摘要：HXJ135DB海洋修井机在正常作业工况下，无法达到额定钩载能力的要求，给交流变频电机的正常使用和修井作业带来了一定的隐患风险。通过对修井机装机功率、绞车输入功率、传动比及传动效率等几个方面进行分析，提出了改变绞车传动比的改造设计。现场改造应用结果表明，本次改造设计虽降低了绞车的提升速率，但满足了提升能力的要求，设备运行可靠，满足了作业要求。

Abstract：Under normal operating conditions, The HXJ135DB offshore work over rig can not meet the rated hook load capacity, which brings risks for the normal operation of ac frequency converter motor and the operation of work over. Through the analysis of the installed power, draw work input power, transmission ratio and transmission efficiency and so on, proposed to the transformation mode of the increase transmission ratio of the draw work. Through the results of the application, the modified design has reduced the hoisting speed of draw work, but it has satisfied the requirement of lifting capacity, the equipment is reliable and satisfied the operation requirement.
Key words：offshore workover rig；AC variable-frequency motor；draw work；rated hook load
