The invention relates to an adjustable lifting and clamping device for an offshore oil pipe. The adjustable lifting and clamping device comprises two adjustable lifting and clamping units which are oppositely arranged. Each adjustable lifting and clamping unit comprises a lifting device, a rotary holding and clamping device and an auxiliary supporting device; the rotary clamping device comprises a first support, a second support, a first semi-ring block, a second semi-ring block, a first semi-gear ring, a second semi-gear ring, a plurality of clamps and a driving mechanism. The first support and the second support are slidably arranged on the top of the lifting device in the X direction. The change of the pitch angle of the oil pipe is controlled through the height difference of the two lifting devices, and the two lifting devices can horizontally move to adjust the distance so as to adapt to oil pipes of different specifications and sizes; and through the arrangement of the rotary clamping device, the oil pipe can be fixed, and the rotation angle can be controlled at the same time, so that the oil pipe can be flexibly adjusted in all directions, and the efficiency of butt joint, maintenance and debugging of the oil pipe is improved.

    本发明涉及一种海上油管可调举升夹持装置。其包括两个相对设置的可调举升夹持单元;每个可调举升夹持单元均包括举升装置、旋转抱夹装置以及辅助支撑装置;其中,旋转抱夹装置包括第一支架、第二支架、第一半环块、第二半环块、第一半齿圈、第二半齿圈、多个夹具以及驱动机构;第一支架、第二支架均其沿X方向滑动设置在举升装置的顶部。本发明通过两个举升装置的高度差来控制油管的俯仰角变换,并且两个举升装置能够平移调整间距,以适配不同规格尺寸的油管;还通过旋转抱夹装置的设置能够同时实现对油管的固定和旋转角度控制,从而使得油管能够向各个方向进行灵活调节,提高了油管对接、维修和调试的效率。
