本发明公开了一种悬索桥主缆索夹用橡胶弹簧密封条，包括上安装部、下安装部和弹性部，弹性部包括对称布设的上弹性部和下弹性部，上弹性部包括第一长条形空心弹性体和第一封堵块，第一长条形空心弹性体包括空心弹性体本体，空心弹性体本体包括上平直部和下平直部，以及对称设置在上平直部左右两侧的左弧形部和右弧形部。本发明设计新颖合理，弹性部由至少两个空心弹性体本体组成，每个空心弹性体本体的压缩量可达到65％，且在空心弹性体本体的压缩量达到65％时，仅仅是将空心弹性体本体压合在一体，空心弹性体本体并未受到压缩产生变形，对提高该橡胶弹簧密封条的寿命起到了积极的作用，压缩量大，密封效果好，使用寿命长。

The invention discloses a rubber spring sealing strip for a main cable clamp of a suspension bridge, which comprises an upper mounting part, a lower mounting part and an elastic part, the elastic part comprises an upper elastic part and a lower elastic part which are symmetrically arranged, the upper elastic part comprises a first strip-shaped hollow elastic body and a first plugging block, and the first strip-shaped hollow elastic body comprises a hollow elastic body main body; the hollow elastomer body comprises an upper straight part, a lower straight part, and a left arc-shaped part and a right arc-shaped part which are symmetrically arranged on the left side and the right side of the upper straight part. The design is novel and reasonable, the elastic part is composed of the at least two hollow elastomer bodies, the compression amount of each hollow elastomer body can reach 65%, when the compression amount of the hollow elastomer bodies reaches 65%, only the hollow elastomer bodies are pressed together, the hollow elastomer bodies are not compressed to generate deformation, and the elastic part is not prone to deformation. The rubber spring sealing strip plays a positive role in prolonging the service life of the rubber spring sealing strip, and is large in compression amount, good in sealing effect and long in service life.
