The invention relates to the technical field of offshore drilling platforms, in particular to a lifting transmission device of an offshore drilling platform, which comprises a shell, a motor and a climbing gear shaft, a first-stage large gear used for driving the climbing gear shaft to rotate is arranged on the climbing gear shaft, and the first-stage large gear is meshed with the first-stage shaft gear. The device is suitable for a self-elevating drilling platform and a wind power installation platform, and the climbing gear is meshed with the pile leg rack, so that the pile leg can be lifted or lowered; lifting/lowering the platform at a rated lifting weight and a pre-ballasting state; and the weight of the platform is kept in a static state and a storm state.
本申请涉及海上钻井平台的技术领域,尤其是涉及一种海上钻井平台的升降传动装置,包括壳体、设置于壳体上的电机和爬升齿轮轴,所述电机的输出轴上设置有Ⅰ级轴齿轮,所述爬升齿轮轴上设置有用于带动爬升齿轮轴转动的Ⅰ级大齿轮,所述Ⅰ级大齿轮与Ⅰ级轴齿轮相啮合。本申请适用于自升式钻井平台和风电安装平台,通过爬升齿轮与桩腿齿条啮合,具有能够实现桩腿的提升/降低;在额定提升重量和预压载状态提升/降低平台;在静态保持和风暴状态保持平台重量的效果。
