Description

Technical Field

[0001] This invention belongs to the field of ship design and manufacturing technology, and specifically relates to an auxiliary installation tool for the support legs of a DJG type cable tray and its installation method. Background Technology

[0002] Cable trays are one of the main fasteners for cable laying on ships. DJG-type cable trays, characterized by their light weight, ease of manufacture, and low cost, are widely used in shipbuilding projects. For convenient transportation and storage, these cable trays and support legs are delivered separately and assembled on-site by welding. Based on previous construction experience, the current assembly of these cable trays and support legs mainly relies on a two-person work model: one person positions and stabilizes the support leg, while the other welds. This method is inefficient and prone to weld misalignment and unevenness, leading to rework.

[0003] Therefore, how to provide a support leg auxiliary installation tool and installation method for DJG type cable trays, simplifying the two-person operation into a single-person operation, freeing up labor, improving the quality and accuracy of installation, and reducing rework has become an urgent technical problem to be solved.
