Abstract
Description
Technical Field
[0001] This utility model relates to the field of goods transportation, and in particular to a goods transportation device with dual-stage vibration reduction function. Background Technology
[0002] During the transportation of goods, the goods are subjected to continuous vibration and impact loads due to factors such as vehicle bumps and complex and changeable road conditions. This not only seriously threatens the integrity of the goods and transportation safety, but may also lead to irreversible losses such as failure of precision parts and damage to fragile items.
[0003] Currently, the industry commonly uses elastic materials such as foam pads and rubber blocks as cushioning media, which absorb some energy through their own deformation to achieve vibration reduction. However, existing solutions are mostly single flat plate structures, which are limited by the elastic coefficient and deformation range of the materials themselves. They are difficult to cope with high-frequency, multi-amplitude composite vibrations during transportation, especially in scenarios with severe road bumps or sudden braking, where the cushioning effect is greatly reduced, and there is still a high risk of damage to the goods.
[0004] Therefore, in view of the limitations of existing vibration reduction methods, it is necessary to develop a high-efficiency vibration reduction device that can achieve graded energy absorption and adaptive adjustment of vibration response through a two-stage buffer structure. This has important practical value for improving the safety of goods transportation and reducing loss rate. Utility Model Content
[0005] To effectively reduce the vibration and impact on goods during transportation, this application provides a goods transportation device with dual-stage vibration reduction function.
[0006] The technical solution of the goods transport device with dual-stage vibration reduction function provided in this application is as follows:
[0007] A goods transport device with dual-stage vibration reduction function includes a pallet, a plurality of spring vibration dampers, a plurality of rubber vibration dampers, and a chassis. The plurality of spring vibration dampers and the plurality of rubber vibration dampers are respectively installed between the pallet and the chassis. The plurality of spring vibration dampers and the plurality of rubber vibration dampers are distributed on the chassis at intervals. The plurality of spring vibration dampers are distributed at the four corners and the center of the chassis.
[0008] The tray is used to hold items.
[0009] The above technical solution combines springs and rubber shock absorbers, utilizing their synergistic effect to achieve a two-stage vibration reduction function. The first stage of vibration reduction utilizes the spring shock absorbers for low-frequency, small-amplitude impacts, and primarily provides load support under static loads. The second stage addresses occasional high-frequency, large-amplitude impacts during transport due to complex road conditions. In these situations, both the rubber and spring shock absorbers work together to significantly improve the vibration reduction effect, ensuring the goods are protected from vibration and impact damage during transport. Furthermore, the spaced-apart spring and rubber shock absorbers maximize their synergistic effect, achieving the two-stage vibration reduction function. Spring shock absorbers distributed at the four corners of the chassis help to evenly disperse and absorb vibrations and impacts from the ground, especially on uneven surfaces. The central spring shock absorber enhances the stability of the chassis center, effectively preventing swaying or instability caused by center-of-gravity shifts, particularly for large items. The spaced-apart rubber shock absorbers further enhance the vibration reduction effect.
[0010] Preferably, the spring damper includes two damping plates, multiple elastic columns, and multiple springs. The two ends of the elastic columns are fixedly mounted on the two damping plates. The multiple elastic columns correspond to multiple springs, and the springs are sleeved on the corresponding elastic columns. The two ends of the springs abut against the two damping plates, and the springs are evenly distributed on the damping plates. The two damping plates are fixedly mounted on the tray and the chassis, respectively.
[0011] Through the above technical solutions, the elastic column at the spring damper can also be made of rubber; the spring and the rubber elastic column complement each other, resulting in a better vibration reduction effect.
[0012] Preferably, the rubber vibration damper includes a pole and a rubber cylinder. The bottom end of the rubber cylinder and the bottom end of the pole are both fixedly mounted on the chassis. The rubber cylinder is sleeved on the outer periphery of the pole. The top end of the rubber cylinder and the top end of the pole are located on the same horizontal plane. When there is no external force, there is a gap between the top end of the rubber cylinder and the chassis.
[0013] Through the above technical solutions, the design of rubber vibration dampers utilizes the viscoelasticity and damping properties of rubber materials. When subjected to vibration, it undergoes elastic deformation and absorbs vibration energy. At the same time, the damping effect of rubber can further dissipate vibration energy. Furthermore, since spring vibration dampers and rubber vibration dampers have simple structures and high modularity, personalized devices can be quickly and temporarily made to deal with special structures, achieving more precise vibration reduction protection.
[0014] Preferably, a plurality of the elastic columns are arranged in a square structure, and the elastic columns located at the four corners and the center of the square structure have threaded holes on the side facing the tray; the damping plate near the tray is fixed to the elastic columns by bolt thread connection.
[0015] With the above technical solution, since there are many types of items with different shapes and different requirements for vibration reduction, the bolts can be unscrewed from the elastic column first, and the vibration damping plate near the pallet can be separated from the elastic column. Then, the vibration damping plate near the pallet can be removed, and other spring components can be replaced. This allows for personalized customization according to the characteristics of different items and transportation conditions, achieving more precise vibration reduction protection and improving the adaptability and flexibility of the device.
[0016] Preferably, the tray has multiple through holes arranged in a square and corresponding to bolts on a vibration damping plate fixed below the tray. The bolt heads are inserted into the through holes. The tray is threadedly connected to the vibration damping plate by screws passing through the through holes without bolt heads.
[0017] With the above technical solution, operators can unscrew all the screws and bolts through the through holes, thereby directly removing the tray and vibration damping plate at the same time, simplifying the disassembly process.
[0018] Preferably, the chassis is further provided with tie rods at the four corners, the bottom ends of the tie rods are fixedly mounted on the chassis, the tie rods are located between the tray and the chassis, and are used to bind steel cables.
[0019] Through the above technical solutions, in order for the transportation device to better provide vibration reduction for the transported goods, it is often necessary to use steel cables to fix the goods to the transportation device and vehicle. The design of the tie rod provides a convenient fixing point for the steel cable binding, which simplifies the operation process and improves the work efficiency during installation.
[0020] The main technical effects of this utility model are reflected in the following aspects:
[0021] 1. This utility model combines the use of springs and rubber dampers, utilizing their synergistic effect to achieve a two-stage vibration reduction function by combining the elastic deformation capacity of springs and the damping characteristics of rubber, thereby significantly improving the vibration reduction effect.
[0022] 2. This utility model utilizes the combined action of springs and rubber to reduce vibration, thereby reducing the increase in transportation costs. At the same time, since spring vibration dampers and rubber vibration dampers have simple structures and high modularity, personalized devices can be quickly and temporarily made to deal with items with special structures, achieving more precise vibration reduction protection.
[0023] 3. This utility model replaces springs of different elasticities with detachable damping plates, thereby enabling personalized customization according to the characteristics of different items and transportation conditions, achieving more precise vibration damping protection, and improving the adaptability and flexibility of the device.

[0030] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.
[0031] This application discloses a goods transport device with dual-stage vibration reduction function: (Refer to...) Figure 1-2 A two-stage vibration damping transport device includes a pallet 1, several spring vibration dampers 2, several rubber vibration dampers 3, and a chassis 4. The spring vibration dampers 2 and several rubber vibration dampers 3 are respectively installed between the pallet 1 and the chassis 4. The pallet 1 is used to carry the goods 9. By combining the springs 23 and the rubber vibration dampers 3, the two work together to achieve a two-stage vibration damping function. The first stage of vibration damping: for low-frequency, small-amplitude impacts, the spring vibration dampers 2 mainly provide the damping function. The second stage of vibration damping: during the transport of goods 9, due to the complexity of road conditions, occasional high-frequency, large-amplitude impacts may occur. At this time, the rubber vibration dampers 3 and the spring vibration dampers 2 jointly provide the damping function, significantly improving the damping effect and ensuring that goods 9 are not damaged by vibration and impact during transport.
[0032] Reference Figure 2The spring vibration damper 2 includes two damping plates 21, multiple elastic columns 22, and multiple springs 23. The two ends of the elastic columns 22 are fixedly mounted on the two damping plates 21. Each elastic column 22 corresponds to a spring 23, and the springs 23 are sleeved on their respective elastic columns 22. The two ends of each spring 23 abut against the two damping plates 21, and the springs 23 are evenly distributed on the damping plates 21. The two damping plates 21 are fixedly mounted on the tray 1 and the base 4, respectively. The elastic columns 22 in the spring vibration damper 2 can also be made of rubber; the springs and the rubber elastic columns complement each other, resulting in better vibration damping.
[0033] The rubber vibration damper 3 includes a vertical rod 31 and a rubber cylinder 32. The bottom end of the rubber cylinder 32 and the bottom end of the vertical rod 31 are both fixedly mounted on the base plate 4. The rubber cylinder 32 is fitted around the outer periphery of the vertical rod 31. The top end of the rubber cylinder 32 and the top end of the vertical rod 31 are on the same horizontal plane. When there is no external force, a gap exists between the top end of the rubber cylinder 32 and the base plate 1. The vertical rod 31 should also be made of rubber. The rubber vibration damper 3 utilizes the viscoelasticity and damping properties of rubber to undergo elastic deformation and absorb vibration energy when subjected to vibration. Simultaneously, the damping effect of the rubber further dissipates vibration energy.
[0034] While pursuing higher vibration reduction effects, cost factors must also be considered. Using vibration reduction devices with high-performance materials or complex structures alone may significantly increase transportation costs. However, this device reduces the increase in transportation costs by utilizing the combined action of spring 23 and rubber for vibration reduction. Furthermore, because spring vibration damper 2 and rubber vibration damper 3 have simple structures and a high degree of modularity, customized devices can be quickly and temporarily fabricated to specifically address items with special structures 9, achieving more precise vibration reduction protection.
[0035] Reference Figure 2 Several spring dampers 2 and several rubber dampers 3 are distributed alternately on the chassis 4. The spring dampers 2 and rubber dampers 3 arranged alternately can maximize the synergistic effect between the two, thereby realizing a two-stage vibration reduction function.
[0036] Several spring dampers 2 are distributed at the four corners and center of the chassis 4. The spring dampers 2 distributed at the four corners of the chassis 4 help to evenly disperse and absorb vibrations and impacts from the ground from all directions during vehicle operation, especially when encountering uneven road surfaces; while the spring damper 2 in the center enhances the stability of the chassis 4 center, and can effectively prevent swaying or instability caused by the shift of the center of gravity for large objects 9; the rubber dampers 3 are arranged at intervals with the spring dampers 2, forming two sets of opposite placement in the top and bottom and left and right directions.
[0037] Reference Figure 1-2Several elastic columns 22 are arranged in a square structure. Threaded holes 221 are provided on the side of the elastic column 22 facing the tray 1 at the four corners and center of the square structure. The damping plate 21 near the tray 1 is fixed to the elastic column 22 by bolts 5. Since the items 9 are diverse in type and shape, and their requirements for vibration damping are also different, different springs 23 with varying elasticity can be replaced by disassembling the damping plate 21. First, the bolts can be unscrewed from the elastic column 22, allowing the damping plate 21 near the tray 1 to detach from the elastic column 22. Then, the damping plate 21 near the tray 1 can be removed to replace the other spring components. This allows for personalized customization based on the characteristics of different items 9 and transportation conditions, achieving more precise vibration damping protection and improving the adaptability and flexibility of the device.
[0038] The tray 1 has multiple through holes 11 arranged in a square, corresponding to bolts 5 on the vibration damping plate 21 fixed below the tray 1. The screw heads of the bolts 5 are inserted into the through holes 11. The tray 1 is threaded onto the vibration damping plate 21 by screws 6 passing through the through holes 11 without screw heads inserted. The operator can unscrew all the screws 6 and bolts 5 through the through holes 11, thereby directly removing the tray 1 and the vibration damping plate 21 at the same time, simplifying the disassembly process.
[0039] Reference Figure 1-2 Each of the four corners of the chassis 4 is also fixed with a tie rod 7. The bottom end of the tie rod 7 is fixed to the chassis 4. The tie rod 7 is located between the pallet 1 and the chassis 4 and is used to bind the steel cable 8. In order for the transport device to provide better vibration reduction for the transported goods 9, it is often necessary to use the steel cable 8 to fix the goods 9 to the transport device and vehicle. The design of the tie rod 7 provides a convenient fixing point for binding the steel cable 8, simplifying the operation process and improving the work efficiency during installation.
[0040] Reference Figure 3-5 The steel cables 8 are secured as follows: First, multiple strands of steel cables 8 are used to secure the chassis 4 to the tie rods 7. Each tie rod 7 should have at least two strands of steel cables 8. One strand is perpendicular to the long side of the vehicle and secured to the tie rod 7, while the other end passes through the bottom of the vehicle and is also perpendicular to the long side of the vehicle and secured to a diagonally opposite tie rod 7. The other strand should be triggered from one of the four corners of the vehicle and secured to the corresponding tie rod 7. This restricts the tendency of the chassis 4 to move in all directions. Then, the item 9 is placed on the tray 1, and steel cables 8 are set parallel to the long side of the vehicle on the top surface of the item 9 to hold it firmly against the tray 1, allowing the vibration damping device to function effectively. Then, the steel cables 8 are set at an angle and in a crisscross pattern to restrict the horizontal movement of the item 9.
[0041] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
