[0001] The invention relates to the technical field of shipbuilding, and in particular to a ship shaft system illumination positioning reference device and a use method thereof. Background Art

[0002] When installing the shafting of a conventional ship, the center line of the shafting is determined by illuminating and boring the holes. Once the boring of the shafting is completed, the axis of the entire shafting is basically determined. However, on some special ships (such as hovercraft), there is no stern tube on the shafting, and only the theoretical position of the axis of the shafting installation can be determined by illuminating and pulling the wire. When equipment needs to be installed, equipment positioning becomes a difficult problem. The existing technology relies on the height direction on the slipway and is determined by a horizontal tube. The midship direction is measured by a tape measure. The front and rear directions are determined by setting a plumb line in the direction of the input or output drive shaft of the reference equipment to be positioned, and measuring the plumb line and the fixed rib position. Positioning mainly relies on manual readings. Due to human measurement reading errors and other reasons, the reference equipment cannot be accurately positioned.
