Pile leg pitch of self-elevating drilling platform
The invention discloses a pile leg pitch of a self-elevating drilling platform. The pile leg pitch is of a truss structure, wherein the truss structure is defined by three rectangular side faces, and the outer edge of the cross section of the truss structure is in an equilateral triangle shape. The pile leg pitch comprises landing leg chord members, main diagonal bars, auxiliary diagonal bars and inner stay bars. The three landing leg chord members are arranged at the vertexes of the equilateral triangle respectively. Each rectangular side face of the pile leg pitch comprises one main diagonal bar and one auxiliary diagonal bar located on the diagonals of the rectangular side face respectively. The two ends of each main diagonal bar and the two ends of the corresponding auxiliary diagonal bar are welded to two adjacent landing leg chord members respectively. Compared with the prior art, the number of pipes used for the pile leg pitch of an X-shaped structure is smaller, and the material cost is lowered; the number of pipe joints of the pile leg pitch is smaller correspondingly, and the welding work amount is greatly reduced; and meanwhile the stability of the pile leg pitch is better than that in the prior art due to lower borne wind loads and lower wave loads.
