摘要
以某自升式钻井平台为例,采用"电机+变速箱+小传动轮+齿条"方式驱动悬臂梁移动。通过悬臂梁的结构及悬臂梁上的设备质心确定移动悬臂梁所需的推力。计算悬臂梁齿轮齿条几何参数,并设计悬臂梁与齿轮齿条的连接结构及悬臂梁驱动控制系统,合理配置驱动系统电机功率和减速器传动比。通过采用闭环交流变频控制方式,对悬臂梁速度进行反馈和控制,实现左右两侧悬臂梁的同步移动。
It takes a self-elevating drilling platform as the sample to move the cantilever beam by the mode of ＂motor ＋ gearbox ＋ small drive wheel ＋ rack＂. The required push force to move the cantilever beam is determined by the cantilever structure and the centre of gravity of the installation weight on the cantilever. The geometric parameters of the gear rack of the cantilever beam should be calculated when designing the linkage structure between the cantilever beam and the gear rack and the driving control system of cantilever beam with the rational allocation of the motor power of the driving system and the transmission ratio of the speed reducer. A closed-loop AC frequency control mode is introduced to conduct feedback and control of the speed of the cantilever beam in an attempt to achieve synchronized movements at left and right sides of the cantilever beam.
