[0020] Example 1
[0021] Such as figure 1 (Structural schematic diagram of a multi-directional displacement composite plate type telescopic device) As shown, the device is mainly composed of a displacement device 1 and a fixed plate 2. The fixed plate 2 is welded to the inner side beam 7 of the displacement device 1 by welding. One end of the fixed plate 2 is welded flush with the upper surface of the inner side beam 7 of the displacement device to form an integral structure. The support block 6 forms a force transmission fulcrum on the inner side, and the PTFE plate on the upper surface of the support block 6 and the fixed plate 2 form a sliding support point. The other side of the fixed plate 2 and the bridge deck are connected by bolts on the anchoring assembly. The anchoring assembly is composed of an anchor box 3, a compression rubber block 4 and a connecting bolt 5. The fixed plate 2 is embedded in the anchor box 3 through a boss at the bottom. The bottom of the boss and t...
