      詳細說明

      自升式鉆井平臺液壓升降系統由一套獨立的液壓驅動系統提供動力,確保樁腿能夠克服泥土、砂石等帶來的阻力和升降平臺自身的重力,將樁腿插入(拔離)海床以及升降整個平臺。根據平臺升降工況、作業工況、自存工況、預壓工況的重量重心計算及環境載荷的計算結果,確定升降系統的正常升降能力、預壓升降能力、船體升降速度。

      結構及組成

      鉆井平臺液壓升降系統主要由主油缸、插拔銷機構、液壓站及控制系統、液壓軟管及接頭、安全裝置、行程檢測系統等組成。

      液壓升降系統的執行機構分別安裝在鉆井平臺的四個角上,每套執行機構由樁體、上環梁、插銷機構、主油缸、下環梁等組成。通過上、下兩組插銷機構交替伸縮(上環梁為動環梁,下環梁固定在平臺船體上),配合主油缸的伸縮,來實現整個樁腿的下樁、插樁、升平臺、調平、落平臺、拔樁、起樁動作。

      一套平臺升降系統共有多臺液壓泵,其中主泵向主油缸供油,油泵向電液比例換向閥供油,油泵為插銷油缸供油。根據升降平臺不同工況,當主油缸空載運動時,系統自動提高泵的流量,降低壓力從而提高系統的工作效率;當主油缸處于待載工作的時候,系統自動降低流量,提高壓力從而保障系統安全可靠的工作。這樣將大大降低系統的整體功率,節約能耗,提高工作效率。
