The invention relates to a tool for hoisting a workpiece with an annular groove in an inner hole, which is used for locking, hoisting and releasing the workpiece positioned in a deep hole and comprises a hoisting rod, a lifting rod and a lifting rod, the top of the release sleeve is in threaded connection with the lower end of the lifting rod, a plurality of slope opening grooves are formed in the outer wall of the release sleeve, the slope opening grooves are evenly distributed in the circumferential direction of the release sleeve, and each slope opening groove extends in the length direction of the release sleeve; the separation sleeve is sleeved with the main body sleeve, a limiting step is arranged at the top of the main body sleeve, and the bottom of the limiting step abuts against the top of the separation sleeve; the ejection mechanisms are arranged in the sleeve wall of the main body sleeve and are arranged in the circumferential direction of the main body sleeve; when the ejection mechanisms are not ejected out, the multiple ejection mechanisms correspond to the slope opening grooves in a one-to-one mode. And when the lifting rod and the release sleeve rotate together, the ejection mechanism is gradually ejected out by the slope opening groove and is separated from the slope opening groove, and the ejection mechanism separated from the slope opening groove is locked with the workpiece.
本发明涉及一种吊装内孔带环形凹槽工件的工具,用于锁紧、起吊、以及释放位于深孔中的工件,包括:起吊杆;分离套筒,其顶部与起吊杆的下端螺纹连接,分离套筒的外壁上设置有若干个斜坡口槽,若干个斜坡口槽绕分离套筒周向且均匀布置,每个斜坡口槽沿分离套筒的长度方向延伸;主体套筒,套设在分离套筒外,主体套筒的顶部设置有限位台阶,限位台阶的底部与分离套筒的顶部相抵接;顶出机构,若干个顶出机构设置于主体套筒的筒壁内,且绕着主体套筒周向设置;在顶出机构未被顶出时,若干个顶出机构与斜坡口槽一一对应设置;在起吊杆连同分离套筒旋转时,顶出机构被斜坡口槽逐渐顶出并脱离斜坡口槽,脱离斜坡口槽的顶出机构与工件锁紧。
