The invention provides a dropper rope, a preparation method of an elastic dropper and an overhead line system. When the elastic dropper is prepared, multiple strands of ropes are obtained through a stranding process or a weaving process, and then the multiple strands of ropes are woven into the dropper rope through the weaving process, or multiple monofilaments are directly woven into the dropperrope. The obtained dropper rope has no central strand; each strand of the dropper rope can be uniformly stressed; each strand of rope and the vertical lifting stress direction of the dropper rope form a certain included angle, certain elasticity is achieved, impact force can be dispersed, the phenomena of bumps and the like are effectively avoided, the impact resistance elasticity of the overheadcontact system is enhanced, the fatigue service life of the overhead contact system is prolonged, and then the safety of high-speed railway electrified gas circuit operation is improved. Besides, during installation and use, the elastic dropper can be conveniently and reliably connected with a contact line and a carrier cable through fixing pieces at the ends, and the elastic dropper can be twisted to a certain extent, so that fine adjustment of the height is facilitated.

    本发明提出了一种吊弦线、弹性吊弦的制备方法及接触网,在制备弹性吊弦时,通过绞合工艺或编织工艺获得多股股绳后,再通过编织工艺将多根股绳编织成吊弦绳,或直接将多根单丝编织成吊弦绳。如此得到的吊弦绳没有中心股线,吊弦绳的每股股绳都能受力均匀,并相互约束,且每股股绳均与吊弦绳的垂直抬升受力方向呈一定夹角,具有一定弹性,能够分散冲击力,有效避免了鼓包等现象,增强了接触网抗冲击弹性,延长了接触网的疲劳使用寿命,进而提升了高速铁路电气化气路运行的安全性。另外,在安装使用时,弹性吊弦可以通过端部的固定件方便、可靠地与接触线和承力索连接,而且,弹性吊弦可以进行一定程度扭转,方便进行高度的微调。
