Description
Technical Field
[0001] This invention relates to a seismic isolation / vibration device, belonging to the field of structural seismic isolation and vibration control technology, and in particular to a built-in energy-dissipating anti-crushing vertical seismic isolation / vibration support. Background Technology
[0002] Meanwhile, with the development of urban rail transit, especially when the track is close to buildings, train operation can cause structural vibrations, affecting building safety and residents' comfort. In recent years, the "industrial buildings moving into buildings" initiative has been vigorously promoted, and the operation of machinery and equipment inside these buildings can also cause excessive vibrations, impacting structural safety and human comfort.
[0003] The development of vertical seismic isolation / vibration control technology is mostly accompanied by the development of seismic isolation / vibration control bearings. Currently developed bearings focus on achieving vibration isolation / vibration control functions, but their energy dissipation capacity is relatively weak. Under large earthquake loads, bearing failure may lead to crushing instability, seriously affecting the safety and stability of the superstructure. There is an urgent need to invent a vertical seismic isolation / vibration control bearing with high energy dissipation capacity and effective prevention of bearing crushing instability. Summary of the Invention
[0004] The technical problem that this invention aims to solve is the crushing and instability of existing vertical vibration isolation supports.
[0005] The present invention adopts the following technical solution:
[0006] An internal energy-dissipating anti-crushing vertical vibration isolation support includes an upper cylinder 13, a lower cylinder 12, a lower connecting plate 2, and an upper connecting plate 1. The lower connecting plate 2 serves as a fixed base, with its upper part fixedly connected to the upper cylinder 13. The lower cylinder 12 is sleeved on the outside of the upper cylinder 13, and the upper connecting plate 1 is fixedly connected to the upper end of the lower cylinder 12. A lower limiting ring 9 is fixed to the inner wall of the upper cylinder 13, and the upper end of the lower limiting ring 9 abuts against a spring limiting plate 8. The upper connecting plate 1 and the spring limiting plate 8 each have a corresponding central hole. An energy-dissipating outer cylinder 4 extends downward from the central hole of the upper connecting plate 1 and is fixed thereon. The energy-dissipating outer cylinder 4 can pass downward through the central hole of the spring limiting plate 8. An energy-dissipating device is fixedly installed inside the energy-dissipating outer cylinder 4. The device includes an energy-consuming upper sealing plate 5, an energy-consuming lower sealing plate 6, an energy-consuming guide rod 7, and an energy-consuming piston 14. The energy-consuming upper sealing plate 5 and the energy-consuming lower sealing plate 6 are fixed to the inner wall of the energy-consuming outer cylinder. The energy-consuming guide rod 7 movably passes through the center hole of the energy-consuming upper sealing plate 5 and the energy-consuming lower sealing plate 6, and its lower end is fixedly connected to the lower connecting plate 2. The energy-consuming piston 14 is fixed on the energy-consuming guide rod 7 to limit the maximum stroke of the energy-consuming upper sealing plate 5 and the energy-consuming lower sealing plate 6. The energy-consuming piston 14 is provided with multiple damping holes 15 for the damping material 11 to pass through. The space between the energy-consuming upper sealing plate 5 and the energy-consuming lower sealing plate 6 is filled with damping material 11.
[0007] Preferably, the spring 10 is a single, integral, annular spring.
[0008] Preferably, the springs 10 are distributed in multiples, uniformly distributed within the annular space.
[0009] Preferably, the damping holes 15 are evenly distributed on the energy-consuming piston 14.
[0010] Furthermore, the spring 10 is one of a steel helical spring, a disc spring, or a wave spring.
[0011] Preferably, it also includes an upper energy-consuming connecting cylinder 3, the upper end of the energy-consuming outer cylinder 4 is fixedly connected to the lower end of the upper energy-consuming connecting cylinder 3, and the upper energy-consuming connecting cylinder 3, the energy-consuming upper sealing plate 5, the energy-consuming outer cylinder 4 and the energy-consuming lower sealing plate 6 together form a fixed energy-consuming cylinder body that cannot undergo relative deformation.
[0012] Furthermore, the upper energy-consuming sealing plate 5 and the lower energy-consuming sealing plate 6 are respectively installed on the energy-consuming guide rods 7 on both sides of the energy-consuming piston 14, and the energy-consuming guide rods 7 and the fixed energy-consuming cylinder can move axially relative to each other.
[0013] A method for operating the built-in energy-dissipating anti-crushing vertical vibration isolation support described in any one of the above: When the support is in its initial state, the spring 10 is in a free state, and the energy-dissipating piston 14 abuts against the energy-dissipating lower sealing plate 6; when the support is installed and in working state, or when it needs to be pre-pressed according to the weight of the upper part after installation and is in a static pressure state, the spring 10 is compressed, the energy-dissipating piston 14 is disengaged from the energy-dissipating lower sealing plate 6, and is located in the middle of the energy-dissipating outer cylinder 4; when the upper structure causes external earthquakes or vibrations to cause pressure applied to the support relative to the static pressure... When the force decreases, the compression length of the support spring 10 decreases relative to the compression amount under static pressure, and the overall length of the spring 10 elongates. The upper connecting plate 1 drives the fixed energy-dissipating cylinder to move upward together. The energy-dissipating guide rod 7 is fixed to the lower connecting plate 2 and does not move. Relative movement occurs between the fixed energy-dissipating cylinder and the energy-dissipating guide rod 7. During the relative movement, the damping material 11 flows through the damping hole 15 on both sides of the energy-dissipating piston 14, and the flow resistance generated by the flow plays an energy-dissipating role. When the pressure applied to the support by the upper structure due to external earthquake or vibration is relative to the static pressure... When the pressure increases, the compression length of the support spring 10 increases relative to the compression amount under static pressure, and the overall length of the spring 10 shortens. The upper connecting plate 1 drives the fixed energy-dissipating cylinder to move downward together. The energy-dissipating guide rod 7 is fixed to the lower connecting plate 2 and does not move. Relative movement occurs between the fixed energy-dissipating cylinder and the energy-dissipating guide rod 7. During the relative movement, the damping material 11 flows through the damping hole 15 on both sides of the energy-dissipating piston 14. The flow resistance generated by the flow plays an energy-dissipating role. When the support changes from a compressed state to a tensile state and reaches the critical point, the overall deformation state of the support is the same as the initial state. When the spring 10 remains unchanged, the energy-dissipating lower sealing plate 6 abuts against the energy-dissipating piston 14, and the entire support is in a tensile-locked state, preventing the support from undergoing tensile deformation and thus preventing the support from lifting off and failing. When the compression deformation of the support caused by external earthquakes or vibrations reaches the design compression limit of the support, the energy-dissipating piston 14 abuts against the energy-dissipating upper sealing plate 5, and the end face of the upper extension cylinder 13 of the lower connecting plate 2 abuts against the lower surface of the upper connecting plate 1, so that the entire support is in a compression-locked state, preventing further compression deformation and thus preventing the support from crushing and failing.
[0014] To address several technical problems existing in the prior art, the following technical solution is adopted: including an upper connecting plate, a lower connecting plate, a lower limiting ring, a spring limiting plate, a spring, and a built-in energy dissipation system. The built-in energy dissipation system consists of a fixed energy dissipation cylinder composed of an upper energy dissipation connecting cylinder, an energy dissipation upper sealing plate, an energy dissipation outer cylinder, and an energy dissipation lower sealing plate, and an energy dissipation guide rod. The energy dissipation outer cylinder is filled with damping material.
[0015] The beneficial effects of this invention are as follows:
[0016] 1) The built-in energy dissipation system provides stable and efficient energy dissipation for the support, and the fixed energy dissipation cylinder of the built-in energy dissipation system can also limit the horizontal deformation of the support and fix the position of the spring; the spring can provide the support with stable load-bearing capacity and vibration isolation / vibration capability.
[0017] 2) When the support is in its initial state, the spring is in a free state, and the energy-dissipating piston abuts against the lower energy-dissipating end plate. When the support is installed and in working condition, or when it needs to be pre-pressed according to the weight of the upper part after installation and is in a static pressure state, the spring is compressed, the energy-dissipating piston separates from the lower energy-dissipating end plate, and is located in the middle of the outer energy-dissipating cylinder. When the pressure applied to the support by the upper structure due to external earthquakes or vibrations decreases relative to the static pressure, the compression length of the support spring decreases relative to the static pressure, the overall length of the spring elongates, the upper connecting plate drives the fixed energy-dissipating cylinder to move upward together, the energy-dissipating guide rod is fixed to the lower connecting plate and does not move, and relative movement occurs between the fixed energy-dissipating cylinder and the energy-dissipating guide rod. During the relative movement, the damping material flows through the damping holes on both sides of the energy-dissipating piston, and the flow resistance generated by the flow plays an energy-dissipating role. When the pressure applied to the support by the upper structure due to external earthquakes or vibrations increases relative to the static pressure, the compression length of the support spring increases. Compared to the increased compression under static pressure, the overall length of the spring shortens. The upper connecting plate drives the fixed energy-dissipating cylinder to move downwards together. The energy-dissipating guide rod is fixed to the lower connecting plate and does not move. Relative movement occurs between the fixed energy-dissipating cylinder and the energy-dissipating guide rod. During the relative movement, the damping material flows through the damping holes on both sides of the energy-dissipating piston. The flow resistance generated by the flow plays an energy-dissipating role. When the support transitions from a compressed state to a tensile state and reaches the critical point, the support is in its initial state. The spring does not deform, the lower energy-dissipating sealing plate abuts against the energy-dissipating piston, and the support is in a tensile-locked state, preventing the support from undergoing tensile deformation and preventing lift-off failure. When the compression deformation of the support due to external earthquakes or vibrations reaches the design compression limit state, the energy-dissipating piston abuts against the upper energy-dissipating sealing plate, and the upper cylindrical end face of the lower connecting plate abuts against the lower surface of the upper connecting plate, keeping the support in a compression-locked state and preventing further compression deformation, thus preventing crushing failure.
[0018] 3) All components in the built-in energy-dissipating anti-crushing vertical seismic isolation / vibration support can be mass-produced in the factory and assembled and fixed by threads or high-strength bolts, which facilitates maintenance and replacement.
[0019] 4) This invention utilizes a built-in energy-dissipating, anti-crushing vertical seismic isolation / vibration bearing to solve the problem of weak energy dissipation capacity of conventional bearings. Furthermore, the state-locked structural design prevents the bearings from lifting off and crushing, ensuring the safety of the superstructure under conditions exceeding design benchmarks.

[0032] Specifically, it also includes an upper energy-consuming connecting cylinder 3, the upper end of the energy-consuming outer cylinder 4 is fixedly connected to the lower end of the upper energy-consuming connecting cylinder 3, and the upper energy-consuming connecting cylinder 3, the energy-consuming upper sealing plate 5, the energy-consuming outer cylinder 4 and the energy-consuming lower sealing plate 6 together form a fixed energy-consuming cylinder body that cannot undergo relative deformation.
[0033] The upper energy-consuming sealing plate 5 and the lower energy-consuming sealing plate 6 are respectively installed on the energy-consuming guide rods 7 on both sides of the energy-consuming piston 14, and the energy-consuming guide rods 7 and the fixed energy-consuming cylinder can move axially relative to each other.
[0034] The upper end of the upper energy-consuming connecting cylinder 3 with the built-in energy-consuming system is fixedly connected to the upper connecting plate 1, and the lower end of the energy-consuming guide rod 7 is fixedly connected to the lower connecting plate 2. During the deformation of the support, the fixed energy-consuming cylinder and the energy-consuming guide rod 7 can move relative to each other.
[0035] The upper energy-consuming sealing plate 5 is fixedly connected to the inner wall of the upper end of the energy-consuming outer cylinder 4, and the lower energy-consuming sealing plate 6 is fixedly connected to the inner wall of the lower end of the energy-consuming outer cylinder 4.

[0039] The working method of this built-in energy-dissipating anti-collapse vertical vibration isolation support:
[0040] When the support is in the initial state, the spring 10 is in a free state, and the energy-consuming piston 14 abuts against the energy-consuming lower sealing plate 6.
[0041] When the support is installed and in working condition, or when it needs to be pre-pressed according to the weight of the upper part after installation and is in static pressure condition, the spring 10 is compressed, and the energy-consuming piston 14 is disengaged from the energy-consuming lower sealing plate 6 and is located in the middle of the energy-consuming outer cylinder 4. Figure 2 As shown.
[0042] When the pressure applied to the support by the superstructure decreases relative to the static pressure due to external earthquakes or vibrations, the compression length of the support spring 10 decreases relative to the static pressure, and the overall length of the spring 10 elongates.

Spring 10 does not deform, and the energy-dissipating lower sealing plate 6 abuts against the energy-dissipating piston 14. The entire support is in a tensile-locked state, preventing tensile deformation and thus preventing support lift-off failure. Figure 1 As shown.
