用于海洋钻机猫道上的套管辅助支撑架
摘要：
本发明公开了一种用于海洋钻机猫道上的套管辅助支撑架，采用幼儿滑梯式结构，由固定在猫道平直段支撑面上的平直支撑段和倾斜支撑段组成，所述平直支撑段距离猫道斜坡段较远，所述倾斜支撑段距离猫道斜坡段较近，在所述平直支撑段远离倾斜支撑段的端部设有端部限位挡板，所述平直支撑段的两侧和所述倾斜支撑段的两侧均设有侧向限位挡板。本发明利用平直支撑段来降低套管下端与上端的初始位置高差，利用倾斜支撑段逐渐加大套管下端与上端的高差，进而使套管平稳的上移，降低了作业风险；不用吊机辅助作业，占用吊机时间短，移运作业简便，并且降低了作业的劳动强度，提高了作业效率，能够节省下套管作业时间，提高钻井作业时效，节约作业成本和钻井成本。
摘要（英）：

The invention discloses a sleeve auxiliary support frame for a marine drilling rig catwalk. The sleeve auxiliary support frame is of a child slide structure, and is composed of a straight supporting section fixed on the supporting surface of the straight section of the catwalk and an inclined supporting section; the straight supporting section is far away from the slope section of the catwalk, while the inclined supporting section is close to the slope section of the catwalk; an end portion limiting baffle plate is arranged at the end portion, far away from the inclined supporting section, of the straight supporting section; lateral limiting baffle plates are arranged on the two sides of the straight supporting section and the two sides of the inclined supporting section. According to the sleeve auxiliary support frame, the initial position height difference of the lower end and the upper end of the sleeve can be reduced by use of the straight supporting section, and the height difference between the lower end and the upper end of the sleeve can be gradually increased by use of the inclined supporting section, and therefore, the sleeve can be moved upwards steadily and the operation risk is reduced; no crane is needed to assist the operation, the time of occupying the crane is short, the movement operation is simple and convenient, and the labor intensity of the operation is reduced and the operation efficiency is improved; the sleeve dropping operation time can be saved, the drilling operation efficiency can be improved, and the operation cost and the drilling cost can be saved.
