Description

Technical Field

[0001] The present invention relates to the technical field of dampers, and in particular to an inertia-friction composite damper. Background Art

[0002] With economic development and increased awareness of energy dissipation and vibration reduction technologies, more and more buildings are incorporating energy dissipation and vibration reduction components. Friction dampers, due to their simple construction and superior hysteretic performance, have become increasingly popular in building structural energy dissipation and vibration reduction designs in recent years. A damper is a device that provides resistance to motion and dissipates kinetic energy. Various dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, firearms, and the automotive industry to reduce vibration and energy. Since the 1970s, these technologies have been gradually applied to structural engineering projects such as buildings, bridges, and railways, resulting in rapid development. Patent CN 107816503 B discloses a friction damper. The friction damper comprises a housing having a longitudinal axis, a plunger capable of moving along the longitudinal axis, and a friction unit for generating friction on the plunger.

[0003] The structure of friction dampers currently on the market is relatively simple, and the inertia capacity structure is not effectively and reasonably applied. The inertia capacity element itself only has the functions of inertia adjustment and energy transfer. In order to more effectively achieve the purpose of shock (vibration) control, it is often necessary to connect the inertia capacity with mechanical elements such as springs and energy-consuming elements to work together. Therefore, there is room for optimization of the energy-consuming capacity of the existing friction damper structure. In addition, the initial friction damping of traditional friction dampers is mostly fixed and has no adjustment capability, and the piston rod on the damper does not have the ability to automatically clean and lubricate.

[0004] In order to solve the above problems, the present invention proposes an inertia-friction composite damper. Summary of the Invention

[0019] (3) Beneficial effects:

[0020] A. This composite damper has built-in friction damping components and inertia components. When the piston rod end mounting seat is subjected to external force vibration, the friction damping component provides resistance to the piston rod's movement, dissipating the motion energy. During this process, the inertia component amplifies the displacement acceleration, thereby improving the energy dissipation capacity of the friction damping structure.

[0022] C. The friction damping assembly and the piston rod linkage lubrication assembly are arranged in coordination. The centrifugal force generated by the movement of the first piston sucks the lubricating oil in the shell box through the suction pipe and the filter element. The lubricating oil is sucked into the end tube, so that the damper works with both viscous and squeeze oil film damping effects, thereby improving the damping effect. The reciprocating movement of the first piston will pump the lubricating oil in the shell box out through the pump pipe and input it into the annular liquid bag in the mounting ring. The annular liquid bag is filled with liquid and expands to come into contact with the telescopic piston rod. During the telescopic movement of the piston rod, the annular liquid bag plays a role in cleaning the surface of the piston rod. When the continuous pumping reaches the pressure relief valve threshold, the lubricating oil in the annular liquid bag is pumped out through the pressure relief valve, and the surface of the piston rod 3 is sprayed with lubricating oil, which plays a role in lubricating the piston rod on the damper.

[0043] In this embodiment, referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the piston rod linkage lubricating assembly 7 includes a liquid suction pipe 701 connected through the outer wall of one side of the middle part of the end cylinder 501, and one end of the liquid suction pipe 701 is connected through a filter element 704. The other side of the middle part of the end cylinder 501 is connected through a pump liquid pipe 702, and the end parts of the liquid suction pipe 701 and the pump liquid pipe 702 are both provided with a one-way valve 703.

During the use of the above-mentioned composite damper, the end part of the piston rod 3 will drive the connecting rod 504 and the first piston 502 to reciprocate in the end cylinder 501, and the centrifugal force generated by the movement of the first piston 502 will suck the lubricating oil in the shell box 1 through the liquid suction pipe 701 and the filter element 704. The lubricating oil is sucked into the end cylinder 501, so that the damper works while there are two damping effects of viscous and extrusion oil film, which improves the damping effect. The reciprocating movement of the first piston 502 will pump the lubricating oil in the shell box 1 through the pump liquid pipe 702 and input it into the annular liquid bag 706 in the mounting ring 705. The annular liquid bag 706 is in contact with the piston rod 3 during the expansion and expansion movement, and the annular liquid bag 706 plays a role in cleaning the surface of the piston rod 3 during the expansion and expansion movement of the piston rod 3. When the continuous pumping reaches the threshold value of the pressure relief valve 707, the lubricating oil in the annular liquid bag 706 is pumped out through the pressure relief valve 707, and the surface of the piston rod 3 is sprayed with lubricating oil, which plays a role in lubricating the piston rod 3 of the damper.

[0044] Furthermore, a spring clip 9 is fixed on the outer wall of the end of the suction tube 701, and a first magnetic block 10 is embedded in the outer wall of the end of the spring clip 9. A second magnetic block 11 is embedded in the outer wall of one side of the crankshaft 602.

When the first magnetic block 10 and the second magnetic block 11 above the crankshaft 602 rotate, they are misaligned, and the spring clip 9 will be reset.

[0046] The beneficial effects of the present invention are as follows: the composite damper has a built-in friction damping component 5 and an inertia capacity component 6. During the external force vibration of the mounting seat 4 at the end of the piston rod 3, the friction damping component 5 provides resistance to the movement of the piston rod 3, thereby consuming the movement energy. During the process, the inertia capacity component 6 amplifies the displacement acceleration, thereby improving the energy consumption capacity of the friction damping structure.

[0047] Furthermore, the setting of the friction damping component 5 provides motion damping for the piston rod 3 through the elastic force of the damping spring 503, which is used to absorb the inherent vibration energy of the vibration system. During use, the worker can drive the screw 507 to rotate by turning the handwheel 509. The rotation of the screw 507 in the screw hole 506 will drive the second piston 508 to move in the end tube 501 through transmission. The movement of the second piston 508 can press the damping spring 503 in the end tube 501, thereby realizing the adjustment of the initial length of the damping spring 503 in the end tube 501 and realizing simple adjustment of the friction damping of the damper.

[0048] Furthermore, the friction damping component 5 and the piston rod linkage lubrication component 7 are arranged in coordination, and the centrifugal force generated by the movement of the first piston 502 sucks the lubricating oil in the shell box 1 through the suction pipe 701 and the filter element 704, and the lubricating oil is sucked into the end tube 501, so that the damper works with both viscous and extrusion oil film damping effects, thereby improving the damping effect. The reciprocating movement of the first piston 502 will pump the lubricating oil in the shell box 1 out through the pump pipe 702 and input it into the annular liquid bag 706 in the mounting ring 705. The annular liquid bag 706 is filled with liquid and expands to come into contact with the telescopic piston rod 3. During the telescopic movement of the piston rod 3, the annular liquid bag 706 plays a role in cleaning the surface of the piston rod 3. When the continuous pumping reaches the threshold of the pressure relief valve 707, the lubricating oil in the annular liquid bag 706 is pumped out through the pressure relief valve 707, and the surface of the piston rod 3 is sprayed with lubricating oil, which plays a role in lubricating the piston rod 3 on the damper.

[0049] Working principle: When the present invention is in use, the inertia and friction composite damper is used. The housing 1 is installed by using bolts and expansion bolts through the mounting holes 14 on the side plate 13. The piston rod 3 end mounting seat 4 is externally mounted on the force-receiving vibration structure. During the installation process, an external hexagonal rod tool can be inserted into the internal hexagonal hole 8, and the second rotating shaft 607 is screwed together. The second rotating shaft 607 rotates and drives the first rotating shaft 601 on both sides to rotate through the second gear 608 and the first gear 606. Under the cooperation of the crankshaft 602 and the crank 603, the piston rod 3 is driven to be telescopically adjusted along the guide cylinder 2. The cam 508 is pressed against the piston rod 3 and the cam 509 is pressed against the piston rod 3. The cam 508 is pressed against the piston rod 3 and the cam 509 is pressed against the piston rod 3. The cam 508 is pressed against the piston rod 3 and the cam 509 is pressed against the piston rod 3. 6 rotates through the transmission to drive the second piston 508 to move in the end tube 501. The movement of the second piston 508 can press the damping spring 503 in the end tube 501, thereby adjusting the initial length of the damping spring 503 in the end tube 501 and realizing a simple adjustment of the friction damping of the damper. During the telescopic movement of the piston rod 3 along the guide tube 2, the crankshaft 602 is driven to swing back and forth through the connecting frame 604 and the connecting shaft 605 structure. Under the cooperation of the crankshaft 602 and the crank 603, the first rotating shaft 601 and the first gear 606 on both sides are driven to rotate. The first gear 606 on both sides is driven to rotate. The coordinated transmission between the crankshaft 602 and the second gear 608 drives the third rotating shaft 609 to rotate. The coordinated transmission between the third gear 610 and the second gear 608 drives the third rotating shaft 609 to rotate, thereby driving the fourth gear 611 at the bottom to rotate. The fourth gear 611 and the rack 613 coordinate transmission to drive the rack 613 and the friction plate 612 as the output end of the inertial displacement (acceleration) to move. The transmission ratio between the crankshaft 602 and the second gear 608 and the third gear 610 is set to ensure the amplification of the inertial displacement (acceleration), thereby improving the energy dissipation capacity of the friction damping structure.The centrifugal force generated by the movement of the first piston 502 sucks the lubricating oil in the shell box 1 through the suction pipe 701 and the filter element 704, and the lubricating oil is sucked into the end tube 501, so that the damper works with both viscosity and squeeze oil film damping, thereby improving the damping effect. The reciprocating movement of the first piston 502 will pump the lubricating oil in the shell box 1 out through the pump pipe 702 and input it into the annular liquid bag 706 in the mounting ring 705. The annular liquid bag 706 is filled with liquid and expands to contact the telescopic piston rod 3. During the telescopic movement of the piston rod 3, the annular liquid bag 706 plays a role in cleaning the surface of the piston rod 3. When the pressure relief valve 707 threshold is reached through continuous pumping, the pressure in the annular liquid bag 706 is increased. Lubricating oil is pumped out through the pressure relief valve 707 and sprayed onto the surface of the piston rod 3, thereby lubricating the piston rod 3 on the damper. During the rotation of the crankshaft 602, when the second magnetic block 11 above rotates to the same horizontal plane relative to the first magnetic block 10, the first and second magnetic blocks 10, 11, repel each other with the same polarity, causing the spring plate 9 to flip and strike the filter element 704. As the crankshaft 602 rotates, the first and second magnetic blocks 10, 11, become misaligned, causing the spring plate 9 to reset. As the crankshaft 602 continues to rotate, the spring plate 9 and first magnetic block 10 structure reciprocately strike the filter element 704, preventing clogging of the filter element 704 and facilitating the pumping of lubricating oil.

As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
