Description

Technical Field

[0001] This utility model relates to the field of bridge technology, specifically to a bridge shock-absorbing and buffering structure. Background Technology

[0002] Since the early 1970s, countries such as France, New Zealand, Italy, the United States, and Japan have begun to apply seismic isolation and damping devices to bridge construction. These countries have invested heavily in research on various types of seismic isolation and damping devices and design methods, achieving significant results. The application of seismic isolation technology in bridge structures can significantly improve the safety of bridges during earthquakes and reduce damage to bridge components. The excellent performance of seismic isolation and damping technology bridges in earthquakes has promoted the application of such bridges in practical engineering projects.

[0003] In existing bridge seismic damping systems, rubber damping blocks are attached to the blocks using adhesive or physical connections. However, investigations at multiple bridge sites have revealed that adhesive connections are prone to detachment as the adhesive ages, resulting in a widespread problem of rubber damping blocks falling off during installation (detachment rate of 15%–20%). Furthermore, adhesive installations are susceptible to environmental temperature fluctuations (bonding strength decreases by 40% when temperature fluctuations exceed 20℃). Physical connections often employ pre-embedded components within the blocks for anchoring, or use heavy-duty nail guns to directly fix the damping blocks to the blocks. Due to limited installation space, both adhesive and physical connections result in damping blocks that are either impossible to replace or extremely difficult to replace after reaching their service life. Utility Model Content

[0025] like Figure 4 As shown, the lifting mechanism includes a moving rod 17, a top plate 18, and a moving piece 16. The outer surface of the moving rod 17 extends through the interior of the positioning frame 3. The top plate 18 is installed at the top of the moving rod 17 and passes through the positioning frame 3. The moving piece 16 is installed at the bottom of the moving rod 17.

[0026] like Figure 4 As shown, the moving mechanism includes a moving block 12, a first connecting frame 13, a flipping column 14, and a second connecting frame 15. The moving block 12 is slidably connected to the connecting plate 7. The inner side of the moving block 12 is mounted on the outer side of the moving strip 11. The first connecting frame 13 is mounted on the upper surface of the moving block 12. The flipping column 14 is rotatably connected inside the first connecting frame 13. The second connecting frame 15 is rotatably connected inside the flipping column 14. The upper surface of the second connecting frame 15 is mounted on the lower surface of the moving piece 16.

[0027] like Figure 3As shown, the upper surface of the pre-embedded frame 2 is provided with a connecting groove 19. A connecting strip 20 is slidably connected inside the connecting groove 19.

A sealing cap 25 is sleeved on the outer surface of the fixing pin 24. A sealing gasket is installed on the lower surface of the sealing cap 25. The sealing gasket is sleeved on the outer surface of the fixing pin 24. The sealing cap 25 and the sealing gasket are used to seal the fixing pin 24 to prevent the fixing pin 24 from rusting after long-term use.

[0028] Working principle: When pouring the beam end back wall 1, the pre-embedded frame 2 is placed in the concrete and pre-embedded. The shock-absorbing pad 4 is slid in along the positioning frame 3, so that the shock-absorbing pad 4 moves downward and contacts the top plate 18 and drives it to move downward. The top plate 18 moves downward and drives the moving rod 17 to move downward. The moving rod 17 moves downward and drives the moving piece 16 to move downward. The moving piece 16 moves downward and drives the second connecting frame 15 to move downward. The second connecting frame 15 moves downward and drives the flipping column 14 to flip downward along the inside of the first connecting frame 13. The flipping column 14 flips downward and pushes the first connecting frame 13 inward. The first connecting frame 13 pushes inward and drives the moving block 12 to move inward. The moving block 12 moves inward and drives the moving strip 11 to move inward. The moving strip 11 moves inward along the connecting frame 9 and compresses the auxiliary spring 10. Manipulate the blocking plate 21 to slide the connecting strip 20 into the connecting groove 19, so that the blocking plate 21 moves to the upper surface of the shock-absorbing pad 4. Manipulate the blocking column 22 to move outward along the blocking plate 21. The outward movement of the blocking column 22 drives the blocking block 23 to move outward. After the movement is complete, manipulate the fixing pin 24 to insert into the blocking plate 21. Then rotate the fixing pin 24 clockwise to press against the blocking column 22. The shock-absorbing pad 4 is fixed by the reaction force of the auxiliary spring 10. The sealing cap 25 and the sealing gasket are put on the top of the fixing pin 24 to seal the fixing pin 24. The main beam 6 is hoisted onto the upper surface of the support base 5 using existing hoisting equipment, so that the side of the main beam 6 contacts the shock-absorbing pad 4, and then the main beam 6 is fixed to the support base 5 by welding. When the shock absorber pad 4 needs to be replaced after long-term use, the manipulator 21 slides the connecting strip 20 out along the connecting groove 19, causing the auxiliary spring 10 to rebound and drive the moving strip 11 to move outward. The moving strip 11 moves outward and drives the moving block 12 to move outward. The moving block 12 moves outward and drives the first connecting frame 13 to move outward. The first connecting frame 13 moves outward and drives the flipping column 14 to flip upward. The flipping column 14 flips upward and drives the second connecting frame 15 to move upward. The second connecting frame 15 moves upward and drives the moving piece 16 to move upward. The moving piece 16 moves upward and drives the moving rod 17 to move upward. The moving rod 17 moves upward and drives the top piece 18 to move upward. The top piece 18 moves upward and pushes the shock absorber pad 4 upward, so that the shock absorber pad 4 moves upward a certain distance along the positioning frame 3. The operator removes the shock-absorbing pad 4 for replacement, and then repeats the above operation to fix the shock-absorbing pad 4 in place.
