Special superstructure general assembly lifting lug structure

Abstract

The invention relates to a special superstructure general assembly lifting lug structure which comprises a superstructure body, bulkheads and lifting lugs, the superstructure body comprises a plurality of bulkheads, the lifting lugs are fixed to the tops of the bulkheads in a segmented mode, the superstructure body can be directly lifted through matching of the lifting lugs and steel wire ropes, and the overall lifting strength of a superstructure is guaranteed; the installation method comprises the steps that 1, on the premise that the overall hoisting strength of the superstructure is guaranteed, a lifting lug style is planned; 2, the top structure of the bulkhead is modified, and a lifting lug mounting groove is reserved and changed into a form capable of being used for lifting; 3, thelifting lugs are installed and fixed, the lifting safety is guaranteed, a lifting scheme is considered in the superstructure segmented drawing design stage, part of the bulkhead top structure is modified, the structure is directly made into a continuous lifting ring and permanently reserved, the stability and structural strength of the lifting lugs are enhanced through toggle plates, the subsequent lifting lug installation work is reduced, and the construction period is shortened. Under the condition of guaranteeing the hoisting safety, the simple steel wire rope configuration is used for hoisting, the construction amount is reduced, and the hoisting risk is reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding dock structures, in particular to a special superstructure assembly lifting lug structure. Background technique [0002] With the improvement of the capacity of gantry cranes in modern shipbuilding and dock work, the construction period has been greatly shortened. Many on-site works are carried out in separate lanes and started at the same time. For example, superstructure fabrication and main hull are constructed separately. The overall hoisting of the superstructure is of great significance to shorten the shipbuilding cycle, reduce labor costs and improve production efficiency. The superstructure is large in size, heavy in weight and relatively weak in rigidity, so the lifting lugs of the superstructure are specially designed to ensure smooth hoisting. [0003] Conventional lifting lugs are relatively standardized, but because the superstructure plates are relatively thin, the overall rigidity is we...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a special lifting lug structure for the general assembly of the superstructure, which solves the problem that due to the thinness of the superstructure boards, a large number of lifting lugs need to be provided during the hoisting process, the construction volume is large, and the steel wire rope is damaged during the lifting process. It is difficult to match and there is a problem of lifting risk
