The invention discloses a mobile docking device for installing a wellhead blowout preventer group and a docking method thereof.The mobile docking device comprises two drilling machine hanger rails on which hoisting and moving devices are hung respectively, the two drilling machine hanger rails are fixed to the lower portion of a drilling platform in parallel, and docking hanger rails are arranged at the outer ends of the drilling machine hanger rails respectively; the butt-joint hanger rail is fixed below the drilling platform through a lifting lug; the two ends of the two butt-joint hanger rails are connected through a connecting cross beam, the middle sections of the two connecting cross beams are connected with vertical hangers, the lower ends of the two vertical hangers are connected with horizontal bearing seats, and the center lines of the horizontal bearing seats and the vertical hangers and the center line between the two drilling machine hanger rails are located in the same vertical plane; the width of the horizontal bearing seat is larger than the outer edges of the two butt-joint hanger rails in the width direction, and the top face of the horizontal bearing seat is flush with the bottom of the blowout preventer hoisting and moving device. Baffles are welded to the ends, away from the drilling machine hanger rail, of the two butt-joint hanger rails respectively. The device is convenient to install and transport, the installation time can be shortened, the labor intensity of workers is relieved, and the operation safety is improved.

    本发明公开了一种井口防喷器组安装用移动对接装置及其对接方法,包括各自悬挂有吊装移动装置的两钻机吊轨,两钻机吊轨相互平行固定于钻井平台的下方,钻机吊轨的外端头分别设有对接吊轨,对接吊轨通过吊耳固定在钻井平台下方;两对接吊轨的两端通过连接横梁相连,两连接横梁的中段连接有竖向吊架,两竖向吊架的下端连接有水平承托座,水平承托座及竖向吊架的中心线均与两钻机吊轨之间的中心线位于同一个竖直平面内;水平承托座的幅宽大于两对接吊轨宽度方向的外沿,水平承托座的顶面与防喷器吊装移动装置的底部平齐;两对接吊轨远离钻机吊轨的端头分别焊接有挡板。该装置安装运输方便,可以缩短了安装时间,减轻工人的劳动强度,提高作业安全性。
