摘　　要：针对斜直井齿轮齿条钻机特殊的管柱上/卸扣作业要求,提出了一种轨道钳作业装置和该装置的液压控制单元。基于键合图理论建立了轨道钳主、背钳夹紧系统和主钳转矩系统的键合图模型,并推导出了每个键合图模型的系统状态方程。基于20-Sim软件建立了轨道钳系统的键合图仿真模型,完成了对轨道钳系统的动态仿真,分析了系统动态特性产生的原因,验证了所建立的轨道钳系统的合理性。研究结果可为轨道钳系统装置的研制提供技术支持和理论指导。A track clamp system and the hydraulic control circuit are proposed for the special makeup and breakout operational requirements of the slant well gear rack drilling rig. The bond graph models of the main track clamp system,the back clamp tight system and the main tong torque system are established based on bond graph theory, and system state equations of bond graph model are deduced. Based on 20-sire software,the bond graph simulation models of rail clamp system are established and the dynamic simulations are carried out,the causes and effects of the system dynamic characteristics are analyzed,and the rationality of the track clamp system is validated. The result of study can provide technical support and theoretical guidance for development of track clamp system.
