[0022] The platform is an elevated three-dimensional frame, and the frame is an angle steel connection structure. The top of the column angle steel 10 is welded to the platform angle steel 8, and the ends of the platform angle steel 8 and the ends of the column angle steel 10 are welded and fixed to the cabin wall and the cabin deck through pads. This application will make the platform components where the corresponding pipelines and equipment are tight into a detachable structure, cut the breakpoints at the platform components, and detachably connect them through connecting plates and bolts. Under the premise of ensuring the safety requirements for personnel climbing, the independent detachability of the platform can also be met to avoid the risk of fire and explosion caused by subsequent hot work on the platform.

[0023] like Figure 1 As shown, the connection structure of the detachable platform for maintenance of engine room pump room equipment includes a disconnected platform angle steel 8, a column angle steel 10 divided into two, a vertical connecting piece 1, a supporting connecting piece 2, a connecting piece 3, a web connecting piece 4 and a horizontal connecting piece 5.
