Adjustable support device for reverse installation of lifting lugs in building process of ship

Abstract

The invention discloses an adjustable support device for reverse installation of lifting lugs in the building process of a ship. The adjustable support device comprises a bottom plate arranged on the horizontal ground, wherein lifting columns are fixedly arranged above the bottom plate; a top plate for supporting the lifting lugs are arranged at the top ends of the lifting columns and is provided with lifting-lug placing holes of the lifting lugs; the peripheries of the lifting-lug placing holes are also provided with lifting-lug limiting pipes for preventing displacement of the lifting lugs; a supporting block welded at the lifting columns is arranged under the top plate; and at least one jack for jacking a support. The adjustable support device disclosed by the invention can be used for installation work of sectional and reverse lifting lugs of a ship body, is beneficial to guaranteeing the positioning quality of the lifting lugs and the installing and welding quality of the lifting lugs, can effectively reduce the stress generated by staggering when the reverse lifting lugs are installed, reduce the workload and the difficulty degree for installation of the reverse lifting lugs and can be widely applied to the building site of the ship.

Description

technical field [0001] The invention relates to a bracket, in particular to an adjustable bracket device used for reverse mounting lugs during shipbuilding. Background technique [0002] In the process of ship construction, the safety of segmental lifting has always been the focus of major shipyards, because it not only involves the safety of the staff and the interests of the shipyard, but also the key to the improvement of the production efficiency of the shipyard. However, in the past In the process of lifting the ship in sections, safety accidents caused by welding quality problems of lifting lugs still occur from time to time. Most shipyards use tire frames with a height of 60cm to 100cm when manufacturing in sections, and the lifting lugs on the reverse side of the sections are generally installed after the tires are installed in sections. Because the lifting lugs are large and heavy, workers mainly rely on cranes and lever to position and weld the lifting lugs. Due t...

[0002] In the process of ship construction, the safety of segmental lifting has always been the focus of major shipyards, because it not only involves the safety of the staff and the interests of the shipyard, but also the key to the improvement of the production efficiency of the shipyard. However, in the past In the process of lifting the ship in sections, safety accidents caused by welding quality problems of lifting lugs still occur from time to time

Most shipyards use tire frames with a height of 60cm to 100cm when manufacturing in sections, and the lifting lugs on the reverse side of the sections are generally installed after the tires are installed in sections. Because the lifting lugs are large and heavy, workers mainly rely on cranes and lever to position and weld the lifting lugs. Due to the small space and difficulty in welding the reverse lifting lugs, the stress concentration after the lifting lugs are installed, the welding quality is poor, and the safety is difficult to be effectively guaranteed. the danger of
