Description

Technical Field

[0001] This invention relates to the field of structural vibration reduction and isolation technology, and in particular to a torsion tube energy dissipation device with high energy consumption. Background Technology

[0002] Metal energy dissipation devices, as passive control devices, belong to the displacement-related type. Under external vibration, the energy dissipation elements of metal energy dissipation devices enter the plastic yielding stage before structural damage, utilizing the yielding energy of the energy dissipation elements to reduce the vibration energy received by the structure itself. Torsional tube energy dissipation devices, as effective energy dissipation and vibration reduction devices, are mainly used in seismic and wind-resistant structural engineering. They primarily dissipate energy through the torsional yielding deformation of the metal tube, making them particularly suitable for coping with seismic forces and wind-induced vibrations.

[0003] Because the torsion tube in a torsion tube energy dissipation device experiences deformation in other directions, such as bending deformation, during vibration damping in addition to torsional energy dissipation, the failure rate of the energy dissipation component is accelerated. To ensure that the torsion tube undergoes only torsional deformation and not bending deformation as much as possible, thereby improving the energy dissipation and vibration damping effect, reliability, and service life of the component, existing solutions address the effects of other external forces on the torsion tube during vibration damping, achieving pure torsional energy dissipation. However, as an energy dissipation component, the magnitude of the torsion angle of the torsion tube directly reflects the amount of energy dissipated. Existing solutions convert the displacement caused by external forces into the torsion angle of the torsion tube. When the displacement is small, the corresponding torsion angle of the torsion tube is limited, failing to fully utilize the yield energy dissipation function of the torsion tube. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a torsion tube energy dissipation device with small displacement and high energy consumption.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows: A high-power torsion tube energy dissipation device includes a torsion force transmission component connected to the component to be damped, and a torsion tube assembly connected to the torsion force transmission component. It also includes a reverse energy dissipation component that provides a force opposite to that of the torsion force transmission component. The reverse energy dissipation component includes a force transmission connecting pipe fixedly connected to the torsion force transmission component, a force transmission gear fixedly connected to the inner wall of the force transmission connecting pipe, a planetary gear component meshing with the force transmission gear, and a crankshaft component radially slidably connected to the planetary gear component. The rotation axis of the crankshaft component coincides with the axis of the torsion tube assembly and is fixed to the end face of the torsion tube assembly away from the torsion force transmission component. The sliding connection portion of the crankshaft component rotates in the opposite direction to the planetary gear component when the planetary gear component rotates.

[0006] As a further improvement to the above technical solution: The planetary gear assembly includes relatively fixed planetary gears and a steering transmission frame. The steering transmission frame is provided with a closed slide groove arranged radially along the planetary gear assembly. The sliding connection part of the crankshaft assembly is a crankshaft mating shaft that slides with the closed slide groove. The sliding mating surfaces on both sides of the crankshaft mating shaft are in contact with the sliding surface of the closed slide groove. An energy-consuming movement space is left between the crankshaft mating shaft and the closed slide groove to provide reverse rotational displacement.

[0007] The sliding distance of the crankshaft mating shaft in the steering transmission frame and the rotation angle of the planetary gear assembly satisfy the following relationship: in, d This refers to the sliding distance of the crankshaft mating shaft within the steering transmission frame. This is the distance from the rotational axis of the crankshaft component to the center of the crankshaft mating shaft. This is the distance from the rotational axis of the crankshaft assembly to the rotational center of the planetary gear assembly. This represents the rotation angle of the planetary gear component.

[0008] The bottom of the crankshaft mating shaft is provided with a pointed cone structure to prevent the device from being damaged during the extreme vibration of the component to be damped. The energy dissipation movement space is the distance between the tip of the pointed cone structure and the closed slide groove. When the energy dissipation movement space is zero, the pointed cone structure contacts the steering force transmission frame and destroys the steering force transmission frame.

[0009] The crankshaft assembly further includes a reverse force transmission shaft, a support shaft, a force-bearing shaft, and two torsion transmission arms. The reverse force transmission shaft and the support shaft are located at the rotation axis of the crankshaft assembly. The crankshaft mating shaft is installed on the force-bearing shaft. The reverse force transmission shaft is installed on the torsion tube assembly and connected to one end of the force-bearing shaft through a corresponding torsion transmission arm. The other end of the force-bearing shaft is connected to the support shaft through a corresponding torsion transmission arm. The support shaft is rotatably mounted.

[0010] The torsion tube energy dissipation device also includes a rotating support base, on which the force transmission connecting pipe, the rotating shaft of the planetary gear component, and the supporting shaft are rotatably mounted.

[0011] The twist tube assembly includes a twist tube and a twist tube disc disposed at the end of the twist tube. The reverse force transmission shaft is a polygonal force transmission shaft, which is mounted on the twist tube disc.

[0012] When the torsional force transmission component is not under force, the meshing point of the planetary gear component and the force transmission gear, the center of the planetary gear component, the center of the sliding connection, and the rotation axis of the crankshaft component are all located in the same vertical plane.

[0013] The force transmission gear is arranged along the rotation direction of the torsional force transmission component. The center of the tooth of the force transmission gear is located at the top or bottom of the force transmission connecting pipe. When the torsional force transmission component is not under force, the meshing point between the planetary gear component and the force transmission gear is located at the center of the tooth of the force transmission gear.

[0014] The torsional force transmission component includes a movable force transmission arm and a support arm that are hinged to each other. The movable force transmission arm is hinged to the component to be damped, and the support arm is connected to the torsion tube assembly.

[0015] Compared with the prior art, the advantages of the present invention are as follows: This invention utilizes the meshing transmission of a force transmission gear and a planetary gear assembly to cause the planetary gear assembly to rotate in the same direction. This causes the sliding connection of the crankshaft assembly to slide radially along the planetary gear assembly. When the torsion transmission component is subjected to force in one direction and undergoes torsion, the sliding component of the crankshaft assembly slides radially along the force transmission gear via the force transmission gear and planetary gear assembly. At this time, the crankshaft assembly rotates around its rotation axis in the opposite direction to the torsion transmission component. This causes the torsion tube assembly to achieve opposite torsion on both sides when subjected to external force displacement. Compared to the existing method of fixing one end and torsion at the other, this invention achieves a significant increase in the torsion angle of the torsion tube assembly under the same external force displacement, thus achieving large-angle torsion of the torsion tube under small displacement. This significantly increases the torsional strain, thereby greatly improving the energy consumption power of the torsion tube and achieving excellent energy dissipation and vibration reduction effects. This results in a torsion tube energy dissipation device that achieves high energy consumption under small displacement. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of the present invention.

[0019] Figures 1 to 8 An embodiment of the high-power torsion tube energy dissipation device of the present invention is shown. The torsion tube energy dissipation device includes a torsion transmission element 1, a torsion tube assembly 2, and a reverse energy dissipation assembly 3. The torsion transmission element 1 is connected to the component to be damped, and the torsion tube assembly 2 is connected to the torsion transmission element 1 to convert the displacement generated by the external force into a torsion angle and transmit it to the torsion tube assembly 2, thereby achieving effective vibration damping and energy dissipation. In this embodiment, the reverse energy dissipation assembly 3 includes a force transmission connecting pipe 31, a force transmission gear 32, a planetary gear assembly 33, and a crankshaft assembly 34. The force transmission connecting pipe 31 is fixedly connected to the torsion transmission element 1, the force transmission gear 32 is fixedly connected to the inner wall of the force transmission connecting pipe 31, the planetary gear assembly 33 meshes with the force transmission gear 32, the planetary gear assembly 33 and the force transmission gear 32 rotate in the same direction, and the crankshaft assembly 34 is slidably connected along the radial direction of the planetary gear assembly 33.

[0020] Meanwhile, the rotation axis of the crankshaft component 34 coincides with the axis of the torsion tube assembly 2, and the crankshaft component 34 is fixed to the end face of the torsion tube assembly 2 away from the torsion transmission member 1; the sliding connection part of the crankshaft component 34 is offset from the rotation axis of the crankshaft component 34 and rotates in the opposite direction to the planetary gear component 33 when the planetary gear component 33 rotates, so as to provide a force opposite to the support arm 12 of the torsion transmission member 1, and its structure is simple and compact and occupies little space.

[0021] This invention utilizes the meshing transmission of the force transmission gear 32 and the planetary gear component 33 to cause the planetary gear component 33 to rotate in the same direction, driving the sliding connection of the crankshaft component 34 to slide radially along the planetary gear component 33. At this time, when the torsion transmission component 1 is subjected to force in one direction and torsion occurs, the sliding component of the crankshaft component 34 is driven to slide radially along the force transmission gear 32 through the force transmission gear 32 and the planetary gear component 33. At this time, the crankshaft component 34 rotates around its rotation axis in the opposite direction to the support arm 12, thereby driving the torsion tube assembly 2 to achieve reverse torsion on both sides when subjected to external force. Compared with the existing solution where one end is fixed and the other end is torsion, this invention achieves a multiple increase in the torsion angle of the torsion tube assembly 2 under the same external force displacement, thereby achieving a large-angle torsion of the torsion tube 21 under small displacement. At this time, the torsional strain is greatly increased, thereby significantly increasing the energy consumption power of the torsion tube 21, achieving excellent energy consumption and vibration reduction effects, and achieving the effect of small displacement and large energy consumption of the energy-consuming device.

[0022] Furthermore, the planetary gear assembly 33 includes relatively fixed planetary gears 331 and a steering force transmission frame 332. The steering force transmission frame 332 is provided with a closed groove 3321, which is arranged radially along the planetary gear assembly 33. The sliding connection part of the crankshaft assembly 34 is a crankshaft mating shaft 341 that slides in conjunction with the closed groove 3321. The sliding mating surfaces on both sides of the crankshaft mating shaft 341 contact and fit with the sliding surfaces of the closed groove 3321, allowing the crankshaft mating shaft 341 to effectively slide within the closed groove 3321 when the planetary gears 331 rotate. However, this restricts the rotational freedom between the crankshaft mating shaft 341 and the planetary gears 331, ensuring that the force exerted by the planetary gears 331 is effectively transmitted to the crankshaft mating shaft 341. An energy-dissipating movement space is provided between the crankshaft mating shaft 341 and the closed groove 3321 to provide sufficient reverse rotational displacement space.

[0023] After the planetary gear 331 rotates, the position of the steering transmission frame 332 shifts, which in turn causes the crankshaft mating shaft 341 to shift. Since the distance from the center of the crankshaft mating shaft 341 to the rotation axis of the crankshaft component 34 remains constant, the rotation of the planetary gear 331 forces the crankshaft mating shaft 341 to slide within the steering transmission frame 332 of the planetary gear 331, thus ensuring transmission and effectively driving the crankshaft component 34 to rotate in the opposite direction. In this embodiment, the crankshaft mating shaft 341 is a square crankshaft tube to better contact and fit with the sliding surface of the closed groove 3321.

[0024] like Figure 7 As shown, the sliding distance of the crankshaft mating shaft 341 in the steering force transmission frame 332 and the rotation angle of the planetary gear component 33 satisfy the following relationship: in, dThe sliding distance of the crankshaft mating shaft 341 in the steering force transmission frame 332. This is the distance from the rotation axis of the crankshaft assembly 34 to the center of the crankshaft mating shaft 341. The distance from the rotation axis of the crankshaft assembly 34 to the rotation center of the planetary gear assembly 33 is [distance missing]. This refers to the rotation angle of the planetary gear component 33.

[0025] Specifically, such as Figure 7 As shown, point A is the rotation center of planetary gear assembly 33, point B is the rotation center of crankshaft assembly 34, and point D is the initial position of the center point of crankshaft mating shaft 341. AD represents the distance from planetary gear assembly 33 to the center point of crankshaft mating shaft 341, which changes through slippage after crankshaft assembly 34 rotates. BD represents the distance from the center point of crankshaft mating shaft 341 to the rotation axis of crankshaft assembly 34 (the center points of the reverse force transmission shaft 342 and the support shaft 343), and this distance is a fixed value.

[0026] When subjected to external force, the rotation of the support arm 12 will eventually drive the crankshaft assembly 34 to rotate in the opposite direction. At this time, the center point D of the crankshaft mating shaft 341 shifts to point C. To satisfy the transmission relationship, AD The distance was ultimately offset due to the slippage of crankshaft mating shaft 341. C point, EC The distance is the distance that the crankshaft mating shaft 341 slides in the steering force transmission frame 332 of the planetary component after the planetary gear 331 rotates at an angle A. To simplify the calculation formula, let... AB=c, BC=a, AC=b, EC=d. A.B. C represents △ ABC The size of the three corners. a、c Given the number, after planetary gear 331 rotates by an angle A, according to the triangle sine theorem: We can conclude that: or As shown in the diagram, C Since it is an obtuse angle, therefore, take . ,Right now According to the Law of Sines, we can obtain: . AD=ca , AD=AE Therefore, we can conclude that: .

[0027] Preferably, such as Figure 3As shown, the bottom of the crankshaft mating shaft 341 is provided with a pointed cone structure 4, and the energy-dissipating movement space is the distance between the tip of the pointed cone structure 4 and the closed slide groove 3321. Within the energy-dissipating movement space, the crankshaft mating shaft 341 slides when the planetary gear 331 rotates. When the external force displacement is too large, causing the torsion tube 21 to rotate too large, that is, when the energy-dissipating movement space exceeds the preset range and the energy-dissipating movement space is zero, the pointed cone structure 4 contacts the steering force transmission frame 332 and destroys the steering force transmission frame 332, thereby disrupting the transmission relationship and protecting other parts from damage, so as to prevent the device from being damaged when the component to be damped experiences extreme vibration.

[0028] like Figure 6 As shown, the crankshaft assembly 34 also includes a reverse force transmission shaft 342, a support shaft 343, a force-bearing shaft 344, and two torsional force transmission arms 345. The reverse force transmission shaft 342 and the support shaft 343 are located at the rotation axis of the crankshaft component 34. The reverse force transmission shaft 342 is connected to the torsion tube assembly 2. The reverse force transmission shaft 342 and the torsion transmission arm 345, and the support shaft 343 and the torsion transmission arm 345 are fixedly connected. The torsion transmission arm 345 is hinged to the force-bearing shaft 344. The crankshaft mating shaft 341 is fixedly or hingedly installed in the middle of the force-bearing shaft 344. At this time, the reverse force transmission shaft 342 and the support shaft 343 are hinged to the two ends of the force-bearing shaft 344 through the corresponding torsion transmission arms 345. The force-bearing shaft 344 and the crankshaft mating shaft 341 can rotate relative to the reverse force transmission shaft 342 and the support shaft 343. While ensuring the effective sliding of the crankshaft mating shaft 341, the crankshaft component 34 is driven to rotate as a whole, and the force is transmitted to the torsion tube assembly 2, thereby providing a reliable and safe reverse energy-dissipating force to the torsion tube assembly 2. Its structure is simple and compact, and the transmission reliability is high.

[0029] In this embodiment, the torsion tube energy dissipation device further includes a rotating support base 5. The force transmission connecting pipe 31, the rotation axis of the planetary gear component 33, and the support shaft 343 are rotatably mounted on the rotating support base 5. When the support arm 12 rotates under the action of external force, the force transmission connecting pipe 31 rotates synchronously with the support arm 12, the planetary gear component 33 rotates in the same direction about the rotation axis of the planetary gear component 33, and the crankshaft component 34 rotates about the support shaft 343. The rotating support base 5 serves as a rotating support component, ensuring the safe and effective rotation of each component and guaranteeing the energy dissipation effect.

[0030] Preferably, a torsion tube support 6 is provided on the outer side of the force transmission connecting pipe 31. The force transmission connecting pipe 31 is rotatably mounted on the torsion tube support 6 to ensure effective support of the force transmission connecting pipe 31 while restricting other degrees of freedom of the force transmission connecting pipe 31 except for rotation. The force transmission connecting pipe 31 and the torsion tube support 6 can withstand the additional shear load when the torsion tube assembly 2 is torn, ensuring that the torsion tube assembly 2 only bears torsional deformation and does not produce bending deformation, thereby improving the buckling strength and fatigue life of the torsion tube assembly 2.

[0031] like Figure 1 As shown, the torsion tube assembly 2 includes a torsion tube 21 and a torsion tube disk 22 disposed at the end of the torsion tube 21. The reverse force transmission shaft 342 is a polygonal force transmission shaft, which is mounted on the torsion tube disk 22. The torsion tube 21 is fixedly connected to the support arm 12 on one axial side. When the support arm 12 generates a torsional force under the action of an external force, it causes the torsion tube 21 to undergo torsional deformation. The torsion tube 21 is fixedly connected to the torsion tube disk 22 on the other axial side. The torsion tube disk 22 is connected to the polygonal force transmission shaft through a force transmission hole. After the connection, the relative rotational freedom of the torsion tube disk 22 and the reverse force transmission shaft 342 is constrained, thereby ensuring that the torsional force is effectively transmitted to the end of the torsion tube 21.

[0032] Preferably, when the torsion transmission component 1 is not under force, the meshing point of the planetary gear component 33 and the transmission gear 32, the center of the planetary gear component 33, the center of the sliding connection, and the rotation axis of the crankshaft component 34 are all located in the same vertical plane. This ensures that the rotation angle of the crankshaft component 34 is the same in both positive and negative directions, avoiding the problem of inconsistent allowable lateral displacements on both sides of the moving transmission arm 11 when there is vibration displacement, thus ensuring that the torsion tube assembly 2 has the same energy dissipation capacity when rotating in both directions.

[0033] In this embodiment, the force transmission gear 32 is arranged along the rotation direction of the torsion transmission component 1. The center of the teeth of the force transmission gear 32 is located at the top or bottom of the force transmission connecting pipe 31. When the torsion transmission component 1 is not under force, the meshing point between the planetary gear component 33 and the force transmission gear 32 is located at the center of the teeth of the force transmission gear 32. The arc of the teeth of the force transmission gear 32 and the planetary gear tooth profile covers the angular torsion energy dissipation limit range of the torsion tube assembly 2, so as to ensure the effective energy dissipation of the torsion tube assembly 2 in the limit state and save gear processing costs. In this embodiment, the force transmission gear 32 has an internal gear ring that meshes with the planetary gear component 33 for transmission.

[0034] like Figure 8 As shown, the torsional force transmission component 1 includes a movable force transmission arm 11 and a support arm 12 that are hinged to each other. The movable force transmission arm 11 is hinged to the component to be damped via a support 13, and the support arm 12 is connected to the torsion tube assembly 2. The external component to be damped transmits vibration energy to the torsion tube assembly 2 sequentially through the movable force transmission arm 11 and the support arm 12, that is, the displacement generated by the external force is converted into a torsion angle and transmitted to the torsion tube assembly 2, thereby achieving effective vibration reduction and energy dissipation.

[0035] In this embodiment, when the vibration damping mechanism generates lateral vibration displacement, it drives the movable force transmission arm 11 to move. The displacement of the movable force transmission arm 11 causes the support arm 12 to rotate at an angle. Since the axial side of the torsion tube 21 is fixed to the support arm 12, the rotation of the support arm 12 will cause the torsion tube 21 to rotate at an angle. At the same time, since the force transmission connecting pipe 31 is fixed to the support arm 12, the rotation of the support arm 12 will also drive the force transmission connecting pipe 31 to rotate, and simultaneously drive the force transmission gear 32 fixed to the force transmission connecting pipe 31 to rotate. Due to the internal meshing of the force transmission gear 32 and the planetary gear 331, the rotation of the force transmission gear 32 causes the planetary gear 331 to rotate in the same direction. The rotation of the planetary gear 331 causes the crankshaft component 34 sleeved on the steering force transmission frame 332 to rotate. Based on the force direction analysis, the rotation direction generated by the crankshaft component 34 is opposite to that of the support arm 12. Therefore, the crankshaft component 34 and the support arm 12 will drive the axial sides of the torsion tube assembly 2 to rotate in opposite directions, thereby increasing the rotation angle of the torsion tube 21, increasing the energy consumption power, and achieving the effect of small displacement and large energy consumption of the torsion tube energy consumption device.

[0036] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
