扭叉是机械拧卸管的辅助工具.过去所用的扭叉,在回转离心力的作用下,常会飞离钻杆卡槽,对井口操作人员的安全有很大威胁.为了解决这个问题,探矿安全组同志深入机台,征求工人同志意见,设计试制了安全扭叉(如右图),经过反复实践,不断修改,这种扭叉已在机台应用并投入铸钢生产.此安全扭叉重量同原来的扭叉相近,操作也较方便.由于其开口的方向相反,所以 The torsion fork is an auxiliary tool for screwing the pipe. The torsion used in the past, under the action of the rotating centrifugal force, often flies away from the drill pipe slot, which poses a great threat to the safety of the wellhead operator. In order to solve this problem, the prospecting safety Comrades of the group went deep into the platform to solicit the opinions of the workers and comrades, designed and trial-produced the safety torsion (as shown on the right). After repeated practice and constant revision, this torsion fork was applied on the machine bed and put into the production of cast steel. This safety torsion weight Similar to the original twist fork, the operation is also more convenient. Because the direction of its opening is opposite, so
