The invention discloses an integral hoisting method for folding hatch covers of a polar region multipurpose ship. The integral hoisting method comprises the following steps that a, two hatch covers are respectively hoisted and placed on a transportation bracket; b, the two hatch covers are transported to a general assembly site through a transport flat car; c, adjusting the positioning precision of the cabin cover; d, connecting pin shafts between the hatch covers are installed; e, installing a back folding preventing T-shaped tool; f, selecting a 400T gantry crane for hoisting; h, hatch cover lifting point positions are determined; i, determining a lifting point form; j, mounting a hoisting shackle and a steel wire rope; and k, hooking and integrally hoisting the slipway to fold. According to the integral hoisting method for the folding hatch cover of the polar region multi-purpose ship, the problem that a single folding hatch cover is hoisted for multiple times and the safety problem that the folding hatch cover is easily reversely folded during hoisting are solved, the hoisting and carrying efficiency is improved, the construction period is shortened, and the competitiveness is greatly improved.

    本发明公开了一种极地多用途船折叠式舱盖整体吊装方法,包括以下步骤:a,两片舱盖分别吊装放置运输托架;b,使用运输平板车将两片舱盖运输总组场地;c,调整舱盖定位精度;d,安装舱盖之间连接销轴;e,安装防背折T型工装;f,选定400T龙门吊车吊装;h,确定舱盖吊点位置;i,确定吊点形式;j,安装吊装卸扣及钢丝绳;k,起钩整体吊装船台合拢。本发明极地多用途船折叠式舱盖整体吊装方法,解决了单个折叠舱盖多次吊装的问题和折叠式舱盖吊装容易出现反向折叠的安全问题,提高了吊装搭载效率,缩短工期,大大提高了竞争力。
