The invention relates to a flexible lifting appliance for a vertical pipeline. The flexible lifting appliance comprises a lifting frame, a locking ring and a steel wire rope, wherein the lifting frame is of an arc-shaped structure; the two locking rings are fixed to the two ends of the lifting frame respectively, eccentric holes are formed in the locking rings, and the eccentric holes are located in the sides, close to each other, of the two locking rings; the steel wire rope penetrates through the two eccentric holes and is used for being hung on the hook. According to the flexible lifting appliance for the vertical pipeline, the similar circular ring defined by the lifting frame and the steel wire rope is arranged on the vertically-arranged pipeline in a sleeving mode, the steel wire rope is connected to a hoisting machine in a hung mode through the eccentric hole, when the flexible lifting appliance is used, the hoisting machine acts on the steel wire rope, the steel wire rope is stressed and shrunk, pressure on the pipeline is formed, the pipeline is attached to the lifting frame, and then friction force is generated; the pipeline lifting device is easy to operate and high in efficiency and safety during lifting operation.
本申请涉及一种竖直管道柔性吊具,包括吊装架、锁紧环以及钢丝绳;其中吊装架呈弧形结构设置;锁紧环,具有两个,分别固定在吊装架的两端,其上开设有偏心孔,所述偏心孔位于两锁紧环相近的一侧;钢丝绳穿过两个偏心孔,用于挂接在挂钩上。上述竖直管道柔性吊具,将吊装架和钢丝绳围成的类圆环套设在竖直放置的管道上,钢丝绳通过偏心孔挂接在起重机械上,在使用时,起重机械对钢丝绳作用,钢丝绳受力缩紧,并形成对管道的压力,使管道贴合在吊装架上,进而产生摩擦力,带动管道上升,操作简单,在吊装作业时效率及安全性高。
