Problems solved by technology

[0003] When the existing suspension bridge encounters cross wind, it will shake, which will cause damage to the bridge body, and also bring danger to pedestrians on the bridge. However, the auxiliary structures of the existing bridge cannot withstand cross wind Solving the problem of bridge shaking cannot reduce the degree of bridge shaking caused by cross wind

Embodiment 1

[0034] see figure 1 , The embodiment of the present invention provides a device for reducing the sway of a bridge caused by cross wind blowing, including a fixed buffer mechanism 1 and an anti-sway counterweight mechanism 2 , and the anti-sway counterweight mechanism 2 is movably installed on the fixed buffer mechanism 1 .

[0035] see figure 2 , the fixed buffer mechanism 1 is provided with a fixed installation frame block 11 and a buffer connector 12, the inner side of the fixed installation frame block 11 is fixedly installed with a buffer connector 12, and four groups of buffer connectors 12 are arranged, and the buffer connectors 12 of the four groups are respectively Tilted and fixedly installed at the inner four corners of the fixed installation frame block 11, forming a fixed buffer mechanism 1 as a whole, the fixed installation frame block 11 is provided with an arc groove block 111, a thickened fixed bar block 112 and an inclined surface groove 113, and the arc surf...

Embodiment approach ， 1 Embodiment approach

[0039] In order to further and better explain the above-mentioned embodiments, the present invention also provides an embodiment, a method for implementing a device for reducing swaying caused by cross-wind blowing of a bridge, comprising the following steps:

[0040] S01: Fix the fixed buffer mechanism 1 equipped with the anti-sway counterweight mechanism 2 to the lower end of the bridge through the installation connector 1121;

[0041] S02: When the cross wind blows the bridge and shakes, the arc groove block 111 follows the bridge and moves to the same side where the bridge shakes, and the counterweight 22 slides on the arc groove block 111 to the side opposite to the bridge shaking due to its own gravity , when sliding, the force generated by its own weight weakens or counteracts the force generated by the sway of the bridge, reducing the sway of the bridge;

[0042] S03: When the counterweight 22 slides on the arc-shaped groove block 111, the counterweight sphere 221 tilt...

Embodiment 2

[0045] see figure 1 , The embodiment of the present invention provides a device for reducing the sway of a bridge caused by cross wind blowing, including a fixed buffer mechanism 1 and an anti-sway counterweight mechanism 2 , and the anti-sway counterweight mechanism 2 is movably installed on the fixed buffer mechanism 1 .

[0046] see figure 2 , the fixed buffer mechanism 1 is provided with a fixed installation frame block 11 and a buffer connector 12, the inner side of the fixed installation frame block 11 is fixedly installed with a buffer connector 12, and four groups of buffer connectors 12 are arranged, and the buffer connectors 12 of the four groups are respectively Tilted and fixedly installed at the inner four corners of the fixed installation frame block 11, forming a fixed buffer mechanism 1 as a whole, the fixed installation frame block 11 is provided with an arc groove block 111, a thickened fixed bar block 112 and an inclined surface groove 113, and the arc surf...

Abstract

The invention discloses a device for reducing swaying caused by crosswind blowing of a bridge, which comprises a fixed buffer mechanism and an anti-sway counterweight mechanism. The anti-sway counterweight mechanism is movably installed on the fixed buffer mechanism. , the counterweight slides on the arc groove block to the opposite side of the bridge sway, the force generated by its own weight will weaken or offset the force generated by the bridge sway when sliding, reducing the bridge sway, the counterweight is in the arc groove After sliding on the block, the hydraulic telescopic rod pushes the counterweight to return to ensure the balance of the bridge. At the same time, it also discloses an implementation method of a device for reducing swaying caused by cross-wind blowing for bridges. When the counterweight slides on the arc-shaped groove block, the counterweight sphere tilts, and the liquid storage cavity opened inside the counterweight sphere The oil moves to one end of the liquid storage cavity of the bowl-shaped structure. When moving, the force F2 generated by the oil's own weight will weaken or offset the force F1 generated by the sliding of the counterweight sphere, so that the counterweight sphere returns quickly.

Description

technical field [0001] The invention relates to the technical field of anti-swaying equipment, in particular to a device for reducing swaying caused by cross-wind blowing of a bridge and an implementation method thereof. 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 provided at the support of the abutment. [0003] When the existing ...
