Description

Technical Field

[0001] This invention relates to the field of composite damper technology, specifically to an assembled metal composite damper. Background Technology

[0002] Composite dampers combine different types of dampers or different materials through special structural design. Utilizing different energy dissipation mechanisms, they can cope with various seismic forces, dissipating energy more thoroughly and better protecting the main structure from earthquake damage. Pipeline systems are widely used in thermal power plants, nuclear power plants, chemical plants, and shipbuilding. Vibration frequently occurs during operation. Due to the complexity of pipeline systems, it is difficult to eliminate vibration at its source. Long-term pipeline vibration can significantly shorten the service life of the pipeline system and its connecting equipment, and severe vibrations under specific operating conditions can directly lead to safety accidents. This is especially true for gas and oil pipeline systems, which are complex dynamic structures where vibration is a frequent cause of failure and damage. Based on the source of vibration, it can be categorized into several types, including mechanical vibration, fluid vibration, valve self-excited vibration, and earthquakes. Vibration caused by unstable fluid flow under pressure, such as pipeline vibration caused by gas flow, is the most common. Therefore, composite dampers need to be installed during pipeline laying.

[0003] Current dampers have a small adjustable range, which causes the pipeline to deviate significantly from the vibration amplitude when vibration occurs. This large deviation increases the risk of failure and damage to oil and gas pipeline systems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a prefabricated metal composite damper that can reduce the deviation of pipelines during vibration.

An adjusting pressure plate is welded to one end of the second composite spring. A first composite spring that cooperates with the second composite spring is welded to the top of the damper base plate. Adjusting screws that cooperate with the adjusting pressure plate are rotatably installed at the four corners of the top of the damper top plate.

[0009] Preferably, the top of the damper top plate has a rotating groove that cooperates with the adjusting screw. The rotating groove is threadedly connected to the adjusting pressure plate. The inner diameter of the first composite spring is larger than the outer diameter of the second composite spring. The outer walls of both the first and second composite springs are wrapped with vulcanized rubber material, giving the device good antistatic performance. At the same time, the dual vibration resistance of the first and second composite springs is utilized.

[0010] Preferably, the amplitude limiting component includes a fixed base plate installed on the top of the damper base plate and the bottom edge of the damper top plate. The fixed base plate has mounting screws on both sides of its top end. A turntable seat is rotatably installed in the middle of the top end of the fixed base plate. An adjusting screw sleeve is welded to the top of the turntable seat. A limit hook is provided on the inner side of the adjusting screw sleeve.

[0011] Preferably, one end of the travel restriction hook is provided with an external thread, the travel restriction hook is threadedly connected to the adjusting screw sleeve, the mounting screw is threadedly connected to both the damper base plate and the damper top plate, and the upper and lower travel restriction hooks are staggered together. The stability of the assembled damper base plate and damper top plate is achieved through the connection of the upper and lower travel restriction hooks.

[0013] Preferably, the front of the indicator scale is flush with the inner edge of the damper cover, and the load of this design can be displayed by aligning the bottom of the damper cover with the indicator scale.

[0014] Preferably, an alarm horn is installed on the lower front of the load warning indicator, and a wire is symmetrically connected to the upper outer wall of the alarm horn. One end of the wire is electrically connected to a conductive sheet. A battery holder is installed on the upper back of the load warning indicator, and a button battery is provided on the inner side of the battery holder.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a prefabricated metal composite damper, which has the following advantages:

[0019] 1. By setting an adjusting screw, adjusting pressure plate, compound spring two, and compound spring one, the vibration resistance of this design can be further improved through the combined action of compound spring one and compound spring two, since compound spring two is built into this design. The height of the adjusting pressure plate can also be changed according to the fluid density in the pipeline and the vibration force generated during the flow, and the degree of compression of the adjusting pressure plate can be further adjusted, thereby achieving a wider range of adjustment of the damping value of this design, so as to reduce the deviation of the pipeline during vibration.

[0020] 2. By setting a fixed base plate, a turntable base, an adjusting screw sleeve, and a travel restriction hook, the design is stabilized by interlocking the travel restriction hooks during installation. During the adjustment of the damping value, the dimensions of the two connected travel restriction hooks are adjusted by rotating the adjusting screw sleeve and the travel restriction hook through the threads, so as to meet the assembly requirements of the pipeline support and improve the overall stability of the design.

[0021] 3. By setting up a load warning indicator board, alarm horn, wire 1, and conductive sheet, and ensuring the damper cover is in contact with the load warning indicator board, the load value of this design can be understood by reading the numerical value through the indicator scale. When the load is excessive, the bottom end of the damper cover will generate a thrust on the conductive sheet, causing the conductive sheet to elastically deflect around wire 1. By using the contact between the two conductive sheets, the alarm horn and the button battery form a closed circuit, and the alarm horn will emit an alarm sound to provide an overload alarm, so that maintenance personnel can adjust the gas flow rate in the pipeline to avoid excessive vibration and damage to the pipeline.

[0036] Please see Figure 1-8 This invention provides a technical solution for a prefabricated metal composite damper:

[0037] Example 1:

[0038] according to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an assembled metal composite damper includes a damper base plate 1 and a damper top plate 11 that is assembled with the damper base plate 1. Damper covers 12 are installed on both sides of the bottom end of the damper top plate 11. Deviation amplitude adjustment components 4 are installed at the four corners of the top of the damper base plate 1. Amplitude limiting components 3 are installed in the middle of the four edges of the top of the damper base plate 1. A load warning prompt component 2 is installed at one edge of the top of the damper base plate 1.

[0039] The deviation amplitude adjustment component 4 includes boss seats 42 installed at the four corners of the top of the damper base plate 1, and a composite spring 2 43 is installed at the bottom of the boss seat 42. An adjusting pressure plate 44 is welded to one end of the composite spring 2 43. A composite spring 1 41 that cooperates with the composite spring 2 43 is welded to the top of the damper base plate 1. Adjusting screws 45 that cooperate with the adjusting pressure plate 44 are rotatably installed at the four corners of the top of the damper top plate 11. A rotating groove 46 that cooperates with the adjusting screw 45 is opened at the top of the damper top plate 11. The rotating groove 46 is threadedly connected to the adjusting pressure plate 44. The inner diameter of the composite spring 1 41 is larger than the outer diameter of the composite spring 2 43. The outer walls of the composite spring 2 43 and the composite spring 1 41 are covered with vulcanized rubber material, which gives the device good antistatic performance. At the same time, by utilizing the dual anti-vibration performance of the composite spring 1 41 and the composite spring 2 43, the vibration resistance performance of this design can be effectively improved.

[0040] Example 2:

[0041] Based on Example 1, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the amplitude limiting component 3 includes a fixed base plate 31 installed on the top of the damper base plate 1 and the bottom edge of the damper top plate 11. Mounting screws 32 are provided on both sides of the top of the fixed base plate 31. A turntable seat 33 is rotatably mounted on the center of the top of the fixed base plate 31. An adjusting screw sleeve 34 is welded to the top of the turntable seat 33. A travel restriction hook 35 is provided on the inner side of the adjusting screw sleeve 34. One end of the travel restriction hook 35 is provided with an external thread 36. The travel restriction hook 35 is threadedly connected to the adjusting screw sleeve 34. The mounting screws 32 are threadedly connected to both the damper base plate 1 and the damper top plate 11. Two limiting hooks 35 are staggered and connected. The connection of the upper and lower limiting hooks 35 achieves the stability of the assembled damper base plate 1 and damper top plate 11. The initial compression degree of the damper top plate 11 and damper base plate 1 can be adjusted by adjusting the depth of the limiting hooks 35 screwed into the adjusting sleeves 34. A cylinder 51 is installed at the top center of the damper base plate 1. An inner steel frame 53 is installed on the inner side of the bottom center of the damper top plate 11. A sealing sleeve 52 is installed on the outer side of the bottom center of the damper top plate 11. The sealing sleeve 52 slides with the cylinder 51.

[0042] Example 3:

[0043] Based on Example 2, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the load warning indicator 2 includes a load warning indicator plate 21 installed at one edge of the top of the damper base plate 1. An indicator scale 22 is provided on one side of the load warning indicator plate 21. The front of the indicator scale 22 is flush with the inner edge of the damper cover 12. Alignment of the bottom end of the damper cover 12 with the indicator scale 22 displays the load of this design and also allows for calibration of the design's levelness. An alarm horn 23 is installed below the front of the load warning indicator 2. A first wire 24 is symmetrically connected to the upper part of the wall. One end of the first wire 24 is electrically connected to a conductive sheet 25. A battery holder 26 is installed on the back of the load warning indicator board 21. A button battery 28 is provided on the inner side of the battery holder 26. A second wire 27 is symmetrically connected to the lower part of the outer wall of the battery holder 26. The second wire 27 is electrically connected to the alarm horn 23. The conductive sheet 25 has an arc-shaped structure and is an elastic conductive copper sheet. Under the overload condition of this design, the two conductive sheets 25 will make contact, and an alarm will be triggered by the alarm horn 23.

[0044] In practical application, this prefabricated metal composite damper is installed at the vibration-resistant support of a pipeline. Because it incorporates a second composite spring 43, the combined action of the first composite spring 41 and the second composite spring 43 further enhances its vibration resistance. The damping performance can be adjusted according to the fluid density and the vibration force generated during flow. By rotating the adjusting screw 45 with a screwdriver, the adjusting screw 45 rotates with the threaded adjustment plate 44. Since the stiffness coefficient of the first composite spring 41 is greater than that of the second composite spring 43, rotating the adjusting screw 45 changes the height of the adjustment plate 44, allowing for further adjustment of its compression degree.

[0045] During installation, the interlocking of the traffic restriction hooks 35 ensures stability. Adjusting the damping value involves rotating the adjusting sleeve 34 along the threaded connection between the two hooks 35, thus adjusting the overall dimensions of the combined hooks.

[0046] As the gas flows through the pipe, the vibration will compress the composite spring 43 and the composite spring 41, causing the damper top plate 11 and the damper bottom plate 1 to come close together. The damper cover 12 is attached to the load warning plate 21, and the value can be read by the indicator scale 22 to understand the upper load value of this design. When the load is excessive, the damper cover 12 will move further down. The bottom end of the damper cover 12 will push the conductive plate 25. The conductive plate 25 will deflect around the wire 24, and the two conductive plates 25 will come close together. When the load reaches a certain value, the two conductive plates 25 will contact each other, and the alarm horn 23 and the button battery 28 will form a closed circuit, and the alarm horn 23 will emit an alarm sound.

[0047] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
