An anti-fatigue device for the fixing position of an electrified railway cable comprises an elastic sheath, and a fixing arm is arranged at one end of the elastic sheath; wherein the elastic sheath is sleeved on the cable, the fixed arm is fixedly connected to a fixed part at the fixed part of the cable, the end part of the elastic sheath, which is connected with the fixed arm, extends into the fixed part, and the end part is in clearance fit with the fixed part. By sleeving the elastic sheath at the cable fixing position, the radial rigidity and the axial elasticity of the cable at the fixing position are enhanced, and the radial vibration amplitude of the cable is reduced in the vibration process, so that the fatigue resistance of the cable fixing position is improved.
一种电气化铁路线索固定处耐疲劳装置,包括弹性护套,所述弹性护套的一端具有固定臂;所述弹性护套套装在线索上,所述固定臂固定连接在线索固定处的固定部件上,并使弹性护套衔接固定臂的端部伸入固定部件中,且该端部与固定部件之间为间隙配合。本发明通过在线索固定处套装弹性护套,增强了固定处线索径向的刚性和轴向的弹性,使其在振动过程中减小线索在径向的振动幅度,从而提高线索固定处的耐疲劳性能。
