Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vibration isolation and buffer devices, and in particular to a main elastic vibration isolation and buffer device. Background Technology
[0002] Wire rope shock absorbers have softened nonlinear stiffness and good damping characteristics. They have a long service life, various installation methods, good buffering performance, and are easy to install. Vertical installation can also take into account lateral shear. They are suitable for various environments such as vibration reduction, vibration isolation, and impact resistance for various structures.
[0003] However, traditional wire rope vibration isolators have multi-directional large displacement elastic deformation capabilities, with maximum dynamic deformation reaching over 100mm. While this dynamic deformation capability is beneficial for resisting large impact deformation and reducing impact response, it also results in a large relative displacement between the two pairs of wire rope pressure plates, posing a potential risk of equipment collision for equipment supported by the wire rope vibration isolator.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a main elastic vibration isolation buffer device to improve the stability of the vibration isolation buffer device.
[0006] The technical solution of this utility model is as follows:
[0007] The main elastic vibration isolation and buffer device includes:
[0008] The cargo box has a first elastic element and a second elastic element installed inside.
[0009] A support column extends into the cargo box; the support column includes an enlarged section with an increased diameter;
[0010] The first clamping plate connects to the cargo box;
[0011] The second clamping plate connects to the support column extending from the cargo box;
[0012] A steel wire rope, one end of which is connected to the first clamping plate and the other end of which is connected to the second clamping plate;
[0013] The first elastic element and the second elastic element are arranged sequentially along the axial direction of the support column; the expanded diameter section is arranged between the first elastic element and the second elastic element; at least two steel wire ropes are provided, and all the steel wire ropes are arranged symmetrically along the axis of the support column.
[0014] A further technical solution is to provide a washer between the first elastic element and the second elastic element.
[0015] A further technical solution is that the first elastic member facing the second clamping plate and the second elastic member facing away from the second clamping plate are respectively provided with grooves.
[0016] A further technical solution is that the outer edge of the cargo box away from the second clamping plate is provided with a flange; the flange is provided parallel to the first clamping plate; the side of the flange closest to the second clamping plate contacts the first clamping plate; the first clamping plate is connected to the flange.
[0017] A further technical solution is that the first clamping plate includes a first lower clamping plate and a first upper clamping plate; one end of the wire rope extends between the first lower clamping plate and the first upper clamping plate.
[0018] A further technical solution is that the second clamping plate includes a second upper clamping plate and a second lower clamping plate; one end of the wire rope extends between the second upper clamping plate and the second lower clamping plate.
[0019] A further technical solution is that the second upper clamping plate and the second lower clamping plate are respectively provided with second screw holes and connected by second fastening screws.
[0020] A further technical solution is that the support column includes a reduced diameter section; the reduced diameter section is provided with external threads; and a third threaded hole is opened on the second clamping plate to thread the reduced diameter section.

[0022] A further technical solution is that a connecting hole is formed on the connecting plate; the axis of the connecting hole is parallel to the axis of the support column.
[0023] The beneficial technical effects of this utility model are as follows:
[0024] (1) The main elastic vibration isolation buffer device of this utility model is provided with a first clamping plate and a second clamping plate, and a steel wire rope is provided between the first clamping plate and the second clamping plate. When the second clamping plate is subjected to compression, shear or tension load, the steel wire rope bends and deforms. The relative sliding between each fine steel wire in the deformed steel wire rope generates frictional damping to reduce vibration, isolate vibration and resist impact. In addition, the main elastic vibration isolation buffer device is also provided with a support column, which is connected to both ends of the steel wire rope and is clamped and fixed by the first elastic element and the second elastic element. When the main elastic vibration isolation buffer device is subjected to a large impact force, the loading box restricts the axial and radial movement range of the support column, thereby limiting the relative displacement between the first clamping plate and the second clamping plate and reducing the risk of equipment collision due to excessive deformation. At the same time, it also limits the deformation of the steel wire rope and effectively extends its service life.
[0025] (2) Furthermore, a washer is provided between the first elastic member and the second elastic member. The washer limits the distance between the first elastic member and the second elastic member, thereby limiting the range of movement of the support column when the first elastic member and the second elastic member do not restrict the movement of the support column. This improves the flexibility of the main elastic vibration isolation buffer device.
[0026] (3) Further, the first elastic member and the second elastic member are respectively provided with grooves. The grooves provide a large deformation space for the first elastic member and the second elastic member, so that the first elastic member and the second elastic member can deform and provide restoring force when under pressure.

[0033] Figure 1 A vertical cross-sectional schematic diagram of a main elastic vibration isolation buffer device according to an embodiment of the present disclosure is shown. Figure 2 A top view of a primary elastic vibration damping device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The main elastic vibration isolation and buffer device includes a loading box 6, inside which are installed a first elastic element 61 and a second elastic element 63. The first elastic element 61 and the second elastic element 63 can be made of metal-rubber. Metal-rubber provides nonlinear stiffness, high load-bearing capacity, and fatigue resistance, effectively reducing vibration and offering high reliability. A support column 5 extends into the loading box 6. The support column 5 includes an expanded diameter section 52. A first clamping plate 2 connects to the loading box 6. A second clamping plate 4 connects to the support column 5 extending out of the loading box 6. A steel wire rope 3 connects one end to the first clamping plate 2 and the other end to the second clamping plate 4. The steel wire rope 3 is formed by multiple steel wires twisted and turned, and is made of stainless steel. When the second clamping plate 4 is subjected to compression, shear, or tensile loads, the steel wire rope 3 bends and deforms. The relative slippage between each fine steel wire within the deformed steel wire rope 3 generates frictional damping, thus reducing vibration, isolating vibration, and resisting impact.
[0034] Along the axial direction of the support column 5, the first elastic element 61 and the second elastic element 63 are sequentially arranged. The expanded diameter section 52 is positioned between the first elastic element 61 and the second elastic element 63. When the main elastic vibration isolation buffer device experiences a large impact force, the loading box 6 restricts the axial and radial movement range of the support column 5, thereby limiting the relative displacement between the first clamping plate 2 and the second clamping plate 4, reducing the risk of equipment collision due to excessive deformation. It also limits the deformation of the wire rope 3, effectively extending its service life. At least two wire ropes 3 are provided, and all wire ropes 3 are symmetrically arranged along the axis of the support column 5 to withstand the stresses generated in various directions during deformation between the second clamping plate 4 and the first clamping plate 2.
[0035] In some embodiments, the first clamping plate 2 and the second clamping plate 4 are disc-shaped. The steel wire rope 3 between the first clamping plate 2 and the second clamping plate 4 is also evenly arranged around the axis of the support column 5 to resist stress in all directions.
[0036] In other embodiments, adjacent wire ropes 3 are arranged in a staggered manner. When the wire ropes 3 deform, they compress against each other, increasing the friction provided by the wire ropes 3.
[0037] Please refer to Figure 1 The first clamping plate 2 includes a first lower clamping plate 21 and a first upper clamping plate 22. One end of the wire rope 3 extends between the first lower clamping plate 21 and the first upper clamping plate 22 and is clamped and fixed. In some embodiments, a clamp (not shown in the figure) may also be provided at the end of the wire rope 3. A groove (not shown in the figure) is provided between the first lower clamping plate 21 and the first upper clamping plate 22 for the clamp to engage, thereby enhancing the connection strength between the first clamping plate 2 and the wire rope 3.
[0038] Preferably, it also includes a connecting plate 1. The cargo box 6 and the first clamping plate 2 are disposed on the connecting plate 1. A connecting hole 11 is provided on the connecting plate 1, and the axis of the connecting hole 11 is parallel to the axis of the support column 5, so as to facilitate fixing the connecting plate 1 on the mounting plane.
[0039] More preferably, the first clamping plate 2 and the connecting plate 1 have corresponding first screw holes 24 and are connected by first fastening screws 23. A flange 64 is provided on the outer edge of the storage box 6 away from the second clamping plate 4. The flange 64 is parallel to the first clamping plate 2. The side of the flange 64 closest to the second clamping plate 4 contacts the first clamping plate 2. The first clamping plate 2 is connected to the flange 64. That is, the flange 64 is clamped between the first clamping plate 2 and the connecting plate 1, increasing the connection strength between the first clamping plate 2, the connecting plate 1, and the storage box 6.
[0040] Please refer to Figure 1The second clamping plate 4 includes a second upper clamping plate 41 and a second lower clamping plate 42. One end of the wire rope 3 extends between the second upper clamping plate 41 and the second lower clamping plate 42 and is clamped and fixed. In some embodiments, a clamp (not shown in the figure) may also be provided at the end of the wire rope 3. A groove (not shown in the figure) is provided between the second lower clamping plate 42 and the second upper clamping plate 41 for the clamp to engage, thereby enhancing the connection strength between the second clamping plate 4 and the wire rope 3.
[0041] Preferably, the second upper clamping plate 41 and the second lower clamping plate 42 are respectively provided with second screw holes 44, and are connected by second fastening screws 43. The threaded connection can provide the second upper clamping plate 41 and the second lower clamping plate 42 with a huge clamping force to ensure the connection strength between the second clamping plate 4 and the wire rope 3. Moreover, the threaded connection is easy to disassemble and assemble, and facilitates the replacement and maintenance of the wire rope 3.
[0042] More preferably, the support column 5 includes a reduced-diameter section 51. External threads are provided on the reduced-diameter section 51. A third threaded hole 45 is provided on the second clamping plate 4 to threadedly connect to the reduced-diameter section 51. The threaded connection is convenient and quick, facilitating assembly and disassembly. Simultaneously, the threaded connection has high strength, ensuring the connection strength between the second clamping plate 4 and the support column 5. A step 511 is formed at the abrupt decrease in diameter of the reduced-diameter section 51. The step 511 can support the second clamping plate 4 and quickly position it.
[0043] Please refer to Figure 1 A washer 62 is provided between the first elastic member 61 and the second elastic member 63. The washer 62 limits the distance between the first elastic member 61 and the second elastic member 63, thereby limiting the range of movement of the support column 5 when the first elastic member 61 and the second elastic member 63 do not restrict the movement of the support column 5. This improves the flexibility of the main elastic vibration isolation buffer device.
[0044] More preferably, the first elastic member 61 facing the second clamping plate 4 and the second elastic member 63 facing away from the second clamping plate 4 are respectively provided with grooves. The grooves provide a large deformation space for the first elastic member 61 and the second elastic member 63, allowing the first elastic member 61 and the second elastic member 63 to deform and provide restoring force when under pressure.
[0045] The specific workflow of this utility model is as follows:
[0046] When the second clamping plate 4 is subjected to compression, shear, or tensile loads, the wire rope 3 bends and deforms. The relative slippage between each fine wire within the deformed wire rope 3 generates frictional damping, thus reducing vibration, isolating vibration, and resisting impact. During this process, the first clamping plate 2 and the second clamping plate 4 move relative to each other, and the support column 5 and the first elastic element 61, as well as the support column 5 and the second elastic element 63, mutually compress and interfere with each other, thereby limiting the range of relative movement between the first clamping plate 2 and the second clamping plate 4.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
