Description

活页式捞筒
技术领域
本实用新型涉及一种打捞工具,特别是涉及一种活页式捞筒。
背景技术
活页式捞筒专门用来在大的环形空间里打捞鱼顶为带台肩或按箍的小直径杆类落物,如完整的抽油杆、带台肩和带凸缘的进下仪器等。目前采用的工具结构不合理,操作不方便,从而增加了打捞作业难度。
发明内容
本实用新型克服了现有技术中的不足,提供了一种结构筒单,操作方便的活页式捞筒。
为了解决上述问题,本实用新型采用以下技术方案:
活页式捞筒,包括上接头、活页总成和筒体,上接头上部为钻杆扣,上接头通过钻杆扣与钻柱连接,上接头下部呈筒形并设有内螺纹,上接头与筒体采用螺纹相接,筒体的上端面上安装着活页总成。
与现有技术相比,本实用新型的有益效果是:
本实用新型结构设计合理,操作方便,从而降低了劳动强度,提高了工作效率。
附图说明
图1为本实用新型结构示意图。
具体实施方式
活页式捞筒,如图1所示,包括上接头1、活页总成2和筒体3,上接头1上部为钻杆扣,上接头1通过钻杆扣与钻柱连接,上接头1下部呈筒形并设有内螺纹,上接头1与筒体3采用螺纹相接,筒体3的上端面上安装着活页总成2。
活页总成2由活页座、活页卡板、扭力弹簧和销轴组成。活页座焊在筒体3上端面,与活页卡板上的凸缘插装在一起,一个销轴从活页座和活页卡板上的小孔穿过。活页卡板被扭力弹簧压在筒体3上端面。活页卡板除凸缘外,中间还开一个宽度稍大于落鱼接箍下端管柱直径的长形口。筒体3的下端为锥形喇叭口,便于引进落鱼。
鱼顶为接箍的落鱼引入筒体3后,顶开活页卡板,活页卡板绕销轴转动。当接箍通过卡板后,在扭力弹簧的作用下卡板自动复位,接箍以下管柱正好进入活页卡板的开口里。上提工具,接箍卡在活页卡板上,完成打捞作业。
