Description

Technical Field

[0001] This application relates to the field of elevator vibration reduction technology, specifically to an elevator vibration reduction load-bearing device and its operating method. Background Technology

[0002] With the acceleration of urbanization and the continuous emergence of high-rise buildings, elevators, as key equipment for vertical transportation, are becoming increasingly important in terms of operational stability and safety. During elevator operation, the main unit experiences vibrations caused by uneven loading in different directions and by moving parts during the acceleration, constant speed operation, and deceleration phases. These vibrations are transmitted to the car through the steel cables, affecting the comfort of the car's operation. To improve the smoothness of the main unit's operation and the comfort of the car, vibration damping measures are necessary.

[0003] To address the vibration issues generated during elevator operation, several methods are commonly used. One method involves installing ordinary vibration-damping rubber pads between the elevator main unit and the mounting structure, utilizing the elasticity of the rubber to absorb some of the vibration energy. This method is relatively inexpensive, simple to install, and can mitigate vibration to some extent. Another method uses spring-loaded vibration damping devices, which buffer vibrations through the expansion and contraction of springs. The spring constant can be adjusted according to different elevator loads and operating requirements.

[0004] However, traditional damping rubber pads or spring damping devices typically bear the load directly on the main unit, lacking effective constraint on the vibration trajectory of the main unit. When the main unit generates complex vibrations due to eccentric forces or load changes, the damping elements not only bear vertical pressure but also horizontal shear or torsional forces. This multi-directional, disordered force state easily leads to premature failure of elastic elements due to fatigue and cannot guarantee optimal damping efficiency. Furthermore, due to the lack of a guiding mechanism, the main unit may experience uncontrollable swaying during vibration, affecting the overall stability of the system. Summary of the Invention

[0005] In order to solve the technical problems in the prior art, this application provides an elevator vibration damping and load-bearing device.

[0006] The elevator vibration damping and load-bearing device provided in this application adopts the following technical solution: An elevator vibration damping and load-bearing device includes: The main beam is installed in the elevator shaft, and both ends of the main beam are located in the openings in the side wall of the elevator shaft; A first damping mechanism, disposed on the main beam, includes an upper mounting plate and a lower mounting plate for mounting the elevator main unit, and two first elastic members installed between the upper and lower mounting plates. The upper and lower mounting plates are rotatably connected via a first rotating shaft. The two first elastic members are symmetrically distributed about the first rotating shaft, and their upper and lower ends are respectively connected to the upper and lower mounting plates. Two second damping mechanisms are respectively disposed below both ends of the main beam. Each second damping mechanism includes a top plate, a bottom plate supported on the bottom surface of the opening, and two second elastic members installed between the top plate and the bottom plate. The top plate and the bottom plate are rotatably connected by a second rotating shaft. The two second elastic members are symmetrically distributed about the second rotating shaft, and the upper and lower ends of the two second elastic members are respectively connected to the top plate and the bottom plate.

[0007] By adopting the above technical solution, the cooperation of the first and second damping mechanisms utilizes the limiting effect of the rotating shaft to convert the multi-directional disordered vibrations generated during the operation of the elevator main unit into unidirectional oscillations. This structure allows the symmetrically arranged and abutting first or second elastic elements to more effectively absorb vibration energy in a single direction, effectively improving energy absorption efficiency and suppressing vibration rebound. This device achieves dual-direction damping, reduces operating noise, and extends the service life of the main unit and related components.

[0008] Preferably, the first shock absorption mechanism further includes a third elastic element, one end of which abuts against the side of the upper mounting plate opposite to the first elastic element, and the other end abuts against the elevator host.

[0009] By adopting the above technical solution, when the first elastic element rebounds, the third elastic element uses its own deformation to perform secondary buffering and absorption of the energy released by the rebound of the first elastic element, thereby blocking the direct transmission of the rebound impact force to the elevator host and protecting the elevator host from the impact of the rebound.

[0010] Preferably, the first damping mechanism further includes a hydraulic self-balancing assembly installed between the upper mounting plate and the lower mounting plate. The hydraulic self-balancing assembly includes a base with a communicating cavity inside, two first push rods respectively disposed at both ends of the base, and two plugs. The communicating cavity includes a U-shaped communicating space filled with damping fluid, and a stroke space located at both ends of the communicating portion and extending vertically upward. The two plugs are respectively sealed and slidably installed in the two stroke spaces. One end of the first push rod extends into the stroke space and is fixedly connected to the plug, and the other end is connected to the upper mounting plate.

[0011] By adopting the above technical solution, when one side of the upper mounting plate is pressed and moves downward, the plug on the pressed side moves downward, squeezing the damping fluid through the U-shaped connecting space to the other side, forcing the plug and push rod on the other side to move upward. The damping fluid generates fluid resistance when flowing through the connecting space, which can dissipate the kinetic energy of vibration and also buffer instantaneous impact loads.

[0012] Preferably, the upper mounting plate has two sliding grooves, each groove is provided with a slider, each slider is hinged to the end of the corresponding first push rod away from the plug, each slider has a fourth elastic member abutting on both sides, each fourth elastic member is accommodated in the sliding groove, and one end of each fourth elastic member is fixed to the slider and the other end is fixed to the extended end of the sliding groove.

[0013] By adopting the above technical solution, when the upper mounting plate tilts and swings around the first rotating shaft, the slider slides in the groove to compensate for the horizontal displacement difference caused by the rotation of the upper mounting plate. In conjunction with the hinge structure, it adapts to the angle change, avoiding the bending deformation of the top rod or the leakage of the seal due to lateral force wear caused by the rigid connection, and preventing mechanical jamming. In addition, during the swinging process of the upper mounting plate, the fourth elastic element can absorb and suppress the horizontal swing kinetic energy generated when the upper mounting plate swings.

[0014] Preferably, the upper mounting plate has a ball groove on the side facing the hydraulic self-balancing assembly. The hydraulic self-balancing assembly also includes a second push rod and a fifth elastic element. The base also has an insertion hole. The fifth elastic element is located in the insertion hole. One end of the second push rod is accommodated in the insertion hole and connected to the fifth elastic element, and the other end cooperates with the ball groove.

[0015] By adopting the above technical solution, the cooperation between the second push rod and the ball groove forms a universal connection similar to a ball joint, which ensures that while providing additional vertical support to the upper mounting plate, it does not interfere with the tilting and swinging of the upper mounting plate in all directions. At the same time, the ball head extends into the ball groove, which restricts the degree of freedom of the upper mounting plate in the horizontal dimension, preventing it from horizontally misaligning or falling off during severe vibration.

[0016] Preferably, the hydraulic self-balancing assembly further includes a flow control valve disposed in the communicating space and an attitude monitoring sensor disposed at one end of the upper mounting plate. The first damping mechanism further includes a control unit, which is communicatively connected to the flow control valve and the attitude monitoring sensor respectively. The control unit is used to receive the real-time vibration signal fed back by the attitude monitoring sensor and can adjust the valve opening of the flow control valve.

[0017] By adopting the above technical solution, when the sensor detects a low vibration amplitude but a high frequency, the control unit instructs the flow control valve to increase its opening. At this time, the damping fluid resistance of the connecting space decreases, and the fluid converts kinetic energy into heat energy during the flow process, thereby dissipating the energy generated by the vibration. At the same time, the rigid transmission channel of the high-frequency vibration wave is cut off. When the sensor detects a sudden increase in vibration amplitude, the control unit instructs the flow control valve to rapidly decrease its opening. At this time, the fluid resistance surges to increase the damping force, thereby rapidly attenuating the large vibration energy and suppressing excessive swaying of the upper mounting plate.

[0018] Preferably, each of the first elastic elements includes multiple buffer blocks, and the hydraulic self-balancing assembly further includes two injection components, each including a liquid storage shell, a piston pusher slidably installed inside the liquid storage shell, and a drive unit for driving the piston pusher and communicating with the control unit. The liquid storage shells of the two injection components are respectively connected to both ends of the communicating space, and the drive unit and the liquid storage shell are both embedded between the multiple buffer blocks.

[0019] By adopting the above technical solution, when the sensor detects that the elevator main unit is tilted to one side, the control unit commands the left-side injection component to operate, pushing the pusher forward to inject more hydraulic oil. The increased hydraulic oil volume forcibly lifts the left-side plug, restoring the upper mounting plate to a horizontal position. This embeds the reservoir and drive unit between multiple buffer blocks, allowing the buffer blocks to protect the injection component.

[0020] An operating method for an elevator vibration damping and load-bearing device, the method comprising the following steps: S1. Before installing the elevator host and the first top rod, inject the damping fluid into the connecting cavity and let it stand until the liquid level at both ends of the connecting space is naturally balanced and in a static state. S2. The control unit commands the flow control valve to close completely, blocking the fluid flow in the connected space, and using the incompressible fluid properties to form rigid hydraulic support columns of equal height at both ends of the connected space. S3. Install the two first push rods and the upper mounting plate onto the hydraulic self-balancing assembly. At this time, because the fluid is locked and cannot flow, the first push rods on both sides are restricted to the same height, thereby ensuring that the upper mounting plate is automatically in a horizontal state after installation. S4. After confirming that the elevator host is installed and fixed, the control unit instructs the flow control valve to open to the preset opening degree, so that the equipment enters the standby working state. S5. The control unit receives the signal from the attitude monitoring sensor and sends an opening adjustment command to the flow control valve according to the signal characteristics to perform dynamic damping adjustment. S6. The control unit sends a drive command to the drive unit according to the tilt state of the upper mounting plate to change the fluid volume in the communicating cavity.

[0021] By adopting the above technical solution, the principle of fluid communication and hydraulic locking characteristics are utilized to achieve self-leveling and rigid support of the upper mounting plate without the need for complicated leveling tools during the installation stage, which reduces the installation difficulty and ensures the initial installation accuracy.

[0022] Preferably, the dynamic damping adjustment in step S5 specifically includes the following steps: S51. The attitude monitoring sensor continuously collects vibration data from the upper mounting plate and sends the vibration signal, which includes vibration amplitude data and vibration frequency data, to the control unit. S52. The control unit receives the vibration signal and compares the vibration amplitude data with a pre-stored preset safe amplitude threshold, and compares the vibration frequency data with a pre-stored preset high frequency threshold. S53. When the comparison result shows that the vibration amplitude is lower than the preset safe amplitude threshold and the vibration frequency is higher than the preset high frequency threshold, the control unit sends an instruction to increase the opening of the flow control valve; when the comparison result shows that the vibration amplitude is higher than the preset safe amplitude threshold, the control unit sends an instruction to decrease the opening of the flow control valve.

[0023] By adopting the above technical solutions, for high-frequency, low-amplitude vibrations, the valve opening is increased, the fluid damping is reduced, and the energy is dissipated by the fluid viscosity, thus reducing noise transmission; for large-amplitude vibrations, the valve opening is reduced, the fluid damping is increased instantaneously, and a near-rigid support is formed to prevent the equipment from undergoing excessive displacement.

[0024] Preferably, the anti-overturning correction in step S6 specifically includes the following steps: S61. The control unit receives the signal fed back by the attitude monitoring sensor and analyzes the current real-time tilt angle value and tilt direction of the upper mounting plate. S62. The control unit compares the real-time tilt angle value with a preset tilt correction threshold. The preset tilt correction threshold is greater than the upper limit of the preset horizontal zero position interval. When the real-time tilt angle value is greater than the preset tilt correction threshold, the control unit sends a start command to the drive unit located on the lower side of the tilt direction. S63. The drive unit responds to the start command and drives the piston pusher to move into the liquid storage shell, presses the damping fluid in the liquid storage shell into the communicating space, and lifts the plug on that side. S64. The control unit continuously monitors the real-time tilt angle value fed back by the attitude monitoring sensor and compares the value with the preset horizontal zero position interval. When the real-time tilt angle value falls within the preset horizontal zero position interval, the control unit sends a stop command to the drive unit.

[0025] By adopting the above technical solution, setting an angle threshold to trigger fluid injection compensation actively increases the volume of hydraulic oil on the lower side, forcibly lifting the sunken side, thereby preventing the elevator main unit from overturning.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The cooperation of the first and second damping mechanisms utilizes the limiting effect of the rotating shaft to convert the multi-directional disordered vibrations generated during the operation of the elevator main unit into unidirectional oscillations. This structure allows the symmetrically arranged and abutting first or second elastic elements to more effectively absorb vibration energy in a single direction, effectively improving energy absorption efficiency and suppressing vibration rebound. This device achieves dual-direction damping, reduces operating noise, and extends the service life of the main unit and related components.

[0027] 2. When the upper mounting plate tilts and swings around the first pivot, the slider slides in the groove to compensate for the horizontal displacement difference caused by the rotation of the upper mounting plate. It adapts to the angle change in conjunction with the hinge structure, avoiding the bending deformation of the top rod or the leakage of the seal due to lateral force wear caused by the rigid connection, and preventing mechanical jamming. In addition, during the swinging process of the upper mounting plate, the fourth elastic element can absorb and suppress the horizontal swinging kinetic energy generated when the upper mounting plate swings.

[0028] 3. When the sensor detects a low vibration amplitude but a high frequency, the control unit instructs the flow control valve to increase its opening. At this time, the damping fluid resistance in the connecting space decreases, and the fluid converts kinetic energy into heat energy during the flow, thereby dissipating the energy generated by the vibration. At the same time, it cuts off the rigid transmission channel of the high-frequency vibration wave. When the sensor detects a sudden increase in vibration amplitude, the control unit instructs the flow control valve to rapidly decrease its opening. At this time, the fluid resistance surges to increase the damping force, thereby quickly attenuating the large vibration energy and suppressing excessive swaying of the upper mounting plate.

[0029] 4. When the sensor detects that the elevator main unit is tilted to one side, the control unit commands the left-side injection component to operate, pushing the pusher forward to inject more hydraulic oil. The increased hydraulic oil volume forcibly lifts the left-side plug, restoring the upper mounting plate to a horizontal position. This embeds the reservoir housing and drive unit between multiple buffer blocks, allowing the buffer blocks to protect the injection component. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail. Example

[0032] Embodiment 1 of this application discloses an elevator vibration damping and load-bearing device. (Refer to...) Figure 1-2 An elevator vibration damping load-bearing device includes a main beam 1, a first damping mechanism 2, and two second damping mechanisms 3. The main beam 1 is mounted on an elevator shaft 6, with both ends of the main beam 1 located in openings 61 in the side walls of the elevator shaft 6. The first damping mechanism 2 is mounted on the main beam 1, and the two second damping mechanisms 3 are respectively located below both ends of the main beam 1.

[0033] Specifically, the main beam 1 is made of high-strength steel and is rectangular in shape, with both ends designed to fit the openings 61 in the side walls of the elevator shaft 6. In some embodiments, the main beam 1 may also be made of materials such as aluminum alloy. The main beam 1 is fixedly connected to the side walls of the elevator shaft 6 by bolts or other connectors. As the main load-bearing frame, the main beam 1 bears the weight and dynamic load of the elevator main unit 5 and transmits these loads to the building structure. Sound insulation felt is also installed on the side walls of the main beam 1 to absorb the noise generated by the vibration of the main beam 1.

[0034] Please refer to the following: Figure 3 , Figure 3 yes Figure 1 The enlarged view of area A shows that the first damping mechanism 2 includes an upper mounting plate 21, a lower mounting plate 22 for mounting the elevator main unit 5, and two first elastic members 24 installed between the upper mounting plate 21 and the lower mounting plate 22. The upper mounting plate 21 and the lower mounting plate 22 are made of steel plates. The upper mounting plate 21 is fixed to the elevator main unit 5 by bolts, and the lower mounting plate 22 is fixed to the main unit beam 1 by bolts. The upper mounting plate 21 and the lower mounting plate 22 are rotatably connected by a first rotating shaft 23, which is made of alloy steel. The two first elastic members 24 are symmetrically distributed about the first rotating shaft 23, and their upper and lower ends are connected to the upper mounting plate 21 and the lower mounting plate 22, respectively. Each first elastic member 24 includes multiple buffer blocks 241, which are made of rubber and are fixedly connected to the upper mounting plate 21 and the lower mounting plate 22 by glue or bolts.

[0035] When the elevator host 5 vibrates during operation, the first rotating shaft 23 restricts the displacement freedom of the upper mounting plate 21 relative to the lower mounting plate 22, converting the multi-directional disordered vibration generated by the elevator host 5 into unidirectional oscillation around the first rotating shaft 23. At this time, the first elastic members 24, which are symmetrically arranged about the rotating shaft, are in a compressed or stretched abutment state, specifically absorbing the vibration energy generated by the unidirectional rotation. The first elastic members 24 convert mechanical energy into heat energy, thereby improving energy absorption efficiency and preventing vibration rebound.

[0036] The first damping mechanism 2 also includes a third elastic element 25. One end of the third elastic element 25 abuts against the side of the upper mounting plate 21 opposite to the first elastic element 24, and the other end abuts against the elevator host 5. The third elastic element 25 is made of rubber or spring. The third elastic element 25 is located on the contact surface between the host and the upper mounting plate 21. When the first elastic element 24 is compressed and rebounds, the upper mounting plate 21 will have a reverse movement tendency. At this time, the third elastic element 25 is compressed and uses its own deformation to perform secondary buffering and absorption of the energy released by the rebound of the first elastic element 24, thereby blocking the direct transmission of the rebound impact force to the elevator host 5 and protecting the elevator host 5 from the rebound impact.

[0037] Please refer to the following: Figure 4 , Figure 4 yes Figure 1 The enlarged view of area B shows that each second damping mechanism 3 includes a top plate 31, a bottom plate 32, and two second elastic elements 33 installed between the top plate 31 and the bottom plate 32. The top plate 31 and the bottom plate 32 are rotatably connected by a second rotating shaft 34. The two second elastic elements 33 are symmetrically distributed about the second rotating shaft 34, and their upper and lower ends are connected to the top plate 31 and the bottom plate 32, respectively. The second elastic elements 33 can be rubber blocks or springs. The working principle of the second damping mechanism 3 is similar to that of the first damping mechanism 2, also using a rotating shaft to convert vibration into unidirectional oscillation. This configuration constitutes a double-redirection damping structure: the first damping mechanism 2 directly filters the high-frequency vibration from the main unit source, and the residual vibration after attenuation is transmitted to the main unit beam 1, where it is further absorbed by the second damping mechanisms 3 at both ends of the main unit beam 1, reducing the operating noise ultimately transmitted to the shaft sidewall and extending the service life of the main unit and related components.

[0038] The implementation principle of this embodiment is as follows: When the elevator host 5 is running, it generates multi-dimensional disordered vibrations, which are first transmitted to the upper mounting plate 21. Due to the rigidity limitation of the first rotating shaft 23, the upper mounting plate 21 cannot be horizontally displaced or arbitrarily twisted relative to the lower mounting plate 22, and all vibration energy is forcibly converted into unidirectional reciprocating oscillations around the first rotating shaft 23.

[0039] During the oscillation of the upper mounting plate 21 around the axis, due to the lever effect, the first elastic elements 24 located on both sides of the axis alternately resist the oscillation torque through compression and stretching deformation. The rubber material has high damping characteristics, and in the repeated hysteresis deformation, it converts mechanical kinetic energy into heat energy for dissipation, thereby attenuating the vibration amplitude.

[0040] When the first elastic element 24 is compressed and releases its elastic potential energy to rebound, the upper mounting plate 21 will squeeze the third elastic element 25 located on the contact surface of the main unit. The third elastic element 25 uses its own compression deformation to absorb the rebound energy a second time, cutting off the reverse impact path of the vibration energy to the elevator main unit 5 body. Example

[0041] Please see Figure 5 , Figure 5 This is a front view of the first shock-absorbing mechanism 2 in Embodiment 2 of this application. The difference between this embodiment and the above embodiment is that the first shock-absorbing mechanism 2 further includes a hydraulic self-balancing component 26 installed between the upper mounting plate 21 and the lower mounting plate 22. The first rotating shaft 23 includes two coaxially arranged sections. The hydraulic self-balancing component is located between the two sections of the first rotating shaft 23. In actual use, multiple hydraulic self-balancing components 26 can also be set in the direction perpendicular to the main beam 1 to replace the first rotating shaft 23.

[0042] Please refer to the following: Figure 6-7 , Figure 6 This is a cross-sectional view of the first damping mechanism 2 in Embodiment 2 of this application. The hydraulic self-balancing assembly 26 includes a base 261 with an internal communicating cavity 262, two first push rods 263 respectively disposed at both ends of the base 261, and two plugs 264. The base 261 is made of materials such as cast iron. The communicating cavity 262 includes a U-shaped communicating space 2621 filled with damping fluid, and a stroke space 2622 located at both ends of the communicating portion and extending vertically upward. The damping fluid is hydraulic oil. The two plugs 264 are respectively sealed and slidably installed in the two stroke spaces 2622. One end of the first push rod 263 extends into the stroke space 2622 and is fixedly connected to the plug 264, and the other end is connected to the upper mounting plate 21. When the upper mounting plate 21 is subjected to vibration and moves downward under pressure on one side, the first push rod 263 on the pressure side pushes the plug 264 downward, squeezing the damping fluid through the U-shaped connecting space 2621 to the other side, forcing the plug 264 and push rod on the other side to move upward. The damping fluid generates friction and local resistance as it flows through the connecting space 2621 and pipe bends, thus dissipating the kinetic energy of the vibration. When the equipment is subjected to an instantaneous impact load, the first push rod 263 pushes the plug 264 downward rapidly, causing a surge in fluid velocity. Since fluid resistance is proportional to the square of the velocity, the fluid resistance increases as it flows through narrow channels and bends, thus limiting the downward acceleration of the first push rod 263, converting the instantaneous impact force into a smooth pressure fluctuation, thereby dissipating the kinetic energy of the vibration and buffering the instantaneous impact load.

[0043] The upper mounting plate 21 has two grooves 211 facing the hydraulic self-balancing assembly 26. Each groove 211 contains a slider 212, and each slider 212 is hinged to the end of the corresponding first push rod 263 away from the plug 264. The sliders 212 are made of wear-resistant materials such as copper alloy. Each slider 212 has a fourth elastic element 213 abutting on both sides. Each fourth elastic element 213 is accommodated in the groove 211, and one end of each fourth elastic element 213 is fixed to the slider 212, while the other end is fixed to the extended end of the groove 211. The fourth elastic element 213 is a spring. When the upper mounting plate 21 tilts and swings around the first rotating shaft 23, the connection point will generate an arc trajectory around the shaft, which has a horizontal component. At this time, the slider 212 slides in the groove 211 to compensate for the horizontal displacement difference caused by the rotation of the upper mounting plate 21, and adapts to the angle change in conjunction with the hinge structure, avoiding the bending deformation of the push rod or the leakage of the seal due to lateral force wear caused by the rigid connection, and preventing mechanical jamming. In addition, during the swinging process of the upper mounting plate 21, the fourth elastic element 213 set on both sides of the slider 212 is deformed by pressure, which can absorb and suppress the horizontal swing kinetic energy generated when the upper mounting plate swings.

[0044] The upper mounting plate 21 has a ball groove 214 on the side facing the hydraulic self-balancing assembly 26. The hydraulic self-balancing assembly 26 also includes a second push rod 265 and a fifth elastic element 266. The base 261 also has a socket 2611. The fifth elastic element 266 is a spring located in the socket 2611. One end of the second push rod 265 is accommodated in the socket 2611 and connected to the fifth elastic element 266, while the other end engages with the ball groove 214. The second push rod 265 is pushed upward under the elastic force of the fifth elastic element 266. The ball head of the second push rod 265 and the ball groove 214 form a universal connection similar to a ball joint. This structure provides the upper mounting plate 21 with additional vertical elastic support force without interfering with the tilting and swinging of the upper mounting plate 21 in all directions. In addition, the ball head extends into the ball groove 214, restricting the degree of freedom of the upper mounting plate 21 in the horizontal dimension and preventing it from horizontally misaligning or falling off during severe vibration.

[0045] The hydraulic self-balancing assembly 26 also includes a flow control valve 267 disposed within the communicating space 2621 and an attitude monitoring sensor 268 disposed at one end of the upper mounting plate 21. The attitude monitoring sensor 268 can be an integrated six-axis inertial sensor module, which is fixed to the center position of the upper surface of the upper mounting plate 21 by bolts. It integrates a three-axis accelerometer and a three-axis gyroscope, and can directly sense and output real-time tilt angle data of the upper mounting plate 21 relative to the horizontal plane and vertical vibration acceleration data. The first damping mechanism 2 also includes a control unit 4, which is fixedly disposed on the side wall of the main beam 1. The control unit 4 is an industrial electronic control device integrating a microprocessor, memory, and input / output interface circuits, such as a single-chip microcomputer controller or a PLC controller.

[0046] Please refer to the following: Figure 8 , Figure 8 This is a cross-sectional view of the injection component 269 in Embodiment 2 of this application. The hydraulic self-balancing assembly 26 also includes two injection components 269, each comprising a reservoir housing 2691, a piston pusher 2692 slidably mounted inside the reservoir housing 2691, and a drive unit 2693 for driving the piston pusher 2692 and communicating with the control unit 4. The reservoir housings 2691 of the two injection components 269 are respectively connected to both ends of the communicating space 2621. The drive unit 2693 and the reservoir housings 2691 are both embedded between multiple buffer blocks 241, using the buffer blocks 241 as external protection to protect the injection components 269. When the sensor detects that the elevator host 5 is tilted to one side, the control unit 4 commands the injection component 269 on the tilted side to work. The drive unit 2693 drives the piston pusher 2692 to advance, pressing the hydraulic oil in the reservoir housing 2691 into the communicating space 2621. At this time, the volume of hydraulic oil in the connecting space 2621 increases, forcibly lifting the plug 264 on that side, so that the upper mounting plate 21 returns to a horizontal position.

[0047] The control unit 4 establishes electrical connections with the attitude monitoring sensor 268 and the flow control valve 267 via data cables. The control unit 4 directly reads the digital signal output by the attitude monitoring sensor 268 and compares the real-time tilt angle data with a preset correction threshold to control the start and stop of the injection component 269. Simultaneously, it analyzes the current vibration amplitude and frequency based on vibration acceleration data, thereby dynamically adjusting the opening of the flow control valve 267 to achieve variable damping vibration reduction. The control unit 4 receives real-time vibration signals from the attitude monitoring sensor 268 and dynamically adjusts the valve opening of the flow control valve 267 according to the amplitude of the real-time vibration signal. When the sensor detects a low vibration amplitude but a high frequency, the control unit 4 instructs the flow control valve 267 to increase its opening. At this time, the damping fluid flow cross-section of the connecting space 2621 increases, the resistance decreases, and the fluid mainly utilizes viscous damping to convert kinetic energy into heat energy during rapid reciprocating flow, while simultaneously cutting off the rigid transmission channel of the high-frequency vibration wave. When the sensor detects a sudden increase in vibration amplitude, such as an elevator sudden stop or start, the control unit 4 instructs the flow control valve 267 to quickly reduce its opening. At this time, the resistance of the fluid flowing through the valve port increases sharply, the system damping force increases, forming a near-rigid support, thereby quickly attenuating large vibration energy and suppressing excessive swaying of the upper mounting plate 21.

[0048] The working principle of this embodiment is as follows: When the upper mounting plate 21 is affected by vibration and moves downward under pressure on one side, the first push rod 263 on the pressure side pushes the plug 264 downward, forcing the damping fluid in the connecting cavity 262 to flow to the other side. Under the slight vibration of normal operation, the fluid flow rate is slow, mainly providing basic viscous damping.

[0049] Meanwhile, when the upper mounting plate 21 swings around the first pivot 23, the motion trajectory generated at the connection point is arc-shaped, which includes a horizontal component. The slider 212 slides horizontally within the groove 211 to compensate for the horizontal displacement difference caused by the rotation of the upper mounting plate 21, eliminating the bending stress of the push rod caused by the rigid connection. The fourth elastic members 213 on both sides of the slider 212 are deformed under pressure when the slider 212 moves, absorbing the horizontal swaying energy converted from the swing.

[0050] In addition, the hydraulic self-balancing component 26 also has a semi-active control function. When the attitude monitoring sensor 268 detects high-frequency, low-amplitude vibration, the control unit 4 instructs the flow control valve 267 to increase its opening, reducing the throttling resistance of the fluid flow. The system mainly utilizes the viscosity of the fluid to filter noise. When a large-amplitude vibration is detected, the control unit 4 instructs the flow control valve 267 to decrease its opening, artificially increasing the resistance of the fluid passing through the valve port, so that the system presents a near-rigid support state to suppress the violent shaking of the main unit. If the main unit tilts, the control unit 4 will activate the drive unit 2693 on the lower side, pushing the piston to force the hydraulic oil in the reservoir into the communicating space 2621, increasing the volume of hydraulic oil on that side and lifting the plug 264 until the upper mounting plate 21 returns to horizontal. Example

[0051] The operation method of the elevator vibration damping load-bearing device provided in this application embodiment includes the following steps: S1. Before installing the elevator main unit 5 and the first top rod 263, inject damping fluid into the connecting cavity 262 and let it stand until the liquid levels at both ends of the connecting space 2621 are naturally balanced and in a static state. This step is mainly to remove air bubbles in the pipeline and establish an initial horizontal liquid level reference.

[0052] S2 and control unit 4 command the flow control valve 267 to completely close, blocking the fluid flow within the connecting space 2621. Utilizing the incompressible fluid properties, rigid hydraulic support columns of equal height are formed at both ends of the connecting space 2621. At this time, the connecting space 2621 is physically isolated, preventing the fluid on both sides from flowing to each other, thus creating a hydraulically locked state and providing a stable rigid support point for the upper components.

[0053] S3. Install the two first push rods 263 and the upper mounting plate 21 onto the hydraulic self-balancing assembly 26. At this time, because the fluid is locked and cannot flow, the first push rods 263 on both sides are restricted to the same height, thereby ensuring that the upper mounting plate 21 is automatically in a horizontal state after installation. Utilizing the principle of fluid communication and the characteristics of hydraulic locking, the self-leveling and rigid support of the upper mounting plate 21 can be achieved without complex leveling tools during the installation stage, reducing the installation difficulty and ensuring the initial installation accuracy.

[0054] S4. After confirming that the elevator main unit 5 is installed and fixed, the control unit 4 instructs the flow control valve 267 to open to the preset opening degree, putting the equipment into standby mode. This releases the hydraulic lock, restores the fluid connectivity of the system, and enables the equipment to have shock absorption capabilities.

[0055] S5. Control unit 4 receives the signal from attitude monitoring sensor 268 and sends an opening adjustment command to flow control valve 267 based on the signal characteristics to perform dynamic damping adjustment. Specifically, this includes the following steps: S51, the attitude monitoring sensor 268 continuously collects vibration data from the upper mounting plate 21 and sends the vibration signal, which includes vibration amplitude data and vibration frequency data, to the control unit 4.

[0056] S52, Control Unit 4 receives vibration signals and compares the vibration amplitude data with the preset safe amplitude threshold and the vibration frequency data with the preset high frequency threshold.

[0057] S53. When the comparison result shows that the vibration amplitude is lower than the preset safe amplitude threshold and the vibration frequency is higher than the preset high frequency threshold, the control unit 4 sends a command to increase the opening of the flow control valve 267; when the comparison result shows that the vibration amplitude is higher than the preset safe amplitude threshold, the control unit 4 sends a command to decrease the opening of the flow control valve 267. For high-frequency, low-amplitude vibrations, the system increases the valve opening to reduce fluid damping, dissipates energy using fluid viscosity, and reduces noise transmission; for large-amplitude vibrations, the system decreases the valve opening to instantly increase fluid damping and prevent excessive displacement of the equipment.

[0058] S6. Control unit 4 sends a drive command to drive unit 2693 according to the tilt state of upper mounting plate 21, changing the fluid volume in communicating cavity 262. Specifically, this includes the following steps: S61, the control unit 4 receives the signal fed back by the attitude monitoring sensor 268 and analyzes the current real-time tilt angle value and tilt direction of the upper mounting plate 21.

[0059] S62, the control unit 4 compares the real-time tilt angle value with the preset tilt correction threshold. When the real-time tilt angle value is greater than the preset tilt correction threshold, the control unit 4 sends a start command to the drive unit 2693 located on the lower side of the tilt direction.

[0060] S63, in response to the start command, the drive unit 2693 drives the piston pusher 2692 to move into the reservoir housing 2691, forcing the damping fluid in the reservoir housing 2691 into the communicating space 2621, thus lifting the plug 264 on that side. By actively increasing the volume of hydraulic oil on the lower side, Pascal's principle is used to forcibly lift the sunken side.

[0061] S64, the control unit 4 continuously monitors the real-time tilt angle value fed back by the attitude monitoring sensor 268 and compares this value with a pre-stored preset horizontal zero-position interval. When the real-time tilt angle value falls within the preset horizontal zero-position interval, the control unit 4 sends a stop command to the drive unit 2693. By setting an angle threshold to trigger liquid injection compensation, the risk of overturning of the elevator main unit 5 due to long-term accumulation of small displacements is prevented.

[0062] The working principle of this embodiment is as follows: During the installation phase, damping fluid is first injected into the communicating cavity 262 and allowed to settle. Utilizing the principle of communicating vessels, the liquid levels at both ends are naturally balanced, establishing a horizontal reference. Subsequently, the control unit 4 commands the flow control valve 267 to completely close, cutting off fluid exchange between the left and right sides of the communicating space 2621. Based on the incompressible nature of liquids, the fluid enclosed within the two side travel spaces 2622 forms two rigid hydraulic support columns with fixed heights. At this time, the height of the first push rod 263 is locked on the same horizontal plane, thus ensuring that the elevator main unit 5 is automatically in a horizontal state after installation without the aid of external precision leveling tools.

[0063] Simultaneously, the control unit 4 continuously receives signals from the attitude monitoring sensor 268 and compares the vibration amplitude and frequency data with preset safety amplitude thresholds and high-frequency thresholds, respectively. Based on the comparison results, the system dynamically adjusts the opening of the flow control valve 267, automatically switching between a "high-pass, low-resistance" noise reduction mode and a "low-pass, high-resistance" impact resistance mode. At the same time, the control unit 4 monitors the tilt angle of the upper mounting plate 21 in real time. Once the tilt angle exceeds a preset correction threshold, the liquid injection program is initiated for compensation. The system operates through a cyclical process of "angle detection, liquid injection, and feedback change" until the tilt angle falls within the preset horizontal zero-position range, thus ensuring high-precision leveling and preventing the elevator main unit 5 from tipping over.

[0064] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of this application.
