自升式钻井平台升降系统在进行升降作业时,需对升降装置的核心部件——提升齿轮箱的末级齿轮承载转矩进行监测。利用该齿轮轴本体作为转矩测量的敏感元件,在其内部安装扭变传递组件及传感器,配置相应的测量电路,组成了对齿轮承载转矩进行测量的监测装置,并通过专用的加载设备对其进行加载标定试验,获得了较为理想的试验数据。 During the ascent and descent operation of a jack-up rig’s jacking system, it is necessary to monitor the carrying torque of the final gear of the lifting gear, which is the core component of the lifting device. The gear shaft body is used as a sensitive component of torque measurement, a torsion transmission component and a sensor are arranged in the gear shaft, a corresponding measuring circuit is arranged, and a monitoring device for measuring the torque of the gear is formed, and a special loading device pair It carries out loading calibration test and obtains the ideal experimental data.
