Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing structures, in particular to a shock-absorbing structure of a supporting platform. Background Art

[0002] A support platform is a structure specially designed to support and carry heavy objects or equipment. This type of platform is usually made of strong materials such as steel and concrete to ensure that it has sufficient strength and stability to bear the expected load. It has the characteristics of load-bearing capacity, stability, adaptability, safety, durability and convenience. In the fields of industrial production, warehousing and logistics, construction and so on, support platforms play an indispensable role.

[0003] Most existing support platforms have a relatively simple structure and do not have a shock-absorbing function. Therefore, when they are shaken by external factors such as earthquakes, the heavy objects on them may be subjected to a large impact and may even cause the heavy objects to fall. The falling of the heavy objects will not only damage themselves, but also pose a potential threat to nearby personnel or equipment, which is not practical. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A shock-absorbing structure for a supporting platform, comprising two sets of load-bearing plates and two sets of grounding frames, wherein the two sets of load-bearing plates are symmetrical to the two sets of grounding frames, and the load-bearing plates are located above the grounding frames, and further comprising:

[0010] Preferably, the rolling mechanism includes four groups of arc disks, and the four groups of arc disks are fixedly installed in pairs symmetrically on the bottom wall of the force-bearing plate near the two end edges and the top wall of the grounding frame near the two end edges. A group of cast steel balls are placed between the two groups of arc disks on the force-bearing plate and the two groups of arc disks on the grounding frame, and the outer walls of the cast steel balls are in contact with the inner walls of the arc disks on the force-bearing plate and the arc disks on the grounding frame respectively.

[0011] Preferably, upper permanent magnet plates are installed at the connection points between the two groups of arc disks located above and the force-bearing plates, and lower permanent magnet plates are installed at the connection points between the two groups of arc disks located below and the grounding frame.

[0012] Preferably, three groups of empty slots are provided at the bottom end of the grounding frame, the three groups of empty slots are connected to the mounting slots on the grounding frame, and reinforcing plates are installed on the three groups of empty slots, an anti-slip pad is installed on the top end of the force-bearing plate, and a group of empty slots is provided at the middle position of the bottom end of the force-bearing plate, the empty slots on the force-bearing plate are connected to the mounting slots on the force-bearing plate, and reinforcing plates are installed in the empty slots on the force-bearing plate.

[0013] Preferably, the first connecting mechanism includes two groups of sliding rails, and multiple groups of reserved holes are evenly penetrated on the outward side of the two groups of sliding rails, and first fixing nuts are provided in the multiple groups of reserved holes.

[0016] 1. The utility model sets a rolling mechanism between the load-bearing plate and the grounding frame. When the heavy objects on the load-bearing plate are shaken by external factors such as earthquakes, the cast steel balls roll in the upper and lower sets of arc disks (the grounding frame is fixed to the ground at this time) to make the load-bearing plate carrying the heavy objects start to move in the direction opposite to the shaking direction under the action of inertia.

When the cast steel ball moves in the upper and lower sets of circular arc disks, it can cut the magnetic flux lines generated by the upper and lower permanent magnetic plates, and convert the kinetic energy generated by the shaking into heat energy, thereby further improving the speed at which the entire structure returns to its original state, and further improving the stability and safety of the entire structure.

[0018] 3. The utility model can flexibly select the number of installed force blocks according to the number and size of the heavy objects to be placed by setting the installation grooves on the force-bearing plate and the grounding frame, thereby effectively improving the flexibility and adaptability of the entire structure. The setting of the reinforcement plates on the force-bearing plate and the grounding frame can improve the stability of the entire structure, so that it can better support and bear heavy objects.

[0019] 4. The utility model cooperates with the first connecting mechanism and the second connecting mechanism, and can utilize the reserved holes on the slide rail and the setting of the first fixing nut to add additional grounding frames and force plates to the initial force-bearing plate and grounding frame, thereby increasing the use area of ​​the initial grounding frames and force plates by adding grounding frames and force plates, thereby effectively improving the practicality of the entire structure. Since there are a large number of reserved holes on the slide rail, the distance between each group of grounding frames and force plates can be freely adjusted by adjusting the position of any group of grounding frames and force plates, thereby further improving the practicality of the entire structure.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figures 1 to 4 A shock-absorbing structure for a supporting platform includes two groups of force-bearing plates 6 and two groups of grounding frames 7. The two groups of force-bearing plates 6 are symmetrical with the two groups of grounding frames 7. The force-bearing plates 6 are located above the grounding frames 7. A rolling mechanism is provided on the force-bearing plates 6 and the grounding frames 7. The force-bearing plates 6 and the grounding frames 7 are connected by the rolling mechanism. The rolling mechanism is used to enable the force-bearing plates 6 above the grounding frames 7 to move stably. The rolling mechanism includes four groups of arc disks 12. The four groups of arc disks 12 are fixedly mounted on the force-bearing plates 6 in pairs. A group of cast steel balls 13 are placed between the two groups of arc disks 12 on the force-bearing plate 6 and the two groups of arc disks 12 on the grounding frame 7 near the edges of both ends of the bottom wall of the plate 6 and the top wall of the grounding frame 7. The outer walls of the cast steel balls 13 are in contact with the inner walls of the arc disks 12 on the force-bearing plate 6 and the arc disks 12 on the grounding frame 7 respectively. An upper permanent magnet plate 15 is installed at the connection between the two groups of arc disks 12 located above and the force-bearing plate 6, and a lower permanent magnet plate 14 is installed at the connection between the two groups of arc disks 12 located below and the grounding frame 7.

[0027] Reference Figures 1 to 2 , the side of the force-bearing plate 6 and the grounding frame 7 are penetrated with a mounting groove, and two groups of force blocks 11 are provided in the mounting grooves on the force-bearing plate 6 and the grounding frame 7, and multiple groups of second fixing nuts 9 are provided on the force blocks 11, and the force blocks 11 are detachably installed in the corresponding mounting grooves through multiple groups of second fixing nuts 9. The number of force blocks 11 installed on the force-bearing plate 6 and the grounding frame 7 can be selected according to the number and size of the heavy objects to be placed (for example, in this structure, two groups of force plates 6 are installed on the force-bearing plate 6 and the grounding frame 7), and three groups of empty slots are provided at the bottom of the grounding frame 7, and the three groups of empty slots are aligned with the mounting slots on the grounding frame 7 The grooves are interconnected, and reinforcing plates 10 are installed on the three groups of empty grooves. An anti-slip pad 5 is installed on the top of the force-bearing plate 6, and a group of empty grooves is opened in the middle position of the bottom end of the force-bearing plate 6. The empty grooves on the force-bearing plate 6 are connected to the installation grooves on the force-bearing plate 6, and reinforcing plates 10 are installed in the empty grooves on the force-bearing plate 6. The setting of the anti-slip pad 5 can increase the friction between the heavy objects placed on the force-bearing plate 6 and the force-bearing plate 6, preventing the heavy objects from sliding on the force-bearing plate 6, and thus avoiding the heavy objects from falling. The setting of the reinforcing plates 10 on the force-bearing plate 6 and the grounding frame 7 is used to improve the stability of the entire structure, so that it can better support and carry heavy objects.

[0028] Reference Figures 1 to 2, the two groups of force-bearing plates 6 are jointly provided with a first connecting mechanism at both ends, and the two groups of grounding frames 7 are jointly provided with a second connecting mechanism at both ends, which are respectively used to connect the two groups of force-bearing plates 6 and the two groups of grounding frames 7. The first connecting mechanism includes two groups of slide rails 2, and the two groups of slide rails 2 are evenly penetrated with multiple groups of reserved holes 3 on one side facing outward. The multiple groups of reserved holes 3 are each provided with a first fixing nut 4. Both ends of the two groups of force-bearing plates 6 are provided with a sliding groove 8. The two groups of slide rails 2 are fixed by the first fixing nut in the reserved hole 3 on them. The mother 4 can be detachably mounted in the slide groove 8 at both ends of the two groups of force-bearing plates 6. The second connecting mechanism includes two other groups of slide rails 2. The outward side of the other two groups of slide rails 2 is evenly penetrated with multiple groups of reserved holes 3. The multiple groups of reserved holes 3 are each provided with a first fixing nut 4. Slide grooves 8 are provided at both ends of the two groups of grounding frames 7. The other two groups of slide rails 2 can be detachably mounted in the slide grooves 8 at both ends of the two groups of grounding frames 7 through the first fixing nuts 4 in the reserved holes 3 thereon. A limit block 1 is fixedly installed at one end of the four groups of slide rails 2.

[0029] The number of grounding frames 7 and force plates 6 can be selected according to the placement requirements of heavy objects (for example, in this structure, the number of grounding frames 7 and force plates 6 are both two groups). First, the first group of grounding frames 7 and force plates 6 are moved to the position of the limit block 1 through the cooperation of the slide rail 2 and the slide groove 8. Then, the position of the first group of grounding frames 7 and force plates 6 is fixed through the reserved holes 3 on the slide rail 2 and the first fixing nut 4. Next, the second group of grounding frames 7 and force plates 6 are introduced by the slide rail 2. And so on. The use area of ​​the grounding frames 7 and force plates 6 can be increased by increasing the number of grounding frames 7 and force plates 6, thereby effectively improving the practicality of the entire structure. Since there are a large number of reserved holes 3, the spacing between each group of grounding frames 7 and force plates 6 can be freely adjusted by adjusting the position of any group of grounding frames 7 and force plates 6, thereby further improving the practicality of the entire structure.

[0030] When the heavy objects on the load-bearing plate 6 are shaken by external factors such as earthquakes, the cast steel balls 13 will roll in the upper and lower sets of arc disks 12, and the grounding frame 7 located below the cast steel balls 13 will not move. The load-bearing plate 6 carrying the heavy objects will begin to move in the opposite direction of the shaking under the action of inertia. This can effectively offset the impact of the shaking on the heavy objects, thereby effectively preventing the heavy objects from falling, and effectively improving the stability and safety of the entire structure.

[0031] At the same time, since the upper and lower arc disks 12 are respectively installed with an upper permanent magnet plate 15 and a lower permanent magnet plate 14 at the connection between the force-bearing plate 6 and the grounding frame 7, and the cast steel ball 13 is magnetic, the cast steel ball 13 will not shake for a long time under the attraction of the upper and lower magnetic forces, so that the cast steel ball 13 can be restored to its original state more quickly. When the cast steel ball 13 moves in the upper and lower sets of arc disks 12, it cuts the magnetic flux lines generated by the upper and lower permanent magnet plates 15 and the lower permanent magnet plates 14, and converts the kinetic energy generated by the shaking into heat energy. Converting kinetic energy into heat energy is an effective way of energy dissipation. This energy dissipation helps to slow down the movement speed of the object and make it tend to be stationary faster, that is, further improve the speed of the entire structure to restore to its original state. In summary, through the two mechanisms of magnetic attraction and kinetic energy conversion into heat energy, the entire structure can restore to its original state more quickly when subjected to external disturbances (such as earthquakes), thereby reducing the possibility of long-term shaking of the force-bearing plate 6, and further improving the stability and safety of the entire structure.

[0032] After the first and second fixing holes 3 are set, the first and second fixing holes 3 are set, and the fixing holes 3 are tightened to the first and second fixing holes 3. The fixing holes 3 are tightened to the first and second fixing holes 3. The fixing holes 3 are tightened to the first and second fixing holes 3.

[0033] After installation, place the heavy object on top of the force-bearing plate 6. The force-bearing plate 6 is installed with an anti-slip pad 5. The setting of the anti-slip pad 5 can increase the friction between the heavy object placed on the force-bearing plate 6 and the force-bearing plate 6, preventing the heavy object from sliding on the force-bearing plate 6, thereby avoiding the heavy object from falling. The setting of the reinforcement plate 10 on the force-bearing plate 6 and the grounding frame 7 can improve the stability of the entire structure, so that it can better support and carry heavy objects.

[0034] When the heavy objects on the load-bearing plate 6 are shaken by external factors such as earthquakes, the cast steel balls 13 will roll in the upper and lower sets of arc disks 12, and the grounding frame 7 located below the cast steel balls 13 will not move. The load-bearing plate 6 carrying the heavy objects will begin to move in the opposite direction of the shaking under the action of inertia. This can effectively offset the impact of the shaking on the heavy objects, thereby effectively preventing the heavy objects from falling, and effectively improving the stability and safety of the entire structure.

[0035] At the same time, since the upper and lower arc disks 12 are respectively installed with an upper permanent magnet plate 15 and a lower permanent magnet plate 14 at the connection between the force-bearing plate 6 and the grounding frame 7, and the cast steel ball 13 is magnetic, the cast steel ball 13 will not shake for a long time under the attraction of the upper and lower magnetic forces, so that the cast steel ball 13 can be restored to its original state more quickly. When the cast steel ball 13 moves in the upper and lower sets of arc disks 12, it cuts the magnetic flux lines generated by the upper and lower permanent magnet plates 15 and the lower permanent magnet plates 14, and converts the kinetic energy generated by the shaking into heat energy. Converting kinetic energy into heat energy is an effective way of energy dissipation. This energy dissipation helps to slow down the movement speed of the object and make it tend to be stationary faster, that is, further improve the speed of the entire structure to restore to its original state. In summary, through the two mechanisms of magnetic attraction and kinetic energy conversion into heat energy, the entire structure can restore to its original state more quickly when subjected to external disturbances (such as earthquakes), thereby reducing the possibility of long-term shaking of the force-bearing plate 6, and further improving the stability and safety of the entire structure.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
