The invention relates to the field of self-elevating wind power installation ships, and discloses a large crane base around a pile leg and a machining process method. The large crane base comprises a crane base body and an internal reinforcing structure, and the crane base body reinforcing structure is located under a crane and over a deck. The base reinforcing structure is composed of a round-top square-bottom structure on the upper portion, a square frame structure on the lower portion, an internal T-shaped support of the square frame structure, related aggregates, toggle plates and the like. A pile leg of a wind power installation ship can vertically penetrate through the middle of the base, a large amount of deck space is saved, various loads generated when a crane jib works are effectively supported, stress concentration is relieved, the strength of the crane base and the strength of structures nearby the crane base are improved, and the yield strength and the buckling strength of the crane base are fully guaranteed.

    本发明涉及自升式风电安装船领域,公开一种绕桩腿的大型起重机基座及加工工艺方法包括起重机基座及内部加强结构,起重机基座加强结构位于起重机正下方,甲板正上方,基座加强结构由上部的天圆地方结构、下部的方形框架结构及其内部T型支撑、相关骨材、肘板等组成。本发明能够让风电安装船的桩腿从基座中间垂直穿过,节省了大量的甲板空间,有效地支撑起重机吊臂在工作时产生的各种载荷,缓解了应力集中,提高起重机基座及其附近结构的强度,充分保证起重机基座的屈服和屈曲强度。
