The invention discloses an LNG double-hose lifting device with a damping function and a hose lifting method.The LNG double-hose lifting device comprises two adjustable protection support assemblies, a lifting damping assembly and four supporting assemblies, transverse hydraulic damping assemblies are arranged between U-shaped bolts which are located at the same end and arranged on the peripheries of different arc-shaped protection supports in a sleeving mode, and when two hoses are lifted, the U-shaped bolts are arranged on the periphery of the arc-shaped protection supports in a sleeving mode; the hoisting shock-absorbing assembly is arranged on the hoisting shock-absorbing assembly, so that collision of the two hoses can be avoided, damage during hoisting is reduced, the hoisting shock-absorbing assembly is provided with the longitudinal hydraulic shock-absorbing assembly, impact of inertia on the hoses can be reduced, it is guaranteed that the bending radius of the two LNG low-temperature hoses in the whole hoisting operation process is larger than the minimum bending radius, and breakage of the hoses is avoided.

    本发明公开了一种带有减震功能的LNG双软管起吊装置及软管起吊方法,该装置包括两个可调式护托组件、起吊减震组件及4个支撑组件,位于同一端且套设于不同弧形护托外围的U型螺栓之间设有横向液压减震组件,在起吊两根软管的同时,能够避免两根软管的碰撞,减少了吊装时的损伤,起吊减震组件上设有纵向液压减震组件,能够对惯性作用对软管的冲击,保证了两根LNG低温软管在吊装作业全过程的弯曲半径大于最小弯曲半径,避免了软管的折损。
