Description

Technical Field

[0001] The invention relates to the technical field of supports, and in particular to a multi-directional vibration reduction and isolation support. Background Art

[0002] With the acceleration of urbanization, the expansion of rail transit systems and the increase in urban construction activities, vibration problems have gradually become an important part of urban life. These vibrations come not only from daily traffic, but also from construction site operations, which have a negative impact on the structural integrity of surrounding buildings and the quality of life of residents inside. More seriously, the severe vibrations caused by earthquakes may cause damage to buildings, cause huge economic losses and threaten people's lives. In order to deal with these problems, the use of effective vibration isolation technology has become an important means to protect buildings and their users. Practice has shown that by implementing appropriate vibration isolation measures, the adverse effects of vibrations caused by various reasons can be significantly reduced, thereby ensuring the safety and stability of buildings and improving the comfort of residents.

[0003] At present, vibration reduction and isolation technology has been widely used in the world, and different types of vibration reduction and isolation devices have been promoted and used. Existing vibration reduction and isolation technologies have been extensively studied in passive vibration isolation, active vibration isolation, damping vibration absorption, avoiding resonance areas, etc., and some have achieved technological breakthroughs. In terms of material application, considering the wide application and economic benefits of the bearings, the existing bearings are mostly made of rubber, steel, and concrete. However, in recent years, more new materials have also been gradually applied to vibration reduction, such as alloys, viscous damping fluids, oily damping fluids, nanomaterials, foam materials, and memory alloys.

[0033] According to another aspect of the present invention, a method for using a multi-directional vibration reduction and isolation support is provided, comprising the following steps:

[0034] S01: Insert the plug column 13 into the connection hole 6 of the connection column 3, and the limit seat 14 cooperates with the recovery layer 15 and the buffer seat 16 to limit the column 8, and then assemble the upper support 2 and the lower support 1 with the building through the bolts in the installation hole 4;

[0035] S02: When assembling the energy dissipation mechanism, by pulling the pull plate 24, the positioning rod 26 slides on the cross plate 21, the spring 25 is stretched by force to store potential energy, and the mounting block 9 is inserted into the mounting groove 5, and the guide plate 23 and the guide groove 10 are matched to ensure that no deviation occurs during the plugging process.

[0036] S03: Then, the return pipe 27 and the inlet pipe 28 are connected and fixed to the corresponding connecting pipe 20 through the connector 29 to ensure firmness and sealing effect;

[0037] S04: When vibration occurs, the buffer sleeve 12 outside the plug-in column 13, the buffer pad 7 at the top of the connecting column 3, and the recovery layer 15 and the buffer seat 16 in the limit seat 14 can all be used for buffering and energy dissipation. At the same time, the movable plate 1 30 on the extension rod 18 slides in the energy dissipation cavity 32, and cooperates with the sealing ring 1 31 to consume part of the kinetic energy through internal friction, and then cooperates with the return pipe 27 and the liquid inlet pipe 28 to slide with the movable plate 2 33 and the sealing ring 2 34, and buffer and energy dissipate again, thereby ensuring stability and safety, and multi-directional energy dissipation and shock absorption;

[0038] S05: When the energy dissipation mechanism needs to be disassembled for inspection or replacement, close the valves on the return pipe 27 and the inlet pipe 28, and then unscrew the connector 29. Then, by pulling the pull plate 24, the positioning rod 26 is moved out of the positioning hole 11, the fixed magnetic attraction 22 is separated by force, and the spring 25 is stretched to store potential energy, and the limit on the mounting block 9 is lost. At this time, the mounting block 9 can be taken out of the mounting groove 5, and the energy dissipation mechanism can be removed to complete the disassembly, which is convenient for subsequent inspection or disassembly operations.

At the same time, the provided buffer pads 7 during use can conveniently realize multi-directional energy dissipation and shock absorption, and can assist in buffering and energy dissipation. In conjunction with the energy dissipation mechanism, the vibration generated during earthquakes can be converted into sliding kinetic energy. The liquid can disperse and absorb this part of the energy through internal flow, thereby reducing the vibration transmitted to the supporting structure, and at the same time consume it through internal friction to achieve effective shock absorption. The energy dissipation mechanism can be conveniently installed and fixed through the provided installation mechanism. The installation is screw-free and can be completed without the aid of tools, which facilitates assembly and disassembly operations. At the same time, it ensures firmness during use and the effect of energy dissipation and shock absorption. When a failure occurs and needs to be repaired or replaced, it can be easily and quickly disassembled, and it is convenient to disassemble and replace separately, which is flexible and convenient.
