Abstract

The invention discloses a bridge damping device, which belongs to the field of bridges. The device comprises a plurality of supporting piers, and the tops of the supporting piers are fixedly connectedwith bridge decks; the bridge decks are in sliding connection with the supporting piers through bolts. Limiting sliding grooves located below the bridge decks are fixedly connected to the left side and the right side of the supporting piers correspondingly, limiting sliding blocks are slidably connected to the inner sides of the limiting sliding grooves correspondingly, rotating hinges are fixedly connected to the lower portions of the limiting sliding blocks, swing connecting rods are fixedly connected to the lower portions of the rotating hinges, and a bearing support is fixedly connected to the middle of each supporting pier. During use, damping is performed through the double damping devices, so that the damping effect is guaranteed; and when the vibration amplitude of the device is large, the swing connecting rods can drive gears to rotate, then first springs are compressed through transmission racks and sliding positioning blocks to conduct primary damping; meanwhile, damping supporting rods and horizontal damping bottom plates compress second springs to conduct further damping, vibration energy is thoroughly absorbed, and bridge safety is guaranteed.

Description

technical field

[0001] The invention relates to the field of bridges, in particular to a bridge damping device. Background technique

[0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head strap, conical slope protection, revetment, diversion engineering, etc...
