Hanging bar without shackle connection

Abstract

The invention discloses a hanging bar without shackle connection, which comprises a supporting beam (1), a main stressed beam (2), an end seal plate (3) of a main beam, an enhanced ring plate (4) of an outside blocking rope, an enhanced ring plate (5) of an inside blocking rope, a semi-enhanced ring plate (6), an enhanced toggle plate (7), a seal plate (8) of a tubular lifting lug, a longitudinalupright plate (9) of the tubular lifting lug, a main beam (10) of the tubular lifting lug, a transverse upright plate (11) of the tubular lifting lug, an enhanced upright plate (12) of the main stressed beam (12) and conveying lifting lugs (13), wherein the conveying lifting lugs (13) are arranged on two sides of the supporting beam (1). The hanging bar without shackle connection is free of connection by large-size shackles; and the hanging module of the hanging bar is 25m in maximal width, can be manufactured according to different sizes of the module, and has the maximal carrying capacity of 900 tons; the design method provided by the invention greatly increases the contact area of a steel wire rope so that the steel wire rope can be favorably protected and the use efficiency of the steel wire rope can be improved.

Description

technical field [0001] The invention relates to the field of large-scale module hoisting engineering on the upper deck of a floating production, storage and unloading device vessel (FPSO) and other marine engineering products, in particular to a shackle-free connection hoisting bar ear. Background technique [0002] With the gradual discovery of the world's large deep-sea oil fields, the demand for FPSO ships in the international market has gradually increased, and the construction tonnage has become larger and larger from the original 100,000 tons to 300,000 tons and 400,000 tons. Functional modules on the deck of FPSO ships The tonnage has also increased to 500-2000 tons or even more. The module itself has a weak structure but is very expensive. Therefore, in order to ensure the safety of the module installation process, the use of large hanging bars is essential. When the wire rope is connected, it is completed by the shackle, which is very inconvenient to operate when t...

Problems solved by technology

[0002] As the world's large deep-sea oil fields are gradually discovered, the demand for FPSO ships in the international market is gradually increasing, and the construction tonnage is increasing from the original 100,000 tons to 300,000 tons and 400,000 tons. The functional modules on the FPSO ship deck The tonnage has also increased to 500-2000 tons or more. The structure of the module itself is weak but the value is very expensive. Therefore, in order to ensure the safety of the module installation process, the use of large suspension bars is essential. Now most large suspension bars are used in conjunction with The connection of steel wire ropes is completed by shackles, which is very inconvenient to operate when slings are assembled. In the past, 4-6 connecting shackles with a tonnage of 400 and 500 tons were generally used when lifting FPSO ship modules. Hanging bar connection, the original 900 hanging bar form see figure 1 , four 500-ton shackles are used at the connection position between the wire rope and the hanging bar. Because the weight of the shackles is relatively large, each shackle is about 0.8 tons, and the shape and size are relatively special. It is difficult for personnel to operate during assembly, and a lot of manpower and material resources are required. Cooperating, it is a great waste of data, and after use, the wire rope will have creases at the shackle connection position, which will reduce the service life of the wire rope, so a new type of suspension bar design without shackle connection is imperative
