Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the present invention more comprehensible to those skilled in the art, and will thus provide a clear and concise definition of the scope of the present invention.
Fig. 1-9 show a double-layer damping platform structure according to this embodiment, which is a bottom structure of an elevator car. The platform structure comprises a platform 1, wherein the platform 1 is used for bearing the load of people or objects. The platform 1 comprises a platform support structure 19, a platform bottom plate 11 arranged on the platform support structure 19, a platform panel 18 arranged above the platform bottom plate 11, and a first damping component connected between the platform bottom plate 11 and the platform panel 18. The platform support structure 19 and the platform floor 11 are connected by screws. The first shock absorption assembly comprises a lower rubber plate 14, a lower partition plate 15, an upper rubber plate 16 and an upper partition plate 17 which are sequentially stacked from bottom to top. The lower rubber plate 14 is connected to the platform floor 11, and the upper partition 17 is connected to the platform panel 18. The lower partition plate 15 and the upper partition plate 17 are both galvanized plates. The lower partition 15 separates the upper rubber sheet 14 and the upper rubber sheet 16 from each other, and the upper partition 17 separates the platform panel 18 and the upper rubber sheet 16. When the platform panel 18 is stressed, the upper rubber plate 16 and the lower rubber plate 14 can be uniformly stressed through the split of the upper partition plate 17 and the lower partition plate 15. Through the above structural design, when shaking, go up rubber slab 14 and lower rubber slab 15 and play the cushioning effect to alleviate the vibration, these two sets of rubber slabs prevent that the noise from passing into in the car through the sedan-chair bottom 1 simultaneously.
The platform 1 described above comprises a platform frame. The car bottom frame is of a rectangular structure. The car bottom frame is connected to the car bottom base plate 11 through bolts and surrounds the outer sides of the peripheries of the first damping assemblies. The outer contours of the lower rubber plate 14, the lower partition plate 15, the upper rubber plate 16 and the upper partition plate 17 are matched with the inner contour of the platform frame. After installation, the outer peripheral walls of the lower rubber plate 14, the lower partition plate 15, the upper rubber plate 16, and the upper partition plate 17 are in contact with or in clearance fit with the inner peripheral wall of the platform frame, thereby restricting the above components in the platform frame.
The car bottom frame comprises a skirting board body 12 and a car door sill 13. The three groups of skirting board bodies 12 and the one group of car door sill 13 are mutually connected and combined into a car bottom frame. The car bottom frame comprises a skirting board body 12 and a car door sill 13 which are fixedly connected with a car bottom supporting structure 19 through bolts.
The lower rubber sheet 14 and the upper rubber sheet 16 of the present embodiment each include a plurality of divided bodies separated from each other. In the laying process, the respective components of the lower rubber sheet 14 are laid on the platform bottom surface 11 with a gap formed therebetween. The upper rubber plate 16 is laid on the lower partition plate 15 with a gap formed between the respective partitions. Through the arrangement mode, when the lower rubber plate 14 and the upper rubber plate 16 are compressed and deformed, the split bodies are provided with extension spaces, so that the lower rubber plate 14 and the upper rubber plate 16 cannot be crushed, and the service lives of the lower rubber plate 14 and the upper rubber plate 16 are prolonged.
The platform structure of the present embodiment includes a second damper assembly 2. The platform support structure 19 is mounted to the second damper assembly 2. The second damping components 2 are used for damping and cushioning the platform supporting structure 19. The second damper assembly 2 includes a bracket edge beam 21, a plurality of sets of springs 23 mounted on the bracket edge beam 21, and a receiving plate 22 mounted on the springs 23. Wherein the carrier edge beams 21 are fixed to the two sets of carrier back beams 3. The springs 23 are spaced apart along the length of the bracket edge beam 21. The bottom surface of the receiving plate 22 abuts against the top surface of each spring 23. The two sets of second damper assemblies 2 in this embodiment are arranged spaced apart from each other. The platform supporting structure 19 is fixedly connected with the bearing plates 22 of each group of second shock absorption assemblies 2 through bolts. The second damping assembly 2 comprises a limit bolt. A plurality of first matching holes 211 are processed on the bracket side beam 21 along the length direction at intervals, a second matching hole 221 is processed on the bearing plate 22 corresponding to the first matching holes 211, and a limiting bolt is movably inserted on the bearing plate 22 and the bracket side beam 21 at the corresponding position up and down, so that the bearing plate 22 is limited, and the bearing plate 22 is limited to move in the horizontal direction and only can move up and down.
In this embodiment, the second damper assembly 2 includes a rubber bushing 24. The rubber bush 24 is fitted to the outside of each set of springs 23, the bottom of the rubber bush 24 abuts against the bracket side member 21, and the top of the rubber bush 24 is not higher than the top of the spring 23 in a state where the platform 1 is not loaded. After the spring 23 is compressed to a certain height, the bearing plate 22 is abutted against the rubber bushing 24, and the rubber bushing 24 provides elastic acting force to further buffer the bearing plate 22, so that the spring 23 is prevented from being damaged due to overlarge deformation, and the service life of the spring 23 is effectively prolonged.
During the specific use, adopt rubber shock attenuation between 1 bottom plate at the bottom of the sedan-chair and the 1 panel at the bottom of the sedan-chair, can effectively block the noise and spread into the car through 1 at the bottom of the sedan-chair in the absorbing. Adopt a plurality of springs 23 shock attenuation between car bracket and the sedan-chair 1 bearing structure, can effectively filter mechanical shock, alleviate the vibrations sense of taking the car, effectively promote the travelling comfort that the elevator was taken.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
