摘要
铁钻工作为安全、高效的钻杆拧卸工具,逐步取代了液气大钳,成为自动化钻探装备的标准配置.作为铁钻工核心部件的冲扣钳对于整个铁钻工的工作性能至关重要.通过分析冲扣钳的结构原理及工作方式,进行油缸选型与力学分析,为RN254型铁钻工设计了一套高效率的冲扣钳结构装置,并进行了野外生产试验.试验表明,冲扣钳结构设计科学,油缸选型合理,极大地提高了铁钻工的工作效率,为铁钻工的设计制造提供了借鉴.
Abstract
Roughneck is a safe and efficient tool for screwing and unscrewing drill pipes,gradually replacing hydraulic and pneumatic tongs and becoming a standard configuration for automated drilling equipment.As the core component of roughneck,the shackle pliers are crucial to the performance of the entire iron roughneck.By analyzing the structural principle and working method of the shackle pliers,we conducted an oil cylinder selection and mechanical analysis.This led to the design of a highly efficient shackle pliers structure for the RN254 roughneck,which was then tested in field production.The test shows that the scientific structure design of the shackle pliers and the reasonable selection of the oil cylinder greatly improve the work efficiency of the roughneck,providing a reference for the design and manufacturing of roughneck.
