Embodiment Construction

[0020] Such as Figure 1 to Figure 3 A special superstructure assembly lifting lug structure is shown, including superstructure body, bulkhead 1 and lifting lug 2, the superstructure body includes several bulkheads 1, and the lifting lug 2 is fixed on the bulkhead in sections 1 the top, the upper body can be hoisted directly through the matching steel wire rope of the lifting lug 2, so as to ensure the strength of the overall hoisting of the upper building.

[0021] The lifting lug 2 includes a first lug 21 , a second lug 22 , a third lug 23 and a fourth lug 24 reinforced by brackets to enhance the stability and structural strength of the lug.

[0022] The first lifting lug is a first fixing surface and a first lifting joint surface vertically connected to each other to form a right-angled triangle structure, and a plurality of first lifting holes are opened on the first lifting joint surface, and between adjacent lifting holes The spacing is equal, and the first lifting lug ...

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...
