The invention provides a shipborne offshore helicopter lifting stabilizing platform. The platform comprises a movable platform, a base and a hydraulic telescopic assembly for connecting the movable platform and the base, and is characterized in that a plurality of horizontal, vertical and oblique spherical hinge sleeves are respectively arranged on the movable platform and the base, and the spherical hinge sleeves on the movable platform and the spherical hinge sleeves on the base are arranged in pairs. The hydraulic telescopic assembly at least comprises seven hydraulic cylinders, top balls are arranged at the hydraulic rod ends of the hydraulic cylinders, and bottom balls are arranged at the bottom ends of hydraulic cylinder bodies. The top ball and the bottom ball are respectively hinged with spherical hinge sleeves which are arranged on the movable platform and the base in pairs to form a ball pair, and the hydraulic rod and the hydraulic cylinder body form a kinematic pair. The movable platform can move in six directions in space. Under the condition that the structure of an existing helicopter stabilized platform is not greatly changed and original advantages of the helicopter stabilized platform are guaranteed, multi-dimensional motion of the workboat is effectively compensated, platform stability is guaranteed, the helicopter can safely ascend and descend, and safe operation of the workboat is guaranteed.
本发明提供一种船载海上直升机升降稳定平台,包括动平台、基座及连接所述动平台与基座的液压伸缩组件,其特点是:在动平台和基座上各设置若干个水平向、垂直向以及斜向的球铰套,且动平台上的球铰套与基座上的所述球铰套成对设置。液压伸缩组件至少包括7个液压缸,在液压缸的液压杆端设置有顶球,在液压缸体的底端设置有底球。所述顶球和底球分别与动平台和基座成对设置的球铰套铰接,并构成球副,液压杆与液压缸体构成运动副。使动平台实现空间六个方向的运动。本发明在未太大改动现有直升机稳定平台结构并保证其原有优势的情况下,有效补偿作业船所发生的多维度运动,保证平台稳定,使直升机安全升降,保证作业船安全作业。
