Description

Technical Field

[0001] This utility model belongs to the field of grain warehouse structure technology, and more specifically, it relates to a vibration reduction and isolation grain warehouse structure. Background Technology

[0002] Large-scale grain storage is a preparation for national disasters caused by force majeure. Safe and green grain storage is part of the national strategic plan. my country has a large population and is a major grain-storing country. Grain storage requires the construction of grain silos. In the construction of grain silos, the quality of the silo structure's vibration damping and isolation functions directly affects the service life of the silos. Many factors can cause grain silo vibration, but based on experience, the most important factors can be summarized as follows: 1. Earthquakes or geological disasters (landslides, collapses, rockfalls, etc.) causing vertical and horizontal vibrations of the grain silos; 2. Storms or floods causing swaying of the grain silos; 3. Vibrations caused by shock waves from explosives or impacts from foreign objects (such as cars); 4. The weight of grain falling in large quantities from a height when it is being stored can also cause grain silo vibration.

[0003] Vibration has a strong destructive force on grain silos, which greatly affects their service life. In severe cases, it may cause the grain silos to collapse and cause irreparable losses and consequences. After research, the following defects or deficiencies were found in the application of existing vibration reduction and isolation technologies for grain silos: 1. Vibration isolation supports buffer vibrations and have a self-resetting function, which relies on rubber and springs to achieve this purpose. However, existing vibration isolation supports are prone to aging and deformation due to the pressure of the silo and exposure to sun and rain over the years, and replacement is difficult. Therefore, their vibration reduction and isolation effect will gradually deteriorate with the increase of years; 2. During the shaking of the silo, due to its high center of gravity, the vibration isolation support may be squeezed on one side due to the shift of the silo's center of gravity, which further increases the overall deflection angle of the silo and may even break the bolts fixed to the vibration isolation support; 3. During the lateral swaying of the silo, the top of the support column is prone to a large deflection angle. Therefore, when using a lateral self-resetting energy dissipation device, if the connection is not movable, the angle of the connection device cannot be adaptively adjusted, which may cause the self-resetting device to be damaged by stress; from another perspective, if the connection is not movable, it cannot adapt to different grain silos. Designing and manufacturing a self-resetting device separately will increase production costs and is not convenient for quick and efficient installation.

[0004] The inventors of this application, relying on the university's grain warehouse research platform and national project funding, have improved upon the above-mentioned shortcomings and proposed a new vibration-damping grain warehouse structure. Utility Model Content

[0005] Based on the above background technical analysis, this utility model provides a vibration reduction and isolation grain silo structure to solve the problems in the prior art, such as the aging and difficulty in replacing the vibration isolation support of the grain silo leading to failure, the possibility of bolt breakage due to lateral vibration waves, and the inability of the self-resetting device to adapt to the stress angle.

[0006] This utility model provides a vibration-damping grain silo structure, which is achieved through the following specific technical solutions:

[0007] A vibration-damping grain silo structure includes a silo cylinder, a ring beam, and at least one support column. The silo cylinder is connected and fixed to the ring beam via an upper vibration-damping support, and the support column is connected and fixed to the ring beam via a lower vibration-damping support. The structure also includes a vibration-damping device composed of the upper and lower vibration-damping supports. The vibration-damping device is installed on the ring beam between adjacent support columns.

[0008] The vibration isolation lower support is symmetrically provided with self-resetting side seats on both sides; the self-resetting side seats of adjacent vibration isolation lower supports are fixedly connected by steel cables; the vibration reduction and isolation device also has a connecting rod, and the ring beam corresponding to the vibration reduction and isolation device is provided with holes through which the connecting rod can pass through from top to bottom. The upper end of the connecting rod is connected to the top of the vibration isolation upper support, and its lower end abuts against the bottom of the vibration isolation lower support.

[0009] Furthermore, both the upper and lower vibration isolation supports are composed of steel plates, rubber, support springs, upper connecting plates, and lower connecting plates. The steel plates and rubber are alternately stacked between the upper and lower connecting plates. The support springs are located around the steel plates and rubber, with their upper ends connected to the upper connecting plates and their lower ends connected to the lower connecting plates. The upper and lower connecting plates of the upper vibration isolation support are respectively fixedly connected to the silo and the ring beam by bolts. The upper connecting plates of the lower vibration isolation support are all fixedly connected to the ring beam by bolts, and the lower connecting plate of the lower vibration isolation support at the support column is fixedly connected to the support column by bolts.

[0010] Furthermore, both the lower connecting plate of the upper vibration isolation support and the upper connecting plate of the lower vibration isolation support are provided with openings. The connecting rod passes through the openings, the ring beam holes, and all the steel plates and rubber. Its upper end is fixed to the lower surface of the upper connecting plate, and its lower end abuts against the upper surface of the lower connecting plate.

[0011] Furthermore, the upper connecting plate of the vibration isolation upper support has a limiting strip on its upper surface, and the bottom of the silo is provided with a matching groove.

[0012] Furthermore, the self-resetting side seat includes a top plate, a side plate, a bottom plate, a movable plate, a connecting cylinder, a side seat spring, and two force-bearing plates. One end of the top plate and the bottom plate are fixedly connected through the side plate, and the other end is fixedly connected through the force-bearing plates. One end of the side seat spring is fixed to the movable plate, and the other end is fixed to the side plate. The connecting cylinder is connected to the movable plate, and the top plate is fixedly connected to the ring beam by bolts.

[0013] Furthermore, the connecting cylinder includes connecting cylinder one and connecting cylinder two, both of which have a "V" shaped structure. Connecting cylinder one of adjacent self-resetting side seats is fixedly connected by steel cables. The bottom plate has a "U" shaped hole in the middle. Connecting cylinder two at the vibration reduction and isolation device is connected to the support seat sleeved on the outer surface of the nearest support column by steel cables.

[0014] Furthermore, the support base is fixed to the support column by bolts, and each of its two outer surfaces has a connecting cylinder three. The connecting cylinder two is fixedly connected to the nearest connecting cylinder three by steel cable.

[0015] Furthermore, the upper surface of the base plate and both sides of the top plate are respectively provided with sliding grooves, and the four corners of the movable plate are fitted with sliding structures matching the sliding grooves.

[0016] Furthermore, the movable plate has a movable hole in the middle, and the self-resetting side seat also includes a limiting ball. The connecting cylinder passes through the movable hole and is fixed to the limiting ball, and the diameter of the limiting ball is larger than that of the movable hole.

[0017] Furthermore, it also includes a transition bracket, one end of which is fixed to the ring beam between the vibration damping and isolation device and the support column by bolts, and the other end has a bracket hole through which the steel cable can pass.

[0018] This utility model has at least the following beneficial effects:

[0019] 1. This utility model uses an upper vibration isolation support and a lower vibration isolation support to fix the silo, ring beam and support column to each other, so that the grain silo of this application has the ability to resist longitudinal vibration waves; in addition, self-resetting side seats are provided on both sides of the lower vibration isolation support, and different self-resetting side seats are connected in sequence by steel cables, so that it has the ability to resist transverse vibration waves.

[0020] 2. This utility model includes a vibration damping and isolation device, which consists of an upper vibration isolation support, a lower vibration isolation support, and a connecting rod. The upper end of the connecting rod is fixed to the upper connecting plate of the upper vibration isolation support, and the lower end abuts against the lower connecting plate of the lower vibration isolation support. When longitudinal vibration occurs, the vibration can be transmitted to the lower vibration isolation support through the connecting rod, thereby enhancing the vibration damping effect of the vibration damping and isolation device. Furthermore, after years of exposure to sun and rain, the vibration damping and isolation effect of the device will deteriorate. However, the lower vibration isolation support in this application is relatively easy to replace, thus extending the service life of the vibration damping and isolation device.

[0021] 3. The connecting rod of this utility model passes through the hole in the ring beam, and the upper surface of the vibration isolation support has a limiting strip, so that the grain silo can better maintain stability when subjected to lateral impact force or vibration wave, reduce the center of gravity shift, avoid excessive shaking and center of gravity shift that would cause the bolts of the vibration isolation support to break, and effectively prevent the silo from tipping over.

[0022] 4. The self-resetting side seat of this utility model includes a connecting cylinder, and the connecting cylinder one and the connecting cylinder two form a "V" shaped structure. The connecting cylinder one in adjacent reset side seats is connected to each other by steel cables and has a self-resetting function in the lateral direction. The connecting cylinder two is connected to the connecting cylinder three of the support seat on the support column by steel cables, thereby forming a triangular structure, which increases the stability of the support column and the ring beam.

[0023] 5. The connecting cylinder of this utility model passes through the movable hole of the movable plate and is fixedly connected to the limiting ball. The diameter of the limiting ball is larger than that of the movable hole, so that the connecting cylinder can adaptively adjust the angle to prevent the steel cable from being damaged by stress due to the inconsistency between the direction of the steel cable and the orientation of the connecting cylinder when vibration occurs. In addition, the movable adjustment of the connecting cylinder also facilitates the quick and efficient adjustment and installation of the steel cable during installation.

[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0033] Example 1:

[0034] See appendix Figure 1-6This utility model provides a vibration-damping and isolation grain silo structure, including a silo cylinder 1, a ring beam 2, and at least three support columns 3. The silo cylinder 1 is connected and fixed to the ring beam 2 through an upper vibration isolation support 41, and the support columns 3 are connected and fixed to the ring beam 2 through a lower vibration isolation support 42. It also includes a vibration-damping and isolation device 4 composed of the upper vibration isolation support 41 and the lower vibration isolation support 42. The vibration-damping and isolation device 4 is installed on the ring beam 2 between adjacent support columns 3. The optimal solution is to install it in the exact middle of this section of the ring beam 2 to ensure overall aesthetics and stress balance.

[0035] The vibration isolation lower support 42 is symmetrically provided with self-resetting side seats 5 on both sides; the self-resetting side seats 5 opposite each other of the adjacent vibration isolation lower support 42 are fixedly connected by steel cables; the vibration reduction and isolation device 4 also has a connecting rod 43, and the ring beam 2 corresponding to the vibration reduction and isolation device 4 is provided with a hole through which the connecting rod 43 can pass through from top to bottom. The upper end of the connecting rod 43 is connected to the top of the vibration isolation upper support 41, and its lower end abuts against the bottom of the vibration isolation lower support 42.

[0036] In practice, the vibration isolation upper support 41 other than the vibration isolation device 4 can be installed directly above the ring beam 2 at the support column 3. In addition, depending on the diameter of the silo, an appropriate number of vibration isolation upper supports 41 can be added to the ring beam 2 between the two vibration isolation upper supports 41.

[0037] The above technical solutions suffer from the "top-heavy" phenomenon when the grain silo is full of grain, making the support column 3 prone to tipping over or breaking due to vibration. By adding the upper vibration isolation support 41, the lower vibration isolation support 42, and the vibration reduction and isolation device 4, the overall ability to resist longitudinal vibration waves is enhanced. At the same time, self-resetting side seats 5 are set on both sides of each lower vibration isolation support 42, and the self-resetting side seats 5 of adjacent lower vibration isolation supports 42 are connected by steel cables, which can better resist lateral vibration waves.

[0038] Example 2:

[0039] Based on Example 1, see [link / reference] Figure 3 , 4 Both the upper vibration isolation support 41 and the lower vibration isolation support 42 are composed of steel plate 411, rubber 412, support spring 413, upper connecting plate 414, and lower connecting plate 415. The steel plate 411 and rubber 412 are alternately stacked between the upper connecting plate 414 and the lower connecting plate 415. The support spring 413 is located around the steel plate 411 and rubber 412, with its upper end connected to the upper connecting plate 414 and its lower end connected to the lower connecting plate 415. The upper connecting plate 414 and the lower connecting plate 415 of the upper vibration isolation support 41 are respectively fixedly connected to the silo 1 and the ring beam 2 by bolts. The upper connecting plate 414 of the lower vibration isolation support 42 is fixedly connected to the ring beam 2 by bolts, and the lower connecting plate 415 of the lower vibration isolation support 42 at the support column 3 is fixedly connected to the support column 3 by bolts.

[0040] In a better technical solution, the lower connecting plate 415 of the upper vibration isolation support 41 and the upper connecting plate 414 of the lower vibration isolation support 42 are both provided with openings. The connecting rod 43 passes through the openings, the two holes of the ring beam, and all the steel plates 411 and rubber 412. Its upper end is fixed to the lower surface of the upper connecting plate 414, and its lower end abuts against the upper surface of the lower connecting plate 415 (when the upper vibration isolation support is compacted and stationary).

[0041] A better technical solution is that the upper connecting plate 414 of the vibration isolation upper support 41 has a limiting strip 411 on its upper surface, and the bottom of the silo 1 is provided with a matching groove.

[0042] The above technical solutions allow for better self-reset when the grain silo vibrates vertically. The vibration energy can be offset by the upper vibration isolation support 41 and the lower vibration isolation support 42, which abuts against the connecting rod 43. Furthermore, since the lower vibration isolation support 42 at the vibration isolation device 4 is located on the ring beam 2 and is not fixed to the connecting rod 43, it can be easily replaced after years of exposure to sun and rain, ensuring the overall vibration isolation and damping effect remains at a certain level. Finally, when the grain silo sways left and right, a large skew angle may occur. The support from the connecting rod 43 and the limiting strip 411 effectively prevents the upper vibration isolation support 41 from deforming or the bolts from breaking, thereby improving its resistance to lateral vibration waves.

[0043] Example 3:

[0044] Based on Example 1, and referring to Figure 1-6 The self-resetting side seat 5 includes a top plate 51, a side plate 52, a bottom plate 53, a movable plate 54, a connecting cylinder 55, a side seat spring 56, and two force-bearing plates 57. One end of the top plate 51 and the bottom plate 53 are fixedly connected to the side plate 52, and the other end is fixedly connected to the force-bearing plate 57. One end of the side seat spring 56 is fixed to the movable plate 54, and the other end is fixed to the side plate 52. The connecting cylinder 55 is connected to the movable plate, and the top plate 51 is fixedly connected to the ring beam 2 by bolts. In specific implementation, the top plate 51 and the lower connecting plate 415 of the vibration isolation lower support 42 can be welded together, or they can be integrally formed.

[0045] A better technical solution is that the connecting cylinder 55 includes a first connecting cylinder 551 and a second connecting cylinder 552, both of which have a "V" shaped structure. The first connecting cylinder 551 of adjacent self-resetting side seats 5 is fixedly connected by steel cables. The bottom plate 53 has a "U" shaped hole in the middle. The second connecting cylinder 552 at the vibration damping and isolation device 4 is connected to the support seat 6 sleeved on the outer surface of the nearest support column 3 by steel cables. The "U" shaped hole can ensure that the steel cable connection between the second connecting cylinder 552 and the support seat 6 is not affected.

[0046] Furthermore, the support base 6 is fixed to the support column 3 by bolts, and each of its two outer surfaces has a connecting cylinder 3 61. The connecting cylinder 2 552 is fixedly connected to the nearest connecting cylinder 3 61 by steel cable.

[0047] In the above technical solution, since the angle of the "V" shaped structure is fixed, the position of the support seat 6 on the support column 3 can be adjusted to adapt to the angle, thus not affecting the connection of the steel cable. This technical solution allows the support column 3 and one section of the ring beam 2 to maintain a triangular structure, thereby improving the stability of the support column 3.

[0048] A superior technical solution involves providing corresponding grooves 7 on the upper surface of the base plate 53 and both sides of the top plate 51. Sliding structures 8 are installed at the four corners of the movable plate 54, matching the grooves 7. This solution reduces friction between the movable plate 54 and the top plate 51 and base plate 53, allowing for better movement after vibration, and also limits the movable plate 54, improving its stability. The sliding structure 8 can be a roller, ball bearing, slider, or other structure that reduces friction.

[0049] A better technical solution is provided, in which the movable plate 54 has a movable hole in the middle, and the self-resetting side seat 5 also includes a limiting ball 58. The connecting cylinder 55 passes through the movable hole and is fixed to the limiting ball 58, and the diameter of the limiting ball 58 is larger than that of the movable hole, while the diameter of the movable hole is smaller than the maximum distance of the "V" shaped structure. The connecting cylinder 61 on the support seat 6 can also be made movable according to the actual situation to adapt to different installation angles and steel cable stress angles.

[0050] A better technical solution also includes a transition bracket 9, one end of which is fixed to the ring beam 2 between the vibration damping and isolation device 4 and the support column 3 by bolts, and the other end has a bracket hole 91 through which a steel cable can pass. Multiple transition brackets 9 can be set depending on the specific situation.

[0051] In the above technical solution, the connecting cylinder 55 can be adjusted in angle. On the one hand, this can adapt to the stress direction of the steel cable during vibration, reducing the probability of damage to the connecting cylinder 55. On the other hand, it can ensure that the steel cable conforms to the orientation of the connecting cylinder 55 during installation, thus ensuring proper installation. Similarly, the installation of the transition bracket 9 also ensures that the direction of the steel cable better adapts to the orientation of the connecting cylinder 55, preventing the connecting cylinder 55 from being damaged by the stress of the steel cable.

The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
