Description

Quick connecting device for offshore steel structure frame Technical Field The invention relates to the technical field of ocean engineering, in particular to a quick connecting device for an offshore steel structure frame. Background In many engineering fields, especially in situations involving underwater operations or where there is a certain requirement for the connection of components, the connection between components is a vital link. At present, two common connection modes of components are mainly adopted. The fixing connection is carried out through the bolts, the bolts penetrate through holes formed in the parts in advance and are screwed together with the nuts, and the parts are tightly attached together by means of pretightening force generated by threaded fit between the bolts and the nuts, so that connection is achieved. The other is a welding mode, and the metal materials of the connecting parts are melted and fused together through high temperature to form a firm connecting structure, so that the welding structure is widely applied to occasions with high requirements on the connecting strength. However, these two existing connection methods have obvious disadvantages. The bolt fixing connection operation is troublesome, in the installation process, the bolt holes on the components need to be accurately aligned, the smooth installation is difficult to be carried out with a little deviation, and a great deal of time and labor are consumed for screwing the bolts one by one. In the later maintenance or disassembly, the disassembly is difficult and even the parts are damaged due to the problems of rust, corrosion and the like of the bolts. However, the welding mode has high connection strength, but the welding is difficult to implement in an underwater environment. When underwater welding, the cooling effect of water can lead the welding seam to be quickly solidified, so that welding defects such as air holes, cracks and the like are easy to generate, and meanwhile, the factors such as low underwater visibility, limited operation space and the like also increase the difficulty and risk of welding operation, and the technical level and equipment requirements of welding personnel are extremely high.
