Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge supports, in particular to a spherical bridge support with a leveling function. Background Art
[0002] The purpose of leveling the spherical bridge bearings is to ensure that the bridge structure remains level in the face of foundation settlement, external loads, temperature changes, and structural deformation. By adjusting the height of the bearings, the bridge can be re-leveled, maintaining the stability and safety of the structure and extending the service life of the bridge. This leveling function can cope with various challenges, ensuring that the bridge remains stable and safe during operation, and providing reliable protection for people's travel.
[0003] The traditional spherical bridge bearing with leveling function is composed of components such as a spherical rotating part, a base, an upper seat plate, a leveling device, a sliding surface, a fixing device and possible elastic gaskets. These components work together to enable the bearing to rotate freely, adjust the height and maintain the level during the operation of the bridge, ensuring the stability and safety of the bridge structure, coping with challenges such as foundation settlement, external loads, temperature changes, etc., and extending the service life of the bridge.
[0004] However, the leveling mechanism structure of traditional spherical bridge bearings is relatively simple, and the traditional leveling process basically uses a spiral adjuster. Moreover, for this kind of leveling mechanism, it is necessary to consider that wear or rust of parts may affect its reliability, resulting in reduced leveling accuracy. Under harsh environmental conditions, such as high humidity or dusty areas, the spiral adjuster is susceptible to corrosion or blockage, affecting its normal operation. For bridges of special shapes or designs, the adjustment range of the spiral adjuster may not be sufficient to meet the requirements. Therefore, a spherical bridge bearing with a leveling function is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a spherical bridge bearing with a leveling function, including a base 1, a base 2 7 is fixedly connected to the top of the base 1, a damper 16 is arranged on the top of the base 2 7, a wedge block 15 is arranged on the outer wall of the damper 16, a slope column 13 is slidably connected to the top of the wedge block 15, a leveling bridge 14 is arranged on the top of the base 2 7, the wedge block 15 is slidably connected to the top of the base 2 7, a support assembly is arranged on the top of the base 2 7, and the support assembly includes a shell 6, and the bottom of the shell 6 is fixedly connected to the top of the base 2 7;
[0032] Specifically, when using a spherical bridge bearing with a leveling function, the top plate 2 applies pressure to squeeze the upper surface of the inclined column 13, so that the inclined column 13 is subjected to force through the inclined surface of the wedge block 15, and then the wedge block 15 slides at the bottom of the outer shell 6 and adaptively finds a balance point. During this process, the force applied from the top causes the internal leveling bridge 14 to shake. Since both sides of the leveling bridge 14 are provided with an interior where a hole is opened in the wedge block 15, an accurate leveling effect is achieved, thereby ensuring that the bridge bearing can adapt to various unbalanced loads, thereby improving the stability and safety of the entire bridge structure.
[0033] Reference Figure 1 and Figure 2 A first fixed block 3 is fixedly connected to the top of the base 1, a connecting block 17 is fixedly connected to the top of the first fixed block 3, a second rotating column 19 is rotatably connected to the inner wall of the connecting block 17, a second connecting rod 11 is rotatably connected to the outer wall of the second rotating column 19, one side of the second connecting rod 11 is rotatably connected to the first rotating shaft 8, one side of the first rotating shaft 8 is rotatably connected to the second rotating shaft 12, the outer wall of the second rotating shaft 12 is fixedly connected to the first connecting rod 10, one side of the first connecting rod 10 is rotatably connected to the first rotating column 18, the outer wall of the first rotating column 18 is rotatably connected to the connecting block 17, the top of the connecting block 17 is fixedly connected to the second fixed block 9, and a top plate 2 is provided on the top of the second fixed block 9.
[0034] Specifically, the second fixed block 9 is forced to move the first rotating column 18, and then the first connecting rod 10 is forced to move the second rotating shaft 12. The rotation of the sliding block 20 causes the sliding block 20 to move inside the hollow plate 5. Then the rotation of the sliding block 20 drives the first rotating shaft 8 on the outside to rotate, and then drives the second connecting rod 11 on the outer wall to rotate together, so that the second connecting rod 11 rotates inside the connecting block 17 to achieve a shock absorbing effect.
[0035] Reference Figure 2 The side wall of the second rotating shaft 12 is rotatably connected with a sliding block 20 , the sliding block 20 is slidably connected inside the hollow plate 5 , and the side wall of the hollow plate 5 is fixedly connected with a vacuum block 4 .
[0036] Specifically, subsequently, the top plate 2 is subjected to the pressure generated by the weight and is pressed on the top of the second fixing block 9 , causing the second fixing block 9 to apply pressure to the inside of the vacuum block 4 .
[0037] Working principle: When using the spherical bridge support with leveling function, the top plate 2 is pressed against the upper surface of the inclined column 13, and then the inclined column 13 is forced to level it on the surface of the wedge block 15, and the wedge block 15 is forced to slide on the bottom of the shell 6, and then it can adaptively find a balance point. At the same time, since the object is pressed on the top of the inclined column 13, the internal leveling bridge 14 is driven to shake. Because both sides of the leveling bridge 14 are arranged inside the hole opened in the wedge block 15, the leveling effect is achieved. Then, the top plate 2 is forced to press on the top of the second fixed block 9. Due to the second fixed block 9 is subjected to force and squeezed toward the inside of the vacuum block 4, and then the first rotating column 18 is driven to move by the second fixed block 9, and then the first connecting rod 10 is forced to drive the second rotating shaft 12 to rotate, and then the second rotating shaft 12 is rotated, and the second rotating shaft 12 is driven and the sliding block 20 slides inside the hollow plate 5 to move, and then the rotation of the sliding block 20 drives the first rotating shaft 8 on the outside to rotate, and then the rotation of the first rotating shaft 8 drives the second connecting rod 11 of the outer wall to rotate together, and the second connecting rod 11 is subjected to force to rotate inside the connecting block 17 to achieve a shock absorbing effect.
