As a main energy consuming component in this embodiment, wherein the buffer assembly comprises: a first elastic buffer element 13 and a second elastic buffer element 14. One end surface of the first elastic buffer member is connected with the first limiting plate 12, the other end surface is embedded in one end surface of the second elastic buffer member 14, and the other end surface of the corresponding second elastic buffer member is connected with the second limiting plate 15. In other words, the outer contour of the first elastic buffer element 13 closely conforms to the inner contour of the second elastic buffer element 14. The first elastic buffer member 13 is slidable within the inner wall of the inner ring layer 131 of the second elastic buffer member 14 by sliding friction.
For the above connection, as shown in fig. 3, the first elastic buffer member 13 has a cylindrical or inverted circular truncated cone shape, and is provided with a through hole in an axial direction, for example, a compression spring. The material of the first elastic buffer member 13, the inner race layer 131, and the outer race layer 133 is one or more of aluminum alloy or steel.

When the beam falling prevention device is in an operating state, the inner ring layer 131 of the second elastic buffer element 14 presses the first buffer layer 132 and the second buffer layer 135 on the outer side, so that the beam falling prevention device has double buffer effects and excellent buffer performance.
Example 3
As shown in fig. 11 and 12, the difference between this embodiment and embodiments 1 and 2 is that the first elastic buffer element 13 has a sandwich structure, and is divided into four parts, i.e., an inner ring layer 131, a first buffer layer 132, an outer ring layer 133, and a reserved cavity 134, where the inner ring layer 131, the first buffer layer 132, and the outer ring layer 133 are tightly bonded, and the reserved cavity 134 provides a deformation space for the buffer layer.

When an earthquake occurs, the beam bodies 5 are relatively displaced, so that the inhaul cable 2 is in a tight state, and the tension of the inhaul cable 2 drives the anchoring sleeve 3 and the fastening nut 4 to compress the buffering energy dissipation device, so that the buffering energy dissipation device plays a role in buffering energy dissipation.
The working principle is as follows: the compression assembly 11 and the first limiting plate 12 transmit pressure to the first elastic buffer element 13, so that the first elastic buffer element 13 is forced to be pressed into the second elastic buffer element 14, and in the process that the first elastic buffer element 13 moves in the second elastic buffer element 14, sliding friction energy dissipation occurs between the outer wall of the first elastic buffer element 13 and the inner ring layer 131 of the second elastic buffer element 14. Meanwhile, the first buffer layer 132 is forced to be deformed by extrusion, so that the stress of the inner ring layer 131 and the outer ring layer 133 can be improved due to the sufficient elastic deformation capability, and the buffer function is provided for the energy dissipation structure. The cavity at the bottom of the second elastic buffer element 14 can ensure the free deformation of the first buffer layer 132, so as to further ensure the buffer capacity of the first buffer layer 132.
