在钻孔施工中，利用吊锤起拔套管及处理孔内事故钻具，是一项繁重的体力劳动，实现吊锤机械化则是广大钻探职工的长期愿望。在毛主席的革命路线指引下，我局地质六队广大职工，在队党委的正确领导下，从一九七四年开始，首先参照“钻探技术手册”设计了“差速式吊锤机”，随后在水电部“弹簧起管锤”的启示下，经过对比，认为“弹簧吊锤”较“差速式吊锤”简便、易行，便于一九七四年年底开始了“弹簧吊锤”的设计、试制、实验工作，两年来共进行了三次设计、四次试制、改进和
In the drilling process, lifting the casing with a peening hammer and handling the drill in the hole is a heavy manual work. The realization of mechanization of the peening hammer is the long-term desire of the majority of drilling workers. Under the guidance of Chairman Mao’s revolutionary route, under the correct leadership of the team’s party committee, the majority of the staff of the Geological Sixth Division of the Bureau began work in 1974 with reference to the “Drilling Technical Manual” to design a “differential speed crane”. Then, in the enlightenment of the Ministry of Water and Electricity “Spring-loaded pipe hammer,” after comparison, it was considered that the “spring-hammer” was simpler and easier than the “differential-speed-hanging hammer” and it was easy to start the “spring hammer” at the end of 1974. The design, trial production, and experimental work of the company have carried out three designs, four trial productions, improvements, and
