| 中文摘要:为了提高绳索取心钻进的技术水平，弥补普通绳索打捞器的缺陷，研制了SSD-96型绳索取心安全打捞输送器。该安全打捞输送器可以在地表通过控制钢丝绳绞车来改变打捞钩口的张开大小，从而完成安全打捞输送器从打捞状态向脱卡状态转换。文章介绍了安全打捞器的打捞原理和脱卡原理，以及打捞遇阻时和干孔或水位不足时输送内管到预定位置后安全脱卡的工作方法。该安全打捞输送器在河北省承德市张营矿区的野外应用试验中取得了良好的效果。 |

| Abstract:In order to improve the technical level of wire-line core drilling and remedy the defects of common wire-line overshot, SSD-96 type wire-line core overshot is developed, by which the opening of fishing hook can be adjusted through controlling the steel wire winch on the ground surface to complete the process from fishing to releasing. The paper introduces the principles of fishing and releasing with the safety releasing methods after conveying the inner tube to the predetermined position while encountering difficulties or dry hole and water shortage. This overshot has good effect in the field application test in Zhangying mining area of Chengde. |
