Description

Technical Field

[0001] The present invention relates to the technical field of pipe gallery vibration reduction, and more specifically, to a vibration reduction device for an industrial pipe gallery. Background Art

[0002] An industrial pipe gallery is an overhead structure or underground passage for laying various industrial pipelines in a centralized manner. It is widely used in the fields of petroleum, chemical industry, and electric power. It carries many important pipeline systems, such as pipelines for transporting oil, natural gas, steam and other media, and plays a vital role in the continuity and stability of industrial production. However, in actual operation, industrial pipe galleries are affected by various external factors, such as earthquakes, wind, machine vibration, etc. These factors may cause damage to the pipe gallery structure and leakage of pipelines, thereby causing serious safety accidents and economic losses.

[0003] However, in the prior art, the shock absorption of industrial pipe corridors mainly adopts some simple measures, such as increasing the flexibility of the pipes, setting shock-absorbing brackets, etc. Although the shock-absorbing device can effectively absorb and reduce mechanical vibration, it may produce excessive rebound force for vibrations with large amplitudes, and the existing shock-absorbing device will produce unnecessary vibrations during the shock absorption process, which will cause large-scale displacement of the pipes, thereby affecting the shock absorption effect and the stability of the pipe corridor structure.

[0004] In addition, the stiffness and damping characteristics of the existing shock absorbing devices are difficult to adjust according to the vibration amplitude. When the damping is too small, the insufficient damping still cannot prevent the pipeline corridor from offsetting a large distance, which eventually causes the pipeline corridor structure to be damaged. When the damping is too large, the vibration of the pipeline corridor cannot be well buffered, resulting in poor shock absorption effect of the pipeline corridor.

The energy storage member 31 is sleeved on the outside of the fourth elastic member 283, and combined with Figure 3 and Figure 6 As shown, the outer wall of the energy storage component 31 is provided with a first air inlet hole 311 and a first exhaust hole 312, and a one-way valve is arranged at the first air inlet hole 311. When the internal volume of the energy storage component 31 changes, gas can enter the energy storage component 31 through the first air inlet hole 311. The inner wall of the energy storage cavity 32 is provided with a second air inlet hole 321, and a one-way valve and an overflow valve are arranged at the second air inlet hole 321. Gas can enter the energy storage cavity 32 through the second air inlet hole 321.

The first exhaust hole 312 is connected to the second air inlet hole 321 through a ventilation pipe, wherein the energy storage component 31 is an elastic airbag.

[0040] See also Figure 1 As shown, the tunnel body 1 includes at least two columns 11, at least two cross arms 12 are symmetrically arranged between every two adjacent columns 11, and a plurality of brackets 13 are evenly arranged between every two cross arms 12. The columns 11, the cross arms 12 and the brackets 13 or the cross arms 12 and the brackets 13 cooperate to form a shock-absorbing frame, and the shock-absorbing part 2 is arranged inside the shock-absorbing frame. There are multiple tunnel bodies 1 and every two tunnel bodies 1 are connected by the brackets 13. There are at least four shock-absorbing blocks 21, and one end of each shock-absorbing block 21 away from the energy storage cavity 32 is respectively fixed to the frame of the shock-absorbing frame, and the inner wall of each connecting frame 282 is fixedly connected with a connecting column 284, and every two adjacent connecting columns 284 are connected by a connecting rod.

[0041] See also Figure 3 As shown, each damping block 21 has two first buffer cavities 22 and second buffer cavities 23 symmetrically distributed along the middle section of the damping block 21 , and has two slide grooves 24 and two ventilation grooves 27 symmetrically distributed along the middle section of the damping block 21 .

[0042] During use, when the pipe gallery vibrates, an offset occurs between the upright column 11 and the cross arm 12 or between the cross arm 12 and the bracket 13, so that the shock absorbing blocks 21 are close to each other, so that the connecting frame 282 drives the piston plate 28 to move in the cross-sectional direction of the shock absorbing block 21 in the first buffer chamber 22 through the piston rod 281, so that the fourth elastic member 283 is compressed to buffer the vibration of the pipe gallery. When the piston plate 28 moves, the liquid in the first buffer chamber 22 is squeezed to make the first sealing member 25 move in the slide groove 24, and at the same time, the first elastic member 241 is compressed, so that the liquid in the first buffer chamber 22 enters the second buffer chamber 23 and the first buffer chamber 22 through the first through hole 221. The liquid enters the second buffer chamber 23 and the first buffer chamber 22 through the first through hole 221. The damping force is generated at the same time, so that the shock absorbing block 21 further buffers the vibration of the pipe gallery. When the shock absorbing block 21 finishes buffering the vibration of the pipe gallery and enters the rebound stage, the fourth elastic member 283 is compressed at this time. The compression of the elastic member 283 caused by the vibration generates a rebound force, so that the piston plate 28 moves in the opposite direction in the first buffer chamber 22, so that negative pressure is generated in the first buffer chamber 22, so that the second sealing member 26 moves in the direction away from the cross section of the shock-absorbing block 21, and at the same time, the second elastic member 225 is compressed, so that the liquid inside the chamber where the second buffer chamber 23 is connected to the first buffer chamber 22 enters the first buffer chamber 22 through the second through hole 222. When the liquid enters the first buffer chamber 22 through the second through hole 222, a damping force is generated, thereby consuming the energy of the fourth elastic member 283 during rebound, so that the rebound amplitude of the fourth elastic member 283 is gradually reduced. The liquid flows inside the chamber where the first buffer chamber 22 and the second buffer chamber 23 are connected to the first buffer chamber 22, and a damping force opposite to the vibration direction and the rebound direction of the fourth elastic member 283 is generated, so that the vibration is quickly buffered and the rebound amplitude of the fourth elastic member 283 is gradually reduced, thereby reducing the redundant vibration of the fourth elastic member 283 caused by excessive rebound.

[0043] Example 2

[0044] In actual use, it was found that when the damping was too small, the insufficient damping still could not prevent the corridor from shifting a large distance, eventually causing damage to the corridor structure. When the damping was too large, the vibration of the corridor could not be well buffered, resulting in poor shock absorption effect of the corridor. Further improvements were made on the basis of the above embodiments.

[0045] On the basis of the above embodiment, when in use, when the connecting frame 282 moves toward the cross-sectional direction of the shock absorbing block 21, the energy storage member 31 is compressed, so that the internal volume of the energy storage member 31 is reduced, so that the internal gas of the energy storage member 31 enters the energy storage chamber 32 through the first exhaust hole 312, the ventilation pipe and the second air inlet hole 321. At the same time, when the liquid in the first buffer chamber 22 enters the second buffer chamber 23 connected to the first buffer chamber 22, the pressure ring 231 moves away from the shock absorbing block in the second buffer chamber 23 connected to the first buffer chamber 22. 21, so that the gas inside the chamber connected to the second buffer chamber 23 and the ventilation groove 27 is compressed, so that the pressure of the chamber is increased. When the vibration amplitude is small, the compression amount of the gas is small. Since the pressure of the chamber is less than the elastic force of the third elastic member 273, the sealing column 271 seals the second exhaust hole 322 of the energy storage chamber 32, and the energy storage chamber 32 is not connected to the slide groove 24. At this time, the first sealing member 25 is only subjected to the elastic force of the first elastic member 241, so that the first through hole 221 is opened to a greater extent, and the shock absorbing block 21 can quickly respond to the vibration. When the vibration amplitude is large, the pressure ring 231 moves a lot, so that the pressure of the chamber connecting the second buffer chamber 23 and the ventilation groove 27 is greater than the elastic force of the third elastic member 273. At this time, the sealing column 271 moves inside the ventilation groove 27 due to the pressure, so that the second exhaust hole 322 inside the energy storage chamber 32 is connected to the slide groove 24 through the pipeline, so that the pressure inside the slide groove 24 increases. At this time, the first sealing member 25 is simultaneously subjected to the elastic force of the first elastic member 241 and the pressure of the gas inside the energy storage chamber 32. By increasing the first sealing member 2 5 is subjected to pressure, thereby increasing the internal damping of the shock absorbing block 21, thereby increasing the supporting force of the shock absorbing block 21 on the pipe gallery. When the shock absorbing block 21 recovers, the internal volume of the energy storage component 31 increases, and the gas enters the energy storage component 31 through the first air inlet 311. By changing the damping of the shock absorbing block 21, when the vibration amplitude is small, the shock absorbing block 21 can quickly buffer the vibration to prevent the pipe gallery from causing stress concentration due to the vibration. When the vibration amplitude is large, the increase in the internal damping of the shock absorbing block 21 can provide sufficient supporting force to prevent the pipe gallery from causing a large displacement due to the vibration.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
