The invention relates to a shock hammer. The device includes a short cast iron hammer and steel strand at both ends of the connection, in the short strand is connected with a clamp, end portion of the two cast iron hammer is connected with the extension spring, and the other end of the cable tension spring is connected to the internal tension spring is provided with two connecting together the oval ring ring both ends are respectively fixedly connected with the cable and the cast iron hammer. Due to the presence of spring tension spring, tensile energy absorption and flexible joint cast iron hammer through its elongation, so that the vibration of the cable and cast iron hammer vibration phase, effectively reduce the cable due to sloshing; ring, when the cable shaking amplitude exceeds the ultimate tensile spring adjustment, pull the cable with the cast iron hammer connection into a rigid connection, thereby effectively reducing the cable tension spring protection, shaking, to prevent the damage. The utility model can be used as an earthquake hammer, and is safe and reliable in use.

一种防震锤
本专利技术涉及电力金具制造
,特别涉及一种防震锤。
技术介绍
现有的中国专利数据库中公开了一种防震锤,其专利申请号为:201420328856.7,申请日为:2014.06.19,公告号为:CN203883427U,公告日为:2014.10.15,其结构包括有:钢绞线、线夹以及至少两个锤体,所述锤体固定安装在所述钢绞线的两端,其特征是:所述锤体上设有用于增大自身风阻的阻风面。其不足之处在于:由于该装置是通过增大防震锤的振幅和增加防震锤的震动频率,从而间接的中合电缆的震动幅度和频率,不能有效地减少电缆的震动,所以该装置的工作的有效性不稳定。
技术实现思路
本专利技术解决的技术问题是:在汲取和吸收现有防震锤技术的基础上,提供一种防震锤,该装置通过拉伸弹簧与拉环相配合,吸收电缆震动过程中的能量的同时中合电缆的震动幅度和频率,从而有效地减小电缆的震动。为了实现上述专利技术的目的,本专利技术所采取的技术方案:一种防震锤,包括一根短钢绞线和其两端连接的铸铁锤头,在短钢绞线上连接有夹线板,所述两铸铁锤头的端部连接有拉伸弹簧,拉伸弹簧的另一端与电缆相连接,拉伸弹簧的 ...
【技术保护点】
一种防震锤,包括一根短钢绞线和其两端连接的铸铁锤头,在短钢绞线上连接有夹线板,其特征在于:所述两铸铁锤头的端部连接有拉伸弹簧,拉伸弹簧的另一端与电缆相连接,拉伸弹簧的内部设有两连接在一起的椭圆形拉环,拉环的两端分别与电缆和铸铁锤头固定连接。
