Abstract
Description
Technical Field
[0001] This utility model belongs to the field of elevator safety technology, and in particular relates to an elevator installation buffer pile. Background Technology
[0002] Elevators may face various emergencies during operation, such as uncontrolled falls or rapid descents of the elevator car. The installation of buffer piles is to address these potential risks. When an elevator falls unexpectedly, the buffer piles can cushion the impact when the car reaches its bottom or top extreme positions. By absorbing the impact force of the car, they reduce damage to passengers inside the car and the elevator equipment itself, greatly improving the safety of elevator operation. They are a crucial part of the modern elevator safety system.
[0003] Currently, the buffer capacity of the buffer piles may still be insufficient in some extreme situations. For example, when the car falls at a very high speed, the existing buffer piles may not be able to completely eliminate the impact force, and may still cause some damage to the passengers and equipment inside the car. Once the actual impact force exceeds these design limits, the buffering effect will be greatly reduced. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1
[0027] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides an elevator installation buffer pile, including a base 1, and a vibration damping buffer mechanism 4 is provided above the base 1.
[0028] The vibration damping and buffering mechanism 4 includes a pile body 401, damping dampers 402, fixing blocks 403, limiting rods 404, limiting blocks 405, rubber blocks 406, supporting crossbars 407, limiting guide rails 408, limiting channels 409, stabilizing rods 410, and limiting seats 411. The limiting seats 411 are located at the bottom of the inner cavity of the pile body 401. The damping dampers 402 are located on the front and rear sides of the top of the limiting seats 411. The fixing blocks 403 are located at the top of the damping dampers 402. The supporting crossbars 407 are respectively arranged on both sides of the fixing blocks 403. The limiting rods 404 are adapted to... Installed on one side of the bottom of the support crossbar 407, the limiting block 405 is located at one end of the limiting rod 404, the rubber blocks 406 are fixedly installed on the front and rear sides of the top of the limiting block 405, the limiting guide rails 408 are evenly distributed on the front and rear ends of both sides of the inner cavity of the pile body 401, the limiting groove 409 is opened on the inner side of the limiting guide rail 408, the limiting block 405 is adapted to be installed in the inner cavity of the limiting groove 409, the end of the stabilizing rod 410 is fixedly connected to the top of the fixing block 403, and the front and rear sides of the stabilizing rod 410 and near the top are respectively fixedly installed with buffer round blocks 16.
[0029] like Figure 1-5As shown, the vibration damping and buffering mechanism 4 adopts a multi-stage buffering structure. In the initial buffering stage, when the elevator car impacts the pile 401, the damping vibration damper 402 located on the bottom limiting seat 411 of the pile 401 takes effect first. The damping vibration damper 402 can effectively absorb part of the impact force and dissipate the kinetic energy of the car into heat energy and other forms of energy. The limiting rod 404 and its end limiting block 405 connected to the supporting crossbar 407 through the fixed block 403 begin to participate in the buffering process. The rubber block 406 on the top of the limiting block 405 further increases the buffering effect. The elastic deformation of the rubber block 406 can absorb and disperse the impact force, and the rubber block 406... The presence of 6 can also reduce the damage caused by rigid collisions between components. At the same time, the limiting block 405 slides in the limiting groove 409 of the limiting guide rail 408, which not only ensures the directionality of the component movement during the buffering process, but also consumes energy through friction to a certain extent. Finally, the buffer circle 16 at the top of the stabilizing rod 410 serves as the final buffering link. When the impact force of the car is transmitted to this point, the buffer circle 16 can buffer the remaining impact force again. This multi-level buffering structure is progressive, absorbing, dispersing and dissipating the impact force from different angles and in different ways, thereby effectively protecting the elevator car and the passengers and equipment inside the car, and improving the safety of elevator operation.
[0030] Example 2
[0031] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0032] In this embodiment, mounting base plates 8 are respectively provided on both sides of the top of the base 1. Fastening bolts 9 are evenly distributed around the top of the mounting base plates 8. The fastening bolts 9 are threadedly connected to the base 1. The top of the stabilizing rod 410 is provided with an anti-impact and anti-collision mechanism 7. The anti-impact and anti-collision mechanism 7 includes a rubber damping pad 701, a disc 702, a coil spring 703, a connecting plate 704, a connecting rod 705, a connecting block 706, a buffer ring 707, a connecting disc 708, and a washer 709. The rubber damping pad 701 is located on the disc. At the bottom of the inner cavity of 702, there are five helical springs 703, which are evenly distributed on the top of the rubber damping pad 701. The connecting plate 704 is located on the top of the helical springs 703. One side of the bottom of the connecting rod 705 is adapted to the top of the connecting plate 704. The connecting block 706 is located on one side of the top of the connecting rod 705. The buffer ring 707 is located around the top of the disc 702. The bottom of the connecting disc 708 is fixedly connected to the top of the connecting block 706. The washer 709 is located on the surface of the top of the connecting disc 708.
[0033] like Figure 1 and Figure 4As shown, the fastening bolts 9 facilitate the secure installation of the mounting base plate 8. The rubber damping pad 701 first contacts the impact force, and with its good elasticity and damping characteristics, it initially absorbs and buffers the energy, reducing vibration transmission. Multiple helical springs 703 are evenly distributed on the rubber damping pad 701, forming a further buffering layer. They can store and consume more energy through their own elastic deformation on the basis of the buffering of the rubber damping pad 701, effectively dispersing the impact force. The connecting plate 704 connects the helical springs 703 to the connecting rod 705, ensuring the effective transmission of force. The buffer ring 707 can play an auxiliary buffering and protection role when subjected to lateral force or other irregular impact force. The washer 709 can protect and buffer the connecting parts above, preventing rigid collisions between parts. This structure works synergistically from multiple parts and levels, greatly improving the impact resistance and anti-collision capability of the buffer pile, ensuring the safe operation of the elevator.
[0034] Example 3
[0035] Reference Figure 1 , Figure 2 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0036] In this embodiment, support columns 2 are evenly distributed around the top of the base 1. A top plate 3 is fixedly installed at the top of the support column 2. A triangular support plate 5 is provided on one side of the top of the top plate 3, and an installation rod 6 is provided on the other side of the top of the top plate 3. A housing 12 is provided on the back of the top of the base 1. An exhaust hole 13 is opened on the back of the housing 12. A support column 14 is fitted on the top of the housing 12. Limiting strips 15 are fixedly installed on the front and rear sides of the support column 14. An auxiliary damping plate 10 is fixedly installed on the top of the support column 14. A buffer airbag block 11 is fixedly installed on the top of the auxiliary damping plate 10. A fixing tube 20 is fixedly connected to the end of the support column 14. A connecting tube 19 is sleeved on the surface of the fixing tube 20. An oil injector 21 is fixedly installed on the other end of the connecting tube 19. A limiting disc 18 is fixedly installed at the bottom of the fixing tube 20. An air spring 17 is fixedly installed at the bottom of the limiting disc 18. The end of the air spring 17 is fixedly connected to the bottom of the inner cavity of the housing 12.
[0037] like Figure 1 , Figure 2 and Figure 5As shown, the support column 2 supports the top plate 3, increasing the stability of the entire structure. The triangular support plate 5 and the mounting rod 6 can be used to connect other components or assist in fixing related equipment. The exhaust hole 13 facilitates internal air circulation and regulates pressure during the buffering process. The limit strip 15 ensures the stability of the support column 14 during operation and prevents it from shifting. The auxiliary damping plate 10 and the buffer airbag block 11 can absorb energy by utilizing the elastic deformation of the airbag when subjected to impact, playing a preliminary buffering and vibration reduction role. The setting of the fixed pipe 20, connecting pipe 19 and oiler 21 facilitates maintenance operations such as oiling inside the structure, ensuring the normal operation of related components. The air spring 17 can automatically adjust its elasticity and stiffness according to the pressure it receives. When subjected to a large impact force, it can absorb and release energy through the compression and expansion of the internal air. Together with the buffer airbag block 11 and other components, it forms a multi-level buffer structure, improving the buffering and vibration reduction capacity of the entire structure from multiple aspects, protecting the elevator equipment and enhancing safety.
[0038] In summary, by employing a multi-stage buffer structure, the vibration damping and buffering mechanism 4 absorbs, disperses, and dissipates impact forces from different angles and in different ways, thereby effectively protecting the elevator car and the passengers and equipment inside, and improving the safety of elevator operation. The buffer ring 707 can play an auxiliary buffering and protective role when subjected to lateral forces or other irregular impact forces. The washer 709 can protect and buffer the connecting parts above, preventing rigid collisions between parts. The air spring 17 can automatically adjust its elasticity and stiffness according to the pressure it receives. When subjected to a large impact force, it can absorb and release energy through the compression and expansion of the internal air. Together with the buffer airbag block 11 and other components, it forms a multi-stage buffer structure, which improves the overall structure's buffering and vibration reduction capabilities from multiple aspects, protecting elevator equipment and enhancing safety.
