The invention discloses a combined lifting appliance for a single-hook lifting and four-point lifting of an offshore booster station. The combined lifting appliance comprises a horizontal frame. The horizontal frame comprises two transverse rods, two longitudinal rods and four connecting assemblies, the two ends of each transverse rod are connected with the lower portion of the corresponding connecting assembly respectively, and the two ends of each longitudinal rod are connected with the lower portion of the corresponding connecting assembly respectively, so that when the horizontal frame is used for hoisting, the transverse rods are kept on the horizontal plane lower than the longitudinal rods, and the overall top view of the two transverse rods, the two longitudinal rods and the four connecting assemblies which are connected with each other is roughly rectangular. An included angle with a preset size is formed between the extending direction of each connecting assembly and a plane formed by the transverse rods and the longitudinal rods, and the intersection point of the extending directions of the four connecting assemblies is kept in the center of the horizontal frame which is approximately rectangular in the top view. By means of the technical scheme, it can be guaranteed that four lifting lugs are lifted by four vertical lifting pieces.

    本发明公开了一种用于单钩起吊四点吊载海上升压站组合吊具,其包括一水平架。所述水平架包括两横杆、两纵杆和四个连接组件,其中每个所述横杆的两端部分别与一个所述连接组件下部连接,每个所述纵杆的两端部分别与一个所述连接组件的下部连接,以在所述水平架被用以起吊时,所述横杆保持在低于所述纵杆的水平面,并使得相互连接的两所述横杆、两所述纵杆以及四个所述连接组件整体俯视图大致呈矩形。所述每个所述连接组件的延伸方向与所述横杆和所述纵杆形成的平面呈预定大小的夹角,且四个所述连接组件延伸方向的交点保持在俯视图大致呈矩形的所述水平架的中心。通过本发明的技术方案,能保证四个吊耳被四个呈竖直状的起吊件吊起。
