However, the present invention should be understood not to be limited to the embodiments described below, and the technical idea of the present invention may be implemented in combination with other known techniques or other techniques having the same functions as the known techniques.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other suitable relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The transportable steel structure frame is generally made of channel steel and round steel, is of an I-shaped, single-column and # -shaped fixed structure, and is externally attached with an iron sheet or a fiberboard to form a prefabricated closed module. The closed module is transported integrally, and can accommodate air separation unit equipment such as a rectifying tower, a low-temperature pipeline, instruments and the like, wherein the tower is fixedly connected with the steel structure frame. The transportable steel structural frame is generally of a rectangular parallelepiped structure, and is usually transported with its longitudinal axis parallel to the ground, i.e. horizontally. At this time, the steel structure frame is also a horizontal low-temperature pipeline, especially a high-self-weight low-temperature pipeline can be elastically bent and deformed under the action of gravity, and in order to support the self-weight load of the pipeline and restrain the vertical displacement of the pipeline in the transportation process, a supporting structure with an upper end surface flush with the pipeline needs to be laid on the lower end surface of the pipeline, and the supporting structure comprises a supporting plate with at least one supporting surface parallel to the ground in the transportation process.
