Description

[0001] BI-DIRECTIONAL ISOLATION DEVICE FOR PRODUCTS STORED ON TRAYS IN RESPONSE TO EXTERNAL MOVEMENTS

[0002] DESCRIPTIVE MEMORANDUM

[0003] FIELD OF INVENTION

[0004] The present utility model relates to the industry of insulation devices related to supporting seismic loads and / or loads produced by movement during transport, particularly in the construction industry of non-structural insulating elements such as shelves, racks, cabinets, among others, both for fixed structures and for means of transport.

[0005] An apparatus for isolating masses stored on industrial storage shelves in response to external movements or vibrations, comprising a platform that houses industrial products and rests directly on the shelving beams. This platform internally has horizontal and vertical springs in a set of plates linked together by a bidirectional helix system, such that the lateral movement of the platform with respect to the storage structure is controlled by a maximum permissible displacement of the spring assembly. The springs have different coefficients of elasticity or stiffness, with a displacement limit for the spring with the lowest stiffness coefficient. This allows objects of high and / or low weight to be isolated on the same tray, and thanks to the helix configuration, the object can be placed anywhere on the tray.Therefore, it doesn't necessarily have to go in the center of the tray. Furthermore, this pallet isolation platform is arranged at different levels of the storage structure by attaching the platform supported by the beams.

[0006] STATE OF THE ART

[0007] Currently, the industry of load-bearing devices designed to withstand movement presents the drawback that they are only focused on decoupling a surface from a base. A single device cannot support loads of varying weights, nor can it accommodate loads placed anywhere on the base, as they are generally designed to support central loads. Several solutions have been found in the state of the art that partially resolve this technical problem. Among the known solutions is publication CN110513434A, which discloses a seismic isolation unit with orthogonal guide tracks. This unit includes a top plate, a bottom plate, two impact isolation plates mounted upwards and downwards, and an assembly of impact isolation components. The impact isolation component includes two groups of linear guide components and a group of sliding seats.Two groups of reset connectors; the orthogonal configuration of two groups of linear guide components is mounted separately on two impact isolation plates; a sliding seat connects to two groups of linear guide components one above the other simultaneously, and a sliding seat connects to the floating end of two groups of reset connectors simultaneously, and two groups of reset connectors are mounted separately on two impact isolation plate components away from the fixing end of the sliding assemblies; under normal operating conditions, the center of gravity limiting the impact isolation component of each impact isolation plate is always located in the region where two impact isolation plates overlap. The invention improves the entire anchoring of the seismic isolation equipment; the newly constructed seismic isolation equipment can be used alone.However, this equipment does not allow for bidirectional isolation of products or objects stored on trays in response to seismic movements or external forces, regardless of the weight of the load, which can be light (less than or equal to 300 kg) or heavy (greater than 300 kg), and regardless of the location of said load on the trays, since this document only supports loads in the center.

[0008] Another document is patent US6385917 BA, which discloses a base isolation device used to absorb ground shaking, such as an earthquake, to reduce the shaking of a building, or to reduce shaking applied to precision machinery and tools during transport, etc. The base isolation device comprises first and second track rails arranged orthogonally to each other, a first sliding element linearly movable along the first track rail, a second sliding element connected to the first sliding element and linearly movable along the second track rail, a ball screw for converting linear motion of the second sliding element into rotary motion, and a rotating sleeve imparted to rotation by the ball screw.A stationary sleeve forms a damping force action chamber between itself and an outer peripheral face of the rotating sleeve, and a viscous fluid is sealed in the action chamber. However, this device does not allow for bidirectional isolation of products or objects stored on trays in response to seismic movements or external forces, regardless of the weight of the load, which can be light (less than or equal to 300 kg) or heavy (greater than 300 kg), and regardless of the location of said load on the trays, since this document only supports loads in the center.

[0009] On the other hand, among the documents with a motion isolation system is patent application PCT / IB2018 / 059935, which discloses a kinematic seismic isolation device for isolating a superstructure from the movement experienced by a substructure or foundation, providing lateral stability and tensile strength. This device comprises a rigid shell with the convex part of the shell facing upwards and a radius of curvature R, which may be constant or variable; and an intermediate rigid body that is coupled at its upper end to the lower part of the shell and extends to a lower end of the device where it connects via a pivoting connection means to the substructure or foundation.where the radius of curvature R is greater than or equal to the height H of the device, but these isolation devices do not allow orthogonal movement to decouple the movements produced by different lateral loads nor are they independent of the location of said load on the trays.

[0010] SOLUTION TO THE TECHNICAL PROBLEM

[0011] To address the problem, a device is presented for the bidirectional isolation of products stored on trays in response to seismic movements or external forces, independent of the load weight, which can be light (less than or equal to 300 kg) or heavy (greater than 300 kg), and independent of the load's location on the trays, achieving orthogonal decoupling. SUMMARY DESCRIPTION OF THE INVENTION.

[0012] The present utility model is an apparatus for the bidirectional isolation of products stored on trays in response to seismic movements or external forces, independent of the weight of the load, which can be light (less than or equal to 300 kg) or heavy (greater than 300 kg), and independent of the location of said load on the trays, comprising: a chassis or frame comprising at least two parallel vertical structures connected by at least one pair of horizontal structural beams, where each pair of horizontal structural beams forms a storage shelf level; where each storage level further comprises: a first sub-chassis; a second sub-chassis, where first friction-reducing means are located between the first and second sub-chassis; and first elastic means that operatively connect each sub-chassis.a third subframe slidingly connected to the second subframe by means of a plurality of second friction-reducing means, wherein a plurality of second elastic means operatively connect the second subframe to the third subframe, wherein each of the elastic means comprises different stiffness or elasticity coefficients, wherein the elastic means with the lower stiffness coefficient, given that for light loads the elastic means with the lower stiffness coefficient (301) performs the dissipation function, while the elastic means with the higher stiffness coefficient (302) acts as a rigid element, and on the other hand, for heavy loads the elastic means with the higher stiffness coefficient (302) performs the dissipation function, while the elastic means with the lower stiffness coefficient (301) acts as a semi-rigid element, thanks to the displacement-limiting means (315),since the movement of the heavy mass would easily move the elastic medium with the lowest stiffness coefficient (301) until it reaches some stop or end of travel of the displacement limitation medium (315).,

[0042] APPLICATION EXAMPLES

[0043] The following are examples of applications of this utility model. These examples are provided for illustrative purposes only to provide a better understanding of the invention, but should in no way be considered as limiting the scope of the protection sought. Furthermore, specifications of different technical features described in the examples may be combined with each other, or with other technical features previously described, without limiting the scope of the protection sought.

[0044] EXAMPLE 1 STORAGE OF A “STANDARD” 225L WINE BARREL. TOTAL WEIGHT = 260KGF.

[0045] This barrel measures 70 cm in diameter and 95 cm in height, and is placed on a base measuring 85 cm x 120 cm. To protect this system from lateral loads, only one barrel can be stored per platform. The platform dimensions are 1 m x 2.50 m (width x height). This means the load can be distributed eccentrically across the platform.

[0046] Initially, each platform plate is designed with 4 rectangular tubular supports distributed around the perimeter and inside the platform, so that the equivalent elastic section modulus

[0047] Where:

[0048] Q: Storage load (kgf) h: Long dimension of the platform (cm)

[0049] Fy: yield strength of the material (kgf / cm²) 2 ) (commonly 3515 kgf / cm 2 )

[0050] Performing the tests, the support profile should be at least Sy=0.667cm 3 This results in profiles of 40 mm x 20 mm x 1.0 mm, although the minimum recommended size is 40 mm x 20 mm x 2.0 mm. Subsequently, for the design of the supports and supporting elements, it is considered that each MGN12H trolley withstands approximately 246 kgf, meaning that theoretically only two trolleys could support the load. However, to distribute the load considering the possibility of eccentric loads, two trolleys were used in the possible positions of the eccentric load; that is, two on each side and one in the center, resulting in a minimum of six trolleys per platform.

[0051] To design the isolation system, it is necessary to know the equivalent stiffness of the spring system. In this sense, the effectiveness of industrial seismic isolation depends on the ratio between the period of the structure and the isolated period. In this case, since the goal is to decouple the mass of the structure, the period ratio should always be above 1.5. This commonly implies an isolation period (Ta) between 2 and 3 seconds. Using basic dynamic relationships, the range of necessary equivalent stiffnesses is determined, considering that the stored mass may vary depending on the use.

[0052] This results in an equivalent stiffness (kev) between 1.31 N / mm and 2.96 N / mm. This must be distributed across at least two parallel spring systems per side to avoid torsional effects, requiring an equivalent stiffness ki = kev / 2. Furthermore, since each spring system consists of a pair of springs with different equivalent stiffnesses connected in series, and considering that the spring with the lower stiffness constant is 33.33% of the stiffness of the higher-stiffness spring, the equivalent stiffness of the larger spring (kma) is 4ki, and that of the smaller spring (kmi) is 1.333ki. For this case study, kma is between 2.63 N / mm and 5.92 N / mm, and kmi is between 0.877 N / mm. 2 and 1.97 N / mm 2 The stiffnesses kma and kmi can be obtained using the following equation which depends on the diameter of the spring used, the total number of turns, and the diameter of the spring wire, considering that the springs are made of steel or any elastic material.

[0053] For the present case, the kma spring was used considering an isolation period of 2.5s, resulting in a spring with an external diameter of 30 mm with a wire thickness of 3 mm, and a total of 13 total turns of the wire, so considering a travel of 75 mm, it would be a total length of 170 mm.

[0054] Furthermore, the kmi spring results in a spring with an outer diameter of 25 mm and a thickness of 2 mm, and a total of 10 turns. Considering a travel of 25 mm, this results in a spring length of 70 mm, achieving stability for this barrel, even with the applied lateral loads, where the displacement limiting mechanisms were not activated due to the barrel's low mass. This example is illustrated in Figure 13 with the barrel.

[0055] EXAMPLE 2 STORAGE OF A CHEVROLET VEHICLE. TOTAL WEIGHT = 1,092 KGF.

[0056] This vehicle measures 169.5 cm wide and 440.0 cm long. To protect this system from lateral loads, only one vehicle can be placed per platform or storage tray. The theoretical dimensions of the platform are approximately 2.0 m x 5.0 m (W x H). This means the load is concentrated eccentrically on the platform.

[0057] Each platform plate was designed with 4 rectangular tubular supports distributed around the perimeter and inside the platform, so that the equivalent elastic section modulus

[0058] Where:

[0059] Q: Storage load (kgf) h: Long dimension of the platform (cm)

[0060] Fy: yield strength of the material (kgf / cm²) 2 ) (commonly 3515 kgf / cm 2 )

[0061] Based on the calculations, the support profile must be at least Sy=2.43cm 3This resulted in profiles measuring 50 mm x 30 mm x 2.5 mm. Subsequently, the supports and elements were designed, considering that each MGN12H trolley can withstand approximately 246 kgf, theoretically allowing the use of 5 trolleys to support the load. However, the maximum length of the supports is around 1 m, so at least 4 supports per side must be used. Furthermore, given the load movement range of ±75 mm, at least 16 trolleys per side (2 per rail) are required to distribute the load properly. This resulted in a total of 32 trolleys being used per platform.

[0062] To design the isolation system, it is necessary to know the equivalent stiffness of the spring system. In this sense, the effectiveness of industrial seismic isolation depends on the ratio between the period of the structure and the isolated period. In this case, since the goal is to decouple the mass of the structure, the period ratio should always be above 1.5. This commonly implies an isolation period (Ta) between 2 and 3 seconds. Using basic dynamic relationships, the range of necessary equivalent stiffnesses is determined, considering that the stored mass may vary depending on the use.

[0063] This results in an equivalent stiffness (kev) between 4.79 N / mm and 10.78 N / mm. This must be distributed across at least two parallel spring systems per side to avoid torsional effects, requiring an equivalent stiffness ki = kev / 2. Furthermore, since each spring system consists of a pair of springs with different equivalent stiffnesses connected in series, and considering that the spring with the lower stiffness constant is 33.33% of the stiffness of the higher-stiffness spring, the equivalent stiffness of the larger spring (kma) is 4ki, and that of the smaller spring (kmi) is 1.333ki. For this case study, kma is between 9.58 N / mm and 21.55 N / mm, and kmi is between 3.19 N / mm. 2 and 7.19 N / mm 2 The stiffnesses kma and kmi can be obtained using the following equation which depends on the diameter of the spring used, the total number of turns, and the diameter of the spring wire, considering that the springs are made of steel or any elastic material.

[0064] In this case, the kma spring, considering an isolation period of 2.5s, consists of two springs with an external diameter of 40 mm and 3 mm thick wire, totaling 22 turns. With a travel of 75 mm, this results in a total length of 180 mm. The kmi spring, on the other hand, consists of two springs with an external diameter of 25 mm and a thickness of 3 mm, totaling 10 turns. With a travel of 25 mm, this results in a spring 70 mm long, achieving stability for the vehicle even under lateral loads. This is where the displacement limitation devices were activated, given the vehicle's mass. Figure 14 illustrates this example of the vehicle.
