Abstract

The invention discloses a segmented transportation method for a hatch coaming. The segmented transportation method comprises the following steps that two gantries are placed on the ground in parallel; hoisting equipment is used for hoisting and placing the hatch coaming section by section on the portal frame; the flat car is moved to the bottoms of the two gantries, and the gantries are shored through a shoring mechanism of the flat car; a supporting device is arranged on each portal frame to support the corresponding hatch coaming subsection; and the hatch coaming is transported to a designated position in a segmented mode through a flat car. When the hatch coaming sections are transported, the supporting device is used for supporting the hatch coaming sections, the supporting effect can be achieved, the supporting device does not need to be welded to the hatch coaming sections, the workload of cutting, grinding and the like during follow-up dismounting of the supporting device is reduced, and the working efficiency is improved. And meanwhile, the structure of the hatch coaming section cannot be damaged during dismantling, and the structural integrity of the hatch coaming section is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a hatch coaming segmental transportation method and a supporting device thereof. Background technique [0002] When transporting the hatch coaming sections, in order to prevent the sections from toppling over, the hatch coaming sections and the door frame will be connected through channel steel, but many hatch coaming sections are crack-stopping steel, and the channel steel cannot be directly welded on On the panel frame of the hatch coaming section, stainless steel connecting plates need to be welded on the panel frame of the hatch coaming first, and then the channel steel is welded on the connecting plate and the door frame. Such a connection method not only increases the welding workload, but also damages the base metal when the connection plate is removed, causing damage to the hatch coaming section. Contents of the invention [0003] In view of this, the present inve...
