Description

Marking device for outboard pipe perforation

Technical Field

The utility model relates to the technical field of ship manufacturing, in particular to a marking device for an outboard pipe hole.

Background

The outboard pipe which is open to the sea during the ship construction needs to be manually perforated in the field, and when the outboard pipe is in a stern linear region or the outboard pipe is not perpendicular to the straight outer plate, the intersecting line of the outboard pipe on the outer plate is not in a standard round shape. The field workers cannot effectively and directly draw the shape of the intersecting line of the outer pipe on the outer plate. At present, the common practice of all shipyards is to open a small hole at the position of an outboard pipe of an outer plate, and then to grind and expand the outboard pipe to a final open hole shape slightly based on the open hole according to a solid pipe. The method is very labor-consuming and time-consuming, and requires about 2 hours of 3 workers for the hole installation work of the outboard pipe in the line-type area according to statistics, and the final working quality is often poor, the distance between the outboard pipe and the hole edge is uneven, and even the problem of larger quality of outer plate replacement caused by out-of-tolerance of 7mm exists.
