Abstract

The invention relates to one sectional hoisting technique, which may be applied to series disperses freighter with 17.5 or 177000 tons, this hoisting technique includes: The district embarkation hoisting technique and the body section embarks the hoisting technique, respectively partitions the hoisting technique carries out the following step: a) determines the partition the actual tonnage; b) hanging establishment and hanging rigging equipment, which includes the selection steel wire's diameter, length, quantity, docking way and unloading gram, the load bearing tonnage and the material with which the suspenders corresponds; c) selects and arranges three gantry cranes hook; d) partitions stands up from failure the total group and the embarkation; e) controls partitions the time which the total group and the embarkation need. This invention partition hoisting technique, the host hung row of small, the hoisting working procedure are few, which causes the hull hoisting process and the tool utilization and the manpower arrangement which obtains the optimization, partitioned one time of arrive rate is high, the error was quite small, 100% guaranteed the hoisting success ratio.

Description

technical field

[0001] The invention relates to a segmental hoisting process, in particular to a segmental hoisting process of a whole ship. Background technique

[0002] At present, the existing implementation schemes for the typical segmental turnover construction and overall segmental hoisting process of the gantry cranes built in modern docks are as follows: 600-ton gantry cranes are used for individual turnover and platform assembly during segmental hoisting. The disadvantages are: front and rear assembly A 600-ton gantry crane needs to be used three times for assembly and loading; after turning over in sections, because the top is heavy and the bottom is light, it is necessary to use straight braces to support and position the outer panels during the general assembly of the platform to prevent tipping, which is time-consuming and laborious.

[0003] When hoisting the superstructure, two hooks of the upper trolley are used for hoisting, and t...
