摘要
偏心配水器投捞器是一种与配水器配套使用的井下工具，用于对偏心配水器中的堵塞器实施投放、打捞的专用工具，是堵塞器更换水嘴必不可少的工具。在投捞器下放过程中，投捞爪能否下放到位，投捞爪能否张开到位是影响投捞器投捞成功率的关键因素。本课题对投捞器投捞爪和凸轮控制装置进行改进设计，在投堵塞器的下入过程中，要确保投捞爪以及堵塞器完全收入投捞器的腔体内，不超过投捞器本身的最大直径，取消了投捞接头处的扭簧结构，提高了投捞的可靠性。对凸轮的外轮廓线进行改进，使得当凸轮转过一定角度后，投捞爪就能被释放，凸轮在下入过程中也要收入投捞器的最大直径内，上提时凸轮顺时针转动，释放投捞爪，导向爪的释放装置与投捞爪处的释放装置相似。把导向和投捞分工化，比传统投捞器导向和投捞都由投捞爪来完成更可靠，提高投捞的合格率。
