this device has the level four shock attenuation, with the fixed setting of this device between wall body and steelframe, makes fabricated construction when experiencing the earthquake, steelframe and wall body fixed connection all the time, reduces because of the vibrations of earthquake with steelframe and wall body separation, the risk that leads to fabricated construction to collapse.
When earthquake intensity reaches the first preset intensity, the wall body does not shake due to an earthquake, the steel frame slightly shakes, and the first spring 3 fixedly arranged between the upper shell 1 and the lower shell 2 is compressed to buffer the steel frame vibration caused by the slight earthquake.
When the earthquake intensity reaches the second preset intensity, the wall body generates slight vibration, the vibration amplitude of the steel frame is increased, the first spring 3 is not enough to slow down the vibration of the steel frame at this time, the transmission plate 10 starts to vibrate under the driving of the steel frame, the transmission plate 10 is fixedly connected with the transmission parts 6 of the first shell and the second shell, so that the first shell and the second shell synchronously vibrate, as shown in the direction of figure 1, in the vibration process of the steel frame, the steel frame firstly moves upwards and moves downwards, in the upward movement process of the steel frame, the transmission part 6 of the first shell and the transmission part 6 of the second shell are driven to synchronously move upwards, as the shaft rod 101 penetrates through and is fixedly connected with the transmission part 6 of the first shell, under the driving of the transmission part 6 of the first shell and the transmission part 6 of the second shell, the shaft rod 101 starts to move upwards, the sliding block 105 which is rotatably connected with the shaft rod 101 through the connecting rod 104 slides in the sliding groove 501 arranged at the inner ends of the outer end covers of the sliding parts 5 of the first shell and the second shell, in the sliding part 5 of the first shell, the second spring 106 fixedly arranged between the sliding block 105 and the sliding groove 501 is compressed, and the second spring 106 in the sliding part 5 of the second shell is stretched, so that the second spring 106 stores energy to absorb the energy of the steel frame vibration caused by the earthquake; in the process of downward vibration of the steel frame, the lower shell 2 moves downward to compress the second spring 106 in the second shell, the second spring 106 in the first shell is stretched, and damping fluid is arranged in the closed space between the inner end cover of the transmission part 6 of the first shell and the inner end cover of the transmission part 6 of the second shell and the fixing sleeve 11, the transmission part 6 of the first shell and the transmission part 6 of the second shell move up and down under the driving of the transmission plate 10, so that the damping fluid is exchanged up and down on the fixing plate 112 of the fixing sleeve 11, and the energy of the earthquake with low efficiency gradually occurs.
When the earthquake intensity reaches the third preset intensity, the vibration amplitude of the steel frame is larger and larger, the up-and-down movement range of the transmission part 6 acting on the first shell and the transmission part 6 acting on the second shell through the transmission plate 10 is increased, and the up-and-down vibration range of the lower shell 2 is increased. When the amount of up-and-down movement of the shaft 101 is increased, the slide block 105 in the first housing or the second housing moves inwards to the limit position, but the upward or downward movement of the shaft 101 is not stopped, and as the shaft 101 continues to move, the slide part 5 of the first housing or the second housing is pulled to slide inwards, and because the inner side wall of the fixed sleeve 11 is provided with the elastic claw 4, when the slide part 5 slides inwards, the claw 4 only hinders the outward sliding of the slide part 5, so that the slide part 5 can only slide inwards. Because the shaft rod 101 is provided with threads, the rotating sleeve 7 is rotatably arranged on the inner end cover of the sliding part 5, and the rotating sleeve 7 is sleeved outside the shaft rod 101. The inward sliding of sliding part 5 drives and rotates cover 7, drive and rotate cover 7 and can only upper and lower sliding connection's transmission adapter sleeve 8 and rotate, the rotatable setting in fixed cover 11 of shutoff board 802 with transmission adapter sleeve 8 fixed connection, and during initial condition, the second through-hole of seting up on the shutoff board 802 aligns completely with the first through-hole of seting up on the fixed plate 112, make damping fluid smoothly pass through, along with rotating cover 7 and rotate and make shutoff board 802 rotate gradually, make first through-hole and second through-hole shutoff gradually, hinder the flow of damping fluid at fixed plate 112 upper and lower both ends.
When the earthquake intensity reaches the fourth preset intensity, the fixed cone 9 fixedly arranged in the middle of the shaft rod 101 moves along with the up-and-down movement of the shaft rod 101. The middle part of the fixing plate 112 is provided with a limiting block 117 and a limiting block 115, when in an initial state, the limiting block 115 prevents the limiting block 117 from sliding out of the limiting groove 114, when the up-and-down moving amplitude of the shaft rod 101 is increased, the maximum end of the fixing cone 9 contacts with the inner end of the limiting block 117, and the limiting block 117 is extruded to slide outwards. At this time, the elastic block 119 provided in the middle of the stopper 117 moves downward along the inclined block 116 of the stopper 115, so that the stopper 115 releases the blocking effect on the stopper 117, and the stopper 117 abuts against the inclined surface of the fixed cone 9 under the action of the first spring 3 to block the sliding of the fixed cone 9, thereby consuming the earthquake.
When the earthquake intensity reaches the third preset intensity, the instantaneous vibration of the shaft rod 101 can trigger the vibration-resisting movement of the device at the fourth-level preset intensity.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
