碳纤维复合芯铝绞线的高塔放线滑轮
摘要：
本实用新型公开一种碳纤维复合芯铝绞线的高塔放线滑轮。包括固定架、滑轮组、缓冲弹簧和防震锤，固定架包括挂接杆和弧形支撑板，挂接杆垂直地设置在弧形支撑板的顶部，滑轮组包括主滑轮、左侧辅助滑轮和右侧辅助滑轮，主滑轮设置在所述弧形支撑板中间的下方位置，左侧辅助滑轮设置在主滑轮的左侧，右侧辅助滑轮设置在主滑轮的右侧，缓冲弹簧包括左侧拉伸弹簧和右侧拉伸弹簧，防震锤有两个，两个防震锤左右对称地固定在弧形支撑板左右两侧。本实用新型结构简单，能够增大碳纤维复合芯铝绞线经过高塔放线滑轮时所形成的剪切角，减少碳纤维复合芯铝绞线的芯棒受到的剪切损伤。
摘要（英）：

The utility model discloses a high tower wire-releasing pulley of a carbon fiber composite core aluminum twisted wire. The high tower wire-releasing pulley comprises a fixing frame, a pulley set, buffer springs and shockproof hammers. The fixing frame comprises a hanging rod and arc-shaped supporting plate. The hanging rod is vertically arranged at the top part of the arc-shaped supporting plate. The pulley set comprises a main pulley, a left side auxiliary pulley and a right side auxiliary pulley. The main pulley is arranged at the position below the middle of the arc-shaped supporting plate. The left side auxiliary pulley is arranged at the left side of the main pulley. The right side auxiliary pulley is arranged at the right side of the main pulley. The buffer springs comprise a left side extension spring and a right side extension spring. There are two shockproof hammers which are symmetrically fixed at the left and right sides of the arc-shaped supporting plate in a left-right direction. The high tower wire-releasing pulley is simple in structure, a shear angle formed by the carbon fiber composite core aluminum twisted wire in passing the high tower wire-releasing pulley can be increased and shear damage to the core rod of the carbon fiber composite core aluminum twisted wire can be reduced.
