DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3The utility model discloses a combined splicing vibration reduction device, comprising a mounting base 1, a limiting enclosure 3 is arranged above the mounting base 1, a movable column 4 is arranged inside the limiting enclosure 3 away from the mounting base 1, a connecting column 5 is fixedly connected to the middle of the top side wall of the movable column 4, two slots 6 are arranged in the connecting column 5, and docking blocks 7 are inserted in the two slots 6, the docking blocks 7 are L-shaped structures, and the docking blocks 7 are detachably connected to the side wall at one end of the main beam joint, and a vibration reduction spring 8 is detachably connected to the middle of the bottom side wall of the movable column 4.

[0018] Four extension springs 15 are fixedly connected to the opposite side walls in the slot 6, one end of the extension spring 15 is fixedly connected to the push plate 14, and a telescopic limit plate 16 is fixedly connected to the four corners of the inner wall in the slot 6 and opposite to the push plate 14. The telescopic limit plate 16 is detachably connected to one side wall of the push plate 14 through one end, and the upper edge of the push plate 14 away from the telescopic limit plate 16 is established as an inclined structure, one end of the docking block 7 is inserted into the corresponding slot 6, and the two side edges of the bottom end of the docking block 7 located in the slot 6 are established as an inclined structure corresponding to the push plate 14, and the side wall of the docking block 7 located in the slot 6 is inlaid with an elastic pad.

[0019] The preferred technical effect of this solution is that when the two main beams vibrate or move due to the physical characteristics of thermal expansion and contraction, the docking block 7 will be driven to move synchronously. As the docking block 7 moves, it will push or pull the corresponding push plate 14 to move laterally according to its moving direction. The extension spring 15 can alleviate and offset the generated vibration, thereby improving the safety of the main beam application, avoiding large deformation of the joints of the main beam under vibration, and reducing the incidence of accidents on the bridge deck.

[0020] The damper 9 is detachably connected to the bottom side wall of the movable column 4 and near the edges on both sides. The damper 9 and the shock-absorbing spring 8 are detachably connected to the connecting plate 2 through their bottom ends. The limiting enclosure 3 is fixedly connected to the top side wall of the connecting plate 2 through its bottom end. A bottom groove 10 is opened at the top side wall of the mounting base 1 and opposite to the connecting plate 2. A shock-absorbing rubber plate 11 is fixedly connected to the bottom side wall in the bottom groove 10. An annular stopper 12 is fixedly connected in the bottom groove 10 and near the top edge. One end of the connecting plate 2 is telescopically inserted in the bottom groove 10, and the bottom side wall of the connecting plate 2 is fitted with the top side wall of the bottom groove 10. An anti-dropout block 13 corresponding to the stopper 12 is fixedly connected to the bottom edge of the connecting plate 2.

[0021] The preferred technical effect of this scheme is that when vibration occurs, the movable column 4 will rise and fall under pressure in the limiting enclosure 3, and the established shock-absorbing spring 8 can relieve and offset the pressure generated by the movement of the movable column 4. At the same time, the two established dampers 9 can cooperate with the shock-absorbing spring 8 and the movable column 4 to expand and contract synchronously. Because the damper 9 is a viscous damper 9 itself has a shock-absorbing effect, it can cooperate with the shock-absorbing spring 8 to improve the shock-absorbing effect. When the connecting plate 2 is subjected to pressure, it will be pressed into the bottom groove 10. At this time, the shock-absorbing rubber plate 11 is forced to shrink, which relieves and offsets the vibration pressure from the connecting plate 2, thereby improving the overall stability. While improving the shock-absorbing effect, it reduces the damage to the equipment caused by the pressure brought by the connecting plate 2.

[0022] Specifically, when the utility model is used, the mounting base 1 is first mounted on the pier, and the docking block 7 is pre-connected to the position specified by the main beam. When the main beam is connected to the pier, the docking block 7 is aligned with the slot 6, and then the docking block 7 is inserted into the corresponding slot 6 as the main beam descends. The push plate 14 and the top extension spring 15 set in the slot 6 are used to relieve and offset the vibration generated by the main beam, thereby preventing the main beam joint from being deformed and improving the safety of the bridge. The push plate 14 can be limited by the telescopic limit plate 16 set up, so that it can stably move in the horizontal direction to avoid the occurrence of safety accidents caused by its deflection. The damper 9 and the vibration-damping spring 8 are connected to the connecting plate 2, and the connecting plate 2 is inserted into the bottom groove 10 by snapping. The generated vibration can be greatly offset and alleviated by the cooperation of the vibration-damping spring 8 and the damper 9, and the transmitted vibration will be transmitted to the vibration-damping rubber plate 11 through the connecting plate 2, and the vibration can be alleviated by the elasticity of the vibration-damping rubber plate 11, thereby improving the safety of the bridge in vibration.
