Truss type pile leg with descending buffer structure
The invention discloses a truss type pile leg with a descending buffering structure. The truss type pile leg comprises a truss, a main body sinking pad, a supporting plate, a gear shaft, a gear and asensor. When the self-elevating drilling platform is inserted in place, the descending state of the pile leg can be actively monitored, and the disadvantage that in the prior art, measures are passively taken is avoided. Whether the pile leg reaches a balance state or not can be judged according to data fed back by the displacement sensor, and if not, upward counter force can be continuously provided for the gear. Whether the gear can continuously bear the pressure from the pile leg or not can be judged according to the pressure sensor, if the pressure sensor displays that the pressure is close to the warning value, upward counterforce is stopped, and device damage is avoided. The main body sinking pad is arranged on a mud surface in use and used for dispersing and buffering external forceborne by the gear when the pile leg descends, and device damage is avoided. By means of the structure, pile legs sink slowly during pile pitching of the self-elevating drilling platform, and overturning of a ship body is avoided. Therefore, the large device is erected on a stable foundation, and the safety of offshore large facilities is guaranteed.
本发明公开了一种具有下降缓冲结构的桁架式桩腿，包括桁架、主体沉垫、支撑板、齿轮轴、齿轮和传感器；本装置在自升式钻井平台就位插桩时，可以主动监测桩腿下降状态，避免了现有技术中被动采取措施的劣势。根据位移传感器反馈的数据可以判断桩腿是否达到平衡状态，若未达到则可继续对齿轮提供向上反力；根据压力传感器可以判断齿轮能否继续承受来自桩腿的压力，若压力传感器显示接近警戒值，则停止提供向上反力，避免装置损坏。主体沉垫使用时置于泥面之上，用于分散缓冲桩腿下降时齿轮所受的外力，避免装置损坏。该结构实现了自升式钻井平台插桩时桩腿缓慢下沉，避免船体倾覆。使得大型装置立于稳定基础之上，保证了海上大型设施的安全。
