Detailed Description
The utility model comprises a center support and four connecting arms circumferentially and uniformly distributed on the center support, wherein the center support comprises a base 2 and a top seat 3, the top seat 3 is rotatably arranged on the base 2 through a rotating shaft 4, the base 2 is arranged at the center position of the bottom of a communication tower through foundation bolts, a plurality of arc-shaped protruding blocks 5 are circumferentially and uniformly distributed on the lower end surface of the top seat 3, a plurality of arc-shaped grooves 6 are circumferentially and uniformly distributed on the upper end surface of the base 2, the arc-shaped grooves 6 are in one-to-one correspondence with the arc-shaped protruding blocks 5, two first pressure springs 7 are arranged between each group of arc-shaped protruding blocks 5 and the arc-shaped grooves 6, the upper ends of the two first pressure springs 7 are inclined towards the central line of the arc-shaped protruding blocks 5, namely, when the top block rotates, the first pressure springs 7 on one side are compressed, and the rotation of the top block is applied with reactive force to absorb energy and buffer, and meanwhile, the longitudinal shaking of the tower body can be buffered; four linking arms and four main steel one-to-one of communication tower, linking arm inner are fixed on footstock 3 lateral wall, are connected through second pressure spring 8 between linking arm outer end and the communication tower main steel, shake the level of communication tower through second pressure spring 8 and carry out the energy dissipation buffering, reduce its level range of rocking, when the body of the tower takes place to twist reverse, second pressure spring 8 can take place to crooked absorb a part of energy to shake the body of the tower and give footstock 3 through linking arm transmission.
The arc-shaped protruding blocks 5, the arc-shaped grooves 6 and the first pressure springs 7 are at least provided with four groups, so that enough buffering force can be ensured.
The center of each first pressure spring 7 is provided with a first limit post 9 fixed on the arc-shaped groove 6, the upper end of the first limit post 9 is not contacted with the arc-shaped convex block 5, and the first limit post 9 can avoid the displacement of the first pressure springs 7.
