Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of vibration isolation and separation, and particularly relates to a vibration isolation device, in particular to a vibration isolation device with an ultrathin structure height. BACKGROUND
[0002] In recent years, with the improvement of people's environmental protection consciousness and the upgrading of environmental protection laws and regulations, higher requirements are put forward for vibration and noise control in production and life, especially for building structures susceptible to vibration and noise interference, and fields such as large impact equipment, large rotary equipment, which are prone to vibration and noise problems. How to isolate vibration has become an important problem that must be considered in the process of project establishment, design and construction. In order to control vibration and noise problems, researchers have designed various large spring vibration isolation devices (also known as spring isolators, of which spiral steel spring isolators are the most common). For example, the multi-directional damping spring isolator disclosed in the utility model patent with the patent authorization announcement number CN204419974U, and the heavy spring isolator for an offshore platform disclosed in the utility model patent with the patent authorization announcement number CN220956576U, and so on. In such large and heavy spring vibration isolation devices, in order to improve the carrying capacity, multiple springs are usually arranged in parallel, and in order to facilitate installation, jacking and leveling, the spring group needs to be pre-tightened using a pre-tightening structure. In the existing spring vibration isolation device, the upper shell or / and the lower shell is arranged as a box-shaped structure with a certain height, so as to ensure sufficient operation space during pre-tightening adjustment and good bending resistance. However, such spring vibration isolation devices with a box-shaped structure generally have a larger height dimension, which requires a larger space, seriously affecting the applicability of the spring vibration isolation device, and cannot be applied to some height-limited working conditions, limiting the application range of the spring vibration isolation device.
[0003] In summary, there is an urgent need in the market to provide a spring vibration isolation device with smaller space occupation, better applicability and convenient jacking. UTILITY MODEL CONTENT
[0004] The utility model aims at overcoming the above-mentioned defects, and provides an ultrathin vibration isolation device with a jacking space, which has a more compact structure, is more convenient to jack, and has better applicability and practicality.
[0005] The utility model discloses a super -thin vibration isolation device of jacking space is realized, including casing and elastic element, the casing includes upper casing and lower casing, and the elastic element is located between upper casing and lower casing, and leaves the working clearance between upper casing and lower casing, and the upper casing or / and lower casing is the basin formula structure, the basin formula structure includes basin bottom plate and basin apron, and the included angle of basin apron and basin bottom plate is 90 ° - 120 °, and the basin apron is fixedly connected or integrative with the basin bottom plate, and the elastic element is supported on the inner surface of basin bottom plate, the outside of basin apron opening end is provided with the jacking pre -tightening support plate parallel to basin bottom plate, and at least two outer reinforcing rib plates are arranged at interval between jacking pre -tightening support plate and basin apron, and the groove formula structure surrounded by jacking pre -tightening support plate, basin apron and outer reinforcing rib plate constitutes the jacking space, and pre -tightening connecting structure is arranged on jacking pre -tightening support plate.
[0006] The specific shape of the basin formula structure is various, preferably, the contour shape surrounded by the basin apron in the cross section of the basin formula structure is circular, square, rectangular or other polygon with even number of sides, which is symmetrically arranged along the median plane. For the basin formula structure with such shape, preferably, the groove formula structure constituting the jacking space is symmetrically arranged on at least two sides of the basin formula structure.
[0007] In order to improve the bending resistance of the casing, inner reinforcing rib plates can also be arranged in the basin formula structure of the upper casing or / and the lower casing. The arrangement of the inner reinforcing rib plates can be various, typical technical solutions include: (1) the inner reinforcing rib plates are arranged in parallel or perpendicular to the basin apron, and the elastic elements are arranged in the lattice surrounded by at least part of the inner reinforcing rib plates and the basin apron or / and the lattice surrounded by at least part of the inner reinforcing rib plates; (2) the inner reinforcing rib plates are arranged radially from the middle of the basin formula structure to the basin apron, and the elastic elements are arranged in the lattice surrounded by at least part of the inner reinforcing rib plates and the basin apron; (3) the inner reinforcing rib plates include centripetal reinforcing rib and concentric reinforcing rib with the same contour shape as the basin apron, the two ends of the centripetal reinforcing rib are fixedly connected with the adjacent concentric reinforcing rib, or the two ends of the centripetal reinforcing rib are connected with the basin apron and the concentric reinforcing rib respectively, and the elastic elements are arranged in the lattice surrounded by at least part of the inner reinforcing rib plates and the basin apron or / and the lattice surrounded by at least part of the inner reinforcing rib plates; (4) the inner reinforcing rib plates are arranged in honeycomb shape, and the elastic elements are arranged in the lattice surrounded by at least part of the inner reinforcing rib plates and the basin apron or / and the lattice surrounded by at least part of the inner reinforcing rib plates. These technical solutions can also achieve good technical effects, and can be designed and selected according to needs in practice. In addition, in order to better improve the overall strength of the structure, preferably, at least part of the inner reinforcing rib plates and the outer reinforcing rib plates are correspondingly arranged on both sides of the basin apron, or at least part of the inner reinforcing rib plates and the outer reinforcing rib plates are integrally arranged.
[0008] The pre-tightening connecting structure comprises a pre-tightening connecting through hole or a pre-tightening connecting piece.
[0009] In order to improve the anti-seismic capability of the ultra-thin vibration isolation device with a jacking space, the upper shell or the lower shell can be further provided with a slide plate pair, a laminated rubber support or a friction pendulum support in series connection.
[0010] In the utility model, a damping element is arranged between the upper shell and the lower shell, or a damping material is arranged in the basin structure as the damping element, and the elastic element is partially arranged in the damping material.
[0011] In order to facilitate connection with the surrounding structure, mounting through holes for connecting with external structures can be arranged on the upper shell and the lower shell.
[0012] Since the pre-tightening or jacking isolation device is in the pre-tightening or jacking state, the jacking pre-tightening support plate will bear a large vertical load, even greater than the vertical load in the rated working state, and the counterforce of the elastic element will form a large bending moment on the shell, so the shell in the prior art generally adopts a closed box structure to resist bending, and the elastic element is located outside the box structure, specifically between the upper and lower shells, occupying a large height space. To solve the above problems, the ultra-thin isolation device with jacking space is provided, the upper shell or / and the lower shell is provided with a basin structure, the jacking space and the pre-tightening connecting space are transferred to the groove structure on both sides of the basin structure, and part of the elastic element is hidden in the basin structure, so that the overall height of the product is effectively reduced; in addition, the inner reinforcing rib plate, the concentric reinforcing rib and the centripetal reinforcing rib are additionally arranged in the basin structure, and the outer reinforcing rib plate is additionally arranged outside the basin structure, so that the bending resistance of the upper shell or / and the lower shell is ensured without increasing the overall height, and the problem of large overall height and large space occupation of the traditional isolation device caused by the additional box structure for increasing the bending resistance is avoided.
[0013] It is particularly pointed out that, first, after the slide plate pair, the laminated rubber support or the friction pendulum support are arranged in series on the upper shell or the lower shell, the ultra-thin isolation device with jacking space not only has good isolation performance but also has good anti-seismic performance, and can realize the technical effect of vibration and earthquake control; secondly, the basin skirt plate of the basin structure is a solid structure for forming the jacking space, and in the working process, it always exists as a force structure as an important part of the shell, so the basin skirt plate must be able to bear the external load applied by the isolation and vibration reduction object, which is essentially different from the thin barrier plate (for example, the thickness of the dustproof plate is generally less than 5mm for the bearing capacity of more than 40 tons) arranged in the traditional isolation device only for shielding rainwater, oil stains, dust and other foreign matters; thirdly, since the working gap between the upper shell and the lower shell is much smaller than the distance between the upper shell and the lower shell in the traditional isolation device, an elastic sealing element can be additionally arranged between the upper shell and the lower shell, compared with the sealing ring used in the traditional isolator, the elastic sealing element can effectively prevent foreign matters from entering the ultra-thin isolation device with jacking space, has better protection effect, and has better reliability and durability. Of course, the vertical stiffness of the elastic sealing element should be much smaller than the vertical stiffness of the elastic element, and generally the vertical stiffness of the elastic sealing element is not more than one tenth of the vertical stiffness of the elastic element, so that the performance of the elastic element is not adversely affected.
[0014] In summary, the ultra-thin isolation device with jacking space has the advantages of simple and compact structure, high space utilization rate, small height space occupation, strong bearing capacity and good applicability, and can be widely applied in isolation and vibration reduction engineering in the fields of building structures, large impact equipment and large rotary equipment, and has a very broad application prospect.

[0034] Example one
[0035] As Figure 1 And Figure 2 The utility model discloses an ultrathin vibration isolation device with jacking space, including shell and elastic element 1, and the elastic element 1 is specifically spiral steel spring, and the shell includes upper shell 9 and lower shell 2, and the upper shell adopts basin formula structure, and the contour shape that the first basin apron surrounds in the cross section of basin formula structure is circular, in order to distinguish and explain the connection relation, the basin formula structure of constituting the upper shell is called first basin formula structure, the first basin formula structure includes first basin bottom plate 3 and the first basin apron 4 perpendicular to first basin bottom plate 3, and the first basin apron 4 is connected with first basin bottom plate 3 and is fixed by welding, considering the need of bending resistance, and the lower shell 2 is made of the steel plate thicker than first basin bottom plate 3, the elastic element 1 is located between the upper shell and lower shell 2, and the elastic element 1 is supported on the inner surface of first basin bottom plate 3, and the working clearance A is left between the upper shell and lower shell 2, and the first basin bottom plate 3 of upper shell is fixed with the centering positioning piece 6 of elastic element respectively on lower shell 2, and the centering positioning piece 6 is specifically a section of steel pipe, the first jacking pre-tightening support plate 5 parallel to the first basin bottom plate is set up on the open end outside of the first basin apron 4 of upper shell, eight outer reinforcing rib plates 8 are set apart in the ring direction between the first jacking pre-tightening support plate 5 and the first basin apron 4, and the groove formula structure of the first jacking pre-tightening support plate 5, the first basin apron 4 and outer reinforcing rib plate 8 constitutes jacking space B, pre-tightening connection structure is set up on the first jacking pre-tightening support plate 5, and the pre-tightening connection structure is specifically the pre-tightening connection through -hole set up on the first jacking pre-tightening support plate 5, and the pre-tightening connecting piece 7 is fixed on the lower shell, and the upper shell and lower shell are connected together by pre-tightening connecting piece 7 through pre-tightening connection through -hole.
[0036] Generally, in use, at least four ultra-thin vibration isolation devices with jacking space of the utility model are supported below the vibration isolation object. When jacking, two jacks are symmetrically placed in the two jacking spaces B on both sides of one of the ultra-thin vibration isolation devices with jacking space of the utility model, the jacking force acts upward on the bottom of the vibration isolation object, and the other end of the jack acts downward on the jacking pre-tightening support plate 5, so that the vibration isolation object can be lifted or the ultra-thin vibration isolation device with jacking space of the utility model can be compressed to make it shorter. At this time, the height adjustment pad plate with appropriate thickness is added between the upper shell and the vibration isolation object to complete the height adjustment and leveling of the vibration isolation object. In this process, the jacking force of the jack and the elastic force of the elastic element jointly act on the upper shell to generate bending moment. In addition, the supported vibration isolation object is supported by other ultra-thin vibration isolation devices with jacking space of the utility model or replaced by additional jacks (or temporary buttress) under the premise that the ultra-thin vibration isolation device with jacking space of the utility model is used. The pre-tightening connecting piece 7 can be used to lock the ultra-thin vibration isolation device with jacking space, so that it can be removed for maintenance or replacement. After locking, the ultra-thin vibration isolation device with jacking space enters the pre-tightening state, and the overall height is further compressed. The pre-tightening force acts between the jacking pre-tightening support plate 5 and the lower shell 2 through the pre-tightening connecting piece 7. At this time, the pre-tightening force of the four pre-tightening connecting pieces 7 and the elastic force of the elastic element 1 form a balance, and bending moment is generated on the upper shell and the lower shell.
[0037] The ultra-thin vibration isolation device with jacking space of the utility model effectively reduces the overall height of the product by adopting the upper shell with a basin structure, transferring the jacking space and the pre-tightening connection space to the groove structure on both sides of the basin structure, and hiding part of the elastic element height in the basin structure. In addition, by adding an external reinforcing rib plate outside the basin structure, the structural bending resistance of the upper shell in the pre-tightening or jacking state is ensured without additional increase in the overall height, avoiding the problem of large overall height and large space occupation of the traditional vibration isolation device using box structure.
[0038] It is particularly pointed out that the first basin skirt plate of the first basin structure in the technical scheme of the utility model is a solid structure constituting the jacking space, and in the working process, it always exists as a force structure as an important part of the shell, so the first basin skirt plate must be able to bear the external load applied by the isolation and damping object, which is essentially different from the thin shielding plate (for example, the thickness of the dustproof plate is generally less than 5mm for the bearing capacity of more than 40 tons) arranged in the traditional isolation device only for shielding rainwater, oil stains, dust and other foreign matters. In addition, the pre-tightening connecting structure in the ultra-thin isolation device with the jacking space of the utility model is a functional structure for facilitating transportation and installation. After the ultra-thin isolation device with the jacking space of the utility model is installed between the structure to be isolated and damped and the foundation, the pre-tightening connecting piece can be loosened or even removed, which can be selected according to the engineering needs in practical application. This is applicable to all embodiments of the utility model and is described herein.
[0039] In addition, it should be noted that in this example, a helical steel spring is used as an elastic element, and in actual application, various elastic elements can be used in the utility model, including metal disc springs, rubber-metal composite springs, rubber springs, polyurethane springs or polyurethane microcellular foam elastic blocks, etc., which can also achieve good technical effects. In particular, many elastic elements such as rubber springs and polyurethane springs also have good damping performance, so they can be used as elastic elements and damping elements at the same time. Therefore, the damping element and the elastic element can be integrated in the utility model. In addition, according to the actual needs of the project, the specific number of elastic elements can be one, two, three, five or even more, which can be designed according to the needs of the project in practice. Thirdly, in this example, the first basin skirt plate 4 is arranged perpendicular to the first basin bottom plate 3, and in actual application, the included angle between the first basin skirt plate and the first basin bottom plate can be selected within the range of 90°-120°, which can achieve good results. Fourthly, in this example, eight outer reinforcing rib plates are arranged between the first jacking pre-tightening support plate and the first basin skirt plate, and in actual application, the number of outer reinforcing rib plates is at least two, and the specific number can be designed and selected according to the actual needs of the product. These are simple changes based on the technical principles of the utility model, and are within the scope of protection required by the utility model.

[0044] Embodiment three
[0045] As Figure 5 And Figure 6The utility model discloses a super -thin vibration isolation device of jacking space is equipped with, and the difference with embodiment two is that the upper casing and lower casing all adopt basin formula structure, wherein the first basin formula structure of constituting the upper casing is by the first basin apron 4 and first basin bottom plate 3 welding fixed and becomes, and the first basin apron 4 of the upper casing fixedly set parallel to the first basin bottom plate's first jacking pre -tightening support plate 5 of opening end outside, the first jacking pre -tightening support plate 5 and the first basin apron 4 between intervally set up outer stiffened rib plate 8, and the groove formula structure of the first jacking pre -tightening support plate 5, the first basin apron 4 and outer stiffened rib plate 8 enclose constitutes jacking space B;The second basin formula structure of constituting the lower casing is by the second basin apron 11 and second basin bottom plate 10 welding fixed and becomes, and the second basin apron 11 of the lower casing fixedly set parallel to the second basin apron's second jacking pre -tightening support plate 12 of opening end outside, the second jacking pre -tightening support plate 12 and the second basin apron 11 between intervally set up outer stiffened rib plate 8, and the groove formula structure of the second jacking pre -tightening support plate 12, the second basin apron 11 and outer stiffened rib plate 8 enclose also constitutes jacking space B;In addition, the groove formula structure of constituting jacking space is arranged on both sides of the center of the first basin formula structure and the second basin formula structure symmetry, and still be provided with inner stiffened rib plate 14 in the first basin formula structure and the second basin formula structure, the inner stiffened rib plate 14 in the first basin formula structure is by the first basin bottom plate 3 middle part to the first basin apron 4 radial arrangement, corresponding, the inner stiffened rib plate 14 in the second basin formula structure is by the second basin bottom plate 10 middle part to the second basin apron 11 radial arrangement, wherein, the upper part of elastic element 1 is arranged in the lattice of the inner stiffened rib plate 14 and the first basin apron 4, and the lower part of elastic element 1 is arranged in the lattice of the inner stiffened rib plate 14 and the second basin apron 11, and the inner stiffened rib plate 14 and outer stiffened rib plate 8 are correspondingly set up on both sides of the first basin apron 4 and the second basin apron 11;In addition, the centering positioning member is specifically the positioning column that is fixedly set up on the upper casing and the lower casing correspondingly;Fourth, the damping element 13 set up in the second basin formula structure is specifically polyurethane solid damping material, and elastic element 1 is partially placed in the polyurethane solid damping material;Fifth, the pre -tightening connecting structure is the pre -tightening connecting through -hole set up on the first jacking pre -tightening support plate 5 and the second jacking pre -tightening support plate 12, and the upper casing and the lower casing are connected together by pre -tightening connecting piece 7 through the pre -tightening connecting through -hole.
[0046] Compared with Example Two, in the technical solution described in this example, since the upper shell and the lower shell both adopt the basin type structure, the jacking space B below the second jacking pre-tightening plate 12 can be used for jacking, the jacking space B above the first jacking pre-tightening plate 5 can be used for jacking, or both can be used for jacking at the same time, which is more flexible and convenient. In addition, since the inner reinforcing rib plate 14 is additionally arranged in the basin type structure, the bending resistance and the load bearing capacity of the upper shell and the lower shell can be greatly improved, which provides reliable technical support for realizing a large load bearing vibration isolation device. It should be noted that in the technical solution described in this example, the inner reinforcing rib plate and the outer reinforcing rib plate can also be integrally arranged, and assembly notches are arranged on the first basin skirt plate and the second basin skirt plate. The integrally arranged inner reinforcing rib plate and the outer reinforcing rib plate are cross fitted with the assembly notches on the first basin skirt plate or the second basin skirt plate, and are welded and fixedly connected to form an integral body.

They are not described one by one in the drawings and are within the protection scope of the utility model.
[0048] Example Four
[0049] As shown in Figure 7 and Figure 8 The ultra-thin vibration isolation device with a jacking space of the utility model has the difference from Example Three that the inner reinforcing rib plate in the first basin type structure comprises a centripetal reinforcing rib 16 and a concentric reinforcing rib 15 which has the same contour shape as the first basin skirt plate 4, the two ends of the centripetal reinforcing rib 16 are connected with the first basin skirt plate 4 and the concentric reinforcing rib 15 respectively, the same structure is also adopted in the second basin type structure, and correspondingly, the upper part of the elastic element 1 is arranged in the lattice surrounded by the inner reinforcing rib plate and the first basin skirt plate, and the lower part of the elastic element 1 is arranged in the lattice surrounded by the inner reinforcing rib plate and the second basin skirt plate. In addition, a damping element 13 is arranged between the first basin type structure and the second basin type structure, and the damping element 13 is specifically a viscous damper, and the viscous damper is arranged on the inner side of the concentric reinforcing rib. In addition, the elastic sealing element 17 is also included, and the elastic sealing element 17 is arranged in the working gap between the upper shell and the lower shell.
[0050] Compared with example three, the inner reinforcing rib plate in the example is composed of concentric reinforcing ribs and centripetal reinforcing ribs, which is beneficial to improve the bending resistance and load capacity of the upper shell and the lower shell for large-sized products. Since the working gap between the upper shell and the lower shell is much smaller than the distance between the upper shell and the lower shell in the traditional vibration isolation device, the elastic sealing element added between the upper shell and the lower shell in the technical solution in the example can effectively prevent foreign matters from entering the ultrathin vibration isolation device with a jacking space, and has better protection effect, better reliability and durability. In particular, if the elastic sealing element is bonded by adhesive or is completely sealed by structural adhesive, a full waterproof structure can be formed, and the lower shell can be kept from being immersed in water and the product performance can be kept from being affected when the product is immersed in water for a short time, which is more safe and reliable. Of course, the vertical stiffness of the elastic sealing element should be much smaller than the vertical stiffness of the elastic element, and generally the vertical stiffness of the elastic sealing element is not more than one tenth of the vertical stiffness of the elastic element, so that the performance of the elastic element is basically not adversely affected.
[0051] Based on the technical principle of the example, the damping element in the utility model can be a small hole throttling damper, an eddy current damper, an elastic rubber damper or an elastic polyurethane damper, in addition to a viscous damper. In addition, only one concentric reinforcing rib is provided in the example, and for large-sized products, a plurality of concentric reinforcing ribs can be provided, and in this case, part of the centripetal reinforcing ribs are connected to the basin skirt plate and the concentric reinforcing rib at both ends, and the other part of the centripetal reinforcing ribs are fixedly connected to the adjacent concentric reinforcing rib at both ends. In addition, based on the technical principle recorded in example three, the elastic element 1 can be arranged in the grid surrounded by the part of the inner reinforcing rib plate and the first basin skirt plate (equivalent to the grid surrounded by the part of the inner reinforcing rib plate and the second basin skirt plate). These are simple changes based on the technical principle of the utility model, which are only described in words and not attached to the drawings, and are within the protection scope of the utility model.
[0052] Example five
[0053] As Figure 9The ultra-thin vibration isolation device with lifting space shown in this utility model differs from Embodiment 4 in that liquid damping material can be set as damping element 13 in the second basin-shaped structure of the lower shell, saving space inside the concentric reinforcing rib 15 to add elastic element 1; in addition, in the first basin-shaped structure of the upper shell, the first basin skirt plate 4, the first basin bottom plate 3, the first lifting pre-tightening support plate 5, the concentric reinforcing rib 15 and the radial reinforcing rib 16 are all integrally cast, and then the outer reinforcing rib plate 8 is welded and fixed to the first basin skirt plate 4 and the first lifting pre-tightening support plate 5. The second basin-shaped structure of the lower shell also adopts the same structure. In order to facilitate demolding during casting, the included angle between the first basin skirt plate and the first basin bottom plate is 120°, and the included angle between the second basin skirt plate and the second basin bottom plate is also 120°.
[0054] Compared to Embodiment 4, the technical solution described in this example incorporates more elastic elements, which helps increase the product's load-bearing capacity while maintaining the original dimensions. Furthermore, the integrated casting manufacturing method for both the upper and lower shells helps reduce processing costs and enhances the product's market competitiveness. Additionally, the angles between the first basin skirt plate and the first basin base plate, as well as the angles between the second basin skirt plate and the second basin base plate, can be designed and selected within the range of 90°-120° as needed, achieving excellent technical results.

[0057] The first basin skirt plate 4 in the cross section of the first basin structure of the upper shell has a rectangular outline shape, the first basin skirt plate 4 and the first basin bottom plate 3 are arranged perpendicularly to each other, the second basin skirt plate 11 in the cross section of the second basin structure of the lower shell also has a rectangular outline shape, the second basin skirt plate 11 and the second basin bottom plate 10 are arranged perpendicularly to each other; in the upper shell, the groove structure constituting the jacking space B is symmetrically arranged on both sides of the first basin structure, correspondingly, in the lower shell, the groove structure constituting the jacking space B is symmetrically arranged on both sides of the second basin structure; in the upper shell, the inner reinforcing rib plate 8 is arranged in parallel or perpendicularly to the first basin skirt plate 4, correspondingly, in the lower shell, the inner reinforcing rib plate 8 is arranged in parallel or perpendicularly to the second basin skirt plate 11, correspondingly, the upper part of the elastic element 1 is arranged in the grid formed by the inner reinforcing rib plate and the first basin skirt plate, and the lower part of the elastic element 1 is arranged in the grid formed by the inner reinforcing rib plate and the second basin skirt plate; the centering positioning member 6 is composed of a positioning pipe; the first basin structure and the second basin structure are integrally formed by casting, the first jacking pre-tightening support plate and the inner reinforcing rib plate arranged in the first basin structure are fixed on the first basin structure by welding, and the second jacking pre-tightening support plate and the inner reinforcing rib plate arranged in the second basin structure are fixed on the second basin structure by welding.
[0058] Compared with example five, in the technical solution described in this example, the groove structure constituting the jacking space B is symmetrically arranged on both sides of the first basin structure and the second basin structure, which can save space in the width direction of the vibration isolation device, and the rectangular outline of the upper shell and the lower shell can better adapt to the installation scene limited in the width direction.
[0059] Similarly, the elastic element 1 can also be arranged only in part of the grid formed by the inner reinforcing rib plate and the first basin skirt plate (equivalent to the grid formed by part of the inner reinforcing rib plate and the second basin skirt plate), for example, the elastic element is arranged only in the grid formed by the four inner reinforcing rib plates and the first basin skirt plate near the jacking space B, and the two grids in the middle can be used as a reserve installation interface of the elastic element when the bearing capacity is insufficient. In addition, in this example, the first basin structure and the second basin structure are both rectangular outlines, and the elastic element is arranged in two rows and three columns, but in practice, the first basin structure and the second basin structure can also be square outlines, and the elastic element can be arranged in three rows and three columns, at this time, the elastic element can be arranged not only in the grid formed by the inner reinforcing rib plate and the first basin skirt plate (equivalent to the grid formed by the inner reinforcing rib plate and the second basin skirt plate), but also in the grid formed between the inner reinforcing rib plates; of course, the elastic element can also be arranged only in part of the grid.
[0060] Based on the technical principle of the example, the contour shape surrounded by the first basin skirt plate in the cross section of the first basin structure and the second basin skirt plate in the cross section of the second basin structure can also be a square or other polygon with an even number of sides and symmetrical arrangement along the median plane, which can also achieve good technical effects. It is particularly pointed out that the super-thin vibration isolation device with jacking space formed by the relatively regular-shaped basin structure of the utility model is easy to realize the force balance of all elastic elements during jacking installation and use, has better stability, is the preferred selection scheme for engineering application, and is within the protection scope required by the utility model.
[0061] Example Seven
[0062] As shown in Figure 12 and Figure 13 , the super-thin vibration isolation device with jacking space of the utility model is different from the technical scheme shown in Figure 11 in that the contour shape surrounded by the first basin skirt plate 4 in the cross section of the first basin structure of the upper shell is a square, and correspondingly, the contour shape surrounded by the second basin skirt plate 11 in the cross section of the second basin structure of the lower shell is also a square. In addition, in the first basin structure of the upper shell, the inner reinforcing rib plate 14 is arranged radially from the middle of the first basin bottom plate 3 to the four corner parts of the square first basin skirt plate 4, and correspondingly, in the second basin structure of the lower shell, the inner reinforcing rib plate 14 is arranged radially from the middle of the second basin bottom plate 10 to the four corner parts of the square second basin skirt plate 11. In addition, the pre-tightening connecting structure further includes a counter-pressure elastic element 18, the direction of the force of the counter-pressure elastic element 18 on the upper shell or the lower shell is opposite to the direction of the supporting force of the elastic element 1 on the upper shell or the lower shell, and in this example, the counter-pressure elastic element 18 is specifically a disc spring. In the upper shell, the groove structure forming the jacking space B is symmetrically arranged around the first basin structure, and correspondingly, in the lower shell, the groove structure forming the jacking space B is symmetrically arranged around the second basin structure.
[0063] Compared with example six, in the technical solution of the example, the contour shape surrounded by the first basin skirt plate in the cross section of the first basin structure of the upper shell is a square, the contour shape surrounded by the second basin skirt plate in the cross section of the second basin structure of the shell is also a square, and in the upper shell, the groove structures constituting the jacking space B are symmetrically arranged around the first basin structure, and correspondingly, in the lower shell, the groove structures constituting the jacking space B are symmetrically arranged around the second basin structure, so that the ultrathin vibration isolation device with a jacking space of the utility model has no difference in length and width when placed and applied; in addition, the counter-pressure elastic element 18 is additionally arranged in the pre-tightening connection structure, at this time, the pre-tightening connection structure constitutes a tensile connection structure between the upper shell and the lower shell, when subjected to strong upward impact caused by, for example, an earthquake, the relative movement between the upper shell and the lower shell can be elastically buffered, on the one hand, the pre-tightening connecting piece 7 can be prevented from being pulled off, and on the other hand, the upward pulling force generated when the elastic element rebounds can be offset by using the counter-pressure force provided by the counter-pressure elastic element, so as to avoid the situation that the elastic element jumps too much, the elastic element is pulled out of the center limiting piece and falls, and the stability and safety of the product during work are improved.
[0064] Example eight
[0065] As Figure 14 and Figure 15 indicated, the ultrathin vibration isolation device with a jacking space of the utility model is different from example seven in that the contour shape surrounded by the first basin skirt plate 4 in the cross section of the first basin structure of the upper shell is a hexagon, and correspondingly, the contour shape surrounded by the second basin skirt plate 11 in the cross section of the second basin structure of the lower shell is also a hexagon; the inner reinforcing rib plate 14 is arranged in the first basin structure of the upper shell and the second basin structure of the lower shell, respectively, and the inner reinforcing rib plate 14 is arranged in a honeycomb shape; the elastic element 1 is arranged in the grid surrounded by the inner reinforcing rib plate 14, and the elastic element 1 is specifically a rubber spring.
[0066] Compared with example seven, in the technical solution described in this example, the upper shell and the lower shell have stronger bending resistance due to the adoption of the honeycomb-shaped arrangement of the inner reinforcing rib plates. In addition, the elastic element in this example adopts a rubber spring. Since the rubber spring can provide good elasticity and damping at the same time, the rubber spring can be used as an elastic element and a damping element at the same time. It should be pointed out that, in order to leave space for the elastic deformation of the rubber spring, a through hole is arranged in the middle of the rubber spring, and a proper gap is also reserved between the rubber spring and the inner reinforcing rib plate. However, for some special elastic elements, such as a polyurethane microcellular foam elastic block, since a large number of microcellular holes in the polyurethane microcellular foam elastic block can provide sufficient deformation space, a through hole does not need to be arranged in the middle of the polyurethane microcellular foam elastic block, and the polyurethane microcellular foam elastic block can fill the lattice surrounded by the inner reinforcing rib plate 14. The polyurethane microcellular foam elastic block is centered and positioned by the inner reinforcing rib plate, and a special centering and positioning member is not needed, which is conducive to further simplifying the product structure. Of course, based on the technical principle of this example, the contour shape surrounded by the basin skirt plate in the basin-shaped structure constituting the upper shell and the lower shell can also be an octagon or other polygon with an even number of sides. These are simple changes based on the technical principle of the utility model, which are only described in words here and are also within the protection scope required by the utility model.
[0067] Based on the foregoing technical principle of this example, in order to save materials, such as Figure 16 The ultra-thin vibration isolation device with a jacking space of the utility model shown in the foregoing description has a first basin-shaped structure. The outer periphery of the honeycomb-shaped lattice is formed by the first basin skirt plate 4. The upper part of the corresponding elastic element 1 is arranged in the lattice surrounded by the first basin skirt plate 4 and the inner reinforcing rib plate 14 or is arranged in the lattice surrounded by the inner reinforcing rib plate 14. The second basin-shaped structure is similar to the first basin-shaped structure, and will not be described again. Compared with the technical solution shown in Figure 15 Compared with the technical solution shown in
[0068] Of course, based on the technical principle of the utility model of the Figure 8 In addition to the honeycomb-shaped arrangement, the inner reinforcing rib plate can also be arranged in other forms, such as Figure 17As shown in the middle, the inner reinforcing rib plate arranged in the basin structure of the upper shell and the lower shell can also be jointly constituted by the concentric reinforcing rib 15 and the centripetal reinforcing rib 16, specifically, in the first basin structure of the upper shell, the contour shape of the concentric reinforcing rib 15 is hexagonal like the contour shape of the first basin skirt plate 4, and the two ends of the centripetal reinforcing rib 16 are connected with the first basin skirt plate 4 and the concentric reinforcing rib 15 respectively, and correspondingly, in the second basin structure of the lower shell, the contour shape of the concentric reinforcing rib 15 is hexagonal like the contour shape of the second basin skirt plate 11, and the two ends of the centripetal reinforcing rib 16 are connected with the second basin skirt plate 11 and the concentric reinforcing rib 15 respectively, and a very good technical effect can also be achieved, which is also within the protection scope of the utility model.

Of course, based on the technical principle of the present example, the laminated rubber support 19 can also be connected in series with the upper shell, and similar technical effects can also be achieved. In addition, in addition to the laminated rubber support mentioned above, other types of anti-seismic devices such as slide plate pairs or friction pendulum supports can also be connected in series with the upper shell or the lower shell, and good vibration and earthquake double control technical effects can also be achieved.
