An installation method of a semi-submersible type hoisting and disassembling platform crane comprises the following steps that firstly, a suspension arm (2) in the crane (4) is installed on a samson post (1) at a wharf, and the suspension arm (2) is installed on the samson post (1) through a bearing; secondly, the crane (4) is transported to a floating crane berthing position, and the fixation ofthe crane (4) and a transport ship is relieved; thirdly, hoisting points A and C are arranged at the bottom of the samson post (1) of the crane (4), and strain gauge type force sensors are arranged atthe hoisting points A and C; hoisting points B and D are arranged on the middle portion of the suspension arm (2); fourthly, a floating crane hoisting rope is prepared according to requirements and is connected with a rigging; the rigging is connected to a hoisting point of a hoisted object according to the arrangement position of the rigging, and the rigging is naturally tightened; fifthly, hoisting is conducted at a constant speed till the hoisted object is separated from a base; the resultant force of the acting force of a hoisting hook is over the gravity center of the crane (4); and sixthly, the floating crane hoisting rope is adjusted to erect the hoisted object to the installation state, the hoisted object is shifted to the installation ship position, and then the crane is loweredonto the base (3). By means of the installation method, a large number of field construction correction workloads are reduced, and the product quality is improved.
一种半潜式起重拆解平台吊机安装方法,包括以下步骤:一:在码头将吊机(4)中的吊臂(2)安装在将军柱(1)上,吊臂(2)通过轴承安装到将军柱(1)上;二:将吊机(4)运输至浮吊停泊位置,拆除吊机(4)与运输船的固定;三:吊机(4)的将军柱(1)底部设A、C吊点,在A、C吊点处设应变片式力传感器;在吊臂(2)中部设B、D吊点;四:按要求准备浮吊吊绳,并连接索具;按照索具布置的位置,将索具连接到被吊物吊点上,并自然收紧;五:匀速起吊至被吊物脱离底座;起吊钩作用力的合力在吊机(4)重心正上方;六:调整浮吊吊绳将被吊物立正到安装状态,移泊至安装船位,然后将吊机下放至基座(3)上。本发明减少大量的现场施工修正的工作量,提高了产品的质量。
