摘要: 浮式钻井平台在深水作业过程中,液压驱动式天车升沉补偿装置由于技术成熟而得到广泛应用。针对液压驱动系统存在反应滞后性较大,补偿精度不高的缺点,提出了一种以主动齿轮-从动齿轮-直齿条轨道作为天车补偿驱动传递机构,以驱动电机作为补偿动力来源的机械驱动式天车升沉补偿装置,以提高天车升沉补偿的精度和效率。在对补偿装置机械驱动工作原理分析基础上,提出机械驱动式天车补偿装置的具体结构形式,并对主动齿轮与从动齿轮在传动过程中的受力情况进行分析,得到两齿轮在升沉补偿运动过程中的载荷分布。采用动力学分析方法对从动齿轮和直齿条轨道的传动过程进行分析,建立齿轮-齿条啮合过程动力振动分析模型,得到该过程的力矩平衡方程。采用该机械驱动结构会对直齿条轨道产生一定的振动激励。

Abstract: Hydraulic driven crown-block heave compensation device is widely used due to the mature technology on floating drilling platform in the process of deep-water operation. However, the hydraulic driven system is characteristic of delayed reaction and low compensation accuracy. This paper proposes a mechanical driven crown-block heave compensation device which has a driving gear-driven gear-straight rack rail as the compensation driving force transmission mechanism and a driving motor as the power source of compensation, to improve the accuracy and efficiency of the crown-block heave compensation device. Based on the analysis of the working principle of the device we put forward the concrete structure of mechanical driven compensation device, carried out stress analysis of the driving gear and driven gear in the process of transmission, and get the load distribution of two gears in the process of heave compensation movement. By adopting the dynamic method, we analyze the driven gear and straight rack rail in the transmission process, and establish the dynamic vibration analysis model of the gear and rack in the meshing process and get the torque balance equation, and we find out that the mechanical driven structure produces certain vibration excitation to the straight rack rail.

Key words: heave compensation, mechanical drive, rack and pinion, crown-block, drilling platform
