3. A method for implementing a device for reducing cross wind blowing generated shaking for a bridge according to any one of claims 1-2, characterized by comprising the following steps:
s01: fixedly mounting a fixed buffer mechanism (1) provided with an anti-sway counterweight mechanism (2) at the lower end of a bridge through a mounting connecting piece (1121);
s02: when the bridge is blown by cross wind to shake, the cambered groove block (111) moves to the same side of the bridge to shake along with the bridge, the counterweight (22) slides to one side of the opposite direction of the bridge to shake on the cambered groove block (111) due to the self gravity of the counterweight, and the force generated by the self gravity of the counterweight during sliding weakens or offsets the force generated by the bridge to reduce the shake of the bridge;
s03: when the counterweight member (22) slides on the arc-shaped groove block (111), the counterweight sphere (221) inclines, oil (22132) in a liquid storage cavity (22131) formed in the counterweight sphere (221) moves to one end of the liquid storage cavity (22131) of the bowl-shaped structure, and the force generated by the self weight of the oil (22132) during movement weakens or counteracts the force generated by the sliding of the counterweight sphere (221), so that the counterweight sphere (221) can return quickly;
s04: after the counterweight (22) slides on the cambered surface slot block (111), the hydraulic telescopic rod (121) pushes the counterweight (22) to return to ensure the balance of the bridge, or the second connecting spring (212) returns to push the counterweight (22) to return.
