Description

[0002] In modern high-rise buildings, elevators have become indispensable vertical transportation tools. However, when an earthquake disaster occurs, the safety of elevators faces a severe challenge. The strong vibrations generated by the earthquake will cause the building to shake, twist and deform, which will in turn lead to the deformation of the elevator steel structure hoistway, resulting in the elevator car being stuck and the track being distorted and displaced, triggering serious accidents such as elevator falls.

[0003] Currently, most of the existing elevator steel structure hoistways adopt conventional steel frame structure designs, mainly focusing on meeting the load-bearing and space requirements for the daily operation of elevators, and their seismic resistance performance is generally insufficient.

[0037] Embodiment

[0038] As Figure 1 shown, a steel structure hoistway for an elevator with high seismic performance proposed by the present invention includes four groups of columns 1. A plurality of cross-columns 2 are connected between adjacent two groups of columns 1 to form a steel structure hoistway for an elevator, which is used for support, provides a stable frame structure for the operation of the elevator, and ensures the stability of the elevator during normal use.

[0039] Further, please refer to Figures 1 to 5, the above steel structure shaft includes fixing mechanisms 3 provided at both ends of the vertical column 1. The fixing mechanisms 3 are used to reduce the impact of earthquakes on the structure of the vertical column 1 and the horizontal column 2, and can effectively prevent the vertical column 1 and the horizontal column 2 from deforming and being damaged due to severe shaking during earthquakes, ensuring the integrity of the overall structure of the shaft. The fixing mechanism 3 includes a fixing frame 31 provided on the outer side of the vertical column 1. One end of the fixing frame 31 away from the vertical column 1 is installed with a fixing plate 32. Two groups of first buffer components 33 are provided in the fixing frame 31. The two groups of first buffer components 33 are orthogonally distributed and are used to buffer vibrations in two horizontal directions, and can disperse and weaken the seismic force in the horizontal direction, reducing the horizontal impact on the shaft structure. The first buffer component 33 includes a first moving block 331. Two groups of first limiting rods 332 are slidably connected in the first moving block 331. The first moving block 331 moves smoothly under the limiting action of the first limiting rods 332, ensuring that the first moving block 331 does not shift during the horizontal buffering process and guaranteeing the stability of the buffering effect. Both ends of the two groups of first limiting rods 332 are fixedly connected to a first installation frame 333. The first installation frame 333 is L-shaped. A groove 334 is opened on the side of the first moving block 331 away from the vertical column 1. A roller 335 is rotatably connected to the groove 334. The roller 335 is provided to support the first moving block 331 and is also convenient for movement, reducing the pressure of the first moving block 331 on the first limiting rods 332 after being affected by the gravity above, extending the service life of the first limiting rods 332, and improving the reliability of the buffer component. The first moving block 331 in one group of first buffer components 33 is fixedly connected to the first installation frame 333 in the other group of first buffer components 33. At the same time, the first moving block 331 in the other group of first buffer components 33 is fixedly connected to the vertical column 1. The two groups of first installation frames 333 are vertically arranged. Therefore, when an earthquake occurs, the vertical column 1 is affected by vibration and drives the first moving block 331 to slide on the first limiting rods 332, decomposing the vibration in the horizontal direction, and decomposing the complex horizontal seismic force into component forces in multiple directions, which is convenient for better buffering and absorption. Two groups of first springs 336 are sleeved on the outer circle of the first limiting rods 332. The two groups of first springs 336 are respectively arranged on both sides of the first moving block 331. Through the setting of the first springs 336, they are squeezed when the first moving block 331 moves, and then release elastic force to drive the first moving block 331 to reset, achieving the purpose of buffering vibrations, effectively absorbing and consuming the seismic energy in the horizontal direction, and reducing the damage of earthquakes to the shaft. A first rubber sleeve 337 is installed at the sliding fit position of the first moving block 331 and the first limiting rods 332. The first rubber sleeve 337 is sleeved on the outer circle of the first limiting rods 332. Through the setting of the first rubber sleeve 337, the friction force when the first moving block 331 slides is increased, effectively preventing the instability caused by the elastic force of the first springs 336 driving the first moving block 331 to reciprocate, and making the buffering process more stable and reliable.

[0040] Furthermore, the fixing mechanism 3 further includes second buffer components 34 installed at both ends of the two groups of first buffer components 33. The second buffer components 34 are used to buffer vibrations in the vertical direction, which can reduce the impact of the vertical impact force during an earthquake on the shaft structure and protect the vertical stability of the shaft. The second buffer component 34 includes a second moving block 341 fixedly connected to the side of the first mounting frame 333. When the first mounting frame 333 moves up and down, it drives the second moving block 341 to move synchronously. A plurality of second limiting rods 342 are slidably connected in the second moving block 341. The second moving block 341 moves smoothly under the limiting action of the second limiting rods 342, ensuring that the second moving block 341 remains stable during the vertical buffering process and improving the buffering efficiency. One end of each of the plurality of second limiting rods 342 is fixedly connected to the fixing plate 32, and the other ends of the plurality of second limiting rods 342 away from the fixing plate 32 are commonly fixedly connected to a positioning plate 343. The positioning plate 343 is fixedly connected to the fixing frame 31. The positions of the second limiting rods 342 and the positioning plate 343 are fixed, providing a stable support structure for the second buffer component 34. Two second springs 344 are sleeved outside the second limiting rods 342. The two second springs 344 are respectively arranged on both sides of the second moving block 341. Through the arrangement of the second springs 344, when the second moving block 341 moves, they are compressed, and then release elastic force to drive the second moving block 341 to reset, achieving the purpose of buffering vibrations and effectively absorbing and consuming the seismic energy in the vertical direction. A second rubber sleeve 345 is installed at the sliding fit position of the second moving block 341 and the second limiting rods 342. The second rubber sleeve 345 is sleeved outside the second limiting rods 342. Through the arrangement of the second rubber sleeve 345, the friction force when the second moving block 341 slides is increased, effectively preventing the instability caused by the reciprocating movement of the second moving block 341 driven by the elastic force released by the second springs 344 and ensuring the smoothness of the vertical buffering process.

[0041] Specifically, such as Figure 1 、 Figure 2 and Figure 6As shown in the figure, the above-mentioned steel structure hoistway further includes multiple groups of support mechanisms 4 installed outside the column 1. The support mechanism 4 is used to improve the stability of the column 1, enhance the ability of the column 1 to resist seismic forces, and prevent the column 1 from tilting or collapsing during an earthquake. The support mechanism 4 includes a fixed plate 41 fixedly connected to the side of the column 1. On the side of the fixed plate 41 away from the column 1, a support rod 42 is installed. A sleeve 43 is slidably sleeved on the outer circle of the support rod 42. A limiting plate 44 is slidably connected in the sleeve 43. The limiting plate 44 is fixedly connected to one end of the support rod 42 away from the fixed plate 41. The setting of the limiting plate 44 prevents the support rod 42 from detaching from the sleeve 43, ensuring the structural integrity and reliability of the support mechanism 4. Two groups of third buffer components 45 are provided at one end of the sleeve 43 away from the fixed plate 41. The two groups of third buffer components 45 are orthogonally distributed. A third spring 46 is sleeved on the outer circle of the support rod 42. The third spring 46 is arranged between the fixed plate 41 and the sleeve 43. The third buffer component 45 includes a third moving block 451. Multiple groups of third limiting rods 452 are slidably connected in the third moving block 451. The third moving block 451 moves smoothly under the limiting action of the third limiting rods 452, ensuring the stability of the third moving block 451 during the buffering process. Both ends of the multiple groups of third limiting rods 452 are fixedly connected to a second installation frame 453. The second installation frame 453 is L-shaped. The third moving block 451 in one group of third buffer components 45 is fixedly connected to the second installation frame 453 in the other group of third buffer components 45. At the same time, the third moving block 451 in the other group of third buffer components 45 is fixedly connected to the sleeve 43. The two groups of second installation frames 453 are vertically arranged. Thus, when an earthquake occurs, the column 1 is affected by vibration and drives the first moving block 331 to slide on the first limiting rod 332, decomposing the vibration. At the same time, one group of second installation frames 453 away from the column 1 is fixed to the inner wall of the elevator shaft, and together with the elastic force of the third spring 46, it supports the column 1, ensuring the stable position of the column 1 and further enhancing the seismic performance of the column 1. Two groups of fourth springs 454 are sleeved on the second installation frame 453. The two groups of fourth springs 454 are respectively arranged on both sides of the third moving block 451. Through the setting of the fourth springs 454, they are compressed when the third moving block 451 moves, and then release the elastic force to drive the third moving block 451 to reset, achieving the purpose of buffering the vibration. At the same time, the fourth springs 454 in the vertical direction support the column 1, reducing the pressure on the lower fixing mechanism 3 and improving the overall compressive performance, making the force of the hoistway during an earthquake more reasonable. A third rubber sleeve 455 is installed at the sliding fit position of the third moving block 451 and the third limiting rod 452. The third rubber sleeve 455 is sleeved on the outer circle of the third limiting rod 452. Through the setting of the third rubber sleeve 455, the friction force when the third moving block 451 slides is increased, effectively preventing the instability caused by the elastic force of the fourth spring 454 driving the third moving block 451 to reciprocate, ensuring the smoothness and reliability of the buffering process of the support mechanism 4.

[0042] In this embodiment, when an earthquake occurs, the elevator steel structure shaft of the present invention will work together through the fixing mechanism 3, the supporting mechanism 4 and each buffer component to achieve efficient earthquake resistance.

[0043] In the horizontal direction, the vibration caused by the earthquake will be transmitted to the column 1, driving the first moving block 331 in the fixing mechanism 3 to slide on the first limiting rod 332. Since the two groups of first buffer components 33 are orthogonally distributed, the vibration in two horizontal directions can be decomposed. When the first moving block 331 moves, it squeezes the first spring 336, and the first spring 336 absorbs and stores the vibration energy. When the vibration weakens, it releases the elastic force to drive the first moving block 331 to reset, thereby buffering the vibration in the horizontal direction. At the same time, the first rubber sleeve 337 between the first moving block 331 and the first limiting rod 332 increases the friction force to prevent the first moving block 331 from reciprocating due to the spring elastic force, ensuring the stability of the buffering process.

[0044] In the vertical direction, the vertical vibration generated by the earthquake causes the first mounting frame 333 to drive the second moving block 341 to move on the second limiting rod 342. The second moving block 341 moves to squeeze the second spring 344, and the second spring 344 absorbs the vibration energy in the vertical direction. After the vibration weakens, it releases the elastic force to drive the second moving block 341 to reset, realizing the buffering of the vertical vibration. The second rubber sleeve 345 also increases the friction force to avoid the reciprocating movement of the second moving block 341 and ensure the stability of the vertical buffering.

[0045] The supporting mechanism 4 also plays an important role in the earthquake. When the column 1 is affected by vibration, the supporting rod 42 slides in the sleeve 43, and the third spring 46 is compressed or stretched to absorb part of the vibration energy. At the same time, for the two groups of orthogonally distributed third buffer components 45, the third moving block 451 slides on the third limiting rod 452 and squeezes the fourth spring 454 to further decompose and buffer the vibration in the horizontal direction. The fourth spring 454 can not only buffer the vibration but also support the column 1 in the vertical direction, reducing the pressure on the lower fixing mechanism 3. The third rubber sleeve 455 increases the friction force to prevent the third moving block 451 from reciprocating, ensuring the stable and reliable buffering process of the supporting mechanism 4.

[0046] Through the coordinated operation of the fixing mechanism 3, the supporting mechanism 4 and each buffer component, the elevator steel structure shaft of the present invention can effectively buffer and decompose the vibration energy generated by the earthquake, reduce the damage of the earthquake to the elevator steel structure shaft, and ensure the safe operation of the elevator during the earthquake.

[0047] The above specific embodiments are only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
