DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a steel structure grid seismic reinforcement device includes a vertical tie rod 2 arranged vertically, a transverse tie rod 3 arranged horizontally, a steel ball 1 for connecting the transverse tie rod 3 and the end of the vertical tie rod 2, and a mounting base plate 5 for fixing the bottom of the vertical tie rod 2, a threaded column 7 is arranged at the bottom of the lower vertical tie rod 2, the lower end of the threaded column 7 passes through the mounting base plate 5 and extends to the bottom of the mounting base plate 5, a through hole 11 adapted to the threaded column 7 is arranged on the mounting base plate 5, the lower end of the threaded column 7 extends to the bottom of the mounting base plate 5 through the through hole 11, and the threaded column 7 is movably connected to the through hole 11, the outer side of the threaded column 7 located above the mounting base plate 5 is threadedly connected to a first nut 8, the outer side of the threaded column 7 located below the mounting base plate 5 is threadedly connected to a second nut 9, and the outer side of the threaded column 7 located between the first nut 8 and the mounting base plate 5 is sleeved with a first spring 10.

[0025] Furthermore, a cylinder 12 is arranged between the side wall of the lower end of the vertical rod 2 and the top of the mounting base plate 5, a piston rod 15 is movably arranged on the inner side of the upper end of the cylinder 12, and the upper end of the piston rod 15 is movably connected to the side of the vertical rod 2 through a first connecting seat 13, and the lower end of the cylinder 12 is movably connected to the top of the mounting base plate 5 through a second connecting seat 14, a partition 16 is arranged on the inner side of the cylinder 12, hydraulic oil 17 is stored on the inner side of the cylinder 12, two storage spaces for storing the hydraulic oil 17 are formed between the partition 16 and the piston rod 15 and between the partition 16 and the bottom of the inner cavity of the cylinder 12, a flow pipe 18 is arranged on the side wall of the cylinder 12, the flow pipe 18 is "U"-shaped, and both ends of the flow pipe 18 correspond to and are connected with the two storage spaces respectively.

[0026] Furthermore, a ring body 19 is fixedly connected to the outer side of the upper end of the piston rod 15 , and a second spring 20 is sleeved on the outer side of the upper end of the piston rod 15 , and the second spring 20 is located between the ring body 19 and the cylinder body 12 .

[0028] It should be noted that the utility model is a seismic reinforcement device for a steel structure grid. When the grid vibrates during use, the threaded column 7 moves downward to compress the first spring 10. The first spring 10 generates a reverse force to absorb part of the kinetic energy, and the piston rod 15 moves downward to squeeze the hydraulic oil 17. The hydraulic oil 17 enters the bottom of the partition 16 through the flow pipe 18. During this period, the flow of the hydraulic oil 17 generates resistance, thereby absorbing part of the kinetic energy. Moreover, when the piston rod 15 moves downward, it will drive the ring body 19 to compress the second spring 20, and then the second spring 20 can also absorb part of the kinetic energy. Multiple groups of shock-absorbing structures share the absorption of kinetic energy at the same time, which not only has high stability, but also can effectively buffer and reduce shock, thereby increasing safety. In addition, a reinforcement frame 4 is arranged between the relative tie rods 3, and workers can perform installation and fixing operations at the upper end. In addition, the tie rods 3 can be further reinforced to increase the structural strength.
