DETAILED DESCRIPTION

[0034] Example

[0035] like Figure 1-6 As shown, a novel self-resetting energy-absorbing support device comprises a shell 2, and transmission parts are arranged through both side walls of the shell 2. A transmission device and an energy-absorbing device are arranged inside the shell 2. Energy is transmitted to the energy-absorbing device through the transmission device, and energy consumption is realized through the energy-absorbing device.

[0036] The device uses a viscous damper and a displacement amplification damper in combination, so that the viscous damper can be reciprocated within a limited stroke, which can prevent it from failing under rare earthquakes, thereby ensuring that the structure achieves good energy dissipation and shock absorption effects under all levels of earthquakes.

[0037] A multi-stage shock absorption method is adopted. When there is no external force or the external force is small, the main energy consumption device is separated from the central axis and does not work. When the force reaches a certain value, the main energy consumption device is connected to the central axis and works.

[0038] Further, the transmission member includes a first transmission member and a second transmission member, the first transmission member includes a first transmission rod 8, the first transmission rod 8 is connected to the first side wall of the housing 2, the first side wall is connected to the outside with a first connecting member 1-1, and the first transmission rod 8 is provided with teeth;

[0039] The second transmission member includes a second transmission rod 9, a connecting plate 4 is arranged in the outer shell, the second transmission rod 9 is connected to the connecting plate 4, the connecting plate 4 is connected to the second side wall of the outer shell 2 through multiple first memory alloy rods 7, a second connecting member 1-2 is arranged on the outside of the second side wall, and the second side wall is arranged opposite to the first side wall.

[0040] In this embodiment, the reset performance of the memory alloy rod can have a strong self-reset performance after an earthquake, thereby improving the utilization rate of the device.

[0041] Furthermore, the transmission device includes a central shaft system and a side shaft system, and the side shaft system is driven to rotate by the central shaft system.

[0042] A new type of self-resetting energy-absorbing support, the device is symmetrical up and down. The central axis 5 and the side axis 6 are divided into two layers, the inner layer is the axis, connected to the outer shell 2, and cannot rotate; the outer layer is the outer sleeve, the gear and the disc are fixed on it, and can rotate around the inner axis.

[0043] The first side wall of the housing 2 is connected to the first connecting member 1-1, and the second side wall of the housing 2 is connected to the first transmission rod 8. The left side of the connecting plate 4 is connected to the second transmission rod 9, and the right side is connected to the four first memory alloy rods 7 and the second connecting member 1-2, and the other end of the first memory alloy rod 7 is connected to the housing 2. The inner side of the other end of the rod 8 and the second transmission rod 9 is toothed and meshes with the middle shaft pinion 5-4. The viscous damper 16 is equipped with a piston plate 16-4, and the space enclosed by the piston plate 16-4 and its bottom is filled with viscous liquid. One end of the piston rod 10-4 is connected to the piston plate 16-4, and the other end is connected to the first disc 6-1 through the first connecting rod 12. The end of the first connecting rod 12 connected to the first disc 6-1 is connected to the housing 2 through the second memory alloy rod 13. The pulling and expanding device 11 is located between the two central axis gears, the second ring 11-2 and the first ring 11-4 are sleeved on the central axis 5, one end of the first steel cable 11-1 is connected to the first outer sleeve 5-1, and the other end is connected to the first seesaw 11-3 and the second seesaw 11-6.

[0044] The principle is as follows: when the device is subjected to a small force, the first connecting member 1-1 and the second connecting member 1-2 move relative to each other, driving the first transmission rod 8 and the second transmission rod 9 to move relative to each other. The first middle shaft gear 5-5, the second middle shaft gear 5-7 and the third middle shaft gear 5-4 are sleeved on the first outer sleeve 5-1, so that the second middle shaft gear 5-7 rotates, and the first outer sleeve 5-1 also rotates. The first steel cable 11-1 connected to the first outer sleeve 5-1 is wound around the first outer sleeve 5-1 as it rotates. The first steel cable 11-1 1 is pulled, and through the pulling and expanding device 11, the first ring 11-4 and the second ring 11-2 push the first middle shaft gear 5-5 to move along the central axis 5 toward the end, and the first spring 5-3 and the second spring 5-8 are compressed, but the force is small, and the first middle shaft gear 5-5 and the second middle shaft gear 5-7 do not move outward far enough and do not mesh with the first side shaft gear 6-2. At this time, the main energy consumption system does not work, and only the friction between the first transmission rod 8, the second transmission rod 9 and the second middle shaft gear 5-7 consumes energy. The relative movement of the first transmission rod 8 and the second transmission rod 9 will compress or stretch the four first memory alloy rods 7, and the memory alloy rods will deform, further consuming some energy. When the force is removed, the first memory alloy rod 7 returns to its original state, and the first spring 5-3 and the second spring 5-8 reset themselves, so that the system resets itself.

[0045] When the device is subjected to a large force, the first connecting member 1-1 and the second connecting member 1-2 move relative to each other, driving the first transmission rod 8 and the second transmission rod 9 to move relative to each other, causing the second central axis gear 5-7 to rotate, and the first outer sleeve 5-1 also rotates. The first steel cable 11-1 and the second steel cable 11-5 connected to the first outer sleeve 5-1 are wound around the first outer sleeve 5-1 as they rotate. The other end of the first steel cable 11-1 is pulled, and through the expansion device 11, the first ring 11-4 and the second ring 11-2 push the first central axis gear 5-5 and the second central axis gear 5-7 to move outward, and the first spring 5-3 is compressed. Due to sufficient force, the first central axis gear 5-5 moves a sufficient distance toward the end along the central axis 5, meshing with the first side axis gear 6-2 and the second side axis gear 6-5, and the main energy consumption system works. At this time, the first central axis gear 5-5 will cause the first side axis gear 6-2 meshing with it to rotate, and the rotation of the third central axis gear 5-4 will drive the second side axis gear 6-5 to rotate, and the first disc 6-1 and the second disc 6-7 coaxial with the first side axis gear 6-2 and the second side axis gear 6-5 will also rotate, and the two discs on the left and right sides have the same rotation direction. Finally, the first connecting rods 12 on the left and right sides push the piston rod 10-4, driving the piston plate 16-4 to reciprocate back and forth in the viscous damper 16, continuously squeezing the viscous liquid to make it move back and forth in the two chambers of the viscous damper 16, increasing energy consumption. At the same time, in the gear transmission, when the first middle shaft gear 5-5 rotates a certain angle, due to the relationship between the first middle shaft gear 5-5 and the first side shaft gear 6-2, and the third middle shaft gear 5-4 and the second side shaft gear 6-5, the first side shaft gear 6-2 and the second side shaft gear 6-5 will rotate a larger angle, increasing the number of times the piston plate 16-4 makes back and forth reciprocating motions in the viscous damper 16, and achieving greater energy consumption. When the force is removed, the first spring 5-3 and the second spring 5-8 reset themselves, pushing the first middle shaft gear 5-5 and the third middle shaft gear 5-4 back to their original positions, and the first middle shaft gear 5-5 and the first side shaft gear 6-2, and the third middle shaft gear 5-7 and the second side shaft gear 6-5 are no longer meshed, and the two parts reset themselves respectively. The second memory alloy rod 13 returns to its original state, causing the main energy consumption system to reset itself. The first memory alloy rod 7 returns to its original state, causing the middle system to reset itself.
