frame 3 is slidably installed on the inner wall of the connecting pipe 27. The connecting frame 3 can slide along the inner wall of the sealing plug 5. One end of the connecting frame 3 is fixedly connected to the sealing plug 5, which is a common frustum-shaped rubber plug. A connecting spring 2 for pressing the connecting frame 3 is fixedly installed on the inner wall of the connecting pipe 27. The other end of the connecting spring 2 is fixedly connected to the outer wall of the connecting frame 3. The connecting frame 3 is pushed in real time by the elastic force of the connecting spring 2 to separate the sealing plug 5 from the connecting pipe 27, keeping the connecting pipe 27 open. A control magnetic block 17 for attracting the connecting frame 3 is fixedly installed on the bottom surface of the cleaning plate 18. The connecting frame 3 is made of common martensitic stainless steel that can be attracted by magnets.

[0056] The sliding cleaning plate 18 drives the control magnetic block 17 to approach the connecting frame 3. The magnetic force attracts the connecting frame 3 to slide, causing the sealing block 5 to seal the connecting pipe 27. At this time, the clean water outside the partition frame 16 can be discharged separately to keep it warm in a low-temperature environment.

[0061] A4. When used in high-temperature environments, the combination of water injection and heat exchange rib plate 11 maintains the internal cavity of the housing 6 at a suitable temperature and keeps the shock absorber body 13 in a stable working state.

[0062] A5. When used in a low-temperature environment, the water between the housing 6 and the partition frame 16 is drained, and the shock absorber body 13 is heated by the water bath through the heating pipe 14 to keep the shock absorber body 13 in a stable working state.

[0063] A6. The scale on the surface of the heat exchange fin plate 11 and heating tube 14 is cleaned by sliding the cleaning brush 21 and cleaning plate 18 to improve the heat exchange efficiency.

[0064] A7. The sliding seal 5 controls the connection of the connecting pipe 27, allowing water to be discharged and replaced inside the container 6 through the control pipe 7.
