Description

Technical Field

[0001] This invention belongs to the field of bridge suspension rod vibration reduction technology, specifically a vibration damper. Background Technology

[0002] Hangers are widely used in long-span arch bridges and steel truss arch bridges. As a large-volume structure, cylindrical hangers are prone to wind-induced vibration under the action of wind on the bridge deck. Controlling their wind-induced vibration can reduce the damage to bridge components and ensure the safety of the overall bridge structure. Currently, wind-resistant dampers are usually installed on hangers, which can suppress the vibration of hangers under the action of external wind force. In the prior art, a wind-resistant and vibration-damping device for bridge suspenders, disclosed in CN113026533B, utilizes wind power to drive the wind-receiving plate to rotate. Simultaneously, the continuous deflection and impact of the wind-receiving plate pushes the stop bar and rotates along a circular block. The interaction of the guide rod and transmission rod converts this into axial motion, and a structure similar to a viscous damper counteracts wind force, thus consuming wind power and providing wind-resistant vibration. However, during this process, the wind-receiving plate, rotating under wind force, needs to impact the stop bar, generating vibration that is transmitted to the guide rod. Furthermore, the continuous impact of the wind-receiving plate leads to excessive wear and tear, requiring frequent replacement. Additionally, the viscous damper-like structure requires the energy-consuming rod to be internally sealed. However, since the energy-consuming rod is constantly exposed to the outside, it is easily corroded and damaged, breaking the internal seal and causing oil leakage. This results in high maintenance and replacement costs. Therefore, a vibration damper is proposed to solve these problems. Summary of the Invention

[0003] To address the problems mentioned in the background section, the present invention provides a shock absorber.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a shock absorber, comprising a rod body, a support assembly, a conversion mechanism, and two energy dissipation mechanisms; The support assembly is fixedly sleeved on the rod body, the conversion mechanism is disposed on the support assembly, and the two energy-consuming mechanisms are respectively disposed above and below the support assembly and connected to the conversion mechanism; The support assembly includes a mounting sleeve, which is fixedly fitted onto the rod body, and a waterproof top is fixedly fitted on the upper part of the mounting sleeve. The conversion mechanism includes a high-performance rubber sleeve, which is fixedly fitted onto the mounting sleeve. A fixed sleeve is fixedly fitted on the outside of the high-performance rubber sleeve. Limiting grooves are formed on both sides of the fixed sleeve.

Slider blocks that are slidably installed inside the limiting grooves are connected to both sides of the inner wall of the movable sleeve. A bearing sleeve is fixedly fitted on the outside of the movable sleeve. A rotating block is movably installed on the outside of the bearing sleeve. Several blades arranged in a circle are connected to the outside of the rotating block. The blades are arranged along the tangent of the rotating block. The energy-consuming mechanism includes a high-performance rubber sleeve II, which is fixedly fitted onto the mounting sleeve. A fixing seat I is fixedly fitted onto the lower outer side of the high-performance rubber sleeve II, and a fixing seat II is fixedly fitted onto the upper outer side of the high-performance rubber sleeve II. A sliding track can be formed between the fixing seat I and the fixing seat II. A damping component is fitted between the fixing seat I and the fixing seat II. A fixing plate is connected to the outer side of the damping component. One side of the fixing plate is connected to a rotating block. A waterproof sleeve that covers the fixing seat II and the fixing seat I is fixedly fitted onto the outer side of the fixing plate. The waterproof sleeve is located inside the waterproof top.

[0005] Preferably, a fixing ring is fixedly sleeved on the lower part of the outer side of the fixing sleeve, and a connecting ring is movably sleeved on the outer side of the fixing sleeve between the movable sleeve and the fixing ring. Sliding pieces located inside the limiting groove are connected to both sides of the inner wall of the connecting ring, and a buffer cotton that can abut against the lower part of the movable sleeve and the bearing sleeve is connected to the top of the connecting ring.

[0006] Preferably, a spring is fitted on the outer side of the fixing sleeve, one end of the spring is connected to the connecting ring, and the other end of the spring is connected to the fixing ring.

[0007] Preferably, each of the fixed sleeves has movable grooves located on both sides of the limiting groove. A locking block is slidably installed on the lower part of the movable groove. The inner side of the locking block extends into the interior of the limiting groove and abuts against the top of the slide plate. A second spring is connected to the outer side of the locking block, and the other end of the second spring is connected to the movable groove.

[0008] Preferably, a trapezoidal block is slidably installed on the upper left and right side of the interior of the movable groove, and a spring three is connected to the outer side of the trapezoidal block, with the other end of the spring three connected to the movable groove.

[0009] Preferably, the bottom of the trapezoidal block is connected to a connecting plate located inside the movable groove, the other side of the connecting plate is connected to a locking block, and an inclined block that can abut against the trapezoidal block is movably sleeved above the movable groove. A top rod is connected to the bottom of the inclined block, and the bottom end of the top rod passes through the fixed sleeve and extends into the interior of the limiting groove.

[0010] Preferably, the fixing seat one includes a toothed sleeve one, which is fixedly sleeved below the outer surface of the high-performance rubber sleeve two, and damping blocks one arranged in a row are installed on the inclined surface on the right side of the teeth of the toothed sleeve one.

[0011] Preferably, the second fixing seat includes a toothed sleeve, which is fixedly sleeved above the outer surface of the high-performance rubber sleeve. A damping block two is installed on the inclined surface on the left side of the tooth of the toothed sleeve, and the damping block two faces the damping block one.

[0012] Preferably, the damping assembly includes a movable block connected to a fixed plate. A plurality of rubber blocks are connected to a set of corresponding sides of the movable block. The rubber blocks are hollow and deformable. The rubber blocks can be engaged between damping blocks one and damping blocks two. Another set of corresponding sides of the movable block is connected to a rubber sheet.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a fixed base one, a fixed base two, and a damping component, allows the blades and rotating block to deflect along the bearing sleeve in a windy environment. Simultaneously, the rotating block, fixed plate, and damping component are subjected to the rotational force of the blades, causing the bearing sleeve to rise along the groove between fixed base one and fixed base two. This, in turn, drives the blades, rotating block, bearing sleeve, movable sleeve, and slider to rise along the interior of the limiting groove. During this rise, the rubber sheet generates friction with the inclined surface of the toothed sleeve one, and also creates resistance due to the weight of the blades, rotating block, bearing sleeve, and movable sleeve themselves. This achieves a wind damping effect, thus consuming some wind energy. As the blade rotates and rises, and the damping assembly descends between fixed base one and fixed base two, the rubber block rubs against damping block one and damping block two. Through the deformation and reciprocating process of the rubber block moving on damping block one and damping block two, the friction force of the blade and rotating block during descent can be increased, thereby achieving resistance to the rotation and descent of the blade and rotating block. It also produces the same damping effect as the rise during descent. Under the action of wind, this design realizes the up-and-down reciprocating motion of the blade rotation. This motion mode can replace the viscous damper used in wind-resistant shock absorbers and does not require the restriction of a sealed environment, making it suitable for use in exposed environments.

[0014] 2. This invention, by setting up a spring and a connecting ring, allows the damping component to rise to the highest point of the toothed sleeve when the spring returns to its original force and the buffer cotton abuts against the bearing sleeve. As the blade continues to rotate, the damping component descends between the fixed seat and the fixed seat. Due to the support force of the connecting ring and the sliding plate on the movable sleeve and the slider, most of the downward gravity of the blade, rotating block, bearing sleeve, and movable sleeve can be offset, preventing the blade, rotating block, bearing sleeve, and movable sleeve from descending rapidly under gravity. This achieves a damping effect on the descent of the blade, rotating block, bearing sleeve, and movable sleeve under gravity. When the slider descends to its lowest point, the sliding plate can push the locking block outward and push the sliding plate below the locking block. Under the restoring force of the spring, the locking block continues to block the sliding plate, thus avoiding the upward assistance generated by the spring force of the spring returning when the blade, rotating block, bearing sleeve, and movable sleeve rise.

[0015] 3. This invention, by setting up a high-performance rubber sleeve II, a high-performance rubber sleeve I, a waterproof top, and a waterproof sleeve, generates vibrations due to friction during operation between the fixed base I, fixed base II, and the damping component. These vibrations are buffered by the high-performance rubber sleeve II and high-performance rubber sleeve I, preventing transmission to the suspension rod and achieving vibration isolation. Simultaneously, in rainy weather, the waterproof top and waterproof sleeve cover and block the fixed base II, fixed base I, and damping component, preventing rainwater from contacting the high-performance rubber sleeve II, high-performance rubber sleeve I, rubber sheets, and rubber blocks, thus extending their service life. Because the blades rotate and reciprocate under wind force, rainwater on the surface of the waterproof top and waterproof sleeve is accelerated, preventing rainwater from lingering on their surfaces for extended periods, thus slowing down the erosion rate of the waterproof top and waterproof sleeve and extending the overall service life of the shock absorber.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 12 As shown, the present invention provides a shock absorber, including a rod body 1, a support assembly 2, a conversion mechanism 3, and two energy dissipation mechanisms 4; The support assembly 2 is fixedly sleeved on the rod body 1, the conversion mechanism 3 is set on the support assembly 2, and two energy-consuming mechanisms 4 are respectively set above and below the support assembly 2 and connected to the conversion mechanism 3; The support assembly 2 includes a mounting sleeve 21, which is fixedly sleeved on the rod body 1, and a waterproof top 22 is fixedly sleeved on the upper part of the mounting sleeve 21. The conversion mechanism 3 includes a high-performance rubber sleeve 31, which is fixedly sleeved on the mounting sleeve 21. A fixed sleeve 315 is fixedly sleeved on the outside of the high-performance rubber sleeve 31. Limiting grooves 36 are opened on both sides of the fixed sleeve 315. A movable sleeve 33 is movably sleeved on the outside of the fixed sleeve 315. Sliding blocks 32 are connected to both sides of the inner wall of the movable sleeve 33 and are slidably installed inside the limiting grooves 36. A bearing sleeve 34 is fixedly sleeved on the outside of the movable sleeve 33. A rotating block 35 is movably installed on the outside of the bearing sleeve 34. Several blades 321 are arranged in a circle on the outside of the rotating block 35. The blades 321 are arranged along the tangent of the rotating block 35. The energy-consuming mechanism 4 includes a high-performance rubber sleeve 41, which is fixedly fitted onto the mounting sleeve 21. A fixing seat 42 is fixedly fitted onto the lower part of the outer side of the high-performance rubber sleeve 41, and a fixing seat 43 is fixedly fitted onto the upper part of the outer side of the high-performance rubber sleeve 41. A slide can be formed between the fixing seat 42 and the fixing seat 43. A damping component 44 is fitted between the fixing seat 42 and the fixing seat 43. A fixing plate 45 is connected to the outer side of the damping component 44. One side of the fixing plate 45 is connected to the rotating block 35. A waterproof sleeve 46 is fixedly fitted onto the outer side of the fixing plate 45 to cover the fixing seat 43 and the fixing seat 42. The waterproof sleeve 46 is located inside the waterproof top 22.

[0020] Using the above scheme: In a windy environment, wind from any direction will push the blade 321 and the rotating block 35 to deflect along the bearing sleeve 34. Simultaneously, the rotating block 35, the fixed plate 45, and the damping assembly 44 are all subjected to the rotational force of the blade 321, causing the bearing sleeve 34 to rise along the groove between the first fixed seat 42 and the second fixed seat 43. This, in turn, causes the blade 321, the rotating block 35, the bearing sleeve 34, the movable sleeve 33, and the slider 32 to rise along the interior of the limiting groove 36. During this rise, the damping assembly 44 generates friction with the inclined surface of the first fixed seat 42. Furthermore, the weight of the blade 321, rotating block 35, bearing sleeve 34, and movable sleeve 33 creates resistance, thereby achieving a wind damping effect and consuming some wind energy. As the blade 321 rotates and rises, the damping component 44 continues to generate friction with the fixed seat 42 as it descends between the first fixed seat 42 and the second fixed seat 43, thus achieving resistance to the rotation and descent of the blade 321 and rotating block 35. Under the action of wind, the blade 321 achieves a reciprocating up-and-down motion. This motion mode can replace the viscous damper used in wind-resistant shock absorbers.

[0021] like Figure 3 and Figure 4As shown, a fixing ring 37 is fixedly sleeved on the lower part of the fixed sleeve 315. A connecting ring 39 located between the movable sleeve 33 and the fixing ring 37 is movably sleeved on the outside of the fixed sleeve 315. Sliding pieces 310 located inside the limiting groove 36 are connected to both sides of the inner wall of the connecting ring 39. A buffer cotton 311 that can abut against the lower part of the movable sleeve 33 and the bearing sleeve 34 is connected to the top of the connecting ring 39.

[0022] The above solution is adopted: by setting buffer cotton 311, when the connecting ring 39 and the slider 310 rise rapidly, the buffer cotton 311 and the slider 32 can play a buffering role when they come into contact, so as to avoid the connecting ring 39 and the slider 310 from impacting and damaging the slider 32 and the movable sleeve 33, and from impact vibration.

[0023] like Figure 3 and Figure 4 As shown, a spring 38 is fitted on the outer side of the fixing sleeve 315. One end of the spring 38 is connected to the connecting ring 39, and the other end of the spring 38 is connected to the fixing ring 37.

[0024] The above scheme is adopted as follows: By setting spring 38, when the elastic force of spring 38 is restored and the buffer cotton 311 abuts against the bearing sleeve 34, the damping component 44 rises to the highest point of the tooth of the toothed sleeve 421. As the blade 321 continues to rotate, the damping component 44 can descend between the fixed seat 42 and the fixed seat 43. Since the movable sleeve 33 and the slider 32 are supported by the connecting ring 39 and the sliding plate 310, most of the downward gravity of the blade 321, the rotating block 35, the bearing sleeve 34 and the movable sleeve 33 can be offset, thus preventing the blade 321, the rotating block 35, the bearing sleeve 34 and the movable sleeve 33 from falling rapidly due to gravity. This can achieve the damping effect of the blade 321, the rotating block 35, the bearing sleeve 34 and the movable sleeve 33 falling due to gravity.

[0025] like Figures 8 to 12 As shown, the fixed sleeve 315 has movable grooves 312 located on both sides of the limiting groove 36 inside. The lower part of the movable groove 312 is equipped with a locking block 313 that slides left and right. The inner side of the locking block 313 extends into the interior of the limiting groove 36 and abuts against the top of the slide plate 310. The outer side of the locking block 313 is connected to a second spring 314. The other end of the second spring 314 is connected to the movable groove 312.

[0026] The above solution is adopted: by setting the locking block 313, when the locking block 313 moves outward, it will compress the second spring 314, causing the locking block 313 to retract into the interior of the movable groove 312 and release the obstruction of the slider 310. At this time, the first spring 38, which is in a compressed state, can push the connecting ring 39, the slider 310 and the buffer cotton 311 to move upward due to the recovery of the elastic force, and make the buffer cotton 311 abut against the bottom of the slider 32.

[0027] like Figures 8 to 12 As shown, a trapezoidal block 317 is slidably installed on the upper left and right side inside the movable groove 312. A spring 318 is connected to the outer side of the trapezoidal block 317, and the other end of the spring 318 is connected to the movable groove 312.

[0028] Using the above scheme: By setting trapezoidal block 317, when the damping component 44 rises to the higher position of the tooth of tooth sleeve 421, the slider 32 will rise to push the top rod 320, and drive the top rod 320 and inclined block 319 to push the trapezoidal block 317 to move outward, compressing the spring 318, thereby driving the trapezoidal block 317 to move outward.

[0029] like Figures 8 to 12 As shown, the bottom of the trapezoidal block 317 is connected to a connecting plate 316 located inside the movable groove 312. The other side of the connecting plate 316 is connected to the locking block 313. An inclined block 319 that can abut against the trapezoidal block 317 is movably sleeved above the movable groove 312. A top rod 320 is connected to the bottom of the inclined block 319. The bottom end of the top rod 320 passes through the fixed sleeve 315 and extends into the interior of the limiting groove 36.

[0030] Using the above solution: By setting the connecting plate 316, when the trapezoidal block 317 moves outward, the spring 318 can be compressed, and the connecting plate 316 can drive the locking block 313 to move outward, thereby driving the locking block 313 to move outward.

[0031] like Figures 5 to 7 As shown, the fixed base 42 includes a toothed sleeve 421, which is fixedly sleeved below the outer surface of the high-performance rubber sleeve 41. Damping blocks 422 are arranged on the inclined surface on the right side of the teeth of the toothed sleeve 421.

[0032] The above scheme is adopted: by setting a damping block 422, during the process of the damping assembly 44 descending between the fixed seat 42 and the fixed seat 43, the rubber block 442 will rub against the damping block 422. Through the deformation and reciprocating process of the rubber block 442 moving on the damping block 422 and restoring the engagement, the friction force of the blade 321 and the rotating block 35 during the descent process is increased.

[0033] like Figures 5 to 7 As shown, the fixing seat 2 43 includes a toothed sleeve 2 431, which is fixedly sleeved on the upper surface of the outer surface of the high-performance rubber sleeve 2 41. A damping block 2 432 is installed on the inclined surface on the left side of the tooth of the toothed sleeve 2 431, and the damping block 2 432 faces the damping block 1 422.

[0034] The above scheme is adopted: by setting a second damping block 432, during the process of the damping assembly 44 descending between the second fixed seat 43, the rubber block 442 will rub against the second damping block 432. Through the deformation generated by the movement of the rubber block 442 on the second damping block 432 and the reciprocating process of restoring the locking, the resistance of the blade 321 and the rotating block 35 during the descent process is increased.

[0035] like Figures 5 to 7 As shown, the damping assembly 44 includes a movable block 441, which is connected to the fixed plate 45. A number of rubber blocks 442 are connected to two corresponding sides of the movable block 441. The rubber blocks 442 are hollow and deformable. The rubber blocks 442 can be engaged between damping blocks 422 and damping blocks 432. Another set of two corresponding sides of the movable block 441 are connected to rubber sheets 443.

[0036] The above scheme is adopted: by setting rubber sheet 443 and rubber block 442, when rising, rubber sheet 443 generates friction with the inclined surface of tooth sleeve 421, and generates resistance with the weight of blade 321, rotating block 35, bearing sleeve 34 and movable sleeve 33, thereby achieving a wind damping effect and consuming some wind energy. When descending, the deformation and reciprocating process of rubber block 442 moving on damping block 422 and damping block 432 generates friction, thereby achieving resistance to the rotation and descent of blade 321 and rotating block 35, and producing the same damping effect as rising during the descent.

[0037] Working principle and usage process of this invention: In a windy environment, the wind will push the blade 321 and the rotating block 35 to deflect along the bearing sleeve 34. At the same time as the deflection, the rotating block 35, the fixed plate 45 and the damping component 44 are simultaneously subjected to the rotational force of the blade 321, causing the bearing sleeve 34 to rise along the groove between the fixed seat 1 42 and the fixed seat 2 43. At the same time, the blade 321, the rotating block 35, the bearing sleeve 34, the movable sleeve 33 and the slider 32 rise along the inside of the limiting groove 36. At the same time as the rise, the rubber sheet 443 generates friction with the inclined surface of the toothed sleeve 1 421, and generates resistance with the weight of the blade 321, the rotating block 35, the bearing sleeve 34 and the movable sleeve 33, which can play a role in wind damping, thereby consuming some wind energy and preventing the boom from vibrating. As the blade 321 rotates and rises. When the damping assembly 44 rises to the higher position of the tooth of the tooth sleeve 421, the slider 32 will rise to push the top rod 320, and drive the top rod 320 and the inclined block 319 to push the trapezoidal block 317 to move outward, compressing the spring 318. Through the connecting plate 316, the locking block 313 moves outward, compressing the spring 314, causing the locking block 313 to retract into the interior of the movable groove 312 and release the obstruction of the slider 310. At this time, the spring 38, which is in a compressed state, can push the connecting ring 39, the slider 310 and the buffer cotton 311 to move upward due to the elasticity recovery effect, and make the buffer cotton 311 abut against the bottom of the slider 32. During the contact between the buffer cotton 311 and the slider 32, it can play a buffering role to avoid the collision damage and impact vibration of the connecting ring 39 and the slider 310 with the slider 32 and the movable sleeve 33. When the damping assembly 44 rises to the highest point of the tooth of the toothed sleeve 421, as the blade 321 continues to rotate, the damping assembly 44 can descend between the fixed seat 42 and the fixed seat 43. Because the movable sleeve 33 and the slider 32 are supported by the connecting ring 39 and the sliding plate 310, they can counteract most of the downward gravity of the blade 321, the rotating block 35, the bearing sleeve 34, and the movable sleeve 33, preventing them from rapidly descending due to gravity. This effectively counteracts the downward gravity of the blade 321, the rotating block 35, the bearing sleeve 34, and the movable sleeve 33. The blade 321, rotating block 35, bearing sleeve 34 and movable sleeve 33 are damped by gravity as they descend. When the slider 32 descends to the lowest point, the descending slider 310 can press the locking block 313 to move outward and push the slider 310 below the locking block 313. Under the restoring force of the second spring 314, the locking block 313 is pushed to continue blocking the slider 310. This can avoid the upward assistance generated by the restoring force of the first spring 38 when the blade 321, rotating block 35, bearing sleeve 34 and movable sleeve 33 rise. As the damping assembly 44 descends between the first fixed seat 42 and the second fixed seat 43, the rubber block 442 rubs against the first damping block 422 and the second damping block 432. Through the deformation and reciprocating motion of the rubber block 442 moving on the first and second damping blocks 422, the frictional force of the blade 321 and the rotating block 35 during descent is increased, thereby achieving resistance to the rotational descent of the blade 321 and the rotating block 35. Furthermore, it produces the same damping effect during descent as during ascent. This motion method can replace the viscous damper used in wind-resistant shock absorbers and is not limited to a sealed environment, making it suitable for use in exposed environments. The frictional force generated by the operation and coordination between the first fixed seat 42, the second fixed seat 43, and the damping assembly 44 also produces vibration. This vibration can be controlled by high-performance... The second rubber sleeve 41 and the first high-performance rubber sleeve 31 provide cushioning, preventing vibration from being transmitted to the boom and thus achieving vibration isolation. Meanwhile, in rainy weather, the support assembly 2 and the energy dissipation mechanism 4 cover and block the second fixed seat 43, the first fixed seat 42, and the damping assembly 44, preventing rainwater from contacting the second high-performance rubber sleeve 41, the first high-performance rubber sleeve 31, the rubber sheet 443, and the rubber block 442, extending their service life. Because the blades 321 can rotate and reciprocate under wind force, they accelerate the falling of rainwater from the surfaces of the support assembly 2 and the energy dissipation mechanism 4, preventing rainwater from lingering on their surfaces for extended periods. This, to a certain extent, slows down the erosion rate of the support assembly 2 and the energy dissipation mechanism 4, extending their service life.
