Description

Technical Field

[0001] This utility model relates to the field of dampers, specifically an integrated iron-based alloy damper. Background Technology

[0002] Iron-based alloy dampers are devices that utilize the shape memory effect and superelastic properties of iron-based shape memory alloys to absorb and dissipate vibration energy. They can undergo phase transitions under temperature and stress, thereby realizing the shape memory effect, making them promising for applications in structural vibration control and damping.

[0003] Existing dampers can be referenced in the shape memory alloy self-resetting rubber damper with application number CN201621171312.X, which includes a pair of symmetrically distributed upper and lower main plates. A pair of upper and lower auxiliary plates are connected to the upper and lower main plates respectively, and the upper and lower auxiliary plates are interlocked. Two rubber plates are placed between the upper and lower auxiliary plates, and a super-elastic shape memory alloy wire is provided inside the upper auxiliary plate. A pair of cylinders are connected to the lower left and right sides of the upper main plate, and a pair of pistons fitted into the cylinders are connected to the upper left and right sides of the lower main plate. The pistons reciprocate within the cylinders. This utility model solves the problem of tilting and collapse of buildings or structures caused by dynamic responses to earthquakes or wind loads. Its structure is simple, easy to construct, economical, and practical. It can effectively reduce the dynamic response of structures and achieve self-resetting, thus achieving reinforcement and enhancing the resistance of civil engineering to dynamic loads such as earthquakes and strong wind loads. It also has strong energy dissipation capacity.

[0004] The aforementioned damper does not have a reset component during use, so it cannot effectively and quickly return to its original position after shock absorption and contraction to buffer the next vibration, resulting in drawbacks in the use of the device. Therefore, to address the above problem, an integrated iron-based alloy damper is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing dampers do not have a component for resetting during use. As a result, after shock absorption and contraction, they cannot effectively and quickly return to their original position to buffer the next vibration, which leads to drawbacks in the use of the device. This utility model proposes an integrated iron-based alloy damper.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the integrated iron-based alloy damper of this utility model includes a base; a top plate is provided above the base, and a rebound damping mechanism is provided between the base and the top plate;

[0007] The rebound damping mechanism includes a first friction rod, which is also disposed on the left and right sides of the top of the base. The bottom end of the first friction rod is fixedly connected to the base. A first friction sleeve is sleeved on the outer side of the top of the first friction rod, and the first friction rod is slidably connected to the first friction sleeve. A top plate is fixedly connected to the top of the first friction sleeve. Sliding grooves are also provided on the left and right sides of the first friction sleeve. A slider is fixedly connected to the left and right sides of the outer side of the first friction rod near the top. The other end of the slider is inserted into the sliding groove, and the slider is slidably connected to the sliding groove.

[0008] Preferably, the top end of the first friction rod is fixedly connected to the bottom end of the first return spring, the top end of the first return spring is fixedly connected to the inner top end of the first friction sleeve, and the outer sides of the first friction sleeve and the first friction rod are also fitted with a second return spring. The bottom end of the second return spring is fixedly connected to a base, and the top end of the second return spring is fixedly connected to a top plate.

[0009] Preferably, the front and rear ends of the bottom of the top plate are also fixedly connected to a first fixing seat. One end of a push rod is rotatably connected to the outside of the first fixing seat, and the other end of the push rod is rotatably connected to a second fixing seat. A first fixing block is fixedly connected to the bottom of the second fixing seat, and a second friction rod is fixedly connected to the bottom of the first fixing block.

[0013] The advantages of this utility model are:

[0014] 1. This utility model achieves a convenient reset function through the structural design of the rebound damping mechanism, which solves the problem that existing dampers do not have a reset component during use, so they cannot effectively return to their original position after damping and shrinking to buffer the next vibration, resulting in drawbacks in the use of the device. This invention improves the reset effect.

[0015] 2. This utility model, through the structural design of the rebound damping mechanism, achieves the function of preventing excessively fast rebound speed. It solves the problem that if the rebound speed is too fast during damping, the damping device is easily subjected to large rebound energy, thus failing to effectively dampen the shock. This improves the damping effect. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 As shown, an integrated iron-based alloy damper includes a base 1; a top plate 2 is provided above the base 1, and a rebound damping mechanism is provided between the base 1 and the top plate 2.

[0028] The rebound damping mechanism includes a first friction rod 10, which is also set on the left and right sides of the top of the base 1. The bottom of the first friction rod 10 is welded to the base 1. A first friction sleeve 11 is sleeved on the outer side of the top of the first friction rod 10. The first friction rod 10 is slidably connected to the first friction sleeve 11. The inner walls of the first friction rod 10 and the first friction sleeve 11 are both circular. The top of the first friction sleeve 11 is welded to the top of the top of the first friction sleeve 11. Slide grooves 12 are also opened on the left and right sides of the first friction rod 10. The left and right sides near the top of the outer side of the first friction rod 10 are also welded to one end of the slider 13. The other end of the slider 13 is inserted into the slide groove 12. The slider 13 is slidably connected to the slide groove 12. The slider 13 and the slide groove 12 are both square.

[0029] During operation, the top plate 2 moves downward. When the top plate 2 moves downward, it drives the first friction sleeves 11 on the left and right sides of the bottom end of the top plate 2 to move downward along the outside of the first friction rod 10 to perform friction and damping. At the same time, the sliding groove 12 opened on the side end of the first friction sleeve 11 moves along the outside of the slider 13.

[0030] Furthermore, the top end of the first friction rod 10 is welded together with the bottom end of the first return spring 14, the top end of the first return spring 14 is welded together with the inner top end of the first friction sleeve 11, the first friction sleeve 11 and the outer side of the first friction rod 10 are also fitted with a second return spring 15, the bottom end of the second return spring 15 is welded together with the base 1, and the top end of the second return spring 15 is welded together with the top plate 2.

[0031] During operation, as the first friction sleeve 11 moves downward along the outer side of the first friction rod 10, it simultaneously compresses the first return spring 14 and the second return spring 15 to retract.

[0032] Furthermore, the front and rear ends of the bottom of the top plate 2 are also welded together with a first fixed seat 16. One end of the push rod 17 is rotatably connected to the outside of the first fixed seat 16, and the other end of the push rod 17 is rotatably connected to a second fixed seat 18. The bottom end of the second fixed seat 18 is welded together with a first fixed block 19, and the bottom end of the first fixed block 19 is welded together with a second friction rod 22. The inner wall of the push rod 17 is designed to be circular.

[0033] During operation, the first fixed seats 16 at both ends of the bottom of the top plate 2 move downwards simultaneously, and the first fixed seats 16 drive one end of the push rod 17 to rotate along the outside of the first fixed seat 16. At the same time, the other end of the push rod 17 rotates along the outside of the second fixed seat 18, and the second fixed seat 18 drags the first fixed block 19 and the second friction rod 22 to move simultaneously.

[0034] Furthermore, the front and rear ends of the top of the base 1 are also welded together with a second fixing block 20. One end of the second fixing block 20 is welded together with a guide rod 21. A second friction rod 22 is sleeved on the outside of the guide rod 21, and the guide rod 21 is slidably connected to the second friction rod 22. The guide rod 21 is a circular rod design.

[0035] During operation, the second friction rod 22 moves along the outside of the guide rod 21 at one end of the second fixed block 20.

[0036] Furthermore, a third return spring 23 is sleeved on the outside of the guide rod 21. One end of the third return spring 23 is welded to a second fixing block 20, and the other end of the third return spring 23 is welded to a second friction rod 22.

[0037] During operation, the second friction rod 22 moves while simultaneously pulling the third return spring 23 to extend.

[0038] Furthermore, one end of the second friction rod 22 is inserted inside the second friction sleeve 24, and the second friction rod 22 is slidably connected to the second friction sleeve 24. The second friction rod 22 is slidably connected to the second friction sleeve 24, and the bottom end of the second friction sleeve 24 is welded together with a base 1. The inner wall of the second friction sleeve 24 is circular.

[0039] During operation, the outer side of the second friction rod 22 moves along the inside of the second friction sleeve 24 to perform friction damping again. After the damping ends, it automatically rebounds and returns to its original state under the action of the rebound force of the first return spring 14, the second return spring 15 and the third return spring 23.

[0040] Working principle: When subjected to downward pressure, the top plate 2 moves downward. As the top plate 2 moves downward, it causes the first friction sleeves 11 on both sides of the bottom of the top plate 2 to move downward along the outer side of the first friction rod 10, providing friction and damping. Simultaneously, the sliding grooves 12 on the side of the first friction sleeves 11 move along the outer side of the slider 13. As the first friction sleeves 11 move downward along the outer side of the first friction rod 10, they simultaneously compress the first return spring 14 and the second return spring 15, causing them to contract. At the same time, as the top plate 2 moves downward, it causes the first fixed seats 16 at both ends of the bottom of the top plate 2 to move downward simultaneously. The first fixed seats 16 also cause one end of the push rod 17 to move downward along the first... The outer side of the fixed seat 16 rotates, and at the same time, the other end of the push rod 17 rotates along the outer side of the second fixed seat 18. The second fixed seat 18 drags the first fixed block 19 and the second friction rod 22 to move simultaneously. When the second friction rod 22 moves, it moves along the outer side of the guide rod 21 at one end of the second fixed block 20. At the same time, the movement of the second friction rod 22 pulls the third return spring 23 to extend. At the same time, the outer side of the second friction rod 22 moves along the inside of the second friction sleeve 24, thereby performing friction damping again. After the damping ends, it automatically rebounds and returns to its original state under the action of the rebound force of the first return spring 14, the second return spring 15 and the third return spring 23.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
