The invention discloses a steel catenary stand pipe limiting device. The device comprises an anti-sinking assembly, a guide groove, a stand pipe terminal assembly and a limiting check block, wherein the guide groove is formed in the anti-sinking assembly; the vertical pipe terminal assembly comprises a supporting frame, sliding ways arranged on the two opposite sides of the supporting frame, an anchoring part arranged on the supporting frame, a pipeline connected with the anchoring part, a rotating arm rotationally arranged on the supporting frame, a connector connected with the rotating arm and an anode arranged at an end of the supporting frame, the supporting frame is arranged in the guide grooves in a sliding mode through the sliding ways on the two opposite sides; and the limiting stop block is arranged at the position close to a first end of the guide groove. The steel catenary riser limiting device can bear the dynamic tensile cyclic load of the riser, dynamic and static conversion is achieved, applicability of the steel catenary riser limiting device can be improved, the workload of underwater construction is reduced, and installation difficulty and the construction risk are reduced.

    本发明公开了一种钢悬链线立管限位装置,包括防沉组件、导向槽、立管终端组件以及限位挡块;所述导向槽设置在所述防沉组件上;所述立管终端组件包括支撑架、设置在所述支撑架相对两侧的滑道、设置在所述支撑架上的锚固件、与所述锚固件连接的管线、可转动设置在所述支撑架上的旋转臂、与所述旋转臂连接的连接器、以及设置在所述支撑架端部的阳极,所述支撑架通过相对两侧的所述滑道滑动设置在所述导向槽内;所述限位挡块设置在靠近所述导向槽第一端部的位置。本发明使得钢悬链线立管限位装置能承受住立管的动态拉伸循环荷载,实现动静转换,还能提高其适用性,减少水下施工的工作量,降低安装难度和施工风险。
