Description

Technical Field

[0001] This invention belongs to the field of self-resetting damper technology, specifically relating to a sloped variable friction self-resetting damper. Background Technology

[0002] my country is a country prone to earthquakes. When earthquakes occur, the affected areas suffer not only heavy casualties but also severe damage to the social and economic order. To mitigate the impact of earthquakes and protect the safety of buildings and property, energy dissipation and vibration reduction dampers are needed. Dampers are currently the most widely used energy dissipation and vibration reduction technology. Installing dampers in new buildings or repairing damaged buildings after an earthquake extends the structure's natural period, increases the structural damping ratio, and dissipates seismic energy, thus achieving the effect of energy dissipation and vibration reduction.

[0003] In the field of disaster prevention and mitigation in civil engineering, the realization of restorable buildings mainly involves the use of dampers in seismic design of building structures and reinforcement of existing buildings. Insufficient energy dissipation capacity of building structures and excessive residual deformation after earthquakes are the main causes of structural collapse. Self-resetting components can reduce or even eliminate residual displacement after earthquakes, but their own energy dissipation capacity is somewhat insufficient and cannot effectively control peak displacement. Friction energy dissipation elements are currently common energy dissipation and damping devices, featuring low displacement and high energy dissipation characteristics, but they lack restoring capability.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

Detailed Implementation

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention.

For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0046] According to specific embodiments of the present invention, such as Figure 1-10As shown, this invention provides a self-resetting damper with inclined plane variable friction. The self-resetting damper includes an inclined plane sliding friction energy dissipation system. The inclined plane sliding friction energy dissipation system includes an inclined plane friction plate, a slider, a compression spring 12, and a compression spring cylinder 03. The inclined plane friction plate includes an upper friction plate 0101 and a lower friction plate 0102, and the slider includes an upper slider 0201 and a lower slider 0202. At least two inclined planes are provided in the upper friction plate 0101 and / or the lower friction plate 0102. When the two inclined planes are located on the same friction plate, the two inclined planes form a V-shape. One of the upper slider 0201 and the lower slider 0202 has a V-shaped surface that simultaneously contacts the two inclined planes. When the two inclined planes are located on the upper friction plate 0101 and the lower friction plate 0102 respectively, the upper friction plate 0101 and the lower friction plate 0102... The two inclined planes are parallel to each other; both the upper slider 0201 and the lower slider 0202 have an inclined plane with the same inclination angle as the corresponding inclined plane; the compression spring cylinder 03 is a hollow cylinder, and a part of the upper slider 0201 and the lower slider 0202 are located in the compression spring cylinder 03, so that the upper slider 0201 and the lower slider 0202 can slide along the hollow cylinder guide; a compression spring 12 is provided in the hollow cylinder inside the compression spring cylinder 03, and the compression spring 12 presses against the upper slider 0201 and the lower slider 0202; one end of the upper friction plate 0101 and the lower friction plate 0102 on the same side is fixedly connected to the first connecting member, and a cantilevered connecting part is provided on one side of the compression spring cylinder 03, and the compression spring cylinder 03 is connected to the second connecting member through the connecting part; the first connecting member and the second connecting member are used in the building structure.

[0047] The upper slider 0201 presses against the inclined surface of the upper friction plate 0101, and the lower slider 0202 presses against the inclined surface of the lower friction plate 0102. In other embodiments, one of the upper friction plate 0101 and the lower friction plate 0102 has a V-shaped inclined surface, and the other friction plate is a flat surface. The slider corresponding to the friction plate with the V-shaped inclined surface has a V-shaped surface, and the other slider is a flat surface. This arrangement makes the structure of the inclined sliding friction energy dissipation system simpler and easier to install and use.

[0048] Both the upper friction plate 0101 and the lower friction plate 0102 are provided with V-shaped surfaces, and the V-shaped surfaces on the upper friction plate 0101 and the lower friction plate 0102 are arranged opposite to each other; both the upper slider 0201 and the lower slider 0202 have V-shaped surfaces, the V-shaped surface of the upper slider 0201 is in contact with the V-shaped surface of the upper friction plate 0101, and the V-shaped surface of the lower slider 0202 is in contact with the V-shaped surface of the lower friction plate 0102.

[0049] When the second connecting end drives the compression spring cylinder 03 to move, the compression spring cylinder 03 drives the upper slider 0201 and the lower slider 0202 to slide relative to the friction plate. Since V-shaped surfaces are provided on both the upper and lower friction plates 0102, the upper slider 0201 and the lower slider 0202 have a larger relative displacement in the vertical direction, and thus the compression amount of the compression spring 12 is greater. Therefore, the normal force on the upper slider 0201 and the lower slider 0202 will also be greater, and the sliding friction force that the upper slider 0201 and the lower slider 0202 need to overcome when moving will also be greater. This makes the self-resetting damper have increasingly greater friction energy dissipation characteristics, thereby absorbing more building deformation energy.

[0050] In this embodiment, a boss is provided on the side of the V-shaped surface. The boss is used to stop the slider on the side and play a guiding role in the displacement movement of the slider, so that the slider always slides on the V-shaped surface.

[0051] The upper slider 0201 and the lower slider 0202 have the same structure. One end of the slider is a triangular prism with a V-shaped surface, which consists of two obtuse-angled sides of the triangular prism. The other side of the triangular prism is connected to one end of the cylindrical shape. The hollow cylinder of the compression spring cylinder 03 is a cylindrical through hole. A part of the cylindrical slider extends into the cylindrical through hole of the compression spring cylinder 03. The diameter of the cylindrical slider is the same as the inner diameter of the cylindrical through hole, so that the slider can be guided to slide up and down along the extension direction of the cylindrical through hole.

[0052] A left baffle 05 is connected to the left end of the upper friction plate 0101 and the lower friction plate 0102. The left baffle 05 forms the first connecting member. A cantilever end is provided in the middle of the left baffle 05. The cantilever end is used to connect with the building structure. A right baffle 04 is connected to the right end of the upper friction plate 0101 and the lower friction plate 0102. A planar transition part is provided between the V-shaped surface of the upper friction plate 0101 and the lower friction plate 0102 and the right baffle 04. The planes on the planar transition parts of the upper friction plate 0101 and the lower friction plate 0102 are parallel to each other and are perpendicular to the right baffle 04.

[0053] In this embodiment, the right side of the left baffle 05 is connected to the friction plate, and the left side of the left baffle 05 has a cantilever end, that is, the left baffle 05 is a T-shaped plate. The cantilever end on the left baffle 05 is connected to the baffle body by a rounded transition, which makes the left baffle 05 have better structural strength and facilitates the use of the left baffle 05 as a connector.

[0054] The left baffle 05 and the right baffle 04 are fixedly connected to the upper and lower friction plates 0102 by bolts and nuts. The bolts pass through the left baffle 05, the right baffle 04 and the upper friction plate 0101 or the lower friction plate 0102, and a fixing nut 11 is tightened on the protruding bolt thread.

[0055] This ensures that the left baffle 05, right baffle 04, and upper and lower friction plates 0102 are firmly fixed together, forming a rectangular frame.

[0056] The second connecting component is a motion guide rod 07, with a threaded section at the left end. The main body of the compression spring cylinder 03 is a hollow cylinder with an extended end in the middle. The extended end and the main body are connected by an arc transition. A threaded hole is provided on the extended end. The threaded section of the motion guide rod 07 is threaded into the threaded hole on the extended end of the compression spring cylinder 03. A clearance hole is provided in the middle of the right baffle 04, and the motion guide rod 07 passes through the clearance hole on the right baffle 04.

[0057] The self-resetting damper also includes a spring reset system, which includes a bolt stop 06, a reset spring 09, a spring guide rod 10, a left reset plate 13, and a right reset plate 08. A bolt stop 06 is provided at the point where the plane transition between the upper friction plate 0101 and the lower friction plate 0102 contacts the V-shaped surface. A spring guide rod 10 is provided between the bolt stop 06 and the right baffle 04, and the reset spring 09 is sleeved on the spring guide rod 10. The left reset plate 13 slides guided on the spring guide rod 10, and the left end of the reset spring 09 presses against the right end face of the left reset plate 13. The right reset plate 08 slides guided on the spring guide rod 10, and the right end of the reset spring 09 presses against the left end face of the right reset plate 08.

[0058] One end of the bolt stop 06 is a threaded part, and the other end is a square stop block. The threaded part is threaded into the friction plate. This design allows the bolt stop 06 to be more firmly fixed in the friction plate.

[0059] The spring guide rod 10 includes a guide part, a boss part, and a threaded part. The boss part is located between the guide part and the threaded part. The boss part is a radial boss on the spring guide rod 10. The outer diameter of the guide part and the threaded part are the same, and the outer diameter of the boss part is larger than the outer diameter of the guide part. The threaded part is threadedly connected to the right baffle 04. The left reset plate 13, the reset spring 09, and the right reset plate 08 are sequentially mounted on the guide part from left to right. The right end of the right reset plate 08 is in a stop fit with the left end face of the boss part.

[0060] In this embodiment, a spring guide rod 10 is provided between the bolt stop 06 on the upper friction plate 0101 and the lower friction plate 0102 and the left baffle 05, that is, two spring guide rods 10 are arranged side by side in the vertical direction, so that the reset plate is subjected to more uniform force.

[0061] On the bolt stop 06, a receiving hole is provided at the position corresponding to the spring guide rod 10. The guide part of the spring guide rod 10 can pass through the left reset plate 13 and extend into the receiving hole.

[0062] This ensures that the left end of the spring guide rod 10 is supported, preventing it from forming a cantilever structure and ensuring that the force on the spring guide rod 10 is more even. Under the pressure of the return spring 09, the left end face of the left return plate 13 abuts against the bolt stop 06; the right end face of the right return plate 08 abuts against the boss portion of the spring guide rod 10.

[0063] The left reset plate 13, the right reset plate 08 and the right baffle 04 are all provided with clearance holes in the middle, and the motion guide rod 07 extends out of the right baffle 04 through the clearance holes;

[0064] The motion guide rod 07 has a small diameter section and a large diameter section from left to right. A threaded section is provided on a part of the left end of the small diameter section. A stop nut is threaded on the threaded section. The stop nut is used to stop and cooperate with the left reset plate 13 so that when the motion guide rod 07 moves to the right, the stop nut drives the left reset plate 13 to move to the right to compress the reset spring 09.

[0065] A step is formed between the small diameter section and the large diameter section. The step is located on the right side of the right reset plate 08. The step is used to stop and cooperate with the right reset plate 08 so that when the motion guide rod 07 moves to the left, the step pushes the right baffle 04 to move to the left to compress the reset spring 09.

[0066] When in use, the cantilever end of the left baffle 05 and the rightmost end of the motion guide rod 07 of the self-resetting damper are connected to the nodes of the building as two connection ends. When the building shakes during an earthquake, the self-resetting damper can function as an energy-consuming building and reset itself.

[0067] Under the action of external force, when the motion guide rod 07 moves to the left, it pushes the compression spring cylinder 03 to move to the left. Both the upper and lower sliders 0202 slide to the left. Since the contact surface between the slider and the friction plate is an inclined plane, the upper slider 0201 moves downward along the inner cylinder of the compression spring cylinder 03, and the lower slider 0202 moves upward along the inner cylinder of the compression spring cylinder 03, causing the upper and lower sliders 0202 to undergo relative displacement at the same time. Consequently, the compression spring 12 is compressed, the normal force received by the upper and lower sliders 0202 increases, and the friction force that the slider needs to overcome to slide also increases further, allowing the self-resetting damper to absorb more energy. At the same time, the step on the motion guide rod 07 pushes the right reset plate 08 to move to the left, compressing the reset spring 09. When the compression spring cylinder 03 moves to the leftmost end, if the external force disappears, the slider will return to the middle position of the V-shaped inclined plane under the elastic force of the reset spring 09 and the action of the inclined plane on the friction plate, allowing the self-resetting damper to complete its reset.

[0068] When the motion guide rod 07 moves to the right, its frictional energy dissipation and reset principle are the same as when it moves to the left, and will not be repeated here.

[0069] In summary, the technical solution of the inclined plane variable friction self-resetting damper provided by this invention combines the use of a self-resetting component and an energy-dissipating element in parallel, enabling the damper to possess both self-resetting and high energy-dissipating characteristics. This inclined plane variable friction self-resetting damper of the present invention has a simple structure, is flexible in use, convenient in installation and positioning, and has good versatility, effectively meeting the needs of various building structure types. Furthermore, the materials used, such as compression springs, are readily available and inexpensive. Through structural design, it possesses excellent reset capability and damping shock absorption capability.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall be within the scope of protection of the pending claims of the present invention.
