RN254型铁钻工冲扣钳设计与力学分析
Design and mechanical analysis of RN254 roughneck shackle pliers
摘要
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.关键词
