机械驱动式天车升沉补偿装置研究
Research on Mechanical Driven Crown-Block Heave Compensation Device
摘要
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.关键词
