The invention relates to the technical field of winches, in particular to a reciprocating type double-guide-rail vertical hydraulic winch which comprises a winch body used for winding a steel wire rope fixedly connected to one end of a whole bundle of steel strands and pulling the whole bundle of steel strands into a prestressed pipeline by winding the steel wire rope. The winch body is placed on a lifting type construction platform, when a steel wire rope is wound, the winch body falls on a buttress at the position of a prestressed pipeline opening, and the winch body is driven by the opposite acting force of the steel wire rope to be separated from supporting of the construction platform. According to the hydraulic winch, the whole bundle of steel strands can be pulled in at a time, and fixing is not needed.
本发明涉及卷扬机技术领域,尤其涉及一种往复式双导轨立式液压卷扬机,包括:卷扬机本体,所述卷扬机本体用于收卷固定连接在整束钢绞线一端上的钢丝绳,通过收卷钢丝绳将整束钢绞线拉入预应力管道内,所述卷扬机本体放置在可升降式施工平台上,在收卷钢丝绳时,所述卷扬机本体落于预应力管道口处的扶壁柱上,所述卷扬机本体在钢丝绳反向作用力驱动下脱离施工平台的支撑。本发明提供了一种能够一次性拉入整束钢绞线且无需固定的液压卷扬机。
