[0031] Embodiment one
[0032] Referring to Figure 1 、 Figure 2 The shock isolation device provided by the embodiment comprises a support assembly 100 and a reset member 200.
[0033] The support assembly 100 comprises a first platform 110 and a second platform 120, the first platform 110 and the second platform 120 are spaced apart along the vertical direction, the first platform 110 is located above the second platform 120 and forms a setting space between the first platform 110 and the second platform 120, and the top surface of the first platform 110 is a concave structure. The reset member 200 is a spherical structure, and the reset member 200 is arranged in the setting space and can roll in the setting space.
[0034] And, in the embodiment, each support assembly 100 and the reset member 200 form a reset unit, and there are at least three reset units, and the reset units are arranged in a ring at the same horizontal plane, and the first platforms 110 of the reset units are connected end to end to form a bearing table for bearing the equipment.
[0035] Specifically, in the embodiment, the reset member 200 is connected to the bottom surface of the first platform 110 and can rotate. In this structure, when vibration occurs or the equipment is impacted, the reset members 200 in the reset units all roll and rub along the concave plane to consume vibration energy, and the first platform 110 moves with the reset member 200 during rolling of the reset member 200.
[0036] After the vibration ends, the first platform 110 and the reset member 200 in the reset unit automatically return to the initial position by their own weight and the gravity of the equipment they bear and the concave structure of the top surface of the second platform 120, achieving the automatic reset function. The shock isolation device provided in the embodiment does not need to rely on elasticity during the shock absorption process and the reset process, thereby preventing mechanical fatigue and material aging caused by vibration, effectively preventing large vibration and lateral displacement of the equipment, and effectively reducing the impact of the earthquake on the equipment, thereby prolonging the service life of the equipment.
[0037] In addition, since the reset member 200 with a spherical structure needs to bear the entire weight of the first platform 110 and the equipment on the first platform 110, in the embodiment, the reset member 200 with a spherical structure is made of high-strength steel.
[0038] As an implementable way, the reset member 200 can also be connected to the top surface of the second platform 120 and can rotate, and in this structure, the bottom surface of the first platform 110 needs to be provided with a concave structure. When vibration occurs or impact is received, the first platform 110 moves under the rolling of the concave structure and the reset member 200, and returns to the initial position by its own weight and the concave structure after the vibration and impact end, and the same can achieve the shock absorption effect.
[0039] Embodiment Two
[0040] Reference Figure 2 In the embodiment, the bottom surface of the first platform 110 and the top surface of the second platform 120 are both concave structures. The lowest point of the bottom surface of the first platform 110 is opposite to the lowest point of the top surface of the second platform 120.
[0041] Specifically, when vibration occurs or the device is impacted, the first platform 110 in the plurality of reset units in the embodiment can remain relatively stationary, the second platform 120 and the first platform 110 generate relative motion through the flat surface of the reset member 200 and the inner recess structure, and the reset member 200 rolls and rubs along the two inner recess flat surfaces in the setting space to consume vibration energy. Under this structure, compared with the first embodiment, the relative displacement stroke between the second platform 120 and the first platform 110 in the embodiment is longer, and the shock absorption effect is more excellent.
[0042] It should be noted that before the reset member 200 moves, the reset unit and the device carried thereby have the same natural vibration period, and after being subjected to vibration, the first platform 110 and the second platform 120 slide relatively, and the entire system has a large shock isolation period (about 3 seconds), which is usually more than three times the ordinary structure period, thereby significantly reducing the acceleration and seismic force experienced.
[0043] In the embodiment, the bottom surface of the first platform 110 and the top surface of the second platform 120 are both arc surface structures.
[0044] Since the bottom surface of the first platform 110 and the top surface of the second platform 120 are both arc surface structures, the rolling path of the spherical reset member 200 in the setting space is further lengthened. When the device is subjected to vibration or impact, the reset member 200 can roll in a larger range, thereby increasing the relative displacement stroke and further improving the shock absorption capacity.
[0045] In addition, the arc surface structure can be suitable for composite vibration from different directions. Regardless of the change in the direction of vibration, the reset member 200 can smoothly roll on the arc surface to achieve omnidirectional energy dissipation.
[0046] As an implementable manner, the bottom surface of the first platform 110 and the top surface of the second platform 120 can also be formed into inclined surfaces to form inner recess structures, and the spherical reset member 200 can also roll in the inner recess structures formed by the inclined surface structures, thereby achieving the technical effects of shock isolation and shock absorption.
[0047] It should be noted that when the bottom surface of the first platform 110 and the top surface of the second platform 120 are formed into inclined surface structures, through repeated design and testing, the shock absorption effect and reset effect of the shock isolation device are optimal when the angle between the inclined surface and the horizontal plane is 6-8 degrees.
[0048] In the embodiment, the bottom surface of the first platform 110 and the top surface of the second platform 120 are both arc surface structures.
[0049] In the embodiment, the limiting portion 130 is arranged at the edge of the bottom surface of the first platform 110 and the top surface of the second platform 120, and the limiting portion 130 encloses the bottom surface of the first platform 110 and the top surface of the second platform 120 from the outside. The limiting portion 130 protrudes outwardly from the first platform 110 and the second platform 120, which can avoid the reset member 200 from being pulled out of the setting space due to excessive stroke when the first platform 110 and the second platform 120 move relatively, and thus the first platform 110 is prevented from falling.
[0050] In the embodiment, the shock isolation device further comprises a plurality of connecting members 300. The plurality of first platforms 110 are connected by the connecting members 300.
[0051] The connecting members 300 are used to connect the reset units, so that the plurality of first platforms 110 can form a larger plane for the bearing device and can ensure that the plurality of first platforms 110 move synchronously.
[0052] In the embodiment, the plurality of second platforms 120 are arranged correspondingly to the plurality of first platforms 110 and are connected by the plurality of connecting members 300, so that the plurality of second platforms 120 can form a stable whole for bearing, thereby ensuring the stability of bearing.
[0053] Referring to Figure 3 In the embodiment, the side surface of the first platform 110 is provided with a plurality of connecting holes 140. The plurality of connecting holes 140 are arranged at intervals along the circumference of the first platform 110. The two ends of the connecting member 300 can be detachably connected with the connecting holes 140.
[0054] Specifically, the connecting holes 140 in the embodiment are arranged on the limiting portion 130, and the two ends of the connecting member 300 are provided with screw holes, and the two ends of the connecting member 300 are detachably connected with the first platform by screws.
[0055] In the embodiment, the support assembly 100, the reset member 200 and the connecting member 300 are made of stainless steel.
[0056] The surface of stainless steel is smooth and the friction coefficient is relatively stable, which helps the reset member 200 to maintain uniform friction during rolling, further improves the energy dissipation efficiency and shock absorption effect, and has wear resistance, so that the reset member 200 is not easy to wear during rolling and friction in the setting space. The maintenance frequency is reduced, and the overall service life of the shock isolation device is prolonged.
[0057] In addition, the bearing capacity of stainless steel material is higher and the size is smaller than other products made of rubber or spring, and the overall height can be less than 10 cm, without occupying too much space, saving space while reducing the cost.
[0058] In addition, in a special environment of high salt and high humidity, the durability of the stainless steel material is better, and it is not easy to be damaged by corrosion.
[0059] In the embodiment, the surfaces of the support assembly 100, the reset member 200 and the connecting member 300 are provided with elastic buffer layers.
[0060] The elastic buffer layer can further improve the shock absorption capacity of the shock isolation device, and in the embodiment, the elastic buffer layer is made of plastic material, which is very stable in chemical properties, and can further improve the applicability of the shock isolation device.
[0061] In the embodiment, the reset unit has four. The four reset units are arranged in a rectangular structure.
[0062] Again refer to Figure 1 In the embodiment, the four reset units are arranged in a square structure, and the four reset units are located at the four corners of the square, respectively. The four reset units are connected into an integral structure by the connecting member 300, and a bearing plate or a bearing seat can be further arranged on the integral structure, and then the equipment is placed in the center of the square integral structure, and the support is very stable.
[0063] It should be noted that, as an implementable manner, when a larger equipment is used, the four reset units can be connected in the above manner to form a subunit, and a plurality of subunits can be connected according to the shape of the equipment, so as to further increase the bearing area, so as to realize the bearing of the large equipment.
[0064] In the embodiment, the cross section of the first platform 110 is a rectangular surface. The curved surface structure is a spherical surface, and the center of the spherical surface and the center of the rectangular surface are located on the same straight line.
[0065] The rectangular surface as the cross section of the first platform 110 provides a larger support area, enhances the stability of the reset unit. Even in the case of larger vibration or impact, the rectangular surface can effectively disperse the load, maintain the integrity of the structure, and the alignment state of the center of the spherical surface and the rectangular surface can prevent the first platform 110 from overturning in an extreme case, and increase the safety and reliability of the shock isolation device.
[0066] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features. The modification or replacement does not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the present application.
