Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, in particular to a double-bottom hold construction auxiliary device and a use method thereof. BACKGROUND

[0002] The bottom structure of a ship is divided into a single bottom and a double bottom. The single bottom has only one bottom plate, and the structure is simple and convenient to construct, and is mostly used in the bow and stern of small or medium-sized ships. The double bottom has a bottom plate and an inner bottom plate. When the bottom is damaged due to accidental situations such as grounding or stranding, the double bottom can ensure the safety of the ship. The walls in the double bottom divide the space in the double bottom into multiple functional holds, which can be used to load fuel oil, lubricating oil and fresh water or as ballast water holds.

[0003] During the construction of the double-bottom hold, each wall plate needs to be welded on the bottom plate first. After the installation of each wall plate is completed, the inner bottom plate is covered on the upper end of each wall plate. Then the workers enter each functional hold through the manhole in the middle of each wall plate, and weld and fix the top end of each wall plate to the lower end of the inner bottom plate. Since the height of each wall plate is relatively high, the workers need to stand on a stool to weld the inner bottom plate during the welding process. The workers need to get down from the stool and move the position of the stool many times during the welding process, which results in low construction efficiency. SUMMARY

[0004] The technical problem to be solved by the present application is that currently, after the inner bottom plate is covered, the workers need to stand on a stool to weld the inner bottom plate. The workers need to get down from the stool and move the position of the stool many times during the welding process, which results in low construction efficiency.

[0035] The human-carrying table 2 is arranged on the support frame and can be moved from the first manhole 101 to the second manhole 201 in a human-carrying state. Since the first manhole 101 and the second manhole 201 are both located in the middle of the functional cabin, the personnel on the human-carrying table 2 can weld the inner bottom plate, and the operating personnel do not need to stand on a stool to work, and do not need to get off the stool and move the stool position multiple times, thereby improving the construction efficiency.

[0036] The support frame is detachably connected to the first wall plate 100 and the second wall plate 200 in various ways, such as by arranging clamps at both ends of the support frame to clamp the first wall plate 100 and the second wall plate 200. In this embodiment, the first end of the support frame is provided with a first protruding portion 11 protruding outward of the support frame and extending to the outside of the first manhole 101, and the first protruding portion 11 is fixedly connected with a first magnetic seat 31, which is adsorbed on the first wall plate 100.
