Problems solved by technology

[0002] In recent years, with economic development and scientific and technological progress, in order to meet people's needs, more and more bridges cross mountains, heavy hills and deep ocean valleys, which brings new opportunities for the development of long-span steel bridges, cable-stayed bridges and suspension bridges. At the same time, it also brings a lot of challenges. One of the most important challenges is that the vibration caused by the wind will affect the stability of the bridge structure, cause the bridge to shake, affect the stability of the bridge, and shake for a long time will cause Bridge wear and tear, affecting service life

Embodiment 1

[0039] see figure 1 , the shock-absorbing and anti-sway damping device for suspension bridge wind resistance and its implementation method, comprising a fixed bridge pier 1, a main support pile 11 is fixedly installed above the fixed bridge pier 1, a bridge assembly 2 is fixed on the main support pile 11, and the main support pile 11 The upper end is connected to the support frame 12, and the two ends of the two sides of the support frame 12 are respectively provided with sling rods 3, and the sling rods 3 are connected by the shock absorbing device 4, and the sling fixing rod 5 is installed below the sling rod 3, and the sling The bottom of the fixed rod 5 is installed with the bridge component 2, and the anti-sway damping component 6 is connected between the sling fixed rods 5, and the reinforcement component 7 is arranged between the bottom of the main support pile 11 and the bridge component 2, and the pier 1 and the main support are fixed. Two groups of piles 11 are arran...

Embodiment approach

[0044] In order to better demonstrate the process of the anti-sway damping device for suspension bridge wind resistance, this embodiment proposes an implementation method for the anti-sway anti-sway damping device for suspension bridge wind resistance, including the following steps:

[0045] Step 1: The butt plates 22 are installed alternately, and the installed bridge components 2 are fixed on the main support piles 11, and the suspension rods 3 are fixed above the main support piles 11, and the shock absorbing device 4 is installed between the suspension rods 3 to install;

[0046] Step 2: When the wind is strong, apply pressure to the sling rod 3, and increase the pressure on the outer butt joint friction rubber strip 44 and the inner friction rubber strip 45 at the connection of the sling rod 3, so as to make the connection tighter, reduce shaking, and prevent misalignment;

[0047] Step 3: The sling fixing rods 5 are clamped by the inner connecting block 63 of the outer r...

Embodiment 2

[0049] see Figure 11 , the shock-absorbing and anti-sway damping device for suspension bridge wind resistance and its implementation method, comprising a fixed bridge pier 1, a main support pile 11 is fixedly installed above the fixed bridge pier 1, a bridge assembly 2 is fixed on the main support pile 11, and the main support pile 11 The upper end is connected to the support frame 12, and the two ends of the two sides of the support frame 12 are respectively provided with sling rods 3, and the sling rods 3 are connected by the shock absorbing device 4, and the sling fixing rod 5 is installed below the sling rod 3, and the sling The bottom of the fixed rod 5 is installed with the bridge component 2, and the anti-sway damping component 6 is connected between the sling fixed rods 5, and the reinforcement component 7 is arranged between the bottom of the main support pile 11 and the bridge component 2, and the pier 1 and the main support are fixed. There are two groups of piles ...
