Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shipbuilding, in particular to a segmented shelving and transporting portal frame. Background Art
[0002] During the shipbuilding process, block fabrication, pre-outfitting, block painting, and assembly are crucial steps. However, between these steps, block transfer and lay-up are also required. The importance of this process lies in ensuring the safety and convenience of block transfer and lay-up.
[0003] To transfer the segment, 6 to 8 sleepers are first placed on a hydraulic flatbed to ensure that the segment does not directly contact the flatbed surface during transportation, thereby reducing the risk of damage. The segment is then lifted onto the flatbed using a crane and secured to ensure its stability during transportation. Once the segment is transported to the designated location, 4 to 6 steel piers and sleepers are placed on both sides of the ground. Subsequently, the hydraulic flatbed is lowered to the appropriate height to allow the segment to be placed stably on the steel piers and sleepers. After ensuring that the segment is stable, the flatbed is removed.
[0004] This task typically requires a multi-person team effort, but even then, certain safety risks remain. Extreme caution is required during operation to avoid any potential risks, such as accidents caused by the segments slipping or becoming unstable. Furthermore, the transfer and lay-up of the segments is time-consuming, with only about two segments typically being processed in half a day. This can impact the overall construction schedule. Hydraulic flatbed trucks are expensive equipment, and if they are not fully utilized, not only will resources be wasted but also shipbuilding costs will increase.
[0005] Therefore, optimizing the process of block transfer and layup and improving the efficiency of flatbed truck utilization are of great significance to reducing shipbuilding costs. By improving operational processes and technical means, safety can be further improved, operation time can be shortened, and equipment can be fully utilized. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Embodiment: A segmented storage and transfer gantry, such as Figure 1-Figure 4 As shown, it includes a bottom plate 1, a beam foot 2, a connecting plate 3, a cross beam 4 and a side plate 6. The beam foot 2 and the cross beam 4 form an N shape. There are two beam feet 2. The two beam feet 2 are welded to the left and right sides of the bottom of a cross beam 4 through the connecting plate 3. A plurality of side plates 6 for strengthening stability are evenly welded at the connection between the connecting plate 3 and the beam foot 2. The bottom of the beam foot 2 is welded with a bottom plate 1.

Multiple reinforcing ribs 5 are welded evenly spaced between the beam foot 2 and the bottom plate 1. The reinforcing ribs 5 are a triangular structure. The stability of the triangle is used to ensure the stability between the beam foot 2 and the bottom plate 1. Multiple reinforcing plates 7 are welded symmetrically on the left and right sides of the beam 4 near the beam foot 2 to increase the strength of both ends of the beam 4 and ensure the uniformity of force between the beam 4 and the beam foot 2. Square reinforcement plates 8 are welded symmetrically on the front and back sides of the middle of the beam 4.
