The invention discloses a hydraulic rotary tubing tong suspension arm for an ocean hydraulic workover rig, which consists of a stand column I, a pin shaft, a stand column II, a single-row tapered roller bearing, a rotary cylinder, a bearing pressing cap, a lock washer, a round nut, a swing hydraulic cylinder, a rotary cover, a limiting sleeve, a sliding hoisting trolley, a suspension arm assembly, a pipe clamp and a foot bar, and is used for hoisting tubing tongs and adjusting the position of the tubing tongs. The lifting arm of the oil pipe tongs is provided with the hydraulic rotating cylinder, the lifting arm can be controlled to rotate through hydraulic force, the sliding lifting trolley used for lifting the oil pipe tongs is provided with the boosting hydraulic cylinder, sliding can be controlled through hydraulic force, and manual operation is not needed. The operation range of the rotatable suspension arm assembly is 180 degrees, and the requirements that the oil pipe tongs are hoisted to the center of a wellhead during operation and rotated to the position where operation of operators is not affected when the oil pipe tongs do not need to be used are met. Compared with a conventional oil pipe tong suspension arm, the oil pipe tong suspension arm is high in bearing capacity, good in rigidity, large in moving range, convenient to overall disassemble and assemble, high in operation efficiency, low in labor intensity and good in safety.

    本发明公开了海洋液压修井机用液动旋转油管钳吊臂,采用立柱Ⅰ、销轴、立柱Ⅱ、单列圆锥滚子轴承、旋转筒、轴承压帽、止动垫圈、圆螺母、摆动液压缸、旋转盖、限位套、滑动吊装小车、吊臂总成、管夹、踏杆组成,用于吊装油管钳并对其进行位置调整。该油管钳吊臂配有液动旋转缸,可通过液压力控制吊臂旋转,用于吊装油管钳的滑动吊装小车配有助推液压缸,可通过液压力控制滑动,无需人力操作。可旋转的吊臂总成作业范围为180°,满足油管钳作业时将其吊装至井口中心,以及不需要使用油管钳时将其旋转至不影响操作人员作业处。与常规油管钳吊臂相比,本发明承载能力强,刚性好,活动范围大,整体拆装方便,作业效率高、劳动强度低、安全性好。
