[0062] According to the spacing between the guide rail center lines of the respective guide rail segments drawn on the cabin top plate, draw the guide rail center lines correspondingly on each first connecting plate.

[0063] Adjust the rod body lengths of the suspension rods 6 of each first connecting plate extending from the upper surface of the first connecting plate 4 so that the extended rod body lengths are equal to the theoretical thickness of the guide rail pads.

[0064] Then, arrange each first connecting plate 4 in a row along the ship width direction, and successively hoist and place them at different positions below the cabin top plate 1, and align the guide rail center lines on each first connecting plate 4 with the guide rail center lines on the cabin top plate. As shown in Figure 3 、 4 shown, successively weld and fix the upper ends of their respective suspension rods 6 to the cabin top plate 1.

[0065] Then, arrange each guide rail segment 3 across the bottom of each first connecting plate 4, align the side ends of each guide rail segment 3, and then use fasteners to successively fix each guide rail segment 3 to the first connecting plate 4 covered by its length, that is, pass the fasteners through the first fixing holes 5 of the guide rail segment 3 and the first connecting plate to fix the guide rail segment 3 on the lower surface of the first connecting plate 4.

[0066] After the guide rail segments are fixed, install guide rail pads in the gaps between the guide rail segments 3 and the cabin top plate 1. The guide rail pads include fixed pads and adjusting pads. First, fix the fixed pads on the upper end faces of the guide rail segments, then measure the distance between the upper surface of the fixed pads and the lower surface of the cabin top plate, process the adjusting pads according to this distance, and then plug the adjusting pads into the gaps between the fixed pads and the cabin top plate and use bolts to fix the guide rail segments, fixed pads, adjusting pads and the cabin top plate into one body.

[0067] Finally, cut off the welding between the suspension rod 6 and the cabin top plate 1, and remove each first connecting plate 4, that is, remove the upper guide rail auxiliary device.

[0068] The specific steps for installing the lower guide rail by using the lower guide rail auxiliary device are as follows:

[0069] First, draw the guide rail center lines of each section of the lower guide rail on the cabin floor. The guide rail center lines on the cabin floor can be drawn by projecting the guide rail center lines on the cabin top plate as a reference, or can be drawn according to the installation positions of the partition doors marked on the construction drawings;

The partition door includes two doors symmetrically arranged along the center line of the hull. Each door includes an upper guide rail fixed on the cabin ceiling and a lower guide rail fixed on the cabin floor. The upper guide rail and the lower guide rail are both composed of multiple parallel guide rail segments, and the side ends of each guide rail segment are aligned and the midship ends are stepped.
