Description

Technical Field

[0001] This utility model relates to the field of bridge support technology, and in particular to a bridge seismic support device. Background Technology

[0002] In current technologies, seismic bracing is typically used in the support systems of bridges and other buildings, and is crucial for ensuring structural safety. However, seismic bracing devices such as anchors, blocks, and steel brackets, as well as seismic isolation bearings such as plate rubber bearings and lead-core rubber bearings, have limitations in their seismic resistance. Furthermore, the buffering of existing seismic bracing systems often relies on single buffer components such as springs or rubber, which are susceptible to aging due to environmental factors.

[0003] However, existing technologies still have shortcomings, such as the following:

[0004] Current earthquake-resistant technologies mostly rely on single cushioning components such as springs or rubber. These components are susceptible to aging due to environmental factors. Springs will experience elastic fatigue under long-term stress, while rubber is prone to cracking and hardening due to oxidation, thus losing its cushioning effectiveness. This not only shortens the service life of the earthquake-resistant system but also requires frequent component replacement, increasing maintenance costs and safety hazards. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 - Figure 4 As shown, a bridge-type seismic support device includes a support structure 1, and a seismic-resistant structure 2 is fixedly sleeved on the outer wall of the support structure 1. Sand and gravel are stored inside the seismic-resistant structure 2, and the gaps and friction between the sand and gravel particles provide a buffering effect when subjected to vibration. A sealing structure 3 is inserted into the inner side of the top of the seismic-resistant structure 2 to prevent sand and gravel from flying out of the inner side of the seismic-resistant structure 2 during vibration. A support structure 4 is installed on the outer wall of the support structure 1 and inside the seismic-resistant structure 2 for auxiliary support. The seismic-resistant structure 2 includes a sand storage box 21, and a drainage hole 22 is opened on the outer wall of the bottom of the sand storage box 21 for drainage. The top of the sand storage box 21 is... The bottom of the side is provided with a sandproof mesh 23 to prevent sand and gravel from leaking from the drainage hole 22. The outer wall of the sand storage box 21 is provided with a discharge groove 24, and a sealing baffle 25 is inserted into the inner side of the discharge groove 24, thereby sealing the discharge groove 24 through the sealing baffle 25. The sealing structure 3 includes a sealing splicing plate 31, and a threaded fixing block 32 is fixedly connected to the top of the sealing splicing plate 31. A fastening bolt 33 is threadedly connected to the inner side of the threaded fixing block 32, thereby merging the two halves of the sealing splicing plate 31 together through the fastening bolt 33. A rotating groove 34 is provided on the outer wall of one side of the sealing splicing plate 31 to facilitate the installation of the bracket body 41.

[0025] It should be noted that, in this embodiment, after the second fixed frame plate 43 is installed, the sealing baffle 25 is inserted into the discharge groove 24, and sand is added to the inner side of the top of the sand storage box 21. The sand particles are used to fill the gap between the support structure 4 and the secondary column 17. The gaps and friction between the sand particles also play a buffering role. The sandproof net 23 prevents the sand from leaking out from the drainage hole 22. Excess rainwater in the inner cavity of the sand storage box 21 is discharged through the drainage hole 22. After the sand is filled, the two half-sealing splicing plates 31 are assembled. The first fastening bolt 33 is passed through the sealing splicing plate 31 to fasten the sealing splicing plates 31 on both sides, forming a complete sealing splicing plate 31. The complete sealing splicing plate 31 is then placed over the upper surface of the sand storage box 21 to seal the sand and prevent leakage.

[0026] like Figure 1 - Figure 3 As shown, the support structure 1 includes a support column 11, and a threaded rod 16 is rotatably connected to the bottom of the inner side of the support column 11. A secondary column 17 is threadedly connected to the outer wall of the threaded rod 16 and located inside the support column 11. When the threaded rod 16 rotates, the secondary column 17 is limited by the support column 11 to slide upward or downward. A second inclined gear 15 is fixedly sleeved at the bottom of the outer wall of the threaded rod 16. The outer wall of the second inclined gear 15 meshes with the first inclined gear 14. An adjusting rod 12 is fixedly sleeved on the inner side of the first inclined gear 14. An iron rod is inserted into the adjusting groove 13 in the middle of the outer wall of the adjusting rod 12 and rotated, causing the adjusting rod 12 to rotate. This causes the first inclined gear 14 at both ends of the adjusting rod 12 to drive the second inclined gear 15 to rotate.

[0027] It should be noted that, in this embodiment, when the height of the secondary column 17 is adjusted, the second fixing plate 43 is placed inside the sand storage box 21, and the second fastening bolt 45 is passed through the secondary column 17 from the inside of the buffer plate 44 and threaded to the inside of the outer wall of the secondary column 17 and the inner side of the outer wall of the second fixing plate 43. Then, the positioning rod 452 is inserted into the inside of the positioning slot 451 to position and secure the second fastening bolt 45, thereby completing the installation of the second fixing plate 43.

[0028] like Figure 2 - Figure 4As shown, the support structure 4 includes a support body 41, and a first fixing plate 42 is rotatably connected to one end of the top of the support body 41 for fixing the structure to be supported. A second fixing plate 43 is rotatably connected to one end of the bottom of the support body 41. A second fastening bolt 45 is threadedly connected to the inner side of the second fixing plate 43. The second fixing plate 43 is fixed by the second fastening bolt 45. The outer wall of the second fastening bolt 45 is threadedly connected to the inner side of the outer wall of the secondary column 17. A buffer plate 44 is movably sleeved on the outer wall of the second fastening bolt 45 to withstand the vibration of the second fastening bolt 45 and reduce the direct damage to the secondary column 17. A positioning slot 451 is opened at one end of the outer wall of the second fastening bolt 45 and inside the second fixing plate 43. A positioning rod 452 is inserted into the inner side of the positioning slot 451 to limit the position of the second fastening bolt 45.

[0029] It should be noted that in this embodiment, by inserting the iron rod into the inner side of the adjusting groove 13 and then rotating it, the adjusting rod 12 is driven to rotate, and the two ends of the adjusting rod 12 drive the first inclined gear 14 to rotate. The outer wall of the first inclined gear 14 meshes with the second inclined gear 15, allowing the second inclined gear 15 to drive the threaded rod 16 to rotate. The outer wall of the threaded rod 16 is threadedly connected to the inner side of the secondary column 17, so that when the threaded rod 16 rotates, the secondary column 17 is limited by the support column 11 and moves upward, thereby increasing the installation angle of the bracket structure 4.

[0030] The working principle of this utility model is as follows: by inserting the iron rod into the inner side of the adjusting groove 13 and then rotating it, the adjusting rod 12 is driven to rotate, and the two ends of the adjusting rod 12 drive the first inclined gear 14 to rotate. The outer wall of the first inclined gear 14 meshes with the second inclined gear 15, and the second inclined gear 15 drives the threaded rod 16 to rotate. The outer wall of the threaded rod 16 is threaded to the inner side of the auxiliary column 17, so that when the threaded rod 16 rotates, the auxiliary column 17 is limited by the support column 11 and moves upward, thereby increasing the installation angle of the bracket structure 4.

[0031] When the height of the secondary column 17 is adjusted, place the second fixing plate 43 inside the sand storage box 21. At the same time, pass the second fastening bolt 45 through the inner side of the buffer plate 44 through the secondary column 17 and make a threaded connection with the inner side of the outer wall of the secondary column 17 and the inner side of the outer wall of the second fixing plate 43. Then insert the positioning rod 452 into the inner side of the positioning slot 451 to position and secure the second fastening bolt 45, thereby completing the installation of the second fixing plate 43.

[0032] After the second fixed frame plate 43 is installed, the sealing baffle 25 is inserted into the discharge trough 24. Sand and gravel are added to the inside of the top of the sand storage box 21. The flowability of the sand and gravel particles fills the gap between the support structure 4 and the secondary column 17. The gaps and friction between the sand and gravel particles also act as a buffer. The sandproof net 23 prevents the sand and gravel from leaking out of the drainage hole 22. Excess rainwater in the inner cavity of the sand storage box 21 is discharged through the drainage hole 22. After the sand and gravel are filled, the two half-sealing splicing plates 31 are assembled. The first fastening bolt 33 is passed through the sealing splicing plate 31 to fasten the sealing splicing plates 31 on both sides, forming a complete sealing splicing plate 31. The complete sealing splicing plate 31 is then placed over the upper surface of the sand storage box 21 to seal the sand and gravel and prevent leakage.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
