输电线路六分裂导线展放所用滑车形式的研究

分析了输电线路六分裂导线展放过程对滑车的作用力,阐述了牵引绳和导线对滑车作用力大小、滑车的结构设计形式,对两种滑车结构受力情况和经济性进行了分析,认为采用多轴可改装式七轮滑车可以降低购置成本,提高经济效益.

Research on tackle type used for setting out six-multiple conductor in transmission line

The paper analyzed the countefforce against tackle when six - multiple conductor was set out, discussed the magnitude of force that pulling rope and conductor produced against tackle and described the tackle structure type. It also analyzed the countefforce situation and economy for two kinds of tackle, it is believed that the seven - wheel tackle with multiple shafts, which can be refit, can decrease the purchase cost, and in- crease economic benefit.
