The invention provides a segmented combined winch drum for south pole subglacial lake drilling, and belongs to the field of drilling machines and tools, the segmented combined winch drum comprises a drum body, a transmission mechanism and a traverse unit block, the drum body comprises at least two coaxially connected drum units, each drum unit comprises a drum outer pipe, a drum and a guide rail, the drum is arranged in the drum outer pipe, and the guide rail is arranged in the drum outer pipe. All the winding drums in the winding drum body rotate synchronously, so that the cable is wound or released on the winding drums along with the rotation of the winding drums; the cable arranging device block is used for driving a cable to be wound or released on the winding drum in the mode that the cable arranging device block reciprocates up and down along a guide rail in the winding drum unit, and the transmission mechanism drives the cable arranging device block to move up and down in the winding drum along the guide rail. According to the invention, each part of the winding drum is modularized through the modular design, so that the winding drum of the winch is prevented from being bent due to overlarge length, a large-length cable is prevented from being released, the hot melt detector can be drilled to a deeper depth, and the working reliability of the hot melt detector is improved.
本发明提出了一种南极冰下湖钻探用分段组合式绞车卷筒,属于钻探机具领域,包括卷筒体、传动机构和排线器块,卷筒体包括至少两个同轴连接的卷筒单元,每个卷筒单元包括卷筒外管、卷筒和导轨,卷筒设置在卷筒外管内,卷卷筒体中所有卷筒同步旋转,从而使得线缆随着卷筒的旋转进而在卷筒上缠绕或释放;排线器块用于以沿着卷筒单元中的导轨上下往复运动的方式带动线缆在卷筒上缠绕或释放,传动机构带动排线器块在卷筒内沿着导轨做上下运动。本发明通过模块化设计将卷筒各部分模块化,防止由于长度过大造成绞车卷筒弯曲,大长度线缆释放的功能,可以使热融探测器钻进到更深的深度,提高了其工作可靠性。
