The invention discloses a steering multi-equipment combined hoisting method for a large liquid tank of a gas ship. The hoisting process comprises the following specific steps: preparation work: preparing a slipway, an assembly site, a barge, a flat car, a gantry crane, a sling and a lifting hook; lifting hooks comprise a first lifting hook, a second lifting hook and a third lifting hook, the third lifting hook is hooked on the gantry crane and is connected with a cross supporting beam through a sling, and the first lifting hook and the second lifting hook are arranged on the cross supporting beam through slings; hoisting: hooking a first lifting hook and a second lifting hook on the tank body, horizontally hoisting the tank body to a flat car by a gantry crane, supporting the tank body by the flat car, loosening the first lifting hook and the second lifting hook, rotating and correcting the tank body, re-hooking the first lifting hook and the second lifting hook, integrally hoisting, and horizontally hoisting the tank body to a temporary storage position; in the whole hoisting process, the flat car assists steering of the liquid tank in the liquid tank hoisting process, application of tools of the first lifting hook, the second lifting hook and the third lifting hook is optimized, and safe and reliable operation of hoisting steering of the liquid tank is guaranteed.
本发明公开了一种气体船大型液罐转向多设备联合吊装方法,吊装工艺具体步骤包括:准备工作:准备船台、总组场地、驳船、平板车,龙门吊、吊索、吊钩准备;吊钩装配:吊钩采用第一吊钩、第二吊钩、第三吊钩,第三吊钩钩装于龙门吊上,第三吊钩通过吊索连接有横撑梁,横撑梁上通过吊索分别配置有第一吊钩、第二吊钩;吊装:第一吊钩、第二吊钩挂钩于罐体上,龙门吊将罐体平吊至平板车上且用平板车罐体承托,松开第一吊钩、第二吊钩,旋转转正罐体,第一吊钩、第二吊钩重新挂钩,整体起吊,将罐体平吊至临时存放处;整个吊装工艺在液罐吊装过程中通过平板车辅助液罐转向,优化第一吊钩、第二吊钩、第三吊钩的工具的运用,保证液罐吊装转向安全可靠的地运行。
