Description
技术领域
[0001] 本实用新型属于输电线路的架设工具，具体是一种碳纤维复合芯铝绞线的高塔放线滑轮。
背景技术
[0002] 随着电网建设的现代化发展，碳纤维复合芯铝绞线的应用越来越广泛。在碳纤维复合芯铝绞线的架设施工中，需要使用到高塔放线滑轮作为碳纤维复合芯铝绞线滑动前进的支点，但目前应用于碳纤维复合芯铝绞线的高塔放线滑轮仍然是沿用原来钢芯导线的高塔放线滑轮，结构没有任何改变，在实际施工中，发明人发现，碳纤维复合芯铝绞线的芯棒虽然在沿自身轴向上能够承受巨大载荷，但是其在径向上却只能承受很小的载荷，上述不同于钢芯导线的特性使得碳纤维复合芯铝绞线的芯棒容易在弯曲半径过小时发生碳纤维损伤或断裂，致使放线完毕后，达不到施工设计要求；在放线过程中发明人发现碳纤维复合芯铝绞线在高塔放线滑轮的进端和出端最容易形成弯曲，形成剪切角，这是因为传统的高塔放线滑轮适用于钢芯导线，无需考虑剪切角问题，所以传统的高塔放线滑轮的直径设计较小，导致导线形成狭窄的剪切角，所以容易损伤碳纤维复合芯铝绞线的芯棒。
实用新型内容
[0003] 本实用新型的目的是提供一种碳纤维复合芯铝绞线的高塔放线滑轮，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。
[0004] 本实用新型为解决其技术问题所采取的技术方案是，设计一种碳纤维复合芯铝绞线的高塔放线滑轮，其结构包括:固定架、滑轮组、缓冲弹簧和防震锤；所述固定架包括挂接杆和弧形支撑板，所述挂接杆垂直地设置在弧形支撑板的顶部，挂接杆的下端与弧形支撑板固定连接，挂接杆的上端设有带螺栓孔的固定板；所述滑轮组包括主滑轮、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，主滑轮通过连接板与弧形支撑板之间进行固定，所述左侧辅助滑轮设置在主滑轮的左侧，左侧辅助滑轮通过左侧连接臂与主滑轮之间进行连接，左侧连接臂一端与左侧辅助滑轮的转轴转动连接，另一端与主滑轮的转轴转动连接，所述右侧辅助滑轮设置在主滑轮的右侧，右侧辅助滑轮通过右侧连接臂与主滑轮之间进行连接，右侧连接臂一端与右侧辅助滑轮的转轴转动连接，另一端与主滑轮的转轴转动连接；所述缓冲弹簧包括左侧拉伸弹簧和右侧拉伸弹簧，左侧拉伸弹簧连接在左侧连接臂与弧形支撑板之间，右侧拉伸弹簧连接在右侧连接臂与弧形支撑板之间；所述防震锤有两个，两个防震锤左右对称地固定在弧形支撑板左右两侧。
[0005] 进一步地，所述主滑轮、左侧辅助滑轮和右侧辅助滑轮的直径相同，均为100〜120cm。
[0006] 进一步地，所述主滑轮、左侧辅助滑轮和右侧辅助滑轮上的滑轮凹槽内复合有耐磨橡胶层。
[0007] 本实用新型采用上述技术方案后，可通过固定架将本新型固定在高塔横担上。由于主滑轮、左侧辅助滑轮和右侧辅助滑轮径向排列组成一个滑轮组，碳纤维复合芯铝绞线在滑轮组的进端和出端形成的剪切角较大，弧形开阔，碳纤维复合芯铝绞线在滑轮组上所承受的剪切力很小，基本不会受到剪切损伤；滑轮凹槽内复合的耐磨橡胶层，一方面可以更好的贴紧导线，防止跳线，另一方面可以对导线进行有效保护，防止导线磨损；设置的缓冲弹簧可以使左右辅助滑轮对导线进行有效支撑，同时还能够释放导线在滑轮组进端和出端的自身应力，使进出角度更加平滑顺畅；设置的防震锤，可以有效降低放线过程中，滑轮组的风摆和颠簸。综上所述，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。
