It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0020] In one embodiment, see Figure 1-Figure 3 A building adjustable seismic support device comprises a support frame 1 and a support plate 2, wherein the support plate 2 is fixedly connected to the support frame 1 through a symmetrically distributed fixing plate 8, a first abutment plate 4 and a symmetrically distributed second abutment plate 5 are provided on the side of the support plate 2 away from the support frame 1, the first abutment plate 4 is fixedly connected to a first support rod 11, a first air cylinder 9 is passed through the interior of the support plate 2, the first air cylinder 9 is fixedly connected to the support plate 2, the first support rod 11 passes through the end of the first air cylinder 9 and is slidably connected to the end of the first air cylinder 9, a first elastic member 6 is provided outside the first support rod 11, and the two ends of the first elastic member 6 are respectively fixedly connected to the first abutment plate 4 and the support plate 2 The second support plate 5 is fixed with a second support rod 12, and a symmetrically distributed second air cylinder 10 is passed through the inside of the support plate 2. The second air cylinder 10 is fixedly connected to the support plate 2. The second support rod 12 passes through the end of the second air cylinder 10 and is slidably connected to the end of the second air cylinder 10. A second elastic member 7 is provided on the outside of the second support rod 12, and the two ends of the second elastic member 7 are respectively fixedly connected to the second support plate 5 and the support plate 2, wherein a switching mechanism 3 is provided between the first support rod 11 and the second support rod 12. When the vibration of the building reaches a certain degree, under the action of the switching mechanism 3, the first support plate 4 no longer supports the building, and the second support plate 5 starts to support the building.
[0021] In this embodiment, when the device supports the building, the support frame 1 drives the support plate 2 to move toward the building. On the one hand, the support plate 2 drives the first push plate 4 to move toward the building through the first air cylinder 9 and the first support rod 11, and on the other hand, drives the second push plate 5 to move toward the building through the second air cylinder 10 and the second support rod 12, until the first push plate 4 is tightly fitted with the building and squeezes the first elastic member 6, and the first elastic member 6 is in a compressed state. The first elastic member 6 elastically supports the building through the first push plate 4. The first elastic member 6 has lower stiffness and smaller bearing capacity, which is suitable for normal state or slight vibration, thereby providing initial stiffness and stability, and at this time the second push plate 5 is not in contact with the building. After the first push plate 4 supports the building, the support frame 1 can be fixed to the ground by bolts. When the vibration of the building reaches a certain degree, under the action of the switching mechanism 3, the first push plate 4 no longer supports the building The second elastic member 7 is used to elastically support the building through the second elastic member 7. The second elastic member 7 has high stiffness and large bearing capacity, which is suitable for strong earthquakes, thereby providing greater stiffness and energy absorption capacity, and ensuring the supporting effect on the building. The switching mechanism 3, the first elastic member 6 and the second elastic member 7 are set to adjust the supporting effect of the building, and can achieve graded response under different magnitudes. This design can effectively cope with earthquakes of different intensities, and can not only ensure the stability of the building under slight vibrations, but also provide stronger support and protection in strong earthquakes. The first elastic member 6 and the second elastic member 7 can both be springs, and the first air cylinder 9 has a limiting effect on the first support rod 11, and the second air cylinder 10 has a limiting effect on the second support rod 12, which effectively improves the stability performance of the first support rod 11 and the second support rod 12.
[0022] See also Figure 2-Figure 4The switching mechanism 3 includes a guide plate 34 fixed on the side wall of the support frame 1, a first positioning pin 32 is passed through the inside of the guide plate 34, a first stopper 35 is fixed to one end of the first positioning pin 32, and the first stopper 35 is connected to the guide plate 34 through a third elastic member 33, and the other end of the first positioning pin 32 is in contact with the side wall of the first support rod 11, wherein a first pin groove 31 adapted to the first positioning pin 32 is provided on the side wall of the first support rod 11, a guide cylinder 313 is fixed to the end of the first air pressure cylinder 9, the first support rod 11 passes through the guide cylinder 313 and is slidably connected to the guide cylinder 313, and a guide column 311 is fixed to the side wall of the guide cylinder 313 A second positioning pin 310 runs through the guide column 311, and a second pin groove 312 matched with the second positioning pin 310 is provided on the side wall of the second support rod 12. One end of the second positioning pin 310 is located in the second pin groove 312, and a second stopper 38 is fixed to the other end of the second positioning pin 310. The second stopper 38 is connected to the end of the guide column 311 through a fourth elastic member 39. A transmission assembly is provided between the second stopper 38 and the first stopper 35. When the first positioning pin 32 enters the first pin groove 31, the first stopper 35 pulls the second positioning pin 310 to the outside of the second pin groove 312 through the pulling assembly and the second stopper 38. When supporting the building, initially, the end of the second locating pin 310 is located inside the second pin groove 312 on the side wall of the second support rod 12 under the action of the second stopper 38 and the fourth elastic member 39, and the second locating pin 310 fixes the second support rod 12 through the second pin groove 312, and then fixes the second abutment plate 5. At this time, the second abutment plate 5 is not in contact with the building, and the second elastic member 7 is in a compressed state, and only supports the building through the first abutment plate 4. When the building vibrates, the building drives the first support rod 11 to vibrate through the first abutment plate 4, and the end of the first locating pin 32 slides on the surface of the first support rod 11. When the vibration amplitude of the building is large and the first support rod 11 moves to a certain extent, the first locating pin 32 is aligned with the first pin groove 31, and the first locating pin 32 is fixed to the first stopper 35 and the third elastic member 33. The second retaining plate 5 is moved to the outside of the second pin groove 312 by the traction assembly and the second stopper 38, and the second retaining plate 5 no longer fixes the second support rod 12. The second retaining plate 5 moves toward the building under the action of the second elastic member 7 until the second retaining plate 5 fits with the building. At this time, the second elastic member 7 is still in a compressed state. The second elastic member 7 supports the building through the second retaining plate 5, thereby providing greater rigidity and energy absorption capacity, thereby ensuring the supporting effect on the building. The third elastic member 33 and the fourth elastic member 39 can both be springs.
[0023] See also Figure 3 and Figure 4 The traction assembly includes a guide rod 36 fixedly connected to the support frame 1, a guide groove is passed through the guide rod 36, a traction rope 37 is passed through the guide groove, and both ends of the traction rope 37 are fixedly connected to the first stopper 35 and the second stopper 38 respectively; When the first positioning pin 32 enters into the first pin groove 31, the first positioning pin 32 pulls the traction rope 37 through the first stop block 35. Under the guidance of the guide groove, the traction rope 37 pulls the second positioning pin 310 to the outside of the second pin groove 312 through the second stop block 38, so that the second positioning pin 310 no longer fixes the second support rod 12, and the second elastic member 7 can support the building through the second support plate 5.
[0024] See also Figure 2 A first magnet 13 is fixed to one end of the first support rod 11 close to the support frame 1, and a second magnet 14 is fixed to the surface of the support frame 1. The magnetic properties of the first magnet 13 and the second magnet 14 are opposite; When the building vibrates with a large amplitude and the first support rod 11 moves to a certain extent, the first magnet 13 and the second magnet 14 at the end of the first support rod 11 attract each other. Under the mutual attraction between the first magnet 13 and the second magnet 14, the first support rod 11 continues to drive the first support plate 4 away from the building, so that the first support plate 4 cannot support the building until the first magnet 13 and the second magnet 14 are adsorbed together. When the first magnet 13 and the second magnet 14 are adsorbed together, the first positioning pin 32 is aligned with the first pin groove 31. The first positioning pin 32 automatically enters the first pin groove 31 under the action of the first stop block 35 and the third elastic member 33, thereby fixing the first support rod 11 and the first support plate 4.
[0025] See also Figure 2 , a stop rod 16 is fixed to the outside of the first support rod 11, and a control switch 15 is installed on the side of the support frame 1 close to the first support rod 11, and the control switch 15 is electrically connected to the alarm; When the first support rod 11 moves, it also drives the support rod 16 to move. When the first magnet 13 and the second magnet 14 are attracted together, the end of the support rod 16 just contacts the control switch 15. At this time, the control switch 15 controls the alarm (the alarm is not shown in the figure) to sound an alarm, thereby prompting people to pay attention, thereby playing a preventive role.
[0026] See also Figure 1 and Figure 3 A mounting frame 17 is fixed to the side of the support plate 2 away from the support frame 1, and a shock-absorbing airbag 18 is installed on the surface of the mounting frame 17. The shock-absorbing airbag 18 is connected to a first air pipe 19, and the other end of the first air pipe 19 is connected to the first air pressure cylinder 9. A first piston 20 is fixed to the outside of the first support rod 11, and the first piston 20 is slidably connected to the inner wall of the first air pressure cylinder 9; When the first support rod 11 moves, it also drives the first piston 20 to move inside the first air cylinder 9. When the first magnet 13 and the second magnet 14 are attracted together, the first piston 20 squeezes the gas inside the first air cylinder 9 into the shock-absorbing airbag 18 through the air pipe 19. At this time, the first shock-absorbing airbag 18 expands to the maximum extent. The building is supported by the first shock-absorbing airbag 18, which can further improve the earthquake resistance of the building.
[0027] See also Figure 4, an air column 21 is passed through the interior of the fixed plate 8, the air column 21 is fixedly connected to the fixed plate 8, the air column 21 is communicated with the second air cylinder 10, wherein an air rod 22 is passed through the end of the air column 21 away from the second air cylinder 10, the air rod 22 is slidably connected to the inner wall of the air column 21, a baffle 24 is fixed to the end of the air rod 22, the baffle 24 is connected to the fixed plate 8 through a fifth elastic member 23, a second piston 25 is fixed to the outside of the second support rod 12, and the second piston 25 is slidably connected to the inner wall of the second air cylinder 10; When the building vibrates with a large amplitude, the building drives the second support rod 12 to vibrate through the second abutment plate 5. The second support rod 12 vibrates and drives the second piston 25 to slide inside the second pneumatic cylinder 10. The second piston 25 slides and squeezes the gas inside the second pneumatic cylinder 10, so that the gas inside the second pneumatic cylinder 10 enters the air column 21 and pushes the pneumatic rod 22 to move. At this time, the fifth elastic member 23 buffers the pneumatic rod 22 through the baffle 24, which has a dispersing effect on the vibration generated by the building, further improving the earthquake resistance of the building. The fifth elastic member 23 can be a spring.
[0028] Working principle: When the device supports the building, the end of the second locating pin 310 is located inside the second pin groove 312 on the side wall of the second support rod 12 under the action of the second stop block 38 and the fourth elastic member 39. The second locating pin 310 fixes the second support rod 12 through the second pin groove 312, and then fixes the second abutment plate 5. At this time, the second abutment plate 5 is not in contact with the building, and the second elastic member 7 is in a compressed state. The building is supported only by the first abutment plate 4. When the building vibrates, the building drives the first support rod 11 to vibrate through the first abutment plate 4. The end of the first locating pin 32 slides on the surface of the first support rod 11. When the building vibrates to a certain extent, the first support rod 11 moves to a certain extent. At this time, the first magnet 13 and the second magnet 14 at the end of the first support rod 11 attract each other. Under the mutual attraction of the first magnet 13 and the second magnet 14, the first support rod 11 continues to drive the first abutment plate 4 away from the building, so that the first abutment plate 4 cannot support the building until the first magnet 13 and the second magnet 14 are adsorbed together and When the first magnet 13 and the second magnet 14 are attracted together, the first positioning pin 32 is aligned with the first pin groove 31, and the first positioning pin 32 automatically enters the first pin groove 31 under the action of the first stopper 35 and the third elastic member 33, thereby fixing the first support rod 11 and the first abutment plate 4, and the first stopper 35 moves while pulling the second positioning pin 310 to the outside of the second pin groove 312 through the traction rope 37 and the second stopper 38, and the second positioning pin 310 no longer fixes the second support rod 12, and the second abutment plate 5 moves toward the building under the action of the second elastic member 7 until the second abutment plate 5 fits the building, at which time the second elastic member 7 is still in a compressed state, and the second elastic member 7 supports the building through the second abutment plate 5, thereby providing greater rigidity and energy absorption capacity, and effectively regulating the supporting effect of the building, and can achieve graded response under different magnitudes. This design can effectively cope with earthquakes of different intensities, and can not only ensure the stability of the building under slight vibrations, but also provide stronger support and protection in strong earthquakes; In addition, when the first magnet 13 and the second magnet 14 are attracted together, the first piston 20 squeezes the gas inside the first pneumatic cylinder 9 into the shock-absorbing airbag 18 through the air pipe 19. At this time, the first shock-absorbing airbag 18 expands to the maximum extent. The first shock-absorbing airbag 18 supports the building, which can further improve the seismic resistance of the building. When the vibration amplitude of the building is large, the building drives the second support rod 12 to vibrate through the second abutment plate 5. The second support rod 12 vibrates and drives the second piston 25 to slide inside the second pneumatic cylinder 10. The second piston 25 slides and squeezes the gas inside the second pneumatic cylinder 10, so that the gas inside the second pneumatic cylinder 10 enters the air column 21 and pushes the pneumatic rod 22 to move. At this time, the fifth elastic member 23 buffers the pneumatic rod 22 through the baffle 24, which has a dispersing effect on the vibration generated by the building, further improving the seismic resistance of the building.
